Description

a sea bed

technical field

The invention relates to the field of marine surveying instruments, in particular to a seabed base.

Background technique

The measurement of marine environmental profile parameters is mostly carried out by shipborne sensors or sensor groups laid in layers by submerged markers. These two types of traditional measurement methods are generally considered insufficient in terms of space and time for the increasingly demanding ocean observations, or their cost is too high—the ship-borne instruments cooperate with the winch to complete multiple trips Measurement, even for several days of continuous observation, will consume a lot of manpower and financial resources; using traditional submerged mark measurement, it is necessary to lay multiple sensors in layers, which not only greatly increases the cost of equipment, but also inevitably leads to complex mooring systems, and its on-site operation The difficulty also increases accordingly. In addition to the corresponding equipment costs, damage to the equipment due to factors such as harsh sea conditions and fishing boat trawls must also be considered.

Recently, a tethered lifting platform that can move vertically up and down along the mooring cable has also appeared, which can realize fixed-point vertical profile observation and provide long-term fixed-point vertical profile marine environmental parameters. For example, the application number is 201810747874.1 Chinese invention patent application . However, due to frequent fishing activities in my country's coastal waters, the moored platforms deployed are mostly damaged by fishing boat trawls, resulting in equipment damage or even loss, resulting in that this technology cannot be well applied in my country's coastal waters. At the same time, due to the large number of marine fishing activities in my country's coastal waters, the mobile platform also has the risk of being damaged by fishing boat trawls.
