Description

Technical Field

[0001] This utility model belongs to the technical field of pipe cleaning devices, and relates to a retractable pipe cleaning device for building water supply and drainage. Background Technology

[0002] Building water supply and drainage pipelines are the piping systems inside buildings used for water supply and drainage. These systems are responsible for transporting domestic water, industrial water, fire-fighting water, sewage, etc., to ensure the normal operation of the city and the quality of life of residents.

[0003] Over time, the sludge and rust inside pipes solidify, causing the original pipe diameter to shrink. The sediment in the pipes produces hydrogen sulfide gas, which causes environmental pollution and can easily lead to combustion and explosion. Acids and alkalis in wastewater can easily corrode the pipe walls. Foreign objects in the pipes can cause blockages if they are not removed regularly.

[0004] Therefore, building water supply and drainage pipes need to be cleaned and maintained regularly to prevent blockages from affecting normal use.

[0005] Pipeline cleaning refers to cleaning pipelines to restore the original surface of the pipe material. After cleaning, a dense chemical passivation film is formed on the clean metal surface, which effectively prevents the re-generation of dirt and protects the equipment from corrosion or other chemical damage, thus ensuring equipment safety and extending its service life.

[0006] Cleaning building water supply and drainage pipes is an essential task. It can not only improve the efficiency of pipe transportation and reduce energy consumption, but also remove pipe dirt, eliminate secondary pollution, improve water quality, and protect people's physical and mental health.

[0007] However, existing pipes often use different sizes, and the cleaning parts of existing cleaning tools cannot be adapted to the pipe diameter. It is necessary to manually replace the cleaning parts with suitable ones according to the diameter of the municipal pipes, resulting in low cleaning efficiency.

[0008] For example, Chinese utility model patent CN220717081U, published on April 5, 2024, discloses a pipe cleaning device for building water supply and drainage, including a drive base, a cleaning base, and drive components. Multiple drive components are evenly and fixedly connected to the outer surface of the drive base. Each drive component includes a support rod, with a connecting seat fixedly connected to the end face of the support rod. A first motor is fixedly connected to the outer surface of the connecting seat, and the output end of the first motor slides through the connecting seat. A first rotating shaft is fixedly connected to the output end of the first motor, and a drive wheel is fixedly connected to the outer surface of the first rotating shaft. Although this pipe cleaning device can scrape off some dirt from the inner wall of the pipe and remove it from the pipe, it can only be used for cleaning pipes of the same fixed diameter. It is not convenient to use it for pipes of different diameters. Furthermore, the drive components have poor adhesion, causing the cleaning device to slip and become unable to move forward within the pipe. Utility Model Content

[0009] The purpose of this invention is to provide a retractable pipe cleaning device for building water supply and drainage, which solves the problem that existing pipe cleaning devices can only be used for cleaning pipes of the same fixed diameter, and have poor adhesion to the inner wall of the pipe, causing them to slip and be unable to move forward when moving inside the pipe.

[0010] The technical solution adopted by this utility model is a retractable pipe cleaning device for building water supply and drainage, comprising a drive assembly, a support assembly, and a water spray assembly fixedly connected in sequence. The drive assembly includes a bracket, a first motor installed inside the bracket, lifting columns installed around the bracket, a drive seat installed at the end of the lifting columns, a drive wheel and a second motor installed on the drive seat, and multiple silicone plates fixed around the sides of the drive wheel. The support assembly includes a support rod and a connecting block. One end of the support rod is fixedly connected to the bracket, and the other end is fixedly connected to the connecting block. A hollow rotating shaft is sleeved on the outside of the support rod, and a bearing is installed between the support rod and the hollow rotating shaft. The hollow rotating shaft is connected to the output shaft of the first motor through a coupling. Multiple silicone scrapers and multiple cleaning brushes are installed circumferentially on the outside of the hollow rotating shaft, and support wheels are installed around the connecting block.

[0011] The hollow rotating shaft has two rotating rings on its outer side. A silicone scraper is installed around the rotating ring near the first motor, and a cleaning brush is installed around the other rotating ring. Telescopic rods are installed between the silicone scraper, the cleaning brush and the corresponding rotating ring.

[0012] A second buffer plate is fixed between the silicone scraper, the cleaning brush and the corresponding telescopic rod. One end of the telescopic rod is fixed to the side of the rotating ring, and the other end is fixedly connected to the side of the second buffer plate.

