Description

Firefighting water spray nozzle mounting device for fire suppression {WATER SPRAY NOZZLE PLACING APPARATUS FOR FIRE SUPPRESSION}

The present invention relates to a fire-fighting water spray nozzle mounting device for fire suppression.

Buildings are equipped with various types of firefighting devices or firefighting facilities capable of spraying water into an indoor space.

Such firefighting equipment and firefighting facilities are equipped with a mechanism that can be gripped by the user and extinguished a simple fire while moving by the user, such as a fire extinguisher, or a sprinkler that can detect an indoor fire and spray water to the point where the fire has occurred. I'm talking about fire extinguishing equipment.

Firefighting facilities such as sprinklers are generally configured to receive fire extinguishing water supplied from the outside through a pipe and discharge it to the outside through a spray nozzle provided at the end. Through this configuration, the fire extinguishing water is sprayed to the point where the fire has occurred. It is structured so that it can be done. For example, conventional firefighting equipment is configured to discharge extinguishing water to a fire site through a nozzle provided when a fire is detected by the firefighting equipment.

However, the conventional firefighting equipment is only for the main purpose of extinguishing indoor fire, and there is no firefighting equipment for the outer wall of the building. In particular, in the case of gas piping installed on the outer wall of an apartment house, there is a risk of explosion when heated by fire, but there is no firefighting equipment for firefighting and cooling of the gas piping.

Therefore, when the gas pipe is heated by an indoor fire, there is a risk of explosion of the gas remaining in the pipe, and the heated pipe cannot be grasped by the hand of the residents who evacuate through the window, so the evacuation route is inevitably limited for high-rise residents. .

1 to 3, the mounting device according to the present invention includes a clamp 100, a water spray nozzle 200, a distribution pipe 300, a bracket 400, a bridge 500, and a power generation sensor 600. and an on-off valve 700.

The mounting device according to the present invention is to spray water to the gas pipes (GP1, GP2) to prevent heating of the gas pipes (GP1, GP2) due to fire, the water spray nozzle 200 to the gas pipes (GP1, GP2) and a clamp 100 for mounting the distribution pipe 300, a water spray nozzle 200 for spraying supplied water to the gas pipes GP1 and GP2, and a distribution pipe 300 for supplying water. Here, the mounting device is a power generation sensor 600 reinforced to detect the water injection of the indoor sprinkler (S) in response to an indoor fire in the dry preaction valve (V), and a distribution pipe by the electric signal of the power generation sensor 600 It further includes an on-off valve 700 that opens the 300.

More specifically, the power generation sensor 600 installed in the dry preaction valve V and the on/off valve 700 installed in the water supply pipe WP to open the distribution pipe 300, the power generation sensor 600 ) is a rotating blade 610 installed in the discharge pipe (V1) of the dry preaction valve (V) to rotate by hydraulic power of water supply to the indoor sprinkler (S), and generating an electrical signal by the rotating blade 610 It consists of a generator (not shown). As is known, the inside of the dry preaction valve (V) is divided into an inlet pipe and a discharge pipe (V1) based on the clapper. The discharge pipe (V1) communicates with the sprinkler (S), and supports the clapper from being opened by filling nitrogen gas or compressed air therein. Since the rotary blade 610 according to the present invention is built into the discharge pipe (V1), it maintains a stationary state in normal times. Then, when a fire occurs in the room, the sprinkler (S) is opened, and the nitrogen gas or compressed air filled in the discharge pipe (V1) is quickly exhausted through the sprinkler (S). In this process, the air pressure in the discharge pipe V1 is rapidly decreased, and the relatively high water pressure in the water inlet pipe pushes the clapper open and supplies water to the sprinkler S through the discharge pipe V1. In this process, the rotary blade 610 installed in the discharge pipe (V1) rotates with the hydraulic power of water, and a generator interlocked with the rotary blade 610 generates an electrical signal.

On the other hand, when the electric signal is received, the opening/closing valve 700 opens the distribution pipe 300 so that the water spray nozzle 200 sprays water. To this end, the distribution pipe 300 communicates with the dry preaction valve V through the water supply pipe WP, and the on/off valve 700 opens the distribution pipe 300 to the water supply pipe WP. As a result, the mounting device according to the present invention sprays water to the gas pipes GP1 and GP2 through the water spray nozzle 200 immediately upon detecting the operation of the indoor sprinkler S.

The clamp 100, the water spray nozzle 200, the distribution pipe 300, and the bracket 400 configured in the mounting device according to the present invention will be described in more detail.

The reference shaft 110 is disposed between the first gas pipe GP1 and the second gas pipe GP2 arranged side by side, and a portion of the cross section in which the female threaded shaft hole 111 is opened is the concave portion 112 make up In this embodiment, four gas pipes (GP1, GP2) are installed to ride the wall (W) via the fixing table (B), between the first gas pipe (GP1) and the second gas pipe (GP2) located in the middle. The reference shaft 110 is located side by side. The reference shaft 110 has female threaded shaft holes 111 formed on the upper and lower surfaces, respectively, and the concave portion 112 of the present embodiment formed on parts of the upper and lower surfaces has a semicircular shape as shown in FIG. 4 .

