The various embodiments may be combined with each other to form other embodiments not shown in the following description.

Referring to fig. 1 and 2, in an embodiment of the present invention, a novel seabed base 100 is provided, and the seabed base 100 has a simple structure, can be kept in a horizontal state all the time during the laying and falling process, and has a good applicability.

The seabed base 100 comprises: a base 10, a plurality of diversion mechanisms 20 and an instrument floating mechanism 30.

Wherein, this base 10 includes: the base comprises a bottom plate frame 11 and side plates 12 distributed along the circumferential direction of the bottom plate frame 11, wherein the bottom plate frame 11 of the base 10 is provided with a plurality of first openings 111, and when the base 10 is in a laying and falling state, external water can flow into the base 10 through the first openings 111; in addition, a housing chamber 13 for housing the instrument floating mechanism 30 is formed inside the base 10, that is: the accommodating cavity 13 is formed by mutually enclosing a bottom plate frame 11 and side plates 12 distributed along the circumferential direction of the bottom plate frame 11, and one side of the accommodating cavity 13 back to the bottom plate frame 11 is communicated with the external environment.

Wherein, the shape of the base 10 is square and cone-shaped. It can be understood that the shape and size of the accommodating cavity 13 are matched with those of the instrument floating mechanism 30, and the instrument floating mechanism 30 arranged in the accommodating cavity 13 is in a closed state with the base 10; as shown in fig. 1, on the basis that the shape of the base 10 is a square cone-shaped configuration, the instrument floating mechanism 30 disposed in the accommodating cavity 13 and the whole shape of the base 10 are also square cone-shaped configurations, that is, the whole shape of the seabed base 100 is a streamline closed configuration, when the submerged trawl passes through the seabed base 100, the trawl cannot hook the base 10 and the instrument floating mechanism 30, and the whole shape of the seabed base 100 is a streamline configuration, so that the pulling force of the trawl can be reduced, and the trawl resistance of the seabed base 100 is effectively improved.

In addition, in order to further improve the trawl resistance of the seabed 100, as shown in fig. 2, a plurality of weight-balancing lead blocks 40 are disposed 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 trawl resistance of the seabed 100 on the basis of increasing the self weight of the base 10.

Wherein, each water conservancy diversion mechanism 20 one-to-one is installed on each curb plate 12 of base 10, be located symmetrical setting between each water conservancy diversion mechanism 20 on the symmetrical both sides board 12 of base 10, the water that flows into to base 10 inside via first opening 111 will flow out via each water conservancy diversion mechanism 20, in order to reach the drainage effect, also can effectively reduce the rivers impulsive force that base 10 whereabouts in-process received, and then make base 10 remain the horizontality all the time at the in-process that falls, thereby avoid seabed base 100 to appear slope or turn-buckle phenomenon when laying the whereabouts.

Referring to fig. 3 and 4, the air guiding mechanism 20 includes at least one plate 21, each plate 21 is mounted on the side plate 12 of the base 10, the plate 21 can be turned over relative to the side plate 12, and the plates 21 are parallel to each other. It can be understood that when the base 10 is laid down, external water flows into the base 10 through the first opening 111, the plate-shaped body 21 is turned over by water flow impact, that is, the plate-shaped body 21 is turned towards the outside under the action of the water flow impact to form a through opening (not shown) between the plate-shaped body 21 and the corresponding side plate 12, so that the water in the base 10 flows out through the through opening formed between the plate-shaped body 21 and the corresponding side plate 12.

It should be noted that the flow guiding mechanism 20 provided in the present embodiment is not limited to achieve the flow guiding effect based on the inverted design of the plate-shaped body 21, and those skilled in the art can achieve the flow guiding effect through other types of structural arrangements, such as: each side plate 12 of the base 10 is provided with a perforated plate having a plurality of through holes for guiding flow, or each side plate 12 of the base 10 is provided with a grating mechanism formed by a plurality of grating plates crossing each other for guiding flow, and the structures of the perforated plate and the grating mechanism are respectively shown in fig. 5 and 6.

Wherein, water conservancy diversion mechanism 20 still includes: one or more than two first rotating shafts 22, the number of the first rotating shafts 22 is the same as that of the plate-shaped bodies 21, the first rotating shafts 22 are correspondingly arranged on the plate-shaped bodies 21 in a penetrating manner, the first rotating shafts 22 are positioned on one sides of the plate-shaped bodies 21 facing the inside of the base 10, namely, the first rotating shafts 22 are arranged on one sides of the plate-shaped bodies 21 facing the bottom plate frame 11, the first rotating shafts 22 are horizontally arranged along the length direction of the plate-shaped bodies 21, and two end parts of the first rotating shafts 22 are fixedly arranged on the side plates 12 of the base 10, so that the plate-shaped bodies 21 can be overturned by taking the length direction of the first rotating shafts 22 as an axis under the impact action.

It can be understood that a notch (not shown) communicating with the first opening 111 is formed on the side plate 12 of the base 10, the first rotating shaft 22 passes through the plate-shaped body 21 in the horizontal direction and is fixedly mounted on the side plate 12, and meanwhile, the plate-shaped body 21 in the initial state can completely cover the notch, the initial state is a state when the plate-shaped body 21 is not impacted by water flow. When water flows into the base 10 through the first opening 111, the plate-shaped body 21 is turned outwards around the first rotation axis 22 due to the impact of the water flow, so that the water flows out through the through hole formed after the plate-shaped body 21 is turned, thereby achieving the flow guiding effect.

The side of the plate-shaped body 21 facing the bottom plate frame 11 is connected to the bottom plate frame 11 through an elastic member (not shown), so that the plate-shaped body 21 can return to an initial state when not impacted by water flow due to an acting force generated by deformation of the elastic member. It can be understood that, when the plate-shaped body 21 is turned towards the outside automatically under the action of water impact, the plate-shaped body 21 will be pulled to deform during the turning process, and in addition, the water impact action on the plate-shaped body 21 disappears after the base 10 falls to the ground, at this time, the restoring acting force formed based on the deformation of the elastic member will drive the plate-shaped body 21 to rotate towards the inside around the first rotating shaft 22, and finally the plate-shaped body 21 is restored to the initial state. In addition, the elastic member is preferably a latex elastic cord.

It can be understood that, the limit cooperation between the protrusion 221 and the limit groove 2121 can limit the turning angle of the plate-shaped body 21, and can also avoid the problem that the elastic member is broken due to an excessively large turning angle of the plate-shaped body 21 toward the outside, and further can ensure that the plate-shaped body 21 automatically returns to the initial state under the action of the elastic member.

Wherein, install in the instrument upward floating mechanism 30 that holds in cavity 13 not only can fixed mounting hold cavity 13 in, can also break away from base 10 and exist alone, simultaneously, be connected with the hawser between instrument upward floating mechanism 30 and the base 10 to the staff is fishing out instrument upward floating mechanism 30 after further salvage base 10, thereby realizes the recovery of seabed base 100.

Within the instrument frame 32 may be mounted: self-contained observation instruments such as an Acoustic Doppler Current Profiler (ADCP), a water temperature sensor, an Acoustic releaser and a sound recorder; in addition, the instrument frame 32 and the base 10 are preferably made of corrosion-resistant aluminum alloy, so as to ensure the stability of the seabed 100 in seawater for a long time.
