Description

Technical Field

[0001] This utility model relates to the field of pipe dredging technology, specifically a full-diameter hollow pull pipe dredging device. Background Technology

[0002] Domestic sewage is wastewater discharged from residents' daily lives, mainly originating from residential and public buildings, such as houses, government offices, schools, hospitals, shops, public places, and industrial enterprise toilets. To avoid environmental pollution and facilitate centralized treatment, existing technologies use sealed pipe networks for centralized collection and transportation.

[0003] However, the currently used fully sealed pipe network eliminates septic tanks and sedimentation manholes, so theoretically no sewage should accumulate inside the pipes. But as the usage time increases, scale will form on the inner wall of the pipe, and if it is not cleaned for a long time, the scale will become thicker and thicker, which will reduce the pipe diameter, affect the flow rate of sewage, and even cause pipe blockage. The existing technology uses a sewage truck to remove the settled sewage, which is effective, but cannot achieve the effect of thoroughly cleaning the inner wall of the pipe. In the end, it leads to high operating costs and low benefits. Therefore, in order to solve the above problems, this application will provide a full-diameter hollow pull-type pipe cleaner. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a full-diameter hollow pull-type pipe cleaner, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a full-diameter hollow pull-out pipe cleaner, including a cleaner body, a ring plate nested on the surface of the cleaner body, and a number of scrapers installed on the surface of the ring plate along its own circumference, and the sides of the scrapers can be bent and deformed to make way after being subjected to force.

[0006] Both ends of the main body of the drain cleaner are fitted with internal mounting frames, and an arc-shaped clearance groove is formed between the internal mounting frame and the inner wall of the main body of the drain cleaner. Both ends of the main body of the drain cleaner are provided with wire rope transition frames and wire rope coils. One end of the wire rope transition frame passes through the corresponding arc-shaped clearance groove and is locked around the internal mounting frame. One end of the wire rope coil is fixed to the surface of the other side of the wire rope transition frame.

[0007] The selected design features a 30-degree tapered structure at both ends of the main body of the drain cleaner, which facilitates its integration with the pipes to be cleaned. Furthermore, the main body of the drain cleaner is hollow, ensuring sufficient strength while optimizing its portability and creating favorable conditions for future portability.

[0008] Preferably, two ring plates are set, and several scrapers on the surface of the two ring plates are staggered and can fully cover the inner wall of the pipe to be cleaned. This ensures the cleaning effect while reducing the cleaning resistance pressure on the scrapers on each ring plate surface by cleaning in a zoned manner.

[0009] The selected scrapers are all tapered structures with a larger top and smaller bottom in an Ω shape, and both sides of the scrapers are provided with guide slopes. When the scrapers scrape the scale on the inner wall of the pipe to be cleaned in a straight motion, the guide slopes guide the scale that is cleaned out in strips downwards, so as to avoid the scale being constantly accumulated in the direction of the scraper's movement.

[0010] The selected scraper blades have an operating distance between the top surface of the scraper blades and the inner wall of the pipe to be cleaned between 0.01 and 0.25 mm to ensure the cleaning and unblocking effect, and the thickness of the thickest part of the scraper blades is less than 2 mm.

[0011] The selected scrapers are made of quenched spring steel plate material, which ensures that the scrapers have the structural strength for scraping while maintaining their own good elasticity. In addition, the edges and corners of the scrapers are set to rounded corners to avoid scratching the inner wall of the pipe to be cleaned during the reciprocating movement of the scrapers in the pipe, thus ensuring the reliability of the overall device operation.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The drain cleaner designed in this utility model can not only automatically remove scale from the inner wall of the pipe during use, but also reduce costs and improve efficiency, thereby ensuring that the fully sealed pipe network will not become clogged. It provides a good guarantee for the full-process sealed treatment of easily perishable organic pollutants and avoids the pollution of the atmosphere and water environment by the overflow of pollutants.

[0014] 2. The drain cleaner of this utility model has two ring plates and multiple scrapers on the surface of the two ring plates forming a double cleaning structure. When it moves into the pipe to be cleaned, the multiple scrapers on the surface of the two ring plates can fully cover the inner wall of the pipe to be cleaned in the cleaning space, and at the same time, the double scraping operation of moving back and forth can fully improve the cleaning effect of the inner wall of the pipe to be cleaned.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figure 1 , Figure 3-4 A hollow pull-out pipe cleaner with full diameter includes a cleaner body 1, a ring plate 2 nested on the surface of the cleaner body 1, and several scraper blades 3 installed on the surface of the ring plate 2 along its circumference, and the sides of the scraper blades 3 can be bent and deformed to make way when subjected to force.

