Technical Field
[0001] This invention belongs to the field of vertical greening technology, specifically relating to a vertical greening energy-saving device based on the principle of communicating vessels. Background Technology
[0002] Currently, the development of vertical greening technology on the market shows a diversified trend, mainly including angle-adjustable, composite swing, and intelligent control types. These devices generally achieve automated irrigation through motor drive and pipeline systems, and have achieved certain results in solving the problems of small irrigation area of fixed sprinklers and increasing coverage. However, a comprehensive analysis of existing technologies reveals the following common defects in current vertical greening irrigation devices: 1. Irrigation System and Technical Challenges In cases of large-scale plant death in green walls and rooftop greening projects, the majority of plant deaths are caused by problems with the irrigation system. Large fluctuations in water pressure can cause pipe bursts or drippers failing to supply water at the highest point; flawed pipe design (such as pipes that are too narrow to allow insufficient flow, or excessive water loss leading to insufficient pressure) can also affect irrigation effectiveness. Furthermore, the overall system drainage needs to be integrated with the building's surface drainage system; otherwise, watermarks may be visible on the ground and walls, affecting the environment's aesthetics and cleanliness. Similarly, unlike traditional ground planting, achieving uniform and effective irrigation in vertical greening is a technical challenge. Irrigation systems suffer from poor reliability and low water utilization: existing active irrigation systems have extremely high requirements for water pressure stability and pipe design; sprinkler irrigation suffers from significant water evaporation loss, and drip irrigation is prone to clogging, both resulting in water waste and an inability to automatically adjust water supply according to the actual water needs of the plants.
[0003] Therefore, it is necessary to precisely control the water requirements of each plant to avoid overwatering leading to root rot or water shortage causing drought. For commonly used plant varieties, the amount of irrigation water needs to be calculated based on the plant's characteristics each time the variety is changed, and it also needs to be controlled according to changes in weather temperature and humidity. Therefore, an extremely precise irrigation system is required. However, the initial investment in a precision irrigation system is too large, and the returns are comparable to those of a traditional drip irrigation system. Therefore, the overall investment and returns are not ideal.
[0004] 2. Plant selection and ecological limitations Currently, the plants used in vertical greening are mainly climbing plants and shrubs / herbs, with about 30 species commonly used. This seriously affects urban biodiversity and fails to effectively highlight the characteristics of urban landscaping. This is primarily because some plants cannot adapt well to the unique growing environment of vertical greening. Furthermore, changing plant species in common vertical greening planting troughs requires a complete overhaul of the drip irrigation system or a rearrangement of the irrigation network, making the process extremely complex. Therefore, common vertical greening planting troughs rarely have their plant species changed; they are often used for a long time before being replaced in large quantities at once, resulting in enormous plant usage and cost. Additionally, the fixed-angle design cannot adapt to sloping or curved building surfaces, limiting its application scenarios. 3. Economic Costs and Maintenance Requirements High construction costs: The cost of planting troughs and planting mats ranges from 1,000 to 6,000 yuan per square meter, resulting in huge initial investment costs. Furthermore, subsequent management involves irrigation systems, structural systems, plant replacement, etc., leading to relatively high maintenance costs. The irrigation mode is also limited, resulting in poor adaptability to different scenarios. The intertwined irrigation network and rotating mechanism make plant replacement difficult and lead to a high failure rate. Existing devices are mostly designed for single facade forms, making it difficult to adapt to various facade scenarios such as vertical walls, flat roofs, and sloping walls simultaneously. This poor versatility limits the promotion and application of vertical greening in different scenarios. High energy consumption and costs: Existing devices generally rely on electrically driven sprinkler or drip irrigation systems. Initial equipment investment is large, and subsequent operation and maintenance costs are high, resulting in an overall unsatisfactory return on investment. They are energy-intensive but lack reliability.
