The other end of the rotating rod 19 extends out of the water tank 5 and is connected to the reduction gearbox 8.

[0024] To prevent impurities in the water flow from entering and accumulating inside the water tank 5, causing corrosion of the tank 5 and its internal parts, and affecting the rotation and operation of the impeller 12, a filter screen 13, a jet gun 23, a jet pipe 21, a first sprocket, and a second sprocket are also included. The filter screen 13 is located between the water inlet channel 10 and the water outlet channel 11, and in front of the impeller 12. The water tank 5 is equipped with a cleaning box 24 for cleaning impurities attached to the filter screen 13. An avoidance passage 14 is provided on the inner wall of the water tank 5.

One end of the jet pipe 21 is located within the sliding rod 15, and the other end is located within the cleaning box 24. The jet gun 23 is rotatably mounted at the end of the jet pipe 21 and located within the cleaning box 24. The other end of the jet pipe 21... The system includes a first flexible hose 21 at one end, with the other end connected to an external water pump. A second flexible hose 25 is also provided inside the cleaning box 24 to extract impurities from the jet. One end of the second flexible hose 25 is connected to the cleaning box 24, and the other end is connected to an external suction pump. A sliding rod 15 is connected to a top pressure plate 16, which is horizontally positioned. A sealing box 9 covers the sliding rod 15 and the top pressure plate 16 on the water tank 5. A drive shaft 18 is rotatably mounted inside the sealing box 9, and an eccentric cam 17 is mounted on the drive shaft 18. A first sprocket is mounted on a rotating rod 19, and a second sprocket is mounted on the drive shaft 18. A chain is wound between the first and second sprockets. A water-passing seat 30 is provided on the jet gun 23, and a jet rod 27 is rotatably mounted on the jet pipe 21. The jet rod 27 is connected to the water-passing seat 30 to drive the jet gun 23 to rotate. A servo motor is provided inside the jet pipe 21 to drive the jet rod 27 to rotate.

[0025] To prevent impurities from being easily scraped off and the filter screen 13 from being easily scratched when the cleaning box 24 slides downward, a screw 29 and a worm gear 28 are also included. The screw 29 is rotatably mounted on the jet tube 21. A fixing block is provided at the upper end of the cleaning box 24. The screw 29 passes through the fixing block and is threadedly driven by the fixing block. A sliding channel 26 is provided on the cleaning box 24 for the jet tube 21 to slide. The worm gear 28 is mounted on the screw 29 through a clutch 291 and is located inside the jet tube 21. A worm wheel is provided on the jet rod 27, and the worm gear 28 is driven by the worm wheel.

[0026] In order to improve the jetting capability of the jet gun 23, a pressurizing pump (not shown in the figure) is also connected to the jet pipe 21 for pressurizing the incoming water.

[0027] Working principle:

[0028] When in use, when the fire monitor 4 is used for fire extinguishing, water flows through the fire hydrant body, then into the fixed pipe 2, then through the rotating pipe 3, and finally sprays out from the fire monitor 4 to extinguish the fire. Simultaneously, water flows into the water tank 5, enters through the inlet channel 10, rushes towards the impeller 12, causing it to rotate, and then flows out from the outlet channel 11. When the impeller 12 rotates, it drives the rotating rod 19 to rotate, which in turn drives the reduction gearbox 8. The output shaft on the reduction gearbox 8 rotates, driving the drive rod 7 to rotate. The drive rod 7 pulls the swing rod 6 to swing, thereby driving the rotating pipe 3 to rotate. The rotating pipe 3 then drives the fire monitor 4 to rotate, thus achieving automatic swinging of the fire monitor 4 to extinguish fires within its range. This saves manual operation, improves firefighting efficiency, and eliminates the need for manual operation, keeping it away from the fire source and improving the safety of firefighters.

[0029] When water flows through the impeller 12, it is filtered by the filter screen 13, which removes impurities and prevents them from entering the interior, thus avoiding rust and blockage of the impeller 12. When the impeller 12 drives the rotating rod 19 to rotate, it drives the first sprocket to rotate, which in turn drives the second sprocket to rotate. The second sprocket drives the eccentric wheel to rotate, and the rotation of the eccentric wheel causes the sliding rod 15 to slide downward under the action of gravity. During the downward sliding process, the clutch 291 first closes, then the servo motor rotates, which in turn drives the jet rod 27 to rotate. The jet rod 27 drives the worm gear 28 to rotate, which in turn drives the worm wheel to rotate. The worm wheel drives the screw 29 to rotate, and the screw 29 is threadedly driven by the fixed block, causing the cleaning box 24 to slide until it resists the filter screen 13. Then the clutch 291 disengages, allowing the jet rod 27 to continue to drive the jet gun 23 to rotate rapidly. This causes the water pumped into the jet gun 23 to jet onto the filter screen 13, thereby cleaning the impurities on the filter screen 13. Then the suction pump works, continuously drawing water out of the cleaning box, thereby sucking out the impurities. After cleaning one cleaning box position, clutch 291 engages, servo motor reverses, driving screw 29 to reverse, causing the cleaning box to return to its original position and release the resistance with filter screen 13. Then, when the cleaning box slides to the next position, screw 29 rotates, causing the cleaning box to resist the filter screen 13 again. Then clutch 291 is disengaged, jet gun 23 jets onto filter screen 13, and then the impurities are extracted. This process is repeated to clean filter screen 13 to improve its endurance. At the same time, the cleaning box is less likely to scratch filter screen 13, thus extending the service life of filter screen 13.
