[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The purpose of the present invention is to provide a photovoltaic panel condensate water collection and drip irrigation system and its use method to solve the problems existing in the above-mentioned prior art, effectively collect photovoltaic panel condensate water and realize intelligent irrigation, improve plant survival rate, rationally utilize water resources, and reduce irrigation costs.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] This embodiment provides a photovoltaic panel condensate collection and drip irrigation system, including: a photovoltaic panel 1, a condensate generating mechanism 2, a water storage mechanism 3 and an intelligent drip irrigation mechanism 4, the photovoltaic panel 1 is installed in a photovoltaic field; the condensate generating mechanism 2 is arranged on the backlight side of the photovoltaic panel 1 to generate condensate under the action of the temperature difference between day and night and guide the condensate to flow downward and collect; the water storage mechanism 3 is connected to the bottom of the condensate generating mechanism 2 to collect the condensate generated by the condensate generating mechanism 2; one end of the intelligent drip irrigation mechanism 4 is connected to the water storage mechanism 3, and the other end is used to transport the condensate to the roots of plants 5 that need irrigation in the photovoltaic field. This realizes the effective collection of the condensate generated on the backlight side of the photovoltaic panel 1 due to the temperature difference between day and night, and transports it to the roots of plants in the photovoltaic field for irrigation, fully utilizing naturally formed water resources, reducing the additional consumption of irrigation water, improving the utilization efficiency of water resources, saving costs and complying with environmental protection concepts.

[0029] In a preferred scheme of this embodiment, the condensation water generating mechanism 2 includes a plurality of hydrophilic protrusions 21 and a plurality of hydrophobic grooves 22. The hydrophobic grooves 22 are arranged in sequence with the hydrophilic protrusions 21. The hydrophilic protrusions 21 are used to generate condensation water under the action of the temperature difference between day and night. The hydrophobic grooves 22 are connected and can guide the condensation water generated by the hydrophilic protrusions 21 to the water storage mechanism 3 at the bottom. This structure in which the hydrophilic protrusions 21 and the hydrophobic grooves 22 are arranged at intervals utilizes the hydrophilic protrusions 21 to increase the specific surface area formed by the condensation water, thereby accelerating the condensation of water vapor into water droplets; the connected hydrophobic grooves 22 provide a smooth diversion channel for the water droplets, which can quickly guide the condensation water to the water storage mechanism 3, thereby improving the collection efficiency of the condensation water.

[0030] In a preferred solution of this embodiment, the hydrophilic protrusion 21 is made of a material with a contact angle of less than 5°, and the hydrophobic groove 22 is made of a material with a contact angle of greater than 150°. The contact angle of the hydrophilic material is less than 5°, so that water vapor has good contact with the surface of the hydrophilic protrusion 21, which is more conducive to the adsorption and condensation of water vapor into water droplets, thereby improving the efficiency of condensed water generation; the hydrophobic groove 22 has a contact angle of greater than 150° and has strong hydrophobicity, which can effectively reduce the adhesion of water droplets in the groove, ensuring that the water droplets flow down the groove quickly and smoothly, thereby ensuring the high efficiency and smoothness of the condensed water diversion.

[0031] In a preferred solution of this embodiment, the hydrophilic protrusion 21 is sprayed with titanium dioxide nanomaterial, and the hydrophobic groove 22 is sprayed with fluorocarbon material. The titanium dioxide nanomaterial has good hydrophilicity and chemical stability, which can ensure that the hydrophilic protrusion 21 can play a long-term and stable role in promoting the generation of condensed water. At the same time, the nanomaterial can form a delicate surface structure and increase the adsorption sites for water vapor; the fluorocarbon material has extremely low surface energy, which can give the hydrophobic groove 22 excellent hydrophobic properties, and its chemical properties are stable, weather-resistant, and durable, ensuring the performance stability and service life of the entire condensed water generating mechanism 2.

[0032] In a preferred scheme of this embodiment, the hydrophilic protrusion 21 is a cylindrical or hemispherical structure with a diameter of 10 to 100 microns, the width of the hydrophobic groove 22 is 50-500 microns, and the depth of the hydrophobic groove 22 is 20-200 microns. The cylindrical or hemispherical structure can interact with water vapor molecules from multiple angles, providing a good geometric shape for the formation of water droplets. The appropriate size range (10-100 microns in diameter) ensures a balance between the specific surface area and the merging and growth of water droplets, which is conducive to the generation of condensed water; the width (50-500 microns) and depth (20-200 microns) of the hydrophobic groove 22 are designed to ensure that the water droplets pass through the diversion smoothly while avoiding problems such as poor diversion due to improper size or overly complex structure that is difficult to manufacture, thereby ensuring the diversion effect of condensed water and the rationality of the entire mechanism.

