Description

Technical Field

[0001] This utility model relates to the technical field of irrigation devices, specifically an unattended agricultural irrigation device. Background Technology

[0002] Agriculture is an industry that uses the growth and development patterns of plants and animals to produce products through artificial cultivation. Agriculture belongs to the primary industry, and the science that studies agriculture is agronomy. When planting crops, it is necessary to irrigate them to replenish their water supply. Irrigation devices are needed to irrigate crops in agricultural fields.

[0003] The Chinese patent announcement CN221863952U discloses an agricultural water-saving irrigation device. Its key technical features include a connecting pipe, a housing, and a water pipe. A third solenoid valve is fixedly connected to the outside of the water pipe inside the housing. A nozzle is fixedly connected to the top of the water pipe. A connecting pipe is fixedly connected to the inside of the housing at the top of the water pipe. A lower spray plate is fixedly connected to the outside of the connecting pipe. A guide tube is fixedly connected to the inside of the housing at the top of the connecting pipe. A first solenoid valve is fixedly connected to the outside of the guide tube at the top of the second solenoid valve. An upper spray plate is fixedly connected to the outside of the guide tube.

[0004] In the above scheme, by controlling the opening of the third solenoid valve, water is introduced into the interior of the nozzle through the water pipe, and then the water is atomized and sprayed out through the nozzle to achieve a small amount of irrigation and supplemental water for the planting area. This results in the following disadvantages: when the water pipe is blocked or burst in the absence of human intervention, the irrigation function cannot be stopped, which leads to a reduction in the safety and reliability of the irrigation system. Utility Model Content

[0005] The purpose of this invention is to provide an unattended agricultural irrigation device to solve the problem that the device cannot stop the irrigation function when the water pipe is blocked or burst when it is unattended, which leads to a decrease in the safety and reliability of the irrigation system.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: an unattended agricultural irrigation device, comprising a water pipe, the water pipe being disposed on the front side of a water tank, a water pump being fixed on the front side of the water tank, a delivery pipe being fixedly connected between the input end of the water pump and the water tank, the output end of the water pump being connected to the water pipe, a plurality of nozzles being fixedly connected to the top surface of the water pipe, a detection hole being opened on the top surface of the water pipe, a connecting cylinder being fixed on the top surface of the water pipe, mounting grooves being opened on the left and right sides of the inner wall of the connecting cylinder, two pistons being disposed inside the connecting cylinder, a connecting rod being fixed between the two pistons, support plates being fixed on the left and right sides of the connecting rod, springs being fixed between the top and bottom surfaces of the two support plates and the two mounting grooves, limit switches being fixed on the top and bottom surfaces inside the two mounting grooves, top rods being fixed on the top and bottom surfaces of the two support plates, a solenoid valve being disposed on the water pipe, a PLC controller being fixed on the right side of the water tank, and the water pump, limit switches, and solenoid valve being electrically connected to the PLC controller.

[0007] Preferably, a buzzer is fixed to the top surface of the water tank, and a 4G module is fixed to the top surface of the water tank. Both the buzzer and the 4G module are electrically connected to the PLC controller.

[0008] Preferably, a liquid level sensor is fixedly connected to the right side of the outer wall of the water tank, and the liquid level sensor is electrically connected to the PLC controller.

[0009] Preferably, a warning light is fixed on the top surface of the water tank, the warning light is electrically connected to the PLC controller, and the warning light integrates a red light, a yellow light, and a green light.

[0010] Preferably, a limiting hole is provided on the top surface of the connecting cylinder, and a limiting rod is fixed on the top surface of the piston above, the limiting rod being slidably inserted into the limiting hole.

[0011] Preferably, the top surface of the water tank is connected to and fixed with a connecting pipe, and the outer wall of the water pipe is fixed with several supports.

[0012] Compared with existing technologies, an unattended agricultural irrigation device that adopts the above-mentioned technical solution has the following beneficial effects:

[0013] 1. In use, through the coordinated action of water pipes, water tanks, water pumps, delivery pipes, nozzles, detection holes, connecting cylinders, mounting grooves, pistons, connecting rods, support plates, springs, limit switches, push rods, solenoid valves, and PLC controllers, the system can automatically stop irrigation when the water pipes become blocked or burst in unattended conditions, thus improving the safety and reliability of the irrigation system and reducing losses caused by malfunctions.

