[0049] Let's talk about the working principle of the corridor security camera in the office building in detail.

[0050] like Figure 1-8 As shown, when in use, when the outer wall of the camera 2 is impacted, the lateral protective net 18 transmits the impact to the inside of the first buffer spring 19, so that it deforms and generates a reaction force to offset the impact, and the camera 2 is laterally positioned. For protection, when the upper side is impacted, it is protected by the external protective shell 3, and the first buffer composite shrapnel 16, the second buffer composite shrapnel 17 and the auxiliary spring rod 24 are used for buffer protection. When the front of the camera 2 is impacted, the front A protective net 21 is placed to protect the lens 35 , and a monitoring through hole 22 is reserved on the front protective net 21 to avoid influence on the probe in the camera 2 .

[0051] When the lens 35 needs to be cleaned, start the first micro cleaning motor 5 and the second micro cleaning motor 6, respectively drive the first cleaning brush plate 7 and the second cleaning brush plate 8 to rotate alternately for cleaning, while cleaning, turn on the electricity. The control valve sprays the cleaning water in the water inlet pipe 14 onto the lens 35 to enhance the cleaning effect.

[0052] After the cleaning is completed, start the micro air pump 4, and transfer the hot air generated by the operation of the internal components of the camera 2 extracted by the micro air pump 4 to the bristles of the bristle plate 31 through the drying double air pipe 33 to speed up drying and facilitate the next use. Start the built-in cooling fan. 9. The heat generated inside the camera 2 is transported to the outside, and at the same time, it is used in conjunction with the lateral heat dissipation fins 11 to speed up the heat dissipation efficiency and avoid the accumulation of internal heat, causing damage to the internal components of the camera 2.

[0053] When replacing the bristle plate 31 in the first cleaning brush plate 7, it is only necessary to press the pressing blocks 47 on both sides. The pressing blocks 47 move down to compress and press the return spring 48, and at the same time drive the linkage rod 49 to move down on the inner wall of the bearing groove 50. , the linkage rod 49 drives the snap block 44 to move down to release the restriction on the limit block 43, and then pulls and installs the push-pull block 45 to complete the disassembly of the bristle plate 31. The left end is docked with the installation port of the first cleaning brush plate 7 and then pressed to complete the installation.

[0054] When installing the first cleaning brush plate 7, pass 30 through the hole on the first cleaning brush plate 7, and then install its left end on the inner wall of the rotating installation cylinder 27, using the interaction between the rubber baffle ring 29 and the installation limit spring 28 Limit the position of 30 for the first time to prevent it from falling off due to improper operation during the installation process, and then rotate and rotate the installation block 30 so that the left end of the installation block 30 is threadedly connected to the inner wall of the rotating installation cylinder 27 to complete the installation.
