connected between dam body wall 1, such as lower body part corresponding positions install sliding rail, frame body pulls each frame body point of cable wire 11 Trouble sets a sliding block on end, and sliding block is placed in inside corresponding sliding rail, and when floating drum drives water wheel frame to float, dam body is non-rising；Often It is hinged with 1 water wheels support frame 14 on a 12 top surface of water wheels support frame, a water is fixed on each water wheels support frame 14 Wheel 15, successively lengthens, and edge along the water wheels 15 of water (flow) direction from top to bottom and the distance between the water outlet that two dam body walls 1 are formed 15 radius of water wheels of water (flow) direction from top to bottom is sequentially increased.Water wheels support frame 14 can be promoted by lifting device, lifting dress Set to be one of mechanical lifting gear, hydraulic lift or Motorized lift device, in the present embodiment, lifting device machine Tool lifting device, i.e. lifting device are the pulley being fixed by the bracket on upper beam and the ratchet with crank, are connected by cord Water wheels support frame 14, pulley and crank, to realize the purpose of lifting water wheels 15；When the failure of water wheels 15 needs repairing, lead to It crosses lifting device and water wheels support frame 14 is opened into promotion upwards, water wheels 15 leave the water surface therewith, and water wheels 15 just stopped after being discharged Rotation, then the connection of universal joint 202 Yu wheel shaft is disconnected, it repairs so safer；It repairs in this way, the personnel of avoiding are lauched Maintenance is caused danger, and for relatively setting maintenance sluice, safety in utilization is higher.15 both ends of water wheels pass through bearing block and water wheels branch respectively Support frame 14 is fixedly connected, the bottom plate 16 of J-shaped is fixed in the frame body 10 below every layer of water wheels 15, positioned at water wheels 15 into The bottom plate 16 of water side be it is horizontally disposed, be equipped with a pair of of vertical plate 17 vertically in 10 inside two sides of frame body, bottom plate 16 is and vertical plate 17 are fixedly connected, and are successively arranged protective net 18 and gate-type sluice 19 between two vertical plates 17 of each piece of water inlet of bottom plate 16 side, The water inlet of gate-type sluice 19 and layer water wheels 15 where it is contour wide, after gate-type sluice 19 is closed, sheaf space closing not into Water.The space of relative closure is formed between bottom plate 16 and vertical plate 17, effect is first is that the oblique water flow for carrying out ponding convergence is parallel Ground flows through and water wheels 15 is pushed to rotate, and improves generating efficiency, second is that fixing the flow into this layer of water wheels, makes the river water to go up A upper sheaf space is flowed into, the thrust of this layer of water wheels 15 will not be increased due to eagre；Two vertical plates of the water inlet of water wheels 15 side Protective net 18 is equipped between 17,18 one side of protective net can protect water wheels 15, avoid in water flow branch or biggish sundries into Enter and cause the damage of water wheels 15, on the other hand can prevent the human or animal to fall into the water from entering in water wheels 15 with water flow, quilt The water wheels 15 of rotation injure.A gate-type sluice 19 is equipped between two vertical plates 17 of the water inlet of water wheels 15 side；Gate-type sluice 19 wraps Shaft 191 and flashboard 192 are included, shaft 191 is fixed on the side wall of a cant board 17 vertically, and 192 side of flashboard and shaft 191 are cut with scissors It connects；If when the river water underfill sheaf space, the thrust of this layer of water flow is not achieved this layer of water wheels 15 and rotates required thrust, power generation Machine 204 cannot work normally, and sluice 19 is closed at this time, and water level temporarily goes up, until water level go up to can be full of the sheaf space when, Sluice 19 is opened, water flow, which enters in the sheaf space, pushes water wheels 15 to rotate, and generator 204 can work normally；In addition, if same layer water Stream thrust is excessive, and 15 revolving speed of water wheels positioned at 19 rear of gate-type sluice is too fast, and 204 actual power of generator is greater than rated power When, 19 aperture of gate-type sluice can be reduced, close part gate-type sluice 19, to reduce by 15 revolving speed of water wheels, if gate-type sluice 19 is long-term The state closed in part then considers to replace the larger generator 204 of rated power.

