[0012] Preferably, the flow collector is connected to four air guide pipes, the air guide pipes are installed obliquely upwards, the four solenoid valves, nozzles and air guide pipes are arranged in a circle relative to the axis of the flow collector, the air guide pipes are located directly above the solenoid valves, and the second level gauge, auxiliary water pump, third wireless transceiver, four solenoid valves and four humidity sensors are electrically connected.

[0013] Preferably, the wireless transmission range of the third wireless transceiver is slightly larger than the distance between the two irrigation center mechanisms, and each pair of adjacent third wireless transceivers is wirelessly connected. The wireless transmission range of the second wireless transceiver is slightly larger than the distance between the two main water valves, and each pair of adjacent auxiliary water valves is wirelessly connected. The main water pump is electrically connected to the first wireless transceiver. The wireless signals of the multiple third wireless transceivers are transmitted linearly along the axis of the water conveyance trough, and the wireless signals of the multiple second wireless transceivers are transmitted linearly along the axis of the main water conveyance pipe.

[0014] Preferably, the main water pump and multiple main water valves are electrically connected, and the multiple main water valves are connected in parallel. When multiple main water valves are in the closed state, the main water pump is de-energized, and when at least one of the multiple main water valves is in the open state, the main water pump is energized. The diversion self-replenishing water mechanism and multiple irrigation center mechanisms are powered by a combination of solar energy and mains power.

[0015] Preferably, the first, second, and third wireless transceivers are used for transmitting and receiving range-based signal broadcasts. The range of the signal broadcasts by the first, second, and third wireless transceivers is determined based on the distance between two adjacent main water valves. The range of the signal broadcasts by two adjacent third wireless transceivers is greater than the distance between two adjacent guide channels and less than the distance between two adjacent main water valves.

[0016] A method for using an irrigation unit for large-scale outdoor agricultural planting includes the following steps:

[0017] S1: The installation spacing of multiple water diversion channels and multiple irrigation center mechanisms is determined according to the range and strength of the signal broadcast of the first, second and third wireless transceivers. This ensures that each third wireless transceiver on the water diversion channel can transmit wireless signals with its two adjacent third wireless transceivers without being interfered with by the third wireless transceivers on other water diversion channels. Multiple water diversion channels are arranged linearly along the axis of the main water supply pipe and connected to multiple water injection branch pipes. Multiple irrigation center mechanisms are arranged linearly on the outside of each water diversion channel. By plugging and installing them on the ground and keeping the installation height of multiple ones consistent, each water diversion channel is positioned and supported by multiple water storage tanks, without the need to excavate waterways on the ground to match the water diversion channels.

[0018] S2: Power is turned on, and the water level in the water tank is monitored by the second level gauge. When the water level in the water tank is lower than the set value, the wireless signal between multiple third wireless transceivers is transmitted linearly along the axis of the guide channel to the second wireless transceiver corresponding to the guide channel. At this time, the main water valve is in the open state. Then, after receiving the wireless signal, the multiple second wireless transceivers transmit it linearly along the axis of the main water supply pipe to the first wireless transceiver. The main water pump is electrically connected to multiple main water valves in parallel. When at least one of the multiple main water valves is in the open state, the main water pump is started, so that the main water pump draws water from the water tank and transports it through the main water supply pipe. The opening and closing states of the main water valve and the auxiliary water valve are opposite. Then, the main water supply pipe can deliver water to the main water valve through the auxiliary water valve. Then, the main water valve injects water into the guide channel through the water injection branch pipe.

[0019] S3: An isolation plate is fixed in the middle of the water tank connecting strip, and the height of the isolation plate is lower than the height of the conical filter cover. Thus, multiple isolation plates can be used to precipitate and isolate impurities in the water in the water tank and discharge them centrally through the sewage discharge sleeve. The conical filter cover is isolated from the inner wall of the bottom of the water tank through a guide pipe, and a filter element is provided on the inner side of the conical filter cover, so as to prevent the impurities precipitated in the water tank from entering the inner side of the water storage tank and causing blockage of the auxiliary water pump and nozzle.

[0020] S4: The water in the water delivery tank is guided to the inside of the water storage tank through the conical filter cover and the guide pipe to realize the automatic water replenishment operation of the water storage tank. The fan box is started at regular intervals so that the fan box draws air from the four directions of the irrigation center mechanism through the four air guide pipes and monitors the humidity through the humidity sensor.

