[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an energy storage structure, that is, a structure capable of converting electric power into potential energy of a building and converting the potential energy into electric power for use.

[0002]

2. Description of the Related Art Since power consumption peaks during the day and decreases at night, it is desired to average the power consumption day and night.

Conventional energy storage means include pumped-storage power generation, which converts electric energy into potential energy and stores it.
That is, pumped-storage power generation is known in which pumps are operated using excess power at light load to pump up and store water in a reservoir at a high place, and the water is dropped at peak load to obtain hydroelectric power. .

Further, as a method of storing energy using a building, a thermal storage air-conditioning technology is known in which thermal energy is stored in a structural body using surplus electric power at night and the air-conditioning load during the day is reduced by the thermal energy.

However, in the case of pumped storage power generation, large-scale dedicated facilities and equipment, transmission and distribution lines, and the like are required, so that it cannot be implemented in an urban area.

When a building is used to store thermal energy, the thermal energy has a property of being dissipated unless vacuum insulation is provided, which is a drawback of the storage structure.

[0007] Therefore, the present invention uses the building structure itself as a potential energy storage mechanism and applies the potential energy stored using nighttime power to daytime power use, thereby standardizing the power consumed in facilities. Therefore, the above-mentioned problem is to be solved.

The variable space floor 15 is variable because the upper floor slab 17 moves up and down as the movable structure 2 moves up and down. Basement floor
Each of the floor 1c and the ground floor 1a is a general floor whose floor height does not change.

In the variable space floor 15 between the fixed structure 10 and the movable structure 2, it is necessary to secure the allowance for expansion and contraction of elevators, stairs, and the like.

According to the first to fifth aspects of the present invention,
The whole or a part of the building 1 is a movable structure 2 formed to be mechanically movable up and down, and the movable structure is lifted with surplus power at night to convert the electric energy into potential energy and store it. In addition, in the daytime, the lifting / power generation device 3 that generates power based on the stored potential energy by using the restoring force of the movable structure 2 due to gravity is provided. By storing the energy in the building 1 and supplementing the necessary electric energy during the day, the amount of power purchased during the day can be reduced to standardize the power consumption, and at the same time, the total energy cost can be reduced. . At this time, the potential energy is not of a dissipative nature, and the stored energy can be reused 100%, so that an energy storage mechanism with less waste can be obtained. Further, the present invention can be implemented easily and without hindrance even in an urban area by using the building 1.

In addition, according to the second aspect of the invention,
The power generating device 3 is provided with a hydraulic device 4 with a brake that pushes up the movable structure 2, an oil storage tank 5 containing oil to be supplied to the hydraulic device with the brake, and an oil accumulator 6 with the oil in the oil storage tank.

Furthermore, according to the fifth aspect of the present invention, the staircase structure for entering and exiting the first floor of the movable structure at the ascending position can be simplified. That is, in the case of a normal inclined stair, the distance in the oblique direction from the lower end to the upper end of the inclined stairs increases as the movable structure rises, and the lower end of the inclined stairs approaches the upper end of the inclined stairs as the movable structure descends, and the distance becomes shorter. Therefore, it is quite difficult to form the inclined stairs in which the distance in the diagonal direction expands and contracts in this manner. Since the length of the helical direction is changed, the formation is easy.
