[0002] A wind turbine is a system that converts the kinetic energy of wind into electrical energy. A wind turbine includes a wind rotor and a generator. The wind rotor contains blades, a hub, reinforcements, etc. It has the functions of generating electricity by the blades rotating under wind force and the generator head rotating. The wind power supply consists of a wind turbine, a tower supporting the turbine, a battery charging controller, an inverter, an unloader, a grid connection controller, a battery pack, etc. In order to remind the staff when a wind turbine fails, it needs to be used in conjunction with the wind turbine fault alarm device.

[0003] The wind turbine generator set fault alarm device needs to be installed on the wind turbine generator set. For example, Chinese utility model patent CN219492482U discloses a wind turbine generator set fault alarm device. The wind turbine generator set fault alarm device is placed in the corresponding working position, and then the various components of the wind turbine generator set fault alarm device are checked to see if they are working properly. After the inspection is completed, the wind turbine generator set fault alarm device is electrically connected to the external power supply. After the connection is completed, it can be used. When in use, the output shafts of the two forward and reverse servo motors set by the forward and reverse servo motor control switch on the switch panel rotate to drive the two shafts to rotate, and the rotation of the two shafts drives the two The gears rotate, and the two gears rotate to drive the two circular grooves to rotate by meshing with the corresponding inner gear rings. The rotation of the two circular grooves drives the mounting plate and four screws to rotate through the inverted U-shaped frame. The mounting plate and the four screws are controlled to rotate to the corresponding installation angles, which is convenient for better installation and fixation on the mounting surfaces at different angles. The mounting plate is fixed to the corresponding working position by four screws. After the installation is completed, the power fault alarm body is connected to the external monitored equipment. The output shaft of the drive motor is controlled to rotate through the drive motor control switch on the switch panel to drive the fan blades to rotate. The fan blades are controlled to rotate to ventilate, dissipate heat and cool the power fault alarm body.

[0004] Although the above-mentioned prior art can conveniently install the alarm device, the mounting plate can only be rotated in a semicircle around the alarm device during installation. If the installation position is extremely complex and out of the adjustment path of the mounting plate, it cannot be installed, so the installation application range is limited.
