Compared with the traditional irrigation scheme, it can be automatically adjusted, and water-saving irrigation mainly includes drip irrigation, sprinkler irrigation, micro-sprinkler irrigation, and seepage irrigation.

[0003] Although the current sprinkler device is widely used in agricultural water conservancy projects, it still has many defects in use, specifically as follows: when the sprinkler equipment is used for a period of time, the nozzle is blocked due to salinization or hard water. Because the nozzle is blocked, the pipe pressure increases, which in turn causes the water pump pressure to increase, ultimately causing the power of the water pump to increase, increasing the power consumption. The clogging of the nozzle also causes uneven sprinkling, which affects crop growth. In addition, it may also cause the pipe to burst. In the sprinkler pipeline, an accumulator is generally provided to relieve the water pressure during irrigation. However, the current sprinkler device does not have secondary protection measures. When the water pressure exceeds the range of the accumulator pressure, the nozzle will still have a probability of damage.

[0022] When the pressure value monitored by the water pressure sensor 40 is greater than the set threshold value, and the pressure value remains unchanged for a long time or slowly rises for a long time, it indicates that the nozzle 6 is blocked, at this time, the electromagnetic force is used to drive the buffer assembly 7 to operate, one is to reduce the water pressure near the nozzle 6, prevent the phenomenon of pipe 2 burst, in addition, due to the meshing connection between the buffer assembly 7 and the blocking assembly 8, the buffer assembly 7 operates and synchronously drives the blocking assembly 8 to block the communication between the mounting assembly 9 and the connecting pipe 4, so that water no longer flows into the nozzle 6, the blocking assembly 8 operates and synchronously drives the mounting assembly 9 to rotate, under the limiting action of the limiting column 10, the nozzle 6 does not rotate when the mounting assembly 9 rotates, thereby making the nozzle 6 fall off from the threads of the mounting assembly 9 and fall to the ground, at this time, the turnover assembly 20 is started to turn over, driving the standby nozzle 6 on the turnover assembly 20 to turn over to the position aligned with the mounting assembly 9, then the electromagnetic force is used to drive the buffer assembly 7 and the blocking assembly 8 to move reversely, thereby driving the mounting assembly 9 to rotate reversely, and then the standby nozzle 6 is screwed on the mounting assembly 9 through the thread action, realizing the replacement of the nozzle 6, thereby solving the problem of nozzle blockage, without manual replacement, the degree of automation is high, in addition, after replacing the new nozzle 6, the water pressure in the pipe 2 is reduced, reducing the probability of pipe 2 burst, and making the load of the water pump return to normal level, which is beneficial to reduce the power of the water pump, playing a role in energy saving and environmental protection; As shown in Figure 4 , Figures 7-8 and Figures 11-12 , the buffer assembly 7 comprises a hollow slide column 71 slidably installed in the cylinder 5, the hollow slide column 71 and the cylinder 5 are elastically connected through the spring one 72, a plurality of water holes 73 are formed in the bottom surface of the hollow slide column 71, a rack one 74 is fixedly installed on one side outer wall of the hollow slide column 71, a cut-off assembly 75 is rotatably installed on the other side outer wall of the hollow slide column 71, a pair of permanent magnets one 76 are also fixedly installed on the other side outer wall of the hollow slide column 71, a pair of electromagnets one 77 are fixedly installed in the side wall of the inner cavity of the cylinder 5, and the permanent magnets one 76 and the electromagnets one 77 are aligned.

[0023] As shown in Figure 3 , the connecting pipe 4 comprises a pipe body 41 fixedly and communicatively installed on the bottom surface of the mounting seat 3, as shown in Figure 4 , a water outlet hole 42 is formed in the bottom surface of the pipe body 41, when the electronic water valve 50 is opened, the water in the pipe 2 will enter the nozzle 6 through the mounting seat 3, the pipe body 41 and the water outlet hole 42, and then be sprayed from the nozzle 6 for sprinkling irrigation, the bottom of the pipe body 41 is also provided with a cavity 43, and the cavity 43 and the water outlet hole 42 are communicatively arranged, as shown in Figure 14 , an installation groove 44 is formed in the side wall of the pipe body 41.