In the present embodiment, multiple water wheels 15 are the settings of water depth direction layering along the river, and reason for this is that more Rainy season, river water level rise steadily and fall after rise, and it is independent of man's will that this, which goes up and falls after rise,；Due to this Embodiment " flood storage " then cannot be used to equably generate electricity as reservoir, if the river water for leaving to go up flows through on ponding, Understand serious waste river water and reduces generated energy；In order to solve this problem it is necessary to which rising, increased flow is all used to as far as possible Power generation, allows generated energy to increase with the rise of river water, although it is unbalanced to do so generated energy, because being belonged to using river water power generation Clean energy resource, and the rise and falling of river water are using a few weeks or months as the period, unlike wind-power electricity generation and solar energy Such generated energy that generates electricity changes as rapidly, so dissolving this part electric energy is feasible compared with wind-power electricity generation and solar power generation； In addition, flow when flow and high water level when due to river water low water level has a long way to go, general available river water high flow capacity is 4 to 5 times of low discharge, if giving water wheels 15 to be equipped with generator 204 according to high water level, in water level and when low water level because water wheels 15 are dynamic Power is insufficient, revolving speed is too low to generate electricity；If a water wheels 15, which are equipped with several generators 204, makes generator with the increase and decrease of flow 204 engage or separate with water wheels 15 and can satisfy water wheels 15 from low water level to high water level and change, still, this again it is easy out Existing two problems: first, operation slightly mistake or control device break down, it just will appear the case where generator 204 overloads, hold Easily lead to the problem of generator 204 is burnt；It needs water wheels 15 extremely firm second, doing so, certainly will need with many steel systems Water wheels 15 are made, this increases water wheels 15 by resistance due to excessively heavy again in low water level, reduces revolving speed, and then reduce generated energy. Therefore, in the present embodiment, multiple water wheels 15 are arranged by layering, are located between bottom plate 16 and vertical plate 17 and form relative closure The river water of constant cross-section product pushes water wheels 15, and river water is made to be divided into multilayer in this way, and every layer of river water impacts one or two water wheels 15, One water wheels 15 outfit, one generator 204, the rated power of every layer of generator 204 be slightly above this layer of high water level flow or Actual power achieved when the maximum flow rate being likely to be breached, in this way, be more than this sheaf space water inlet cross-sectional area water just Flowed into a upper sheaf space, be not in river discharge it is excessive and make generator 204 overload the phenomenon that.

Fix a power generator 20 on each water wheels support frame 14, the input terminal of power generator 20 be fixed on it is same The wheel shaft of water wheels 15 on water wheels support frame 14 is coaxially connected, and power generator 20 includes the clutch 201, ten thousand sequentially coaxially connected To section 202, speed changer 203 and generator 204；The rotation of water wheels 15 drives the generator 204 of power generator 20 to generate electricity, if water wheels 15 revolving speeds are too fast, are more than 204 load of generator, can reduce by 204 input shaft rotating speed of generator by adjusting speed changer 203, it is ensured that Generator 204 can work normally；When needing repairing water wheels 15, first promotes water wheels support frame 14 and water wheels 15 is driven to leave the water surface, Water wheels 15 stop operating, and clutch 201 is recycled to disconnect the connection of water wheels 15 and power generator 20.

Anti- ice raft net 21 is equipped in the river of the side ponding great Kou upstream, anti-ice raft net 21 is V-arrangement, in anti-ice raft net The riverbank below ground of 21 two sides is symmetrically arranged with two pairs of fixed blocks 22, the tip of anti-ice raft net 21 and a pair for being located at upstream riverbank Fixed block 22 by drawing reinforcing bar 23 connect, the both ends of anti-ice raft net 21 respectively be located at downstream riverbank a pair of of fixed block 22 It is connected respectively by drawing reinforcing bar 23.Anti- ice raft net 21 is equipped in the river of the side ponding great Kou upstream, anti-ice raft net 21 Effect is: first, when rising in summer, it can prevent whole big tree from swept away with water flow to destroy ponding and water wheels 15；Second, It is northern China, late autumn and spring, not firm due to freezing, ice raft is often run under the action of water flow, anti-ice raft net 21 can prevent from blocking The impact of dam and water wheels 15 from running ice raft, and eliminate buildup and inhibition is generated to water flow.Anti- ice raft net 21 and water Flowing the angle α between direction is 30 °, and the riverbank below ground in anti-21 two sides of ice raft net is symmetrically arranged with a pair of of fixed block 22, is prevented The two sides of ice raft net 21 pass through drawing reinforcing bar 23 respectively and are fixed on fixed block 22.

The course of work:

Water flow from the upstream flow in river downstream during, first pass around anti-ice raft net 21, filtered out by anti-ice raft net 21 The sundries such as ice or biggish trees are run, its damage to ponding and water wheels 15 is reduced；Then water flow is converged by dam body, Flow velocity is gradually elevated, and the water flow after promoting flow velocity impacts water wheels 15, and water wheels 15 rotate, and kinetic energy is passed to power generation Device 20 generates electricity.

