Accurate-spraying superfine dry powder extinguishing equipment for intelligent pipe rack

Abstract

The invention relates to accurate-spraying superfine dry powder extinguishing equipment for an intelligent pipe rack. The accurate-spraying superfine dry powder extinguishing equipment includes a regulating mechanism, a mounting plate, a shell body and two guide mechanisms, the guide mechanisms include rotating mechanisms, guide plates and boosting mechanisms, and the rotating mechanisms include side plates, first motors, first driving shafts, sliding blocks and support rods; and the boosting mechanisms include driving assemblies, driving plates, two telescopic assemblies and a plurality of boosting assemblies, and the boosting assemblies include spray nozzles, air pipes, air cylinders, first pistons and clamping assemblies. According to the accurate-spraying superfine dry powder extinguishing equipment for the intelligent pipe rack, the rotating mechanisms can drive the guide plates to rotate to enable superfine dry powder to be sprayed out along channels formed by two guide plates, thereby reducing the influence of dry powder due to the wind force during fire disasters, not only that, high speed air is sprayed from the boosting mechanisms to accelerate the superfine dry powder, thereby further reducing the influence of the superfine dry powder due to the fire-heating air pressure, the accurate spraying of fire extinguishing equipment can be ensured, and a flame extinguishingability of equipment is enhanced.

Description

technical field [0001] The invention relates to the field of smart pipe gallery equipment, in particular to an ultra-fine dry powder fire extinguishing device for a smart pipe gallery with precise spraying. Background technique [0002] Smart pipe gallery, that is, the comprehensive monitoring system of urban underground pipe network, including asset equipment monitoring system (power cable monitoring system, communication optical cable monitoring system, water supply pipeline monitoring system, thermal pipeline monitoring system, natural gas pipeline monitoring system), environmental monitoring system, pipe Corridor monitoring system, electronic inspection management system, electronic inspection management system, fire protection system, etc., whose monitoring scope comprehensively covers the safety of pipeline operation in the underground pipe gallery and the status of the pipe gallery space and auxiliary facilities, etc., and is the "lifeline" of the city The reliable op...

Problems solved by technology

[0003] In order to protect the personal safety of the internal facilities and staff of the pipe gallery, fire-fighting devices are usually installed everywhere in the pipe gallery. Among all kinds of fire-fighting devices, the ultra-fine dry powder automatic fire extinguishing device can instantly start fire extinguishing in case of fire or fire signal, It embodies the advanced concept of rapid response, early suppression, and high-efficiency fire extinguishing, and is widely used in the fire protection system of pipe gallery with small amount of fire extinguishing agent, simple system and low cost. In the process of using ultra-fine dry powder fire extinguishing device, the main Relying on the distribution of dry powder in the air, the protection of the pipe gallery facilities below is realized. However, the dry powder particles are small and light in weight, so that after the dry powder is sprayed, it often encounters the "fire wind pressure" generated by the intense fire inside the pipe gallery, resulting Fine dry powder is blown or swept away, reducing fire suppression effectiveness
