[0038] The base 21 is connected to the anemometer 11 on the hangar 1 through the fixing bracket 211. At this time, the hangar 1 can power the three-axis gimbal 22 and the components set on the installation box 23 through the base 21. The three-axis gimbal 22 can pitch from -15° to +75° and rotate 360° horizontally. The warning radar 213 can detect based on living organisms and set a warning circle with a diameter range of 1-12m. The gimbal camera 231 has an intelligent AI algorithm to identify key information such as personnel, vehicles, fireworks, etc., and can automatically track and lock the target. For taking photos or recording videos, the installation box 23 is provided with an SD slot so that an SD card can be inserted to save the recorded videos and photos. The fixing plate 31 is provided with a rectangular groove for avoiding the SD card slot, and sound and light warnings and expulsion of people or animals invading the warning range; the loudspeaker 212 can not only warn the onlookers, but also has a high-frequency bird-repelling function, which can be set to automatically start when taking off and landing to avoid the safety hazards caused by flying birds when the drone takes off and lands; one end of the L-shaped guide bar 311 is parallel to the top of the installation box 23, and the other end is parallel to the top of the installation box 23. The fixing plate 31 is parallel to the side of the installation box 23 close to the pan-tilt camera 231, and is located on the two side edges of the installation box 23 adjacent to the pan-tilt camera 231; under the traction of the driving mechanism 4, the plurality of protective plates 321 are located above the installation box 23. At this time, under the torsion of the horizontal torsion spring 322, the plurality of protective plates 321 are arranged in a horizontal state in sequence, and the plurality of sliding columns 312 located on the same L-shaped guide bar 311 are hinged to each other in sequence, so that the plurality of protective plates 321 can form a "blocking plane" above the installation box 23 to block sunlight and falling objects. The sundries on the installation box 23 are blocked, thereby protecting the installation box 23 and the components arranged thereon and prolonging the service life; and through the arrangement of multiple protective plates 321, when the protective plates 321 are damaged, they can be relatively independently disassembled and maintained, thereby improving maintenance efficiency and reducing maintenance costs; secondly, when a heavy object falls onto the protective plate 321, the horizontal torsion spring 322 can give the protective plate 321 a certain "elastic force", thereby avoiding the rigid collision between the protective plate 321 and the heavy object, and can play a certain protective role on the protective plate 321;When it is necessary to clean the pan-tilt camera 231, under the action of the driving mechanism 4, multiple sliding columns 312 on the two fixing plates 31 move synchronously, so that multiple protective plates 321 can move to the position of the pan-tilt camera 231. At this time, with the cooperation of the adjusting mechanism 6, the protective plate 321 that moves to the position of the pan-tilt camera 231 can rotate along the axis of the corresponding rotating shaft 32, so that the opening direction of the strip-shaped groove 3211 on the protective plate 321 faces the pan-tilt camera 231. Subsequently, the U-shaped plate 51 located in the strip-shaped groove 3211 can move along the strip-shaped groove 3211 towards its opening direction, so that the sponge sleeve 521 provided on the cleaning roller 52 can contact the surface of the pan-tilt camera 231. At this time, the cleaning roller 52 can rotate as the protective plate 321 moves, so that multiple sponge sleeves 521 can sequentially clean the surface of the pan-tilt camera 231, improving the cleaning effect and ensuring the clarity of the pan-tilt camera 231; and multiple protective plates 321 are arranged horizontally when they move to the position of the pan-tilt camera 231, so that there is a certain shooting gap between multiple protective plates 321, thus avoiding blocking the pan-tilt camera 231 and enabling the pan-tilt camera 231 to continue to be used during the cleaning process, ensuring the safety of the hangar 1.;

[0039] See Figure 6 and Fig.10 As shown, two sector-shaped covers 3212 for blocking the strip-shaped groove 3211 are hinged to the side of each protective plate 321 away from the corresponding rotating shaft 32.

