During the initial rotation of the transmission shaft 304, the turntable 309 on the surface begins to rotate. The rotation of the turntable 309 drives the positioning protrusion 3091 on the side wall to change its position, and it can contact the push plate 308. The push plate 308 moves horizontally at this time. After the push plate 308 moves to a certain extent, the push plate 308 is directly adsorbed and moved by the electromagnet 3081, and the push plate 308 and the positioning protrusion 3091 are separated. In the process of the movement of the insertion rod 307, the reset spring 3072 of the side wall is synchronously compressed to facilitate the later reset.

[0052] Embodiment 3:

[0053] The difference between the above embodiment and this embodiment is that: Figure 3 , Figure 4 , Fig. 9 and Fig.10As shown, a bearing is clamped on the bottom of the rotating shaft 3121, a bearing seat 3122 is clamped on the outer wall of the bearing, the bearing seat 3122 is welded to the back of the fireproof outer cover 301, a sound hole 3012 is opened on the outer wall of the fireproof outer cover 301, and the protective cover 312 covers the sound hole 3012.

[0054] like Figure 7 As shown, in a specific embodiment, the driving motor 302 is installed on the outer wall of the fireproof housing 301, and the output shaft of the driving motor 302 is installed with a guide shaft 3021, the guide shaft 3021 movably penetrates the side wall of the fireproof housing 301, and the end of the guide shaft 3021 is movably provided with a mounting seat 3022, and the mounting seat 3022 is welded and installed on the inner wall of the fireproof housing 301. Start the driving motor 302, and the driving motor 302 rotates to drive the guide shaft 3021 on the surface to rotate, and the worm 303 is installed on the guide shaft 3021, thereby driving the worm 303 to rotate.

[0055] like Figure 7 and Figure 8 As shown, further, a positioning plate 310 is movably provided through the side wall of the guide shaft 3021, and the positioning plate 310 is welded to the inner wall of the fireproof housing 301. Two inclined tracks 3101 are provided on the positioning plate 310, and one side of the inclined track 3101 is smoothly connected to the positioning plate 310, and two sounding boards 3102 are fixedly provided on the positioning plate 310. A bracket 311 is fixedly provided on the outer wall of the guide shaft 3021, and a positioning sleeve 3111 is fixedly provided on the bracket 311. A top rod 3112 is movably inserted inside the positioning sleeve 3111, and a spring is clamped between one side of the top rod 3112 and the positioning sleeve 3111, and a knocking head 3113 is fixedly provided at the end of the top rod 3112, and the knocking head 3113 is in contact with the sounding board 3102. During the rotation of the guide shaft 3021, the position of the positioning plate 310 of the side wall remains unchanged, while the bracket 311, the positioning sleeve 3111 and the top rod 3112 rotate and move along the inclined track 3101. When it moves to the highest point, the top rod 3112 is compressed. After moving to the end of the inclined track 3101, the top rod 3112 is pushed by a spring to accelerate the movement toward the positioning plate 310, and a sound is made by the contact between the knocking head 3113 and the sound board 3102, which serves as an alarm when the roller shutter is lowered to warn other people. This mechanical method can sound an alarm in a severe fire environment. Because it is a purely mechanical structure, it has strong reliability.

[0056] The present invention also discloses a cargo conveying device for passing through fire partitions, such as Figure 1 and Fig.10As shown, a cargo conveying unit 200 is installed at the bottom of the outer frame 100 of the fire partition, and the cargo conveying unit 200 includes a plurality of conveying rollers 201, a pulley 202 is installed at the rotation center of each conveying roller 201, and a belt 2023 is clamped on the adjacent pulleys 202, and a conveying motor 203 is installed at the rotation center of one of the conveying rollers 201; wherein the conveying motor drives the pulley to rotate, and the pulley drives a plurality of pairs of conveying rollers to rotate through the belt, so as to achieve the purpose of emergency conveying of cargo at the fire scene and reduce property loss, a first clamping groove 2021 and a second clamping groove 2022 are opened on the pulley 202, and a belt 2023 is clamped on the first clamping groove 2021 and the second clamping groove 2022, and each belt 2023 is connected to a different pulley 202, and a rotating shaft 2011 is installed at the center of the pulley 202, the rotating shaft 2011 is fixedly connected to the rotation center of the conveying roller 201, and a rotating shaft 2011 and an output end of the conveying motor 203 are connected to each other. The operator needs to transport the product as a whole to the conveyor roller 201, and then start the conveyor motor 203, and the conveyor motor 203 drives the rotating shaft 2011 to start rotating, and the conveyor roller 201 at the end of the rotating shaft 2011 starts to rotate, and the pulley 202 on the conveyor roller 201 drives the pulley 202 on the other side to rotate through the belt, and so on, and finally all the conveyor rollers 201 can rotate in the same direction, and then the goods on the surface can be transported as a whole.

