Description

Technical Field

[0001] The present invention relates to the technical field of irrigation devices, and in particular to a plant watering device and method based on a photovoltaic power generation system. Background Art

[0002] Photovoltaic irrigation cleverly combines solar photovoltaic power generation and irrigation technology. Most devices currently on the market use solar photovoltaic power generation to power irrigation and water pumping systems. This method not only avoids the consumption of fossil energy and achieves zero environmental pollution, but also provides strong support for increasing agricultural income. However, plant growth is unique, and the growth process of each plant is different, and its water requirements at different growth stages also vary significantly. However, most current irrigation systems use a unified quantitative watering model. This "one-size-fits-all" approach cannot meet the individual needs of each plant and cannot provide plants with precise and meticulous care. In the long run, plants will find it difficult to achieve optimal growth, which may ultimately have a negative impact on crop yields.

[0003] The Chinese patent document (publication number: CN209251067U, patent title: A photovoltaic power generation irrigation device for agriculture) discloses the following technical content: it includes a photovoltaic panel, a mixing chamber, an irrigation pipe, a water pump, and a base. The base is topped with a bracket, the bracket is topped with a photovoltaic panel, the bracket is inside a water pump, the top of the water pump is mounted with a solar cell, the mixing chamber is mounted on one side of the solar cell, an electric motor is mounted on one side of the mixing chamber, a rotating rod is mounted on the output end of the electric motor, a stirring paddle is mounted on the outside of the rotating rod, a water outlet is mounted below the electric motor, a water valve is mounted on one side of the water outlet, a connector is mounted on one side of the water valve, and an irrigation pipe is mounted on one end of the connector. This utility model uses a nozzle to spray water into the air, which is dispersed into fine droplets and evenly distributed for irrigation. This irrigation method can provide a wide irrigation coverage and effectively utilize water resources.

[0004] As can be seen from the aforementioned implementation plan and accompanying drawings, while this photovoltaic irrigation system can utilize photovoltaic power to power a water pump for irrigation, it only provides uniform watering of plants. It lacks consideration for the states of different plants, or even the growth stages of the same plant, and cannot precisely deliver water based on actual needs. Consequently, it is difficult to provide comprehensive and personalized care for plants, hindering their ability to fully realize their growth potential and achieve optimal growth. Summary of the Invention

The plant cultivation module can control the degree of direct sunlight received by the plants by precisely adjusting the angle of the flower rack board, thereby creating the most suitable growth environment for different plants and promoting the healthy growth of the plants.

DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0025] like Figures 1 to 12 As shown, a plant watering device and method based on a photovoltaic power generation system includes a photovoltaic tracking power generation module A, a three-dimensional mobile watering execution module B, and a plant cultivation module C; Photovoltaic tracking power generation module A comprises a photovoltaic rack 1 and a photovoltaic panel 2 pivotally connected to the rack. Equipped with an intelligent tracking system, the panel 2 automatically adjusts its orientation based on the angle of sunlight, ensuring it always faces the sun, maximizing solar energy absorption and efficiently converting it into electricity. The panel 2 is strategically positioned directly above the plant cultivation module C, creating a system that couples solar energy with plant growth. During direct midday sunlight, the panel 2 provides shade and protection for the plants, preventing them from being damaged by the heat and creating a suitable growth environment.

[0026] The photovoltaic tracking power generation module A includes a photovoltaic angle adjustment power group 3, which includes a first motor 302. The first motor 302 is connected to a first driving gear 303, which is meshed with a first rack 304, which is meshed with a second passive gear 305, which is connected to one end of the photovoltaic panel 2; the first rack 304 is slidably connected to the first slide rail 301, which is connected to the photovoltaic rack 1, and a photoreceptor is provided on the photovoltaic panel 2. The photoreceptor is used to sense the angle of sunlight, and then the photovoltaic angle adjustment power group 3 is used to adjust the swing angle of the photovoltaic panel 2, so that the photovoltaic panel 2 can achieve intelligent light tracking.

