Verify the efficiency of this tidal power generation system below by calculation of parameter.
Sea morning and evening tides drop is different all over the world, maximum more than 18 meters, and little 3 ~ 5 meters, in Chinese east coast, maximum drop is more than 8 meters. The selected drop of this example is 7 meters, and electricity generation system is placed on sea all right with bay place. Selecting the area of 1 square kilometre at a bay place, is also that 1000 meters of x1000 rice foursquare made above one 25 meters of high casings. Casing four side seals, bottom falls to being in most on a horizontal line after with sea ebb tide. The casing side that faces the sea is separated into three parts, long 400 meters of a middle part, and its sealed bottom, lower part forms holds water tank, holds two ends in water tank and respectively erects 3 meters of thick isolation dam bodys, and its internal orifice has grown up to 394 meters. The bottom that holds water tank lateral wall also erects 3 meters of thick dam bodys, 297 meters of path lengths in every part, its bottom-open. The height that holds water tank and low tank is 7 meters, i.e. the drop of sea the tide is flowing and ebbing is seawater activity interval simultaneously; Seawater activity interval height is divided by seven deciles, and each 1/7th is 1 meter high. Water head tank is located at 21 meters of of casing mid portion. From top to bottom, first 1/7th place of seawater activity interval is made as the fixing tank of the first low level, respectively opens a gate, i.e. water intaking valve at low tank two ends with corresponding junction; Be made as the second low tank, third and fourth 1/7th place at the 1/2nd place as interval, electrical generation water whereabouts, its height is 2 meters. Down three 1st/7th again, hold between pool (appearance water tank), collect the water storage of generating electricity specially.
In two side box bodies, respectively make a set of unsteady tank, dark 2 meters of unsteady tank, long 294 meters, width is 1000 meters, make one too huge, can make 3 ~ 4, remove gap, wide is 980 meters, and 980 meters * 2 meters, the tank capacity 294* rice of floating is so 576240 cubic metres, the cursory high 3 meters of tank of floating, long 296.9 meters, wide 980 meters, cursory volume is 296.9 meters * 980 meters * 3 meters=872886 cubic metres, and its 2.2 meters of high volumes are 640116 cubic metres. Top cell body, bottom is cursory, and centre is connected by many bracing frames 14 meters high. Cursory surrounding outer wall is installed many cover sinking driving mechanisms, i.e. pinion and rack with casing surrounding inwall. Be positioned on long 3 meters of tooth bar on cursory, long 19 meters of the tooth bar on casing. At this moment the eminence position of unsteady tank in floating, treats that seawater has fallen the time of tide, and the tank that floats drop to seawater by the driving mechanisms control of sinking and falls to locating most the water surface, and this section falls need not give power, naturally declines. Fall into after water when cursory, sinking driving mechanism forces cursory one-tenth dive to the 12 meters of depths, below, place that fall most. Select 1 meter of 1000 diameter, the pipe of long 3 meters be uniformly distributed in cursory in as upper and lower aquaporin (penetrating hole), its shared volume is 0.5 meter * 0.5 meter * 3.14*1000*3=2355 cubic meter, its 2.2 meters of high volume is 1727 cubic metres. Cursory 2.2 meters of high volumes are 640116 cubic metres, and cursory 2.2 meters of high actual volumes are 640116 cubic metres-1727 cubic metres=6383893 cubic metres, have more 638389 cubic metres-576240 cubic metres=62149 cubic metres than the water in cell body above. Under such gap, the gross weight of tank of floating is controlled in 30,000 tons, is enough to float to eminence, and while floating, cursory bottom is in the seawater 2.2 meters of deep-seateds in place that rise most and puts, and is namely 2.2 meters in the cursory draft in place that rises most. Cursory 0.8 meter of the water surface that exposes of 3 meters high, bracing frame is high 14 meters, and to rise the hoisting depth of assembly be 14.8 meters to water extraction so, and this water that has highly determined that both sides promote in two unsteady tanks that hoist can all discharge to water head tank. The pipe area occupied that 1000 diameters are 1 meter is 0.5 meter * 0.5 meter * 3.14*1000=785 square metre, and so large delivery port, is enough to ensure that water extraction rises assembly and rises smoothly, reduces resistance when dive. Four cursory angles are all installed four groups and are stablized scroll wheel, and two four jiaos of side box bodies are installed stable orbit, guarantee that water extraction rises the stability that assembly moves up and down. From multiple technologies aspect, the operation principle that water extraction rises assembly is feasible.
Sea is 12 hours 24 minutes between a fluctuation time of tide, and wherein duration of tide is 4 hours, while locating, is slack tide to rising most, and the slack tide time is 2 hours 12 minutes. Ebb tide after slack tide, fall time is 4 hours, slack tide 2 hours 12 minutes again when falling to locating most. This case sea drop is 7 meters, so often rise 1 meter or often fall 1 meter consuming time 34 minutes.
When sea, flood tide starts, and seawater up gushes and rises, after 4 hours, and middle low tank, the unsteady tank in both sides has all been filled water. At this moment the low level lockable mechanism release at two cursory places, two unsteady tanks are served eminence two groove water under buoyancy, and its aspect ratio water head tank has exceeded 0.8 meter. Two whiles of floating discharge water to water head tank and start, and water head tank opens whereabouts pipeline generating, and the time was controlled within 744 minutes, and its flow for generating is 60 seconds=25.8 tons of 744 points of ÷ of 576240 ton of * 2 ÷, and its drop is 18 meters. The closure when intake gate of the first low tank starts ebb tide in sea, starts generating from water inlet and adds that the slack tide time, within totally 166 minutes, after gate closure, the full water time was 578 minutes all in generating. It can be 60 seconds=11.13 tons of 578 points of ÷ of 386120 tons of ÷ for the flow of generating, and drop is 3 meters, and it 166 minutes is also that this flow is in generating. The second low tank takies generating dutation 234 minutes from starting water inlet generating altogether to closing gate, the full water time after the second low tank closing gate is 510 minutes so, it can be 60 seconds=12.6 tons of 510 minutes ÷ of 386120 tons of ÷ for flow of generating, and its drop is 2 meters. When sea ebb tide to seawater activity interval from top to bottom number the 4th 1/7th place time, holding the drainage gate of water tank opens, hold the electrical generation water of water tank collection and return sea with ebb, its water discharge time is gone through nearly 4 hours, is enough to the water of super its capacity of collecting all to return sea. Sea starts at the incoming tide again, and drainage gate is controlled closed by drainage gate switch (digital control system). When seawater rise to seawater activity interval from top to bottom number second 1/7th place time, the sluice that adds of the second low tank and unsteady tank is opened by digital control system. When seawater rises to seawater activity interval from top to bottom when first 1/7th place of number, the intake gate of the first low tank is opened. When seawater stops at the incoming tide, the low level lockable mechanism release tank that floats, the sluice that adds of the tank that simultaneously floats is closed. In the time that two unsteady tanks rise to specified altitude assignment, add sluice and open and can be water head tank and add water. Add water to before ebb high-order lockable mechanism locking. When water head tank and low tank have water, the switch in its lower downpipe road (can economize) is opened and just can be carried out generating work.
