Technical field

The invention relates to a solar power plant.

Background technique

The existing solar power generation equipment is divided into two types: fixed type and reversible type. The reversible solar power generation equipment is further divided into a single-axis turning type solar power generation device which can swing around only one axis, and can be flipped around two different rotating shafts. Chasing photovoltaic power generation equipment.

For example, a prior art photovoltaic power generation device includes: an erected support and a cross-turning mechanism, and a cross-turning mechanism is disposed at an upper end of the support. The cross-turning mechanism has a fixed base and a cross-shaped connecting member. A straight rod on the cross-shaped connecting member is called a main shaft, and another straight rod perpendicular to the main shaft is called an auxiliary shaft. The base is provided with a pair of lugs, and the pair of lugs are suspended to hang the main shaft of the cross-shaped connecting member. A bearing housing is disposed at each end of the auxiliary shaft on the cross-shaped connecting member, and the two bearing housings are respectively fixed on both sides of a center point of the rectangular tray carrying the array of solar power generating devices. Through the cross-turn mechanism, the tray can swing eastward or westward relative to the upper end of the support (corresponding to the movement of the sun from east to west in each day), and can also perform pitching motion on the upper end of the support (corresponding to the sun exposure in one year) The change in the tilt angle). These two axial movements are respectively driven by the main swing mechanism and the pitch swing mechanism. Usually, the main oscillating mechanism is equipped with a main motor and a main gear reducer. The main gear reducer lowers the rotational speed of the main motor and drives a small main gear to drive a large main gear (usually a sector gear) mounted on the main shaft of the reversing mechanism. The main shaft of the cross-turning mechanism is swung upward or westward with the upper end of the tray relative to the support. The pitch swing mechanism is equipped with an auxiliary motor and an auxiliary gear reducer. The auxiliary gear reducer reduces the rotation speed of the auxiliary motor and drives a small auxiliary gear to drive the large auxiliary gear (usually also the sector gear) mounted on the pallet, so that the two bearing seats of the auxiliary shaft of the cross-turn mechanism are opposite to the tray. The upper end of the support is pitched. The motor of the main oscillating mechanism and the motor of the pitch oscillating mechanism are operated under the control of an intelligent controller, which stores the relationship between the angle between the sun ray and the ground plane at different local times, and makes the tray according to the change relationship. It is always perpendicular to the sun's rays, enabling photovoltaic power generation.

However, in order to achieve high output power, the area of the tray must be large to carry as many solar power generation devices as possible. For example, the current output power is 20,000 watts of solar power equipment, and the rectangular tray has an area of 12 × 12 square meters. Usually, the photovoltaic power generation equipment in Japan is arranged and used in an array.
