when the device works, the second impeller 26 is arranged on the second rotating shaft 251, after the device is impacted by water flow, the second rotating shaft 251 is driven by the second impeller 26 to rotate, so that the cotton rope 212 positioned in the first through hole 211 starts to twist, the cotton rope 212 has certain elasticity, after the cotton rope 212 is twisted to a certain degree, the cross rod 215 at the other end of the cotton rope 212 jumps on the wave bulge 216 and enters the next gap, in the jumping process of the cross rod 215, the twisting moment on the cotton rope 212 is released through the rotation of the cross rod 215, meanwhile, in the jumping process of the cross rod 215, the cotton rope 212 shakes and contacts the inner wall of the first through hole 211 to remove impurities attached to the inner wall of the first through hole 211, so that the first through hole 211 is prevented from being blocked, and simultaneously, when the cotton rope 212 is twisted, fibrous substances entering the first through hole 211 are collected, so that the first through hole 211 or the second through hole 213 is prevented from being blocked by the substances, meanwhile, after the cotton rope 212 is used for a long time, the cleaning of the first through hole 211 by the cotton rope 212 can be recovered by replacing a new cotton rope 212.

As an embodiment of the present invention, an installation rod 27 is installed on one end of the second rotating shaft 251, which is located outside the mesh plate 241; the mounting rods 27 are distributed uniformly around the center line of the second rotating shaft 251; the long needles 271 are uniformly arranged on the mounting rod 27;

during operation, when the second rotating shaft 251 starts to rotate, the mounting rod 27 mounted on the second rotating shaft 251 starts to rotate synchronously, and meanwhile, as the long needles 271 are uniformly mounted on the mounting rod 27, impurities in the water flow can be blocked to a certain extent in the process that the mounting rod 27 rotates along with the second rotating shaft 251, particularly the mounting rod 27 is in a fiber shape, and long substances can be easily wound on the long needles 271 to be collected, so that the situation that the impurities continue to move forward along the water flow to cause blockage of the first through hole 211, the second through hole 213 or the spray head, and normal irrigation work is influenced is avoided.

The specific working process is as follows:

when the irrigation device works, when a field needs to be irrigated, the water pump, the main water supply pipe, the branch water supply pipe, the monitoring device and the spray head are installed in sequence, then the water pump is started to supply water through the water pump, then the water flow passes through the monitoring device and is sprayed out through the spray head, the irrigation on the field is completed, meanwhile, when the water flow passes through the monitoring device, the impeller I22 positioned in the main body 1 is impacted by the water flow and starts to rotate, after the impeller I22 starts to rotate, the ring 23 and the impeller I22 are fixedly connected together, therefore, the ring 23 and the impeller I22 synchronously start to rotate, when the ring 23 starts to rotate, the magnetic block 231 arranged on the ring 23 starts to periodically rotate, when the magnetic block 231 rotates to the position just opposite to the cavity I33 along with the ring 23, the repulsion force between the magnetic block 231 and the extrusion block I3 reaches the maximum, the extrusion block I3 extrudes the sensor I32, a primary signal is sent to the controller, and meanwhile, the second extrusion block 4 in the third installation cavity in the main body 1 is extruded by the flexible plate 44 extruded by the water flow pressure to generate an extrusion effect on the second sensor 41, so that the second sensor 41 sends a signal; when water flows through the monitoring device, the pressure of the water flow acts on the flexible plate 44 at the upper opening of the cavity III 43, the flexible plate 44 slightly sinks inwards under the pressure of the water flow, and the cavity III 43 is filled with hydraulic oil, so that the second extrusion block 4 is extruded by the hydraulic oil in the cavity II 42; in the using process, water flow enters the first rotating shaft 21 through the first through hole 211 in the first rotating shaft 21 and is finally sprayed out from the second through hole 213 in the rectangular groove 214, the contact position of the first rotating shaft 21 and the first fixing rod 2 is cleaned, and meanwhile, as the mesh plate 241 is installed on the conical plate 24, impurities in water are intercepted; the second impeller 26 is arranged on the second rotating shaft 251, so that the second impeller 26 starts to rotate after the second impeller 26 is impacted by water flow in the monitoring device, and meanwhile, in the rotating process of the second impeller 26, the second rotating shaft 251 starts to rotate synchronously because the second impeller 26 is arranged on the rotating shaft, and the driving lever 252 is driven to rotate through the rotation of the second rotating shaft 251; the second impeller 26 is arranged on the second rotating shaft 251, and after the second rotating shaft 251 is impacted by water flow, the second rotating shaft 251 is driven by the second impeller 26 to rotate, so that the cotton rope 212 positioned in the first through hole 211 starts to twist, after the cotton rope 212 is twisted to a certain degree, the cross rod 215 at the other end of the cotton rope 212 jumps over the wave bulge 216 and enters the next gap, in the jumping process of the cross rod 215, the twisting moment on the cotton rope 212 is released through the rotation of the cross rod 215, and meanwhile, in the jumping process of the cross rod 215, the cotton rope 212 shakes to contact the inner wall of the first through hole 211, so that impurities attached to the inner wall of the first through hole 211 are removed; when the second rotating shaft 251 starts to rotate, the mounting rod 27 mounted on the second rotating shaft 251 starts to rotate synchronously.