[0005] In summary, existing vertical greening systems have significant drawbacks and shortcomings in terms of irrigation system reliability, plant selection diversity, and the economics and convenience of long-term maintenance. Therefore, it is necessary to provide a vertical greening energy-saving device based on the principle of communicating vessels to solve the aforementioned technical problems. Summary of the Invention
[0006] The purpose of this invention is to provide a three-dimensional greening energy-saving device based on the principle of communicating vessels, which solves the shortcomings of existing three-dimensional greening devices, such as poor reliability and high maintenance costs of irrigation systems.
[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A three-dimensional greening energy-saving device based on the principle of communicating vessels includes a physical execution module, which includes a planting trough, a water replenishment trough, and an automatic water replenishment mechanism; the bottom of the planting trough has a water exchange hole, and a water-absorbing cotton strip is provided at the water exchange hole; the planting trough is located above the water replenishment trough, and the planting trough and the water replenishment trough are connected through the water exchange hole; the water replenishment trough and the automatic water replenishment mechanism are connected through a communicating vessel.
[0008] In this invention, the absorbent cotton strip is placed in the water exchange hole, with one end inserted into the planting substrate in the planting trough and the other end inserted into the water replenishment trough.
[0009] Furthermore, the diameter of the water exchange hole is 5mm, and the length of the absorbent cotton strip is 15cm.
[0010] Furthermore, the bottom of the planting trough is also evenly distributed with water passage holes around the water exchange holes, and the diameter of the water passage holes is 3mm.
[0011] In this invention, the planting trough and the water replenishment trough are movably connected.
[0012] Furthermore, a support frame is fixedly connected to the water replenishment tank, and the planting trough is connected to the support frame through a rotating slot, so that the planting trough can rotate relative to the water replenishment tank.
[0013] Furthermore, a rotating conductive slip ring and a water channel rotary joint are provided at the rotation axis of the planting trough.
[0014] In some embodiments of the present invention, a drain hole is provided on the side of the water replenishment tank. The drain hole controls the maximum liquid level in the water replenishment tank; when the internal water level exceeds the limit, it will be automatically discharged through the drain hole.
[0015] In this invention, the automatic water replenishment mechanism includes a water supply tank, an inlet pipe, and a float; the bottom of the water supply tank has a connecting opening, the float is located inside the water supply tank, and the top of the float has a sealing opening, so that water enters the water supply tank along the inlet pipe, the float rises and seals the inlet pipe, thereby automatically adding a certain amount of water and then stopping the water flow.
[0016] Furthermore, the automatic water replenishment mechanism is connected to one end of the communicating vessel via a connecting port, and the water replenishment tank is connected to the other end of the communicating vessel.
[0017] In some embodiments of the present invention, the communicating vessel includes two communicating channels and a communicating pipe; the two communicating channels are connected by the communicating pipe, one communicating channel is connected to a water replenishment channel, and the other communicating channel is connected to an automatic water replenishment mechanism.
[0018] In some embodiments of this invention, multiple sets of planting troughs and watering troughs are provided. Adjacent watering troughs arranged horizontally are connected sequentially via connectors; adjacent watering troughs arranged vertically are connected via pipelines. This invention can construct a composite irrigation mode combining vertical and horizontal irrigation. Vertically, gravity-fed irrigation using multiple planting troughs connected in series creates a waterwheel-like vertical irrigation effect; horizontally, a rotatable ring-shaped pipe network design enables horizontal rotation irrigation, ensuring uniform light exposure for the plants. This system can adapt to various exterior facade scenarios, including vertical walls, flat roofs, and sloping walls, achieving comprehensive coverage of three-dimensional irrigation, flat irrigation, and sloping irrigation.
[0019] In this invention, the planting substrate in the planting trough comprises the following components in the following weight ratio: peat moss: humus: coconut coir: perlite: sphagnum moss = 2:4:1:1:1. By optimizing the planting substrate ratio, plants can absorb water autonomously according to their own water requirements, avoiding overwatering or drought, eliminating the need for precise control of irrigation, and significantly reducing system complexity.
[0020] The invention also includes a rainwater collection module, which is equipped with a rainwater collection tank and is connected to the physical execution module.
