Referring to FIGS. 1 to 7, a performance site fire fighting apparatus 100 according to an embodiment of the present invention includes a fire fighting film 110, a driving unit 120, a braking unit 130, and an operating unit 140.

The fire retardant film 110 is installed on the upper part of the stage and is lowered to the front side of the stage by the driving part 120. The refractory limit of the fireproof film 110 must meet both the international current standard (DIN) and domestic local fire protection standards.

The fire protection film 110 according to the present embodiment is made of a fire retardant, so that the weight used can be significantly reduced.

2, the driving unit 120 includes a driving motor 122, a drum 124 rotated by the driving motor 122, and a driving motor 122. The driving unit 120 includes a driving motor 122, And a driving wire 126 which is wound on the insulating film 124 and connected to the fireproof film 110.

The driving force of the driving motor 122 is transmitted by the helical gear or the bevel gear to rotate the drum 124 and the driving wire 126 wound on the drum 124 is loosened or wound, . The driving wire 126 is changed in the traveling direction by the pulley 127 to move up and down the fireproof film 110.

The braking unit 130 stops the operation of the driving unit 120. [ The braking unit 130 includes a disc brake for stopping the rotation of the driving unit 120 and stopping the falling of the fireproof film 110.

The operation unit 140 selectively releases the braking of the braking unit 130 to cause the fireproof film 110 to fall freely. The operation unit 140 includes a manual operation unit 142, a brake lever 145 provided in the braking unit 130, and an interlocking mechanism 145 that is mechanically connected to transmit the operation of the manual operation unit 142 to the operation of the brake lever 145. [ (150).

The operation unit 140 according to the present embodiment can perform a function even in an emergency state such as a power failure due to a mechanical connection relationship.

The manual operation panel 142 includes an operation lever 143 rotatably provided on the wall and a ring member 144 hooked on the operation lever 143. That is, the coupling of the ring member 144 can be disengaged by the rotation of the operation lever 143, and thereby the brake lever 145 can be operated by the interlocking portion 150.

The interlocking portion 150 is provided on the operation wire 152 extending from the manual operation panel 142 and the link bracket 154 and the operation wire 152 interconnecting the operation wire 152 and the brake lever 145 And a load member 156 for actuating the brake lever 145 by changing the tension of the operating wire 152 by the operation of the manual operating member 142. [

3, the link bracket 154 is refracted and the central portion thereof is hinged, and the operation wire 152 is moved in the direction of the driving unit 120 by the refraction pulley 153, The other end of the link bracket 154 is connected to the brake lever 145 and the other end of the link bracket 154 is connected to the other end of the link bracket 154 with the load member 156 as a free end And is connected to the operating wire 152. Therefore, when the tension of the operation wire 152 is maintained, the brake lever 145 is not operated, and when the tension of the operation wire 152 is released, the load of the load member 156 causes the brake lever 145 And is actuated by the link bracket 154.

 At this time, a plurality of manual operation panels 142 may be provided on the stage. That is, since the manual operation panel 142 is provided on both sides of the stage, the fire-fighting membrane 110 can be operated immediately. In this embodiment, the manual operation panels 142 are shown on both sides of the stage, but the present invention is not limited thereto and may be provided in various places.

Since the manual operation panel 142 is provided on both sides of the manual operation panel 142 as well as the manual operation panel 142 of the other side, the operation wire 152 is extended to the driving part 120 side by the refraction pulley 153 and connected to the load member 156. That is, the manual operation boards 142 on both sides are connected to each other by connecting the operation wires 152 to one load member 156 side.

The operation unit 140 includes a buffer 160 for buffering a mechanical shock caused by the free fall of the fire retardant film 110. The buffering part 160 is connected to the hydraulic pump 162 and the hydraulic pump 162 provided with the rotary rotary 163 connected to the rotary shaft of the driving part 120 and the circulating pipe 165, And a control valve 166 for controlling the flow rate of the hydraulic oil circulated in the hydraulic tank 164 and the hydraulic pump 162.

When the braking operation of the brake lever 145 is released by the operation of the brake lever 145, the free fall falls due to the load of the fire retardant film 110. By reducing the rotational speed of the rotary shaft by applying a load to the rotary shaft, It is to buffer the shock. The load is applied to the rotary rotary 163 by the flow of the hydraulic fluid circulated in more detail, and the number of revolutions of the rotary shaft can be reduced.

