Technical Field

[0001] The present invention belongs to the technical field of landscaping devices, and particularly relates to a green plant wall with an irrigation system. Background Art

[0002] A green plant wall (also known as a vertical garden or living wall) refers to a vertical greening space formed by planting plants on the wall surface of a building through a special support structure and a plant growth medium. This design is not only beautiful but also can improve the urban environment, enhance the energy efficiency and air quality of the building.

[0003] Existing green plant walls generally include a support structure, planting trays, an irrigation system, etc.; the support structure is usually supported by aluminum alloy or stainless steel materials, and rows of planting trays for plant growth are arranged on its surface from top to bottom. Vent holes are also provided at the bottom of the planting trays; the irrigation system includes a main water supply pipe and a plurality of branch pipes connected to the main water supply pipe, and water is distributed into each planting tray on each layer through the main water supply pipe and the branch pipes.

[0004] When this kind of green plant wall is irrigated, water is supplied to the plants in each planting tray on each layer through the main water supply pipe and the branch pipes. Because vent holes are provided at the bottom of each planting tray, the excess water in the upper planting tray easily flows into the lower planting tray during watering. Finally, the plants in the lower planting tray are in an environment of water oversaturation for a long time. At the same time, since the water left by the upper plants may contain dissolved fertilizers, pesticide residues or other impurities, these substances and the water oversaturated environment will have an adverse impact on the growth of the lower plants. Summary of the Invention

[0005] The purpose of the present invention is to provide a green plant wall with an irrigation system, which avoids the problem that the excess water in the upper planting tray of the existing green plant wall flows into the lower planting tray during watering, resulting in water saturation in the lower planting tray.

After the liquid level gauge measures the amount of water entering the functional cavity and transmits it to the control unit, the control unit can accurately calculate the water demand of each layer of planting trays next time.

[0018] A plugging unit for controlling the water outlet in batches is further arranged in the water storage tank. Through the plugging unit, watering can be carried out in sequence according to the water demand of each layer of planting trays, avoiding overwatering.

[0027] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and cannot be used to limit the protection scope of the present invention.

[0028] A green plant wall (also known as a vertical garden or living wall) refers to a vertical greening space formed by planting plants on the wall surface of a building through a special support structure and a plant growth medium. This design is not only beautiful but also can improve the urban environment, enhance the energy efficiency and air quality of buildings.

[0029] Existing green plant walls generally include a support structure, planting trays, an irrigation system, etc.; the support structure is usually supported by aluminum alloy or stainless steel materials, and rows of planting trays for plant growth are arranged on its surface from top to bottom. Ventilation holes are also provided at the bottom of the planting trays; the irrigation system includes a main water supply pipe and a plurality of branch pipes connected to the main water supply pipe. Water is distributed into each planting tray on each layer through the main water supply pipe and the branch pipes.

[0030] When this kind of green plant wall is irrigated, water is poured on the plants in each layer of planting trays through the main water supply pipe and the branch pipes. Since ventilation holes are provided at the bottom of each planting tray, the excess water in the upper planting tray easily flows to the lower planting tray during watering. Finally, the plants in the lower planting tray are in an environment of water supersaturation for a long time. At the same time, because the water left by the upper plants may contain dissolved fertilizers, pesticide residues or other impurities, these substances and the water supersaturated environment will have an adverse impact on the growth of the lower plants.

