The working principle is as follows:

firstly, in order to avoid the damage of the flame sensor 15 caused by the fire generated by the heat-insulating layer 4 directly, the fireproof plate 18 is arranged between the flame sensor 15 and the heat-insulating layer 4, the heat transfer is slow due to the small heat conductivity coefficient of the fireproof plate 18, the condition that the fire is transmitted from the fire at the heat-insulating layer 4 to the flame sensor 15 is avoided, meanwhile, the fire extinguishing mechanism can play a role in extinguishing the fire at the same time of the fireproof plate 18, and then the flame sensor 15 is well protected;

then, the flame sensor 15 utilizes the characteristic that infrared rays are very sensitive to flames, the flame sensor 15 detects flames through an internal specially-made infrared receiving tube, then the brightness of the flames is converted into electric signals with high and low changes, the converted electric signals are transmitted to the inside of the control circuit board 14 by the flame sensor 15, and corresponding program processing is carried out by the control circuit board 14 according to the changes of the electric signals, so that the flame sensor 15 is arranged, and the control circuit board 14 can conveniently extinguish the fire in the closed space 13;

then, when the flame sensor 15 senses that the flame brightness is generated in the closed space 13, an electric signal is transmitted to the control circuit board 14, and the control circuit board 14 opens the regulating valve 8 when receiving the electric signal, wherein the clean water pipe 5 guides water into the branch water pipe 12 for a long time, so that when the regulating valve 8 opens, the clean water at the branch water pipe 12 flows out to the water outlet 9 through the regulating valve 8, and sprays water into the closed space 13 through the water outlet 9 for fire extinguishing, wherein the control circuit board 14 adjusts the opening size of the regulating valve 8 according to the electric signal transmitted by the flame sensor 15, if the flame is brighter, the opening size of the regulating valve 8 is smaller, so that the water passes through the regulating valve 8 and becomes water pressure for fire extinguishing, conversely, the opening size of the regulating valve 8 is larger, so that the water passes through the regulating valve 8 and becomes water mist for fire extinguishing, when the flame sensor 15 does not sense the flame brightness, the control circuit board 14 closes the regulating valve 8 according to an electric signal transmitted by the flame sensor 15, and then the residual sewage in the closed space 13 is discharged to the sewage pipe 6 through the water outlet 11, so that the fire extinguishing mechanism can perform corresponding water spraying according to the flame (height) to extinguish fire, the fire extinguishing mechanism can better utilize water to extinguish fire, and meanwhile, the water is a common resource, thereby greatly reducing the cost of the whole device when in use;

subsequently, the anti-slip pads 502 are arranged on the two sides of the bottom end of the bottom plate 5, so that the bottom plate 5 can be kept stable when the anti-slip pads 502 are used, and meanwhile, the anti-slip pads 502 are meshed pads made of silica gel, so that the friction force of the bottom plate 5 contacting with a desktop through the anti-slip pads 502 is greatly increased due to the arrangement of the anti-slip pads 502, the anti-slip property of the bottom plate 5 is correspondingly greatly increased, and the situation that the bottom plate 5 slides when the smooth desktop contacts is avoided;

finally, when the user needs to splice the panels 2, the fixing pin 7 is screwed out counterclockwise to disconnect the panels 2 from the supporting post 6, then the movable plates 902 of the splicing plates 9 at the two sides of the back of the panels 2 are unfolded from the corresponding fixed plates 901 through the hinge posts, after the movable plates 902 and the fixed plates 901 are unfolded in a straight line shape, the movable plates 902 are attached to the splicing grooves 10 at the corresponding positions of the other panels 2, correspondingly, the movable plates 902 of the other panels 2 are rotated to the corresponding overlapping grooves 10 of the panels 2, then the bolts are screwed clockwise through the holes in the middle of the movable plates 902 and the corresponding grooves in the middle of the overlapping grooves 10, so that the panels 2 are fixedly connected with the other panels 2, and because the four splicing mechanisms are arranged at the connecting positions between the panels 2 and the other panels 2 for connection, therefore, when one splicing mechanism is unstable, other splicing mechanisms can continue to connect the panel 2 and the other panel 2, and the condition that one splicing mechanism is unstable to be fixed between the panel 2 and the other panel 2 to cause disconnection and falling is avoided, which is the working principle of the fire-proof device for the external thermal insulation material of the high-rise building curtain wall.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
