4results about How to "Ensure safe evacuation" patented technology

The application discloses a comprehensive linkage alarm system for fire hazards and structure instability of timber buildings, and relates to the technical field of timber safety monitoring, which comprises the following modules: a multi-dimensional heterogeneous signal acquisition module for collecting data and constructing real-time state monitoring data sets; a structure spectrum benchmark modeling module for constructing a thermal-rigidity attenuation theoretical model; a thermal-frequency correlation analysis module for generating a thermal-frequency deviation degree index; a structure state determination module for identifying timber pyrolysis states and structure instability risks; a cascade response module for executing corresponding fixed-point spraying control, evacuation path planning and alarm output; and a self-adaptive feedback correction module for warehousing data and correcting thermal aging parameters. The application establishes a correlation model of thermal and rigidity by fusing thermal imaging and vibration data, effectively eliminates environmental wind load noise, realizes accurate identification of internal hazards of timber buildings, and improves the accuracy of building monitoring and the efficiency of emergency response.

The utility model discloses a telescopic rod piece and modularization quick assembly apron for shock insulation ditch, set in the top of shock insulation ditch, include: support beam, parallelly arranged two, and both ends are used for hinged connection with the structure connection, support beam is telescopic structure, support rod piece, install on support beam and along the length direction of support beam and set side by side multiple groups, support rod piece with support beam swing joint, make the support rod piece interval can be relatively staggered. The application is through the pin shaft hinged joint node and the flexible apron component cooperation design, ingenious use parallelogram unstable characteristics, through linkage between the rod piece and the rod piece, realize the telescopic between the rod piece, realize the apron in horizontal and vertical two -way self -adaptation displacement, have when the earthquake and not easy to take place the upwarp, threaten personnel safety and the strong carrying capacity, can satisfy the demand of passing through the person, passing the car.

This utility model provides an emergency evacuation door, belonging to the field of emergency door technology. It includes a door frame with a push-pull assembly. The push-pull assembly includes a hinged base panel, a curved track on the side of the hinged base panel, a pulley slidably connected to the inner cavity of the curved track, a hinged sliding panel mounted on the end face of the pulley, an inward-retracting component on the hinged sliding panel, and a locking claw on one side of the hinged sliding panel. A nail-attracting post is provided on the inner side of the hinged base panel. Through the cooperation of the hinged sliding panel and the inward-retracting component, the hinged sliding panel maintains a straight-line movement during displacement, preventing displacement and achieving a balanced expansion of the evacuation passage. The symmetrical area on both sides ensures safer evacuation. Furthermore, the engagement of the inner connecting block and the outer protrusion ensures the hinged sliding panel remains stable on the side, achieving the integrated flipping function of the hinged sliding panel and the hinged base panel.

The utility model discloses a fire-proof and smoke-proof ventilation system for a long-distance underground tunnel, which is characterized in that the internal space of the tunnel is divided into a plurality of adjacent fire-proof subareas, fire-proof walls are arranged among the fire-proof subareas and on the outer side of the fire-proof subarea on the outermost side, and fire-proof doors capable of being opened and closed and fire-proof air ports capable of being opened and closed are arranged on the fire-proof walls. An excess pressure valve is further arranged at the fireproof tuyere and only allows one-way opening, and the allowed airflow flows from the center part of the tunnel to the outer part of the tunnel; an air inlet machine room is connected to the outer portion of the tunnel, a fan is arranged in the air inlet machine room, the output end of the fan is connected with a fireproof air pipe, fresh air outlets are formed in the tail ends of branch pipes, located in all the fireproof subareas, of the fireproof air pipe, and fireproof valves used for controlling on-off are arranged on all the branch pipes of the fireproof air pipe. The scheme has the dual functions of smoke prevention and ventilation, and can meet the requirements of smoke prevention and post-disaster ventilation of small-section and long-distance tunnel engineering at ordinary times.
