Description

Technical Field

[0001] This invention relates to the field of automatic irrigation device technology, and more specifically, to an automatic soil moisture compensation device and construction method for planting on staggered balconies. Background Technology

[0002] With the increasing demand for improved housing among residents, iconic buildings such as fourth-generation residences have emerged, and balcony gardens have become a design highlight of many high-quality homes. Split-level balcony gardens require sophisticated planting and irrigation maintenance, and commonly employ two irrigation methods: manual watering and intelligent monitoring irrigation. A typical balcony garden is approximately 10 square meters in size. 2 Manual watering is time-consuming and labor-intensive, plant care relies entirely on experience, and soil moisture cannot be precisely controlled, making it unfriendly to residents without gardening experience or interest. Intelligent monitoring irrigation uses irrigation pipes and humidity sensors installed at the plant roots to detect soil moisture and automatically replenish water. However, due to the placement of humidity sensors and the lag in water penetration from the soil, uneven or excessive soil moisture can occur in certain areas. Currently, no reasonable solution has been proposed to address the problems in these technologies. Summary of the Invention

[0008] The water tank supply system is used to supply water to the planting area of ​​the staggered balcony garden. The soil moisture monitoring and control system is used to monitor soil moisture and regulate the operation of each component. The water storage module is fully covered on the bottom surface of the garden planting area and has grooves in some areas.

[0014] Furthermore, the humidity sensor uses a soil moisture transmitter with a detection range of 0-100% VOL, a resolution of 0.1%, a signal transmission mode of RS485, and a voltage of 5-24VDC.

[0015] Furthermore, the porous irrigation pipe is a plastic flexible tube with a diameter of 10mm, and a circular hole with a diameter of 3mm on its surface. The burial depth is 300mm, or the burial depth can be adjusted according to the growth depth of the plant roots.

[0016] Furthermore, the tubular water-absorbing module is a vertical plastic tube with a diameter of 10mm, a round hole with a diameter of 3mm on its surface, a sealed top, and a lower end connected to the cuboid water-absorbing module, and the water-absorbing material inside the tubular water-absorbing module is in contact with the water-absorbing material inside the cuboid water-absorbing module.

[0017] The rectangular water-absorbing module is a square container with dimensions of 500×200×100mm, with an open bottom that is in contact with the water storage module;

[0018] The electric actuator includes an electric push rod and a baffle. The output end of the electric push rod is connected to the baffle. The push rod has a thrust of 400mm. The baffle has dimensions of 200×100mm, which is the same as the cross-sectional dimensions of the cuboid water absorption module.

[0019] Furthermore, the water storage module has a depth of 150mm, a groove depth of 100mm, a water line depth of 50mm, and a side drain with a diameter of 100mm is provided on the side wall of the water storage module.

[0020] Furthermore, the rectangular water-absorbing module is placed between the water storage module and the upper nutrient soil.

[0021] A construction method for an automatic soil moisture compensation device for planting on a staggered balcony, the construction method comprising the following steps:

[0022] Step 1: Install the water tank supply system. Fix the height-adjustable bracket to a suitable position on the staggered balcony. Install the irrigation water tank on the height-adjustable bracket. Connect one end of the metal inlet hose to the DN15 diameter PPR water supply pipe on the balcony through the water supply angle valve, and connect the other end to the irrigation water supply float valve. Then connect the irrigation water supply float valve to the irrigation water tank. Connect one end of the plastic outlet hose to the irrigation water tank, and connect the other end to the perforated irrigation water pipe.

Test the operating status of each component to ensure that the humidity monitoring, water replenishment, and drainage functions are normal.

