Fire-fighting spray head protection device

Abstract

The invention relates to the technical field of fire-fighting equipment, and discloses a fire-fighting spray head protection device. The device comprises a yoke arm column, wherein a lower connecting seat is fixedly installed at the bottom of the yoke arm column; a clamping groove is formed in the middle of the top of an inner cavity of the yoke arm column and is used for placing an upper clamping seat; and a glass tube is fixedly installed at the bottom of the upper clamping seat. Double-layer overlapped grids are arranged at the outer side of the glass tube, and fireproof rubber strips are additionally arranged between the grids, so that the buffer performance between the grids is improved; when foreign matter impacts the grids, the grids form double-layer flexible protection on the glass tube, the situation that the glass tube is broken due to the foreign matter is avoided, and the maintenance cost is reduced; and the rubber strips and the grids can effectively increase the deformation energy of a protective cover, external huge impact energy can be converted into deformation energy through the deformed grids, energy of impact points is transmitted to other grids, the damage degree of the single impact point is reduced, and the protective effect of the protective cover is improved.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a protective device for a fire-fighting sprinkler head. Background technique [0002] For indoor safety considerations, fire sprinklers are generally installed on the roof. The structure of this fire sprinkler includes a choke column, a glass tube and a splash plate at the bottom of the choke column. The inside of the glass tube is filled with thermal expansion coefficient The high organic solution is generally filled with red kerosene liquid inside, and the upper and lower ends of the glass tube are equipped with a card holder. The outer shell of the glass tube has a certain supporting force. When a fire occurs, the temperature of the internal organic solution will rise and expand. , until the glass is broken, the supporting force of the upper and lower decks disappears, so that the high-pressure water flow inside the water pipe flows out, splashes on the splash ...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the use of the existing fire sprinkler head proposed in the background technology, the present invention provides a fire sprinkler head protection device, which is equipped with the protection device for glass tubes of the sprinkler head from breaking, reducing the loss of water resources, and avoiding fire hazards. The advantages of less water when using water and reducing the maintenance cost of replacing the sprinkler head solve the problems raised in the above background technology
