Compared with the prior art, the technical solutions of the present invention have following beneficial effects.
According to the present invention, the pneumatic ship comprises the floating body and the pneumatic propulsion device arranged on the floating body, wherein: the floating body is suitable for floating on the water surface and has a relatively small self-weight; and, through arranging the pneumatic propulsion device on the floating body, the airflow is directly formed to generate the propulsive force, so as to push the pneumatic ship. Through pushing the pneumatic ship by the airflow, the debris in the water is prevented from entering the pneumatic ship and an influence of the water flow direction is also avoided. Therefore, with the above pneumatic ship, the actions of steering and moving become more flexible, the cost is relatively low, and the reliability is relatively high. The pneumatic ship provided by the present invention can come into life and be used for the daily recreation.
Furthermore, through the sensing mechanism arranged on the floating body, the user operation is sensed and the sensing signal is generated; and through the controller which controls the pneumatic propulsion device according to the sensing signal, the user can conveniently operate the floating body, thereby improving the user experience.
Furthermore, through arranging the pneumatic propeller with the changeable jet direction at the fore part of the floating body and arranging the pneumatic propeller having the jet direction consistent with the direction of the middle part pointing to the tail part fixedly at the tail part of the floating body, it is merely required to adjust the pneumatic propeller arranged at the fore part of the floating body when changing the direction, so as to improve the stability of the pneumatic ship when changing the direction.
Furthermore, through the sensor arranged on the upper surface of the floating body, the gravity center change of the user is measured and the sensing signal is generated; then the pneumatic propeller is controlled according to the sensing signal, so that the control of the user on the pneumatic ship becomes more intelligent and the user has a better experience when surfing with the pneumatic ship.
Furthermore, the wireless signal receiver coupled with the controller is arranged and receives the remote signal from the controller, and controls the pneumatic ship according to the remote signal, so as to realize the remote control of the pneumatic ship and broaden the application field of the pneumatic ship. For example, the pneumatic ship can be applied in fields of unmanned detection and unmanned rescue. In the above fields, the pneumatic ship generally does not have the relatively large load-bearing but requires the flexible operation. The pneumatic ship provided by the present invention is relatively light and has the flexible control, which greatly meets the requirements of the above fields.
Furthermore, the acoustic wave sensor coupled with the controller is arranged, and the controller controls the jet direction of the pneumatic propeller according to the signal outputted by the acoustic wave sensor, so as to control the course of the pneumatic ship and provide the basis of the automatic cruise according to the acoustic wave. The pneumatic ship can be further applied in the unmanned rescue.
Furthermore, the thickness of the edge of the floating body is smaller than the thickness of the center of the floating center; the lower surface of the floating body protrudes towards the water surface; the pneumatic ship further comprises the plurality of jet mechanisms arranged at the edge of the floating body; and the jet mechanisms are suitable for jetting towards the water surface. When the jet mechanisms jet towards the water surface, the pressure between the pneumatic ship and the water surface is decreased, so that the resistance during the sailing process is decreased and the pneumatic ship can be applied in various environments such as in the water and marsh.
Furthermore, the attitude measuring mechanism is arranged, and the jet mechanisms are controlled according to the attitude signal generated by the attitude measuring mechanism after measuring, so as to maintain the balance condition of the pneumatic ship and improve the safety of the pneumatic ship.
Furthermore, through arranging the airflow condition measuring mechanism, the working conditions of the pneumatic propeller and the jet mechanisms are measured; and, the controller controls the pneumatic propeller or the jet mechanisms with the abnormal working condition to stop working, so that the further damage to the pneumatic propeller or the jet mechanisms with the abnormal working condition is avoided when the pneumatic ship sails in the complex environment.
Furthermore, the cutting mechanism is arranged and able to cut the foreign matter such as the water plant which stops the movement of the pneumatic ship, so that the sailing reliability of the pneumatic ship is increased.
Furthermore, when the floating body serves as the surfboard, the pneumatic propeller is arranged on the surfboard. When surfing with the pneumatic ship provided by the present invention, the requirements on the natural conditions of the surfboard are decreased; and, when the sea wave is relatively small, the pneumatic propeller can be used for accelerating, so as to improve the surfing experience of the user.
