[0007] A fixed head, a plug is inserted at the bottom of the fixed head, a conical filter is arranged inside the fixed head, the filter is located above the plug, a fixed shaft is fixedly connected to the top of the filter, a fixed frame is fixedly connected to the circumference of the fixed shaft, and a plurality of inclined driving plates are fixedly connected to the bottom of the fixed frame;

[0008] A brush plate for cleaning the surface of the filter screen is fixedly connected to the inner circumferential wall of the fixed head, and a connected slag collecting box is fixedly connected to one side of the fixed head. The brush plate is located on one side of the slag collecting box. By installing a rotatable filter screen in the fixed head, the product can filter the fire water through the filter screen during use to avoid impurities blocking the channel. At the same time, the rotating filter screen cooperates with the brush plate to concentrate the impurities into the slag collecting box to avoid affecting the use of the filter screen.

[0009] A control mechanism is provided below the plug to control the water spray.

[0010] As a further scheme of the utility model, the control mechanism includes a hexagonal sleeve, which is fixed on the circumference of the fixed head. The bottom of the hexagonal sleeve is fixedly connected to two brackets. A support sleeve is fixedly connected between the bottoms of the brackets. A top plate is slidably connected inside the support sleeve. A temperature-sensitive glass column is arranged between the top of the top plate and the bottom of the plug. The bottom of the support sleeve is threadedly connected with a top screw for adjusting the position of the top plate. The top screw is locked, and the top screw pushes the top plate to squeeze the temperature-sensitive glass column, and then the plug is pushed to the bottom of the fixed head through the temperature-sensitive glass column. When a fire occurs, the temperature-sensitive glass column explodes due to the heat, and then the plug is flushed open under the action of water pressure, thereby allowing the fire water to be discharged.

[0011] As a further solution of the utility model, a plurality of L-shaped support frames are fixedly connected to the bottom of the support sleeve, and a horizontal splash plate is sleeved between the plurality of support frames.

[0016] As a further solution of the utility model, the support frame is connected to a rotating sleeve for circular rotation, and the rotating sleeve is in contact with the bottom of the horizontal splash plate.

[0017] In the present application, when in use, the product is fixed as a whole on the fire-fighting pipe through the fixed head, and then the temperature-sensitive glass column is placed between the plug and the support sleeve, and then the top screw is locked. The top screw pushes the top plate to squeeze the temperature-sensitive glass column, and then the plug is pressed against the bottom of the fixed head through the temperature-sensitive glass column. When a fire occurs, the temperature-sensitive glass column explodes due to heat, and then the plug is flushed open under the action of water pressure, thereby allowing the fire-fighting water to be discharged. When the fire-fighting water in the fixed head passes through multiple inclined driving plates during the rapid discharge process, the filter screen fixed under the driving plate rotates by impacting the driving plates, and the filter screen filters the fire-fighting water while interacting with the brush The brush plate contacts the filter, and the brush plate sweeps the impurities on the filter screen and enters the slag collecting box after being guided by it, so as to prevent the impurities from clogging the filter screen and facilitate the circulation of fire water. The fallen fire water is dispersed to various places under the action of the horizontal splash plate, thereby achieving the effect of fire extinguishing. At the same time, when the water flows through the curved splash plate, part of the fire water is thrown to a farther place after being guided by the curved splash plate, thereby increasing the fire extinguishing range. Part of the water flows hits the vertical plate after passing through the water guide plate, and the vertical plate, the curved splash plate and the horizontal splash plate rotate, and then under the action of centrifugal force, the fire water is thrown to a farther place, thereby increasing the fire extinguishing range.
