Abstract

The invention discloses a damp-proof system of a data acquisition box, and particularly relates to a damp-proof system of a data acquisition box of an HDPE floating net cage. The damp-proof system comprises a floating buoy and a first drying device, wherein the floating buoy can make repeated up-and-down floating along with a sea wave when a sea surface is in a continuous up-and-down fluctuation state; that is to say, a gas pressure value in a high-pressure gas storage tank of the floating buoy is continuously increased; whenever the gas pressure value in the high-pressure gas storage tank reaches set P1, partial high-pressure gas in the high-pressure gas storage tank is dried by the first drying device and then enters the data acquisition box until a gas pressure value in the data acquisition box reaches the set P1; partial air in the data acquisition box is discharged from a second air discharge hole; and the dryness of the air in the data acquisition box is gradually improved by allowing dry air to enter and discharging mixed air with certain humidity. The damp-proof system solves the technical problem of damp-proofing of the data acquisition box of the HDPE floating net cage, and has the advantages of simple structure, easy mounting, good use stability and the like.

Description

technical field [0001] The invention relates to a moisture-proof system for a data collection box, in particular to a moisture-proof system for a data collection box of an HDPE floating net cage. Background technique [0002] Modern marine fish farming is gradually developing towards the model of open sea and green cage culture, and a large number of HDPE floating cages are used for seafood culture. [0003] In addition, modern deep-water cage culture is inseparable from the automatic detection of breeding environment parameters. Aquaculture environment parameters include hydrological environment parameters (for example, water flow velocity, wind speed), water quality parameters (for example, dissolved oxygen, temperature, redox, nitrite, ammonia nitrogen, pH value and other six factors of aquaculture water quality), among which water quality parameters are more Important, its data collection is the basis of the automated breeding process. [0004] The existing data acquis...
