A Dual Spectrum Camera Applied in Alpine Region

Abstract

The invention discloses a dual-spectrum camera used in alpine regions, belonging to the field of electric power. The camera includes a casing, a hot air system located inside the casing and arranged in the lens, a hot air nozzle arranged on the surface of the lens, and a wiper; the hot air system includes a hot air channel and hot air control device; the hot air control device is located inside the hot air channel; the hot air control device includes a preheating control unit, a fan control unit and a heating control unit; the preheating control unit heats the air at the wide end to obtain preheated air; the fan control The unit pushes preheated air or external air to the tail of the narrow end; the heating control unit reheats the air at the tail of the narrow end; the outer layer of the camera shell and the hot air channel are all made of carbon fiber; The problem that spectral cameras cannot be used in winter in alpine regions can be widely used in substations in alpine regions, eliminating hidden dangers in the operation of substations and reducing the risk of electricity consumption in northern my country.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a dual-spectrum camera applied in alpine regions. Background technique [0002] The casing of the existing dual-spectrum camera is made of plastic or aluminum alloy. The dual-spectrum camera based on these two materials is suitable for the ambient temperature of -30°C to 60°C. No matter how low the temperature is, some problems will appear. [0003] If the shell is made of plastic, it will affect the monitoring accuracy of the dual-spectrum mid-infrared spectrum, because the thermal conductivity of the plastic shell is relatively low, and the heat cannot be dissipated. Overheating will greatly reduce the accuracy of the infrared spectrum lens and affect the monitoring quality. With the rapid development of infrared spectrum camera technology, the monitoring accuracy of infrared spectrum cameras is gradually improving, but there is also a problem, that is, a large amount of heat need...

Problems solved by technology

However, because aluminum alloy materials have thermal expansion and contraction problems, if they are used in low-latitude regions of my country, winter is not very cold, so the degree of thermal expansion and contraction of aluminum alloys is not very obvious, and in alpine regions, the lowest temperature can reach -50 ℃, the aluminum alloy material will undergo obvious deformation, and the aluminum alloy shell cannot be stamped and formed at one time, and multiple pieces must be riveted or welded, so the deformation will cause cracks, which will reduce the protection level, which will easily lead to corrosion of the circuit board and affect camera stability
