DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0020] Please refer to Figures 1-3 , an embodiment provided by the present invention: a planting irrigation device, including an electric water pump 1, a PLC controller 2, a connecting water pipe 3, a sprinkler connection part 4, a support fixing plate 5 and a check valve 14. A support arc plate 11 is fixedly connected to the top end of the support fixing plate 5, and inserting rods 12 are evenly and fixedly connected to the bottom end of the support fixing plate 5. A soil humidity sensor 13 is snap-connected to one of the inserting rods 12. Two connecting part fixing plates 6 are symmetrically and fixedly installed at the top end of the support arc plate 11.
[0021] The middle part of the top end of the sprinkler connection part 4 is fixedly connected with a sprinkler support water pipe 7. The top end of the sprinkler support water pipe 7 is threadedly connected with a branch head 8. Sprayers 9 are evenly fixedly installed on the outer side of the branch head 8. An electromagnetic valve 10 is fixedly installed at the bottom end of the sprinkler support water pipe 7. The sprinkler connection part 4 is fixedly installed at the middle part of the top end of the support fixing plate 5 through the connecting part fixing plate 6.
[0022] One end of the connecting water pipe 3 is fixedly installed at the output end of the electric water pump 1, and the other end of the connecting water pipe 3 is fixedly installed at one end of the sprinkler connection part 4. The PLC controller 2 is arranged on the electric water pump 1. The check valve 14 is fixedly installed at the output end of the electric water pump 1, and the check valve 14 opens in the direction away from the electric water pump 1. The electric water pump 1 can transport water through the one-way opening of the check valve 14. When the electric water pump 1 is closed, the check valve 14 closes to prevent the water in the water circuit from flowing back and improve the water output rate of the next irrigation.
[0023] The PLC controller 2 is respectively connected to the electric water pump 1, the electromagnetic valve 10 and the soil humidity sensor 13 in a wired electrical connection. By setting a control program in the PLC controller 2 and setting a corresponding humidity threshold according to plants or crops, the electromagnetic valve 10 and the soil humidity sensor 13 located on the same support fixing plate 5 are in the same group, so that irrigation operations can be carried out according to the humidity data transmitted by the soil humidity sensor 13 at the corresponding position.
[0024] The middle part of the top end of the supporting arc plate 11 is designed in an arc shape. The middle part of the bottom end of the connecting part fixing plate 6 is designed in an arc shape. A notch matching the irrigation support water pipe 7 is opened on one side of the connecting part fixing plate 6 close to the irrigation support water pipe 7. The outer side of the bottom end of the connecting part fixing plate 6 is fixedly installed on the outer side of the top end of the supporting arc plate 11 through bolts. The irrigation connecting part 4 is fixed on the supporting arc plate 11 through the connecting part fixing plate 6, and the irrigation support water pipe 7 is clamped in the middle through the notch on the connecting part fixing plate 6 so that the irrigation support water pipe 7 remains in a vertical state.
[0025] The irrigation connecting part 4 and the irrigation support water pipe 7 are made of hard plastic material, which has a low cost and is corrosion-resistant. The support fixing plate 5 and the insertion rod 12 are made of alloy stainless steel material, and the alloy stainless steel has high strength and is convenient for fixing the irrigation connecting part 4.
[0026] Working principle: During use, first set the control program through the PLC controller 2 and set the corresponding humidity threshold according to the plants or crops. The solenoid valve 10 and the soil humidity sensor 13 located on the same support fixed plate 5 are in the same group. Then, take out the corresponding number of support fixed plates 5 according to the planting range of the plants or crops and the coverage range of the nozzles 9 on the support fixed plate 5. Then, evenly place the support fixed plate 5 on the land where the plants or crops are planted by external force. Then, press the support fixed plate 5 downward by external force. The movement of the support fixed plate 5 squeezes the insertion rod 12 to move downward and insert into the land. At the same time, insert the soil humidity sensor 13 into the soil by external force, or remove the soil humidity sensor 13 from the insertion rod 12 and insert it into the nearby soil. Then, place the sprinkler connection part 4 on the inner side of the top end of the support arc plate 11 and fix the sprinkler connection part 4 on the inner side of the support arc plate 11 through the connection part fixing plate 6. Then, connect all the sprinkler connection parts 4 through the connecting water pipe 3, and connect the sprinkler connection part 4 closest to the electric water pump 1 to the output end of the electric water pump 1 through the connecting water pipe 3, and connect the input end of the electric water pump 1 to the water source. Plug the other end of the sprinkler connection part 4 at the end. After the installation is completed, the soil humidity sensor 13 transmits the soil humidity data to the PLC controller 2 in real time. The PLC controller 2 makes a judgment according to the preset humidity threshold. When the PLC controller 2 receives that the humidity data transmitted by the soil humidity sensor 13 is lower than the threshold, the PLC controller 2 controls the solenoid valve 10 in the same group as the soil humidity sensor 13 to open. Then, according to the number of soil humidity sensors 13 with humidity lower than the threshold, control the electric water pump 1 to start the corresponding power. The electric water pump 1 conveys water to the output end. Under the impact of the water flow, the one-way valve 14 opens and conveys the water to the connecting water pipe 3. The water is conveyed to the entire water circuit through the connecting water pipe 3. When the water passes through the sprinkler connection part 4 where the solenoid valve 10 is opened, the water flows into the sprinkler support water pipe 7 and is sprayed through the nozzle 9 for irrigation. When the irrigation time ends, the PLC controller 2 controls the electric water pump 1 to close, and then controls the opened solenoid valve 10 to close. After the electric water pump 1 closes, the one-way valve 14 closes to prevent the water in the water circuit from flowing back.
[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
