Abstract

The utility model provides a fire-fighting automatic polling fire-extinguishing control cabinet. The fire-fighting automatic polling fire-extinguishing control cabinet is composed of a local area network control center, a control cabinet and a fire-fighting pipeline. When a smoke open fire sensor detects a fire, the smoke open fire sensor transmits a signal to the local area network control center, the local area network control center reports the information to the 119 control center, a fire-fighting water pump control cabinet starts a No.1 fire-fighting water pump to supply water for a looped network fire-fighting pipe, an electromagnetic switch corresponding to the smoke open fire sensor is switched on, and a spray nozzle sprays water to extinguish fire; when a plurality of spray nozzles spray water to cause the pressure of the looped network fire-fighting pipe to be insufficient, a pressure sensor transmits a signal to the fire-fighting water pump control cabinet, and a NO.2 fire-fighting water pump is automatically opened to increase pressure. A water return pipe and an overflow valve are installed at two sides of each fire-fighting water pump, and when the pressure in the looped network fire-fighting pipe exceeds the standard, water is injected to a municipal water supply pipe.

Description

Fire-fighting automatic detecting fire extinguishing switch board

Technical field

This novel fire-fighting equipment that belongs to relates in particular to a kind of novel fire-fighting automatic detecting fire extinguishing switch board.

Background technology

China is in the high-speed developing period, and large-scale urban construction has expedited the emergence of the crowded places such as a plurality of Tall Office Buildings, office space, guild hall place, commercial building, supermarket, and these crowded places all are provided with fire fighting device.In the fire cases that China has occured, it is very general that fire fighting device does not have corresponding problems in role a crucial moment.See in working in addition that all there is the problem of establishing light management of rebuilding in many fire fighting devices, many fire fighting devices just check and accept at fire department that running status was good at that time, after obtaining the fire-fighting quality certification, generally think little of the maintenance and management of fire fighting device, in case cause breaking out of fire, fire pump or because various reasons such as rust is dead, booster, burn-down of electric motor, shaft coupling fractures, cause fire pump can not bring into play at crucial moment due effect, cause putting out a fire ineffective, loss is enlarged, even cause casualties.For guaranteeing national wealth and the people's life security, be sought after a kind of can automatically going the rounds on the market and detect the fire-fighting equipment situation, assurance equipment normally moves, and the system and device that can in time put out a fire when fire occurs and process.

Summary of the invention

This novel purpose is: provide a kind of fire-fighting automatically to control and patrol and examine and extinguishing device, smog or hot gas when fire occurs in the automatic capturing detection zone, start thereby send sound and light alarm and control automatic fire extinguishing system, the output of other function devices links, control emergency lighting, evacuation mark, accident broadcasting, communication, fire water-supply and anti-smoke removal facility are realized the automation of monitoring, warning and fire extinguishing.

This novel technical scheme is in order to achieve the above object: a kind of fire-fighting automatic detecting fire extinguishing switch board; Formed by local area network control center, switch board and fire main, it is characterized in that: when smog naked light sensor has detected the fire generation, signal is passed to local area network control center, and report to 119 control centres by local area network control center, starting No. 1 fire pump by the Firefighting Pump Control cabinet simultaneously supplies water to the looped network extinguishing pipe, the electromagnetic switch valve corresponding with smog naked light sensor opened the fountain head sprinkling fire; When a plurality of shower nozzle water sprays, when causing the interior pressure of looped network extinguishing pipe inadequate, pressure sensor is transmitted to the Firefighting Pump Control cabinet with signal, starts No. 2 fire pumps and automatically opens supercharging.

In order to guarantee the safety of fire main and fire pump, return pipe and overflow valve are equipped with in the pump both sides, when looped network extinguishing pipe internal pressure superpressure, the water notes are got back in the municipal water supply pipe.

Needs in order to guarantee to put out a fire are equipped with fire cistern in the pipeline.

The beneficial effect that this is novel

This novel control appliance adopts intelligent control equipment, utilize Programmable Logic Controller that whole system is carried out automation control, realize manually, automatic equal controllable mode, can be directly and fire protection control center and far-end fire-fighting signaling interface, be convenient to centralized control and management.