[0021] S5: When the humidity around the irrigation center is lower than the set value, the solenoid valve in the corresponding direction will be opened, so that the auxiliary water pump, supported by the water storage tank, draws and pressurizes water through the water delivery hose to the inside of the diversion seat. Then, the water flows through the diversion seat and is sprayed in a directional manner through the solenoid valve and the nozzle, realizing precise irrigation of the agricultural planting area. Multiple irrigation centers can irrigate multiple points in the agricultural planting area. The wireless signal transmission between the diversion self-watering mechanism and multiple irrigation centers can effectively reduce the cost of use and the requirements for cable layout.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. This invention positions and supports each guide channel through multiple water storage tanks. The water level in the water storage tank is monitored by a second level gauge. When the water level in the water storage tank is lower than a set value, the wireless signal between multiple third wireless transceivers is linearly transmitted along the axis of the guide channel to the second wireless transceiver corresponding to the guide channel. The multiple second wireless transceivers are linearly transmitted along the axis of the main water supply pipe to the first wireless transceiver. When at least one of the multiple main water valves is open, the main water pump is started, so that the main water pump draws water from the water storage tank and transports it through the main water supply pipe. The water in the water supply tank is guided to the inside of the water storage tank through the conical filter cover and the guide pipe to achieve automatic water replenishment of the water storage tank.

[0024] 2. This invention uses a timed start-up fan box to draw air from four directions around the irrigation center mechanism through four air ducts and monitors humidity using a humidity sensor. When the humidity around the irrigation center mechanism is lower than a set value, the corresponding solenoid valve is opened, allowing the auxiliary water pump, supported by the water storage tank, to draw and pressurize water through a water delivery hose to the inside of the diversion seat. The water then flows through the diversion seat and is sprayed directionally through the solenoid valve and nozzles, achieving precise irrigation of the agricultural planting area. The irrigation network, composed of the diversion channel and the irrigation center mechanism, can replace the existing pipe and nozzle combination. It can be used for different agricultural planting conditions, and both the diversion channel and the irrigation center mechanism are single devices, making them easy to replace and highly applicable.

[0025] 3. This invention enables multi-point irrigation of agricultural planting areas through multiple irrigation center mechanisms. It achieves wireless signal transmission between the diversion self-replenishing mechanism and multiple irrigation center mechanisms, and transmits signals via a first wireless transceiver, a second wireless transceiver, and a third wireless transceiver. After setting the transmission range and intensity of the signal broadcast, there is no need for signal docking and matching settings, which reduces installation difficulty and labor costs, has low manufacturing costs, and can effectively reduce usage costs and cable routing requirements.

[0039] Please see Figures 1 to 4 An embodiment of the present invention provides an outdoor large-scale agricultural irrigation unit, comprising a diversion and self-replenishing water mechanism 1. The diversion and self-replenishing water mechanism 1 includes a water storage tank 101. A first level gauge 103 is fixedly installed on the surface of the water storage tank 101. A main water pump 104 is fixedly installed on one side of the water storage tank 101. A first wireless transceiver 105 is fixedly installed on the surface of the main water pump 104. A main water supply pipe 102 is fixedly installed at the output end of the main water pump 104. Multiple main water valves 107 and auxiliary water valves 108 are fixedly installed on the outside of the main water supply pipe 102. A water injection branch pipe 106 is fixedly installed on one side of each main water valve 107. A second wireless transceiver 109 is fixedly installed on the upper end of the main water valve 107.

The two ends of the auxiliary water valve 108 are respectively connected to the two ends of the main water valve 107 and are connected to the main water supply pipe 102. The opening and closing states of the main water valve 107 and the auxiliary water valve 108 are opposite. By having the main water valve 107 and the auxiliary water valve 108 work in opposite directions, the main water supply pipe 102 can deliver water to the guide waterway 2 at a fixed point through the main water valve 107.

[0040] Please see Figure 2 , Figure 9 and Figure 10 The diversion and self-watering mechanism 1 has multiple linearly arranged guide channels 2 installed at one end. Each guide channel 2 has multiple linearly arranged irrigation center mechanisms 3 installed on its outer side. The guide channels 2 and irrigation center mechanisms 3 form an irrigation network that can replace the existing pipe and nozzle combination. It can be used for agricultural planting in different situations. The guide channels 2 and irrigation center mechanisms 3 are both single devices, which are easy to replace and have strong applicability.

