A portable high and low temperature camera protection device

Abstract

The invention discloses a portable high and low temperature camera protection device, which includes an outer protection cabin, an inner protection cabin, an outer cooling structure, an inner heating structure, a nitrogen circulation structure, a temperature acquisition and controller, and a heating and cooling controller. In the inner protective cabin, the external cooling structure arranges the cooling plate on the outer surface of the inner protective cabin, lays the pipeline for transmitting the refrigerant liquid inside the cooling plate, and arranges the internal heating structure evenly inside the inner protective cabin. The temperature acquisition and controller are based on the current temperature and The difference of the target temperature adjusts the coolant flow rate in the external cooling structure and the heating output power in the internal heating structure through the heating and cooling controller, and finally keeps the CCD camera in the inner protection cabin at normal temperature and pressure. The invention can directly carry out the real-time video recording of the test process under normal pressure, high and low temperature environment, effectively control the condensation of low temperature water vapor, and obtain a clear product state image.

Description

technical field

[0001] The invention relates to a portable high and low temperature camera protection device, in particular to a portable normal pressure / vacuum high and low temperature camera protection device, which is suitable for all-round measurement of in-situ and real-time camera in a wide temperature range environment. Background technique

[0002] The camera protection device for the test process in the normal pressure / vacuum high and low temperature environment mainly solves the problem of accurate, real-time and clear video recording of the unfolding and folding of large structural products in the normal pressure / vacuum high and low temperature environment and the movement state and process.

[0003] Some of the existing protection devices for measuring equipment in high and low temperature environments control the temperature in the cabin by pasting heating sheets on the outer wall of the cabin, and provide a normal temperature working environment for the camera d...
