JP2011017196A - Rainwater controlling and rainwater power generating down pipe - Google Patents

Abstract

PROBLEM TO BE SOLVED: To solve such problems that: a conventional power generator has been installed in a river or a water passage as there has been no facility for easily generating small power, using rainwater, which is needed for electronic control or there has been no facility for achieving stable power generation at a fixed flow rate of rainwater irrespective of constantly changing rainfall intensity; there has been no power generating facility that is installed in a down pipe itself though there has been a power generator using rainwater; and there has been no facility that moves a control electronic circuit utilizing the rainwater for power generation by using the rainwater in the down pipe.SOLUTION: A water collecting and filtering tank is connected to an upper part of a general down pipe. A power generating down pipe is installed to supply rainwater to a lower power generator arranged at the position where an effective head can be obtained. The rainwater is filtered by the water collecting and filtering tank, and overflowed when needed. The rainwater is temporarily retained in a temporary reservoir by a siphon etc., and is allowed to fall at a burst at a fixed flow rate. Power is generated only when the rainwater falls, and is utilized by a rainwater utilization control electronic circuit.

Description

  The present invention relates to downpipe, rainwater storage tank, rainwater power generation, and rainwater utilization control electronic circuit.

Conventional generators were installed in rivers and waterways.
There was power generation using rainwater, but none was installed on the vertical shaft itself.
None of the power generation by rainwater in the downside moved the control electronics for rainwater utilization.

There was no facility to easily generate low power required for electronic control by rainwater.

Despite rainwater whose rainfall intensity is constantly changing, there was no facility to realize stable power generation at a constant flow rate.

Connect to the upper side of the general downpipe, and install a downpipe for power generation that supplies rainwater to the generator at the position where you can earn an effective head below. It is filtered by a water collection filtration tank and overflowed as necessary. In a temporary storage tank, rainwater is temporarily stored by a siphon or the like and falls at a fixed flow rate. It is used in electronic circuits that generate electricity only when rainwater falls and control various uses of rainwater.

The system that automatically distributes rainwater for multiple purposes, such as rainwater used for greening, rainwater outflow suppression, rainwater collected for emergencies, sprinkler water, etc., is automatically and efficiently controlled.
It functions even when the power supply stops without using the supplied power, contributing to CO2 reduction.
Information can be transmitted and received wirelessly.
An information pulse can be obtained 30 minutes before the guerrilla heavy rain from the net, and a separate rainwater tank can be emptied in advance to prepare for runoff control.

Since rainwater is temporarily stored, it can contribute to the suppression of runoff.

It is possible to supply a small amount of power to drive an emergency information network.

It can be easily installed without causing clogging of the gutter, making it easy to spread.

Overall configuration of rainwater control rainwater power plant Configuration diagram of rainwater utilization control electronic circuit

Overall configuration.
Rainwater control with a system that connects a collected water filtration tank to the upper part of a general downpipe, and supplies the collected rainwater through a temporary storage tank to a generator at a position where it can make an effective head drop through the downpipe for power generation. Rainwater power plant. The generated power is used in the rainwater utilization control electronic circuit.
For example, replace the trout section of the school roof on the rooftop of the school with a water collection filtration tank, install a temporary storage tank in the walkway on the 4th floor, connect the effective head of the 3rd floor with a power generation vertical fence, and It is possible to use it by installing a generator on top and generating electricity.

Catchment filtration tank 1
It has a circuit that eliminates substances that damage the generator through a filter such as ceramic, and overflows during heavy rain.

Temporary storage tank 2
A tank that temporarily stores rainwater until it accumulates to some extent. When stored above a certain amount (HWL in the figure) by various siphons according to the amount of stored water, such as a float type siphon or a double siphon, it is discharged at a constant flow rate. In the figure, when the water level drops to LWL, the supply stops and water is accumulated until HWL is reached. Repeat this.

Power downboard 3
A vertical shaft for power generation that connects the effective head from the temporary storage tank to the generator. It is assumed that the pressure loss due to the bent part is small, the expansion of the piping is small, and the pressure loss is small. An aluminum three-layer cross-linked polyethylene pipe that can be flexibly bent is used.

Generator 4
If the roof area that receives rain is about 100 square meters, it can generate about 50 w at a height of 10 m. However, it is about 1w or less if it becomes annual. However, if this level of output is available, the generator can be used for electronic control and communication systems.

Rainwater utilization control electronic circuit 5
A control circuit that controls power storage, information transmission / reception, and electromagnetic valves.
