Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of municipal construction engineering, in particular to a drainage pipeline for municipal construction engineering. Background Art
[0002] Urban water supply systems usually use piped water supply, which is the most economical and efficient way of water supply. During the use of pipes, due to factors such as building or road construction, the pipes may leak or break, especially at the bends of the pipes, which are prone to damage. It is usually necessary to protect the bends of the pipes.
[0003] The working principle of traditional drainage pipe protection devices is to fix the outside of the drainage pipe, which cannot effectively reduce the impact force of water flow. When the valve is suddenly closed or opened, or the water pump is suddenly stopped or started, the flow rate will change suddenly, causing pressure fluctuations. When the impact force of the water flow is large, it is easy to produce a water hammer effect, which will still have a large impact on the bends of the drainage pipe, causing ruptures and leakage at the bends inside the drainage pipe. Utility Model Content
[0004] 1. Technical issues to be solved
[0005] In view of the deficiencies in the prior art, the utility model provides a municipal construction engineering drainage pipe, which reduces the pressure of the water flow in the pipe body through a speed limiting component. When the water flows into the curved pipe, since the inner diameter of the curved pipe is larger than the inner diameter of the pipe, the water flow diffuses inside the curved pipe, reducing the water pressure, thereby reducing the impact force of the water flow on the first connecting sleeve, thereby extending the service life of the curved pipe. It solves the problem that when the impact force of the water flow is large, a large impact is generated on the bend of the drainage pipe, which may cause rupture and leakage at the bend inside the drainage pipe.

[0008] The buffer assembly comprises:
[0009] A first connecting pipe, arranged on one side of the pipe body;
[0010] A curved pipe, arranged on one side of the first connecting pipe, the curved pipe being an L-shaped structure;
[0011] A second connecting pipe, fixedly connected to the other side of the curved pipe;
[0012] A second tube body, disposed on the other side of the second connecting tube;
[0013] A first connecting member, disposed at an end of the first connecting pipe;
[0014] A second connecting member, disposed at an end of the second connecting pipe;
[0015] In some embodiments, a plurality of diverter plates are fixedly connected to the interior of the first connecting tube, and the diverter plates are distributed at the middle position and both sides of the interior of the first connecting tube.
[0016] In some embodiments, the first connecting pipe and the second connecting pipe are hollow truncated cone structures, and the inner diameter of the curved pipe is larger than the inner diameter of the pipe body.
[0017] In some embodiments, the diverter plate is a corrugated structure.
[0018] In some embodiments, a plurality of buffer shafts are disposed inside the curved pipe.
[0019] In some embodiments, the outer surface of the buffer shaft is rotatably connected to a roller.
[0020] In some embodiments, a plurality of rolling rings are provided on the outer surface of the drum, and the material of the rolling rings is waterproof rubber.
[0021] In some embodiments, a thread groove is formed on the inner surface of the second connecting pipe.
[0022] (III) Beneficial effects
[0023] Compared with the prior art, the utility model provides a municipal construction engineering drainage pipeline, which has the following beneficial effects:
[0024] 1. The drainage pipe of the municipal construction project has an inner diameter of the curved pipe that is larger than the inner diameter of the first connecting pipe, so that when the high-pressure water flows through the first pipe body, it flows into the curved pipe through the first connecting pipe, and the water flow is depressurized by the inner diameter difference, which has the effect of reducing the impact of the high-pressure water flow on the curved pipe and solves the problem that the curved pipe is easily damaged when the pipe body produces a water hammer effect.
[0025] 2. The drainage pipe of the municipal construction project absorbs the energy of the water flow in the curved pipe through a roller. When the water flows through the roller, the roller rotates accordingly, reducing the impact force while increasing the contact area between the water flow and the roller, which has the effect of absorbing the energy of the water flow and further solves the problem of the curved pipe being easily damaged due to the water hammer effect on the pipe body.

[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0034] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.
[0035] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0036] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by this application. The working principle of the traditional drainage pipe protection device is to fix the outside of the drainage pipe, and no buffer component is set inside.
[0037] In the related technology, when the valve is suddenly closed or opened, or the water pump is suddenly stopped or started, the flow rate will change suddenly, causing pressure fluctuations. When the impact force of the water flow is large, it is easy to produce a water hammer effect, which will still have a large impact on the bends of the drainage pipe, causing the bends inside the drainage pipe to rupture and leak.
