Problems solved by technology

[0003] For the locking and releasing of large and heavy loads, the principle of toothed snap ring is usually used for design. The snap ring is generally driven by the oil cylinder. When the oil cylinder fails, it will easily lead to the failure of the locking and releasing operation, thus affecting the performance of key functions.

Embodiment Construction

[0037] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0038] Such as Figure 1-Figure 7 As shown, the double-acting unlocking mechanism suitable for underwater equipment in this embodiment includes an upper flange 101 and a lower flange 103, and a locking ring with a toothed structure is passed between the upper flange 101 and the lower flange 103. 102 connection, after the locking ring 102 rotates the angle, the locking and disengagement of the upper flange 101 and the lower flange 103 are realized, and the upper flange 101 and the lower flange 103 are respectively connected to the target;

[0039] Two translation unlocking units 107 are symmetrically arranged on the inner wall surface of the locking ring 102,

[0040] A rotation unlocking unit 104 is also installed on the inner wall of the locking ring 102;

[0041] The translation unlocking unit 107 and the rotation unlocking unit 104 ar...

Abstract

The invention discloses a double-acting unlocking mechanism suitable for underwater equipment. The mechanism comprises an upper flange and a lower flange, the upper flange and the lower flange are connected through a locking ring of a tooth meshing type structure, after the locking ring rotates by an angle, locking and disengaging work of the upper flange and the lower flange is achieved, and the upper flange and the lower flange are separately connected with target objects; two translation unlocking units are symmetrically arranged on the inner wall face of the locking ring, and a rotation unlocking unit is further installed on the inner wall face of the locking ring; and the translation unlocking units and the rotation unlocking unit are mutually independent. Through mutual cooperation of a translation unlocking mechanism and a rotation unlocking mechanism, the two sets of unlocking units which adopt different principles and independently operate are adopted, each set of unlocking unit has the capacity of unscrewing the locking ring, and anti-interference design is adopted, so that mutual retardation in the operation process is avoided, the working resistance is reduced, and the unlocking reliability is improved.

Description

technical field [0001] The invention relates to the technical field of unlocking mechanisms, in particular to a double-acting unlocking mechanism suitable for underwater equipment and an unlocking method thereof. Background technique [0002] The ocean world is rich in resources, and it is the most realistic and most potential strategic space for human beings. In recent decades, human exploration of the ocean has continued to deepen. As the key equipment for marine operations, deep-sea manned equipment can carry scientists and engineers into the deep sea to effectively carry out marine investigation, detection, sampling and other operations. Deep-sea manned equipment is a large and complex system with various operation forms and high functional requirements. The locking and releasing function is one of the key requirements of deep-sea manned equipment. Locking and releasing technology is also an important common technology in the field of deep-sea equipment. It requires fir...
