Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0022] Example 1

[0023] like Figure 1 As shown:

[0024] A liftable fin with moon pool function comprises a moon pool compartment 1.

[0025] In this embodiment: the existing {public announcement number}: CN209600739U discloses a ship moon pool operating platform; in order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "the device may swing with the swaying of the ship during the hoisting of the scientific research instrument 10, thereby colliding with the fin shaft structure, and then causing damage to the instrument, affecting the normal investigation work", in terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve the above problems, the fin body 2 and the positioning ring 3 are added on this basis.

[0026] More specifically:

[0027] like Figure 1 - Figure 4 As shown:

[0028] In combination with the above content: it also includes a fin body 2, a positioning ring 3, a positioning piece 4, a slide rod 5, a connecting ring 6, a spring 7, a positioning seat 8, a positioning cone 9 and a scientific research instrument 10 arranged on one side of the moon pool warehouse 1. The inner surface of the moon pool warehouse 1 is slidingly connected to the fin body 2, and the inner surface of the fin body 2 is also fixedly installed with a positioning ring 3 that is fitted and connected to the positioning piece 4, and the surface of the positioning piece 4 is also slidingly connected to the slide rod 5. At the same time, the other end of the slide rod 5 is fixedly connected to the surface of the connecting ring 6, and the surface of the connecting ring 6 is also fixedly connected to one end of the spring 7, and the other end of the spring 7 is fixedly connected to the surface of the positioning piece 4, and the surface of the positioning piece 4 is also integrally formed with a positioning seat 8, and the positioning seat 8 is fitted and connected to the positioning cone 9 away from the positioning piece 4, and the positioning cone 9 is fixedly installed on the surface of the scientific research instrument 10.

[0029] In this embodiment: when it is necessary to perform detection work through the scientific research instrument 10, the fin body 2 and the positioning cone 9 can be hoisted along the inside of the moon pool 1 by the hoisting winch. When the positioning piece 4 reaches the position of the positioning ring 3, during this process, the hoisting winch and the fin body 2 are jointly controlled by the PLC program to achieve synchronous movement, and the positioning cone 9 and the positioning seat 8 are tightly fitted, which can avoid the scientific research instrument 10 and the moon pool 1 or the fin body 2 from colliding. When the positioning ring 3 and the positioning piece 4 are fitted, the positioning cone 9 and the positioning seat 8 are separated, and the scientific research instrument 10 and the positioning cone 9 continue to go deeper underwater for detection work. When the detection work is completed, the positioning cone 9 and the scientific research instrument 10 will return to the position of the positioning seat 8 under the action of the hoisting winch, and form a stable connection with the positioning seat 8. The hoisting winch can then be controlled to recover the scientific research instrument 10.

[0030] Going further:

[0031] In an optional embodiment, the diameter of the positioning ring 3 is smaller than the diameter of the positioning piece 4 .

[0032] In this embodiment: the positioning ring 3 which is smaller than the diameter of the positioning piece 4 can prevent the positioning piece 4 from entering the water along with the scientific research instrument 10 and the positioning cone 9 during the placement work, and when it is recovered, it can be returned to the position of the positioning piece 4 through the positioning cone 9 and the positioning seat 8.

[0033] Going further:

[0034] In an optional embodiment, circular through holes are formed at equal angles on the surface of the positioning piece 4 .

[0035] In this embodiment, the through holes on the surface of the positioning piece 4 enable the slide bar 5 to slide along the holes on its surface when performing a buffering effect, thereby enabling the spring 7 to effectively contract, thereby achieving a stable buffering effect.

[0036] Going further:

[0037] In an optional embodiment, the sliding rod 5 is cylindrical in shape, and the sliding rod 5 and the spring 7 are arranged at equal angles on the surface of the positioning piece 4 .

[0038] In this embodiment: the cylindrical slide rod 5 can make the spring 7 stably sleeved on its surface, and the spring 7 and slide rod 5 arranged at equal angles can provide stable buffering effect at all angles of the scientific research instrument 10.

[0039] Going further:

[0040] In an optional embodiment, the connecting ring 6 is in the shape of a circular ring.

[0041] In this embodiment, the annular connecting ring 6 can form a stable connection with the surface of the scientific research instrument 10, and can also provide a stable fulcrum for the slide rod 5 and the spring 7, so that the buffering effect of the spring 7 can be effectively carried out.

[0042] Going further:

[0043] In an optional embodiment, the shapes of the positioning seat 8 and the positioning cone 9 match, and the positioning cone 9 is conical in shape, and through holes are formed on the surfaces of the positioning seat 8 and the positioning cone 9 .

[0044] In this embodiment: the conical positioning cone 9 can form a stable connection with the positioning seat 8, thereby enabling effective positioning between the scientific research instrument 10 and the positioning piece 4, and making the placement and recovery of the scientific research instrument 10 more stable.

[0045] The working principle and usage process of the present invention are as follows: when it is necessary to perform detection work through the scientific research instrument 10, the fin body 2 and the positioning cone 9 can be hoisted along the inside of the moon pool 1 by the hoisting winch. When the positioning piece 4 reaches the position of the positioning ring 3, during this process, the hoisting winch and the fin body 2 are jointly controlled by the PLC program to achieve synchronous movement, and the positioning cone 9 and the positioning seat 8 are tightly fitted, which can avoid the scientific research instrument 10 and the moon pool 1 or the fin body 2 from colliding. When the positioning ring 3 and the positioning piece 4 are fitted, the positioning cone 9 and the positioning seat 8 are separated, and the scientific research instrument 10 and the positioning cone 9 continue to go deeper underwater for detection work. When the detection work is completed, the positioning cone 9 and the scientific research instrument 10 will return to the position of the positioning seat 8 under the action of the hoisting winch, and form a stable connection with the positioning seat 8. The hoisting winch can then be controlled to recover the scientific research instrument 10.
