Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0028] See Figure 1 、 Figure 2 and Figure 3 A protective security surveillance camera shown includes a pan-tilt camera 1 and a controller 2. The pan-tilt camera 1 is connected to the controller 2. The controller 2 has a built-in storage unit. The controller 2 is connected to the control room via a wireless network or a wired network to facilitate reading of video files stored in the pan-tilt camera 1 and adjusting the shooting angle of the pan-tilt camera 1 through the controller 2. It also includes a box structure 3 and an axis device 4 installed through the box structure 3. The axis device 4 is rotatably engaged with a translucent ball cover 5. The pan-tilt camera 1 is installed through the axis device 4 and is located in the translucent ball cover 5. A cleaning device 6 is installed through the axis device 4. The cleaning device 6 cleans the outer surface of the translucent ball cover 5.

[0029] In the above technical solution, the PTZ camera 1 is installed inside the transparent ball cover 5, and the interior of the transparent ball cover 5 is sealed, which provides dust protection for the PTZ camera 1 and ensures that the clarity at the lens position of the PTZ camera 1 always remains optimal.

[0030] In the above technical solution, the surface cleaning of the transparent ball cover 5 is completed by actively rotating the transparent ball cover 5 to contact the cleaning device 6, ensuring that the transmittance of the transparent ball cover 5 is always greater than 95%, ensuring that the pan-tilt camera 1 has a sufficiently clear shooting field of view.

[0031] See Figure 3 and Figure 4 As shown, the shaft device 4 includes a fixed shaft 41 and a water-cooling pipe 42, the fixed shaft 41 is fixed to the box structure 3, and the transparent ball cover 5 is rotatably connected to the fixed shaft 41 and the water-cooling pipe 42 respectively, one end of the water-cooling pipe 42 is installed with the cleaning device 6, and the other end is connected to the fixed shaft 41, and the end of the water-cooling pipe 42 away from the cleaning device 6 is provided with a water inlet pipe 43, and the water inlet pipe 43 axially penetrates the water-cooling pipe 42 and then passes through the side of the box structure 3, and a plug 44 is provided at the end of the fixed shaft 41, and the water inlet pipe 43 passes through the plug 44, and a wiring gap is formed between the water inlet pipe 43 and the fixed shaft 41, and a bracket 45 is provided on the fixed shaft 41, and the pan-tilt camera 1 is installed through the bracket 45, and the wiring harness between the pan-tilt camera 1 and the controller 2 passes through the wiring gap and passes through the side wall of the fixed shaft 41.

[0032] In the above technical solution, the fixed connection between the fixed shaft 41 and the water cooling pipe 22 is used as a support to complete the rotational installation of the light-transmitting ball cover 5. Water is supplied to the cleaning device 6 through the water cooling pipe 42 to clean the surface of the light-transmitting dome cover 5 with water.

[0033] The end of the water inlet pipe 43 is connected to a water pump, and water is supplied by the water pump.

[0034] The water pumps are controlled independently or remotely via controller 2.

[0035] See Figure 2 、 Figure 4 and Figure 5 As shown, a support rod 451 is provided on the upper part of the bracket 45, and a light-shielding ball screen 452 is supported by the support rod 451. The light-shielding ball screen 452 is consistent with the spherical shape of the transparent ball cover 5, and the light-shielding ball screen 452 covers the top of the pan-tilt camera 1.

[0036] In the above technical solution, a light-shielding ball screen 452 design is adopted to reduce direct sunlight and extend the aging cycle of the pan-tilt camera 1.

[0037] See Figure 5 and Figure 6 As shown, a cleaning cotton layer 453 is laid on the top of the light-shielding ball curtain 452 . As the light-shielding ball curtain 452 rotates, the cleaning cotton layer 453 cleans the inner wall of the light-shielding ball curtain 452 .

[0038] In the above technical solution, the primary function of the cleaning cotton layer 453 is to clean the inner wall of the light-transmitting ball cover 5. When there is a temperature difference between the inside and the outside, water mist may be generated on the inner wall of the light-transmitting ball cover 5. At this time, through the rotation of the light-transmitting ball cover 5, the cleaning cotton layer 453 is used to clean the inner wall of the light-transmitting ball cover 5, ensuring a clear field of view.

[0039] Secondly, the cleaning cotton layer 453 can play a role in top heat insulation, thereby alleviating the internal temperature rise of the light-transmitting ball cover 5 .

