Flat single-shaft multi-point driving mechanism capable of passing through main beam torque pipe

Abstract

The invention discloses a flat single-shaft multi-point driving mechanism capable of passing through a main beam torque pipe. The flat single-shaft multi-point driving mechanism comprises a stand column, a rotary speed reducer which is arranged on the stand column and is driven by a motor, a main beam which penetrates through the rotary speed reducer; the rotary speed reducer at least comprises a mounting seat detachably arranged on the stand column, a fixing sleeve arranged on the mounting seat, a transmission box rotationally arranged on the fixing sleeve and a power assembly used for driving the transmission box to rotate relative to the fixing sleeve, a mounting hole for the main beam to penetrate through is formed in the transmission box; and the main beam is connected with the transmission box through a plurality of locking pieces. The main beam penetrates through the middle of the rotary speed reducer and is connected with the transmission box through the locking pieces, so that joints of a group of flat single-shaft main beams can be reduced, the single main beam is longest, material blanking waste is reduced, site construction difficulty is reduced, and installation progress is improved.

Description

technical field [0001] The invention belongs to the technical field of solar power generation, and in particular relates to a flat single-axis multi-point drive mechanism through which a main girder torque tube penetrates inside. Background technique [0002] At present, 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 plants, the tracking power generation system is used to increase the power generation of the power plant by more than 20% compared with the fixed power generation system. Therefore, there will be more and more commercial power plants using tracking power generation in the future. The current market mainstream horizontal single-axis or inclined single-axis tracking power generation Due to the increase of component power, the installed power of the system is increasing, and the shortcomings of its structure are becoming more and more ...

Problems solved by technology

In large-scale commercial power plants, the tracking power generation system is used to increase the power generation of the power plant by more than 20% compared with the fixed power generation system. Therefore, there will be more and more commercial power plants using tracking power generation in the future. The current mainstream horizontal single-axis or inclined single-axis tracking power generation in the market Due to the increase of component power, the installed power of the system is increasing, and the shortcomings of its structure are becoming more and more obvious. It has gradually failed to adapt to the higher and more use requirements of future trackers.

The conventional flat uniaxial main beam is connected to the rotary reducer through joints, and the main beam needs to be cut when unloading, which is easy to cause waste of materials, and will also lead to waste due to the inappropriate length of the main beam caused by the construction error of the on-site column. On-site construction Difficulty is high, affecting the installation progress
