Description

Technical Field

[0001] This invention relates to the field of water conservancy and cleaning technology, and in particular to a device and method for cleaning floating debris in water bodies. Background Technology

[0002] In the operation of water conservancy and hydropower projects, the removal of floating debris from the water body is an important task. If these floating debris are not removed in a timely manner, they may have many adverse effects on the normal operation of water conservancy projects, water environment quality, and equipment safety, such as clogging water intakes, affecting hydropower generation efficiency, and disrupting the ecological balance.

[0003] Current floating debris removal devices still have some shortcomings. In particular, the collection of floating debris is not easy to retrieve, which greatly delays work efficiency in practical applications. For example, some devices collect floating debris, but it is difficult to remove it quickly and conveniently. The operation of retrieving floating debris is cumbersome and requires a lot of manpower and time, failing to meet the needs of efficient cleaning operations. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a device and method for cleaning floating objects in water, which facilitates the collection of floating objects and thus improves work efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A water debris removal device includes an outer shell with floating wheels mounted on the left and right sides at the lower end of the outer shell. An inner shell is slidably disposed within the outer shell and raised and lowered by a submersible mechanism. A squeezing mechanism is provided on the inner front side of the inner shell, which presses floating debris into the inner shell. A collection bucket is placed inside the rear of the inner shell, with its top extending out of the outer shell. A collection mechanism is provided on the side of the collection bucket near the squeezing mechanism, which opens or closes the collection port of the collection bucket. A propeller is installed at the tail end of the inner shell.

[0006] The extrusion mechanism includes a first extrusion roller and a second extrusion roller. The first extrusion roller and the second extrusion roller are arranged laterally on the inner shell and are driven to rotate by a gear transmission mechanism and a first motor in opposite directions.

[0007] The inner shell at the front end of the extrusion mechanism is provided with an outwardly expanding feed inlet; the inner shell is provided with slope guide blocks corresponding to the upper and lower parts of the extrusion mechanism.

[0008] The bottom plate of the collection bucket has a first leakage hole, and the bottom plate of the inner shell has a set of second leakage holes.

[0009] The diving mechanism includes a second motor mounted on a first U-shaped frame. The second motor is connected to a lead screw, which is threaded to a square threaded cylinder. The square threaded cylinder freely passes through the through hole of the outer shell and is connected to the upper end of the inner shell.

[0010] The collection mechanism includes a winding shaft, which is rotatably mounted on the top of the collection bucket and driven by a third motor; winding discs are installed on the winding shaft at intervals on the left and right, one end of the pull rope is wound on the winding disc, the other end of the pull rope is connected to the outer end of the rotating plate, and the inner end of the rotating plate is hinged to the bottom of the collection bucket.

[0011] A protective box is fixedly connected to the upper surface of the outer casing, and a battery pack is installed inside the protective box.

[0012] The outer shell has vertical slots corresponding to the propeller and the extrusion mechanism.

[0013] A handle is rotatably connected to the top of the collection bucket.

[0014] A method for cleaning floating debris in water includes the following steps: Step 1: Moving the device to the working position: When in use, the device can be pushed to a suitable working position on the shore by the action of the four floating wheels; the floating wheels allow the device to float on the water and be easily moved to the area where floating objects need to be cleared. Step 2, Inner Shell Submersion: When the working position is reached and cleaning work is about to begin, the submersion mechanism is activated; the second motor in the submersion mechanism drives the lead screw to rotate; the rotation of the lead screw will drive the square threaded cylinder downward, thereby driving the inner shell and its connected components to submerge together. When the submersion reaches the point where the water level is between the first and second squeeze rollers, the submersion mechanism stops working; Step 3, Floating Object Cleaning and Squeezing: After stopping the submersible mechanism, start the squeezing mechanism and propeller; the first motor of the squeezing mechanism works, and through the gear transmission mechanism, the first squeezing roller and the second squeezing roller rotate in opposite directions; at the same time, the propeller starts to propel the device to move in the water; the floating objects smoothly enter between the first squeezing roller and the second squeezing roller through the feed port and the slope guide block, and the floating objects are squeezed by the rotation of the two squeezing rollers. Step 4, Floating Object Collection: As the device moves and the squeezing operation continues, the squeezed floating objects will enter the rotating plate and be squeezed and pushed into the collection bucket; the collection bucket will gradually fill with floating objects. Step 5, Closing and Squeezing the Collection Bucket: When the collection bucket is full, start the collection mechanism. The third motor will work, and the pull rope will begin to wind up and pull the rotating plate upward until the rotating plate is vertical and closes to the collection bucket, thus closing the collection bucket. Step 6, Collection Bucket Removal and Reset: After remotely controlling the device to the shore, remove the collection bucket from the inner shell to complete the collection and removal of floating debris; after emptying the garbage, put the collection bucket back into the inner shell, restart the collection mechanism, the third motor reverses, and the pull rope is released; the rotating plate rotates steadily downwards under its own weight, returns to the initial horizontal position, and opens the feed port of the collection bucket, completing the reset and preparing for the next cleaning operation.

