Description

Technical Field

[0001] This utility model relates to the field of garbage cleaning vessel technology, and in particular to the marine garbage cleaning vessel of the environmental protection guardian. Background Technology

[0002] With the increasingly serious problem of marine debris pollution, marine debris cleaning vessels have become important equipment for maintaining the marine ecological environment. These vessels bear the heavy responsibility of salvaging floating marine debris and purifying the marine environment, and their performance directly affects the efficiency of marine debris cleanup and the effectiveness of marine ecological protection. Against the backdrop of continuously improving global environmental awareness, higher requirements are placed on the functional integration, operational stability, and environmental treatment capabilities of marine debris cleaning vessels, urgently requiring technological innovation to meet the cleaning operation needs in complex marine environments.

[0003] Existing marine debris cleaning vessels are relatively traditional in terms of structural design and working principle. The hull structure is usually fixed, and the salvage operation equipment relies on simple mechanical arms or nets to collect garbage. In terms of garbage disposal, most vessels only collect and store garbage in a simple manner. For the large amount of seawater contained in the garbage, there are often no supporting treatment facilities. The mixed seawater is transported directly with the garbage, or the seawater is discharged back into the ocean without treatment.

[0004] However, traditional marine debris cleaning vessels have shortcomings. In complex sea conditions, due to the lack of effective stabilization devices, the hull is easily affected by wind and waves, causing significant swaying. This not only reduces the accuracy and efficiency of salvage operations but also endangers operational safety. At the same time, the seawater carried by the debris is discharged directly without treatment, and the residual oil, chemical pollutants, and other harmful substances in the seawater will cause secondary pollution to the ocean. This makes it impossible to fundamentally achieve the environmental goal of marine debris cleaning and fails to meet the current stringent requirements for marine ecological protection. Therefore, the Environmental Guardian marine debris cleaning vessel is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an environmental protection guardian marine garbage cleaning vessel, which aims to improve the problem in the prior art where the hull is prone to significant swaying in wind and waves, affecting salvage operations.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The environmental protection guardian marine debris cleaning vessel includes a hull, a connecting body fixedly connected to the side wall of the hull, a salvage component installed inside the connecting body, a power supply component installed on the top of the hull, and extension components installed on both sides of the hull.

[0008] The extension assembly includes multiple connecting seats 1 arranged in a symmetrical array. Each of the multiple connecting seats 1 is fixedly connected to one side of the outer wall of the hull. The other side of the four connecting seats 1 at the top and bottom is fixedly connected to a swing arm. A connecting plate is fixedly connected between the side walls of the swing arms. One end of each of the upper and lower swing arms is rotatably connected to a movable arm. A hydraulic actuator is fixedly connected to one side wall of the middle connecting seat. The output end of the hydraulic actuator is rotatably connected to the connection point of the upper swing arm and the movable arm. A connecting seat 2 is rotatably connected to the bottom of the movable arm. A float plate is fixedly connected to the bottom of the connecting seat 2.

[0009] As a further description of the above technical solution:

[0010] The retrieval assembly includes a retrieval device, and the connecting body has symmetrical connecting arms fixedly connected to its side wall. The two ends of the retrieval device are rotatably connected between the connecting arms. A conveyor belt is provided inside the connecting body for transporting waste.

[0011] As a further description of the above technical solution:

[0012] The power supply assembly includes a roof, the bottom of which is fixedly connected to the top of the hull, and multiple solar panels are fixedly connected to the top of the roof. Multiple batteries are fixedly connected to one side of the interior of the hull.

[0013] As a further description of the above technical solution:

[0014] The bottom of the hull is fixedly connected to one side of a symmetrical propeller, which is used to drive the ship's movement.

[0015] As a further description of the above technical solution:

[0016] A garbage bin is fixedly connected inside the hull. A guide plate is fixedly connected to the top of one side of the garbage bin, and a filter screen is fixedly connected to the bottom side of the inner wall of the garbage bin.

