[0040] In the technical solution provided by this invention, when the temperature and humidity sensor detects that the planting area in the irrigation zone is too dry, the nutrient solution in the storage tank will enter the corresponding branch pipe and finally irrigate the planting area through the irrigation holes on the branch pipe, thereby increasing the humidity of the planting area. When the temperature and humidity sensor detects that the humidity has reached a suitable value, the corresponding branch pipe will be closed, preventing the nutrient solution from entering the planting area, thus achieving the effect of saving water. Therefore, the plant cultivation drip irrigation device provided by this application can control the connection status of the corresponding branch pipe according to the temperature and humidity of the planting area, thereby automatically controlling the irrigation amount of different irrigation areas, thus avoiding the negative impact of over-irrigation or under-irrigation on plant growth.

[0054] Watering is a crucial aspect of garden plant cultivation. To ensure healthy plant growth, careful planning and management of the irrigation system are essential. This includes selecting suitable water sources, such as groundwater, river water, or rainwater harvesting systems, and adjusting the frequency and amount of watering according to the specific needs of the plants and weather conditions. Furthermore, modern technologies widely utilize water-saving techniques such as drip irrigation and sprinkler irrigation to improve water resource utilization efficiency and reduce waste. However, when irrigating large planting areas, the varying soil moisture across different areas can lead to over-irrigation or under-irrigation during drip irrigation, resulting in water waste or plant drought.
[0055] To address this technical problem, the present invention provides a drip irrigation device for plant cultivation, which solves the problem of excessive or insufficient irrigation caused by existing devices, resulting in waste of water resources or drought in plants.
[0056] Please see Figure 1The plant cultivation drip irrigation device 100 includes a storage tank 1, an inlet pipe, an irrigation device 2, and a detection device. The storage tank 1 has an inner cavity 11 for storing nutrient solution. The upper end face of the storage tank 1 is provided with a first inlet hole 12 and a water inlet hole 13. The outer side wall of the storage tank 1 is provided with a discharge hole 14. The end of the inlet pipe extends into the inner cavity 11 from the first inlet hole 12. The irrigation device 2 includes a main pipe 21 and a plurality of branch pipes 22 connected to the main pipe 21. The main pipe 21 is connected to the discharge hole 14. Each branch pipe 22 is provided with an irrigation hole 221 for transporting the nutrient solution in the inner cavity 11 to the irrigation area. The detection device includes a temperature and humidity sensor 3 installed on the branch pipe 22 for detecting the temperature and humidity of the irrigation area.
[0057] In the technical solution provided by this invention, when the temperature and humidity sensor 3 detects that the planting area in the irrigation zone is too dry, the nutrient solution in the storage tank 1 will enter the corresponding branch pipe 22, and finally irrigate the planting area through the irrigation hole 221 on the branch pipe 22, thereby increasing the humidity of the planting area. When the temperature and humidity sensor 3 detects that the humidity has reached a suitable value, the corresponding branch pipe 22 will be closed, preventing the nutrient solution from entering the planting area, thus achieving the effect of saving water. Therefore, the plant cultivation drip irrigation device 100 provided by this application can control the connection status of the corresponding branch pipe 22 according to the temperature and humidity of the planting area, thereby automatically controlling the irrigation amount of different irrigation areas, thus avoiding the negative impact of over-irrigation or under-irrigation on plant growth.
[0058] It should be noted that the water inlet 13 is used to deliver water into the storage tank 1, and the first liquid inlet 12 is used to deliver nutrient solution into the storage tank 1. In this way, the nutrient solution and water mix in the storage tank 1 to obtain a nutrient solution for irrigating the plantation. Alternatively, the end of the liquid inlet pipe can extend into the inner cavity 11 from the first liquid inlet 12, or a water inlet pipe can be used to deliver water into the inner cavity 11 through the water inlet 13.
[0059] It is understood that multiple branch pipes 22 can be located on the same side of the main pipe 21 or distributed on opposite sides of the main pipe 21. Furthermore, a water pump 23 can be installed on the main pipe 21 to provide more sufficient power to the irrigation device 2, and solenoid valves can be installed on the main pipe 21 and each branch pipe 22 to control the flow of the pipes.
