AI Technical Summary
In existing technologies, the process of connecting water conservancy pipelines involves heavy workloads for workers, low work efficiency, poor connection stability, and difficulty in controlling the insertion length of drainage pipes.
It adopts a combination design of support base, limiting part, support ring, docking part and driving component. The driving component controls the synchronous movement of the docking part, so that the drain pipe is inserted into the joint pipe to achieve automatic docking. The guide groove and clamping airbag are used to improve stability.
This reduces the workload of staff, improves work efficiency, and ensures consistent insertion length of drainage pipes, thus enhancing docking stability.
