Abstract

The invention relates to the technical field of deep sea detection, and particularly relates to a deep sea long-column-shaped sampler with an automatic valve closing mechanism. Thesampler comprises a sampling cylinder, wherein the bottom end of the sampling cylinder is sleeved with a fixed cylinder, an automatic valve closing assembly is inserted into the bottom end of the fixed cylinder, the automatic valve closing assembly comprises a valve cylinder, the valve cylinder is in screwed connection with the fixed cylinder, a partition plate is fixed in the valve cylinder, a liquid through hole is formed in the outer surface of the partition plate in a penetrating mode, a valve element assembly is movably connected in the sampling cylinder and comprises a first valve plate, a valve rod is integrally connected to the outer surface of the first valve plate, the end, which is away from the first valve plate, of the valve rod penetrates through the outer surface of the partition plate, the outer surface of the valve rod is sleeved with a second valve plate and a second limiting plate, and the second valve plate and the second limiting plate are arranged on the two sides of the partition plate. Automatic valve closing is achieved through the hydraulic difference value, the buoyancy difference can be changed, and recycling is facilitated.

Description

technical field [0001] The invention relates to the technical field of deep-sea detection, in particular to a long-column deep-sea sampler with an automatic valve closing mechanism. Background technique [0002] There are not only abundant fish resources in the ocean, but also resources such as liquefied natural gas and petroleum. The existence of such resources can be judged by analyzing the components of deep-sea soil and deep-sea water. [0003] Long columnar sampler is a kind of equipment for deep sea sampling. Its sampling part is columnar, so it is called long columnar sampler. According to the power used, it can be divided into gravity sampling tube, water spray sampling tube, shallow drill, vibrating piston sampler, and burst sampler. Sampling tube and hydraulic sampling tube, etc. [0004] In this regard, Chinese patent application number: 201810046730.3 discloses a sampler and a sampler, especially a columnar sediment sampler, including an upper end cover, a first...
