Abstract
A flowing water power station directly acquires potential energy from the river water to generate electricity. The place having large river hypsography is chosen and a power station on the side of the riverbed is built. The power station is composed of a water intake part, a turbine running field part, a power transfer part, a generator producing field part and a water output part. The river flowing water is introduced into the turbine running field and then return to the downstream river after driving the turbine unit run. The generator can obtain enough power (needed rotate speed and power) to generate electricity for whole day by applying a waterwheel splicing type turbine with the flowing water push force as power and a method for acquiring flowing potential energy time after time, and operating a drive mechanism and a speed regulator.
Description
One, technical field
The present invention relates to new theory in hydraulic and electric engineering application in engineering, the technical field of in small stream river, mountain area water, generating electricity.
Two, background technique
Water resources is valuable renewable resources, and people early have recognized that and utilize it.For example: waterwheel (potential energy with small stream river water becomes kinetic energy) be hill farmer it be used for irrigating, the tool of production of works such as husk rice, papermaking and abrasive dust.The progress in epoch makes it to die down.Now, also can find its trace in the Lijiang City, Yunnan Province, the scenic spot Lijing grinds greatly in the small stream river of ancient city mouth and is founding two waterwheels, and people can have a taste of this ancient civilization elegance that has disappeared; An ancient village in Nanxijiang river mountain area, upstream, the Oujiang River tributary, Zhejiang Province, legend the villager here envies the joys of life such as Plain people swimming in river pool, dragon-boat racing, and everybody starts to make Dou Men in the small stream river on own home doorway, builds the reservoir area (this perhaps be the reservoir of earliest period) in history.People breed fish in the reservoir area, row the boat, swim, with storehouse water drought control irrigation.This ancient village is exactly present Dou Men village, Dou Men township, Yongjia county.The effect of steep door is retaining and the cloudburst usefulness of drainning off floodwaters season.At that time, be a marvelous invention, the villager proudly is decided to be the Dou Men village to village's name, always along so far.
Today, water conservancy has become one of development key pillars of the national economy.Flood fighting, take precautions against drought, irrigation, water transfer, generating, bank protection, dredge boat, culture---it is outstanding to wait multiple function to contribute for the people benefit.Wherein hydroelectric project is an important component part in the water conservancy.
Hydroelectric power is the process that potential energy changes electric energy into.Build reservoir, the potential energy impulse water turbine generation running strength with the reservoir area retaining drives generator and produces electric energy, and this is the generation mode in waterpower power station.It has science, practicability.But there is an insurmountable problem: build the reservoir area and need take a large amount of soils, the storehouse water logging there has not been village and mountain forest, cause soil erosion, destroyed ecotope, and bury potential safety hazard, in a single day the reservoir area dam suffers from unexpected dangerous situation, will cause immeasurable harm to downstream, the reservoir area people's life, property.For this reason, make the hydraulic and electric engineering cause bring can not sustainable fast development consequence.
In addition, the scenic spot that many beautiful scenerys are often arranged in the abundant place of water resources is as national scenic spot Nanxijiang river, very famous Hu Tiao Gorge, first gulf, the Changjiang river ... Deng, if build the reservoir area in these places, mean that they will disappear forever, the descendant is decided to be the wrong move of today and annoyance.
For this reason, there is not above-mentioned problem fully in " power station of running water " that we propose, and its birth will be the another approach that the Hydropower Development engineering has realistic meaning.
Three, summary of the invention
In the mountain area, landform changes complicated, another mountain, a mountain, and one is curved another curved.But the water of intermountain is always toward lower stream, and the mountain is not changeed water and changeed, and changess and soil erosion through the time of not knowing what years, among many mountains, formed the small stream river of a having many bends or curves only stone and stone under the foot of the hill.Because landform is gap up and down, cause in the riverbed flowing water from top to bottom, the time slow when anxious, day and night do not stop to head direct among the rivers of downstream.
The current of Pentium are dived with the huge energy---potential energy, and the gap up and down of landform and water flow what the size of energy depends on.In case current arrive in the static water surface in downstream, flowing slowly stops the potential energy Lock-out.
Because the geologic structure difference, the location that has in the small stream river is the lithosphere structure, and silt rock layer structure is originally in the location that has.Through long-term weathering and the strong motion of urgency that Freshets roar down from the mountains many times, lithosphere is still settled upright motionless.And the silt in the silt rock layer is impacted loss, and the Ling Jiao of stone is ground off by roll, causes the riverbed step-down, only remaining egg rock layer only different, not of uniform size.And be lower than lithosphere, and form the physical features gap that often there is certain altitude in the two handing-over location, make the flowing water of process produce same water-head distance highly.
