(57) Abstract:

The invention relates to hydropower and is designed to regulate and maintain a stable mineralogical composition of the reservoirs by pumping fluid from the reservoirs with a different arrangement of the levels of liquid in them, as well as for the energy of the pumped fluid to drive vehicles and electricity generation. The method of pumping liquid from the reservoirs with a different arrangement of the fluid is that the fluid is pumped from the first reservoir to the second through the intermediate reservoir, the liquid level which is higher than in the first and second reservoirs. Use the second reservoir with the fluid level below the liquid level in the first reservoir. The liquid is removed from the warmer upper layers of the first and intermediate reservoirs and released into the lower layers of the second, which contributes to maintaining a stable mineralogical composition of the water. 5 C.p. f-crystals, 2 Il.

The invention relates K hydro and can be used to regulate and maintain a stable hydrological, mineralogical and thermal regimes of reservoirs by pumping fluid from the water and in various fields of power generation to compensate for the energy consumption, associated with the pumping liquid.

There is a method of pumping fluid, implemented when working pumped storage plant that contains two upper and one lower reservoir (basin), United pressure piping with a reversible hydraulic units. During the "peak" load water is discharged from the upper reservoirs in the lower and the process of electricity generation. In the period of "failure" load units operate in pumping mode and the water from the lower reservoir is served in one of the upper reservoirs or both of the reservoir, with water from one of the upper reservoir can get for irrigation and water supply (see, USSR author's certificate N 853145, IPC 7 F 03 In 13/06, 21.09.1981). However, with this method of pumping fluid cannot provide for the regulation of hydrological, mineralogical and temperature of the reservoir, it fails to account for the process of evaporation from reservoirs located at different levels.

The closest analogue to the claimed method of pumping fluid from reservoirs with a different arrangement of fluid levels is the method lies in the fact that the liquid is pumped from the first reservoir to the second through the intermediate reservoir, the level of the liquids is above the liquid level in the first reservoir, U.S. patent N 4132901, IPC 7 F 03 13/12, 02.01.1979).

However, this method does not allow for stable hydrological, mineralogical and thermal regime in waters, it does not take into account the evaporation of the liquid, the liquid from the intermediate reservoir is taken from the lower layers, and is produced in the upper layers of the second reservoir, which does not contribute to enriching the water with oxygen. In addition, this method does not provide the energy use of the fluid to drive the vehicle.

The technical result of the invention is to improve the stability of the hydrological, mineralogical and thermal regime of the reservoir by reducing the influence of evaporation on the mineralogical composition of the liquid in the reservoirs, as well as the possibility of using the energy of the fluid to drive the vehicles and generate electricity to offset the energy costs associated with pumping fluid.

This technical result is achieved due to the fact that in the method of pumping liquid from the reservoirs with a different arrangement of fluid levels, namely, that the liquid is pumped from the first reservoir to the second through intermediate widout the second reservoir with the fluid level below the liquid level in the first reservoir, the liquid is removed from the warmer upper layers of the first and intermediate reservoirs and release layers of the second reservoir, in particular in its lower layers. The energy of the fluid can be used to power the actuators of the vehicle and/or unit. Pumping fluid can be made by piping, the upper surface of the latter cover the roadway for the passage of ground transportation. As additional vehicles can use the funicular.

In addition, storm water is collected in a sump located between the intermediate reservoir and the first reservoir, and pumped them into the intermediate reservoir.

In Fig. 1 shows a circuit for implementing the method of pumping fluid; Fig. 2 - section a-a in Fig. 1.

The method of liquid transfer is carried out as follows.

Fluid is pumped from the first reservoir 1 to the second reservoir 2 through the intermediate reservoir 3, the liquid level which is higher than in the first and second reservoirs 1 and 2, the liquid level in the second reservoir 2 feature below the liquid level in the first reservoir 1. The liquid is removed from the warmer upper layers of pernickety used to power the actuators 4 vehicles 5 and/or unit 6. Pumping liquid carry to line 7 and 8, the upper part of which cover the road surface 9 for the passage of, for example, the wheel of the vehicle 5. As an additional vehicle may be used funicular.

To ensure movement of the vehicle 5 used drive turbines 10 placed in the pipe 7 between the reservoir 1 and the intermediate reservoir 3, or from the power unit 6 installed at the outlet of the pipe 8. The electricity generated from the liquid discharge hydraulic unit 6 allows at least partially offset the cost of energy to drive the pump (pumps) 11 mounted on the pipe 7 between reservoirs 1 and 3.

The pipes 7 and 8 can be performed with a variable cross-section of reinforced concrete, for sampling fluid from the warm upper layers of the reservoirs 1 and 3 can be used with a wide mouth with an open top. For transmitting rotation from the shaft of the turbine 10, with its location in the pipe 7 or 8 can be used sealed couplings 12, located in the wall, the pipes 7 and 8 can be performed end-to-end niche posted by who and or pulley 13. Water from the intermediate reservoir 3 can be used for irrigation and water supply. Water from the upper layers of the reservoirs 1 and 3 and the release at the bottom colder layers of the reservoir 2, allows to provide a stable hydrological, mineralogical and temperature, adjust the temperature in the reservoirs and to enrich the liquid oxygen. At small altitude differences between reservoirs 1, 2 and 3 you can use a siphon effect with pre-initiating paging of the pipes 7 and 8, for example, the pump 11 and the hydraulic unit 6 operating in the pumping mode.

Between the intermediate reservoir 3 and the first reservoir 1 may be located a sump (not shown), which collect storm water, which is also pumped through the intermediate reservoir 3 to the second reservoir 2.

For pump operation (pump) 11 can be used non-traditional renewable energy sources, for example, the energy of wind waves in the reservoir 1 and/or wind turbines.
