The protection assembly 34 comprises an inner transparent glass protective cover 341 and an outer transparent glass protective cover 342 fixedly sleeved outside the inner transparent glass protective cover 341, a ventilation gap 343 is formed between the inner transparent glass protective cover 341 and the outer transparent glass protective cover 342, a ventilation assembly 344 is further arranged above the inner transparent glass protective cover 341, the ventilation assembly 344 and the inner transparent glass protective cover 341 are connected through a pipe bundle assembly, the inside of the inner transparent glass protective cover 341 is a hollow structure and is in a vacuum state.

[0055] The application further provides a use method of the intelligent campus safety monitoring device.

[0056] Step 1, before installation, the first track assembly 1 and the second track assembly 2 are disassembled and sleeved on the installation rod or the installation column, then the first track assembly 1 and the second track assembly 2 are connected and fixed, and then the installation rod or the installation column is connected;

[0057] Step 2, the monitoring mechanism 3 slides along the loop rail mechanism formed by the first track assembly 1 and the second track assembly 2. In order to facilitate the laying of power lines and prevent the lines from entangling with each other, the monitoring mechanism 3 reverses its rotation before completing a full 360-degree rotation. This avoids the obstruction of installation poles or columns and facilitates the erection of the circuit. Since the motor power supply on the loop track is a mature technology, it is not described here.

[0058] Step 3, when the monitoring mechanism 3 moves in the clockwise direction, external air enters the interior of the monitoring mechanism 3 after being filtered and dried to perform cooling work. When the monitoring mechanism 3 moves in the counterclockwise direction, the outer wall is treated for defogging according to the working environment to eliminate the picture ghosting effect caused by water mist.

[0059] The specific process is as follows: since the two ends of the second track assembly 2 and the first track assembly 1 are connected through the semicircular loop bearing sleeve 21, when installed on the installation pole or column, the second track assembly 2 and the first track assembly 1 can be temporarily disassembled, then the second track assembly 2 and the first track assembly 1 are sleeved on the installation column or installation pole, and the semicircular loop bearing sleeve 21 at the two ends of the second track assembly 2 and the first track assembly 1 is connected again by bolts.

[0060] Then, according to the distance between the second track assembly 2 and the first track assembly 1 and the outer wall of the installation column or installation pole, the length of the first telescopic mounting bracket 26 and the second telescopic mounting bracket 27 is flexibly adjusted. After the length adjustment is completed, one end of the first telescopic mounting bracket 26 and the second telescopic mounting bracket 27 is connected to the installation column or installation pole.

[0061] When monitoring the campus, the control module in the intelligent controller 38 controls the output shaft of the micro motor 36 to rotate forward or reverse intermittently according to the preset instructions. When the output shaft of the micro motor 36 rotates forward, since the second gear 37 and the semicircular rack 25 are meshed and connected, the second gear 37 can drive the monitoring mechanism 3 to move as a whole under the reverse driving force of the semicircular rack 25 when the second gear 37 rotates. The sliding sleeve 35 slides along the outer wall of the semicircular slide rail 24. When the monitoring mechanism 3 has completed the entire monitoring of the designated area and has not rotated a full circle, it reverses its rotation and returns to the original position again. This process is repeated.

[0062] When the monitoring mechanism 3 rotates forward around the annular guide rail mechanism, the arc-shaped rack 23 drives the first gear 3443 to rotate, and the accelerator 3442 accelerates the rotation speed of the first gear 3443 to drive the impeller 3444 to rotate rapidly. The air in the cylinder 3441 is discharged upward through the exhaust port at the top of the cylinder 3441, forming a low pressure area below the impeller 3444 and a high pressure area above. Since the second one-way valve 348 only allows the gas inside the cylinder 3441 to flow outward, the air between the monitoring dome camera 33 and the inner transparent glass protective cover 341 is sucked into the cylinder 3441 through the two heat dissipation ventilation pipes 349 and discharged through the exhaust port. The external air is filtered, dried by the air filter 39, and then enters the interior of the protective shell 32, and then enters the space between the monitoring dome camera 33 and the inner transparent glass protective cover 341 through the cooling channel at the bottom of the protective shell 32 and between the inner transparent glass protective cover 341 and the monitoring dome camera 33. After the protective shell 32 and the monitoring dome camera 33 are cooled by this part of cold air, they are sucked into the cylinder 3441 again by the heat dissipation ventilation pipe 349 and discharged through the exhaust port at the top of the cylinder 3441.

[0063] When the monitoring mechanism 3 rotates reversely around the annular guide rail mechanism, the wind generated by the rotation of the impeller 3444 blows downward to the cylinder 3441. The area above the impeller 3444 forms a low pressure area, and the area below forms a high pressure area. The gas in the ventilation gap 343 is sucked into the cylinder 3441 through the suction pipe 345, and the gas sucked into the cylinder 3441 is heated by the heating wire 3446 and then input into the ventilation gap 343 again through the hot air conveying pipe 347. After the heated gas enters the outer transparent glass protective cover 342, it heats the outer transparent glass protective cover 342. Since the inner transparent glass protective cover 341 is in a vacuum state, it has good heat insulation capacity. The water mist attached to the outer wall of the outer transparent glass protective cover 342 evaporates quickly after being heated, avoiding the influence of the water mist on the image capture of the monitoring dome camera 33.
