A hoisting device for a heliostat

Abstract

The invention discloses a heliostat hoisting device. The hoisting device comprises a hoisting frame, overturning frames, push mechanisms, leveling mechanisms, locating and locking anti-rotation mechanisms, position detection sensor modules and leveling sensor modules. The hoisting frame of the hoisting device is composed of a main frame, hoisting lugs, side hanging rings, overturning drivers, overturning supports and overturning lug seats B. The hoisting frame is hinged to all the overturning frames through rotating shafts, the overturning drivers and the like. All the overturning frames can rotate freely within the range from 0 degree to 90 degrees through the overturning drivers and are linked with the push mechanisms through sliding modules and push drivers correspondingly. Each push mechanism can slide in a plane of the corresponding overturning frame. The locating and locking anti-rotation mechanisms and the leveling mechanisms are mounted on the push mechanisms through bottom attachment plates. The position detection sensor modules are mounted on the bottom attachment plates. The leveling sensor modules are arranged on the main frame and used for detecting the left-right height of heliostats and feeding back to the leveling mechanisms to execute relevant actions.

Description

technical field [0001] The invention relates to the field of solar thermal power generation, relates to a tower type solar thermal power generation system, and in particular to a hoisting device for a heliostat. Background technique [0002] While the economy continues to develop, energy is increasingly in short supply, traditional non-renewable energy is increasingly exhausted, and economic development is increasingly constrained by the development and utilization of energy. The utilization of renewable energy has attracted widespread attention, especially the utilization of solar energy has attracted more attention from the world. [0003] Solar thermal power generation is a major way of utilizing solar energy at present. The current solar thermal power generation can be divided into (1) tower solar thermal power generation; (2) trough solar thermal power generation; (3) dish solar thermal power generation according to the way of solar energy collection. [0004] In the f...

[0007] However, at this stage, the single heliostat in the existing actual photothermal projects often reaches more than 20 square meters, and the weight of the single glass also increases accordingly, and the assembly is also very dangerous, which is no longer suitable for manual on-site assembly work; The length of the heliostat spreader is often more than 10 meters, and the weight is heavy. The lifting method of moving the spreader from the side to the fixed position of the heliostat is time-consuming and laborious, and it is easy to damage the heliostat; at the same time, the existing heliostat hoisting device , when hoisting, it is necessary to adjust the position of the spreader so that it can be fixed with the heliostat. Since the heliostat and the spreader are very large, it is very inconvenient to adjust the fixed position, which seriously affects the efficiency of lifting; at the same time, it is necessary to constantly adjust the two In addition, during the hoisting process of the existing heliostat, the connecting seat connecting the heliostat and the installation column will be hoisted together with the heliostat, so as to speed up the overall heliostat installation. installation speed of

However, in the existing hoisting schemes, it is impossible to perform overall leveling of the heliostat during hoisting (that is, keep the mirror surface of the heliostat parallel to the mounting surface of the lifting lug of the lifting frame), so that the horizontal plane of the hoisting frame and the bottom of the connecting seat are installed The surface cannot be kept relatively parallel, which eventually leads to the inability to align the connecting seat and the mounting column surface smoothly, greatly reducing the overall installation efficiency of the heliostat
