Description

Fire water drive lighting device convenient to equipment

Technical Field

The invention relates to the field of fire fighting equipment, in particular to a fire fighting water-driven lighting device convenient to assemble.

Background

In the field of fire fighting, fire hydrants, fire-fighting lances and water cannons are the most commonly used fire extinguishing equipment, but in actual fire extinguishing operation and evacuation of personnel, lighting is also important, and due to the power failure and the dense smoke phenomenon accompanying a fire scene, the visual range of firemen or evacuated personnel is greatly influenced. When a fire disaster causes power failure, the existing indoor fire hydrant can only play a role of water supply, so that the sight distance of a fireman is limited in the process of fighting fire.

In the existing patent solutions, for example, CN105854197a relates to an anti-asphyxia hat for fire protection, in which a humidifying breathing device is additionally installed, clean water is filled in the humidifier, the water is sealed in a water box when in standby, when the hat is used, the water can soak a gauze filtering layer of a suction inlet of the hat to filter harmful gas in smoke, an illuminating lamp and a signal transmission device are arranged at the top of the hat, and people escape from a dense smoke area by a more scientific method, but the illuminating lamp is powered by a battery, and the battery is powered by a manual generator. In addition, CN209391135U is a multifunctional safety helmet for fire safety detection in building engineering, and solar panels are adopted for power generation and illumination, but solar panels are heavy in weight, cannot work at high temperature, and are not suitable for firemen.

In addition, taiwan patent certificate I269850 and CN101655230a in the prior art both disclose a fluid-driven lighting device, and the known fluid-driven lighting device utilizes the water flow flowing through the fluid pipeline of the fire-fighting water gun sight to drive the blade of the turbine generator to rotate so as to generate electricity to provide lighting, but the prior fluid-driven lighting device is only suitable for post water-spraying fire fighting lighting outside a fixed site or on a main trunk road of a building, but in actual operation, a fire fighter needs to go deep into a room in the building for searching, so that the relatively heavy water-spraying gun is not convenient to carry with him, the water flow waste is caused after the water-spraying gun is turned off, and at the time, the fire fighter cannot guarantee the cooling and lighting effects when the water valve of the fire-fighting gun is turned off and the fire fighter enters the room for searching, so that the fire fighter falls into a passive state.

In view of this, we propose a fire water driven lighting device that is easy to assemble.
