Embodiment Construction
[0036] The specific embodiment of the present invention will be described in further detail by describing the embodiments below with reference to the accompanying drawings, the purpose is to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and To facilitate its practice, but not as a limitation of the invention.
[0037] refer to figure 1 , a marine geological environment exploration sampler, including a casing 1, a multi-station sampling mechanism 2, a sealing mechanism 3 and a sampling stabilization mechanism 4. The sampler provided by the present invention is connected with the cable like the existing marine geological exploration sampler. When carrying out exploration and sampling of the seabed sediment layer, the ship sails to the position of the sea area to be explored, and then the sampler is released to the seabed by releasing the cable. Of course, the cable elec...

The invention relates to the technical field of exploration and sampling, and specifically provides a marine geological environment exploration sampler and a sampling method. The sampler includes a casing, a multi-station sampling mechanism, a sealing mechanism and a sampling stabilization mechanism; the casing includes a transmission box body, heat preservation cylinder and multiple keyway guide sleeves; the multi-station sampling mechanism includes multiple sampling cylinders for synchronous sampling; The number of side wing guide rails with the same number of sampling cylinders and a plurality of sliding sealing plates that are slidably assembled on the plurality of side wing guide rails; the sampler provided by the present invention enhances the stability and balance in the sampling process, and can form The insulation of the water area and the prevention of sample loss and disturbance by blocking the sample ensure the authenticity of the distribution of the sample and the validity of the sample.
Description
technical field [0001] The invention relates to the technical field of exploration and sampling, and specifically provides a marine geological environment exploration sampler and a sampling method. Background technique [0002] Whether it is the research of marine stratigraphy and paleoceanography, or the utilization and development of the marine geological environment, sampling the geological environment of the selected marine area, especially the sampling of the seabed sediments is naturally essential Exploration methods. In order to improve the reliability and accuracy of sediment sample analysis, it is of course necessary to eliminate external influence factors to the greatest extent so as to ensure that the sample after sampling can maintain the distribution form and state before sampling as much as possible. Sampling basically adopts gravity sampler or box sampler for sampling, but the existing sampling devices still have the problems of poor balance, poor stability, ...