[0021] Furthermore, the capacity of the rainwater collection box is calculated based on the average daily water requirement of different plants, using the formula R = (X + Y + Z). D, where R is the capacity of the rainwater collection tank; X, Y, and Z are the average daily water requirements of different plants; and D is the number of planting days.
[0022] The invention also includes a sensing and monitoring module, which is equipped with intelligent multi-parameter sensors deployed in the planting trough, including a substrate humidity sensor, an ambient temperature and humidity sensor, and a light sensor.
[0023] The present invention also includes a cloud platform data collection and processing module, which is connected to the sensing and monitoring module via a wireless communication unit.
[0024] Furthermore, the cloud platform data collection and processing module executes a plant transpiration prediction model trained based on historical data to predict water demand in advance.
[0025] Furthermore, the plant transpiration prediction model trained based on historical data automatically reduces the water supply to Q0×0.3 6 hours before rainfall, based on rainfall forecasts obtained from the meteorological API; when dh / dt is detected to be negative for 2 consecutive hours and Q=Qmax, a fault warning is generated; the humidity upper limit H high A humidity level of 34% will trigger drainage (opening the drain solenoid valve for 5 minutes). A humidity target Hset of 30% will maintain normal water supply; the lower humidity limit H... low When the water level reaches 26%, initiate rapid water replenishment (flow distribution valve opening 100%); Drought warning H dry Send an app push notification when the growth rate reaches 22%, and adjust the notification every 7 days based on the plant's growth stage: Seedling stage H set -2%, Maturity H set +2%.
[0026] The present invention has the following beneficial effects: (1) The three-dimensional greening energy-saving device based on the principle of communicating vessels adopts the principle of communicating vessels and uses the water level difference to automatically replenish water. It does not require water pumps and electric drive, and completely solves the irrigation failure problem caused by water pressure fluctuation, achieving energy saving, environmental protection and high reliability.
[0027] (2) The rotating planting trough of the present invention, through modular design, eliminates the need to rearrange the irrigation network when changing plant varieties. It only requires simple replacement of the planting trough, which greatly improves the convenience of plant replacement and provides support for increasing biodiversity.
[0028] (3) This invention controls the water level through a float valve, automatically replenishes water and prevents water waste, reduces the need for manual maintenance and lowers long-term maintenance costs. In terms of water saving, a comparison is made between the long-term drip irrigation water consumption and the water supply of this device. Compared with the former, the latter achieves a water saving rate of 85%, which is a larger amount of water saved than drip irrigation water consumption, and there is no problem of plant root rot caused by excessive watering.
[0029] (4) In terms of installation, compared with drip irrigation devices on the market, this device is easy to install and replace. It does not require a large-scale drip irrigation network. The water storage tank can be arranged horizontally, vertically, or longitudinally. Only one water supply tank is needed to meet the water needs of the entire device. At the same time, when it is necessary to change the plant varieties in the later stage, it is only necessary to simply remove the internal planting trough and replace it with a new planting trough. There is no need to set data such as drip irrigation water volume. It utilizes the self-watering characteristics of plants to achieve self-sufficiency. In terms of maintenance, this device does not require manual control. Based on the physical principle of communicating vessels and the self-watering characteristics of plants, there is no need for manual watering, no need to set the irrigation volume, and no need to calculate the water requirements of plants. This greatly reduces the initial artificial research and development investment and the later maintenance costs. Attached Figure Description

Detailed Implementation
[0032] like Figure 1-5 The three-dimensional greening energy-saving device shown is based on the principle of communicating vessels and includes a physical execution module 100.
[0033] The physical execution module 100 includes a planting trough 1, a water replenishment trough 2, and an automatic water replenishment mechanism 7; the bottom of the planting trough 1 has a water exchange hole 6, and a water-absorbing cotton strip is provided at the water exchange hole 6; the planting trough 1 is located above the water replenishment trough 2, and the planting trough 1 and the water replenishment trough 2 are connected through the water exchange hole 6; the water replenishment trough 2 and the automatic water replenishment mechanism 7 are connected through a connector.