[0015] This invention provides a device and method for cleaning floating debris in water, which has the following technical advantages: 1) This invention effectively solves the technical problems of cumbersome, time-consuming, and labor-intensive collection operations in existing water conservancy and hydropower floating debris cleaning devices by setting a detachable collection bucket and matching handle and collection mechanism inside the inner shell. Specifically, when the collection bucket is full, the operator only needs to hook the handle with an external hook to quickly remove it, avoiding the cumbersome steps of disassembling complex structures or manual retrieval in traditional devices. At the same time, the collection mechanism drives the winding roller with a third motor to automatically close and squeeze the floating debris, further improving the space utilization of the collection bucket and the efficiency of floating debris handling. Compared with the prior art, this invention significantly simplifies the collection process, reduces labor costs and time consumption, and meets the needs of efficient cleaning operations.

[0016] 2) This invention achieves multi-scenario adaptability and continuous operation capability of the floating debris removal device through the coordinated design of the submersion mechanism and the squeezing mechanism. Specifically, the submersion mechanism, through the cooperation of the lead screw and the limiting slide bar, can precisely control the submersion of the inner shell and its upper components, thereby ensuring that the squeezing roller is always at the optimal working water level. At the same time, the energy system composed of photovoltaic panels and battery packs provides continuous power supply to the device, extending the single operation time and avoiding the need for frequent power supply replacements, thus maintaining efficient and stable floating debris removal performance.

[0017] 3) This invention significantly improves the floating debris removal performance of the device through the synergistic effect of the floating wheel, V-shaped plate, and slope guide block: the floating wheel provides stable buoyancy and mobility, enabling the device to be accurately positioned in the working area; the V-shaped plate efficiently gathers floating debris by expanding the contact area and guides it to the squeezing area; the slope guide block ensures that the floating debris enters the squeezing mechanism smoothly and avoids jamming. The three components together enhance the device's efficiency, adaptability, and ease of operation in collecting floating debris. Attached Figure Description

Detailed Implementation like Figure 1-4 As shown, a water debris removal device includes an outer shell 1, with a completely open lower end and a completely open front end, and an opening on one side of the upper end of the outer shell 1. A first U-shaped frame 5 is fixedly connected to the upper surface of the outer shell 1, and four floating wheels 9 are installed on the lower left and right ends of the outer shell 1 to ensure that the device floats on the water surface.

[0028] An inner shell 2 is slidably fitted inside the outer shell 1. The inner shell 2 is driven to move up and down by a diving mechanism 6. At least one set of propellers 15 is installed at the tail of the inner shell 2, and the propellers 15 are driven by a servo motor. Two sets can also be used. A slot is provided at the tail of the corresponding outer shell 1, through which the propellers 15 freely extend out of the outer shell 1, driving the device forward. The slot ensures that the propellers 15 can descend freely and synchronously when the inner shell 2 is descending.

