BEST MODE FOR CARRYING OUT THE INVENTION A preferred embodiment of an inspection system and an inspection method for a fire protection switchgear device according to the present invention will be described below with reference to the accompanying drawings. In this embodiment, a fire shutter device having a shutter curtain that is opened and closed vertically will be described as an example of the opening and closing means, which is a shielding member. FIG. 1 is a diagram showing a schematic configuration of a fire shutter device, which is a fire protection opening/closing device according to one embodiment of the present invention. In FIG. 1, a fire prevention opening/closing device 10 is a fire prevention shutter device that vertically opens and closes a shutter curtain 12 as a shielding member.

The fire prevention opening/closing device 10 is provided in an internal space or an opening of a structure such as a building, and basically includes a shutter case 11, a shutter curtain 12, guide rails 13 and 14, a winding shaft 15, a chain 16, It includes a motor 17, a brake 18, an interlock relay 19, an automatic closing device 20, a limit switch 21, a connection box 22, and the like.

The guide rails 13, 14 are provided at both ends of the internal space or opening of the building so as to contact both ends of the shutter curtain 12, and have a U-shaped cross-section spanning from the lintel to the floor surface. It is composed of a metal member having a guide groove or an equivalent member. The shutter curtain 12 moves up and down along the guide grooves of the guide rails 13 and 14 to open and close.

The winding shaft 15 is rotatably provided on both end sides of the shutter case 11 to wind up and rewind the shutter curtain 12 . The chain 16 connects a driving sprocket provided on the rotation shaft of the motor 17 and a driven sprocket provided on the rotation shaft of the winding shaft 15 . Therefore, the rotational driving force of the motor 17 is transmitted to the winding shaft 15 side via the chain 16, and when the motor 17 rotates, the winding shaft 15 rotates via the chain 16, and the shutter curtain 12 is opened and closed. It is supposed to be controlled.

Normally, the fire prevention opening/closing device 10 mechanically maintains the open state in which the shutter curtain 12 is wound around the winding shaft 15 by means of the brake 18 . Then, when an emergency signal BS indicating the occurrence of a fire or the like is input to the interlocking relay 19 from the outside, the interlocking relay 19 outputs a closing instruction signal to the automatic closing device 20, and the automatic closing device 20 closes. The brake 18 is opened according to the instruction signal, and the hold of the open state of the shutter curtain 12 by the brake 18 is released. When the hold of the open state by the brake 18 is released, the shutter curtain 12 naturally descends under its own weight to automatically close a part of the internal space or the opening of the structure such as a building.

The emergency signal BS is a DC voltage signal of 24 [V] supplied from an external control room or the like in an emergency such as a fire, and is input to the interlock relay 19 for harm prevention. The interlock repeater 19 is supplied with AC power of, for example, 100 V from the power line AC of the commercial power supply, and also receives an operation signal and a recovery signal from the connection box 22 described later.

The actuation button 23 is, for example, a push button switch, and an actuation signal is output from the connection box 22 to the interlock relay 19 by operating the actuation button 23 . The interlocking relay 19 outputs a closing instruction signal to the automatic closing device 20 when an operation signal is input from the connection box 22 . The closing instruction signal is a signal with a DC voltage of 24 [V], and the automatic closing device 20 opens the brake 18 while the closing instruction signal is being input from the interlock relay 19, and the shutter curtain 12 is closed by the brake 18. Release the hold of the open state.
By operating the operation button 23 provided on the connection box 22, an instruction for closing the shutter curtain 12 by the automatic closing device 20 is easily performed.

The restore button 24 is, for example, a push button switch, and a restore signal is output from the connection box 22 to the interlocking repeater 19 by operating the restore button 24 . When the restoration signal is input from the connection box 22 , the interlocking relay 19 stops outputting the closing instruction signal to the automatic closing device 20 . When the closing instruction signal is no longer input from the interlock relay 19 , the automatic closing device 20 operates the brake 18 to restore the open state of the shutter curtain 12 by the brake 18 .
By operating the restore button 24 provided on the connection box 22, an instruction to restore the open state of the shutter curtain 12 by the brake 18 is easily performed.
