[0026] Reference Figure 5 and Figure 6 A snap-fit ​​blind hole 214 is provided on the inner wall of the connecting sliding hole 213. When the snap-fit ​​blind hole 214 is connected to the receiving groove 334, one end of the snap-fit ​​block 35 is embedded in the snap-fit ​​blind hole 214 under the action of the snap-fit ​​spring 36. At this time, the top opening of the drain hole 333 is fitted against the inner wall of the connecting sliding hole 213, and the limiting ring 34 abuts against the inner bottom wall of the planting trough 21.

The drainage channel 102 is connected to the number of return chambers 101. The bottom end of the drainage channel 102 is connected to the water storage tank 42.

[0029] Reference Figure 3 An overlapping ring 51 is provided on the inner ring wall at the top of the reflux collection tank 5. A filter grid 52 is placed in the reflux collection tank 5 and is placed on the overlapping ring 51. Several reflux filter plates 53 are connected to the vertical side wall of the mounting plate 1. The several reflux filter plates 53 are arranged in a one-to-one correspondence with several reflux chambers 101.

[0030] Reference Figure 1 , Figure 3 and Figure 4A vertically connected evaporation connection box 6 is installed at the top of the water storage tank 42. Several evaporation openings 103 are drilled through the mounting plate 1, each corresponding to a planting trough 21 and positioned above it. The evaporation openings 103 are connected to the evaporation connection box 6. A horizontal connecting rod 7 is horizontally installed above each planting trough. Several condensation rods 8 are vertically connected to the bottom of the connecting rod 7. Several guide rods 9 are parallel to each connecting rod 7, extending into and connecting to the evaporation connection box 6. The end of the guide rod 9 furthest from the connecting rod 7 is higher than the end connected to the connecting rod 7. The guide rods 9, connecting rods 7, and condensation rods 8 are all made of a metal material with high thermal conductivity. Each evaporation opening 103 is provided with a sealing sliding plate 10 on one side. The sealing sliding plate 10 slides and fits against the mounting plate 1. The mounting plate 1 is connected to a drive cylinder 11 for driving the sealing sliding plate 10 to block the evaporation opening 103.

[0031] Reference Figure 1 and Figure 2 Two support rods 12 are vertically connected to the mounting plate 1. The top ends of the two support rods 12 are rotatably connected to a water-blocking rotating plate 13. One side of the water-blocking rotating plate 13 extends above the side of the mounting plate 1 where the planting component 2 is located. A solar panel 14 is connected to the side of the rotating plate away from the support rods 12. A top support slide rod 15 is vertically and slidably connected to the top of the water storage tank 42. One end of the top support slide rod 15 located in the water storage tank 42 is connected to a top support float 16. The end of the top support slide rod 15 extending out of the water storage tank 42 is rotatably connected to a connecting slider 17. A connecting groove 131 is opened on the side of the water-blocking rotating plate 13 near the top support slide rod 15 along a direction perpendicular to the mounting plate 1. The connecting slider 17 is slidably connected in the connecting groove 131.

[0032] Reference Figure 1 and Figure 3 The green plants are planted in the planting chambers 211 of the planting trough 21. In the event of a lack of rainwater, the irrigation pump is activated, drawing water from the storage tank 42 through the irrigation manifold 44, irrigation branch pipes 45, and several irrigation heads 46 into the planting soil 24 of the planting trough 21. Excess water in the planting chambers 211 is temporarily stored in the drainage chambers 212 of the planting trough 21 through the drainage holes 221 on the baffle plate 22. At this time, the top of the drainage hole 333 of the lifting slider 33 is blocked by the inner wall of the connecting hole 213, preventing water in the drainage chambers 212 from flowing directly out of the planting trough 21. The water in the drainage chambers 212 is drawn upward into the coconut coir absorbent layer 26 by the capillary action of the rock wool absorbent strip 25, continuously moistening the planting soil 24 in the planting chambers 211 and reducing the possibility of the planting soil 24 becoming too dry. The solar panel 14 collects and converts solar energy under sunlight to store energy for other power-required components of the device.

