[0002] Planting is a major component of agriculture. It utilizes the life functions of plants to produce food, supplementary foods, feed, and industrial raw materials through artificial cultivation. This includes the cultivation of various crops, trees, fruit trees, medicinal plants, and ornamental plants. During agricultural cultivation, crops require irrigation to save labor and improve efficiency.

[0003] Patent number CN202220461004.X is an agricultural planting irrigation device. Although it is convenient to provide a new type of mobile irrigation equipment, the support device replicates the open ends of the mobile irrigation equipment through the work of the support device, avoiding the mobile irrigation equipment from tilting due to the movement of the mobile irrigation equipment or uneven force on the two ends, which affects the agricultural irrigation work. The support device moves with the movement of the mobile irrigation equipment, while meeting the function of supporting the mobile irrigation equipment without affecting the work of the mobile irrigation equipment. Patent number CN201810187982.8 is an indoor agricultural planting irrigation device. Although it has a simple structure, it can greatly increase the irrigation range, is easy to install, does not require manual operation, has high efficiency, requires less labor, and is more practical. However, it cannot meet the needs of overall irrigation of existing large-scale outdoor agricultural planting areas, and it cannot provide targeted and directional irrigation for local areas.

The main water pump is electrically connected to the first wireless transceiver, and the wireless signals of multiple third wireless transceivers are transmitted linearly along the axis of the water trough, and the wireless signals of multiple second wireless transceivers are transmitted linearly along the axis of the water main.

[0012] Preferably, the main water pump is electrically connected to multiple main water valves, and the multiple main water valves are in parallel. When the multiple main water valves are in a closed state, the main water pump is powered off. When at least one of the multiple main water valves is in an open state, the main water pump is powered on.

The range of the signal broadcasts of two adjacent third wireless transceivers is greater than the distance between two adjacent diversion channels and less than the distance between two adjacent main water valves.

[0014] A method for using an outdoor large-scale agricultural planting irrigation unit comprises the following steps: S1: Determine the installation spacing of multiple diversion waterways and multiple irrigation center mechanisms based on the signal broadcast range and strength of the first wireless transceiver, the second wireless transceiver, and the third wireless transceiver, ensuring that each third wireless transceiver on a diversion waterway can transmit wireless signals to two adjacent third wireless transceivers without interference from third wireless transceivers on other diversion waterways. Arrange the multiple diversion waterways linearly along the axis of the water main and connect them to multiple water injection branch pipes. Multiple irrigation center mechanisms are linearly arranged on the outside of each diversion waterway. By installing the diversion waterways on the ground and maintaining the same installation height, each diversion waterway is positioned and supported by multiple water storage tanks, eliminating the need to excavate a waterway on the ground to match the diversion waterway. S2: Turn on the power supply and monitor the water level in the water tank through the second liquid level gauge. When the water level in the water tank is lower than the set value, the wireless signals between the multiple third wireless transceivers are linearly transmitted along the axis of the diversion waterway to the second wireless transceiver corresponding to the diversion waterway. At this time, the main water valve is in the open state. Then, after receiving the wireless signals, the multiple second wireless transceivers linearly transmit them to the first wireless transceiver along the axis of the water main. The main water pump is electrically connected to the multiple main water valves in parallel. Then, 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 reservoir and transports it through the water main. The opening and closing states of the main water valve and the auxiliary water valve are opposite. Then, the water main can transport water to the main water valve at a fixed point through the auxiliary water valve. Then, the