Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology, and specifically discloses a self-cleaning drainage pipe. Background Technology

[0002] Drainage pipes refer to a system consisting of pipes and ancillary facilities that collect and discharge sewage, wastewater, and rainwater. This includes main pipes, branch pipes, and pipes leading to treatment plants. Regardless of whether they are built on streets or elsewhere, any pipe that serves a drainage function can be called a drainage pipe. Drainage pipes typically have filter plates installed to filter large particles of impurities in the sewage. These filter plates are prone to clogging after a period of use and require cleaning. Furthermore, impurities easily adhere to the inner walls of the pipes, and prolonged neglect of cleaning can easily lead to blockages.

[0003] Currently, common drainage pipe cleaning technologies mainly employ mechanical scraping, high-pressure water flushing, or chemical cleaning. However, these methods often suffer from high energy consumption, complex structures, or high maintenance costs. For example, mechanical scraping devices require additional power, increasing system energy consumption; high-pressure water flushing relies on specialized equipment, making continuous cleaning difficult; and chemical cleaning may cause environmental pollution. Furthermore, existing technologies typically optimize only a single issue related to filter plates or the inner wall of pipes, lacking a holistic solution, resulting in limited cleaning effectiveness. Therefore, a self-cleaning drainage pipe solution is needed to address this problem. Utility Model Content

[0004] This invention proposes a self-cleaning drainage pipe that achieves automatic cleaning of the drainage pipe through a rotating brush and spiral scraper driven by water flow. At the same time, it adopts a detachable filter plate and a slag collection device to achieve the beneficial effects of zero energy consumption, anti-clogging, and convenient maintenance.

[0005] This utility model is implemented as follows: a self-cleaning drainage pipe includes a pipe body with an inlet and an outlet. The outer wall of the pipe body is provided with a shell, and a filter plate is detachably connected inside the shell. A cleaning mechanism is provided on the inner wall of the pipe body. The cleaning mechanism includes two collars, and a rotating shaft is rotatably connected inside the two collars. A brush plate that abuts against the filter plate is fixedly connected to one end of the rotating shaft near the filter plate. Multiple blades are fixedly connected to the outer wall of the rotating shaft near the inlet end. Multiple connecting rods are fixedly connected to the outer wall of the rotating shaft, and spiral scrapers are fixedly connected to the outer walls of the multiple connecting rods.

[0010] As a preferred embodiment of the self-cleaning drainage pipe of this utility model, multiple support rods are fixedly connected to the outer walls of both collars, and the other ends of the multiple support rods are fixedly connected to the inner wall of the pipe body.

[0011] As a preferred embodiment of the self-cleaning drainage pipe of this utility model, the spiral scraper is made of thermoplastic elastomer material.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model uses a water-driven paddle-driven rotating shaft to synchronously rotate the brush plate and spiral scraper, achieving automatic cleaning of the filter plate and continuous scraping of impurities from the inner wall of the pipe. It utilizes fluid kinetic energy to replace external electric or mechanical power, completing self-cleaning with zero additional energy consumption, and effectively preventing filter plate pore blockage and pipe wall deposit accumulation.

Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0022] Please see Figure 1-4 A self-cleaning drainage pipe includes a pipe body 1 with an inlet end 101 and an outlet end 102. The outer wall of the pipe body 1 is provided with a shell 2. A filter plate 3 is detachably connected inside the shell 2. A cleaning mechanism is provided on the inner wall of the pipe body 1. The cleaning mechanism includes two collars 4. A rotating shaft 6 is rotatably connected inside the two collars 4. A brush plate 7 that abuts against the filter plate 3 is fixedly connected to one end of the rotating shaft 6 near the filter plate 3. Multiple blades 8 are fixedly connected to the outer wall of the rotating shaft 6 near the inlet end 101. Multiple connecting rods 10 are fixedly connected to the outer wall of the rotating shaft 6. A spiral scraper 9 is fixedly connected to the outer wall of the multiple connecting rods 10.

