Japanese Patent No. 4349515

If the passenger/luggage car of the passenger/luggage elevator system can be used as a water pumping tank for power generation, it may be possible to generate electricity more efficiently than conventional pumped-storage power generators. .. However, in this case, how quickly the power generation water is supplied to the upper tank after raising the pump tank, and how quickly the power generation water collected in the lower tank via the penstock/generator is transferred to the pump tank It is necessary to solve the problem of whether to supply water and circulate it.

The "pumping-up type power generator using the elevator system" of the present invention is such that an upper water tank installed at an upper position and a lower water tank installed at a lower position are connected by a water pressure pipe, and a water turbine generator is installed below the water pressure pipe. The elevator system pumping unit is connected to the turbine generator unit, and is installed by connecting the elevator system pumping unit to the turbine generator unit. Is characterized by being supported by a structure.

Incidentally, as the elevator system pumping section, it is preferable to use a passenger or baggage basket of an elevator system for passengers or luggage, in which a cradle equipped with a pumping tank for containing water for power generation is replaced. The pumping tank is made of a material that is lightweight and durable, and is a tilting fulcrum material that tilts the pumping tank when it rises to the height of the upper tank of the turbine generator unit at the upper part of the elevator system pumping section. Is placed in the lower part of the upper water tank side, and by installing a tilting guide of 1/4 yen on the opposite side, the pumping tank is raised to the upper water tank, and then the pumping tank is tilted to the upper water tank side, The power generation water in the tank is configured to be supplied to the upper water tank, and the height dimension of the wall material on the upper water tank side of the wall material of the pumping tank is set to be larger than the height dimension of other wall materials. Preferably.

Furthermore, when the pumping tank descends to the height of the lower tank of the turbine generator unit, the water for power generation is supplied from the lower tank to the pumping tank, and parallel movement to the lower tank and pumping tank replacement (during system rising) There is a water supply to another pump tank and waiting for a change) and non-moving water supply, and it is preferable to adopt a quick water supply method to supply water, 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, and the power generating water is supplied to the upper water tank to make it ready for power generation, and it descends 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 water tank before the power generating water supplied from the Unit 1 pumping tank to the upper water tank disappears from the upper water tank after the water supply.

In addition, it is preferable to install a plurality of elevator system pumping units for the turbine generator unit.In addition, the turbine generator unit has a lower water tank below and an upper water tank above, and these are connected by hydraulic pipes. It is preferable that a water amount control valve is provided on the upper part of the water pressure pipe to adjust the water amount, and a water turbine generator is installed on the lower part of the water pressure pipe so that power can be generated.

INDUSTRIAL APPLICABILITY The pumped-storage power generation device of the present invention can be an elevator system having only a pedestal for mounting and fixing and supporting a pumping tank without a top plate, and can reduce the weight. Also, by installing a tilting fulcrum material for tilting the pumping tank and a 1/4 yen tilting guide above the pumping section of the elevator system, the pumping tank after tilting can be tilted, and the water for generating water can be generated in a short time. Can be supplied to the upper water tank.

If there is only one elevator system pumping unit, the amount of water generated by dividing one pumping amount by the round-trip time is the power generation amount per second, which is inefficient. It is preferable that the unit operates two units in a pair (one set), which eliminates time loss and enables constant power generation.

The pumped-storage power generator of the present invention can generate a relatively large amount of power by installing a plurality of elevator system pumped-up parts for one turbine-type generator device part. In addition, since the pumped-storage power generation device of the present invention generates electric power by the potential energy of the height difference, it is not necessary to expand the installation area to realize large-capacity power generation, and it is possible with the possible advancement.

Since the pumped-storage power generator of the present invention circulates the power generation water, basically there is no need to replenish the power generation water (it is sufficient to replenish only the vaporized portion), 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.

INDUSTRIAL APPLICABILITY The pumped-storage power generation device of the present invention is capable of constant power generation regardless of the day and night regardless of the weather. Further, it does not have to be installed in any place and does not need to be a mountainous area, and even on a flat land, it can be an above-ground type, an underground type, or a semi-underground type. Furthermore, when the pumped-storage power generation device of the present invention is installed in a factory or the like, the infrastructure company's infrastructure transmission and distribution lines are not needed, and it is expected that the cost of power transmission and distribution equipment and the loss due to voltage drop will be reduced.

A trial calculation of the power generation gain in the pumped storage power generation device of the present invention will be made. The weight of the pumping tank is "500 kg", the weight of the platform 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", Calculation is performed assuming that the water discharge time to the upper water tank is "3 seconds", the electric motor capacity is "26 kW", the lift is "42 m", and the head is "33 m".

First, the amount of power generation water Q (second) is
Q = pumping tank capacity m ³ / rising water discharge required time (lift m ÷ speed 4 m/sec + water discharge time 3 sec)
=2.4/(42÷4+3)
=2.4/13.5
= 0.177 seconds (m ³ /second)
Becomes

Assuming that the head H is 33 m and the total efficiency η is 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 "hydroelectric power generation capacity-motor capacity",
=45.8-26
= 19.8 (kW)
Is obtained.

If 2 pairs of elevator system pumping section B is installed for the turbine generator unit A (1 unit), 19.8×2=39.6 (kW), if 4 pairs of elevator system pumping section B are installed, When 19.8×4=79.2 (kW) and 8 pairs of elevator system pumping section B are installed, it becomes 19.8×8=158.4 (kW), and it is possible to generate a relatively large capacity.

In addition, in the above calculation of the power generation gain, the head is "42 m" and the head is "33 m", but the head is "19 m", the head is "10 m", and other conditions are not changed. Then, first of all, the amount of water for power generation Q (second) is
Q = pumping tank capacity m ³ / rising water discharge required time (lift m ÷ speed 4 m/sec + water discharge time 3 sec)
=2.4/(19÷4+3)
=2.4/7.75
= 0.309 seconds (m ³ /second)
Becomes

Assuming that the head H is 10 m and the total efficiency η is 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 "hydroelectric power generation capacity-motor capacity",
=24.2-26
=-1.8 (kW)
And the power generation gain becomes negative. Therefore, in order to generate electricity by the pumped-storage power generation device of the present invention, it is necessary to set the pumping head and the head to a sufficient height.
