An automatic water pollution treatment ship

Abstract

This invention discloses an automatic water pollution treatment vessel, comprising a main vessel, an auxiliary vessel, and a buoy. The main vessel includes a front end with at least a 180° opening, a waste storage bin, and a conveyor belt. One end of the conveyor belt is located at the front end, and the other end extends above the waste storage bin. The bottom of the buoy is provided with slats, and at least part of the slats are underwater. One end of the buoy is connected to the main vessel, and the other end is connected to the auxiliary vessel. The auxiliary vessel is configured to tow the buoy and move it, enclosing a portion of the water surface to form a wrapping area facing only the front opening. As the auxiliary vessel continues to move, it pushes the wrapping area towards the front, gradually shrinking it. This allows for large-scale water surface cleaning in one operation, improving work efficiency. At the same time, it avoids disturbing the water surface and causing waste to drift away during the main vessel's moving cleaning. The enclosing cleaning also reduces the accuracy requirements for fixed-point waste identification, making it more convenient and reliable in practice.

Description

Technical Field

[0001] This invention relates to the field of water pollution treatment technology, specifically to an automated water pollution treatment vessel. Background Technology

[0002] With the impact of human activities, various lakes and river basins suffer from varying degrees of water pollution, mainly including pollution from floating debris and illegal discharge of various types of sewage. Currently, floating debris is primarily handled through salvage. Most existing salvage vessels directly collect polluted floating debris into their holds, then transport it to the shore, where it is transferred manually or mechanically to land-based waste treatment plants. To save labor costs, many existing technologies utilize remotely controlled or automatically moving cleaning vessels. These vessels include conveyor belts for collecting debris and waste storage bins. As the vessel moves, it continuously collects and transports debris along its path to the storage bins, achieving surface cleaning. While this eliminates the need for manual salvage, it only allows linear salvage along the path, requiring continuous movement of the entire vessel, wasting energy, and resulting in low salvage efficiency. Furthermore, the movement easily disturbs the water surface, causing debris to drift away, necessitating repeated movements for complete removal and increasing salvage time. Therefore, there is an urgent need for an automated water pollution treatment vessel to address these issues. Summary of the Invention

[0003] The purpose of this invention is to provide an automated water pollution treatment vessel to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an automatic water pollution treatment vessel, comprising a main vessel, an auxiliary vessel, and buoys; the main vessel includes:

[0005] The front end must be open at least 180°.

[0006] Waste storage bins;

[0007] A conveyor belt, one end of which is located at the front end and the other end extends above the waste storage bin; and

[0008] The bottom of the buoy is provided with a strip plate, and at least part of the strip plate is underwater. One end of the buoy is connected to the main ship and the other end is connected to the auxiliary ship. The auxiliary ship is configured to move the buoy and enclose part of the water surface to form a wrapping area that opens only towards the front end. As the auxiliary ship continues to move, it pushes the wrapping area to gradually shrink towards the front end.

[0009] Preferably, a semi-circular leading edge plate is provided at the front end, and the top of the leading edge plate floats on the water surface, while the bottom is smoothly connected to the bottom of the front end through an arc-shaped plate. The arc-shaped plate is used to guide objects on the edge of the leading edge plate to move towards the bottom of the front end.

[0010] Preferably, a pair of arc-shaped wing plates are installed on both sides of the leading edge plate. The arc-shaped wing plates are rotatably connected to the leading edge plate, and a driving device is installed at the rotatable connection point. The driving device is used to drive the arc-shaped wing plates to swing around the rotatable connection point; and

[0011] The state of the arc-shaped wingplate includes:

[0012] In the convergence state, the drive device drives the arc-shaped wing plate to swing at 0-90° with the tangent of the leading edge plate. The arc-shaped wing plate is used to converge objects toward the front end when the main ship is moving.

[0013] In the limited position, the driving device drives the arc-shaped wing plate to swing at an angle greater than 90° with the tangent of the leading edge plate. The arc-shaped wing plate is used to cooperate with the float to form an enclosing area that only faces the front opening and prevents objects in the enclosing area from falling out.