[0017] As a further description of the above technical solution:

[0018] A filter box is fixedly connected to one side of the bottom of the outer wall of the garbage bin. The filter box is located outside the filter screen. A connecting pipe is fixedly connected to the side wall of the filter box. A water pump is fixedly connected to the side wall of the connecting pipe. A drain pipe is fixedly connected to the output end of the water pump.

[0019] As a further description of the above technical solution:

[0020] The filter box has a filter element plate that is slidably connected inside. A handle is fixedly connected to the top of the filter element plate. Multiple limiting balls are provided on both the left and right sides of the filter element plate, and the limiting balls are distributed in a rectangular array.

[0021] As a further description of the above technical solution:

[0022] Each of the limiting balls has a limiting plate fixedly connected to its sidewall. The limiting plate and the outer wall of the limiting ball are slidably connected inside the filter box. A limiting spring is provided on the side of the limiting plate. One end of the limiting spring is fixedly connected inside the filter box, and the other end of the limiting spring is fixedly connected to the sidewall of the limiting plate.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, during routine operations, the output ends of the hydraulic actuators on both sides of the hull push the connection point between the movable arm and the swing arm forward, causing the swing arm to deflect and the movable arm to unfold, thus lowering the float to the point where the buoy contacts the sea surface. When the hull sways due to wind and waves, the float moves accordingly. By squeezing or stretching the output end of the hydraulic actuator at the top of the movable arm, its internal sensor adjusts the extension and retraction length in real time, achieving adaptive leveling and stabilizing of the hull. This solves the problem of traditional hulls easily swaying significantly in wind and waves, affecting salvage operations, and improves the stability of salvage operations.

[0025] 2. In this utility model, after the garbage falls into the bin, the seawater it contains flows into the filter box through the filter screen, and large debris is blocked outside. The filter plate adsorbs harmful substances in the seawater, and the filtered seawater is discharged back into the ocean through the drain pipe. When replacing the filter plate, the old plate is lifted out by the handle, and after the new plate is inserted, the limiting ball is pushed by the spring and locked into the groove to limit the position. This achieves the effect of preventing the seawater in the garbage from causing secondary pollution of the ocean, solves the problem of direct discharge of seawater containing pollutants from garbage causing secondary pollution of the ocean, and improves the marine environmental protection capacity and the environmental protection of garbage treatment.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figures 1-3This utility model provides an embodiment of an environmental protection guardian marine garbage cleaning vessel, comprising a hull 1, which is the main structure of the cleaning vessel. The hull 1 is made of high-strength, corrosion-resistant steel plate, welded and then coated with an anti-rust coating, possessing good structural strength and seawater corrosion resistance. It is used to support various components on board and navigate at sea. Connecting bodies 2 are welded to the side walls of the hull 1. The connecting bodies 2 are made of the same material as the hull 1 and have a triangular box structure. The internal space is used to install salvage components, and the external structure provides installation support for the salvage components. A power supply component installed on the top of the hull 1 provides the necessary electrical energy for the cleaning vessel's operation. The power supply component is mounted on a roof 3, which is bolted to the top of the hull 1 at its bottom. The roof 3 is fixedly connected to the top of the canopy, which is equipped with multiple solar panels 4 to convert solar energy into electrical energy. The solar panels 4 are existing technology and will not be described in detail in this article. Multiple batteries 9 are fixedly installed on one side of the hull 1 by bolts to store the electrical energy generated by the solar panels 4 and to power the various electrical equipment of the cleaning boat. The batteries 9 are existing technology and will not be described in detail in this article. Symmetrical propellers 8 are fixedly connected to one side of the bottom of the hull 1. The propellers 8 are used to convert electrical energy into mechanical energy to drive the boat forward, backward and turn on the sea surface to achieve the navigation function. The propellers 8 are existing technology and will not be described in detail in this article. The extension components set on both sides of the hull 1 are used to improve the stability of the hull 1 in wind and waves.

