Description

  The present invention relates to a sprinkler control panel provided in a sprinkler fire extinguishing facility.

Buildings are obligated by the Fire Service Act to install disaster prevention equipment such as fire alarm equipment and fire extinguishing equipment depending on the purpose and size.
If the area of the building is small, there is no legal obligation to install disaster prevention equipment, but if the owner of the building wishes to install the disaster prevention equipment, it may be installed on its own.
Panels such as fire receivers and sprinkler control panels used in these disaster prevention facilities are equipped with a battery as a backup power source so that the functions of the facilities can be maintained for a predetermined time even if a power failure occurs. .

By the way, in recent years, because the frequency of fires at group home facilities has increased, the Fire Service Act has been revised, and for facilities targeting group homes, etc., it was previously installed only in facilities with a total area of 1,000 m ² or more. The installation of sprinkler fire extinguishing equipment, which had been required, has also become mandatory for target facilities with a total area of 275 m ² or more.
Because the total area is less than 1,000 m ² , it is a relatively small building, so it is possible to install a “specific facility water-linked sprinkler facility” that uses water in a facility of this size. ing.

As an example of such a sprinkler fire extinguishing facility using tap water (hereinafter, referred to as a water-coupled sprinkler facility), there is a residential sprinkler device disclosed in Patent Document 1, for example.
The sprinkler device for a house disclosed in Patent Document 1 is provided with a watering head that is opened by heat during a fire at a position facing the interior of the house, and the watering head is connected to the water supply pipe and pipe of the house. In the connected residential sprinkler device, a fire detection signal output from the sensor is provided between the water pipe and the pipe line while a sensor for detecting the occurrence of fire is disposed in the room. A leak detection mechanism for detecting damage to the conduit and the watering head, and the like, between the former valve and the conduit. A drainage mechanism for draining the water inside is provided (refer to the claims of Patent Document 1).

  In the residential sprinkler device disclosed in Patent Document 1, a sprinkler control panel is installed for controlling the opening and closing of the valve. However, since the sprinkler control panel is intended for a detached house, the sprinkler control panel is reduced in size and has a standby power supply. Since there is no space for storing the battery, and since the installation of a standby power source is not obligated by the Fire Service Act, a standby power source is not provided. Therefore, as a response to a power failure, a main valve (motor-operated valve) that opens automatically at the time of a power failure is used so that water can be discharged even during a power failure.

Japanese Patent No. 2517684

  However, as a countermeasure at the time of a power failure, the mechanism that opens the original valve as in Patent Document 1 has a problem that the wastewater treatment is required when the fire does not occur, and the mechanism becomes complicated.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide a sprinkler control panel that can operate reliably even during a power failure without having a complicated mechanism.

The inventor considered providing a spare power source in the sprinkler control panel.
A battery as a backup power source used in a fire receiver in a fire alarm facility installed in a conventional large facility has a rectangular parallelepiped shape with an axial cross section, and its thickness is the same as the thickness of the fire receiver body. It is almost equivalent. Therefore, when installing a battery as a backup power source in a conventional fire alarm system, install it at the bottom of the fire receiver's housing and place a printed circuit board or the like above it on the top side of the fire receiver. It was like that.
However, the case of the sprinkler control panel of the water-coupled sprinkler equipment is small because it is installed in a small-scale building such as a detached house, and a battery as a backup power source is installed in such a small case. In the case of arrangement, the conventional method cannot be housed in the housing, and the housing must be made large.
However, it is desirable to avoid increasing the size of the sprinkler control panel in consideration of the situation where the facility where the water-coupled sprinkler equipment is installed is small.
Thus, in order to install a battery as a backup power source in a sprinkler control panel of a specific facility water-coupled sprinkler facility, first, the arrangement becomes a problem.

