Description

{Fire extinguishing water spray nozzle clamping device for building fire suppression}

The present invention relates to a clamping device for fire extinguishing water spray nozzles for extinguishing building fires. More specifically, when a fire spray nozzle is adjacent, it recognizes this, first clamps the spray nozzle on the side of the device body, and then clamps the fire extinguishing water spray nozzle to the holder body. A structure that achieves a stable clamping operation by inserting into the seating space provided inside the unit and performing secondary clamping. In addition, in the event of a fire, it is immediately recognized and the clamped spray nozzle can be protruded to a standby position for use. This relates to a fire extinguishing water spray nozzle clamping device for fire suppression.

Typically, buildings are equipped with various types of firefighting apparatus or firefighting facilities that can spray water in the event of a fire.

These firefighting appliances and firefighting facilities include fire extinguishers that can be carried or moved by the user to extinguish simple fires, or fixed types that detect fire at the location where the fire occurs and automatically spray water. There are firefighting and extinguishing equipment such as sprinklers.

Firefighting and extinguishing equipment is equipped with a fire nozzle that sprays fire extinguishing liquid to extinguish a fire, and a fire hose that supplies the fire extinguishing liquid necessary for fire suppression is connected to the fire nozzle.

In the firefighting nozzle of Registered Utility Model No. 0226925 (2001.03.30.), a hollow plastic first body consisting of a guide part and a fastening part, a bush inserted and fixed to the inner surface of the fastening part of the first body, and a guide of the first body A rod is inserted into the rod fastening hole formed at one end of the unit and has a disk fastening part at the other end, a disk fastened to the disk fastening part of the rod to control the discharge flow rate of firefighting water, and a hollow body into which the first body is inserted and fixed. It was made to consist of two bodies, and the bush inserted and fixed into the fastening part was fastened to the fire hose.

In the fire extinguishing water spray nozzle clamping device for extinguishing building fires of Registered Patent No. 2361095 (2022.02.07.), the spray nozzle can be fixed to the guide plate installed on the wall using a nozzle supporter and nozzle fixture. It is being done.

However, it is not easy to fix the spray nozzle between the nozzle support and the nozzle fixture to the guide plate, and it is very difficult to separate the fixed spray nozzle from the nozzle support and the nozzle fixture.

Accordingly, conventionally, when the knob protruding in front of the push rod is pressed backward, the pinion gear and the interlocking gear are interlocked by the movement of the rack gear, thereby rotating the rotary holder at a certain angle to clamp the fixing groove of the fixed holder and the rotary holder. Convenience of use was improved by expanding the spacing between grooves to allow the fire extinguishing water spray nozzle to be easily inserted or withdrawn.

However, conventionally, the spray nozzle was fixed or released through a rotational opening operation of the rotary holder. However, when the weight of the spray nozzle exceeds a certain weight, the rotary holder rotates without being properly seated on the fixed holder. Therefore, when gripping the injection nozzle, there is a problem that it is not gripped normally and is placed in a twisted state, which causes overload on the gears and causes damage to the gears.

Accordingly, when the spray nozzle is placed on the side or top of the clamping device, there is a need to develop technology that can automatically recognize it and fix it in the seating position, and have it stand by in a position where it can be used immediately in the event of a fire.

In addition, in the related art, the sizes of the fixed holder and the rotating holder are determined, so there is a problem that spray nozzles of different sizes cannot be substantially clamped.
