Description

The importance of obtaining power from natural energy, especially using the flow of rivers, has been talked about for a long time.
It is not easy to grow.

If you try to install hydropower facilities, water rights, equipment costs, location conditions,
It is cited as a reason why hydroelectric power generation facilities do not grow due to damage to the landscape and problems with the length of transmission lines.

Japanese rivers are usually quiet, but they begin to rampage when the amount of water increases due to heavy rain or typhoons. As countermeasures, large and small sluice gates have been established throughout the river.

The present invention provides a method for attaching hydroelectric generators to many sluice gates in Japan so that they can be used for hydroelectric power generation. When it becomes possible to easily attach and remove hydroelectric generators to the sluice gates, problems such as water rights, equipment costs, location conditions, and damage to the landscape will be solved all at once.

JP 2010-65675 discloses a sluice-type generator that generates electricity by moving the turbine up and down according to the amount of water.

JP 2005-351246 discloses a structure in which a generator is installed inside the lower part of the sluice, and water is completely blocked by the sluice, allowing water to pass only through the generator passage.

Patent No. 4134277 is composed of two inventions. One method is to generate electricity by turning a turbine in the overflow water of the weir. Another method is to make a hole in the bottom of the gate plate, install a housing, and store the impeller in it, and then extend it up from the impeller with a drive shaft and connect it to the generator.

When I watched a TV program recently, a big river sluice came out.
It has been said that it has never moved because there has been no flood for the past four years.
The sluice gate that was built with a large amount of construction costs does not move once for four years.
It ’s a big loss. Some sluice must be used effectively.
The sluice is made firmly and sturdy by calculating the strength so that it can withstand water pressure. Attach a slide rail and detachable device to the sluice,
Slide the slide rail, set the hydroelectric generator on the detachable device so that it protrudes from the bottom of the sluice, and lower it to the place where the sluice is submerged in water, so that the impeller of the hydroelectric generator also soaks in the water, The impeller was turned on,
Generate electricity. If you install hydroelectric generators at sluices throughout Japan and generate electricity, you can make great electricity.

Because the surface layer flow of the river is used for power generation, a lot of garbage flows. It is necessary to take measures against garbage. And because the water drop is small, big power generation is not possible, but the width of the sluice is long,
I think that it is better to install many small hydroelectric generators.
The cost of 1KW100 units is lower than that of 100KW units, and the effect will be improved if it can be easily maintained as a detachable hydroelectric generator.
Attach a hydroelectric generator and a dust eliminator that can be easily attached and detached to a sluice that is only used during floods and irrigation, etc., and always lower the sluice to near the water flow, and immerse the hydro power generator in the water flow to generate electricity. The challenge is to come up with a method.

The impeller of the hydroelectric generator is set on the downstream side of the lower sluice by setting a removable hydroelectric generator so as to protrude from the lower part of the sluice, lowering the sluice, and immersing the impeller of the hydroelectric generator in a water flow. Is rotated by the water stream to generate electricity.

Attach a removable dust guard and a movable gate that moves up and down on the upstream side of the sluice.

A generator slide rail is extended vertically from the upper part on the downstream side of the sluice to the bottom of the sluice, a generator attaching / detaching device is attached between the end of the generator slide rail and the bottom of the sluice, and the generator slide rail is slid. , Set the hydroelectric generator on the generator attachment / detachment device so that it protrudes from the bottom of the sluice.

From the upper part on the upstream side of the sluice gate, vertically extend a trash guard slide rail to the bottom of the sluice gate, attach a trash guard detachment device between the end of the trash guard slide rail and the bottom of the sluice gate, and Slide the scraper slide rail and set the dust guard to the dust guard attaching / detaching device. The dust guard is a piece of metal connected in a chain shape in the form of goodwill. The length of the dust guard is covered by the water flow to protect the impeller of the hydroelectric generator set in the lower part of the sluice downstream.

A movable gate that is movable up and down is attached to the upstream side of the sluice in a position that does not interfere with the dust-proofing machine, and its movable range is the same position as the lower end of the sluice and the lower end of the movable gate before the movement. And when the movable gate is moved downward, the lower end of the movable gate is attached so as to protrude from the lower part of the sluice gate, down to a parallel line of the lower end of the impeller of the hydroelectric generator. Come and reduce the water flow other than flowing into the hydroelectric generator, and increase the water pressure flowing into the hydroelectric generator to increase power generation efficiency.

The hydroelectric generator attached to the sluice is detachable and can be easily lifted to improve maintainability.

By installing a dust eliminator on the upstream side of the hydroelectric generator, the underwater trash that is a major enemy of the hydroelectric generator is kept away.

By installing a movable gate upstream of the hydroelectric generator, the amount of water entering the hydroelectric generator can be increased, increasing generator efficiency.

If the sluice can be used effectively and the amount of power generation increases, natural energy can be recovered, contributing to power shortages.
