Description
Technical field
The utility model relates to a kind of solar power generation unit, relates in particular to a kind of combination concentration and power generation unit of concave reflecting mirror.
Background technology
Concentrating solar photovoltaic generating can reduce the photovoltaic generation cost significantly.Along with improving constantly of new and effective concentrator cell efficient, concentrating generating system will be more and more important in the solar energy power generating field.Light-gathering optics has various ways, and main application is parabolic reflector formula point focusing system at present, and the advantage of this system is: can change more high efficiency battery; Light concentrating times is variable; Cost low (the speculum cost is low, and light concentrating times can be very high, to the demand minimizing of battery).But following shortcoming is arranged also: the one, reflector element is made complicated, the reflector element different parts need be made different moulds, and required precision is higher, local error, to cause the inhomogeneous of battery surface Energy distribution, form focusing and cause receiver to damage on the receiver surface easily, perhaps the excessive receiver that overflows of hot spot reduces generating efficiency and reduce energy output; The 2nd, to the anti-thick property requirement height of speculum, to stand outdoor long operation.And the reflecting mirror material that is suitable for work under the outdoor conditions at present involves great expense, and is not suitable for large-scale production to requirement cheaply.
The utility model content
The purpose of this utility model is to solve the problems referred to above that prior art exists, provide a kind of cost low, be easy to process, the anti-thick property of reflector element is good, be easy to assemble, tracking accuracy is required not high again combination concentration and power generation unit of concave reflecting mirror.
The purpose of this utility model is achieved in that a kind of combination concentration and power generation unit of concave reflecting mirror, comprise concentrator and sunlight receiver, described concentrator is made up of at least one concave mirror array, described concave reflection lens array comprises support frame and a plurality of concave mirror, a plurality of concave mirrors are compactly arranged of installation on support frame with different inclination angles, the shape the when position of each concave mirror guarantees that its sunlight with incident converges to the sunlight receiver outer surface and the shape and the position basically identical of position and sunlight receiver outer surface.
Described concave reflection lens array also comprises transparent cover plate, and transparent cover plate covers on a plurality of concave mirrors and with support frame and is fixedly linked.
Described a plurality of concave mirror is rectangular block of the same size, and the radius of curvature equal and opposite in direction of each concave mirror.
Described a plurality of concave mirror is rectangular block of the same size, and the radius of curvature of each concave mirror varies in size.
Described concentrator is made up of a plurality of concave mirror arrays, and a plurality of concave reflection lens arrays are the center symmetric arrays with the receiver central shaft.
The equal and opposite in direction of described a plurality of concave reflection lens arrays.
Varying in size of described a plurality of concave reflection lens arrays.
Combination concentration and power generation unit of concave reflecting mirror of the present utility model, concave mirror on its concentrator can have identical radius of curvature and close overall dimension, in the production process of concave reflection lens array, just only need a kind of mould like this, help reducing cost, meet needs of scale production; Simultaneously the concave reflection lens array by support frame, be installed in a plurality of concave mirrors on the support frame and the transparent cover plate that covers on a plurality of concave mirrors is formed, so just concave mirror in the unit and external environment are kept apart, make it avoid the influence of most of extraneous unfavorable factor, improved the anti-thick ability of whole concave reflection lens array, reduced weatherability requirement to reflecting mirror material, thereby can use more cheap reflecting mirror material, also reach the purpose that reduces cost.And this structure concentrator is simple to operate, is easy to install.
