Description

Technical Field

[0001] This utility model relates to the field of water conservancy pipeline technology, and more specifically, to a water conservancy pipeline docking and guiding device. Background Technology

[0002] Water conservancy pipelines, also known as water conveyance channels, are a general term for pipes and channels that transport water from a long-distance water source to a point of use. In a broad sense, it refers to the entire long-distance water conveyance system, including pipes, open channels, culverts, and tunnels. In a narrow sense, it refers only to water conveyance structures that cross valleys, river valleys, or low-lying areas. The pipe material depends on the pipe diameter and water pressure. For no pressure or low pressure, concrete or low-pressure reinforced concrete pipes are generally used, while for high pressure, reinforced concrete pipes, cast iron pipes, or steel pipes are used. When constructing water conservancy projects, it is necessary to lay underground pipelines to transport water resources, control water flow, prevent floods, and regulate and distribute water to meet the needs of people's lives and production. However, during the construction process, multiple sets of pipelines need to be connected when laying the pipelines.

[0003] In the prior art, application number 202420542277.6 discloses a water conservancy pipeline docking guide device, including a base, a ball screw connected inside the base, a ball screw sleeve connected to the ball screw, and a movable plate fixedly connected to the upper end of the ball screw sleeve. Adjusting rods are inserted into both the left and right ends of the movable plate, and adjusting blocks are connected to the other ends of the adjusting rods. A placement plate is fixedly connected to the upper end of the adjusting block, and a baffle is fixedly connected to the upper end of the placement plate. The above device completes the front and rear docking of the pipeline and the lateral support of the pipeline size through multiple sets of screws. The daily maintenance of the screws is cumbersome. Wear on the threads on the surface of the screws will reduce the smoothness of the adjustment operation. Moreover, it can only perform simple docking and support. It requires the staff to manually adjust the position of the pipeline to be docked on the placement plate. Repeated dragging will cause friction damage to the pipeline.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