In addition, the two sides in small stream river, the two sides, location that have all are level land (silt rock layer structures), Yi Bian perhaps be the level land, Yi Bian be rock.The two sides, location that have all are rocks.As a same reason, a large amount of silt is taken away in the strong motion of the urgency that Freshets roar down from the mountains, makes that to be in two sides (a perhaps bank) be that the riverbed in location, level land is arbitrarily widened.And two sides all are the locations of rock, and the distance between the rock of two sides is exactly the width in small stream river, and the dynamics that Freshets roar down from the mountains is had no way out to it, can not change the width in riverbed.If distance is very near between the rock of two sides, the small stream river is also just narrow so.It is extensively wide to have formed the riverbed, location that the small stream river has like this, and the riverbed, location that has is narrow.Flowing water is slow slowly during through wide wide riverbed, and is anxious soon during through narrow riverbed.
Our " power station of running water " is exactly to utilize valuable renewable water resources, directly obtains potential energy in free-pouring flowing water and produces electric energy.
" power station of running water " will be built that the landform gap is big, streamflow is many in, not do the small stream korneforos of not freezing throughout the year.Select the big location (lithosphere and egg stone layer jointing place that the certain altitude gap is arranged) of physical features height gap in the riverbed.At next door, small stream river excavation earth, build power station and water-drawing channel.Water-drawing channel changes its course the current of small stream korneforos, allows flowing water enter " power station of running water ", promotes the water turbine running and the drive generator for electricity generation.Current finish after the mission through water outlet again stream return among the small stream river, downstream.
Our this practice, inevitablely be queried at once and negate: do " power station of running water " only utilize small stream river water can make generator for electricity generation? even if can generate electricity, what can be sent out? this " has a fantastic idea " only not!
Yes, perhaps can be to have a fantastic idea, but we have distinguished understanding:
As everybody knows, make generator produce electric energy, must give its strength---fast turn-around power.Hydroelectric power provides running strength by water turbine, and what the running strength of water turbine come from so? be to rely on the water flow (weight of water and water velocity) that contains potential energy that water turbine is done work to obtain.Perhaps say: the water flow (kg/s) that certain gravity (kg) is arranged with time per unit (s) lining is the impulse water turbine blade continuously, and makes water turbine produce running strength.What of the water yield can be used weight (T or kg) or volume (m
3) calculate, so the unit of flow also can use m
3/ S represents.
How to accomplish in time per unit (s) lining, allow much more so water flow (m
3/ S) to acting (impact) on the limited blade of area? can only take " high-handed policy, compulsive means ", use advantage can force water flow that the turbine blade intense impact is obtained fast turn-around.So till the present, all hydroelectric powers all are will build dam to make the reservoir area.Purpose is with dam block resistance current, allows the reservoir area retaining, being in the storehouse water that weak tendency can small stream river water becomes surging energy (high head).
" power station of running water " just utilizes the flowing water that is in the weak tendency energy to generate electricity, can turn one's dream into reality? clear for answering, talk about from the formula of power earlier:
The formula of power (claiming " exerting oneself " on the specialty): N=9.81nHQ (KW).
In the formula: the 9.81st, gravity accleration, n are efficient, and H is head (m), and Q is flow (m
3/ S).From formula as can be seen: the 9.81st, constant, unalterable.Manage to raise the efficiency n (improving equipment performances such as water turbine, generator, speed regulator), but n was less than for 1 (having running frictional resistance, own wt etc. because of equipment) forever.Thus: head H and flow Q are the principal elements of decision watt level.In other words: head and flow have determined the generating capacity in power station, and reservoir area average of the whole year head and annual water retention capacity (storage capacity) have determined the annual generated energy in this power station.
Suppose to build water power plant, a reservoir area at the A in a small stream river (as Fig. 1) point.125 meters of dam height, 120 meters of safe-guard lines.In the reservoir area during 120 meters of maximum retaining height, flood the G place of scope to the small stream korneforos.Use counterattack type inclined flow turbine, the type water turbine accommodation: 40-120 rice head.Because water turbine can not produce when head is lower than 40 meters, so head actual using scope in reservoir area is between the 120-40 rice.In addition,, the branch of rainy season and arid season there is every year, can not keeps 120 meters the whole year by reservoir water level, suppose that the average of the whole year head is 80 meters owing to the difference in season.
Now, if what build in this small stream river is " power station of running water ", A point same in Fig. 1 is to location between the G point of reservoir area scope that the water power plant is flooded, build several " power station of running water ", how will situation (the two is heterogeneity for water power plant, reservoir area and power station of running water, can only be relatively) be?
