Description

Technical Field

[0001] This utility model relates to the field of helicopter fire alarm function testing technology, specifically a multifunctional and portable fire alarm function testing instrument. Background Technology

[0002] In order to monitor whether the important internal component compartments of the helicopter are overheating and catching fire during use, fire detection sensors are placed in important component compartments such as the engine compartment and APU compartment. The fire detection sensors detect the UVC band radiation value to determine whether a fire has occurred. These fire detection sensors in important component compartments also need to be tested regularly to prevent the fire detection sensors from malfunctioning.

[0003] Currently, mercury lamps are commonly used to detect fire alarm sensors. However, mercury lamps must be connected to AC power, which is inconvenient for testing in the field. Furthermore, the UVC radiation produced by mercury lamps is relatively weak, resulting in a slow response from the fire alarm sensors and making it difficult to accurately measure their reaction time. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a multifunctional and convenient fire alarm function test instrument to address the above-mentioned shortcomings.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: A multifunctional portable fire alarm function tester includes a housing, a night-use module, a day-use module, and a battery. The night-use module, day-use module, and battery are respectively disposed inside the housing. Both the night-use module and day-use module are electrically connected to the battery and are connected in parallel. The night-use module is used to simulate a fire signal using a xenon lamp, while the day-use module is used to simulate a fire signal and create a small-scale sterile environment using an LED UVC lamp panel. The upper surface of the housing also has a module selection switch and a voltage and current monitoring module. The module selection switch is used to select whether the night-use module or the day-use module is connected in series with the voltage and current monitoring module. The voltage and current monitoring module includes a voltage and current detection module and a display. The voltage and current detection module is used to detect the current and voltage of the selected night-use module or day-use module circuit, and the display is used to display the current and voltage detected by the voltage and current detection module.

[0006] Furthermore, the night-use module includes a xenon lamp, a current regulator, and a high-voltage transformer. The xenon lamp is located on the front side of the housing, and the high-voltage transformer and the current regulator are located on the inner side of the housing. The high-voltage transformer, the current regulator, and the xenon lamp are connected in series. The high-voltage transformer stably outputs the working voltage of the xenon lamp, and the current regulator is used to output the working current of the xenon lamp. A cooling fan is connected in parallel to the circuit of the night-use module.

[0007] Furthermore, a filter glass is provided on the front side of the xenon lamp. The wavelength range of the light from the xenon lamp after being filtered by the filter glass is 200-1000nm, with a peak wavelength of 608nm. The ultraviolet waves in the 200-260nm band are used to simulate fire signals.

[0008] Furthermore, the daily-use module includes an LED UVC lamp board and a transformer module. The LED UVC lamp board and the transformer module are connected in series. The LED UVC lamp board is used to simulate fire signals and create a small-scale sterile environment outdoors. The transformer module is used to output the working voltage of the LED UVC lamp board. A heat dissipation module is connected in parallel on the circuit of the daily-use module.

[0009] Furthermore, the light wavelength range of the LED UVC lamp panel is 200-400nm, with a peak value of 231nm.

[0010] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: This invention uses battery power, eliminating the limitation that traditional mercury lamp detection requires AC power, making it convenient to detect helicopter fire alarm sensors in complex environments such as the field.

[0011] After being filtered by the filter glass, the ultraviolet light in the 200-260nm band of the xenon lamp can effectively simulate fire signals. Compared with the weaker UVC band radiation produced by the mercury lamp, it enables the fire alarm detection sensor to react more quickly and facilitates accurate detection of its reaction time. At the same time, the ultraviolet light in the UVA and UVB bands can be used for curing polymer adhesives, and the visible light band is used for lighting, making it versatile in function.

[0012] The LED UVC light panel has a wavelength range of 200-400nm and a peak wavelength of 231nm. It can effectively simulate fire signals at night and create a small-scale sterile environment outdoors, meeting the detection needs of different scenarios.

[0013] The night-use module and the day-use module are connected in parallel and electrically connected to the battery, allowing them to work independently without interfering with each other. A cooling fan is connected in parallel to the night-use module circuit to ensure heat dissipation during xenon lamp operation, improving equipment stability and lifespan. The module is selected by rotating the module switch, and the display shows the current and voltage of the selected module circuit, facilitating operation and monitoring.