As described above, a ship which is pushed to move forward through air jet generally cooperates with an air cushion formed below the ship, so as to decrease a resistance of a water surface and increase a sailing speed. The above pneumatic ship is also called the hovercraft, which is often applied in a field of transportation.
The above hovercraft has a relatively large volume and power consumption, and a relatively poor control flexibility and energy-saving performance, so that an application range thereof is limited.
In another technical solution of a ship having a relatively high flexibility, in order to obtain a relatively large propulsive force, a propeller driven by a motor is arranged below the water surface, and meanwhile a water inlet and a water outlet are arranged. The propulsive force is generated by a water flow from the water inlet to the water outlet through a rotation of the propeller. The above technical solution requires the propeller to form the flow, so that foreign matter in water is easily attached to the propeller, which has a relatively poor reliability.
According to the preferred embodiments of the present invention, a pneumatic ship is provided, comprising a floating body and a pneumatic propulsion device arranged on the floating body, wherein: the floating body is suitable for floating on the water surface and has a relatively small self-weight; and, the pneumatic propulsion device is arranged on the floating body and directly generates the propulsive force through forming airflow, so as to push the pneumatic ship. Through pushing the pneumatic ship by the airflow, debris in the water is prevented from entering the pneumatic ship and an influence of a water flow direction is also avoided. Therefore, with the above pneumatic ship, actions of steering and moving become more flexible, and a cost is relatively low. Moreover, because an air outlet of the pneumatic propulsion device is located above a waterline, the debris in the water is prevented from entering the pneumatic ship, so that the pneumatic ship has a relatively high reliability.
With a social development, differentiated demands of different social groups become more and more. The pneumatic ship provided by the present invention can come into life and be used for daily recreation, and can also be applied in fields of unmanned rescue, unmanned detection, unmanned delivery and scientific investigation, which has a relatively wide application range.
In order to make objects, features and beneficial effects of the present invention more apparent and understandable, the preferred embodiments of the present invention are described in detail with the accompanying drawings as follows.
According to the first preferred embodiment of the present invention, the pneumatic propulsion device is embodied as a pneumatic propeller 12.
The floating body 11 is suitable for floating on a water surface. The floating body can be embodied as a surfboard. A user can stand, kneel or lie on an upper surface of the floating body 11, namely a surface where a pattern “B” shown in
In other embodiments of the present invention, the floating body can be the surfboard of other shapes. One skilled in the art can understand that: all of the floating bodies that can be used for surfing belong to the surfboard, such as an inflatable rubber cushion, a rowboat and a kayak. However, an application range of the pneumatic ship provided by the first preferred embodiment is not limited to surfing.
A length of the floating body is limited to six meters, and a width thereof is limited to two meters.

With the above pneumatic ship, the user can change an attitude of the floating body through adjusting an own body posture, so as to adjust a sailing direction of the pneumatic ship. The operations are same or similar as operations adopted by the user when surfing. When surfing with the above pneumatic ship, it is relatively easy for the user who can surf expertly with a conventional surfboard to master operative skills.
Moreover, when surfing with the pneumatic ship provided by the first preferred embodiment, because of a propulsion effect of the pneumatic propeller of the pneumatic ship, requirements on natural conditions of the surfboard are decreased. When a sea wave is relatively small, the pneumatic propeller can be utilized for accelerating, so as to improve a surfing experience of the user.
One skilled in the art can understand that: the pneumatic propeller 12 is exemplary only; a specific structure and shape of the pneumatic propeller can be different from that shown in
Moreover, the pneumatic propeller can also be a jet propeller, a compressed air system with a fan or other types of propellers that can form the airflow to provide the propulsive force. Correspondingly, the air outlet of the pneumatic propeller can be an air jet outlet or an air outlet of the fan in the compressed air system. The above various pneumatic propellers generate the propulsive force through forming the airflow. For description convenience, in the present invention, the various ways for generating the airflow are all called jet, and jet is not the limitation of the specific way for generating the airflow.
