A steering switch cover mechanism for a deep-sea heat preservation and pressure holding cabin

Abstract

The invention relates to deep sea and ocean bottom sampling and transfer equipment, specifically a steering switch cover mechanism of a deep sea thermal insulation and pressure maintaining cabin. The power source and the steering rod fixing frame are respectively installed on the thermal insulation and pressure maintaining cabin body, and the steering rod can move relatively. And inserted into the steering rod fixed frame, one end is connected to the output end of the power source through the rotating mechanism, the other end is connected to the top cover fixed frame, the other end of the top cover fixed frame is connected to the top cover; the steering rod is provided along the axial direction There is a motion track groove, and the steering rod fixed frame is provided with a pin inserted in the motion track groove. The steering rod is driven by the power source to reciprocate in the axial direction. The pin is always located in the motion track groove during the lifting process. Realize the switch cover between the top cover and the thermal insulation and pressure maintaining cabin body. The invention can complete the function of non-directional rotation under the condition that a single oil cylinder power source is supplied, reduces the control quantity of multiple input and output of the power source, avoids high-precision collaborative operations, and reduces the probability of errors.

Description

technical field [0001] The invention relates to deep-sea seabed sampling and transshipment equipment, in particular to a steering switch cover mechanism for a deep-sea heat preservation and pressure holding cabin. Background technique [0002] At present, the opening and closing lid movement modes of the few deep-sea thermal insulation and pressure holding sample transfer chambers currently in use generally have three movement modes. The first one is to open and close the lid through uniaxial reciprocating motion of the oil cylinder under the condition of sufficient height space; the characteristic of this reciprocating motion mechanism is that the movement space is large and the axial direction is single. The second type, under the condition of sufficient power source input and output units, can use double cylinders to perform coordinated movement to complete the lid opening and closing action; its characteristic is that the movement sequence of the two sets of cylinders mu...

Problems solved by technology

The first one, under the condition of sufficient height space, the oil cylinder performs single-axis reciprocating movement to complete the opening and closing action; this reciprocating mechanism is characterized by a large movement space and a single axial direction

The second type, under the condition of sufficient input and output units of the power source, can use double cylinders to carry out coordinated movement to complete the action of opening and closing the lid; its characteristic is that the movement sequence of the two sets of cylinders must be preset, and the coordinated movement must be accurate

The third is to use the turntable mechanism to complete the movement in different axial directions. Often the turntable mechanism controls the turntable to rotate in the specified direction through the ratchet to complete the opening and closing action. At the same time, it needs to limit its forward rotation and reverse rotation. Angle; its characteristic is that it cannot guarantee uniform motion. In the transmission process, once the transmission ratio changes, the rotation angle will be offset, and the phenomenon of dead point needs to be considered.

The characteristics of the above three situations determine that the operation difficulty and stability cannot support the normal operation of the heat preservation and pressure holding cabin in the environment of complex changes in deep sea pressure. Therefore, it is necessary to develop a new steering switch cover mechanism to overcome the current shortage of space. case, the difficulty of opening and closing the top cover
