Description

Technical Field

[0001] This utility model relates to the technical field of river surface cleaning equipment, specifically a river surface cleaning device for water resource protection. Background Technology

[0002] River debris has caused serious damage to the river ecosystem, affecting our quality of life and health. When cleaning up river debris, we use scoop nets to remove floating objects such as water hyacinths and foam from the water surface. The scooped-up floating debris is transported to the dock for compression processing. Through regular cleaning of the river surface, we ensure that the river water is clean and tidy.

[0003] Utility model patent CN222525322U discloses a river surface cleaning device, including a gripping mechanism. A gathering baffle is fixedly connected to the end of the gripping mechanism, and the lower part of the gathering baffle is fixedly connected to one end of a connecting column. This utility model allows the fixed ring to easily drive the retrieval net to retrieve garbage from the river surface via a retrieval rod. The gathering baffle facilitates pushing the garbage on the water surface, gathering it and improving the retrieval effect of the retrieval net. The gripping handle and second rubber sleeve provide convenient gripping for the user. Pulling the lever moves the locking block within the fixed frame, allowing it to move away from the limiting blocks. At this point, the hinged fixing rod can drive the cutting head to unfold from inside the storage frame, engaging the locking block with the surfaces of the two sets of limiting blocks. This effectively limits the hinged fixing rod and the cutting head, facilitating the cutting of weeds or long pieces of garbage that are entangled in the debris.

[0004] However, the above-mentioned existing technical solutions still have the following shortcomings: when the device cuts aquatic plants or long pieces of garbage with the cutting head, the lever needs to be operated first. However, the lever is too far away from the operator's grip, so the device needs to be retracted before the lever can be operated. Furthermore, the cutting head is driven by the moving device alone, which results in poor cutting efficiency and makes it easy to encounter situations where the cutting is difficult to cut. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a river surface cleaning device for water resource protection, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a river surface cleaning device for water resource protection, including a gripping tube, an arc-shaped gathering plate fixed to the top right end of the gripping tube, an installation frame fixed to the bottom right end of the gripping tube, a retrieval net fixed to the bottom of the installation frame, a cutting mechanism provided on one side of the gripping tube, a groove opened on the surface of the gripping tube, a T-shaped operating handle slidably connected to the surface of the groove, a connecting rod fixed to the bottom of the T-shaped operating handle, and the connecting rod slidably passing through the right end of the gripping tube;

[0007] The cutting mechanism includes a support shell and two mounting shells. The support shell is fixedly connected to the right end of the connecting rod. The mounting shell is fixed to the top right side of the mounting frame. The front and rear mounting shells are arranged opposite to each other. A connecting frame is rotatably connected to the inner wall of the mounting shell. Movable plates are hinged to both the front and rear sides of the surface of the support shell. Multiple extension blocks are fixed to the surface of the movable plates. The connecting frame is hinged to the extension blocks. A back cutting blade and a front cutting blade are fixed to the left and right sides of the movable plates, respectively.

[0008] Preferably, four extension frames are fixed to the inner wall of the mounting frame, a support frame is fixed to the bottom of the extension frame, and a separation filter screen is detachably connected to the top of the support frame.

[0009] Preferably, the inner wall of the support frame is fixed with a magnet, and the frame of the separating filter is made of a magnetically attractive material.

[0010] Preferably, a protruding ring is fixed to the left end of the connecting rod, and a return spring is fixed to the surface of the protruding ring. One end of the return spring is fixedly connected to the left side of the inner wall of the gripping tube.

[0011] Preferably, the inner wall of the grip tube is fixed with multiple support plates, and the surface of the connecting rod slides through the support plates.

[0012] Preferably, a limiting plate is fixed to the inner wall of the gripping tube, and the limiting plate is located on the right side of the protruding ring.

[0013] Preferably, the distance between the bottom of the connecting rod and the top of the mounting frame is greater than the thickness of the separator filter frame.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0015] First, this utility model shortens the distance between the cutting control unit and the grip part through an integrated operation design, enabling quick one-handed operation to control the cutting blade. The cross-cutting pattern formed by the front cutting blade makes the cutting efficiency higher, and it exhibits excellent cutting performance, especially for tough aquatic plants.

[0016] Secondly, in this utility model, the three-dimensional frame structure formed by the extension frame and the support frame provides three-dimensional support for the separation filter screen. The separation filter screen can intercept garbage in layers. The four extension frames are radially distributed on the inner wall of the installation frame, which can effectively reduce the deformation of the retrieval net. When the separation filter screen needs to be cleaned, the operator only needs to lift it upwards and then move it horizontally to complete the disassembly. Attached Figure Description

[0023] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0024] Please see Figure 1-5 A river surface cleaning device for water resource protection includes a gripping tube 1, an arc-shaped gathering plate 3 fixed to the top right end of the gripping tube 1, an installation frame 4 fixed to the bottom right end of the gripping tube 1, a scooping net 5 fixed to the bottom of the installation frame 4, a cutting mechanism 2 provided on one side of the gripping tube 1, a groove 6 opened on the surface of the gripping tube 1, a T-shaped operating handle 7 slidably connected to the surface of the groove 6, a connecting rod 8 fixed to the bottom of the T-shaped operating handle 7, and the connecting rod 8 slidably passing through the right end of the gripping tube 1.

