[0038] The working principle of the power distribution cabinet safety alarm device of the present invention is as follows:

[0039] First, the connection housing 1 is embedded in the top side wall of the power distribution cabinet to install the design, so that the monitoring body 2 is located inside the power distribution cabinet, and the various sensors on the monitoring body 2 are used to monitor the inside of the power distribution cabinet for safety, and an alarm is issued through the sound and light alarm 35, and data communication is performed through the external monitoring system to remotely monitor and manage the status of the power distribution cabinet;

[0040] Second, after the present design is installed, the handle 322 can be rotated, and the first bevel gear 323 drives the threaded rod 325 to rotate by cooperating with the second bevel gear 324 under the rotation of the handle 322. Under the cooperation of the threaded rod 325 and the internal threaded sleeve 329, the height position of the top plate 3210 can be changed, and at the same time, the inner cylinder rod 3286 moves longitudinally in the outer cylinder rod 3285, thereby changing the height position of the cover seat 33 and the sound and light alarm 35, so that the monitoring structure 34 and the sound and light alarm 35 are adjusted to a position where they are not blocked by the surrounding environment for use;

[0041] Third, the electric push rod 342 can be operated to retract, and when the electric push rod 342 is retracted, the warehouse door 343 is driven to shift in an oblique downward trajectory, so that the warehouse door 343 is opened in the rectangular warehouse 341, and the swing rod 344 is caused to rotate through the contact between the warehouse door 343 and the swing rod 344, so that the swing rod 344 moves in the first positioning block 3451 and the second positioning block 3452 to push the shift block 345 to move to the outside of the rectangular warehouse 341, and after the shift block 345 is moved out, the camera 347 is driven to move out, and then the external environment is observed through the camera 347, and then the servo motor 3281 can be controlled to start. Under the action of the machine 3281, the driving pulley 3282 drives the driven pulley 3284 to rotate through the cooperation with the transmission belt 3283. When the driven pulley 3284 rotates, the outer cylinder rod 3285 and the inner cylinder rod 3286 drive the top plate 3210 to rotate, thereby improving the observation effect of the camera 347 on the external environment. When it is not necessary to observe the external environment, the electric push rod 342 is driven to reset so that the warehouse door 343 is closed on the side of the rectangular warehouse 341. After the warehouse door 343 is closed, the displacement block 345 is reset under the action of the tension spring 346, so that the camera 347 enters the interior of the rectangular warehouse 341, thereby reducing the damage caused by the external environment to the camera 347;

[0042] Fourth, during use, the column 36 is passed through the inner side of the positioning sleeve 373, the clamping claw 374 and the locking screw sleeve 375, and the locking screw sleeve 375 is moved downward by rotating the locking screw sleeve 375 on the inner side of the positioning sleeve 373 to hold the clamping claw 374 tightly on the column 36, thereby realizing the positioning of the disc 371 and the transparent cover sleeve 372 to protect them above the sound and light alarm 35, and the locking screw sleeve 375 can be unscrewed from the inner side of the positioning sleeve 373 to achieve disassembly and replacement.
