The rear filter plate and the rear baffle form a whole, which is used to close the rear positions of the upper shell and the lower shell. The roller is used to reduce the friction when the camera body moves inside the lower shell.

[0010] Preferably, the protrusion cooperates with the first guide groove and the second guide groove, a U-shaped block is fixedly connected to the top of the camera body near the front surface, the bottom of the slider extends to below the hollow shell and the bottom of the slider is fixedly connected to the top of the U-shaped block, a friction ring is embedded in the rear surface of the U-shaped block, a guide rod is slidably arranged between the inner walls of the friction ring, the front end of the guide rod is fixedly connected to the rear surface of the built-in frame, and a reset spring is fixedly connected between the rear inner wall of the hollow shell and the rear surface of the slider.

[0015] By adopting the above technical solution, the arc groove cooperates with the arc block to connect the rotating ring and the annular member, and the rotating ring can rotate in a small range at the front end of the annular member, and the elastic force provided by the avoidance spring is used to control the position of the rotating ring at the front end of the annular member.

[0016] Preferably, the rotating shaft is rotatably connected to the center of the outer surface of the built-in frame and its two ends extend forward and rearward respectively. A first pinion is fixedly connected to the outer surface of the rotating shaft near the middle position, and a large gear is meshedly connected to the outer surface of the first pinion. The large gear is rotatably connected to the rear surface of the built-in frame, and a second pinion is fixedly connected to the front surface of the large gear through a shaft, and the second pinion is meshedly connected to the inner gear sleeve.

[0017] By adopting the above technical solution, the internal gear sleeve will drive the second pinion to rotate during rotation. During the rotation of the second pinion, the cooperation between the large gear and the first pinion will accelerate the rotation, thereby driving the shaft to rotate rapidly.

[0018] Preferably, a first fan blade is installed at the front end of the rotating shaft, and the first fan blade is located on the front side of the annular member. A second fan blade is installed on the outer surface of the rotating shaft near the rear end, and the rear end of the rotating shaft and the rear filter plate are rotatably connected via a bearing.

[0019] By adopting the above technical solution, the first fan blade and the second fan blade are mainly used to guide the air flow when they rotate along with the rotating shaft.

[0020] Preferably, a conical channel is fixedly connected at the center of the front surface of the annular plate, the front and rear ends of the conical channel are both provided with openings, and a filter screen is fixedly connected between the inner surface walls of the conical channel.

[0021] By adopting the above technical solution, the conical channel facilitates the discharge of internal impurities to the outside, the filter holes are moderate and do not affect the discharge of impurities, and the conical channel is narrow in front and wide in the back, making it difficult for external dust to enter the inside of the device.

[0025] By adopting the above technical solution, during the operation of the device, the lens will perform circular motion and the rotating gear will rotate. After the lens passes through the rotating gear, the soft brush can clean the dust on the front end of the lens and discharge the dust under the action of the exhaust component.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. When the present invention is used, after the servo motor is started to cooperate with the driving gear and the inner gear sleeve to drive the ring member to rotate, the three lens positions in the lens assembly will be switched. Under the action of the first guide groove and the second guide groove, the camera body will move backward to the maximum distance and then move forward under the action of the reset spring, thereby achieving the purpose of switching the camera body lens. Therefore, when an abnormal situation occurs at the airport, the camera body at the best monitoring angle can switch the lens according to the actual situation, thereby transmitting the best monitoring scene to the airport monitoring center, improving the monitoring effect.

[0028] 2. When the present invention is used, when the lens is switched, the annular member rotates, and there is a delay for the protrusion to enter the first guide groove from the second guide groove. At this time, the receiving end and the lens are not completely separated. If the lens is subjected to lateral pulling force, the arc block on the surface of the rotating ring will squeeze the avoidance spring to shrink it, so that the rotating ring and the lens will not immediately rotate with the annular member. When the receiving end and the lens are completely separated, the avoidance spring pushes the arc block back to the clockwise side of the arc groove, and the lens can normally follow the movement of the annular member to complete the next connection. This design structure is simple and effectively improves the stability and reliability of lens switching.

