Alternatively, the heat dissipation member 42 may adopt a fin type heat dissipation structure or the like, so as to increase the surface area of the heat dissipation member 42 to improve the heat dissipation efficiency of the heat dissipation member 42, thereby improving the heat dissipation effect.

In an embodiment, considering that the camera of the present embodiment operates in a high temperature environment (for example, above 60 ℃), the temperature of the external environment may affect the normal operation of the camera, and may also easily cause the aging and the failure of the camera, the heat insulation assembly 60 is disposed between the outer shell assembly 12 and the inner shell assembly 13, and specifically, the heat insulation assembly 60 is disposed between the inner shell body 131 and the outer shell body 121 and/or between the inner shell upper cover 132 and the outer shell upper cover 122.

This embodiment hinders the heat transfer between outer shell subassembly 12 and the interior shell subassembly 13 through thermal-insulated subassembly 60, hinders the heat transfer of external high temperature environment and camera inner space promptly for inside being in suitable temperature range all the time of camera, guarantee that the camera still can be stable, reliable work in high temperature environment.

Specifically, inner housing assembly 13 has a first side 133 and a second side 134 oppositely disposed in a first direction (indicated by arrow Z in fig. 1, the same below) and a third side 135 and a fourth side 136 oppositely disposed in a second direction (indicated by arrow Y in fig. 1, the same below), wherein the first direction is perpendicular to the second direction, and the first direction and the second direction are both perpendicular to the predetermined direction.

Please refer to fig. 1. When the camera is properly positioned, first side 133 and second side 134 may correspond to the top and bottom of inner housing assembly 13, e.g., first side 133 is positioned at the top of inner housing assembly 13 and second side 134 is positioned at the bottom of inner housing assembly 13; the third side 135 and the fourth side 136 may correspond to the left and right sides of the inner housing assembly 13, for example, the third side 135 is located at the left side of the inner housing assembly 13, and the fourth side 136 is located at the right side of the inner housing assembly 13.

At least one of the first side 133, the second side 134, the third side 135, and the fourth side 136 is positioned with the thermal insulation assembly 60. Preferably, the heat insulation assemblies 60 are disposed at the positions of the first side 133, the second side 134, the third side 135 and the fourth side 136, as shown in fig. 1, so as to maximally obstruct heat transfer between the outer housing assembly 12 and the inner housing assembly 13, that is, maximally obstruct heat transfer between the external high-temperature environment and the internal space of the camera, and even achieve the effect of blocking heat transfer, further, the interior of the camera is always in a proper temperature range, and the camera can still stably and reliably operate in the high-temperature environment.

Further, since the outer housing component 12 and the inner housing component 13 inevitably need to be assembled together to ensure the relative fixation between the outer housing component 12 and the inner housing component 13, at least one of the first side 133, the second side 134, the third side 135 and the fourth side 136 is a target side, and the target side of the inner housing component 13 is assembled and connected with the outer housing component 12, for example, by a fastener such as a screw.

The insulation assembly 60 includes a first insulation 61 and a second insulation 62. The elasticity of the first thermal insulation member 61 is inferior to that of the second thermal insulation member 62, meaning that under the same external force, the first thermal insulation member 61 has a smaller amount of deformation than the second thermal insulation member 62, and therefore the amount of deformation of the first thermal insulation member 61 is controllable, and the assembly accuracy can be ensured. In view of this, the target side of the present embodiment is provided with the first insulator 61, and the other sides except the target side are provided with the second insulator 62, so that the assembly accuracy between the outer case assembly 12 and the inner case assembly 13 is ensured by the first insulator 61.

Alternatively, the first insulating member 61 may be an insulating plastic sheet or the like, and the second insulating member 62 may be an insulating foam or the like. Although the second heat insulator 62 is not favorable for ensuring the assembling accuracy, the heat insulating performance of the second heat insulator 62 is superior to that of the first heat insulator 61. Therefore, in the present embodiment, one of the first side 133, the second side 134, the third side 135 and the fourth side 136 is preferably used as a target side, which not only ensures the assembly between the outer casing assembly 12 and the inner casing assembly 13, but also ensures that the second heat insulation member 62 with better heat insulation performance is arranged as much as possible, so as to improve the heat insulation effect to the maximum extent. Fig. 1 shows that the second side 134 is the target side, i.e., the bottom of the inner housing component 13 is used for assembly connection with the outer housing component 12, and thus the second thermal insulation members 62 are disposed on the first side 133, the third side 135 and the fourth side 136 except for the second side 134.

In an exemplary embodiment of the utility model, as shown in fig. 1, the portion of the second side 134 between the inner housing assembly 13 and the outer housing assembly 12 is not used for assembly, i.e., the inner housing assembly 13 and the outer housing assembly 12 are not in direct contact at this location, and therefore the second thermal shield 62 is also provided at this location to further improve the thermal insulation effect.

In one embodiment, the camera further includes a window 70, the window 70 being disposed on a side of the lens assembly 20 facing away from the control assembly 30, the lens assembly 20 capturing the captured image through the window 70. Specifically, the window 70 is provided in the outer casing front cover 123 described in the above embodiments, but the window 70 and the outer casing front cover 123 may be hermetically connected by silicone or glue.

Considering that the camera of the present embodiment is applied to monitor scenes of objects such as molten iron, furnace flame, slag, etc., and has strong light radiation, which easily causes the monitoring picture of the camera to turn white, and is difficult to capture and shoot effective pictures, the light transmittance of the window element 70 of the present embodiment is set to 20% to 40%, for example, 20% to 28%, etc., so that the light intensity of the radiation light is attenuated by the window element 70 to ensure that the camera can capture and shoot effective pictures.

Further, the window 70 may be brown glass or the like, and is not limited thereto. Of course, when the camera of the present embodiment is applied to a normal scene, the window 70 may also be made of ordinary glass or the like, and is not limited herein.

In an embodiment, the camera further includes a fill-in light 80, and the fill-in light 80 is disposed outside the housing assembly 10 and below the lens assembly 20. The light supplement lamp 80 is electrically connected with the control assembly 30, and the control assembly 30 is used for controlling the light supplement lamp 80 to work. The detailed operation and principle of the fill light 80 are understood by those skilled in the art and will not be described herein.

In the case that the camera of the present embodiment is installed outdoors, the sunshade cover 15 functions as a sunshade, and can prevent direct sunlight from affecting the shooting effect of the lens assembly 20.

In summary, the camera provided by the utility model dissipates heat through the semiconductor refrigeration component, so that the camera can realize the heat dissipation function by itself without depending on external conditions. In addition, a flow guide fan is arranged between the control component and the semiconductor refrigeration component of the camera, an air inlet of the flow guide fan faces the semiconductor refrigeration component, an air outlet faces the control component, namely hot air from the lens component and the control component enters the flow guide fan after being refrigerated by the semiconductor refrigeration component, the flow guide fan outputs cold air obtained by refrigeration to the control component and the lens component again, and the flow guide fan can circularly provide the cold air for the control component and the lens component, so that the heat dissipation effect of the camera is improved, and the camera can still stably and reliably work in a high-temperature environment.
