Problems solved by technology

[0002] Existing fire extinguishing nozzles used in the fire protection industry include temperature-sensitive nozzles and open-type centrifugal nozzles. The former temperature-sensitive nozzles use glass bubbles at 57-100°C to absorb the temperature of fire combustion, causing the liquid in the glass bubbles to expand. When the critical point is reached, it explodes, and at the same time, the fulcrum of the valve plug is released, and the valve plug falls off to spray water to extinguish the fire. Its disadvantage is that the time of bubble explosion is obviously lagging behind the fire, and it is not suitable for fire extinguishing in tall and large spaces, because the height of the temperature-sensitive bubble nozzle is limited. , so the indoor high air temperature is difficult to reach the explosion temperature of the glass bubble in the event of a fire, so as to achieve timely fire extinguishing
[0003] Centrifugal sprinkler head, detector and electromagnetic valve are separately installed devices. As a sprinkler head, the reaction force is generated after the water is sprayed from the two side nozzles, so that the sprinkler head rotates and sprinkles water. The rotating parts of the sprinkler head are easily damaged by water. If it is not used for a long time, the nozzle will not turn when it is used, which will affect the sprinkler fire
In addition, its water spraying surface is also smaller

Embodiment 1

[0024] Embodiment 1: Please refer to Figure 1, Figure 2, Figure 3, Figure 4, Figure 5, and Figure 8. The main shaft 1 of the present invention is connected to the water supply pipe 11 of the system, and the lower end is connected to the bracket 3, the device body 5, and the splash plate 4 A rigid structure is formed, and an opening and closing mechanism 6 is installed in the middle of the device body 5. The opening and closing mechanism 6 compresses the sealing ring at the lower end of the main shaft 1 upwards, and the motor 10 controls the opening and closing of the opening and closing mechanism 6.

[0025] The water distribution hole 12 of the splash plate 4 around the flat mouth of the device body 5 is 360 degrees from the inside to the outside, and the water distribution hole 12 on the splash plate 4 is strip-shaped, and there are multiple transverse cuts on the left and right sides that are trapezoidal. The water surface 13, in this embodiment, a plurality of water-distrib...

Embodiment 2

[0029] Embodiment 2: As shown in Figure 6, its working process is automatic opening, and it cannot complete the closing action by itself. The water plug 15 under the main shaft 1 is driven by the motor 10 to rotate the gear lock 16. When the 90-degree opening of the gear lock 16 rotates to the ejector rod 17 When the protruding pin 18 is turned on, the push rod 17 falls off. At this time, the water plug 15 is quickly opened and the water is sprayed from the splash plate 4. Its automatic opening and closing mechanism is a snap spring lock switch, and the electric signal output by the fire is controlled by the motor 10. Drive the gear lock 16 to rotate to realize the function.

Embodiment 3

[0030] Embodiment 3: As shown in Figure 7, its working process is automatic opening and closing (opening or closing). The motor 10 uses the gear 20 to drive the rack 19 to reciprocate up and down to open and close the water plug 15 at the bottom of the main shaft 1, which is executed in the event of a fire. Open the opening and closing mechanism 15 to spray water and put out the fire.

[0031] This fire extinguishing device can not be provided with the opening and closing mechanism 6 inside itself, and an electromagnetic valve is set on the front end water supply pipe 11 of the fire extinguishing device 21 in addition. The valve supplies water to extinguish the fire.

Abstract

The automatic spraying fire extinguisher with detecting and alarming functions as one kind of fire extinguishing apparatus includes a main shaft, an assembly, a shallow water tray, a starting mechanism and a fire detector. It has the fire detector, the starting mechanism and the fast nozzles combined integrally; the main shaft with lower water outlet communicated hermetically with the starting mechanism and rack connected to the assembly and the shallow water tray; the shallow water tray set in parallel with the assembly; the starting mechanism capable of reciprocating vertically inside the shallow water tray and connected to a motor; and the fire detector in a casing connected to the lower part of the assembly. The present invention is suitable for use in large building.

Description

technical field [0001] The invention relates to a fire extinguishing device, in particular to a rapid fire extinguishing device with functions of detection, alarm and automatic opening and closing, which is suitable for installation in large-space buildings. Background technique [0002] Existing fire extinguishing nozzles used in the fire protection industry include temperature-sensitive nozzles and open-type centrifugal nozzles. The former temperature-sensitive nozzles use glass bubbles at 57-100°C to absorb the temperature of fire combustion, causing the liquid in the glass bubbles to expand.
