[0002] Pipeline desilting is to dredge the pipeline, clean the silt inside the pipeline, and keep it unobstructed for a long time to prevent urban waterlogging. Pipeline desilting has become an important task that cannot be ignored by the drainage department. If a large amount of debris and cement sand from infrastructure construction sites are discharged into the drainage pipeline, the pipeline will be blocked due to sedimentation and siltation. Failure to desilt and dredge the pipeline will cause sewage to overflow, pollute the environment, and cause trouble to people's lives.

[0003] However, the common dredging equipment in daily life is to remove the silt in the center of the pipe. The silt cleaning effect on the pipe wall is not good and residue is easily generated, resulting in poor overall dredging effect. Therefore, we have made improvements to this and proposed a dredging equipment for water supply and drainage projects. Summary of the invention

DETAILED DESCRIPTION

[0018] See also Figures 1 to 6The present invention provides a technical solution: a dredging equipment for water supply and drainage engineering, comprising a dredging shell 1, a connecting ring 2 is movably connected at the edge of one side of the dredging shell 1, a rotating shell 3 is fixedly connected to one side of the connecting ring 2, a scraper 4 is fixedly connected to one side of the rotating shell 3, a sludge transport bucket 5 is movably connected at the center of one side of the dredging shell 1, a cleaning device 6 is fixedly connected to the inner wall of the sludge transport bucket 5, the sludge transport bucket 5 is transmission-connected to the connecting ring 2 through a meshing device 7, and the meshing device 7 can cause the cleaning device 6 and the rotating shell 3 to rotate in the opposite direction to dredge.

[0019] A support frame 51 is fixedly connected inside the sludge transport bucket 5, a rotating rod 8 is fixedly connected at the center of the support frame 51, a drill bit 81 is fixedly connected to one end of the rotating rod 8, and a stirring device 82 is provided at the other end of the rotating rod 8; through the setting of the rotating rod 8, the stirring device 82 at the other end of the rotating rod 8 moves in the same direction as the sludge transport bucket 5 when the sludge transport bucket 5 rotates.

[0020] The cleaning device 6 includes a cleaning rod 61 fixedly connected to the inner wall of the sludge transport bucket 5 and a cleaning block 62 fixedly connected to the cleaning rod 61 , and the top of the cleaning block 62 is in contact with the inner wall of the scraper 4 .

[0021] There are two cleaning rods 61, and the cleaning blocks 62 on the two cleaning rods 61 are arranged in a staggered manner. By setting the staggered distribution of the cleaning blocks 62, when the two cleaning rods 61 are cleaning the sludge attached to the scraper 4, each area on the surface of the scraper 4 can be effectively cleaned, so that the scraper can better clean the inner wall of the pipe.

[0022] The meshing device 7 includes a first gear 71 meshed on the top of the sludge transport bucket 5 and a second gear 72 meshed on the inner side of the connecting ring 2. The first gear 71 and the second gear 72 mesh with each other. The first gear 71 is movably mounted on the side wall of the dredging shell 1 through a bearing. One side of the second gear 72 is transmission-connected to a motor 73, and the motor 73 is fixed to the side wall of the dredging shell 1.

[0023] A sludge storage tank 9 is provided at the bottom of the stirring device 82, and the sludge storage tank 9 is installed on the side wall of the dredging shell 1. A sludge discharge pipe 91 is provided on one side of the sludge storage tank 9. One end of the sludge discharge pipe 91 passes through the outside of the dredging shell 1 for connecting with an external silt extraction device. Because the length of the sludge discharge pipe 91 is not fixed, no matter how deep the dredging equipment enters the water supply and drainage pipe, the sludge discharge pipe 91 can discharge the sludge in the sludge storage tank 9 to the external silt extraction device.

[0024] The stirring device 82 includes a stirring rod 820 fixedly connected to one end of the rotating rod 8, and a crushing piece 821 is fixed on the surface of the stirring rod 820; through the setting of the crushing piece 821, the stirring device 82 can achieve a better stirring effect when stirring the sludge in the sludge storage tank 9, so that the sludge in the sludge storage tank 9 can be better discharged from the sludge discharge pipe 91.

[0025] The surface of the dredging shell 1 has an annular groove body 11, and a walking wheel group 12 is distributed in the annular groove body 11. Through the arrangement of the walking wheel group 12, when the dredging equipment enters the water supply and drainage pipeline for construction, the annular groove body contacts the inner wall area of ​​the water supply and drainage pipeline with a wider area, and the equipment can move forward more smoothly to perform dredging operations.

[0026] A first annular limiting protrusion 52 is formed on the outer side of the silt transport bucket 5, and an annular limiting groove 53 is formed on the dredging shell 1 at a position corresponding to the first annular limiting protrusion 52. The first annular limiting protrusion 52 and the annular limiting groove 53 can enable the silt transport bucket 5 and the dredging shell 1 to maintain relatively stable rotation.

[0027] A second annular limiting protrusion 31 is formed inwardly on the inner side of the rotating shell 3, and the second annular limiting protrusion 31 is close to the inner side of the sludge transport bucket 5; the second annular limiting protrusion 31 can make the rotating shell 3 rotate relatively stably along the wall of the water supply and drainage pipe, avoiding the influence of shaking on the effect of scraping sludge on the inner wall of the pipe.

[0028] Specifically, when the dredging equipment for water supply and drainage engineering is used: one end of the scraper 4 of the dredging equipment is placed at the opening of the water supply and drainage pipe that needs to be dredged, at this time, the outer side of the scraper 4 is in contact with the inner wall of the pipe, and the walking wheel group 12 is started to make the device move in the pipe to start dredging the pipe; Before desilting, the motor 73 is started to rotate the second gear 72, which drives the connecting ring 2 meshed on one side thereof to rotate, and the connecting ring 2 synchronously drives the rotating shell 31 and the scraper 4 thereon to rotate, thereby driving the scraper 4 to rotate and scrape the silt on the inner wall of the water supply and drainage pipe. The second gear 72 is meshed with the first gear 71 on one side, and the first gear 71 drives the silt transport bucket 5 meshed on one side thereof to rotate, so that the silt transport bucket 5 and the scraper 4 rotate in opposite directions. The rotation of the silt transport bucket 5 drives the cleaning plate 62 to rotate through the cleaning rod 61 therein, so that the cleaning plate 62 cleans the silt on the surface of the scraper 4; When the silt transport bucket 5 is rotating, the drill bit 81 removes the silt at the center of the pipeline, and the removed silt will fall into the sludge storage tank 9 through the silt transport bucket 5. When the removed silt falls into the sludge storage tank 9, the rotation of the rotating rod 8 drives the crushing piece 821 to rotate and stir, so that the removed silt is more fully decomposed. The silt after secondary decomposition is discharged to the outside of the pipe through the silt discharge pipe 91.

[0029] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
