Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology, specifically a waterproof drainage pipe for buildings. Background Technology

[0002] Drainage pipes are a type of piping system used to discharge liquids (mainly water). Their purpose is to guide rainwater, domestic sewage, industrial wastewater, etc., from inside or around a building to a suitable discharge point to keep the interior of the building dry and hygienic, while preventing water accumulation from damaging the building foundation and the surrounding environment.

[0003] The existing utility model with authorization announcement number CN220228073U discloses a building drainage pipe. It uses screws to fix an mounting plate to the wall, places the drainage pipe on the surface of a pad, and fits a clamp onto the surface of the drainage pipe, allowing the mounting block to enter the inner cavity of the mounting groove. Turning a knob causes a two-way screw rod to move a slider, which in turn moves a movable plate and a limiting rod, allowing the limiting rod to pass through the limiting groove and fix the mounting block, thereby fixing the clamp. The drainage pipe is then fixed by the pad and the clamp, completing the installation. The operation is convenient; only screws are needed for the initial installation, and subsequent replacements do not require screws.

[0004] While the above technical solution enables quick assembly and disassembly, the water flow rate inside the pipe depends on the amount of water to be drained at the inlet and the inner diameter of the pipe itself. It lacks a rapid flow guiding structure that can adaptively adjust the water flow rate according to the water pressure, which can lead to water accumulation or even leakage when the amount of water to be drained is large.

[0005] Therefore, those skilled in the art have provided a waterproof drainage pipe for buildings to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to provide a waterproof drainage pipe for buildings to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A waterproof drainage pipe for buildings includes a pipe body, and a rapid flow guiding mechanism is provided on the outside of the pipe body;

[0009] The rapid flow guiding mechanism includes two diversion pipes, each of which has a nut sleeve rotatably connected to its outer surface. The outer surface of the main pipe body is fixedly connected to four pressure relief pipes. An annular shell is fixedly connected to the inner wall of the main pipe body. A bracket is fixedly connected to the inner wall of the annular shell. An anti-corrosion bearing is fixedly connected to the inner wall of the bracket. A rotating rod is fixedly connected to the inner ring of the anti-corrosion bearing. An arc-shaped fan blade is fixedly connected to the outer surface of the rotating rod.

[0010] As a further improvement of this utility model: the outer surface of each pressure relief pipe is threaded to the inner wall of the nut cylinder, and two mounting ring plates are fixedly connected to the outer surface of the main pipe body, with three sets of mounting holes opened on the outer surface of each mounting ring plate.

[0011] As a further embodiment of this utility model: two outer waterproof sleeves are fixedly connected to the outer surface of the pipe body, and two inner waterproof sleeves are fixedly connected to the inner wall of the pipe body.

[0012] As a further improvement of this utility model: a first sealing ring is fixedly connected to the outer surface of each pressure relief pipe, and the outer surface of each first sealing ring is in contact with the outer surface of the nut sleeve.

[0013] As a further improvement of this utility model: each of the two ends of each diversion pipe is fixedly connected with a second sealing ring, and the outer surface of each second sealing ring is in contact with the end of the pressure relief pipe away from the main body of the pipe.

[0014] As a further improvement of this utility model: each of the nut cylinders has an anti-slip sleeve fixedly connected to its outer surface, and each of the anti-slip sleeves has several identical anti-slip protrusions fixedly connected to its outer surface.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes the coordinated structure of a main pipe, a branch pipe, a nut sleeve, a pressure relief pipe, an annular shell, a support, an anti-corrosion bearing, a rotating rod, and an arc-shaped fan blade. Wastewater flows down from the top of the main pipe and impacts the arc-shaped fan blade. With the assistance of the rotating rod following the rotation of the inner ring of the anti-corrosion bearing, the arc-shaped fan blade rotates after being impacted by the water flow. This causes centrifugal rotation of the water flow within the main pipe, increasing its velocity. When a large amount of wastewater cannot be discharged quickly enough, it flows back through the lower pressure relief pipe into the branch pipe and then back into the main pipe from the upper pressure relief pipe. This alleviates water pressure while the returning wastewater accelerates the flow, effectively increasing the flow velocity according to water pressure and preventing water accumulation or even seepage. This avoids the problem of water accumulation or seepage caused by the lack of a rapid flow guiding structure that can adaptively adjust the flow velocity according to water pressure, which can lead to the inability to discharge large volumes of wastewater in a timely manner.