Also, in facilities where water-linked sprinkler equipment is installed, the location where the sprinkler control panel is installed is also similar to that of large buildings where large-scale sprinkler fire extinguishing equipment is installed. It is not always possible to have a dedicated installation location, and therefore it can be installed in a location that is susceptible to external impacts. Therefore, it is also necessary to protect electronic components such as a printed circuit board that can be said to be the heart of the sprinkler control panel.
That is, as a function required for the sprinkler control panel of the water-coupled sprinkler facility, the sprinkler control panel can protect electronic components such as a printed circuit board against external impacts.

  The inventor has eagerly studied from the viewpoint of storing a battery as a backup power source and protecting electronic components such as a printed circuit board, and using a flat, substantially rectangular parallelepiped battery as a backup power source enables a storage in a small housing. At the same time, it was considered to give the battery a function as a protective member for the printed circuit board. The present invention is based on such knowledge, and specifically comprises the following configuration.

(1) A sprinkler control panel according to the present invention includes a housing composed of a main body and a lid, a printed circuit board installed in the main body and housed in the housing , and a printed circuit board installed so as to cover the printed circuit board A protective cover; a vertical wall provided on the bottom plate of the main body, the height of which is set higher than the height of the electrical component on the printed circuit board; and the vertical wall placed on the vertical wall and disposed above the printed circuit board protective cover And a flat, substantially rectangular parallelepiped battery that functions as a standby power source.

Preferably, the housing is formed of a main body and a lid that is attached to the main body and can be opened and closed, and the lid is fixed to the main body with a fixing screw in a closed state. In this case, it is preferable to provide a screw cover that hides the head of the fixing screw so that the head of the fixing screw cannot be seen from the outside. An example of providing this screw cover is as follows.
A recessed part is formed in the part where the fixing screw is installed, and the screw cover is inserted into the recessed part so that the surface of the screw cover and the surface of the lid body are flush with each other in the inserted state, that is, there is no step. To. As a method of fixing the screw cover, a through hole (opening) is provided on the lid side, a leg portion that can be inserted into the through hole is formed in the screw cover, and the leg portion is formed in the through hole. A locking portion that locks the edge of the through hole in the inserted state is provided.

  In the present invention, a housing for storing a printed circuit board, a printed circuit board protective cover installed so as to cover the printed circuit board, and a battery as a standby power source having a flat, substantially rectangular parallelepiped shape on the printed circuit board protective cover. By arranging it, the sprinkler control panel can be operated even in the event of a power failure, and the battery is arranged on the upper surface side of the printed circuit board protective cover that is arranged so as to cover the printed circuit board. At the same time, the battery has a function of protecting the printed circuit board.

The sprinkler control panel according to the present embodiment will be described with reference to FIGS. The sprinkler control panel 1 according to the present embodiment is a sprinkler control panel installed in a water-coupled sprinkler facility, and when a conshielded sprinkler head connected to a fire extinguishing pipe is activated by the heat of flame in the event of a fire. , Outputs an alarm sound, controls the opening of the valve, and, after the fire is extinguished, has a function to stop the water discharge by controlling the valve on the fire extinguishing pipe by operating the button on the panel ing.
The configuration of the sprinkler control panel 1 having the above functions will be described.