When river water is in lowest water level, the gate-type sluice 19 before water wheel frame lowest level water wheels 15 is in the open state, Other gate-type sluice 19 are all in closed state；If eagre is to not up to upper one layer of water full of this layer of 15 water inlet of water wheels Take turns on 15 water inlets along when, upper one layer of gate-type sluice 19 is not turned on, and at this moment river water temporarily goes up in dam, the original that river water temporarily goes up Because being: this is because the height of ponding and vertical plate 17 is the maximum height that design allows, when dam, inner horizontal is not up to this height When, at this moment the sluice 19 of upper space be close, ponding water inlet flow be greater than water outlet flow, therefore water level it is temporary on Rise.

When eagre to when flooding upper one layer of water wheels 15 completely, upper one layer of gate-type sluice 19, upper one layer of water wheels are opened 15 start to work；River water, which continues to go up, then repeats aforesaid operations method.When river water level is fallen after rise, then contrary operation.

The present embodiment is built a dam with height compared with power station, and the utility model has the advantages of simple structure, is easily constructed, and construction removes, is mobile It is convenient；Ponding height is low, and highest ponding height is lower than two sides ground level, and river water will not go up because of ponding floods ground, to two sides Agriculture-stock production and inhabitation are without influence；Ponding height is low, and in river big flood season, the river water of rise is flowed through from dam, is not determined Dike floods the danger in downstream, highly-safe；It can be suitable for not only building hydro plant with reservoir, narrow terrain river basins to build If can also build in the river basins cannot building hydro plant with reservoir, landform is open, the water conservancy that this part can be left unused is provided Source uses multiple electricity, is the necessary complement of hydro plant with reservoir；Applicability is wide, by a certain range extend ponding away from From while reduce dam body water inlet and water outlet cross-sectional area ratio, the generated energy of the device can be improved, generated energy is big； Since river water is flowed into from inverted "eight" shape ponding, from the relatively small side outlet outflow that is open, the water flow one in entire stroke It is directly in acceleration mode, the rotation of water jet propulsion water wheels solves the problems, such as that bottom of device shoal materials needs periodic cleaning, safeguards Expense is low.

Embodiment 2:

Based on the structure of embodiment 1, change the water inlet cross-sectional area and water outlet cross section that two dam body walls 1 are formed Proportionate relationship between product, it is assumed that river water depth is constant, then the ratio between water inlet cross-sectional area and water outlet cross-sectional area Relationship can be exchanged into the proportionate relationship between water inlet width and water outlet width；The water inlet width and water outlet of test group 1 Ratio between width is 30:3.3, and the ratio between the water inlet width and water outlet width of test group 2 is 30:5, test group Ratio between 3 water inlet width and water outlet width is 30:10；The generated energy of test group 1,2,3 is estimated, is estimated Method is as follows:

Hypothesis test group 1,2,3 is built on same river, and the water inlet of three is located at the same position in river, Ponding water inlet width is 30m, depth of water 1m, water velocity 1m/s at this time, and the water wheels 15 of test group 1,2,3 are wide with its water outlet Width is identical, and 15 axis of water wheels is parallel with the water surface, and 15 radius of water wheels is all 2.5 meters, and provisioned 204 rated speed of generator is all 500r/min, river water trend are linear, and ponding shape is isosceles trapezoid, flow loss and frictional resistance are disregarded, inside and outside ponding Water level is identical.

The water inlet speed of these three test group river waters is set as Vo (m/s), water outlet speed is set as Vt (m/s), the section The acceleration in river is set as a (m/s²), the distance namely displacement of the Duan Shui from water inlet to water outlet is set as X (m), that :

According to the ratio between water inlet width J and water outlet width C it is found that the water outlet width of test group 1 is 3.3m, The water outlet width of test group 2 is 5m, and the water outlet width of test group 3 is 10m；

It is identical from water level inside and outside ponding: water inlet flow (m³/ s)=water outlet flow (m³/ s), flow velocity (m/s)= Flow (m³/ s)/cross-sectional area (m²) it is found that the water outlet flow velocity of test group 1 is 9m/s, the water outlet flow velocity of test group 2 is 6m/ S, the water outlet flow velocity of test group 3 are 3m/s；

Since river flow state all meets uniformly accelrated rectilinear motion in the dam of test group 1,2,3, so, it can be according to even The displacement formula of linear motion is accelerated to find out the displacement of river water in dam.According to: displacement X=(V_t ²- V₀ ²)/2a can be obtained, test group 1 displacement is 40/a (m), and the displacement of test group 2 is 17.5/a (m), and the displacement of test group 3 is 4/a (m).