[0014] Second, during use, the buzzer's on-site alarm sound can immediately attract the attention of those nearby, enabling them to take swift action. The 4G module's remote information transmission function allows staff to be aware of any malfunctions in the irrigation system even when they are not on-site, facilitating timely dispatch of maintenance personnel. When the water level in the tank is too low, the level sensor immediately detects this and quickly sends a "no water" signal to the PLC controller. Upon receiving the signal, the PLC controller rapidly activates the buzzer and 4G module, causing the buzzer to emit a specific alarm sound to alert on-site personnel that the water level in the tank is insufficient.

[0015] Thirdly, during use, the different displays of red, yellow, and green lights on the warning lights allow staff to quickly and accurately identify the situation and take appropriate measures in a timely manner. This intuitive information transmission method improves the efficiency and accuracy of fault handling. The limit rod slides within the limit hole, limiting the piston and connecting rod to prevent deviation or shaking during vertical movement, thus improving stability. Staff can simply inject water into the water tank through the connecting pipe, while the bracket provides stable support for the water pipe, maintaining its stability and ensuring a stable water spray from the nozzle.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-3As shown, an unattended agricultural irrigation device includes a water pipe 1, which is located in front of a water tank 2. A water pump 3 is fixed to the front of the water tank 2. A delivery pipe 4 is fixedly connected between the input end of the water pump 3 and the water tank 2. The output end of the water pump 3 is connected to the water pipe 1. Several nozzles 5 are fixedly connected to the top surface of the water pipe 1. A detection hole 6 is opened on the top surface of the water pipe 1. A connecting cylinder 7 is fixed to the top surface of the water pipe 1. Mounting grooves 8 are opened on the left and right sides of the inner wall of the connecting cylinder 7. Two pistons 9 are installed inside the connecting cylinder 7, and a connecting rod 1 is fixed between the two pistons 9. 0. Support plates 11 are fixed on the left and right sides of the connecting rod 10. Springs 12 are fixed between the top and bottom surfaces of the two support plates 11 and the two mounting slots 8. Limit switches 13 are fixed on the top and bottom surfaces inside the two mounting slots 8. Top rods 14 are fixed on the top and bottom surfaces of the two support plates 11. Solenoid valves 15 are installed on the water pipe 1. PLC controller 16 is fixed on the right side of the water tank 2. Water pump 3, limit switches 13 and solenoid valve 15 are all electrically connected to PLC controller 16. The model of PLC controller 16 is Siemens S7-200.

[0023] In use, the staff only needs to start the water pump 3 and the solenoid valve 15 through the PLC controller 16. At this time, the water in the water tank 2 is accurately introduced into the water pipe 1 through the delivery pipe 4 under the action of the water pump 3, and then sprayed out through several nozzles 5 distributed on the top surface of the water pipe 1 to complete the water spraying irrigation operation.

[0024] When water pipe 1 becomes blocked, the internal pressure of water pipe 1 increases sharply. This pressure change is quickly transmitted to the connecting cylinder 7 through the detection hole 6. Under the action of pressure, piston 9, connecting rod 10 and support plate 11 move upward, overcoming the elastic force of spring 12. As support plate 11 moves, the top rod 14 fixed above it moves upward, contacting and triggering the two limit switches 13 above. After the limit switches 13 are triggered, the blockage information is immediately and accurately transmitted to PLC controller 16. PLC controller 16 responds quickly and automatically shuts down water pump 3 and solenoid valve 15, effectively avoiding water waste and equipment damage caused by blockage.

[0025] When water pipe 1 bursts, the pressure in water pipe 1 drops sharply. This causes a downward suction force on piston 9 through detection hole 6, which drives connecting rod 10 and support plate 11 to move downwards. This also overcomes the elastic force of spring 12. At this time, the top rod 14 fixed below support plate 11 moves downwards, contacts and triggers the two limit switches 13 below. The limit switches 13 transmit the burst information to PLC controller 16 in a timely manner. PLC controller 16 also automatically shuts down water pump 3 and solenoid valve 15 to prevent excessive water loss and other potential problems.

[0026] Through the coordinated action of water pipe 1, water tank 2, water pump 3, delivery pipe 4, nozzle 5, detection hole 6, connecting cylinder 7, mounting groove 8, piston 9, connecting rod 10, support plate 11, spring 12, limit switch 13, push rod 14, solenoid valve 15 and PLC controller 16, the irrigation system can automatically stop irrigation when water pipe 1 is blocked or burst in unattended conditions, which improves the safety and reliability of the irrigation system and reduces losses caused by failure.

