Description

Technical Field

[0001] The present invention relates to the technical field of pipeline cleaning, and specifically to an automated device for cleaning dirt from the inner wall of a water pipe. The device is suitable for cleaning the interior of household tap water pipes, municipal tap water pipes, industrial pipes, etc., and aims to improve the quality of drinking water, reduce secondary pollution, and extend the service life of filtering equipment. Background Art

[0002] Existing problems:

[0003] After long-term use, household water pipes are prone to accumulating contaminants such as scale, rust, bacteria, and biofilm. This contaminant not only breeds pathogenic microorganisms like E. coli and Legionella, leading to excessive bacterial counts in drinking water, but also releases heavy metal ions like lead and cadmium, directly threatening the health of the human digestive, immune, and nervous systems. According to statistics, approximately 80% of global diseases are related to contaminated drinking water, with secondary contamination of pipe networks being a major contributing factor. Traditional cleaning methods have significant limitations: chemical cleaning requires strong acid or alkaline solutions, which can corrode pipe materials and leave toxic residues. Furthermore, the water supply must be shut down during the process, disrupting residents' daily lives. High-pressure water jet cleaning, while capable of removing some dirt, carries the risk of rupture in older pipes and requires specialized equipment and training. The cost of a single service can reach 500-2000 yuan, making it difficult for ordinary households to adopt. In addition, most commercially available pipe cleaning tools are simple brush heads or magnetic cleaners with single functions and cannot adapt to different pipe diameters or complex pipe structures (such as 90° elbows and tee interfaces). They also lack real-time monitoring methods such as endoscopes, resulting in the cleaning effect relying on manual experience, and the blind spot rate exceeds 40%.

[0004] Social needs:

[0005] With the strict implementation of the "Sanitary Standard for Drinking Water" (GB 5749-2022), public awareness of drinking water quality has increased significantly. Surveys show that the average annual growth rate of household demand for pipe cleaning services in my country's first-tier cities has reached 25%. However, the existing market supply faces two major gaps: a lack of standardized, low-cost household solutions, and a lack of a large-scale, professional cleaning service industry chain. Therefore, developing an integrated, intelligent, and universally accessible pipe wall descaling device is both an urgent need to ensure residents' drinking water safety and an important path to promoting industrial upgrading. Summary of the Invention

[0006] The purpose of the present invention is to provide an integrated, adjustable, and easy-to-operate pipe inner wall descaling device to achieve the following goals:

[0007] Thoroughly remove dirt from the inner wall of the pipe to ensure the safety of drinking water;

[0008] Reduce dirt accumulation on the filter surface and extend its service life;

[0009] Adapt to different pipe diameters through modular design, lowering the threshold for use;

[0010] Promote the development of the pipe cleaning service industry and create employment opportunities.

[0011] To achieve the above objectives, the present invention provides the following technical solutions:

[0012] A pipe inner wall descaling device comprises an inflatable elastic protective body with an inflation port at the bottom thereof, which can be expanded by inflation to adapt to pipes of different diameters;

[0013] A power propeller is installed at the bottom end of the elastic guard, and a waterproof outer rotor brushless motor is installed inside the elastic guard. The bearing of the outer rotor brushless motor is a hollow bearing. The stator and bearing of the outer rotor brushless motor are fixed. The outer rotor rotates and drives the elastic guard and the power propeller to rotate. The power propeller is connected to the outer rotor, and the rotation of the outer rotor drives the power propeller to rotate, thereby providing forward or backward thrust and driving the device to move in the pipeline.

[0014] A detachable cleaning brush is attached around the power propeller to scrape dirt off the inner wall of the pipe;

[0015] A waterproof curved endoscope is provided at the hollow bearing port of the motor at the top of the elastic protective body, which is used to transmit the internal image of the pipeline in real time and assist in adjusting the forward direction of the device;

[0016] It also includes a control module, which includes a power supply line and a signal line passing through the hollow bearing, and an external controller for controlling the motor speed, the start and stop of the power propeller, and the endoscope monitoring function.

[0017] Furthermore, the elastic guard is made of elastic soft material, which can adapt to pipes of different diameters after inflation. The surface of the elastic guard is provided with spiral patterns. The device can be moved in the pipe by rotating the elastic guard, while enhancing the friction with the inner wall of the pipe to ensure the cleaning effect.

