Embodiment Construction

[0027] The technical solution of the present invention will be further described in conjunction with the accompanying drawings. Such as figure 1 Shown is the principle diagram of the underwater ultraviolet sterilizer involved in the patent of the present invention. figure 2 A schematic diagram showing the structure of the underwater ultraviolet sterilizer involved in the patent of the present invention.

[0028] Such as figure 1 As shown, the underwater ultraviolet sterilizer 1 is fixed on the protected sensor 2 through a special fixture 4, and the 260-280nm ultraviolet beam 3 emitted by the underwater ultraviolet sterilizer 1 is irradiated on the surface of the protected sensor 2, and the ultraviolet beam 3 The irradiated area is an effective sterilization protection area. The higher the output power of the underwater ultraviolet sterilizer 1, the longer the irradiation time, and the closer the distance to the protected sensor 2, the better the sterilization effect. The ...

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...
