Self-cleaning water tank at top of urban building

Abstract

Provided is a self-cleaning water tank at the top of an urban building. A water tank cabin cover is arranged at the center of the top of the water tank, the bottom of the water tank is constructed into a smooth and clean semi-circular pot bottom by cement mortar and masonry materials, an ABS plastic pipe with a four-foot bracket is arranged at the lowest point of the center of the water tank, a section of silica gel hose is connected from the upper end of the pipe to a water outlet tank cover, the flexibility of the ABS plastic pipe connected outside the water tank cabin cover is achieved through the silica gel hose or a stainless steel corrugated bending pipe, the pipes can be bent from the outside of the water tank to be under the surface of the water in the water tank, a pipe body is filled with water, a wooden plug is plugged, the upper end of the water pipe is quickly pulled out of a cover opening of the water tank to be quickly placed on the outer chord of the wall of the water tank, the water level of the water tank is higher than the position of the pipe opening of the ABS plastic pipe when the wooden plug is pulled out due to the fact that no air resistance exists in the pipe, and water can flow out of the ABS plastic pipe on the outer chord of the wall of the water tank through back pressure of water pressure in the water tank due to a water level difference, so thatthe water in the upper, middle and lower layers of the whole water tank circulates with each other, and the water quality of residents reaches a new step.

Description

technical field [0001] The utility model relates to a self-cleaning water tank on the roof of an urban building, and relates to a self-cleaning water tank on the roof of an urban building, belonging to building water supply facilities. Background technique [0002] For water tanks on urban roofs, no matter what its shape is, the water inlet valve is close to the upper line of the carrier, and the outlet valve is about the lower third of the total height of the carrier. First, the probability of fresh water used by the outlet valve is not high. The stagnant water and sediment below the water outlet are difficult to discharge. Over time, more and more components are deposited at the bottom of the flat-bottomed water tank. The water here is in an environment with poor water activity, which leads to local stagnant water quality, which is easy Bacteria are bred, and the sediment with larger particles accumulates at the bottom of the water tank for a long time and becomes a muddy ...

Problems solved by technology

[0002] For water tanks on urban roofs, no matter what its shape is, the water inlet valve is close to the upper line of the carrier, and the outlet valve is about the lower third of the total height of the carrier. The stagnant water and sediment below the water outlet are difficult to discharge. Over time, more and more components are deposited at the bottom of the flat-bottomed water tank. The water here is in an environment with poor water activity, which leads to local stagnant water quality, which is easy Bacteria are bred, and the sediment with larger particles accumulates at the bottom of the water tank for a long time and becomes a muddy paste. Therefore, the water department must drain the dirty water for the water tank at least twice a year, and at most three times a year, clean the sediment at the bottom of the water tank, and return it after cleaning. It needs to be cleaned by an electric pump for rinsing and disinfection, and then new tap water can be put in. During this period, the water needs to be cut off for a long time, which consumes water and labor. Even a lot of sediment can not be discharged with water

This is unfavorable to the optimization of the water quality of residents. How can we solve the difficult problem that the water quality of water tanks on high floors is difficult to guarantee?
