The particle size distribution statistics of the rock slag generated in the tunneling process has certain practical significance on the tunneling condition of the TBM and the surrounding rock type evaluation. Generally, a camera is mounted on a TBM to collect and identify ballast stones so as to judge the running state of the TBM, but an industrial camera and a lens thereof are precise instruments highly sensitive to the environment, and cannot normally work or even cause damage in strong vibration, dusty and muddy environments. The TBM brings great interference to the stability of the camera and the data acquisition task under severe working conditions (such as dark light, strong vibration, much dust, mud and the like) in the tunneling operation process, the quality of acquired pictures and the long period of the service life of the camera cannot be ensured, and great challenge is brought to the ballast stone identification task.

However, the patent does not give a specific design structure of the protective cover, does not consider the contents of cleaning the detection window and slowing down the vibration influence, and is very easy to cause damage of the device and pollution of the detection window when applied to the TBM ballast stone recognition environment with much dust and strong vibration, so that the camera detection error occurs and potential safety hazard is brought by manual participation. Compared with the patent, the patent meets the protection requirement of industrial use on the whole design structure, and is internally provided with a special protection device of the camera, and the detailed design structure is given in the content. The shock absorber is designed in the whole structure to ensure stable use of the camera in a TBM construction strong vibration environment, and the detection window is cleaned in time through the circularly arranged self-cleaning nozzle device to ensure normal detection of the camera.

The utility model discloses a be CN 206573835U's an industrial camera developments protector that comprises casing, industrial camera body, driving motor and the reel device of transparent film, the casing that the camera lens is just right is equipped with the opening, accomplishes the roll change of transparent film through the synchronous rotation of two sets of reel devices, keeps the visual field clean in front of the industrial camera lens. However, in the presence of contaminants such as water, dust, mud, etc., the recovery of the transparent film is likely to cause contamination of the interior space. When the strong vibration environment of TBM used, film and reel device easily caused the damage, and the opening design that the protection set up caused the entering of pollutant easily. And the transparent film inside needs to be replaced regularly in the using process, and the problem of potential safety hazard caused by manual participation still exists. Compared with the patent, the protection device and the camera installation position have sealing performance starting from the stability of the overall design structure, and the protection device and the camera installation position comprise the shock absorber, so that the camera can be stably used in the TBM working task.