[0029] A feed inlet 10 is installed at the head of the inner shell 2, extending beyond the open front end of the outer shell 1. Two inclined guide blocks 3 are installed vertically inside the inner shell 2, inside the feed inlet 10. A squeezing mechanism 4 is installed on the inner shell 2 between the two inclined guide blocks 3, used to press floating debris into the inner shell 2. A collection bucket 7 is placed at the tail end of the inner shell 2. A set of first leakage holes 17 are opened at the bottom of the collection bucket 7 for filtering water. The top of the collection bucket 7 extends beyond an opening on one side of the upper end of the outer shell 1. A handle 16 is rotatably connected to the top of the collection bucket 7. A collection mechanism 8 is installed on the collection bucket 7 near the squeezing mechanism 4, used to collect floating debris into the collection bucket 7.

[0030] The bottom of the inner shell 2 is provided with a set of second leakage holes 20, which are also used for water filtration.

[0031] Both the inner shell 2 and the outer shell 1 are made of engineering plastic and have their own buoyancy.

[0032] The extrusion mechanism 4 includes a first extrusion roller 401 and a second extrusion roller 402. The first extrusion roller 401 and the second extrusion roller 402 are rotatably mounted on the inner housing 2 and arranged laterally. One end of the first extrusion roller 401 extends out of the inner housing 2 and is coaxially connected to a first gear 403. One end of the second extrusion roller 402 extends out of the inner housing 2 and is coaxially connected to a second gear 404. The first gear 403 and the second gear 404 mesh. The upper end of the first gear 403 meshes with a third gear 405, which is driven by a first motor 406. The first motor 406 is installed inside the first waterproof cover 407.

[0033] An opening is also provided on the outer shell 1 at the location of the first motor 406, the first gear 403, and the second gear 404, so that when the inner shell 2 is lowered, the gear transmission mechanism of the extrusion mechanism 4 can be lowered synchronously without interfering with the outer shell 1.

[0034] When the first motor 406 is started, the first extrusion roller 401 and the second extrusion roller 402 are rotated through the gear transmission mechanism, thereby extruding floating objects in the water.

[0035] The diving mechanism 6 includes a second motor 601 mounted on the upper surface of the first U-shaped frame 5. The output end of the second motor 601 is connected to a lead screw 602. The lead screw 602 is threadedly connected to a square threaded cylinder 603. The square threaded cylinder 603 freely passes through the through hole of the outer shell 1 and is connected to the upper surface of the inner shell 2.

[0036] Preferably, the left and right sides of the inner shell 2 are provided with limiting slide bars in the vertical direction, and the limiting slide bars slide in cooperation with the sliding grooves on the inner wall of the outer shell 1.

[0037] When the second motor 601 starts, the lead screw 602 rotates, which in turn drives the square threaded cylinder 603 to move up and down, and the square threaded cylinder 603 causes the inner shell 2 to move up and down as well.

[0038] The collection mechanism 8 includes a winding shaft 801, which is rotatably connected to the mounting plate 802 at the top of the collection bucket 7 and driven to rotate by a third motor 803 on the outside of the collection bucket 7. A winding reel 804 is installed on the winding shaft 801 at intervals on both sides. A pull rope 805, made of steel wire, is wound around each winding reel 804. The pull rope 805 freely passes through a hole in the front end plate of the collection bucket 7 and connects to a rotating plate 806. The other end of the rotating plate 806 is hinged to the bottom of the collection bucket 7.

[0039] After the third motor 803 starts, it drives the winding shaft 801 to rotate, thereby releasing or rewinding the pull rope 805. After the pull rope 805 is released to a suitable length, the rotating plate 806 opens outward and downward and falls horizontally onto the bottom plate of the inner shell 2, facilitating the collection of floating debris in the water. When the pull rope 805 is rewound to a suitable length, the rotating plate 806 pours the floating debris inward and upward into the collection bucket 7 and closes the lower opening of the collection bucket 7.

[0040] Preferably, a protective box 18 is fixedly connected to the upper surface of the outer casing 1, and a battery pack 19 is installed inside the protective box 18. The battery pack 19 supplies power to each motor.

[0041] Preferably, a second U-shaped frame 11 is fixedly connected to the upper surface of the outer casing 1. Four round rods 12 are installed on the upper surfaces of the first U-shaped frame 5 and the second U-shaped frame 11. A mounting plate 13 is fixedly connected to the top of the four round rods 12. A photovoltaic panel 14 is installed on the upper surface of the mounting plate 13. The photovoltaic panel 14 is connected to the battery pack 19 through a photovoltaic controller and can charge the battery pack 19. The battery pack 19 can also be charged by an external power source.