[0014] Preferably, the main vessel further includes a storage compartment, the floats are foldable, and a return mechanism is provided within the storage compartment. The return mechanism is configured to:

[0015] As the auxiliary vessel moves, the buoys are released to extend and expand.

[0016] When the auxiliary vessel is reset, the buoy is pulled to fold and retract into the storage compartment.

[0017] Preferably, the return mechanism includes:

[0018] The first traction cable has several loops at the top of the buoy along the extension direction, and a connecting block is installed at the top of the buoy near the auxiliary vessel. The first traction cable passes through all the loops and is connected to the connecting block.

[0019] The second traction cable has a through hole in the center of the bar plate along the telescopic direction, and one end of the second traction cable passes through the through hole and is connected to the bar plate near the auxiliary vessel.

[0020] The first and second winding structures are used for winding or releasing the first and second traction cables, respectively; and

[0021] The lengths of the first and second traction cables are not less than the length of the float when fully deployed.

[0022] Preferably, there are two waste storage bins, and each of the two waste storage bins has multiple storage boxes slidably installed inside, each storage box comprising:

[0023] The top frame is slidably installed inside the waste storage compartment;

[0024] A bottom filter screen is fitted onto the bottom of the top frame;

[0025] as well as

[0026] Each of the storage bins is configured to slide one by one to the end of the conveyor belt as needed to receive objects output from the conveyor belt.

[0027] Preferably, an airbag is installed at the opening of the top frame, and an inflation port is provided on the outer side of the top frame. The inflation port is connected to the airbag, and a one-way valve is installed inside the inflation port. An inflation mechanism is installed on the sliding path of the waste storage bin away from the end of the conveyor belt. The inflation mechanism includes an air pump and a telescopic cylinder. A hose is installed at the output end of the air pump, and a connector is installed at the end of the hose. The connector is installed at the telescopic end of the telescopic cylinder. The telescopic cylinder is configured to drive the connector to move toward the inflation port and insert it into the inflation port to inflate the airbag through the air pump, or to detach and move away from the inflation port. When the airbag is inflated, it blocks the opening of the top frame.

[0028] Preferably, the waste storage bin has chutes on both sides, and a slider is provided on the top frame at a position corresponding to the chutes, the slider being slidably installed in the chutes; and a pushing mechanism is provided in the waste storage bin, the pushing mechanism being used to control each of the storage bins to slide in the chutes in a specified direction.

[0029] Preferably, the waste storage bin has a U-shaped structure, and the opening of the U-shaped structure is a release port. When the pushing mechanism controls the storage bin to move to the release port, the storage bin detaches from the waste storage bin.

[0030] Preferably, an extension plate is provided on one side of the release port, one end of the extension plate is hinged to the waste storage bin, and the other end is connected to the interior of the waste storage bin through an elastic structure; and the extension plate is provided with an extension groove collinear with the chute; and

[0031] The extension plate extends at least a portion of the distance into the release port at its hinge point with the waste storage bin; the extension plate is configured such that:

[0032] As the storage box moves toward the release port, the slider at one end of the storage box slides into the extension groove and squeezes the extension plate to swing toward the side of the waste storage compartment.

[0033] As the storage box moves to the release port, one side of the storage box detaches from the waste storage compartment, and the elastic structure resets, causing the extension plate to swing and push the storage box away from the release port.

[0034] Beneficial effects: This invention, through the cooperation of a main ship, an auxiliary ship, and a buoy, can achieve two working modes. The first mode is autonomous surface cleaning by moving the main ship. The second mode is that the main ship remains stationary while the auxiliary ship moves the buoy, which encloses a certain area of ​​the water surface, wraps up the garbage in that area, and gathers it towards the front of the main ship for cleaning. This mode can clean a large area of ​​the water surface at once, improving work efficiency. At the same time, it avoids disturbing the water surface and causing garbage to drift away when the main ship moves to clean. The encirclement cleaning also reduces the accuracy requirements for garbage point identification, making it more convenient and reliable in practice.

