Seabed sediment collection device for marine organism research

Abstract

The invention discloses a seabed sediment collection device for marine organism research. The device comprises a battery box, an electric propeller, a storage battery and a conversion button, the electric propeller is mounted on the outer side of the battery box, the storage battery is arranged in the battery box, the conversion button is mounted on the lower surface of the battery box, a limitinggroove is formed in the surface of a mounting frame, a storage groove is formed in the lower end of a sampling barrel, a one-way valve plate is also mounted on the outer side of the storage groove, alimiting rod is mounted on a partition plate, and the limiting rod penetrates through the sampling barrel to be connected with the limiting groove. The seabed sediment collection device for marine organism research can automatically dive and sink through the electric propeller, and meanwhile, the pushing force of the electric propeller can push the lower end of the sampling barrel to be insertedinto a seabed to automatically extract submarine sediments, so that manual diving for manually extracting the sediments is avoided, the sediment extraction steps are simplified, and meanwhile, the harm to the personal health of related workers is avoided.

Description

technical field [0001] The invention relates to the technical field of marine biology research, in particular to a seabed sediment collection device for marine biology research. Background technique [0002] Bottom sediment sample collection is an important part of marine intertidal environment investigation. Sediment samples can be used for related coastal zone geology, ecological environment research and analysis and other activities. In order to obtain samples of marine biological sediments, it is usually necessary to To extract the biological sediment on the bed, the unit usually needs to use a sediment collection device, but the existing sediment collection device usually has the following problems in the process of use: [0003] 1. The traditional seabed sediment sampling and collection method is to manually carry the sampling cylinder to the seabed to manually extract the sediment. This extraction method is relatively cumbersome, and there is a certain probability of ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a seabed sediment collection device for marine biological research, to solve the traditional seabed sediment sampling collection method proposed in the above background technology is to manually carry the sampling cylinder to dive to the bottom of the sea to manually extract the sediment , this kind of extraction method is relatively cumbersome, and there is a certain probability of endangering the life safety of workers, and the risk is high. The traditional collection device is not conducive to the vertical extraction of seabed sediments, which will destroy the vertical structure of the sample. Also because of the large volume and weight, it is not suitable for use in the intertidal zone, which affects the normal extraction of sediments