[0057] The implementation principle of a fire protection structure and cargo conveying device that passes through fire protection partitions in this embodiment is as follows:

[0058] When a fire occurs, the operator needs to transport the entire product to the conveyor roller 201, and then start the conveyor motor 203. The conveyor motor 203 drives the rotating shaft 2011 to start rotating, and the conveyor roller 201 at the end of the rotating shaft 2011 starts to rotate, and the pulley 202 on the conveyor roller 201 drives the pulley 202 on the other side to rotate through the belt, and so on. Eventually, all the conveyor rollers 201 can rotate in the same direction, and the goods on the surface can be transported as a whole.

[0059] After the goods are delivered, the fire partition needs to be divided as a whole. The user first needs to start the drive motor 302. The rotation of the drive motor 302 drives the guide shaft 3021 on the surface to rotate, and the worm 303 is installed on the guide shaft 3021, thereby driving the worm 303 to rotate and meshing with the worm wheel 3031, driving the transmission shaft 304 of the side wall to rotate, and the transmission shaft 304 drives the winding roller 3041 on the surface to rotate, and during the winding process of the winding roller 3041, the rolling curtain 3042 wrapped on the surface begins to move downward. The guide roller 3043 is used to ensure that the rolling curtain 3042 moves vertically downward, and the counterweight plate 305 at the bottom pulls the rolling curtain to move vertically, and the guide slider 3051 on the side wall moves inside the guide slide groove 3052, and the rolling curtain 3042 is lowered as a whole, thereby achieving the purpose of dividing the fire partition.

[0060] During the initial rotation of the transmission shaft 304, the turntable 309 on the surface begins to rotate. The rotation of the turntable 309 drives the positioning protrusion 3091 of the side wall to change its position, and it can contact the push plate 308. The push plate 308 moves horizontally at this time. After the push plate 308 moves to a certain extent, the push plate 308 is directly adsorbed and moved by the electromagnet 3081, and the push plate 308 and the positioning protrusion 3091 are separated. In the process of the movement of the insertion rod 307, the reset spring 3072 of the side wall is compressed synchronously to facilitate the later reset. When the insertion rod 307 moves, the synchronous plate 3061 and the sealing plate 306 of the side wall move synchronously, and the sealing plate 306 and the gap 3011 are separated, so that the rolling shutter 3042 can slide down smoothly, and when the gap 3011 is not opened, the sealing plate 306 mainly plays a sealing and dustproof effect.

[0061] The seesaw 313 is originally in contact with the synchronous plate 3061. After the synchronous plate 3061 moves, the seesaw 313 is driven to rotate by the torsion spring 3131, and the protective cover 312 is driven to flip by the rotating shaft 3121. After the protective cover 312 flips, the drive motor 302 can be wrapped and protected as a whole, reducing the impact of the fire on it. When the protective cover 312 and the drive motor 302 are not in contact, the drive motor 302 is exposed to the outside, which is convenient for later maintenance. After the protective cover 312 flips, the sound transmission hole 3012 on the surface is opened, which is convenient for the alarm to be issued later. When the protective cover 312 needs to be reset, manual operation is required, because after the above situation occurs, it means that a fire has occurred, so it is necessary to check whether the equipment is damaged after the fire is over, and then the protective cover 312 can be reset at this time.

[0062] During the rotation of the guide shaft 3021, the position of the positioning plate 310 of the side wall remains unchanged, while the bracket 311, the positioning sleeve 3111 and the top rod 3112 rotate and move along the inclined track 3101. When it moves to the highest point, the top rod 3112 is compressed. After moving to the end of the inclined track 3101, the top rod 3112 is pushed by a spring to accelerate the movement toward the positioning plate 310, and a sound is made by the contact between the knocking head 3113 and the sound board 3102, which serves as an alarm when the roller shutter is lowered to warn other people. This mechanical method can sound an alarm in a severe fire environment. Because it is a purely mechanical structure, it has strong reliability.
