Description

Technical Field

[0001] The utility model relates to the technical field of fan installation structures, in particular to an installation structure of a fan foundation anchor bolt and an anchor plate. Background Art

[0002] With the increase in population, energy and environment have become two major problems facing people. On the one hand, the continuous consumption of traditional fossil fuels has prompted people to seek new energy as an alternative. On the other hand, traditional fossil fuels will cause air pollution and increase carbon dioxide content, causing the greenhouse effect. Wind power generation is clean and pollution-free, has a large single-unit capacity, and has good economic and social benefits. It is one of the most promising new energy sources. When the wind turbine is running, the alternating loads such as aerodynamic force, inertial force and elastic force acting on the blades are transmitted to the foundation through the tower, making the force on the foundation very complex. The wind turbine foundation is an important supporting structure of the wind turbine.

[0003] When installing the existing wind turbine foundation anchor bolts and anchor plates, it is necessary to use a crane to lift the upper anchor plate and manually fix the anchor bolts. When installing it, the staff needs to put their hands under the lower anchor plate and then use nuts to fix the anchor bolts. However, this method requires the staff to squat back and forth, which causes great damage to the staff's lumbar spine, and squatting for a long time can easily make the staff's legs and feet numb. If the lifting rope breaks or the anchor bolt falls, the staff may not be able to evacuate the scene in time, resulting in accidents. Therefore, we propose an installation structure for wind turbine foundation anchor bolts and anchor plates. Utility Model Content
