The structural requirements in above-mentioned ebb power station 2 etc. are similar substantially to the structural requirement etc. in above-mentioned flood tide power station, and in order to avoid giving unnecessary details: the different propositions in three places in now will ebb tide power station 2 and rising tide power station 1 are contrasted narration.
First difference: the weir wall of ebb both sides, gate hole, power station is provided with through flow hole 13, retaining flashboard 15 is arranged on the weir wall of through flow hole inboard, with so that at the incoming tide tidewater by through flow hole flow in the dam, at ebb tide with through flow hole sealing, flood tide that power generation system flows out to outside the dam by flexible to make water in the dam.And flood tide the sluice board 14 in power station is arranged on weir wall is outer, in order at the incoming tide with the through flow hole sealing, flood tide that power generation system flow in the dam by flexible to make tidewater, and the tidewater in the dam is released as soon as possible by through flow hole on the ebb the time.Therefore, two places are provided with the functions reversed that rises.
Second difference: the direction difference of the liquid inlet and outlet of turbine.The turbine liquid entering hole is in dam in the ebb power station 2, and liquid outlet is outside dam; Flood tide, and the power station is then opposite, and promptly the turbine liquid entering hole is that liquid outlet is in dam outside dam (direction of rising).This also is the difference of rising tide power station and ebb power station essence.
The 3rd difference: the set position of two columns 5 and buoyancy aid 6 is different.In the ebb power station 2, two columns 5 and buoyancy aid 6 are arranged in the wall of weir, and two columns 5 and the buoyancy aid 6 in aforesaid rising tide power station 1 are arranged on outside the dam.This be because, though buoyancy aid 6 can and seal the gate hole of corresponding height with tide come-up and the flexible gate sheet 32 of corresponding drive, 4 risings of turbo dynamo group at the incoming tide, but at ebb tide, buoyancy aid 6 can not be floated downward with the outer tidewater of dam, and can only with the tidewater of accumulating in the dam in the process of drives impeller machine running generating, float downward along with tidewater releases under the outer speed of the releasing influence of dam.
In addition, the through flow hole 13 on the two side weir walls of ebb 2 gate holes, power station is preferably two groups of height, along the short transverse upper and lower settings of weir wall.The damming lock door-plate 15 of downside is middle pressure flashboard, the pressure in the time of can bearing maximum tidal level; The retaining flashboard of upside is the low pressure flashboard, and gate sheet is lighter, and it is lower by force that flashboard bears the tidal level differential pressure, and the sensitivity of flashboard is higher.
In order to prevent to be subjected to billow that climatic impact produces, guarantee that the power station can be in smooth operation under the safety guarantee to the harmful effect that power plant safety may cause.Dam coastal waters one side in described rising tide power station and ebb power station is suitable at interval being provided with wave resistance embankment 10, the wave resistance embankment is built the outermost of tidal power station in, its length should surpass the length of tidal power station, and it moves back and the normal operation of power station dykes and dams outside facility is exceeded with smooth and easy the gushing that does not influence tidewater apart from the distance of tidal power station.The height of wave resistance embankment should a little more than or be equivalent to the height of tidal power station, having needs, and be extended to deepwater wharf to it so long, tidal power station is built in the inboard of deepwater wharf.
Details are as follows to the working procedure of tidal power station of the present invention and principle below.