[0026] Furthermore, during system operation, when soil moisture is less than a predetermined value, the irrigation tank supplies water to the porous irrigation pipe through a plastic outlet hose. Simultaneously, the tubular and cuboid water-absorbing modules of the automatic micro-adjustment module absorb water from the storage module and replenish the soil. When soil moisture is greater than a predetermined value, the irrigation tank stops supplying water to the porous irrigation pipe. The humidity sensor transmits the detection data to the humidity monitoring controller, which controls the electric propeller to repeatedly compress the cuboid water-absorbing module, discharging water to the storage module. At the same time, the soil itself releases water into the storage module. When the water depth in the storage module exceeds 100mm, the water is discharged through the side drain.

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0036] Example 1

[0037] from Figure 1-3 As can be seen, the automatic soil moisture compensation device for planting on a staggered balcony in this embodiment includes a garden planting area 17, a water tank supply system, a soil moisture monitoring and control system, a water storage module 11, and an automatic micro-adjustment module.

[0038] The water tank supply system is used to supply water to the planting area 17 of the staggered balcony garden. The soil moisture monitoring and control system is used to monitor soil moisture and regulate the operation of each component. The water storage module 11 is fully covered on the bottom surface of the garden planting area 17 and has grooves in some areas. The lower part of the automatic micro-adjustment module is placed in the groove of the water storage module 11 to make micro-adjustments to the soil moisture. A side drain 10 is provided on the side wall of the water storage module 11 to drain excess water in the water storage module 11. The upper nutrient soil 16 is laid on the upper side of the water storage module 11.

[0039] The output end of the water tank supply system is connected to a porous irrigation pipe 13, which is laid in the upper nutrient soil 16 of the garden planting area 17.

[0040] The soil moisture monitoring and control system includes a moisture sensor 9, a moisture monitoring controller 7, and an electric thruster 12. The moisture sensor 9 is connected to the moisture monitoring controller 7 via an RS485 data cable 6, and the moisture monitoring controller 7 is connected to the electric thruster 12 via a power cable 8. The moisture sensor 9 monitors soil moisture, assists in determining soil moisture, and adjusts the water tank height. The dynamic adjustment module finely adjusts the soil moisture in the garden to maintain it within a specified range.

[0041] The automatic micro-adjustment module includes a tubular water absorption module 15 and a cuboid water absorption module 14. The bottom of the tubular water absorption module 15 is in contact with the cuboid water absorption module 14, and one end of the cuboid water absorption module 14 is in contact with the electric propeller 12.

[0042] The water tank supply system includes an irrigation water tank 3, a height-adjustable bracket 4, a metal inlet hose 1, an irrigation water supply float valve 2, and a plastic outlet hose 5. The irrigation water tank 3 is fixed on the height-adjustable bracket 4. One end of the metal inlet hose 1 is connected to the balcony water supply pipe, and the other end of the metal inlet hose 1 is connected to the irrigation water tank 3 through the irrigation water supply float valve 2. One end of the plastic outlet hose 5 is connected to the irrigation water tank 3, and the other end of the plastic outlet hose 5 is connected to a multi-hole irrigation water pipe 13.

[0043] Irrigation water tank 3 stores irrigation water. Irrigation water tank 3 is a cubic stainless steel water tank of 0.3×0.3×0.3m³. Height-adjustable bracket 4 is a galvanized steel bracket with an adjustable height of 50-500mm. The float ball of irrigation water supply float valve 2 is used to control the water depth of irrigation water tank 3 to 150mm. The length of plastic outlet hose 5 is not less than 1m.

[0044] The humidity sensor 9 uses a soil moisture transmitter with a detection range of 0-100% VOL, a resolution of 0.1%, a signal transmission mode of RS485, and a voltage of 5-24VDC.

[0045] The porous irrigation pipe 13 is a plastic flexible tube with a diameter of 10mm and a circular hole with a diameter of 3mm on its surface. The burial depth is 300mm, or the burial depth can be adjusted according to the growth depth of the plant roots.

