Description

Technical Field

[0001] The utility model relates to the field of ultra-low temperature cameras, in particular to an ultra-low temperature camera. Background Art

[0002] A camera is a device used to record images and is common in daily life.

[0003] Conventional cameras are only suitable for standard indoor and outdoor video surveillance applications, typically operating in temperatures between -20°C and 60°C. Some industrial-grade wide-temperature cameras also typically operate within a -40°C to 80°C range. However, these cameras will not function properly in extremely low-temperature environments, such as outdoor locations in extremely cold regions and cold storage facilities. Furthermore, some low-temperature cameras are only suitable for low-temperature environments and cannot be used in normal temperature environments, or in environments with large temperature fluctuations.

[0004] This invention designs a camera that can operate in both ultra-low and normal temperature environments. It features a built-in camera module, heating module, temperature detection and control switch, thermal insulation module, and fill light module. It is housed in a stainless steel housing with explosion-proof glass windows, providing a high level of explosion-proof protection. It automatically detects the operating temperature of internal equipment and activates the heating module when the temperature falls below a preset value, and automatically deactivates it when the temperature rises above the preset value, ensuring the proper functioning of the camera module and other components. It can be used for indoor and outdoor video surveillance in extremely cold environments, such as cold storage facilities.

[0005] Therefore, it is necessary to provide a new ultra-low temperature camera to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art and to provide an ultra-low temperature camera.

[0007] In order to solve the above technical problems, the utility model provides an ultra-low temperature camera, comprising: a base, two fixing screws are installed on the inner wall of the base, a shell is installed on the end where the two fixing screws are close to each other, a front cover is installed on the inner wall of the shell, a rear cover is installed on the end of the shell away from the front cover, a wire outlet hole is opened on the inner wall of the rear cover, a wire outlet pipe is fixedly connected to the side of the rear cover away from the front cover, a power board, a main board and a function board are respectively installed inside the shell, the power board, main board and function board are connected to the front cover, a lens is installed inside the front cover, several fill lights are installed inside the front cover, a temperature control switch is installed inside the shell, a heating plate is installed inside the shell, and heat insulation cotton is fixedly connected to the arc surface of the shell, a glass window is installed on the end of the shell close to the front cover, a glass body is installed inside the glass window, and a rubber ring is installed between the glass body and the glass window.

[0008] The effects achieved by the above components are as follows: the lens is installed on the main board, and the fill light is connected to the main board via a cable. The function board is used for storage, wireless transmission, etc., and the power board supplies power to the internal components. The heating unit usually uses a heating plate, which is generally designed with two, distributed on both sides of the main unit, close to the thermal insulation layer of the camera casing. The temperature control unit generally uses an integrated temperature control switch, that is, temperature detection and switch control are integrated, connected in series with the heating unit, and installed on the rear of the main unit. The temperature control switch senses the temperature in real time. When the temperature is lower than the preset value, the switch is closed and the heating unit works. When the temperature is higher than the preset value, the switch is disconnected and the heating unit stops working, so that the components inside the camera are always within the normal operating temperature range.

[0009] Preferably, the heating sheet is a heating strip, and the surface of the heating sheet is wrapped with an external material, and the external material is a ceramic sheet.

[0010] Preferably, the heating sheet is a heating ring, and the outer material is a silicone sheet.

[0011] Preferably, the temperature-controlled switch is a component that integrates temperature detection and switch control.

[0012] Preferably, a heat insulation layer is provided inside the shell, and the heat insulation layer is a heat insulation board.

[0013] Preferably, the thermal insulation layer is a thermal insulation tile.

[0014] Preferably, the shell is a stainless steel shell.

[0015] Preferably, the shell is an aluminum alloy shell.

[0016] Compared with related technologies, the ultra-low temperature camera provided by the present invention has the following beneficial effects:

[0017] The utility model provides an ultra-low temperature camera. By setting up an overall structure, it can be used for a long time in ultra-low temperature environments such as -70°C. It has a built-in intelligent temperature control unit to prevent the heating unit from working for a long time, which is energy-saving and environmentally friendly, and can also be used in normal temperature environments. At the same time, it is provided with a heat insulation layer, which can not only slow down the external low temperature from entering the interior of the camera, but also prevent the internal high temperature of the camera from being transmitted to the outside and affecting the low temperature environment in which the camera is located. The stainless steel shell has a high protection and explosion-proof grade and can be used for video surveillance in ultra-low temperature areas and dangerous areas, such as extremely cold regions, cold storage, petrochemical crude oil tank areas, chemical plant areas, etc. BRIEF DESCRIPTION OF THE DRAWINGS
