Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting dry-type sprinkler heads, in particular to a fire-fighting dry-type sprinkler head with a rotary spraying function. Background Art

[0002] In an environment where the low temperature is less than 4 degrees Celsius or the high temperature is greater than 75 degrees Celsius, fire dry sprinklers will be used to avoid water freezing or water vaporization, which will affect the use of sprinklers.

[0003] A Chinese patent discloses a fast-assembly high-sealing dry-type fire sprinkler, with the publication number CN218652816U, comprising an assembly tube, a yoke arm seat, and a water inlet ring. The yoke arm seat is arranged at the upper end of the assembly tube, and the water inlet ring is arranged at the lower end of the assembly tube. An external threaded sleeve is arranged on the top of the water inlet ring and is threadedly connected to the inner wall of the bottom of the assembly tube. A sealing ring is sleeved on the bottom of the external threaded sleeve. A dust cover is arranged between the yoke arm seat and the assembly tube. During assembly, the guide piece is directly fitted into the assembly tube. The assembly tube and the yoke arm seat are an integrally formed structure, and no additional fixing is required. Finally, the water inlet ring is screwed onto the bottom of the assembly tube, and the external threaded sleeve is screwed into the assembly tube to complete the fixed assembly work. The sealing ring at the bottom of the external threaded sleeve improves the sealing performance. During operation, the glass body is broken when encountering high temperature, the water flow is unrestricted, and the closed flap is pushed open. The closed flap drives the hinge seat to perform hinge activities, and at the same time, the top of the guide piece is further extended into the water outlet channel, and the water flow is sprayed out through the guide piece and the top block, and finally the water splash plate is used to splash open the fire.

[0004] However, it still has the following disadvantages: when the device is in use, water enters from the bottom of the assembly tube and is discharged from the top of the guide piece, and the water hits the splash plate to extinguish the fire downward, which makes the water action range small and the water spraying area small. To this end, we propose a fire dry sprinkler with a rotating spray function to solve this problem. Utility Model Content

[0005] The utility model aims to provide a fire-fighting dry sprinkler with a rotary spraying function to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the utility model provides the following technical solutions: a fire dry sprinkler with a rotary spraying function, comprising a cylinder, a bracket fixedly connected to the outer surface of the cylinder, a glass bulb arranged above the bracket, a shell fixedly sleeved on the outer surface of the cylinder, a water spraying device arranged inside the cylinder, and the water spraying device comprising a water spraying part;

By setting the nozzle, multiple water columns collide with each other to form water mist.

[0012] A further improvement is that a rotating groove is opened on the outer surface of the water outlet pipe, the rotating shell is arranged on the outside of the water outlet pipe, the inner wall of the rotating shell extends into the inside of the rotating groove and is slidingly connected with the inner wall of the rotating groove. When water is sprayed out from the nozzle, the reaction force drives the arc tube and the rotating shell to rotate, thereby expanding the spraying range of the water.

[0013] A further improvement is that a circular groove is opened on the inner wall of the rotating groove, the ball is arranged inside the circular groove, the bottom surface and the inner wall of the rotating shell are rollingly connected with the outer surface of the lower ball and the outer surface of the upper ball respectively, and the rotation speed of the rotating shell is increased by arranging the balls.

After the bottom of the water pipe is connected to the water body, the water body passes through the water outlet pipe and the rotating shell and is sprayed out from the sprinkler head on the arc-shaped pipe. When the water body is sprayed out, the reaction force pushes the arc-shaped pipe to rotate, so that the rotating shell rotates, so that the water body spreads to the surroundings, and the dispersion range of the water body is expanded. At the same time, part of the water body passes through the nozzle on the rotating shell and sprays upward. The water droplets collide to form water mist under the device; by arranging a spring, a connecting plate, a fixing plate and a mounting shell, when the glass bubble breaks, the elastic force of the spring is utilized to move the water pipe, the rotating shell and the arc tube upward, so that the water body is sprayed to the outside of the device; by arranging a baffle, a sealing gasket, an elastic member and a sealing plate, the elastic force of the elastic member is utilized to squeeze the sealing plate and the baffle to seal the bottom of the cylinder; after the glass bubble breaks, the sealing plate and the baffle are separated as the water pipe moves upward, so that the water body enters the cylinder.
