[0034] The present invention will be described in more detail below in conjunction with the accompanying drawings. It should be noted that the description of the present invention with reference to the accompanying drawings is only illustrative and not restrictive. The various embodiments can be combined with each other to form other embodiments not shown in the following description.

[0035] See also Figure 1 and Figure 2 In one embodiment of the present invention, a new type of seabed base 100 is provided. The seabed base 100 has a simple structure and can always maintain a horizontal state during the deployment and landing process, and has good applicability.

[0036] The seabed base 100 includes: a base 10 , a plurality of flow guiding mechanisms 20 and an instrument floating mechanism 30 .

[0037] The base 10 includes: a bottom plate frame 11 and side plates 12 distributed circumferentially along the bottom plate frame 11. A plurality of first openings 111 are provided on the bottom plate frame 11 of the base 10. When the base 10 is in a state of being laid down and falling, external water can flow into the base 10 through the first openings 111. In addition, a accommodating cavity 13 for accommodating the instrument floating mechanism 30 is formed inside the base 10, that is, the accommodating cavity 13 is formed by the bottom plate frame 11 and the side plates 12 distributed circumferentially along the bottom plate frame 11, and the side of the accommodating cavity 13 facing away from the bottom plate frame 11 is connected to the external environment.

[0038] The base 10 is in a square cone shape. It is understood that the shape and size of the accommodating cavity 13 match the instrument floating mechanism 30, and the instrument floating mechanism 30 installed in the accommodating cavity 13 is in a closed state with the base 10; Figure 1As shown, based on the square cone-shaped configuration of the base 10, the overall configuration of the instrument floating mechanism 30 and the base 10 placed in the accommodating cavity 13 is also square cone-shaped, that is, the overall configuration of the seabed base 100 is streamlined and closed. When a bottom trawl passes through the seabed base 100, the trawl cannot hook the base 10 and the instrument floating mechanism 30. In addition, the overall streamlined configuration of the seabed base 100 can also reduce the pulling force of the trawl, thereby effectively improving the anti-trawl performance of the seabed base 100.

[0039] In addition, in order to further improve the anti-trawling capability of the seabed base 100, Figure 2 As shown, a plurality of lead counterweights 40 are arranged on the side of the bottom plate frame 11 of the base 10 facing the instrument floating mechanism 30, so as to further improve the anti-trawling performance of the seabed base 100 on the basis of increasing the deadweight of the base 10.

[0040] Among them, each guide mechanism 20 is installed one by one on each side plate 12 of the base 10, and each guide mechanism 20 located on the symmetrical two side plates 12 of the base 10 is symmetrically arranged. The water flowing into the interior of the base 10 through the first opening 111 will flow out through each guide mechanism 20 to achieve a drainage effect, and can also effectively reduce the water flow impact force received by the base 10 during the falling process, so that the base 10 always maintains a horizontal state during the falling process, thereby avoiding the seabed base 100 from tilting or flipping when it is laid and falling.

[0041] Please also read Figure 3 and Figure 4 As shown, the flow guide mechanism 20 includes at least one plate-like body 21, each of which is mounted on the side plate 12 of the base 10, and the plate-like body 21 can be turned over relative to the side plate 12, and each of the plate-like bodies 21 is arranged parallel to each other. It can be understood that when the base 10 is laid down, the external water flows into the inside of the base 10 through the first opening 111, and the plate-like body 21 turns over due to the impact of the water flow, that is, the plate-like body 21 turns outward under the impact of the water flow to form a through hole (not shown) between the plate-like body 21 and the corresponding side plate 12, so that the water in the base 10 flows out through the through hole formed between the plate-like body 21 and the corresponding side plate 12.

[0042] It should be noted that the flow guide mechanism 20 provided in this embodiment is not limited to the flow guide effect achieved by the flip design based on the plate-like body 21. Those skilled in the art can also achieve the flow guide effect by other types of structural settings, such as: a perforated plate with multiple through holes is installed on each side plate 12 of the base 10 for flow guide, or a grid mechanism formed by a plurality of grid plates intersecting each other is installed on each side plate 12 of the base 10 for flow guide, and the structures of the perforated plate and the grid mechanism are respectively as shown in FIG. Figure 5 , Figure 6 shown.

[0043] Among them, the diversion mechanism 20 also includes: one or more first rotating shafts 22, the number of the first rotating shafts 22 is the same as the number of the plate-like bodies 21, and each first rotating shaft 22 is correspondingly arranged on each plate-like body 21, and the first rotating shaft 22 is located on the side of the plate-like body 21 facing the inside of the base 10, that is, the first rotating shaft 22 is installed on the side of the plate-like body 21 facing the bottom plate frame 11, and the first rotating shaft 22 is horizontally arranged along the length direction of the plate-like body 21, and the two ends of the first rotating shaft 22 are fixedly installed on the side plate 12 of the base 10, so that the plate-like body 21 can be flipped with the length direction of the first rotating shaft 22 as the axis under the impact of the water flow.