[0037] The extension assembly consists of multiple connecting seats 12, which are made of the same material as the hull 1 and are arranged in a symmetrical array. One side of each connecting seat 12 is welded to the outer wall of the hull 1, providing a mounting base for components such as the swing arms 13. The other side of the four upper and lower connecting seats 12 is welded to the swing arms 13. The swing arms 13 have a box-shaped cross-section for transmitting force and motion. Connecting plates 14 are welded to the sidewalls of the swing arms 13 to enhance their structural strength and stability. Movable arms 16 are rotatably connected to one end of each upper and lower swing arm 13 via pins. The movable arms 16 can rotate... The connection point rotates, and a hydraulic device 15 is fixedly connected to the side wall of a connecting seat 12 in the middle by bolts. The output end of the hydraulic device 15 is rotatably connected to the connection point of the upper swing arm 13 and the movable arm 16 by a pin, which is used to drive the movable arm 16 to move. The hydraulic device 15 is existing technology and will not be described in detail in this article. The bottom of the movable arm 16 is rotatably connected to a connecting seat 2 17 by a pin. The bottom of the connecting seat 2 17 is fixedly connected to a float plate 18 by bolts. The float plate 18 is injection molded from high-density polyethylene material and has multiple floats at the bottom. The floats are hollow structures with good buoyancy and weather resistance, which are used to provide buoyancy on the sea surface and help stabilize the hull 1.

[0038] The retrieval assembly is the core component of the cleaning vessel to achieve garbage retrieval. The retrieval device 6 of the retrieval assembly is made of high-strength stainless steel 316L. Its frame structure is formed by welding, and multiple fishing nets are set on the outer wall. Both ends are rotatably connected to the left and right symmetrical connecting arms 5 on the side wall of the connecting body 2 by pins. The connecting arms 5 are used to support the retrieval device 6 and make it rotatable. A conveyor belt 7 is installed inside the connecting body 2. The conveyor belt 7 is used to transport the garbage retrieved by the retrieval device 6 to the garbage bin 10. The retrieval device 6 and the conveyor belt 7 are existing technologies and will not be described in detail in this article.

[0039] Reference Figures 4-7The hull 1 is internally connected to a waste bin 10 by welding. The waste bin 10 is made of 304 stainless steel plate, bent and welded, which has good corrosion resistance and can adapt to the humid, saline marine environment, preventing the bin from being corroded by corrosive substances in the waste. Its internal space is used to temporarily store salvaged marine debris. A guide plate 11 is welded to the top of one side of the waste bin 10. The guide plate 11 guides the waste transported from the conveyor belt 7, ensuring it falls accurately into the waste bin 10. A filter screen 19 is welded to the bottom of the inner wall of the waste bin 10. The filter screen 19 is made of 304 stainless steel wire mesh with a mesh diameter of 2mm, used to intercept larger debris and impurities in the waste, while allowing the waste to pass through smoothly. Seawater contained in the garbage passes through the mesh, achieving initial solid-liquid separation. A filter box 20 is welded to one side of the bottom of the outer wall of the garbage bin 10. The filter box 20 is located outside the filter screen 19 and houses the filter element plate 24 for further filtration of the seawater passing through the filter screen 19. A connecting pipe 23, made of 304 stainless steel seamless pipe, is welded to the side wall of the filter box 20. This pipe transports the filtered seawater from the filter box 20 to the water pump 21. The water pump 21 is fixedly connected to the side wall of the connecting pipe 23 via a flange. The water pump 21 pressurizes the filtered seawater, causing it to be discharged overboard through the drain pipe 22. The water pump 21 is existing technology and will not be described in detail here. The output end of the water pump 21 is connected via a flange. The filter box 20 is fixedly connected to the drain pipe 22, which is made of seamless 304 stainless steel. The drain pipe 22 discharges pressurized seawater into the ocean. The filter box 20 has a sliding cavity formed inside through machining, creating a sliding fit with the filter plate 24. The filter plate 24 uses a high-strength engineering plastic frame and is filled with activated carbon and ion exchange resin composite material to adsorb harmful substances in seawater, such as oil and heavy metal ions. The filter plate 24 is existing technology and will not be described in detail here. The top of the filter plate 24 has a handle 25 integrally molded by injection molding. The surface of the handle 25 has anti-slip textures and is made of the same material as the filter plate 24 frame, facilitating the replacement of the filter plate 24. Multiple [unclear text - possibly a typo, should be removed] are provided on the left and right sides of the filter plate 24. The limiting balls 28 are arranged in a rectangular array. The limiting balls 28 are used to engage with the grooves on the side wall of the filter box 20 to fix the filter element plate 24. The side walls of the multiple limiting balls 28 are fixedly connected to the limiting plate 27 by welding. The outer wall of the limiting plate 27 forms a sliding fit with the guide groove inside the filter box 20 to limit the displacement range of the limiting balls 28. The limiting plate 27 is provided with a limiting spring 26 on its side. The limiting spring 26 is made of spring steel. One end is welded to the spring seat preset inside the filter box 20, and the other end is welded to the side wall of the limiting plate 27 to provide a reset spring force for the limiting balls 28, ensuring that the limiting balls 28 can always maintain the engaging state with the groove of the filter box 20 and ensuring the stability of the filter element plate 24 during operation.

