Description

  The present invention relates to a pressure accumulating power generation facility that accumulates air using surplus power at night and generates power during the day using the accumulated air. Moreover, this invention relates to the high airtight gate suitable for the said accumulator type power generation equipment.

  Conventionally, an accumulator type power generation facility is available (for example, Patent Document 1). The above-mentioned conventional pressure accumulator type power generation facility uses an underground river, rainwater storage facility, etc. as an upper pond, and water from the upper pond is led to a water pipe inside the pit through a connecting waterway, and stored in a reservoir in the lower pond below the pit. Then, compressed air produced by midnight power, solar power generation, wind power generation, etc. is sent to the water tank of the lower pond through the air pipe, and the same amount of water as the air capacity is transferred from the water tank to the underground river of the upper pond through the water pipe.・ It pushes up to rainwater storage facilities, etc. to maintain atmospheric pressure, and sends compressed air stored in the reservoir in the lower pond to the gas turbine on the ground when it needs electricity to burn and generate electricity.

  Such an accumulator type power generation facility requires a storage tank as a lower pond in addition to an underground river and rainwater storage facility as an upper pond, so that the facility becomes large and the cost is high.
