Description

A kind of stratosphere suspends and inflates the platform solar power plant

Technical field

The utility model relates to a kind of stratosphere suspension inflation platform solar power plant, especially is suspended in atmospheric stratospheric inflation platform solar power plant with hawser control.

Background technology

At present, the solar power plant is based on the surface power station, but, it almost is impossible building the large-sized solar power station on the ground in a large number, reason owing to weather, all there is sufficient sunlight in not all area, and for the originally very nervous mankind of land resource, can not take out a large amount of land developments solar power station in large scale, the desert that does not just have much values at last, also can't escape from wind, cloud, thunder,, ice, frost, snow, rain, the influence of climatic factors such as sandstorm, the desert generally apart from the mankind yard up far away, the input/output line road is long, and solar power station that neither be very desirable is built ground, and all there is husky film not all countries and regions.So, numerous scientists have invested space to sight: move the solar power plant to the sky, from universe, gather solar energy, promptly utilize geostationary satellite to absorb solar energy and generating in orbit, pass electric energy back the earth with the form of microwave or laser then, this is a very perfectly imagination, but, owing to the high launch cost and the reasons such as technical problem of electric energy transmitting, rest on the imagination stage, practical at present aerial solar power generation mainly is used in aspects such as artificial satellite, spaceship, solar energy flight test vehicle always.In the distance ground level is atmospheric advection layer about the 10-50 kilometer, cloud layer is difficult to arrive this height, the sun shines about 12 hours every day, about 4300 hours hours of daylights of year, here air drying, dust and steam are seldom, Atmospheric Flow is steady, almost there is not the influence of pernicious gas, this is the ground of the ideal of near-space solar power generation, so the someone proposes the conception of stratosphere solar power plant very early, building solar power station at stratosphere compares with the earthbound solar energy power station of same scale, the solar energy that receives will exceed 5～10 times, though it is shorter than the hours of daylight on the geo-stationary orbit, but it is very near apart from ground here, the most only about ten kilometers, electric energy can directly transmit with lead, transmission means than the geo-stationary orbit power station is much simple, electric energy transmitting efficient is much higher, construction cost is much lower, security implication to ground is much smaller, and management maintenance is much easier, and the someone imagines and uses balloon, inflation platform or dirigible are loaded onto solar cell, just can generate electricity and carry earthward with lead, common balloon poor reliability, solar cell is installed difficult, because intensity of illumination is inhomogeneous, coupling is difficult between battery, the common hawser that connects between ground and the balloon is subjected to windage big, so the stratosphere solar power station is the same with satellite geo-stationary orbit power station, still rests on the imagination stage at present.

Summary of the invention

For making the human first time, the deficiency that overcomes the stratosphere solar power station in the imagination use the stratosphere solar power generation to become a reality on the ground; it is the inflation platform solar power station of almost plane that the utility model provides a kind of upper surface; electric energy can directly pass to the ground current conversion station by lead; become alternating current again and enter supply network; human use's stratosphere solar power generation is become a reality, for breaking away from energy crisis in the human short time and environmental pollution provides a solution.

The technical scheme that its technical problem that solves the utility model adopts is:

Adopting upper surface is the inflation platform of almost plane, its upper surface is equipped with solar cell, main push-towing rope rope one end is connected in the hawser below the inflation platform, the other end is fixed on the hawser fixing point of ground, the inflation platform be positioned at cloud layer above, under the irradiation of the sun, solar cell produces direct current through the anodal output line of solar cell, solar cell negative pole output line is delivered to the ground current conversion station, after the process current conversion station becomes interchange with direct current, electric energy is sent the anodal output line of solar cell by exchanging outlet line, solar cell negative pole output line is fixed on the circuit anchor clamps of main push-towing rope rope.Platform is put into apart from ground flat fluid layer space, and preferably about 18 kilometers, the there wind speed is very little, and atmospheric density is also little, and it is insignificant that the strength of wind just seems, only considers the influence of hawser wind-engaging; Because the pulling force that is subjected to more above of main push-towing rope rope is big more, can make main push-towing rope rope cross section with highly increasing, and uses small top and big bottom hawser.

