The present application relates to an apparatus to collect materials such as waste, organic materials and objects inadvertently lost on or near the surface of water, in particular, a floating marine vessel for collecting such waste.
Waste, such as plastic bottles, plastic bags and other detritus, and even hydrocarbons such as leaked oil are increasingly present in the world's water bodies. There are different ways to collect floating waste in harbors, water reservoirs (lakes, ponds), rivers (rivers, canals) and coastal areas.
There are manual solutions where workers maneuver motorized boats, collect the waste with a dip net and store them in bins. For hydrocarbons, floating dams can be used to contain pollution. Absorbent fabrics can be used to absorb the hydrocarbon or oil waste. These materials are then collected and treated. Dispersants can also be used to reduce an oil slick to fine particles that disperse in water. A vacuum head, weir skimmer or brush skimmer can also be used to collect oil spills.
Mechanized solutions include vehicles specifically designed to perform clean-up operations. These vehicles, maneuvered by on-board human operators, are able to collect floating wastes by a grid bucket and to collect the hydrocarbons by separating them from the water. Since at least 2016, a method taking a form of a submerged suction bin immersed in water that sucks all types of floating waste has been in use.
The submerged suction bin solution has the advantage of being able to operate continuously without the need for a human operator at all times (except to recover the waste collected) but the collection perimeter is very small (a few meters). It is necessary to multiply the equipment for treating large areas. In addition, the power consumption required to power all the pumps to suck the waste continuously then becomes considerable.
Robotic solutions can include wire-guided waste collection modules. This type of module allows the recovery of waste located in port corners, which can be hard to reach and between parked boats. These can include an aquatic drone that collects floating waste in aquatic areas. Current solutions based on wire-guided devices make it possible to collect wastes remotely but remain difficult to implement in congested and/or remote areas because of the permanent link between the machine and the operator. In addition, each machine requires an operator to control the movements. The cost of using these devices remains high, which makes it difficult to envisage the collection of waste in large areas.
Another robot accumulates the waste between its two hulls but once returned to the base, the accumulated waste is dumped in one place. Then the waste must be picked up again. In addition, in the event of reverse movement, current or waves, wastes can easily come out of the robot. However, the weight of the robot can be considerable so it is difficult or impossible to put it in the water or take it out by one person. The length of the drone can be 1.56 meters. A robot of this size is difficult to transport and launch. Access to tight spaces (in the corners and between boats) is extremely complicated for such a large robot.
Another robot of 1.2 meters long have a duration of use between two refills limited to 2 hours. Its collection capacity is very limited because the waste collector is an articulated landing net. Waste recovery is done manually by emptying the landing net already attached to the robot.
Manual waste collection is still a widely used solution for cleaning aquatic areas with significant human resources. These operations therefore have a significant cost for communities or port managers, which limits the frequency and completeness of clean-up operations. In addition, this exposes workers to significant health risks in contact with pollutants.
Thus, there is a need for marine apparatus for waste collection that is highly maneuverable, man-portable and has a waste collection system that can be easily accessed by a user and reduces overall cost of operation.
In accordance with an exemplary embodiment of the disclosure a marine apparatus for collecting waste, can include a vessel frame; at least one float mounted on the vessel frame; a removable frame configured to receive a waste collector; at least one guide mounted on either the vessel frame or the removable frame; and at least one slide mounted on the other of the vessel frame or the removable frame, said at least one slide including a channel closed at one end and open at an opposite end, the open end forming a receiving end for receiving a respective guide.
Additional features and advantages of the invention will be set forth or be apparent from the description that follows. The features and advantages of the invention will be realized and attained by the structures and methods particularly pointed out in the written description and claims hereof as well as the appended drawings. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation without limiting the scope of the invention as claimed.
Several preferred embodiments of the invention are illustrated in the enclosed Figures in which:
Propulsion of the marine apparatus 100 can be provided by longitudinal motor-driven propellers 114 for providing a forward, reverse and/or rotational movement to the marine apparatus 100. A transverse propeller 116 can be provided for imparting a lateral movement to the marine apparatus 100. The speed of the propellers can be variable so that the marine apparatus can be operated at a variety of speeds.
