Rainwater recovery device for green building

Abstract

The invention discloses a rainwater recovery device for a green building. The device comprises a device body, a liquid storage chamber, a cover plate, a first vortex spring, a drain outlet and a second vortex spring, the liquid storage chamber is fixedly installed at the lower end of the device body, the cover plate is connected to the upper end of the device body, and a circular gear is fixedly connected to a transmission rod. A traction rope is fixedly installed below the inner end of a movable filter plate, the lower end of the traction rope is connected to a center rod in a winding mode, alateral gear is fixedly installed on a driving rod, a transmission bevel gear is installed at the inner end of the driving rod, and a driving bevel gear is installed at the lower end of the transmission bevel gear. According to the device, when rainwater is recycled, impurities filtered out from the interior can be conveniently and timely discharged to the exterior of the device, blockage of an internal filtering structure is avoided, meanwhile, the external impurities can be blocked to a certain extent, and the possibility that a large amount of rainwater evaporates in sunny days can be reduced.

Description

technical field [0001] The invention relates to the technical field related to green buildings, in particular to a rainwater recovery device for green buildings. Background technique [0002] With the country's advocacy of energy saving, green and environmental protection, people's awareness of environmental protection is gradually deepening. However, as one of many building types, green buildings have many advantages such as health, comfort, safety, durability, and resource conservation. The realization of green buildings It is related to the unique climate conditions, natural resources and cultural environment of each region. In order to improve the full utilization of resources, some green buildings usually recycle rainwater in rainy days, so as to make subsequent use of the collected rainwater. In order to effectively improve the efficiency of rainwater collection, most of them will set up rainwater recovery devices under the eaves of green buildings, and the rainwater r...

Problems solved by technology

[0007] The purpose of the present invention is to provide a rainwater recovery device for green buildings, to solve the above-mentioned background technology, most of the current market requires manpower to regularly disassemble and clean the internal filter device, thus increasing the labor force. After a long period of use It is easy to block the internal filter device due to insufficient cleaning, and it is not convenient to block the external impurities when it needs to be used, which will cause some external impurities such as fallen leaves to fall into the device and be trapped inside the device. A large amount of accumulation can easily cause the interior of the device to be polluted, and at the same time, it is easy to cause a large amount of evaporation of recovered rainwater due to the high external temperature when it is sunny
