[0030] It is worth noting that the top of the slot shaft 41 is connected with a plurality of scrapers 47, the plurality of scrapers 47 are in contact with the inner wall of the inner tube 2, because the fire-fighting water in the inner tube 2 may deposit a small amount of scale and impurities in a long time of static state, when the slot shaft 41 rotates, the plurality of scrapers 47 rotate, so that the plurality of scrapers 47 can scrape off the scale and impurities attached to the inner wall of the inner tube 2, so that the scraped scale and impurities are washed out with the water flow, avoiding the influence of the scale and impurities on the smoothness of the fire-fighting water discharge.

[0031] In this embodiment, the slot shaft 41 is connected with the inner tube 2 by rotating clamping through the setting of the trigger mechanism 4, the connection effect is more reliable, when overhauling, after removing the lever 42, the slot shaft 41 can still maintain a reliable connection effect, avoiding the situation of accidental triggering, when a fire breaks out in the room, the rotation of the slot shaft 41 is indirectly triggered by the rupture of the two fuse pieces 45, so as to realize the separation of the inner tube 2 and the slot shaft 41, and then realize automatic water spraying, the setting of the double fuse pieces 45 is more solid compared with a single glass column, thereby avoiding the situation of triggering water spraying due to collision.
