Rainwater storage device

Abstract

The invention discloses a rainwater storage device. The rainwater storage device comprises a rainwater reservoir, a guide rod is arranged in the rainwater reservoir and is provided with a first limit block and a floating plate, the first limit block supports the floating plate, a second limit plate is arranged at the top of the guide rod, a connecting plate is arranged at the top of the floating plate, an indicating plate is arranged at the end of the connecting plate, the bottom of the rainwater reservoir is connected with a second water outlet pipe, and the second water outlet pipe is connected to a water storage tank. When the water level of rainwater in the rainwater reservoir in the rainwater storage device continues to rise, the floating plate rises gradually on the guide rod under the action of rainwater buoyancy, at the same time the indicating plate also rises, and staff can know the specific storage quantity of the rainwater in the rainwater reservoir. When the floating plate abuts against the second limit plate, the staff need to open a valve of the second water outlet pipe timely to discharge the rainwater in the rainwater reservoir to the water storage tank, the water level of the rainwater in the rainwater reservoir is effectively controlled, and the situation is prevented that the rainwater overflows from the rainwater reservoir.

Description

technical field [0001] The invention belongs to the technical field of rainwater collection, and in particular relates to a rainwater storage device. Background technique [0002] With the advancement of urbanization, the increase in ground hardening has changed the original hydrological characteristics, resulting in increased rainwater runoff, frequent water accumulation on roads, and frequent large-scale water accumulation in some cities. The decline of the groundwater level has intensified. In addition, the problem of water shortage in my country's cities is becoming more and more serious. The resource-based water shortage in the northern region and the water quality-based water shortage in the southern region. In this environment, the government put forward the goal of building a "sponge city" and supported it in policy, finance and other aspects. [0003] Sponge city, as the name implies, is like a sponge. During the rainy season, it can quickly absorb, accumulate, in...

Problems solved by technology

But at present, in the process of collecting rainwater from urban roads, it is impossible to know the specific storage capacity of water in the rainwater storage tank, which causes rainwater to overflow from the rainwater storage tank.
