The gravity storage power generation device comprises a vertical cylinder block, a vertical pipe line and a pump turbine. The pump turbine comprises an electrical motor and a pump body, wherein impellers are arranged in the pump body, and the impellers are connected with the electrical motor through spindles; a gravity piston is arranged in the vertical cylinder block, and the vertical cylinder block is communicated with the bottom of the vertical pipe line through a communicating pipe; a water return pipe is arranged on the top end of the vertical pipe line, and the water return pipe is connected with the pump body; the pump body is connected with the vertical cylinder block through a water outlet pipe; the electrical motor is connected with a power system through a change-over switch; and a plurality of sealing rings are arranged on the gravity piston. The gravity storage power generation device can store excessive electrical energy in the form of gravitational potential energy in the gravity piston during the period of electricity consumption valley time, and effectively avoids the waste of the electrical energy, and satisfies the electrical energy requirement of an electrical energy consuming unit at any time.

Description

The gravity energy-storage electricity generating device
Technical field
The utility model is a kind of energy accumulation electricity generator, particularly a kind of gravity energy-storage electricity generating device that utilizes gravitational potential energy.
Background technique
The use of electric energy exists the difference of peak times of power consumption and low power consumption phase, and such as in 1 year, be peak times of power consumption summer, and be the low power consumption phase winter; In one day, be peak times of power consumption daytime, is the low power consumption phase at night; In many occasions, often be that the peak period electric power supply is not enough, the low ebb phase then electric energy have a surplus, when electric power supply is not enough, manyly have to have a power failure with electric unit, cause economically or otherwise loss; And electric energy is when having a surplus, thermal power plant hydroelectric power station still can close some units, but it is so lucky that wind energy power, solar electrical energy generation, power generation with marine energy just do not have, because their generating is subjected to the impact of season, meteorology, regional condition, have obvious discontinuity and unadjustable property, they still continue to generate electricity and cause the situation of waste of energy during the phase so will appear at low power consumption.
Summary of the invention
The purpose of this utility model is not to be wasted and to invent and a kind ofly can lay in the gravity energy-storage electricity generating device that gets up to wind energy, solar energy, ocean energy at low ebb phase electricity in order to solve generating at low power consumption wind energy, solar energy, ocean energy during the phase.
The purpose of this utility model realizes as follows: described gravity energy-storage electricity generating device, comprise vertical cylinder body, vertical pipe and pump turbine, pump turbine is comprised of motor and the pump housing, be provided with impeller in the pump housing, impeller is connected with motor by rotating shaft, be provided with gravity piston in the vertical cylinder body, the bottom of vertical cylinder body and vertical pipe was connected by connecting tube, the top of vertical pipe is provided with return pipe, return pipe is connected with the pump housing, the pump housing is connected with vertical cylinder body by outlet pipe, and motor is connected with electrical network by reverser.
Described gravity piston is provided with a plurality of seal rings.
Good effect of the present utility model is as follows: the utility model electric energy that the low power consumption phase is unnecessary is stored in the gravity piston with the form of gravitational potential energy, has effectively avoided the waste of electric energy, has guaranteed with electric unit at any time to the demand of electric energy.

Embodiment
As shown in Figure 1, described gravity energy-storage electricity generating device, comprise vertical cylinder body 1, vertical pipe 2 and pump turbine 3, pump turbine 3 is comprised of motor 4 and the pump housing 5, be provided with impeller 6 in the pump housing 5, impeller 6 is connected with motor 4 by rotating shaft 7, be provided with gravity piston 8 in the vertical cylinder body 1, the bottom of vertical cylinder body 1 and vertical pipe 2 was connected by connecting tube 9, the top of vertical pipe 1 is provided with return pipe 10, return pipe 10 is connected with the pump housing 5, and the pump housing 5 is connected with vertical cylinder body 1 by outlet pipe 11, and motor 4 is connected 13 by reverser 12 with electrical network.
Described gravity piston is provided with a plurality of seal rings 14.
Must be added with sealing medium water in vertical cylinder body and the vertical pipe in the use.
During low power consumption, by reverser motor is connected with the output terminal of electrical network, the unnecessary electric energy of electrical network namely passes through the motor driving pump housing, at this moment pump turbine is to use as water pump, water pump is evacuated to the water on gravity piston top in the vertical pipe, and then be back to the bottom of gravity piston, along with the water on gravity piston top constantly is drawn out of, the pressure on gravity piston top will reduce gradually, gravity piston will rise gradually, the electric energy that electrical network is unnecessary converts the potential energy of gravity piston to thus, finishes the process of electrical thermal storage.
During peak of power consumption, pass through reverser, motor is connected with the input end of electrical network, and at this moment gravity piston moves down under Action of Gravity Field, and WATER AS FLOW MEDIUM enters the pump housing by return pipe, impeller in the pump housing then drive motor rotates, at this moment pump turbine is to use as water turbine, and the generating of water turbine drive motor just stops power generation process until gravity piston falls to cylinder bottom, the motor electricity directly leads to electrical network, when replenishing peak of power consumption to the demand of electric energy.
