Description

Solar generator

Technical field

The utility model relates to the electric power output unit, specifically, relates to a kind of novel electricity generator that utilizes solar energy and steam engine principle.

Background technique

Energy problem is the current and following matter of utmost importance that is restricting human development, because oil, these non-renewable resources of coal have exhausted one day eventually, and its pollution problem is also serious day by day, therefore how to utilize renewable, free of contamination novel energy just generally to be paid attention to by people institute.Utilize more relatively novel resource mainly to comprise waterpower, wind-force and solar energy at present.But the height of the cost of the required early investment of hydroelectric power need not many speeches, and equipment such as the required blower fan of wind-power electricity generation and the required solar panel of solar electrical energy generation all also belong to the very expensive equipment of cost, its cost of production and user cost are all than higher, and the difficulty that popularizes is bigger.

The model utility content

The purpose of this utility model is cost height renewable at having now, that non-polluting energy sources generation equipment exists, promote difficult deficiency, provide a kind of conversion of solar energy of utilizing to be heat energy, again heat energy is converted into mechanical kinetic energy, and finally be converted into the novel solar power generation machine of electric energy by mechanical kinetic energy.

The technical solution of the utility model is: a kind of solar generator comprises a solar heat collector, a heat-exchange gas evaporating plant, a steam expansion motor, and a permanent magnet generator; Described solar heat collector comprises a solar bracket plate, supporting plate is provided with a plurality of glass-vacuum tubes, all be provided with heat exchanging tube in each vacuum tube, and the heat exchanging tube in all glass-vacuum tubes all is interconnected, and the pipeline that is communicated with is by the heat exchange steam generator, the heat exchange steam generator is connected by pipeline with the steam expansion motor, and permanent magnetic engine joins by distribution box and extraneous electrical network.

Preferably, the pipeline between described heat exchange steam generator and the steam expansion motor is provided with gas holder.

Preferably, be provided with air pressure regulator between described gas holder and the steam expansion motor.

Preferably, described steam expansion motor comprises a cavity, at least two piston rods are set in cavity, and the bent axle that is connected linkage with piston rod, piston rod all is placed in independently in the cavity, each cavity all is provided with intake valve and exhaust valve, and an end of bent axle connects flywheel, and the other end connects the valve controller for opening and closing.

Preferably, described valve opening and closing device comprises that is installed in bent axle one an end drive chain, and the valve camshaft that is driven by the transmission chain case, and valve camshaft is controlled the switching of intake valve and exhaust valve on each cavity.

The beneficial effects of the utility model are: solar energy heating has been a kind of comparatively mature technique, the heat that utilizes sun the subject of knowledge and the object of knowledge to produce adds hot water and produces steam, utilize the steam driven motor again, cooperate with generator by motor at last and produce electric energy, the device of the required usefulness of complete equipment all has comparatively ripe production technology, manufacture cost and generating are also lower, and are convenient to safeguard and promote.