[0038] In order to solve the problems in the related technology to a certain extent, an embodiment of the present application provides a drainage pipe for a municipal construction project. When it is needed, the inner diameter of the curved pipe is larger than the inner diameter of the first connecting pipe, so that when the high-pressure water flows through the first pipe body, it flows into the curved pipe through the first connecting pipe, and the water flow is depressurized by the inner diameter difference, which has the effect of reducing the impact of the high-pressure water flow on the curved pipe, and solves the problem that the curved pipe is easily damaged when the water hammer effect occurs in the pipe body.
[0039] The present application is described below with reference to the accompanying drawings and specific embodiments:
[0040] Combination Figure 1-Figure 4 The embodiment of the present application provides a municipal construction engineering drainage pipe including a pipe body 1, a buffer assembly 2 arranged on one side of the pipe body 1, the buffer assembly 2 includes a first connecting pipe 21 arranged on one side of the pipe body 1, a curved pipe 22 arranged on one side of the first connecting pipe 21, the curved pipe 22 is an L-shaped structure, a second connecting pipe 23 is fixedly connected to the other side of the curved pipe 22, a second pipe body 24 is arranged on the other side of the second connecting pipe 23, a first connecting piece 25 is arranged at the end of the first connecting pipe 21, and a second connecting piece 26 is arranged at the end of the second connecting pipe 23.
[0041] Because the inner diameter of the curved pipe 22 is larger than the inner diameter of the first connecting pipe 21, the water flows into the curved pipe 22 through the first connecting pipe 21, and the pressure of the water flow is released by the inner diameter difference, which has the effect of reducing the impact of the high-pressure water flow on the curved pipe 22, and solves the problem that the curved pipe 22 is easily damaged when the pipe body 1 produces a water hammer effect.
[0042] In some embodiments, a plurality of diverter plates 27 are fixedly connected to the interior of the first connecting tube 21 , and the diverter plates 27 are distributed at the middle position and both sides of the interior of the first connecting tube 21 .
[0043] The diverter plate 27 has a diverting and buffering effect. When water flows through the surface of the diverter plate 27, the water will flow to both sides of the diverter plate 27 and generate friction with the surface of the diverter plate 27, thereby reducing the impact force of the water flow and absorbing the energy generated by the water flow, thereby protecting the curved pipe 22 to a certain extent.
[0044] In some embodiments, the first connecting pipe 21 and the second connecting pipe 23 are hollow truncated cone structures, and the inner diameter of the curved pipe 22 is larger than the inner diameter of the pipe body 1 .
[0045] The truncated cone structure of the first connecting pipe 21 can ensure that the water flows in all directions when flowing from the pipe body into the curved pipe 22. The first connecting pipe 21 can make the water flow into the curved pipe 22 more slowly, and the inner diameter difference can help the water flow to release pressure.
[0046] In some embodiments, the diverter plate 27 is a corrugated structure.
[0047] The corrugated structure of the diverter plate 27 further increases the contact area between the water flow and the diverter plate 27, thereby absorbing the energy of the flowing water to the greatest extent and reducing the water hammer effect.
[0048] In some embodiments, a plurality of buffer shafts 28 are disposed inside the curved pipe 22 .
[0049] The buffer shaft 28 is used to further prevent the curved pipe 22 from being impacted by water at its bend, so that the impact force of the water flow is dispersed on the buffer shaft 28 , thereby absorbing the energy of the water flow and alleviating the impact of the water flow on the curved pipe 22 .
[0050] In some embodiments, a roller 29 is rotatably connected to the outer surface of the buffer shaft 28 .
[0051] The roller 29 allows the water flow to roll on the surface of the roller 29 , so that the water flow forms a vortex around the roller 29 , thereby absorbing the energy of the water flow and further improving the service life of the curved pipe 22 .
[0052] In some embodiments, a plurality of roller rings 210 are sleeved on the outer surface of the drum 29 , and the roller rings 210 are made of waterproof rubber.
[0053] The rolling ring 210 can make the water flow stay more on the surface of the drum 29, so that a part of the water flow rubs against the drum 29 between the rolling rings 210, further consuming the energy of the water flow and improving the buffering efficiency.
[0054] In some embodiments, a thread groove 211 is formed on the inner surface of the second connecting pipe 23 .
[0055] The thread groove 211 inside the second connecting pipe 23 can make the water flow more smoothly when entering the second pipe body, forming a vortex inside the second connecting pipe 23 to increase the water flow speed.
[0056] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example" or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification.
[0057] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.
