Multifunctional ecological type outdoor water storing device

Abstract

The invention relates to a roof water storing device, in particular to a multifunctional ecological type outdoor water storing device. The structural key points are that the multifunctional ecological type outdoor water storing device comprises a rainwater treating house, an outdoor water collecting tank and a root empty space layer, the rainwater treating house is arranged in the middle of the bottom of a pond and embedded into an upper floor slab of the empty space layer, a rainwater filtering net is arranged at the periphery of the rainwater treating house and at the position close to the bottom of the pond, a filtering and sterilizing system, a tap water inlet valve, a waste water ball valve, a waste water pipe and a water supply pipe are arranged in the rainwater treating house, the waste water pipe is connected with a recycled water system of a building to be matched with the waste water ball valve to supplement the outdoor water storing device in the situation without rainwater, the water supply pipe extends out of the rainwater treating house and is connected to floor users, and water supply openings are correspondingly formed in the water supply pipe. The multifunctional ecological type outdoor water storing device has the advantages of collecting rainwater, effectively reducing urban heat island effect, relieving water draining burden of building water draining pipes, preventing a roof from ponding, greatly reducing burden to an urban water draining system, effectively utilizing one part of rainwater and facilitating the environment and ecology.

Description

technical field [0001] The invention relates to a roof water storage device, in particular to a multifunctional ecological outdoor water storage device. Background technique [0002] In the current urban environment, due to dense buildings, which account for about one-third of the urban area (excluding rivers), when it rains, especially when it rains heavily or torrentially, the top of the building is also the main place to receive rain. First of all, the rainwater needs to be discharged through the drainage pipe of the building, and the drainage pipe is generally located on the outer wall of the building and runs through the entire height of the building. Once it is cracked, it is easy to affect the wall of the building, and it is inconvenient to maintain. Scaffolding is required . Secondly, the design of the top surface of each building is different. The drainage of the top surface of most buildings is not ideal. It is easy to accumulate water, breed mosquitoes, and cause...

Problems solved by technology

First of all, the rainwater needs to be discharged through the drainage pipe of the building, and the drainage pipe is generally located on the outer wall of the building and runs through the entire height of the building. Once it is cracked, it is easy to affect the wall of the building, and it is inconvenient to maintain. Scaffolding is required

Secondly, the design of the top surface of each building is different. The drainage of the top surface of most buildings is not ideal. It is easy to accumulate water, breed mosquitoes, and cause a messy environment. The building layer is easily damaged, which will cause water seepage to the roof of the top floor residents, which will bring great inconvenience to life

Finally, although the current air quality is poor, the quality of rainwater in the rainy southern cities is still relatively good. It is also a great waste to let such a large amount of rainwater drain from the roof.