[0060] The dimensions of the main pipe 21, branch pipes 22, and storage tank 1 in this application can be determined according to actual conditions. The branch pipes 22 are distributed across the planting area, and a conical temperature and humidity sensor 3 is inserted into the ground. Water and nutrient solution are then injected into the storage tank 1 through the water inlet 13 and the first liquid inlet 12. When the temperature and humidity sensor 3 detects that the ground is too dry, the water pump 23 is activated and the solenoid valve is opened. At this time, the water in the storage tank 1 enters the main pipe 21, then the branch pipes 22, and finally flows out of the branch pipes 22. The irrigation holes 221 on channel 22 drip water onto the planting area, increasing the humidity. When the temperature and humidity sensor 3 detects that the humidity has reached a suitable value, it can close the solenoid valve on the corresponding branch channel 22 to prevent water from entering the planting area. When all the values detected by the temperature and humidity sensors 3 meet the requirements, the water pump 23 will shut off. The device can automatically drip irrigate the planting area and can also control the automatic opening and closing of the branch channel 22 according to the humidity of the planting area to save water.
[0061] In some embodiments of the present invention, please refer to the relevant literature. Figure 2 The plant cultivation drip irrigation device 100 also includes a stirring device 4, which is located in the inner cavity 11 of the storage tank 1. The stirring device 4 includes a rotating shaft 41 and multiple sets of blades 42. The rotating shaft 41 is coaxially arranged with the storage tank 1 and rotatably installed along an axis extending vertically. The multiple sets of blades 42 are located on the outer wall of the rotating shaft 41 and are arranged along the axial direction of the rotating shaft 41. When water and nutrient solution are added to the storage tank 1, the rotating shaft 41 can be controlled to rotate. At this time, the blades 42 will stir and mix the water and nutrient solution in the storage tank 1 to improve the irrigation effect of the planting area.
[0062] It should be noted that the stirring device 4 also includes a motor to provide power for the rotation of the shaft 41. The motor can be installed outside the storage tank 1 or inside the storage tank 1. When the motor is installed inside the storage tank 1, a waterproof protective shell can be used to protect the motor.
[0063] Furthermore, please refer to the following: Figure 3 and Figure 4The rotating shaft 41 has a cavity 411 inside, and the side wall of the rotating shaft 41 has multiple water outlet holes 412 communicating with the cavity 411. The plant cultivation drip irrigation device 100 also includes a mixing device 5, which includes a mixing component 51 and a blocking component 52. The mixing component 51 has an inner side wall 511 close to the rotating shaft 41 and an outer side wall 512 away from the rotating shaft 41. The mixing component 51 is disposed on the outer periphery of the rotating shaft 41 and fixedly connected to the bottom of the inner cavity 11. The interior of the mixing component 51 is hollow to form a receiving cavity 513. The inner side wall 511 of the mixing component 51 is partially connected to the side wall of the rotating shaft 41. A mixing hole 514 is provided at the connection to connect the cavity 411 and the receiving cavity 513; the barrier 52 is movably sealed in the receiving cavity 513, and the barrier 52 divides the receiving cavity 513 into a gas receiving cavity and a liquid receiving cavity, wherein the liquid receiving cavity is located near the rotating shaft 41 and is used to store nutrient solution, and the gas receiving cavity is used to connect with external air. The barrier 52 has a radial sliding stroke along the rotating shaft 41 to adjust the pressure in the gas receiving cavity and the liquid receiving cavity, so that the nutrient solution flows in the liquid receiving cavity, the rotating shaft cavity 411 and the inner cavity 11 of the storage tank.
[0064] It should be noted that the barrier 52 is slidably sealed to the inner wall of the mixing component 51, so that there is no flow between the gas chamber and the liquid chamber. When the barrier 52 moves away from the rotating shaft 41, it compresses the gas chamber space and draws more nutrient solution into the liquid chamber; when the barrier 52 moves away from the rotating shaft 41, it sprays the nutrient solution from the liquid chamber through the inner cavity 11 and the water outlet 412 on the side wall of the rotating shaft 41, causing the water in the storage tank 1 to fluctuate, thereby improving the mixing efficiency between water and nutrient solution.
[0065] Furthermore, the mixing device 5 also includes an air inlet pipe 53, one end of which is connected to the gas containing chamber, and the other end extends out of the barrel to connect with external air. The other end of the air inlet pipe 53 can extend from the upper end face of the storage tank 1 or from the side wall of the storage tank 1. The air inlet pipe 53 can better maintain the pressure balance in the containing chamber. When the blocking member 52 moves away from the rotating shaft 41, the blocking member 52 compresses the space of the gas containing chamber and makes the liquid containing chamber 513 have a larger space, and the air in the gas containing chamber is discharged from the air inlet pipe 53; when the blocking member 52 moves away from the rotating shaft 41, the blocking member 52 draws external air into the gas containing chamber from the air inlet pipe 53 and compresses the space in the liquid containing chamber 513 to spray the nutrient solution from the water outlet 412 on the side wall of the rotating shaft 41.