In other embodiments of the present invention, the air outlet of the pneumatic propeller can also be located at a position of “A3” shown in
The number of the pneumatic propeller matches with a size and a weight of the floating body, so that the pneumatic propeller becomes suitable for generating the propulsive force to push the floating body to move.

That is to say, in the specific application, the pneumatic ship comprises the floating body and the pneumatic propulsion device, wherein: the pneumatic propulsion device comprises at least one pneumatic propeller; whether each pneumatic propeller belongs to the first pneumatic propulsive unit or a second pneumatic propulsive unit is determined by whether the jet direction of the pneumatic propeller can change with respect to the floating body. The pneumatic propulsion device comprises at least one of the first pneumatic propulsive unit and the second pneumatic propulsive unit.
Specifically, the first pneumatic propulsive unit comprise at least one pneumatic propeller, wherein: the jet direction of each pneumatic propeller in the first pneumatic propulsive unit is adjustable with respect to the floating body; and the jet directions of every pneumatic propeller in the first pneumatic propulsive unit can be the same or not. A jet quantity per unit time of each pneumatic propeller in the first pneumatic propulsive unit is also adjustable.
The pneumatic propulsion device can merely comprise the second pneumatic propulsive unit, wherein merely a jet quantity per unit time of the second pneumatic propulsive unit can be changed; and the second pneumatic propulsive unit comprises at least one pneumatic propeller. For example, as shown in
The pneumatic propulsion device can merely comprise the first pneumatic propulsive unit or the second pneumatic propulsive unit (as shown in
When the pneumatic propulsion device merely comprises the first pneumatic propulsive unit, a jet quantity per unit time and a jet direction with respect to the floating body of each pneumatic propeller of the pneumatic ship are adjustable, so that the pneumatic ship has a better flexibility and controllability.
When the pneumatic propulsion device merely comprises the second pneumatic propulsive unit, a control of the pneumatic ship depends on body movements of the user, a cost is relatively low and requirements of the surfing user are well met.
When the pneumatic propulsion device comprises the first pneumatic propulsive unit and the second pneumatic propulsive unit, a stability of the pneumatic ship is increased and part of the cost is decreased.
In conclusion, the pneumatic propulsion device can be arranged according to the application scene and is not limited herein.
A control of the pneumatic propulsion device is illustrated in detail as follows.
As shown in
The pneumatic propulsion device comprises at least one of the first pneumatic propulsive unit 23 and the second pneumatic propulsive unit 24. The jet direction and the jet quantity per unit time of the first pneumatic propulsive unit 23 can be both controlled by the controller 22; and, the jet quantity per unit time of the second pneumatic propulsive unit 24 can also be controlled by the controller 22.
The sensing mechanism 21 can be arranged at the floating body. The sensing mechanism 21 comprises at least one sensor which is suitable for generating the sensing signal according to the sensed user action. The sensor can be a pressure sensor, a torque sensor or an image sensor. The sensor can also be the other sensing device that can sense the user action and generate the sensing signal.
The controller 22 is suitable for receiving the sensing signal and generating the control signal according to the sensing signal, so as to control at least one of the jet direction and the jet quantity per unit time of the first pneumatic propulsive unit 23. It is also feasible that the controller generates the control signal according to the sensing signal, so as to control the jet quantity per unit time of the second pneumatic propulsive unit 24.
A control of the controller 22 on the second pneumatic propulsive unit 24 can refer to a control of the controller on the first pneumatic propulsive unit 23. The control of the controller 22 on the first pneumatic propulsive unit 23 is illustrated as follows.
In the specific application, a specific shape and structure of the sensing mechanism 21 and a configuration of the sensor are various and further described as follows.
Besides the sensor, the sensing mechanism can further comprise: a connection rod with a first end connected with the floating body; and a holding part connected with a second end of the connection rod. At the moment, a position and a type of the sensor have various choices and are illustrated as follows.