[0027] The three-dimensional mobile watering execution module B includes a basic frame 4, which is connected to a watering pick-up component 7. The watering pick-up component 7 has excellent three-dimensional mobility and can move freely in the X, Y, and Z axis directions. This component integrates a clamp 704, a watering nozzle 706, and a visual recognition unit. The clamp 704 is powerful and can not only flexibly move the flower pot 11 within the plant cultivation module C, but also move the flower pot or potted plant with plants to the side of the telescopic component 6 for people to pick up. This design effectively solves the problem of inconvenience in picking up caused by the flower pot being placed too high. At the same time, by operating the clamp 704, the flower pot can be placed at a higher position, thereby improving the space utilization rate of the plant cultivation module C and fully tapping the potential of the planting space.

[0028] The visual recognition unit is equipped with a high-definition camera, which will take all-round photos of the plants before watering or relocating the flower pots 11. By comparing with the status of different growth stages of the plants preset in the system, accurate identification of the growth status of the plants can be achieved. At the same time, the unit can also keenly identify insects on plants. Once pests are found, the plants can be sprayed with pesticides or alarms can be issued according to the actual situation to remind staff to intervene in time. In addition, the visual recognition unit will accurately control the water output of the irrigation nozzle 706 according to the growth status and stage of the plant to achieve precise irrigation. By switching the water pipe connected to the irrigation nozzle 706, you can also flexibly choose to provide water, nutrient solution or spray pesticides to the plants, provide plants with refined and personalized maintenance services, and promote the healthy and strong growth of plants.

[0029] The adjustable angle plant cultivation module C includes a flower stand angle adjustment power group 10. The electric energy generated by the photovoltaic panel 2 is used to drive the photovoltaic panel angle adjustment power group 3, the flower stand angle adjustment power group 10 and the three-dimensional mobile irrigation execution module B. In addition, it can also supply power to the water pump, and use the water pump to pump water to the watering component 7 to water the plants, providing sufficient water source for watering the plants, realizing efficient energy utilization and stable operation of the system.

[0030] The plant cultivation module C includes a breeding base frame 8, which is connected to a flower rack plate 9. Both sides of the flower rack plate 9 are provided with inclined surfaces 901, and at least one flower pot positioning hole 902 is provided perpendicular to the inclined surface. One end of the flower rack plate 9 is connected to the flower rack angle adjustment power group 10; the flower rack angle adjustment power group 10 includes a second slide rail 103, which is connected to one side of the breeding base frame 8. The second slide rail 103 is slidably connected to a second rack 104. One end of the flower rack plate 9 is connected to a second passive gear 105. The second rack 104 is meshed and connected with the second passive gear 105, and the second rack 104 drives the second passive gear 105 to rotate to change the angle of the flower rack plate 9; the breeding base frame 8 is connected to the second motor 101, and the second motor 101 is connected to the second driving gear 102, and the second driving gear 102 is meshed and connected with the second rack 104. The second driving gear 102 is driven to rotate by the second motor 101, and then the power is transmitted to the second passive gear 105 through the second rack 104, thereby finally driving the flower rack plate 9 to swing.

[0031] The swinging design of the flower rack plate 9 has two advantages. First, during the lighting period, the angle of the flower rack plate 9 can be accurately adjusted according to the habits of different plants to control the degree of direct sunlight received by the plants, thereby creating a suitable lighting environment for various plants. Second, when the watering component 7 is taken to carry the flower pot 11, the flower rack plate 9 can be tilted to a suitable angle so that the inclined surface 901 where the flower pot 11 to be taken is located remains parallel to the clamp 704, which greatly facilitates the clamp 704 to grasp the flower pot 11. In addition, when taking the flower pot 11 located on the inclined surface 901 on the side away from the watering component 7, the inclined surface 901 close to the watering component 7 is tilted downward, which can effectively avoid other components on the watering component 7 and avoid collision.