[0029] 3. When the present invention is in use, when the annular member rotates, the inner gear sleeve inside it drives the second small gear to accelerate the rotation, and the second small gear drives the large gear on the rear side of the built-in frame to rotate synchronously through the shaft, and the large gear in turn accelerates the rotation of the first small gear on the surface of the shaft, and the rapidly rotating shaft drives the first fan blade and the second fan blade to rotate rapidly on the front and rear sides of the upper shell respectively, so that external air is drawn into the device from the rear side and then sent out from the conical channel on the front side. In this process, the air will take away the internal heat of the device, realizing active heat dissipation without the need for an additional power source. This design cleverly utilizes the rotation of the annular member to achieve the heat dissipation function.

[0030] 4. When the present invention is used, when the lens is switched, the rotating ring rotates, so that the connecting frame on the front side of the mounting frame drives the outer gear sleeve to rotate, and the rotation of the outer gear sleeve drives multiple self-rotating gears on the rear side of the annular plate to rotate. When the telephoto, wide-angle, and standard lenses switch positions with the rotating ring, the outer end of the lens will contact the soft brush on the surface of the self-rotating gear, and the rotating soft brush can sweep away the dust on the outer end of the lens. At the same time, under the action of the first fan blade and the second fan blade, the fallen dust will be discharged from the conical channel with the airflow. This design combines the lens switching with the dust removal function, and no additional operation is required, and the dust removal effect is good. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] A plurality of arc blocks 406 are fixedly connected at equal intervals to the rear surface of the rotating ring 401. The arc blocks 406 are slidably embedded between the inner surface walls of the arc groove 206. An avoidance spring 407 is fixedly connected between the inner surface wall of the arc groove 206 and the outer surface of the arc block 406. Three groups of mounting frames 402 are equidistantly connected to the outer surface of the rotating ring 401. A telephoto lens 403, a wide-angle lens 404 and a standard lens 405 are fixedly installed on the outer sides of the three groups of mounting frames 402 through clamps. The rear ends of the telephoto lens 403, the wide-angle lens 404 and the standard lens 405 are all plugged into the receiving end 303. The arc block 406 cooperates with the arc groove 206 to flexibly connect the rotating ring 401 and the ring member 202. The avoidance spring 407 is used to push the arc block 406 to the clockwise side of the arc groove 206. When the rotating ring 401 rotates 120° following the ring member 202, the telephoto lens 403, the wide-angle lens 404 and the standard lens 405 are driven through the mounting bracket 402. The positions of the telephoto lens 403 and the standard lens 405 change.

During operation, the camera body 301 can adjust the monitoring angle and direction through the pan / tilt 15, and collect optical signals through the telephoto lens 403, the wide-angle lens 404 and the standard lens 405. After the optical signal is converted into an electrical signal through the image sensor in the camera body 301, the amplifier, filter and analog-to-digital converter in the signal processing circuit amplify and filter the signal, and then the analog electrical signal is converted into a digital signal, which is transmitted to the display screen in the airport command and monitoring center by wired / wireless means for display.

