Description

Technical Field

[0001] The utility model relates to the technical field of house building drainage, and more specifically, to a pipe buffer device for house drainage. Background Art

[0002] In the main drainage pipes of high-rise buildings, the water flows from top to bottom. The kinetic energy generated by the water flow in the drainage pipes causes a greater impact on the pipes on the bottom floor.

[0003] In the prior art, the main drainage channels used between the floors are all equipped with circular elbows for guidance, and the circular elbows have the function of slowing down the downward impact of the water flow in the pipes. However, the main function of the circular elbows is to provide guidance for the water flow in the pipes. When the water flows through the circular elbows, the flow state of the water flow will change greatly, thereby slowing down the impact of the water flow in the pipes, but the mitigation effect is poor.

[0004] Therefore, the existing demand is not met, and we have proposed a pipe buffer device for house drainage. Utility Model Content

[0005] The purpose of the utility model is to provide a pipe buffer device for house drainage, so as to solve the problem that in the prior art, an annular elbow for guidance is installed on the main drainage channel used between each floor, and the annular elbow has the function of slowing down the downward impact of water flow in the pipe, but the main function of the annular elbow is to provide guidance for the water flow in the water pipe. When the water flows through the annular elbow, the flow state of the water flow will change greatly, thereby achieving the purpose of slowing down the impact of the water flow in the pipe, but the slowing effect is poor.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: a pipe buffer device for house drainage, comprising: a corner pipe; two connecting pipes, the two connecting pipes are arranged on the corner pipe at intervals, and the ends of the two connecting pipes away from the corner pipe are respectively connected to the downpipe and the outlet pipe; a buffer assembly, the buffer assembly is arranged in the corner pipe; the buffer group includes a rotating shaft, a plurality of blades are arranged on the curved surface of the rotating shaft, and each of the blades is provided with a plurality of through holes.

[0007] By adopting the above technical solution, firstly, the corner tube in the existing technology itself has a certain impact reduction effect. Secondly, due to the impact reduction effect of the corner tube itself, it is difficult to meet the needs of the main drainage pipe system of high-rise buildings. In order to improve the stability of the corner tube, a buffer component for reducing impact is installed in the corner tube to prevent the corner tube from wearing too quickly, causing the corner tube to rupture or leak. Finally, a number of blades and a rotating shaft are provided in the buffer component. The blades are used to reduce the impact of water flow, block the water flow, and prevent the water flow from directly forming a straight line to impact the corner tube, thereby accelerating the wear of the corner tube. If the water flow can push the blades to rotate the rotating shaft, the water flow passes through the through hole, further disrupting the water flow in the corner tube, directly further increasing the size of the vortex or backflow, and improving the water flow reduction effect.

[0008] The present invention is further configured as follows: the corner tube includes a housing portion, the housing portion is in a round pancake shape, a buffer assembly is provided in the housing portion, and a pair of connecting portions for connecting the connecting tube and the housing portion are provided at intervals on the curved surface of the housing portion.

[0009] By adopting the above technical solution, the corner tube is used to improve the water flow slowing effect. Compared with the traditional corner tube, the corner tube in this solution not only has the water flow effect, but also further improves the water flow slowing effect of the corner tube. The shape of the bending part of the corner tube is changed to a round pancake shape to increase the size and probability of vortex or backflow.

[0010] The utility model is further configured as follows: the plurality of through holes provided on each of the blades are arranged in a rectangular array.

[0011] By adopting the above technical solution, the effect of disturbing the water flow in the corner tube is improved, and the effect of reducing the water flow velocity is prevented from being reduced due to the irregular positions of the through holes on the blades.

[0012] The utility model is further configured as follows: an elastic plate is provided in the accommodating portion.

[0013] By adopting the above technical solution, the elastic plate can be used to protect the inner wall of the corner tube, reduce the impact force of water flow on the corner tube, and reduce the wear of the corner tube.

[0014] The utility model is further configured as follows: a notch is provided at one end of each blade away from the rotating shaft.

[0015] By adopting the above technical solution, the elastic plate is prevented from blocking the blade from rotating around the rotating shaft when each blade passes through the elastic plate. If the connection between the blade and the elastic plate is loose, the blade and the elastic plate have a mutual limiting effect.

[0016] The utility model is further configured as follows: a plurality of blades are arranged on the rotating shaft in a circular array.

[0017] By adopting the above technical solution and utilizing the arrangement positions of several blades, the disrupting effect of the water flow is improved, uneven water flow is prevented, and the flow velocity of the water flow in the corner tube is further increased, as well as the effect of vortex or backflow is enhanced.

[0018] The utility model is further configured such that the angle between any two adjacent blades is 30°.

[0019] By adopting the above technical solution, the disturbing effect of water flow is improved.

[0020] The present invention is further configured as follows: protective covers are provided on both sides of the accommodating portion, and the protective covers are located on two adjacent sides of the curved surface of the accommodating portion.

[0021] By adopting the above technical solution, the rigidity of the accommodating portion is improved and the corner tube is protected.

