An ocean bottom sampling device

Abstract

The invention discloses an ocean submarine sampling device. The ocean submarine sampling device comprises a cylinder body, weight bearing blocks are arranged on the two sides of the cylinder body, a placement groove is arranged at the bottom of the weight bearing block, a spring is arranged in the placement groove, a sealing plate is arranged at one end of the spring, a shovel plate is arranged atone end of the sealing plate, a hollow cavity is arranged on the surface of the cylinder body, a first limiting block is arranged in the hollow cavity, a second limiting block is arranged at the topof the first limiting block, grooves are arranged on the two sides of the second limiting block, balls are arranged in the grooves, and a moving plate is arranged at the bottom of the second limitingblock. Through the arrangement of the spring and the sealing plate, the moving plate pushes upside when the cylinder body descends under the effect of the self-gravity of the weight bearing blocks andwhen the bottom of the moving plate touches the riverbed, the sealing plate moves in a through groove under the action of the spring, the two sealing plates support a sampling substance in the cylinder body, and the device is beneficial for saving the energy, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to the technical field of sampling devices, in particular to an ocean bottom sampling device. Background technique [0002] At present, most of the columnar samplers used for underwater sediment sampling are vibrating piston samplers. The vibrating piston sampler uses a bracket to make the sampling tube vertical to the seabed, and uses an electric drive to vibrate the vibrator to produce a vibration effect to obtain samples. In addition to the sampling cable, the vibrating piston sampler must have an additional bracket and a vibrator. The power supply cable is complex in design and bulky, and it is troublesome to use. At the same time, it is impossible to accurately sample a certain part during sampling. [0003] Therefore, it is necessary to invent a kind of ocean bottom sampling device to solve the above problems. Contents of the invention [0004] The object of the present invention is to provide a marine seabed sampling de...