Then, the freely falling fireproof film 110 is dropped by the slide portion 170 in a straight line. The slide unit 170 is guided to a straight line when the load cell is lifted and lowered by the drive unit 120 and is connected to the guide rail bracket 172 and the guide rail bracket 172 provided on both sides of the stage, And guide blocks 174 formed on both sides thereof. The guide rail brackets 172 are bolted to both side walls of the stage and guide rails are formed on the opposite surfaces of the guide rail brackets 172 to be coupled with the guide blocks 174. [

The operation unit 140 further includes an emergency switch unit 180 for changing the tension of the operation wire 152 by an external signal. The emergency switch portion 180 includes a roller portion 182 for forming an extra portion on the path of the operation wire 152 and a spare portion of the inter-operation wire 152 by operating the roller portion 182 by an external signal And an operation switch 185 for changing the tension of the operation wire 152.

The roller unit 182 includes a fixed roller 183 and a moving roller 184 which are spaced apart from each other by a predetermined distance and the operation switch 185 is formed of a magnetic force member for selectively fixing the moving roller 184. That is, depending on whether or not the power source is supplied by the external signal, the operation switch 185 is moved away from the magnetic force, and the moving roller 184 is moved to include the spare portion of the operation wire 152. The moving roller 184 can be moved horizontally by the guide guide 186. [ Here, the magnetic force member, which is the operation switch 185, may be composed of an electromagnet generating a magnetic force when power is supplied, or an electromotive magnet losing a magnetic force supplied with power.

At this time, the operation switch 185 is provided with an emergency power supply 187 capable of supplying the emergency power.

The operation wire 152 is provided with a safety member 190 for cutting the operation wire 152 by temperature. The safety member 190 connects between the operation wires 152 and melts at a predetermined temperature when the fire is generated to cut the operation wire 152 to allow the fireproof film 110 to fall freely. Such a safety member is formed of a link fuse, and a plurality of operation wires 152 may be provided.

On the other hand, the end portion of the fire shielding film 110 is provided with a fire fighting pad 115 for cushioning mechanical impact and hermetically sealing the inside and outside of the fire shielding film 110.

Hereinafter, the operation and effect of the artificial conflagration membrane device according to one embodiment of the present invention will be described.

When a fire occurs on the stage, a person who finds the first fire operates the manual operation panel 142 to freely drop the fireproof film 110 to the front of the stage.

The operation of the brake lever 145 can be operated by the mechanical operation of the interlocking part 150 at the same time as the operation lever 143 is rotated. That is, due to the mechanical connection, it is possible to perform the function even in an emergency state such as a power failure, thereby ensuring reliability.

2 and 3, when the operation lever 143 is rotated upward, the binding with the loop member 144 is released, and the tension of the operation wire 152 is released. Then, the brake lever 145 of the braking member 130 is actuated by the load of the load member 156.

When the braking of the braking unit 130 is released by the operation of the brake lever 145, the fireproof film 110 falls freely by the load of the fireproof film 110. At this time, the free fall of the fire retardant film 110 can be buffered by the buffer 160. That is, as shown in FIG. 4, hydraulic oil is introduced into the hydraulic pump 162 connected to the rotating shaft of the driving unit 120 to give a load, thereby reducing the rotating speed of the rotating shaft. As a result, the free fall of the fire retardant film 110 can be buffered, and the fire retardant film 110 can be prevented from being damaged.

The free fall of the fireproof film 110 can be dropped by the slide portion 170 in a straight line, and can be dropped to the correct position.

As shown in FIGS. 1 and 7, the manual operation panels 142 are provided on both sides of the stage, respectively, to enable immediate operation of the fire-fighting membrane 110 in the event of a fire.

Even in the absence of the operator, emergency operation can be performed by the emergency switch unit 180. [ As shown in FIGS. 5 and 6, when a fire detection signal is applied in the disaster prevention room in a state where a spare portion of the operation wire 152 is formed by the fixing roller 183 and the moving roller 184 which are spaced apart from each other by a predetermined distance The tension of the operation wire 152 is released while the movement roller 184 fixed by the operation switch 185 is moved. By this operation, the fire retardant film 110 can be operated even in the absence of the operator.

Further, the operation wire 152 of the present embodiment is provided with the safety member 190, which doubles the safety. That is, in the event of fire, the operation wire 152 is broken by a heat source, and the fireproof film 110 can be freely dropped automatically, thereby ensuring safety.

In addition, the fire protection film 115 is provided at the end of the fire protection film 110 to buffer the mechanical impact and improve airtightness, thereby preventing the smoke from moving in the auditorium or the stage direction during a fire.

As described above, according to the artificial fireplace membrane device according to the embodiment of the present invention, when a fire or an emergency occurs, the passenger compartment and the stage are blocked by the fireproof film, The free fall can be buffered by the cushioning portion during the free fall of the fireproof film to prevent the breakage of the fireproof film and to prevent the loss of function due to the breakage and to operate the fireproof film by the application of the emergency signal The emergency switch unit can be operated even in the absence of the operator, thereby improving the stability.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand.

Accordingly, the true scope of protection of the present invention should be defined by the claims.