[0040] In order to ensure that the rotating shaft 32 can rotate, there is a certain gap between the protective plate 321 and the rotating shaft 32. This will cause sunlight or small dust and impurities to fall onto the mounting box 23, thereby affecting the service life of the overall device. Therefore, in order to further improve the protection effect, two sector-shaped covers 3212 are provided on the protective plate 321. The sector-shaped covers 3212 are hinged to the corresponding ends of the protective plate 321 through spring hinges, so that the two sector-shaped covers 3212 can fit together to form a semi-circular shape and contact the adjacent rotating shaft 32. When multiple protective plates 321 are located above the mounting box 23, the adjacent protective plates 321 can fit together, thereby improving the overall protection effect. Secondly, when the cleaning roller 52 extends out of the strip-shaped groove 3211, the sector-shaped cover 3212 can contact the sponge sleeve 521 on the cleaning roller 52 under the action of the spring hinge. As the cleaning roller 52 rotates, the rainwater and dust remaining on the sponge sleeve 521 are cleaned, improving the service life of the sponge sleeve 521 and ensuring the subsequent cleaning effect of the sponge sleeve 521. And when the U-shaped plate 51 retracts into the strip-shaped groove 3211, the sector-shaped cover 3212 can block the strip-shaped groove 3211, thereby preventing the sponge sleeve 521 from being contaminated when not in use and ensuring the subsequent cleaning effect of the pan-tilt camera 231.

[0041] See Figures 4 to 7 As shown, the driving mechanism 4 includes a driving shaft 41 and a traction rope 42. The driving shaft 41 is rotatably arranged between two fixing plates 31 and is located on the side of the top of the mounting box 23 away from the pan-tilt camera 231. Two winding wheels 411 are equidistantly arranged on the driving shaft 41. A traction rope 42 is arranged on each sliding column 312 close to the driving shaft 41. One end of each traction rope 42 away from the corresponding sliding column 312 is wound around the corresponding winding wheel 411. A guide plate 313 is further arranged on each fixing plate 31. The guide plate 313 is located between the driving shaft 41 and the corresponding L-shaped guide bar 311. A guiding hole 3131 for the traction rope 42 to pass through is further arranged on each guide plate 313. The traction rope 42 passes through the corresponding guiding hole 3131. A pushing spring 421 is sleeved on each traction rope 42. The pushing spring 421 is located between the corresponding guide plate 313 and the sliding column 312.

[0042] The cam 321 is provided with an adjusting motor for rotating the drive shaft 41, and when the installation box 23 needs to be protected, the drive shaft 41 is driven to rotate by the adjusting motor, and the drive shaft 41 reels the traction rope 42 through the reel 411, so that the multiple sliding columns 312 on the two fixed plates 31 can be synchronously moved toward the direction close to the drive shaft 41, so that the multiple protection plates 321 can be moved to the top of the installation box 23, thereby protecting the installation box 23; when the gimbal camera 231 needs to be cleaned, the traction rope 42 is loosened by the adjusting motor, and under the action of the elastic force of the push spring 421, the multiple rotating shafts 32 can be synchronously moved toward the direction away from the drive shaft 41, and at this time, the protection plate 321 rotates, so that the sponge cover 521 set in the strip groove 3211 can contact the gimbal camera 231, so that the gimbal camera 231 is cleaned multiple times, thereby ensuring the clarity of the gimbal camera 231.

[0043] See also Figure 3 As shown, a fill light 232 is also provided on the top of one side of the installation box 23 close to the pan-tilt camera 231 .

[0044] By providing the fill light 232 , not only can the corresponding light source be provided for the pan-tilt camera 231 when light is insufficient, but also the pan-tilt camera 231 can capture the dynamics and warn of nearby human or animal activities.