[0027] like Figure 1 and Figure 2 As shown, a buzzer 17 is fixed on the top surface of water tank 2, and a 4G module 18 is fixed on the top surface of water tank 2. Both the buzzer 17 and the 4G module 18 are electrically connected to the PLC controller 16.

[0028] During use, when a blockage or burst occurs in water pipe 1, limit switch 13 quickly transmits this critical information to PLC controller 16. PLC controller 16 immediately starts the control program and simultaneously controls buzzer 17 to emit a loud alarm sound, alerting nearby staff to the abnormal situation. At the same time, 4G module 18 is also activated, quickly sending detailed information about the blockage or burst to a preset mobile phone or other terminal device via wireless network. The on-site alarm sound of buzzer 17 can attract the attention of surrounding personnel immediately, enabling them to take swift action. The remote information transmission function of 4G module 18 allows staff to understand the malfunction of the irrigation device in a timely manner even when they are not on-site, and to promptly arrange for maintenance personnel to handle the situation.

[0029] like Figure 1 and Figure 2 As shown, a liquid level sensor 19 is fixedly connected to the right side of the outer wall of the water tank 2. The liquid level sensor 19 is electrically connected to the PLC controller 16. A warning light 20 is fixedly connected to the top surface of the water tank 2. The warning light 20 is electrically connected to the PLC controller 16. The warning light 20 integrates a red light 21, a yellow light 22, and a green light 23.

[0030] During use, the level sensor 19 can detect changes in the water level in the water tank 2 in real time and continuously and accurately transmit the water level information in the water tank 2 to the PLC controller 16. When the water level in the water tank 2 is too low, the level sensor 19 immediately senses this situation and quickly sends a "no water" signal to the PLC controller 16. After receiving the signal, the PLC controller 16 quickly controls the buzzer 17 and the 4G module 18. The buzzer 17 emits a specific alarm sound to remind on-site personnel that the water level in the water tank 2 is insufficient. At the same time, the 4G module 18 sends the "no water" alarm information to the terminal devices of relevant personnel, which can promptly remind staff to replenish the water source and avoid irrigation interruption due to the lack of water in the water tank 2. When a burst water pipe 1 is detected, the PLC controller 16 quickly activates the red light 21 on the warning light 20. The red light 21 flashes, clearly conveying the emergency information of the burst water pipe 1 to the staff, reminding them to take immediate measures, such as checking the location of the burst pipe, to prevent further waste of water resources and other potential problems. When a blockage is detected in water pipe 1, the PLC controller 16 activates the yellow light 22 on the warning light 20. The yellow light 22 illuminates, indicating to the staff that water pipe 1 is blocked and that components such as the water pump 3 and the nozzle 5 need to be checked and the blockage cleared promptly. When the water level in water tank 2 is detected to be too low, the PLC controller 16 activates the green light 23 on the warning light 20. The illumination of the green light 23 clearly informs the staff that water tank 2 needs to be replenished so that water can be added in a timely manner to ensure the continuous operation of irrigation. Through the different displays of the red light 21, yellow light 22 and green light 23 on the warning light 20, the staff can quickly and accurately distinguish the situation and take appropriate measures in a timely manner. This intuitive information transmission method improves the efficiency and accuracy of fault handling.

[0031] like Figures 1-4 As shown, a limiting hole 24 is opened on the top surface of the connecting cylinder 7, and a limiting rod 25 is fixed on the top surface of the piston 9 above. The limiting rod 25 is slidably inserted into the limiting hole 24. A connecting pipe 26 is fixedly connected to the top surface of the water tank 2, and several brackets 27 are fixed on the outer wall of the water pipe 1.

[0032] During use, when the piston 9 and connecting rod 10 move up and down within the connecting cylinder 7, the limiting rod 25 slides into the limiting hole 24, limiting the piston 9 and connecting rod 10 and ensuring that they do not shift or shake during the up and down movement, thus improving stability. Operators can inject water into the water tank 2 simply through the connecting pipe 26, while the bracket 27 provides stable support for the water pipe 1, maintaining its stability and ensuring that water can be sprayed steadily from the nozzle 5.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
