Description

Technical Field

[0001] This utility model relates to the field of RTP pipeline cleaning technology, and more specifically to an RTP pipeline inner wall cleaning device. Background Technology

[0002] RTP pipe, short for reinforced thermoplastic pipe, is a new type of composite pipe. It uses thermoplastic plastics (such as polyethylene PE, polypropylene PP, etc.) as the inner and outer layers, with a fiber reinforcement layer (such as glass fiber, aramid fiber, etc.) in between to provide structural strength. Therefore, it combines the corrosion resistance and flexibility of plastics with the high strength of composite materials. However, during long-term use, impurities (such as mud, rust, microbial metabolites), scale (such as calcium and magnesium ion precipitation, chemical media residues), or media residues (such as wax in crude oil, viscous substances from chemical raw materials) can easily accumulate on the inner wall of the pipe. These substances can reduce the inner diameter of the pipe, increase fluid resistance, lead to increased transport pressure, decreased flow rate, and even blockage, affecting the continuity of production. Existing technologies for cleaning the inner walls of RTP pipelines mostly employ high-pressure water jet cleaning. This method not only consumes a large amount of water resources, but also fails to thoroughly clean the dirt deep inside the pipeline. Another method involves using mechanical scraping tools inside the pipeline, such as rotary scrapers, which move inside the pipeline with the help of fluid propulsion or mechanical traction to scrape off the hard scale and sticky substances attached to the inner wall. However, this scraping process can easily damage the inner wall of the pipeline, making it impractical. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides an inner wall cleaning device for RTP pipelines to solve the problems existing in the background art.

[0004] The utility model provides the following technical solution: an inner wall cleaning device for RTP pipelines, including a base, a support plate fixedly connected to the top of the base, a reel one and a reel two rotatably connected to the surface of the support plate via bearings, two guide frames fixedly connected to the surface of the support plate, a traction rope wound on the surface of the reel one, and an air guide tube wound on the surface of the reel two, with a sealing assembly installed at the end of the traction rope and the air guide tube away from the support plate, a crank handle fixedly connected to the center of the surface of the reel one rotatably connected to the surface of the support plate, and toothed rings fixedly connected to the center of the surfaces of both the reel two and the reel one, with toothed belts meshing on the outer surfaces of the two toothed rings.

[0005] Furthermore, the end of the air guide pipe away from the sealing assembly passes through the inner center of the second reel and extends to the outside of the support plate, where a right-angle elbow is installed. The end of the right-angle elbow away from the air guide pipe is fixedly connected to a valve core valve. That is, when the second reel rotates, it drives the right-angle elbow and the valve core valve to rotate synchronously.

[0006] Furthermore, the sealing assembly includes a spherical airbag fixedly connected to the outer surface of the traction rope and the air guide tube. A spherical protective sleeve is fixedly connected to the outer surface of the spherical airbag. A wear-resistant sleeve is movably sleeved at the center of the surface of the spherical protective sleeve. The outer diameter of the wear-resistant sleeve is larger than the inner diameter of the pipe. A reinforcing plate is fixedly connected to the inner wall of the spherical airbag. The outer surface end faces of the traction rope and the air guide tube are both fixedly connected to the inside of the reinforcing plate.

[0007] Furthermore, the surface of the guide frame is provided with through holes, the traction rope is a soft steel wire, and the length of the traction rope reserved on the outside is less than that of the air guide tube, that is, when the traction rope is tightened, the air guide tube is in a non-tightened state.

[0008] Furthermore, anti-slip strips are fixedly bonded at equal intervals to the outer surface of the spherical protective sleeve, and the material of the spherical protective sleeve is silicone.

[0009] Furthermore, the wear-resistant sleeve is ring-shaped, and the wear-resistant sleeve is formed by wrapping and bonding hemp rope in a ring with adhesive.

[0010] The technical effects and advantages of this utility model are as follows: 1. Compared to traditional high-pressure water jet cleaning methods, this device does not consume a large amount of water. Cleaning is achieved through the friction between the wear-resistant sleeve in the sealing component and the inner wall of the pipe, making it more energy-efficient and environmentally friendly. Furthermore, the sealing component can penetrate deep into the pipe, solving the problem of incomplete cleaning of deep-seated dirt using traditional methods. Compared to mechanical scraping tools, this device uses a spherical airbag that expands to drive the wear-resistant sleeve to rub against the inner wall, avoiding damage to the pipe's inner wall caused by rigid scraping. It is particularly suitable for RTP pipes, which combine plastic properties with composite material structures, better protecting the pipe body and extending its service life. Simultaneously, the crank handle drives reels one and two to reel synchronously, stably controlling the movement speed and force of the sealing component within the pipe, ensuring uniform cleaning and avoiding inadequate cleaning or excessive friction in certain areas.