[0045] See also Figures 4 to 8 As shown, the adjustment mechanism 6 includes an arc-shaped guide bar 61; there are two arc-shaped guide bars 61, which are mirror-imaged on opposite sides of the corresponding fixed plate 31 and located on the side of the mounting box 23 close to the pan-tilt camera 231, and each arc-shaped guide bar 61 is provided with an arc-shaped avoidance groove 62 for avoiding the sliding column 312; the outer walls at both ends of each rotating shaft 32 are provided with L-shaped guide columns 323 that cooperate with the arc-shaped guide bar 61.

[0046] As the sliding column 312 moves, the sliding column 312 moves into the arc-shaped avoidance groove 62 of the arc-shaped guide strip 61. At this time, the L-shaped guide column 323 arranged on the rotating shaft 32 can contact the corresponding arc-shaped guide strip 61, so that the protective plate 321 is flipped over, so that the sponge sleeve 521 located in the strip groove 3211 can clean the fill light 232 and the gimbal camera 231, avoiding the light source from being contaminated while ensuring the shooting accuracy of the gimbal camera 231.

[0047] See also Figures 8 to 10As shown, the cleaning mechanism 5 further includes a friction wheel 53 and a guide post 54; at both ends of each cleaning roller 52, it extends out of the corresponding U-shaped plate 51 and is provided with a friction wheel 53. Inside both sides of each strip-shaped groove 3211, there is a strip-shaped avoidance groove 3213 for avoiding the cleaning roller 52. On the opposite sides of the two fixing plates 31, there are arc-shaped friction strips 314 that cooperate with the friction wheel 53; there are multiple guide posts 54, and the guide posts 54 are equidistantly arranged on the inner wall of the bottom of the corresponding strip-shaped groove 3211; on each U-shaped plate 51, there are multiple guide holes 511, and the guide posts 54 are slidably arranged in the corresponding guide holes 511. At the end of each guide post 54, there is a limit disk 541, and the limit disk 541 is located between the U-shaped plate 51 and the cleaning roller 52; on each guide post 54, there is also a retracting spring 542, and the retracting spring 542 is located between the limit disk 541 and the U-shaped plate 51.

[0048] When the protective plate 321 is above the mounting box 23, under the elastic force of the retracting spring 542, the U-shaped plate 51 can be retracted into the corresponding strip-shaped groove 3211, so that the sector-shaped cover 3212 can block the opening of the strip-shaped groove 3211; when multiple sliding columns 312 move along the L-shaped guide bar 311, the friction wheel 53 provided at the end of the cleaning roller 52 can contact the arc-shaped friction strip 314 on the fixing plate 31, so that while the friction wheel 53 rotates, it moves towards the direction close to the opening of the corresponding strip-shaped groove 3211, so that the U-shaped plate 51 extends out of the strip-shaped groove 3211, thus separating the two sector-shaped covers 3212, so that the sponge sleeve 521 on the cleaning roller 52 can clean the dust on the pan-tilt camera 231 and the fill light 232. And during the cleaning process, the cleaning roller 52 rotates self-driven under the cooperation of the friction wheel 53, which can not only improve the cleaning effect of the sponge sleeve 521, but also make the dust and impurities adhered to the sponge sleeve 521 contact the sector-shaped cover 3212, so as to clean the residual dust and impurities on the sponge sleeve 521 and ensure the subsequent cleaning effect.

[0049] See Figures 1 to 3 As shown, on the two side faces of the mounting box 23 adjacent to the pan-tilt camera 231, there are also atmosphere lights 233, and on each fixing plate 31, there is a circular hole 315 for avoiding the atmosphere lights 233.

[0050] By providing the atmosphere lights 233, the reminder range of the lights can be further improved, and the usage requirements in different scenarios can be met.

[0051] See Figures 2 to 3 As shown, at one edge along the length direction of the top of the mounting box 23, there is a laser module 234.

[0052] Since the location of hangar 1 is relatively remote, by providing a laser module 234, when the staff needs to maintain the equipment, the laser module 234 emits a laser into the sky, thereby facilitating the staff to find hangar 1 for corresponding maintenance work.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
