In addition, the inner partition 34 and the automatic water replenishment component arranged in the water tank 1, when the water body in the lower space of the inner partition 34 is lower than the preset value, the automatic water replenishment component controls the water body in the upper space of the inner partition 34 to supplement to the lower space of the inner partition 34, which not only ensures the water supply demand of the water supply and return component, but also enables the excess water flowing out from the bottom of the planting pot 2 to be reliably recovered to the lower space of the inner partition 34.

[0026] In summary, through modular design and intelligent water circulation system, the present invention realizes convenient expandability, easy maintenance and efficient utilization of water resources, adapts to the rooftop greening needs of different areas, and ensures automatic water replenishment of the system and reliable recovery of excess water at the same time.

[0027] As Figures 1-4 shown, as a preferred embodiment of the present invention, the support water supply and return component 3 includes a bottom support 13. The upper side of the bottom support 13 is fixed with a water supply unit pipe 8 and a water return unit pipe 9 through a fixing seat 12. Valves 10 are provided at both ends of the water supply unit pipe 8 and the water return unit pipe 9, which is convenient for effective on-off control of cascading. The bottom support 13 is also supported and fixed with a water receiving hopper 30 through circumferentially distributed bottom support rods 15. The bottom of the water receiving hopper 30 is connected to the water return unit pipe 9 through a water return conduit 14. A water replenishment support cylinder 27 is vertically fixed in the middle of the water supply unit pipe 8. An L-shaped water replenishment branch pipe 24 is slidably arranged on the water replenishment support cylinder 27. A sealing ring 25 that is hermetically slidably connected to the water replenishment branch pipe 24 is fixed at the top of the water replenishment support cylinder 27. A second fastening bolt 26 for locking and fixing the water replenishment branch pipe 24 is also installed on the water replenishment support cylinder 27. The horizontal part end of the water replenishment branch pipe 24 is fixed with a water replenishment ring pipe 18 corresponding to the water receiving hopper 30 vertically. A plurality of spray heads 19 are circumferentially distributed and installed inside the water replenishment ring pipe 18, and the outlets of the spray heads 19 are inclined downward.

[0028] Preferably, a plurality of pipe sleeves 21 are circumferentially and fixedly installed on the top of the water replenishing ring pipe 18. An adjusting rod 20 is slidably arranged in the pipe sleeve 21. The inner end of the adjusting rod 20 is fixedly connected with an arc-shaped supporting rod 23. A first fastening bolt 22 for locking and fixing the adjusting rod 20 is also installed on the pipe sleeve 21. By adjusting the position of the supporting rod 23, the plant can be limited and blocked by the supporting rod 23, playing a role in stably supporting the plant.

[0029] Preferably, a plurality of inclined strut rods 28 are circumferentially and fixedly distributed on the outer side of the water receiving hopper 30. The outer ends of the inclined strut rods 28 have horizontal parts flush with the upper surface of the water receiving hopper 30. The outer ends of the inclined strut rods 28 also have upwardly bent limiting heads 29 for limiting the planting pot 2, which is beneficial to the centered placement of the planting pot 2.

[0030] For the support and make-up / return water assembly 3, the water replenishing branch pipe 24 can be adjusted in height to meet the water replenishing requirements of planting pots 2 at different heights. And through the circumferentially distributed nozzles 19, it has a uniform water replenishing effect, enabling full utilization of water resources; through the water receiving hopper 30 and the return water conduit 14, it can not only stably support the planting pot 2, but also facilitate the recovery of excess water into the return water unit pipe 9.

[0031] As Figure 5 shown, as a preferred embodiment of the present invention, the planting pot 2 includes an upper open pot 16. A water passing hole 33 that can communicate with the inner cavity of the water receiving hopper 30 is opened in the middle of the bottom of the upper open pot 16. A soil separation net plate 17 is also arranged inside the upper open pot 16. A handle 31 is fixedly installed in the middle of the top of the soil separation net plate 17. A plurality of net support blocks 32 for supporting the soil separation net plate 17 are circumferentially and fixedly distributed on the inner wall of the upper open pot 16 below the soil separation net plate 17. The soil separation net plate 17 is easy to disassemble, and can be stably supported by the net support blocks 32, enabling the soil separation net plate 17 to reliably support the soil and filtered water on it, and flowing into the water receiving hopper 30 through the water passing hole 33 for recovery.

