Abstract
Description
Technical Field
[0001] This utility model relates to the field of drainage pipe technology, specifically to a hydraulic drainage pipe with a buffer function. Background Technology
[0002] In the field of water conservancy engineering, drainage pipes play an important role in water conveyance, flood discharge, and irrigation, and their performance directly affects the safety and efficiency of the water conservancy system. With the continuous expansion of urban construction and the increasing complexity of water conservancy projects, traditional water conservancy drainage pipes have revealed many problems in dealing with water flow impacts.
[0003] Traditional water conservancy drainage pipes are designed primarily to meet drainage needs, lacking structural buffering measures against water flow impacts. When encountering extreme weather such as heavy rainfall or floods, the water velocity and flow rate inside the drainage pipes increase dramatically. The powerful impact generated instantly can easily cause pipe joints to loosen, crack, or even lead to serious consequences such as local collapse. In addition, due to the lack of buffering structures, high-speed water flow inside the pipes generates significant noise.
[0004] Therefore, developing a water conservancy drainage pipe with buffering function to mitigate water flow impact, reduce noise, extend pipe service life, and achieve effective control of water flow has become an urgent technical problem to be solved in the field of water conservancy engineering. Utility Model Content
[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a hydraulic drainage pipe with buffer function, which can effectively solve the problem that the existing technology lacks buffer measures against water flow impact in its structure.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] This utility model provides a hydraulic drainage pipe with a buffer function, including:
[0008] A drainage pipe, comprising a first pipe and a second pipe with their ends fixedly connected horizontally;
[0009] A buffer assembly includes an annular plate disposed on the outside of a second pipe, the diameter of which is larger than that of the second pipe. Multiple mounting plates are disposed on the inner side of the annular plate, and buffer springs are fixedly connected between the multiple mounting plates and the annular plate.
[0010] According to the above-mentioned hydraulic drainage pipe with buffer function, the drainage pipe is made of silicone material.
[0011] According to the above-mentioned water conservancy drainage pipe with buffer function, the diameter of the second pipe is smaller than the diameter of the first pipe, and the end of the first pipe away from the second pipe is provided with a water inlet.
[0012] According to the above-mentioned hydraulic drainage pipe with buffer function, anti-slip pads are fixedly bonded to the opposite ends of the two buffer springs, and the anti-slip pads are made of elastic material.
[0013] According to the above-mentioned water conservancy drainage pipe with buffer function, when the two buffer springs abut against the pipe body of the second pipe, the buffer springs are in a compressed state, and the buffer springs are never in a state of extreme compression.
[0014] According to the above-mentioned water conservancy drainage pipe with buffer function, the second pipe is fixedly embedded with a foam layer, which is located on the side close to the first pipe.
[0015] The technical solution provided by this utility model has the following advantages compared with the known prior art:
[0016] 1. In this utility model, the diameter of the first pipe is larger than that of the second pipe. When water flows from the large-diameter first pipe into the small-diameter second pipe, according to the momentum theorem, the water flow velocity decreases due to the smaller cross-sectional area of the pipe, and the impact force decreases accordingly. This provides initial buffer protection for the subsequent pipes, reduces the direct impact of the water flow on the pipes, and reduces the risk of damage to the pipes due to water flow impact.
[0017] 2. This utility model uses a buffer spring in the buffer assembly to connect between the annular plate and the mounting plate. When water flows into the pipe, the buffer spring can absorb and buffer the impact force through elastic deformation, preventing the impact force from acting directly on the pipe and protecting the pipe from damage. Moreover, when the buffer spring comes into contact with the second pipe body, it is in a compressed state but has not reached its limit compression. The pre-pressure allows it to respond quickly to the impact of water flow, while ensuring that there is enough buffer space to cope with larger impact forces, ensuring that the buffer assembly works continuously and stably.
[0018] 3. The foam layer fixedly embedded inside the second pipe near the first pipe of this utility model has the characteristics of being lightweight and porous. When water flows through, the foam layer can absorb some of the water flow energy, which can not only buffer the impact of water flow, but also effectively reduce the noise generated by the water flow in the pipe, thus reducing noise pollution to the surrounding environment.
