Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0015] A pumping energy storage device, artificially constructing a pile foundation (10), a cap (11), a column (6), a lower pool (3), an upper pool (4), and the upper pool (4) through beams or supports (9 ) is placed on the top of the column to achieve the height difference required for energy storage. Build struts (7) to keep the column (6) stable, and build anchor spindles (12) and cable wind ropes (8) if necessary, so that the column (6) can be maintained more effectively. An electric motor (generator) (1), a water pump (water turbine) (2) and a water pipe (5) are installed as equipment for energy storage and energy release.

[0016] The energy storage process is as follows: during the low electricity consumption period or when energy storage is required, the motor (1) obtains electricity from the wire (13), drives the water pump (2) to ex...

Abstract

The invention discloses a water-pumped water storage device, belonging to the technical field of energy storage and aiming at overcoming the defects that special geographic resources are needed in site selection of the traditional water-pumped energy storage power station. An upper pool is directly placed in altitude through artificially-built pile foundations, upright columns, beams or supports, hawsers and other structures to form an attitude difference required by energy storage rather than utilizing natural terrain. Compared with the traditional water-pumped energy storage power station, the invention can realize super capacity of energy storage, no pollution and energy storage application with low cost as well, but has the advantages of less occupying area, more flexible site selection, wide application range, no need of migration, no plough flooding, and the like, is suitable for matching with wind power, photovoltaic power generation and the like and ensures that power output is more stable and easily dispatched, reducing impact to a grid and reducing wastes.

Description

technical field [0001] The invention relates to the technical field of energy storage, in particular to a pumped water energy storage device. Background technique [0002] Electric energy has the advantages of large-scale production, easy conversion into other forms of energy, long-distance transmission, centralized management, automatic measurement and control, etc. However, there are changes and mismatches in time and space in the generation and use of electricity, requiring energy storage facilities. The energy storage of electric energy is more difficult. Wind and photovoltaic power generation are the main sources of energy in the future, but wind and photovoltaic power generation are both random and difficult to dispatch, requiring the cooperation of energy storage facilities. Energy storage technology is a major issue in the future utilization of new energy. [0003] Ordinary pumped storage power station is a large-capacity energy storage method with an energy cycle ...
