Embodiment Construction

[0050] The following examples can make those skilled in the technical field understand the present invention more comprehensively, but do not limit the present invention in any way.

[0051] figure 1 and 2 As shown, the present invention provides a kind of mechanical rotary polar subglacial mobile ice core sampler, the polar subglacial mobile ice core sampler is mainly composed of a sampling part, a power part, an auxiliary part part, a cabin body (a lithium battery is contained in the cabin body) , electric control cabin, solenoid valve box, cold and heat source), etc. There are 4 mechanical arms 3 in total, which are evenly distributed around the sampler. The mechanical arms 3 are connected to the base 2 through the bearing seat 20, and the base 2 can rotate freely. In addition, no matter whether it is the rotary motor 9 or the linear motor 10, it needs to be sealed, which is realized by means of oil seal, and the power transmission and control are realized by watertight c...

Abstract

The invention discloses a mechanical rotary type mobile ice core sampler in the sub-ice layer of the polar region, which comprises a cabin body with a sealed hollow structure and a cold and heat source in the hollow structure, and a horizontal propulsion device installed on the lower surface of the cabin body The upper surface of the cabin is provided with a base, the base is concentrically arranged with the vertical propeller and one end of the base is fixedly connected with the power output end of the vertical propeller, and the other end of the base rotates It is connected with a mechanical arm that can rotate around its own joints. The free end of the mechanical arm is threaded to connect the hot and cold heads. The hot and cold heads are connected to the cold and heat source, and the cold and heat source cools or heats it; the upper and lower surfaces of the cabin are also sealed and installed separately. The rotary motor and the linear motor are connected with each other, and the output end of the rotary motor is threadedly connected with the sampling drill bit. The invention reduces the size of equipment and lowers the cost of coring.

Description

technical field [0001] The invention relates to the field of polar ice core sampling, in particular to a mechanical rotary polar subglacial mobile ice core sampler. Background technique [0002] Polar research can understand the mechanism of climate change. Through the sampling and analysis of polar ice cores, ancient climate changes can be reversed, and the relationship between human activities and climate change can be understood through ice core encased gas dating. Through polar ice core sampling analysis, deepening climate change research and reconstructing the ancient environment, we can explore the specific impact of climate change on human beings and make due contributions to my country's future sustainable development strategy in the context of global warming. In the field of ice core research, there is little research on the subglacial layer, but some studies have shown that there are a large number of microorganisms in the ice-water interface layer. Therefore, the...