[0048] The use steps of the present invention are as follows: when in use, the servo motor 208 in the device can be started as needed to drive the driving gear 207 to rotate. Each time the driving gear 207 rotates, the inner gear sleeve 203 can drive the ring member 202 to rotate 120°. During the rotation of the ring member 202, the first guide groove 204 and the second guide groove 205 on the surface will rotate accordingly, and the protrusion 306 on the front side of the second guide groove 205 is restricted by the hollow shell 304 and can only move forward and backward. Therefore, the protrusion 306 will enter the inclined first guide groove 204 from the second guide groove 205, and as the first guide groove 204 runs, the protrusion 306 will gradually move backward. During the process, the protrusion 306 will drive the camera through the slider 305 and the U-shaped block 308. The camera body 301 moves backward and squeezes the return spring 307 to shrink until the protrusion 306 moves to the inside of the other second guide groove 205. The return spring 307 loses pressure and rebounds, thereby pushing the slider 305 to slide forward inside the hollow shell 304. In the process, the protrusion 306 and the camera body 301 move forward synchronously. At the same time, during the rotation of the annular member 202, the rotating ring 401 at its front end will drive the telephoto lens 403, the wide-angle lens 404 and the standard lens 405 to complete a position change in advance through the mounting bracket 402. When the camera body 301 has completed the forward movement, the receiving end 303 will be plugged into different lenses, so that the same camera body 301 can meet the needs of long-distance imaging and large-range close-up coverage. Imaging and natural perspective imaging, therefore, when an abnormal situation occurs at the airport, the camera body 301 at the best monitoring angle can switch the lens according to the actual situation, so as to transmit the best monitoring scene to the airport monitoring center, thereby improving the monitoring effect, and effectively reducing the production cost, installation and maintenance cost and information processing difficulty. This function of switching lenses according to the needs of different airport scenes has high intelligent adaptability and is more in line with the needs of smart airports for accurate and efficient monitoring. In addition, during the lens switching process, during the rotation of the ring member 202, there is a certain delay in the process of the protrusion 306 entering the first guide groove 204 from the second guide groove 205. At this time, the receiving end 303 and the lens are not completely separated. At this time, the lens When the head is subjected to lateral pulling force, the arc block 406 on the surface of the rotating ring 401 will squeeze the avoidance spring 407 to shrink, so that the rotating ring 401 and the lens will not immediately follow the rotation of the ring member 202. When the receiving end 303 and the lens are completely separated, the avoidance spring 407 will push the arc block 406 back to the clockwise side of the arc groove 206, so that the lens can normally follow the movement of the ring member 202 and complete the next connection. The design structure is simple and improves the stability and reliability of the lens switching process. At the same time, each time the lens is switched, the camera body 301 will first move to the rearmost position, and then move forward under the action of the reset spring 307, and the receiving end 303 will be plugged into the lens. Therefore,During the switching process, the telephoto lens 403, wide-angle lens 404 and standard lens 405 of different lengths can be stably plugged into the receiving end 303 of the camera body 301.

[0049] Embodiment 2: Figure 2-Figure 4 , Figure 6 and Fig. 9 As shown, the difference between the embodiment and the basis is that the shaft 501 is rotatably connected to the center of the outer surface of the built-in frame 201 and the two ends extend to the front and rear sides respectively. The outer surface of the shaft 501 is fixedly connected with a first pinion 502 near the middle position. The outer surface of the first pinion 502 is meshingly connected with a large gear 503. The large gear 503 is rotatably connected to the rear surface of the built-in frame 201. The front surface of the large gear 503 is fixedly connected with a second pinion 504 through an axis. The second pinion 504 is meshingly connected to the inner gear sleeve 203. The number of teeth of the inner gear sleeve 203 is six times the number of teeth of the second pinion 504. For every 120° rotation of the inner gear sleeve 203, the second pinion 504 will rotate two circles, and the number of teeth of the large gear 503 is five times the number of teeth of the first pinion 502. Therefore, the large gear 503 follows the second pinion 504 to rotate two circles, which will drive the first pinion 502 and the shaft 501 to rotate quickly ten circles.

[0050] A first fan blade 505 is installed at the front end of the rotating shaft 501, and the first fan blade 505 is located on the front side of the annular member 202.

The rear end of the rotating shaft 501 and the rear filter plate 14 are rotatably connected through a bearing. When the rotating shaft 501 rotates rapidly, it can drive the first fan blade 505 and the second fan blade 506 to rotate, thereby drawing external air in from the rear side and pushing it forward. The rear filter plate 14 can filter the incoming air.

