Description

Technical Field

[0001] This utility model relates to the field of water conservancy pipeline technology, specifically to a suction pipe for water conservancy dredging equipment. Background Technology

[0002] Water conservancy projects require the construction of various types of hydraulic structures, such as dams, dikes, spillways, sluice gates, intakes, canals, raft channels, and fish passages. During the construction of water conservancy projects, it is necessary to clean underwater silt. Usually, dredging equipment is used in conjunction with suction pipes to clean underwater silt.

[0003] When using existing suction pipes, the presence of stones mixed in with the sludge can easily damage the pipes, and the overall strength is low, making them inconvenient to use. Utility Model Content

[0004] The purpose of this utility model is to provide a suction pipe for water conservancy dredging equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a suction pipe for a water conservancy dredging device, comprising a pipe body, an inlet, a channel, an outlet, and an impact-resistant fiber mesh. An inlet is provided on one side of the inside of the pipe body, a channel is provided in the middle of the inside of the pipe body, an outlet is provided on the other side of the inside of the pipe body, and impact-resistant fiber mesh is connected to both ends of the inner wall of the pipe body.

[0006] Preferably, the tube body includes a wear-resistant protective layer, a reinforcing layer, and an anti-adhesion layer. The inner side of the wear-resistant protective layer is connected to the reinforcing layer, the inner side of the reinforcing layer is connected to the anti-adhesion layer, and both ends of the inner side of the anti-adhesion layer are connected to an impact-resistant fiber mesh.

[0007] Preferably, the thickness of the tube gradually decreases from both ends to the middle.

[0008] Preferably, the internal space of the entrance, passage, and exit changes from wide to narrow, and then from narrow to wide.

[0009] Preferably, the surface of the impact-resistant fiber mesh has a perforated grid, and the shape of the impact-resistant fiber mesh is adapted to the shape of the inlet and outlet.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] By incorporating a pipe body, a wear-resistant protective layer protects the pipeline from external physical impacts and environmental corrosion, while also providing a degree of flexibility. The reinforcing layer offers high strength and compressive strength, adapting to high-load dredging operations. The anti-adhesion layer reduces friction and adhesion between silt and the pipe wall, lowering the likelihood of blockages and improving conveying efficiency. The thickened pipe walls at both ends prevent damage from stones and other hard objects during silt entry and exit. Impact-resistant fiber mesh is embedded at the inlet and outlet ends of the inner wall of the pipe, protecting these locations and preventing impacts from stones during entry and exit that could cause pipe breakage.

[0018] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0019] Please see Figures 1-5 This utility model provides a suction pipe for a water conservancy dredging device, including a pipe body 1, an inlet 2, a channel 3, an outlet 4, and an impact-resistant fiber mesh 5. The inlet 2 is provided on one side of the inside of the pipe body 1, the channel 3 is provided in the middle of the inside of the pipe body 1, and the outlet 4 is provided on the other side of the inside of the pipe body 1. The internal space of the inlet 2, the channel 3, and the outlet 4 changes from wide to narrow, and then from narrow to wide. The sludge flows into the channel 3 from the inlet 2 and then flows out from the outlet 4. The impact-resistant fiber mesh 5 is embedded at both ends of the inner wall of the pipe body 1, namely the inlet 2 and the outlet 4. The surface of the impact-resistant fiber mesh 5 has a hollow mesh, and the shape of the impact-resistant fiber mesh 5 is adapted to the shape of the inlet 2 and the outlet 4, which facilitates the installation of the impact-resistant fiber mesh 5.

[0020] The tube body 1 includes a wear-resistant protective layer 11, a reinforcing layer 12, and an anti-adhesion layer 13. The inner side of the wear-resistant protective layer 11 is connected to the reinforcing layer 12. The wear-resistant protective layer 11 is made of high wear-resistant polyurethane or modified rubber material, which has excellent wear resistance, tear resistance, and UV resistance. The reinforcing layer 12 is made of aramid fiber woven mesh or carbon fiber reinforced composite material, which has a spiral winding structure. The inner side of the reinforcing layer 12 is connected to the anti-adhesion layer 13. The anti-adhesion layer 13 is made of Teflon coating or nano-silicone resin coating, with an ultra-smooth surface and a low coefficient of friction. Both ends of the inner side of the anti-adhesion layer 13 are connected to impact-resistant fiber mesh 5.

[0021] The thickness of the pipe body 1 gradually decreases from both ends to the middle. The thickened pipe walls at both ends can prevent hard objects such as stones from damaging the pipe body 1 when silt enters or exits.

[0022] Specifically, the suction pipe is first connected to the equipment. Sludge can enter the channel from inlet 2 and flow out from outlet 4. The impact-resistant fiber mesh 5 can protect the inlet 2 and outlet 4 to prevent stones from impacting the pipe body 1 and causing it to break when entering and exiting. The wear-resistant protective layer 11 can protect the pipeline from external physical impact and environmental corrosion, while providing a certain degree of flexibility. The reinforcing layer 12 can provide high strength and compressive strength to adapt to high-load dredging operations. The anti-adhesion layer 13 can reduce the friction and adhesion between mud and sand and the pipe wall, reduce the probability of blockage, and improve the conveying efficiency.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
