Description

A rainwater collection device on building roof

Technical Field

The utility model relates to the technical field of rainwater collection devices, in particular to a rainwater collection device on a building roof.

Background Art

There are three main forms of rainwater runoff in cities: roofs, roads and green spaces. In urban planning, the green space area required for most land uses is about 30% of the total area, so the roof area occupies a large proportion of the land area, and the collection and utilization of roof rainwater becomes more important.

More and more buildings are equipped with rainwater recycling systems. Rainwater recycling refers to the entire process of rainwater collection. The collected rainwater is used to irrigate crops, replenish groundwater, and can also be used for non-domestic water purposes such as landscape environment, greening, car wash water, road washing cooling water replenishment, and toilet flushing. By collecting and reusing rainwater, water resources can be saved. At present, the existing building rooftop rainwater collection and reuse device has a simple structure, is inconvenient to use, has a poor filtering effect on leaves and debris, and is prone to blockage, resulting in poor rainwater flow and overflow, which greatly reduces the performance.

In this regard, a rainwater collection device on a building roof is proposed to solve the above problems.

A drain pipe is provided at the lower end of the water tank, and the drain pipe is located below the second filter plate, and a drain valve is provided on the drain pipe.

The beneficial effects of the utility model are:

When it rains, the rainwater falls into the water collection box from the water collection port along the eaves of the roof. The first filter plate initially filters large debris such as leaves and then enters the second water outlet pipe through the first outlet pipe and then enters the water storage tank. The water falling into the water storage tank is filtered by multiple second filter plates and can be discharged through the drainage pipe when needed. A sewage pipe is arranged at the lowest point of each second filter plate. When too much sludge remains on the second filter plate and affects the filtration, the accumulated sludge can be discharged through the sewage pipe and the filtration can continue to be used. At the same time, a sewage pipe is slidably connected to the first filter plate. Scraper. When there are too many fallen leaves and the like on the first filter plate to make it impossible to filter, rainwater accumulates in the water collecting tank. After reaching the position of the liquid level meter, the liquid level meter feeds back information to the external controller. The controller controls the motor to rotate, driving the screw to rotate, so that the slider slides left and right, driving the scraper in the water collecting tank to scrape the fallen leaves on the first filter plate to one side for continued use. This solves the problem that the existing rainwater collection device is inconvenient to use, has poor filtering effect on leaves and debris, is prone to blockage, causes rainwater to flow poorly, is prone to overflow, and greatly reduces the performance of use.
