A garbage cleaning unmanned ship

Abstract

This invention provides an unmanned surface vessel (USV) for garbage collection, comprising a hull with a retrieval device and a dumping device. The retrieval device includes a base plate and side plates fixed to both sides of the base plate. The base plate has an upward-opening V-shaped structure, and its rear end is rotatably connected to the hull. The dumping device includes a wire rope, a winch, and a motor. The motor is adapted to drive the winch to wind up or unwind the wire rope. One end of the wire rope is connected to the winch, and the other end is connected to the front end of the base plate. The USV for surface cleaning of the water surface involved in this application can adjust the tilt angle and height of the base plate through the winch, so that the front end of the base plate is below the water surface, automatically traveling to the garbage collection location to intercept surface garbage into the retrieval device. This eliminates the need for manual retrieval by personnel, improving cleaning efficiency and ensuring the personal safety of workers.

Description

Technical Field

[0001] This invention relates to the field of garbage ships, and in particular to an unmanned garbage collection vessel. Background Technology

[0002] Surface debris, also known as floating garbage, refers to various wastes floating on the surface of various bodies of water (such as lakes, rivers, and scenic water areas). This surface debris not only affects the aesthetics but also leads to the deterioration of water quality and impacts the ecological environment.

[0003] Related technologies often employ manual cleaning methods, which involve using small boats to transport workers to the location of the debris on the water surface, where workers manually remove it using tools such as tongs and nets. However, this method is not only time-consuming and labor-intensive, but also has poor safety. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide an unmanned surface vessel for garbage collection. This unmanned vessel can adjust the tilt angle and height of the bottom plate through a winch so that the front end of the bottom plate is below the water surface. It can automatically travel to the garbage collection position and intercept the garbage on the water surface into the retrieval device. There is no need for manual retrieval by staff, which can improve the cleaning efficiency and ensure the personal safety of the staff.

[0005] To achieve the above-mentioned technical features, the present invention aims to provide an unmanned garbage collection vessel, comprising a hull, characterized in that the hull is equipped with a garbage collection device and a drive device, the garbage collection device comprising a garbage bin, the drive device comprising a winch, a steel wire rope, and a slide rail fixed above the hull, the slide rail comprising a horizontal track and an inclined track, the horizontal track being higher than the inclined track, the garbage bin being slidably connected to the slide rail, and the winch being adapted to wind up or unwind the steel wire rope to adjust the position of the garbage bin.

[0006] Preferably, a limiting component is provided above the slide rail. The limiting component includes a first limiting rod, the front end of which is adapted to rotate upward under the drive of the garbage bin, and the rear end of which is adapted to restrict the movement direction of the top of the garbage bin.

[0007] Preferably, the limiting component further includes a second limiting rod, which is located above the first limiting rod, and the second limiting rod is used to limit the tilting angle of the garbage bin.

[0008] Preferably, the limiting component further includes an elastic component, one end of which is fixed to the rear end of the first limiting member, and the other end of which is fixed above the first limiting member.

[0009] Preferably, the limiting component further includes a limiting switch, which is located outside the first limiting rod.

[0010] Preferably, a collection box is provided on the top of the hull, and the collection box is located between the winch and the garbage bin.

[0011] Preferably, the collection box is provided with a hanging ring at the top and a drainage hole at the bottom.

[0012] Preferably, baffles are provided on both sides of the hull, and the baffles are located outside the garbage collection device.

[0013] Preferably, the outer side of the hull is provided with a tilting assembly, which includes a telescopic device, a support base, and an arc-shaped connector. The telescopic device includes a hydraulic rod or an electric telescopic rod. The support base is fixed to the hull. The baffle is rotatably connected to the support base. One end of the baffle near the hull is rotatably connected to the movable end of the telescopic device through an arc-shaped connector. The movable end of the telescopic device is rotatably connected to the support base through an arc-shaped connector.

[0014] Preferably, the baffle is provided with rollers on the side away from the hull.