[0044] It can be understood that a slot (not marked in the figure) connected to the first opening 111 is provided on the side plate 12 of the base 10, and the first rotation axis 22 passes through the plate-like body 21 in the horizontal direction and is fixedly mounted on the side plate 12. At the same time, the plate-like body 21 in the initial state can completely cover the slot, and the initial state refers to the state when the plate-like body 21 is not impacted by the water flow. When water flows into the base 10 through the first opening 111, the plate-like body 21 is impacted by the water flow and flips outward around the first rotation axis 22, so that the water flows out through the opening formed after the plate-like body 21 flips, thereby achieving a diversion effect.

[0045] Among them, the side of the plate-like body 21 facing the bottom plate frame 11 is connected to the bottom plate frame 11 through an elastic member (not shown in the figure), so that the force generated by the deformation of the elastic member can cause the plate-like body 21 to return to its initial state when it is not impacted by the water flow. It can be understood that when the plate-like body 21 automatically flips outward due to the impact of the water flow, the elastic member will be pulled to deform during the flipping process of the plate-like body 21. In addition, after the base 10 falls to the ground, the impact of the water flow on the plate-like body 21 disappears. At this time, the restoring force formed by the deformation of the elastic member will drive the plate-like body 21 to rotate inward around the first rotation axis 22, and finally restore the plate-like body 21 to its initial state. In addition, the elastic member is preferably a latex elastic rope.

[0046] Among them, a first limiting ring 211 is installed on the side of the plate-like body 21 facing the accommodating cavity 13, that is, the first limiting ring 211 is located on the side of the plate-like body 21 facing the bottom plate frame 11, and a second limiting ring 112 is installed on the side of the bottom plate frame 11 facing the plate-like body 21, and the first limiting ring 211 and the second limiting ring 112 are connected by an elastic member. It can be understood that one end of the elastic member is fixedly connected to the first limiting ring 211, and the other end is fixedly connected to the second limiting ring 112, so that the elastic member can be deformed during the flipping process of the plate-like body 21.

[0047] Please also read Figure 7 A limiting tube 212 is fixedly installed on the side of the plate-like body 21 facing the bottom plate frame 11, and the limiting tube 212 is rotatably sleeved on the axial outer side of the first rotating shaft 22, that is, the limiting tube 212 can be turned around the axial direction of the first rotating shaft 22 together with the plate-like body 21, and at the same time, a limiting groove 2121 is provided on the limiting tube 212; a convex portion 221 is formed at a position opposite to the first rotating shaft 22 and the limiting tube 212, and the convex portion 221 penetrates into the limiting groove 2121 and can rotate in the limiting groove 2121, that is, the limiting tube 212 and the first rotating shaft 22 are based on the limiting cooperation between the convex portion 221 and the limiting groove 2121 to limit the turning angle of the limiting tube 212, thereby achieving the effect of limiting the turning angle of the plate-like body 21 on the basis of limiting the turning angle of the limiting tube 212. It can be understood that the limiting cooperation between the protrusion 221 and the limiting groove 2121 can not only limit the flipping angle of the plate-like body 21, but also avoid the problem of the elastic member breaking due to the plate-like body 21 flipping outward at too large an angle, and further ensure that the plate-like body 21 automatically returns to its initial state under the action of the elastic member.

[0048] Among them, the instrument floating mechanism 30 installed in the accommodating cavity 13 can not only be fixedly installed in the accommodating cavity 13, but also can be separated from the base 10 and exist independently. At the same time, a cable is connected between the instrument floating mechanism 30 and the base 10, so that the staff can further salvage the base 10 after salvaging the instrument floating mechanism 30, thereby realizing the recovery of the seabed base 100.

[0049] Please also read Figure 8 and Fig. 9 The instrument floating mechanism 30 includes: a float 31, an instrument frame 32 and an automatic leveling mechanism 33. The instrument frame 32 is detachably installed in the accommodating cavity 13 formed inside the base 10. The float 31 is installed on the side of the instrument frame 32 facing away from the bottom plate frame 11. The automatic leveling mechanism 33 is installed on the side of the float 31 facing away from the instrument frame 32 and is connected to the instrument frame 32.

[0050] Among them, the material of the float 31 is preferably glass beads, so that the float 31 can not only provide the buoyancy required for the instrument frame 32 to rise, but also serve as a target reference for search during recovery. The instrument frame 32 can be installed with: Acoustic Doppler Current Profilers (ADCP), water temperature sensors, acoustic releasers, sound recorders and other self-contained observation instruments; in addition, the instrument frame 32 and the base 10 are preferably made of corrosion-resistant aluminum alloy to ensure the stability of the seabed base 100 in the seawater for a long time.

