Description

Package Type Sprinkler Apparatus With A Hose Reel}

The present invention relates to a package-type hose reel sprinkler device, and more particularly, to a package-type hose reel sprinkler device that can be easily installed to be movable in an independent small building, and is capable of both automatic sprinkling by a sprinkler and manual sprinkling by a user. About.

In general, a simple sprinkler device is a firefighting facility that can be simply installed at a low cost in the same place as a multi-use facility of a small building, and the installation size or area is narrow to install a rated sprinkler device, and fire extinguishing equipment such as fire extinguishers. In order to provide a bay, it has characteristics that are mainly applied to places with high user density, and according to these characteristics, the frequency of application is increasing in recent years.

An example of such a simple sprinkler device may be a simple sprinkler facility (Registration Patent No. 10-1050827) shown at 101 in FIG. 1. This sprinkler facility 101 stores fire-fighting water in the water storage tank 105 through the water supply unit 103, as shown. In addition, the water storage tank 105 is connected to the sprinkler through the injection unit 107. Therefore, when the sprinkler is opened in the event of a fire, fire-fighting water in the fire-fighting water supply pipe 109 is injected in all directions through the sprinkler to extinguish the fire initially. Thereafter, when the pressure generating unit 111 detects a pressure drop in the injection unit 107, it pressurizes the water supply and the fire-fighting water in the reservoir 105 and discharges it to the injection unit 107, and is discharged to the injection unit 107 for firefighting. Water is sprayed to the point of fire through a sprinkler.

However, the conventional simple sprinkler device 101 as described above is only capable of automatic extinguishing by a sprinkler, and the user who finds the fire does not extinguish it directly, that is, before the sprinkler sprays fire-fighting water. There was a problem that could not be utilized.

In addition, if a direct fire extinguishing facility such as a fire hydrant is provided in addition to the sprinkler device 101 in order to extinguish a fire early, facility costs are incurred, the available space is reduced due to the above direct fire fighting facility, and maintenance becomes more complicated. There was this.

Accordingly, the automatic water supply pipe 13 detects a fire, and after the open sprinkler (S) primarily sprays the fire water on the sprinkling pipe (L), the fire water from the water supply source (9) is automatically supplied to the sprinkler (S). Supply.

In addition, the pressure gauge 15 is a means for detecting a pressure drop on the automatic water supply pipe 13, and is connected to and installed on the upper portion of the automatic water supply pipe 13, as shown in FIG. 2. Therefore, the pressure gauge 15 detects the pressure drop occurring on the automatic water supply pipe 13 after the sprinkler (S) is opened and the fire water in the sprinkling pipe (L) is primarily sprayed through the sprinkler (S). By doing so, the control unit can start the feed water pump 17.

Finally, the water supply pump 17 is a means for pumping fire fighting water from the water supply source 9 and supplying it to the sprinkler S when a fire occurs, as shown in Figs. 2 and 3, the water supply source 9 It is connected and installed between the and the automatic water supply pipe 13, that is, at the lower end of the automatic water supply pipe 13, for example. Therefore, as described above, when the pressure gauge 15 detects a pressure drop in the automatic water supply pipe 13, the water supply pump 17 is automatically started according to the command of the control unit, and automatically supplies the fire water of the water supply source 9 to the water supply pipe. Pump to (13). After the sprinkler (S) is opened so that the fire-fighting water on the sprinkling pipe (L) is sprinkled, the pumped fire water can continue to be sprayed through the sprinkler (S).

The manual sprinkling part 7 is a part in which the user can directly spray fire-fighting water at the point of fire, irrespective of the automatic sprinkling part 5, and as shown in FIGS. 2 and 3, automatic sprinkling It is installed at the front end of the case 3 so as to be adjacent to the part 5. Therefore, the manual spraying unit 7 sprays fire-fighting water supplied from the water supply source 9 through the fire hose H by the user's operation when a fire occurs, so that water can be manually sprayed.

To this end, the manual sprinkler 7 includes a hose reel 21 and a manual water supply pipe 23, and the hose reel 21 includes a fire hose H as shown in FIGS. 2 and 3. It is installed in the case 3 so that it can be wound and stored. Therefore, the hose reel 21 allows the user to manually spray the water for fire fighting by loosening the fire hose H when a fire occurs.

To this end, the hose reel 21 is a drum 31 on which a fire hose H is wound, as shown in FIGS. 2 and 3 and 4, and a fire hose H wound around the drum 31 is a drum. (31) A guide panel (33) to prevent separation to the outside, a reel water supply pipe (35) that supplies firefighting water to the fire hose (H) through the drum (31), and the reel water supply pipe (35) and the fire hose ( It comprises a connection pipe 37 connecting H).