[0066] The mixing device 5 further includes a driving assembly for driving the blocking member 52 to slide. The driving assembly includes a first magnetic block 54 and a first elastic member 55. The first magnetic block 54 is disposed on the outer side wall of the rotating shaft 41 and is arranged radially on the rotating shaft 41 corresponding to the blocking member 52. The first magnetic block 54 is offset from the mixing hole 514 in the vertical direction. The blocking member 52 is provided with a first magnetic element so that when the first magnetic block 54 rotates to be radially aligned with the blocking member 52, the blocking member 52 moves toward the first magnetic block 54. The two ends of the first elastic member 55 are respectively connected to the outer side wall 512 of the mixing member 51 and the blocking member 52 to reset the blocking member 52.
[0067] As the shaft 41 rotates, the first magnetic block 54 intermittently passes by the barrier 52. When the first magnetic block 54 approaches the barrier 52, the barrier 52 moves toward the first magnetic block 54, that is, the barrier 52 moves toward the shaft 41, and the first elastic member 55 is stretched. When the first magnetic block 54 moves away from the barrier 52, the barrier 52 moves away from the shaft 41 under the pulling force of the first elastic member 55. Thus, during the rotation of the shaft 41, the barrier 52 is cyclically attracted by the first magnetic block 54 and moves back and forth, thereby continuously pushing the water in the liquid receiving cavity and causing the water in the storage tank 1 to continuously fluctuate. With this configuration, the barrier 52 can be repeatedly moved by the rotation of the shaft 41 without the need for other power mechanisms.
[0068] It should be noted that the first elastic element 55 can also be disposed between the inner wall 511 of the mixing component 51 and the barrier element 52. However, this arrangement has two drawbacks: firstly, it requires the use of a compressible elastic element such as a spring, which imposes more restrictions; secondly, the lifespan of the elastic element in aqueous solution is shorter than that in air. Disposing the first elastic element 55 between the outer wall 512 of the mixing component 51 and the barrier element 52 not only provides more options for the elastic element but also increases its lifespan. It is understood that in this application, the first elastic element is a spring or an elastic cord.
[0069] It should be noted that in some other embodiments, the barrier 52 may be made of a magnetic material to form the first magnetic element. This application does not impose any limitations on this. Furthermore, the first magnetic block 54 may protrude from the outer wall of the rotating shaft 41, while in some other embodiments, the outer wall of the rotating shaft 41 is recessed towards the center of the rotating shaft 41 near the connecting groove to form a first groove, and the first magnetic block 54 is disposed within the first groove. This arrangement does not occupy additional space, and the surface area of the first magnetic block 54 exposed in the nutrient solution is smaller, which helps to extend the service life of the device.
[0070] Furthermore, the bottom of the rotating shaft 41 is provided with a balance hole 413 communicating with the cavity 411. The plant cultivation drip irrigation device 100 also includes a first monitoring structure 6, which includes a support rod 61, a float ring 62, and a sensor. The support rod 61 is disposed in the inner cavity 11 along the vertical direction, and one end is fixedly connected to the bottom wall of the inner cavity 11. The float ring 62 is sleeved on the outer surface of the support rod 61 and can slide along the support rod 61. The sensor has two sensing ends, which are respectively disposed at the bottom of the float ring 62 and the bottom wall of the inner cavity 11, so as to issue a warning information when the float ring 62 slides to the point where the two sensing ends contact. With the presence of the balance hole 413, when the liquid level in the inner cavity 11 of the storage tank 1 decreases, the liquid level in the cavity 411 of the rotating shaft 41 will also decrease accordingly, and the float ring 62 will also move downward with the liquid level. When the water level in the storage tank 1 drops to its lowest point, the water in the cavity 411 of the rotating shaft 41 will be drained through the balance hole 413. At this time, the sensing end on the float ring 62 will contact the sensing end on the bottom wall of the inner cavity 11 and trigger an alarm. The alarm information can be transmitted to the staff's mobile phone via an APP to remind the staff to add water to the storage tank 1 in time.
[0071] In some embodiments, the storage bin 1 includes a sealed body and a lid, the lid being sealed over the opening of the bin body, the lid having a first liquid inlet 12 and a water inlet 13, and the outer wall of the bin body having a discharge outlet 14. The bin body and lid are detachable to allow for cleaning and maintenance of the internal components of the storage bin.
