Description

[0002] Water pollution remains a serious problem due to the indiscriminate discharge of domestic sewage and the dumping of household garbage, especially in urban rivers and rural waterways where floating debris and garbage accumulation are commonplace. This not only affects the aquatic ecosystem but also poses a serious threat to the normal operation of water conservancy projects. For example, garbage accumulation can lead to river blockages, affecting water flow and even triggering secondary disasters such as floods. Therefore, regular cleaning of river debris is an important and necessary task in water conservancy projects.

[0086] Fixed plate 401 is fixedly connected to electric hovercraft 1;

[0087] Cylinder 402 is fixedly connected to the side wall of the fixed plate 401 near the collection frame 2; the cooperation between the fixed plate 401 and the cylinder 402 enables the horizontal movement of the collection frame 4, so that the collection frame 4 moves to a suitable position, ensuring that the garbage is accurately poured into its interior, and reducing the complexity of manual operation.

[0088] L-shaped seat 403 is fixedly connected to the output end of cylinder 402;

[0089] The sleeve rod 404 is fixedly connected to the vertical side wall of the storage frame 4, and the sleeve rod 404 and the L-shaped seat 403 are correspondingly set; the docking design of the L-shaped seat 403 and the sleeve rod 404 is precise, which can quickly complete the installation of the storage frame 4.

[0091] The baffle 406 is slidably connected within the side groove 405;

[0092] Spring 407 is fixedly connected within the side groove 405, and spring 407 is also fixedly connected to the stop bar 406. The operator can remove the storage frame 4 by pressing the stop bar 406, which compresses the spring 407.

[0093] The electric hovercraft 1 is provided with a sliding groove, and the L-shaped seat 403 and the sliding groove are horizontally slidably connected.

[0094] The functional principle of this utility model can be explained through the following operation methods:

[0095] First, the operator places the electric hovercraft 1 on the river channel, turns on the power, and the hovercraft begins to move smoothly on the water.

[0096] The motor 204 is started, driving the lifting screw 202 to rotate, which in turn causes block 205 and block 206 to slide up and down along the sliding opening on the concave plate 201, thereby adjusting the height of the debris collection frame 2 to adapt to different river depths. During the movement of the electric hovercraft 1, garbage and debris on the water surface are collected onto the filter plate 3 inside the debris collection frame 2.

[0097] Floating debris and other contaminants in the river are intercepted on filter plate 3. As the hovercraft moves forward, the debris is gradually collected into the collection frame 2. Once full, the operator can activate motor 3 216 to drive the rotating rod 215 to rotate, causing the collection frame 2 to rotate as a whole and dump the debris into the storage frame 4. Simultaneously, driven by motor 1 204, the collection frame 2, filled with debris, moves vertically upward to the appropriate position.

[0098] In the mounting structure, cylinder 402 pushes L-shaped seat 403 to slide along the slide groove, thereby causing the storage frame 4, which is relatively fixed on L-shaped seat 403, to move horizontally to a suitable position where the collection frame 2 can dump garbage.

[0099] After moving to a suitable position, start motor 208 to drive cross shaft 207 to rotate, which in turn drives insert 209 and transmission plate 210 to rotate synchronously, opening collection frame 2, so that the garbage inside collection frame 2 is tilted and poured into storage frame 4, completing the retrieval and cleaning of floating objects on the water surface.

[0100] When the storage box 4 is full, the operator can press the baffle 406 to retract the baffle 406 into the side groove 405, thereby achieving quick disassembly of the storage box 4 in the vertical direction.

[0101] The entire process is simple to operate and can efficiently clean up debris in the river channel, improving the maintenance efficiency of water conservancy projects.

[0102] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
