LONG-TERM SEAFLOOR HEAT FLOW MONITORING PROBE BASED ON UNDERWATER ROBOT PLATFORM

摘要

The present invention discloses a long-term seafloor heat flow monitoringprobe based on anunderwater robot platform, comprising a support probe lance and a plurality ofself-containedtemperature measurement units. The plurality of self-contained temperaturemeasurement units arefixed on the support probe lance at equal intervals in spiral distribution toform a distributed multi-pointtemperature measurement structure for long-term monitoring of temperaturefluctuations of seafloorsediments at different depths; and each self-contained temperature measurementunit comprises acasing, a battery, a temperature measurement circuit board, a sensor packagingprobe head and atemperature sensor, wherein both the battery and the temperature measurementcircuit board areinstalled in the casing, the sensor packaging probe head is fixed at one endof the casing, and thetemperature sensor is installed in the sensor packaging probe head andelectrically connected with thetemperature measurement circuit board. According to the present invention, thetemperature sensorsare in close contact with the seafloor sediments, and meanwhile, the self-contained temperaturemeasurement units are installed in a spiral manner, thereby guaranteeing thateach temperature sensorcan come into contact with the sediments undisturbed, and maximallyguaranteeing the rapidness andaccuracy in the temperature measurement of the sediments.
