Description

Technical Field

[0001] The utility model relates to the technical field of fire sprinkler heads, in particular to a fire sprinkler head with uniform spraying. Background Art

[0002] Fire sprinkler heads are used in fire sprinkler systems. When a fire occurs, water is sprayed out through the sprinkler head splash plate to extinguish the fire. The glass sphere of the fire sprinkler head is filled with an organic solution with a high thermal expansion coefficient. At room temperature, the outer shell of the sphere can withstand a certain supporting force to ensure the sealing performance of the sprinkler head. When a fire occurs, the temperature of the organic solution rises and expands until the glass body breaks, and the ball seat and seal lose support and are washed away by the water flow, thereby starting to spray water to extinguish the fire.

[0003] In the prior art, the water spraying direction of the fire sprinkler head is fixed and there are many spraying dead angles. Not only is the spraying range small, but the spraying is not uniform, and the spraying effect is poor and not practical. Utility Model Content

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a fire sprinkler head with uniform spraying, including a fixed sleeve and a rotating bin, the fixed sleeve is arranged on the outside of the rotating bin, the bottom end of the fixed sleeve is fixedly connected with an annular limit plate, the outer wall of the rotating bin close to the top is sleeved with a fixedly connected limit slider, the top of the fixed sleeve is fixedly connected with a fixed plate, the top of the fixed plate is fixedly connected with a water inlet pipe, the bottom end of the water inlet pipe extends through the inside of the fixed sleeve, the inner bottom of the rotating bin is fixedly connected with a blocking column, the top end of the blocking column extends through the inside of the water inlet pipe and is slidably connected;

[0006] Two brackets are fixedly connected to the bottom of the fixed plate and on both sides of the fixed sleeve, and the bottom ends of the two brackets are fixedly connected to a base. A thermosensitive glass tube is arranged on the top of the base. When a fire occurs, the thermosensitive glass tube will automatically melt. A plurality of rotating spray assemblies are arranged around the outer wall of the rotating bin.

[0007] Preferably, the outer side wall of the rotating bin is movably connected to the inner side wall of the annular limiting plate, and the outer side wall of the limiting sliding block is movably connected to the inner side wall of the fixing sleeve.

[0008] Preferably, the plurality of rotating jet assemblies all include a water spray pipe, one end of which is fixedly connected to the outer wall of the rotating bin, and one side of the surface of the water spray pipe is fixedly connected to a plurality of first nozzles, and high-pressure water is sprayed from the first nozzles to generate a reverse force on the water spray pipe, thereby driving the rotating bin to rotate.

[0009] Preferably, the bottom of the rotating bin is in an inverted truncated cone shape, and a plurality of second nozzles are fixedly connected around the bottom end of the rotating bin and the truncated cone-shaped inclined surface of the rotating bin. When the second nozzles spray water, the second nozzles throw the water to the surroundings as the rotating bin rotates, which not only makes the spraying range wider but also more uniform.

[0010] Preferably, the top of the base is fixedly connected to a second fixing groove, the bottom center of the rotating bin is fixedly connected to a first fixing groove, the top end of the thermosensitive glass tube is installed inside the first fixing groove and tightly against the inner top of the first fixing groove, and the bottom end of the thermosensitive glass tube is installed inside the second fixing groove and tightly against the inner bottom of the second fixing groove.

[0012] The beneficial effects of the utility model are as follows:

[0013] The utility model provides components such as a rotating bin, a blocking column and a thermosensitive glass tube. When the thermosensitive glass tube melts, the rotating bin loses support and slides downward from the inside of the fixed sleeve under the pressure of water. High-pressure water flows into the fixed sleeve and the rotating bin from the water inlet pipe. High-pressure water is sprayed from a first nozzle on one side of a plurality of water spray pipes and generates a reaction force, thereby driving the rotating bin to rotate. The bottom end of the rotating bin and a plurality of second nozzles on the truncated cone-shaped inclined surface of the rotating bin can rotate with the rotating bin while spraying water. The rotation can make the water flow area sprayed by the second nozzle larger and more uniform without dead angles, which is more practical. BRIEF DESCRIPTION OF THE DRAWINGS