[0024] As shown in Figure 4 andFigure 7 As shown, the cylinder 5 includes a cylinder body 51 fixedly installed on the outer wall of the pipe body 41 on both sides of the lower part, and a pair of sliding grooves 53 are formed in the inside of the cylinder body 51. The hollow slide column 71 is slidingly installed on the sliding grooves 53, and the sliding grooves 53 limit the hollow slide column 71, so that the hollow slide column 71 can slide according to the preset track. The water outlet 52 is formed on the circumferential side wall of the cylinder body 51. When the buffer assembly 7 is under the buffer pressure, a part of the water will be discharged, and the discharged water will enter the water collecting assembly 30 through the water outlet 52 for collection and recycling.

[0025] As shown in Figure 2 and Figure 5 The water collecting assembly 30 includes an L-shaped support 301 fixedly installed on the circumferential side wall of the pipeline 2, and the horizontal end of the L-shaped support 301 is fixedly connected with a water collecting box 302. The water collecting box 302 is arranged directly below the water outlet 52, and the bottom of the water collecting box 302 is communicated with a water pipe 303. The water pipe 303 is connected with a water storage tank (not shown in the figure). The water discharged from the water outlet 52 will flow into the water collecting box 302, and the water in the water collecting box 302 will flow into the water storage tank (not shown in the figure) connected outside through the water pipe 303, for unified collection and recycling.

[0026] As shown in Figure 7 Figure 10 The hollow slide column 71 includes a slide column body 711 slidingly installed in the sliding groove 53, and a pair of accommodation grooves 712 are formed in the side wall of the slide column body 711.

[0027] As shown in Figures 9-10 The intercepting assembly 75 includes a fixed shaft 751 fixedly installed on the side wall of the inner cavity of the accommodation groove 712, and a connecting piece 752 is rotatably sleeved on the circumferential outer wall of the fixed shaft 751. The connecting piece 752 and the side wall of the inner cavity of the accommodation groove 712 are elastically connected by a torsion spring 753. The bottom surface of the connecting piece 752 is fixedly installed with a blocking plate 754, and a pair of clamping holes 755 are formed in the bottom surface of the blocking plate 754. The slide column body 711 is vertically embedded and elastically installed with a clamping bead 756.

[0028] Specifically, as shown in Figure 8 The initial state of the hollow slide column 71 is shown. During the irrigation process, the water pressure fluctuation in the pipeline 2 can be significantly reduced due to the arrangement of the energy accumulator in the pipeline 2. However, there will still be water pressure fluctuation in the pipeline 2. At this time, by arranging the buffer assembly 7, the remaining water pressure fluctuation can be buffered, further relieving the phenomenon of pipeline 2 burst, and the phenomenon of nozzle 6 damage and uneven sprinkling, as follows: Case one: the water pressure fluctuation in the pipeline 2 is within the working range of the accumulator, when the water pressure in the pipeline 2 increases, the water will exert pressure on the blocking plate 754, since the applied pressure is not enough to make the clamping bead 756 retract downward, therefore, the clamping bead 756 and the clamping hole 755 are still in the clamping state, the hollow slide rod 71 moves in the slide groove 53 as a whole under the action of the water pressure, moving away from the pipe body 41, which is equivalent to increasing the volume of the pipe body 41, achieving the effect of pressure relief, when the water pressure continues to increase, the hollow slide rod 71 continues to move in the slide groove 53 as a whole under the action of the water pressure, moving away from the pipe body 41, at this time, the water will flow into the water collecting box 302 through the water outlet 52 and the water permeable hole 73 for recycling, this setting is equivalent to increasing the water outlet path, which is equivalent to reducing the water pressure in the pipeline 2, protecting the pipeline 2 and the sprinkler 6, when the water pressure in the pipeline 2 returns to the normal value or decreases, the hollow slide rod 71 is reset under the elastic force of the spring one 72, ready for the next use.