[0013] The connecting block is fixed with lifting rods around its perimeter. The ends of the lifting rods are fixed with a first buffer plate and a support base, and the support wheels are mounted on the support base.

[0014] The telescopic rod consists of an outer tube, a piston, a tension spring, and an outer rod. One end of the outer tube is open, and the other end is fixed with a cover plate. The diameter of the open end is smaller than the inner diameter of the outer tube and the outer diameter of the piston. The tension spring and the piston are both installed inside the outer tube. The end of the piston away from the tension spring is fixedly connected to the outer rod, and the piston and the outer tube are slidably connected.

[0015] The structures of rising bollards, rising masts, and telescopic masts are the same.

[0016] The water spray assembly includes a water tank, with an inlet fixedly installed on the top of the water tank. One side of the water tank is fixedly connected to a connecting block, and an outlet is opened on the opposite side. A water pump, a rotating nozzle, and a spray nozzle are installed sequentially on the outlet.

[0017] A damping spring is installed between the lifting column and the drive seat.

[0018] Each drive unit is equipped with two drive wheels arranged side by side.

[0019] A power connection cable is provided between the bracket and the drive base. One end of the power connection cable is connected to the second motor, and the other end is used to connect to the power supply.

[0020] The beneficial effects of this utility model are as follows:

[0021] (1) The pipe cleaning device is composed of a drive component, a support component, a water spray component, a silicone scraper and a cleaning brush. The drive component drives the entire pipe cleaning device to move forward in the pipe. The water spray component sprays water to rinse the inner wall of the pipe. The cleaning brush scrubs the pipe after the water spray. Then the silicone scraper scrapes off the stains after scrubbing, thus completing the cleaning of the inner wall of the pipe. The cleaning effect is good and the device is highly practical.

[0022] (2) The drive assembly includes a bracket, a first motor is installed inside the bracket, lifting columns are installed around the bracket, a drive seat is installed at the end of the lifting columns, and a drive wheel and a second motor are installed on the drive seat. Multiple silicone plates are fixed around the side of the drive wheel. The silicone plates have a large friction force. When the cleaning device is placed into the pipe to be cleaned, the lifting column can make the cleaning device suitable for cleaning pipes with different inner diameters. The deformation of the silicone plates around the drive wheel fits against the inner wall of the pipe, thereby increasing the friction force of the drive wheel and achieving an anti-slip effect. This avoids the problem of the pipe cleaning device for building water supply and drainage sliding and being unable to move forward when moving inside the water supply and drainage pipe, thus improving the practicality of the pipe cleaning device for building water supply and drainage.

[0023] (3) Two rotating rings are fitted on the outside of the hollow rotating shaft. The silicone scraper is installed around the rotating ring near the first motor, and the cleaning brush is installed around the other rotating ring. A telescopic rod is installed between the silicone scraper, the cleaning brush and the opposite rotating ring. By extending and retracting the telescopic rod, the silicone scraper and the cleaning brush can be closely attached to the inner wall surface of the pipe to be cleaned, which improves the cleaning effect of the cleaning device on the inner wall of the pipe.

[0024] (4) A second buffer plate is fixed between the silicone scraper, the cleaning brush and the relative telescopic rod. One end of the telescopic rod is fixed on the side of the rotating ring, and the other end is fixedly connected to the side of the second buffer plate. The shrinkage of the second buffer plate can improve the adhesion between the silicone scraper, the cleaning brush and the inner wall of the pipe, thereby improving the cleaning effect of the pipe cleaning device used for building water supply and drainage. The operation of the hollow rotating shaft can drive the two rotating rings to rotate, thereby driving the cleaning brush to scrub the pipe after spraying water.

[0025] (5) A lifting rod is fixed around the connecting block. A first buffer plate and a support seat are fixed at the end of the lifting rod. The support wheel is installed on the support seat. By lifting the lifting rod, the support wheel around the block can be pushed to fit against the inner wall of the water supply and drainage pipe, thus achieving the effect of support and balance. The buffer of the first buffer plate can improve the fit between the support wheel and the inner wall of the pipe. This pushes the drive wheel to fit against the inside of the pipe for support, thereby improving the stability of the pipe cleaning device used for building water supply and drainage.