[0051] Please also read Fig.10 The automatic leveling mechanism 33 includes: a fixed platform 331, an outer ring body 332, a pair of second rotating shafts 333, an inner ring fixture 334 and a third rotating shaft 335. The details are as follows:

[0052] The fixed platform 331 is fixedly mounted on a side of the floating body 31 facing away from the instrument frame 32 and is arranged parallel to the bottom plate frame 11. At the same time, a second opening 3311 communicating with the instrument frame 32 is formed at the fixed platform 331.

[0053] The outer ring body 332 is disposed in the second opening 3311, and the outer ring body 332 and the fixed platform 331 are connected via a pair of second rotating shafts 333, each of which is symmetrically mounted at both radial ends of the outer ring body 332, and one end of each of the second rotating shafts 333 away from the outer ring body 332 can be rotatably mounted on a side of the fixed platform 331 facing the outer ring body 332, that is, the outer ring body 332 can be rotated relative to the fixed platform 331 based on the pair of second rotating shafts 333;

[0054] The inner ring clamp 334 is located on the inner side of the outer ring body 332 and is concentrically arranged with the outer ring body 332. The inner ring clamp 334 is used to clamp instruments and equipment, such as an acoustic Doppler flow profiler. The inner ring clamp 334 and the outer ring body 332 are connected by a pair of third rotating shafts 335. Each third rotating shaft 335 is symmetrically installed at the radial ends of the inner ring clamp 334. One end of each third rotating shaft 335 away from the inner ring clamp 334 can be rotatably installed on the side of the outer ring body 332 facing away from the fixed platform 331, so that the inner ring clamp 334 can achieve the effect of rotating relative to the outer ring body 332 based on the pair of third rotating shafts 335. In addition, the third rotating shaft 335 and the second rotating shaft 333 are arranged perpendicular to each other.

[0055] It can be understood that when the base 10 lands on the ground, the acoustic Doppler current profile can achieve an automatic leveling effect based on the cooperation between a pair of second rotating shafts 333, a pair of third rotating shafts 335 and the deadweight of the acoustic Doppler current profiler, thereby avoiding the problem of inaccurate observation data caused by the uneven seabed where the base 10 is located when it lands on the ground.

[0056] In addition, the instrument floating mechanism 30 also includes a seal 34, which is fixedly mounted on the side of the fixed platform 331 facing away from the bottom plate frame 11 and is used to seal the second opening 3311 to prevent the acoustic Doppler current profiler clamped by the inner ring clamp 334 from being exposed to seawater.

[0057] The working process of the seabed base 100 provided in the above embodiment can be described in detail as follows:

[0058] The staff laid the seabed base 100 and dropped it into the seawater. The seabed base 100 fell due to its own gravity. During the falling process, the water under the base 10 entered the bottom through the first opening 111 and impacted each plate-like body 21. Each plate-like body 21 flipped outward around the first rotation axis 22 under the impact of the water flow. At this time, a passage for water to flow out was formed between the plate-like body 21 and the side plate 12. The water that flowed in through the first opening 111 flowed out through the passage. In addition, when the plate-like body 21 flipped outward, the elastic member was gradually stretched and in a tensioned state as the plate-like body 21 flipped.

[0059] It can be understood that after the base 10 of the seabed foundation 100 falls to the ground, the side of the plate-like body 21 facing the ground frame is not affected by the impact of the water flow, so the plate-like body 21 can be pulled by the deformation force of the elastic member to rotate around the axial direction of the first rotating shaft 22, and finally the plate-like body 21 returns to its initial state.

[0060] In addition, the recovery process of the seabed base 100 provided in the above embodiment can be described as follows: the staff can remotely control the control end of the acoustic releaser to send a release signal to enable the acoustic releaser to release the instrument frame 32, that is, the acoustic releaser controls the instrument frame 32 to separate from the base 10; then, the buoyancy generated by the float 31 in the seawater will drive the instrument frame 32 to float to the water surface; finally, the staff salvages the float 31 and the instrument frame 32, and pulls the base 10 through the cable connecting the instrument frame 32 and the base 10 to achieve the recovery of the base 10, thereby achieving the purpose of recycling and reusing the seabed base 10 as a whole.

[0061] The seabed base 100 provided in the above embodiment has several first openings 111 opened at the bottom plate frame 11 of the base 10, and a diversion mechanism 20 is provided one by one at each side plate 12 of the base 10, so that during the process of laying and falling, water enters the base 10 through the first openings 111 and flows out through the diversion mechanism 20, which can avoid the base 10 from being unbalanced due to water flow impact or too fast falling speed, and can also effectively ensure that the seabed base 100 is always in a horizontal state during the falling process. In addition, the overall structure of the seabed base 100 in the present invention is a streamlined closed setting, which can effectively improve its anti-trawling performance and has good applicability.

[0062] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