[0029] Case two: as shown in Figures 9-10 , when the water pressure fluctuation in the pipeline 2 is outside the working range of the accumulator, the accumulator cannot play the role of pressure regulation, at this time, under the action of the water pressure, the hollow slide rod 71 moves in the slide groove 53 as a whole under the action of the water pressure, moving away from the pipe body 41, which is different from case one, since the water pressure at this time is enough to make the clamping bead 756 retract downward, therefore, the clamping relationship between the clamping bead 756 and the clamping hole 755 is released, further enabling the connecting piece 752 and the blocking plate 754 to be flipped on the fixed shaft 751, so that a large gap appears between the blocking plate 754 and the slide rod main body 711, a large amount of water can flow out of the gap and into the water collecting box 302 for recycling, another part of the water will still flow into the water collecting box 302 through the water permeable hole 73 and the water outlet 52 for recycling.

[0030] As shown in Figure 4 , the above two cases will not compress the spring one 72 to a large extent, therefore, the teeth on the rack one 74 will not contact the blocking assembly 8, unable to drive the blocking assembly 8 to block the water outlet hole 42, which will not affect the water flow into the sprinkler 6, further not affecting the normal sprinkling of the sprinkler 6.

[0031] With the above setting, whether the water pressure is within the working range of the accumulator or not, the water pressure in the pipeline 2 and the water pressure near the sprinkler 6 can be reduced through the buffer assembly 7, reducing the probability of pipeline 2 bursting and sprinkler 6 damage, protecting the pipeline 2 and the sprinkler 6.

[0032] In order to solve the technical problems of the sprinkler 6 being blocked, increasing the power consumption of the water pump, and the uneven sprinkling of the sprinkler 6 and the bursting of the pipeline 2, as shown inFigure 4 , Figure 6 and Figures 11-14 As shown, the following preferred technical solutions are provided: like Figure 6 As shown, the nozzle 6 includes a nozzle body 61. A pair of limiting members 62 are symmetrically fixedly installed on the circumferential side wall of the nozzle body 61. Limiting grooves 63 are formed on the limiting members 62, and a limiting relationship can be formed between the limiting grooves 63 and the limiting posts 10.

[0033] like Figure 4 , Figure 7 and Figures 11-12 As shown, the sealing assembly 8 includes a baffle 81 slidably installed in the cavity 43. A rack 82 is fixedly installed on the side wall of the baffle 81. A pair of mounting ears 83 are fixedly installed on the side wall of the inner cavity of the pipe body 41. A gear 84 is rotatably installed on the mounting ears 83. The gear 84 is meshed with the rack 82 and the rack 84 respectively. When the hollow sliding column 71 moves, it will drive the baffle 81 to move through the rack 84, the gear 84 and the rack 82, thereby achieving the sealing effect on the water outlet 42.

[0034] like Figures 13-14 As shown, the flipping assembly 20 includes a pair of mounting ears 201 fixedly installed on the side wall of the tube body 41. A swing arm 202 is rotatably mounted on both mounting ears 201. The swing arm 202 and the mounting ears 201 are elastically connected by a torsion spring 203. A clamping ring 204 is vertically slidably mounted on the distal end of the swing arm 202. A load-bearing rod 220 is also fixedly installed on the side wall of the swing arm 202. An electromagnet 230 is fixedly mounted on the top surface of the load-bearing rod 220. A permanent magnet 240 is fixedly mounted on the side wall of the clamping ring 204 facing the electromagnet 230. Aligned with the permanent magnet 240, a lever 205 is fixedly mounted on the side wall of the swing arm 202 near the mounting ear 201. A telescopic plate 206 is slidably mounted in the inner cavity of the mounting groove 44. The lever 205 and the telescopic plate 206 can form a limiting relationship. The bottom surface of the telescopic plate 206 and the side wall of the inner cavity of the mounting groove 44 are elastically connected by a spring 207. A permanent magnet 208 is fixedly mounted on the bottom surface of the telescopic plate 206. An electromagnet 209 is fixedly mounted on the side wall of the inner cavity of the mounting groove 44, and the permanent magnet 208 and the electromagnet 209 are aligned. Figure 7 As shown, a positioning seat 210 is fixedly installed on the side wall of the tube body 41.

[0035] like Figure 4 , Figures 11-12As shown, the installation assembly 9 includes a threaded sleeve 91 rotatably installed in the inner cavity of the water outlet 42. A sealing ring 93 is rotatably installed on the outer circumferential wall of the threaded sleeve 91, and the sealing ring 93 is fixedly installed on the bottom surface of the pipe body 41. The threaded sleeve 91 and the rack 82 are movably connected by a connecting rod 92.

