Embodiment approach

[0035] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS When the main motor 5 drives the heat collector to rotate around the main shaft 6, read the values ​​of the angle sensors arranged on the central heat collecting tube support and the heat collecting tube supports at both ends, and obtain the deflection angle of the two ends of the axis and the deflection angle of the central axis, According to the angle deviation signal between the deflection angle of the end shaft and the deflection angle of the central shaft, the synchronous motor 10 at the corresponding end is driven to drive the synchronous wheel 11 to rotate, so that the synchronous belt 12 drives the weight 13 to move in the corresponding direction to compensate the torque. The torque compensation process ends when the angle deviation returned by the central angle sensor 4 and the end angle sensor 8 is zero.

[0036] Signal transmission is realized between the angle sensor and the synchronous motor through wires.

Abstract

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.

Description

technical field [0001] The invention relates to the field of solar energy development automation, in particular to an adaptive torque compensation device and a working method for a trough solar heat collector. Background technique [0002] The trough solar thermal power generation system is called the trough parabolic mirror solar thermal power generation system. It arranges multiple trough parabolic concentrating collectors in series and parallel to focus the direct sunlight and heat the working fluid in the vacuum heat collecting tube. High temperature is generated, and then the water is heated by heat exchange equipment to generate high temperature and high pressure steam, which drives the steam turbine generator set to generate electricity. Trough solar thermal power generation is the only type of solar thermal power generation system currently in commercial operation in the world. [0003] When the trough collectors track the sun, the motor located in the middle of a r...