[0011] 2. In this utility model, the spherical protective sleeve in the sealing assembly is made of silicone and equipped with anti-slip strips, which can enhance the stability of the fit with the inner wall of the pipe and reduce wear on the pipe. The wear-resistant sleeve made of hemp rope is not only low in cost, but also has good wear resistance after being rolled into a ring with adhesive. It can be replaced separately after wear, reducing maintenance costs. Reel 1 and Reel 2 achieve synchronous rotation through toothed rings and toothed belts, ensuring the coordination of the winding and unwinding of the traction rope and the air guide tube. The design of the traction rope having a reserved length smaller than the air guide tube avoids the air guide tube being over-tightened and damaged during winding, thus extending the service life of the air guide tube. The setting of the valve core valve and the right angle elbow facilitates the connection to the booster equipment. When Reel 2 rotates, both rotate synchronously, ensuring stable gas delivery and preventing the gas supply from being affected by the rotation of the reels, thereby improving the reliability of the device operation.

Detailed Implementation

[0014] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0015] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0016] An internal wall cleaning device for RTP pipelines includes a base 1, a support plate 2 fixedly connected to the top of the base 1, a reel 3 and a reel 4 rotatably connected to the surface of the support plate 2 via bearings, two guide frames 5 fixedly connected to the surface of the support plate 2, a traction rope 31 wound on the surface of the reel 3, an air guide tube 41 wound on the surface of the reel 4, a sealing assembly 10 installed at the end of the traction rope 31 and the air guide tube 41 away from the support plate 2, a crank 6 rotatably connected to the surface of the support plate 2 and fixedly connected to the center of the surface of the reel 3, toothed rings 8 fixedly connected to the center of the surfaces of the reel 4 and the reel 3, and toothed belts 9 meshing on the outer surfaces of the two toothed rings 8.

[0017] In this embodiment, reel 1 3 and reel 2 4 rotate synchronously through toothed ring 8 and toothed belt 9. With the operation of crank 6, the traction rope 31 and air duct 41 can be wound up and down at the same time, ensuring the stability of the sealing component 10 in the pipeline and avoiding tilting or jamming of the sealing component 10 due to inconsistent winding and unwinding speeds, thus improving the smoothness of the cleaning process.

[0018] The through holes on the surface of the guide frame 5 guide the traction rope 31 and the air duct 41, preventing them from getting tangled or deviating from the track during the winding and unwinding process, ensuring that the sealing assembly 10 moves along the pipeline axis and ensuring uniform cleaning.

[0019] Specifically, the end of the air guide pipe 41 away from the sealing assembly 10 passes through the center of the inside of the reel 2 4 and extends to the outside of the support plate 2, where a right-angle elbow 7 is installed. The end of the right-angle elbow 7 away from the air guide pipe 41 is fixedly connected to the valve core valve 71. That is, when the reel 2 4 rotates, it drives the right-angle elbow 7 and the valve core valve 71 to rotate synchronously.

[0020] In this embodiment, the end of the air guide tube 41 away from the sealing assembly 10 is connected to the right-angle elbow 7 and the valve core valve 71. The valve core valve 71 facilitates quick connection to external pressurization equipment (such as an air pump) to realize the inflation and deflation control of the spherical airbag 101.

[0021] When the reel 2 4 rotates, it drives the right-angle elbow 7 and the valve core valve 71 to rotate synchronously, preventing the air guide tube 41 from twisting or breaking due to the rotation of the reel 2 4, ensuring the continuity and stability of gas delivery, and ensuring that the spherical airbag 101 can continue to maintain an inflated state.

[0022] Specifically, the sealing assembly 10 includes a spherical airbag 101 fixedly connected to the outer surface of the traction rope 31 and the air duct 41. A spherical protective sleeve 102 is fixedly connected to the outer surface of the spherical airbag 101. A wear-resistant sleeve 103 is movably sleeved at the center of the surface of the spherical protective sleeve 102. The outer diameter of the wear-resistant sleeve 103 is larger than the inner diameter of the pipe. A reinforcing plate 104 is fixedly connected to the inner wall of the spherical airbag 101. The outer end faces of the traction rope 31 and the air duct 41 are both fixedly connected to the inside of the reinforcing plate 104.

