Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology, and in particular to a pipeline inner wall cleaning device. Background Technology

[0002] An existing device, CN 221361703 U, describes an inner wall cleaning device for polyurethane insulated pipes. This device uses a motor output to drive a transmission rod, sliding rod, hollow rod, second hydraulic rod, and cleaning plate to rotate. The rotating cleaning plate cleans the inner wall of the polyurethane insulated pipe. The transmission rod's rotation drives a belt and a reciprocating screw to rotate, causing the moving plate, hollow rod, second hydraulic rod, and cleaning plate to move left and right simultaneously. This simultaneous rotation and movement of the cleaning plate allows for comprehensive cleaning of the inner wall of the polyurethane insulated pipe, and the movement of the cleaning plate also removes the cleaned impurities. However, the reciprocating screw in this device has a large span when supporting the overall movement, resulting in poor overall operational stability. Utility Model Content

A support mechanism for supporting the pipe inner wall is provided on the cylinder, and a cleaning mechanism is provided at the other end of the cylinder. The support mechanism includes a support rod connected to the connecting grooves. A connecting shaft is provided at the end of the support rod away from the cylinder. A support wheel is provided on the connecting shaft. An adjusting rod is connected to the support rod. A connecting plate is connected to one end of the adjusting rod. An electric telescopic rod is connected to the center of the connecting plate and is fixed inside the cylinder. The cleaning mechanism includes a motor installed inside the cylinder. A rotating shaft is connected to the output end of the motor. A rotating cover is fixed at one end of the rotating shaft extending out of the cylinder. Cleaning components are evenly distributed circumferentially on the rotating cover. Each cleaning component includes a movable rod radially passing through the rotating cover. A scraper is provided at the outer end of the movable rod. A support is fixed at the center of the rotating cover, and a spring is provided between the support and the movable rod.

[0006] Further details: The cylinder body has a slot through which the adjusting rod passes, and the support rod and the connecting slot are rotatably connected by a pin. Two support rods are installed in each connecting slot.

[0010] Further details: The two ends of the spring are fixedly connected to the movable rod and the support, respectively, and a cover is provided at the end of the rotating cover away from the rotating shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] By setting up support and cleaning mechanisms on the cylinder, the electric telescopic rod extends and retracts, driving the adjusting rod on the connecting plate. The adjusting rod then adjusts the angle between the support rod and the cylinder, and the support wheel connected to the end of the support rod is held against the inner wall of the pipe to support the whole structure.
