Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a wind power generation support structure. Background Art

[0002] Wind power generation refers to the conversion of wind's kinetic energy into electrical energy. Wind energy is a clean, pollution-free, renewable energy source that has been used for a long time, primarily through windmills for pumping water and grinding flour. People are now more interested in using wind to generate electricity. Large wind turbines consist of a support frame and a generator impeller, and are often shaped like a large windmill.

[0003] In the prior art, Chinese utility model application number CN202220358555.3 discloses a wind turbine support frame, comprising a column, a connecting frame, a motor, a first positioning plate, a spring, and a second positioning plate. The second positioning plate is disposed on the outside of the column, the first positioning plate is disposed on one side of the second positioning plate, the connecting frame is disposed on one side of the first positioning plate, and the motor is disposed on the upper end of the column. This utility model provides a stable and buffering support effect, solving the problem of existing wind turbine support frames lacking a stable support effect. In windy weather, the lateral wind force brings an impact force to the power generation device, causing the device to easily tilt and cause accidents.

[0004] Although the above technical solution can reduce the impact force of lateral wind, the current support structure needs to be installed and fixed by digging a pit on the ground, then placing the chassis in the pit and pouring concrete to fix it. However, before the concrete is dry and fixed, the center of gravity of the power generator base is unstable and it will fall over, causing the concrete to crack and cause waste, and the power generator base is prone to tilting and accidents. Therefore, we need to propose a wind power generation support structure. Utility Model Content