[0015] The present invention has the following beneficial effects:

[0016] This invention provides an unmanned surface vessel (USV) for garbage collection, comprising a hull, a garbage collection device, and a drive mechanism. The garbage collection device includes a garbage bin, and the drive mechanism includes a winch, a steel cable, and a slide rail fixed above the hull. The slide rail includes a horizontal track and an inclined track, with the horizontal track higher than the inclined track. The garbage bin is slidably connected to the slide rail. The winch is adapted to wind up or unwind the steel cable to adjust the position of the garbage bin. Thus, the USV provided by this invention can control the movement of the garbage bin on the slide rail via the winch. This allows for timely adjustment of the garbage bin's entry depth according to the hull's draft, ensuring that surface garbage can enter the garbage bin. Furthermore, it can drive the garbage bin to the top of the slide rail for emptying, improving collection efficiency and ensuring the safety of personnel. Attached Figure Description

Detailed Implementation

[0024] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0025] Example 1:

[0026] like Figures 1-3 As shown, the unmanned garbage collection vessel provided by the present invention includes a hull 100, on which a garbage collection device 200 and a drive device 300 are provided. The garbage collection device 200 includes a garbage bin 210. The drive device 300 includes a winch 310, a steel wire rope 320, and a slide rail 330 fixed above the hull 100. The slide rail 330 includes a horizontal track and an inclined track. The horizontal track is higher than the inclined track. The garbage bin 210 is slidably connected to the slide rail 330. The winch 310 is adapted to wind up or unwind the steel wire rope 320 to adjust the position of the garbage bin 210.

[0027] The components of the drive unit 300 are arranged in pairs, symmetrically on the outside of the garbage hopper 210. The winch 310 is fixed by a mounting base at the bottom. The horizontal and inclined tracks in each slide rail 330 are smoothly connected.

[0028] The garbage bin 210 is higher at the front and lower at the back, and can be slidably connected to the slide rail 330 via any one of the following: bearing, slider, or pulley. Taking the bearing as an example, fixed rods 211 can be symmetrically arranged on both sides of the garbage bin 210, and bearings 212 are installed on the outside of the fixed rods 211. The size of the bearings 212 is adapted to the width of the slide rail 330.

[0029] Of course, considering structural stability, each side of the garbage bin 210 can be equipped with two fixing rods 211 of different heights, arranged with the front lower than the back. For example... Figure 3 As shown, a fixing rod 211 is installed at the top rear end of the garbage bin 210, and another fixing rod 211 is installed at the lower middle part of the garbage bin 210. Each fixing rod 211 has a bearing 212 of the same size installed on its outer side. Correspondingly, each slide rail 330 includes two parallel tracks. This avoids the risk of the garbage bin rotating around a single fulcrum when tilted and moving along the slide rail, potentially scattering garbage onto the water surface, as there is only one fulcrum on each side of the garbage bin.

[0030] To avoid repetition and ensure readability, the following description will use the example of two fixed rods of different heights installed on each side of the garbage bin. It should be noted that this should not be considered a limitation of the invention.

[0031] One end of the wire rope 320 is fixed to the winch 310, and the other end is fixedly connected to the front end of the garbage bin 210. Specifically, hanging ears 213 are symmetrically installed on both sides of the garbage bin 210, and the wire rope 320 is fixed to the hanging ears 213. The hanging ears 213 are connected to the garbage bin 210 through connecting rods. When retrieval of garbage, the bottom of the garbage bin 210 is below the water surface. When dumping garbage, the winch 310 winds up the wire rope 320, and the wire rope 320 pulls the garbage bin 210 to move on the slide rail 330. When the garbage bin 210 moves from the inclined track to the horizontal track in the slide rail 330, its bottom rotates, rotating around the bearing 212 on the rear fixed rod 211, realizing automatic dumping of garbage at the end of the slide rail 330.

[0032] For ease of installation, a bracket 110 can be installed at the end of the horizontal track in the slide rail 330. The slide rail 330 is fixed by the bracket 110. Preferably, the bracket 110 is provided with a pulley, and the wire rope 320 passes through the pulley and is fixed to the front end of the garbage bin 210.

[0033] The hull 100 is equipped with a controller and power supply, which is used to control the drive unit 300.

