[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. In this invention, through the dynamically adjustable components, when the external wind speed and airflow act on the outer periphery of the outer casing, the anemometer detects the flow direction of the external wind speed and airflow. Under the action of the external wind speed and airflow, the anemometer, connecting shaft, second gear, first gear, first ring gear, first ring block, circular frame, and second air outlet rotate, moving the second air outlet to a position where the external wind speed and airflow directly act on one side of the outer casing. The exhaust unit extracts the heated gas inside the inner casing and heats it through an auxiliary heater. Then, the heated gas is delivered through the second air outlet to the space between the outer casing and the inner casing. The auxiliary heater counteracts the external low temperature, maintaining the operating temperature range of the internal electronic components. Furthermore, by dynamically adjusting the position of the second air outlet, the heated airflow accurately covers the area impacted by the external cold airflow, reducing overall energy consumption and helping to reduce the long-term impact of the external cold airflow on one side of the outer casing, reducing the temperature difference between the outer casing and the inner casing, thereby ensuring the reliability of the equipment in cold environments.

[0028] 2. In this invention, by setting a trigger heating component, when the camera unit is used at night in a cold region, the sensor will detect the temperature of the cold external region and cause the heating unit inside the heating box to heat up, providing auxiliary heating to the gas inside the connecting channel and air inlet pipe. The spiral blades convert the direct current gas inside the heating box into a spiral airflow, making the airflow evenly contact the heating box wall, promoting the mixing of the inner and outer layers of the airflow, reducing its axial temperature difference, and thus ensuring the uniformity of heating of the internal airflow entering the heat conduction ring, further improving the overall antifreeze effect of the equipment. Afterwards, it is sequentially transported to the heat conduction ring through the connecting pipe, where the heat conduction ring absorbs the heat and transfers it to the heat conduction module inside the lens of the camera unit to provide auxiliary heating to the edge of the lens of the camera unit, reducing the edge condensation effect of the lens inside the camera unit during use, thereby preventing the impact on the overall service life of the equipment. The outer shell and inner shell form a double-layer protective mechanism, reducing condensation and water vapor caused by the temperature difference between the inner and outer shells. Afterwards, the gas inside the heat conduction ring is transported to the inner shell through its internal mesh frame to help improve the energy utilization rate of the equipment during use.

[0029] 3. In this invention, through the protective components, when the external environment is harsh or the equipment is not used for a long time, the drive motor drives the rotating shaft, the fourth gear, the third ring gear, the fixed ring, the second ring gear, and the third gear to rotate, causing multiple sealing plates to seal the lens of the camera unit. By physically isolating the lens surface, snow or ice accumulation is prevented, and a local sealed space is formed at the lens, reducing the direct contact between the lens and the external cold air. This reduces the risk of internal fogging or freezing and cracking of the lens due to temperature differences. At the same time, the sealing plates drive the cleaning blocks to clean the lens surface, helping to remove dust, snow residue, or condensation, maintaining image clarity, and thus effectively improving the equipment's survivability and image quality in cold weather.

The top of the connecting shaft 411 extends to the outside of the outer shell 1 and is fixedly connected to an anemometer 412. The anemometer 412 and the second gear 410 are rotated by external airflow to adjust the triggering state between the first annular block 405 and the air supply unit. A heat preservation channel 7 is provided between the outer shell 1 and the inner shell. A heater and a fan are provided on one side inside the inner shell, and the output end of the fan is connected to the heat preservation channel 7. A protective cover 8 is provided on the top of the outer shell 1, and one side of the bottom of the outer shell 1 is fixed with screws. A mounting bracket 9 is connected to the camera unit 3. A lens is located on one side of the camera unit 3, and multiple supplementary lights are arranged in a circular array on the outer side of the lens. A connecting channel is opened on one side inside the mounting cover 2, which is connected to the insulation channel 7. A first annular block 405 is located on the side away from the connecting box 401. Multiple first air outlets 402 are arranged in a circular array on the side of the connecting box 401 away from the first annular block 405, and the first air outlets 402 are connected to the insulation channel 7. The supplementary air unit includes a circular frame 406, and the outer periphery of the circular frame 406 is connected to the first annular block 405. 5. The inner circumferential side is fixedly connected. The circular frame 406 is equipped with an exhaust unit and an auxiliary heater. The cross-sectional shape of the circular frame 406 is T-shaped. Multiple second air outlets 407 are arranged in a circular array on one side of the bottom of the circular frame 406. The second air outlets 407 are located on the side away from the first annular block 405. The circular frame 406 is rotatably sealed inside the connecting box 401. The first gear 408 is fixedly connected to a fixed shaft 409. The fixed shaft 409 is rotatably connected inside the inner shell. The connecting shaft 411 is rotatably connected inside the inner shell and the outer shell 1.

