Embodiment Construction

[0019] The present invention will be further elaborated below in conjunction with the accompanying drawings and embodiments.

[0020] Such as figure 1 As shown, the detection device based on the reflector of the butterfly solar thermal system, the detection device detects whether the position of the reflector on the solar thermal system is correct, and the reflector is adjusted and installed through the detection of the detection device.

[0021] The solar thermal system includes a reflector steel frame 1, a concentrator fixed on the reflector steel frame and a light receiver 3 fixed on the reflector steel frame and located above the concentrator. The concentrator consists of several The reflecting mirrors 2 are spliced ​​together, and the assembled light collector has a concave reflecting surface.

[0022] The detection device is located between the condenser and the light receiver, and includes a shaft 4, a shaft sleeve 5, a cross bar 6 and a beam meter 7. The shaft is fixe...

Abstract

The invention discloses a detection device and detection method based on a reflector of a butterfly solar photothermal system. By setting a beam meter on the reflective surface of the concentrator that can be easily moved to the coordinates of any reflector on the concentrator, The beam meter emits a vertically downward visible beam. When the vertically downward visible beam irradiates the reflector, adjust the angle of the reflector so that the visible beam is reflected and the spot falls on the focus position set by the light receiver. At this time, the reflector The position is the calibration position, and the reflector is fastened to achieve the purpose of installing and adjusting the position of the reflector. The detection device of the present invention has simple structure, low cost, easy installation, simple detection method and high detection efficiency. The system has difficult problems in the installation, adjustment and re-inspection of each mirror with optical curved surface.

Description

technical field [0001] The invention relates to the technical field of solar thermal power generation, and in particular to a detection device and a detection method for installing and adjusting each single reflector of a large-scale butterfly solar thermal system with optical spherical or parabolic reflectors. Background technique [0002] Solar thermal utilization is very important in the world today, and solar thermal utilization has been listed as a key development project in China's 13th Five-Year Plan. We have made in-depth research on one of the dish solar thermal system engineering. Its principle is to use a high-reflectivity mirror with an optical surface to reflect sunlight and converge it to the theoretical focus to generate high-temperature utilization. In order to obtain more heat energy, the reflective area is getting larger and larger, and the number of small reflectors used is increased. The supporting steel structure system is huge, weighing dozens or even ...
