Deep-sea anchor-system subsurface-buoy system based on satellite communication data real-time transmission

Abstract

The invention discloses a deep-sea anchor-system subsurface-buoy system based on satellite communication data real-time transmission. The deep-sea anchor-system subsurface-buoy system comprises a water-surface buoy system, a vertically-arranged plastic covered steel cable, a secondary floating body, an anchoring mooring part, a releasing unit, a primary floating body and a plurality of glass floating balls, and the deep-sea anchor-system subsurface-buoy system also comprises a frame body arranged between the main floating body and the releasing unit and used for carrying deepwater measuring apparatuses; a lifting adjusting mechanism for driving all the deepwater measuring apparatuses to move up and down along the plastic covered steel cable to measure measurement data of sections at different water-depth portions is arranged on the frame body. Through the lifting adjusting mechanism, continuous data monitoring of underwater preset depth distance sections can be achieved, and the void that continuous collection of section information under all temperature-salinit deepwater in different water depths cannot be carried out at present is filled; automatic control is achieved through a controller, the structure is reasonable, and running is stable; through an arranged lifting-adjusting auxiliary part, the resistance of the frame body in the ascending or descending process along the plastic covered steel cable is smaller, and running is more stable.

Description

technical field [0001] The invention relates to the technical field of ocean observation equipment, in particular to a deep sea mooring submersible buoy system based on real-time transmission of satellite communication data. Background technique [0002] Submersible buoy technology was used and developed by some marine developed countries in the 1960s; a system for long-term observation of marine environmental elements moored below the sea surface, and an acoustic release device can be recovered from the sea surface according to instructions. The buoy and submersible buoy system is an important technical equipment for marine environmental investigation. It has the characteristics of unattended long-term, continuous, synchronous and automatic comprehensive monitoring of various elements of marine hydrology and meteorology under harsh marine environmental conditions. The spatial and temporal expansion of marine observation shore stations, survey ships and survey aircraft is an...

Problems solved by technology

However, in the field of deep-sea marine monitoring, the instruments for detecting different water depths through submerged buoys are basically fixed, that is to say, ADCP and TD are generally set at a water depth of about 300-500 meters, and CTD and RCM are generally set at a water depth of about 800-1000 meters. In addition, an inductively coupled temperature-salt chain is installed about 50 to 100 meters below the water surface to monitor the profile measurement of seawater temperature, salinity, circulation, echo intensity and other marine environmental parameters at each depth. After the deployment is completed, data can only be collected for seawater information at a specific depth. At present, the total length of the submersible buoy is thousands of meters or even several kilometers, and once the deployment is completed, it cannot be adjusted arbitrarily.

Therefore, the acquired data is limited, and ocean data collection at different water depths cannot be realized. Moreover, since the system is deployed underwater and integrates multiple precious measuring instruments, whether it can be recovered reliably becomes a key factor when the submersible buoy system is deployed. Top Questions to Consider

The traditional method uses submersible buoy positioning, which can ensure the smooth recovery of the submersible buoy system. However, due to the complex and harsh seabed environment, there are many uncertain factors. Once the monitoring chain floats, once it becomes entangled, it will not only make it more difficult to salvage and recover, but also easily damage the measuring instruments on the cable

At present, the acoustic response releaser is used to realize the recovery of the submersible buoy, but the anchor chain, gravity anchor, grasping anchor and other components connected below the releaser cannot be recovered, resulting in waste
