Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipes, in particular to a dredging device for urban pipe water supply and drainage. Background Technique

[0002] A drain pipe is an urban public facility that has appeared since ancient Roman times. The prototype of modern sewers originated in Paris, France, and Paris still has the largest urban sewer system in the world. Generally speaking, the sewer system is used to collect and discharge domestic wastewater generated in cities and industrial wastewater generated in industrial production. However, during long-term use, it is inevitable that the pipeline will accumulate and become blocked, resulting in abnormal drainage of the pipeline. Generally, a dredging device is used for dredging.

[0003] Since the dredging device often encounters pipes with different diameters during use, and the existing dredging device is not convenient to adjust according to the pipe diameter, the staff often needs to replace different dredging heads, resulting in inconvenient operation and low dredging efficiency. For this reason, we propose a dredging device for urban pipe water supply and drainage to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a dredging device for urban pipe water supply and drainage to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A dredging device for urban pipe water supply and drainage includes a protection box. The upper surface of the protection box is fixedly inlaid with a sealed bearing. The inner ring of the sealed bearing is fixedly connected with a threaded rod. The outer surface of the threaded rod is slidably connected with a limit ring. The outer surface of the limit ring is fixedly connected with a pair of symmetric first limit blocks. The inner parts of the two first limit blocks are both movably connected with limit rods through pins. The other ends of the two limit rods are both movably connected with second limit blocks through pins. The outer surfaces of the two second limit blocks are both fixedly connected with connecting rods. The top end of the threaded rod is fixedly connected with a punch head. The bottom surface of the punch head is fixedly connected with a pair of symmetric fixing blocks. The two fixing blocks are both movably connected with the connecting rods through pins. The outer surfaces of the two connecting rods are both fixedly connected with baffle plates. The bottom surface of the protection box is fixedly connected with a water inlet box. The inner wall of the water inlet box is provided with a water outlet. The outer surface of the water inlet box is fixedly connected with a water outlet chamber.

[0007] In a further embodiment, a rotating motor is arranged inside the protection box, and the output end of the rotating motor is connected with the inner ring of the sealed bearing.

[0008] In a further embodiment, a plurality of blades are fixedly connected to the outer surfaces of the two baffle plates.

[0009] In a further embodiment, a spring is sleeved on the outer surface of the threaded rod. The bottom end of the spring is connected to the upper surface of the limit ring, and the top end of the spring is connected to the bottom surface of the punch.

[0010] In a further embodiment, a limit nut is threadedly connected to the outer surface of the threaded rod, and the limit nut is in contact with the limit ring.

[0011] In a further embodiment, a connecting head is fixedly connected to the bottom surface of the water inlet tank, and a thread is provided on the outer surface of the connecting head.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: By sliding the limit ring to drive the limit rod to expand, the expansion of the limit rod is used to drive the connecting rod and the baffle to expand at the same time, and the diameter of the device is adjusted to adapt to the pipeline. When the baffle expands to the designated position, the limit nut is rotated to abut against the limit ring, so that the limit rod can be fixed to the designated position. By rotating the limit nut and using the automatic reset function of the spring, the limit ring is automatically reset. By starting the rotary motor to drive the threaded rod to rotate, the rotation of the punch is used to drive the baffle and the blade to rotate, so as to cut the blockage.
