Problems solved by technology

The above-mentioned support devices use adhesive to bond the suction cup to the reflector, and then connect the supporting steel member through the suction cup. Due to the aging and failure of the adhesive, it is difficult to guarantee the 30-year service life of the heliostat system
In addition, these types of heliostat support devices adopt the traditional steel truss structure type, which consumes a large amount of steel

Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] The embodiment of the invention is a cable truss type heliostat support device in a tower solar thermal power generation system.

[0029] Overall structure of the present invention is as figure 1 , figure 2 and image 3 shown. The supporting device of the heliostat includes a reflector 1 , a docking system 2 , a steel cable net 3 , a truss 4 , a profiled steel cable 5 , a transverse shaft 6 , a column 7 and a driving device 8 .

[0030] The reflector 1 is composed of a plurality of sub-mirrors, and all the sub-mirrors are arranged together to form a complete plane reflector 1 . Through the connection of the docking system 2 at the corner positions and central point positions of multiple sub-mirrors of the reflector 1, the steel cable net 3 connects each sub-mirror as a whole, and the steel drag cable 5 connects the plane surface of ...

Abstract

A cable truss type heliostat supporting device comprises a reflector (1), connecting systems (2), a steel inhaul cable net (3), trusses (4), type adjusting steel inhaul cables (5), transverse shafts (6), a stand column (7) and a driving device (8). Through connection of the connecting systems (2) at the corner point positions and the center point positions of a plurality of sub-mirrors of the reflector (1), all the sub-mirrors are connected into a whole through the steel inhaul cable net (3). The plane face type of all the sub-mirrors is converted into a double-curvature condensation face type through the type adjusting steel inhaul cables (5). Each truss (4) is connected with the steel inhaul cable net (3) and the corresponding type adjusting steel inhaul cables (5) in a multi-point supporting mode. The two transverse shafts (6) are inserted into holes of the trusses respectively in a penetrating mode and connected with the trusses (4). The driving device (8) is installed at the upper end of the stand column (7) and connected with the two transverse shafts (6). Thus, the trusses (4), the transverse shafts (6), the driving device (8) and the stand column (7) are connected into a whole.

Description

technical field [0001] The invention relates to a supporting device of a solar heliostat system. Background technique [0002] The heliostat (tower concentrator) is an important investment unit of the tower solar thermal power station, accounting for about 50% of the initial total investment. Therefore, the cost reduction of the heliostat can greatly reduce the initial total investment and power generation of the power station. Cost, realize the low power generation cost of the tower power station. Heliostats include reflectors, drive systems, control systems and support devices. A reasonable support device can reduce the amount of steel used, improve the surface accuracy of the reflector, facilitate the processing, assembly and debugging of the heliostat, and help reduce the cost of the heliostat. For this reason, heliostat designers have also developed various heliostat supporting devices. US Patent No. 4,456,332 discloses a heliostat supporting device, and Chinese paten...