[0033] Reference Figure 3 , Figure 5 and Figure 6 When rainfall is heavy, excess rainwater continues to flow into the drainage chamber 212 through the drainage hole 221. The drainage float 31 rises continuously as the water level in the drainage chamber 212 increases. When the limiting block 38 moves to the top of the limiting groove 332, the lifting slider 33 moves upward with the lifting rod 32. At this time, the abutting inclined surface 351 of the locking block 35 slides relative to the inner wall of the locking blind hole 214, and the locking block 35 is squeezed into the receiving groove 334. When the lifting slider 33 moves to the point where the receiving groove 334 connects with the drainage chamber 212, the locking block 35 pops out under the action of the locking spring 36 and abuts against the inner bottom wall of the planting trough 21, thus limiting the lifting slider 33. At this time, the top of the drainage hole 333 is connected to the drainage chamber 212. Excess water in the drainage chamber 212 flows out of the planting trough 21 through the drainage hole 333. As the water level drops, the positions of the drainage float 31 and the lifting slide bar 32 decrease. When the lifting slider 33 loses the tension of the lifting slide bar 32, it slides downward under the weight of the counterweight 37. The abutting inclined surface 351 of the locking block 35 slides relative to the inner wall of the connecting slide hole 213 and is squeezed into the receiving groove 334 until the limiting ring 34 abuts against the inner bottom wall of the planting trough 21. At this time, the receiving groove 334 corresponds to the locking blind hole 214, and the locking block 35 is re-embedded in the locking blind hole 214, thus achieving the positioning of the lifting slider 33. The drainage component 3 enables the timely drainage of excess water in the planting trough 21, reducing the possibility of excess water accumulating inside the planting trough 21 and causing the plants to rot from waterlogging.

[0034] Reference Figure 3 and Figure 4 Water flowing out of the planting trough 21 enters the return collection trough 5 and then enters the water storage tank 42 through the return cavity 101 and the drainage channel 102 for storage, realizing the recycling and reuse of excess water. The filter plate 52 and the return filter plate 53 perform dual multi-stage filtration on the water entering the water storage tank 42, reducing the possibility of impurities in the water clogging the pipes.

[0035] Reference Figure 2 When rainfall is excessive, the water level in the reservoir 42 rises continuously, causing the top support float 16 to move upwards. The top support slide rod 15 rises and lifts one side of the water-blocking rotating plate 13, allowing the connecting slider 17 to slide in the connecting groove 131 of the water-blocking rotating plate 13. The other side of the water-blocking rotating plate 13 shields the planting assembly 2 from rainwater, reducing the possibility of excessive rainfall causing waterlogging and root rot in the planting trough 21. When the water level in the reservoir 42 drops, the water-blocking rotating plate 13 rotates away from the planting trough 21, reducing the possibility of the water-blocking rotating plate 13 blocking sunlight and helping the plants to photosynthesize.

[0036] Reference Figure 2 and Figure 3 During the day, when temperatures are high and rainfall is low, the sliding plate 10, driven by the cylinder 11, seals the evaporation opening 103 on the mounting plate 1, preventing water evaporation from the water storage tank 42. At night, as temperatures drop, the sliding plate 10, driven by the cylinder 11, moves away from the evaporation opening 103, allowing water in the water storage tank 42 to rise and propagate upwards through the evaporation connection box 6. When the water vapor comes into contact with the highly thermally conductive guide rod 9, it condenses into water droplets. These droplets flow along the inclined guide rod 9 to the connecting crossbar 7 and drip into the planting trough 21 through several condensation rods 8, thus replenishing the plants in the planting trough 21 with water at night.

[0037] The implementation principle of a vertical greening device for building space in this embodiment is as follows: Green plants are planted in the planting cavity 211 of the planting trough 21. When rainwater is scarce, the irrigation pump is activated to irrigate the plants in the planting trough 21. Excess water enters the drainage cavity 212 of the planting trough 21 through the drainage holes 221 on the baffle plate 22 for temporary accumulation. The water in the drainage cavity 212 is drawn upward into the coconut coir absorbent layer 26 by the capillary action of the rock wool absorbent strip 25 and stored there, continuously moistening the soil in the planting cavity 211. When rainfall is heavy, the drainage float 31 rises and the lifting slider 33 moves upward. The top of the drainage hole 333 is connected to the drainage cavity 212, and excess water flows out through the drainage hole 333. The drainage component 3 reduces the possibility of excess water accumulating inside the planting trough 21, causing the plants to rot from waterlogging.

[0038] The outflowing water enters the water storage tank 42, realizing the recycling and reuse of excess water. When the rainfall is too heavy, the water level in the water storage tank 42 rises, the top support float 16 and the top support slide 15 rise and lift one side of the water-blocking rotating plate 13, while the other side of the water-blocking rotating plate 13 blocks the top of the planting component 2, reducing the possibility of excessive rainfall causing the plants in the planting trough 21 to be soaked and rot.

[0039] When the temperature is high and the rainfall is low, the water in the reservoir 42 evaporates and rises, then propagates upward through the evaporation connection box 6. When the water vapor comes into contact with the high thermal conductivity guide bar 9, the water vapor condenses into water droplets, which then drip into the planting trough 21 through several condensation bars 8, thus replenishing the water supply to the plants in the planting trough 21 at night.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