The fixing hook 120 is configured to protrude sideways from the top and bottom of the reference shaft 110 so as to detachably surround one side of the outer circumference of the first gas pipe GP1. As shown, the fixing hook 120 has a ring shape with one side open, and one side of the outer circumference of the first gas pipe GP1 is press-fitted through the open side. An adhesive for close contact with the first gas pipe GP1 may be applied to the inside of the fixing hook 120 . Since the fixing hooks 120 each protrude from at least the top and bottom of the reference shaft 110, they form a pair to be placed at the top and bottom.

The free hook 130 is a rotating unit constituting a convex portion 132 in which a through hole 131 communicating with the shaft hole 111 is opened, that is, a portion of the bottom surface is engaged with the concave portion 112 to be inserted and detached ( 130a), and a hook unit 130b configured to protrude sideways from one side of the rotation unit 130a so as to detachably surround one side of the outer circumference of the second gas pipe GP2. The rotation unit 130a facing and in contact with the end face of the reference shaft 110 rotates around the shaft hole, and when the convex portion 132 is inserted into the concave portion 112 and engaged during rotation, the rotation unit 130a rotates. stop mechanically In this embodiment, the convex portion 132 also has a semicircular shape, and until the concave portion 112 and the convex portion 132 face each other, as shown in FIG. 6, the fixing hook 120 and the hook unit 130b do not overlap each other. Keep spaced up and down. Meanwhile, the hook unit 130b has a ring shape with one side open like the fixing hook 120, and one side of the outer circumference of the second gas pipe GP2 is press-fitted through the open side. In addition, an adhesive for close contact with the first gas pipe GP1 may be applied to the inside of the fixing hook 120 . Since the free hooks 130 and 130' must be configured to correspond to the fixing hooks 120 and 120', in response to the pair of fixing hooks 120 and 120' disposed at the top and bottom of the reference shaft 110 make a pair For reference, as shown in (c) of FIG. They are positioned so that they engage with each other when facing each other. That is, when the fixing hook 120 and the rotating hook 130 are inserted into the first gas pipe GP1 and the second gas pipe GP2, respectively, they maintain their respective states without mutual rotation even under external force.

The bolt 140 penetrates the through hole 131 and is screwed into the shaft hole 111 so that the free hook 130 can be moved up and down based on the cross section of the reference shaft 110. Since the shaft hole 111 is in the form of a female screw thread formed along the inner circumferential surface, the bolt 140 is drawn into the shaft hole 111 according to the direction of rotation. Therefore, when the bolt 140 is rotated in the pull-out direction of the hole 111, the free hook 130 moves up and down in a wider range along the bolt 140, and the bolt 140 moves in the pull-in direction of the hole 111. When rotated, the elevating range of the free hook 130 is reduced. Based on this structure, the operator rotates the bolt 140 in the withdrawal direction when installing the clamp, so that the fixing hook 120 and the rotating hook 130 in which the concave portion 112 and the convex portion 132 are not engaged with each other are formed on the second floor. To provide a free space to maintain the stacked state of. Thereafter, when the concave portion 112 and the convex portion 132 are engaged with each other, the operator rotates the bolt 140 in the pull-in direction so that the head 141 of the bolt 140 is attached to the free hook 130 so as to maintain the corresponding state. The rotation unit (130a) is pressed. Bolts 140 and 140' also form a pair to correspond to a pair of fixing hooks 120 and 120' and free hooks 130 and 130'.

The spring 150 applies a repulsive force to the extended head 141 of the bolt 140 and the prehook 130, respectively. In this embodiment, the spring 150 is in the form of a coil spring that wraps around the bolt 140, and both ends of the spring 150 come into contact with the head 141 and the free hook 130, respectively. Therefore, even when the concave portion 112 and the convex portion 132 are not engaged with each other, the rotation unit 130a of the free hook 130 maintains a state in close contact with the end face of the reference shaft 110 . In addition, when the concave portion 112 and the convex portion 132 face each other while the fixing hook 120 and the free hook 130 rotate with respect to the bolt 140, the convex portion 112 and the convex portion 132 face each other by the repulsive force of the spring 150. Portion 132 is inserted into and engaged with recessed portion 112 . As a result, the spring 150 immediately engages the concave portion 112 and the convex portion 132 without the hassle of aligning the positions of the concave portion 112 and the convex portion 132, so that the operator pulls in the bolt 140. You only need to continue the work of rotating in the direction.

In order to insert and fix the clamp 100 having the above structure into the first gas pipe GP1 and the second gas pipe GP2, the operator uses the fixing hook 120 and the free hook as shown in (a) of FIG. 130) is folded to each other to be inserted between the first gas pipe (GP1) and the second gas pipe (GP2), and as shown in (b) of FIG. 7, the open side of the fixing hook 120 and the free hook 130 After being fitted into the first gas pipe GP1 and the second gas pipe GP2, respectively, it is pushed between the first gas pipe GP1 and the second gas pipe GP2 while press-fitting.
