Embodiment

[0029] Example: such as Figure 1 to Figure 12 As shown, a large-scale heliostat device includes a column 1, a horizontal rotation drive device, and a reflector 3. The column 1 is a hollow structure. A hydraulic station and a storage battery are arranged inside the column 1 . A control box 2 is installed on the side of the column 1 .

[0030] The horizontal rotation driving device includes a base 4 and an upper base 5 . The base 4 is fixed on the upper end of the column 1 . The upper base 5 is rotatably connected to the base 4 . The upper end of the base 4 is fixed with a supporting inner ring 25 . The supporting inner ring 25 is bolted on the base 4 . The supporting outer ring 15 is arranged outside the supporting inner ring 25 . Both the supporting inner ring 25 and the supporting outer ring 15 are annular. An annular first ball groove is provided on the side of the supporting inner ring 25 facing the supporting outer ring 15 , and a second ball groove corresponding ...

Abstract

The invention discloses a large-size heliostat device, and the device comprises a vertical column, a horizontal rotation driving device and a reflection plate, wherein the horizontal rotation drivingdevice comprises a base fixedly connected to the vertical column and an upper base rotationally connected to the base. An eccentric shaft is arranged on the base, and the eccentric shaft deviates fromthe rotation axis of the upper base; at least three hydraulic cylinders are arranged in the circumferential direction of the upper base, and the hydraulic cylinders are rotationally connected with the upper base; the front ends of piston rods of the hydraulic cylinders are rotationally connected with the eccentric shaft; and the reflection plate is rotationally connected to the upper base. The hydraulic cylinders are used as power elements, so the device, compared with a motor, can output a larger torque, and can drive the large reflecting plate to rotate. The main driving device is the hydraulic cylinders, so the hydraulic cylinders, compared with a motor and a speed reducer, are low in cost and simple in structure, and the overall manufacturing cost of a heliostat is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to a large heliostat device. Background technique [0002] In the solar thermal power generation system, the heliostat is an important part of the whole power station. Due to the large area of ​​the mirror field, the position of the heliostat to the central heat collecting tower of the mirror field is far away. The function of the heliostat is to track the position of the sun and reflect sunlight to the heat absorber of the central heat collecting tower of the mirror field, so that solar power can be generated The system can receive enough light energy to improve power generation efficiency. A heliostat usually includes a bracket, a reflector, a horizontal rotation drive device, and a pitch drive device. The horizontal rotation device is used to drive the reflector to perform a horizontal rotation movement, and the pitch drive device is used to drive the reflector to...
