Water collection type green roof structure

Abstract

The invention discloses a water collection type green roof structure which comprises a roof; the roof is provided with a planting region used for planting plants; the position, corresponding to the planting region, of the roof is fixed with a rain shelter; the rain shelter comprises a ceiling; the ceiling is uniformly provided with rain leakage through grooves around the circumference; a shutter is rotationally connected to the ceiling and comprises a rotary barrel and multiple plate bodies which are fixed with the rotary barrel and are used for covering the rain leakage through grooves; the center of the ceiling is provided with a water storage cavity; a water receiving barrel is vertically connected to the interior of the water storage cavity in a sliding manner; the middle part of the inner wall of the water storage cavity is provided with an elastic supporting block for performing initial temporary supporting on the bottom of the water receiving barrel; and the water receiving barrel is provided with a linkage mechanism for linking the plate bodies to close the corresponding rain leakage through grooves when moving downward. By adopting the water collection type green roof structure, rainwater enters the structure through the rain leakage through grooves in a rainy day; when the rainfall capacity is relatively large, after the weight of deposited water in the water receiving barrel reaches a certain degree and the water receiving barrel overcomes a clamping force of the elastic supporting block, the water receiving barrel can slide downward to the bottom of the water storage cavity to drive the shutter to rotate until the plate bodies close the corresponding rain leakage through grooves, and overmuch rainfall capacity is avoided from entering the planting region.

Description

technical field [0001] The invention relates to the field of roofs, more specifically, it relates to a water-collecting green roof structure. Background technique [0002] With the continuous development of society, more and more attention has been paid to the ecological environment. In order to improve the urban ecological environment, roof gardens, roofs, and roof gardens have really entered the scope of urban construction planning, design and construction. [0003] At present, in order to make full use of the rainwater in rainy days and reduce the number of artificial watering, the green plants on the existing roofs are planted in the open air, but in case of heavy rain or heavy rainfall In some cases, excessive water will affect the good growth of plants. There are also shelters built on green plants, but on the one hand, rainwater cannot be used after building shelters, and the frequency of artificial watering will be increased, which is troublesome and will also The p...

[0003] At present, in order to make full use of the rainwater in rainy days and reduce the number of artificial watering, the green plants on the existing roofs are planted in the open air, but in case of heavy rain or heavy rainfall In some cases, excessive water will affect the good growth of plants. There are also shelters built on green plants, but on the one hand, rainwater cannot be used after building shelters, and the frequency of artificial watering will be increased, which is troublesome and will also Plants are not exposed to direct sunlight