[0042] In addition, this device is equipped with a wireless remote control system, which adopts the remote control method described in "CN202311185712 - A method for controlling the docking of a wireless remote-controlled boat, a remote-controlled boat and its system".

[0043] Working principle and process: 1) Moving the device to the working position: When in use, the device can be pushed to a suitable working position on the shore by the action of the four floating wheels 9. The floating wheels 9 enable the device to float on the water surface and be easily moved to the area where floating debris needs to be cleared.

[0044] 2) Submersion of Inner Housing 2: When the working position is reached and cleaning work is about to begin, the submersion mechanism 6 is activated. The second motor 601 in the submersion mechanism 6 operates, and its output end drives the lead screw 602 to rotate. Since the outer surface of the lead screw 602 is threadedly connected to the square threaded cylinder 603, and the square threaded cylinder 603 is installed on the upper surface of the inner housing 2, and the limiting slide strip on the side of the inner housing 2 slides in cooperation with the sliding groove inside the outer housing 1, restricting the rotation of the inner housing 2, the rotation of the lead screw 602 will drive the square threaded cylinder 603 to move downward, thereby driving the inner housing 2 and its connected components to submerge together. When the submersion reaches the point where the water level line is between the first squeeze roller 401 and the second squeeze roller 402, the operation of the submersion mechanism 6 is stopped.

[0045] 3) Floating Debris Removal and Compression: After the submersible mechanism 6 stops, the compression mechanism 4 and propeller 15 are activated. In the compression mechanism 4, the first motor 406 operates, causing the first compression roller 401 and the second compression roller 402 to rotate in opposite directions via a gear transmission mechanism. The propeller 15 starts, propelling the device forward in the water. At this time, the feed inlet 10 and the two slope guide blocks 3 come into play. The V-shaped design of the feed inlet 10 increases the contact area with the floating debris, enabling the collection of more debris. The slope guide blocks 3 ensure that the floating debris can smoothly enter between the first compression roller 401 and the second compression roller 402. The rotation of the two compression rollers compresses the floating debris, improving the cleaning efficiency.

[0046] 4) Floating Object Collection: As the device moves and the compression process continues, the compressed floating objects will enter the collection bucket 7 under the thrust generated by the propeller 15. When the collection bucket 7 is full of floating objects, it needs to be processed.

[0047] 5) Closing and Squeezing the Collection Bucket: The collection mechanism 8 is activated, the third motor 803 operates, the pull rope 805 begins to wind up and pulls the rotating plate 806 upwards until the rotating plate 806 is vertical and in contact with the collection bucket 7, closing the collection bucket 7. During this process, the rotation of the rotating plate 806 also squeezes the floating objects inside the collection bucket 7 to a certain extent, further improving space utilization.

[0048] 6) Collection Bucket Removal and Reset: After remotely controlling the device to the shore, the collection bucket 7 can be easily removed from the inner shell 2 by hooking the handle 16 with the external hook rod, completing the collection and removal of floating debris. After emptying the garbage, the collection bucket 7 is placed back into the inner shell 2, and the collection mechanism 8 is restarted. The third motor 803 reverses, and the pull rope 805 is released. The rotating plate 806 rotates steadily downward under its own weight, returning to the initial horizontal position and opening the feed port of the collection bucket 7, completing the reset and preparing for the next cleaning operation.

[0049] 7) Energy Supply: The photovoltaic panels 14 on the upper surface of the outer casing 1 can convert solar energy into electrical energy, which is stored in the battery pack 19 inside the protective box 18. The battery pack 19 can provide power to the various motors in the device. The electrical energy of the battery pack 19 can also be obtained by charging from an external power source.