Here, as shown in Fig. 4, the drum 31 has a curved end of the connection pipe 37 protruding from the circumferential surface around which the fire hose H is wound, and connects the water supply end of the fire hose H. It is supposed to be. In addition, the guide panel 33 is installed at both ends of the drum 31 and is formed in a donut shape along both ends of the drum 31. In addition, as shown in Figure 2, the reel water supply pipe 35 has one end connected to the manual water supply pipe 23, and the other end passes through the drum 31 and is connected to the connection pipe 37, thereby providing the manual water supply pipe 23. Connect with fire hose (H). Finally, the connection pipe 37 is a means for connecting the reel water supply pipe 35 to the rear end of the fire hose H wound around the drum 31, and further, the manual water supply pipe 23, as shown in FIG. Likewise, it is bent roundly along the circumferential direction of the drum 31 to increase the winding stability of the fire hose H.

On the other hand, the hose reel 21 is mounted on the wall of the water supply tank 9 in the case 3, for example, as shown in FIGS. 2 and 5, the link 39 pivotably coupled to the bracket 43 ) To the wall of the water supply tank (9) in the direction of the arrow (A), and through the hinge (41), the link (39) can be rotated in the direction of the arrow (B) centering on the tip of the link (39). . Therefore, when the hose reel 21 is in the position shown by the hidden line in FIG. 5, it is possible to more easily loosen the fire hose (H).

In addition, the manual water supply pipe 23 is a pipe connecting the water supply source 9 and the fire hose H so that water can be manually sprayed as above, for example, as shown in FIGS. 2 and 3, It is installed in the case 3 so as to be disposed between the hose reel 21 and the automatic water supply pipe 13, and is made of a bendable hose pipe or the like to allow the position change of the hose reel 21 as shown in FIG. 5. Therefore, in this case, the manual water supply pipe 23 sprays the fire water from the water supply source 9 to the fire occurrence point through the fire hose H when the on/off valve 51 is opened. However, as shown in Figs. 2 and 3, the manual water supply pipe 23 is connected between the pressure gauge 15 on the automatic water supply pipe 13 and the sprinkling pipe line L, to spray water through a fire hose (H). To do this, first unscrew the fire hose (H) from the hose reel (21), and then when the user opens the on/off valve (51), the water used in the automatic water supply pipe (13) is primarily directed to the outside through the fire hose (H). Water is sprayed, and the pressure gauge 15, which detects the pressure drop generated at this time, operates the water supply pump 17 as well to pass the fire hose H from the water supply source 9 through the automatic water supply pipe 13 and the manual water supply pipe 23. Firefighting water is sprayed through.

Meanwhile, the manual water supply pipe 23 may be connected between the water supply pump 17 and the pressure gauge 15 on the automatic water supply pipe 13 as shown in FIGS. 6 and 7 as another embodiment of the present invention. In this case, the user must open the on-off valve 51 and operate the feed water pump 17 at the same time. However, a check valve 53 is installed between the manual water supply pipe 23 and the pressure gauge 15 on the automatic water supply pipe 13, and for firefighting on the sprinkling pipe line (L) while water is sprayed through the manual water supply pipe (23). Water cannot flow back to the manual water supply pipe (23).

Now, the operation of the package type hose reel sprinkler device 1 according to a preferred embodiment of the present invention will be described as follows.

The sprinkler device 1 of the present invention is largely divided into the following two types and is selectively operated.Before a person discovers a fire, the sprinkler (S) may first detect the heat caused by the fire, and the sprinkler (S ), there are cases where a person finds the fire beforehand.

In the first case, when the sprinkler (S) is opened due to the heat of the flame, the water for firefighting on the sprinkling pipe (L) and the automatic water supply pipe (13) is instantaneously discharged through the sprinkler (S) and sprayed. Accordingly, a pressure drop occurs on the automatic water supply pipe 13, and the pressure gauge 15, which senses this, activates the water supply pump 17 through the control unit. The activated water supply pump 17 pumps the water for fire fighting from the water supply source 9 and supplies it to the automatic water supply pipe 13 and the sprinkling pipe line (L), and the supplied fire water continues to the point of fire through the sprinkler (S). So it is watered.

In the second case, before the sprinkler (S) is opened yet, that is, at the beginning of the fire when the heat of the flame is not yet relatively high, the user first discovers the fire, and the fire is extinguished through the manual sprinkler (7). .

To this end, in the first embodiment shown in FIG. 2, when a user who finds a fire unscrews the fire hose H from the hose reel 21 and opens the on/off valve 51, the automatic water supply pipe 13 is The filled fire hose (H) moves to the fire hose (H) through the manual water supply pipe (23) and sprays water. At this time, the pressure gauge (15) detects the pressure drop occurring in the automatic water supply pipe (13), and Similarly, the feed water pump 17 is started. The water supply pump 17 operated accordingly pumps fire water from the water supply source 9 and supplies it to the automatic water supply pipe 13 and the manual water supply pipe 23, and the supplied fire water is fired through a fire hose (H). It is continuously sprayed to the point of occurrence.

On the other hand, in the second embodiment shown in FIG. 6, when the user who finds a fire unscrews the fire hose H from the hose reel 21, opens the on/off valve 51 and operates the water supply pump 17, The fire water of the water supply source 9 pumped by the water supply pump 17 passes through the lower end of the automatic water supply pipe 13, the manual water supply pipe 23, and the hose reel 21 in order, and is targeted through the fire hose (H). Water is sprayed at the point of fire, and watering continues until the water supply pump 17 is stopped.