[0033] In a preferred embodiment of this invention, the photovoltaic panel condensate water collection and drip irrigation system further includes a V-shaped corrugated guide plate 23. The top end of the V-shaped corrugated guide plate 23 is seamlessly connected to the bottom of the condensate generating mechanism 2, and the other end is used to guide the condensate water to the water storage mechanism 3. The provision of the V-shaped corrugated guide plate 23 further optimizes the diversion path of the condensate water from the condensate generating mechanism 2 to the water storage mechanism 3. The V-shaped structure can make the condensate water more concentrated. Flowing along the corrugated grooves can effectively reduce the water flow velocity, facilitate the smooth guidance of the condensate water to the water storage mechanism 3, avoid problems such as water splashing or localized accumulation that reduce collection efficiency, and improve the stability and accuracy of the diversion.

[0034] In a preferred solution of this embodiment, the V-shaped corrugated guide plate 23 is made of anodized aluminum material, and the guide surface of the V-shaped corrugated guide plate 23 is laser-etched with a guide groove 231. The guide groove 231 is arranged along the direction of the condensate generating mechanism 2 and the water storage mechanism 3. The anodized aluminum material has good corrosion resistance and mechanical strength, which can ensure the long-term and stable use of the V-shaped corrugated guide plate 23 in outdoor environments; the laser-etched guide groove 231 is arranged along the flow direction of the condensate, which can further guide the flow direction of the condensate, enhance the diversion effect, and make the condensate flow into the water storage mechanism 3 more orderly. At the same time, it also helps to improve the uniformity of the water flow on the surface of the guide plate and reduce the risk of local water accumulation.

[0035] In a preferred embodiment of the present invention, the water storage mechanism 3 includes a horizontal trough 31, a dust screen 32, a filter screen, a vertical pipe 34, a main pipe 35 and a water storage tank 36. The horizontal trough 31 is used to be arranged below the V-shaped corrugated guide plate 23 to collect condensed water guided by the V-shaped corrugated guide plate 23. The dust screen 32 is arranged at the top opening of the horizontal trough 31. The top of the vertical pipe 34 is connected to and communicated with the bottom of the horizontal trough 31. The filter screen is arranged at the top of the vertical pipe 34. The bottom end of the vertical pipe 34 is connected to and communicated with the main pipe 35. The end of the main pipe 35 away from the vertical pipe 34 is connected to the water storage tank 36. The horizontal groove 31 can increase the collection area of condensed water, ensuring that the condensed water guided by the V-shaped corrugated guide plate 23 can be collected in time; the dust-proof screen 32 can prevent dust and other debris from entering the horizontal groove 31, avoid impurities from mixing with the condensed water, and ensure the cleanliness of the collected condensed water; the filter screen further filters out possible tiny impurities, thereby improving the quality of the condensed water entering the water tank 36; the connection structure of the vertical pipe 34, the main pipe 35 and the water tank 36 stably and orderly transports the collected filtered condensed water to the water tank 36 for storage, providing a clean and sufficient water source for subsequent irrigation.

[0036] Preferably, the intelligent drip irrigation mechanism 4 includes a controller, a water pump 41, a drip irrigation pipeline 42, multiple drip irrigation nozzles 43 and multiple soil moisture sensors 44. The water pump 41 is arranged in the water tank 36. One end of the drip irrigation pipeline 42 is connected to the water pump 41, and the other end is connected to each drip irrigation nozzle 43. The drip irrigation nozzles 43 are correspondingly arranged at the roots of each plant 5 to be irrigated in the photovoltaic field area. The soil moisture sensor 44 is installed in the soil near the root of each plant 5 to be irrigated to monitor the soil moisture conditions, and one soil moisture sensor 44 is correspondingly arranged to one drip irrigation nozzle 43. The controller is connected to the soil moisture sensor 44, the water pump 41 and the drip irrigation nozzle 43 signals. The intelligent drip irrigation mechanism 4 realizes precise control of plant irrigation. The soil moisture sensor 44 monitors the moisture condition of the soil at the roots of the plants in real time and transmits the data to the controller. The controller controls the start and stop of the water pump 41 and the water output of the drip irrigation nozzle 43 based on this data information. Irrigation is only started when the soil moisture is insufficient, avoiding waste of water resources caused by excessive irrigation. At the same time, it ensures that the soil moisture is always maintained at a level suitable for plant growth, thereby improving the irrigation effect and water utilization efficiency, which is conducive to the healthy growth of plants in the photovoltaic field.

[0037] The present invention also provides a method for using the photovoltaic panel condensate water collection and drip irrigation system according to any one of the above items, comprising the following steps:

[0038] Equipment installation and preparation

[0039] Photovoltaic panel 1 installation: The photovoltaic panel 1 is reasonably installed in the photovoltaic field according to the local lighting conditions, and the optimal orientation and tilt angle are selected to ensure that the photovoltaic panel 1 receives sufficient light and provide a suitable installation position for the condensation water generating mechanism 2.

[0040] Installation of condensation water generating mechanism 2: Install the condensation water generating mechanism 2 on the backlight surface of the photovoltaic panel 1 in strict accordance with the design requirements, ensuring that the hydrophilic protrusions 21 and the hydrophobic grooves 22 are evenly spaced and accurately set, ensuring the integrity and correctness of the device structure, and preparing for the subsequent generation and diversion of condensation water.