[0036] Specifically, such as Figure 4 As shown, when the pressure value detected by the water pressure sensor 40 is greater than the set threshold, and the pressure value remains unchanged for a long time or rises slowly for a long time, it indicates that the nozzle 6 is blocked. At this time, the electromagnet 77 is energized, so that the electromagnet 77 attracts the permanent magnet 76, which in turn causes the hollow slide column 71 to move away from the tube 41 in the slide groove 53 and compress the spring 72 to the maximum extent, so that the gear 84 and the rack 74 are in a meshing state. When the hollow slide column 71 moves, it will drive the inner cavity of the baffle 81 water outlet 42 to move through the rack 74, gear 84 and rack 82. When the baffles 81 on both sides move into place at the same time, they will block the water outlet 42, so that water will not enter the nozzle 6 through the water outlet 42. This means that when the nozzle 6 is replaced, no water will leak out, which saves water resources. During the movement of the baffle 81, the connecting rod 92 will drive the threaded sleeve 91 to rotate in the inner cavity of the water outlet 42. At this time, since the limiting groove 63 and the limiting post 10 form a limiting relationship, the threaded sleeve 91 rotates in the opposite direction on the nozzle 6, causing the nozzle 6 to gradually come off the threaded sleeve 91, so that the nozzle 6 can be directly removed from the threaded sleeve 91, which serves as the basis for subsequent replacement of the nozzle 6. After the baffles 81 on both sides have sealed the water outlet 42, as Figure 14As shown, the electromagnet two 209 is powered, so that the electromagnet two 209 generates an attractive force on the permanent magnet two 208, so that the telescopic plate 206 is retracted into the inner cavity of the mounting groove 44, and then the limiting relationship between the telescopic plate 206 and the push piece 205 is released, under the elastic force of the torsion spring two 203, the swing arm 202 starts to turn with the nozzle 6, when the swing arm 202 contacts the positioning seat 210, it indicates that the swing arm 202 is turned to the position, at this time, the electromagnet three 230 is powered, so that the electromagnet three 230 attracts the permanent magnet three 240, and then the clamping ring 204 moves on the swing arm 202 with the spare nozzle 6 towards the direction close to the threaded sleeve 91, until the spare nozzle 6 abuts against the threaded sleeve 91, at this time, the electromagnet one 77 is powered in the opposite direction, so that the electromagnet one 77 generates a repulsive force on the permanent magnet one 76, and then the hollow slide column 71 moves in the sliding groove 53 towards the direction close to the pipe body 41, in the process of moving, the hollow slide column 71 drives the baffle 81 to move outside the inner cavity of the water outlet hole 42 through the rack one 74, the gear 84 and the rack two 82, until the two baffles 81 are completely reset, at this time, the water outlet hole 42 is in the passage state, in the process of resetting the baffle 81, the threaded sleeve 91 is rotated in the positive direction in the inner cavity of the water outlet hole 42 through the connecting rod 92, at this time, due to the limiting relationship between the limiting groove 63 and the limiting column 10, the threaded sleeve 91 is rotated in the positive direction on the nozzle 6, and the nozzle 6 is gradually screwed on the threaded sleeve 91, and then the replacement of the nozzle 6 is realized.

[0037] Since the spare nozzle 6 is provided, after the replacement of the nozzle 6 is completed, the turnover assembly 20 does not need to be automatically reset, so that the inspection personnel can timely find that the nozzle 6 is damaged, and after the subsequent inspection personnel installs a new nozzle 6 on the turnover assembly 20 again, the inspection personnel manually resets the turnover assembly 20.

[0038] Through the above setting, even if the nozzle 6 is blocked when the sprinkling device is used for a long time, the blocked nozzle 6 can be replaced in time, without manual replacement, with high automation degree and low personnel working strength; after the new nozzle 6 is replaced, the water pressure in the pipeline 2 is reduced, the probability of bursting of the pipeline 2 is reduced, the load of the water pump is restored to the normal level, which is beneficial to reducing the power of the water pump, plays an energy-saving and environment-friendly role, in addition, good sprinkling effect can be maintained, which is beneficial to crop growth.
