Embodiment Construction

[0021] Embodiments of the present invention are described below through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation modes, and various modifications or changes can be made to the details in this specification based on different viewpoints and applications without departing from the spirit of the present invention.

[0022] The positions in the shield machine that are subject to high pressure, high humidity or underwater are usually in a closed state during work. For the sake of pressure resistance and sealing, these positions are not provided or only have very small observation windows. Effective visual observation or monitoring is not possible.

[0023] Based on a pressure-resistant and waterproof high-definition camera, a broadband local area n...

Abstract

The present invention discloses a pressure-and-water-resistant monitoring system in a shield tunneling machine. The system comprises a pressure-and-water-resistant camera, a video signal transmissioncable, a monitoring bus, a video storage system and a display screen. The pressure-and-water-resistant camera is arranged at the monitoring position in the shield tunneling machine, the pressure-and-water-resistant camera can be connected with the monitoring bus and the display screen through the video signal transmission cable, and the monitoring bus is further connected with the video storage system. The pressure-and-water-resistant monitoring system in the shield tunneling machine can achieve real-time monitoring and can allow operators on duty to visually understand the internal conditionof the positions required being monitored at any time to discover dangerous cases immediately.

Description

technical field [0001] The invention relates to the technical field of shield tunneling, in particular to a pressure-resistant and waterproof monitoring system inside a shield tunneling machine. Background technique [0002] For the shield machine working deep underground, due to the weight of the soil and the existence of groundwater, certain positions on the machine will inevitably, temporarily or long-term withstand high air pressure, high water pressure, or long-term humidity extremely harsh environment. However, information such as the operation of machinery and equipment in these locations, the wear and tear of components and tools, the position of the liquid level, the state of the soil, and foreign objects in the cabin cannot be directly observed due to limited conditions. For construction technicians, if they can grasp the above information in a timely and accurate manner, it will be of great help to the maintenance of equipment, accident prevention and fault or ri...
