Underwater ultraviolet sterilizer

Abstract

The invention discloses an underwater ultraviolet sterilizer. The underwater ultraviolet sterilizer can be used in fresh water and sea water, and can perform underwater sterilization and biological growth inhibition by adopting ultraviolet radiation of which the wavelength range is 260-280 nm. The underwater ultraviolet sterilizer can be mounted near different types of field measurement sensors, and can effectively solve the problem that the biological growth in water is over exuberant, so that the measurement sensors drift, and sensitive elements are damaged. The underwater ultraviolet sterilizer consists of a transparent watertight protective cover, a luminous baseplate, an ultraviolet light emitting diode, a switch time schedule controller, a pressure-resistant watertight casing, a signal cable and the like, can realize instant starting, continuous light emitting and timed light emitting, is good in sterilization effect, is free of movable mechanical part and chemical substance precipitation, high in reliability and free of pollution on environment, and plays an obvious application effect on protection of marine measurement sensors, which are placed underwater in long term and are high in environment protection requirements and complex in geometric shape, from biological growth and adhesion.

Description

technical field [0001] The invention relates to an underwater anti-biological adhesion protection device, in particular to an anti-biological adhesion protection device for on-site measurement sensors in the ocean. Background technique [0002] In the field of marine research, the seawater environment is a special and extremely complex corrosion environment. There are various organisms growing in the seawater. The growth and attachment of marine organisms are gradually realized according to the following process: the bacterial biofilm in the seawater will adhere to the surface of the instrument. The larvae of plankton provide a foothold, and plankton can serve as bait for barnacles and mussel adults, promoting the attachment of sedentary marine organisms and producing calcareous deposits, providing a suitable environment for the growth of algae plants, and the growth of algae plants Reproduction further provides a food source for resident organisms, and this cycle allows mar...

AI Technical Summary

Problems solved by technology

[0005] There are many defects in the above-mentioned devices and methods for preventing biological growth and sterilization underwater. The limitations of the mechanical devices include poor reliability of the actuators for underwater activities, high power consumption and difficulty in effectively protecting marine sensors with complex geometric shapes such as spherical and tubular shapes. Irregular shape; the chemical dosing method has a short sterilization period and requires continuous dosing, and it is easy to cause a series of environmental pollution problems