[0022] Please see Figure 1-4 A waterproof drainage pipe for buildings includes a pipe body 1. A rapid flow guiding mechanism 2 is provided on the outside of the pipe body 1. The rapid flow guiding mechanism 2 includes two diversion pipes 201. A nut sleeve 202 is rotatably connected to the outer surface of each diversion pipe 201. Two mounting ring plates 3 are fixedly connected to the outer surface of the pipe body 1. Each mounting ring plate 3 has three sets of mounting holes 4 on its outer surface. By setting the mounting holes 4, the mounting ring plate 3 can be fixedly connected to the external docking structure with external bolts or other fastening structures, thereby facilitating the fixed connection of the pipe body 1 with other external pipes or other structures.

[0023] Four pressure relief pipes 203 are fixedly connected to the outer surface of the main pipe body 1. An annular shell 204 is fixedly connected to the inner wall of the main pipe body 1. The outer surface of each pressure relief pipe 203 is threadedly connected to the inner wall of the nut sleeve 202. Two outer waterproof sleeves 5 are fixedly connected to the outer surface of the main pipe body 1, and two inner waterproof sleeves 6 are fixedly connected to the inner wall of the main pipe body 1. By setting the outer waterproof sleeves 5, the waterproof sealing of the outside of the joint when the main pipe body 1 is connected to the external pipe can be increased. By setting the inner waterproof sleeves 6, the waterproof sealing of the inside of the joint when the main pipe body 1 is connected to the external pipe can be increased, thereby jointly increasing the waterproof sealing of the joint when the main pipe body 1 is connected to the external pipe.

[0024] A bracket 205 is fixedly connected to the inner wall of the annular shell 204, and an anti-corrosion bearing 206 is fixedly connected to the inner wall of the bracket 205. A first sealing ring 7 is fixedly connected to the outer surface of each pressure relief pipe 203. The outer surface of each first sealing ring 7 is in contact with the outer surface of the nut cylinder 202. By setting the first sealing ring 7, it can be placed between the pressure relief pipe 203 and the nut cylinder 202, thereby increasing the waterproof sealing and contact wear resistance at the joint.

[0025] The inner ring of the anti-corrosion bearing 206 is fixedly connected to a rotating rod 207. Each end of the diversion pipe 201 is fixedly connected to a second sealing ring 8. The outer surface of each second sealing ring 8 is in contact with the end of the pressure relief pipe 203 away from the main pipe body 1. By setting the second sealing ring 8, it can be placed between the pressure relief pipe 203 and the diversion pipe 201, thereby increasing the waterproof sealing at the joint between the two.

[0026] An arc-shaped fan blade 208 is fixedly connected to the outer surface of the rotating rod 207. An anti-slip sleeve 9 is fixedly connected to the outer surface of each nut cylinder 202. Several identical anti-slip protrusions 10 are fixedly connected to the outer surface of each anti-slip sleeve 9. By setting the anti-slip protrusions 10, the anti-slip property of the outer surface of the anti-slip sleeve 9 can be increased. By setting the anti-slip sleeve 9 and the anti-slip protrusions 10, the anti-slip property of the outer surface of the nut cylinder 202 can be increased together, making it more convenient to turn the nut cylinder 202.

[0027] The working principle of this utility model is as follows: In use, the main pipe body 1 is first connected to an external pipe or other structure. The inner waterproof sleeve 6 can be inserted into the external structure, and the outer waterproof sleeve 5 can wrap around the outside of the external structure. Then, the mounting ring plate 3 is fixed in position using the mounting holes 4 and external fastening bolts, thereby fixing the position of the main pipe body 1. Afterwards, the wastewater to be discharged flows down from the top of the main pipe body 1 and impacts the arc-shaped fan blade 208. With the assistance of the rotating rod 207 following the rotation of the inner ring of the anti-corrosion bearing 206, the arc-shaped fan blade 208 rotates after being impacted by the water flow. This causes the water flow inside the main pipe body 1 to undergo centrifugal rotation and increase the water flow velocity. Meanwhile, a large amount of wastewater that cannot be discharged in time... When the water flows out, it returns through the lower pressure relief pipe 203 into the diversion pipe 201 and then flows into the main body of the pipe 1 through the upper pressure relief pipe 203. This relieves the water pressure, and the returning wastewater also accelerates the water flow in the main body of the pipe 1. When the water flow is small, the rotation speed of the arc-shaped fan blade 208 will also decrease. At the same time, most of the water flow in the main body of the pipe 1 does not flow through the diversion pipe 201. This plays a role in comprehensively increasing the water flow speed according to the water pressure and preventing water accumulation or even seepage. The design of the entire waterproof drainage pipe used in buildings effectively solves the problem of water accumulation or even seepage caused by the lack of a fast flow guiding structure that can adaptively adjust the water flow speed according to the water pressure, which makes it difficult to discharge in time when the drainage volume is large.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
