Description

Technical Field

[0001] The present application relates to the technical field of water conservancy, and in particular to a device for cleaning the outer wall of a pipeline for water conservancy projects. Background Art

[0002] During the construction of water conservancy projects, a large number of water pipes will be used to transport water. After long-term use, a large amount of dust and garbage will remain on the surface of the water conservancy pipes. At this time, they need to be cleaned in time to prevent dust from corroding the surface of the water conservancy pipes.

[0003] Through searching, Chinese patent publication number CN 209140615 U discloses a rust removal device for the outer wall of a pipe used in a water conservancy project, comprising a support base, wherein the outer walls on both sides of the top of the support base are connected to a vertically arranged first support plate by bolts, and the top outer walls of the two first support plates are connected to the same horizontally arranged support top plate by bolts, the middle outer wall of one side of one of the first support plates is connected to a first hydraulic cylinder by a bearing, and the middle outer wall of one side of the other first support plate is connected to a rotating motor by bolts, and the outer walls of the adjacent sides of the output shaft of the first hydraulic cylinder and the rotating motor are both connected to a support column by bolts. The utility model proposes a rust removal device for the outer wall of a pipe used in a water conservancy project, which can collect and process rust residue generated during the rust removal process by providing a filter screen plate at the top of the third groove. The rust residue that falls into the third groove can be pulled out from one end of the support base, thereby preventing the rust residue from splashing and polluting the environment.

[0004] With respect to the above-mentioned related technologies, the inventors found the following defects: when removing rust from the surface of water conservancy pipelines, the pipelines are only fixed and then cleaned. However, during the cleaning process, the rust and impurities cleaned off the surface of the pipelines will remain on the surface and near the pipelines, which not only leads to incomplete cleaning, but also pollutes the environment of the pipeline cleaning work, requires manual secondary processing, and increases the labor intensity of workers.

A groove is provided at the bottom position of the support frame 3, and the width of the groove is greater than the diameter of the trachea 2. The support frame 3 is set in an "H" shape. The "H"-shaped support frame 3 avoids conflict with the outer side of the trachea 2, and the bottom of the support frame 3 is fixedly set in the middle of the outer side of the side clamping plate 1.

[0027] See also Figure 1 An air pump 5 is fixedly provided in the middle of the front of the support plate 7, and a connecting pipe 16 is provided in the middle of one side of the air pump 5. The end of the connecting pipe 16 away from the air pump 5 is connected to the main pipe 12. The connection between the main pipe 12 and the connecting pipe 16 is located in the middle. Both sides of the middle of the main pipe 12 are clamped with fixing buckles 22. One end of the fixing buckle 22 is fixedly provided on the top of the front of the I-frame 8, connecting the connecting pipe 16 with the middle of the main pipe 12. The air pump 5 transmits the high-pressure gas to both sides of the main pipe 12 through the connecting pipe 16.

[0028] See also Figure 1-2 Metal bellows 9 are provided at both ends of the main pipe 12. The end of the metal bellows 9 away from the main pipe 12 is connected to the air pipe 2. A nozzle 20 is fixedly provided on the side of the air pipe 2. The nozzle 20 passes through the middle of the side card plate 1 and is fixedly connected to the middle of the side card plate 1.

[0030] The implementation principle of the outer wall cleaning device for a water conservancy project in the embodiment of the present application is as follows: when in use, the side clamps 1 are placed on both sides of the pipeline, and the bottom of the pad 10 contacts the top of the pipeline. According to the diameter of the pipeline, the hydraulic column 4 is started to adjust the side clamps 1 to make an arc movement so that the bottom of the side clamps 1 contacts the outer wall of the pipeline, and the motor 21 is started to drive the first ratchet 17 to rotate. The first ratchet 17 drives the second ratchet 18 to rotate through the chain 15, so that the rotating wheel 13 inside the side clamp 1 rotates. The rotating wheel 13 grinds and cleans the outer wall of the pipeline through the grinding surface on the surface. The impurities and debris generated by the rotating wheel 13 during the rotation and cleaning process are started. The air pump 5 is generated. The gas inside the air pump 5 is ejected through the main pipe 12 and the air pipe 2 to blow away the generated debris and garbage, avoiding secondary cleaning of the pipeline, and metal bellows 9 are provided at both ends of the main pipe 12. When the side clamp 1 drives the air pipe 2 to make an arc movement, the metal bellows 9 can change in length to avoid damage to the air pipe 2 and the main pipe 12 during dragging.
