JP2013238128A - Water circulation type hydraulic power generation system - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a method of hydraulic power generation in which water is sucked up from a river or a water tank if there is water whatever in any condition, the water is dropped with a head drop to generate power, used energy is small, efficiency is high, and the water is used over and over again.SOLUTION: In an image of a water circulation type hydraulic power generation system, when a decompression pump 1 for a decompression water chamber is operated after a device is installed, the internal pressure of the decompression water chamber becomes lower. As the internal pressure becomes closer to vacuum, a water surface in the decompression water chamber elevates so as to become closer to an upper surface in the decompression water chamber. Then if a decompression pump 2 for a decompression water storage chamber is operated, the internal pressure of the decompression water storage chamber becomes lower. When the internal pressure becomes closer to the vacuum, the water in the decompression water chamber enters the decompression water storage chamber through a check valve 4 for a decompression water storage chamber. The entered water falls into a hydraulic power generator 7 through a water feed pipe to generate power. In the present invention, the head drop required to generate power can be acquired even if the water that has been pumped up and used for power generation is returned to a water tank or a river from which the water is pumped up.

Description

In recent years, the myth of nuclear power generation has fluctuated and power has fallen short of the importance of power saving.
The necessity is screamed. Recently, not only companies, but also general households,
Cooperation and efforts to save electricity have become indispensable. There are various ways to save electricity, such as solar power generation and LED lighting.

In order to make up for the power shortage, the thermal power stations that are not in operation are restarted. However, due to the high fuel costs, there are calls for higher electricity prices.

Fuel costs are low and efficient power generation is urgently needed. Hydropower is the cheapest and most efficient power generation in Japan.

JP 1986-215463 discloses hydropower generation using Pascal tube.

Japanese Patent Application No. 2012-023800 expresses my thoughts on a hydroelectric power generation system using the decompression method.

Japanese Patent Application No. 2012-023800

In order to save Japan's crisis, Japan, which has abundant water resources, must increase its hydropower generation.

The reasons for the lack of growth of hydroelectric power generation include the fact that the power transmission line is long and maintenance is inadequate due to the water rights, landscape and remote areas.

Water rights are not involved, the landscape is not damaged, the transmission line is short, and
If maintenance can be done easily, hydroelectric power generation will be installed throughout Japan.
It will save the current energy crisis in Japan.
To that end, it is necessary to somehow secure the amount of water and the drop of water, which is the installation condition of the hydroelectric generator. It has long been known to use the siphon principle to raise water and drop it to make a head,
In that case, if the discharge destination was a tank that was sucked in and another tank, it would not have been low.
The water used for power generation is permanently circulated without being thrown away to secure the amount of water,
By moving to the desired height with less energy and dropping it, you can get the required head, make a device that can be installed anywhere and generate electricity,
It is a challenge.

A decompression water chamber is provided in the water, and the decompression water chamber has a top surface closed,
The lower surface is open and has a decompression water storage chamber on the side and a decompression pump for the decompression water chamber on the upper surface.

  The decompression reservoir has a decompression pump for decompression reservoir, an air vent valve on the upper surface, and a check valve for the decompression reservoir and water pipe on the side.

The depressurized water chamber and the depressurized water storage chamber have a water passage hole, and are fitted with a check valve for the depressurized water chamber that feeds the water only from the depressurized water chamber to the depressurized water chamber. The water pipe is characterized by having a gate valve, a check valve and a hydroelectric generator.

When the decompression pump for the decompression water chamber is operated after installing the device, the internal pressure of the decompression water chamber decreases, and when the vacuum is approached, the water level in the decompression water chamber rises and approaches the upper surface of the decompression water chamber. I will come. Here, when the decompression pump for the decompression water storage chamber is operated, the internal pressure of the decompression water storage chamber decreases and approaches the vacuum.
The water in the decompression water chamber enters the decompression reservoir through the check valve for the decompression reservoir. The incoming water passes through the water pipe, falls to the generator, generates electricity,
The water that has been generated is merged with the original water, reused, and recycled.
Secure the amount of water.

This device is installed everywhere where there is water, such as a water tank, water tank or river, sucks up water, drops a generator head from above, drops water, and generates electricity. The present invention is that the head required for power generation can be obtained even if it is returned to the sucked water tank or river. Once the water used for power generation is returned to the original tank,
Instead of throwing it away, it can be reused to secure the amount of water generated. If it is installed in a place with water, it will start generating electricity 24 hours a day, 365 days all over Japan.

Embodiments of the present invention will be described below with reference to the drawings.
The drawing in Fig. 1 is an image of a water-circulating hydroelectric power generation system.
After installing the device, operating the vacuum pump 1 for the vacuum chamber will decrease the internal pressure of the vacuum chamber. As you approach the vacuum, the water level in the decompression water chamber rises up and approaches the top surface in the decompression water chamber. Here, when the decompression pump 2 for the decompression reservoir is operated, the internal pressure of the decompression reservoir decreases. When approaching the vacuum, the water in the decompression water chamber enters the decompression reservoir through the check valve 4 for the decompression reservoir. The incoming water passes through the water pipe and falls to the hydroelectric generator 7 to generate electricity. The water after power generation merges with the original water,
It is reused and recycled to ensure the water volume.
The feature of this invention is that even if water sucked up and used for power generation is returned to the sucked water tank or river, the head required for power generation can be obtained.
The water pipe has a gate valve 5, a check valve 6 and a hydroelectric generator 7.
