Description

Technical Field

[0001] This invention relates to the application of lasers in the field of fire safety. Technical Background

[0002] Fire hoses are essential equipment widely used in fire rescue. When placed on the ground at night, they are often run over by vehicles and can also cause pedestrians to trip and get injured. Current technologies use long-afterglow luminous markers or reflective thread wrapping for marking. These technologies require external auxiliary light sources to produce a short-term effect. In daily use, fire hoses are connected in multiple sections and cross various complex environments such as streets, roads, grasslands, and forests, requiring active luminous markings for warning.

[0003] This invention discloses a fire hose luminescent connector that utilizes the principle of medium optical transmission to emit light by irradiating a water column with laser light. The confined transmission of light causes the fire hose to emit light actively. The invention includes: a connector cavity, a light source, a light source controller, a beam refractor, an outlet connector, and an inlet connector. Its key features are: the light source is a visible blue-green laser coupled with a quartz optical fiber; the light source controller includes a power supply, a water flow sensor, a light source switch, and a beam adjuster; the outlet and inlet connectors are equipped with bayonets, allowing them to be connected to the middle of two sections of fire hose. When flowing water is injected into the fire hose, turning on the laser light source switch causes the laser to emit light through confined diffusion in the water flow, resulting in the fire hose emitting light as a whole.

[0004] This invention can be widely used for marking fire hoses, providing nighttime luminous warnings for temporary water pipes, and facilitating nighttime firefighting operations at heights. It clearly marks the location of fire hoses, which is beneficial to the safety of personnel and vehicles. Summary of the Invention

[0005] A fire hose luminescent connector includes: a connector cavity, a light source, a light source controller, a beam refractor, an outlet connector, and an inlet connector; characterized in that: the light source is a visible blue-green laser coupled with a quartz optical fiber; the light source controller is equipped with a power supply, a water flow sensor, a light source switch, and a beam adjuster; the outlet connector and the inlet connector are equipped with bayonets, which can be connected to the middle of two sections of fire hose respectively. When flowing water is injected into the fire hose, the laser light source switch is turned on, and the laser emits light through confined diffusion in the water flow, causing the entire appearance of the fire hose to emit light.

[0006] The blue-green laser source in this invention has a power of 0.1-10 watts. Blue-green light travels farther in water, while red light travels shorter distances. Unidirectional laser illumination is achieved by coupling an optical fiber, which is fixed within the connector cavity. The fiber utilizes the dynamic refraction of the water flow to diffuse and confine the laser beam within the water.

[0007] The light source controller in this invention is located on the surface of the connector cavity. The light source controller is equipped with a rechargeable lithium battery power supply, a water flow sensor, a laser light source switch, and a beam intensity adjuster. When the water flow sensor cannot detect water flow, the laser light source switch automatically turns off, and the laser stops irradiating, ensuring safety.

[0008] The connector cavity of this invention is provided with a beam refractor at the bottom. The beam refractor is a glass-coated or metal-coated reflector, which can cause the scattered laser to be refracted into the water a second time, thereby reducing laser loss.

[0009] The outlet connector and inlet connector of this invention have standard spiral bayonet, which can be connected to fire hoses, fire hydrants and fire guns, and the light emission direction can be adjusted according to different occasions.

[0010] The fire hose in this invention is a white woven hose. At night, the white woven hose can clearly transmit laser beams reflected by the water, and the hose exhibits a blue-green dynamic fluorescence at night.

[0011] The connector cavity in this invention is formed by metal casting, and the copper material has good processing and heat dissipation characteristics. It contains an optical fiber and a beam refractor, and has an outlet connector and an inlet connector at each end.

[0012] The coupled silica fiber in this invention can refract blue-green laser light, the fiber length is smaller than the connector cavity size, and the silica fiber has bending flexibility. Attached Figure Description

When the fire hose is filled with flowing water, the laser light source switch is turned on, and the laser emits light by generating a confined diffusion propagation in the water flow, and the entire appearance of the fire hose emits light.

[0015] The blue-green laser light source in this invention has a power of 0.1-10 watts. Blue-green light travels farther in water, while red light travels shorter. Since fire hoses are typically 25 meters long, this invention designs the laser to be focused at 15 meters. Unidirectional laser illumination is achieved through a coupled optical fiber, which is fixed within the connector cavity. The fiber utilizes the dynamic refraction of the water flow to diffuse and confine the laser beam within the water.

Its metal material has good heat dissipation. It is also equipped with a rechargeable lithium battery power supply, a water flow sensor, a laser light source switch, and a beam intensity adjuster. When the water flow sensor cannot detect water flow, the laser light source switch automatically turns off, and the laser stops irradiating, ensuring safety.

[0017] The connector cavity of this invention is equipped with a beam refractor at its bottom. The beam refractor is made of glass or metal coating for reflection, which allows the scattered laser to be refracted a second time into the water, reducing laser loss. The outlet and inlet connectors of this invention have standard spiral bayonets, which can be attached and detached from fire hoses, fire hydrants, and fire nozzles, and the light emission direction can be adjusted according to different occasions.

[0018] The fire hose in this invention is a white woven hose. At night, the white woven hose can clearly transmit laser beams reflected by the water, and the hose exhibits a blue-green dynamic fluorescence at night.

The coupling silica optical fiber in this invention can refract blue-green laser light; the fiber diameter is 0.1-0.5 mm, and the fiber length is smaller than the connector cavity size. The silica optical fiber exhibits flexibility in flowing water.

[0020] The advantages of this invention are:

[0021] The advantages of this invention are safe active laser light transmission, convenient mobile use, and wide applicability at night for marking fire hoses, providing nighttime illumination warnings for temporary water pipes, and facilitating nighttime firefighting operations at heights. It clearly marks the location of fire hoses, which is beneficial to the safety of personnel and vehicles. The normal use of fire hoses is not affected, and stepping on, bending, or running over them will not affect the light emission.
