Description

Technical Field

[0001] The utility model belongs to the technical field of inspection devices, in particular to a long-distance water pipeline valve well inspection device. Background Art

[0002] When the operator is inspecting the valve well of the water supply pipeline, the operator opens the manhole cover of the valve well. After the manhole cover is opened, the operator observes whether the pipeline in the valve well is broken, deformed, leaking or water is accumulated. However, since the valve well is generally deep, the inside of the valve well may be dim. When observing the pipeline, the operator may carry a flashlight and shine the light generated by the flashlight on the pipeline to observe the surface of the pipeline. However, since the operator may need to use both hands to operate in the valve well, when performing two-handed operation, the operator holds the flashlight in one hand, which may make the operator unable to operate with both hands. For this reason, we propose a long-distance water supply pipeline valve well inspection device. Utility Model Content

[0007] Furthermore, the avoidance grooves are all configured as arc-shaped grooves, and the fixing plates are all configured as arc-shaped plates that match the avoidance grooves.

[0008] Furthermore, a traction rod is fixed on one side of the first connecting block and the second connecting block that are in contact with each other, and the traction rod passes through the second connecting block. A connecting plate is fixed at the end of the traction rod, and a spring is wrapped around the surface of the traction rod, and the ends of the spring are respectively abutted between the connecting plate and the surface of the first connecting block.

[0009] Furthermore, a positioning rod is fixed on one side where the first connecting block and the fixed block are fitted together, and the surface of the positioning rod is provided with a mounting groove provided on the fixed block, and the surface of the mounting groove is fitted with a cover plate rotatably connected to the fixed block.

After the elastic deformation of the spring is restored, the spring pulls the traction rod to move through the connecting plate, and the traction rod drives the first splint to move through the second connecting block, so that the first splint and the second splint clamp the flashlight.

Traction grooves 6 are welded to the ends of the second splint 5 and the first splint 4. When the operator needs to clamp the flashlight on the safety helmet 1, the operator takes the flashlight, aligns the flashlight with the two sets of traction grooves 6, and pushes the flashlight so that the surface of the flashlight fits the traction grooves 6. Then the operator pushes the flashlight to move, and the surface of the flashlight is pressed against the surface of the traction grooves 6. The flashlight pushes the first splint 4 to move through the traction grooves 6, and the first splint 4 is in the When moving, the first splint 4 drives the second connecting block 3 to move, and the second connecting block 3 drives the traction rod 12 to slide in the through hole opened in the first connecting block 2, and when the traction rod 12 moves, the traction rod 12 drives the connecting plate 13 to move, so that the connecting plate 13 squeezes the spring 14, causing the spring 14 to undergo elastic deformation. After the spring 14 undergoes elastic deformation, the spring 14 avoids the traction rod 12, so that the first connecting block 2 is separated from the second connecting block 3, and the first splint 4 and the second splint 5 are opened. When the first splint 4 and the second splint 5 are opened, the first splint 4 and the second splint 5 are on opposite sides. The flashlight avoids, and then the operator pushes the flashlight into the gap between the first splint 4 and the second splint 5. When the flashlight no longer pulls the first splint 4 through the traction groove 6, the first splint 4 no longer drives the connecting plate 13 to squeeze the spring 14 through the second connecting block 3, and the spring 14 elastically recovers. The spring 14 pushes the traction rod 12 to move through the connecting plate 13, and the traction rod 12 drives the first splint 4 to move through the second connecting block 3, so that the first splint 4 and the second splint 5 clamp the flashlight, which is convenient for the operator to store the flashlight and improves the operator's usability.