[0035] This invention allows for the partitioned storage of cleaned waste using multiple storage bins. Combined with the release port, the bins filled with waste can be easily removed. An airbag is installed at the top frame opening; this airbag, along with an inflation mechanism, inflates the bins when they are full, blocking the top frame opening and preventing waste from detaching during transport. The bins can also be released onto the water surface during operation, remaining afloat with the airbags keeping the bins closed, thus reducing the main vessel's weight. Subsequent retrieval of the bins is simply a matter of salvaging them. Attached Figure Description

[0046] The embodiments of the present invention will now be described with reference to the accompanying drawings. The terminology used in the embodiments section is for illustrative purposes only and is not intended to limit the scope of the invention. The embodiments of this application will now be described with reference to the accompanying drawings.

[0047] Example 1: Reference Figures 1-2 As shown: An automatic water pollution treatment vessel includes a main vessel 1, an auxiliary vessel 2, and a buoy 3;

[0048] refer to Figures 1-2 As shown, the main vessel 1 has a front end 4 on one side and a garbage storage bin 5 on the other side. One end of a conveyor belt 6 is located at the front end 4, and the other end extends above the garbage storage bin 5. After the main vessel 1 is launched, the end of the conveyor belt 6 at the front end 4 is submerged underwater. The opening of the front end 4 has at least a 180° opening to allow garbage from different locations on the water surface to be gathered at the end of the conveyor belt 6. The conveyor belt 6 continuously transports garbage located on the water surface at the front end 4 to the top of the garbage storage bin 5, and then outputs it to the garbage storage bin 5 below for storage. (Reference) Figure 3 As shown, a strip 31 is provided at the bottom of the float 3, and the strip 31 is at least partially underwater. One end of the float 3 is connected to the main ship 1, and the other end is connected to the auxiliary ship 2. The auxiliary ship 2 is configured to move the float 3 and enclose part of the water surface to form an enclosed area that only opens towards the front end 4. As the auxiliary ship 2 continues to move, it pushes the enclosed area towards the front end 4 to gradually shrink.

[0049] Among them, reference Figures 1-2 As shown, a semi-circular front edge plate 41 is provided at the front end 4, and the top of the front edge plate 41 floats on the water surface, while the bottom is smoothly connected to the bottom of the front end 4 through an arc plate 42. The arc plate 42 is used to guide objects on the edge of the front edge plate 41 to move toward the bottom of the front end 4.

[0050] refer to Figures 1-2As shown, a pair of arc-shaped wing plates 7 are installed on both sides of the leading edge plate 41. The arc-shaped wing plates 7 are rotatably connected to the leading edge plate 41, and a driving device 8 is installed at the rotatable connection. The driving device 8 is used to drive the arc-shaped wing plates 7 to swing around the rotatable connection.

[0051] The 7 states of the curved wingplate include:

[0052] In the convergence state, the drive device 8 drives the arc-shaped wing plate 7 to swing at 0-90° tangent to the leading edge plate 41. The arc-shaped wing plate 7 is used to converge objects toward the front end 4 when the main ship 1 moves.

[0053] In the limited position, the drive device 8 drives the arc-shaped wing plate 7 to swing at a tangent greater than 90° with the leading edge plate 41. The arc-shaped wing plate 7 is used to cooperate with the float 3 to form an enclosing area that opens only towards the front end 4 and prevents objects in the enclosing area from falling out.

[0054] This embodiment includes two working modes:

[0055] The first method: The main ship 1 performs routine cleaning work. This mode is the same as the routine cleaning mode of the cleaning ship. The drive device 8 controls the arc-shaped wing plate 7 to be in a converged state and adjusts the angle of the arc-shaped wing plate 7 according to specific needs. A monitoring module is set at the end of the leading edge plate 41 to monitor the forward direction in real time. When the main ship 1 moves, the garbage on the water surface will float to the conveyor belt 6 at the front end 4. The conveyor belt 6 will pick up the garbage and transport it to the garbage storage bin 5. The arc-shaped wing plate 7 will also capture the floating garbage on both sides and guide it to the front end 4 for retrieval.

