Description

Fire Hydrant Stand for Construction {Fire Hydrant Stand for Construction}

The present invention relates to a fire hydrant stand for a building fire-fighting facility, and more specifically, to a fire hydrant stand for a building fire-fighting facility that can safely protect a water supply pipe installed inside the fire hydrant stand from external impact.

As is well known, a fire hydrant is a firefighting facility installed in a water supply pipe to install a fire hose, and an indoor fire hydrant for building use is installed in a stand together with a transmitter and a pilot light.

Typically, fire hydrant stands are installed indoors or in underground parking lots of buildings, commercial facilities, or apartments.

Recently, there have been frequent incidents of fire hydrant stands installed in underground parking lots being damaged by collisions with moving vehicles, as shown in Fig. 5, resulting in the stand (1) and door (2) being damaged. The main damaged area of the fire hydrant stand is the door (2) located at the front of the stand (1).

And, inside the fire hydrant stand, a water supply pipe (10) is provided to connect a fire hose (20). However, since the conventional fire hydrant stand is manufactured in the shape of a body by processing a thin metal plate, there was a problem in that the internal equipment could not be safely protected from collision with a vehicle.

In particular, if the water supply pipe (10) and the valve (11) controlling the water supply inside the fire extinguisher stand are damaged due to a vehicle collision, it may lead to significant damage due to water leakage, so a technology for preventing damage to the water supply pipe (10) and valve (11) is required.

(0001) Republic of Korea Publication Patent No. 10-2009-0009695 (Publication date: January 23, 2009)

The present invention has been made to solve the conventional problems as described above, and an object of the present invention is to provide a fire hydrant stand for building firefighting facilities that can safely protect a water supply pipe installed inside the fire hydrant stand from external impacts such as from vehicles.

In order to achieve the above object, the present invention provides a fire hydrant holder for building firefighting facilities, comprising a holder having a rear panel to accommodate a water pipe and a fire hose, and a door connected to open and close the open front of the holder, the technical idea including: a detection module that detects a vehicle approaching the fire hydrant holder, determines a collision in advance, and outputs an operation signal; an upper airbag module installed on the rear panel of the holder and inflates obliquely toward the upper inner surface of the door in response to the operation signal of the detection module to protect the water pipe; a lower airbag module installed on the rear panel of the holder to form a storage space under the upper airbag module and inflates obliquely toward the lower inner surface of the door in response to the operation signal of the detection module to protect the water pipe; and a center guard member that is stored in the storage space while unfolding toward the center of the inner surface of the door when the upper airbag module and the lower airbag module are inflated and protects against impact.

The upper airbag module may include an upper case detachably installed on the rear panel of the mounting box, an upper igniter built into the upper case and igniting according to an operating signal input from the detection module, an upper inflator built into the upper case to generate nitrogen gas by ignition of the upper igniter, an upper airbag that expands obliquely toward the upper inner surface of the door by the nitrogen gas generated from the upper inflator, and an upper cover coupled to a tip of the upper airbag and opening and closing the open front surface of the upper case.

The above lower airbag module may include a lower case detachably installed on the rear panel of the above mounting box, a lower igniter built into the lower case and igniting according to an operating signal input from the detection module, a lower inflator built into the lower case to generate nitrogen gas by ignition of the lower igniter, a lower airbag that is obliquely expanded toward the lower inner surface of the door by the nitrogen gas generated from the lower inflator, and a lower cover connected to a front end of the lower airbag and opening and closing the open front surface of the lower case.

The above center guard member may include a center airbag that is stored in the storage space to connect the upper cover and the lower cover and that is expanded to widely protect the inner surface of the door when the upper airbag and the lower airbag inflate, and a center cover that is separated between the upper cover and the lower cover when the center airbag is expanded.

According to the present invention implemented by the above-described solution means, if a collision of a vehicle approaching a fire hydrant stand is determined in advance by a detection module, the upper airbag and the lower airbag are inflated obliquely toward the upper and lower inner surfaces of the door, respectively, to primarily alleviate the upper and lower water pipes from the impact of the vehicle, and at the same time, the center airbag is inflated toward the center of the inner surface of the door, to secondarily alleviate the upper and lower water pipes from the impact of the vehicle through the overlapping of the upper and lower airbags, so that the water pipes installed inside the fire hydrant stand can be safely protected from the external impact of the vehicle, thereby having a very useful effect.

In addition, according to the present invention implemented with the above-described solution, the upper airbag and the lower airbag, which operate to expand obliquely, are controlled so that they do not expand beyond the range of expansion by the upper stopper and the lower stopper, so that the stability of operation together with the center airbag can be improved, which is a very useful effect.

In addition, according to the present invention implemented with the above-described solution, the upper airbag module, the lower airbag module, and the center guard member form a single assembly structure, so that after one use, the product can be separated from the rear panel of the fixed-type mounting box and a new product can be reinstalled, so there is a very useful effect of reducing costs in terms of economy.

A lower bracket (511) is provided at the bottom of the lower case (510), and this lower bracket (511) is detachably installed on the rear panel (110) by screw connection.

The lower igniter (520) applies current to the ignition circuit to generate a spark according to the operating signal of the detection module (300) that determines a collision of a vehicle approaching the fire extinguisher stand.

The lower inflator (530) combusts a gas generator by a flame generated from the lower igniter (520) and supplies the generated nitrogen gas to the interior of the lower airbag (540).

