Self-adaptive torque compensation device and working method of trough-type solar collector

The invention discloses a self-adaptive torque compensation device and a working method of a trough-type solar collector in the field of automation of solar energy development. The self-adaptive torque compensation device of the trough-type solar collector comprises heavy objects, a transmission mechanism and angle sensors, wherein the transmission mechanism is connected with a bracket on an outermost keel of a collector array; and the heavy objects can change position under the driving of the transmission mechanism. The working method comprises that the positions of the heavy objects are controlled by deflection signals transmitted by the angle sensors, and then the purpose of torque compensation is reached. By the self-adaptive torque compensation device and the working method, tracking precision of the trough-type solar collector is guaranteed, and the collector is ensured to work stably and efficiently. By the self-adaptive torque compensation device, torque loss of the trough-type solar collector during the rotation process, due to various reasons, can be regulated in time, the tracking precision of the trough-type solar collector is increased, and heat-collecting efficiency of the collector is improved.