[0056] The second method is a comprehensive cleanup operation. The drive unit 8 controls the arc-shaped wing plate 7 to be in a limited position. The main vessel 1 moves to the area to be cleaned and then stops. The auxiliary vessel 2 starts, pulling the buoy 3 and the strip plates 31. The buoy 3 gathers and encloses the garbage on the water surface, and the strip plates 31 gather and enclose garbage in a certain area below the water surface. (Reference) Figure 4 As shown, the auxiliary vessel 2 can first move to the arc-shaped wing plate 7 on one side, and then move in a fan-shaped path in front of the leading edge plate 41 to completely enclose the area in front of the leading edge plate 41. After that, it can move to the arc-shaped wing plate 7 on the other side and then move in a straight line. At this time, due to the length limitation of the float 3, as the auxiliary vessel 2 moves and is limited by the arc-shaped wing plates 7 on both sides, the float 3 in front of the leading edge plate 41 will gradually converge towards the leading edge plate 41 until it is completely converged at the leading edge plate 41. At this time, the garbage in the area enclosed by the float 3 will be gathered to the front end 4 and transported to the garbage storage bin 5 by the conveyor belt 6. After one retrieval is completed, the auxiliary vessel 2 can move in the opposite direction to reset and wait for the next encirclement operation.

[0057] Among them, the movement path of the auxiliary vessel 2 can be flexibly controlled according to the needs, and it can target and collect garbage in a certain area. Compared with conventional collection, it is more efficient and avoids the main vessel 1 moving and disturbing the water surface, causing garbage to drift away. It also reduces the accuracy requirements for garbage point identification, making it more convenient and reliable in practice.

[0058] Example 2, based on Example 1, with reference to Figures 5-6 As shown, the main vessel 1 also includes a storage compartment 9, the floats 3 are foldable structures, and a return mechanism is installed inside the storage compartment 9. The return mechanism is configured as follows:

[0059] As the auxiliary vessel 2 moves, the buoy 3 is released to extend and expand.

[0060] When the auxiliary vessel 2 is reset, the buoy 3 is pulled to fold and retract into the storage compartment 9.

[0061] In this embodiment, the return mechanism includes a first traction cable 10 and a second traction cable 11, as well as a first winding structure and a second winding structure. The first and second winding structures are located inside the main vessel 1 (not shown in the figure) and use a conventional motor to drive the winding wheel. One end of the first traction cable 10 and the second traction cable 11 are respectively wound around the first and second winding structures, and the winding and unwinding of the first traction cable 10 and the second traction cable 11 are controlled by the first and second winding structures. Figure 3 As shown, the top of the float 3 is provided with several loops 32 along the extension direction, and a connecting block is installed at the top of the float 3 near the auxiliary vessel 2. The first traction cable 10 passes through all the loops 32 and is connected to the connecting block. The center of the strip 31 is provided with a through hole 33 along the extension direction, and one end of the second traction cable 11 passes through the through hole 33 and is connected to the strip 31 near the auxiliary vessel 2. The lengths of the first traction cable 10 and the second traction cable 11 are not less than the length of the float 3 after it is fully extended.

[0062] Initially, the float 3 is folded and stored in the storage compartment 9. When the auxiliary vessel 2 moves, the first and second winding structures simultaneously release the first traction cable 10 and the second traction cable 11. At this time, the auxiliary vessel 2 can pull the float 3 to unfold and extend it out of the storage compartment 9. As the auxiliary vessel 2 moves, the first and second winding structures continuously release until the float 3 is fully unfolded. When the auxiliary vessel 2 returns to its original position, the first and second winding structures simultaneously wind up the first traction cable 10 and the second traction cable 11, pulling the float 3 back into the storage compartment 9. The float 3 can be moved to a state where it is collinear with the storage compartment 9 (in this embodiment, a U-shaped channel storage compartment 9 is used, but other shapes can also be used as needed). Then, the first and second winding structures simultaneously wind up the first traction cable 10 and the second traction cable 11, which can quickly and effectively retract the float 3 back into the storage compartment 9.

