Description

Technical Field

[0002] Electrical engineering is an important sub-project of wind farm installation engineering. Its success or failure is related to the progress, acceptance and use of the entire single project. Compared with other industrial electrical installation and civil electrical installation projects, wind farm electrical construction has some characteristics: wind farms are mostly located in wild places such as the seaside, grasslands, hills, and Gobi, with difficult conditions and harsh environment, which brings many inconveniences to construction. The foundation of a fan is usually a large concrete foundation with a large number of pre-buried wire pipes for electrical instruments in the foundation. PVC wire pipes are generally used, and the right-angle joints of the wire pipes generally use elbows with larger arcs. This requires the staff to pre-bend the ends of the wire pipes in advance. In existing construction, the staff generally bend the wire pipes directly with their bare hands or with the help of the ground. The disadvantages of this bending wire pipe are: 1. It is time-consuming and labor-intensive, and the different bending angles of the wire pipes will affect the normal laying of the lines and cause unsightly construction sites; 2. It is easy to cause wear on the outer wall of the pipeline; 3. When the wire pipe is bent, the bend is prone to deformation; so now there is an urgent need for a tool that can quickly bend the ends of the wire pipes without damaging the wire pipes.
