A fire visual detector and its fire mask

Abstract

The invention provides a fire-fighting visual detector and a fire-fighting mask thereof. The fire-fighting visual detector comprises a camera, a U-shaped framework, and a battery, an imaging lens anda processing plate which are mounted on the U-shaped framework; wherein the U-shaped framework comprises a first mounting support leg, a first mounting support seat, a first supporting part, a middlemounting support seat, a second supporting part, a second mounting support seat and a second mounting support leg which are sequentially connected; the fire-fighting mask comprises the fire-fighting visual detector. The fire-fighting visual detector is simple in structure and detachable, and on the basis that the structure of an existing sealed fire-fighting mask is not changed, the basic functions of rapid escape and rescue in the severe environment are achieved.

Description

technical field [0001] The invention relates to the technical field of infrared detection, in particular to a visual fire detector and a fire mask. Background technique [0002] At the scene of a fire, conditions such as dense smoke, dust, darkness, and mist occur from time to time. During the rescue process, firefighters need to use infrared imaging to capture objects that need rescue. The infrared thermal imager can generate a thermal image on the focal plane of the infrared rays invisible to the human eye, then perform photoelectric conversion, output an electrical signal, and display a visible image that the human eye can see on the visible light display. When used in firefighting, because firefighters often need to wear an isolated full-face fire mask, most of them are currently handheld thermal imaging cameras, with limited hands, and external thermal imaging cameras are vulnerable to harsh environments such as smoke, dust, and water. The other is the helmet-mounted f...

Problems solved by technology

When used in firefighting, because firefighters often need to wear an isolated full-face fire mask, most of them are currently handheld thermal imaging cameras, with limited hands, and external thermal imaging cameras are vulnerable to harsh environments such as smoke, dust, and water. The other is the helmet-mounted fire-fighting thermal imager. Although the hands are freed, it is still placed outside the mask, and the imaging display is exposed outside. The imaging display is prone to fogging and crystallization of water droplets; there are still The disadvantage of the former is that it blocks the line of sight in the case of open vision; moreover, the outside of the mask is not in close contact with the imaging display, and the display screen is blurred by thick smoke and toxic gases; therefore, it cannot be used in these occasions and has disadvantages.

[0003] CN201220193892.8 discloses a helmet-type fire-fighting thermal imager, which includes a shell arranged on one side of the helmet, an infrared optical lens is arranged at the front end of the shell, and an infrared imaging component capable of detecting and forming an image is arranged inside the shell. The front end of the helmet is provided with an imaging device, the housing is connected to the helmet through the first connection structure, the imaging device is connected to the helmet through the second connection structure, and the infrared imaging component is connected to the imaging device; but it is not convenient for the wearer To observe the situation on site, and it is inconvenient to disassemble

[0004] CN201110164374.3 head-mounted internal display fire-fighting night vision dual-purpose thermal imager; The liftable near-eye display in the fire mask is composed of three parts, all of which can be loaded and unloaded; but the structure is complex, and it is not suitable for this application in actual use.