Suppose that at this point A, B, C, D, E, the F point of section are built 6 " power station of running water ".Known A point is to G point landform 120 meters of gaps up and down, and every power station average height difference is 120 ÷ 6=20 (m).Because physical features is natural, so the running water level difference in small stream river can not change, the water-head altogether (head) of 6 " power station of running water " is 120 meters forever.It is greater than 80 meters of the average water heads in water power plant, reservoir area.
Build the water power plant, reservoir area that A is ordered in, its annual water retention capacity is that (the volume of flood that does not comprise extra torrential rain and taken place is measured in the annual streams of order through A in this small stream river, because extraodinary flood is artificial irresistible strength, consider the bearing capacity and area, the downstream people life property safety of reservoir area construction cost, dam when design is built in water power plant, every institute reservoir area, all take flood-relief measure).Equally, build " power station of running water " that A is ordered in, the water flow of its annual gained also is the annual streams amount of ordering through A in this small stream river (when extraodinary flood broke out, flood was from the former road venting in small stream river).Yet " power station of running water " that B, C, D, E, F are ordered also used the flowing water in this small stream river simultaneously, and the water flow utilization rate of 6 " power station of running water " gained is several times of reservoir area water power plant retaining gained water yield utilization rate.
Thus: in a same small stream river, in the location of a same scope, several " power station of running water " can make full use of precious water resource, and gross head, water flow utilization rate all surpass the water power plant, reservoir area, so generated energy also will be above water power plant, reservoir area (wouldn't comprise efficient n).The formula that this meets power meets law of conservation of energy.
Since " power station of running water " be in weak tendency can flowing water in move, it is simple in structure, construction period is fast, and the construction cost of 6 " power station of running water " is well below the input cost (want to stand the dam construction cost of high hydraulic pressure, the flood-relief measure of controlling flood cost, flood the cost of soil cost, immigrant's cost and ecological failure etc.) in water power plant, a reservoir area.So " power station of running water " is not to talk about stratagems on paper, and the feasibility of successful implementation is arranged.
So far, can draw such conclusion:
1. the storehouse water in water power plant, reservoir area is the surging energy high density energy, and it is made, and the size of head is changing; The flowing water of " power station of running water " is the weak tendency energy low density energy, and it is natural eternal, and the size of head changes never.
2. what advantage can make is impact force; Weak tendency can be Driving force.
3. the disposable performance of surging energy potentiality; Weak tendency can potentiality can be obtained step by step.
4. " power station of running water " maximum " shortcoming " is: owing to can not store the water yield, generated energy changes with the flowing water size.This but " shortcoming " can overcome fully, because peak is all arranged in the electrical network.Great advantage is: be exactly the shortcoming that does not exist the water power plant, reservoir area to overcome.If people admit it, understand it, pay attention to it, so, " power station of running water " must also can contribute for the hydraulic and electric engineering career development as the water power plant, reservoir area.
Four, description of drawings
Below in conjunction with embodiment and accompanying drawing thereof " power station of running water " remake description.
Fig. 1 is a small stream river physical features schematic representation, among the figure: 1. water power plant, reservoir area dam; 2. storehouse water; 3. small stream river physical features; A, B, C, D, E, F select and are small stream river lithosphere and location, egg stone jointing place.Each location self has the certain altitude gap, if power station of running water is built this location in, just can obtain the advantage of certain altitude gap in the production site in power station.
Suppose that the A point is built water power plant, a reservoir area in the drawings, storehouse water flood when being filled with water the phase to scope to the G point.If build 6 " power station of running water ", because of physical features height gap is natural, so the head of each " power station of running water " is fixed at A point to G point.But water velocity is owing to reasons such as the length of flow process distance and the bending of small stream river produce water resistance, and image current equally can more or less be weakened by the influence of lead (specific resistance, length, cross section) resistance to some extent.
Fig. 2 is " power station of running water " example structure figure, among the figure: ← expression flowing water trend;
Current trend when the expression flood takes place: 1. small stream river; 2. hurdle water weir; 3. water-drawing channel; 4. water intake; 5. gate; 6. passage; 7. water turbine flowing water channel; 8. the current channel is every beam; 9. Waterwheel-type splicing type water wheels unit; 10. speed booster driving mechanism; 11. Generators; 12. water outlet; 13. water outlet channel.Project subject (blocking water weir, water-drawing channel, water turbine flowing water channel and water outlet channel etc.) is to build up with reinforced concrete construction.
" power station of running water " graded by water inlet portion, hydraulic turbine operation place part, power transfer part, generator production site part and outlet part and constitutes.