[0072] Please refer to the following: Figure 5 The plant cultivation drip irrigation device 100 further includes a liquid storage component 7, which includes a liquid storage box 71, a pressure plate 72, and a connecting rod 73. The liquid storage box 71 has a cavity for storing nutrient solution. The liquid storage box 71 includes a side plate 711, a top plate, and a bottom plate. The top plate is fixedly connected to the lower side of the cover. The bottom plate is provided with a plurality of first liquid outlet holes 713. The side plate 711 is provided with a second liquid inlet hole. The end of the liquid inlet pipe passes through the first liquid inlet hole 12 and the second liquid inlet hole and extends into the liquid storage box 71. The pressure plate 72 is movably disposed in the liquid storage box 71 to drive the nutrient solution to be output downward from the first liquid outlet hole 713. The connecting rod 73 has a vertical stroke. The cover is provided with a through hole corresponding to the liquid storage box 71. One end of the connecting rod 73 is fixedly connected to the pressure plate 72, and the other end extends out of the cover from the through hole. With this configuration, the nutrient solution can be injected into the storage box 71 through the inlet pipe, and then the nutrient solution flows evenly into the storage tank 1 from multiple first outlet holes 713 to mix with the water in the storage tank 1, thereby improving the uniformity of the mixing of the nutrient solution and water.
[0073] It should be noted that the pressure plate 72 is sealed to the side plate 711 during its vertical movement, and a third elastic element is fixedly connected between the top surface of the pressure plate 72 and the top plate of the liquid storage box 71. When nutrient solution is added to the liquid storage box 71 or the connecting rod 73 is manually lifted upwards, the pressure plate 72 moves upwards and compresses the third elastic element. When releasing the nutrient solution, the pressure plate 72, under the rebound force of the third elastic element, allows the liquid to be sprayed out from the first outlet hole 713 with greater pressure, making the nutrient solution diffuse more widely in the water, thereby improving the mixing efficiency of the nutrient solution and water. When it is necessary to reset the pressure plate 72, the connecting rod 73 can be lifted upwards, causing the connecting rod 73 to drive the pressure plate 72 to reset. The third elastic element can be a spring.
[0074] Furthermore, the base plate includes a first base plate 712 and a second base plate 714 arranged vertically, which together form a discharge cavity. The liquid storage assembly 7 also includes a liquid control plate 74, which is horizontally slidable in the discharge cavity. The thickness of the liquid control plate 74 is adapted to the height of the discharge cavity to ensure good sealing performance between the liquid control plate 74 and the first and second base plates 712 in the liquid storage state. The liquid control plate 74 has multiple second discharge holes 741 corresponding to the first discharge hole 713. During its movement, the liquid control plate 74 has a discharge state in which the second discharge holes 741 are connected to the first discharge hole 713 in the vertical direction, and a liquid storage state in which the second discharge holes 741 are staggered from the first discharge hole 713 in the vertical direction. With this configuration, by controlling the sliding of the liquid control plate 74, the flow of liquid in the liquid storage box 71 into the storage tank 1 can be controlled. When the storage box 71 does not need to release the nutrient solution into the storage tank 1, the control plate 74 is in its initial state, at which time the second outlet hole 741 and the first outlet hole 713 are offset vertically. When the storage box 71 needs to release the nutrient solution into the storage tank 1, the control plate 74 moves to the dispensing state, at which time the second outlet hole 741 and the first outlet hole 713 are connected vertically to release the nutrient solution into the storage tank 1. It can be understood that the control plate 74 is sealed between itself and the first bottom plate 712 and the second bottom plate 714 in the dispensing state.
[0075] In some embodiments, the movement of the liquid control plate 74 is achieved by a sliding assembly. In some other embodiments of this application, one end of the liquid control plate 74 is provided with a second magnetic element 75; the liquid storage assembly 7 further includes a second magnetic block 76, a connecting rod structure 77, and a second elastic element 78: the second magnetic block 76 repels the second magnetic element 75, the second magnetic block 76 is disposed in the inner cavity 11 of the storage tank 1, and is arranged horizontally corresponding to the liquid control plate 74; the connecting rod structure 77 is fixedly connected to the second magnetic block 76 and the rotating shaft 41, so that the liquid control plate 74 is moved by a sliding assembly. The second magnetic block 76 rotates with the rotating shaft 41; the two ends of the second elastic member 78 are respectively connected to the liquid control plate 74 and the side plate 711 of the liquid storage box 71; wherein, when the second magnetic block 76 rotates to approach the second magnetic member 75, it pushes the second magnetic member 75 to move away from the second magnetic block 76, until the liquid control plate 74 is in the liquid discharge state; when the second magnetic block 76 rotates to move away from the second magnetic member 75, the second elastic member 78 pushes the liquid control plate 74 to reset, until the liquid control plate 74 is in the liquid storage state. With this configuration, the magnetic force between the second magnetic block 76 and the second elastic member 78 serves as the driving force for the liquid control plate 74, achieving the movement and reset of the liquid control plate 74 without the need for other power devices or cooperating components. The second elastic member 78 can be configured as a spring.