[0032] The picking and watering component 7 includes a rotating power part 701, which is connected to a lifting power part 702, which is connected to a clamping power part 703, and which is connected to a clamping claw 704; the rotating power part 701 is also connected to a watering frame 705, which is provided with at least one watering nozzle 706, and a grabbing limit groove 110 is provided on the flower pot 11. The outer diameter of the lower edge of the grabbing limit groove 110 is larger than the inner diameter of the flower pot positioning hole 902. Therefore, when the flower pot 11 is placed on the flower pot positioning hole 902, the lower edge of the grabbing limit groove 110 is stuck above the flower pot positioning hole 902, ensuring that the flower pot 11 is firmly fixed on the flower pot positioning hole 902 and will not fall.

[0033] The base frame 4 of the three-dimensional mobile watering execution module B is slidably connected to the transverse moving part 5, and the telescopic part 6 is slidably and liftedly connected to the transverse moving part 5; the telescopic part 6 includes a telescopic base 601, and the first telescopic plate 603 forms a first-level sliding pair with the telescopic base 601 through a ball slider, and the second telescopic plate 606 is nested in the first telescopic plate 603 to form a second-level sliding pair; the three-dimensional mobile watering execution module B is slidably connected to the base frame 4 and the transverse moving part 5, and the telescopic part 6 is slidably and liftedly connected to the transverse moving part 5, so that the watering part 7 can be freely moved in multiple dimensions, the position can be flexibly adjusted, and it can accurately reach various positions of the plant cultivation module C for watering and carrying operations, thereby improving the coverage and accuracy of watering.

[0034] The telescopic base 601 is connected to the telescopic motor 602; the telescopic motor 602 drives the first telescopic plate 603 to slide via a first linkage mechanism. When the first telescopic plate 603 slides, the second telescopic plate 606 slides synchronously via a second linkage mechanism, ultimately achieving synchronized and uniform stacked telescopic motion of the first and second sliding pairs. Telescopic side plates 6024 are provided on both sides of the telescopic base 601. These plates are connected to a first pulley 60241; the second telescopic plate 606 is connected to a second pulley 6061. I-shaped slots are provided on both sides of the first telescopic plate 603; the first pulley 60241 slides in contact with the outer groove of the I-shaped slot, while the second pulley 6061 slides in contact with the inner groove of the I-shaped slot. This design ensures stability and smoothness during the telescopic process.

[0035] The first linkage mechanism includes a first sprocket 6021, a second sprocket 6022, a telescopic gear 6023 and a telescopic rack 6024 meshing with the telescopic gear 6023; the telescopic motor 602 is connected to the first sprocket 6021, the first sprocket 6021 is connected to the second sprocket 6022 through a chain, the second sprocket 6022 is coaxially connected to the telescopic gear 6023, and the telescopic rack 6024 is connected to the first telescopic plate 603. Through such a transmission structure, the power of the motor is transmitted to the first telescopic plate 603.

[0036] The second linkage mechanism includes a telescopic linkage component 605 and a tension spring 607; one end of the tension spring 607 is connected to the first telescopic plate 603, and the other end is connected to the second telescopic plate 606; the tension spring 607 enables the second telescopic plate 606 to have the power to reset, while further enhancing the stability and reliability of the linkage, ensuring the coordinated work between the various components during the telescopic process.

[0037] The telescopic linkage component 605 includes a third sprocket 6051 and a fourth sprocket 6052, and the third sprocket 6051 and the fourth sprocket 6052 are connected by a linkage chain 6053; the third sprocket 6051 is connected to the telescopic base 601, and the fourth sprocket 6052 is connected to the second telescopic plate 606. One end of the linkage chain 6053 is connected to the telescopic base 601, and the other end is connected to the second telescopic plate 606.