[0045] Detailed Implementation: When external wind speed and airflow act on the outer periphery of the outer casing 1, the anemometer 412 detects the flow direction of the external wind speed and airflow. Under the action of the external wind speed and airflow, the anemometer 412 and the connecting shaft 411 rotate. Utilizing the linkage effect between the connecting shaft 411 and the second gear 410, power is transmitted to the second gear 410, causing the second gear 410 to drive the first gear 408 to rotate. This causes the first gear 408 to drive the first ring gear 404, the first ring block 405, the circular frame 406, and the second air outlet 407 to rotate, moving the second air outlet 407 to a position where the external wind speed and airflow directly act on the side of the outer casing 1. The exhaust unit then... The heated gas inside the inner shell is extracted and heated by an auxiliary heater. The heated gas is then delivered through the second air outlet 407 to the space between the outer shell 1 and the inner shell. The auxiliary heater counteracts the low external temperature, maintaining the operating temperature range of the internal electronic components. By dynamically adjusting the position of the second air outlet 407, the heated airflow accurately covers the area impacted by the cold external airflow, reducing overall energy consumption and minimizing the long-term impact of the cold external airflow on one side of the outer shell 1. This also reduces the temperature difference between the outer shell 1 and the inner shell, thereby ensuring the reliability of the equipment in cold environments. The anemometer 412 is installed below the outer shell 1 as needed.

[0046] The trigger heating assembly 5 includes four heating boxes 501 arranged in a circumferential array. One side of the heating box 501 is fixedly connected to the inner wall of the mounting cover 2, and the heating box 501 is located on the side opposite to the outer shell 1. One side of the heating box 501 is connected to the connecting channel through an air inlet pipe. The side of the heating box 501 away from the air inlet pipe is connected to a connecting pipe 503. The other end of the connecting pipe 503 is connected to a heat-conducting ring 504. The heat-conducting ring 504 is sleeved on the outer periphery of the lens of the camera unit 3, and one side of the heat-conducting ring 504 is fixedly connected to the inner wall of the mounting cover 2. The heating box 501 is provided with a spiral blade 502. The heating box 501 is provided with a heating unit. One side of the heating unit is electrically connected to a sensor 505 through a wire. The side of the sensor 505 is fixedly connected to the outer wall of the mounting cover 2. A mesh frame is provided on one side of the heat-conducting ring 504, and the mesh frame is located on the side opposite to the camera unit 3.

[0047] Detailed Implementation: When the camera unit 3 is used at night in a cold region, the sensor 505 detects the temperature of the cold external environment and activates the heating unit inside the heating chamber 501 to heat the gas inside the connecting channel and air inlet pipe. The spiral blades 502 convert the direct current gas inside the heating chamber 501 into a spiral airflow, ensuring uniform contact between the airflow and the wall of the heating chamber 501. This promotes mixing of the inner and outer layers of the airflow, reducing the axial temperature difference and ensuring uniform heating of the internal airflow entering the heat-conducting ring 504. This further improves the overall anti-freeze effect of the equipment. Subsequently, the gas flows sequentially through the connecting pipe 50... 3. The heat is delivered to the heat-conducting ring 504, which absorbs the heat and transfers it to the heat-conducting module inside the lens of the camera unit 3 to provide auxiliary heating to the edge of the lens of the camera unit 3. This reduces the edge condensation effect of the lens inside the camera unit 3 during use, thereby preventing any impact on the overall service life of the equipment. The outer shell 1 and the inner shell form a double-layer protective mechanism, reducing condensation and moisture caused by the temperature difference between the inner and outer shells. Afterward, the gas inside the heat-conducting ring 504 is delivered to the inner shell through its internal mesh frame to help improve the energy utilization rate of the equipment during use.

