When the leakage hole 710 corresponds to the water outlet pipe 703, the power-on component 802 is separated from the conductor 805.

[0024] Specifically, as more and more rainwater is transported to the rectangular material holding chamber 709, the reset spring 711 will contract, thereby driving the rectangular material holding chamber 709, the first slider 705, the circular connecting block 801 and the conductor 805 to move downward until the leakage hole 710 corresponds to the outlet pipe 703. At this time, the circular conductive block 807 is separated from the conductor 805, thereby powering off the feed pump 6. This will cause the power-off component 8, the rainwater monitoring component 7 and the feed pump 6 to produce a linkage effect, so that the irrigation device stops the irrigation operation on rainy days, thereby improving the utilization rate of the nutrient solution, improving the effect of the plant's absorption of nutrients, and at the same time improving the irrigation efficiency of the irrigation device.

[0025] See also Figure 1 and Figure 2A rectangular frame 9 is connected to the outside of the power-off component 8, a second rectangular slide groove 10 is opened at one end of the rectangular frame 9 facing the first slider 705, and a second power transmission line 11 is connected to one end of the power-off component 8 facing the pouring chamber 1, an insulating frame 12 is connected to the outside of the second power transmission line 11, and the end of the second power transmission line 11 away from the power-off component 8 is connected to the feed pump 6.

[0026] See also Figure 5 and Figure 6 The lower surface of the monitoring cavity 701 at one end away from the pouring cavity 1 is connected with several water outlet pipes 703, the top of the monitoring cavity 701 is connected with a filter screen 706, the lower part of the filter screen 706 is connected with a rectangular reset plate 707, a conveying cavity 708 is provided below the rectangular reset plate 707, a rectangular material holding cavity 709 is connected to the inner cavity of the conveying cavity 708, several water leakage holes 710 are provided on the lower surface of the end of the rectangular material holding cavity 709 away from the pouring cavity 1, and several reset springs 711 are connected to the lower end surface of the rectangular material holding cavity 709, and the rectangular reset plate 707 is rotatably connected to the monitoring cavity 701, and second reset springs are connected to both sides of one end of the rectangular reset plate 707, and the principle of the rectangular reset plate 707 refers to the tape measure.

[0027] See also Figure 5 and Figure 6 The surface of one end of the rectangular material holding chamber 709 facing the power-off component 8 is connected to the first slider 705, the number of the outlet pipes 703 is the same as the number of the leakage holes 710 opened on the surface of the rectangular material holding chamber 709, and the leakage holes 710 correspond to the outlet pipes 703, and the rainwater is transported to the rectangular material holding chamber 709 through the conveying chamber 708. As the amount of rainwater in the rectangular material holding chamber 709 increases, the reset spring 711 will contract, so that the rectangular material holding chamber 709 will slowly descend, thereby driving the first slider 705 to move downward along the first rectangular slide groove 704 until the leakage holes 710 correspond to the outlet pipes 703. At this time, the rainwater in the rectangular material holding chamber 709 will be transported to the outside through the outlet pipe 703.

[0028] See also Figure 7The power-on component 802 includes a circular fixing block 806, one end of the circular fixing block 806 facing the circular connecting block 801 is connected to a circular conductive block 807, one end of the circular conductive block 807 away from the circular connecting block 801 is connected to a conductive wire 808, one end of the conductive wire 808 away from the circular conductive block 807 is connected to a first conductive block 809, one end of the first conductive block 809 away from the conductive wire 808 is connected to a wire connecting block 810, a connecting hole 811 is provided on the surface of the wire connecting block 810, and one end of the wire connecting block 810 is connected to a threaded fixing rod 812, and the threaded fixing rod 812 serves to fix the transmission line, and the feed pump 6, the second transmission line 11, the power-on component 802, the conductor 805 and the first transmission line 803 form a loop.

[0029] See also Figure 8 The blocking component 4 includes a circular blocking block 401, the lower end of the circular blocking block 401 is connected to a circular connecting rod 402, the lower end of the circular connecting rod 402 is connected to a rectangular floating block 403, the lower end of the rectangular floating block 403 is connected to a circular triggering block 404, and the outer side of the circular connecting rod 402 is connected to a circular frame 405, both ends of the circular frame 405 are provided with a third rectangular chute 406, and the bottom end of the inner cavity of the circular frame 405 is provided with a triggering groove 407. When the triggering groove 407 is matched with the circular triggering block 404, the feed pump 6 will be driven, and the rectangular floating block 403 passes through the third rectangular chute 406 and is located outside, and the circular blocking block 401 is matched with the feed port 3.

