Embodiment 1

[0019] Embodiment 1 The concrete structure of the present invention:

[0020] like figure 1 , the whole measuring device is welded and placed in the instrument cabin 2 of the buoy body 1, and the inlet and outlet pipes of the seawater are placed in the installation well 3 of the underwater instrument.

[0021] like figure 2 : The water quality parameter measuring instrument placed in the large buoy instrument cabin 2 includes three large containers made of stainless steel, which are respectively a preservation solution container 6 containing a 4M potassium chloride solution, a purified water container 17 and a disinfectant container 16 containing a sodium hypochlorite solution. , a solenoid valve 7 is connected to the lower end of each container, and then connected to the integrated container 10 through the solenoid valve 7 . These three containers should be as large as possible to meet the measurement needs. The present invention adopts a rectangular parallelepiped contain...

Embodiment 2

[0025] Embodiment 2: the use method of the present invention

[0026] In order to prolong the service period of various water quality sensors at sea and reduce the maintenance cost of marine equipment, the invention does not adopt the conventional detection method of placing the sensor directly in the water, but installs the underwater sensor in a suitable position above the waterline. The integrated container 10 is arranged in the buoy body 1 of the large buoy, and the seawater is only contacted when the data is measured. Under the control of the acquisition controller 14, the seawater is pumped into the integrated container 10 equipped with various water quality sensors 9 through the water inlet peristaltic pump 13; the acquisition controller 14 sends a start command to the various water quality sensors 9 to collect various Water quality data; after the collection is completed, the data is stored. When the whole sampling is over, the water outlet peristaltic pump 12 is star...

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...
