Abstract
Great potential evaporation rate is a characteristic of areas which are seriously short of fresh water on earth. The invention adopts a method for throwing a large number of dense floating bodies on the water surfaces of reservoirs or lakes in these areas to cut off the paths through which water is evaporated into the air in order to achieve the aim of increasing fresh water in the reservoirs and lakes effectively and cheaply. Besides, the upper surfaces or the insides of the floating bodies can be provided with solar batteries to generate electricity simultaneously.
Description
Technical field
The invention belongs to water conservancy, meteorology, solar cell, environmental protection engineering field.
Background technology
It is accelerated warmer to The present invention be directed to the earth, make many areas as the NW China and the north, the big portion in Australia, the big portion in Africa, vast west Asia, middle part, North America, South America east etc., all because of severe drought, the mankind and the animals and plants necessary fresh water famine of depending on for existence has taken place put forward.
Lack problem for solving fresh water in the world, adopted measures such as reservoir filling, sewage clarification, desalinization.Also oriented reservoir is toppled over a large amount of oils the water surface is closed, avoids evaporating; Also useful floating blanket avoids evaporating and covers the scheme that plastic foamboard avoids evaporating in the water surface.
Summary of the invention
One, basic principle
Drought and water shortage area, the whole world exists all that sunlight is strong, temperature is high, the characteristics of chamber air dry." the potential evaporation rate " on these regional faces of land is all very big, such as the potential evaporation rate in the Broken Hill (Brokenshidre) in Australia area up to 2438mm; The potential evaporation rate in Tarim Basin, China Xinjiang, area, Lop Nur is unexpectedly up to more than the 3000mm.Therefore prevent that evaporation of water in these regional reservoirs or lake even the river from just can roll up the reserves of fresh water effectively.
This programme be in the big reservoir of potential evaporation rate or lake, the surface, river throws in buoyancy aid thick and fast, as much as possible and hides the water surface, cuts off contacting of water body and atmosphere.Thereby eliminated the possibility of masked area below water body evaporation, promptly be that its potential evaporation rate become is zero.Obviously its fresh water amount that reservoir is increased equals the horizontal area that buoyancy aid contacts with water and multiply by the potential evaporation rate of this area.
Meanwhile also because reservoir has been hidden very big area by buoyancy aid, the total amount of heat that makes whole reservoir draw from sunlight has reduced.Particularly after buoyancy aid has been adorned solar cell; Perhaps after the buoyancy aid upper surface of not adorning solar cell has been coated with reflecting coating, all will reduce the heat of sunlight transmission in the reservoir effectively.These all will make the average temperature on whole reservoir surface descend.Well-known potential evaporation rate will descend with the reduction of water surface temperature, and this just makes the potential evaporation rate of the area that those are not hidden by buoyancy aid also decrease.This can increase the amount of purified water of reservoir again.
Above-mentioned functions and generating by solar function all are that floating blanket vaporization prevention scheme and plastic foamboard vaporization prevention scheme are not available, so this programme has originality and structurally has novelty.
Two, the structure of buoyancy aid and application thereof
1. the like huge cushion of the profile of each buoyancy aid, its middle part need slightly microprotrusion.Also can make the cone of hanging by the feet, cone base is also slightly protruding.They are hollow, also can be solid.Can make with multiple material, as: plastics, metal, film, shell, the foam that do not absorb water, impermeable textile etc.If, will be inflated in the time of in throwing in reservoir with the hollow buoyancy aid that film is made.
2. a tightrope is equipped with in the center, below of each buoyancy aid, and it hangs down a weight, and the horizontal area that keeps buoyancy aid to hide with its weight is a maximum.Another effect of weight is may cause when preventing water surface chance wind overlapped, even is blown into aerial.
3. do not bear on the upper surface of buoyancy aid of solar cell generating usefulness or the shell reflecting coating is arranged.
4. when buoyancy aid is born the function of solar cell simultaneously if desired just the upper surface at buoyancy aid paste one deck solar cell film; Also can be in the middle of clear films or shell buoyancy aid, flatly install solar panel, make them become a solar battery cell simultaneously.The tightrope of this buoyancy aid below promptly becomes the lead of output electric energy.This root lead fixed and is delivered to electric energy the transformer station of land, is sent in the electrical network and go again by cable on the cable of a Parallel to the flow direction.
5. each reservoir can adopt the simple buoyancy aid that the water yield is used that increases according to planning, or adopts and increase the water yield also buoyancy aid of generating simultaneously, perhaps with fashionable dress with these two kinds of buoyancy aids.
Three, buoyancy aid is emitted on the form of the water surface
1. incite somebody to action a large amount of single buoyancy aids, be invested on the water surface independently.When the quantity of floating body reached dense degree, they will be as " water hyacinth " in the pond, was close to a ground for one and was arranged on the water surface.Therefore its below needs weight.
2. the buoyancy aid that has electricity generate function is fixed on the cable in the water with the tightrope (being the electric energy lead) below it, has just no longer needed weight.Their shape that is arranged in rows.
3. a plurality of buoyancy aids are interconnected and become the big row of a plurality of picture rafts.Big row's periphery is equipped with tightrope and anchor, and will be ranked greatly is arranged in reservoir.Their below has not just needed tightrope and weight yet.
The benefit estimation
Increasing the economic benefit of the water yield about buoyancy aid can be simply and estimate as follows more exactly.
1. the potential evaporation rate of establishing certain Reservoir Area is 2000mm=2m water column/every year.Therefore area of every input is 1m
2Buoyancy aid in reservoir, the annual pure water that just can increase by 2 cubic metres.
The life-span of supposing each buoyancy aid is 5 years, and then it has just created 10 cubic metres water for reservoir in 5 years.
Suppose each buoyancy aid make and installation cost is 4 dollars.Therefore the cost of production of every cubic metre of water is: 4 dollars/10m
3=0.4 dollar/m
3
By the file introduction: the cost of production of every cubic metre of water of U.S.'s desalinator is 1～4 dollar.The economic benefit of hence one can see that this programme is far above desalinization, purification of waste water.
2. the estimation approach that also has a simple and intuition: be exactly when the vanishing of potential evaporation rate, just mean that every year, the fresh water of increase improved 2m to reservoir level.If consider that the buoyancy aid masked area only for 80% of the reservoir water surface, also equals reservoir level has been improved 1.6m.
If the average length of certain reservoir * wide=10km * 0.5km=5km
2=5 * 10
6m
2That is to say that this reservoir can be the resident and provides 8 * 10 more every year
6m
3Pure water.
3. above estimation does not comprise that also the reservoir water surface temperature reduces, and makes 20% the water surface that does not hide reduce the amount of purified water that increases because of the potential evaporation rate.
Embodiment
All parts of the present invention all belong to mature common used material and element, therefore are easy to realize.
