Expanding rain collection: Start the flip motor, which drives the flip shaft to rotate, thereby driving two worms to rotate and engage with two worm wheels. The two worm wheels drive the two rain collecting plates to flip and cooperate with the rain collecting box to collect rainwater; S2, rainwater collection: Rainwater flows into the water storage bucket through the guidance of the drainage plate. When the rainfall reaches the floating position, the floating is lifted to the upper limiting plate to push the swing frame to flip, so that the conductive sheet contacts the conductive terminal to power the electromagnet and the bimetallic sheet.

When the storage reaches a certain amount, the opening and closing valve assembly opens, and the rainwater flows down as a power source. In dry weather, the rain collecting plate can also be closed to seal the entire rain collecting box; 2. Through the arrangement of the feeding component, the stirring mechanism, the driving water wheel, the pumping component and the transmission belt pulley group, the rainwater impacts the driving water wheel during the downward flow, and the driving water wheel rotates to synchronously drive the stirring mechanism and the feeding component to rotate through the transmission belt pulley group.

Through the setting of the trigger mechanism and the opening and closing valve assembly, rainwater flows into the water storage bucket through the guidance of the drainage plate. When the rainfall reaches the floating position, the float is lifted to the upper limiting plate to push the swing frame to flip, so that the conductive sheet contacts the conductive terminal to power the electromagnet and the bimetallic strip. The bimetallic strip is heated and deformed toward one side of the swing frame to provide a downward holding force for the swing frame. The electromagnet is energized to attract the magnetic block, thereby driving the sliding rod and the sealing plate to move and open the valve plate. When the rainwater in the water storage bucket is discharged, the float slides down to the bottom. When the bimetallic strip is cooled and deformed upward, the swing frame loses the extrusion force and lifts to reset. At this time, the electromagnet is powered off, and the spring pushes the magnetic block and the sealing plate to close the valve plate. BRIEF DESCRIPTION OF THE DRAWINGS

The desert sand compaction and afforestation rainwater collection device according to claim 1, characterized in that: The trigger mechanism (8) comprises a slide rail (81) fixed to the inner side wall of the water storage bucket (13) through a bracket, a float (82) is slidably mounted on the side wall of the slide rail (81), a movable frame (83) is fixedly mounted on the top of the slide rail (81), a bimetallic strip (84) is arranged on the inner top of the movable frame (83), and a swing frame (85) is rotatably connected to the side wall of the movable frame (83) near the bimetallic strip (84), and one end of the swing frame (85) is movable. A retaining rod (86) is connected, and the retaining rod (86) is slidably matched with the float (82). The top and bottom of the retaining rod (86) are respectively provided with limiting plates (87) for limiting the sliding of the float (82). The inner side wall of the movable frame (83) is also provided with a conductive sheet (88). The bottom of the swing frame (85) is provided with a conductive terminal (89) that contacts and cooperates with the conductive sheet (88). When the conductive terminal (89) contacts the conductive sheet (88), power is supplied to the opening and closing valve assembly (2).

10. A rain collection method for a rain collection device for desert sand compaction and afforestation as claimed in any one of claims 1 to 9, characterized in that: The steps include: S1, expanding rain collection: starting the flip motor (31), the flip motor (31) drives the flip shaft (32) to rotate, thereby driving two worms (33) to rotate and engage with two worm wheels (34), and the two worm wheels (34) drive the two rain collecting plates (11) to flip and cooperate with the rain collecting box (1) to receive rainwater; S2, rainwater collection: Rainwater flows into the water storage bucket (13) through the guidance of the drainage plate (12). When the rainfall reaches the position of the float (82), the float (82) is lifted to the upper limiting plate (87) to push the swing frame (85) to flip, so that the conductive sheet (88) contacts the conductive terminal (89) to supply power to the electromagnet (25) and the bimetallic sheet (84). The bimetallic sheet (84) is heated and deformed toward one side of the swing frame (85), providing the swing frame (85) with a downward turning retention force; S3, valve plate opening and closing: the electromagnet (25) is energized to attract the magnetic block (26), thereby driving the slide rod (23) and the sealing plate (24) to move so that the valve plate (21) opens; S4, rainwater storage: rainwater is poured out from the water storage bucket (13) to impact and drive the water wheel (6) to rotate. When the water wheel (6) rotates, the discharge roller (42) and the stirring shaft (51) are driven to rotate through the transmission belt pulley group (7). When the discharge roller (42) rotates, the precipitation agent is released through the discharge circular hole (43), and at the same time, the stirring shaft (51) rotates to mix the precipitation agent evenly; S5, valve plate closed: when rainwater in the water storage bucket (13) is drained, the float (82) slides down to the bottom, and when the bimetallic strip (84) is cooled and deforms upward, the swing frame (85) loses the squeezing force and rises to reset. At this time, the electromagnet (25) is powered off, and the spring (27) pushes the magnetic block (26) and the sealing plate (24) to close the valve plate (21); S6, water extraction: the water pump (91) is started to extract upper layer clean water through the pumping ball cage (93) for use. As the amount of water decreases, the floating plate (94) drives the pumping ball cage (93) to automatically descend; S7, sealing and dustproofing: starting the flip motor (31), the flip motor (31) drives the flip shaft (32) to rotate, thereby driving the two worms (33) to rotate and mesh with the two worm wheels (34), and the two worm wheels (34) drive the two rain collecting plates (11) to flip and cover the rain collecting box (1) to close the rain collecting box (1).