Beginning that flood tide, the tide face rises to buoyancy aid 6 bottoms that are arranged on outside the rising tide power station, at this moment, because the quality of buoyancy aid 6 self, reach the quality of the flexible power generation system that links together by conduction hawser 7 and the resistance to motion of other conducting piece (pulley, hawser) itself, buoyancy aid 6 can not be done the come-up motion with tide immediately.Be installed on simultaneously under the natural force of sluice board 14 tidal load outside the weir on the 1 outer side weir wall of rising tide power station, with more and more tighter being closed of through flow hole in rising tide power station, rising tide is in the vacant state that tidewater can not flow into naturally in the power station 1 fully.Simultaneously, situation in the ebb power station 2 is just the opposite with the situation in the rising tide power station 1, because the retaining flashboard 15 in ebb power station 2 is contained on the inwall of cofferdam, therefore along with tidal level rise to, tidewater can be pushed the retaining flashboard 15 on the inwall of ebb cofferdam, power station very soon open, and tidewater pours in the embankment in ebb power station thereupon.Since be located at that flood tide power station 1 outer flood tide that buoyancy aid can not float immediately is identical, pour in the tidewater in the ebb power station 2, can not hold up the buoyancy aid 6 that is arranged in the ebb power station equally immediately, drive the flexible power generation system of ebb and do to float and move.
Continuous rise along with tidal level, the liquid entering hole that will be arranged on the turbo dynamo group 4 on the flexible gate of rising tide power station multilayer when damp face floods fully into Chao Mianxia, when the enough drives impeller machines of tidal level pressure energy drive generator operation, buoyancy aid 6 reaches the summation that overcomes every resistance, and the impeller generator set is with the ability (this is the main basis of design buoyancy aid buoyancy) of tide come-up.At this moment, buoyancy aid 6 begins to float continuously with tide, and drives the lock hole of flexible rising tide power generation system with tide come-up and sealing corresponding height by conduction hawser 7.Start the beginning of running along with flexible rising tide power generation system, the stream flashboard that holds by rising tide power station embankment and through-flow lock hole, both sides intercepts in the tidewater in the embankment outside, rising tide power station, under the driving of tidal level difference power inside and outside the dike, be forced to promote the turbine rotation, and inject in originally vacant rising tide power station 1 embankment by the rotation stream of turbine.This tidewater rotates the process that enters the embankment inboard by promoting turbine, promptly is the process of a tidewater acting, and the process of energy is extracted in the power station that is to say that flood tide from tidewater.
Continuous rise along with tidewater, buoyancy aid 6 in two power stations is done envelope lock ascending motion with damp impeller generator set 4 and the flexible gate sheet 32 of multilayer along the gate frame by conduction hawser 7, when on when moving highly the limiting altitude that surpasses the superiors' gate sheet, be located at the then gate sheet of the lower floor of band and its socket rising automatically of buckle of the superiors gate sheet inboard, follow this principle, rising progressively successively stops to flood tide.In the whole process of rising progressively with tide, the turbo dynamo group in the flexible rising tide power generation system remains at running continuous process of extracting electric energy from tidewater while rising progressively.At this moment, because the tidewater water surface inside and outside the dam maintains an equal level substantially mutually in this time period, the turbo dynamo group in the therefore flexible rising tide power generation system is failure to actuate.
Stop usually for some time, being called as the damp flat phase therebetween from flood tide to ebb.In this time, though the turbo dynamo group in the flexible power generation system of buoyancy aid 6 and rising tide has stopped vertical motion, the motion of turbo dynamo group 4 is still continuing.On the one hand, turbo dynamo group in the rising tide power station is because of in the rising tide phase, the tidewater that leaks in the rising tide power station by the turbine running also reaches the equal stage of horizontal plane that is filled to the outer tidewater of dam far away, because of drawing under the driving of tidal level difference power inside and outside the dam, the turbo dynamo group is remaining in operation, and continues to extract from tidewater energy; On the other hand, place, ebb power station, though be arranged at holding the stream flashboard and can not stopping pouring in of the outer tidewater of dam fully of ebb inboard, power station, but it is because the relation of sole mass, still stopped pouring in of part tidewater, cause the micro-difference of the inside and outside tidal level of dam, at this moment, be arranged on higher the holding of gate hole two upper lateral part through flow holes, 13 inboard sensitivity and flow flashboard 15, utilizing this section period to finely tune, dwindle the inside and outside gap of dam as far as possible so that can retain more tidewater, for the ebb generator set on the ebb the running in the phase more tidal level energy is provided.