[0034] The unmanned garbage-collecting vessel provided by this invention can control the garbage bin to move on the slide rail via a winch. On the one hand, it can adjust the water depth of the garbage bin in a timely manner according to the draft of the vessel, ensuring that garbage on the water surface can enter the garbage bin. On the other hand, it can drive the garbage bin to the top of the slide rail to dump the garbage. The cleaning is not limited by time and manpower, which can improve the cleaning efficiency. It can also be used to clean up dangerous or hard-to-reach waters, reducing the safety risks to workers.

[0035] In a preferred embodiment of the present invention, the center of gravity of the garbage bin is located at the front end and its weight is greater than a threshold. The threshold can be, for example, 5 kg, 8 kg, 10 kg, etc., and can be determined according to the size and dimensions of the garbage bin. As mentioned above, the garbage bin dumps garbage at the end of the slide rail. Without external force or machinery, the garbage bin may remain on the horizontal track and unable to slide down. Controlling the position and weight of the garbage bin's center of gravity allows the winch to wind up the wire rope, and the garbage bin to slide downwards on the slide rail by its own weight. Preferably, a limiting block is provided at the bottom of the inner side of the slide rail. The limiting block is positioned higher than the bearing at the lower position on the side of the garbage bin. This ensures that the garbage bin will not detach from the track at the bottom of the slide rail when it slides downwards.

[0036] The garbage bin can be tipped over with the help of a limiting component. For example... Figure 2 As shown, a limiting component 400 is provided above the slide rail 330. The limiting component 400 includes a first limiting rod 410. The front end of the first limiting rod 410 is adapted to rotate upward under the drive of the garbage bin 210, and the rear end of the first limiting rod 410 is adapted to restrict the movement direction of the top of the garbage bin.

[0037] The limiting component 400 is parallel to the slide rail 330 and can be mounted on the bracket 110, located inside the slide rail 330. The components of the limiting component 400 can be installed in pairs.

[0038] The first limiting rod 410 is wider at the front and narrower at the back, with an arc-shaped rear end, and is rotatably connected to the bracket 110 via a rotating shaft 411. The distance between the rotating shaft 411 and the rear end of the first limiting rod 410 is equal to the straight-line distance from the rotating shaft 411 to the bottom of the horizontal slide rail 330.

[0039] When collecting garbage, the first limiting rod 410 is in a horizontal position. As the garbage hopper 210 rises, the front end of the first limiting rod 410 contacts the garbage hopper 210 and can rotate upward under the push of the garbage hopper 210. As the top bearing 212 of the garbage hopper 210 enters the end of the slide rail 330, the end of the first limiting rod 410 rotates downward, which can lock the fixing rod 211 connected to the top bearing 212 of the garbage hopper 210. This prevents the top bearing 212 from derailing or sliding downward, and then the steel wire rope 320 can continue to be wound up. Relying on the steel wire rope 320 to pull the front end of the garbage hopper 210 to rotate, the garbage is dumped. To better control the movement trajectory of the first limiting rod 410, a boss can be set on the periphery of the fixing rod 211 of the garbage hopper 210. The lateral width of the boss matches the width of the front end of the first limiting rod 410.

[0040] In a preferred embodiment of the present invention, the limiting component 400 further includes a second limiting rod 420, which is located above the first limiting rod 410 and is used to limit the flipping angle of the garbage bin 210.

[0041] The second limiting rod 420 is adapted to abut against the left and right side plates of the garbage bin 210 or parts installed on the side plates. There can be two second limiting rods 420, arranged in pairs on both sides of the garbage bin 210. The horizontal distance between the two second limiting rods 420 can be equal to or slightly greater than the horizontal distance between the left and right side plates of the garbage bin 210. It is understood that if the top bearing 212 on the side of the garbage bin 210 moves to the end of the slide rail 330 and the wire rope 320 continues to be wound, the garbage bin 210 may become upside down on the slide rail 330 or derail. The second limiting rods 420 control the maximum tilting angle of the garbage bin 210, ensuring that the garbage bin 210 can empty garbage after tilting and subsequently return to the bottom of the slide rail 330 under gravity.

[0042] Preferably, such as Figure 2 As shown, the second limiting rod 420 has a groove at its front end. The groove is adapted to the connecting rod at the hanging ear 213. After the top bearing 212 of the garbage bin 210 moves to the end of the slide rail 330, the wire rope 320 can continue to pull the front end of the garbage bin 210 to rotate to complete the garbage dumping. As the garbage bin 210 rotates, the connecting rod is engaged in the groove, the garbage is poured onto the boat, and the winding of the wire rope 320 can be stopped.

