Visual portable helium leak detection equipment

The embodiment of the utility model discloses visual portable helium leak detection equipment, in which a light source is arranged above a spectrograph and is used for providing a radiation source for the helium leak detection equipment; the spectrograph is used for separating the electromagnetic radiation reflected by the aerostat to be detected into a specified wavelength through a dispersion element of the spectrograph, and projecting the separated specified wavelength to the area-array camera; the area-array camera collects spectral image information of the scene image; the computer controls the operation of each device in the helium leak detection equipment, and processes the spectral image information collected by the area-array camera, thereby forming a real-time hyperspectral image of the detected aerostat. According to the utility model, the problems that potential safety hazards exist in the leakage detection process due to the fact that the device needs to be close to the surface of a sphere of an