[0041] The main water supply pipe 102 is perpendicular to the axis of multiple diversion channels 2. The diversion channels 2 include multiple water supply tanks 201. The water injection branch pipe 106 is fixedly connected to one of the water supply tanks 201. A sewage discharge sleeve 203 is fixedly installed on the lower end face of the water supply tank 201. Each pair of adjacent water supply tanks 201 is fixedly connected by a water tank connecting strip 202. An isolation plate 204 is fixedly installed in the middle of the water tank connecting strip 202. Through multiple isolation plates 204, impurities in the water in the water supply tank 201 can be sedimented and isolated, and sewage can be centrally discharged through the sewage discharge sleeve 203.

[0042] Please see Figures 1 to 3 The self-watering mechanism 1 and multiple irrigation center mechanisms 3 provide power to both solar energy and mains electricity, making full use of solar energy resources for large-scale agricultural irrigation, thereby reducing dependence on mains electricity and improving energy efficiency.

[0043] Please see Figures 5 to 8 The irrigation center mechanism 3 includes a water storage tank 301. The upper end face of the water storage tank 301 is provided with a groove. The water delivery channel 201 is inserted into the inner side of the groove. A secondary water pump 303 is fixedly installed on one side of the upper end of the water storage tank 301. The input end of the secondary water pump 303 is inserted into the inner side of the bottom end of the water storage tank 301. A water delivery hose 309 is fixedly installed on the output end of the secondary water pump 303. A second level gauge 302 is fixedly installed on one side of the water storage tank 301. The water level in the water storage tank 301 is monitored by the second level gauge 302 to facilitate the maintenance of a stable water level in the water storage tank 301.

[0044] A guide pipe 305 is fixedly installed in the middle of the upper end of the water storage tank 301. A conical filter cover 306 is fixedly installed at the upper end of the guide pipe 305. The bottom end of the guide pipe 305 passes through the water delivery tank 201 and is connected to the water storage tank 301. A filter element is provided on the inner side of the conical filter cover 306. The conical filter cover 306 is isolated from the inner wall of the bottom end of the water delivery tank 201 by the guide pipe 305. The height of the upper end face of the isolation plate 204 is lower than the height of the upper end face of the conical filter cover 306. The water in the water delivery tank 201 is guided to the inner side of the water storage tank 301 through the conical filter cover 306 and the guide pipe 305 to realize the automatic water replenishment operation of the water storage tank 301. At the same time, it prevents the impurities settled in the water delivery tank 201 from entering the inner side of the water storage tank 301 and causing blockage of the auxiliary water pump 303 and the nozzle 314.

[0045] The four corners of the upper surface of the water storage tank 301 are rotatably connected to connecting sleeves 307. Supporting bent rods 308 are installed on the inner side of the upper end of the connecting sleeves 307. A support plate 310 is installed between the upper ends of the four supporting bent rods 308. The connecting sleeves 307 and the supporting bent rods 308 are connected by threads. The upper ends of the support plate 310 and the four supporting bent rods 308 are rotatably connected by pins. The support plate 310 is fixedly connected to the diverter seat 311. A humidity control module 304 is installed on the upper end of the water supply hose 309. By rotating the connecting sleeves 307, the supporting bent rods 308 can drive the support plate 310 to adjust the installation height of the humidity control module 304.

[0046] Please see Figures 6 to 8The humidity control module 304 includes a diversion base 311. The output end of the auxiliary water pump 303 is connected to the diversion base 311 through a water delivery hose 309. Four solenoid valves 313 are fixedly installed on the outside of the diversion base 311. A spray nozzle 314 is fixedly installed on the end of the solenoid valve 313 away from the diversion base 311. A third wireless transceiver 315 is fixedly installed in the middle of the upper surface of the diversion base 311. A collector base 312 is fixedly installed on the outside of the third wireless transceiver 315. A fan box 318 is fixedly installed on the inner side of the upper end of the 2. Four air guide pipes 316 are fixedly installed on the outer side of the upper end of the collector seat 312. The collector seat 312 is connected to the four air guide pipes 316. The air guide pipes 316 are installed obliquely upward. A humidity sensor 317 is fixedly installed on the inner side of the air guide pipes 316, so that the fan box 318 draws air from the four directions of the irrigation center mechanism 3 through the four air guide pipes 316 and monitors the humidity through the humidity sensor 317.