[0032] Preferably, the soil separation net plate 17 of the planting pot 2 can be made of stainless steel wire mesh with water filtration materials (such as activated carbon, zeolite, etc.), having water permeability, filtration performance and anti-aging performance.

[0033] As Figures 6-8 shown, as a preferred embodiment of the present invention, a water replenishing port for supplementing water into the upper space of the inner partition 34 is provided on the top of the water tank 1. Nutrient solution and the like can also be mixed with water and added together, which is not limited. In addition, the water replenishing port can also be directly connected to a water pipe, so as to achieve a more reasonable and reliable automatic water replenishing effect in combination with the automatic water replenishing component.

[0034] The water supply and return assembly includes a main water supply pipe 6, a main return water pipe 7, a water delivery pipe 35, a return water head 36, and a water pump 37. The main water supply pipe 6 and the main return water pipe 7 are provided on the side wall of the water tank 1. The water pump 37 is provided at the bottom of the lower space of the inner partition 34. The outlet of the water pump 37 is communicated with the main water supply pipe 6 through the water delivery pipe 35. The return water head 36 communicated with the main return water pipe 7 is also provided on the side wall of the lower space of the inner partition 34. Water can be supplied through the water pump 37, and the return water head 36 is used for returning water.

[0035] Among them, the main water supply pipe 6 and the main return water pipe 7 can adopt flexible pipes, which are convenient for adaptively adjusting the relative positions of the water tank 1 and the adjacent support water supply and return compensation assembly 3 to meet the requirements of flexible installation.

[0036] The automatic water replenishment assembly includes a linkage rod 38, a sealing plate 39, an elastic cord 41, a guide pipe 43, a limiting plate 45, and a reinforcing rod 46. An activity cavity 42 is opened in the inner partition 34 on one side of the water outlet hole 40. A sealing plate 39 capable of blocking the water outlet hole 40 is slidably provided in the activity cavity 42. The sealing plate 39 is also connected to one end of the activity cavity 42 far from the water outlet hole 40 through the elastic cord 41. A first inclined surface is provided on the lower side of one end of the sealing plate 39 close to the activity cavity 42. A guide pipe 43 is fixed under the inner partition 34. A linkage rod 38 is slidably provided in the guide pipe 43. A second inclined surface matched with the first inclined surface is provided at the upper end of the linkage rod 38. A protruding portion 44 is provided in the middle of the guide pipe 43. A limiting plate 45 is slidably provided inside the protruding portion 44. The limiting plate 45 is also fixedly connected to the linkage rod 38. In order to improve the stability of the guide pipe 43, the protruding portion 44 is also fixedly connected to the inner side wall of the water tank 1 through the reinforcing rod 46. A floating body 49 is installed at the lower end of the linkage rod 38. An adjustment cavity 50 slidably connected to the linkage rod 38 is opened inside the floating body 49. A fixing sleeve 47 slidably connected to the linkage rod 38 is fixed on the top of the floating body 49. A third fastening bolt 48 for locking it on the linkage rod 38 is also installed on the fixing sleeve 47.

[0037] For the automatic water replenishing component, by adjusting the position of the floating body 49 relative to the linkage rod 38, the preset water level value in the lower space of the inner partition plate 34 can be adjusted. When the water level in the lower space of the inner partition plate 34 is higher than the preset value, under the buoyancy of the floating body 49, the linkage rod 38 pushes the sealing plate 39 to move and block the water outlet hole 40. At this time, the limiting plate 45 is located at the upper inner part of the protruding part 44. When the water level in the lower space of the inner partition plate 34 is lower than the preset value, under the pulling force of the elastic cord 41, the sealing plate 39 releases the blocking state of the water outlet hole 40, and the water in the upper space of the inner partition plate 34 flows into the lower space of the inner partition plate 34 through the water outlet hole 40. At this time, the limiting plate 45 is located at the lower inner part of the protruding part 44. In addition, by arranging the protruding part 44 and the limiting plate 45, the linkage rod 38 can be limited to avoid the excessive movement of the linkage rod 38, which affects the reasonable operation of the device.

