Description

  This invention is a rainwater storage tank for effectively using rainwater as miscellaneous water by diverting and storing rainwater from a fence that is a drainage facility for rainwater that falls on the roof of a building. Publicly, it relates to rainwater storage tanks that serve as individual storage facilities for runoff control, which is one of the comprehensive flood control measures.

  Conventional rainwater storage tanks have complicated rainwater collecting facilities, whether they are dug into the ground or installed underground.

Problems to be solved by the invention

This has the following drawbacks.
(B) When installing in the basement, the ground must be excavated, and costs for that are required, and in existing residential land, the places where excavation is possible are limited.
(B) When installed in the basement, facilities such as a pump are required to pump up the stored rainwater.
(C) Even when installed on the ground, water collection facilities are complex and cannot be installed easily.
The present invention has been made to eliminate these drawbacks.

Means for solving the problem

The rainwater storage tank main body (1) consists of an upper part and a lower part. The upper part is a 90 ° bend pipe (3) (4) that allows rainwater to flow in and out on a straight line, and overflows when the lower part is full. The overflow weir (5) for making it easy, the filter layer (6) for simply purifying the rainwater, the storage part, the faucet (10) for taking out as miscellaneous water in the lower part, the interior for the maintenance is emptied A drain cock (11) is provided, and a connecting pipe (9) for taking rainwater from the upper part to the lower part is provided.
The present invention is a rainwater storage tank configured as described above.

The invention's effect

This has the following effects.
(B) Since it is not installed underground, installation is easy and no pumping equipment is required.
(B) It can be installed simply by cutting the existing trough (2) by several tens of centimeters and joining the cut surface and the inflow / discharge 90 ° bent pipe (3) (4).
(C) The appearance of the rainwater storage tank main body (1) is simple.
(2) Rainwater can be easily purified by the filter layer (6).
(E) When the lower part is full or clogged with the filter layer (6), it overflows the overflow weir (5) and returns to the trough (2), so there is no fear of leaking outside.
(F) The stored rainwater can be used as miscellaneous water.
(G) Because it can temporarily store rainwater, it has a flood control function.
The present invention brings about these effects.

BEST MODE FOR CARRYING OUT THE INVENTION

The rainwater storage tank body (1) has a 90 ° curved pipe (3) (4) that can flow in and out on a straight line, and rainwater that has fallen from the ridge (2) is a 90 ° curved pipe for inflow (3) The water flows into the rainwater storage tank main body (1), usually passes through the filter layer (6), falls down from the connecting pipe (9), is stored in the lower layer, and is taken out from the faucet (10) as miscellaneous water. When the lower layer is full of water, it overflows from the overflow weir (5) and is discharged from the discharge 90 ° bent pipe (4) to the trough (2).
The present invention has the structure as described above. The rainwater storage tank main body (1) can be installed, and the rainwater storage tank main body (1) is selected by selecting the ridge (2) that can collect the rainwater most from the roof. The rainwater that is stored is effectively used as miscellaneous water. In addition, the interior will be emptied to allow for flood adjustments so that as much rainwater as possible can be stored before rainfall.

Claims (1)

  The rainwater storage tank main body (1) consists of an upper part and a lower part. The upper part is a 90 ° curved pipe (3) (4) that allows inflow and discharge of rainwater in a straight line, and overflows when the lower part is full. Overflow weir (5) A filter layer (6) for easily purifying rainwater is provided, the lower part is a storage part, a faucet (10) for taking out as miscellaneous water, and the interior is emptied for maintenance By providing a drain cock (11) and a connecting pipe (9) for taking rainwater from the upper part to the lower part, it is possible to effectively use rainwater as miscellaneous water and to prevent outflow control as one of comprehensive flood control measures. Rainwater storage tank that serves as a storage facility.