[0047] The four solenoid valves 313, the nozzles 314, and the air duct 316 are all arranged in a circle relative to the axis of the diverter seat 311. The air duct 316 is located directly above the solenoid valves 313. The second level gauge 302, the auxiliary water pump 303, the third wireless transceiver 315, the four solenoid valves 313, and the four humidity sensors 317 are electrically connected, so that the auxiliary water pump 303 draws and pressurizes water through the water delivery hose 309 to the inside of the diverter seat 311. Then, the water flows through the diverter seat 311 and is sprayed in a direction through the solenoid valves 313 and the nozzles 314 to achieve precise irrigation of the agricultural planting area.

[0048] Please see Figure 4 , Figure 7 and Figure 8 The wireless transmission range of the third wireless transceiver 315 is slightly larger than the distance between the two irrigation center mechanisms 3. Each pair of adjacent third wireless transceivers 315 are connected by wireless transmission. The wireless transmission range of the second wireless transceiver 109 is slightly larger than the distance between the two main water valves 107. Each pair of adjacent auxiliary water valves 108 are connected by wireless transmission. The main water pump 104 is electrically connected to the first wireless transceiver 105. The wireless signals of the multiple third wireless transceivers 315 are transmitted linearly along the axis of the water supply tank 201. The wireless signals of the multiple second wireless transceivers 109 are transmitted linearly along the axis of the main water supply pipe 102. Wireless transmission is carried out between the diversion self-replenishing water mechanism 1 and the multiple irrigation center mechanisms 3, which can effectively reduce the cost of use and the requirements for cable layout.

[0049] The first wireless transceiver 105, the second wireless transceiver 109, and the third wireless transceiver 315 are used for transmitting and receiving range-based signal broadcasts. The range of the signal broadcasts by the first wireless transceiver 105, the second wireless transceiver 109, and the third wireless transceiver 315 is determined based on the distance between two adjacent main water valves 107. The range of the signal broadcasts by two adjacent third wireless transceivers 315 is greater than the distance between two adjacent guide channels 2 and less than the distance between two adjacent main water valves 107. By setting the range and intensity of the signal broadcasts by the first wireless transceiver 105, the second wireless transceiver 109, and the third wireless transceiver 315, it is convenient to determine the spacing between multiple 2s and multiple 3s. At the same time, the signal broadcast transmission is carried out through the first wireless transceiver 105, the second wireless transceiver 109, and the third wireless transceiver 315, without the need for signal docking and matching settings, reducing installation difficulty and manpower expenditure, and resulting in low manufacturing costs.

[0050] Please see Figure 4 The main water pump 104 is electrically connected to multiple main water valves 107, which are connected in parallel. When multiple main water valves 107 are closed, the main water pump 104 is de-energized. When at least one of the multiple main water valves 107 is open, the main water pump 104 is energized, enabling the main water pump 104 to replenish water to the guide channel 2 with low water level through the main water supply pipe 102.

[0051] A method for using an irrigation unit for large-scale outdoor agricultural planting includes the following steps:

[0052] S1: Based on the range and intensity of the signal broadcasts of the first wireless transceiver 105, the second wireless transceiver 109, and the third wireless transceiver 315, the installation spacing of multiple water diversion channels 2 and multiple irrigation center mechanisms 3 is determined to ensure that each third wireless transceiver 315 on the water diversion channel 2 can transmit wireless signals with its two adjacent third wireless transceivers 315 without being interfered with by the third wireless transceivers 315 on other water diversion channels 2. Multiple water diversion channels 2 are arranged linearly along the axis of the main water supply pipe 102 and connected to multiple water injection branch pipes 106. Multiple irrigation center mechanisms 3 are arranged linearly on the outside of each water diversion channel 2. By inserting 301 into the ground and keeping the installation height of multiple 301s consistent, each water diversion channel 2 is positioned and supported by multiple water storage tanks 301, without the need to excavate waterways matching the water diversion channel 2 on the ground.