[0031] A green plant wall with an irrigation system disclosed by the present invention, as Figures 1-3 shown, includes a frame 1. A plurality of layers of planting trays 3 are arranged on one side of the frame 1. A control unit is arranged at the top of the frame 1. It further includes: a water storage tank 2, a blocking unit, an irrigation unit, a plurality of water receiving trays, a plurality of humidity sensors and a one-way reflux unit; wherein the water storage tank 2 is arranged at the top of the frame 1, and a plurality of water outlets are provided on its bottom surface; each group of irrigation units includes a main pipe 6, an intermediate water tank 7 and a branch pipe 8 that are connected in sequence. The intermediate water tank 7 is arranged corresponding to each layer of planting tray 3. One end of the main pipe 6 away from the intermediate water tank 7 is communicated with one of the water outlets, and one end of the branch pipe 8 away from the intermediate water tank 7 is communicated with a corresponding planting tray 3; a plurality of water receiving trays 9 are respectively arranged at the bottom of each planting tray 3; the one-way reflux unit is arranged between the intermediate water tank 7 and the water receiving tray 9. Through the one-way reflux unit, the water in the water receiving tray 9 can flow into the corresponding planting tray 3. Through the correspondingly arranged water receiving tray 9 and the intermediate water tank 7, the water falling from each planting tray 3 can be refluxed for the next irrigation, thereby avoiding flowing into the lower planting tray 3; a plurality of humidity sensors are respectively arranged in each planting tray 3, and the humidity sensors are respectively connected to each control unit. The humidity sensors are used to detect the humidity of each planting tray, so as to realize precise irrigation.

[0032] Therefore, the present invention discloses a green plant wall, which, when watering, irrigates each planting tray on each layer respectively through an irrigation unit composed of a main pipeline 6, an intermediate water tank 7 and a branch pipeline 8. When irrigating, the water falling from the air holes at the bottom of each planting tray 3 will be caught by a water receiving tray 9, and the water falling into the water receiving tray 9 will also flow back to the intermediate water tank synchronously through a one-way reflux unit as backup water for the lower-side irrigation. When the water in the water receiving tray flows back to the intermediate water tank, it can also prevent the water in the water receiving tray 9 from overflowing and falling into the lower-layer planting tray. At the same time, the water in the water receiving tray 9 flowing back to the intermediate water tank is used for the next irrigation of the plants on this layer, so as to avoid the water leaking from the upper layer falling into the lower layer and affecting the normal growth of the lower-layer plants due to the presence of fertilizer, pesticide residues or other impurities. In summary, the green plant wall of the present invention can effectively prevent the water in the upper planting tray from falling into the lower planting tray, so it will not cause water supersaturation in the lower planting tray, and at the same time, it can also prevent the fertilizer, pesticide residues or other impurities in the water left by the upper plants from affecting the normal growth of the lower-layer plants.

[0033] And before each irrigation, the humidity sensors arranged in each planting tray 3 on each layer can detect the soil humidity in each planting tray 3. Then, the humidity sensors transmit the detected humidity information to the control unit. After that, the control unit calculates the water demand in each planting tray according to the humidity information detected by each humidity sensor. Finally, the control unit controls the rotating disk 4 to rotate. When the rotating disk 4 rotates, the circular holes on one of the blocking strips 5 arranged thereon correspond to each opening in turn, so that the corresponding main pipeline 6 is connected, thus realizing accurate irrigation of each planting tray.

[0034] In order to enable the water in the water receiving tray 9 to flow back to the intermediate water tank 7 without being affected by the water flow in the intermediate water tank 7, the one-way reflux unit disclosed in this embodiment includes a partition plate 10, a water diversion plate 13, a water diversion pipe 14 and a one-way valve. The partition plate 10 is horizontally arranged in the intermediate water tank 7 and is slidably connected to the inner wall of the intermediate water tank 7. The partition plate 10 can slide along the vertical direction. The partition plate 10 divides the intermediate water tank 7 into an upper water storage cavity 11 and a lower functional cavity 12. The water diversion plate 13 is obliquely arranged in the water receiving tray 9. The lower end of the water diversion plate 13 passes through the side walls of the water receiving tray 9 and the functional cavity 12 in turn and extends into the functional cavity 12. The water diversion pipe 14 is vertically arranged on the partition plate 10 and connects the functional cavity 12 with the water storage cavity 11. The one-way valve is connected to the water diversion pipe 14. Therefore, the water falling into the water receiving tray 9 falls on the inclined water diversion plate 13, and then flows back into the functional cavity 12 through the water diversion plate 13. Finally, under the action of the water diversion pipe 14 and the one-way valve, it flows into the water storage cavity 11 of the intermediate water tank 7 for the next irrigation.