[0025] Several scraper blades 3 are all in the form of an Ω-shaped conical structure with a larger top and a smaller bottom. Both sides of several scraper blades 3 are provided with guide slopes 7. The guide slopes 7 scrape the scale on the inner wall of the pipe to be cleaned while the corresponding scraper blade 3 is moving straight. The scale that is cleaned out in strips is guided downwards to avoid the scale being cleaned from accumulating in the direction of the scraper blade 3.

[0026] The working distance between the top surface of several scraper blades 3 and the inner wall of the pipe to be cleaned is between 0.01 and 0.25 mm to ensure the cleaning and unblocking effect, and the thickness of the thickest part of several scraper blades 3 is less than 2 mm.

[0027] Several scraper blades 3 are made of quenched spring steel plate material to ensure that the scraper blades 3 have the structural strength for scraping and maintain their own good elasticity. In addition, the edges and corners of several scraper blades 3 are set as rounded corners to avoid scratching the inner wall of the pipe to be cleaned during the reciprocating movement of the scraper blades 3 in the pipe to be cleaned, thus ensuring the reliability of the overall device operation.

[0028] Both ends of the main body 1 of the drain cleaner are fitted with an inner mounting frame 4, and an arc-shaped clearance groove is formed between the inner mounting frame 4 and the inner wall of the main body 1 of the drain cleaner. Both ends of the main body 1 of the drain cleaner are provided with a wire rope transition frame 5 and a wire rope coil 6. One end of the wire rope transition frame 5 passes through the corresponding arc-shaped clearance groove and is locked around the inner mounting frame 4. One end of the wire rope coil 6 is fixed to the surface of the other side of the wire rope transition frame 5.

[0029] In use, the existing upstream and downstream pipes that serve as reserved channels are dismantled to provide space for the installation of the main body 1 of the drain cleaner and to provide discharge space for the scale that has been cleaned. Then, one end of the steel wire rope reserved in the pipe to be cleaned is connected and fixed to the steel wire rope transition frame 5 on one side of the main body 1 of the drain cleaner. The steel wire rope transition frame 5 set on the other side of the main body 1 of the drain cleaner is fixed to one end of the steel wire rope coil 6 reserved in the upstream manhole. Then, the steel wire rope coil 6 reserved in the downstream manhole is connected to the existing electric winch for transmission, and the steel wire rope coil 6 reserved in the downstream manhole is connected away from the electric winch and to the other end of the steel wire rope reserved in the pipe to be cleaned.

[0030] After the above structures are assembled, start the electric winch. By winding up the steel wire, the main body 1 of the drain cleaner, the ring plate 2, and the multiple scraper blades 3 on the surface of the ring plate 2 can scrape away the scale on the inner wall of the pipe to be cleaned from upstream to downstream, thereby ensuring that the pipe is unobstructed.

[0031] The portion of the wire rope inside the wire rope coil 6, which was originally left in the upstream manhole, will be pulled into the cleaned pipe body and then used as a reserved wire rope for the pipeline. Similarly, the reserved wire rope for the pipeline will be fixed in the corresponding manholes at both ends through the small holes of the existing sealed manhole covers, in preparation for the next dredging.

[0032] Example 2

[0033] Please see Figure 1-6The main body 1 of the drain cleaner has a 30-degree tapered structure at both ends, which facilitates its assembly with the pipe to be cleaned. The main body 1 is hollow, which ensures that the main body 1 has sufficient strength while optimizing its portability. The number of ring plates 2 is two, and the scraper blades 3 on the surface of the two ring plates 2 are staggered and can fully cover the inner wall of the pipe to be cleaned. This ensures the cleaning effect while reducing the cleaning resistance pressure on the scraper blades 3 on the surface of each ring plate 2 by cleaning in sections.

[0034] In use, the two ring plates 2 and the multiple scrapers 3 on the surface of the two ring plates 2 form a double cleaning structure. During subsequent movement into the pipe to be cleaned, the multiple scrapers 3 on the surface of the two ring plates 2 can fully cover the inner wall of the pipe to be cleaned in the cleaning space, while the multiple scrapers 3 divide the inner wall of the pipe to be cleaned into multiple strip cleaning areas. With the double scraping effect of moving back and forth, the cleaning effect of the inner wall of the pipe to be cleaned is fully improved.
