Problems solved by technology

Most of the existing solar medium and high temperature heat collection technologies use trough (composite curved surface) reflective heat collectors. Traditional trough heat collectors use one-time focusing, which has low efficiency, especially in winter or when the sunshine condition is bad, and cannot meet the demand well. , and most of the receiving devices are installed at a high position, resulting in a larger windward side and greater heat loss

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0023] Such as figure 1 As shown, the three-time focusing solar energy receiving device disclosed in the present invention includes a focusing mirror 1, a trough reflecting surface 2, a focusing device 3 and a receiver 4;

[0024] The focusing mirror 1 and the grooved reflecting surface 2 are used to reflect sunlight to the focusing device 3 for three times of focusing;

[0025] The receiver 4 is installed in a low position, and is installed under the trough reflective surface 2;

[0026] The grooved reflecting surface 2 is installed above the focusing device 3 through a support frame and arranged in a north-south direction; the focusing mirror 1 and the focusing device 3 are fixed on the ground through a base frame.

[0027] The trough reflective surface 2 may be a parabolic reflective surface, an ellipsoidal reflective surface, a hyperboloid of revolution, or other...

Abstract

The invention discloses a thrice focusing solar energy receiving device which belongs to the technical field of solar devices. The thrice focusing solar energy receiving device provided by the invention comprises a focusing mirror, a slot type reflecting surface, a focusing device and a receiver, wherein the focusing mirror and the slot type reflecting surface are used for reflecting sunlight into the focusing device for thrice focusing; the receiver adopts a low position mounting way and is mounted below the slot type reflecting surface; the slot type reflecting surface is mounted above the focusing device through a support and distributed lengthways; the focusing mirror 1 and the focusing device are fixed on the ground through a bedframe. According to the invention, trice focusing solar energy is adopted, focusing heat or photoelectricity collection can be achieved, and the relieving rate of the system is improved. The thrice focusing solar energy receiving device provided by the invention adopts the low position mounting way, heat dissipation and wind resistance are reduced, and the stability of the system is enhanced, and the cost is lowered.

Description

Technical field [0001] The invention relates to a three-time focusing solar energy receiving device technology, which belongs to the technical field of solar energy devices. Background technique [0002] Solar energy is a clean and abundant renewable energy. Solar energy is the most abundant and widely available form of renewable energy in my country and the world. Solar thermal utilization is mainly divided into low-temperature heat utilization, medium-temperature heat utilization and high-temperature heat utilization. Most of the existing solar medium and high temperature heat collection technologies use trough-type (composite curved surface) reflective heat collection devices. Traditional trough-type heat collection devices use one-time focusing, which is low in efficiency, especially in winter or when the sun is poor, which cannot meet the demand well. , And most of the receiving devices are installed in a high position, resulting in a larger windward surface and a larger he...