[0035] After watering for a period of time, the water in each planting tray 6 has basically leaked out. In order to prevent the water receiving tray 9 from affecting the growth of the plants on the lower side, the water receiving tray needs to slide to the inner side of the functional cavity each time after water collection. Therefore, a rectangular groove is provided on the side wall of the functional cavity 12 disclosed in this embodiment. The water receiving tray 9 passes through the rectangular groove and is slidably connected to the functional cavity 12, and the water receiving tray 9 can slide along the horizontal direction.

[0036] And when water collection is needed, in order to make the water receiving tray 9 slide out automatically for water collection, a first wedge-shaped block 15 is provided at the bottom of the partition plate 10 disclosed in this embodiment, and a second wedge-shaped block 16 corresponding to the first wedge-shaped block 15 is provided on the inner side wall of the water receiving tray 9. The inclined surfaces on the first wedge-shaped block 15 and the second wedge-shaped block 16 are arranged correspondingly. In this way, each time when watering and irrigation are carried out and the water in the water storage cavity on each intermediate water tank 7 gradually increases, under the action of gravity, the partition plate 10 gradually moves downward. Therefore, the first wedge-shaped block 15 provided on the lower side of the partition plate 10 also moves downward. After that, the first wedge-shaped block 15 presses the second wedge-shaped block 16, and the second wedge-shaped block 16 drives the water receiving tray 9 to slide outwards. Therefore, the water receiving tray 9 can slide out automatically for water collection while watering.

[0037] In order to ensure the smooth sliding of the water receiving tray 9, a horizontal support plate is provided at the opening of the functional cavity 12 disclosed in this embodiment. The water receiving tray 9 is slidably connected to the support plate. A first motor 17 is also provided on the outer side wall of the intermediate water tank 7. The output shaft of the first motor 17 is horizontally arranged and a first gear 18 is provided thereon. A rack 19 meshing with the first gear 18 is provided at the bottom of the water receiving tray 9. The first motor 17 is connected to the control unit. After the water leakage is completed, the control unit controls the first motor 17 to work so as to drive the water receiving tray to slide into the functional cavity, so that the upper water receiving tray 9 will not affect the growth of the plants in the lower planting tray.

[0038] Further, in order to remove the impurities in the water in the water receiving tray 9, a filter plate perpendicular to and vertically upward is also provided at the lower end of the water diversion plate 13. The filter plate can filter the impurities in the water in the water receiving tray 9 to ensure that there are no impurities in the water entering the functional cavity. At the same time, in order to ensure that the water can be normally irrigated subsequently, an ultraviolet lamp for disinfecting the water is also provided at the bottom of the partition plate 10.

[0039] Further, a liquid level gauge is provided in the functional cavity 12 disclosed in this embodiment. The liquid level gauge is connected to the control unit. When the control unit calculates the water demand in each layer of planting pots, it will first remove the water flow measured by each liquid level gauge to avoid over-irrigation. Therefore, after the liquid level gauge measures the amount of water entering the functional cavity and transmits it to the control unit, the control unit can accurately calculate the water demand in each layer of planting trays 3 next time.

[0040] A second motor 20 is provided on the inner bottom surface of the water storage tank 2. The output shaft of the second motor 20 is vertically upward, and the rotating disk 4 is provided on the output shaft of the second motor 20. The second motor 20 is connected to the control unit.

[0041] Since the water requirements of the plants in each planting tray are different, in order to achieve precise irrigation of each planting tray and avoid a large amount of water flowing into the water receiving tray, a plugging unit for controlling the water discharge in batches is also provided in the water storage tank 2. The plugging unit can water according to the water requirements in each planting tray 3 in sequence, avoiding overwatering.

