[0028] Refer to Figure 2 , Figure 5 and Figure 6, it also includes a filter water tank 28. The setting of the filter water tank 28 provides an important guarantee for the normal operation of the entire fire-fighting device. It has high filtration capacity, can effectively remove impurities and pollutants in water, ensure the purity of fire-fighting water, and thus improve the fire-extinguishing effect. The bottom end of the fire box 1 is fixedly connected with a transfer pipe 20. Inside the right side of the bottom end of the fire box 1, there is a plug head 21 which is convenient for operators to quickly connect a fire hose for fire-fighting operations. The outer bottom end of the plug head 21 is fixedly connected inside the top end of the transfer pipe 20. In the front side of the plug head 21, there is a connection plate 22 which provides a convenient and stable interface for connecting equipment such as fire hoses. The bottom end of the transfer pipe 20 is detachably connected with a fixed cover 23. The detachable connection design facilitates the maintenance and cleaning of the inside of the transfer pipe 20. This detachable connection is a bolt disassembly. Inside the fixed cover 23, there is a threaded rod 24. The bottom end of the threaded rod 24 is fixedly connected with a turning block 25 which is convenient for operators to easily rotate the threaded rod 24. The top end of the threaded rod 24 is rotatably connected with a filter plate 26 so that the filter plate 26 can more flexibly adapt to the impact of water flow and pressure changes during operation. The outside of the filter plate 26 is fixedly connected with a cleaning ring 27 which effectively cleans the dirt and impurities inside the transfer pipe 20. The front end of the filter water tank 28 is fixedly connected with a water pump two 29. The output end of the water pump two 29 is fixedly connected with a delivery pipe 30. The outside of the cleaning ring 27 is in contact with the bottom end of the plug head 21. The outside of the cleaning ring 27 is slidably connected inside the transfer pipe 20. The front end outside of the delivery pipe 30 is fixedly connected inside the rear side of the transfer pipe 20.
[0029] Working principle: First, when it is necessary to pull out the fire hose 9, the fire hose 9 moves on the fire hose reel 8. This process will drive the pulley 19 to rotate outside the rotating rod 18. This design makes the pulling of the fire hose 9 more convenient and significantly reduces the force required to pull the fire hose 9.
[0030] Moreover, when pulling the fire hose 9, the rotating rod 18 will drive the movable block 17 to slide inside the movable hole 14. During this process, the strong spring 16 will be stressed. After the strong spring 16 is stressed, it will generate a resilience force, which can provide power for subsequent restoration. At the same time, the movement of the movable block 17 can reduce the risk of damage caused by excessive instantaneous pulling force and effectively extend the service life of the fire hose.
[0031] Then, when pumping water with the assistance of the filter water tank 28, after the second water pump 29 is started, water begins to be transmitted inside the conveying pipe 30, then reaches the inside of the transfer pipe 20, and then is conveyed from the inside of the transfer pipe 20 into the plug head 21. During this transmission process, impurities in the water will be intercepted by the filter plate 26, so that they cannot reach the inside of the plug head 21 through the transfer pipe 20, ensuring the purity of the water conveyed to the plug head 21, guaranteeing the normal operation of the fire-fighting equipment, and avoiding the situation that when carrying out fire-fighting operations in areas with poor water quality, without the interception of impurities by the filter plate 26, the plug head 21 is blocked by impurities, affecting the spraying of fire-fighting water.
[0032] Finally, when it is necessary to remove the impurities, first turn the turning block 25 to drive the threaded rod 24 to move inside the fixed cover 23, and then drive the filter plate 26 to move downward. During this process, the cleaning ring 27 will clean the inside of the transfer pipe 20. When the filter plate 26 descends to be close to the fixed cover 23, the impurities will be flattened, and then the fixed cover 23 is opened by using bolts, and the impurities inside can be taken out, thus ensuring the filtering efficiency of the filter plate 26.
[0033] For example, after long-term use, a large amount of impurities may accumulate on the filter plate 26. If not cleaned in time, it will reduce the filtering effect and even cause the filtering function to fail. Through such a design, impurities can be cleaned conveniently and efficiently, and the good performance of the fire-fighting equipment can be maintained.
[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
