Small wind driven generator with stable transmission structure

Abstract

According to the small-sized wind driven generator with the stable transmission structure, blades are connected with the front end of a main shaft, and the main shaft passes through a shell and is connected to a first transmission rod through a bevel gear; the spring energy storage structure is fixed to the first transmission rod and connected to the second transmission rod through a straight gear, and the second transmission rod is connected with the first fixing rod through a bearing and fixedly supported by the first fixing rod. The stable speed regulation structure is installed on the second transmission rod, connected with the third transmission rod through a straight gear and finally connected with the generator through a third bevel gear, and an electrical cabinet is fixed through a shell; the spring energy storage structure and the stable speed regulation structure jointly form a stable transmission structure, when wind power is too large, excessive wind energy is stored, when the wind power is too small, the stored wind energy is released, stable transmission is achieved through the stable speed regulation structure, it is guaranteed that the wind driven generator operates at the stable rotating speed all the time, and the service life of the wind driven generator is prolonged. And furthermore, alternating current with stable voltage is generated.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a small wind power generator with a stable transmission structure. Background technique [0002] Faced with the dilemma of the decreasing number of non-renewable energy sources, people have increased their investment in new energy development. Wind power is a kind of green and renewable energy, especially my country has abundant wind energy resources. Therefore, increasing investment in the development of wind power industry will help alleviate the growing energy crisis. [0003] Small wind turbines can make full use of widely distributed wind energy resources, and gradually attract people's attention. Whether in mountainous areas or cities, on the roof or in open spaces, small wind turbines can be used to convert wind energy into electrical energy and store it for daily lighting and charging of small and medium-sized electronic products, which not only saves elect...

Problems solved by technology

[0004] However, under the existing technical conditions, due to the uncontrollability and randomness of the wind force of the natural wind, the uncertainty of the speed of the wind generator is caused, so that the voltage and frequency of the alternating current generated by the alternator are not stable enough, so The alternating current needs to be further processed to become an alternating current with a stable voltage before it can be connected to the grid for users to use. This not only causes unnecessary loss of electric energy, reduces the conversion efficiency of wind energy, but also increases the utilization cost of wind power generation.