[0018] Furthermore, the elastic protective body is designed to be replaceable and can be replaced according to the internal pressure after inflation required for different tube diameters.

[0019] Furthermore, the hollow bearing is used to install a waterproof curved endoscope and to pass power lines and signal lines.

[0020] Furthermore, the cleaning brush is of replaceable design, including hard bristles, soft bristles or a combination thereof to adapt to different types of dirt.

[0021] Furthermore, the pipe inner wall descaling device is suitable for cleaning the inner walls of metal pipes, plastic pipes or composite material pipes, and is particularly suitable for household tap water pipes and municipal tap water pipes.

[0022] The present invention has the following beneficial effects:

[0023] Technical effect:

[0024] Cleaning efficiency is increased by more than 80%, and more than 99% of pipe wall attachments can be removed;

[0025] Wide adaptability, a single device can cover pipes of various types and diameters;

[0026] Extend the filter life by 3-5 years and reduce the user's replacement cost.

[0027] Social impact:

[0028] Promoting the industrialization of pipeline cleaning services is expected to create 50,000 to 100,000 jobs nationwide (including equipment production, installation, maintenance, etc.);

[0029] Reduce the use of chemical cleaners, reduce environmental pollution, and help achieve the "dual carbon" goals. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The device comprises an inflatable elastic body 1 made of a flexible, soft material (such as rubber, silicone, or other elastic composite materials). A gas inlet 2 is provided at the bottom of the body. The body adapts to pipes of different diameters by inflation. The surface of the body is provided with spiral patterns to enhance friction with the inner wall of the pipe, and the body can be rotated to move forward or backward within the pipe. The body is replaceable and can be changed according to the internal pressure required for inflation of different pipe diameters.

[0041] A power propeller 3 is mounted at the bottom end of the elastic guard 1, inside which is mounted a waterproof outer rotor brushless motor 5. The outer rotor brushless motor 5 has a hollow bearing 4 as its bearing. The power propeller 3 is connected to the outer rotor, and the rotation of the outer rotor drives the propeller to rotate, providing forward or backward thrust. The outer rotor of the outer rotor brushless motor 5 rotates, thereby driving the elastic guard 1 to rotate, realizing the movement function of the device. The hollow bearing 4 is used to mount a waterproof curved endoscope 6 and to pass through power supply and signal lines 7.

[0042] A detachable cleaning brush 9 is attached around the power propeller 3 to scrape dirt off the inner wall of the pipe. The cleaning brush is replaceable and includes hard bristles, soft bristles or a combination thereof to adapt to different types of dirt.

[0043] A waterproof curved endoscope 6 is provided at the top end of the elastic protective body 1 at the position of the hollow bearing port of the motor, which is used to transmit the internal image of the pipeline in real time and assist in adjusting the forward direction of the device, and has waterproof and anti-fog functions;

[0044] It also includes a control module, which includes a power supply line and a signal line 7 passing through the hollow bearing 4, and an external controller 8 for controlling the motor speed, the start and stop of the power propeller, and the endoscope monitoring function.

[0045] The pipe inner wall descaling device is suitable for cleaning the inner walls of metal pipes, plastic pipes or composite material pipes, and is particularly suitable for household tap water pipes and municipal tap water pipes.

[0046] How it works

[0047] Startup phase: Place the device into the pipe inlet, inflate to the appropriate pipe diameter, connect the power supply and start the motor;

[0048] Cleaning stage: The outer rotor brushless motor drives the elastic guard to rotate, while the power propeller provides auxiliary thrust to push the device forward or backward in the pipe; the cleaning brush scrapes the dirt on the inner wall; the curved endoscope monitors the cleaning effect in real time;

[0049] Recovery stage: After cleaning, the protective body is pulled out of the pipeline and deflated and contracted.

[0050] Example: Household water pipe cleaning

[0051] Select a PVC pipe with a suitable diameter and inflate the device until it fits the pipe wall;

[0052] Attach a cleaning brush around the propeller, start the motor, and spin it forward at 50 rpm;

[0053] Observe the dirt shedding through the bent endoscope and adjust the forward speed;

[0054] After cleaning is complete, deflate the air and flush the pipes with water to remove any residue.

[0055] The elastic guard of the device is a replaceable accessory, that is, it can be replaced when worn out, just like a cleaning brush.

[0056] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above and, without departing from the purpose of the present invention, designs structures and embodiments similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
