Anti-marine organism-adhesion marine conductivity-temperature-depth measuring instrument

Abstract

The invention discloses an anti-marine organism-adhesion marine conductivity-temperature-depth measuring instrument. The anti-marine organism-adhesion marine conductivity-temperature-depth measuring instrument includes a main body for the measuring instrument, wherein a conductivity sensor, a temperature sensor and a pressure sensor are arranged on the main body for the measuring instrument; and ultraviolet ray light emitting diodes for irradiating the conductivity sensor, the temperature sensor and the pressure sensor are also arranged on the main body for the measuring instrument. The invention relates to a marine novel instrument which can utilize ultraviolet radiation to eliminate and restrain the situation that the performance of the conductivity-temperature-depth measuring sensor is invalid and the monitoring data is not reliable because of organism adhesion. The instrument has the ability to work in place continuously over a long period of time, and the maximum overpressure resistant depth is 1500m. The instrument utilizes the integrated design; the plurality of ultraviolet ray light emitting diodes are integrated in the instrument and are used for performing regular radiation for each measurement unit respectively. The anti-marine organism-adhesion marine conductivity-temperature-depth measuring instrument has great significance for acquiring marine monitoring data with high accuracy and high reliability and improving the stability of the marine measurement sensors.

Description

Technical field [0001] The invention relates to a temperature and salt depth measuring instrument, in particular to a marine temperature and salt depth measuring instrument with the function of preventing the adhesion of marine organisms. Background technique [0002] Marine organisms are mainly formed by accumulation of marine microorganisms, plants, algae or animals, and they are most serious from the surface of the sea to 500 meters underwater. Because these organisms are adsorbed on the surface of ocean observation platforms or instruments for a long time, they will have a great impact on the performance and measurement accuracy of the system itself. Physical ocean observation instruments that are subject to long-term biological attachment, such as seawater temperature sensors, pressure sensors, conductivity sensors, etc., whose observation results are usually blocked or obstructed due to biological attachment of the measuring unit or sensing element, which affects the stabil...

Problems solved by technology

The chemical reagent method mainly uses an antimicrobial agent (tributyltin), but due to its toxicity, it will affect other surrounding marine organisms and the environment, and most countries have banned its use.

The mechanical cleaning method uses a device similar to a car wiper to perform regular reciprocating mechanical cleaning on the measurement unit or the observation window. However, due to the long-term use of the cleaning wiper, there will be problems such as deformation, and this device needs to drive the motor to continue to rotate under high pressure underwater. It needs to consume a lot of power to work, and it is not suitable for ocean observation equipment with clear power consumption restrictions.

Up to now, there are no effective technical means to eliminate marine biofouling to alleviate the impact of underwater observation systems from biofouling
