[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In the present invention, through the provided dynamic adjustment component, when the external wind speed airflow acts on the outer periphery of the outer shell, the anemometer will detect the flow direction of the external wind speed airflow, and under the action of the external wind speed airflow, the anemometer, connecting shaft, second gear, first gear, first annular gear, first annular block, circular frame, and second air outlet will rotate, moving the second air outlet to the side where the external wind speed airflow directly acts on the outer shell. The air extraction unit will extract the heated gas inside the inner shell, heat it through the auxiliary heater, and then transport the heated gas to the space between the outer shell and the inner shell through the second air outlet. The auxiliary heater offsets the external low temperature to maintain the operating temperature range of the internal electronic components. By dynamically adjusting the position of the second air outlet, the heated airflow precisely covers the area impacted by the external cold airflow, reducing the overall energy consumption, assisting in reducing the long-term impact of the external cold airflow on one side of the outer shell, reducing the temperature difference between the outer shell and the inner shell, and thus ensuring the reliability of the device in a cold environment.
[0016] 2. In the present invention, through the provided trigger heating component, when the camera unit is used at night in a cold region, the sensor will detect the temperature of the external cold region and cause the heating unit inside the heating box to heat up, assisting in heating the gas inside the connecting channel and the air inlet pipe. The spiral blade converts the direct current gas inside the heating box into a spiral airflow, enabling the airflow to uniformly contact the wall surface of the heating box, promoting the mixing of the inner and outer layers of the airflow, reducing its axial temperature difference, and thus ensuring the uniformity of the heating of the airflow entering the heat conduction ring. This further improves the overall anti-freezing effect of the device. Then, it is sequentially transported to the heat conduction ring through the connecting pipe. The heat conduction ring will absorb its heat and transfer it to the heat conduction module inside the lens of the camera unit to assist in heating the edge of the lens of the camera unit, reducing the edge condensation effect during the use of the lens inside the camera unit, and thus preventing the impact on the overall service life of the device. The outer shell and the inner shell form a double-layer protection mechanism, reducing the condensation and water vapor caused by the internal and external temperature difference between the inner shell and the outer shell. Then, the gas inside the heat conduction ring will be transported to the inside of the inner shell through the mesh frame inside it to assist in improving the energy utilization rate of the device during use.
[0017] 3. In the present invention, through the provided protection component, when the external environment is relatively harsh or when the device is not used for a long time, the driving motor drives the rotation of the rotating shaft, the fourth gear, the third annular gear, the fixing ring, the second annular gear and the third gear, so that a plurality of closing plates will close the lens of the imaging unit. By physically isolating the surface of the lens, snow or ice coverage is avoided, a local closed space is formed at the lens, direct contact between the lens and the external cold air is reduced, and the risk of internal fogging or cracking of the lens due to temperature difference is lowered. At the same time, the closing plate drives the cleaning block to clean the surface of the lens, assisting in removing dust, snow melting residues or condensed water, maintaining imaging clarity, and thus effectively improving the survival ability and imaging quality of the device in cold weather.

[0024] **Detailed implementation manner**: When the camera unit 3 is used at night in cold regions, the sensor 505 detects the temperature of the external cold region, and causes the heating unit inside the heating box 501 to heat up, assisting in heating the gas inside the connection channel and the air inlet pipe. The spiral blade 502 converts the direct current gas inside the heating box 501 into a spiral air flow, enabling the air flow to uniformly contact the wall surface of the heating box 501, promoting the mixing of the inner and outer layers of the air flow, reducing its axial temperature difference, and thus ensuring the uniform heating of the air flow entering the heat conduction ring 504, further improving the overall anti-freezing effect of the device.

[0026] Detailed implementation method: When the external environment is relatively harsh or when the device is not used for a long time, start the drive motor 609.

[0027] Working principle: When in use, the outer housing 1 and the imaging unit 3 are installed at a suitable position on the outdoor top through the mounting frame 9. When the imaging unit 3 is used in an external cold area, when the imaging unit 3 is used at night in a cold area, the sensor 505 will detect the temperature of the external cold area and cause the heating unit inside the heating box 501 to heat, assisting in heating the gas inside the connection channel and the air inlet pipe. The spiral blade 502 converts the direct current gas inside the heating box 501 into a spiral air flow. Then, it is sequentially transported to the heat conduction ring 504 through the connecting pipe 503. The heat conduction ring 504 absorbs its heat and transfers it to the heat conduction module inside the lens of the imaging unit 3 to assist in heating the edge of the lens of the imaging unit 3. When the external wind speed airflow acts on the outer peripheral side of the outer housing 1, the anemometer 412 will detect the flow direction of the external wind speed airflow at this time. And under the action of the external wind speed airflow, the anemometer 412 and the connecting shaft 411 rotate. By using the linkage effect between the connecting shaft 411 and the second gear 410, the power is transmitted to the second gear 410, so that the second gear 410 drives the first gear 408 to rotate, causing the first gear 408 to drive the first annular gear 404, the first annular block 405, the circular frame 406 and the second air outlet 407 to rotate, and moving the second air outlet 407 to the side where the external wind speed airflow directly acts on the outer housing 1. The air extraction unit will extract the hot gas inside the inner housing and heat it through the auxiliary heater. Then, the heated gas is conveyed to the space between the outer housing 1 and the inner housing through the second air outlet 407, which helps to reduce the influence of the external cold airflow on one side of the outer housing 1 for a long time; When the external environment is relatively harsh or when the device is not used for a long time, the drive motor 609 is started. The drive motor 609 drives the rotating shaft and the fourth gear 608 to rotate. By using the linkage effect between the fourth gear 608 and the third annular gear 607, the power is transmitted to the third annular gear 607, so that the third annular gear 607 drives the fixed ring 602 and the second annular gear 603 to rotate. Then, by using the linkage effect between the second annular gear 603 and the third gear 604, the power is transmitted to the third gear 604, so that the third gear 604 drives the limit shaft 605 and the closing plate 606 to rotate. Multiple closing plates 606 will close the lens of the imaging unit 3, and at the same time, the closing plate 606 drives the cleaning block 611 to clean the surface of the lens, which is convenient to use.