[0025] The cutting mechanism 2 includes a support shell 201 and two mounting shells 202. The support shell 201 is fixedly connected to the right end of the connecting rod 8. The mounting shells 202 are fixed to the top right side of the mounting frame 4. The front and rear mounting shells 202 are arranged opposite to each other. A connecting frame 203 is rotatably connected to the inner wall of the mounting shell 202. Movable plates 204 are hinged to both the front and rear sides of the surface of the support shell 201. Multiple extension blocks 205 are fixed to the surface of the movable plates 204. The connecting frame 203 is hinged to the extension blocks 205. A back cutting blade 206 and a front cutting blade 207 are fixed to the left and right sides of the movable plates 204, respectively.

[0026] Through the above technical solution, the operator can achieve close-range operation control by sliding the groove 6 on the surface of the grip tube 1 to the T-shaped operating handle 7. When the operator holds the grip tube 1 with one hand, the hand can pull the T-shaped operating handle 7 to the left along the groove 6, causing the connecting rod 8 to slide synchronously inside the grip tube 1. The support shell 201 fixed at the right end of the connecting rod 8 moves forward accordingly, driving the movable plates 204 hinged on the front and rear sides to rotate around the hinge point of the extension block 205 and the connecting frame 203. The connecting frame 203 set inside the mounting shell 202 serves as... The fulcrum causes the movable plate 204 to rotate during the movement, which drives the front cutting blade 207 to form a cross-cutting trajectory. During this process, the front cutting blade 207 forms a cutting action when the movable plate 204 retracts, achieving a shearing effect and effectively cutting off the obstruction. The back cutting blade 206 can increase the cutting range when the whole device moves. By coordinating the cutting action with the movement direction of the retrieval net 5, when encountering tangled aquatic plants or long strips of garbage, the operator can complete the cutting operation without changing the grip posture.

[0027] Four extension frames 9 are fixed to the inner wall of the mounting frame 4. A support frame 10 is fixed to the bottom of the extension frame 9. A separation filter screen 11 is detachably connected to the top of the support frame 10.

[0028] Through the above technical solution, the three-dimensional frame structure formed by the extension frame 9 and the support frame 10 provides three-dimensional support for the separation filter 11. The separation filter 11 can intercept garbage in layers. The four extension frames 9 are radially distributed on the inner wall of the mounting frame 4, which can effectively reduce the deformation of the retrieval net 5. When the separation filter 11 needs to be cleaned, the operator only needs to lift it up and then move it horizontally to complete the disassembly.

[0029] A magnet 12 is fixed to the inner wall of the support frame 10, and the frame of the separation filter 11 is made of a magnetic material.

[0030] With the above technical solution, when the separator filter 11 is placed in place, the magnetic attraction of the magnet 12 generates a vertical holding force, ensuring that no displacement occurs during the operation, and the magnetic fixation makes the replacement operation time of the separator filter 11 shorter.

[0031] A protruding ring 13 is fixed to the left end of the connecting rod 8, and a return spring 14 is fixed to the surface of the protruding ring 13. One end of the return spring 14 is fixedly connected to the left side of the inner wall of the grip tube 1.

[0032] Through the above technical solution, the protruding ring 13 and the return spring 14 constitute an automatic reset system. When the T-shaped operating handle 7 is released, the elastic potential energy of the return spring 14 pushes the protruding ring 13 to move to the right, thereby driving the connecting rod 8 and the cutting mechanism 2 to automatically reset.

[0033] Multiple support plates 16 are fixed to the inner wall of the grip tube 1, and the surface of the connecting rod 8 slides through the support plates 16.

[0034] Through the above technical solution, the support plates 16 are equidistantly distributed along the axial direction of the gripping tube 1 to form a multi-point guiding system. The central through hole of each support plate 16 forms a sliding pair with the connecting rod 8 to ensure that the connecting rod 8 moves in a straight line.

[0035] A limiting plate 15 is fixed to the inner wall of the holding tube 1, and the limiting plate 15 is located on the right side of the protruding ring 13.

[0036] With the above technical solution, when the return spring 14 pushes the protruding ring 13, the surface of the limiting plate 15 contacts the protruding ring 13, limiting the maximum range of movement of the protruding ring 13 and the connecting rod 8.

[0037] The distance between the bottom of the connecting rod 8 and the top of the mounting frame 4 is greater than the thickness of the frame of the separation filter 11.

[0038] With the above technical solution, when the separating filter 11 is lifted vertically, its frame is kept at a certain distance from the bottom of the connecting rod 8 to avoid interference, so that the separating filter 11 can be taken out and replaced normally.

[0039] Working principle: When the operator holds the grip tube 1, the hand is naturally placed on the T-shaped operating handle 7. When the tangled object to be cut is found, the hand pulls the T-shaped operating handle 7. Guided by the slide groove 6, the connecting rod 8 moves smoothly to the left under the constraint of the support plate 16. The connecting rod 8 drives the support shell 201 to move synchronously. At this time, the movable plate 204 hinged on the support shell 201 rotates under the fulcrum of the connecting frame 203. The extension block 205 converts the rotational motion into the opposite rotation of the front cutting blade 207. The front cutting blade 207 generates the main cutting force during the rotation, cutting long debris such as aquatic plants. The arc-shaped gathering plate 3 continuously guides the floating objects to the retrieval net 5. The intercepted debris is filtered at the separation filter screen 11. After the operation is completed, the T-shaped operating handle 7 is released, and the return spring 14 pushes the protruding ring 13 to the right, completing the working cycle.

[0040] Although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