[0026] (6) The telescopic rod consists of an outer tube, a piston and a tension spring. The tension spring is located inside the outer tube. One end of the piston is located inside the outer tube and the other end is located outside the outer tube. The piston and the outer tube are slidably connected. The lifting column, lifting rod and telescopic rod have the same structure. Before the telescopic pipe cleaning device enters the pipe to be cleaned, the tension springs in the lifting column, lifting rod and telescopic rod are in a natural state. After the telescopic pipe cleaning device is pushed into the pipe to be cleaned, the tension springs in the lifting column, lifting rod and telescopic rod are in a compressed state. The reaction force of the tension spring pushes the drive wheel, support wheel, silicone scraper and cleaning brush to stick to the inner wall of the pipe to be cleaned, thereby cleaning the inner wall of the pipe and improving the stability of the pipe cleaning device used for building water supply and drainage.

[0027] (7) The water spray assembly includes a water tank, with an inlet fixedly installed on the top of the water tank. One side of the water tank is fixedly connected to the connecting block, and the opposite side has an outlet. A water pump, a rotating nozzle and a spray nozzle are installed on the outlet in sequence. Water can be added to the water tank through the inlet. The water pump draws water into the rotating nozzle, and the rotating nozzle sprays water out from the spray nozzle to achieve flushing of the inner wall of the pipe. Attached Figure Description

A telescopic rod 32 is installed between the silicone scraper 34, the cleaning brush 35 and the corresponding rotating ring 31. The distance between the silicone scraper, the cleaning brush and the axis of the hollow rotating shaft is adjusted by extending and retracting the telescopic rod. First, the inner wall of the pipe is scrubbed with the cleaning brush, and then the stains after scrubbing are scraped off with the silicone scraper. A cleaning brush is also fixed on one side of the silicone scraper 34. The simultaneous brushing and scraping improves the cleaning effect on the inner wall of the pipe.

Multiple silicone plates 15 are fixed around the sides of the drive wheel 14. The silicone plates have high friction. By deforming the silicone plates around the drive wheel to fit against the inner wall of the pipe, the friction of the drive wheel can be increased, which can play an anti-slip role and avoid the problem of the pipe cleaning device for building water supply and drainage sliding and being unable to move forward when moving inside the water supply and drainage pipe.

[0044] The support assembly 2 includes a support rod 25 and a connecting block 21.

The drive assembly 1 includes a bracket 17, inside which a first motor is installed. Lifting columns 11 are installed around the bracket 17, and a drive seat 13 is installed at the end of the lifting columns 11. A drive wheel 14 and a second motor 18 are installed on the drive seat 13 and are connected to each other. Multiple silicone plates 15 are fixed around the sides of the drive wheel 14.

[0058] The telescopic rod 32 consists of an outer tube 5, a piston 6, a tension spring 7, and an outer rod 8. One end of the outer tube 5 is open, and the other end is fixed with a cover plate. The diameter of the open end is smaller than the inner diameter of the outer tube and the outer diameter of the piston.

The lifting column 11, lifting rod 22, and telescopic rod 32 have the same structure. Before the telescopic pipe cleaning device enters the pipe to be cleaned, the tension springs in the lifting column, lifting rod, and telescopic rod are all in a natural state. After the telescopic pipe cleaning device is pushed into the pipe to be cleaned, the tension springs in the lifting column, lifting rod, and telescopic rod are all in a compressed state. The reaction force of the tension spring pushes the drive wheel, support wheel, silicone scraper, and cleaning brush to adhere tightly to the inner wall of the pipe to be cleaned, thereby cleaning the inner wall of the pipe and improving the stability of the pipe cleaning device used for building water supply and drainage.

[0059] See Figure 6 The water spray assembly 4 includes a water tank 45, with an inlet 41 fixedly installed on the top of the water tank 45.

Support wheels 24 are installed around the connecting block 21.

[0062] A damping spring 12 is installed between the lifting column 11 and the drive seat 13. Two drive wheels 14 are arranged in parallel on each drive seat 13. When the pipe cleaning device is placed into the pipe to be cleaned, the damping spring 12 is in a compressed state. Its rebound force increases the adhesion between the drive wheel and the inner wall of the pipe. At the same time, the deformation of the silicone plate around the drive wheel adheres to the inner wall of the pipe, thereby increasing the friction of the drive wheel and achieving an anti-slip effect.