[0046] The tubular water-absorbing module 15 is a vertical plastic tube with a diameter of 10mm and a 3mm diameter circular hole on its surface. The top is sealed, and the bottom end connects to the cuboid water-absorbing module 14. The water-absorbing material inside the tubular water-absorbing module 15 is in contact with the water-absorbing material inside the cuboid water-absorbing module 14; a micro-water supply path is formed through capillary absorption.

[0047] The rectangular water absorption module 14 is a square container with dimensions of 500×200×100mm, with an open bottom that is in contact with the water storage module 11;

[0048] The electric pusher 12 includes an electric push rod and a baffle. The output end of the electric push rod is connected to the baffle. The push rod has a push length of 400mm. The baffle has a size of 200×100mm, which is the same as the cross-sectional size of the cuboid water absorption module 14.

[0049] The cuboid water-absorbing module 14 and the electric propeller 12 together form a micro-drainage system;

[0050] The water storage module 11 has a depth of 150mm, a groove depth of 100mm, a water line depth of 50mm inside the water storage module 11, and a side drain 10 with a diameter of 100mm is provided on the side wall of the water storage module 11.

[0051] The rectangular water-absorbing module 14 is placed between the water storage module 11 and the upper nutrient soil 16.

[0052] The height of the irrigation tank 3 is adjusted according to the soil moisture and the predetermined soil moisture value monitored by the humidity monitoring controller 7. When the soil moisture is greater than the predetermined soil moisture value, the water tank will no longer supply water through the perforated irrigation pipe 13, thus forming a dynamic balance of water supply to the water tank. The soil moisture is determined according to the needs of plant growth. The height of the irrigation tank 3 is monitored and adjusted according to the soil moisture after the system device is installed.

[0053] The porous irrigation pipe 13 supplies water to the soil. When the soil moisture reaches the predetermined value, the irrigation water tank 3 stops supplying water. When the external environment supplies additional water to the upper nutrient soil 16 and the soil moisture exceeds the predetermined value, the cuboid water absorption module 14 and the tubular water absorption module 15 will absorb the water in the soil.

[0054] When the soil moisture is high, the cuboid water absorption module 14 and the tubular water absorption module 15 stop absorbing water after they are saturated. The humidity sensor 9 transmits the detection data to the humidity monitoring controller 7 via the RS485 data line 6. After the humidity monitoring controller 7 judges the data, it transmits the signal to the electric propeller 12. The electric propeller 12 repeatedly compresses the cuboid water absorption module 14 to discharge the water into the water storage module 11. The cuboid water absorption module 14 absorbs water from the upper nutrient soil 16, reducing the humidity of the upper nutrient soil 16.

[0055] When the upper nutrient soil 16 is too large, the cuboid water-absorbing module 14 and the tubular water-absorbing module 15 will stop absorbing water after they are saturated. The water in the soil will be discharged to the water storage module 11 in two ways: the electric propeller 12 will repeatedly compress the cuboid water-absorbing module 14 to absorb the water in the soil, and the soil will drain water into the water storage module 11 using its own water separation function; when the water depth in the water storage module 11 exceeds 100mm, it will be discharged through the side drain 10 on the side wall of the garden.

[0056] The tubular water-absorbing module 15 extends into the upper nutrient soil 16 and can absorb water from the soil; the tubular water-absorbing module 15 and the cuboid water-absorbing module 14 are in contact vertically, and water is absorbed from the water storage module 11 through the cuboid water-absorbing module 14 by capillary action.

[0057] The rectangular water-absorbing module 14 and the tubular water-absorbing module 15 are integrated. They can absorb water from the upper nutrient soil 16 and also absorb water from the water storage module 11. Under the repeated compression action of the electric propeller 12, the water is finally discharged to the water storage module 11.

