Rainwater collecting and recycling device for building

Abstract

The invention discloses a rainwater collecting and recycling device for a building. The rainwater collecting and recycling device comprises a box with an opening in the top face and a blade roller, aplurality of rotating shafts are in the box, a strip-shaped plate is arranged outside the rotating shafts, a rack is outside the box, an air cylinder is connected to one end of the rack, a connectingrod is hinged to the other end of the rack, sliding grooves formed in the two sides of the inner wall of the box, sliding blocks in the sliding grooves, a guide sleeve is on the back face of the box,a movable rod penetrates the guide sleeve, the sliding blocks are connected through a first filter screen, a second filter screen is arranged below the first filter screen, and screen baskets are arranged in front of and behind the second filter screen. The device is started according to the rainfall, rainwater is not collected when the rainfall is small, rainwater is not hindered from nourishinga greening zone, the device is started when the rainfall is large, the impact force of the rainwater can be reduced through the blade roller, ground pits at a water outlet can be avoided, the impact force of the rainwater is fully utilized for movement of the strip-shaped plate and the first filter screen, energy is saved, when the strip-shaped plate is closed, external dust, animal waste and thelike can be prevented from entering the box body, and pollution to the interior of the box body is avoided.

Description

technical field [0001] The invention belongs to the field of water recovery, in particular to a device for collecting and reusing rainwater used in buildings. Background technique [0002] According to the current building structure, the outer surface of the building is equipped with drainage pipes to drain the rainwater accumulated on the roof to the ground. For buildings with green belts around them, the rainwater is usually discharged into the green belt without greening The belt usually flows into the drainage channel along the ground. The drainage channel is connected in many ways, and the source of drainage is unclear. Furthermore, it is very likely to contain animal urine or even feces, so it is difficult to recycle. Generally speaking, the rainwater from the roof is discharged Sometimes it only carries dust, gravel, etc., which is less polluting and has a high recycling value. However, the current water collection settings are not perfect enough to effectively collec...
