Abstract

The present invention relates to a water pipe cleaning device, comprising: a main body (10) formed with a cross-sectional shape smaller than the cross-sectional shape of the water pipe so as to be movable inside the water pipe; a driving unit (20) that drives the main body (10) using a plurality of driving wheels (201) installed on the lower side of the main body (10); a fixing unit (30) that fixes the main body (10) inside the water pipe using a plurality of guide lock members (301) installed on both sides of the main body (10); a shooting unit (40) installed on the front of the main body (10) to photograph the inside of the water pipe; and a control unit (50) that controls the operation of the driving unit (20) and the fixing unit (30) by remote control via a mobile device and transmits image information captured by the shooting unit (40) to the mobile device. According to the present invention, when moving inside a water pipe by remote control and reaching a part requiring internal cleaning, the device is fixed at that point and reduces the cross-sectional area inside the water pipe where scale has formed. This causes the scale to be cleaned by the increased pressure of the fluid passing through that point, thereby providing the effect of quickly and easily cleaning the inside of the water pipe.

Description

Water pipe cleaning device The present invention relates to a water pipe cleaning device, and more specifically, to a water pipe cleaning device that moves inside a water pipe by remote control and, upon reaching a part requiring internal cleaning, is fixed at that point to reduce the cross-sectional area inside the water pipe where scale has formed, thereby cleaning the scale by the increased pressure of the fluid passing through that point. Generally, when various fluid transport pipelines, such as large-diameter water pipes for supplying tap water, sewer pipes for transporting sewage, or pipelines for transporting various fluids such as oil or gas, are used for a long time after installation, they deteriorate. As a result, various foreign substances contained in fluids such as tap water, oil, and gas accumulate as sludge on the inner wall surface of the pipeline, or rust is generated as the inner surface of the pipeline oxidizes and hardens to form a scale layer. As described above, scale formed by the deposition of foreign substances on the inner surface of various fluid transport pipelines gradually thickens and hardens over time, which obstructs the smooth flow of fluid and causes a drop in fluid pressure. Additionally, the scale attached to the fluid transport pipeline dissolves into the fluid, causing contamination of the fluid, so the fluid transport pipeline must be cleaned periodically. Among the cleaning methods for fluid transport pipelines, there are various methods for removing scale deposited on the inner surface of the pipeline. Representative examples include a method combining the scraper method, which dredges sediment by towing equipment, and the water jet method using high-pressure water, as well as the polypig method, which removes scale from the inner surface of the pipe by propelling a polypig under high pressure. In other words, the method using a scraper and water jet involves first connecting a steel wire to a scraper larger than the diameter of the pipeline to be rehabilitated and pulling it out to the rear of the pipeline. Then, the steel wire is pulled at a constant speed to scrape off rust and scale attached to the inner wall of the pipeline. Afterward, high-pressure water supplied by a high-pressure pump is sprayed onto the inner wall of the pipeline through a high-pressure water spray nozzle attached to the tip of a high-pressure hose, thereby pushing the remaining residue, such as rust or scale removed by the scraper, out of the pipeline, and cleanly removing rust and scale from the inner surface of the pipeline. The above method, when removing rust and scale using a scraper, generally follows the principle of using a scraper with a diameter larger than that of the rehabilitated pipeline. However, when there is a large amount of rust and scale, not only does the pressure required to pull the scraper increase significantly, but the removed rust and scale also accumulate at the rear of the scraper, making it difficult for the scraper itself to move. Therefore, depending on the condition of the rust and scale, a small-sized scraper is inserted into the pipeline, followed by a series of steps in which scrapers of progressively larger sizes are inserted into the pipeline to remove the scale. Therefore, since cleaning requires repeatedly replacing scrapers of different sizes, there is a disadvantage in that the work is very cumbersome and takes a long time. In addition, the water jet, which is performed after removing rust and scale from the pipe by a scraper, is advanced by the nozzle through jet propulsion. Since the nozzle advances while pushing out various foreign substances and scale present in the pipe and removing scale attached to the inner surface of the pipe, the water jet process is not a function to remove scale from the inner surface of the pipe but rather to discharge foreign substances that have fallen into the pipe after scraping to the outside, and this also involves the inconvenience of having to go through repetitive work. Meanwhile, the polypig method, which is widely used as a mechanism to remove scale by transporting it using the fluid pressure of the pipeline, is effective for removing scale inside the pipeline because the polypig moves forward while rotating in a spiral direction due to the driving force of the fluid pressure. However, since the cleaning device inside the fluid transport pipeline is towed and cleaned using a wire from the ground, there are many cases where it is difficult to transport the cleaning device using only the towing force through the wire when passing through bent or curved parts of the fluid transport pipeline or when severe friction occurs between the pipeline and the cleaning device. As a result, not only is there a problem of significantly reduced quality and workability regarding the cleaning of the fluid transport pipeline, but there is also a problem in that there is no means to accurately determine the condition inside th