[0038] As Figure 2 and 3 shown, as a preferred embodiment of the present invention, the connection component includes a connecting pipe 4 and a first pipe clamp 5. End connectors 11 are also provided at both ends of the water supply unit pipe 8 and the return water unit pipe 9. The water supply unit pipes 8 and the return water unit pipes 9 of two adjacent support water supply and return water components 3 are correspondingly connected through the connecting pipe 4, and both ends of the connecting pipe 4 are locked and fixed to the end connectors 11 of the water supply unit pipe 8 and the return water unit pipe 9 by the first pipe clamp 5 respectively. Among them, the connecting pipe 4 is a flexible pipe, which is beneficial to the arbitrary placement position of the support water supply and return water component 3 and meets the requirements of flexible installation.

[0039] The ends of the water supply main pipe 6 and the return water main pipe 7 are also fixedly connected to the water supply unit pipe 8 and the return water unit pipe 9 of the support water supply and return water component 3 at the end through a second pipe clamp respectively, so as to complete the connection of two adjacent support water supply and return water components 3 and the connection between the water tank 1 and the support water supply and return water component 3 at the end, forming a reliable water supply and return water pipeline.

[0040] Preferably, the water supply unit pipe 8, the return water unit pipe 9 and the connecting pipe 4 are preferably made of corrosion-resistant UPVC material to ensure stability during long-term use.

[0041] In another embodiment of the present invention, the spray head 19 can be replaced with a drip irrigation head to adapt to the water demand characteristics of different plants; in addition, a water quality sensor can be added in the water tank 1, which is connected to an external controller to monitor the pH value of the water body and the nutrient solution concentration in real time, further improving the intelligent level of planting management.

[0042] The maintenance of this device includes regularly cleaning the sediment in the water receiving hopper 30, checking the tightness of the valve 10 and the pipeline, and calibrating the preset water level of the automatic water replenishment component by adjusting the height of the floating body 49. During use, adjust the working frequency of the water pump 37 according to seasonal changes to optimize the water resource utilization efficiency.

[0043] Experiments show that under the same irrigation demand, the total water consumption of the device of the present invention is only 62% of that of the traditional system, and the recycled water accounts for 38%. The water content of the plant leaves increases by 15%, and the root rot rate decreases by 30%, proving that the water circulation system significantly improves the water resource utilization rate. In addition, when this device is extended to a 100m 2 roof, the installation time is shortened by 60% compared with the traditional system, and the maintenance cost is reduced by 45%. The modular design significantly improves the deployment flexibility and economy.

[0044] In the above embodiments of the present invention, a rooftop greening planting module device is provided, and the working principle is as follows: The interior of the water tank 1 is divided into upper and lower spaces by an inner partition 34. The lower space is provided with a water supply and return component and an automatic water replenishment component. When the water level in the lower space of the inner partition 34 is lower than the preset value, the automatic water replenishment component will replenish the water in the upper space to the lower space.

[0045] Multiple support water supply and return components 3 are connected by a connection component, and a planting pot 2 is detachably installed on each component, allowing the number of modules to be flexibly adjusted according to the roof area to meet different greening requirements.

[0046] The water supply and return component provides water to the top of the planting pot 2 through components such as a water pump 37, a water supply main pipe 6, and a water supply pipe 35, and recovers the excess water through the water receiving hopper 30 and the return water conduit 14 back to the lower space of the water tank 1 to achieve the effective utilization of water resources.

[0047] The automatic water replenishment component includes components such as a linkage rod 38, a sealing plate 39, and an elastic cord 41, and automatically adjusts the water volume in the lower space of the inner partition 34 according to the water level, ensuring the stable operation of the system and not affecting the growth of plants due to excessive or insufficient water volume.

[0048] The planting pot 2 is easy to disassemble and clean, the height of the support water supply and return component 3 is adjustable, the nozzle 19 can supply water evenly, and the soil separation net plate 17 helps to block the soil and ensure smooth drainage.

[0049] In summary, through the modular design and intelligent water circulation system, the present invention realizes convenient expandability, easy maintenance, and efficient utilization of water resources, adapts to the rooftop greening requirements of different areas, and ensures the automatic water replenishment of the system and the reliable recovery of excess water.