[0034] In this embodiment, the planting trough 1 is a cube with a side length of 10cm, open at the top, and has a 5mm diameter water exchange hole 6 at the bottom. Around the water exchange hole 6, 30 3mm diameter water passage holes are evenly distributed. A 15cm long absorbent cotton strip is placed inside the water exchange hole 6, with one end inserted into the planting substrate in the planting trough 1. The planting substrate in the planting trough 1 comprises the following components in the following weight ratio: peat moss: humus: coconut coir: perlite: sphagnum moss = 2:4:1:1:1. The other end of the absorbent cotton strip is inserted into the water replenishment trough 2, forming a channel for the plant's self-watering mechanism.
[0035] In this embodiment, a support frame 5 is fixedly connected to the watering trough 2, and the planting trough 1 is connected to the support frame 5 via a rotating slot 4, allowing the planting trough 1 to rotate relative to the watering trough 2. The planting trough 1 can rotate 0 degrees, 45 degrees, and 90 degrees. When rotated to 0 degrees, it can be used for roof gardens, ground planting, and other flat surfaces. Through the communicating vessel device, the watering surface height can be kept consistent over a large area, ensuring sufficient water absorption by the plants. When rotated to 45 degrees, it can be used for vertical greening or slope greening. When rotated to 90 degrees, it can be used for vertical greening, bridge and road greening, and other types of greening. Through the rotating slot 4, the planting trough 1 can be rotated to a certain angle before installation and then installed uniformly, or it can be rotated after installation is complete. The planting trough 1 is equipped with a rotating conductive slip ring and a water circuit rotary joint at the rotating axis. During the rotation, the contact state between the substrate and the water storage area in the planting trough 1 is automatically changed through the gravity switching principle. Water is cut off when rotating (to prevent overflow) and water is replenished when stationary. The water supply of the trough can also be automatically adjusted according to the rotation angle (more water is supplied when the sun-facing side evaporates faster). The final effect is to achieve the synergistic optimization of "light-chasing behavior" and "irrigation behavior" in vertical greening.
[0036] The automatic water replenishment mechanism 7 includes a water supply tank 9, an inlet pipe 10, and a float 11. The water supply tank 9 has a connecting port 12 at its bottom. The float 11 is located inside the water supply tank 9, and its top has a sealing port 13. The inlet pipe 10 is connected to a faucet via a pipe. When the faucet is turned on, water enters the water supply tank 9 along the inlet pipe 10. The float 11 rises and seals the inlet pipe 10, automatically adding a certain amount of water and then stopping the flow. The automatic water replenishment mechanism 7 is connected to one end of a connecting device via the connecting port 12, and the water replenishment tank 2 is connected to the other end of the connecting device. The connecting device includes two connecting slots 3 and a connecting pipe 8; the two connecting slots 3 are connected by the connecting pipe 8, with one connecting slot 3 connected to the water replenishment tank 2 and the other connecting slot 3 connected to the automatic water replenishment mechanism 7. In this embodiment, multiple sets of planting troughs 1 and water replenishment tanks 2 are provided. Adjacent water replenishment tanks 2 arranged horizontally are connected sequentially via connecting devices; adjacent water replenishment tanks 2 arranged vertically are connected via pipes. During the specific construction process, the water supply tank 2 is fixedly installed on the wall or hanging net by hooks, or it can be placed flat on the roof or ground. A 20mm diameter hole is opened in the center of the bottom of the water supply tank 2. The lower end is connected to a PVC pipe through a PVC drain connector, and then connected to another PVC pipe through a 90-degree elbow. After that, a tee is connected. The upper end of the tee is connected to the bottom of another water supply tank 2, and the two ends are connected to PVC pipes. Finally, the end of the PVC pipe is connected to a 90-degree elbow, and the other end of the 90-degree elbow is connected to the bottom of the water supply tank 9, forming a complete communicating vessel assembly.
[0037] In this embodiment, a 5mm wide and 50mm long drain hole is chiseled out on the side of the water tank 2, 4.5cm from the bottom. When the internal water level exceeds the limit, it will automatically drain out through the drain hole, preventing the water level inside the device from becoming too high and submerging the plant roots, thus preventing the plant roots from rotting and dying. The water tank 2 is also equipped with a hook 19 for fixing the water tank 2 to the wall frame.
