[0031] According to the claim, the outdoor flower stand with rainwater collection and automatic irrigation function is characterized in that a guide groove is provided between the rainwater diversion outlet 302 and the arc-shaped support plate 303, which is used to guide the rainwater flow through the rainwater diversion outlet 302 and the arc-shaped support plate 303 into the bottom water storage tank 305 when there is too much rain, and to avoid outflow of water.

[0032] In another implementation of this embodiment, in actual use, in order to allow the flowers and plants on the green plant mounting frame to receive sunlight, the external protective cover 108 of the present invention is made of transparent PC endurance board, which has the advantages of good light transmittance, impact resistance and light weight.

[0033] Working principle:

[0034] The present invention is placed at a designated outdoor location according to the use requirements. When the sunlight is strong, the solar panel 6 absorbs the sunlight and stores electricity. When it rains outdoors, rainwater enters the bottom water storage tank 102 through the water inlet 109, and then passes through the leakage hole 502 on the bottom mounting plate 501 to irrigate the plants and flowers on the mounting base 304. When the rain outside is too heavy, the rainwater entering the bottom water storage tank 102 accumulates, and under the action of gravity, the threaded column 104 is driven to rotate, thereby driving the rainwater sealing cover 101 to rotate and shielding the water inlet 109 on the external protective cover 108 to prevent too much rainwater from entering the green plant mounting frame 3. Excessive rainwater causes damage to the roots of plants and flowers. Excess rainwater flows along the rainwater diversion port 302 and enters the bottom water storage tank 305 along the dark groove in the arc-shaped support plate 303. When the weather is relatively dry and there is no rain for a long time When it rains, the mechanical timer 507 is manually adjusted to adjust the corresponding watering time and time interval. The stepper motor 506 drives the gear B508 to rotate, drives the gear C509 to rotate, and then drives the connecting plate 202 to reciprocate in a straight line, and then drives the L-shaped bracket 201 to rotate 180 degrees, and drives the compression pump 207 to operate, continuously supplying water to water the flowers and plants placed on the mounting base 304. When the amount of water in the top water tank 301 decreases, and the bottom end of the buoyancy plate 306 triggers the water pump to turn on the switch 307, the water pump 4 starts to work and pumps the accumulated water in the bottom water tank 305 into the top water tank 301. The buoyancy of the buoyancy plate 306 increases with the increase of water. When the buoyancy plate 306 rises to a certain height, it triggers the control switch at the top of the top water tank 301 to turn off the operation of the water pump 4.
