At the same time, the modularity facilitates later maintenance and part replacement, significantly reducing the operation and maintenance cost of the whole life cycle.

[0024] In an embodiment, the base 110 is an aluminum alloy base, the bottom of which is pasted with a non-slip pad and has a built-in mounting hole; the column 120 is a wooden structure, the bottom of which is provided with a flange plate, and the flange plate is rigidly connected with the top of the base 110.

[0025] The base 110 is fixed to the balcony floor by the non-slip pad (such as nitrile rubber) and mounting hole at the bottom of the base 110, and the column 120 (such as ACQ corrosion-resistant pine) is fixed with a flange plate at the bottom, and the flange plate is rigidly connected with the reserved threaded hole at the top of the base 110 by bolts, forming a stable support foot.

[0026] The balance between light weight and high strength is achieved. The base 110 made of aluminum alloy is light in weight, corrosion-resistant, convenient for transportation and installation; the column 120 of wooden structure provides good structural strength and natural decorative beauty. The composite structure takes into account durability, bearing capacity and beauty, which is better than single metal or wooden support.

[0027] In an embodiment, the hydroponic pipe 210 is made of food-grade PPR material, the pipe body is provided with planting holes of the same diameter along the length direction, and the planting basket 212 is fitted in the hole; the inner wall of the hydroponic pipe 210 is sprayed with a slow-release nutrient solution coating; the water supply and drainage and filtration system includes a silica gel plug at both ends of the hydroponic pipe 210, a water inlet pipe connected to one side of the hydroponic pipe 210, a drainage pipe 320 connected to the other side, and a water infiltration filter tank 330 arranged below the hydroponic pipe 210, and a stainless steel detachable filter screen is arranged in the filter tank 330.

[0028] Food-grade PPR pipe is used as the main body of the hydroponic pipe 210, and holes with a diameter of 50 mm are opened at an interval of 150 mm and embedded with ABS planting baskets 212.

[0029] The core goal of "low maintenance" is achieved. The slow-release coating extends the nutrient supplementing period to 1-2 months; the planting basket 212 and the filter tank 330 effectively prevent root water accumulation and pipe blockage, and the residue cleaning frequency is reduced to once a month. Color-coded pipes facilitate installation identification and later maintenance.

[0030] In an embodiment, the inner diameter of the pipe clamp in the connecting assembly is matched with the outer diameter of the hydroponic pipe 210, and the pipe clamp is fixed in the preset clamping groove of the stand 120 by bolts; the pipe clamp can be adjusted up and down in the range of 0-500 mm along the stand 120.

[0031] An ABS pipe clamp with an inner diameter closely matched with the outer diameter of the hydroponic pipe 210 is installed at both ends of the hydroponic pipe 210. The stand 120 is provided with a clamping groove on the side surface, and the pipe clamp is fixed in the clamping groove by bolts. By loosening / tightening the bolts fixed in the clamping groove of the stand 120, the position of the hydroponic pipe 210 can be adjusted, i.e., the height of the hydroponic pipe 210 can be adjusted to an appropriate height in the range of 0-500 mm.

Users can flexibly adjust the height of the hydroponic pipe 210 according to the type of plants to be planted (such as low-growing vegetables, medium-sized flowers, and high-stem green plants), realize three-dimensional planting, and maximize the use of balcony space. At the same time, the quick disassembly and assembly design makes installation and maintenance simple and efficient.

[0033] In an embodiment, the wind-resistant reinforcing assembly forms a two-level wind-resistant system of "side pull bars and transverse stabilizing bars".

[0034] The side pull bars (6 mm diameter galvanized steel ropes) are connected to the top of the stand 120 and the anchor embedded in the ground at an inclination angle of 30°, and are tensioned to 1500 N by a tensioner. A galvanized steel pipe (diameter 50 mm) with a wall thickness of 3 mm is used as a transverse stabilizing bar, which is connected to adjacent stands 120 by a hoop (matched with the middle part of the stand 120), and passes through the inside of the hydroponic pipe 210 for fixing the hydroponic pipe 210 and the planting basket 212, thereby improving the overall wind load.