1. water inlet portion: form by blocking water weir and water-drawing channel, its effect is changed its course whole current in small stream river (being included in the rainy current that season, the small stream river was filled with water period) and is flowed to the power station water inlet.Because situation is different, after current change its course, three kinds of situations can occur on the spot: 1. stop on the lithosphere of small stream river, this explanation is drawn and is connected into merit, but this situation is few.2. local flowing water in addition on the lithosphere so, is increased with reinforced concrete construction in this local area, makes current all introduce the power station.3. still have a lot of flowing water from small stream river lithosphere process, so, add on lithosphere and build one and block the water weir, the height on dam can accomplish to stop that the whole current changed courses in small stream river of the phase of being filled with water flow into the power station and get final product.This dam is pure to be the usefulness of diversion, has only several meters high at most, is not that the dam in water power plant, reservoir area is used for retaining.When flood took place, flood was still from former road direction downstream, small stream river venting.
2. hydraulic turbine operation place part: form every beam, Waterwheel-type splicing type water wheels unit and water outlet by water intake, gate, passage, water turbine flowing water channel, flowing water channel.
Water intake enters water turbine flowing water channel by flowing water.
Gate is used for the current in control flows water channel road.
Passage is the usefulness that supplies operator and crane to walk when installation, maintenance equipment.
Water turbine flowing water channel provides the usefulness of the required flowing water of water turbine running.According to the theory of " weak tendency energy potentiality can be obtained step by step ", the physical features gap advantage of utilizing power station production site self to exist is built up stepped to channel, and every step is all installed draining wheel unit.Flowing water flows to each water turbine flowing water channel from water-drawing channel, toward dirty, promotes the water turbine on each step along step one-level one-level step by step through water intake, gate, makes each step water wheels unit all obtain the strength that turns round simultaneously.
3. motivation transfer motion part: power-transmitting unit adopts the mechanical drive mode (chain-driven, band transmission, gear transmission) in the modern industry.Form by the drive sprocket that is contained in water wheels spindle end limit (or driving pulley), the chain (or endless belt) that is contained in the driven sprocket on Generators running spindle end limit and connects them.Its effect: 1. change running speed; 2. transmit running power.The rotation strength that water turbine is obtained that flowing water promotes and produce sends the running main shaft to.
Adopt the sort of kind of drive and transmission speed ratio, belong to design details, this paper is omitted.
4. generator production site part: Generators is not built in or not can be made up of running main shaft, some power generating equipments (generator, clutch, speed regulator, excitation system) and Control of Power Plant equipment etc. by the eminence that flood flooded.Equipment will be installed and be connected in accordance with regulations.Wherein the speed regulator effect is: the running speed of running main shaft is adjusted to and meets the required rotating speed of generator.The task of clutch is: the clutch that closes, and make generator participate in operation and produce, cut-off clutch makes generator stop to produce.
5. water part: flowing water comes out from water outlet after finishing mission, returns small stream korneforos, downstream again through the water outlet channel.
Fig. 3 is the structural representation of Waterwheel-type splicing type water turbine.Among the figure: ← expression flowing water trend; 4. water intake; 5. gate; 11. Generators; 12. water outlet; 14. base; 15. double-screw bolt; 16. hydraulic turbine main shaft; 17. coupling; 18. bearing; 19. base upper cover; 20. hydraulic turbine main shaft end side chain wheel; 21. runner support; 22. blade; 23. drive sprocket; 24. chain; 25. driven sprocket; 26. running main shaft.
How can " power station of running water " therefrom obtain potential and produce running strength in the face of the flowing water of the big flow in a small stream river, low water head? this is really most important, the most critical issue of success of decision " power station of running water ".Use the used various water turbine in water power plant, reservoir area not all right certainly, can only adopt special water turbine---the Waterwheel-type splicing type water turbine of innovation.
These water turbine characteristics: 1. as waterwheel, the rotary wheel of water turbine stent diameter is very big; 2. runner support (blade that comprises top loading) length is very long; 3. with coupling several water turbine are spliced into the water wheels unit of a coaxial line.4. water turbine can be in assembling of job site, power station or welding, to adapt to convenient transportation.
Suppose the small stream river at the flowing water sectional area of the phase of being filled with water through being measured as 15 square metres, if turbine blade drinking water height (flowing water channel height of water level) is 0.5 meter, the width of channel is 30 meters (15m so
2÷ 0.5m=30m).We build up 3 to flowing water channel branch, and every wide 10 meters, and at every flowing water channel blade being installed is 10 meters long water turbine, and with 2 coupling the water turbine on three flowing water channels is coupled together, and forming one is 30 meters long water wheels unit altogether.Like this, can be the whole works done (promotion) of the flowing water in small stream river " one does not leak " in water turbine.Perhaps say: successfully obtained the potential in the flowing water.
