Abstract
The utility model discloses a system in hydropower station for water entering, water circulating and water discharging. The utility model is characterized in that the diameter of a water inlet pipeline is changed after the water blocked by the dam of the hydropower station passes through the water inlet, enters into the water guiding channel and flows into the flooding dam; the original diameter is reduced by 50 percent and an angle below 40 degree is added so as to make the water after changing the diameter just can flows through half of the vane of the hydro-turbine and impact the hydro-turbine to generate electricity; the tail water flows to a strobe through the water discharging pipeline; the strobe blocks the tail water and makes the tail water can not flow to the river but just can reversely flow to the water storing well which can be high; the upward side of the water storing well is provided with a water pump room which is provided with a pipeline so as to be connected with the water of the water storing well; the water pump room is provided with another pipeline so as to be connected with the flooding dam through a tee. After being boosted, the water of the water storing well returns to the flooding dam of the water guiding channel through the water pump and the water pump pipeline so as to impact the hydro-turbine to generate electricity. If the tail water strobe is opened, the tail water does not circulate any longer but flows to the lower reach of the river through the water discharging pipeline.
Description
(1) technical field:
The utility model relates to the water inlet of a kind of water power plant, circulating water, and the system of sluicing,
(2) background technique:
At present, the building water power plant all is to select rivers, and at the middle building dam of rivers, dam blocks height to water, and high water enters catchment channel through water intake, flows into overfall dam, the impulse water turbine generating, and the tail water of process water turbine flows to the river by sluice pipe.
Traditional prior art entering catchment channel, does not flow into overfall dam, and the water of impulse water turbine generating utilizes again, all is to make the tail water through water turbine flow to the river by sluice pipe.
(3) summary of the invention:
The purpose of this utility model provides the water inlet of a kind of water power plant, circulating water, and the system of sluicing solves the defective that prior art exists.
Model utility technical problem to be solved: the water inlet of a kind of water power plant, circulating water, the system of sluicing.
The technological scheme that the technical problem that solves adopts: a kind of water power plant water inlet, circulating water, the system that sluices, it is characterized in that the water process water intake that the water power plant dam is blocking, enter catchment channel, flow into overfall dam, the impulse water turbine generating, tail water flows to gate one by sluice pipe, gate stops tail water, make tail water can not flow to the river, diverted flow is to the retaining well, and the retaining well can be very high, a pumping station is arranged above the retaining well, pumping station has pipeline to be connected with the water of retaining well, and pumping station has pipeline to be connected with overfall dam in addition, and connection is to lead to one 3 to connect.After the water of retaining well improves, being connected and getting back in the overfall dam of catchment channel impulse water turbine generating again through water pump and water pump pipeline.
Another feature of the present utility model is the arrangement of water turbine, 3 intake pipes that lead to after connecing become diameter, dwindle original diameter 50% and increase the angle below 40 °, make the water that becomes behind the diameter can only flow through the half of blade of water turbine, promote the fast turn-around of water turbine.
If open tail lock, not recirculation of tail water flows to lower reaches of river by sluice pipe.
The beneficial effects of the utility model are that the tail water through water turbine is flowed to the gate obstruction of the water in river by sluice pipe by sluice pipe, make the tail water diverted flow to the retaining well, utilize fully again again.
(4) description of drawings:
Fig. 1 is the water inlet of a kind of water power plant, circulating water, the system schematic of sluicing.
Fig. 2 is the water inlet of a kind of water power plant, circulating water, and the system water turbine of sluicing is settled schematic representation.
(5) embodiment:
The water inlet of a kind of water power plant, circulating water, the system of sluicing:
Dam water intake 8 is connected with dam catchment channel 9, and the gate 1 of dam catchment channel 9 and dam catchment channel is connected.
The water of the gate 1 of dam catchment channel is by overflow pipe, through the intake pipe 10 behind the change diameter, intake pipe 10 behind the change diameter is to dwindle original diameter 50% and increase the angle 11 below 10 °, flow to hydraulic turbine generator 2 again, second half bridge wall wall 12 and one 's 1/4 circle 13 protection hydraulic turbine generators 2 generate electricity under the impact of water, in 90 °, the water turbine of 8 blades rotates 22.5 °, and the ratio of water that enters the half of blade of water turbine is 3: 1; The water turbine of 12 blades rotates 15 °, and the ratio of water that enters the half of blade of water turbine is 5: 1; The water turbine of 16 blades rotates 11.25 °, and the ratio of water that enters the half of blade of water turbine is 7: 1; Tail water after the generating flows to the gate 3 of dam sluice pipe through sluice pipe 14.
The gate 3 of dam sluice pipe is closed or part is closed, and the tail water diverted flow of process water turbine is to retaining well 4, and dam retaining well has height, and the water pipe of water pump is connected with the retaining well easily.
Dam pumping station 5 has pipeline that the tail water of retaining well is extracted out, and delivers in another pipeline and the dam circulating water pipeline 6 power of water pump and water turbine draining power match.
Another pipeline and dam circulating water pipeline 6 are discharged tail water to pumping station and are turned back in the overfall dam pipeline, and any one is connected dam circulating water pipeline and overfall dam pipeline, and connection is to lead to one 3 to connect.
Tail water circulates repeatedly, repeated stock water turbine generating ... ...
