station comprising
an upper reservoir 1 located at the upstream water level and the lower end thereof
connected to the first pressurized shaft 2;

unit; said second power station unit 6 is a unit with 4 million kw.

In the embodiment, as shown in the drawing, between said gravel processing plant 9 and
the second power station unit 6 are provided with a power transmission shaft 10 and a
hanging object transportation and ventilation shaft 11.
In the embodiment, as shown in the drawing, a hanging object ventilation shaft 12 is

enlarge the reservoir capacity and power station installed capacity, making developing clean
DESCRIPTION
energy efficiency break through the traditional building approach of pumped storage power
station; the use of two storage stations,"ground station' and "underground station" storage
power station pumping power plant, three reservoirs "upper reservoir, middle reservoir, lower
reservoir", can facilitate the transfer of water, water replenishment, improve the flexibility in
development of clean energy.
Wherein, the use of natural rivers as upper reservoirs, lower reservoir as underground
cave depots with ship lock to put water into the underground cave depots during the abundant
water period, not only can generate power, but also can reserve water, that is, to avoid
flooding and also to recover the abandoned water, that is, to recover energy; in the dry period,
the water from the underground cave depots will be pumped back to the upper reservoir
(natural rivers, etc.) for replenishment, which can facilitate shipping during the dry period;
In the case of a station site suitable for building a pumped storage power station, the
installed capacity is more than twofold larger than the traditional mode, and the reservoir
capacity is more than twofold larger; there are already economic benefits when selling or
using cavern-mined stone for project construction. After the pumped storage power station is
built, the reservoir capacity of the lower reservoir is also increasing due to the progress of
cave mining, so the reserved energy will increase accordingly. This is far beyond the
traditional method of arranging pumped storage power station projects.
The invention and its embodiment have been described above, but the description is not
limited thereto; only one embodiment of the invention is shown in the drawings, and the
actual structure is not limited thereto. In general, it is to be understood by those skilled in the
art that non-creative design of structural forms and embodiment that are similar to the
technical solutions without departing from the spirit of the invention shall all fall within the
protective scope of the invention.
