A sewer pipe

Abstract

This utility model relates to the field of intercepting sewage pipe technology and discloses an intercepting sewage pipe, which includes a pipe body, a box fixedly installed on the surface of the pipe body, a support plate provided on the outer side of the box, a telescopic cylinder fixedly installed on the surface of the support plate, a filter screen provided inside the box, a cleaning mechanism provided inside the box, and a facilitating mechanism provided inside the box. In this intercepting sewage pipe, the telescopic cylinder, when activated, drives the cleaning plate on the movable rod to clean the surface of the filter screen, improving the subsequent sewage discharge effect of the pipe and preventing blockage. Simultaneously, the guide rods on the cleaning plate work together to obstruct some fixed impurities in the sewage, preventing damage to the surface of the filter screen. At the same time, the swing plate, impacted by fixed impurities with the water flow, can deflect on the surface of the straight rod, causing the torsion spring to deform. During the torsion spring's return process, the impurities are guided outwards, protecting the surface of the filter screen and ensuring the subsequent discharge effect of the filter screen.

Description

Technical Field

[0001] This utility model relates to the field of intercepting sewage pipe technology, specifically to an intercepting sewage pipe. Background Technology

[0002] Interception sewers are a water pollution treatment project that involves constructing and upgrading the sewage pipes inside sewage-generating units located on both sides of a river, connecting them to the sewage pipe system laid under urban roads, and then transferring the sewage to urban sewage treatment plants for centralized treatment.

[0003] According to a public notice regarding a sewage interception and collection pipe for pipeline renovation (Announcement No.: CN219450980U), in the aforementioned application, after sewage enters the inlet pipe, it passes through the first through hole and then enters the interior of the tank. Through the installation of the second filter screen, the sewage passes through the second filter screen and the first filter screen in sequence for double filtration. Larger garbage is first filtered and blocked by the second filter screen.

[0004] However, in actual use, impurities in the wastewater adhere to the surface of the filter screen after being filtered by the filtration structure, making it difficult to clean the main body of the pipe and the filtration structure. This affects the flow rate of subsequent wastewater discharged through the intercepting and collecting pipe, and in severe cases, may cause blockage of the intercepting and collecting pipe. In view of this, we propose an intercepting pipe. Utility Model Content

[0005] The purpose of this utility model is to provide a sewage interception pipe to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sewage interception pipe, comprising a pipe body, a housing fixedly mounted on the surface of the pipe body, a support plate provided on the outer side of the housing, a telescopic cylinder fixedly mounted on the surface of the support plate, a filter screen provided inside the housing, a cleaning mechanism provided inside the housing, and a promoting mechanism provided inside the housing. The cleaning mechanism includes:

[0007] A movable rod is fixedly installed at the movable end of a telescopic cylinder. A cleaning plate is fixedly installed on the arc surface of the movable rod. A guide hole is provided on the surface of the cleaning plate. A guide rod is fixedly installed inside the housing. A movable groove is provided on the surface of the cleaning plate.

[0008] A straight rod is fixedly installed on the inner wall of the movable groove. A torsion spring is fixedly connected to the arc surface of the straight rod. A swing plate is fixedly connected to the end of the torsion spring away from the arc surface of the straight rod. A limiting rod is fixedly installed on the inner wall of the movable groove.

[0009] Preferably, the promoting mechanism includes an arc-shaped plate, which is fixedly installed on the surface of the swing plate. A circular groove is formed on the end surface of the arc-shaped plate, and a roller is movably installed on the inner wall of the circular groove. A protrusion is fixedly installed on the arc surface of the roller.

[0010] Preferably, the protrusions are spherical in shape, and there are several protrusions arranged in a circular array and fixedly installed on the arc surface of the roller. The protrusions rotate with the roller and squeeze the surface of the filter screen.

[0011] Preferably, the swing plate is fork-shaped, and a rotating hole is formed on the surface of the swing plate. The diameter of the rotating hole is adapted to the diameter of the straight rod. The swing plate is sleeved on the arc surface of the straight rod, and the swing plate can deflect on the arc surface of the straight rod.

[0012] Preferably, the diameter of the guide rod is adapted to the diameter of the guide hole, and the guide rod passes through the cleaning plate, so that the cleaning plate can move on the arc surface of the guide rod while ensuring the stability of the cleaning plate.

[0013] Preferably, the shape of the movable groove is adapted to the shape of the straight rod and the limiting rod, so that the limiting rod and the straight rod can be installed on the surface of the movable groove to ensure stability.

[0014] Compared with the prior art, the present invention provides a sewage interception pipe, which has the following beneficial effects:

[0015] 1. This intercepting pipe is equipped with a cleaning mechanism. The telescopic cylinder drives the cleaning plate on the movable rod to clean the surface of the filter screen, improving the sewage discharge effect of the subsequent pipe and preventing blockage. At the same time, the guide rod on the cleaning plate works together to obstruct some fixed impurities in the sewage, preventing damage to the surface of the filter screen. Meanwhile, the swing plate is impacted by fixed impurities with the water flow, and it can deflect on the surface of the straight rod. During the torsion spring deformation and the torsion spring reset process, the impurities are guided to the outside, protecting the surface of the filter screen and ensuring the discharge effect of the subsequent filter screen.