[0038] The working process of the three-dimensional greening energy-saving device based on the principle of communicating vessels is as follows: The water inlet pipe 10 of the automatic water replenishment mechanism 7 is connected to a faucet. After the water in the water supply tank 9 reaches a certain height, the automatic water replenishment mechanism 7 floats due to the buoyancy of the float 11, thus stopping the water flow. There is a water exchange hole 6 at the bottom of the planting trough 1, which is used to place water-absorbing cotton. After the plants and planting substrate are placed into the planting trough 1, the water level is maintained at a specific height through the communicating trough 3. After the water level drops, the float 11 in the automatic water replenishment mechanism 7 drops, the water stop opens, and water begins to enter. After reaching a certain height, the float 11 rises, the water stop stops, and the water inlet stops. Relying on the buoyancy device, the transpiration of the plants causes the substrate moisture to drop, thus replenishing water through the capillary action of the self-absorbing cotton. At this time, the water level in the water storage chamber drops slightly. Using the principle of communicating vessels balance, the water supply tank 9 automatically replenishes water to the water storage chamber. After the water level in the water supply tank 9 drops, the float valve opens, and finally tap water is added, and the system returns to balance. The whole process requires zero energy consumption and zero manual labor. The water level of the entire device can be kept at the set height at all times, continuously providing water to the plants.
[0039] The present invention also includes a rainwater collection module 200, a sensor monitoring module 300, a cloud platform data collection and processing module 400, and a user terminal interaction module 500.
[0040] The rainwater harvesting module 200 is equipped with a rainwater collection tank, which is connected to the physical execution module 100. The capacity of the rainwater collection tank is calculated based on the average daily water requirement of different plants, using the formula R = (X + Y + Z). D, where R is the capacity of the rainwater collection tank; X, Y, and Z are the average daily water requirements of different plants; and D is the number of planting days.
[0041] The sensing and monitoring module 300 is equipped with intelligent multi-parameter sensors deployed in the planting trough 1, including a substrate humidity sensor, an ambient temperature and humidity sensor, and a light sensor. When the substrate humidity sensor detects a change in the humidity content within the substrate, it outputs a signal and transmits it to the data collection terminal in real time. The ambient temperature and humidity sensor records changes in air temperature, humidity, and light intensity. The cloud platform module is mainly used for data storage and analysis. Data collected by the intelligent sensors is set to collect ambient temperature and humidity and light intensity data hourly, and water replenishment data every 12 hours. This data is collected and stored in the cloud platform data collection and processing module 400 for real-time viewing. By monitoring changes in substrate humidity, ambient temperature and humidity, and light intensity, the collected data is fed back to the data processing terminal. The user terminal interaction module 500 (such as an APP) monitors the daily irrigation water volume, sets the water level in the connecting trough 3, controls rainwater overflow and collection, balances the plant's water requirements and replenishment, and ensures normal plant growth.
[0042] The cloud platform data collection and processing module 400 is connected to the sensing and monitoring module 300 via a wireless communication unit. The cloud platform data collection and processing module 400 executes a plant transpiration prediction model trained based on historical data to predict water demand in advance. Based on rainfall forecasts obtained from the meteorological API, the plant transpiration prediction model automatically reduces the water supply to Q0×0.3 (Q0 is the preset initial water supply) 6 hours before rainfall. When it detects that dh / dt is negative for 2 consecutive hours and Q=Q... max When this occurs, a fault warning message is generated; humidity upper limit H high =34% will trigger drainage (open the drain solenoid valve for 5 minutes) Humidity target H set =30% is sufficient for normal water supply maintenance; lower humidity limit H low When the water level reaches 26%, initiate rapid water replenishment (flow distribution valve opening 100%); Drought warning H dry Send an app push notification when the growth rate reaches 22%, and adjust the notification every 7 days based on the plant's growth stage: Seedling stage H set -2%, Maturity H set +2%.
