Description
One, technical field
The present invention relates to the utilization of marine resources, manually make the seawater space, the potential energy of seawer tide is transformed into the hydraulic power project of electric flux.
Two, background technique
Current, use multipath electrogenesis in next life energy such as waterpower, firepower, wind-force, chemical energy, solar energy, nuclear energy and morning and evening tides.But bring the various insoluble problems such as warm of loss, the weather of pollution, the water and soil of the exhaustion, appropriation of land of resource, ecological destruction, environment, and the harm of hiding such as flood, nuclear radiation.
" power generation with sea water station " utilizes the potential energy source of the seawer tide that attraction force produces that inexhaustible, the nexhaustible marine resources of nature favor and the moon sends here the earth, makes it to become electric flux.Her generation will have outstanding meaning to contribution to society, because of she is a valuable energy that is not never disappeared by the real utilization of the mankind, be the most potential a kind of clean renewable energy sources.
" power generation with sea water station " is multi-functional project, and existing production electric energy function has harbour transportation function, reservoir area mariculture function and Baywatch amusement and travel function again.If financial resources allow, can build several " power generation with sea water stations " along the shore line connection.The big dykes and dams in reservoir area are " the marine Great Wall " of resisting the tide natural disaster, are again the places of coastal traffic main line and sea wind generating.
" power generation with sea water station " with under the prerequisite that does not influence military and course line, according to country's decision-making, scientific and normal, very long wide wide shore line and bay can be built everywhere, and scale is changeable.Build with material (as stone, earth, cement, steel etc.) simply, manufacturing mechanism (as generator, water wheels unit etc.) is easily purchased easy system.What a difficulty was arranged in the construction is the reservoir area dam of building in the greater coasting area of shore line, the one, and operation at sea, the 2nd, the requirement dam is stood the impact test of violent typhoon and wave more than 12 grades.But its technical difficulty is compared with Other Engineering (as marine reclamation land, Three Gorges Dam, Donghai Bridge in Shanghai), and it counts nothing at all, and modern construction technique has the ability to make her " to turn one's dream into reality " fully.
Because seawater contains silt, after the several years, the sedimentation meeting shoals the reservoir area, can siphon away silt with hydraulic suction dredge.If do not take measures, the mariculture function that also just disappears, electricity generate function can not disappear.
" power generation with sea water station " is the matter of fundamental importance in thousand.Though engineering is bigger, it is more to inject capital into, and it is long-term investment, one-time investment, long-time income, income by all kinds of means.No matter what state has any to affirm, obtain the interests basic assurance: its energy sources is eternal, and is free, safety.
Three, summary of the invention
Seawater is subjected to pining down of moon attraction force, and producing periodically, morning and evening tides (tidal bulge, ebb, tide are put down) changes.Along with the variation of the moon to earth operating angle degree, morning and evening tides time and fluctuation water-head are apart from also and then changing.Little torrent water-head distance is about more than 5 meters, about about 12 meters of big flood tide water level gap." power generation with sea water station " is exactly the potential energy of managing how to obtain this water-head distance more than 5 meters, at the round-the-clock production electric energy in torrential big sea.
Its method is:
1. set up production site
Build production site at the shore line greater coasting area.The power station is made up of between the big reservoir area of two area considerable scales and water wheels unit, variable transmission mechanism, generator car and water flow controlling operation room etc.
A reservoir area (first reservoir area) is used for retaining, and several electric gate valves (A gate group) are housed on the dykes and dams.Several electric gate valves (B gate group) also are equipped with in the seawater space that another reservoir area (second reservoir area) is used to sluice on the dykes and dams.Second reservoir area area is greater than two times of first reservoir area area.
Between generator car and water flow controlling operation room is built in the middle of first, the second reservoir area on the dykes and dams, is water wheels unit and variable transmission mechanism below the dykes and dams.
2. obtain the ocean potential function
Open the A gate group and the B gate group of first, second reservoir area, the water that forms two reservoir areas is connected with storehouse Wai Shui (sea).No matter seawater tidal bulge, ebb and tide are flat, the water level of two reservoir areas keeps same water line with the sea.
When tide at ordinary times, seawater is lowest water level (being referred to as 0 of sea horizon temporarily), shuts B gate group, makes the water level of second reservoir area be in the lowest water level line, has formed the seawater space.Equally, when seawater increases to highest water level, shut A gate group, the water level of first reservoir area is in maximum water level.At this moment, we have just successfully obtained the potential function of seawer tide, and first reservoir area that just can the impulse water turbine running exceeds water-head more than 5 meters than second reservoir area.
OK, the water-head of first, second reservoir area has been arranged, the sluicing space of enough water retention capacitys in first reservoir area and the enough areas in second reservoir area has been arranged, just can generate electricity.Current with the first reservoir area flow into the second reservoir area behind the impulse water turbine continuously.Turbine blade obtains making the water turbine running after the impact force, thereby drives generator for electricity generation.
But much no matter first, second reservoir area area has, through behind the certain hour, the first reservoir water level has descended, and the second reservoir water level has raise, and water-head does not have, and can not generate electricity.Have to reopen A, B gate group, wait for that tide is flat, tidal bulge ...
Is not certainly the someone understands query: this intermittent power generation exactly the tide power station? can the power that obtains satisfy the requirement of generating? we say: " power generation with sea water station " is not the tide power station, and the two has basic difference.