[0053] S2: Power is turned on, and the water level in the water storage tank 301 is monitored by the second level gauge 302. When the water level in the water storage tank 301 is lower than the set value, the wireless signals between multiple third wireless transceivers 315 are linearly transmitted along the axis of the guide channel 2 to the second wireless transceiver 109 corresponding to the guide channel 2. At this time, the main water valve 107 is in the open state. Then, after receiving the wireless signals, the multiple second wireless transceivers 109 are linearly transmitted along the axis of the main water supply pipe 102 to the first wireless transceiver 105. Among them, the main water pump 104 and multiple The main water valves 107 in parallel are electrically connected. When at least one of the main water valves 107 is open, the main water pump 104 is started, so that the main water pump 104 draws water from the water storage tank 101 and transports it through the water conveying main pipe 102. The opening and closing states of the main water valves 107 and the auxiliary water valves 108 are opposite. Thus, the water conveying main pipe 102 can deliver water to the main water valves 107 at a fixed point through the auxiliary water valves 108. Then, the main water valves 107 inject water into the diversion channel 2 through the water injection branch pipe 106.

[0054] S3: An isolation plate 204 is fixedly installed in the middle of the water tank connecting strip 202, and the height of the isolation plate 204 is lower than the height of the conical filter cover 306. Thus, through multiple isolation plates 204, impurities in the water in the water tank 201 can be settled and isolated, and sewage can be discharged centrally through the sewage discharge sleeve 203. The conical filter cover 306 is isolated from the inner wall of the bottom end of the water tank 201 through the guide pipe 305, and the inner side of the conical filter cover 306 is provided with a filter element, thereby preventing impurities settled in the water tank 201 from entering the inner side of the water storage tank 301 and causing blockage of the auxiliary water pump 303 and the nozzle 314.

[0055] S4: The water in the water delivery tank 201 is guided to the inside of the water storage tank 301 through the conical filter cover 306 and the guide pipe 305 to realize the automatic water replenishment operation of the water storage tank 301. The fan box 318 is started at regular intervals so that the fan box 318 draws air from the four directions of the irrigation center mechanism 3 through the four air guide pipes 316 and monitors the humidity through the humidity sensor 317.

[0056] S5: When the humidity around the irrigation center 3 is lower than the set value, the solenoid valve 313 in the corresponding direction is opened, so that the auxiliary water pump 303, supported by the water storage tank 301, draws and pressurizes water through the water delivery hose 309 to the inside of the diversion seat 311. Then, the water flows through the diversion seat 311 and is sprayed in a direction through the solenoid valve 313 and the nozzle 314, realizing precise irrigation of the agricultural planting area. Multiple irrigation center 3s can irrigate multiple points in the agricultural planting area. The signal wireless transmission between the diversion self-watering mechanism 1 and multiple irrigation center 3s can effectively reduce the cost of use and the requirements for cable layout.

[0057] Example 1:

[0058] The difference between this solution and the one in patent CN202220461004.X, which describes an irrigation device for agricultural planting, is that it adopts a fixed multi-point irrigation center mechanism 3. One end of the diversion and self-watering mechanism 1 is equipped with multiple linearly arranged guide water channels 2. Multiple linearly arranged irrigation center mechanisms 3 are installed on the outside of each guide water channel 2. This allows for the overall irrigation operation of large-scale outdoor agricultural planting areas without the need for movement. At the same time, the multi-point irrigation center mechanism 3 can meet the requirements for precise irrigation of local areas, reducing the cost of equipment use and improving irrigation efficiency. The fan box 318 draws air from the four directions of the irrigation center mechanism 3 through four air pipes 316 and monitors the humidity through a humidity sensor 317. After the water flow is diverted by the diversion seat 311, it is sprayed directionally through the solenoid valve 313 and the nozzle 314. It can also monitor the humidity of the irrigation area and automatically spray, keeping the humidity of the irrigation area stable.

[0059] Example 2:

[0060] The difference between this solution and the irrigation device for greenhouse agricultural planting described in patent CN201810187982.8 is that: the main water valve 107 injects water into the guide channel 2 through the water injection branch pipe 106, and uses the guide channel 2 for water delivery. Water in the water delivery tank 201 is guided to the inside of the water storage tank 301 through the conical filter cover 306 and the guide pipe 305, thus replenishing the water storage tank 301. This allows for timely automatic water replenishment of the irrigation center mechanism 3 at multiple points, reducing the difficulty of water delivery. Furthermore, the wireless signals between multiple third wireless transceivers 315 are linearly transmitted along the axis of the guide channel 2 to the second wireless transceiver 109 corresponding to the guide channel 2. After receiving the wireless signal, transceiver 109 transmits it linearly along the axis of the main water supply pipe 102 to the first wireless transceiver 105. This transmission method avoids the need for cable routing while meeting the requirements of large-scale irrigation operations, saving time and effort. By setting the signal broadcast range of the first wireless transceiver 105, the second wireless transceiver 109, and the third wireless transceiver 315, it is easy to determine the spacing between multiple 2s and multiple 3s. At the same time, the signal broadcast transmission is carried out through the first wireless transceiver 105, the second wireless transceiver 109, and the third wireless transceiver 315, eliminating the need for signal docking and matching settings, reducing installation difficulty and labor costs, and lowering manufacturing costs.

