Problems solved by technology

[0006] First, because the spot size increases with the distance between the spot collection device and the heliostat, for a mirror field with tens of thousands of heliostats, the distance between the spot collection device and the heliostat is usually far , the size of the light spot falling on the imaging plate is larger, so the area of ​​the imaging plate is often larger, and the resulting wind resistance is also large
Strong wind resistance is very unfavorable to the collection of light spots. The light spot imaging device will shake to varying degrees under the action of the wind, which will not only affect the quality of light spot collection, but may even cause damage to the imaging device.
In order to make the imaging plate strong enough to withstand strong wind resistance, it needs to spend high production and installation costs.
[0007] Second, since the planar imaging plate is integrated, when the imaging plate needs to be maintained or replaced, the entire imaging plate must be operated, which is costly, troublesome to operate, and long in cycle

Embodiment 1

[0042] see Figure 1 to Figure 3 , The tower solar spot collection system generally includes a gap-type spot imaging device 1, a spot collection device 2, a heliostat 3, and a computer control subsystem 4. The computer control subsystem 4 controls the designated heliostat 3 to track the sun, and reflects the sun's rays to the spot imaging device 1 located on the receiving tower; System 4 processing to study the characteristics of the spot.

[0043] Wherein, the above-mentioned gap-type spot imaging device 1 includes a support mechanism 11 and a spot imaging part 12 with a gap thereon, and the spot imaging part 12 includes at least two imaging units 121, and the planes where the imaging units 121 are located are parallel to each other, and through the support mechanism 11 is connected and fixed; there is a gap between adjacent imaging units 121 . The imaging unit 121 can be installed along a horizontal direction, a vertical direction or a direction forming a certain angle wit...

Embodiment 2

[0051] Such as Image 6 As shown, a gap-type spot imaging device 1 includes a support mechanism 11, a spot imaging part 12 with a gap thereon, and an angle adjustment mechanism 13 for adjusting the angle of the imaging unit, wherein the spot imaging part 12 is composed of several imaging units 121 , the planes where all the imaging units 121 are located are parallel to each other, and there are gaps between the adjacent imaging units, which are connected and fixed by the supporting mechanism 11 .

[0052] In this embodiment, the supporting mechanism 11 includes a frame 111, on which a frame shaft 112 corresponding to each imaging unit 121 is provided, and each imaging unit is fixed on the frame through its corresponding frame shaft. All the axes 112 are on the same plane, and the imaging unit 121 can be flipped around the axes 112 .

[0053] The angle adjustment mechanism 13 is connected with the imaging unit 121, and the angle adjustment mechanism 13 can adjust the angle of ...

Embodiment 3

[0062] Such as Figure 9 As shown, a gap-type spot imaging device 1 includes a support mechanism 11 and a spot imaging part 12 with a gap thereon, wherein the spot imaging part includes at least one imaging unit, and the imaging unit is fixed on the support mechanism 11 .

[0063] In this embodiment, the spot imaging part includes an imaging unit 121 , which has a porous surface structure, and a number of hole-shaped gaps are distributed on its surface, through which airflow can pass. In this embodiment, the holes 125 are round holes, but not limited thereto, and the hole type, quantity, spacing, and distribution method can be determined according to the actual situation.

Abstract

The invention discloses a gap type facula imaging device, which comprises a support mechanism and a facula imaging portion provided with a gap. The facula imaging portion at least comprises an imaging unit fixed on the support mechanism. In a better embodiment of the gap type facula imaging device, the facula imaging portion comprises at least two imaging units, planes of the imaging units are mutually parallel, and the imaging units are connected to be fixed through the support mechanism. Gaps are retained between adjacent imaging units. The imaging units can be installed along the horizontal direction, the vertical direction or the direction having a certain included angle with the support mechanism. Compared with the prior art, the gap type facula imaging device resolves the problem of air resistance of an integral type facula imaging device, and simultaneously reduces manufacture, installation and maintenance cost.

Description

technical field [0001] The invention relates to the technical field of solar energy collection and utilization, in particular to a gap-type spot imaging device. [0002] Background technique [0003] With the development of economy and industry, the demand for energy is increasing, especially electric energy is an indispensable energy in industry and people's life. Traditional power generation methods, for example, coal power generation is too dependent on coal mines, and coal is a non-renewable resource with high pollution. Traditional power generation modes such as coal power generation can no longer meet the needs of industrial and economic development. For this reason, people pay more and more attention to clean and renewable energy. Among many clean energy sources, solar energy plays a more important role because of its wide coverage, that is, it can be used wherever there is sunshine, and is therefore widely used in in the field of power generation. In the solar en...