[0035] Significantly improve the device in the high balcony environment of wind stability. Side pull effectively resist horizontal tension, transverse stability bar to prevent the relative displacement between the column 120, the overall framework can effectively resist 8 level instantaneous through the wind, to ensure the safety in bad weather.

All exposed water culture pipes 210, water inlet pipes and drain pipes 320 are wrapped with 25mm thick heat preservation sleeves and the joints are sealed. A self-limiting temperature electric heating tape is provided at the bottom of the water culture pipe 210, and a temperature sensor 410 is installed in the pipe. The temperature sensor 410 sensor and the electric heating tape are configured with an anti-freezing switch 420 with an indicator light, and the anti-freezing switch 420 is linked with the unit-level control box. When the temperature is ≤5℃, the electric heating tape is automatically triggered to heat, and when the temperature is ≥10℃, it is automatically turned off, which reduces energy consumption compared with manual operation.

[0038] The "unattended" winter anti-freezing protection is realized. The intelligent linkage system is more timely and reliable than manual operation, which avoids pipe cracking and equipment damage caused by forgetting to turn on the anti-freezing measures, and reduces energy consumption compared with manual operation through precise temperature control.

[0039] In an embodiment, the centralized and intelligent functions of the unified management assembly are realized. In the unified management assembly: the centralized water supply and drainage interface 520 is a stainless steel quick connection interface, which is provided on the side of the base 110, and a single interface can be connected in parallel with multiple groups of water inlet pipes or drain pipes 320; the intelligent liquid level sensor is a capacitive type, embedded in the bottom of the water culture pipe 210, and transmits data; the unit-level control box supports LCD screen display, low liquid level sound and light alarm, and timing water replenishment function, and is connected to the property management platform through a 4G module.

[0040] The centralized water supply interface 510 and the drainage interface 520 are arranged on the side of the base 110, the water inlet pipe and the drainage pipe 320 of the multiple groups of water culture pipes 210 are connected in series, the water inlet pipe is communicated with the water inlet 610 through the water supply interface 510, and the drainage pipe 320 is communicated with the drainage outlet 620 through the drainage interface 520. A capacitive liquid level sensor is installed at the bottom of the water culture pipe 210, and data is sent to the unit level control box through the RS485 protocol. The unit level control box realizes data display, low liquid level alarm, timing water replenishment, and uploads data to the property platform through the 4G module. When the liquid level sensor detects that the liquid level in the water culture pipe 210 decreases to the lowest water level, water is replenished in the water culture pipe 210 through the water inlet 610, the water supply interface 510 and the water inlet pipe. Timing water replenishment can also be set at specific times.

[0041] Intensive management and efficiency leap are realized. Property management personnel do not need to check each house, and can remotely monitor the device state of a whole building on the central platform. The liquid level monitoring time is shortened from 2 hours per building to 5 minutes per building, and the water replenishment operation is changed from being performed in each house to being completed centrally, so that the management efficiency is improved by 80%.

[0042] In an embodiment, the water seepage filter tank 330 is made of aluminum alloy, and the built-in filter screen has a pore size of 0.5 mm; The bottom interface of the water seepage filter tank 330 is connected with the drainage outlet 620. The water seepage filter tank 330 is made of aluminum alloy with a wall thickness of 5 mm, and a stainless steel filter screen with a pore size of 0.5 mm is built in. When installing, it is ensured that the bottom of the filter tank 330 has a drainage slope of 3 ‰, so that the filtered wastewater can be smoothly drained into the unified pipe network.

[0043] The water discharged from the water seepage filter tank 330 and the water culture pipe 210 drainage pipe 320 is collected through the drainage outlet 620, realizing the recycling of water resources and the self-cleaning of the system. Fine filtering avoids clogging of the drainage outlet 620, and the collected seepage water can be recycled, improving water saving rate. The aluminum alloy material ensures the durability and light weight of the tank body.