The sensors can be pressure sensors, for respectively measuring pressures withstood by the left holding part 32 and the right holding part 33. The sensor can also be two surface sensors, which respectively cover surfaces of the left holding part 32 and the right holding part 33.
A connection surface 54 is a section where the left holding part 52 and the connection rod 51 are connected. A normal direction of the connection surface 54 is obliquely connected with the connection rod. The sensor is arranged at the connection surface 54. Because the normal direction of the connection surface 54 is obliquely connected with the connection rod, a direction of the pressure measured by the sensor arranged at the connection surface 54 can reflect a force direction of the sensing mechanism more comprehensively, so as to sense the user action more accurately.
Furthermore, the sensor arranged at the connection surface can be an annular flake sensor arranged at an area 61 shown in
The connection rod and the holding part of the sensing mechanism can be integrated together or connected in other ways, such as welding and clamping.
In the specific application, the sensors of the sensing mechanism measure the pressures withstood by the left holding part and the right holding part. After obtaining the sensing signal, the controller controls the first pneumatic propulsive unit according to the sensing signal.
For example, when a resultant force of the pressures withstood by the left and right holding parts comprises a leftward component, the controller can control all or part of the pneumatic propellers in the first pneumatic propulsive unit to jet towards left rear; conversely, the controller can control all or part of the pneumatic propellers in the first pneumatic propulsive unit to jet towards right rear.
The controller can also control the jet quantity per unit time of the first pneumatic propulsive unit according to the sensing signal. For example, when the measured resultant force of the pressures withstood by the left and right holding parts is forward, the controller increases the jet quantity per unit time; when the measured resultant force is backward, the controller decreases the jet quantity per unit time.
The controller is able to judge according to specific values of the pressures withstood by the left and right holding parts, so as to adjust the jet direction and the jet quantity of the first pneumatic propulsive unit more accurately. For example, when the measured resultant force of the pressures withstood by the left and right holding parts is backward and larger than a preset value, the controller can decrease the jet quantity per unit time of the first pneumatic propulsive unit; when the jet quantity per unit time is decreased to zero, the controller can control the first pneumatic propulsive unit to jet forward, until the user implements the subsequent operation.
When the first pneumatic propulsive unit comprises a plurality of pneumatic propellers, the controller can respectively control the plurality of pneumatic propellers according to the sensing signal and configuration positions of the plurality of pneumatic propellers.
The control of the controller on the first pneumatic propulsive unit has various ways. Besides the above-described examples, the control signal can be obtained through other ways of calculating a value and a direction of the pressure measured by each sensor, and then the controller controls the first pneumatic propulsive unit according to the control signal.
The holding part of the sensing mechanism can also be spherical (referring to

The sensor generates the sensing signal according to the torque between the connection rod 81 and the floating body; and, the controller generates the control signal according to a value and a direction of the torque, so as to realize the control of the pneumatic propulsion device.
In other embodiments of the present invention, a button can be arranged at the holding part or the connection rod; through pressing the button, the user determines a sailing direction and a sailing speed.
As shown in
The floating body 91 comprises a fore part, a middle part and a tail part which are successively connected, wherein: a width of the fore part of the floating body narrows along a direction of the middle part pointing to the fore part; the tail part of the floating body is arc, and a protruding direction of the arc is a direction along the middle part pointing to the tail part.
The first pneumatic propulsive unit 92 comprises a first pneumatic propeller 921 and a second pneumatic propeller 922. The second pneumatic propulsive unit merely comprises the pneumatic propeller 93. The first pneumatic propulsive unit is arranged at the fore part of the floating body, and the second pneumatic propulsive unit is arranged at the tail part of the floating body.
The first pneumatic propeller 921 and the second pneumatic propeller 922 are connected to the floating body 91 through rotation shafts. The controller changes jet directions of the first pneumatic propeller 921 and the second pneumatic propeller 922 through driving the rotation shafts.

The controller is able to generate a control signal according to the sensing signal, so as to control the first pneumatic propulsive unit 92 and the second pneumatic propulsive unit.