[0063] Example 3, based on Example 1 and / or 2, with reference to Figures 1-2 As shown, there are two waste storage bins 5. In this embodiment, the waste storage bins 5 are arranged on both sides of the return mechanism, but they can also be arranged on the same side as needed. When arranged on both sides, a triangular separation guide block 12 is provided at the point where the conveyed waste is about to approach the return mechanism to guide the conveyed waste toward the waste storage bins 5 on both sides; Reference Figure 1 As shown, multiple storage boxes 13 are slidably installed in both waste storage bins 5. Each storage box 13 includes a top frame 131 and a bottom filter screen 132. The top frame 131 is slidably installed in the waste storage bin 5. The bottom filter screen 132 is fitted onto the bottom of the top frame 131. The top frame 131 is used to maintain a certain opening so that waste can fall stably into the bottom filter screen 132 below. The bottom filter screen 132 can be set to be detachable for easy replacement and cleaning. Each storage box 13 is configured to slide to the end of the conveyor belt 6 as needed to receive objects output from the conveyor belt 6.

[0064] The waste storage bin 5 has chutes 14 on both sides, and a slider (not shown in the figure, but installed in the chutes 14 for movement) is mounted on the top frame 131 at a position corresponding to the chutes 14. The slider is slidably installed in the chutes 14. A pushing mechanism 15 is also provided inside the waste storage bin 5 to control each storage bin 13 to slide in a specified direction within the chutes 14. (Reference) Figure 4 As shown, in this embodiment, the waste storage bin 5 has a U-shaped structure. The pushing mechanism 15 is located at the end of the waste storage bin 5 away from its opening, below the conveyor belt 6. The pushing mechanism 15 has the same structure as a conventional telescopic cylinder 18, and its extension and retraction direction is the same as the slider movement direction. Figure 4 For example, the right side of the figure shows a schematic diagram of the pushing mechanism 15 pushing the storage box 13. Under normal conditions, the pushing mechanism 15 and the storage box 13 are both located below the conveyor belt 6. The pushing mechanism 15 pushes the bottom storage box 13 upward vertically. Since the storage boxes 13 are in direct contact, they will push all the storage boxes 13 upward synchronously. In the initial state, the first storage box 13 is located below the output end of the conveyor belt 6. When it is full, the pushing mechanism 15 works to push all the storage boxes 13 upward and push the next storage box 13 to be located below the output end of the conveyor belt 6. This process is repeated so that the pushing mechanism 15 can push all the storage boxes 13 past the output end of the conveyor belt 6.

[0065] Furthermore, based on this embodiment, refer to Figure 4 and Figure 7As shown, an airbag is installed at the opening of the top frame 131, and an inflation port 16 is provided on the outside of the top frame 131. The inflation port 16 is connected to the airbag, and a one-way valve 161 is installed inside the inflation port 16. The waste storage bin 5 is equipped with an inflation mechanism on the sliding path of the storage box 13 away from the end of the conveyor belt 6. The inflation mechanism includes an air pump 17 and a telescopic cylinder 18. A hose 19 is installed at the output end of the air pump 17, and a connector 20 is installed at the end of the hose 19. The connector 20 is installed at the telescopic end of the telescopic cylinder 18. The telescopic cylinder 18 is configured to drive the connector 20 to move toward the inflation port 16 and insert it into the inflation port 16 to inflate the airbag through the air pump 17, or to detach and move away from the inflation port 16. When the airbag is inflated, it blocks the opening of the top frame 131.

[0066] refer to Figure 4 As shown, the area below the conveyor belt 6 of the garbage storage bin 5 is the first storage area, and the area above it is the second storage area. The first storage area is used to store the storage bin 13 that has not received garbage, and the second storage area is used to store the storage bin 13 that is full of garbage. Taking the second storage area as an example with four storage stations, the station closest to the conveyor belt 6 is the first storage station, and the stations above it are the second, third and fourth storage stations. The first storage station is used to receive the garbage output from the conveyor belt 6. The inflation mechanism is set at the corresponding position of the second storage station. When the pushing mechanism 15 pushes the storage bin 13 to the second storage station, the telescopic cylinder 18 can be extended to drive the plug to be inserted into the telescopic cylinder 18. The air pump 17 works to inflate the airbag. The inflated airbag will block the opening of the top frame 131. The inflation of the airbag can prevent the stored garbage from falling out of the storage bin 13 during the movement, thus improving stability. An air outlet can also be set on the top frame 131 to release the gas in the airbag as needed.

