AI Technical Summary

Problems solved by technology

The horizontal single-axis or inclined single-axis tracking power generation system, which is the current mainstream in the market, has an increasing installed power due to the increase in component power, and its structural shortcomings are also becoming more and more obvious. It has gradually failed to adapt to the higher and more use requirements of future trackers.
At present, in the existing tracking transmission system, the main beam cannot be installed or the length is not enough due to the size error of the column due to the foundation construction.

Embodiment Construction

[0056] like figure 1, shown in 11 and 13, in some embodiments, a tracking drive transmission mechanism for multi-point drive flat single shaft, including the main beam 1 and at least one rotary reducer 10, the number of the rotary reducer 10 can be According to the specific situation, one or more can be set, and the internal structure of multiple rotary reducers 10 is exactly the same; one of the rotary reducers 10 is connected to the motor 11, and the motor 11 is controlled by the motor controller. The motor controller and the motor 11 are connected by cables; the rotary reducer 10 connected to the motor 11 is the active rotary reducer 10, and the other rotary reducers 10 are driven rotary reducers 10, and the torque of the active rotary reducer 10 passes through The transmission shaft 12 is transmitted to the driven slewing reducer 10, and the transmission shaft 12 rotates around the main beam 1 while being self-propagating. Then the main beam 1 is driven to rotate.

Abstract

The invention discloses a solar tracker. The solar tracker comprises a main beam and at least one rotary speed reducer, one rotary speed reducer is connected with a motor, the motor is controlled by a motor controller, and the motor controller is connected with the motor through a cable; and the main beam is arranged in the rotary speed reducer in a penetrating manner. The main beams penetrate through the middle of the speed reducer, so that the main beams can be longer, joints between the main beams can be effectively reduced, the rigidity and the strength of the whole-row support are improved, and the risk is reduced.

Description

technical field [0001] The invention belongs to the technical field of solar power generation, and in particular relates to a solar tracker. 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 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 power due to the increase in component power, and its struc...
