If the frequency of the lifting hook 34 is too fast, the rotating shaft 341 at the top of the lifting hook 34 may contact the bottom end of the buffer column 33, the rubber blocks 343 disposed on the opposite end surfaces of the lifting hook 34 may play a role in buffering while contacting each other, and the uneven surface of the rubber blocks 343 may consume a large amount of energy during the friction process, thereby further improving the anti-swing effect. In addition, the support main plate 331 may push the buffer post 33 to move upward and compress the buffer spring 332 due to a sloshing or vibration from below, thereby further consuming a sloshing energy in the process of the movement of the buffer post 33 and the compression deformation of the buffer spring 332 and improving stability.

Therefore, the ocean scientific investigation equipment oscillation stopping recovery device can realize the omnidirectional oscillation stopping effect from top to bottom from the lifting assembly 20, the counterweight assembly 40 to the suspension assembly 30, improves the stability of the scientific investigation detection assembly 102 in the releasing and recovering processes, has a simple structure, is easy to operate, and is suitable for popularization and application.

Example 2

Fig. 8 and 9 schematically show an anti-sloshing recovery device for marine scientific research equipment according to another embodiment of the invention, which is different from example 1 in that:

in the weight assembly 40, the weight base 44 is hollow and is formed by hinging the weight side bodies 441 of two half-cylinder structures. A hole 442 is formed in the center of the bottom of the weight substrate 44, and a plurality of air guiding openings 443 are circumferentially arranged around the hole 442; an opening 444 is formed in the side wall of the counterweight base 44, an air guide pipe 445 is connected to the opening 444, one end, far away from the opening 444, of the air guide pipe 445 extends downwards through the air guide opening 443 until the end penetrates through the through hole 431 in the discus 43, and the anchor rope 103 penetrates through the hole 442 in the bottom of the counterweight base 44.

The counterweight base body 44 is hollow, but a counterweight column sleeve 41 is arranged below the counterweight base body, and a discus 43 is placed in the counterweight column sleeve 41, so that the gravity center of the counterweight assembly 40 can be arranged at the bottom of the counterweight base body 44, and the stability of the gravity center is further improved. The air guide pipe 445 fills the interior of the counterweight base 44, so that the anchor rope 103 is prevented from shaking in the interior of the hollow counterweight base 44 or the shaking space of the anchor rope 103 is reduced, and the stability is improved. The air guide pipe 445 extends to the discus 43 inside the weight post sleeve 41 and can be used for filling the gap between the anchor rope 103 and the through hole 431 of the discus 43, thereby reducing the friction contact frequency between the anchor rope 103 and the discus 43 and reducing the sloshing space of the anchor rope 103. In addition, the wind guide pipe 445 can guide the wind flow on the side surface of the counterweight base body 44 downwards, namely, the flow direction of the wind is changed to reduce the influence of the wind on the counterweight assembly 40, so that the stability of the counterweight base body 44 can be improved, the frequency of the counterweight base body 44 swinging along with the wind flow is reduced, the downward pressure can be formed by the wind flowing along the wind guide pipe 445, the verticality of the anchor rope 103 is further improved, the swinging of the rope body 25 is reduced, the influence on the scientific investigation detection assembly 102 is reduced, and the stability is improved.

The embodiments described above are intended to illustrate the technical solutions of the present invention in detail, and it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modification, supplement or similar substitution made within the scope of the principles of the present invention should be included in the protection scope of the present invention.
