Description

Technical Field

[0001] The present invention belongs to the field of deep-sea observation equipment, and relates to a bottom-mounted long-term deep-sea environmental noise observation device that can be deployed by a submersible, mainly applicable to long-term observation of deep-sea environmental noise, long-term observation of acoustic signals of deep-sea geological activities, etc. Background Art

[0002] Special submarine geological activity areas such as hydrothermal vents and cold seeps are current hotspots in ocean research. There are sound sources such as hydrothermal flows, bubble flows, and benthic organisms in this area. These acoustic signals contain rich information on submarine geological activities and ecological activities. By collecting and analyzing the acoustic signals in the hydrothermal vent and cold seep areas, their activity levels can be directly reflected. The information contained in the acoustic signals is of great value for marine geophysical scientific research such as exploring their internal movement laws, evolution processes, and inferring deep activity mechanisms. Compared with marine observation platforms such as mooring systems and subsea buoys, the deep-sea acoustic long-term observation device based on a submersible has the advantage of accurate placement position, which helps to improve the detection accuracy.

Detailed Embodiment

[0028] The present invention will be further described below with reference to the drawings and embodiments.

[0029] The separation schematic diagram of the bottom-mounted long-term deep-sea environmental noise observation device is as Figure 1 shown, and the docking completed diagram of the bottom-mounted long-term deep-sea environmental noise observation device is as Figure 2As shown, the docking mechanism diagram of the bottom-mounted deep-sea ambient noise long-term observation device is as follows Figure 3 As shown, the present invention includes a deployment docking frame 1, a docking fixing oil cylinder 2, and a docking fixing column 3 as follows Figure 6 As shown, a docking guiding column 4 as follows Figure 5 As shown, a base fixing frame 5 as follows Figure 6 As shown, a deep-water hydrophone 6, a micro-miniature watertight double-headed cable 7, a micro-miniature watertight connector base 8, a battery compartment 9, an electronic compartment 10, a pressure-resistant compartment fixing bolt 11, and an oil cylinder fixing bolt 12. An installation hole for the docking fixing oil cylinder 12 is provided on the deployment docking frame 1, and the fixing oil cylinder 12 can be fixed to the deployment docking frame 1 with the oil cylinder fixing bolt 12. A threaded hole for installing the docking fixing column 3 and a threaded hole for installing the docking guiding rod 4 are provided at the top of the base fixing frame 5, and a through hole for fixing the pressure-resistant compartment is provided at the bottom. The docking fixing column 3 and the base fixing frame 5 are connected by threads, and the docking guiding column 4 and the base fixing frame 5 are connected by threads. The battery compartment 9, the electronic compartment 10, and the base fixing frame 5 are connected by bolts. A threaded hole is provided at the top of each battery compartment 9, and the micro-miniature watertight connector base 8 and the battery compartment are connected by threads. Two threaded holes are provided at the top of the electronic compartment 10 for threaded connection with the micro-miniature watertight connector base 8. The two-core end of the micro-miniature watertight double-headed cable is used to connect with the micro-miniature watertight connector 8 of the battery compartment 9, and the 12-core end is used to connect with the micro-miniature watertight connector 8 of the electronic compartment 10.

[0030] The working principle of the present invention is as follows:

[0031] As follows Figure 1 As shown, after the submersible carries the present invention close to the deep-sea target area, the extending rod of the docking fixing oil cylinder 2 retracts and disengages from the fixing hole of the docking fixing column 3. The bottom-mounted long-term noise observation device disengages from the deployment docking frame 1 and descends until it reaches the bottom and stops moving. The deep-water hydrophone 6 receives the deep-sea ambient noise signal, and the signal acquisition is completed by the data acquisition and recording equipment in the electronic compartment 10. Since it needs to work for a long time, the annular battery compartment 9 supplies power to the electronic compartment 10.

[0032] As follows Figure 2 As shown, the submersible carries the docking fixing frame 1 close to the present invention, and fits the guiding column hole on the docking fixing frame 1 with the guiding column 4 on the base fixing frame 5. When the deployment docking frame 1 and the base fixing frame 5 are in contact, the extending rod of the docking fixing oil cylinder 2 extends and connects with the installation hole of the docking fixing frame 3, thereby completing the docking of the bottom-mounted deep-sea ambient noise long-term observation device and the deployment docking frame 1. Next, it is carried by the submersible and floats up, leaving the target seabed area.

[0033] One application example of the present invention is as follows:

[0034] For long-term detection of the noise of submarine hydrothermal vents, the submersible carrying the present invention moves near the hydrothermal vents, the extending rod of the docking fixed oil cylinder 2 retracts, the bottom-mounted deep-sea ambient noise long-term observation device is separated from the deployment docking frame 1, and sinks to the surface of the seabed sediment. The deep-water hydrophone converts the deep-sea ambient noise signal into an electrical signal, and the data acquisition and storage device in the electronic cabin records the signal.

[0035] The implementation schemes in the above description can be further combined or replaced, and the implementation schemes are only descriptions of the preferred embodiments of the present invention, and do not limit the concept and scope of the present invention. Without departing from the design idea of the present invention, various changes and improvements made by those of ordinary skill in the art to the technical solutions of the present invention all belong to the protection scope of the present invention.