[0051] A conical channel 602 is fixedly connected at the center of the front surface of the annular plate 601. The front and rear ends of the conical channel 602 are both opened. A filter screen 603 is fixedly connected between the inner surface walls of the conical channel 602. The conical channel 602 extends forward, and the front opening is smaller than the rear opening. Therefore, it is difficult for external dust and impurities to enter the interior of the device, while internal dust and impurities can be easily discharged outward. The mesh size of the filter screen 603 is moderate, which can further filter external impurities and will not block the discharge of internal impurities.

[0052] The use steps of the present invention are as follows: when the annular member 202 rotates, the inner gear sleeve 203 on the inner side of the annular member 202 drives the second pinion 504 to rotate faster. During the rotation of the second pinion 504, the large gear 503 on the rear side of the built-in frame 201 is driven to rotate synchronously through the shaft. During the rotation of the large gear 503, the first pinion 502 on the surface of the rotating shaft 501 is driven to rotate faster. At this time, the rapidly rotating rotating shaft 501 drives the first fan blade 505 and the second fan blade 506 to rotate rapidly at positions near the front and rear sides inside the upper shell 1, thereby drawing external air into the device from the rear side and sending it out from the front conical channel 602. During the process, the air will drive the heat inside the device, and active heat dissipation can be performed without the need for an additional power source.

[0053] Embodiment 3: Figure 2-Figure 4 , Figure 8 and Fig.10 As shown, the difference between the embodiment and the basis is that the annular plate 601 is fixedly installed on the front surface of the upper shell 1, and a transparent window 604 is provided on the outer surface of the annular plate 601 near the bottom, and the transparent window 604 corresponds to the position of the receiving end 303. The transparent window 604 on the surface of the annular plate 601 corresponds to the position of the receiving end 303, and the front end of the lens inserted into the receiving end 303 of the camera body 301 can pass through the transparent window 604 to collect external light signals. The annular plate 601 has the function of protecting the lens assembly 4.

[0054] The rear surface of the annular plate 601 is equidistantly connected to a plurality of self-rotating gears 605 near the edge, and a soft brush 606 is installed on the rear surface of the self-rotating gear 605. The soft brush 606 cooperates with the telephoto lens 403, the wide-angle lens 404 and the standard lens 405 respectively. The front surfaces of the three mounting frames 402 are fixedly connected to a connecting frame 408 extending forward near the middle position, and an outer gear sleeve 409 is fixedly connected between the front ends of the three connecting frames 408. The outer gear sleeve 409 is meshingly connected to the self-rotating gear 605, and the self-rotating gear 605 is meshingly connected to the outer gear sleeve 409. When the outer gear sleeve 409 rotates, all the self-rotating gears 605 will drive the soft brush 606 to rotate. When the lens moves in the process of switching positions, it will come into contact with the soft brush 606, so that the dust on the lens surface is swept away by the soft brush 606.

[0055] The use steps of the present invention are as follows: during the lens switching process, when the rotating ring 401 rotates, the connecting frame 408 on the front side of the mounting frame 402 will drive the outer gear sleeve 409 to rotate. When the outer gear sleeve 409 rotates, the multiple rotating and connected self-rotating gears 605 on the rear side of the annular plate 601 will be driven and rotate. When the telephoto lens 403, the wide-angle lens 404 and the standard lens 405 switch positions, since they follow the movement of the rotating ring 401, the outer end faces of the lenses will contact the soft brushes 606 on the surfaces of the multiple self-rotating gears 605. The soft brushes 606 that rotate with the self-rotating gears 605 will sweep away the dust on the outer end of the lens. Under the action of the first fan blade 505 and the second fan blade 506, the fallen dust will follow the airflow and be discharged from the conical channel 602, thereby having a good dust removal effect.

[0056] Among them, the pan / tilt head 15, the servo motor 208 and the camera body 301 are all existing technologies, and their components and operating principles are all public technologies, so no further explanation will be given here.
