With the development of water conservancy and social productivity, it has continued to develop and become an important pillar of human civilization and economic development. The inner wall of the pipes used in water conservancy projects often adheres to some impurities and dirt, which will not only affect the circulation efficiency of the pipes over a long period of time, but also breed bacteria, so the pipes need to be cleaned regularly.

[0003] At present, the existing pipeline cleaning method mainly relies on workers to use cleaning tools to clean the pipeline, but this cleaning method is relatively labor-intensive and has relatively low efficiency; there are also simple mechanical equipment that enters the pipeline and uses a rotatable brush (generally a hard-bristle brush) to scrub the inner wall of the pipeline. Although the cleaning efficiency is improved, the cleaning effect is mixed. Since some dirt adhered to the inner wall of the pipeline is not easy to be scrubbed and cleaned, insufficient deep cleaning can easily lead to thicker dirt forming on the pipeline again within a period of time, which is not conducive to the cleaning, maintenance and long-term use of the pipeline; therefore, the technical personnel in this field provide a pipeline cleaning device for water conservancy projects to solve the problems raised in the above background technology.

[0023] Figure 1-Figure 4The utility model is a schematic diagram of the entire structure of a pipeline cleaning device for water conservancy projects. Figure 1-Figure 4 The present embodiment is a pipeline cleaning device for a water conservancy project, comprising a mobile trolley 10, the mobile trolley 10 moves and advances in the pipeline body H, the front end of the mobile trolley 10 is provided with a rotating drive assembly 20, the outer end of the rotating drive assembly 20 is provided with a coaxial mounting shaft 30, the outer end of the mounting shaft 30 is vertically fixed with a plurality of uniformly distributed first rotating rods 40 in a radial circle, the end of the first rotating rod 40 is provided with a positioning groove 40a, the inner side of the positioning groove 40a is rotatably provided with a rotating rod 40a and the outer end thereof extends to the outer side of the positioning groove 40a. The mounting plate 41 on the side, an elastic support member 42 is obliquely installed on one side of the positioning groove 40a and the other end abuts against one side of the upper part of the mounting plate 41, an arc scraper 43 is installed on the outer end of the mounting plate 41, and evenly distributed serrations 43a are provided on the edge of the arc scraper 43 that contacts the inner wall of the pipe body H; a plurality of second rotating rods 50 located behind the first rotating rod 40 are fixed to the radial circle of the outer wall of the mounting shaft 30, and a cleaning brush 51 in contact with the inner wall of the pipe body H is provided on the outer end of the second rotating rod 50.

[0024] The rotary drive assembly 20 includes a main shaft 21 rotatably mounted on the front end and inner side of the moving trolley 10 through a sleeve and a bearing, and a motor 22 arranged inside the moving trolley 10 and with the output end connected to the inner end of the main shaft 21. When in use, the entire device is pushed forward by the moving trolley 10, and of course it can also move backward. The motor 22 drives the main shaft 21 to rotate rapidly, and the main shaft 21 drives the installation shaft 30, the first rotating rod 40 and the second rotating rod 50 to rotate synchronously, and the inner wall of the pipeline is scraped and cleaned by the arc scraper 43 and the cleaning brush 51, saving time and effort.

[0025] Furthermore, the mobile cart 10 in this embodiment can be in a remote control form, a steering wheel driven form or a hand-pushed form, etc., and this embodiment does not limit this; in addition, the mobile cart 10 in this embodiment is matched with a pipe of corresponding model and size, so that the main shaft 21 can be coaxial with the pipe when driving, which is beneficial to the uniform cleaning of the brush.

Here, the PVC material used has excellent wear resistance and mechanical strength, and at the same time, with the arc structure, it will not damage the inner wall of the pipe when it is in friction contact with the pipe, and the dirt on the inner wall of the pipe also contains more water, which will not cause great wear to the scraper during scraping. At the same time, its elastic properties can form a good contact with the pipe, so that the scraping and cleaning effect is better; in addition, the scraper made of PVC material is very cheap, and the cleaning cost is relatively low.

[0028] The elastic support 42 is a coil spring; the positioning groove 40a also has a rotating shaft 44 that is rotatably connected to the root of the mounting plate 41; the arc scraper 43 and the mounting plate 41 are embedded in a structure and connected by bolts.

In specific use, when the mobile trolley 10 moves forward, the rotary drive assembly 20 drives the mounting shaft 30, the first rotating rod 40 and the second rotating rod 50 to rotate rapidly. At the same time, the radially rotating multiple arc scrapers 43 can form a close contact and automatic adjustment with the inner wall of the pipe under the support of the coil spring. At the same time, the arc scraper 43 can effectively destroy and scrape the dirt and impurities on the inner wall of the pipe with the cooperation of the sawtooth 43a, so that the bottom layer of dirt is effectively cleaned, and then the dirt is fully brushed for a second time by the cleaning brush 51, so that the inner wall of the pipe is effectively cleaned. It is simple and efficient, which is conducive to the later maintenance and long-term use of the pipeline.

[0029] In summary, in the present embodiment, a pipeline cleaning device for a water conservancy project is used. When the mobile trolley 10 moves forward, the rotating drive assembly 20 drives the mounting shaft 30, the first rotating rod 40 and the second rotating rod 50 to rotate rapidly. At the same time, the radially rotating multiple arc scrapers 43 can form a close contact and automatic adjustment with the inner wall of the pipeline under the support of the spiral spring. At the same time, the arc scraper 43 can effectively destroy and scrape away the dirt and impurities on the inner wall of the pipeline with the cooperation of the saw teeth 43a, so that the bottom layer of dirt is effectively cleaned, and then the dirt is fully brushed for a second time by the cleaning brush 51, so that the inner wall of the pipeline is effectively cleaned, which is simple and efficient.

[0030] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources.
