Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to an auxiliary alignment device for wind power generation installation. Background Art

[0002] A wind turbine is a device that converts wind energy into electrical energy. It is mainly composed of a wind rotor, a generator, a tower and other components. The wind rotor is the core part of the wind turbine and is usually composed of multiple blades. The blades rotate under the action of wind, converting the kinetic energy of the wind into the mechanical energy of the wind rotor shaft. The generator uses the mechanical energy driven by the wind rotor shaft to generate electrical energy. Usually, an AC generator is used. The tower is used to support the wind rotor and the generator, and they are installed at a high place to better utilize wind energy. The working principle of the wind turbine is relatively simple. When the blades are affected by wind, they will start to rotate, thereby driving the wind rotor shaft to rotate. The rotation of the wind rotor shaft is transmitted to the generator through the transmission chain, and the generator uses the relative movement of the magnetic field and the wire to generate electrical energy. The generated electrical energy is processed by the converter and transformer and finally transmitted to the power system.

[0003] The convenient wind power generation device with the public number CN219176490U relates to the field of wind power generation, including a combined wind power generation component. The convenient wind power generation device described in the utility model includes a column, a mounting ring, a fixing groove, a generator cabin, a blade corrector and a detachable blade through the set combined wind power generation component, which can be disassembled and stored when in use to improve the portability of the device and make it have better convenient installation. The convenient installation component includes a fixing ring, a screw rod, a mounting nut, a threaded rod and a ground nail. When in use, the ground nail is first passed through the fixing ring. When in use, the wind power generation device can be quickly installed and fixed, and it has better installation stability. This device is not only simple in structure, but also easy to operate, bringing better use prospects. However, in this scheme, the installation between the columns during the installation process is more troublesome, and multiple attempts are required, which affects the work efficiency. For this reason, we propose a wind power generation installation auxiliary alignment device. Utility Model Content

The empty slots are arranged on the upper surface of the first column section, leaving a certain distance between the empty slots and the clip-on structure. The fixing column 12 is installed below the second column section 2 and inserted into the empty slots on the upper surface of the first column section 1.

[0027] Furthermore, the exposed portion of the fixing column 12 is shorter than the exposed portion of the clip 8, and the clip 8 is moved and aligned inside the semicircular groove 9 above the first column section 1. When the clip 8 moves to the center, it enters the inside of the slot 10. At this time, the fixing is aligned with the clip 8 to the inside of the empty groove above the first column section.

[0028] Furthermore, the upper part of the clamping structure includes a fixed block 7 and a clamping plate 8, the fixed block 7 is installed on the lower surface of the second column section 2, the clamping plate 8 is installed inside the fixed block 7, and the lower end of the clamping plate 8 protrudes from the lower surface of the fixed block 7, thus forming the upper part of the clamping structure.