[0058] Example 2

[0059] from Figure 1-3 As can be seen, the construction method of the automatic soil moisture compensation device for planting on a staggered balcony in this embodiment includes the following steps:

[0060] Step 1: Install the water tank supply system. Fix the height-adjustable bracket 4 to a suitable position on the staggered balcony. Install the irrigation water tank 3 on the height-adjustable bracket 4. Connect one end of the metal inlet hose 1 to the DN15 diameter PPR water supply pipe of the balcony through the water supply angle valve, and connect the other end to the irrigation water supply float valve 2. Then connect the irrigation water supply float valve 2 to the irrigation water tank 3. Connect one end of the plastic outlet hose 5 to the irrigation water tank 3, and connect the other end to the perforated irrigation water pipe 13. Lay the perforated irrigation water pipe 13 in the upper nutrient soil 16 of the garden planting area 17.

[0061] Step 2: Install the soil moisture monitoring and control system and the automatic micro-adjustment module. Bury the moisture sensor 9 in the upper nutrient soil 16. Connect the moisture sensor 9 to the moisture monitoring controller 7 through the RS485 data cable 6. Connect the moisture monitoring controller 7 to the electric propeller 12 through the power cable 8. After assembling the tubular water absorption module 15 and the cuboid water absorption module 14, connect the cuboid water absorption module 14 to the propulsion plate of the electric propeller 12. Then place the lower part of the automatic micro-adjustment module in the groove of the water storage module 11.

[0062] Step 3: Install the water storage module 11 and the side drain 10. Cover the bottom of the garden with the water storage module 11 and make holes in the side wall of the water storage module 11 to install the side drain 10.

[0063] Step 4: System debugging and operation. Start the humidity monitoring controller 7, adjust the height of the height-adjustable bracket 4 according to the preset soil moisture value required for plant growth, so that the water outlet pipe of the irrigation water tank 3 and the porous irrigation water pipe 13 form a dynamic pressure balance, test the operating status of each component, and ensure that the humidity monitoring, water replenishment and drainage functions are normal.

[0064] During system operation, when soil moisture is less than a predetermined value, irrigation tank 3 supplies water to porous irrigation pipe 13 through plastic outlet hose 5. At the same time, tubular water absorption module 15 and cuboid water absorption module 14 of automatic micro-adjustment module absorb water from water storage module 11 and replenish the soil. When soil moisture is greater than a predetermined value, irrigation tank 3 stops supplying water to porous irrigation pipe 13. Humidity sensor 9 transmits detection data to humidity monitoring controller 7. Humidity monitoring controller 7 controls electric propeller 12 to repeatedly compress cuboid water absorption module 14, discharging water to water storage module 11. At the same time, soil itself releases water into water storage module 11. When the water depth in water storage module 11 exceeds 100mm, water is discharged through side drain 10.

[0065] This invention uses a humidity sensor to detect the soil at the location of plant roots and adjusts the height of the water tank to achieve a dynamic balance between the water pressure at the water tank outlet and the water pressure in the soil irrigation pipe. The dynamic adjustment module absorbs water from the water storage module to ensure uniform soil moisture. When the soil moisture exceeds a specified value, the water in the soil is discharged through the dynamic adjustment module and soil water separation.

[0066] This invention achieves dynamic regulation of soil moisture by adjusting the water tank supply system and automatic micro-adjustment module, and through automatic compensation methods of water tank height, water suction module and propeller, thereby achieving uniform soil moisture and micro-adjustment of water supply and drainage; ensuring uniform soil moisture in staggered balconies, and achieving automatic regulation and dynamic balance of soil moisture.

[0067] This invention first adjusts the height of the water tank support based on humidity monitoring, so that the resistance of soil moisture to irrigation water pipes and the water head pressure in the water tank are dynamically balanced; the water inlet pipe inside the water tank is controlled by a mechanical float valve to keep the water tank at a certain water level.

[0068] When the soil moisture is low, the irrigation pipe automatically dispenses water; when the soil moisture is much higher than that of the soil where the plants are planted, the irrigation pipe stops dispensing water; the water absorption module finely adjusts the soil moisture, and when the soil moisture is low, the water absorption module draws water from the water storage module to replenish the soil moisture.