[0048] The protective component 6 includes a circular base 601, one side of which is fixedly connected to the outer wall of the mounting cover 2. The circular base 601 has an annular cross-sectional shape and is fitted onto the outer periphery of the lens of the camera unit 3. A fixing ring 602 is provided inside the circular base 601. One side of the fixing ring 602 is rotatably connected to the inside of the circular base 601 via a second annular block 610. A second annular gear 603 is fixedly connected to the inner periphery of the fixing ring 602. Multiple third gears 604 are arranged in a circular array around the second annular gear 603. A limiting shaft 605 is fixedly connected inside the third gear 604 and rotatably connected to the circular base. Inside 601, a sealing plate 606 is fixedly connected to one side of the limiting shaft 605. The sealing plate 606 is located on the side opposite to the camera unit 3. Multiple sealing plates 606 form a closed circle. A cleaning block 611 is fixedly connected to one side of the sealing plate 606. The cleaning block 611 is located on the side opposite to the camera unit 3. A third ring gear 607 is fixedly connected to the outer periphery of the fixing ring 602.

A drive motor 609 is fixedly connected to one end of the rotating shaft. One side of the drive motor 609 is fixedly connected to the inner wall of the circular seat 601.

[0049] Detailed Implementation: When the external environment is harsh or the equipment 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. Utilizing the linkage effect between the fourth gear 608 and the third ring gear 607, power is transmitted to the third ring gear 607, causing the third ring gear 607 to drive the fixed ring 602 and the second ring gear 603 to rotate. Then, utilizing the linkage effect between the second ring gear 603 and the third gear 604, power is transmitted to the third gear 604, causing the third gear 604 to drive the limiting shaft 605 and the closing plate 606 to rotate. Multiple closing plates 60... The 6th sealing plate will seal the lens of the camera unit 3, physically isolating the lens surface to prevent snow or ice from covering it, forming a local sealed space at the lens, reducing direct contact between the lens and the outside cold air, and reducing the risk of internal fogging or freezing cracking of the lens due to temperature difference. At the same time, the sealing plate 606 drives the cleaning block 611 to clean the lens surface, helping to remove dust, snow residue or condensation, and maintaining image clarity. This can effectively improve the equipment's survivability and image quality in cold weather. As needed, an air blowing unit is set on one side of the cleaning block 611. During the process of the sealing plate 606 driving the cleaning block 611 to clean the lens surface, the air blowing unit assists in cleaning.

[0050] Working principle: During use, the housing 1 and camera unit 3 are installed in a suitable position on the outdoor roof using the mounting bracket 9. When the camera unit 3 is used in cold regions, especially at night, the sensor 505 will detect the temperature of the cold region and cause the heating unit inside the heating box 501 to heat the gas inside the connecting channel and air inlet pipe. The spiral blades 502 convert the direct current gas inside the heating box 501 into a spiral airflow, which is then transported to the heat conduction ring 504 through the connecting pipe 503. The heat conduction ring 504 absorbs the heat and transfers it to the heat conduction module inside the lens of the camera unit 3 to provide auxiliary heating to the edge of the lens of the camera unit 3.

[0051] When the external wind speed and airflow act on the outer periphery of the outer shell 1, the anemometer 412 will detect the flow direction of the external wind speed and airflow. Under the action of the external wind speed and airflow, the anemometer 412 and the connecting shaft 411 will rotate. Utilizing the linkage effect between the connecting shaft 411 and the second gear 410, the power is transmitted to the second gear 410, causing the second gear 410 to drive the first gear 408 to rotate. This causes the first gear 408 to drive the first ring gear 404, the first ring block 405, the circular frame 406, and the second air outlet 407 to rotate, moving the second air outlet 407 to a position where the external wind speed and airflow directly act on the side of the outer shell 1. The exhaust unit will extract the heated gas inside the inner shell and heat it through an auxiliary heater. Then, the heated gas will be delivered through the second air outlet 407 to the space between the outer shell 1 and the inner shell, thus helping to reduce the long-term impact of the cold external airflow on the side of the outer shell 1.

[0052] When the external environment is harsh or the equipment 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. Utilizing the linkage effect between the fourth gear 608 and the third ring gear 607, the power is transmitted to the third ring gear 607, causing the third ring gear 607 to drive the fixed ring 602 and the second ring gear 603 to rotate. Then, utilizing the linkage effect between the second ring gear 603 and the third gear 604, the power is transmitted to the third gear 604, causing the third gear 604 to drive the limit shaft 605 and the sealing plate 606 to rotate. Multiple sealing plates 606 will seal the lens of the camera unit 3. At the same time, the sealing plates 606 drive the cleaning block 611 to clean the lens surface, which is convenient to use.