9. A method of using the outdoor large-scale agricultural irrigation unit according to claim 8, characterized in that, Includes the following steps: S1: The installation spacing of multiple water diversion channels (2) and multiple irrigation center mechanisms (3) is determined based on the range and strength of the signal broadcasts of the first wireless transceiver (105), the second wireless transceiver (109), and the third wireless transceiver (315), to ensure that each third wireless transceiver (315) on the water diversion channel (2) can transmit wireless signals with its two adjacent third wireless transceivers (315) without being affected by the third wireless transceivers (315) on other water diversion channels (2). To prevent interference, multiple diversion channels (2) are arranged linearly along the axis of the main water supply pipe (102) and connected to multiple water injection branch pipes (106). Multiple irrigation center mechanisms (3) are arranged linearly on the outside of each diversion channel (2). By inserting and installing the water storage tank (301) on the ground and keeping the installation height of multiple water storage tanks (301) consistent, each diversion channel (2) is positioned and supported by multiple water storage tanks (301), without the need to excavate waterways matching the diversion channels (2) on the ground. S2: Power is turned on, and the water level in the water storage tank (301) is monitored by the second level gauge (302). When the water level in the water storage tank (301) is lower than the set value, the wireless signal between multiple third wireless transceivers (315) is transmitted linearly along the axis of the guide channel (2) to the second wireless transceiver (109) corresponding to the guide channel (2). At this time, the main water valve (107) is in the open state. Then, after receiving the wireless signal, multiple second wireless transceivers (109) transmit the signal linearly along the axis of the main water supply pipe (102) to the first wireless transceiver (105). The main water pump (104) and multiple transceivers in parallel... The main water valve (107) in the connected state is electrically connected. When at least one of the main water valves (107) is in the open state, the main water pump (104) is started, so that the main water pump (104) draws water from the reservoir (101) and transports it through the water conveying main pipe (102). The opening and closing states of the main water valve (107) and the auxiliary water valve (108) are opposite. Thus, the water conveying main pipe (102) can deliver water to the main water valve (107) at a fixed point through the auxiliary water valve (108). Then the main water valve (107) injects water into the guide channel (2) through the water injection branch pipe (106). S3: A partition plate (204) is fixedly installed in the middle of the water tank connecting strip (202), and the height of the partition plate (204) is lower than the height of the cone filter cover (306). Thus, through multiple partition plates (204), impurities in the water in the water tank (201) can be sedimented and isolated, and sewage can be discharged centrally through the sewage discharge sleeve (203). The cone filter cover (306) is isolated from the inner wall of the bottom end of the water tank (201) through the guide pipe (305), and the inner side of the cone filter cover (306) is provided with a filter element, thereby preventing the impurities sedimented in the water tank (201) from entering the inner side of the water storage tank (301) and causing blockage of the auxiliary water pump (303) and the nozzle (314). S4: The water in the water delivery tank (201) is guided to the inside of the water storage tank (301) through the conical filter cover (306) and the guide pipe (305) to realize the automatic water replenishment operation of the water storage tank (301). The fan box (318) is started at regular intervals so that the fan box (318) draws air from the four directions of the irrigation center mechanism (3) through the four air guide pipes (316) and monitors the humidity through the humidity sensor (317). S5: When the humidity around the irrigation center (3) is lower than the set value, the solenoid valve (313) in the corresponding direction is opened, so that the auxiliary water pump (303) is supported by the water storage tank (301) and pumps water through the water delivery hose (309) to the inside of the diversion seat (311). Then, the water flows through the diversion seat (311) and is sprayed in a direction through the solenoid valve (313) and the nozzle (314) to achieve precise irrigation of the agricultural planting area. Multiple irrigation center mechanisms (3) can irrigate multiple points in the agricultural planting area. The signal wireless transmission between the diversion self-water replenishment mechanism (1) and multiple irrigation center mechanisms (3) can effectively reduce the cost of use and the requirements for cable layout.
