[0001] This utility model relates to the field of power engineering equipment, and in particular to a cable winding and unwinding device for power engineering surveying. Background Technology

[0002] Power engineering survey refers to a series of investigation, research and technical evaluation activities carried out before the start of a power engineering project in order to ensure the safety, economy and reliability of the project's design, construction and subsequent operation. This process covers a comprehensive investigation of multiple aspects, from the natural geographical environment to the distribution of underground facilities, and is an important basic link in the planning and construction of power engineering.

[0003] In the process of surveying, construction and maintenance of power engineering, cable laying and retrieval is a common and important task. Traditional cable laying and retrieval methods mostly rely on manual operation or simple mechanical assistance. This method cannot effectively guide the cables and cannot ensure that the cables enter and exit along the predetermined path, thus affecting work efficiency. Utility Model Content

The first threaded shaft passes through the placement block and is threadedly connected to the first fixing block. The first threaded cap is connected to the other end of the first threaded shaft.

[0007] Furthermore, a telescopic rod is fixed to one side of the base plate, and a control knob is installed on the telescopic rod, with the guide mechanism installed at the top of the telescopic rod.

[0008] Furthermore, it also includes a support plate, a rotating shaft, and a fixed plate, and the support plate, rotating shaft, and fixed plate are all arranged in pairs. The support plate is fixedly connected to the surface of the base plate, and the top of the support plate has a rectangular groove.
