Embodiment 1

[0027] 1) Reference figure 1 Shown is the overall schematic diagram of the monitoring device. Install the upward acoustic Doppler velocity profiler 101, the downward acoustic Doppler velocity profiler 1012, the turbidity meter 102, the underwater camera 103, the natural potential probe rod 104, etc. to the recovery rack for the monitoring equipment required by the monitoring system At the lower part, each device has its own storage function to store all monitoring data in its own SD card, and the data processing will be performed after the device is recycled. In addition, before installation, it is necessary to set the normal parameters of each device according to the monitoring requirements. During the installation process, the weight is evenly distributed to keep the center of gravity of the recovery system at the center of the recovery rack. When installing the monitoring equipment, it is necessary to ensure that there are no other objects above and below that will affect t...

Abstract

The invention belongs to the technical field of long-term in-situ monitoring of deep sea surface mineral mining sediment disturbance, and relates to a deep sea polymetallic nodule mining sediment environment monitoring device. The monitoring system is provided with a Doppler current profiler, a natural potential feeler lever, a turbidimeter and an underwater camera. Long-term in-situ observation of sediment disturbance can be achieved, mechanical recovery of probe rod type equipment can be achieved, a large mechanical device is not needed, the overall weight of recovery equipment is reduced, and the probability of successful recovery of the equipment is increased. Compared with existing seabed long-term in-situ observation equipment, the device disclosed in the invention is more environmentally friendly, efficient, capable of saving energy and reliable.

Description

technical field [0001] The invention belongs to the technical field of long-term in-situ monitoring of deep-sea surface mineral mining sediment disturbance, and relates to a deep-sea polymetallic nodule mining sediment environment monitoring device. Background technique [0002] With the consumption of terrestrial resources, people have gradually turned their attention to the sea. 70% of the earth is covered by oceans, and 15% of the oceans are covered with polymetallic nodules. Polymetallic nodules exist on the surface of seabed sediments at depths of more than 4,500 meters. It is rich in resource reserves and is considered to be the deep-sea mineral resource with the most commercial mining value in the future. [0003] There are two main reasons why commercial mining has not yet been carried out: one is mining technology, and the other is environmental impact. Regarding the environmental impact monitoring of polymetallic nodule mining, in terms of the occurrence state o...