Arranged in each float is a battery compartment 108 for holding at least one suitably sized battery and electronic materials to provide power for operating the propellers. The battery compartment and/or the battery should be suitable for a marine environment including proper seals. A recharger inlet 104 is provided on the vessel frame 101 so that the batteries can be charged while in place in the battery compartment 108. A start/stop switch 102 is provided on the vessel frame 101 to place the marine apparatus 100 in condition for operation. Each of the longitudinal and transverse propellers can be provided with a guard 118. The guard 118 protects the propellers from underwater objects and also provides a platform for resting the marine apparatus 100 on a firm surface. The propulsion system is not limited and can be any suitable system for powering, propelling and steering the marine apparatus.
According to an exemplary embodiment of the disclosure, the marine apparatus 100 can be operated via a user handheld remote controller 120 emitting, for example, radio frequency control signals, to control the motors that drive the respective propellers via the control command box 119. The marine apparatus can have a suitable antenna for receiving the control signals. According to an exemplary embodiment of the disclosure, the marine apparatus may operate as a robot including a preprogrammed or random route. In another exemplary embodiment according to the disclosure, the controller 120 can be linked to sensors or receivers provided on the marine apparatus which can assess the operational environment and define its own route. The exemplary embodiments of the disclosure can be implemented by at least one processor (e.g., general purpose or application specific) of a computer processing device which is configured to execute a computer program tangibly recorded on a non-transitory computer-recording medium, such as a hard disk drive, flash memory, optical memory or any other type of non-volatile memory. Upon executing the program, the at least one processor is configured to perform the operative functions of the exemplary embodiments by controlling the individual motors of the respective propellers.

The longitudinal slides 208 are formed by first and second arms 302a, 302b which are substantially parallel (i.e. within ±15°). A channel 304 is formed between the arms 302a, 302b. The arms 302a, 302b are contiguous at a closed end and at an opposite end form an open end open to the channel 304. The longitudinal slides 208 can be provided in pairs and are spaced apart on the vessel frame 101 at a distance to accommodate the removable frame 200. By providing the longitudinal slides 208 as separate entities with no direct links, the effect of water drag on movement of the marine apparatus 100 can be limited. This also allows flexibility in the type of removable frame 200 which may be attached to the longitudinal slides 208. In another exemplary embodiment, the longitudinal slides 208 can be mounted on the removable frame 200. A space between the floats 112 for receiving the removable frame 200 should be sized to accommodate the removable frame 200 as well as the longitudinal slides 208. If the longitudinal slides 208 are mounted on the vessel frame 101, then guide pins 404 are arranged on the removable frame 200. If the longitudinal slides 208 are mounted on the removable frame 200, then the guide pins 404 are mounted on the vessel frame 101.
The longitudinal slides 208 each include a first guide surface 306a and a second and third guide surfaces 308a and 308b arranged to guide pins 404 mounted on either of the vessel frame 101 or the removable frame 200, into the channel 304 arranged between the first arm 302a and second arm 302b. The first guide surface 306a and the second and third guide surfaces 308a and 308b are inclined towards the respective open ends formed by the arms 302a, 302b of the longitudinal slides 208. The second guide surface 308a is formed on the second arm 302b. The first guide surface 306a can be attached to the longitudinal slide by any suitable method, for example, riveting or welding.
The first guide surface 306a arranged on a longitudinal slide 208 on one side of the vessel frame 101/removable frame 200 is inclined inwardly toward a respective channel 304 and toward a longitudinal slide 208 on an opposite side of the vessel frame 101/removable frame 200. A fourth guide surface 306b provided on the longitudinal slides 208 is inclined toward the respective open ends and is arranged to easily guide pins 404 out of the channel 304 when the removable frame 200 is extracted.

According to an exemplary embodiment of the disclosure, the removable frame can be provided with the guide pins 404 positioned at different heights. For instance, a series of holes can be provided along the side portions of the frame, and the pins can be placed in desired holes to vary the depth at which the frame extends into the longitudinal slides before the lower pins abut the bottom of the channels 304. In this way, the position of the removable frame 200 relative to the water surface can be adjusted depending on the type of waste to be collected.
In various exemplary embodiments according to the disclosure, the length of the removable frame 200 can be made longer or shorter (lengths or widths) to provide different collection capacities dependent upon the circumstances.
According to exemplary embodiments of the disclosure, the marine apparatus can be arranged in different configurations. As shown in