[0023] In this embodiment, after the spherical airbag 101 is inflated, it can drive the spherical protective sleeve 102 and the wear-resistant sleeve 103 to fit tightly against the inner wall of the pipe. The dirt is cleaned by friction. Its spherical structure can adapt to the curvature of the inner wall of the pipe, ensuring uniform contact with the inner wall and cleaning without dead corners.

[0024] The reinforcing plate 104 fixes the traction rope 31 and the air duct 41 inside the spherical airbag 101, enhancing the connection strength between the two and the sealing assembly 10, preventing them from falling off due to excessive force during traction, and improving the safety of the device.

[0025] The outer diameter of the wear-resistant sleeve 103 is larger than the inner diameter of the pipe. After the spherical airbag 101 expands, it can tightly squeeze the inner wall of the pipe and effectively remove impurities and scale attached to the inner wall through friction, ensuring the cleaning effect.

[0026] Specifically, the guide frame 5 has through holes on its surface, the traction rope 31 is a soft steel wire, and the length of the traction rope 31 reserved on the outside is less than that of the air guide tube 41. That is, when the traction rope 31 is tightened, the air guide tube 41 is in a non-tightened state.

[0027] In this embodiment, the traction rope 31 is made of soft steel wire, which has both flexibility and high strength. It can go deep into the pipe with the sealing component 10 and provide sufficient traction force to pull the sealing component 10 to move, and it is not easy to break.

[0028] The length of the traction rope 31 reserved on the outside is less than that of the air tube 41. When the traction rope 31 is tightened, the air tube 41 is in a non-tightened state, which avoids damage to the air tube 41 due to excessive force and extends the service life of the air tube 41.

[0029] Specifically, anti-slip strips are fixedly bonded at equal intervals on the outer surface of the spherical protective cover 102, and the material of the spherical protective cover 102 is silicone.

[0030] In this embodiment, the spherical protective sleeve 102 is made of silicone, which is soft and elastic. It can buffer the frictional impact between the wear-resistant sleeve 103 and the inner wall of the pipe, avoid scratching the inner wall of the pipe, and protect the composite structure of the RTP pipe.

[0031] The anti-slip strips on the outer surface of the spherical protective sleeve 102 increase the friction with the wear-resistant sleeve 103, preventing the wear-resistant sleeve 103 from sliding or shifting during friction, ensuring stable contact between the wear-resistant sleeve 103 and the inner wall of the pipe, and improving the cleaning effect.

[0032] Specifically, the wear-resistant sleeve 103 is a ring shape, which is made of hemp rope and is fixed by wrapping and bonding it in a ring shape with adhesive.

[0033] In this embodiment, the wear-resistant sleeve 103 is formed by bonding hemp rope in a ring with adhesive. Hemp rope is a low-cost material with good wear resistance, which can effectively cope with the friction of the inner wall of the pipe and is not easily damaged after long-term use.

[0034] The wear-resistant sleeve 103 is annular and movably fitted onto the surface of the spherical protective sleeve 102. When the wear is severe, it can be disassembled and replaced separately without replacing the entire sealing assembly 10, which greatly reduces maintenance costs and replacement difficulty.

[0035] The working principle and usage process of this utility model are as follows: During use, the traction rope 31 and the air guide pipe 41 are simultaneously unwound, and the sealing assembly 10 is inserted deep into the pipe. Then, the pressure booster is connected to the valve core valve 71, and high-pressure gas enters the spherical airbag 101 through the valve core valve 71, the right-angle elbow 7, and the air guide pipe 41. After the spherical airbag 101 inflates, the surface of the wear-resistant sleeve 103 presses against the inner wall of the pipe. Then, the crank handle 6 drives the reel 3 to rotate clockwise. The reel 3, through the toothed ring 8 and the toothed belt 9, drives the reel 4 to rotate clockwise synchronously, and simultaneously... The traction rope 31 and the air guide tube 41 are wound up. The traction rope 31 pulls on the sealing component 10, causing the sealing component 10 to slide inside the pipe. The friction between the wear-resistant sleeve 103 and the inner wall of the pipe is used to clean the inner wall of the pipe. When the sealing component 10 is completely pulled out of the pipe, the pipe cleaning is completed. After water is turned on, the water flow will directly flush away the cleaned impurities and discharge them through the outlet of the pipe. When the wear-resistant sleeve 103 wears out, the pressure of the spherical airbag 101 is directly released. After the spherical airbag 101 is deflated to a certain extent, the wear-resistant sleeve 103 can be removed and replaced.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