[0043] The first limiting rod 410 can be reset by an elastic component (not shown in the figure). One end of the elastic component is fixed to the rear end of the first limiting member, and the other end of the elastic component is fixed above the first limiting member.

[0044] The elastic component includes either a spring or elastic rubber.

[0045] The elastic component is used to reset the first limiting rod 410, and can drive the end of the first limiting member to rotate when the garbage bin 210 slides down.

[0046] When the first limiting component 400 is not in contact with the garbage bin 210, the elastic component is in its natural state. After the first limiting component 400 rotates upward, the elastic component is in a stretched and extended state. When the garbage bin 210 slides down, the elastic component automatically contracts, which can drive the end of the first limiting component to rotate, loosening the restriction on the top fixing rod 211, allowing the bearing 212 to slide within the track.

[0047] To improve the sensitivity of the device, a limit switch 430 can be added, which is located outside the first limit rod 410.

[0048] Limit switch 430 is used to limit the maximum tilting angle of the first limit rod 410 and can be installed above the middle of the first limit rod 410. When the off signal of limit switch 430 is detected, the controller can control the winch 310 to stop winding the wire rope 320.

[0049] In a preferred embodiment of the present invention, a collection box 500 is provided on the top of the hull 100, and the collection box 500 is located between the winch 310 and the garbage bin 210.

[0050] Collection bin 500 is used to store the garbage retrieved from garbage bin 210.

[0051] In a preferred embodiment of the present invention, the top of the collection box 500 is provided with a hanging ring, and the bottom of the collection box 500 is provided with a drainage hole.

[0052] like Figure 1 As shown, baffles 600 are provided on both sides of the hull 100, and the baffles 600 are located outside the garbage collection device 200.

[0053] The baffles 600 are used to collect garbage and can be fixedly installed on both sides of the hull 100. There are two baffles 600, which open outward at a certain angle, and the two baffles 600 are the same size.

[0054] Of course, a fixed baffle 600 would hinder the passage of the unmanned waste collection vessel in narrow waterways, and its waste collection capacity is limited. To improve the maneuverability and waste collection efficiency of the unmanned waste collection vessel, a movable baffle 600 can be installed.

[0055] Preferred, such as Figure 4 and Figure 5 As shown, a tilting assembly 700 is provided on the outer side of the hull 100. The tilting assembly 700 includes a telescopic device 710, a support base 720, and an arc-shaped connector 730. The telescopic device 710 includes a hydraulic rod or an electric telescopic rod. The support base 720 is fixed on the hull 100. The baffle 600 is rotatably connected to the support base 720. One end of the baffle 600 near the hull 100 is rotatably connected to the movable end of the telescopic device 710 through an arc-shaped connector 730. The movable end of the telescopic device 710 is rotatably connected to the support base 720 through an arc-shaped connector 730.

[0056] There are two arc-shaped connectors 730, which are identical in shape and size. The sum of the central angles of the two arc-shaped connectors 730 is approximately 360°. A rotating rod can be installed on the movable end of the telescopic device 710, the support base 720, and the baffle 600. One end of each of the two arc-shaped connectors 730 is connected to the rotating rod on the movable end of the telescopic device 710, and the other end is connected to the rotating rod on the support base 720 and the baffle 600, respectively. Square through holes can be provided on the support base 720 and the baffle 600. These square through holes are used to accommodate the arc-shaped connectors 730.

[0057] In this way, when the unmanned garbage collection vessel is sailing or docking, the baffle can be retracted to fit tightly against the outside of the hull. When collecting garbage, the baffle can be driven to rotate, causing it to flip from the outside of the hull to the front of the hull, gathering the garbage around the hull to the front of the retrieval device, thus collecting garbage more efficiently.

[0058] Preferably, the baffle 600 is provided with a roller 610 on the side away from the hull 100.

[0059] When the unmanned waste collection vessel docks, it can be placed in a dock for charging. The dock has guide grooves on both sides. Rollers 610 are adapted to roll in the guide grooves, allowing the unmanned waste collection vessel to enter a preset position in the dock.
