[0038] In a specific embodiment of the present disclosure, columns 4 are provided on both sides of the platform 3, and a connecting frame 5 is fixedly connected to the top of the column 4. A canopy 6 is provided on the top of the connecting frame 5. The canopy 6 is inclined, and baffles 7 are provided on both sides of the canopy 6. A water trough is formed between the baffle 7 and the canopy 6. The lower end of the water trough is connected to a connecting pipe 19, and the connecting pipe 19 is connected to a water tank 8 provided on the canopy 6.

The filter cartridge is arranged between two filter screens 20, and a float is arranged in the filter cartridge. A detachable sliding rod is arranged on the top of the float. The top of the sliding rod extends out of the water tank 8. A protective plate is fixedly connected to the water tank 8. The switch is arranged on the protective plate. A limit plate is sleeved on the outer side of the sliding rod. The limit plate is fixedly arranged on the top of the water tank 8. When the rainwater in the water tank 8 becomes more and more, the float moves upward in the filter cartridge due to the buoyancy of the water until it contacts the sliding rod and pushes the sliding rod to move upward. After the sliding rod moves upward, it contacts the switch and triggers the switch to pump out the water in the water tank 8 for irrigation. The water tank 8 can continue to store rainwater. The setting of the limit plate prevents the sliding rod from naturally falling into the water tank 8 under the action of gravity. Automatic irrigation with rainwater is achieved by setting the sliding assembly, which is convenient for collecting rainwater for secondary utilization.
