Photovoltaic power generation apparatus capable of automatically tracking sun direction

Abstract

The invention discloses a photovoltaic generation device capable of automatic tracking sun position comprising a sun time-angle tracking unit, an array inclination angle regulating unit, a photovoltaic cell fixedly connected to the upper frame and bearings with holders on the bottom front frame and a motor arranged on a connector on top of the photovoltaic cell, wherein the motor brings along the connector and the photovoltaic cell rotating coaxially under the signal drive, at the same time the left and right sides of the photovoltaic cell are supported by two side frames with a linkage beam connecting to the lower end, a lead screw is crossed between the bottom front frame and the bottom back frame of the bottom frame, when the lead screw rotates under the external motive power action, the linkage beam connected to the lead screw shifts along the sliding guideway, the frames stands or lay down thereupon and the inclination angle of the photovoltaic cell changes correspondingly. The device of the invention can real-timely regulates the rotation angle and inclination angle, has advantages of low cost, easy to expand, simple structure and high control precision.

Description

technical field [0001] The invention relates to the field of solar photovoltaic power generation, in particular to an expandable photovoltaic power generation device that automatically tracks the orientation of the sun. Background technique [0002] As a huge amount of renewable energy, solar energy reaches the surface of the earth every day, which is equivalent to the energy of burning trillions of barrels of oil. The most notable advantage of developing and utilizing abundant solar energy resources is that there is no pollution or only a small amount of pollution to the environment. Therefore, solar energy is not only an urgently needed supplementary energy in the near future, but also the basis of the future energy structure. It is estimated that by the middle of this century, solar photovoltaic power generation will become one of the basic energy sources for human beings. The biggest problem at present is that the investment in power generation equipment is too high and...

Problems solved by technology

The transmission method of the device adopts electric transmission, and the precision can be made very high, but the energy consumption is high and the cost is also high; the patent application number is 200610088177.7 and the name is "Planar Grid Frame Two-dimensional Sun Tracking Photovoltaic Power Generation Device" In the application, a tracking device using a mechanical transmission method is disclosed. The planar grid frame equipped with solar panels is mainly hinged on the horizontal axis and the vertical axis, and the two-dimensional rotation is realized through the rollers. The tracking drive mechanism is simple, but due to The rollers are installed under the plane support. When rotating horizontally, the whole device will be driven to rotate along the ground track, which consumes a lot of power.

[0005] The above-mentioned existing technologies have certain application value, but the current tracking device still has disadvantages such as high cost, high power consumption and poor scalability, which need further improvement
