Description

Technical Field

[0001] This invention relates to the field of disinfection and sterilization, and more particularly to an ultraviolet disinfection device. Background Technology

[0002] Ultraviolet (UV) lamps are light sources that use ultraviolet radiation to kill microorganisms, bacteria, viruses, or other harmful substances. UV lamps have the ability to sterilize and disinfect, and are relatively simple and environmentally friendly to use.

[0003] Ultraviolet (UV) disinfection is an effective water treatment method used in outdoor drainage ditches, particularly suitable for reducing microbial contamination and pathogens in water. By irradiating water with short-wave UV light, the DNA or RNA of bacteria, viruses, and other microorganisms in the water is destroyed, thus achieving sterilization. For outdoor drainage ditches, UV disinfection can improve water quality and reduce the spread of disease. However, some existing UV light irradiation methods cannot adjust the depth of the UV lamps according to the fluctuating water level caused by weather changes (such as increased or decreased rainfall). In some drainage ditches with insufficient water flow, impurities in the water may deposit near the UV lamps, and insufficient UV penetration can affect sterilization. Furthermore, when not in use, the lamps are exposed, which protects them from damage from accidental impacts. Summary of the Invention