Embodiment

In the accompanying drawings, upper surface on the inflation platform 1 is an almost plane, solar cell 2 is installed on it, main push-towing rope rope 3 one ends are connected in the hawser 6 below the inflation platform 1, the other end is fixed on the ground hawser fixing point 11, the inflation platform 1 be positioned at cloud layer 10 above, under the irradiation of the sun 12, solar cell 2 produces direct current through the anodal output line 4 of solar cell, the electric current of solar cell negative pole output line 5 is sent into current conversion station 8 near delivering to ground then, after process current conversion station 8 becomes interchange with direct current, by exchanging outlet line 9 electric energy is sent the anodal output line 4 of solar cell, solar cell negative pole output line 5 is fixed on the circuit anchor clamps 7 of main push-towing rope rope 3.Platform is put into apart from ground about 18 kilometers stratosphere space, and the there wind speed is very little, and atmospheric density is also little, and it is insignificant that the strength of wind just seems, only considers the influence of hawser wind-engaging.

The structure choice and the manufacturing of inflation platform: as long as the upper surface almost plane, other several times shapes are inessential, its building technology and how to rise to stratosphere can be with reference to dirigible or large balloon technology, these technology are very ripe at present, do not describing in detail here.

The selection of gas: from economic angle, hydrogen is desirable selection, though the poor stability of hydrogen is a little because platform operates in stratosphere, above rarefaction of air, only be 1/tens of ground, use the fail safe of hydrogen more much higher than ground, just in case occur leaking, face rings minimum over the ground, from security standpoint, helium is optimal gas.

The selection of solar cell: in order to reduce battery weight, select thin-film solar cells for use, also can use up-to-date can make the technology of solar cell " printing " at the balloon upper surface weight of solar cell reduce many.

The main push-towing rope rope is selected: the key of the utility model success is the main push-towing rope rope, so the selection of main push-towing rope rope is very important.The high ladder imagination that the scientist of the former Soviet Union put forward in 1895,2000, the notion of building the space elevator was described by NASA, and this hawser that needs superfine carbon fiber to make also can extend to 36000 kilometers of terrestrial equator tops.The length of the utility model main push-towing rope rope is 18 kilometers, than short about 2000 times of high ladder scheme cable length, also select the carbon fiber hawser for use, can satisfy weight fully, the requirement of intensity, such as the pulling force that has a kind of carbon fiber hawser to bear now is about 17 tons/square centimeter, has the intensity height, corrosion-resistant, the aging-resistant characteristics, in order to reduce the influence of wind-force as much as possible, present embodiment only uses a hawser, according to the pulling force difference that the hawser differing heights is subjected to, top more stressed big more, following more stressed more little characteristics, hawser is processed into the bottom section to be amassed little, the hawser top cross-section is amassed big shape, promptly satisfies force request economical with materials again to reach, alleviate hawser weight, reduce the purpose of wind-force to the active force of hawser.

The selection of lead: because every conductor length is 18 kms, must consider the lead deadweight, selecting aluminum steel is the electric energy transmitting lead, and lead can be fixed on the hawser, is born the part weight of lead by hawser.

According to long-term meteorological record data, the area of selecting meteorological condition better relatively (wind-force is less throughout the year) is as the place of building stratospheric inflation platform solar power plant, manufacturing platform on the ground, can be with reference to dirigible or large balloon technology, barometric control unit also adopts the technology of dirigible, no longer describe in detail, different is to lay solar cell at the balloon upper surface, solar cell lays on the ground and finishes, preferably use up-to-date solar cell manufacturing technology, the upper surface of solar cell " printing " at balloon; The balloon of building up that has solar cell is connected with hawser with the aluminium output line is connected; Select a date that the fine atmosphere of weather is calm or wind-force is less, a balloon is put in the air, hawser and output line is raised to stratosphere by the buoyancy band of balloon self, one end of hawser is fixed on the ground, introduce the ground current conversion station with output line and just can obtain stratospheric electric energy, cause the power station problem of unstable about wind-force, present embodiment has been selected the carbon fiber hawser, intensity is not problem, just very under the opposite extreme situations, when any place's wind direction of hawser is all identical, the power that is subjected on the main push-towing rope rope is also not very big, but extreme case can not occur substantially, because endoatmosphere at 18 kilometers thickness, make each height wind speed maximum and direction identical, be impossible, actual conditions are that the speed and the direction at each height of air-flow is different, direction and size variation impermanence, for example highly being 3 kilometers, to locate wind speed be 10 meter per seconds, east wind, the aerial wind speed that highly is 10 kilometers is 13 meter per seconds, west wind, hawser has nothing in common with each other in the wind-force size direction that differing heights is subjected to, and the surplus that the back of cancelling out each other produces just impacts the power station, and this influence also is limited, because the power station of present embodiment and traditional hydroelectric station, there is the difference of essence in thermal power station, and very light, do not have mechanical moving component, so because of wind-force make balloon all around move up and down for the generating influence very limited, also may influence solar radiation intensity, thereby influence variations such as electric current and voltage, but these variations being in accordance with expectation, is acceptable.