[0023] In this embodiment: during drainage, the water flow washes the blade 8, which in turn drives the blade 8 to rotate. The blade 8 further drives the rotating shaft 6 to rotate, which in turn drives the brush plate 7 to rotate. The brush plate 7 cleans the filter plate 3 to prevent the filter plate 3 from clogging. When the rotating shaft 6 rotates, it further drives the connecting rod 10 to rotate, which in turn drives the spiral scraper 9 to rotate, scraping away impurities from the inner wall of the pipe body 1. The scraped-off impurities move to the right with the spiral scraper 9 and are discharged from the slag discharge port 11. This utility model uses the water flow to drive the brush plate 7 and the spiral scraper 9 to rotate and clean the filter plate 3 and the inner wall of the pipe, achieving zero-energy self-cleaning and good performance.

[0024] As a technical optimization of this utility model, the upper end face of the filter plate 3 is fixedly connected to the mounting plate 301, and the mounting plate 301 is detachably connected to the housing 2 by bolts and nuts.

[0025] In this embodiment, the filter plate 3 is installed inside the housing 2 by bolts and nuts, which facilitates the disassembly of the filter plate 3 for replacement or deep cleaning.

[0026] As a technical optimization of this utility model, a slag discharge port 11 is provided at the lower end of the pipe body 1 near the filter plate 3. A collection box 12 is threadedly connected to the outer wall of the slag discharge port 11, and a filter screen 14 is provided on the inner wall of the collection box 12.

[0027] In this embodiment: the cleaned-up impurities enter the collection box 12 from the slag discharge port 11, and the water in the impurities is filtered by the filter screen 14 inside the collection box 12. The collection box 12 is removed periodically to clean the impurities in a unified manner.

[0028] As a technical optimization of this utility model, a drain outlet 13 is provided at the lower end of the collection box 12.

[0029] In this embodiment, the water filtered from the collection box 12 can be discharged through the drain outlet 13.

[0030] As a technical optimization of this utility model, the collection box 12 is funnel-shaped.

[0031] In this embodiment, the collection box 12 is made into a funnel shape to facilitate the discharge of filtered water from the drain outlet 13.

[0032] As a technical optimization of this utility model, multiple support rods 5 are fixedly connected to the outer walls of the two collars 4, and the other ends of the multiple support rods 5 are fixedly connected to the inner wall of the pipe body 1.

[0033] In this embodiment, the support rod 5 facilitates the fixing of the collar 4, thus keeping the collar 4 stable.

[0034] As a technical optimization of this utility model, the spiral scraper 9 is made of thermoplastic elastomer TPE material.

[0035] In this embodiment: thermoplastic elastomer (TPE) is between rubber and plastic, with a wide hardness range (30-90 Shore A), adjustable to medium hardness, and has both elasticity and wear resistance.

[0036] The working principle and usage process of this utility model are as follows: During drainage, the water flow washes the blade 8, which in turn drives the blade 8 to rotate. The blade 8 further drives the rotating shaft 6 to rotate, which in turn drives the brush plate 7 to rotate. The brush plate 7 cleans the filter plate 3 to prevent the filter plate 3 from clogging. When the rotating shaft 6 rotates, it further drives the connecting rod 10 to rotate, which in turn drives the spiral scraper 9 to rotate, scraping off the impurities on the inner wall of the pipe body 1. The scraped impurities move to the right with the spiral scraper 9 and enter the collection box 12 from the slag discharge port 11. The water in the impurities is filtered by the filter screen 14 inside the collection box 12. The filtered water is discharged from the drain port 13. The collection box 12 is removed periodically to clean the impurities. This utility model uses the water flow to drive the brush plate 7 and the spiral scraper 9 to rotate and clean the filter plate 3 and the inner wall of the pipe, achieving zero-energy self-cleaning and good performance.
