Embodiment 1

[0043] like figure 1 , 3, 5, 7, and 13 show a kind of Tai Chi gossip type photovoltaic power generation device with a counterweight, mainly comprising a sunlight receiver 1, a sunlight tracking device, a cement seat 6 and a support frame 2; the sunlight receiving The device 1 includes a solar silicon wafer and light superimposing receiving device; the light superimposing reflecting device consists of a light superimposing reflector 11 coaxially stacking light superimposing reflector groups 12, 13 with gradually larger β angles, that is, β<β1<β2; One layer of light superposition mirror 11 is continuously arranged into a gossip-shaped structure by 8 trapezoidal plane mirror units, each trapezoidal plane mirror unit 111 is connected with the second layer of light superposition mirror 12 and the third layer of light superposition mirror 13 A plane reflector unit X corresponds to a row of plane reflector unit groups 1', and two adjacent columns of reflector unit groups 1' are prov...

Embodiment 2

[0052] like Figure 9 , 13 As shown, the light superimposition reflection device in Embodiment 1 can also be a ring structure formed by coaxially stacking five layers of light superposition mirrors. The included angle between the mirror unit and the center line of the light superimposing mirror increases gradually. The first layer of light superimposing mirror consists of 8 trapezoidal plane mirror units continuously arranged in a gossip-shaped structure, and each trapezoidal plane mirror unit is connected to the second A piece of plane mirror unit X from the layer light stacking mirror to the last layer of light stacking mirror corresponds to and arranges a row of plane mirror unit groups, and from the third layer onwards, two adjacent columns of reflection unit groups are arranged on the corresponding mirror layer A piece of plane mirror unit Y, the plane mirror unit X is rectangular, the plane mirror unit Y corresponding to the third layer is trapezoidal, and the fourth la...

Embodiment 3

[0054] like Figure 13 As shown, the tracking device in Embodiment 1 is also applicable to flat-panel solar receivers, that is, the light superimposing and reflecting device is a flat-panel solar chip 9, and the flat-panel solar photovoltaic power generation system that directly receives sunlight does not need to cool down.

[0055] The tracking device of the present invention is also applicable to other solar receiving devices such as a reflecting device composed of five layers of coaxially stacked cones.

[0056] Emphasis of the present invention just lies in:

[0057] like Image 6 shown, 8 1 to 8 2 When the sunlight is reflected by the plane reflector unit and is projected on the solar wafer, the blank A may appear in the horizontal direction or the vertical direction. For this reason, the present invention sets up the plane reflector unit respectively by columns to overcome the horizontal blank, and to overcome the vertical gap by layer distribution. Blank, so that th...

Abstract

Under the illumination of the ancient Taiji eight trigrams of China, the invention provides a Taiji eight trigrams type photovoltaic power generation device with a balance weight, which comprises: an optical superposition reflecting device and a device for carrying out 24-hour automatic tracking to the sun; and realizes that: the power generation capacity of a solar chip is improved by more than 8 to 10 times. The working temperature of the chip is below 60 DEG C. Power supply to the device is self-realized by the device and the power consumption only occupies 3 to 5 percent of the self powergeneration quantity. The device mainly comprises the following technical proposals: 1. the optical superposition reflecting device: by utilizing an optical superposition method, adopting total 64 sheets of reflecting mirrors (five layers with each layer having 8 sheets added with 3 multiplied by 8), the sunlight is fully superposed on a silicon chip on different levels; 2. the equilibrium principle is utilized to cause the point of strength of the whole tracking device to be on the overcoming of the damping of a bracket instead of the self weight of the bracket, therefore, a gear box is not easy to be damaged and has long service life, and power consumption is saved; and 3. a radiator: a metal radiating fin, a fan and an upper end thermal insulation parasol are prepared. The device can beautomatically started to implement temperature reduction when the temperature of the silicon chip reaches 50 DEG C.

Description

technical field [0001] The invention mainly relates to a solar silicon wafer power generation device, in particular to a photovoltaic power generation device with a sunlight tracking device. Background technique [0002] At present, in the photovoltaic power generation industry, there are many ways to improve the power generation efficiency of silicon wafers, but the effective magnification is not large, and there is a problem of high cost when applied to grid-connected power generation. At the same time, the large-scale solar tracking mechanism has the following worldwide technical problems: the gear box is often damaged, the maintenance cost is high, and it cannot generate electricity normally. The reason is that its intermittent tracking technology is flawed. If the angular acceleration is too large when starting, especially when stopping, the gearbox will be damaged in a short time, and eventually it will not work normally. Contents of the invention [0003] The purp...
