Automatic tracking and positioning jet flow fire extinguishing system for ship

Abstract

The invention discloses an automatic tracking and positioning jet flow fire extinguishing system for a ship. The automatic tracking and positioning jet flow fire extinguishing system comprises a detector, a central processing unit and an automatic tracking and positioning jet flow fire extinguishing device. The detector is used for collecting and analyzing fire signals in a protection place in real time, whether a fire happens or not is judged, and if the fire happens, a fire alarm signal is sent to the central processing unit. The central processing unit is used for sending a control signal according to the received fire alarm signal to control the automatic tracking and positioning jet flow fire extinguishing device to be started. The automatic tracking and positioning jet flow fire extinguishing device is used for aiming at the fire happening position according to the received control signal to spray water so as to extinguish the fire. The automatic tracking and positioning jet flow fire extinguishing system has the capabilities of initiative fire judging, positioning and starting, the whole process from fire finding, fire confirming, system starting and jet flow fire extinguishing to water jetting stopping after fire extinguishing of the whole system is initiatively completed, the amount of sprayed water is concentrated, the flowing speed is high, the flushing amount is large, water flow can make direct contact with a combustion material to act on the roots of flames, the flames are stripped off from the combustion material so that combustion can be interrupted, and the fire can be effectively extinguished.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a ship automatic tracking and positioning jet fire extinguishing system. Background technique [0002] As the saying goes, water and fire are merciless, and the occurrence of fire has caused great losses to the lives and property of the country and the people. In some unattended large space occasions, once a fire occurs, the losses it causes will be very heavy. Especially in the field of ships, with the continuous development of the world's shipping and naval undertakings, the number and tonnage of ships have increased significantly. At the same time, ship fire accidents and losses are also on the rise year by year. Various types of ship fire and explosion accidents occur frequently, causing a large number of property losses and casualties. The ship is a relatively independent mobile place, and it is very difficult to rely solely on external rescue. Moreover, the interna...

Problems solved by technology

At the same time, ship fire accidents and losses are also on the rise year by year. Various types of ship fire and explosion accidents occur frequently, causing a large number of property losses and casualties

The ship is a relatively independent mobile place, and it is very difficult to rely solely on external rescue. Moreover, the internal space of the ship is small, the equipment is concentrated in a complex environment, and the number of fire sources increases. increase, it is more difficult to implement escape and fire rescue

Especially for some ships carrying inflammable and explosive materials, cars and passengers, not only a large number of personnel and equipment are concentrated in a limited space, but also a large number of inflammable and explosive materials are concentrated in the cabin, which makes the danger of fire The loss and damage caused by fire accidents will be more serious

The traditional automatic sprinkler system is limited by the temperature of the temperature sensing element of the sprinkler head. Since the temperature of the smoke plume in the early fire is usually difficult to reach the starting temperature of the automatic sprinkler system, the sprinkler head that is activated by temperature changes cannot Effectively play the role of early fire response and fire extinguishing, making it lag in detecting fire source and extinguishing fire, making it difficult to suppress and extinguish the fire source in the early stage of fire

Although the open deluge system activated by smoke and temperature detectors can be used in places with dense population or fast fire spread, which can solve the above problems and improve the fire extinguishing efficiency, but the system consumes too much water and is not suitable for non-fire Area prone to greater secondary water damage