In addition, according to simple lever principle---two power (power and resistance) size of effect lever follows their arm of force to be inversely proportional to, its formula: power * power arm=resistance * resistance arm (is expressed as FL1=WL2 with algebraic expression, F represents power in the formula, L1 represents power arm, W represents resistance, and L2 represents resistance arm).Power arm is several times of resistance arm, and power is the part of resistance.It is long that water turbine radius (power arm L1) is made several rice, and as ancient waterwheel, (flowing water thrust F) overcomes big resistance with little power.
Take above-mentioned two kinds of methods, make water turbine produce slow and strong running strength through the promotion of flowing water, and the running strength of each step water wheels unit is merged together, through the transmission of power-transmitting unit and speed regulator, clutch, make generator obtain required rotating speed and strength and produce electric energy.
The water turbine master unit is made of metallic material, is made up of base, hydraulic turbine main shaft, spindle end limit key wheel, bearing, base upper cover, runner support, blade, chain, coupling and double-screw bolt etc.
Runner support, blade, bearing and end side chain wheel are installed on the hydraulic turbine main shaft.
The effect of bearing is rotated flexibly water turbine, and base upper cover and double-screw bolt load it on base.
Water turbine integral body is by base support, base be installed in the flowing water channel on beam.
Coupling is used for two splicings between the water turbine.When splicing was installed, each hydraulic turbine main shaft will accomplish that coaxial line connects, and can turn round flexibly.Integral body will be in same level.
Chain connects the end side chain wheel of water wheels units at different levels, water wheels units at different levels is connected be merged with the speed running.
Because the differences such as scale, electric motor power, water flow, water velocity and conditions of transportation of each " power station of running water ".So, should work out the issue implementation criteria, the water turbine of design different size uses and maintenance in the future for you to choose.
The technical parameter of formulating standard should comprise: the drinking water height of the length of the diameter of the structure of water turbine, bearing capacity, main shaft diameter, runner support and length, blade and width, blade ... Deng.
Five, embodiment
At first, carry out field study, measurement calculating.Because of the suit every concrete scheme of planning and designing " power station of running water " of ground:
1. the various factorss such as streamflow, flowing water speed and landform gap during being filled with water according to the small stream river are determined the electric motor power (total generated output) in power station.Change because of season is different for adapting to streamflow, need to install several generators and be used for the regulating and controlling generated energy.Every generator power=total generated output ÷ platform number.
2. the flowing water height of flowing water channel is determined by turbine blade drinking water height.The drinking water height of the flowing water height=turbine blade of channel.
3. the flowing water sectional area during being filled with water according to the small stream river and the requirement of flowing water channel water height decide the overall width of flowing water channel.The overall width of flowing water channel=small stream river water sectional area (m
2) the flowing water height (m) of ÷ current channel.
4. determine the bar number of flowing water channel according to the length of flowing water channel overall width and water turbine.The length of the bar number of flowing water channel=flowing water channel overall width ÷ water turbine.
5. a gate is installed in every flowing water channel front.
6. the height of step is greater than the drinking water height (height of water level of flowing water channel) of turbine blade.Because water turbine comes into operation, increased the flowing water resistance, water level raises naturally.If it is not all right that water level rises above rise, can higher level's water turbine running be exerted an influence, thus only be lower than rise, just can mutual noninterference.But step can not be too high, as long as the water level after putting into operation a little more than water turbine.Too high, the utilization of waste resource can reduce the progression of step.
7. physical features gap that self exists and the rise according to the place, power station determines step progression.The physical features gap ÷ rise in progression=place self.
When the power station formally produces,, regulate the control generated energy, carry out round-the-clock uninterrupted production according to the small stream river water yield:
1. during the small stream river is filled with water, open all gates, allow water turbine at different levels all participate in operation on every flowing water channel.Simultaneously, allow every generator also all participate in generating.During this, plant generator is in the optimum state.
2. working as small stream river water reduces to some extent, when influencing the drinking water height of turbine blade, shut gate from Generators flowing water channel front farthest, allow and be in every grade of water turbine (pulling down coupling) out of service on this channel, make other flowing water channel increase water level, guarantee that operating water wheels unit runs well.
When small stream river water weakens once more, take same manner (to shut the gate of adjacent channel front ...).
3. reduce water turbine and participated in operation, must influence the running strength of running main shaft.To increase and decrease generating board number through the manipulation of clutch according to the size of running strength, to guarantee what of power generating quality and definite generated energy.
