A pumped-storage power generation device using liquid buoyancy is known.

Japanese Patent No. 4349515

  If the passenger / luggage car of the passenger / luggage elevator system is configured to be able to be used as a water pumping tank for power generation, there is a possibility that power generation can be performed more efficiently than with a conventional pumped power generator. . However, in this case, after raising the pumping tank, how quickly the power generation water is supplied to the upper water tank, and how quickly the power generation water collected in the lower water tank via the hydraulic pipe and generator is transferred to the pumping tank. It is necessary to solve the problem of supplying and circulating water.

  In the "pump type power generator using an elevator system" of the present invention, an upper water tank installed at an upper position and a lower water tank installed at a lower position are connected by a hydraulic pipe, and a turbine generator is installed at a lower part of the hydraulic pipe. It is composed of a turbine generator unit that can generate electric power by the power generation water flowing down the hydraulic pipe, and an elevator system pumping unit.The elevator system pumping unit is connected to the turbine generator unit and installed. Is supported by the structure.

  In addition, as the elevator system pumping unit, it is preferable to use a vehicle in which a passenger or luggage car of a passenger or luggage elevator system is replaced with a gantry equipped with a pumping tank for storing power generation water, The pumping tank is made of a lightweight and rugged durable material. At the top of the elevator system pumping section, a tilting fulcrum material that tilts the pumping tank when the pumping tank rises to the height of the upper tank of the turbine generator unit. Is placed at the lower part of the upper water tank side, and a 1 / 4-yen tilting guide is installed on the opposite side, so that the water pumping tank rises to the upper water tank, and then the water pumping tank tilts to the upper water tank side to pump water. The power generation water in the tank is configured to be supplied to the upper water tank, and the height of the wall material on the upper water tank side among the wall materials of the pumping tank is set to be larger than the height of the other wall materials. It is preferred that the.

  Furthermore, when the pumping tank is lowered to the height of the lower tank of the turbine generator unit, water for power generation is supplied from the lower tank to the pumping tank. Water to another pumping tank and wait for replacement) and non-moving water supply, etc., it is preferable to supply water by adopting a quick water supply method from these, and two elevators are operated as a pair, The Unit 1 pumping tank rises from the lower water tank after supplying water for power generation, supplies water for power generation to the upper water tank, makes it possible to generate power, and falls after the water supply is completed. It is preferable that the power generation water is supplied from the Unit 2 pumping tank to the upper tank before the power generation water supplied from the Unit 1 pumping tank rises after the water supply and is supplied from the Unit 1 pumping tank to the upper tank.

  In addition, it is preferable to install a plurality of elevator system pumping units with respect to the turbine generator unit, and further, the turbine generator unit is provided with a lower water tank below and an upper water tank above, and these are connected by a hydraulic pipe. It is preferable that a water flow control valve is provided in the upper part of the hydraulic pipe to control the water flow, and a water turbine generator is installed in the lower part of the hydraulic pipe to generate electric power.

  ADVANTAGE OF THE INVENTION The pumping type power generation apparatus of this invention can be set as the elevator system only of the stand which only mounts and supports the pumping tank without a top plate, and can achieve weight reduction. In addition, by installing a tilting fulcrum material for tilting the pumping tank and a tilting guide of 1/4 yen above the pumping section of the elevator system, the pumping tank after tilting can be tilted, and the water for power generation in a short time can be used. Can be supplied to the upper tank.

  If only one elevator system pumping unit is used, the amount of water obtained by dividing the amount of one pumping operation by the round trip time is the amount of power generated per second, which is inefficient. It is preferable that the unit operates two units in one pair (one set), thereby eliminating time loss and enabling constant power generation.

  The pumped-storage power generator according to the present invention can generate power of a relatively large capacity by installing a plurality of elevator system pumped units with respect to one water turbine-type generator unit. In addition, since the pumped-storage power generation device of the present invention generates power using potential energy at a height difference, it is not necessary to increase the installation area in order to realize large-capacity power generation, and it is possible with a possible sophistication.

Since the pumping power generation device of the present invention circulates the power generation water, there is basically no need to replenish the power generation water (it is sufficient to replenish only the evaporation), and it is very economical. Further, the pumped-storage power generation device of the present invention does not emit CO ₂ and is an environment-friendly power generation device.

  The pumped-storage power generation device of the present invention can constantly generate power regardless of the weather, regardless of day or night. In addition, it does not need to be a mountain area, regardless of the installation location, and it can be of a ground type, underground type, or semi-underground type even on flat land. Furthermore, when the pumped-storage power generation device of the present invention is installed in a factory or the like, an infrastructure transmission and distribution line of a power company is not required, and it is possible to reduce the cost of transmission and distribution equipment and the loss due to voltage drop.

  The power generation gain in the pumped-storage power generation device of the present invention is estimated. The weight of the pumping tank is “500 kg”, the weight of the gantry for mounting and supporting the pumping tank is “100 kg”, the weight of the power generation water stored in the pumping tank is “2400 kg”, the elevator speed is “4 m / sec”, The water discharge time to the upper water tank is calculated as “3 seconds”, the motor capacity as “26 kW”, the head as “42 m”, and the head as “33 m”.

First, the amount of water for power generation Q (seconds)
Q = Pumping tank capacity m ³ / Time required for rising water discharge (lift head m speed 4 m / sec + water discharge time 3 seconds)
= 2.4 / (42/4 + 3)
= 2.4 / 13.5
= 0.177 seconds ^{(m 3} / sec.)
Becomes

Assuming a head H = 33 m and an overall efficiency η = 0.8, the hydroelectric power generation capacity P (kW) is
P = 9.8 × Q (m ³ / sec) × H (m) × η
= 9.8 × 0.177 × 33 × 0.8
= 45.8 (kW)
Becomes

Since the power generation gain (kW) is “hydropower generation capacity−motor capacity”,
= 45.8-26
= 19.8 (kW)
Is obtained.

  When two pairs of elevator system pumping units B are installed for the turbine generator unit A (one unit), 19.8 × 2 = 39.6 (kW), and four pairs of elevator system pumping units B are installed, When 19.8 × 4 = 79.2 (kW) and eight pairs of elevator system pumping units B are installed, 19.8 × 8 = 158.4 (kW), which enables power generation with a relatively large capacity.

In the above calculation of the power generation gain, the head is set to “42 m” and the head is set to “33 m”. However, the calculation is also performed when the head is set to “19 m” and the head is set to “10 m”, and other conditions are not changed. First, the amount of water for power generation Q (seconds)
Q = Pumping tank capacity m ³ / Time required for rising water discharge (lift head m speed 4 m / sec + water discharge time 3 seconds)
= 2.4 / (19/4 + 3)
= 2.4 / 7.75
= 0.309 seconds ^{(m 3} / sec.)
Becomes

Assuming a head H = 10 m and an overall efficiency η = 0.8, the hydroelectric power generation capacity P (kW) is
P = 9.8 × Q (m ³ / sec) × H (m) × η
= 9.8 × 0.309 × 10 × 0.8
= 24.2 (kW)
Becomes

Since the power generation gain (kW) is “hydropower generation capacity−motor capacity”,
= 24.2-26
= -1.8 (kW)
And the power generation gain is negative. Therefore, in order to generate power using the pumped-storage power generation device of the present invention, it is necessary to set the head and the head to a sufficient height.