[0041] Installation of the V-shaped corrugated guide plate 23: seamlessly connect the top of the V-shaped corrugated guide plate 23 to the bottom of the condensate generating mechanism 2, and install the other end in conjunction with the water storage mechanism 3 to ensure that the guide plate has the correct direction of diversion, can smoothly and efficiently transport the condensate to the water storage mechanism 3, and the connection parts are well sealed to prevent water leakage.

[0042] Water storage mechanism 3 installation and preparation: Install and arrange the horizontal trough 31 below the V-shaped corrugated deflector 23. Install the dust screen 32, filter screen, vertical pipe 34, main pipe 35, and water storage tank 36, ensuring they are securely connected and tightly connected to form a reliable and continuous water flow path. Add an appropriate amount of disinfectant (depending on the water quality) to the water storage tank 36 for preliminary treatment to ensure stable and good water quality.

[0043] Installation and preparation of the intelligent drip irrigation mechanism 4: Install the water pump 41 in a suitable location within the water storage tank 36. Connect the drip irrigation pipes 42 and multiple drip irrigation nozzles 43, ensuring that the drip irrigation nozzles 43 are precisely positioned at the roots of the plants 5 to be irrigated within the photovoltaic field. Install the soil moisture sensor 44 in the soil near the roots of each plant 5 to be irrigated, ensuring that it is installed at an appropriate depth to accurately sense soil moisture. Complete the signal connection and debugging between the controller, the soil moisture sensor 44, the water pump 41, and the drip irrigation nozzles 43 to ensure the normal operation of the control system.

[0044] System operation and monitoring

[0045] Condensate collection stage: After the device is put into operation, as the temperature difference between day and night changes, the condensate generating mechanism 2 on the backlight side of the photovoltaic panel 1 begins to function. The hydrophilic protrusions 21 use their hydrophilicity and unique structure to increase the specific surface area in contact with water vapor, accelerating the condensation of water vapor into water droplets on the protruding parts. After the water droplets gather and grow to a certain extent, they roll down to the adjacent hydrophobic grooves 22. With the help of the hydrophobicity and connected structure of the hydrophobic grooves 22, the water droplets flow to the V-shaped corrugated guide plate 23, and the V-shaped corrugated guide plate 23 guides the condensed water to the horizontal groove 31. During this process, it is necessary to check the effect of condensate generation and diversion, and observe whether the hydrophilic protrusions 21 continue to effectively generate condensate, and whether the hydrophobic grooves 22 and the guide plates are blocked or have other drainage problems.

[0046] Condensate storage: Condensate collected from horizontal trough 31 passes through dust screen 32 and filter screen to remove dust and impurities before flowing through vertical pipe 34 and main pipe 35 into water storage tank 36 for storage. During this period, dust screen 32 and filter screen are regularly checked for need of cleaning or replacement to ensure the quality of water entering water storage tank 36. The water level in water storage tank 36 is also monitored to prevent overflow or low water levels that could affect subsequent drip irrigation.

[0047] During the intelligent drip irrigation phase, soil moisture sensors 44 monitor the soil moisture near the roots of each plant 5 within the photovoltaic field in real time and transmit this data to the controller. If the soil moisture in a particular area falls below the set irrigation threshold, the controller turns on the corresponding water pump 41 and adjusts the water flow rate from the drip irrigation nozzles 43 for drip irrigation. When the soil moisture reaches the appropriate range, the controller turns off the water pump 41, halting drip irrigation. During this process, the accuracy of the data transmitted by the soil moisture sensors 44 and the controller's control of the water pumps 41 and drip irrigation nozzles 43 must be periodically checked to ensure that plants in each area receive the appropriate amount of irrigation when needed.

[0048] Equipment maintenance and management

[0049] Regular inspection: Periodically inspect all components of the entire system to check whether there are stains or damage on the surface of the photovoltaic panel 1 that affect the production of condensed water; whether there are impurities attached to the hydrophilic protrusions 21 and hydrophobic grooves 22 of the condensed water generating mechanism 2 or structural changes; whether the V-shaped corrugated guide plate 23 is corroded or deformed, affecting the diversion effect; whether the components of the water storage mechanism 3 are damaged or blocked, affecting the water quality and water storage capacity; whether the sensors of the intelligent drip irrigation mechanism 4 are monitoring accurately, and whether the water pump 41 and drip irrigation nozzles 43 are operating normally.

[0050] Cleaning and Maintenance: Perform appropriate cleaning and maintenance based on the inspection results. Clean dust and debris from the photovoltaic panel 1; remove impurities from the hydrophilic protrusions 21 and hydrophobic grooves 22; clean or replace the guide grooves 231 of the V-shaped corrugated guide plate 23; clean the dust screen 32 and filter screen; regularly clean and disinfect the water tank 36; calibrate the sensors of the intelligent drip irrigation mechanism 4; and inspect and repair the water pump 41 and drip irrigation nozzles 43.

[0051] Data Analysis and Adjustment: Record and analyze data from system operation, such as the amount of condensed water collected in different seasons and weather conditions, irrigation requirements for different plants at different growth stages, and changes in soil moisture. Based on this data analysis, system operating parameters, such as drip irrigation thresholds and irrigation times, are rationally adjusted to continuously optimize system performance and water resource efficiency.

[0052] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