The lower airbag (540) is inflated by nitrogen gas supplied from the lower inflator (530) and wraps around the front of the water supply pipe (10) installed at the bottom of the fire extinguishing chamber (100b) as shown in Fig. 4, thereby primarily alleviating the impact of a vehicle colliding with the door (200). The upper part of the front end of the lower airbag (540) is connected to the upper end of the center airbag (610) described later so as to be continuous, thereby supplying the nitrogen gas supplied from the lower inflator (530) to the center airbag (610).

The lower cover (550) is separated from the lower case (510) when the lower airbag (540) expands and is directed toward the lower inner surface of the door (200). The upper portion of the lower cover (550) is provided with a lower extension (551) that protrudes upward from the lower case (510) and is integrally formed to fix the lower portion of the center airbag (610). The lower cover (550) may be provided with a lower cushioning shoe (560) made of a synthetic resin material including silicone, sponge, etc. to have elasticity and cushioning functions. The lower cushioning shoe (560) functions to cushion the impact generated when the lower airbag (540) expands and collides with the lower stopper (220).

Referring to FIG. 1, the center guard member (600) is stored in a storage space formed between the upper airbag module (400) and the lower airbag module (500).

The center guard member (600) is stored in a storage space to connect the upper cover (450) and the lower cover (550), and includes a center airbag (610) that is expanded to widely protect the inner surface of the door (200) when the upper airbag (440) and the lower airbag (540) are inflated, and a center cover (620) that is separated between the upper cover (450) and the lower cover (550) when the center airbag (610) is expanded.

The upper part of the center airbag (610) is connected to the lower part of the front end of the upper airbag (440) so as to be connected in communication with it, and the lower part is connected to the upper part of the front end of the lower airbag (540) so as to be connected in communication with it, and is inflated by nitrogen gas supplied from the upper inflator (430) and the lower inflator (530). In addition, the upper part of the center airbag (610) is fixed to the upper extension (451) extended from the upper cover (450), and the lower part is fixed to the lower extension (551) extended from the lower cover (550). When the center airbag (610) is inflated to the center of the inner surface of the door (200), it overlaps the upper airbag (440) and the lower airbag (540) as illustrated in FIG. 4, and thus the upper and lower water supply pipes (10) can be secondarily alleviated from the impact of the vehicle.

The center cover (620) is made of a film material so that it can be easily separated when the center airbag (610) is deployed by connecting the upper extension (451) extended from the upper cover (450) and the lower extension (551) extended from the lower cover (550). The center cover (620) can be made of the same color as the holder (100) and the upper airbag module (400) and the lower airbag module (500) to provide a neat appearance by covering the center airbag (610) covered in the storage space.

The operation of the embodiment of the present invention configured as described above is described in detail with reference to the attached drawings as follows.

First, when a vehicle approaches the perimeter of the fire extinguisher stand, the detection module (300) detects the proximity of the vehicle and, based on this, determines in advance that the vehicle will collide, and outputs an operation signal to the upper airbag module (400) and the lower airbag module (500).

According to the operating signal of the detection module (300), the upper airbag (440) of the upper airbag module (400) expands obliquely toward the upper inner surface of the door (200), and the lower airbag (540) of the lower airbag module (500) expands obliquely toward the lower inner surface of the door (200).

Next, the upper airbag (440) is guided by the upper stopper (210) and the expansion top point is blocked and the movement is prevented. At this time, the upper airbag (440) wraps around the front of the water supply pipe (10) installed on the upper part of the fire extinguishing chamber (100b) as shown in Fig. 4 to alleviate the impact caused by a vehicle collision.

At the same time, the lower airbag (540) is guided by the lower stopper (220) and the expansion of the lower dead point is blocked and the movement is prevented. At this time, the lower airbag (540) wraps around the front of the water supply pipe (10) installed at the bottom of the fire extinguishing chamber (100b) as shown in Fig. 4 to alleviate the impact caused by a vehicle collision.

In addition, the center airbag (610) is inflated by nitrogen gas supplied from the upper inflator (430) and the lower inflator (530) to widely protect the central portion of the door (200) as shown in FIG. 4.

Therefore, according to the embodiment of the present invention described above, if the collision of a vehicle approaching the fire hydrant stand is determined in advance by the detection module (300), the upper airbag (440) and the lower airbag (540) are each inflated obliquely toward the upper and lower parts of the inner surface of the door (200) to primarily alleviate the upper and lower water supply pipes (10) from the impact of the vehicle, and at the same time, the center airbag (610) is inflated toward the center of the inner surface of the door (200) to secondarily alleviate the upper and lower water supply pipes (10) from the impact of the vehicle through the overlapping of the upper airbag (440) and the lower airbag (540), so that the water supply pipe (10) installed inside the fire hydrant stand can be safely protected from the external impact of the vehicle.

In addition, according to the embodiment of the present invention described above, the upper airbag (440) and the lower airbag (540) that operate to expand in an inclined manner are controlled so that they do not expand beyond the range of expansion by the upper stopper (210) and the lower stopper (220), so that there is an advantage in that the stability of operation can be improved together with the center airbag (610).

In addition, according to the embodiment of the present invention described above, the upper airbag module (400), the lower airbag module (500), and the center guard member (600) form a single assembly structure, so that after one use, the product can be separated from the rear panel (110) of the fixed-type stand (100) and reinstalled as a new product, so there is an advantage in that costs can be reduced in economic terms.

The embodiments of the present invention described above are merely exemplary, and those skilled in the art to which the present invention pertains will readily appreciate that various modifications and equivalent other embodiments are possible.

Therefore, it can be well understood that the present invention is not limited to the forms mentioned in the detailed description above.

Accordingly, the true technical protection scope of the present invention should be defined by the technical idea of the appended claims, and the present invention should be understood to include the technical idea defined by the appended claims and all modifications, equivalents, and substitutes within the scope thereof.