main water valve performs water injection operation into the diversion waterway through the water injection branch pipe. S3: An isolation plate is fixedly installed in the middle of the water tank connecting strip, and the height of the isolation plate is lower than that of the conical filter cover. The multiple isolation plates can precipitate and isolate impurities in the water of the water tank and discharge them centrally through the sewage sleeve. The conical filter cover is separated from the inner wall of the bottom of the water tank by a guide pipe, and a filter element is installed on the inside of the conical filter cover to prevent impurities precipitated in the water tank from entering the inner side of the water storage tank and clogging the auxiliary water pump and nozzle. S4: The water in the water trough is diverted to the inner side 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 a fixed time, so that the fan box draws air from four directions of the irrigation center through four air guide pipes and monitors the humidity through the humidity sensor; S5: When the humidity around the irrigation center mechanism 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 tank, will pump water through the water hose and pressurize it to the inside of the diverter seat. Then, the water will be diverted through the diverter seat and then sprayed in a direction through the solenoid valve and the nozzle, so as to realize the precise irrigation operation of the agricultural planting area. The agricultural planting area can be irrigated at multiple points through multiple irrigation center mechanisms. The signal is wirelessly transmitted between the diversion self-replenishing mechanism and the multiple irrigation center mechanisms, which can effectively reduce the use cost and cable layout requirements.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention positions and supports each diversion channel through multiple water tanks, monitors the water level in the water tank using a second liquid level gauge, and when the water level in the water tank falls below a set value, wireless signals between multiple third wireless transceivers are linearly transmitted along the axis of the diversion channel to the second wireless transceiver corresponding to the diversion channel. The multiple second wireless transceivers are then linearly transmitted along the axis of the water main to the first wireless transceiver. When at least one of the multiple main water valves is open, the main water pump is activated, causing the main water pump to pump water from the reservoir and transport it through the water main. The water in the water trough is then diverted to the inside of the water tank via the conical filter cover and the diversion pipe, thereby automatically replenishing the water tank. 2. The present invention starts the fan box at a fixed time, so that the fan box extracts air from the four directions of the irrigation center mechanism through four air guide pipes and monitors the humidity through a humidity sensor. When the humidity around the irrigation center mechanism is lower than the set value, the solenoid valve in the corresponding direction is opened, so that the auxiliary water pump, supported by the water storage tank, extracts and pressurizes water to the inner side of the diverter seat through the water hose. Then, the water flows through the diverter seat and is sprayed directionally through the solenoid valve and the nozzle, thereby achieving precise irrigation of the agricultural planting area. The irrigation network composed of the diversion waterway and the irrigation center mechanism can replace the existing pipe and nozzle combination, and can be used for agricultural planting in different situations. The diversion waterway and the irrigation center mechanism are both single devices, which are easy to replace and have strong applicability. 3. The present invention can carry out multi-point irrigation in agricultural planting areas through multiple irrigation center mechanisms, wirelessly transmit signals between the diversion self-replenishing mechanism and multiple irrigation center mechanisms, and broadcast signal transmission through the first wireless transceiver, the second wireless transceiver and the third wireless transceiver. After setting the transmission range and transmission strength of the signal broadcast, there is no need to connect and match the signal, which reduces the installation difficulty and manpower expenditure, has low manufacturing cost, and can effectively reduce the use cost and cable arrangement requirements.

