Embodiment Construction

[0050] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be noted that the following embodiments are intended to facilitate the understanding of the present invention, but do not limit it in any way.

[0051] figure 1 As an embodiment of the present invention, the deep-sea heat preservation biological sampler is composed of a cylindrical semiconductor refrigeration assembly 2 and an insulation cylinder 3. The two ends of the semiconductor refrigeration assembly 2 are respectively connected to two insulation cylinders 3 by flanges and bolts 4. The other port of the insulation cylinder 3 is opened or closed by the end cap 12 to form a closed space, constituting a sample chamber for collecting samples.

[0052]The end cap 12 is welded together with the end cap handle 13, and the end cap 12 is connected with the heat preservation tube 3 with a spring 11. On the insulation tube 3, a slider base 18...

Abstract

The invention, which relates to the technical field of deep sea sampling, discloses a deep sea thermal-insulation biological sampler comprising a heat preservation cylinder, a semiconductor refrigeration assembly, a temperature sensor, a controller, and a power source. The heat preservation cylinder has a cylindrical shape with two open ends; the opening at one end is opened or closed by an end cover. The semiconductor refrigeration assembly has a refrigeration function in an electrified sate and has a cylindrical shape with the two open ends; the two ends of the assembly are connected with the heat preservation cylinder respectively to form a sealed sampling chamber. The temperature sensor arranged in the sampling chamber is used for collecting the temperature in the sampling chamber andfeeding back the temperature to the controller. The controller adjusts the current flowing through the semiconductor refrigeration assembly according to the temperature change in the sampling chamber,thereby adjusting the refrigeration power of the semiconductor refrigeration assembly. The power source provides power for the semiconductor refrigeration assembly, the temperature sensor and the controller. According to the deep sea thermal-insulation biological sampler, the sample is refrigerated actively by using the semiconductor refrigeration piece, so that a phenomenon that the temperatureof the sample rises with the temperature rising of the sea water during the recycling process is avoided.

Description

technical field [0001] The invention relates to the technical field of deep sea sampling, in particular to a deep sea heat preservation biological sampler. Background technique [0002] Due to the rapid development of marine technology, humans have discovered that there are huge treasures in the deep sea. From a scientific point of view, mining marine biological resources helps to explore new species and life mechanisms; at the same time, marine organisms have potential economic value as ideal medicines and industrial material resources. Marine biological genetic resources have become one of the most intensely contested resource fields in the world. Obtaining high-quality deep-sea biological samples is an important content of modern oceanographic research. [0003] Seawater temperature generally decreases with increasing depth. The water surface temperature is about 25°C, and after passing through the thermocline where the temperature changes sharply, the temperature tends...
