Secondly, most existing prefabricated modules are semi-permanent structures, making subsequent replacement and maintenance complex. Finally, to meet long-term urban greening needs, owners must invest significant human and financial resources in post-construction management, creating a substantial financial burden.

[0003] In conclusion, existing vegetated modular unit technology needs further optimization to meet the requirements of efficiency, economy, and convenience. It should become an important component of urban green infrastructure, thereby improving the urban ecological environment and enhancing the quality of life for residents. Utility Model Content

[0064] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0065] Example 1

[0066] like Figures 1 to 4As shown, a prefabricated vegetation module unit includes a vegetation wall frame 1. Multiple vegetation modules 2 are mounted on the inclined groove sidewall of the vegetation wall frame 1. The vegetation wall frame 1 is equipped with multiple pairs of hooks 11, each pair of hooks 11 used to fix the vegetation module 2. The vegetation module 2, from top to bottom, has a protective layer 21, a vegetation interlayer 22, and a water supply tank 23. The protective layer 21 provides a stable growth environment for the vegetation. The vegetation interlayer 22 fixes the vegetation substrate board 221. The water supply tank 23 provides water and nutrients to the plant seeds in the vegetation substrate board 221. A permanent magnet ring 236 floats on the water surface in the water supply tank 23. The permanent magnet ring 23 controls the status of the indicator light 231 on the outside of the water supply tank 23. When there is no water in the water supply tank 23, the indicator light 231 displays the corresponding status, and a buzzer 232 starts working to indicate the need for water and nutrients.

[0067] Furthermore, the vegetation wall frame 1 is a rectangular frame structure of several dimensions, which is fixed to the surface of the construction target using anchor rods to provide a placement space for fixing the vegetation module 2; the hook 11 is used to fasten the bottom fastening hole 237 of the vegetation module 2, and plays a fixing role.

[0068] Furthermore, the vegetation module 2 is a rectangular structure of several dimensions, consisting of a protective layer 21, a vegetation interlayer 22, and a water supply chamber 23 from top to bottom.

[0069] Furthermore, the protective layer 21 is a hollow layer with a height of 15-20 mm, encapsulated on both the upper and lower sides by stainless steel wire mesh 211 with a hole diameter of 3-5 mm and a wire diameter of 0.35-1 mm. Before encapsulating the stainless steel wire mesh 211, the hollow layer is uniformly filled with gravel with a particle size of 5-10 mm. The gravel can prevent water evaporation, provide a growth environment for plant roots, and at the same time prevent the vegetation substrate in the vegetation interlayer 22 from overflowing. The protective layer is equipped with anchoring holes 212 on its surface, which can be connected to the adjacent vegetation module 2.

[0070] Furthermore, the planting interlayer 22 is a hollow interlayer with a height of 20-30 mm, used to fix and fill the planting substrate board 221. The planting substrate board 221 is an embedded plant seed gel plate, wrapped with water-absorbing porous palm fiber, and a plate-shaped material with an outer diameter matching the inner diameter of the planting interlayer 22. The planting interlayer 22 has no sidewall on one side, and the opening of the planting interlayer 22 facilitates the installation or replacement of the planting substrate board 221.

[0071] Preferably, the water supply tank is made of PVC plastic. Further, the water supply tank 23 has a height of 30-50 mm and a sealed hollow structure with a water inlet 233. The inner side of the water supply tank 23 is lined with multiple layers of multi-capillary fiber inner liner 234. The side wall of the water supply tank 23 in contact with the plant substrate 22 is provided with multiple small holes, each of which is filled with multi-capillary fiber inner liner 234, so that the multi-capillary fiber inner liner 234 is connected to the plant substrate board 221. The multi-capillary fiber inner liner 234 transfers water and nutrients to the water-absorbing palm fiber of the plant substrate board 221 through capillary action. The water-absorbing palm fiber then diffuses the water and nutrients to the plant seed gel plate. The nutrients dissolve in the water, thereby providing the plants in the plant seed gel plate with the required water and nutrients. The long side is provided with a sliding tube 235 and a permanent magnet ring 236, and an indicator light 231 and a buzzer 232 are provided on the outside. Several buckle holes 237 are provided on the bottom outer side.