[0038] The telescopic component 6 achieves synchronous and uniform stacked telescopic motion through a two-stage sliding pair formed by the first telescopic plate 603 and the second telescopic plate 606. This design enables a large telescopic stroke within a limited space, effectively increasing the module's operating range while maintaining a compact structure and saving space. The first pulleys 60241 on either side of the telescopic base 601 and the second pulleys 6061 on the second telescopic plate 606 are respectively slidably connected to the inner and outer I-shaped grooves on either side of the first telescopic plate 603. This design provides good guidance and support for the telescopic motion, reducing shaking and deviation during motion, and ensuring the smoothness and reliability of the telescopic action. The first and second linkage mechanisms are cleverly designed. Through the coordination of transmission components such as sprockets, chains, gears, and racks, they can efficiently transmit the power of the telescopic motor 602 to the first and second telescopic plates 603, 606, achieving synchronous motion.

[0039] A watering method for a plant watering device based on a photovoltaic power generation system, characterized by comprising the following steps: S1: Photovoltaic tracking power generation module A has a photovoltaic panel angle adjustment power group 3 and a photovoltaic panel 2 rotatably connected to the photovoltaic frame 1. According to the angle of sunlight, the photovoltaic panel angle adjustment power group 3 adjusts the angle of the photovoltaic panel 2 accordingly to ensure that the photovoltaic panel 2 can always face the direction of sunlight.

[0040] S2: The electricity generated by the photovoltaic panel 2 is supplied to the photovoltaic panel angle adjustment power group 3, the three-dimensional mobile irrigation execution module B and the plant cultivation module C. It can also supply power to the water pump, which is used to pump water to irrigate the plants.

[0041] S3: The three-dimensional mobile watering execution module B includes a base frame 4, which is connected to a pick-up and watering component 7. The pick-up and watering component 7 can move in the X, Y, and Z axis directions relative to the base frame 4; the pick-up and watering component 7 includes a clamp 704, a watering nozzle 706, and a visual recognition unit. The pick-up and watering component 7 can move the flower pot 11 on the plant cultivation module C and water the plants in the flower pot 11.

[0042] S4: The visual recognition unit is equipped with a high-definition camera. Before taking the watering component 7 to water or move the flower pot 11, it will take a picture of the plant and compare it with the status of different growth stages of the plant preset in the system to achieve accurate identification of the plant growth status.

[0043] S5: The plant cultivation module C is provided with a flower stand angle adjustment power group 10. The flower stand angle adjustment power group 10 can accurately adjust the angle of the flower stand plate 9 according to the habits of different plants, and control the degree to which the plants receive direct sunlight.

[0044] The plant watering device and method based on the photovoltaic power generation system of the present invention, the watering method relies on the plant watering device based on the photovoltaic power generation system, the device is mainly composed of a photovoltaic tracking power generation module A, a three-dimensional mobile watering execution module B and a plant cultivation module C.

[0045] S1: Intelligent adjustment of photovoltaic panel angle The photovoltaic tracking power generation module A is the core part of the energy acquisition of the entire device. It has a photovoltaic panel angle adjustment power group 3 and a photovoltaic panel 2 that is rotatably connected to the photovoltaic frame 1. A photoreceptor is provided on the photovoltaic panel 2 to sense the angle of sunlight, and then the photovoltaic angle adjustment power group 3 is used to adjust the swing angle of the photovoltaic panel 2, so that the photovoltaic panel 2 can achieve intelligent light tracking and ensure that the photovoltaic panel 2 can always accurately face the direction of sunlight. In this way, the photovoltaic panel 2 can dynamically adjust its angle at different times of the day as the position of the sun changes, absorb the energy of sunlight to the greatest extent, and provide sufficient electricity for the stable operation of the entire device.

[0046] S2: Power distribution and water pump drive After fully absorbing sunlight energy, the photovoltaic panel 2 converts it into electrical energy through the photoelectric conversion effect. A portion of the electrical energy will be allocated to the photovoltaic panel angle adjustment power group 3 to maintain its continuous and stable operation, ensuring that the photovoltaic panel 2 can always maintain the optimal light reception angle. Another portion of the electrical energy will be supplied to the three-dimensional mobile irrigation execution module B to provide power for its movement in the X, Y, and Z axis directions and the operation of each component. At the same time, another portion of the electrical energy will be delivered to the plant cultivation module C to drive equipment such as the flower stand angle adjustment power group 10 to meet various needs during the plant cultivation process. In addition, a portion of the electrical energy will be allocated to the water pump, which will draw water from the water source and transport the water to the irrigation nozzle 706 of the irrigation component 7 through a pipe. In this way, a sufficient water source is provided for watering the plants.

