Abstract

The invention discloses a marine environment information subsurface buoy device based on a multi-parameter sensor. The marine environment information subsurface buoy device mainly comprises a pressure-resistant floating ball, a measuring vertical array, a subsurface buoy system and an anchoring system which are sequentially connected from top to bottom. The measuring vertical array is formed by movably connecting a plurality of sub-sections for acquiring environmental information; a subsurface buoy module is arranged in the subsurface buoy system and used for synchronously storing and measuring data information output by the last subsection of the vertical array. The beneficial effects of the marine environment information subsurface buoy device are as follows: the requirements of design specifications for observing hydrological environment and marine environment noise in medium and shallow sea areas are met; and the device has the capabilities of marine environmental noise measurement, underwater acoustic signal measurement, seawater temperature measurement and seawater pressure measurement. An effective way is provided for measuring the hydrological environment and the marine environment noise level of the marine survey and measurement ship in the medium-shallow sea area, the marine environment noise measurement capacity, the underwater acoustic signal measurement capacity, the seawater temperature measurement capacity and the seawater pressure measurement capacity are enhanced, and the domestication technical level of applying marine instruments is improved.

Description

technical field

[0001] The invention relates to the field of marine environment information acquisition, in particular to a marine environment information submersible mark device based on a multi-parameter sensor. Background technique

[0002] Marine environmental noise is not only the background noise interference field of various marine acoustic systems, but also carries a large amount of useful marine environmental information. Therefore, the study of marine environmental noise is of great significance in both civil and military applications. In order to improve the performance of underwater acoustic detection equipment, it is necessary to fully investigate and analyze the characteristics of marine environmental noise, and deeply understand the characteristics of time domain, frequency domain and air domain of marine environmental noise, which requires continuous measurement of marine environmental noise. With the development of vibration reduction and noise reduction tec...

Examples

Embodiment 1

[0031] Embodiment 1: as attached figure 1 As shown, this marine environmental information submersible buoy device based on multi-parameter sensors includes a pressure-resistant buoy 1, a vertical measurement array 2, a submersible buoy system 3 and a mooring system 4 connected in sequence from top to bottom, wherein the pressure-resistant buoy The ball 1 and the measuring vertical array 2, the submersible buoy system 3 and the mooring system 4 are connected through a Kevlar cable 5.

[0032] as attached figure 2 As shown, it is a schematic diagram of the cross-view structure of the measurement vertical array 2 in this embodiment. The measurement vertical array 2 includes eight sections of movably connected measurement vertical array subsections for collecting environmental information. Connected head connector 21-1 and tail connector 21-2, tension rope 21-3 connecting head connector 21-1 and tail connector 21-2, multiple supports evenly distributed on the tension rope 21-3 ...

Embodiment 2

[0039] Embodiment 2: The difference from Embodiment 1 is that the vertical measuring array 2 has only 5 measuring subsections, and the insulating and waterproof sheath 21-5 is made of polyethylene terephthalate .

Embodiment 3

[0040] Embodiment 3: The difference from Embodiment 1 is that the measurement vertical array 2 has 15 measurement sub-sections in total. as attached Figure 7 As shown, the outer surface of the insulating and waterproof sheath 21-5 is covered with a streamer 21-10 braided with fine fibers, and the streamer 21-10 is used to change the vortex generated when the current water body passes through the measurement of the non-streamlined object on the surface of the vertical array 2, destroying The formation of eddies further reduces the vibration noise generated by the vortex laminar flow field, reduces the probability that the information collected by the receiving hydrophone 21-7 cannot truly restore the noise level of the marine environment, and improves the authenticity of the collected environmental noise signals; As a preference, the insulating and waterproof sheath 21-5 is made of polyethylene;

[0041] as attached Figure 8 As shown, the mooring system 4 also includes a pl...
