Large-flow adjustable firefighting water-sprinkling sprayer

Abstract

The invention discloses a large-flow adjustable firefighting water-sprinkling sprayer. During practical use, the large-flow adjustable firefighting water-sprinkling sprayer is mainly used for large-flow firefighting conditions during big fire; when fire breaks out, after a glass ball is broken due to heating, temperature sensors on a bearing plate perform temperature induction on a fire source direction and transmit signals to a controller; after the controller receives the signals of the temperature sensors, the controller controls a motor of a telescopic driving device which is opposite to afire source in direction to be started; and the motor drives a corresponding gear to rotate, and further a corresponding connection chain is pulled upwards. Besides, when the fire source is located between a left side and a right side, telescopic driving devices close to two sides of the fire source can perform contraction control on corresponding connection chains synchronously, so that targetedfire extinguishing can be performed in the direction; besides, elastic supporting sleeves which sleeve the connection chains exert an elastic supporting effect on the connection chains, so that supporting strength of the connection chains to a water spilling disc can be enhanced; and a large-flow water flow can be stably baffled and guided by the water spilling disc, so that precise spraying fireextinguishing is realized.

Description

technical field [0001] The invention relates to the field of fire-fighting equipment, in particular to a large-flow adjustable fire-fighting sprinkler head. Background technique [0002] The automatic sprinkler system of the fire sprinkler is to automatically spray water to extinguish the fire when a fire occurs. It has the fire prevention effect of blocking flame penetration, heat absorption and smoke isolation, and can carry out early fire extinguishing for high-risk fires. Therefore, many Large factories, workshops, halls, theaters and other buildings are equipped with fire sprinklers. But the fire sprinkler head in the prior art, or because have adopted impact type water spray, or because its rotational speed is higher, cause the water atomization phenomenon that sprinkler head ejects to be very serious, spray water particle is little, and jet flow rate is less, The smaller the water particles, the smaller the ability to penetrate the hot air flow of the fire and reach ...

But the fire sprinkler head in the prior art, or because have adopted impact type water spray, or because its rotation speed is higher, cause the water atomization phenomenon that sprinkler head ejects is very serious, and spray water particle is little, and jet flow rate is less, The smaller the water particles, the smaller the ability to penetrate the fire hot air flow and reach the surface of the burning object, and the lower the fire extinguishing ability. Water fire extinguishing has certain limitations in its use