The conical filter cover 306 and the guide pipe 305 are used to guide the water in the water trough 201 to the inner side of the water storage tank 301 to realize automatic water replenishment operation of the water storage tank 301, while preventing impurities precipitated in the water trough 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.

[0024] See also Figures 6 to 8The humidity control module 304 includes a diverter seat 311.

[0026] See also Figure 4 The main water pump 104 is electrically connected to the multiple main water valves 107, and the multiple main water valves 107 are in parallel. When the multiple main water valves 107 are in the closed state, the main water pump 104 is powered off. When at least one of the multiple main water valves 107 is in the open state, the main water pump 104 is powered on, so that the main water pump 104 can replenish water to the diversion waterway 2 with too low water level in time through the water main 102.

[0027] A method for using an outdoor large-scale agricultural planting irrigation unit comprises the following steps: S1: Determine the installation spacing of the multiple diversion waterways 2 and the multiple irrigation center mechanisms 3 based on the signal broadcast range and strength of the first wireless transceiver 105, the second wireless transceiver 109, and the third wireless transceiver 315, ensuring that each third wireless transceiver 315 on the diversion waterway 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 diversion waterways 2. Arrange the multiple diversion waterways 2 linearly along the axis of the water transmission main 102 and connect them to the multiple water injection branch pipes 106. Multiple irrigation center mechanisms 3 are linearly arranged on the outside of each diversion waterway 2. By plugging 301 and installing them on the ground and maintaining the installation height of the multiple 301s at the same level, each diversion waterway 2 is positioned and supported by the multiple water storage tanks 301, eliminating the need to excavate a waterway on the ground that matches the diversion waterway 2. S2: Turn on the power supply and monitor the water level in the water tank 301 through the second liquid level gauge 302. When the water level in the water tank 301 is lower than the set value, the wireless signals between the multiple third wireless transceivers 315 are linearly transmitted along the axis of the diversion channel 2 to the second wireless transceiver 109 corresponding to the diversion 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 linearly transmit them to the first wireless transceiver 105 along the axis of the water main 102. The main water pump 104 and the multiple wireless transceivers 315 are connected. The main water valves 107 in parallel are electrically connected. When at least one of the multiple main water valves 107 is in the open state, the main water pump 104 is activated, so that the main water pump 104 draws water from the water reservoir 101 and delivers it through the water main 102. The main water valve 107 and the auxiliary water valve 108 have opposite opening and closing states. The water main 102 can deliver water to the main water valve 107 at a fixed point through the auxiliary water valve 108. The main water valve 107 then injects water into the diversion channel 2 through the water injection branch pipe 106. S3: An isolation plate 204 is fixedly provided in the middle of the water tank connecting strip 202, and the height of the isolation plate 204 is lower than that of the conical filter cover 306. Thus, the multiple isolation plates 204 can precipitate and isolate impurities in the water of the water tank 201 and centrally discharge the impurities through the sewage sleeve 203. The conical filter cover 306 is separated from the inner wall of the bottom end of the water tank 201 by a guide pipe 305, and a filter element is provided on the inner side of the conical filter cover 306, thereby preventing impurities precipitated in the water tank 201 from entering the inner side of the water storage tank 301 and clogging the auxiliary water pump 303 and the nozzle 314. S4: The water in the water trough 201 is directed to the inner side of the water storage tank 301 through the conical filter cover 306 and the guide pipe 305 to automatically replenish the water storage tank 301. The fan box 318 is started at a fixed time, so that the fan box 318 draws air from 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 ambient humidity of the irrigation center mechanism 3 is lower than the set value, the solenoid valve 313 in the corresponding direction is opened, so that the auxiliary water pump 303, under the support of the water tank 301, draws water and pressurizes it to the inner side of the diverter seat 311 through the water hose 309. Then, the water flows through the diverter seat 311 and is then directionally sprayed through the solenoid valve 313 and the nozzle 314, thereby realizing precise irrigation operation of the agricultural planting area. Through multiple irrigation center mechanisms 3, multi-point irrigation of the agricultural planting area can be carried out. By wirelessly transmitting signals between the diversion self-water replenishment mechanism 1 and multiple irrigation center mechanisms 3, the use cost and cable layout requirements can be effectively reduced.

[0028] Example 1: The difference between this solution and the agricultural planting irrigation device with patent number CN202220461004.X is that: it adopts a fixed multi-point irrigation center mechanism 3, in which a plurality of linearly arranged diversion water channels 2 are installed at one end of the diversion self-water replenishment mechanism 1, and a plurality of linearly arranged irrigation center mechanisms 3 are installed on the outside of each diversion water channel 2, so that the overall irrigation operation of outdoor large-scale agricultural planting areas can be met without moving. At the same time, the multi-point irrigation center mechanism 3 can meet the requirements of precise irrigation of local areas, reduce the use cost of equipment, and improve irrigation efficiency. The fan box 318 extracts air from the four directions of the irrigation center mechanism 3 through four air guide pipes 316 and monitors the humidity through the humidity sensor 317. After the water is diverted by the diversion seat 311, it is directionally sprayed through the solenoid valve 313 and the nozzle 314, and can monitor the humidity of the irrigation area and automatically sprinkle irrigation to keep the humidity of the irrigation area stable.

[0029] Example 2: The difference between this solution and the irrigation device for agricultural planting in a greenhouse with patent number CN201810187982.8 is that the main water valve 107 injects water into the diversion waterway 2 through the water injection branch pipe 106, and uses the diversion waterway 2 to carry out water delivery operations. The water in the water delivery trough 201 is diverted to the inner side of the water storage tank 301 through the conical filter cover 306 and the diversion pipe 305 to replenish the water storage tank 301. It can automatically replenish water to the irrigation center mechanism 3 at multiple points in time, reducing the difficulty of water delivery, and the wireless signals between the multiple third wireless transceivers 315 are linearly transmitted along the axis of the diversion waterway 2 to the second wireless transceiver 109 corresponding to the diversion waterway 2. After receiving the wireless signal, the transceiver 109 transmits it linearly along the axis of the water main 102 to the first wireless transceiver 105. The transmission-type wireless signal transmission can meet the needs of large-scale irrigation operations while avoiding the need to arrange cables, 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 convenient to build and determine the spacing between multiple 2s and multiple 3s. At the same time, the signal broadcast is transmitted by 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 low manufacturing cost.
