Abstract

The invention provides a solar energy photoelectric bubble generating device which is a device converting solar energy to electric energy directly. The invention is characterized in that: a spherical involute curved surface concave mirror focuses sunlight to a focus; the sunlight is reflected by a spherical involute curved surface convex mirror (or the concave mirror) to form parallel light beams; the light beams are emitted to a convex lens of a photoelectric bubble installed at a central hole of the spherical involute curved surface concave mirror, and are focused again through the convex lens to form bright light of seven or eight thousand times; the bright light is emitted to a photoelectric conversion plate K (also called cathode ); under a superposition effect of a photoelectric effect and a thermal ionization principle, the photoelectric conversion plate emits strong electron flow; inside space of the bubble is in high vacuum, K and A are connected with low voltage to establish an electric field, and under an effect of applied electric field force, the electron flow flies to an anode N to form an electric current in a closed external circuit. The device can be applied individually or applied with array combination. It is estimated that photoelectric conversion efficiency of the device can reach about 30%-40%. Largest advantages of the device are low cost and high efficiency, and solar energy can be effectively utilized.

Description

The generating of solar photoelectric bubble

Technical field

Solar energy is directly changed into utilization of power.

Background technology

Sunlight is one of the finest human unredeemed hope as using energy source.Photovoltaic generation and the tower generating in the thermal electric generator, the generating of dish formula, slot type that present global solar energy generation technology has solar energy to be directly changed into electric energy generate electricity, and also have stack effect generating etc.But all because of the cost height, efficient is low, and the electricity price height does not have commercial competitiveness.So, must fully expand the unique advantage of sunlight, out-of-the-way path in addition, this just expedites the emergence of photoelectricity bubble generation technology of sunny energy.

Summary of the invention

The photoelectricity bubble generation technology of solar energy is to utilize sphere shape involute surface concave mirror that sunlight is arrived focus, be reflected into directional light by the little convex lens of sphere shape involute surface (or concave primary mirror) again and inject the convex lens that photoelectricity steeps, focus on once more, be mapped on the photoelectric conversion plate, become electric energy to spread out of transform light energy.Particular content has 3 points.

1, the design of sphere shape involute surface concave mirror.Through mapping analysis, see accompanying drawing 1, the sphere concave mirror is not the light that is parallel to main shaft to return on the point that is mapped to real meaning, but reflexes on one section line segment of main shaft.Because of to ask the calculating formula of focal distance f is a functional equation, f=R-0.5R ÷ COSa (f is a focal length in the formula, and R is a spherical radius, and ∠ a crosses the spherical radius of any 1 A and the angle of main shaft on the sphere).Concrete derivation is omitted.Become real directional light not realize with concave primary mirror or little convex lens assembling sunlight reflected like this.Must transform the sphere concave mirror, make its optical convergence to real point, above-mentioned functional equation is become The value that makes f is definite value (the f value of getting on the concave mirror centre bore edge point is a definite value), calculates with angle a value is pairing and leaves on the generating circle at every

Numerical value, (sphere in the full scale equation is called the generating circle sphere, cross the garden that the plane of the centre of sphere cuts out and be called generating circle), form involute, with the main shaft is that rotating shaft rotates, by the curved surface that involute path forms, be called sphere shape involute surface, the concave mirror made from such curved surface is called sphere shape involute surface concave mirror.Essence is in the normal direction of adjusting on the sphere at every, and it is reflexed to sunlight on the point of a real meaning.Concave primary mirror or little convex lens are also followed the prescribed rules.Device through the combination of improved concave mirror and little convex lens (or concave primary mirror) can be reflected into directional light with sunlight, can reach the purpose that focuses on once more after entering convex lens.

2, the design of photoelectricity bubble.See accompanying drawing 2.The photoelectricity bubble is the device that solar energy is directly changed into electric energy.Using for reference Roentgen ray tube successful design method, design the opto-electronic conversion bubble, make luminous energy be directly changed into electric energy, is a kind of back reaction device.Among Fig. 2, M is convex lens, and K is a photoelectric conversion plate, also is negative electrode, and N is a collector electrode, and K, N make with tungsten, and A is an anode, isolates with mica sheet between N, the A, makes it insulation.Be pumped into high vacuum in the bubble, give K and A logical low tension, set up electric field.When high power concentrator shone on the K, instantaneous had electronics to fly out, and is photoelectric effect, when K was heated to red heat, the outermost electronics of atom obtained enough energy and ionization takes place, under the effect of electric field force, electron stream flies to the N level by K, and transform light energy has been become electric energy.The temperature of K plate is high more, and the electronics of ejaculation is many more.When the energy that obtains when the K plate and the energy of ejaculation equate (electronics and light energy sum), temperature no longer raises.When temperature reduced, the energy of ejaculation also reduced thereupon, and this is the self-regulated character of its instinct.Visible light is that the outer-shell electron by atom is excited and the light that produces.Remove directly to add the outermost electronics of hot atom with the poly-sunlight of high power now, make its ionization, form electric current, luminous energy is directly changed into electric energy.Via external circuit pass back because of having made the low-energy electron that merit reduces energy, lost the former muon capture of outermost electron, enter the thermal ionization that adds of a new round.This is the exclusive characteristic of sunlight, and other energy can't directly be accomplished.Because the effect of photoelectric effect mechanism and the stack of thermal ionization mechanism makes its photoelectric conversion rate height, estimation can reach about 30%---40%.Because there is part light to be reflected, can not enter convex lens, the light that enters the photoelectricity bubble exactly has considerable part to penetrate the photoelectricity bubble with the form of light again.In order to reduce above-mentioned loss, can add some reflection measures and plate film to convex lens, reduce this loss, improve the transmitance of converging light.Plate reflectorized material for the glass inwall of conversion bubble, light is reflexed on the change-over panel once more, add hot electron, improve transfer ratio.

3, single unit system is seen accompanying drawing 3, and sphere shape involute surface convex lens is installed in the below of sphere shape involute surface concave mirror focus, and virtual focus and focus are overlapped fully.Photoelectricity steeps (concave mirror, convex lens are called for short in the back) on the centre bore that is installed in sphere shape involute surface concave mirror, and the main shaft of concave mirror, convex lens (or concave primary mirror is above focus), convex lens overlaps fully.Be subjected to the control of automatic control equipment, the main shaft of concave mirror remains parallel with sunlight.Sunlight can reach seven, 8,000 times through twice convergence, even up to ten thousand times.Can be heated to 2000-2500 ℃ with photoelectric conversion plate is instantaneous, make the outermost electron ionization of atom, directed movement under the effect of electric field force flies to collector electrode, produces electric current.Be equipped with electric energy storage device, power supply when not having sunlight.

The item that it should be noted that is this device when turning round, and external circuit must have load, keeps the circuit closure.Otherwise when external circuit was not closed, the atom that loses electronics on the photoelectric conversion plate can not get replenishing of electronics, and temperature can continue to raise, and photoelectric conversion plate Yin Wendu is too high, and the danger of being burnt is arranged.
