The present invention relates to air-cushion mine sweeping vehicles which are used for detecting positions of the underground mines particularly in defense industry.
In the state of the art, there are detectors which are carried manually by people and which perform mine sweeping by right and left oscillation of the hand while walking. However in this technique, a person should be moving very slowly in order to be able to stop when a mine is detected and this might not be possible in every situation. In addition, carrying such a detector for a certain period of time is very tiring for people.
The other current techniques are the mine sweeping technique by armored wheeled vehicles, which are used by a person and resemble construction vehicles, and mine sweeping technique by armored or unarmored wheeled vehicles which can be remotely controlled. Use of these techniques in small and narrow spaces and at places where the vehicle is required to move fast is not suitable.
The patent application numbered GB2170158A relates to mine sweeping vehicles. The application discloses a hovercraft having arms which support a rotatable flail at a safe distance in front of the hovercraft. Tilting of the hovercraft is prevented by the provision of a self-contained skirt within the main skirt of the hovercraft, the self-contained skirt being provided with air pressure from a fan at a pressure higher than the normal operating pressure of the hovercraft. As an additional feature, wheels are provided on the underneath of the hovercraft and are retractable so that they can releasably engage the surface of the ground and enable the hovercraft to be positioned precisely.
Another patent application numbered KR20150069190 discloses an air cushion vehicle for detecting and removing a mine. A propulsion unit is provided in the upper side of surface of the sea, and a mine detection unit and a control unit and a mine removal unit are installed. The said application reduces pressure reaction sensitivity of the mine since the air cushion land craft does not come in contact with the surface of the sea while the air cushion land craft moves so as to safely detect and remove the mine. Moreover, the mine sweeping work of the said application requires less cost than the mine sweeping work of a helicopter, and the air cushion land craft for detecting and removing a mine is capable of navigating in land and sea so as to rapidly navigate to a destination when an urgent situation occurs to perform the mine sweeping work.
The objective of the present invention is to provide an unmanned air-cushion mine sweeping vehicle by which underground mines are detected in an unmanned manner and the position information is recorded.
Another objective of the present invention is to visibly mark the detected positions of the mines on the ground.
In order to fulfill the said objective, the present invention comprises a mine sweeping vehicle having an arm mechanism and a detector, which is integrated to the arm mechanism and which scans the underground by an orbital movement. The mine sweeping vehicle comprises at least one data recording element that delivers the position information of the mines, which are detected by the detector, provided by a positioning system to a display element. In a possible embodiment of the invention, the positioning system is a GPS system, the data recording element is a printed circuit board and the display element is a computer. Thus, the position information of the mines provided by the positioning system is recorded and displayed on the display element, which is located at a safe distance from the mine sweeping vehicle.
In another possible embodiment of the invention, the mine sweeping vehicle comprises a first fan assembly having at least one fan that enables it to rise from the ground and at least one propeller which enables it to move in a movement direction. Thus, the mine sweeping vehicle rises away from the ground in an ascension direction and moves in a movement direction.
In another possible embodiment of the invention, the propellers are configured to be rotatable so as to enable turning of the vehicle. Hence, the mine sweeping vehicle is enabled to turn right-left.
In another possible embodiment of the invention, the vehicle comprises a second fan assembly having fans that are positioned opposite to each other and provide thrust in a the plane of the vehicle and enable turning of the vehicle. Thus, the mine sweeping vehicle is enabled to turn right-left and a thrust is provided in the opposite direction to prevent lateral slipping thereof in a slanting land.
In another possible embodiment of the invention, there is at least one sensor which provides signal to the second fan assembly. Thus, the sensors which deliver signal for activation of the second fan assembly are provided.
In another possible embodiment of the invention, the arm mechanism comprises a first arm moving away from the mine sweeping vehicle and a second arm connected to the first arm. Thus, a first arm and a second arm are provided which carry the detector at a certain distance from the front part of the mine sweeping vehicle.
In another possible embodiment of the invention, there is provided a marker which is connected to the first arm and which places a mark on the ground to show the position of the mine according to a signal received from the data recording element. This way, the detected positions of the mines on the ground are visibly marked.
In a further possible embodiment, the said marker is a paint cylinder. Thus, the position of the mine is marked on the ground via paint.
In another possible embodiment of the invention, the vehicle is a remotely controlled unmanned mine sweeping vehicle. Thus, a mine sweeping vehicle which can be remotely controlled safely is provided.
In another possible embodiment of the invention, the vehicle is a programmable autonomous mine sweeping vehicle. This way, a mine sweeping vehicle, which detects mines by scanning in a single direction on a land or narrow road, is provided.
In an alternative embodiment of the invention, the body of the mine sweeping vehicle can be provided in different geometric shapes.
In another alternative embodiment of the invention, turning of the vehicle can be enabled by the turning of the propellers to right-left or via an aerodynamic surface integrated at the back of the propellers.
In another alternative embodiment of the invention, the second fan assembly can be driven by drive members different from the ones driving the first fan assembly.
Referring to
The mine sweeping vehicle (1) comprises a first fan assembly (22) having at least one fan such that it enables the vehicle to rise from the ground in an ascension direction (H). Each fan in the first fan assembly (22) is positioned so as to be accessed through the openings provided in a fan assembly sheet (28). There is provided at least one propeller (24) connected to the rear wall (15) at a rear part of the mine sweeping vehicle (1) such that it enables the mine sweeping vehicle (1) to move in a movement direction (F). The propellers (24) are connected to the rear wall (15) via a rotary shaft that enables to direct the vehicle by turning a supporting arm (241) or the propellers. In a possible embodiment, the blades of the propellers (24) which rotate so as to provide air stream are positioned in a circular ring. There is provided a second fan assembly (23) which is located on the side walls between the front part and the rear part of the mine sweeping vehicle (1) and which has at least one fan. Each fan in the second fan assembly (23) is connected to the side wall (13) by means of a connection profile (231). The first fan assembly (22) and the second fan assembly (23) are driven by at least one drive member (25). In a possible embodiment, there are two drive members (25) which drive the first fan assembly (22) and the second fan assembly (23) independently. There is at least one sensor (27) provided in the mine sweeping vehicle (1) to provide signals to the second fan assembly (23). In a possible embodiment, the said sensor (27) is a slip sensor which detects slippage of the vehicle or its deviation from the detection orbit. At the turns of the vehicle or in slanting land, the signals received from the sensor (27) are delivered to a control circuit and the second fan assembly (23) is activated with the drive supplied by the drive members (25) via the control circuit. As the second fan assembly (23) provides a lateral thrust in the opposite direction to the slippage, the mine sweeping vehicle (1) is enabled to perform its turn or get back to its route. There is a front electronic control unit (29) in the mine sweeping vehicle (1) to control the arm mechanism (18) and the marker (19). In addition, there is a rear electronic control unit (30) which controls the drive members (25) and the second fan assembly (23).