[0030] Specifically, the nutrient solution is delivered to the plants through the irrigation nozzle. As the nutrient solution is continuously output, the nutrient solution stored in the irrigation chamber 1 will continue to decrease, thereby moving the rectangular floating block 403, the circular blocking block 401, the circular connecting rod 402 and the circular trigger block 404 downward along the third rectangular slide groove 406. When the circular trigger block 404 coincides with the trigger groove 407, the central control system will start the second delivery pump and let the delivery pipe deliver the nutrient solution to the irrigation chamber 1. In this way, the storage amount of the nutrient solution in the irrigation chamber 1 is monitored through the blocking component 4. When the storage amount of the nutrient solution in the irrigation chamber 1 is reduced to a certain extent, the nutrient solution will be delivered to the irrigation chamber 1, thereby improving the irrigation efficiency of the irrigation device.

[0031] The connecting hole 811 connected to one end of the pouring chamber 1 is connected to the second power transmission line 11 , and the surface of one end of the circular connecting block 801 close to the rain monitoring component 7 is connected to the first sliding block 705 .

[0032] Working principle: First, the nutrient solution is delivered to the feed port 3 through the delivery pipe, and then delivered to the irrigation chamber 1 through the feed port 3. As more and more nutrient solution is delivered to the irrigation chamber 1, the rectangular floating block 403 is driven to move upward along the third rectangular chute 406, thereby driving the circular connecting rod 402 and the circular blocking block 401 to move upward until the circular blocking block 401 fits with the feed port 3. At this time, the feed port 3 is blocked and the delivery of the nutrient solution is stopped; When the irrigation chamber 1 is filled with nutrient solution, the Internet of Things will monitor the growth needs of the plants. If the plants need to be irrigated with nutrient solution, the delivery pump 6 will be started, and the nutrient solution in the irrigation chamber 1 will be delivered to the irrigation nozzle through the discharge pipe 5, and then the nutrient solution will be delivered to the plants through the irrigation nozzle. As the nutrient solution is continuously discharged, the nutrient solution stored in the irrigation chamber 1 will be continuously reduced, so that the rectangular floating block 403, the circular blocking block 401, the circular connecting rod 402 and the circular trigger block 404 will move downward along the third rectangular slide groove 406. When the circular trigger block 404 coincides with the trigger groove 407, the second delivery pump will be started and the delivery pipe will deliver the nutrient solution to the irrigation chamber 1. In addition, during the long-term irrigation process, the irrigation device may encounter rainy weather, and the rainwater will be transported along the canopy 2 to the inner cavity of the monitoring cavity 701, thereby generating a pressure on the rectangular reset plate 707, thereby causing the rectangular reset plate 707 to rotate and allow the rainwater to be transported to the transport cavity 708, and then to the rectangular material holding cavity 709. As more and more rainwater is in the rectangular material holding cavity 709, the reset spring 711 will be contracted, thereby driving the rectangular material holding cavity 709 and the first slider 705 to move downward until the leak hole 710 corresponds to the water outlet pipe 703. At this time, the rainwater in the rectangular material holding cavity 709 will be transported to the outside through the water outlet pipe 703. The first slider 705 moves downward along the first rectangular slot 704, which drives the circular connecting block 801 downward. As the circular connecting block 801 moves downward, the conductor 805 moves downward. When the water leakage hole 710 corresponds to the water outlet pipe 703, the conductor 805 is separated from the circular conductive block 807, so that the circuit formed by the feed pump 6, the first transmission line 803, the power supply component 802 and the conductor 805 is powered off, and the irrigation device stops the irrigation operation. When the rain stops, Without the continuous input of rainwater, the amount of rainwater in the rectangular material holding chamber 709 will become less and less, allowing the reset spring 711 to return to its original position, and separating the water leakage hole 710 and the water outlet pipe 703. Then, the circular connecting block 801 and the conductor 805 will move upward, allowing the conductor 805 and the circular conductive block 807 to return to their original positions, and allowing the feed pump 6, the first transmission line 803, the power-on component 802 and the conductor 805 to form a loop, and allowing the irrigation device to continue the irrigation operation, thus ending all operations.