The sprinkler control panel 1 includes a box-shaped main body 3 and a housing 8 including a lid body 7 attached to the main body 3 by a hinge 5 so as to be opened and closed. A printed circuit board 9 is installed at the bottom of the main body 3 (see FIGS. 3 and 5), and serves as a printed circuit board protective cover for insulation so as to cover electrical components (not shown) mounted on the printed circuit board 9. A cover body 11 is installed (see FIGS. 3 to 5). The size of the printed circuit board 9 is substantially the same as the size of the bottom plate of the main body 3, and there is no storage space as a space for installing other members in the vertical direction and the horizontal direction of the printed circuit board 9. In addition, an outer line taking-in opening is provided on the upper side wall of the main body 3, and various signal lines are attached to the wiring connection portion at the upper part of the printed circuit board 9 through the opening.
A space 13 is formed above the cover body 11, that is, on the lid body 7 side (see FIG. 4), and this space 13 is a storage space for the battery 15 as a standby power source. In the space 13, a battery 15 as a backup power source having a flat and substantially rectangular parallelepiped shape is installed so as to cover the cover body 11. The dimensions of the battery 15 are, for example, about 140 mm in length, 95 mm in width, and about 15 mm in thickness. When the battery 15 is installed in the main body 3, as shown in FIG. Occupy an area of
The size of the battery 15 is as described above, but this size substantially corresponds to the size of the main body 3 (space 13). When the battery 15 is accommodated in the space 13, the battery 15 is laterally moved. Hardly moves. Regarding the depth direction, the size of the battery 15 is selected such that the position of the surface (upper surface) of the battery 15 is slightly smaller than the depth of the main body 3 when the battery 15 is housed. In other words, when the lid 7 is closed, the surface of the battery 15 and the back surface of the lid 7 are in a very close positional relationship. By using the battery 15 having such a size, even if an external force is applied to the lid 7, the force is dispersed on the surface of the battery 15, so that the lid 7 is not easily damaged or deformed.
Referring to the vertical direction of the battery 15, when the battery 15 is housed, the battery 15 covers the entire lower side of the printed circuit board 9, but the power switch at the upper left side of the printed circuit board 9 and the right side A part of the wiring connection portion at the top is exposed.

A claw portion 17 that holds the battery 15 is formed in the lower portion of the main body 3 (see FIGS. 1 and 4). The battery 15 is configured so that the upper surface sides of both lower corners are held by the claw portion 17. (See FIG. 1), and the connector 19 is connected to a terminal 21 in a wiring connection portion provided in the main body 3 (see FIGS. 4 and 7).
Further, the upper surface side of the battery 15 is held by a fixed belt 23 stretched in the width direction. As shown in FIG. 1, both ends of the fixing belt 23 are fixed to the main body 3 with screws 25. Thus, since the battery 15 is installed so as to cover the cover body 11, it also functions as a protective member for the cover body 11. Further, since the battery 15 is arranged in a state of being exposed when the lid body 7 is opened, it can be easily removed and replaced.
A vertical wall 3c is provided on the bottom plate of the main body 3 in the vertical direction. The vertical wall 3c is provided slightly on the left side from the center. A vertical wall 3d having the same height as the vertical wall 3c is also provided below the pair of claws 17 (see FIGS. 3 and 5). A battery 15 is placed on each end face of the vertical walls 3c and 3d.
Further, as described above, the height of the vertical walls 3c and 3d is adjusted so that the height of the main body 3 and the height of the upper surface of the battery 15 accommodated in the space 13 substantially coincide with each other. Further, the height of the vertical walls 3c and 3d is set to be higher than the height of the electrical components on the printed circuit board 9. For this reason, by placing the battery 15 on the vertical walls 3c and 3d, even if an external force is applied from the lid 7 side, the external force on the printed circuit board 9 is not applied.

  The lid body 7 is provided with a speaker 27 at an upper position in front of the lid body 7. Further, as shown in FIG. 2, various membrane switches 29 are provided below the speaker installation portion of the lid 7, and various operations can be performed. When the lid body 7 is closed, the lid body 7 is fixed to the screw holes 3e provided on the main body 3 side by fixing screws 31 provided at two positions on the upper and lower sides (see FIG. 6). In addition, as shown in FIG. 6, the part in which the fixing screw 31 is installed in the lid body 7 is a concave recess 33, and a screw cover 35 is attached so as to cover the recess 33 (FIG. 2).

