Description

Technical Field

[0001] The utility model relates to the field of pipeline cleaning, in particular to an underwater pipeline inner wall cleaning device. Background Art

[0002] During the use of underwater pipelines, due to factors such as water scouring, corrosion and biological attachment, it is easy to form sediment rust and biological fouling on the inner wall of the pipeline. These foulings will not only reduce the water delivery efficiency of the pipeline, but may also cause safety problems such as pipeline rupture. At present, there are two types of existing cleaning equipment. One requires opening a hole in the pipeline and then cleaning the inside. This method can easily damage the structure of the pipeline itself and affect the subsequent use time of the pipeline. Another method uses a stick-like device that is inserted from one end of the pipeline and extended from the other end to clean the pipeline. This operation method requires longer tools for longer pipelines and is also very inconvenient to operate. Therefore, how to overcome the above-mentioned technical problems and defects has become a key issue that needs to be solved. Utility Model Content

[0027] See also Figure 1-Figure 4The underwater pipeline inner wall cleaning device of this embodiment can move on the inner wall of a longer pipeline with liquid to scrape off biological dirt and impurities attached to the inner wall of the pipeline. It can also wipe the inner wall of the pipeline after scraping off the dirt, so as to perform secondary cleaning on the inner wall of the pipeline. Moreover, it can collect the dirt that falls after scraping and wiping, so as to avoid the accumulation of dirt in the pipeline and blockage of the pipeline, thereby realizing the cleaning of the inner wall of the pipeline. In this embodiment, it mainly includes an operating frame 1 located on the upper side of the outer side of the pipeline and half wrapping the pipeline. The operating frame 1 is a C-shaped structure and its open end wraps the upper part of the pipeline. The bottom end of the operating frame 1 is fixedly provided with an electromagnet 6 in an arc structure. The electromagnet 6 is a mature prior art and will not be described in detail here. The bottom end of the operating frame 1 is fixedly provided with a handle 7, and the device is moved by the handle 7 for easy carrying. Anti-tilt rods 8 are fixedly provided at both ends of the operating frame 1, and rollers 9 that fit the curvature of the top of the pipeline are rotatably provided at the lower side of the end of each anti-tilt rod 8. Avoid tilting of the device when it moves on the pipeline, which will cause the suction of the electromagnet 6 to decrease and affect the cleaning effect. A control module is also provided. The electromagnet 6 is centrally controlled by the control module.

[0028] To enable the device to move on the pipeline. Figure 1-Figure 3 In this embodiment, a moving mechanism 2 for driving the operating frame 1 to move on the pipeline is fixedly provided on the operating frame 1 on both sides of the pipeline. The moving mechanism 2 includes a moving frame 21 fixedly provided on the end of the opening side of the operating frame 1, and the moving frame 21 is a C-shaped structure with its opening facing the pipeline. A crawler 22 that fits the side of the pipeline is rotatably provided in the middle of the moving frame 21, and a first motor 23 that drives the crawler 22 to work is fixedly provided on the moving frame 21. The first motor 23 is centrally controlled by a control module. The control module controls the first motor 23 to drive the crawler 22 to work, thereby moving the operating frame 1 on the pipeline through the moving frame 21, so as to facilitate the subsequent cleaning of the pipeline.

[0029] In order to clean the inner wall of the pipeline. Figure 2-Figure 4, a cleaning frame 3 is arranged inside the pipeline to move with the operating frame 1, and the cleaning frame 3 is made of magnetic materials such as iron and steel. The cleaning frame 3 is an arc-shaped structure designed to imitate the pipeline, and a plurality of balls 10 that can abut against the pipeline are arranged at the top of the cleaning frame 3. The balls 10 facilitate the movement of the cleaning frame 3 inside the pipeline to avoid being blocked by hard dirt inside the pipeline, which makes it impossible to move. A cleaning mechanism 4 that can rotate around the pipeline is arranged at the front of the cleaning frame 3. The cleaning mechanism 4 includes an inner gear ring 41 that is rotatably arranged at the bottom end of the cleaning frame 3, and the inner gear ring 41 is arranged coaxially with the cleaning frame 3. The inner gear ring 41 is made of a hard material such as a non-magnetic alloy. A second motor 42 is fixedly arranged at the rear side of the cleaning frame 3, and the second motor 42 is centrally controlled by a control module. The second motor 42 drives the inner gear ring 41 to rotate on the cleaning frame 3 through a gear 43 fixedly arranged at its output end. At least two cleaning brushes 44 are fixedly arranged horizontally at the front side of the inner gear ring 41. The second motor 42 is controlled by the control module to operate, so that the inner gear ring 41 rotates, and then the cleaning brush 44 rotates around the pipe to clean the inner wall of the pipe and remove most of the dirt from the inner wall of the pipe.

[0030] In order to collect the cleaned dirt. Figure 2-Figure 4 A collection unit 5 for collecting dirt is fixedly provided at the rear side of the cleaning rack 3. The collection unit 5 includes an annular sponge 51 fixedly provided at the rear side of the cleaning rack 3, and the outer ring of the annular sponge 51 fits with the inner wall of the pipe. The inner wall of the pipe is wiped by the annular sponge 51, so as to perform secondary cleaning on the inner wall of the pipe. A net bag 52 is fixedly provided at the rear side of the annular sponge 51, and a plurality of pull ropes 53 with knots are evenly distributed on the circumference of the annular sponge 51 outside the net bag 52. The dirt cleaned off the inner wall of the pipe is collected by the net bag 52 and the pull rope 53 to prevent the accumulation of dirt and blockage of the pipe.

[0031] The method of using the underwater pipeline inner wall cleaning device of the utility model is as follows: first, the pipeline is removed from the connection, and then the cleaning frame 3 is placed inside the pipeline and coaxial with the pipeline, and the ball 10 is fitted with the inner wall of the pipeline. After that, the operating frame 1 is placed on the outer wall of the pipeline above the cleaning frame 3 through the handle 7, and at this time, the two rollers 9 are fitted with the pipeline, the anti-tilt rod 8 makes the operating frame 1 in a vertical state, the electromagnet 6 is fitted with the pipeline, and the crawler 22 is fitted with the side of the pipeline. The electromagnet 6 is controlled to work by the control module, and at this time, the electromagnet 6 attracts the cleaning frame 3 to move upward, so that the ball 10 is fitted with the inner wall of the pipeline, and the cleaning brush 44 plays a certain guiding role. The first motor 23 and the second motor 42 are controlled to work by the control module, so that the crawler 22 rotates, thereby driving the operating frame 1 to move on the pipeline, and at this time, the roller 9 and the anti-tilt rod 8 make the operating frame 1 always vertical. The electromagnet 6 attracts the cleaning frame 3 to move with the operating frame 1 on the inner wall of the pipeline through the ball 10, so as to avoid the cleaning frame 3 being blocked by the hard dirt appearing inside the pipeline. At the same time, the second motor 42 drives the gear 43 to rotate, thereby driving the inner gear ring 41 to rotate on the cleaning frame 3, and the cleaning brush 44 scrapes and cleans the inner wall of the pipeline. During the movement of the cleaning frame 3, the pipeline after the dirt is scraped off is wiped by the annular sponge 51, and then the pipeline is cleaned again. The dirt dropped during the cleaning floats in the liquid in the pipeline. At this time, the dirt is collected by the net bag 52 and the pull rope 53 with a knot during the movement to avoid the situation that the dirt accumulates and blocks the pipeline. The cleaning frame 3 can be taken out when the belt device moves to the next pipeline connection.
