Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, in particular to a maintenance device for municipal pipelines. Background Art

[0002] Municipal engineering is an important guarantee for the construction of urban material and spiritual civilization. It is mainly composed of various engineering systems such as transportation, water supply, drainage, gas, and landscaping. Among them, gas provides the necessary guarantee conditions for the normal work and life of citizens. Natural gas pipelines are the main way to transport urban gas, so municipal gas pipelines need to be inspected and maintained regularly.

[0003] Endoscopes are often used in pipeline maintenance. That is, a flexible spring tube is used in conjunction with a camera to view the inside of the pipeline. The existing maintenance device does not have a limit structure on the camera when in use, which makes the camera easy to shake inside the pipeline, or even collide and cause damage. In addition, the camera is easily affected by dust and impurities inside the pipeline, which reduces the clarity of the shot and affects actual use. Utility Model Content

Specific implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-5 , the present invention provides a technical solution: a maintenance device for municipal pipelines, including a maintenance cylinder 1. One end of the maintenance cylinder 1 is fixedly welded to the telescopic hose 2. The telescopic hose 2 is a telescopic corrugated pipe. One end of the telescopic hose 2 is fixedly welded to the connecting cylinder 3. The outer side of the maintenance cylinder 1 is rotatably connected to the gear ring 4. The outer side of the maintenance cylinder 1 is fixedly connected to the motor 1 5 through bolts. The output end of the motor 1 5 is fixedly welded to the driving gear 6. The driving gear 6 is meshed with the gear ring 4. The outer side of the maintenance cylinder 1 is fixedly welded to the side plate 7. The side plate 7 is rotatably connected to one end of the connecting shaft 8. The other end of the connecting shaft 8 extends to one side of the side plate 7 and is fixedly welded to the driven gear 9. The driven gear 9 is meshed with the gear ring 4. The outer side of the connecting shaft 8 is fixedly welded to one end of the sleeve 10. The inside of the sleeve 10 is slidably connected to the telescopic rod 11. One end of the telescopic rod 11 is provided with a ball 12. The surface of the ball 12 is smoothly arranged. A spring 13 is sleeved inside the sleeve 10. The outer side of the maintenance cylinder 1 is fixedly connected to the motor 2 14 through bolts. The output end of the motor 2 14 is fixedly welded to the rotating plate 15. One end of the maintenance cylinder 1 is provided with a cleaning plate 16. The side of the cleaning plate 16 is provided with cleaning cotton. The cleaning plate 16 is rotatably connected to one end of the hinge shaft 17. A chute 18 is opened on the surface of the cleaning plate 16. One end of the maintenance cylinder 1 is provided with a camera 19. A plurality of lighting lamps are arranged on the same side of the camera 19. Both the camera 19 and the lighting lamps are located inside the mirror surface 20. One end of the maintenance cylinder 1 is fixedly welded to the mirror surface 20. The mirror surface 20 is made of a transparent material.

[0022] In order to enhance the stability of the limit of the maintenance cylinder 1, the number of the driven gears 9 and the sleeves 10 is the same, and they are both arranged in a circumferential array around the center of the maintenance cylinder 1. In addition, the driven gears 9 are evenly meshed with the gear ring 4. In this way, the rotation of the gear ring 4 can simultaneously drive several sleeves 10 to rotate synchronously, realizing the limit fixation of pipelines with different inner diameter sizes and reducing the difficulty of adjustment.

[0023] The toothed ring 4 is simultaneously meshed and connected with the driving gear 6 and the driven gear 9. The outer side of the connecting shaft 8 is fixedly welded to one end of the sleeve 10 through a connecting block. The driving gear 6 is driven by the first motor 5 to drive the toothed ring 4 to rotate, so that the driven gear 9 rotates synchronously. Further, the sleeve 10 is driven by the driven gear 9 to rotate synchronously until the ball 12 is attached to the inner wall of the pipeline.

[0024] To prevent the maintenance cylinder 1 from being blocked by the attachments on the inner wall when moving inside the pipeline, the telescopic rod 11 is slidably connected to the inside of the sleeve 10. When the ball 12 encounters an obstacle, it will push the telescopic rod 11 to move inside the sleeve 10 to ensure the smooth movement of the maintenance cylinder 1. The elastic force of the spring 13 is used to make the ball 12 closely attached to the inner wall of the pipeline.

[0025] The sleeve 10 is slidably connected to the outer side of the telescopic rod 11 through a circular through-hole. One end of the telescopic rod 11 is fixedly welded to the limiting plate. The inside of the sleeve 10 is slidably connected to the limiting plate. One side of the rotating plate 15 is fixedly welded to one end of the sliding rod. The inside of the sliding groove 18 is slidably connected to the outer side of the sliding rod. The sliding groove 18 is located at the top of the cleaning plate 16. One end of the hinge shaft 17 is fixedly welded to the maintenance cylinder 1. The cleaning plate 16 is movably hinged to the maintenance cylinder 1 through the hinge shaft 17.

[0026] Working principle: When in use, the staff places the maintenance cylinder 1 inside the pipeline to be maintained. The driving gear 6 is driven by the first motor 5 to drive the toothed ring 4 to rotate. The rotation of the toothed ring 4 will cause several driven gears 9 to rotate synchronously. Further, the sleeve 10 is driven by the driven gear 9 to rotate synchronously until the ball 12 is attached to the inner wall of the pipeline. The maintenance cylinder 1 is supported and limited by the sleeve 10 and the telescopic rod 11 to prevent the maintenance cylinder 1 from colliding with the inner wall when moving inside the pipeline. When the mirror surface 20 is contaminated, the rotating plate 15 is rotated by the second motor 14, so that the rotating plate 15 drives the sliding rod to make a circular motion. The sliding rod slides inside the sliding groove 18 at the same time, and further drives the cleaning plate 16 to swing reciprocally with the hinge shaft 17 as the center, and the mirror surface 20 is cleaned by the cleaning plate 16 to ensure the clarity of the camera 19 shooting.