[0050] Example 1 Small river floating debris cleanup In a small river about 10 meters wide and 2 meters deep, where there are many floating objects such as plastic bottles, branches, and leaves that affect the aesthetics and drainage function of the river, the operator moves the device to a suitable position in the river by manually pushing four floating wheels 9 from the bank so that it floats stably. Then, the submersion mechanism 6 is activated to submerge the inner shell 2 and its components as a whole. Because the river is shallow, the submersion mechanism 6 stops working when the waterline is between the first squeezing roller 401 and the second squeezing roller 402.

[0051] Then, the propeller 15 and the extrusion mechanism 4 are activated. The device moves forward under the propeller 15. During this forward movement, the feed inlet 10 gathers floating objects, and two inclined guide blocks 3 ensure they enter the extrusion zone. The first extrusion roller 401 and the second extrusion roller 402 in the extrusion zone squeeze the incoming floating objects as they rotate, reducing their volume. As the propeller 15 continues to advance, the squeezed floating objects enter the rotating plate 806 or the collection tank 7. After a period of time, the collection tank 7 is full, and the extrusion mechanism 4 and the propeller 15 are paused. The third motor 803 in the collection mechanism 8 is then activated, causing the rotating plate 806 to close the collection tank 7 and squeeze the internal floating objects.

[0052] Then, remotely control the device to the shore, use the external hook to hook the handle 16 to take out the collection bucket 7, empty the garbage, put it back, and then start the collection mechanism 8 to reset the rotating plate 806 in preparation for the next cleaning.

[0053] Example 2 Cleanup of floating debris in localized areas of large lakes In a localized area of ​​a large lake, approximately 5,000 square meters in size, where there is a large amount of water hyacinth, foam, and other pollutants affecting the lake's ecological environment and landscape, the equipment is transported to the target cleanup area using boats. The four floating wheels 9 are adjusted to ensure stable buoyancy. The submersion mechanism 6 is activated, causing the inner shell 2 and its connected components to submerge as a whole. The submersion mechanism 6 stops at a suitable position based on the water depth, specifically when the waterline is positioned between the first and second squeezing rollers 401 and 402.

[0054] The squeezing mechanism 4 and propeller 15 are activated, and the floating debris is processed while the device moves forward. Because of the large number of water hyacinths, the squeezing process continues for a relatively long time. The squeezed floating debris enters the collection tank 7. Once the collection tank 7 is full, the squeezing mechanism 4 and propeller 15 are stopped. The collection mechanism 8 is then activated, and the rotating plate 806 closes the collection tank 7 and squeezes the floating debris inside.

[0055] Remotely control the device to the boat docking point on the lake, use the external hook to hook the handle 16 to take out the collection bucket 7, transfer the garbage to the collection container on the boat, empty the collection bucket 7 and put it back into the inner shell 2, then start the collection mechanism 8 to reset the rotating plate 806 and continue cleaning.

[0056] Example 3 Cleaning of floating debris at the reservoir intake Near the reservoir intake, where water flow causes a large amount of wood, plastic waste, and other debris to accumulate, potentially clogging the intake and affecting the reservoir's operation, a specialized transport device is used to place the equipment on the water surface near the intake. Four floating wheels are then controlled to position the device in a suitable location close to the area where the floating debris accumulates.

[0057] The diving mechanism 6 is activated, causing the inner shell 2 and its connected components to submerge as a whole. Depending on the water depth and the position of the floating object, the diving mechanism 6 is stopped when the waterline is between the first squeeze roller 401 and the second squeeze roller 402.

[0058] The extrusion mechanism 4 and propeller 15 are activated. The first motor 406 drives the first extrusion roller 401 and the second extrusion roller 402 to rotate. The propeller 15 pushes the device to move against the direction of water flow. The feed inlet 10 and the two slope guide blocks 3 work together to guide the floating objects to the extrusion area for extrusion. The extruded floating objects enter the collection bucket 7 under the thrust of the propeller 15.

[0059] Once full, stop the squeezing mechanism 4 and propeller 15, start the collection mechanism 8, close the collection tank 7, and squeeze out the floating objects inside.

[0060] Remotely control the device to the designated area on the bank of the reservoir, take out the collection bin 7, transfer the garbage to the special processing equipment, empty the collection bin 7 and put it back into the inner shell 2, then start the collection mechanism 8 to reset the rotating plate 806 and continue cleaning.
