Ecological type water-saving three-dimensional gardening greening system easy to maintain

Abstract

The invention discloses an ecological type water-saving three-dimensional gardening greening system easy to maintain. The ecological type water-saving three-dimensional gardening greening system easyto maintain comprises a vertically-arranged drainage pipe and at least one planting pot body arranged on the drainage pipe, and an open window is formed in the outer wall of the drainage pipe; a waterstorage tank and a planting tank are arranged in the planting pot body, a water inlet which communicates with the open window is formed in the upper side wall of the water storage tank, and the planting tank is arranged above the water storage tank; a water taking part is arranged in the water inlet, and is provided with a water taking opening capable of extending into an inner cavity of the drainage pipe to receive rainwater; the water taking part is connected with a driving part; and the size of the rainwater receiving opening of the water taking opening is reduced along with the rise of the water level in the water storage tank. Compared with the prior art, the drainage pipe is a vertically arranged straight pipe and has the advantage that rainwater drainage is smoother. The planting pot body can be refitted and installed on an existing drainage pipe and does not need to be specially arranged on a bent pipeline, so that the adaptability of three-dimensional greening planting is greatly expanded, and installation is more convenient.

Description

technical field [0001] The invention relates to the field of exterior wall gardening and greening, in particular to an ecological, easy-maintenance, water-saving and three-dimensional gardening and greening system. Background technique [0002] Compared with rural environments, land resources in cities are relatively scarce, and generally flowers and plants can only be planted on the ground, which limits the green area of ​​the city. In order to solve the problem of land shortage for greening, Chinese patent CN105532287B discloses an exterior wall drainage structure for three-dimensional greening, by setting bent rainwater pipes and planting grooves on the rainwater pipes to plant plants, and the rainwater is collected through the rainwater branch pipes on the rainwater pipes into the water tank. The rainwater in the water storage tank is absorbed by the planting soil layer where the plants are located through the evaporated water vapor when it is not raining. [0003] How...

Problems solved by technology

[0003] However, the installation of bent rainwater pipes greatly increases the smoothness of rainwater drainage. When the rainwater in the storage tank reaches the storage height, the rainwater still needs to be drained downwards along the bent rainwater pipes, which may easily cause poor drainage of rainwater on the roof. Accumulated water increases the burden on the roof
