Description

The backflow formula hydroelectric installation that draws water

Technical field

The invention belongs to the hydraulic power generation technology field, refer in particular to a kind of backflow that is used for ordinary water power station formula hydroelectric installation that draws water.

Background technique

At present, general hydroelectric generator mostly is to utilize natural water-head, and water level was produced when the water level potential energy of upper pond was transported to lower reservoir kinetic energy and potential energy convert electric energy to through hydroelectric generator, single electricity generate function.

Summary of the invention

The backflow that the purpose of this invention is to provide and a kind ofly do not need extra pumping equipment, is used for the ordinary water power station formula hydroelectric installation that draws water.

The objective of the invention is to realize like this:

The backflow formula hydroelectric installation that draws water; Include upper storage reservoir, (general water power plant does not have lower storage reservoir to be lower than the lower storage reservoir of upper storage reservoir; But buffer pool is arranged; Storage capacity is less), the conduit pipe in the UNICOM between the lower storage reservoir and be installed in the hydroelectric power plant that the hydroelectric power unit on the conduit pipe is formed; Have more than one hydroelectric generator to be the generating and the dual-purpose machine that draws water in the described hydroelectric power unit, the conduit pipe between UNICOM's upper storage reservoir and the hydroelectric power unit is provided with gate valve through the water intake UNICOM of arm and each hydroelectric generator on each arm.

The above-mentioned generating and the dual-purpose machine that draws water pass through conduit pipe and lower storage reservoir as the water intake of suction engine time spent bottom UNICOM.

The above-mentioned generating and the dual-purpose machine that draws water pass through conduit and upper storage reservoir UNICOM as bottom UNICOM, the water outlet that the water intake of suction engine time spent passes through conduit pipe and lower storage reservoir.

External output electric energy, the formula of drawing water were internally imported the conversion equipment of power supply when the lighting outlet of the stator coil of the above-mentioned generating and the dual-purpose machine that draws water was provided with generating.

The present invention compares the outstanding and beneficial technical effects of existing technology:

1, the present invention utilizes generating and the dual-purpose machine that draws water not only can generate electricity but also principle that can pumped storage; In the generator set in a power station, an above generator is used the hydraulic turbine generator (for example mixed flow pump water turbine) that not only can generate electricity but also can draw water; To replace special-purpose suction engine; Practiced thrift build a station cost and occupied ground and space, needn't take huge fund and set up pumped storage power station.

2, the utilization of the present invention hydraulic turbine generator that not only can generate electricity but also can draw water is when low power consumption; Rise in the upper storage reservoir water in the lower storage reservoir subsequent use with it; Have more than is needed electric energy converts water to and can be stored in the upper storage reservoir in the time of can be with a large amount of low ebb; The present invention can optimize electric network composition, strengthens electrical network peak load shifting ability, effectively reduces the operation overall cost.

3, the present invention can according to the unnecessary electric weight of lower storage reservoir storage capacity size and electrical network paddy electricity what, the design electric motor power is to reach several times to tens times of original hydro-power station generate output.

Description of drawings

Fig. 1 is a structural principle schematic representation of the present invention, and the direction of arrow is water (flow) direction among the figure, and after dotted arrow represented that gate valve is closed, suction pump was the situation that upper storage reservoir supplies water from the lower storage reservoir water lift.

Embodiment

The present invention is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1:

The backflow formula hydroelectric installation that draws water; Include upper storage reservoir 11, be lower than on the lower storage reservoir 12, UNICOM of upper storage reservoir 11 conduit pipe 20 between the lower storage reservoir and be installed in the hydroelectric generator station that the hydroelectric power unit on the conduit pipe 20 is formed; Described hydroelectric power unit 30 is made up of several hydroelectric generators 31,32; There is more than one hydroelectric generator 32 to be the generating and the dual-purpose machine that draws water in the described hydroelectric power unit 30; Conduit pipe 20 between UNICOM's upper storage reservoir 11 and the hydroelectric power unit 31 is provided with gate valve 33 through the water intake UNICOM of arm 21 with each hydroelectric generator 31,32 on each arm 24; The words of conditions permit; Can say the hydraulic turbine generator that all the hydroelectric generator 32 whole employings in the hydroelectric power unit 30 not only can have been generated electricity but also can draw water; The just described generating and the dual-purpose machine that draws water, like this, when low power consumption; All generators all convert electric pump to; Through best endeavors the water in the lower storage reservoir is risen in the upper storage reservoir subsequent usely, have more than is needed electric energy converts water to and can be stored in the upper storage reservoir in the time of can be with a large amount of low ebb, will play positive impetus to macro adjustments and controls, the energy saving of national energy.。

The above-mentioned generating and the dual-purpose machine that draws water pass through conduit pipe 20 and lower storage reservoir 12 as the water intake of suction engine time spent bottom UNICOM.

Through conduit and upper storage reservoir 11 UNICOMs, water intake and water outlet when the above-mentioned generating and the dual-purpose machine that draws water generate electricity as the water intake of suction engine time spent and water outlet and conduct are just in time opposite as bottom UNICOM through conduit pipe 20 and lower storage reservoir 12 of the water intake of suction engine time spent, water outlet for the above-mentioned generating and the dual-purpose machine that draws water.

The above-mentioned generating and the dual-purpose machine that draws water are a kind of existing technologies, and for example: maximum in the world mixed flow pump water turbine is loaded on Bremen storage station of Germany, 237.5 meters at its water turbine head, generator power 660 megawatts, 125 rev/mins of rotating speeds; 247.3 meters of pump heads, motor power (output) 700 megawatts, 125 rev/mins of rotating speeds; The patent document of announcing for CN101806243 number " a kind of device with dual purpose of generating power and pumping water " also discloses a kind of structure of the dual-purpose machine that generates electricity and draw water, and this is not describing the dual-purpose machine that therefore generates electricity and draw water one by one again as existing technology.