[0072] Furthermore, the slide tube 235 is a smooth tube with a diameter of 5-10 mm on the surface. The slide tube 235 is made of plastic. The tube head and tube tail at both ends of the slide tube 235 are anchored parallel to the long side of the water supply tank 23, forming a "Z" shape with the top and bottom sidewalls of the water supply tank 23. The distance between the slide tube 235 and the sidewall of the water supply tank 23 is 22-30 mm. The outer side of the permanent magnet ring 236 is a smooth ring. The hollow smooth ring of the permanent magnet ring 236 is made of polystyrene multi-cavity foam. The inner side of the smooth ring is embedded with a ring-shaped permanent magnet with an outer diameter of 18 mm and a thickness of 3 mm. The permanent magnet ring 236 passes through the slide tube 235 and is always suspended on the surface of the water.

[0073] Furthermore, the indicator light 231 includes a green light 2311, a yellow light 2312, and a red light 2313. The green light 2311 corresponds to a sufficient water level in the water supply tank 23, the yellow light 2312 corresponds to a low water level, and the red light 2313 corresponds to a depleted water level. Each light has several iron plate switches connected in parallel in its internal circuit. Each iron plate switch is made of iron plate. When the iron plate in the second conductive rod 2315 contacts the first conductive rod 2314 under the action of the permanent magnet ring 236, the indicator light 231 displays the water level status in the water supply tank 23.

[0074] The working principle of the green light 2311 and its circuit will be explained as follows: Figure 4As shown, the battery is connected to the green light 2311 via a power cord. The positive and negative poles of the green light 2311 are connected to two conductive rods respectively. The second conductive rod 2315 in the green light 2311 circuit is connected to the battery. The green light 2311 is connected to the first conductive rod 2314 via a power cord. The first conductive rod 2314 is fixedly mounted on the outer wall of the water supply tank 23. The second conductive rod 2315 is placed parallel to one side of the first conductive rod 2314, and the first and second conductive rods 2314 do not contact each other. The other side of the first conductive rod 2314 is close to the slide tube 235. Several iron plate switches are connected in parallel on one side of the second conductive rod 2315. Each iron plate switch is rotatably connected to the second conductive rod 2315 via a rotating shaft. When the water level in the water supply tank 23 is low and the permanent magnet ring 236 moves away from the iron plate switches of the green light 2311, each iron plate switch in the green light 2311 circuit is disconnected from the first conductive rod 2314.

[0075] When the water level is high, the permanent magnet ring 236 approaches and attracts the iron switch in the green light 2311 circuit. The iron switch is connected to the first conductive rod 2314, which connects the battery circuit to the green light 2311, and the green light 2311 lights up.

[0076] The connection method between the two conductive rods and the iron plate switch in the yellow light 2312 circuit and the working principle of the yellow light 2312 are the same as those of the green light 2311. When water is scarce, the permanent magnet ring 236 approaches and attracts the iron plate switch in the yellow light 2312 circuit, and the yellow light 2312 lights up.

[0077] The working principle of the red light 2313 and buzzer 232 and their circuit is the same as that of the green light 2311. The battery is connected in parallel to the red light 2313 and buzzer 232 through the power line. The connection method between the two conductive rods and their iron plate switches in the circuit of the red light 2313 and buzzer 232 is the same as that of the green light 2311. When the water is depleted, the permanent magnet ring 236 approaches and attracts the iron plate switch in the circuit of the red light 2313 and buzzer 232, and the red light 2313 lights up; and the buzzer 232 starts to sound an alarm.

[0078] When the red indicator light 231 is working normally, the buzzer 232 will also sound an alarm.

[0079] When the vegetation in the vegetation module 2 dies due to environmental factors, the vegetation module 2 can be disassembled to a flat site, the dead vegetation in the vegetation module 2 can be removed, the expired vegetation substrate board 221 can be taken out from the side of the vegetation interlayer 22, and the vegetation substrate board 221 with seeds that meet environmental factors can be replaced and maintained. After the vegetation grows to the surface of the protective layer 21, the vegetation module 2 that has been maintained can be installed in its original position to achieve the effect of long-term greening of the environment.

[0080] The above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, or improvements made, such as setting multiple green lights 2311, yellow lights 2312, and red lights 2313, multiple sliding tubes 235, and multiple permanent magnet rings 23, or changing the size of the permanent magnet rings 23, or changing the circuit connection method, such as adjusting the voltage to change the circuit to series connection, etc., can achieve the same circuit working principle. In addition, the nutrients and seeds in this utility model are only for the convenience of explaining the function of the device and are not intended to limit this utility model. Everything within the spirit and principle of this utility model should be included within the protection scope of this utility model.
