Embodiment Construction
[0028] The structure, operation process, testing process and implementation examples of the present invention will be further described below in conjunction with the accompanying drawings.
[0029] figure 1 It is a schematic diagram of the external structure and assembly method of the present invention. The cylindrical heat-insulating shell 4 is a hollow thin-walled structure with an open top and a 1.5 cm deep thread is processed on the top for connection and fixation with the tapered top 2. The cylindrical heat-insulating shell 1 and the tapered top 2 The gaps are sealed by a waterproof rubber gasket 9, and the side of the cylindrical heat-insulating shell 1 has a vertical groove that is perpendicular to the cross-section of the cylinder, and a number of round holes are distributed in the groove for fixing the platinum resistance temperature sensor 3 and after the sensor is fixed All are sealed. The platinum resistance sensor 3 is in direct contact with the external sea ice ...

Abstract
The invention belongs to the technical field of sea ice testing, and provides a device for testing a heat flux coefficient between sea ice and seawater. A plurality of platinum resistance temperaturesensors, a waterproof sealing low-temperature-resistant signal emitter, a waterproof sealing low-temperature-resistant data collector, a balancing weight and the like are installed in a cylindrical heat insulation shell with a conical top part, an umbrella-shaped anti-extrusion support is arranged to improve the structural strength, and data can be transmitted to a land end through a top end wireless transmission antenna. The device can float in seawater to test the vertical temperature gradient of primary ice and thin ice which are small in thickness, the structural design can resist the influence of severe environmental conditions such as snowfall, low temperature and seawater splashing on the device, and extrusion damage to the device in the sea ice drifting process can be resisted.
Description
technical field [0001] The invention belongs to the technical field of sea ice testing, and relates to a testing device for thermodynamic parameters of sea ice, in particular to a heat flux coefficient measuring device between sea ice and seawater. Background technique [0002] my country's Bohai Sea is affected by sea ice to varying degrees every winter. The existence of sea ice has seriously affected production and living activities such as marine transportation, aquaculture, and oil and gas exploitation in the Bohai Sea. Forecast accuracy and reliability of ice and ice conditions. In the study of sea ice growth process, the heat flux coefficient between ice and water is an important parameter to predict the growth rate of sea ice, and the heat flux coefficient is mainly calculated by the shape of the temperature profile of the ice-water interface. However, the sensors and other test devices used in the current sea ice temperature test technology have not been developed fo...
