Problems solved by technology

[0004] In addition to the communication is easy to expose the position and be destroyed, leading to the loss of the submersible mark, there are many quality problems of the submersible mark components, such as the acoustic communication failure of the acoustic release device, the corrosion and fracture of the shackle, the breakage of the connecting cable after aging, the drift of the submersible mark, and the corrosion and fracture of the anchor chain, etc. All reasons may lead to the loss of submerged buoys, resulting in the inability to recover the observation data of faulty or lost submersible buoys

Abstract

The invention provides a subsurface buoy with a data recovery instrument. The subsurface buoy comprises a main floating ball, the data recovery instrument and a subsurface buoy controller connected with a controller in the data recovery instrument and arranged in the main floating ball. The data recovery instrument comprises a sealed cabin, a controller and a memory which are arranged in the sealed cabin, and a hollow floating body, and the sealed cabin is fixed to the floating body; a pressure sensor which is arranged above the sealed cabin and is connected with the controller; the release device comprises a first connecting part connected to the lower portion of the sealed cabin and a second connecting part arranged on the first connecting part in a sleeving mode; a connecting piece which is arranged in the first connecting part; a magnetic piece which is arranged in the first connecting part and abuts against the connecting piece; an electromagnet which is arranged in the first connecting part and is connected with the controller; a through hole is formed in the first connecting part, a clamping groove is formed in the second connecting part, and when the electromagnet is not electrified, the connecting piece extends out of the through hole and is clamped in the clamping groove; when powered on, the connecting piece is separated from the clamping groove. According to the subsurface buoy, the damaged or lost observation data of the subsurface buoy can be obtained.

Description

technical field [0001] The invention relates to a submersible buoy for ocean observation, in particular to a data recovery device for a submersible buoy and a submersible buoy including the data recovery device. Background technique [0002] The submersible buoy can realize the long-term continuous measurement of the marine elements at the location where the submerged buoy is placed, and is one of the important equipment that can conduct fixed-point continuous observation of the marine elements. For example, the CN201220748198.8 patent document discloses the basic structure of the 3500-meter submersible buoy: "It is formed in series by the following components: main buoy support, 50-meter kevlar rope, the first floating ball group, the first group of 1000-meter kevlar rope, the second Float group, the second group of 1000-meter kevlar rope, the third group of float ball, the third group of 1000-meter kevlar rope, the fourth group of float ball, the releaser group, and the mo...
