Embodiment Construction

[0093] Such as Figure 1-3 As shown, in some embodiments, a tracking transmission system with a multi-point support transmission shaft includes a main beam 19a and at least one rotary speed reducer 1a, the number of the rotary speed reducer 1a can be arranged according to the specific situation, and can be There are one or more settings, and the internal structure of multiple rotary reducers 1a is exactly the same; one of the rotary reducers is connected to the motor 3a, and the motor 3a is controlled by the motor controller. Between the motor controller and the motor 3a connected by cables; the rotary reducer 1a connected to the motor 3a is an active rotary reducer, and the other rotary reducers 1a are driven rotary reducers, and the torque of the active rotary reducer is transmitted to the driven rotary reducer through the transmission shaft 10a, The driving rotary reducer and the driven rotary reducer rotate synchronously, and then drive the main beam 12a to rotate.

Abstract

The invention discloses a tracking drive system with a multi-point support drive shaft. The system comprises a main beam and at least one rotary speed reducer, one rotary speed reducer is connected with a motor and is in transmission connection through a transmission shaft, the transmission shaft is positioned in the main beam, and a universal corner joint is arranged in the rotary speed reducer. The transmission shaft is located in the main beam, the transmission shaft is prevented from being affected by severe environments, the problems of corrosion, aging and the like of the transmission shaft are solved, and the service life of the transmission shaft is prolonged; besides, the situation that the transmission shaft is stuck due to sandstorm is reduced, and the failure rate is reduced; and moreover, the transmission shaft is arranged inside, so that the appearance layout of the whole equipment is simpler and more attractive.

Description

technical field [0001] The invention belongs to the technical field of solar power generation, and in particular relates to a tracking transmission system with multi-point supporting transmission shafts. Background technique [0002] The proportion of solar photovoltaic power generation in the electricity market is rising rapidly, and the market prospect is extremely promising. The use of tracking power generation systems in large-scale commercial power plants increases the power generation of power plants by more than 20% compared with fixed power generation systems, so there will be more and more commercial power plants using tracking power generation in the future. [0003] At present, the existing solar power plants are usually installed in areas where the environment is relatively harsh (such as plains and deserts), and sandstorms, corrosive gases, rain, etc. can all shorten the life of the drive shaft and affect the use of the drive shaft.