[0040] Working principle: When using the environmental protection guardian marine garbage cleaning vessel, the solar panel 4 on the top of the canopy 3 is responsible for converting solar energy into electrical energy and storing it inside the battery 9. The battery 9 drives the propeller 8 to rotate, making the ship move. When collecting garbage, the movement of the ship and the resistance of the seawater drive the retrieval device 6 to rotate. The interception net on the retrieval device 6 collects the garbage floating on the sea surface and rotates it, causing the garbage to fall above the conveyor belt 7. The rotation of the conveyor belt 7 transports the garbage to the guide plate 11. Under the guidance of the guide plate 11, the garbage falls into the garbage bin 10.

[0041] During daily operations, the output ends of the hydraulic actuators 15 on both sides of the hull 1 push the connection point of the movable arm 16 and the upper swing arm 13 forward. The displacement of the connection point causes the swing arm 13 to deflect around the connecting seat 12, which in turn causes the movable arm 16 to unfold. The connecting seat 2 17 at its bottom drives the float 18 to move downward. When the bottom of the float 18 contacts the seawater, the float at its bottom floats on the sea surface. When encountering wind and waves that cause the hull 1 to sway, the float 18 will move up and down with the swaying direction, which in turn causes the movable arm 16 to move up or down, thereby squeezing or stretching the output end of the hydraulic actuator 15. The sensor inside the hydraulic actuator 15 adjusts the extension and retraction length of its output end in real time, achieving adaptive leveling and stabilization of the hull 1, and reducing the impact of wind and waves on salvage operations.

[0042] After the trash falls into the trash bin 10, the seawater contained inside the trash enters the filter box 20 through the filter screen 19. Larger debris and impurities are intercepted outside the filter screen 19. The filter plate 24 adsorbs harmful substances in the seawater. The filtered seawater flows into the water pump 21 through the connecting pipe 23. In the water pump 21, it is pressurized and discharged back into the ocean through the drain pipe 22. When the staff replaces the filter plate 24, they can lift the filter plate 24 by holding the handle 25 and pulling upwards. Then, the new filter plate 24 is inserted into the filter box 20. The limiting balls 28 on both sides of the filter box 20, which are squeezed, are pushed by the limiting spring 26 and locked into the grooves on the side wall of the filter plate 24, thus limiting the filter plate 24 and preventing the seawater in the trash from polluting the ocean again.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
