[0012] Through the above scheme, it can be seen that when the rainfall is too heavy, the water outlet arranged on the inner wall surface of the placement groove will drive the water to discharge from the rainwater outlet, and then flow into the interior of the drainage board, realizing the discharge of rainwater and improving the practicality of the device.

[0013] Preferably, a rainwater outlet is provided on one side surface of the movable plate, the water outlet is communicated with the rainwater outlet, the bottom surface of the rainwater outlet is set as an inclined surface, a leakage hole is provided at the bottom of the flower pot, the leakage hole overlaps with the drainage hole, and the flower pot is movably connected to the top surface of the movable plate.

[0014] Through the above scheme, it can be seen that setting the bottom surface of the rainwater outlet as a slope can better help the rainwater to discharge downward. At the same time, the mud and debris mixed in the rainwater will also be discharged downward under the action of the slope, so that there will be no blockage, thereby improving the practicality of the device.

[0015] Technical effects and advantages of the utility model:

[0016] 1. By setting the drainage component, compared with the prior art, the drainage component is set on the top of the roof, thereby avoiding the need to open a notch on the roof surface, and prolonging the service life of the roof. The drainage pipe is installed on one side of the drainage board, so that the rainwater inside the water storage tank can be quickly discharged, and the practicality of the device is improved. At the same time, the ventilation hole opened on one side of the drainage board can ventilate the water storage tank inside the drainage board, avoiding the odor inside the drainage board due to rainwater soaking after long-term use, thereby protecting the air environment.

[0017] 2. By setting up a movable board, plant the plants in the flowerpot, and then place the flowerpot in the placement groove on the top of the movable board. When the leakage hole at the bottom of the flowerpot overlaps with the drainage hole in the placement groove, the excess rainwater in the flowerpot will flow along the leakage hole to the inside of the placement groove, and then flow to the placement rack through the drainage holes opened on the surface of the placement groove, and finally be discharged from the inside of the drainage board through the drainage pipe, thereby ensuring the discharge of rainwater without damaging the roof, thereby improving the practicality of the device.
