The traditional design of the shield machine is not provided with a soil bin monitoring device, the method for checking the cutter head cutter and the cutter head structure, the existence of the mud cake phenomenon and the analysis of the geological condition all need the shield machine to be shut down and opened, and the working personnel enter the front or the rear of the cutter head.

The other prior art is that a visual device is arranged in front of a cutter head, the environment is severe, the visual device is easy to damage, the observation effect is poor, and the construction requirements cannot be met.

Disclosure of Invention

The utility model aims at providing a shield constructs machine cutter head soil storehouse monitoring device solves the potential safety hazard that the staff does not know the inside condition entering existence to satisfy the construction requirement.

The technical scheme of the utility model is that: a monitoring device for a cutter head soil bin of a shield machine is characterized by comprising organic prism glass, a barrel, a panoramic fisheye network camera, a rear cover plate, a high-pressure cleaning pipe and a signal wire, wherein the organic prism glass and the rear cover plate are respectively and hermetically arranged at the front end and the rear end of the barrel; the front end of the cylinder is provided with a high-pressure cleaning pipe, and the outlet of the high-pressure cleaning pipe faces the outer side of the organic prism glass.

The utility model has the advantages that: the novel safety shield is installed on a front shield for measurement, comprehensive observation can be achieved, high-definition infrared night vision is achieved, water and automatic cleaning can be achieved, geological conditions, abrasion of a cutter and changes of a cutter head structure can be found in time, mud cakes exist or not, then inspection and maintenance are carried out, serious damage to the cutter head can be avoided, and serious safety accidents are avoided. Meanwhile, a basis can be provided for adjusting the excavation parameters of the shield tunneling machine by observing the condition of the muck in the construction process, so that the shield tunneling efficiency can be improved, and the construction cost can be reduced; and monitoring is carried out when the personnel change the cutter, so that the safety of the personnel is ensured. The shield machine is suitable for the geology not single excavation engineering, and the shield machine faces various geology along the tunnel, because this shield machine is equipped with soft soil scraper and hard rock hobbing cutter simultaneously, can in time discover the change of geology situation, the wearing and tearing of cutter and blade disc structure through observing visual device, has or not to knot mud cake phenomenon, and then inspects and maintains, avoids causing serious incident.