[0076] In some other embodiments, the second magnetic block 76 and the second magnetic element 75 can be configured to be magnetically attracted. When the second magnetic block 76 rotates to approach the second magnetic element 75, the liquid control plate 74 is in a liquid storage state, and the second elastic element 78 is compressed. When the second magnetic block 76 rotates to move away from the second magnetic element 75, the second elastic element 78 resets to push the liquid control plate 74 to move, so that the liquid control plate 74 is in a liquid discharge state.
[0077] Furthermore, in some embodiments, please refer to [the relevant documentation]. Figure 6The liquid storage assembly 7 further includes a second monitoring structure 8, which includes a flexible ring 81 and a fixed ring 82. The flexible ring 81 is fixed above the cover and allows the connecting rod 73 to pass through it. The fixed ring 82 is located above the flexible ring 81 and is fixedly arranged around the connecting rod 73. The flexible ring 81 is a hollow structure, and its outer wall has multiple air holes. The air holes are closed when the flexible ring 81 is in its natural state and open when the flexible ring 81 is deformed by external force. The flexible ring 81 is filled with colored gas, which is released to provide an early warning when the fixed ring 82 compresses the flexible ring 81. When the liquid in the storage box 71 decreases, the pressure plate 72 will drive the connecting rod 73 to move downward. When the nutrient solution is used up or the remaining amount is small, the fixing ring 82 on the connecting rod 73 will squeeze the flexible ring 81, causing the vent to be opened. At this time, red gas will be discharged from the flexible ring 81 to warn the staff that the nutrient solution in the storage box 71 is insufficient.
[0078] In one embodiment of this application, the nutrient solution can be injected into the storage box 71 through the inlet pipe, and then flow evenly into the storage tank 1 from the first outlet hole 713 and the second outlet hole 741 to mix with the water in the storage tank to obtain the nutrient solution, which can improve the uniformity of the mixing of the nutrient solution and water. Alternatively, the first outlet hole 713 can be sealed with the liquid control plate 74 before the nutrient solution is injected into the storage box 71 for storage. When the nutrient solution needs to be used, the rotating shaft 41 can be driven to rotate, so that the second magnet 76 is away from the end of the liquid control plate 74 where the first magnetic element is located, so that the positions of the first outlet hole 713 and the second outlet hole 741 are aligned. At this time, the nutrient solution will fall into the storage tank 1 from the first outlet hole 713 and the second outlet hole 741, thus realizing the storage of nutrient solution for use at any time.
[0079] When water and nutrient solution are added to the storage tank 1, the motor can be started to drive the rotating shaft 41 to rotate. At this time, the blades 42 will stir and mix the water and nutrient solution in the storage tank 1 to enhance the irrigation effect on the planting area. During this process, the nutrient solution in the storage tank 1 will enter the rotating shaft 41 from the water outlet 412 and enter the mixing component 51 through the mixing hole 514. During the movement of the barrier 52, the nutrient solution in the mixing component 51 will flow out of the cavity 411 of the rotating shaft 41 from the mixing hole 514 and the water outlet 412, thereby improving the mixing efficiency between water and nutrient solution.
[0080] By distributing branch pipes 22 across the planting area and inserting conical temperature and humidity sensors 3 into the ground, water and nutrient solution are injected into the storage tank 1. When the temperature and humidity sensors 3 detect that the ground is too dry, the water pump 23 and solenoid valve are activated. At this time, the water in the storage tank 1 enters the main pipe 21, then enters the branch pipes 22, and finally drips from the irrigation holes 221 on the branch pipes 22 onto the planting area, increasing the humidity of the planting area. When the temperature and humidity sensors 3 detect that the humidity has reached a suitable value, the solenoid valve on the corresponding branch pipe 22 can be closed to prevent water from entering the planting area. When all the values detected by the temperature and humidity sensors 3 have reached the required values, the water pump 23 and the solenoid valve on the main pipe 21 will close. Through the above mechanism, the effect of automatic drip irrigation of the planting area can be achieved. At the same time, the automatic opening and closing of the branch pipes 22 can be controlled according to the humidity of the planting area to achieve the effect of water conservation.
