DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1: This example aims to solve the problem that in the existing technology, most of the drainage designs for roof plants adopt the common drainage method. When it rains, the rainwater is discharged without timely storage. This requires the owner to water the plants in time, which makes maintenance more troublesome. Please refer to Figure 1-Figure 5 A roof greening drainage device includes a planting block 120, which is installed on the side of a first module 110. The first module 110 includes a matrix layer 231, an exhaust hole 400 is opened in the middle of the matrix layer 231, a filter plate 232 is installed at the bottom of the matrix layer 231, a flow channel 220 is provided at the bottom of the filter plate 232, and a water storage component 390 is provided on the side of the flow channel 220. The side of the first module 110 is fixedly connected to a connecting block 150, and the side of the connecting block 150 is snap-connected to the second module 190.

[0024] A fixing block 180 is fixedly connected to the side of the connecting block 150, a slot 160 is provided on one side of the connecting block 150, and a locking slot 170 is provided on the other side of the connecting block 150. A first locking block 200 is fixedly installed on one side of the second module 190, and a second locking block 210 is fixedly connected to the other side of the second module 190. The first locking block 200 is locked and connected to the slot 160, and the second locking block 210 is locked and connected to the locking slot 170. The first module 110 and the second module 190 are locked and connected to the bottom with a locking block 130. The side of the locking block 130 is fixedly connected to the limiting block 140, and the limiting block 140 is clamped by the first module 110 and the second module 190.

[0025] After the green vegetation is planted, if there is heavy rain, the heavy rain will first hit the first module 110 and the second module 190. Since the bottom of the planting block 120 is the matrix layer 231, after the rain, the matrix layer 231 will first absorb part of the rainwater, and then the rainwater will flow through the filter plate 232, and the matrix will be filtered by the filter plate 232 to prevent the matrix from being lost due to the erosion of heavy rain. After the rainwater flows into the flow channel 220, since most roofs are inclined, the rainwater will flow to a lower place, so that part of the rainwater will flow into the collection box 230.

[0026] When rainwater flows in, if the rainwater in the collection box 230 accumulates to a certain level, the float 270 will block the flow port at the flow channel, and then the subsequent rainwater will flow through the flow channel 220 and then be discharged through the drain pipe 380. When the substrate is relatively wet, it can be dissipated through the exhaust hole 400 to avoid the problem of plant root rot caused by the high humidity of the substrate as much as possible. During the water storage process, the rainwater will squeeze the limit plate 280. At this time, the limit plate 280 will push the first slider 340 and the second slider 290 to slide. During the sliding process of the first slider 340 and the second slider 290, the connecting spring 330 will be squeezed. When it is sunny, the rainwater in the collection box 230 will be absorbed by the substrate. During the absorption process, the water in the collection box 230 becomes less. At this time, the limit plate 280 will be pushed to reset by the connecting spring 330.

[0027] In this embodiment: through the setting of the collection box 230 and the connecting pipe 240 in the water storage component 390, water can be effectively collected and guided to prevent water accumulation on the roof. Through the setting of the float 270 at the bottom of the circulation pipe 260 and the limit plate 280 in the water storage tank 250, the water level can be automatically adjusted to prevent too much or too little water in the collection box 230. Through the mechanical linkage of the rotating rod 360, the rotating shaft 300 and the slider, the frequency and cost of manual maintenance can be reduced. The setting of the exhaust hole 400 in the middle of the matrix layer 231 and the filter plate 232 at the bottom helps to discharge excess water and prevent plant roots from being soaked in water. At the same time, the filter plate 232 can prevent soil loss. Through the setting of the connecting block 150 and the fixing block 180, and the snap connection between the first module 110 and the second module 190, the structural stability of the entire device is enhanced, so that it can withstand the weight of the roof and the influence of the external environment.

[0028] Example 2: This example is intended to solve the problem of inconvenient water storage. This example is an improvement made on the basis of Example 1. For details, please refer to Figure 1-Figure 5 The water storage assembly 390 includes a collection box 230 installed in the middle of the flow channel 220. A connecting pipe 240 is fixedly installed in the middle of the collection box 230 and the bottom of the filter plate 232. The middle of the connecting pipe 240 is connected to the flow pipe 260.

[0029] A float 270 is provided at the bottom of the circulation pipe 260, a water storage tank 250 is opened in the middle of the collection box 230, a drainage pipe 380 is connected to the bottom of the collection box 230, a limit plate 280 is slidably installed in the middle of the water storage tank 250, and a first slider 340 is slidably connected to the bottom of the limit plate 280. A rotating shaft 350 is installed in the middle of the first slider 340, and a rotating rod 360 is hinged on the side of the rotating shaft 350. A connecting spring 330 is connected to the side of the first slider 340.

[0030] A fixed shaft 370 is fixedly installed in the middle of the rotating rod 360, a rotating rod 310 is hinged on the side of the fixed shaft 370, a rotating shaft 300 is hinged on the end of the rotating rod 310, the rotating shaft 300 is fixedly installed in the middle of the second slider 290, the second slider 290 is slidably connected to the bottom of the water tank 250, two first sliders 340 and two second sliders 290 are symmetrically arranged with the fixed shaft 370 as the center, and the sides of the first slider 340 and the second slider 290 are both inserted with extrusion rods 320.

[0031] In this embodiment: through the setting of the water storage component 390, the drainage system is made more efficient and the risk of water accumulation on the roof is reduced; through the linkage setting of the limit plate 280 and the slider, the water level adjustment is made more sensitive and reliable; through the symmetrical setting of the rotating shaft 350 and the slider, the balance and stability of the water level adjustment are improved; through the plug-in setting of the extrusion rod 320, the stability and durability of the slider are further enhanced.
