Problems solved by technology

This tracking driving method has low tracking accuracy (about 1.7mrad), which cannot meet the high tracking accuracy requirement of 1.2mrad required by high-temperature molten salt working fluid.
And the motor starts and stops frequently, and the reversing valve moves frequently, which seriously affects the life of the unit
When driven by a single-pump fixed-speed motor, the speed of movement cannot be adjusted when implementing fast positioning

Abstract

The invention discloses an anti-freezing hydraulic cylinder structure with an ice scraping device. The hydraulic cylinder structure is characterized by comprising a first oil cylinder, a second oil cylinder, a balance valve set, a hydraulic rubber tube, a hydraulic oil tank, a motor, a pump outlet oil path distribution valve set, an energy accumulator, an energy accumulator outlet valve set and the ice scraping device. The system can drive a heat collector to rotate and track the sun angle in real time, the required tracking precision is guaranteed, the system has an emergency fast positioningfunction and a defocusing protection function in emergency situations, and can adapt to rainy and snowy weather, and the influence of ice slag on the oil cylinder can be eliminated.

Description

technical field [0001] The invention belongs to the technical field of solar thermal power generation, and in particular relates to an antifreeze hydraulic cylinder structure with an ice scraper. Background technique [0002] At present, solar thermal power generation technology has entered a period of rapid development. Solar parabolic trough power generation is a technology that uses a linear parabolic reflector that tracks the movement of the sun to gather solar radiation into a heat-absorbing tube located at the focal line of the parabola to heat the heat transfer fluid for power generation. The key equipment of the trough power station mainly includes heat collectors, heat absorbing pipes and heat storage. The drive tracking system is the core of the solar collector, and it is the guarantee for the photothermal collector to make full use of solar energy. With a drive tracking system, the solar thermal harvester can track the sun from sunrise to sunset. The tracking d...
