Abstract
A light-gathering solar engine is composed of external cylinder sleeve, internal rotor, several sliding plates, two end covers and bearings in the downward eccentrical hole on end cover for the internal rotor. An air-tight cavity is formed by several slide plates radially installed on rotor, internal surface of external cylinder sleeve and two end covers. The air coming into the said air-tight cavity is compressed at lower stop point, where is absorbs the heat of focused sunlight and then expanded at upper stop point to do work, so converting solar energy to mechanical energy. It is suitable for compressor of air conditioner, electric generator, etc.
Description
The present invention relates to a kind of light-gathering solar engine.
At present, the development and use of solar energy are general with the solar water heater, but solar energy will be transformed into mechanical energy, at present still in the exploratory stage.
Purpose of the present invention is at above-mentioned blank spot, and a kind of light-gathering solar engine that makes solar energy directly be transformed into mechanical energy is provided.
To achieve these goals, light-gathering solar engine of the present invention is by the following technical solutions: the sunlight of certain direct projection area is pooled focus with parabola shaped reflecting surface, and the focus that can produce high temperature is projeced into the lower dead center cylinder sleeve external surface partly that air compression ends, thereby make a part of cylinder sleeve bulk absorption heat of projection place, and this heat passed the pressurized air be in contact with it by cylinder bore wall in cylinder sleeve, at this moment, this air is because heat absorption and pressure rises, and then is that the air of heat absorption is crossed after bottom dead center expansion working and is transformed into mechanical energy.Its structure mainly is by the outer shell body, internal rotor body and be located at some rectangle slide plates on the internal rotor body and compositions such as left and right sides end cap, bearing.The center of circle of the described internal rotor axon heart and outer shell body is eccentric down, described slide block can radially slide on the internal rotor body, and under radial spring elastic force and rotation action of centrifugal force, touch with outer shell body inwall normality and to close, the inner side plane of two limits and two end caps is touched respectively and is closed about the while slide block, promptly form several fan annulated column shape confined chambers, along with the rotation of internal rotor, each can obtain the volume of each confined chamber shrinking and to the process of top dead center expansion to lower dead center.The expansion chamber maximum be top dead center clockwise slightly partially to the position about have relative air on two end caps and change the hole, two axle heads of internal rotor are engaged on the relative bearing hole of the off-centre two end cap centers of circle under with bearing respectively.
The conversion process of energy of solar engine of the present invention is: with external force internal rotor is started rotation earlier, by carrying blower the cold conditions air is blown into the fan ring cylindrical room relative with this hole from left end air replacing hole then, rotation along with internal rotor, can be with the interior position of air compression to projection place of lower dead center sunlight focus, if compression ratio was with 3.8: 1, the air self temperature that compression ends can rise to the 150-205 degree, pressure is 4-5 barometric pressure, the words of temperature design about 600 degree as projection place of sunlight focus, so compressed air heat absorption back temperature can rise to more than 400 degree, pressure increases to about 6.9 barometric pressure, enter expansion place through after bottom dead center High Temperature High Pressure air then and expand and promote slide plate, be about to heat energy and be transformed into mechanical energy.Each can take turns periodic duty successively several confined chambers.
The present invention compared with prior art has the following advantages:
1, can make solar energy directly be transformed into mechanical energy.
2, this machine is simple in structure, and frictional loss is little, and because the air after the compression passes, heat absorption capacity is good, therefore, the thermal conversion efficiency height.
3, this machine-processed fabrication technique is simple, cost is low, has broad prospects for the exploitation of following green energy resource.
The present invention is suitable for the power adapted of air conditioner compressed device, generator and field work machine.
The present invention is described in further detail below in conjunction with drawings and Examples.
Figure one is the overall supporting cut-away view of light-gathering solar engine of the present invention; Figure two is working principle axis of no-feathering sectional drawing of the present invention.
Shown in figure one, the present invention is by some cuboid slide plates 4 that can radially slide on left end cap 2, outer shell body 6, internal rotor 5 and the internal rotor 5 and right end cap 7, add again left and right sides bearing of not drawing in the drawings etc. form.Be provided with inlet hole 1 on left end cap 2, same right end cap 7 is provided with the exhaust port relative with left end cap inlet hole 1; Also respectively be provided with on the end cap of the left and right sides with its center of circle under eccentric bearing hole relative to each other 3.
Shown in figure two, outer cylinder sheath 7 inwalls and adjacent two slide plates 5 and internal rotor 4 side faces and two end cap inner side plane can be formed fan annulated column shape confined chamber 11, along with clockwise rotating of internal rotor 4, each slide plate 5 each can be in this slideway 1 by centrifugal force and casing wall to thrust is reciprocatingly slided, by the radial spring in the slideway 1 (letter is drawn in the drawings) slide plate 5 bullets are closed to touching with outer cylinder sheath 7 inwalls when static, after external force starts rotor 4 rotations, the cold conditions air is under the effect that carries blower, after entering from inlet hole 10, through between the compressing area 9 to the compression of the seat of sunlight focus projection place 6 of lower dead center, this pressurized air absorbs the solar heat energy that transmits by cylinder bore wall and temperature raises then, pressure increases, change 2 expansions between expansion regions afterwards over to, promote slide plate 5, internal rotor 4 is rotated.Each confined chamber 11 can take turns successively from the periodic duty process of compression---heat absorption---work done.In the course of the work, the sliding surface of rubber weather strip 3 salable slide plates 5, heat insulation layer 8 can cut off the biography mistake of heat.The present invention is suitable for air conditioner compressed device, the power adapted of generator and field work machine.
