Description

[Detailed description of the invention] [Industrial application field] This invention involves opening the door to pull out the hose that is wrapped around a hose reel and housed in the hose storage chamber, and then opening the operation door to release the extinguishing liquid. In a fire extinguishing system configured to operate the operating lever of a discharge valve, this is related to an operation-related information display device, and the operation-related precautions appear close to the operator as the door opens. It has been devised to ensure accurate operation.

[Conventional technology]

Conventionally, such operation-related precautions were simply displayed on the back or front of the operation door, and in the event of an emergency operation, it was difficult to attract the attention of a hasty operator, and it was difficult to avoid incorrect operation. There is a big concern that it will be difficult to perform the operation, or that the operation will be time-consuming.

For example, in car tunnels, etc., fires are caused by the combustion of gasoline, so quick operations are especially important, and even for drivers who are not familiar with extinguishing fires, operation-related The precautions must be designed so that they can be easily read.

[Problem that the invention attempts to solve]

This invention was devised to prevent the operator from making operational errors and to enable quick operation.

[Means for solving problems]

In order to solve the above problems, this invention takes the following technical measures.

That is, the hose storage chamber 14 that houses the hose reel 7 and the hose 8 with the nozzle 36 wound thereon is closed by the main door 5, and the extinguishing liquid discharge valve 15 connected to the hose 8 is operated. Lever 1
In a fire extinguishing system equipped with an operation door 18 that must be opened to operate the main door 5, the opening operation related precautions 22 can be quickly triggered independently of the main door 5 by opening the main door 5. The operating door 18 displays on its back surface a cautionary note 22 related to the operation of the operating lever 16, and a spring body 23 that is always biased in the opening direction and the main door. 5 is provided with a locking portion 18a that locks with the main door 5 when the door 5 is closed.

[Example and operation]

In the following embodiment of this invention, a hose reel around which a hose is wound is pivotally supported on the back of the door, and the door is freely pulled out from the equipment frame, and the door is pulled out between the door and the equipment frame. An example will be described in which the present invention is applied to a fire extinguishing system configured to draw out a hose from a gap created by the fire extinguisher.

It has an extremely simple structure consisting of only a few simple parts.

Further, a lighting lamp capable of illuminating the operation-related precautions 22 is provided near the operation-related precautions 22, and the lighting lamp lights up in conjunction with the opening operation of the door 5 or the operation door 18 to draw the operator's attention. The user may be directed to the operation-related precautions 22 more strongly, or at the same time, a buzzer may be sounded or an audio display may be provided.

Further, the operation-related precautions 22 may be displayed using electrical characters such as a neon bulb or a liquid crystal display.

Next, to explain the moving mechanism 6 of the illustrated example, guide rails 25, 25, 25, 25 are provided on the front and rear of the left and right side columns 24, 24 of the device frame 4, and the hose reel 7 is pivotally supported. Roller mounting beams 28, 28 are attached to the left and right side pillars 27, 27 of the reel support frame 26.
The roller mounting beam 28 is sandwiched from above and below by the rollers 29, 29 provided near the end of each guide rail 25 near the door 5, and the roller mounting beam 28 is placed near the end of each guide rail 25 near the main door 5. The rollers 30, 30 provided near the ends can roll on the upper and lower guide rails 25, 25 with little play, and a stopper 31 is provided on the guide rail 25, and The distance between the storage position where the door 5 is substantially flush with the front plate 20 of the equipment box 3 that is stretched, and the use position where the roller 30 collides with the stopper 31 when the reel support frame 26 is pulled out. The main door 5 is movable.

In addition to the above-mentioned moving mechanism 6, various other mechanisms can be used, such as a structure in which a roller is provided above the main door 5 and the main door 5 is suspended.

Moreover, the shaft support structure of the illustrated hose reel 7 is based on the journal hole 9b of the hollow cylindrical joint body 9.
, the journal boss portion 1 of the hollow cylindrical rotating body 10
0b is fitted in a water seal shape so as to be rotatable about the rotational axis C, and one side plate 7a of the hose reel 7 is attached to the mounting seat 10c of the rotating body 10 with bolts 32, 32...
The mounting beam 3 is fixed at the rear end of the roller mounting beams 28, 28 of the reel support frame 26.