The user can stand on an upper surface of the floating body 91 and holds the holding part 941 by one or two hands. When the pneumatic ship need accelerating, the user forward pushes the holding part 941; when the pneumatic ship need decelerating, the user backward pulls the holding part 941; and, when the pneumatic ship need steering, the user exerts a pressure to the holding part 941 in a specific direction.
Different user actions can be presented by the pressure between the connection rod 942 and the floating body 91, which is measured by the sensor 943. Then the sensing signal is generated according to the value and the direction of the pressure.
The controller generates the control signal according to the sensing signal generated by the sensor 943, so as to control the pneumatic propulsion device.
For example, when the sensing signal presents the pressure direction towards the front-left, the controller can control the second pneumatic propulsive unit to increase the jet quantity per unit time according to a value of a forward pressure component, control the second pneumatic propeller 922 and the first pneumatic propeller 921 of the first pneumatic propulsive unit to steer and jet towards the right rear, and meanwhile adjust the jet quantity per unit time of the second pneumatic propeller 922 and the first pneumatic propeller 921 according to a value of a leftward pressure component. During the above process, the controller can also adjust the jet quantity per unit time of the pneumatic propeller 93 of the second pneumatic propulsive unit.
For description convenience, a direction of the tail part of the floating body pointing to the fore part of the floating body is a forward direction and is taken as a standard to determine a backward direction, a leftward direction and a rightward direction.
The jet quantity per unit time of the second pneumatic propulsive unit can be smaller than that of the first pneumatic propulsive unit, so as to change the sailing direction of the pneumatic ship more stably.

A target location is determined according to a command received by the communication device; a position of the pneumatic ship is obtained through the positioning device; according to the target location and the position of the pneumatic ship, a ship route is planned; when sailing according to the planned route, combined with the image obtained by the camera 103, the obstacle is avoided.
In other embodiments of the present invention, the controller 101 can also identify the image and control the pneumatic propulsion device, so that the pneumatic ship sails towards a specific object in the image or follows the specific object in the image. The image of the specific object can be stored in advance or identified according to preset characteristics.
The pneumatic ship further comprises an acoustic wave sensor 105 coupled with the controller 101, wherein: the acoustic wave sensor 105 is suitable for receiving an acoustic wave and converting an acoustic signal into an electric signal; the controller 101 is suitable for identifying the electric signal of the acoustic wave sensor 105; when the electric signal of the acoustic wave sensor 105 meets a preset condition, the controller controls the jet direction of the pneumatic propulsion device 104 according to the electric signal outputted by the acoustic wave sensor 105, so that the pneumatic ship sails towards an acoustic source.
Whether the electric signal of the acoustic wave sensor 105 meets the preset condition can be determined through steps of: identifying the electric signal of the acoustic wave sensor 105, and thereafter determining whether content of the electric signal is a present statement in a statement library. The controller 101 can identify the electric signal of the acoustic wave sensor 105 and determine the content; when the content belongs to the statement in the statement library, such as “Help”, “Come on” and “Help me”, the content is considered as meeting the preset condition.

A control of the jet mechanisms 112 is mainly illustrated as follows. The pneumatic ship can further comprise other parts such as a controller and a pneumatic propulsion device. Detailed control ways of the parts can refer to the above description and are not repeated again.
A thickness of the edge of the floating body 111 is smaller than a thickness of a center of the floating body 111; and a lower surface of the floating body 111 protrudes towards a water surface.
The plurality of jet mechanisms 112 which are arranged at the edge of the floating body are suitable for jetting towards a carrying surface of the pneumatic ship, so as to decrease a resistance between the pneumatic ship and the water surface.
According to the third preferred embodiment of the present invention, the pneumatic ship can sail in water areas of rivers, lakes and seas, sail in marsh, and sail in a water surface covered by water plants or other plants.

For example, when the attitude measuring mechanism 122 measures that the floating body rises towards one side, the controller 121 can control the jet mechanisms 124 at the side to decrease the jet quantity per unit time, or increase the jet quantity per unit time of the jet mechanisms 124 at the other side, so as to maintain the balance condition of the pneumatic ship.
