Description

Technical Field

[0001] This utility model relates to the technical field of underwater debris treatment equipment, and in particular to a novel rake net device for removing underwater net-like debris. Background Technology

[0002] The new type of rake net is an innovative device for efficiently removing underwater debris. Its core design combines a set of specially shaped metal rake teeth with a mesh, enabling it to quickly and accurately capture and remove floating debris, weeds, and other contaminants from the bottom. The rake tooth structure has been carefully optimized to adapt to different bottom conditions in various waters, effectively removing mud, rocks, and even complex underwater environments. Powered by either mechanical or electric drive, it simplifies operation and reduces manual labor. Through underwater vibration and rotation technology, the rake net effectively improves operational efficiency without disturbing the aquatic environment. It is widely used in aquaculture, reservoir, and lake bottom cleaning. The introduction of this new rake net significantly improves the maintenance of the aquatic ecosystem and the efficiency of bottom cleaning, bringing revolutionary improvements to underwater operations.

[0003] A search revealed Chinese Patent Publication No. CN105908796A, which discloses a novel rake net for removing underwater net-like debris. The device includes two opposing equilateral triangular side frames, with connecting rods installed between the three sets of corners of the two side frames, forming a triangular frame structure. Multiple crossbeams are installed between the three sets of sides of the two side frames, and multiple arc-shaped rake teeth are fixedly installed on the outer side of each crossbeam along its length. A mandrel is located on the outer side of the middle of each of the two side frames, with the two mandrels sharing a common center line. It also includes two left and right pull rods, with bushings fixedly installed at the inner end and lifting rings at the outer end. The bushings of each pull rod are respectively fitted onto the mandrels on both sides. This invention's rake net has a simple structure, is easy to operate, is not prone to jamming, and can rake a large amount of debris in a single operation. However, in actual use, in environments with numerous reefs or underwater structures on the seabed, the sharp corners of the triangular frame can get stuck in the crevices of the reefs or collide with the underwater structures, causing damage to the rake net or rendering it unable to function properly. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a new type of rake net for removing underwater net-like debris, aiming to improve the problem in the prior art where the sharp corners of the triangular frame get stuck in the gaps of reefs or collide with underwater structures, causing the rake net to be damaged or unable to work properly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel rake net device for removing underwater net-like debris, comprising a pull rope, a sliding cylinder fixedly connected to the left side of the pull rope, a fixed gear fixedly connected to the outer wall of the front sliding cylinder, hexagonal plates rotatably connected to adjacent sides of the two sliding cylinders, multiple rotating columns rotatably connected to adjacent sides of the two hexagonal plates, multiple rake teeth fixedly connected to the outer wall of the rotating columns, the front end of the rotating columns penetrating the front hexagonal plates and fixedly connected to a rotating gear, the multiple rotating gears meshing with the fixed gear, connecting columns rotatably connected to the inner walls of the two sliding cylinders, and a cutting mechanism provided on the outer wall of the connecting columns.

[0006] The above technical solution involves towing the device by a tugboat. Using a hoisting device on top of the tugboat, the device is lowered into the water. The tugboat is then started, and the pull rope is pulled, causing the sliding cylinder to move along with it, which in turn moves the connecting column. When the hexagonal plate contacts the seabed, it rotates during the towing process, causing the rotating column to rotate as well. This hooks up discarded netting debris. Simultaneously, the rotation of the connecting column causes a rotating gear to rotate above the fixed gear. The meshing relationship between the rotating and fixed gears allows the rotating column to rotate, further causing the rake teeth to hook and entangle the discarded netting debris, preventing it from falling off during the towing process, thus achieving a more thorough cleanup.

[0007] As a further description of the above technical solution:

[0008] The cutting mechanism includes a groove formed on the outer wall of the connecting column. A limiting U-shaped block is fixedly connected to the front side of the outer wall of the connecting column. A rotating block is rotatably connected to the inner wall of the limiting U-shaped block. A cutting blade is rotatably connected to the rear side of the rotating block. A locking U-shaped block is fixedly connected to the rear side of the outer wall of the connecting column. A limiting bolt is provided at the top of the locking U-shaped block. The outer wall of the limiting bolt penetrates the locking U-shaped block. A handle is fixedly connected to the rear side of the cutting blade.

