therefore, in the scheme, the arranged guide rail 5 is fixedly connected with the mounting frame 1 through the rotating part, and in the daily use process, the guide rail 5 is rotated to be in a horizontal state through the arranged rotating part and is folded in the decorative plate of the roof, so that the guide rail 5 is hidden, and the attractiveness and the safety of the fireproof rolling door when the fireproof rolling door is installed in an atrium in a segmented mode are improved;

Meanwhile, when the fireproof rolling door is required to play a fireproof function; the information of the occurrence of the fire is sensed through the set triggering part, then the information is transmitted to the control part, the control part performs comparison and judgment according to the preset information in the control part, and gives out corresponding instructions to control the rotating part to drive the guide rail 5 to rotate, after the guide rail 5 rotates in place, the information of the occurrence of the fire is collected through the position collecting part, then the information is transmitted to the controller, after the information is received, the operation instruction is transmitted to the winding motor 3, the fireproof curtain 4 is controlled to fall along the guide rail 5 through the operation of the winding motor 3, so that the closing of the fireproof rolling door is realized, and the requirement of isolating the fire is met;

the problem that the guide rails 5 positioned in the middle are shared by the adjacent fireproof curtains 4 is solved, the arranged position acquisition component can simultaneously and respectively acquire the in-place conditions of all the guide rails 5, then the in-place information of the guide rails 5 at the corresponding positions is transmitted to the controller, the in-place conditions of all the guide rails 5 are processed in the controller, and when only the guide rails 5 on two sides of the fireproof curtain are in place, an instruction for controlling the fireproof curtain to fall is sent out, so that the fireproof roller shutter door can be smoothly closed; avoiding faults during the closing process.

The speed reducing motor 6 is a motor capable of reducing the rotation speed of the driving apparatus and increasing the torque output. The motor is generally composed of a motor and a speed reducer, and the high-speed rotation of the motor is converted into lower speed and larger torque of an output shaft through the speed reducer; the gear motor 6 operates as follows:

a motor part: the motor part of the gear motor 6 usually uses an ac motor or a dc motor, and different types of motors are selected according to the specific application requirements. The motor converts the electric energy into mechanical energy through the electric energy provided by the power supply, and generates rotating force.

A speed reducer section: the output shaft of the motor is connected with a speed reducer, and the speed reducer reduces the rotating speed of the motor and increases the torque of the output shaft through a series of gear transmission, belt transmission or chain transmission and the like. The working principle of the speed reducer mainly depends on the meshing between gears and the design of the transmission ratio.

In the scheme, the worm gear reduction motor 6 is preferably selected, so that larger torque transmission can be realized, the longer guide rail 5 is driven to rotate, meanwhile, the worm gear has a certain self-locking function, and when the guide rail 5 is in a descending state, the stability of the guide rod 19 can be increased due to self-locking of the reduction motor 6, and the smoothness of the fireproof curtain 4 in the descending state is further improved; in the retracted state of the guide rail 5, the self-locking of the gear motor 6 can prevent the guide rail 5 from falling off, so that the safety of the fireproof rolling door is improved;

when the power source for controlling the guide rail 5 to rotate and descend is selected, the power source can be an alternative scheme of a speed reducing motor 6, and can also be an electric push rod and a hydraulic rod, wherein the movable ends of the electric push rod and the hydraulic rod are hinged with the guide rail 5, and the guide rail 5 is pushed to rotate downwards by the extension of the electric push rod or the hydraulic rod; in this way a faster fall of the guide rail 5 can be achieved; the movable pulley is arranged on the guide rail 5 through the combination of the rope and the pulley, the fixed pulley is arranged on the mounting frame 1, and the guide rail 5 is folded and lowered in the vertical direction through folding and lowering the steel rope, so that the guide rail 5 can be more stable in the moving process by adopting the mode.

Because the guide rail 5 is in a state of being difficult to control in the downward movement process under the action of self gravity, the risk of damaging personnel or articles exists, and therefore, a certain judgment is needed when the situation of fire is urgent or not; the environment around the video acquisition can be adopted for comparison to determine whether a serious fire exists around; or a temperature sensor or a smoke sensor is arranged in the range of 5-10 meters of the setting position of the rolling door so as to determine the information of fire conditions, and a controller is used for comparing and judging whether the emergency drop requirement of the guide rail 5 is made.

When the shutter door works, in order to pursue timely effectiveness of fire prevention, the guide rail 5 is selected to swing in place rapidly under the action of gravity, so that the guide rail 5 swings downwards under the action of gravity in the falling process of the guide rail 5, is in an acceleration movement process, is limited after the guide rail 5 moves to a vertical position, and further the guide rail 5 is rapidly stopped, and at the moment, the guide rail 5 is caused to be subjected to the action of inertia to deform so as to influence the falling of the subsequent fire protection curtain 4 and influence the fire resistance of the shutter door;

therefore, in this scheme, through having seted up fresh air inlet 12 on the windward side of guide rail 5 (the windward side of this moment is the side of guide rail 5 windward in the downward swing in-process), and then in the in-process that guide rail 5 swings whereabouts, air enters into cavity 11 inside from fresh air inlet 12, and because the setting of check valve 13, then can make the inside gas of cavity 11 increase along with the increase of swing speed, and then make the inside pressure of cavity 11 increase, further can make the expansion part 14 that sets up in guide rail 5 bottom outwards warp expansion, so as to increase the length of guide rail 5, therefore when guide rail 5 has not moved in place yet, then expansion part 14 can be contacted with the ground earlier, and expansion part 14 can be impacted and extruded, with this absorption part's impact energy, in order to reach the effect of reducing the swing speed of guide rail 5, because expansion part 14 is flexible material, then when receiving the impact, more easily warp, consequently, can make the impact energy that guide rail 5 whereabouts in-process produced be preferentially by expansion part 14 pass through with the friction and the ground, and the guide rail 5 is not directly acted on the curtain that can be down to the deformation, and the fire curtain is guaranteed, the fire curtain is down, the fire curtain is guaranteed, and the fire curtain is smoothly can be down, the deformation is guaranteed, and the guide rail 5 is down, the risk of the deformation is guaranteed.
