Step one, when the controller 56 receives a fire signal sent by the wireless terminal, the controller 56 lights the explosion-proof indicator lamp 57, the temperature sensor 55 detects the temperature of the door frame 31, if the temperature is higher than a set temperature, the explosion-proof indicator lamp 57 goes out, the position switch 54 continuously detects the position of the slider 52, after the door leaf 32 is closed, the position switch 54 detects the slider 52, the controller 56 sends a connection signal to the electric control lock 744, the electric control lock 744 drives the limit block 745 to move to the left side and relieve the limit of the limit slot 746, the fixture block 742 pushes the fixture block 742 to slide upwards under the elastic force of the spring 743 and clamp the clamp slot 72, and thus the slider 52 and the slide bar 63 are fixed;
step two, when the door leaf 32 is opened, the door leaf 32 pulls the sliding block 52 to move to the right side through the connecting rod 53, the sliding rod 63 fixedly connected with the sliding rod pushes the piston 62 to slide to the right side along the inner cavity of the hydraulic cylinder 61, the volume of the left side of the piston 62 is increased, the pressure is reduced to form negative pressure, under the action of pressure difference, the first one-way valve 643 on the left side is opened and spray liquid is extracted from the water tank 4 through the tee 642 and the water pumping pipe 641, the volume of the right side of the piston 62 is reduced, the pressure is increased, the spray liquid is pressed into the pressure cylinder 662 on the right side, the second one-way valve 651 on the right side is opened under the action of pressure difference, the spray liquid is continuously released through the spray assembly 65 under the action of subsequent air pressure, and the sprayed spray liquid can suppress the fire situation near the door frame 31;
step three, when the door leaf 32 is closed under the action of the door closer 34, the door leaf 32 pulls the sliding block 52 to move to the right side through the connecting rod 53, the sliding rod 63 fixedly connected with the sliding rod pulls the piston 62 to slide to the left side along the inner cavity of the hydraulic cylinder 61, the volume of the right side of the piston 62 is increased, the pressure is reduced to form negative pressure, under the action of the pressure difference, the first one-way valve 643 on the right side is opened, spray liquid is extracted from the water tank 4 through the tee 642 and the water pumping pipe 641, the volume of the left side of the piston 62 is reduced, the pressure is increased, the spray liquid is pressed into the pressure cylinder 662 on the left side, the second one-way valve 651 on the left side is opened under the action of the pressure difference, the spray liquid is continuously released through the spray assembly 65 under the action of the subsequent air pressure, and the sprayed spray liquid can suppress the fire near the door frame 31.
In conclusion, the fire alarm device can receive and feed back fire, can display the fire near the fireproof door through the explosion-proof indicator lamp, can continuously extract the spraying liquid from the water tank and release the spraying liquid in the opening and closing processes of the door leaf under the condition that the fire near the fireproof door occurs, has mechanical control in the whole process, and has extremely high reliability.
The above embodiments are merely illustrative of the technical concept and features of the present invention, and the present invention is not limited thereto, and those skilled in the art can understand the present invention and implement the present invention, and all equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention without departing from the spirit of the present invention.
