Embodiment 1
[0034] see Figure 1-4 , Image 6 , In the embodiment of the present invention, a laser night vision surveillance camera with a protective device includes a casing 1, a lens 2, a high-definition lens 201, an infrared lamp 202, a white light 203 and a rain cover 3. The inner position of the left and right inner walls of the casing 1 There are several protective components 4 that can prevent water vapor from infiltrating and accumulating;
[0035] Each set of protective components 4 includes a protective shell 401, a heating component 402 that can generate heat, a deflection component 403 that can deform with the entry of water vapor, and a guide component 404 that can guide the flow of hot air.
[0036] In the embodiment of the present invention, the appearance of each protective shell 401 is in the shape of a letter U with a hollow interior and an inclination of 90° on a longitudinal section, and a water vapor inlet is opened at the upper position of the right end of each pro...
Embodiment 2
[0040] see Figure 4 , Figure 6-7 The difference between the embodiment of the present invention and the embodiment 1 is that each group of heating components 402 includes a rotating shaft 4021 and a balance plate 4022 .
[0041] In the embodiment of the present invention, each rotating shaft 4021 is rotatably installed in the central position of the front and rear inner walls of each protective shell 401 in the front and rear horizontal directions, and the outer surface of each rotating shaft 4021 is surrounded and fixedly installed with a balance plate 4022. Each balance plate 4022 Under normal conditions, they are in a horizontal static balance state. The left and right outer surfaces of each balance plate 4022 are in normal condition with the left and right inner walls of each protective shell 401. There are grooves, and each groove is pre-installed with quicklime powder 40221;
[0042] The balance plate 4022 here is to use the lever principle. After the water vapor ent...
Embodiment 3
[0045] see Figure 4-5 The difference between the embodiment of the present invention and the embodiment 1 is that each set of offset components 403 includes a metal plate 4031 , a heat insulation shell 4032 and a battery box 4033 .
[0046] In the embodiment of the present invention, a metal plate 4031 is fixedly installed on the right portion of the bottom end of each protective shell 401 , and the appearance of each metal plate 4031 is a thin plate shape with an upper concave and a flat bottom, and the material of each metal plate 4031 is the same It is made of copper, and a heat insulating shell 4032 is fixedly installed at the center of the outer surface of the bottom side of each metal plate 4031. A battery box 4033 is fixedly installed on the inner wall of the shell 4032;
[0047] The appearance of the metal plate 4031 here is set as a thin plate shape with an upper concave and a flat bottom, and the material is copper, so that the metal plate 4031 can expand after bei...
