Curvature-variable double parabolic plate rear support moment parallel structure

Abstract

The invention discloses a curvature-variable double parabolic plate rear support moment parallel structure. The structure comprises a base frame, a balance beam, a mirror unit, a jacking rod, a pull rod and a limiting rotating shaft, wherein the mirror unit is mounted on the balance beam through the limiting rotating shaft; the upper part of the mirror unit is connected with the balance beam through the jacking rod; the lower part of the mirror unit is connected with the balance beam through the pull rod; the balance beam is fixedly mounted on the base frame; the connection point of the balance beam and the base frame is the fulcrum of the base frame; the integral structure formed by the balance beam, the mirror unit, the jacking rod, the pull rod and the limiting rotating shaft has a zero resultant moment on the fulcrum of the base frame. According to the invention, a relevant support device is arranged according to the moment equilibrium principle to drive two parabolic solar reflectors; meanwhile, a limiting rotating shaft structure is arranged to connect the two parabolic reflectors, reliability and stability in mirror motion tracking are achieved through the support device during the operation of the device, adaptability to parabolic mirrors of different curvatures and different opening sizes is achieved through the limiting rotating shaft structure, and the support device is not only simplified but also enabled to operate effectively and reliably.

Description

technical field

[0001] The invention relates to a support structure, in particular to a rear support structure of a solar luminescent thermal mirror with on-line installation and debugging synchronization. Background technique

[0002] In the usual solar thermal power generation equipment, the reflector accounts for a large proportion and the manufacturing cost accounts for more than half of the total. The weight of the support structure of the reflector is 60-70% of the total weight. Therefore, the driving of the mirror and its tracking system are often equipped with high-power motor equipment, and correspondingly, they also encounter problems caused by high-power devices, such as operation stability, reliability, and power consumption costs. Specifically, the general mirror device is driven by torque, and the torque is determined by the total torque. Therefore, once the torque problem is solved, it is converted into how to adjust the rotational torque of the entire system ...