Because it is that the kinetic energy of the water is doing work that river water, which pushes water wheels rotation, in the dam of test group 1,2,3, meet application Momentum theorem.

According to momentum theorem: 0-FT=0-MV

It arranges: FT=MV

In formula: F is the thrust for impacting water wheels 15, and unit is Kg；T is the time；M is the water that water wheels 15 are flowed through in the unit time Quality, M=flow × specific gravity × T=cross-sectional area × flow velocity × specific gravity × T；

Due to 15 radius 2.5m of water wheels, 15 blade of water wheels absorbs water depth 1m, then, stress point should among water line, by Force radius should be 2m；Torque=F × stress point radius at the stress point；Perimeter=2m × 2 × 3.14 at stress point =12.56m；Water wheels 15 circle required time=12.56m ÷ flow velocity；15 revolving speed of water wheels (r/min)=15 turns of 60s ÷ water wheels The time required to one week；

Assuming that required torque is A, according to power transmission relationship when 204 rated speed of generator is 500r/min Formula, torque ratio are equal to the inverse ratio of revolving speed, obtain: torque × 15 revolving speeds of water wheels=A × 500r/min at stress point；According to generator 204 power, revolving speed, the reduction formula between torque: power (KWh)=torque (Nm) × revolving speed (r/min)/9550, it is known that:

1 generator of test group, 204 power is 2438KWh, annual electricity generating capacity 21356880KWh；

2 generator of test group, 204 power is 1081.9KWh, annual electricity generating capacity 9477444KWh；

3 generator of test group, 204 power is 270.1KWh, annual electricity generating capacity 2366076KWh；

In terms of 0.3 yuan/KWh of market guidance, then 1 annual earnings of test group are 6407064 yuan, and 2 annual earnings of test group are 2843233 yuan, 3 annual earnings of test group are 709822.8 yuan；

From above-mentioned estimation process: first, from the aspect of generated energy and income, in test group 1,2,3, test group 1 Generated energy highest, income also highest；The generated energy and income of test group 1 are 9 times of test group 3, are equivalent to and save test group 3 8 water wheel arrangements；It is 2.25 times of test group 2, is equivalent to 1 water wheel arrangement for saving test group 2.Second, from shift length Relationship between generated energy sees that the displacement X of test group 1 is 10 times of test group 3, is 2.28 times of test group 2, i.e., three Every meter of test group displacement generated energy obtained is of substantially equal.

It analyzes in summary, it can be deduced that such as draw a conclusion:

First, in certain distance, if other conditions are the same, the water inlet cross-sectional area and water outlet of ponding Ratio between cross-sectional area is bigger, and displacement X is longer, then the generating efficiency of river impact type hydroelectric power generating apparatus is higher, income It is more.

Second, since the relationship between shift length and generated energy is, isometric displacement X generated output obtained is basic It is equal.In this way, river very big using the ratio between a water inlet cross-sectional area and water outlet cross-sectional area, that displacement X is very long Flow the design of impact type hydroelectric power generating apparatus, so that it may equal to multiple small ratios, the river impact type hydroelectric power generating apparatus of short essay The summation of design；I.e. in the case where obtaining identical generated output, between water inlet cross-sectional area and water outlet cross-sectional area The design scheme for the river impact type hydroelectric power generating apparatus that ratio is very big, displacement X is very long, it will be able to than water inlet cross-sectional area with The design scheme of ratio very little, the displacement X very river impact type hydroelectric power generating apparatus of section between water outlet cross-sectional area, substantially Degree reduces the quantity of device, such as includes the quantity of water wheels 15, water wheel frame, generator 204 and auxiliary facility, this is with regard to reducing significantly The construction cost and subsequent administration fee of river impact type hydroelectric power generating apparatus.

Third, this test group 1,2,3 assume that river is straight line, although actual river is unlikely to be straight line, but Curved, the scaled ponding of 1,2,3 mode of test group is carried out along its camber on the not bery steep river of camber, The kinetic energy of river water has loss, but losing will not be very big, i.e. generated energy reduction will not be very much, so test group 1,2,3 has in fact With value.

4th, the acceleration a of selected section river water is bigger, then ponding distance needed for obtaining same generated output is got over It is short.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
