Description

  The present invention relates to a structure that is installed in the middle of a rainwater pipe and reliably diverts only relatively clean rainwater, and a rainwater utilization system that effectively uses rainwater using this structure.

  Recently, the installation of a system that stores and effectively uses rainwater, which is a bounty of nature and is gentle to nature, has been flourishing, and water has been sprayed onto car wash and garden flower beds.

  Conventionally, Patent Document 1 and Patent Document 2 are known as structures that reliably divert dirty initial rainwater so as not to flow into the rainwater storage tank.

  In addition, it is not possible to prevent dirty initial heavy rainwater from going to the rainwater storage tank, but it is possible to divert only rainwater that falls to the initial small amount so as not to go to the rainwater storage tank. Document 4, Patent Document 5, and Patent Document 6 are known.

Patent Document 6 is known as a structure that returns rainwater that cannot flow into the rainwater storage tank to the branch structure when the rainwater storage tank is full.

The conventional technologies in Patent Document 1 and Patent Document 2 have a structure in which dirty initial rainwater is reliably diverted so as not to go to the rainwater storage tank, but the initial rainwater pool that achieves the purpose is located outside the branch structure. The structure is very complicated.
Conventional techniques in Patent Document 3, Patent Document 4, and Patent Document 5 are technologies that can divert only rainwater that falls in a small amount of dirty initial water so as not to go to the rainwater storage tank. When there is a large amount of rainfall, dirty rainwater flows into the rainwater storage tank, and this is an incomplete technology that contaminates the stored water in the rainwater storage tank.
The technique in the conventional patent document 6 is an incomplete technique that pollutes the stored water in the rainwater storage tank by flowing the dirty rainwater to the rainwater storage tank when there is a sudden heavy rainfall at the beginning of the rain. In addition, when the rainwater storage tank is full, there is no flow in the direction of the branch pipe, and the rainwater is returned to the branch structure regardless of the stored water in the rainwater storage tank.
The problem to be solved by the invention is to reliably drain the dirty initial rainwater, store the relatively clean water in the rainwater storage tank, and use the clean water in the rainwater storage tank, which tends to be dirty, as overflow water to the branch structure. The structure to be returned is to develop a simple structure in which only the inside of the pipe is processed in a form similar to a branch pipe having a general appearance structure.
The problem to be solved by the present invention is to eliminate the above problems.

  In order to supply and drain rainwater etc. to the rainwater storage tank with a single pipe, a partition plate that divides the branch pipe of the branch structure installed in the rainwater pipe vertically is installed, and the upper part of the partition plate is the water channel, the lower part of the partition plate Is a drainage channel, and the partition plate of the branch pipe is extended into the main pipe of the branch structure and bent downward, and the partition board is installed extending in the vertical direction toward the lower side of the main pipe, and below the extended partition board. The tip is bent to the opposite side of the main drainage channel and closed to the inner wall of the main pipe to make a shielding plate. A rainwater pool is installed in the pipe above the shielding plate, and a small outlet is installed at the bottom of the shielding plate. The rain water flow structure is provided as a means for solving the problem.

The effect of installing the partition plate according to the first embodiment of the present invention is that rainwater is supplied to and drained from the rainwater storage tank with a single pipe by separating the inside of the branch pipe of the branch structure up and down by the partition plate. There is an effect that can.
The rainwater pool is installed by extending the partition plate of the branch pipe into the main pipe of the branch structure and using the lower end as a blocking plate to store dirty initial rainwater, a small amount of rainwater, and fine earth and sand at the bottom of the rainwater pool. From the installed small outlet, it is possible to gradually flow rainwater and fine earth and sand together, and the rainwater storage tank has the effect of being able to draw the upper, relatively turbid water.
Even if the rainwater storage tank is frozen a little and the rainwater does not enter the rainwater storage tank, there is an effect that it can flow around the tip of the partition plate in the branch pipe as long as rainwater flows.

The effect of installing the slide pipe according to the second embodiment of the present invention is that a bypass drain pipe is provided below the upper drain pipe by installing a slide pipe that can be freely moved up and down and freely stopped. There is an effect that it can be recombined to form a structure with anti-freezing specifications in cold regions.
There is an effect that it is possible to easily remove dust such as fallen leaves by installing a slide tube in the upper part of the main pipe of the branch structure.

  The effect of installing both Y pipes in Example 3 of the present invention is that by installing both Y pipes, one branch of both Y pipes is used as a dust outlet, and usually a lid is used to prevent rainwater leakage. This prevents the garbage from being collected by simply removing the lid.

  The effect of the rainwater utilization system according to the fourth embodiment of the present invention is that a branch structure is installed in the middle of the rainwater pipe and water is taken in to reliably remove dirty initial rainwater, a small amount of rainwater and fine earth and sand. Is connected to the upper side wall of the rainwater storage tank, the inside of the branch pipe is divided up and down by a partition plate, the upper part of the partition plate is used as a water supply channel, and the lower part of the partition plate is used as a drainage channel, and the water supply to the rainwater storage tank and the rainwater storage tank are full. At this time, it acts to agitate and discharge fresh water in the rainwater storage tank, and a rainwater cock can be provided at the bottom of the rainwater storage tank to effectively use the rainwater.

  The best mode for carrying out the rain-water flow structure of the present invention is to partition the inside of the branch pipe of the branch structure installed in the rainwater pipe up and down in order to supply and drain the rainwater to the rainwater storage tank with a single pipe. The upper part of the partition plate is used as the water supply channel, the lower part of the partition plate is used as the drainage channel, the partition plate of the branch pipe is extended into the main pipe of the branch structure, bent downwards, and substantially in the vertical direction toward the lower side of the main pipe The partition plate is extended and installed, and the lower end of the extended partition plate is bent to the opposite side of the main drainage channel and closed to the main wall of the main pipe.
