the leakproofness of shell 2 and dust cover 17 can further be improved to the rubber layer 18 that sets up to can prevent that the dust in the air from blockking up shower nozzle 10, in addition, through setting up rubber layer 18, can guarantee the relative fixed in position between dust cover 17 and the shell 2, avoid having the slight shake between dust cover 17 and the shell 2, influence the result of use of dust cover 17.

The specific working process is as follows:

when a fire occurs, the fire protection system controls the motor 8 to be started, the output shaft of the motor 8 rotates to drive the steel wire rope 9 to be wound on the output shaft, the other end of the steel wire rope 9 tensions the guide block 7, so that the deformation block formed by the guide block 7 is bent under the action of external force, the overall shape is 1/4 circular arc after the appearance change is stopped, thereby the hose 6 in the guide block 7 is also changed into 1/4 circular arc, the motor 8 decelerates through the worm gear, because the worm gear has the characteristic of self-locking, in the using process, the active driving of the motor 8 is avoided, the worm gear cannot rotate by itself, the shape of the deformed block after deformation is ensured to be stable, meanwhile, the water enters the water inlet pipe 21, the water flow sequentially passes through the rotary joint 1, the rotary box 3, the first water pipe 4, the second water pipe, the hose 6, and finally the water is sprayed out through the spray head 10 and the rotary spray head 22, the water sprayed out by the spray head 10 and the rotary spray head 22 and the deformation block 6 can push the dust cover 17 to form 1/4 When water is sprayed out through the spray head 10, the parabolic correlation law can know that the coverage of the water sprayed out from the spray head 10 is larger, meanwhile, under the action of the reaction force of the sprayed water and the rotary joint 1, the direction of the sprayed water of the deformed spray head 10 is coincident with the tangential direction of the shell 2, the external high-pressure water pump enables the water to generate enough pressure, so that enough reaction force is generated during spraying the water, the reaction force of the sprayed water pushes the shell 2 to integrally rotate, the coverage area of the sprayed water is further enlarged, dead angles are avoided, the rotary spray head 22 with the effects of extinguishing fire and preventing the fire from spreading can also spray the water in a rotating way, as the shell 2 is fixed on the rotary joint 1, the rotary box 3 is also fixed on the rotary joint 1, the filter plate 13 is fixed in the rotary box 3, and when the shell 2 rotates, the rotary box 3 and the filter plate 13 also rotate along with the rotary box, the connecting rod 11 and the blade 12 can not rotate, when water flows through the blade 12, the blade 12 and the filter plate 13 rotate relatively, the blade 12 can ream impurities in the water, the filtered water flows out through the filter hole, when the shell 2 rotates, the rotary box 3 and the magnetic plate 15 also rotate along with the rotary box, the connecting rod 11 and the blade 12 can not rotate, the blade 12 and the magnetic plate 15 rotate relatively, when the magnetic plate 15 rotates, the left blade 12 of the blade 12 is attracted with the left semicircle of the magnetic plate 15, the right blade 12 of the blade 12 is attracted with the right semicircle of the magnetic plate 15, the magnetic plate 15 moves upwards integrally, so that the dredging rod 14 is driven to be inserted into the filter hole, when the magnetic plate 15 rotates again, the left blade 12 of the blade 12 is magnetically repelled with the left semicircle of the magnetic plate 15, the right blade 12 of the blade 12 is magnetically repelled with the right semicircle of the magnetic plate 15, the whole downward motion of magnetic plate 15 to drive dredging rod 14 and extract the filtration pore, magnetic plate 15 can also drive dredging rod 14 at rotatory in-process and continuously do the plug motion by the up-and-down motion, makes the continuous mediation filtration pore of dredging rod 14, prevents that impurity from piling up in the filtration pore, can let impurity by the blade 12 hinge garrulous once more on being pushed up filter 13.