[0045] Step 2: Modular installation of hydroponic pipe assembly: According to the width of the balcony, select the appropriate size of the hydroponic pipe 210, embed the planting basket into the planting hole on the hydroponic pipe 210, and use interference fit to ensure that the planting basket is not loose and to avoid the shaking of the green plant roots. Use pipe clamps to fix the hydroponic pipe 210 in the pre-set clamping groove of the stand column 120, adjust the levelness of the hydroponic pipe 210 with a level, with an error ≤1mm / m, and ensure that the water inlet end of the hydroponic pipe 210 is slightly higher to facilitate the discharge of excess liquid. Connect the water inlet pipe and the drain pipe 320 at both ends of the hydroponic pipe 210, and deploy a water seepage filter tank 330 below the hydroponic pipe 210.

[0046] Step 3: Precise configuration of wind-resistant reinforcement assembly: Install 3 side-pulling bars between every 2 stand columns 120, one end of which is hung on the top hanging ring of the stand column 120 through a U-shaped hook, and the other end is connected to a ground anchor; the ground anchor needs to be embedded into the balcony floor by ≥100mm, and then fixed by pouring C30 concrete, and cured for 72h to reach the strength standard; use a tensioner to tension the side-pulling bar to 1500N (error ±50N), and use a protractor to calibrate the inclination angle of the side-pulling bar to 30° to maximize the dispersion of the wind load. Fix the transverse stabilizing rod to the middle part of the stand column 120 through a special hoop, splice adjacent transverse stabilizing rods with a four-way joint, and wrap raw tape around the joint for sealing; the bolt torque of the hoop is set to 15N m to prevent the transverse stabilizing rod from loosening, forming a continuous horizontal support frame to improve the overall wind resistance.

[0047] Step 4: Integration of freeze-proofing and unified management assembly: Wrap the hydroponic pipe 210, water inlet pipe and drain pipe 320 with a heat preservation sleeve, fix the electric heating tape and temperature sensor 410 in the hydroponic pipe 210, and connect the water inlet pipes and drain pipes 320 of multiple hydroponic pipe 210 groups in parallel. The water inlet pipe is connected to the water inlet 610 through the water supply interface 510, and the drain pipe 320 is connected to the drain outlet 620 through the drain interface 520. Install a capacitive liquid level sensor at the bottom of the hydroponic pipe 210; connect the freeze-proofing assembly and the liquid level sensor to the unit-level control box, which can control the opening and closing of the freeze-proofing assembly and the opening or closing of the water inlet 610.

[0048] A standardized and replicable installation process is provided, which ensures that different installers can achieve the same quality standards and performance effects, improves the assembly efficiency by 60%, and fundamentally reduces the failure rate caused by improper installation.

[0049] The application also provides a freeze-proofing control method, comprising: Real-time monitoring of the liquid temperature in the hydroponic pipe 210 by the temperature sensor 410; When the temperature is monitored to be ≤5℃, the unit-level control box automatically triggers the electric heat tracing band to start heating; When the temperature is monitored to be ≥10℃, the unit-level control box automatically controls the electric heat tracing band to stop heating; The anti-freezing switch 420 supports manual triggering, and can link to control the electric heat tracing bands of 3-5 groups of devices in the same unit to be started synchronously.

[0050] The automatic control logic of the anti-freezing system is described: continuous monitoring→low-temperature triggering (≤5℃)→heating→high-temperature shutdown (≥10℃). Manual intervention is also reserved, and the electric heat tracing bands of all devices in the same unit can be forcibly started through the anti-freezing switch 420.

[0051] The anti-freezing strategy provides double insurance. The fully-automatic control guarantees efficient energy saving and unattended operation under normal conditions; the manual triggering function provides an emergency response measure in case of failure of the sensor or the controller, greatly enhancing the reliability and robustness of the system and reducing the damage rate of the device under low temperature.