[0009] The above technical solution involves: after hooking up a large amount of waste mesh debris, lifting the entire device, then rotating the limiting bolt to release it from the U-shaped block; pulling the handle and rotating it to rotate the cutting blade so that the sharp side of the cutting blade faces the waste mesh debris; then pulling the cutting blade around the limiting U-shaped block to cut the waste mesh debris wrapped around the rotating column, thus completing the cleaning.

[0010] As a further description of the above technical solution:

[0011] A rotating disk is fixedly connected to the opposite side of the two sliding cylinders, and the outer wall of the rotating disk is rounded.

[0012] The above technical solution reduces friction and prevents jamming and damage by rotating the disc, while the rounded treatment also protects adjacent components.

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

[0014] The outer wall of the hexagonal plate is fixedly connected to multiple buffer columns, and the outer wall of the buffer columns is rounded.

[0015] The above technical solution utilizes buffer columns for cushioning and protection, while the smooth outer wall helps reduce water resistance.

[0016] As a further description of the above technical solution:

[0017] A monitoring camera is fixedly connected to the middle of the outer wall of the rotating disk, and multiple lights are fixedly connected to the outer wall of the rotating disk.

[0018] The above technical solution allows for easy observation of equipment operation via a monitoring camera, and provides illumination for the monitoring camera via a lighting system.

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

[0020] A limiting block is fixedly connected to the rear side of the hexagonal plate, and a nameplate is fixedly connected to the rear side of the limiting block.

[0021] The above technical solution allows the device model to be recorded via a nameplate.

[0022] As a further description of the above technical solution:

[0023] The outer wall of the grip is provided with multiple anti-slip grooves, which are equidistantly spaced on the outer wall of the grip.

[0024] The above technical solution enhances anti-slip performance and reduces hand fatigue through anti-slip grooves.

[0025] As a further description of the above technical solution:

[0026] Multiple rake teeth are fixedly connected at equal intervals to the outer wall of the rotating column, and the inner wall size of the limiting U-shaped block is the same as the size of the rotating block.

[0027] The above technical solution aims to achieve uniform collection of debris during rotation, and to accurately position the rotating block and limit its range of motion.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the tugboat lowers the equipment into the water using a hoisting device. After starting, the tugboat pulls the rope, and the sliding cylinder and connecting column move accordingly. The hexagonal plate rotates in contact with the seabed, hooking up waste nets and debris. The rotation of the connecting column, through the meshing of gears and fixed gears, causes the rake teeth to wrap around the debris, ensuring thorough cleaning.

[0030] 2. In this utility model, when cleaning up waste netting debris, first lift the device, rotate the limiting bolt to release the restriction on the U-shaped block, pull the handle to make the cutting blade rotate with the sharp side facing the debris, and then pull the cutting blade to rotate around the limiting U-shaped block to cut the debris wrapped around the rotating column, thus completing the cleaning.

[0040] Specifically, the equipment is towed by a tugboat. Using the hoisting device on top of the tugboat, the equipment is lowered into the water. Then, the tugboat is started, and the pull rope 1 is pulled. This moves the sliding cylinder 3, which in turn moves the connecting column 10. When the hexagonal plate 5 contacts the seabed, it rotates during the towing process, which in turn rotates the rotating column 6, thus hooking up the discarded netting debris. At the same time, the rotation of the connecting column 10 drives the rotating gear 8 to rotate above the fixed gear 4. Utilizing the meshing relationship between the rotating gear 8 and the fixed gear 4, the rotating column 6 rotates within the rotating gear 8, further causing the rake teeth 7 to hook and entangle the discarded netting debris, preventing it from falling off during the towing process, thus making the cleanup more thorough.

[0041] Reference Figure 3 and Figure 4 The cutting mechanism 2 includes a groove 201, which is formed on the outer wall of the connecting column 10. A limiting U-shaped block 202 is fixedly connected to the front side of the outer wall of the connecting column 10. A rotating block 203 is rotatably connected to the inner wall of the limiting U-shaped block 202. A cutting blade 204 is rotatably connected to the rear side of the rotating block 203. A locking U-shaped block 205 is fixedly connected to the rear side of the outer wall of the connecting column 10. A limiting bolt 206 is provided at the top of the locking U-shaped block 205. The outer wall of the limiting bolt 206 penetrates the locking U-shaped block 205. A handle 207 is fixedly connected to the rear side of the cutting blade 204.