[0067] Further, refer to Figure 4 As shown, the U-shaped structure opening is the release port 21, that is, the work station is above the fourth storage station. When the pushing mechanism 15 controls the storage box 13 to move to the release port 21, the storage box 13 is separated from the garbage storage bin 5; so that the user can quickly remove the storage box 13 filled with garbage from the main ship 1.

[0068] The main vessel 1 can also be detached synchronously while moving, releasing the garbage-filled storage box 13 onto the water surface to reduce the load on the main vessel 1. The floating storage box 13 can then be retrieved by the cleanup personnel. The storage box 13 can float on the water surface through an inflated airbag, or a floating plate or other structure can be installed in the top frame 131 as needed.

[0069] Example 4, based on Example 3, in order to improve the release effect of storage tank 13 and prevent storage tank 13 from remaining at release port 21 during water surface release operation, refer to Figure 1As shown, an extension plate 22 is provided on one side of the release port 21. One end of the extension plate 22 is hinged to the waste storage bin 5, and the other end is connected to the inside of the waste storage bin 5 through an elastic structure 24. The extension plate 22 is provided with an extension groove 23 that is collinear with the slide chute 14. The extension plate 22 extends into the release port 21 at least a partial distance from the hinge point between it and the waste storage bin 5. This allows the storage bin 13 to contact the extension plate 22 when it is still inside the waste storage bin 5, i.e., when both sides of the storage bin 13 are restricted by the waste storage bin 5. The extension plate 22 is configured such that: as the storage box moves toward the release port 21, the slider at one end of the storage box slides into the extension groove 23 and squeezes the extension plate 22 to swing toward the side of the garbage storage bin 5; as the storage box moves to the release port 21, one side of the storage box disengages from the garbage storage bin 5, and at this time the elastic structure 24 on the other side resets and drives the extension plate 22 to swing, giving the storage box 13 a force to move and push the storage box away from the release port 21. This thrust can provide the storage box 13 with an initial velocity, forcing it to move away from the main ship 1.

An inflation mechanism is installed on the sliding path of the waste storage bin away from the end of the conveyor belt. The inflation mechanism includes an air pump and a telescopic cylinder. A hose is installed at the output end of the air pump, and a connector is installed at the end of the hose. The connector is installed at the telescopic end of the telescopic cylinder. The telescopic cylinder is configured to drive the connector to move toward the inflation port and insert it into the inflation port to inflate the airbag through the air pump, or to detach and move away from the inflation port. When the airbag is inflated, it blocks the opening of the top frame.

6. The automatic water pollution treatment vessel according to claim 5, characterized in that: The waste storage bin has chutes on both sides, and a slider is provided on the top frame at a position corresponding to the chutes. The slider is slidably installed in the chutes. The waste storage bin is also equipped with a pushing mechanism, which is used to control each storage bin to slide in the chutes in a specified direction.

7. The automatic water pollution treatment vessel according to claim 6, characterized in that: The waste storage bin has a U-shaped structure, and the opening of the U-shaped structure is a release port. When the pushing mechanism controls the storage box to move to the release port, the storage box is detached from the waste storage bin.

8. The automatic water pollution treatment vessel according to claim 7, characterized in that: An extension plate is provided on one side of the release port. One end of the extension plate is hinged to the waste storage bin, and the other end is connected to the interior of the waste storage bin via an elastic structure. The extension plate also has an extension groove collinear with the chute. The extension plate extends at least a portion of the distance into the release port at its hinge point with the waste storage bin; the extension plate is configured such that: As the storage box moves toward the release port, the slider at one end of the storage box slides into the extension groove and squeezes the extension plate to swing toward the side of the waste storage compartment. As the storage box moves to the release port, one side of the storage box detaches from the waste storage compartment, and the elastic structure resets, causing the extension plate to swing and push the storage box away from the release port.
