Embodiment approach 1

[0025] 1. Measuring device for crack width in polar sea ice

[0026] The polar sea ice ice crack width measuring device of the present invention consists of a capacitive ice crack detection sensor 1, a fixed spring support 2, and a measuring instrument 3 (see attached figure 2 ), fasteners 4, batteries 5, antennas 6, power wires 7 and other parts (see attached figure 1). The capacitive ice crack detection sensor 1 is a triangular pyramid sensor composed of three capacitive ice thickness measuring sensors at a certain angle. The fixed spring support 2 is composed of three hard steel springs with a diameter of 5 cm welded end to end to form an equilateral triangle plane support. One end of each capacitive ice thickness measurement sensor is respectively fixed on the three corners of the triangular support. Its function is to play a fixing role to each capacitive ice thickness measuring sensor on the one hand, and on the other hand, when the triangular pyramid type capaci...

Embodiment approach 2

[0038] Capacitive ice crack detection sensor 1 and its structure (see attached image 3 ) consists of three capacitive ice thickness measuring sensors at a certain angle to form a triangular pyramid sensor. In addition to being uniformly provided with capacitor plates 15 inside each capacitive ice thickness measuring sensor, there is also a connecting wire 16 for connecting three sensors, and a non-metallic glass rod is also arranged inside each sensor for reinforcing the sensor. Said material is then sealed in a rod with insulating epoxy material 17 . Others are the same as Embodiment 1.

Embodiment approach 3

[0040] Another effect of the fastener 4 is that it weighs 6 kilograms, and the effect of its gravity can make the detection sensor of the whole set of triangular pyramid type keep vertically upright with the ice surface, and the others are the same as in Embodiment 1.

Abstract

An automatic measuring device and method for measuring the crack width of polar sea ice, the purpose of which is to provide a real-time automatic measuring method for the crack width of polar sea ice, so as to solve the problem of loss of life and property caused by sea ice cracks during sea ice transportation during polar expedition activities. The device includes a capacitive ice crack detection sensor, a fixed spring support, a measuring instrument, a fastener, an antenna and the like. The invention uses a capacitive ice crack detection sensor to measure the height of the capacitive ice thickness sensor submerged by seawater between ice cracks to calculate the width of the ice crack, and uses Iridium satellite communication to realize wireless transmission of data, realizing remote wireless monitoring of the width of ice cracks in polar sea ice The automatic measurement method overcomes the large error and non-real-time problems in the existing sea ice crack measurement technology, thereby disclosing an automatic dynamic sea ice crack width measurement device and measurement method mainly used in the field of polar investigation.

Description

technical field [0001] The invention discloses an automatic measuring device and a measuring method for the crack width of polar sea ice, which belong to the technical field of automatic detection and measurement, and are mainly applied in the field of automatic monitoring of polar sea ice. Background technique [0002] Polar sea ice cracks are cracks in sea ice due to the ebb and flow of seawater tides and the thermal effect inside sea ice during the growth and change of sea ice. Its width generally increases over time. In the north and south poles, the wind and snow are relatively strong, and ice cracks are often covered by thick snow, which makes it difficult to find ice cracks and judge their width through satellite photos and visual observations. In the expeditions to the polar regions conducted by countries all over the world, it is necessary to use snowmobiles to transport materials on sea ice, and ice cracks are the greatest danger to transport vehicles and drivers ...