[0042] Further, the plugging unit disclosed in this embodiment includes a rotating disk 4 and a plurality of plugging strips 5. The number of plugging strips 5 is one more than the number of water outlets. The rotating disk 4 is rotatably provided on the inner bottom surface of the water storage tank 2. The plurality of plugging strips 5 are uniformly arranged along the circumferential direction of the rotating disk 4. A circular hole corresponding to the water outlet is provided on one of the plugging strips 5. During irrigation, each planting tray 3 is irrigated through an irrigation unit composed of a main pipeline 6, an intermediate water tank 7, and a branch pipeline 8. During irrigation, since a plugging unit is provided in the water storage tank 2, when irrigation starts, only one plugging strip 5 with a water outlet circular hole on the plugging unit can communicate with one of the water outlets. Since only one irrigation path composed of a main pipeline 6, an intermediate water tank 7, and a branch pipeline 8 can intake water and irrigate, the green plant wall can be irrigated separately from top to bottom during irrigation. In this way, when irrigating each layer separately, it can also be irrigated according to the water shortage situation in each planting tray 3. At the same time, the water leaked from each planting tray will flow back to the intermediate water tank for the next irrigation, avoiding the water from the upper layer falling into the lower layer and causing waterlogging in the lower planting tray. Therefore, precise irrigation can be achieved to ensure the normal growth of the green plants on each layer.

[0043] In order to achieve automatic control of irrigation, a second motor 20 is provided on the inner bottom surface of the water storage tank 2 disclosed in this embodiment. The output shaft of the second motor 20 is vertically upward, and the rotating disk 4 is provided on the output shaft of the second motor 20. The second motor 20 is connected to the control unit. Therefore, when the second motor 20 works, it can drive the rotating disk 4 to rotate. In this way, according to the water shortage situation in each planting tray 3, the control unit can control the second motor 20 to irrigate and achieve control of the irrigation duration of each planting tray 3.

[0044] In summary, for the green plant wall with an irrigation system disclosed in the invention, each planting tray is irrigated through an irrigation unit composed of a main pipeline, an intermediate water tank and branch pipelines. Before each irrigation, the humidity sensors arranged in the planting trays on each layer can detect the soil humidity in each planting tray. Then, the humidity sensors transmit the detected humidity information to the control unit. After that, the control unit calculates the water demand in each planting tray according to the humidity information detected by each humidity sensor. At the same time, when calculating the flow rate of each water outlet, the loop water flow measured by the liquid level gauge will be subtracted from the water demand to avoid over-irrigation. Finally, after the water output of each water outlet is determined, the control unit controls the rotating disk to rotate. When the rotating disk rotates, the round holes on a sealing strip arranged on it correspond to each opening in turn, so that the corresponding main pipeline is connected. Therefore, accurate irrigation of each planting tray can be realized. And when irrigating, the water falling from the air holes at the bottom of each planting tray 3 will be caught by the water receiving tray 9, and the water falling into the water receiving tray 9 will also flow back to the intermediate water tank through the one-way reflux unit synchronously as the standby water for the lower-side irrigation. When the water in the water receiving tray flows back to the intermediate water tank, it can also prevent the water in the water receiving tray 9 from overflowing and falling into the lower-layer planting tray. In summary, the green plant wall of the present invention can effectively prevent the water in the upper-layer planting tray from falling into the lower-layer planting tray, so it will not cause water oversaturation in the lower-layer planting tray. At the same time, it can also prevent the fertilizer, pesticide residues or other impurities in the water left by the upper-layer plants from affecting the normal growth of the lower-layer plants.

[0045] The above-described embodiments are only the preferred specific embodiments of the present invention, and the protection scope of the present invention is not limited thereto. Any simple changes or equivalent replacements of the technical solutions that can be obtained by those skilled in the art within the technical scope disclosed by the present invention shall fall within the protection scope of the present invention.