First point: tide power station addressing difficulty, and " power generation with sea water station " can build in wide wide shore line and bay everywhere, and the bright prospects of sustainable development are arranged.
Second point: the tide power station can only intermittent power generation, and " power generation with sea water station " use " artificial seawater space " and " storehouse Wai Shui " can accomplish round-the-clock long-term generating.
Thirdly: we design " splicing type horizontal hydraulic unit " voluntarily, have creatively realized the required very strong driving force of generating electricity.
More than 3 points, the just advance at " power generation with sea water station ", originality part.
3. realize round-the-clock generating
In order can uninterruptedly to generate electricity, we also participate storehouse Wai Shui (water in sea).Between first, second reservoir area, set up a current control Ba Qu (seeing Fig. 1,2) again.By the first reservoir area on one side be water control region into, on one side be the water outlet control region by the second reservoir area.Form five constituent elements (first reservoir area, water inlet control region, water wheels unit, water outlet control region, second reservoir area) like this.By controlling each gate group, the water inlet control region can allow the retaining of first reservoir area enter the water wheels unit or allow storehouse Wai Shui enter the water wheels unit.Equally, the water outlet control region can allow water turbine water outlet (sea) outside second reservoir area or storehouse sluice.Participating in of water outside the storehouse arranged, made " power generation with sea water station " obtain more energy, created the essential condition of round-the-clock long-term generating.
Three row's electric gate valve groups are housed on the water inlet control region dykes and dams, and wherein two row's electric gate valve groups (C gate group and G gate group) are regulated and control first reservoir area current water inlet turbines, current water inlet wheels outside another row's electric gate valve group (D gate group) regulation and control storehouse.Two row's electric gate valve groups also are housed on the water outlet control region dykes and dams, and wherein row's electric gate valve group (E gate group) regulation and control water turbine water outlet leaks into (sea) outside the storehouse, and another row's electric gate valve group (F gate group) regulation and control water turbine water outlet leaks into the second reservoir area.
4. about electric gate valve
Electric gate valve hole height needs about 3 meters approximately.
A, C, D, G gate group are installed in 2.5 meters positions of sea horizon, B, E, F gate be installed in 0 position of sea horizon.To determine the gate number of each gate group to satisfy the working water flow.
5. about water turbine
Because the seawater fluctuation has only several meters water-head distance, be seldom with the conventional resulting strength of water wheels unit, can not satisfy the generating requirement.For this reason, we adopt " splicing pattern horizontal water turbine group " (see figure 3).Method is that the width of blade of water turbine is increased H doubly, allows power also increase the H position, and several water turbine concentric splicings, is combined into the horizontal hydraulic unit.The water wheels unit will obtain slow and strong rotating speed, through variable transmission mechanism, produce and will satisfy required rotating speed of generator and strength, make generator for electricity generation.
Water turbine central shaft position is in sea horizon 2.5 meter sides.
6, about safety in production
If big flood takes place in land, open all gates, make the reservoir area become sea (the same water level in reservoir area and sea), allow flood leak into the reservoir area through empty door, guarantee the flood fighting water drainage.
If typhoon arrives, suspend and produce, the staff recalls land, guarantees personal safety.
If dykes and dams suffer war or accidental destruction, the water of reservoir area only can leak into the sea, can not produce the land lives and properties to threaten.The energy at " power generation with sea water station " is safe thus.

The 3rd period (see figure 6): begin ebb tide after seawater increases to again, when dropping down onto 3 meters of sea horizons (at this moment, first reservoir water level=sea horizon is more than 5 meters, 1.5 meters of second reservoir water level ≈ sea horizons), open C gate group, close and close D gate group, allow the retaining of first reservoir area come out from C gate group, behind the impulse water turbine, still let out to the second reservoir area from F gate group.
The 4th period (see figure 7): when seawater drops down onto (at this moment, 4.5 meters of first reservoir water level ≈ sea horizons, 2 meters of second reservoir water level ≈) when being equal to or less than the second reservoir water level, open B, E gate group, the water level of second reservoir area is together landed in company with seawater.The current of impulse water turbine leak into the sea from E, F, B gate group.
The 5th period (see figure 8): seawater continues to fall, and when dropping down onto lowest water level (at this moment, 4 meters of first reservoir water level ≈ sea horizons, 0 of second reservoir water level=sea horizon), closes and closes B, F gate group, makes the second reservoir water level be in 0 of sea horizon again.The current of impulse water turbine continue to leak into the sea from E gate group.
The 6th period (see figure 9): begin tidal bulge again after the seawater tide is flat, when rising to 2 meters of sea horizons (at this moment, 3.5 meters of first reservoir water level ≈ sea horizons, 0.1 meter of second reservoir water level ≈ sea horizon), open F gate group, close and close E gate group, allow the retaining of first reservoir area come out from C gate group, behind the impulse water turbine, change from F gate group and sluice to the second reservoir area.
When seawater rises when being equal to or higher than the first reservoir water level, open A, D gate group.This end cycle is again since first period.
Like this: according to the situation of seawater fluctuation, at first operate each gate group repeatedly and regulate and control current trends, keep the water-head distance, allow water impact water wheels unit, produce electric energy incessantly.
