Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a fire-fighting sprinkler device. Background Art

[0002] Fire sprinkler systems are widely used as fixed firefighting devices. Their low cost and high firefighting efficiency make them widely used in building fire protection. Fire sprinkler heads are an integral part of a building's fire protection system, automatically spraying water when a fire breaks out to control or extinguish the initial fire.

[0003] After searching, it was found that most of the existing fire sprinkler equipment uses fixing bolts to fasten the glass balls when installing them. However, the clamping force borne by the glass balls cannot be ensured during the tightening process, resulting in damage to the glass balls due to strong clamping. At the same time, using suitable water expansion trays in different scenarios can enhance the efficiency of fire extinguishing.

[0004] Therefore, those skilled in the art provide a fire sprinkler device to solve the problems raised in the above background technology. Utility Model Content

[0016] Furthermore, the clamping column is clamped into the groove;

[0017] Through the above technical solution, the water expansion tray can be positioned at the bottom of the equipment by inserting the clamping column into the groove so as to be quickly fixed.

[0018] Furthermore, the fixing bolt passes through the first screw hole and is threadedly connected to the inside of the second screw hole;

[0019] Through the above technical solution, the water expansion tray can be fixed to the bottom of the equipment by passing the fixing bolt through the first screw hole and being threadedly connected to the inside of the second screw hole, thereby preventing the water expansion tray from falling off and facilitating its replacement.

[0020] Furthermore, a plurality of water troughs are provided at equal intervals on the upper end of the water expansion tray;

A plurality of water troughs 12 are equidistantly provided at the upper end of the water expansion tray 11. By equidistantly providing a plurality of water troughs 12 at the upper end of the water expansion tray 11, it is convenient for water to flow evenly, thereby improving the efficiency of fire extinguishing.

[0035] The loosening mechanism 9 includes a ball seat 901, which is fixedly arranged between the two brackets 7 and close to the lower end thereof. A sliding block 902 is slidingly arranged inside the ball seat 901, and a spring 903 is fixedly arranged at the lower end of the sliding block 902. Positioning holes 905 are provided on both sides of the sliding block 902 close to the upper end thereof.

The fixing bolt 1005 passes through the first screw hole 1003 and is threadedly connected to the second screw hole 1004. By passing the fixing bolt 1005 through the first screw hole 1003 and is threadedly connected to the second screw hole 1004, the water expansion tray 11 can be fixed to the bottom of the equipment, thereby preventing the water expansion tray 11 from falling off and facilitating its replacement.

[0037] Working principle: When the fire sprinkler equipment is used, first clamp the glass ball 8 in the card slot 904 and make the sealing valve 6 block the water outlet 4. Then, the sliding block 902 is acted upon by the spring 903 to give the glass ball 8 the maximum clamping force. The positioning column 906 is used to pass through the positioning hole 905 to prevent the impact of the flowing water from affecting the spring 903 and causing the sealing valve 6 to leak, thereby achieving the installation of the maximum bearing clamping force for the glass ball 8 and ensuring the stability of the glass ball 8. Then, the water expansion tray 11 is placed at the bottom of the equipment, and the card column 1001 is clamped into the groove 1002. Then, the fixing bolt 1005 is used to tighten it from the bottom of the water expansion tray 11. This allows the water expansion tray 11 of various shapes to be replaced so that it is suitable for different environments. Then, the mounting stud 2 is installed to the designated position to achieve the installation of the equipment, thereby improving the practicality and applicability of the equipment.
