Description

Technical Field

[0001] The invention belongs to the technical field of fire doors, and in particular relates to a highly flame-retardant steel fire door with ventilation function. Background Art

[0002] A steel fire door refers to a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with a certain fire resistance installed between fire compartments, evacuation stairwells and vertical shafts. Most of the existing fire doors have good airtightness and do not have ventilation function, and cannot ensure the ventilation of fire passages in daily use. Moreover, some fire doors with ventilation holes mostly need to be opened or closed manually. However, when a fire occurs, people cannot close the ventilation holes in time and effectively. Thick smoke and other toxic gases enter the fire passages through the ventilation holes, causing secondary injuries to the escapees in the fire passages, adding certain safety hazards. No dust removal device is installed at the ventilation openings, and the ventilation openings are usually fixed and welded on the door panels, resulting in the air outlets being blocked by dust after a period of time, poor ventilation effect, and difficulty in cleaning. Summary of the invention

[0003] The purpose of the present invention is to provide a highly flame-retardant steel fire door with ventilation function. The smoke sensor transmits an alarm signal to the controller, so that the control box can control the telescopic movement of the electric telescopic rod, driving the smoke baffle to block the vent. At this time, the socket is inserted into the plug, and the bidirectional motor is energized to drive the annular brush plate to rotate and clean the dust on the surface of the ventilation plate; when the alarm is lifted, the smoke sensor transmits a non-alarm signal to the controller, controlling the electric telescopic rod to pull the smoke baffle away from the vent, thereby solving the existing problem.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0005] The present invention is a highly flame-retardant steel fireproof door with ventilation function, comprising a door panel, a smoke sensor, a control box, a controller and an electric baffle; the electric baffle is slidably matched with the inside of the door panel; an installation cavity is opened inside the door panel; ventilation holes are symmetrically opened on both sides of the inner wall of the installation cavity; a plurality of threaded holes are opened on the surface of the door panel in a circular array; a socket is arranged on an inner side surface of the installation cavity; the electric baffle comprises an electric telescopic rod and a smoke-sealing baffle; the electric telescopic rod is plug-connected with the smoke-sealing baffle.

[0011] Furthermore, both surfaces of the smoke-sealing baffle are provided with mounting grooves; a bidirectional motor is fixedly connected to the bottom surface of the mounting groove; and a connecting plate is fixedly connected to the output end of the bidirectional motor.

[0012] Furthermore, annular brush plates are fixedly connected to both ends of the connecting plate; and a plurality of bristles are fixedly connected to the surface of the annular brush plate.

[0013] The present invention has the following beneficial effects:

[0014] The present invention transmits an alarm signal to a controller through a smoke sensor, thereby realizing control of the telescopic movement of the electric telescopic rod by a control box, driving the smoke barrier to block the vent. At this time, the socket is inserted into the plug, and the bidirectional motor is energized to drive the annular brush plate to rotate and clean the dust on the surface of the ventilation plate. When the alarm is lifted, the smoke sensor transmits a non-alarm signal to the controller, controlling the electric telescopic rod to pull the smoke barrier away from the vent. The ventilation effect of the fire door is effectively achieved, the function of autonomously closing and opening the vent is realized, and the dust in the vent is cleaned, thereby improving the ventilation effect.