[0042] Specifically, after hooking up a large amount of discarded netting debris, the entire device is lifted, and then the limiting bolt 206 is rotated to release its restriction on the locking U-shaped block 205. At this time, the handle 207 is pulled and rotated, thereby driving the cutting blade 204 to rotate, so that the sharp side of the cutting blade 204 faces the discarded netting debris. Then, the cutting blade 204 is pulled to rotate around the limiting U-shaped block 202 to cut the discarded netting debris wrapped around the rotating column 6, thereby completing the cleaning.

[0043] Reference Figure 1 , Figure 2 and Figure 3 A rotating disk 9 is fixedly connected to the opposite side of the two sliding cylinders 3. The outer wall of the rotating disk 9 is rounded to reduce friction and prevent jamming and damage. The rounded surface also protects adjacent components. Multiple buffer columns 11 are fixedly connected to the outer wall of the hexagonal plate 5. The outer walls of the buffer columns 11 are rounded to provide buffer protection and reduce water resistance. A monitoring camera 12 is fixedly connected to the middle of the outer wall of the rotating disk 9. Multiple lights 13 are also fixedly connected to the outer wall of the rotating disk 9. The monitoring camera 12 can be easily observed to monitor the operation of the equipment, and the lights 13 provide illumination for the monitoring camera 12.

[0044] Specifically, the rotating disc 9 reduces friction and prevents jamming and damage. The rounded treatment also protects adjacent components. The buffer column 11 provides buffer protection. The rounded outer wall helps reduce water resistance. The monitoring camera 12 facilitates observation of the equipment's operation, and the lighting lamp 13 provides illumination for the monitoring camera 12.

[0045] Reference Figure 2 , Figure 3 and Figure 4 A limiting block 14 is fixedly connected to the rear side of the hexagonal plate 5. A nameplate 15 is fixedly connected to the rear side of the limiting block 14, which can record the model of the device. Multiple anti-slip grooves 16 are provided on the outer wall of the handle 207. The multiple anti-slip grooves 16 are equidistantly provided on the outer wall of the handle 207. The anti-slip grooves 16 can enhance the anti-slip performance and reduce hand fatigue. Multiple rake teeth 7 are equidistantly fixedly connected to the outer wall of the rotating column 6. The inner wall size of the limiting U-shaped block 202 is the same as the size of the rotating block 203. During the rotation, it can achieve uniform collection of debris. In order to accurately position the rotating block 203 and limit its range of motion.

[0046] Specifically, the nameplate 15 records the model of the device, the anti-slip groove 16 enhances the anti-slip performance and reduces hand fatigue, and achieves uniform collection of debris during rotation, in order to accurately position the rotating block 203 and limit its range of motion.

[0047] Working principle: Using a tugboat, the device is submerged in the water via a lifting device above it. After the tugboat starts, pulling the tow rope 1 causes the sliding cylinder 3 to move synchronously, thereby displacing the connecting column 10. During towing, the hexagonal plate 5 contacts the seabed and begins to rotate, thus driving the rotation of the rotating column 6. The rotation of the connecting column 10 acts on the rotating gear 8, causing it to rotate above the fixed gear 4. The meshing mechanism between the rotating gear 8 and the fixed gear 4 ensures that the rotating column 6 continues to rotate under the drive of the rotating gear 8, allowing the rake teeth 7 to effectively hook and entangle discarded netting debris, preventing… It detaches during the towing process, thus achieving a more thorough cleaning. After removing a large amount of waste netting debris through the cutting mechanism 2, the entire device is lifted out and placed above the tugboat. Then, the limiting bolt 206 is rotated to release its restriction on the locking U-shaped block 205. At this time, the handle 207 is pulled and rotated, which in turn drives the cutting blade 204 to rotate, ensuring that the sharp edge of the cutting blade 204 faces the waste netting debris. Subsequently, the cutting blade 204 is pulled to rotate around the limiting U-shaped block 202 to cut the waste netting debris wrapped around the rotating column 6, thereby completing the cleaning work.
