When the lifting member moves downward, the telescopic member is in the extended state, driving the second sleeve, the third sleeve, and the fourth sleeve to all slide downward. Also, when the lifting member moves upward, the telescopic member is in the retracted state, driving the second sleeve, the third sleeve, and the fourth sleeve to all slide upward. Therefore, the height of the frame can be changed, thereby changing the height of the fire extinguishing mechanism, and fires can be extinguished at different height positions.

[0020] 3.

And the output end of the second stepper motor drives the second lead screw to rotate, causing the movable plate to move left and right. When moving left, several sliding plates slide, and several second telescopic members are in the contracted state. When the first sleeve rotates, it is equivalent to reducing the "radius". When moving right, several second telescopic members are in the extended state. When the first sleeve rotates, it is equivalent to expanding the "radius". To a certain extent, the fire extinguishing range is also expanded.

[0021] 4. The present invention uses a temperature monitor to monitor the temperature inside the dichlorosilane gas cabinet in real time and uses carbon dioxide as the fire extinguishing agent, which can quickly and effectively extinguish fires. And the whole process is automated and does not require manual operation to open the equipment. Moreover, in a closed space, it can effectively avoid greater losses caused by fires triggered by dichlorosilane gas, changing the way of using traditional fire extinguishers manually and avoiding the situation of being injured during manual use.

The outer surface of the first sleeve 104 is rotatably connected to a driven wheel 110, and the driving wheel 109 is transmission-connected to the driven wheel 110 via a belt 111.

[0045] Please refer to Figure 4 and Figure 5 As shown, the lifting mechanism 3 includes a first stepper motor 301, a first screw rod 302, a lifting member 306 and a first telescopic member 309. The first stepper motor 301 is fixedly installed on the inner wall of the first sleeve 104. The inner wall of the first sleeve 104 is also fixedly connected to a fixing bar 303. One end of the first screw rod 302 is fixedly connected to the output end of the first stepper motor 301, and the other end of the first screw rod 302 is rotatably connected to the inside of the fixing bar 303.

[0048] Those skilled in the art can understand that the output end of the first stepping motor 301 drives the first lead screw 302 to rotate, so that the lifting member 306 moves up and down. When the lifting member 306 moves downward, the telescopic member 409 is in a stretched state, driving the second sleeve 109, the third sleeve 110 and the fourth sleeve 111 to all slide downward. And when the lifting member 406 moves upward, the telescopic member 409 is in a retracted state, driving the second sleeve 109, the third sleeve 110 and the fourth sleeve 111 to all slide upward. Therefore, the height of the frame 113 can be changed, thereby changing the height of the fire extinguishing mechanism 4, and fire extinguishing can be carried out at different height positions.

[0049] Embodiment 3

[0050] Please refer to Figure 7 As shown, the fire extinguishing mechanism 4 includes a second lead screw 401 and a guide rod 402. The second lead screw 401 is rotatably connected to the inner top end of the frame 113. The guide rod 402 is fixedly connected to the inner bottom end of the frame 113.

[0051] Please refer to Figure 7 As shown, a movable plate 404 is threadedly connected to the outer surface of the second lead screw 401.

A plurality of groups of sliding plates 406 are arranged between the fixed plate 405 and the movable plate 404. And fire extinguishing nozzles 407 are installed on the movable plate 404, the fixed plate 405 and the sliding plates 406.

[0052] Please refer to Figure 7As shown, second telescopic members 408 are provided between the fixed plate 405 and the sliding plate 406, between adjacent two groups of sliding plates 406, and between the sliding plate 406 and the movable plate 404.

A second stepping motor 403 is fixedly installed on the outer side of the frame 113. The output end of the second stepping motor 403 extends to the inside of the frame 113 and is fixedly connected to one end of the second lead screw 401.

[0053] Those skilled in the art can understand that by driving the output end of the driving motor 108 to drive the driving wheel 109 to rotate, the driven wheel 110 and the first sleeve 104 rotate as a whole, realizing the change of the orientation of the fire extinguishing nozzle 407, thus expanding the fire extinguishing range. And by driving the output end of the second stepping motor 403 to drive the second lead screw 401 to rotate, the movable plate 404 moves left and right. When moving to the left, several groups of sliding plates 406 slide, and several groups of second telescopic members 408 are in a contracted state. When the first sleeve 104 rotates, it is equivalent to reducing the "radius". When moving to the right, several groups of second telescopic members 408 are in an extended state. When the first sleeve 104 rotates, it is equivalent to expanding the "radius", which also expands the fire extinguishing range to a certain extent.

[0054] Working principle and usage process of the device: In the present invention, the output end of the drive motor 204 drives the overall rotation of the rotating rod 202 and the gear 203. As a result, the rack 205 moves to the right, causing the movable frame 206 to move. Due to the provision of the L-shaped groove 210, the connecting arm 207 rotates, causing the cover plate 208 to first move linearly and disengage from the notch opened on the left side of the dichlorosilane gas cabinet 1, and then the cover plate 208 moves upward to open the dichlorosilane gas cabinet 1, facilitating the staff to place the carbon dioxide fire extinguisher 101 inside the dichlorosilane gas cabinet 1. Subsequently, the dichlorosilane gas cabinet 1 is closed. During operation, the temperature monitor 112 monitors the temperature inside the dichlorosilane gas cabinet 1 in real time. The output end of the first stepping motor 301 drives the first lead screw 302 to rotate, causing the lifting member 306 to move up and down. When the lifting member 306 moves downward, the telescopic member 409 is in a stretched state, driving the second sleeve 109, the third sleeve 110, and the fourth sleeve 111 to all slide downward. When the lifting member 406 moves upward, the telescopic member 409 is in a retracted state, driving the second sleeve 109, the third sleeve 110, and the fourth sleeve 111 to all slide upward. Therefore, the height of the frame 113 can be changed, thereby changing the height of the fire extinguishing mechanism 4, enabling fire extinguishing at different height positions. Also, the output end of the drive motor 108 drives the drive wheel 109 to rotate, causing the driven wheel 110 and the first sleeve 104 to rotate as a whole, achieving a change in the orientation of the fire extinguishing nozzle 407, thereby expanding the fire extinguishing range. Moreover, the output end of the second stepping motor 403 drives the second lead screw 401 to rotate, causing the movable plate 404 to move left and right. When moving to the left, several sliding plates 406 slide, and several second telescopic members 408 are in a contracted state. When the first sleeve 104 rotates, it is equivalent to reducing the "radius". When moving to the right, several second telescopic members 408 are in a stretched state. When the first sleeve 104 rotates, it is equivalent to expanding the "radius". To a certain extent, the fire extinguishing range is also expanded, with no dead corners, and it has wide practicability. In addition, the present invention uses carbon dioxide as the fire extinguishing agent, which can quickly and effectively extinguish fires. The whole process is automated and does not require manual opening of the device. In a closed space, it effectively avoids greater losses caused by fires triggered by dichlorosilane gas, changes the way of using traditional fire extinguishers manually, and avoids the occurrence of situations where manual use causes harm.