The structure of the mounting portion of the screw cover 35 will be described in detail (see FIGS. 6 to 11).
First, the structure on the lid 7 side will be described. As shown in FIG. 6, a rectangular notch 34 is formed on the surface side of the lid 7 so as to be continuous with the recessed portion 33. The notch 34 is located at the edge of the lid 7, and the bottom of the notch 34 is an opening 34 a (through hole) that penetrates the back side of the lid 7.
Further, as shown in FIG. 8, a boss portion 43 into which the fixing screw 31 is screwed is provided on the back surface side of the lid body 7, and a boss portion 43 and a predetermined gap are provided on both sides of the boss portion 43. A locking piece 45 for locking the screw cover 35 is provided. Arc-shaped concave portions 47a and 47b are formed at two locations in the locking piece portion 45, a portion near the edge of the lid body 7 and a portion near the center. A recess 47a formed near the edge is for temporarily fixing the screw cover 35, and a recess 47b formed near the center is for stopping when the screw cover 35 is officially attached. It is. Each of the recesses 47a and 47b has a function of fixing the screw cover 35 by engaging a projection 41 formed on a leg portion of the screw cover 35 described later.
A guide piece 49 is provided in the gap between the boss portion 43 and the locking piece portion 45 to abut against the leg portion 39 (see FIG. 6) of the screw cover 35 to be inserted and to facilitate insertion. Yes.

Next, the structure of the screw cover 35 will be described (see FIGS. 6 and 9).
The screw cover 35 includes a head portion 37 that is inserted into the recessed portion 33 and covers the fixing screw 31, and a pair of leg portions 39 that are inserted into the opening portion 34 a of the notch portion 34, and the side surface shape is substantially V-shaped. (See FIG. 6). The distance between the pair of leg portions 39 corresponds to the width of the opening 34 a, and a protrusion 41 that engages with the concave portion 47 of the engagement piece portion 45 is provided on the outer surface of the distal end of the leg portion 39.

  When the screw cover 35 configured as described above is attached to the lid body 7, the screw cover 35 is arranged as shown in FIG. 6, and the leg portion 39 is laterally inserted into the notch portion 34 and the opening 34 a of the notch portion 34. And insert it all the way in. At this time, the protrusion 41 as the locking portion formed on the leg portion 39 of the screw cover 35 is locked to the recess 47b, and the screw cover 35 is fixed (see FIG. 10). In a state where the screw cover 35 is installed, the head 37 covers the fixing screw 31 and the surface of the screw cover 35 is flush with the surface of the lid 7 without any step.

When the screw cover 35 is removed from the lid 7, the lid 7 is mainly opened. In this case, the procedure is as follows.
As shown in FIG. 11, the screw cover 35 is pulled out so that the projection 41 of the leg portion 39 is engaged with the recess 47a on the edge side. In this state, the fixing screw 31 is not covered with the head portion 37 of the screw cover 35 and is exposed, so that the fixing screw 31 can be removed. The fixing screw 31 is removed, the lid body 7 is opened, and work such as replacement of the battery 15 is performed. When the work is completed, the lid 7 is attached again, the fixing screw 31 is screwed in, and then the screw cover 35 in the temporarily fixed state is pushed into the state shown in FIG.
As described above, since the screw cover 35 can be temporarily fixed, the work can be performed without removing the screw cover 35 when the lid 7 is opened when the battery 15 is replaced. Excellent workability.

In the sprinkler control panel 1 of the present embodiment configured as described above, a flat, substantially rectangular parallelepiped battery 15 is placed over the cover body 11 of the printed circuit board 9 so as to cover the cover body 11. Therefore, it is very easy to attach, remove and replace when the lid 7 is opened. In the replacement, the screw 25 on one side of the fixing belt 23 may be removed and removed.
Moreover, since the battery 15 of the present embodiment is a flat, substantially rectangular parallelepiped shape, it can be stored in the thin casing 8. Further, since the flat, substantially rectangular parallelepiped battery 15 is installed so as to cover the cover body 11, it also functions as a protection member for the printed circuit board 9 installed below the cover body 11.
