Embodiment Construction

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

[0021] The concentrator of the present invention mainly includes a heat-absorbing tube 1, a transmission tube inner bearing 3, a transmission tube 4, a transmission tube outer bearing 5, a bearing seat 6, a reflector 8, a truss 18, a reflector bracket 7, a support rod 12, and a main drive wheel 9, secondary transmission wheel 19, transmission rod 10, column 13. The driving device includes: 11 steel wire rope, 14 reducer output shaft, 15 reducer, 16 electric motor, 17 tensioner.

[0022] Fig. 1 shows the front view of the trough parabolic solar concentrator of the present invention. As shown in Figure 1, the driving device is arranged between the two concentrators.

[0023] The three heat-absorbing pipes 1 are connected end to end, and each joint position needs to be supported and fixed. The two ends of the concentrator are supported by two c...

Abstract

The invention discloses a trough-type paraboloid solar concentrator which is characterized in that: a heat absorbing tube (1) passes through a transmission tube (4); a bearing (3) in the transmission tube is connected with the heat absorbing tube (1) and the transmission tube (4); when the transmission tube (4) is rotated, the heat absorbing tube (1) is fixed; a paraboloid reflector is rotated around a geometric center of the heat absorbing tube and follows the direct solar radiation; the heat absorbing tube (1) is sheathed in the an inner ring of the bearing (3) in the transmission tube and an outer ring of the bearing (3) in the transmission tube is connected with the transmission tube (4); the bearing base (6) and the transmission tube (4) are connected with each other by an outer bearing (5) of the transmission tube; the transmission tube (4) is sheathed in an inner ring of the of the outer bearing (5) of the transmission tube; an outer ring of the outer bearing (5) of the transmission tube is connected with the bearing base (6) which is fixed a column (13); the column (13) supports the concentrators at both sides by the transmission tube (4). With low maintenance cost and excellent safety performance, the trough-type paraboloid solar concentrator is suitable for the long-term delivery of high temperature and high pressure working substances.

Description

technical field [0001] The invention relates to a trough-type parabolic solar concentrator. Background technique [0002] Solar energy is an inexhaustible renewable energy source. Today, as fossil fuels are decreasing year by year and the international energy situation is becoming increasingly severe, the development and utilization of solar energy is one of the important ways to realize the diversification of energy supply and ensure energy security. The trough-type parabolic solar concentrator uses a parabolic surface to gather parallel solar light, thereby heating the working fluid and generating steam to drive the turbogenerator to generate electricity. Solar radiation consists of direct and diffuse radiation. The proportion of direct sunlight depends on weather conditions (ie cloudy reduces direct solar radiation). Since reflective and refractive concentrators only absorb direct sunlight, the concentrators that work in these two methods must be dynamic, that is, use a...