As time goes on, the ebb beginning, the situation in two power stations begins change.
In the rising tide power station, when the tidal level outside the dam begins to do descending motion, turbo dynamo group 4 stall immediately, this be because, in the ebb phase, have only after natural tidal level is lower than the tidal level that leaks in the rising tide power station outside the rising tide power station, the tidal level pressure in the dam can from inside to outside be pushed the sluice board that is loaded on the outer wall of rising tide power station automatically open, and the tidewater that leaks in the rising tide power station is let out Gui Jianghai as early as possible.Turbo dynamo group 4 and buoyancy aid 6 are also along with natural tide reduces as far as possible.Wait for the arrival of next rising tide phase quietly.Circulation repeats the movement process of phase that rises, ebbs tide, and alternately extracts electric energy from natural morning and evening tides continuously from this movement process.
The ebb beginning, decline along with tidal level outside the cofferdam, be installed on holding on 2 dam both sides through flow hole 13 inwalls of ebb power station and flow flashboard 15, under the situation that inside and outside tidal level begins to change, tidal level power in the dam adds the quality of holding stream flashboard 15 self, beginning is sealed through flow hole 13 in dam, stop the tidewater that pours in the dam to flow out by through flow hole 13.And pressure along with the outer tidal level difference generation of dam, with more and more tighter being closed in influent stream gate hole on 2 dams of ebb power station, it is isolated fully that phase that makes that flood tide pours in the outer natural tidewater of tidewater and dam in the ebb power station 2, can not return Jiang Hai and be hoarded in the power station 2 of ebbing tide with the tidewater spontaneous regression.Tidal level in the tidal level outside the ebb power station 2 is lower than ebb power station 2, and when the tidal level power in the cofferdam can drive the turbo dynamo group running of flexible ebb power generation system, hoarded the tidewater in ebb power station 2, just have an opportunity to let out Gui Jianghai from the turbine liquid outlet by after being loaded on the turbine liquid entering hole drives impeller machine acting on the flexible gate of ebb power station multilayer.Form turbo dynamo group 4 and from ebb tidewater, extract the pattern of electric energy.Along with the tidewater that brings of continuous running of ebb generator set leaks, the tidal level of hoarding in the ebb power station descends thereupon.The related buoyancy aid 6 that is arranged in the ebb power station of the decline of tidal level begins to descend in the dam, the flexible ebb power generation system that the decline of buoyancy aid 6 causes conducting hawser 7 the other ends in the dam also descends thereupon, and manage the turbine liquid entering hole all the time at subsurface relative position, running is extracted electric energy from let out damp process continuously, flood tide that the cycle arrives until next, and ebb power station 2 inside and outside tidal level differences stop (volume that releases tidewater by turbine liquid in-out mouth during this is the foundation of calculation Design ebb embankment volume) when being not enough to drive the running of ebb generator set.Along with the rise arrival of ebb phase of the next one, ebb power station 2 and and the circulation of turbo dynamo group repeat the running program of the ebb phase of rising, alternately from natural morning and evening tides, extract electric energy endlessly.
In sum, tidal power station is under the protection of wave resistance embankment, obtain in safety under the situation of reliable guarantee, the natural morning and evening tides that the periodic cycle of utilizing earth rotation movement to form the produces process of moving back that rises, from wherein extracting electric energy, it has and the same needing no outside energy in general dam power station, can not produce dysgenic advantage to atmosphere and environment, has more the incomparable with it energy source in dam power station and does not take the valuable effectively advantage of land resources.Different with general dam power station is that morning and evening tides is subjected to the degree of natural environment influence littler than general dam power station.Tidal power station is built easy, and it is few to put forward money, and income is remote, does not take effective land resources, can yet be regarded as to obtain a kind of most economical, easy, the reliable and secure method of clean energy resource.
