Description

Technical Field

[0001] The utility model relates to an underground pipeline dredging and maintenance device, belonging to the technical field of pipeline construction. Background Art

[0002] Most underground drainage pipes are buried in shallow underground layers, and the diameter of the pipes is not large. Due to long-term use, the pipes will produce sedimentation and siltation of dirt, which leads to a further reduction in the flow of the pipes. For small-diameter pipes, if the siltation is serious, it will cause blockage. When the sediment accumulates too much or the pipe lining falls off and blocks the underground sewage pipe, it is extremely difficult to dredge it. Suction trucks and high-pressure dredging vehicles cannot dredge it, and auxiliary equipment such as pipe dredging devices are needed to dredge the pipes.

[0003] The existing pipeline dredging device is a pipeline dredging device for water conservancy projects with Chinese patent publication number CN216225951U. The disclosed technology is: a first drive motor drives the first threaded rod to rotate, drives the first threaded block to move forward and backward along the first threaded rod, thereby driving the first cleaning brush and the second cleaning brush to move forward and backward to fully scrape the silt on the inner wall of the pipeline; although the first cleaning brush and the second cleaning brush can scrape and clean the inner wall of the pipeline by moving forward and backward, there is a problem that the inner wall of the pipeline with the same radial direction cannot be scraped and cleaned in a rotating cycle.

DETAILED DESCRIPTION

[0025] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0026] like Figures 1 to 4 shown.

[0027] An underground pipeline dredging and maintenance device of the present application comprises:

[0028] A fixed cylinder 1 is provided as a mounting base for the whole, and the interior of the fixed cylinder 1 is hollow;

[0029] A fixed cover 3 is fixedly installed inside the fixed cylinder 1 through a plurality of spaced fixed plates 17, so that a gap is maintained between the fixed cover 3 and the fixed cylinder 1, so that water with silt can be smoothly discharged outward through the inside of the fixed cylinder 1. Four fixed plates 17 form a group in the same cross section of the fixed cylinder 1;

[0030] A gear ring 7 is rotatably mounted on one end of the right side of the fixed cylinder 1 through a rotary bearing 8. The inner ring of the rotary bearing 8 is fixed to the end of the fixed cylinder 1. The gear ring 7 is fixed to the outer ring of the rotary bearing 8. The gear ring 7 has a meshing tooth structure on its inner diameter surface.

[0031] A rotating motor 4 is fixedly installed in the fixed cover 3. The rotating shaft of the rotating motor 4 can be rotated to extend out of the fixed cover 3 and a rotating gear 6 is installed. The rotating gear 6 is meshed with a planetary gear 18. The planetary gear 18 is meshed with a gear ring 7. The planetary gear 18 is rotatably installed on the inner ring of a rotating bearing 8 in a fixed state through a bearing and a support member, so that the planetary gear 18 can be rotatably installed on the fixed cover 3.

[0032] A cleaning plate 10 is fixedly mounted on the outer circumferential surface of the gear ring 7, and a plurality of cleaning plates 10 are spaced apart and distributed in a circular array.

[0033] When the fixed cylinder 1 is in the underground pipeline, the rotating motor 4 drives the rotating gear 6 through the planetary gear 18 to make the gear ring 7 rotate on the end of the fixed cover 3 based on the rotating bearing 8, and multiple cleaning plates 10 spaced apart in a circumferential array are driven by the gear ring 7 to realize rotational circulation scraping and washing of the same radial inner wall of the pipeline circumference, thereby solving the problem that the same radial inner wall of the pipeline circumference cannot be rotationally scraped and washed.

[0034] The rotating shaft of the rotating motor 4 installed with the rotating gear 6 is fixedly connected with the drill bit 5 through a stabilizing ring 19. The drill bit 5 is fixed to the rotating shaft of the rotating motor 4 through the stabilizing ring 19. The stabilizing ring 19 can increase the connection strength between the rotating motor 4 and the drill bit 5, make the connection between the drill bit 5 and the rotating motor 4 tighter, and ensure the stable operation of the drill bit 5.

[0035] The cleaning plate 10 is fixedly mounted on the outer circumferential surface of the gear ring 7 via the connecting spring 9. The cleaning plate 10 can be extended and retracted based on the connecting spring 9 to contact the inner wall of the pipeline.

[0036] A second telescopic rod 20 is installed in the connecting spring 9 , and two ends of the second telescopic rod 20 are fixedly connected to the cleaning plate 10 and the gear ring 7 , respectively. The cleaning plate 10 performs telescopic movement in the radial direction of the gear ring 7 by means of the telescopic second telescopic rod 20 .

[0037] A water suction pump 2 is installed on the end of the fixed cylinder 1 away from the drill bit 5 through a reinforcement ring 11. The water suction end of the water suction pump 2 is connected to the internal space of the fixed cylinder 1, and the drainage end of the water suction pump 2 is outside the fixed cylinder 1 and connected to a hose 12. A connecting flange 13 is provided on the hose 12. The connecting flange 13 facilitates the connection of the drainage pipe. Through the water suction pump 2 and the hose 12, water containing a large amount of sediment can be smoothly discharged from the internal space of the fixed cylinder 1.

[0038] The outer surface of the fixed cylinder 1 is fixedly installed with roller frames 15 distributed in a circumferential array at intervals. The roller frames 15 are provided with rolling brushes for rolling cleaning. The roller frames 15 are grouped into six on the same circumferential end surface of the fixed cylinder 1. The roller frames 15 are installed on the outer surface of the fixed cylinder 1 in two groups.

[0039] Each of the roller frames 15 is mounted on the fixed cylinder 1 via a retractable first telescopic rod 16, a compression spring 14 is mounted on the outside of the first telescopic rod 16, and both ends of the compression spring 14 are correspondingly fixedly connected to the roller frame 15 and the fixed cylinder 1. When the rolling brush of the roller frame 15 contacts the inner wall of the pipeline, the compression spring 14 and the first telescopic rod 16 are compressed to perform adaptive contact to clean the sludge.

[0040] The working principle is: when in use, first connect the water suction pump 2 and the rotating motor 4 to the power supply. When it is necessary to dredge the underground pipeline, the power provided by the rotating motor 4, in combination with the protection of the fixed cover 3 and the limit of the fixed plate 17, can drive the drill bit 5 to rotate, thereby cleaning the mud and sand inside the underground pipeline, thereby achieving the dredging and cleaning of the underground pipeline. When the blocked mud and sand are mixed into the water body into the fixed cylinder 1, the suction force provided by the water suction pump 2 can be formed inside the fixed cylinder 1, so that the water mixed with a large amount of mud and sand can be sucked out through the gap between the fixed cylinder 1 and the fixed cover 3, so that the cleaned mud and sand can be better discharged outward. , preventing sediment from flowing downstream with the water flow in the pipeline, greatly increasing the cleaning and dredging effect of the underground pipeline, preventing sediment from forming a blockage again downstream, and, when the rotating motor 4 rotates, it can drive the rotating gear 6 to rotate, and then utilize the meshing relationship between the rotating gear 6 and the planetary gear 18 to cooperate with the auxiliary limit of the rotating bearing 8 to drive the gear ring 7 to rotate, and then utilize the limit of the second telescopic rod 20 to drive the connecting spring 9 and the cleaning plate 10 to rotate, the elastic force provided by the connecting spring 9 can push the cleaning plate 10 to always keep in contact with the inner wall of the underground pipeline, and then can clean the inner wall of the underground pipeline, further increasing the dredging and maintenance effect of the underground pipeline.