[0047] S3: 3D mobile watering and handling operations The three-dimensional mobile watering execution module B is a key part for achieving precise watering and flower pot transportation. Its basic frame 4 serves as the supporting structure of the entire module and is connected to the picking and watering component 7. The picking and watering component 7 has excellent three-dimensional movement capabilities. It can be flexibly and accurately moved in the X, Y, and Z axis directions relative to the basic frame 4 through high-precision guide rails, screw transmissions and other mechanisms. The picking and watering component 7 is mainly composed of a clamp 704, a watering nozzle 705, and a visual recognition unit. When the plants need to be watered, the picking and watering component 7 will move to the designated flower pot 11 position in three-dimensional space, and the watering nozzle 706 will accurately control the water flow rate and time according to the water requirement of the plant, and water the plants in the flower pot 11 evenly and appropriately.

[0048] When the flower pot 11 needs to be moved, the watering component 7 will be moved above the flower pot 11. The clamping claw 704 will accurately locate the position of the flower pot 11 with the assistance of the visual recognition unit, and tightly clamp the flower pot 11 through precise mechanical control. Then, the watering component 7 will move again in the X, Y, and Z axis directions to move the flower pot 11 to the designated new position.

[0049] S4: Visual recognition and accurate judgment The visual recognition unit is equipped with a high-definition camera. Before watering the plant or relocating the flowerpot 11, the camera takes omnidirectional and multi-angle photos of the plant. The captured plant images are carefully compared with standard images of plants at different growth stages preset in the system. By comparing characteristics such as leaf color, shape, size, and growth status, the visual recognition unit can accurately determine the plant's current growth stage and health status.

[0050] For example, if the system detects yellowing or wilting of plant leaves, it may indicate a lack of water or pests and diseases. If the system detects excessive growth, it may need to reduce fertilizer. Based on these precise identification results, the system automatically adjusts watering amounts, fertilizer additions, and the need for pest and disease control measures, providing personalized and precise plant care.

[0051] S5: Precise control of the angle of the flower stand Plant cultivation module C precisely adjusts the angle of the trellis panels 9 to control the degree of direct sunlight exposure to plants. For example, for shade-loving plants, the trellis panels 9 can be adjusted to a lower angle to reduce the duration and intensity of direct sunlight exposure; while for sun-loving plants, the trellis panels 9 can be adjusted to a higher angle to increase the duration and intensity of direct sunlight exposure. This creates the optimal growing environment for each plant, promoting healthy plant growth.

[0052] The present invention provides electric energy for the operation of the device through the photovoltaic tracking power generation module A. At the same time, the position of the photovoltaic panel 2 can also provide sunshade protection for the plants to prevent them from being damaged by direct high temperature. The three-dimensional mobile irrigation execution module B is set so that the position of the plant can be higher, thereby improving the space utilization rate of the plant cultivation module C, fully tapping the potential of the planting space, and can quantitatively water the plants and detect the growth status of the plants in real time, providing more refined cultivation for the plants. The plant cultivation module C can control the degree of direct sunlight received by the plants by precisely adjusting the angle of the flower rack board 9, thereby creating the most suitable growth environment for different plants and promoting the healthy growth of the plants. In short, through the setting of the photovoltaic tracking power generation module A, the three-dimensional mobile irrigation execution module B, and the plant cultivation module C, not only can a better living space and environment be provided for the plants, but also the sunlight resources can be fully utilized to achieve energy saving and environmental protection, and the growth of the plants can be intelligently monitored so that the plants can achieve optimal development.
