Problems solved by technology

At present, when sampling, the staff usually sets the target position in advance on the sampling ship and then sinks the grab into the water to grab samples. This method is easily affected by ocean currents, such as grabbing when lowering the grab The bucket will be impacted by the ocean current, which will affect its normal lowering; after the grab bucket sinks into the seabed, the hydraulic system in the bucket will fail due to the chan

Abstract

The invention discloses a self-propelled marine visual grab and a sampling ship thereof. The self-propelled marine visible grab includes a grab installation main body and two grabs symmetrically hinged at the lower part of the grab installation main body. A submersible propeller propeller is arranged horizontally on the wall, and a circumferential propeller propeller is vertically provided on the four side edges of the airtight cabin. The buoyancy adjustment device, the pressure compensation device, and the grab opening are arranged in the airtight cabin. Grab hydraulic system connected with closed hydraulic cylinder. The self-propelled marine visual grab and its sampling ship, the signals collected by the camera and deep-sea sensors are transmitted to the control room through the armored cable, so that the staff can first observe and detect the sampling area, and the computer control system and operation The adjustment of personnel can adjust the position and attitude of the grab, improve the ability of the device to resist the impact of ocean currents, and improve the stability and reliability of the grab.

Description

Technical field: [0001] The invention belongs to the field of deep sea sampling equipment, in particular to a self-propelled ocean visual grab and a sampling ship thereof. Background technique: [0002] With the continuous advancement of science and technology, people's exploration and research on the sea is also advancing. Among them, deep-sea sampling and marine scientific research including ore, seabed soil, seabed combustible ice and other seabed sediments require the use of scientific research ships to take samples to the sea surface. At present, when sampling, the staff usually set the target position in advance on the sampling ship and then sink the grab into the water to grab samples. This method is easily affected by ocean currents, such as grabbing when lowering the grab. The bucket will be impacted by the ocean current, which will affect its normal lowering; after the grab bucket sinks into the seabed, the hydraulic system in the bucket will fail due to the chang...
