Description

Mobile rescue capsule for tunneling of hydropower station TBM tunnel and combining permanent emergency refuge Technical Field The utility model relates to the technical field of hydropower station safety protection equipment, in particular to a movable rescue capsule combining permanent emergency refuge and used for tunneling a tunnel of a TBM (tunnel boring machine) of a hydropower station. Background Along with the rapid development of hydropower industry in China, the construction scale of underground powerhouses of hydropower stations is continuously enlarged, and the TBM (tunnel boring machine) technology is also increasingly applied to the hydropower industry. TBM is a mechanical equipment specially used for tunnel excavation, cuts soil or rock through a rotary cutter disc, conveys the excavated earthwork to the ground through a conveying system, and can select proper types according to different geological conditions to realize efficient and safe tunnel excavation. However, safety protection and emergency rescue face a number of technical challenges in hydropower station TBM tunnel construction and subsequent operation. In the aspect of safety evacuation of the hydropower station underground factory building, the prior art has obvious defects. Hydropower station underground powerhouse cavern groups usually have two safety exits to the outdoor ground, wherein the factory entering traffic hole is used as a main safety exit, and the ventilation hole is used as a standby safety exit. When special accidents such as earthquake and fire disaster are met, once the traffic hole entering the factory is blocked or collapsed, people can only be evacuated from the ventilation hole. At present, nine or ten layers of main and auxiliary workshops are arranged up and down, and only one smoke-proof stairwell and one fire-fighting elevator are provided, and the smoke-proof stairwell and the fire-fighting elevator are combined into a front room. Because ventilation layer and auxiliary factory building bottommost layer difference in height are more than 40 meters, personnel need climb the smoke prevention stairwell that is more than 40 meters high and just can reach the ventilation hole, and this causes very big difficulty to personnel evacuation. More serious, when firing, the fire elevator only serves fire fighters to use, evacuation personnel can reach the ventilation holes through the pre-use room, and the fire fighters and the evacuation personnel are crossed by the line, so that safety risks exist. In the aspect of emergency rescue of TBM tunnel construction, the prior art also has a plurality of problems. The tunnel construction rescue capsule is a safety facility specially designed for tunnel workers and is mainly used for providing a refuge space in the case of sudden accidents. In the prior art, as disclosed in chinese patent CN221879484U, an emergency rescue cabin for a horizontal and inclined integrated TBM construction tunnel is disclosed, which includes a guide rail and a rescue cabin disposed on the guide rail, where the rescue cabin is connected with a traction mechanism, and includes a plurality of unit cabins connected in series to form a sealed cabin body. Although this technology provides basic mobile rescue functions, the following technical drawbacks still exist in practical applications: Firstly, the existing rescue capsule needs to move in real time according to the excavation condition in the TBM tunneling process, but the movement still mainly depends on manual carrying or a simple traction mechanism, so that the labor intensity of workers is greatly increased, the time and the labor are consumed, and the discomfort or the injury of the workers can be caused. Secondly, the emergency life-saving equipment power system under the prior art is fragile, and when an accident occurs, the power is blocked from the outside, and life-support systems such as oxygen supply, temperature regulation and control, air purification, water source guarantee and the like cannot work normally, so that great difficulty is brought to rescue. Thirdly, the existing protective door mostly adopts a simple assembly mode, is fastened on the refuge cave body through bolts, is extremely easy to loosen when dangerous situations occur due to the fact that the weight of the protective door is large, cannot continue to play a protective role, and is pushed outwards when the protective door is commonly used, and if the outer side of the door plate is clamped, the timeliness of rescue can be affected. More importantly, the escape capsule and the permanent emergency refuge facility in the construction period in the prior art are designed separately, and therefore systematic consideration is lacked. After the construction period is finished, the temporary rescue capsule is usually removed, and the permanent emergency refuge facilities need to be rebuilt, so that not only is the resource wasted and the construction cost increased, but