[0016] 2. This intercepting pipe is equipped with a facilitating mechanism. During the swinging process of the swing plate, the arc plate causes the roller to move in contact with the filter screen. At the same time, the movable groove, together with the limiting rod, restricts the swinging angle of the swing plate, so that the protrusions on the roller vibrate and squeeze the surface of the filter screen, making the mesh of the filter screen larger and promoting the falling of impurities, thus ensuring the discharge effect of the filter screen.

[0023] like Figures 1-5 As shown, this utility model provides a technical solution: a sewage intercepting pipe, including a pipe body 1, a box body 2 fixedly installed on the surface of the pipe body 1, a support plate 5 provided on the outer side of the box body 2, a telescopic cylinder 6 fixedly installed on the surface of the support plate 5, a filter screen 7 provided inside the box body 2, a cleaning mechanism 3 provided inside the box body 2, and a promoting mechanism 4 provided inside the box body 2. The cleaning mechanism 3 includes a movable rod 301, a cleaning plate 302, a guide rod 303, a guide hole 304, a movable groove 305, a straight rod 306, a torsion spring 307, a limiting rod 308, and a swing plate 309.

[0024] In one embodiment of this utility model, the movable rod 301 is fixedly installed at the movable end of the telescopic cylinder 6, the arc surface of the movable rod 301 is fixedly installed with the cleaning plate 302, the surface of the cleaning plate 302 is provided with the guide hole 304, the inside of the housing 2 is fixedly installed with the guide rod 303, the surface of the cleaning plate 302 is provided with the movable groove 305, the straight rod 306 is fixedly installed on the inner wall of the movable groove 305, the arc surface of the straight rod 306 is fixedly connected with the torsion spring 307, the end of the torsion spring 307 away from the arc surface of the straight rod 306 is fixedly connected with the swing plate 309, and the inner wall of the movable groove 305 is fixedly installed with the limiting rod 308.

[0025] In addition, the promoting mechanism 4 includes an arc plate 401, which is fixedly installed on the surface of the swing plate 309. A circular groove 402 is provided on the end surface of the arc plate 401. A roller 403 is movably installed on the inner wall of the circular groove 402. A protrusion 404 is fixedly installed on the arc surface of the roller 403. The protrusion 404 is spherical in shape and there are several protrusions 404. The several protrusions 404 are fixedly installed on the arc surface of the roller 403 in a circumferential array. The protrusions 404 rotate with the roller 403 and squeeze the surface of the filter screen 7.

[0026] In this embodiment of the invention, the swing plate 309 is fork-shaped, and a rotating hole is formed on its surface. The diameter of the rotating hole is adapted to the diameter of the straight rod 306. The swing plate 309 is fitted onto the arc surface of the straight rod 306, allowing it to deflect on the arc surface. The diameter of the guide rod 303 is adapted to the diameter of the guide hole 304, and the guide rod 303 passes through the cleaning plate 302, enabling the cleaning plate 302 to move on the arc surface of the guide rod 303 while ensuring its stability. The shape of the movable groove 305 is consistent with that of the straight rod 306 and the limiting rod 308. The shapes are adapted to each other so that the limiting rod 308 and the straight rod 306 can be installed on the surface of the movable groove 305 to ensure stability. The cleaning plate 302 is provided with corresponding bristles on the side near the filter screen 7 to clean the surface of the filter screen 7. Several cleaning plates 302 are provided, and several cleaning plates 302 are fixedly installed on the arc surface of the movable rod 301 in a linear array. The swing plates 309 of adjacent cleaning plates 302 are arranged in a cross pattern to facilitate the rebound and removal of impurities from the fixed body and protect the surface of the filter screen 7. The upper surface of the box 2 is detachably connected to facilitate opening and cleaning of the internal impurities.

[0027] In this utility model, during use, the telescopic cylinder 6 is activated to drive the cleaning plate 302 on the movable rod 301 to clean the surface of the filter screen 7, thereby improving the sewage discharge effect of the subsequent pipe body 1 and preventing blockage. At the same time, the guide rod 303 on the cleaning plate 302 works together to obstruct some fixed impurities in the sewage, preventing damage to the surface of the filter screen 7. Meanwhile, the swing plate 309 is impacted by fixed impurities with the water flow and can deflect on the surface of the straight rod 306, causing the torsion spring 307 to deform. During the reset process of the torsion spring 307, the impurities are guided to the outside, protecting the surface of the filter screen 7 and ensuring the discharge effect of the subsequent filter screen 7.

[0028] Furthermore, the arc plate 401 causes the roller 403 to move in contact with the filter screen 7, while the movable groove 305, in conjunction with the limiting rod 308, restricts the swing angle of the swing plate 309, causing the protrusions 404 on the roller 403 to vibrate and squeeze the surface of the filter screen 7, making the mesh of the filter screen 7 larger and promoting the falling off of impurities, thus ensuring the discharge effect of the filter screen 7. In this embodiment, the intercepting pipe can be applied to the sponge city design application in municipal engineering and landscape gardening, ensuring that sewage can be recycled and treated, and improving the utilization rate of water resources.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
