Because a large amount of burning fossil energies have caused global environmental pollution and ecological disruption, and human existence and development are constituted a threat to.Nineteen ninety-five State Planning Commission, State Scientific and Technological Commission and State Economic and Trade Commission formulated " new and renewable sources of energy development outline " (1996-2010), developing goal, task and corresponding countermeasure and the measure of China at the 1996-2010 new and renewable sources of energy clearly proposed.The formulation of these files and enforcement have been brought into play important function to further promotion China solar energy cause.

At present, solar energy has obtained certain application in a plurality of industries, the single lens of general employing are gathered solar energy, because single lens have certain limitation to the collection of energy, the finite energy that collects, can not satisfy the wilderness demand of people to energy, especially generating waits the sharp at all have more than is needed solar energy of industry that needs lot of energy just can carry out, and makes people obtain very big restriction to the utilization of solar energy; In addition, the general focal length of lens that adopts is longer, and lens are levels always, so energy is not just concentrated under the solar day situation big according to gradient, the energy collected of solar cell is just very limited like this; The finite energy that the solar cell of certain area is collected; The basic individual layer that adopts is gathered lens, area one regularly focal length short inadequately, take up room big.

So, how to adopt effective method to realize a large amount of collections to solar energy, the needs that make solar energy can satisfy all industries become the important topic of International Energy Agency and developer's research.

[summary of the invention]

The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of solar energy collecting plate, can collect a large amount of solar energy, satisfies the energy requirement of different industries to solar energy, makes solar energy can be applied to all trades and professions.

For achieving the above object, the utility model proposes a kind of solar energy collecting plate, comprise collection plate and the some lens that are arranged on the collection plate.

Further, lens adopt Fresnel Lenses.

Further, lens become array to arrange on collection plate.

The beneficial effects of the utility model: the utility model adopts a solar energy collecting plate, on described solar energy collecting plate, be arranged with the Fresnel Lenses of several collecting energies, the corresponding solar cell of each Fresnel Lenses, again the collected energy of all solar cells is assembled, like this, the energy that collects simultaneously is just very big, and obtain bigger energy if desired, the quantity that only needs to increase Fresnel Lenses just can realize easily, can satisfy the requirement of industry-by-industry to the energy size, make the energy of this cleaning of solar energy obtain utilizing very fully, the human energy and environmental science aspect are had epoch making significance; In addition, the utility model can be done focal length shorter, and energy also can be concentrated relatively when sunlight was casted oblique rays on; Also can be furnished with synchrotimer, like this solar day according to the big situation of gradient under energy also can be concentrated relatively, realized the small size macro-energy; The cost of whole collection plate is low, and the energy of being gathered behind the solar silicon photovoltaic cell adapted collection plate of same area is original tens of times even more times; Two or more collection plates can also be carried out compound use, to realize the collection of short focal length macro-energy.

Feature of the present utility model and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.

[description of drawings]

Fig. 1 represents the structural representation of the utility model solar energy collecting plate.

[specific embodiment]

Be illustrated in figure 1 as the structural representation of the utility model solar energy collecting plate; Comprise collection plate 1 and the some lens 2 that are arranged on the collection plate 1.1 pair of material of described collection plate does not have special requirement, can adopt common anti-aging material.Be arranged with some lens 2 on collection plate 1, lens 2 are used for gathering solar energy, each lens 2 corresponding solar cell, and solar cell is collected the energy that collects, and the solar energy of collecting is assembled, and has so just formed very big energy.Suppose that original lens can only collect the energy of 100J one second, if be arranged with 9 lens 2 now on collection plate 1, the energy that collects a second is exactly 900J so, is original 9 times, bigger if desired energy only need be arranged more lens 2 on collection plate 1.