[0040] See Figure 3 and Figure 7 As shown, the box structure 3 includes a box body 31, a box cover 32 and a drive motor 310. The box cover 32 is detachably mounted on the top of the box body 31. An inner bracket 33 is provided inside the box body 31. The fixed shaft 41 is fixedly mounted through the inner bracket 33. The box body 31 has a shaft tube 34. The fixed shaft 41 is coaxial with the shaft tube 34. A rotating portion 51 is provided at the ball diameter of the light-transmitting ball cover 5. The rotating portion 51 is clearance-matched with the shaft tube 34. The rotating portion 51 is respectively fitted with the fixed shaft 41 and the water-cooling tube 42. The shaft seal 53 is sealed on the outside of the bearing 52. A first sealing ring 35 is clamped on the inner wall of the shaft tube 34. The first sealing ring 35 forms a seal with the rotating part 51. A driven gear 54 is coaxially arranged on the outside of the rotating part 51 at one end. The drive motor 310 is fixed in the box body 31. The output end of the drive motor 310 is equipped with a driving gear 311 that drives the driven gear 54 to rotate. The end of the box body 31 away from the light-transmitting ball cover 5 is provided with a connecting bracket 355 for connecting to the wall.

[0041] In the above technical solution, the box body 31 and the box cover 32 are of detachable structure, which is convenient for assembly and maintenance, and the light-transmitting ball cover 5 is supported by the bearing 52 for rotation.

[0042] The first sealing ring 35 ensures sealing and reduces the intrusion of dust into the box body 31 .

[0043] The driving motor 310 is controlled by the controller 2 , and the working cycle of the driving motor 310 is remotely set through the main control room.

[0044] See Figure 3As shown, part of the water inlet pipe 43 is exposed in the box body 31, and a heat exchange plate 431 is provided at the part of the water inlet pipe 43 exposed in the box body 31; an air inlet pipe 36 is provided at the bottom of the box body 31, and an air filter element 37 is detachably installed at the pipe mouth of the air inlet pipe 36, and an air outlet pipe 38 is provided at an angle downward on the inner wall of the box body 31, and the air outlet pipe 38 is located above the heat exchange plate 431. A cooling fan 39 is installed at the pipe mouth of the air outlet pipe 38. After the cooling fan 39 is started, the heat in the box body 31 is discharged to the outside through the air outlet pipe 38.

[0045] In the above technical solution, the high temperature inside the box 31 is absorbed by the heat exchange plate 431, and the heat is exhausted by the cooling fan 39 to take out the heat in the box 31, thereby avoiding the high temperature of the drive motor and the controller 2.

[0046] See Figure 4 As shown, a first heat exchange fin 421 is provided at the portion of the water cooling pipe 42 located at the light-transmitting dome cover 5 .

[0047] The first heat exchange plate 421 can absorb the accumulated heat in the light-transmitting dome cover 5 . Compared with the traditional air-cooling heat dissipation, this method does not ventilate the interior of the light-transmitting dome cover 5 , thus preventing dust particles from entering.

[0048] See Figure 4 and Figure 7As shown, the cleaning device 6 includes a cleaning portion 61 and a sliding shaft 62. An inner tube 63 is installed on the inner side of the nozzle of the water-cooling tube 42. The inner tube 63 is fixed to the water-cooling tube 42. A water cavity 64 is formed between the inner tube 63 and the water-cooling tube 42. A water inlet 65 and a water outlet 66 are provided on the tube wall of the inner tube 63. A pipe cap 67 is threadedly fitted on the inner tube 63. A second sealing ring 68 is provided at the contact position between the pipe cap 67 and the inner tube 63 and the water-cooling tube 42. The sliding shaft 62 is coaxial with the pipe cap 67. A sealing ring 69 is clamped on the inner wall of the pipe cap 67. The ring 69 contacts the sliding shaft 62 to form a seal. The sliding shaft 62 is a hollow shaft. After the sliding shaft 62 passes through the pipe cap 67, it is equipped with a piston 610. A sealing ring 611 is provided on the outer wall of the piston 610. The outer wall of the sliding shaft 62 is provided with a first water inlet 612 at a position close to the piston 610. A spring 613 is provided on the outside of the sliding shaft 62. The spring 613 is located between the pipe cap 67 and the piston 610. When the spring 613 is in a relaxed state, the piston 610 and the sealing ring 611 cooperate to block the water inlet 65. As the water pressure in the water-cooling pipe 42 gradually increases, the piston 610 compresses the spring 613 until the water inlet hole 65 is exposed to the right side of the piston 610. At this time, the cold water in the water-cooling pipe 42 enters through the water inlet hole 65, flows out from the water outlet hole 66, and finally flows into the sliding shaft 62 from the first water inlet hole 612. When the water pressure is insufficient, the spring 613 resets and the water inlet hole 65 is closed; the end of the sliding shaft 62 away from the piston 610 is provided with a connecting pipe 633, and the outer wall of the connecting pipe 633 is provided with a water outlet groove 614, and the cleaning part 61 is detachable. It is assembled on the connecting pipe 633, and the water discharged from the water outlet trough 614 is sprayed onto the surface of the translucent ball cover 5 after passing through the cleaning part 61; a mounting plate 442 is provided at the position where the water-cooling pipe 42 is exposed to the outer wall of the translucent ball cover 5, and a guide rod 443 is installed through the mounting plate 442, and the guide rod 443 is parallel to the water-cooling pipe 42, and a first mounting plate 662 is provided on the outer wall of the sliding shaft 62, and the first mounting plate 662 has a guide sleeve 663 that cooperates with the guide rod 443, and the first mounting plate 662 forms a limit for the inward sliding of the sliding shaft 62.

