Embodiment Construction

[0092] Such as Figure 1-2 , 5, a single main girder multi-point drive solar tracking system, including a main girder 12 and at least one rotary speed reducer 1, the number of the rotary speed reducer 1 can be arranged according to the specific situation, can be 1 or 1 More than one setting, the internal structure of multiple rotary reducers 1 is exactly the same setting; one of the rotary reducers is connected to the motor 3, the motor 3 is controlled by the motor controller, and the controller of the motor 3 is connected to the motor by a cable; The rotary reducer 1 connected to the motor 3 is an active rotary reducer, and the other rotary reducers 1 are driven rotary reducers. The torque of the active rotary reducer is transmitted to the driven rotary reducer through the transmission shaft 10, and the active rotary reducer and The driven rotary reducer rotates synchronously, and then drives the main beam 12 to rotate.

[0093] Such as figure 1 As shown, in some embodiment...

Abstract

The invention discloses a single main girder multi-point drive solar tracking system, comprising a main girder and at least one rotary reducer, wherein one rotary reducer is connected with a motor; the rotary reducer connected with the motor is an active rotary reducer, The other rotary reducers are driven rotary reducers, and the torque of the active rotary reducer is transmitted to the driven rotary reducer through the transmission shaft; the rotary reducer, the transmission shaft and the main beam are set to rotate in the same direction synchronously. In the present invention, the drive shaft and the main beam move in the same direction synchronously, and then the drive shaft can be supported by the main beam, and the drive shaft is not easy to twist or break, and has a long service life, and under this structure, the diameter of the drive shaft does not need to be set If it is too large, the equipment investment cost is low; and because the transmission shaft, motor, and main girder are all rotated synchronously, the photovoltaic panel will not collide with the transmission shaft during the turning process of the main girder, and the adjustable angle of the main girder is larger and more flexible. The degree is higher, and the service life of the equipment is extended.

Description

technical field [0001] The invention belongs to the technical field of solar power generation, and in particular relates to a single main girder multi-point driving solar tracking system. Background technique [0002] The proportion of solar photovoltaic power generation in the electricity market is rising rapidly, and the market prospect is extremely promising. In large-scale commercial power stations, the tracking power generation system is used to increase the power generation capacity of the power station by more than 20% compared with the fixed power generation system. Therefore, there will be more and more commercial power stations using tracking power generation in the future, and the single main girder multi-point drive solar tracking power generation system is also ( Tracking Brackets) make more demands. The horizontal single-axis or inclined single-axis tracking power generation system, which is the current mainstream in the market, has an increasing installed pow...
