Water quality parameter measuring instrument arranged in super buoy and water quality parameter measuring method

Abstract

The invention relates to a water quality parameter measuring instrument arranged in a super buoy and a water quality parameter measuring method. The water quality parameter measuring instrument arranged in the super buoy comprises a buoy body and a water quality parameter measuring instrument, wherein the buoy body comprises an underwater instrument mounting well, and the water quality parameter measuring instrument comprises a water quality sensor and a collection controller which controls an effluent peristaltic pump, an intake peristaltic pump and an electromagnetic valve through cables. The water quality parameter measuring instrument is characterized in that the water quality parameter measuring instrument is mounted in the buoy body and also comprises a disinfectant container, a purified water container and a storage liquid container which are communicated with an integrated container through the electromagnetic valve, and the water quality sensor is arranged in the integrated container. In the invention, the water quality sensor is mounted in the integrated container, the integrated container is arranged in the buoy body of the super buoy, the sensor is soaked in sweater only when water quality data is measured, and the sensor is arranged a cleaning and soaking environment after sampling is finished so as to prolong the life cycle of various underwater sensors in the seawater and decrease the maintenance cost of marine equipment.

Description

technical field [0001] The invention belongs to the field of marine environment detection, and in particular relates to a water quality parameter measuring instrument and a measuring method placed in a large buoy. Background technique [0002] At present, various water quality sensors used on large buoys are placed in the underwater instrument installation wells on the buoy body, and they are completely exposed to the external marine environment no matter in the working process or in dormancy. Very vulnerable to damage, resulting in great economic losses. And because they are placed in the ocean for a long time, various underwater sensors are extremely susceptible to the attachment of marine organisms, thus affecting the measurement accuracy. For example, due to the limitation of probe material and measurement principle, dissolved oxygen and pH sensors under normal conditions generally have a service life of about 1 month, and then the measurement accuracy will be inaccurat...
