[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. Water is an indispensable and precious resource for human production and life. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging disasters, and regulate and distribute water to meet the people's needs for water resources in life and production.

[0003] As an important component of water conservancy projects, pipes play the role of transporting and connecting water bodies. However, when river sediment, silt and various garbage in the river pass through the pipes, they are prone to blockage. Over time, the blockage becomes more and more serious, making it impossible for water to pass through the pipes. In the existing technology, long poles are often used to push the garbage in the pipes to unclog the pipes, but this method is time-consuming and labor-intensive, and it is difficult to clean the pipes. Some branches and large pieces of garbage are still stuck in the pipes, causing the pipes to be blocked again more easily. Utility Model Content

[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0023] See also Figures 1-4 A silt removal and dredging device for water conservancy construction includes: a follow-up cylinder 1, the front end of the follow-up cylinder 1 is fixedly connected to a connecting pipe 3, a motor 8 is installed in the connecting pipe 3, the output shaft of the motor 8 passes through the connecting pipe 3 and is fixedly connected to a drill bit 2, a plurality of nozzles 4 are distributed in an array on one end of the follow-up cylinder 1 near the connecting pipe 3, a water passage 12 is opened in the follow-up cylinder 1, the water passage 12 is connected to the plurality of nozzles 4, and a water inlet 11 connected to the water passage 12 is provided on the tail of the follow-up cylinder 1.

[0024] Specifically, the utility model utilizes a rotating drill bit 2 to drill a hole at the location of the blockage, and pushes the follow-up tube 1 so that the follow-up tube 1 penetrates deep into the blocked pipe. The four nozzles 4 flush the inner wall of the hole, reducing the thickness of the blockage layer and disintegrating the blockage layer at the same time, which not only speeds up the cleaning efficiency but also achieves a thorough cleaning of the blockage layer in the pipe.

[0025] Furthermore, a threaded groove 13 communicating with the water passage 12 is provided in the follow-up cylinder 1 , and a one-way valve 14 is fixedly installed in the water passage 12 . The one-way valve 14 is located between the water inlet 11 and the threaded groove 13 .

[0026] Specifically, refer to Figure 3 By opening a threaded groove 13 at the tail end of the follow-up tube 1, it can be used to connect the next section of the follow-up tube 1, which is suitable for cleaning longer pipes. The water flow direction of the one-way valve 14 is from right to left. When multiple follow-up tubes 1 are used, it can be ensured that there is only one water inlet and outlet on the multiple sections of the follow-up tube 1, and when the two sections of the follow-up tube 1 are threadedly connected, a suitable sealing ring needs to be assembled to prevent water leakage.

[0027] Furthermore, a pad 31 is provided between the drill bit 2 and the connecting tube 3 . Four rotatably arranged first expansion bars 5 are arranged in an array on the side of the pad 31 close to the connecting tube 3 . The first expansion bars 5 are connected to the pad 31 via a torsion spring 7 .

[0028] Specifically, the output shaft of the motor 8 passes through the outer wall of the connecting tube 3 and the pad 31 and is fixedly connected to the drill bit 2. The first expansion strip 5 is rotated and arranged on the side of the pad 31 close to the connecting tube 3. When the torque force of the torsion spring 7 is overcome and the side surfaces of the four first expansion strips 5 are pressed against the outer wall of the connecting tube 3, the maximum outer diameter formed by the four first expansion strips 5 is smaller than the maximum outer diameter of the drill bit 2, that is, the hole opened by the drill bit 2 can pass through the four first expansion strips 5. After the drill bit 2 carries the connecting tube 3 through the blocked position, under the action of the torque force of the torsion spring 7, the four first expansion strips 5 are rotated to the radial direction of the connecting tube 3 under the blocking action of the pad 31, and finally the follow-up tube 1 is pulled back, and the four first expansion strips 5 are used to bring out the blocked layer in the pipe, which greatly speeds up the speed of cleaning the pipeline.

[0029] Furthermore, it also includes a rotating shaft 311, the first expansion strip 5 is fixedly sleeved on the outside of the rotating shaft 311, the rotating shaft 311 is rotatably set on the base plate 31, the torsion spring 7 is movably sleeved on the outside of the rotating shaft 311, one end of the torsion spring 7 is inserted into the base plate 31, and the other end of the torsion spring 7 is inserted into the first expansion strip 5. Under the action of the torque force of the torsion spring 7, the four first expansion strips 5 are pushed against the side of the base plate 31.

[0030] Furthermore, the top of the first expansion bar 5 is threadedly connected to the second expansion bar 6, the four first expansion bars 5 are connected by a first chain net 51, and the four second expansion bars 6 are connected by a second chain net 61. The first chain net 51 and the second chain net 61 are staggered.

[0031] Specifically, by threading the second expansion strip 6 at the top end of the first expansion strip 5, the total length of the first expansion strip 5 and the second expansion strip 6 can be changed by rotating the second expansion strip 6, thereby achieving adaptation to pipes of different diameters. By setting the first iron chain net 51 and the second iron chain net 61, the interception capabilities of the first expansion strip 5 and the second expansion strip 6 are greatly improved, and the cleaning effect is improved. The first iron chain net 51 and the second iron chain net 61 are staggered. When the total length of the first expansion strip 5 and the second expansion strip 6 is changed, the overlapping part of the first iron chain net 51 and the second iron chain net 61 can be used to make up for the newly appeared gap between the first expansion strip 5 and the second expansion strip 6.

[0032] In this utility model, reference is made to Figures 1 to 4First, rotate the first expansion strip 5 according to the diameter of the pipe so that the total length of the first expansion strip 5 and the second expansion strip 6 can be adapted. Then connect the external pressure water pipe to the water inlet 11, start the motor 8, and the drill bit 2 opens a hole in the blockage layer in the pipe. As the drill bit 2 goes deeper, the four first expansion strips 5 overcome the torque of the torsion spring 7 and enter the drilled hole. Use hydraulic equipment to push the device to speed up the excavation speed of the drill bit 2. At the same time, the four nozzles flush the opened inner wall until the drill bit 2 drives the connecting pipe 3 to pass through the blockage layer. Under the action of the torque of the torsion spring 7, the four first expansion strips 5 are expanded. Finally, use hydraulic equipment to pull the device back, and the first chain net 51 and the second chain net 61 pull out the blockage layer as a whole, so that the pipe is unobstructed.

[0033] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