[0022] The utility model is further configured as follows: a plurality of ribs are provided on the curved surface of the accommodating portion.

[0023] By adopting the above technical solution, the rigidity of the accommodating portion is improved.

[0024] To sum up, the utility model has the following beneficial effects: first, the corner tube in the prior art itself has a certain impact reduction effect. Secondly, due to the impact reduction effect of the corner tube itself, it is difficult to meet the needs of the main drainage pipe system of high-rise buildings. In order to improve the stability of the corner tube, a buffer component for reducing impact is installed in the corner tube to prevent the corner tube from wearing too quickly, causing the corner tube to rupture or leak. Finally, a number of blades and a rotating shaft are provided in the buffer component. The blades are used to reduce the impact of water flow, block the water flow, prevent the water flow from directly forming a straight line impact, and accelerate the wear of the corner tube. If the water flow can push the blades to rotate the rotating shaft, it can further disrupt the water flow in the corner tube, directly further increase the size of the vortex or backflow, and improve the water flow reduction effect.

[0037] The following is combined with Figure 1-4 The utility model is described in further detail.

[0038] Example 1

[0039] like Figures 1-4 As shown, a pipe buffer device for house drainage includes a corner pipe 1, a connecting pipe 2 and a buffer assembly.

[0040] Two connecting pipes 2 are arranged on the corner pipe 1 at intervals, and the angle between the two connecting pipes 2 is 90°. The ends of the two connecting pipes 2 away from the corner pipe 1 are respectively connected to the downpipe and the outlet pipe, and the corner pipe 1, the connecting pipe 2, the downpipe and the outlet pipe are connected to each other.

[0041] The buffer assembly is arranged in the corner tube 1.

[0042] The corner tube 1 includes a housing portion 12, which is in the shape of a pancake. A buffer component is provided in the housing portion 12. A pair of connecting portions 11 for connecting the connecting pipe 2 and the housing portion 12 are provided on the curved surface of the housing portion 12 at intervals, and the angle between the two connecting portions 11 is 90°. The shape of the housing portion 12 is utilized to maximize the use of vortex and backflow phenomena, thereby increasing the resistance of the water flow. In addition, when vortex and backflow occur, the pressure brought to the corner tube 1 by the water flow through the corner tube 1 is reduced, thereby improving the overall stability of the pipeline system.

[0043] The corner tube 1 has a shell and can be installed on a wall or welded to an existing iron frame using angle iron.

[0044] An elastic plate 6 is provided in the accommodating portion 12, and the elastic plate 6 is located below the downpipe. The elastic plate 6 will deform under pressure, but the elastic plate 6 also has resilience. If the water flow in the downpipe flows into the corner pipe 1, it can directly fall on the elastic plate 6 without any obstruction.

[0045] The buffer assembly includes a rotating shaft 7 rotatably disposed in the accommodating portion 12 , and the rotating shaft 7 is located above the elastic plate 6 , and a buffer group is provided on the curved surface of the rotating shaft 7 .

[0046] The rotating shaft 7 is a damping rotating shaft.

[0047] The buffer group includes a plurality of blades 5 for buffering, and the plurality of blades 5 are arranged in a circular array on the rotating shaft 7. Each of the blades 5 is provided with a plurality of through holes 51. The through holes 51 have the effect of reducing the direct impact force of the water flow on the blade 5, and can disrupt the water flow to prevent the linear impact of the water flow. The blade 5 corresponds to the position of the water pipe. The water flow falling from the upper water pipe can push the blade 5 to rotate the rotating shaft 7. If the blade 5 rotates through the elastic plate 6, there is a gap between the blade 5 and the elastic plate 6, and the gap size is 1mm-0.5mm.

[0048] Preferably, in order to facilitate the cleaning of the blades 5 later, the plurality of through holes 51 provided on each blade 5 are arranged in a rectangular array, and the angle between any two adjacent blades 5 is 30°.

[0049] A protective cover 3 is provided on both sides of the accommodating portion 12, and the protective cover 3 is located on two adjacent surfaces of the curved surface of the accommodating portion 12. The protective cover 3 is used to protect the accommodating portion 12 and improve the rigidity of the accommodating portion 12, thereby preventing the accommodating portion 12 from being deformed due to a decrease in fatigue strength due to long-term use.

[0050] A plurality of ribs 4 are provided on the curved surface of the accommodation portion 12 to prevent the accommodation portion 12 from being deformed due to a reduction in fatigue strength caused by long-term use.

[0051] Example 2

[0052] The difference between Example 2 and Example 1 is that:

[0053] A notch 52 is provided at one end of each blade 5 away from the rotating shaft 7 to prevent the elastic plate 6 from blocking the blade 5 from rotating around the rotating shaft 7 when each blade 5 passes through the elastic plate 6. If the connection between the blade 5 and the elastic plate 6 is loose, the blade 5 and the elastic plate 6 have a mutual limiting effect. If the blade 5 rotates and passes through the elastic plate 6, a gap will exist between the blade 5 and the elastic plate 6, and the gap size is 1mm-0.5mm.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
