Description

Solar generator

Technical field

The utility model belongs to a kind of generator, especially refers to a kind of generator that power is provided by solar energy.

Background technique

Generator set of the prior art comprises steamer formula generator set, and it produces electric energy by making high temperature or low temperature gas by Turbo-generator Set.Yet because steamer formula generator set general cost is higher, therefore complex structure generally is unsuitable for family and uses.In addition, under the situation that family uses, the producing method of the steam that driving steam turbine rotates also is a problem.

The model utility content

A purpose of the present utility model is to solve deficiency of the prior art, and a kind of solar generator is provided.

For achieving the above object, solar generator of the present utility model comprises

Solar steam generating device comprises light collecting device, and water tank, and described tank shell has the light transmitting part, water intake and steam-expelling port, and the middle part is provided with heat absorber, and the focus of described light collecting device falls within heat absorber by described light-transmitting portion;

Steam turbine comprises the cylinder body with steam inlet and steam-expelling port, and is positioned at first rotating shaft and second rotating shaft between cylinder body inside admission mouth and steam-expelling port, and first impeller and second impeller that are fixed on first rotating shaft and second rotating shaft respectively; Wherein, described steam inlet is coupled to the water tank steam-expelling port;

Be coupled in the generator unit of first rotating shaft and second rotating shaft; And,

Be coupled in the energy storage device of generator unit.

Working principle of the present utility model is as follows: light collecting device makes sunlight converge, the light beam that pools is by the heat absorber in the described light-transmitting portion irradiation water tank, heat absorber and then the heat that absorbs is used for heating water contacted with it, water temperature raises until producing steam immediately, because water changes the steam state volume into from liquid state and expands rapidly, cause vapour pressure rising in the water tank, the high pressure gas goes out steam port from water tank and flows out, enter from the steam inlet of steam turbine, flow out from steam ouput, in this process, do work, first rotating shaft and second rotating shaft of driving steam turbine relatively rotate, and two rotating shafts drive the generator unit generating that couples with it respectively, and the electric energy that generator unit produces is stored in the energy-storage units immediately.

The beneficial effects of the utility model are that product structure is simple, and cost is lower; The environmental problem of utilizing solar energy can avoid traditional coal combustion fry dried food ingredients electricity etc. to produce.

Embodiment

The utility model relates to a kind of solar generator, in order to realize generating with lower cost, below in conjunction with accompanying drawing, feature of the present utility model is elaborated:

Fig. 1 is a systematic schematic diagram of the present utility model, and with reference to Fig. 1, solar energy steamer formula generator of the present utility model comprises light harvesting unit 1, water tank 2, steam turbine 3, generator unit 4 and energy-storage units 5.With reference to Fig. 2, light harvesting unit 1 comprises support 10 and convergent lens 11, with reference to Fig. 3, water tank 2 has a light-transmitting portion 21, this light-transmitting portion 21 is arranged between convergent lens plane, 11 place and its plane, focus place, the middle part of water tank 2 heat absorber 22 that can be connected can be bar-shaped, and this heat absorber can be made by the high ferrous metal of thermal absorption efficient.Preferably, convergent lens 20 can be set, its focus is fallen within on the heat absorption rod 22.With reference to Fig. 3, water tank 2 also has water intake 23 and steam ouput 24, and wherein water intake 23 connects outside water source, and steam ouput 24 connects the steam inlet of steam turbine 3.

With reference to Fig. 4, steam turbine 3 generally has a housing 31, is respectively equipped with steam inlet 311 and steam ouput 312 at the object two ends, and

impeller

321 and 331 also are connected respectively in also be connected on the housing first rotating shaft 32 and second rotating shaft, 33, the first rotating shafts 32 and second rotating shaft 33.Fig. 5 a to 5e shows the turbine work flow process.With reference to Fig. 5 a, the high-temperature steam that water tank 2 produces enters in the housing by steam inlet 311, its impeller 321 clockwise rotates, with reference to Fig. 5 b to 5d, under the effect of the steam steam flow that continues, impeller 321 is pushed and prolongs and clockwise rotates, the impeller 331 that drives second rotating shaft simultaneously rotates counterclockwise, at last, with reference to Fig. 5 e, gas is discharged outside the housing by steam ouput 312.In this process, the high-temperature steam steam temperature descends, kinetic energy loss.First rotating shaft 32 of steam turbine and second rotating shaft 33 under the drive of impeller separately respectively along clockwise and be rotated counterclockwise.

With reference to Fig. 1, first rotating shaft 32 and second rotating shaft 33 are coupled respectively at a generator unit, have driven generating, and here, the structure of generator unit 4 and purposes are well known in the prior art.The electric energy that generator unit 4 produces can store by energy storage device 5, and such energy storage device can be as the capacitor of having known in the prior art etc.
