Description

Technical Field

[0001] This utility model relates to a wind power generator, and more particularly to a small wind power generator that is mounted on a street light, including a wind power generator, a connecting pipe body, and a fixing device. Background Technology

[0002] As we all know, wind power is a way of generating electricity by converting wind energy into mechanical energy. Wind power captures wind energy through a wind turbine, which drives the blades to rotate. A speed increaser increases the rotation speed and then drives the motor to generate electricity. Wind power has many advantages such as being green and environmentally friendly and having low cost.

[0003] Wind power generators are particularly suitable for use in streetlights, and this adaptation method has been widely applied in streetlights in coastal and remote areas.

[0004] For streetlights that were installed in the early stages, especially those in coastal or remote areas, if wind turbines need to be added, the original streetlights often need to be removed first, and then new streetlights with wind power generation capabilities need to be installed. This replacement method is costly and not suitable for widespread application. Currently, there are no wind turbines that can be installed on existing streetlights, which is the main drawback of the existing technology. Utility Model Content

A bearing is disposed in the upper bearing cavity, and the bottom insertion shaft is inserted into the bearing. The fixing device is inserted into the lower insertion cavity of the connecting pipe body. The fixing device includes a top plate, an upper adjusting plate, an assembly rod, and a lower adjusting plate. The top plate includes a boss and a limiting plate. The boss protrudes from the center of the limiting plate and is detachably inserted into... In the lower insertion cavity of the connecting pipe body, the limiting plate has a limiting ring body, which is arranged around the limiting plate. The bottom of the connecting pipe body is pressed against the top of the limiting ring body. The upper adjusting plate is fixedly connected to the bottom of the limiting plate.

The upper bolt holes and lower bolt holes are respectively opened at the upper and lower ends of the rod body. The lower adjusting plate is provided with several lower stop slots. The upper and lower ends of the assembly rod are respectively fixed in the upper stop slots of the upper adjusting plate and the lower stop slots of the lower adjusting plate by assembly bolts. The front end of the lower adjusting plate is provided with a connecting welding claw.

[0006] The beneficial effects of this utility model are as follows: When using this utility model, firstly, the connecting welding claw is pre-fixed on the street light pole, and then the lower adjustment plate is fixed to the street light pole as a whole by welding. Then, the upper adjustment plate is fixed above the lower adjustment plate by the assembly rod, and the relative position of the upper adjustment plate and the lower adjustment plate is adjusted by the assembly position of the assembly rod. Then, the connecting pipe body is inserted into the boss body of the fixing device. Finally, the bottom insertion shaft of the wind turbine is inserted into the bearing of the connecting pipe body. The bottom insertion shaft can rotate in the bearing, so that the wind turbine can rotate the blades to generate electricity according to the wind direction. This utility model is mainly used for the modification of street lights to enable the street lights to have the function of wind power generation. This utility model has the characteristics of low cost and easy assembly. The structural design of the upper adjustment plate, the assembly rod and the lower adjustment plate of this utility model can facilitate installation and adjust and fix the position relationship of each component according to specific conditions.
