Problems solved by technology

U.S. Patent No. 4,488,779 discloses a new structure of heliostats. It uses steel wire ropes to replace the steel used in traditional structures to reduce the weight of the heliostats. The disadvantage of this structure is that the steel wire ropes must be in tension. It cannot work normally, it is difficult to guarantee the reliability and stability of the system, and it is impossible to guarantee high tracking accuracy, which will reduce the power generation efficiency
[0003] Tower-type solar power plants generally require hundreds or even thousands of sets of heliostats, and each set of heliostats may be divided into several reflector units, so the workload of manufacturing and installing heliostats is very large, and workers When installing heliostats, it is necessary to work at heights, which makes the installation work more difficult

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] The embodiment of the invention is a 100m tower solar power generation system 2 Rectangular heliostats.

[0022] Overall structure of the present invention is shown in Figure 1. The supporting device for the heliostat is composed of a column 11 , a transverse shaft 13 , a supporting arm assembly 12 and a mirror supporting frame assembly 14 . The components that make up the support arm assembly 12 and the reflector support frame assembly 14 are made of non-metal profiles, such as plastic steel profiles, which can reduce the weight of the heliostat support structure and reduce the system cost. The cavity of the non-metal profile is stiffened, and the section shape of the profile can be grid-like, triangular or other shapes, so that the profile has a certain wind pressure resistance. The center lines of the column 11 and the horizontal a...

Abstract

The invention relates to a heliostat support structure, formed by a post (11), a transverse axle (13), a support arm (12) and a mirror support frame (14), wherein the support arm (12) and the mirror support frame (14) have all elements made from non metal section bar, to reduce weight and the load of transmitter, thereby using small power motor to reduce system cost. The chamber of the non-metal section bar is arranged with rib plates inside, to obtain wind resistant ability. The support arm (12) and the mirror support frame (14) are connected via a porous connector, to support easy installment and adjust the installed height of the mirror support frame (14). The invention can mount a roller element (61) on the mirror support frame (14) to reduce installment time and cost.

Description

technical field [0001] The invention relates to a supporting device of a solar heliostat device. Background technique [0002] A heliostat is a device that reflects sunlight and focuses it on a fixed target. It includes reflectors, supporting structures, transmission systems, and tracking control systems. Heliostats are usually used in tower-type solar power generation systems, and the cost of heliostats accounts for about 50% of the total system cost. Therefore, in order to reduce system power generation costs and accelerate the commercialization process of tower-type solar power generation systems, the fixed Sun mirror cost. Among them, if the weight of the supporting structure of the heliostat is reduced, the load of the transmission system can be greatly reduced, the structural size of the transmission system can be reduced, and the power required by the motor can be reduced, thereby reducing the self-consumption of the system and reducing the system cost . In order t...