[0019] 4. The drainage pipe of this utility model is made of silicone material. Its good flexibility allows the pipe to buffer the force through its own deformation when subjected to water flow impact or slight external pressure, reducing the risk of breakage. At the same time, the corrosion resistance of silicone ensures that the pipe is not easily corroded when transporting water containing various chemicals for a long time, thus extending the service life of the pipe from the material level.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0027] The present invention will be further described below with reference to the embodiments.
[0028] Example: Refer to Figures 1 to 4 Hydraulic drainage pipes with buffering function include:
[0029] Drainage pipe 1 is made of silicone material. Silicone material has good flexibility and corrosion resistance. The flexibility allows the pipe to buffer some of the force when it is subjected to water flow impact or slight external pressure, reducing the risk of pipe breakage. The corrosion resistance ensures that the pipe will not be easily corroded when transporting water containing various chemicals for a long time, thereby extending the service life of the pipe.
[0030] The drainage pipe 1 includes a first pipe 11 and a second pipe 12 that are horizontally fixedly connected at their ends. A foam layer 121 is fixedly embedded inside the second pipe 12. The foam layer 121 is located on the side close to the first pipe 11. To further enhance the buffering effect, the foam layer 121 is fixedly embedded inside the second pipe 12. The foam layer is lightweight and porous. When water flows through, the foam layer can absorb some of the energy of the water flow, playing a role in buffering and noise reduction, reducing the direct impact of water flow on the pipe, reducing the noise generated by water flow in the pipe, and also reducing the wear of the pipe.
[0031] The diameter of the second pipe 12 is smaller than that of the first pipe 11. An inlet 111 is located at the end of the first pipe 11 furthest from the second pipe 12. This variable diameter design plays a crucial buffering role. When water flows from the larger-diameter first pipe 11 into the smaller-diameter second pipe 12, the water velocity decreases due to the reduced cross-sectional area of the pipes. According to the momentum theorem, the impact force of the water flow also decreases accordingly, thus providing a certain degree of buffering protection for subsequent pipes.
[0032] The buffer assembly 2 includes an annular plate 21 disposed on the outside of the second pipe 12, and the diameter of the annular plate 21 is larger than the diameter of the second pipe 12. Multiple mounting plates 22 are disposed on the inner side of the annular plate 21, and buffer springs 23 are fixedly connected between the multiple mounting plates 22 and the annular plate 21. When water flows and impacts the drainage pipe 1, the buffer springs 23 can absorb and buffer the impact force through their own elastic deformation, so as to prevent the impact force from acting directly on the pipe and thus protect the pipe from damage.
[0033] Anti-slip pads are fixedly bonded to the opposite ends of the two buffer springs 23. The anti-slip pads are made of elastic material. The elastic anti-slip pads can not only increase the friction between the buffer springs and the pipe, so that the buffer springs 23 can play a buffering role more stably, but also further absorb the impact force during the buffering process, thereby improving the buffering performance of the buffer assembly.
[0034] When the two buffer springs 23 come into contact with the pipe body of the second pipe 12, the buffer springs 23 are in a compressed state, and the buffer springs 23 are never in a state of extreme compression. The buffer springs 23 in the compressed state have a certain pre-pressure, which allows them to respond more quickly and play a buffering role when impacted by water flow. The fact that they have not reached the extreme compression state ensures that the buffer springs 23 have enough buffer space, preventing them from losing their buffering effect when subjected to large impact forces, and ensuring that the buffer assembly can work continuously and stably.
[0035] The working principle of this utility model is as follows:
[0036] Water flows into the first pipe 11 from the inlet 111. Due to the variable diameter design of the first pipe 11 and the second pipe 12, the water flow velocity is reduced and the impact force is initially buffered.
[0037] Next, the water flows into the second pipe 12. The foam layer 121 inside the pipe absorbs some of the water flow energy, further reducing the impact and noise. At the same time, when the water flow impact causes the pipe to vibrate or generate lateral force, the buffer spring 23 of the buffer assembly 2 undergoes elastic deformation in the pre-compressed state to absorb the impact force. The anti-slip pad ensures that the buffer spring 23 works stably. In addition, the buffer assembly 2 can also provide external support, share the impact force and prevent the water pipe from shaking, ensuring that the drainage pipe 1 can operate stably and efficiently, effectively mitigating the water flow impact, reducing noise, and extending the service life of the pipe.
[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
