Description

Technical Field

[0001] The utility model relates to the technical field of marine aquaculture, in particular to an aquaculture cage anchored in a floating posture. Background Art

[0002] In order to realize the functions of lifting and fishing, sinking and avoiding disasters more conveniently in large-scale aquaculture cages, cylindrical or spherical cages are used in the current public technology, and a float that can rotate along the circumference of the cage is used in combination. The float changes its relative position to make the cage rise or fall. The movement of the float in this type of cage is realized as follows: the float is connected to a "walking trolley" or "rotating arm", and the walking trolley or rotating arm walks around the circular track outside the cage, thereby driving the float to move. If the float is rigidly connected to the walking trolley or rotating arm, the float will rotate accordingly, and it will be impossible to obtain a deck surface that is always in a horizontal position. If the float is hinged to the walking trolley or rotating arm to release the rotation constraint, the float's posture is easily affected by waves, currents or eccentric loads on the deck surface, and a large rotation occurs, which is also not conducive to its activities and operations on the deck.

[0039] How it works

[0040] like Figure 5 , when the trolley or the rotating arm rotates at an angle α, driven by the follower gear, the gear plate and the floating body connected to it rotate in the opposite direction at an angle β. When the size parameters meet R1 / R2=R3 / R4, α=β, then the floating body's self-rotation angle can always offset the rotation angle of the trolley or the rotating arm, so that the floating body's posture remains unchanged and its upper deck is always in a horizontal position. Under the action of external waves, currents and eccentric loads, the force generated by the follower gear and the floating body's rotating shaft can form a couple to resist the torque generated by the external force, so that the floating body maintains a fixed posture.

[0041] The specific derivation process is as follows: When the size parameters satisfy R1 / R2=R3 / R4, it is assumed that the overall posture of the float remains unchanged (the float does not rotate). Specifically, the two walking components need to move symmetrically at the same time so that the two floats always remain in symmetrical positions on both sides of a certain vertical surface of the cage, so that when the float floats on the water surface, this vertical surface of the cage can always remain vertical without deflection.

[0042] Since the follower assembly is always in meshing state with the annular track 3 and the toothed disc 5, when the walking assembly rotates around the central axis of the cage by an angle α, the length of the arc swept by the meshing point on the annular track 3 is S1=α*R1, and accordingly, the rotation angle of the large gear on the follower assembly around its own rotation axis is θ=S1 / R3=α*R1 / R3. The large and small gears on the follower assembly are coaxially fixed, and the rotation angles of the two are the same, so the length of the arc swept by the meshing point on the small gear (that is, the meshing point on the toothed disc) is S2=θ*R4=α*R1*R4 / R3, and accordingly, it can be obtained that the angle β of the toothed disc 5 rotating around its own central axis is β=S2 / R2=α*R1*R4 / R3 / R2.

[0043] When R1*R4=R2*R3, β=α, that is, the rotation angle of the floating body and the rotation angle of the rotating arm are equal in magnitude and opposite in direction, and cancel each other out. When the cage as a whole does not rotate, the floating deck can always remain horizontal as shown in the figure.

[0044] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