[0049] In the above technical solution, the sliding shaft 62 can slide along the axial direction of the water-cooling pipe 42. When the water pump pumps water toward the water-cooling pipe 42, the water pressure in the water-cooling pipe 42 increases, and the water pressure pushes the piston 610 to compress the spring 613 until the water inlet hole 65 is exposed. At this time, the water pumping pressure is maintained, so that water passes through the water inlet hole 65 and flows out from the water outlet hole 66 and then passes through the sliding shaft 42 to supply the cleaning part 61. At this time, the cleaning part 61 is separated from the light-transmitting ball cover 5, and the water mist increases the contact area with the light-transmitting ball cover 5 after dispersion. During the above operation process, the light-transmitting ball cover 5 keeps rotating to complete the water washing and cleaning of the surface of the light-transmitting ball cover 5.

[0050] See Figure 7 、 Figure 8 and Figure 9 As shown, the cleaning portion 61 includes a connecting portion 6610 and an arcuate portion 6611. The connecting portion 6611 is sleeved on the connecting pipe 633. A third sealing ring 6614 is clamped on both sides of the connecting portion 6611. A nut 6665 for fixing the connecting portion 6610 is installed through the connecting pipe 633. The lower surface of the arcuate portion 6611 is provided with an arcuate concave surface 6615. A wiper strip 6616 is provided at the middle position of the concave surface 6615. The concave surface 6615 is located at the wiper strip 6616. Nozzles 6617 are arranged on both sides of 616, and bristles 6618 are provided on both sides of the concave surface 6615 below the arc portion 6611. When the spring 6613 is not compressed, the bristles 6618 act on the outer spherical surface of the light-transmitting ball cover 5. When the water pressure in the water-cooling tube 42 pushes the piston 610, the spring 613 is compressed synchronously. At this time, the arc portion 611 gradually moves away from the light-transmitting ball cover 5, and water is sprayed from the nozzle 6617, and the nozzle 6617 is directed towards the bristles 6618.

[0051] In the above technical solution, the water input from the water-cooling pipe 42 flows into the arc-shaped part 6611 after passing through the connecting part 6610. The nozzle 6617 adopts an atomizing nozzle. The water is pressurized and sprayed out from the nozzle 6617. During the spraying process, the nozzle 6617 is away from the light-transmitting ball cover 5, and the nozzle 6617 is directed towards the bristles 6618. After the water mist is sprayed out, it first wets the bristles 6618 and then acts on the surface of the light-transmitting ball cover 5. The advantage of doing this is that the water mist will clean the bristles 6618 to ensure the cleanliness of the bristles 6618. Secondly, the distance between the nozzle 6617 and the water mist will make the dispersion area of ​​​​the water mist larger and more effectively adhere to the surface of the light-transmitting ball cover 5.

[0052] In the above technical solution, a wiper strip 6616 is also provided, and the water spraying direction of the nozzle 6617 is away from the wiper strip 6616, so that the water mist can fully contact the bristles 6618 and the transparent ball cover 5 before being scraped off by the wiper strip 6616.

[0053] The provision of the wiper strip 6616 can scrape off water droplets adhering to the surface of the light-transmitting dome cover 5, thereby avoiding the situation where the image cannot be clearly photographed due to refraction.

[0054] The wiper strip 6616 can also play a supporting role, preventing the bristles 6618 from excessively contacting the light-transmitting ball cover 5.

[0055] See Figure 9 As shown, two forked scraping portions 6666 are provided below the wiper strip 6616. When the spring 613 is reset, the forked scraping portions 6666 contact the surface of the light-transmitting spherical cover 5 and are compressed. At this time, supported by the forked scraping portions 6666 on both sides, the nozzle 617 is separated from the surface of the light-transmitting spherical cover 5.

[0056] The bifurcated scraping portion 6666 can increase the scraping efficiency during the rotation of the light-transmitting dome cover 5 and can also provide a certain supporting effect.
