Description

Solar energy heat collector

Technical field

The utility model relates to a kind of heat collector that gathers solar energy, a kind of specifically heat collector that adopts concave mirror and lens to converge solar energy.

Background technology

The tradition solar cooker can only use separately, and contact to each other is little, and when reality was used, its concave mirror can not be made too much again, and daylighting area is limited, and the solar energy that converges is restricted, thereby can't use on a large scale.

The existing solar energy equipment that adopts the flat mirror reflects principle, flat mirror reflects is limited by the restriction of angle of reflection and specular scattering, and its heat collector can not unconfinedly increase, increase again, so the daylighting radius is very limited.

In addition, existing solar cell utilizes conversion of solar energy to be electric energy, and design principle has two kinds, and the one, light-power mode, the 2nd, light-heat-power mode.Light-power mode is produced solar cell cost height, energy conversion efficiency is low, deficiency in economic performance, and this has just limited its large-scale production and large-scale the application; Light-heat-power mode need be collected in abundant light and could obtain enough heats together and generate electricity, this just must be equipped with huge daylighting source, yet the world adopts the flat mirror reflects principle to converge sunshine at present, and this is difficult to reach designing requirement.

Summary of the invention

The utility model is intended to propose a kind of can the use separately at the existing the problems referred to above of existing solar energy heat collection equipment, use also capable of being combined, and the new-type solar energy heat collector that not influenced by sunshine angle of reflection and specular scattering.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is as follows:

A kind of solar energy heat collector, it is characterized in that: comprise first concave mirror that converges sunshine, with one receive the light that above-mentioned concave mirror converges, and second convex lens or second concave mirror launched in the mode of parallel lines, the directional light that described second convex lens or second concave mirror are launched converges on the heat collector through reflector; Described first concave mirror and second convex lens, second concave mirror have same focus.

Described first concave mirror is installed on the travel(l)ing rest.

Described reflector is level crossing or optical fiber.

Be installed on the movable supporting on the described level crossing.

The parallel rays that described second convex lens or second concave mirror are launched is transferred in the optical fiber through the 3rd convex lens.

Advantage of the present utility model is:

One, adopt concave mirror to converge sunshine, by flat mirror reflects to heat collector; Since concave mirror towards can with sunshine inject angle adjustment, level crossing also can correspondingly be adjusted, and makes reflection ray point to heat collector all the time, so just can use up to increase the daylighting radius greatly;

Two, optical fiber just adopts and makes light scattering phenomenon can not take place in communication process, solves the transmission of level crossing light effectively and goes up the lost problem of the energy that exists, and be not subjected to the daylighting radius limit;

Three, use the utility model and make solar cell, the existing light of solution-power mode production cost height, the problem that energy conversion efficiency is low, apply it to light-heat-power mode simultaneously, for it provides the enough energy, overcome and adopted the restriction of flat mirror reflects principle on equipment scale, make the daylighting source is set on a large scale becomes possibility, and cost is not high yet, has good economic benefits;

Four, the linking of the utility model by some devices also can be room lighting, agricultural greenhouse, industry is smelted provides the energy.

The specific embodiment

The utility model proposes a kind of heat collector that adopts concave mirror and lens to converge solar energy, be intended to overcome the existing existing problem of solar energy heat collection equipment.Adopt the utility model to use separately, use also capable of being combined, and not influenced by sunshine angle of reflection and specular scattering.

For the purpose of illustration, embodiment of the present utility model is illustrated below in conjunction with accompanying drawing.

Embodiment 1:

As shown in Figure 1, this solar energy heat collector light collecting body is a bigger concave mirror M1, is provided with a less convex lens M2 in its focus the place ahead, and they have a common focal point F 1.The parallel solar light focusing that concave mirror M1 will receive is on focal point F 1, and according to the characteristic of convex lens M2, the light that converges at F1 becomes collimated light beam after by convex lens M2.In convex lens M2 the place ahead reflector is set, this reflector is level crossing M3, level crossing M3 with beam reflection to heat collector.F1O on concave mirror M1, focal point F 1, convex lens M2, the level crossing M3 line is a primary optical axis.

Concave mirror M1 (first concave mirror) is installed in one can be made on the travel(l)ing rest of its rotation.The device of supporting plane mirror is the movable supporting that can rotate synchronously with the travel(l)ing rest of above-mentioned concave mirror M1.Like this, light collecting body can change with the angle of sunray to be adjusted, and the translation-angle reflection ray points to heat collector E all the time in any case, and the daylighting radius will not be subjected to any restriction, shown in Figure 1A and Figure 1B.
