Problems solved by technology

[0003] Among the above two methods, the tower type has a limited area for collecting light energy, and the installation and maintenance of related equipment on the top of the tower is also more troublesome; for the trough type, due to the long-distance heat transmission, there are problems such as sealing and heat loss, and maintenance is also troublesome.
The heat collection and transmission loss of the trough type is not small, and it does not support long-distance heat transmission

Embodiment 1

[0030] Such as figure 1 As shown, the present embodiment is a light transmission relay unit of a single structure, which includes three parts such as a light collection device 1, a connection adjustment structure 3 and a far-point reflection and convergence device 2; Light is first incident from the light collecting device 1 , that is, the wide mouth of the tapered funnel structure, and the arrow 8 is its incident direction. After multiple reflections and convergence on the internal reflection surface 4 of the funnel, it finally shoots out from the narrow mouth of the conical funnel structure, that is, the first focal point 5 in the vicinity, and then reflects on the reflection concave surface 6 of the far-point reflection and convergence device 2, and then converges on the far point. Second focus 7 position.

Embodiment 2

[0033] Such as figure 2 As shown, it is the combined application of the device of the present invention figure 1 The model of the combination of three light transmission relay units and two solar reflector arrays shown: first, the first light transmission relay unit 13 receives the collected light from the first solar reflector array 11, collects, reflects and converges to The collection device of the second light transmission relay unit 14; at the same time, the collected light 17 of the second solar reflection mirror array 12 also converges to this collection device. After the two beams converge, they are collected, reflected and converged in the third light transmission relay unit 15 , and then collected and reflected, and then converged in the heat collector 16 .

[0034] In this embodiment, the three light transmission relay units are arranged in series, and a second sunlight reflector array 12 is added in the middle of the light path structure.

Embodiment 3

[0036] Such as image 3 As shown, in the present embodiment, the light collection device is used to carry out the use model of the cluster structure. First, the reflected light beams of the A solar reflector array 21 and the B solar reflector array 22 are converged to the fourth light transmission relay unit 25. B. The light collecting device 23, here the structure is a cluster shape, can simultaneously receive the reflected light beams of a plurality of sunlight reflector arrays. The collected light is collected, reflected, and converged to the fifth light transmission relay unit 27 , and then collected and reflected, and then converged to the heat collector 29 .

[0037] In this embodiment, the two light collection devices are bundled to receive the reflected light beams of the two solar reflector arrays. In actual use, multiple light collection devices can be bundled according to actual needs to correspond to A plurality of solar reflector arrays improves its use efficienc...

Abstract

The invention discloses a light gathering power transmission one body type integration relay system. The system comprises several light transmission relay units which are arranged in series and / or in parallel and several sunlight mirror arrays. The previous level light transmission relay unit successively transmits the gathered light to the next level light transmission relay unit so as to prolong a transmission distance. The light transmission relay units comprise light collection devices which are used to collect the light reflected by the sunlight mirror arrays and far point reflection gathering apparatuses which are used to carry out reflection and gathering to the gathered light, wherein one far point reflection gathering apparatus corresponds with one light collection device or several light collection devices which are parallely arranged. The system of the invention is formed by combining one or more light gathering power transmission one body type integration relay apparatuses. A light path system is established between a plurality of the sunlight mirror arrays and photothermal conversion heat collection devices. Restrictions of space and geographical obstacles can be overcome, apparatuses can be simplified and costs can be reduced.

Description

technical field [0001] The invention relates to an integrated relay system for light concentrated energy transmission. Background technique [0002] In the current photothermal power generation industry, there are mainly two types of concentrating devices: trough type and tower type. The tower type uses the controlled reflection of the mirror array light reflection unit to directly gather the sunlight to the tower type light collector. Generally, a single tower structure is adopted to collect the reflected light in a limited area around it, and then heat absorption, heat exchange, and heat conduction are used to transfer the sunlight to the tower type light collector. The collected heat is sent to the thermal power generation system. In addition, the trough power generation is generally single-axis tracking, and the focal point trajectory of the reflected sunlight is a straight line. A light-heat collector tube is placed on the straight line. The tube is about tens of meter...