[0069] When the soil moisture is high, the water in the water-absorbing module can be squeezed out by pushing the push rod, and then discharged from the garden area through the water storage module and the side drain. When the electric push retracts, the water-absorbing module absorbs water from the soil during the recovery process, and the water in the soil is gradually removed as the push rod repeatedly squeezes the water-absorbing module. When the soil moisture is far higher than the moisture required for plant growth, the water in the soil is discharged by repeatedly squeezing the water-absorbing module and the soil itself through the push rod.

[0070] This invention enables automatic water replenishment of the water supply tank and automatic irrigation of the irrigation pipe; it can automatically adjust soil moisture to make the soil moisture more uniform; when the soil moisture is low, the water storage module can reduce water waste; when the soil moisture exceeds the specified value, the water absorption module and the soil self-extraction ability are used to drain the water in the soil from the balcony garden in a short time to meet the needs of plant growth; the system equipment is simple to install and operate, and can achieve automatic adjustment.

[0071] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.

9. The construction method of the automatic soil moisture compensation device for planting on a staggered balcony according to claim 1, characterized in that: The construction method includes the following steps: Step 1: Install the water tank supply system. Fix the height-adjustable bracket (4) at a suitable position on the staggered balcony. Install the irrigation water tank (3) on the height-adjustable bracket (4). Connect one end of the metal inlet hose (1) to the PPR water supply pipe with a diameter of DN15 on the balcony through the water supply angle valve. Connect the other end to the irrigation water supply float valve (2). Then connect the irrigation water supply float valve (2) to the irrigation water tank (3). Connect one end of the plastic outlet hose (5) to the irrigation water tank (3) and the other end to the multi-hole irrigation water pipe (13). Lay the multi-hole irrigation water pipe (13) in the upper nutrient soil (16) of the garden planting area (17). Step 2: Install the soil moisture monitoring and control system and the automatic micro-adjustment module. Bury the moisture sensor (9) in the upper nutrient soil (16). Connect the moisture sensor (9) to the moisture monitoring controller (7) through the RS485 data cable (6). Connect the moisture monitoring controller (7) to the electric propeller (12) through the power cable (8). After assembling the tubular water absorption module (15) and the cuboid water absorption module (14), connect the cuboid water absorption module (14) to the propulsion plate of the electric propeller (12). Then place the lower part of the automatic micro-adjustment module in the groove of the water storage module (11). Step 3: Install the water storage module (11) and the side drain (10). Lay the water storage module (11) on the bottom of the garden and make holes in the side wall of the water storage module (11) to install the side drain (10). Step 4: System debugging and operation. Start the humidity monitoring controller (7), adjust the height of the height-adjustable bracket (4) according to the predetermined soil humidity required for plant growth, so that the water outlet pipe of the irrigation water tank (3) and the porous irrigation water pipe (13) form a dynamic pressure balance, test the operating status of each component, and ensure that the humidity monitoring, water replenishment and drainage functions are normal.

10. The construction method of the automatic soil moisture compensation device for planting on a staggered balcony according to claim 9, characterized in that: During system operation, when the soil moisture is less than the predetermined value, the irrigation water tank (3) supplies water to the porous irrigation water pipe (13) through the plastic water outlet hose (5). At the same time, the tubular water absorption module (15) and the cuboid water absorption module (14) of the automatic micro-adjustment module absorb water from the water storage module (11) and replenish the soil. When the soil moisture is greater than the predetermined value, the irrigation water tank (3) stops supplying water to the porous irrigation water pipe (13). The humidity sensor (9) transmits the detection data to the humidity monitoring controller (7). The humidity monitoring controller (7) controls the electric propeller (12) to repeatedly compress the cuboid water absorption module (14) and discharge the water to the water storage module (11). At the same time, the soil itself releases water to the water storage module (11). When the water depth in the water storage module (11) exceeds 100mm, the water is discharged through the side drain (10).
