Across the sea due to hull floating, shaking can constantly be generated in wave effect pontoon；And it was shaken in hull
Cheng Zhong, clump weight can be swung back and forth around the first support shaft (around the first support shaft clockwise oscillation or counter-clockwise swing).
Since connecting bushing is rotatably arranged in the first support shaft by unilateral bearing, with unilateral bearing around the first support
Axis can be freely rotated clockwise, and for locking in the counterclockwise direction: in clump weight around the first support shaft up time
When needle is swung, the first support shaft does not rotate；When clump weight is around the first support shaft counter-clockwise swing, clump weight will pass through company
Extension bar, connecting bushing and unilateral bearing drive the first support shaft to rotate counterclockwise, and then pass through driving gear and driven gear band
Dynamic net cylinder of placing is around the second horizontal shaft rotation；
In addition, the outer diameter due to driving gear is much larger than the outer diameter of driven gear, in this way in clump weight around the first support shaft
During swinging back and forth, placement net cylinder will be driven constantly to rotate around the second horizontal shaft with certain speed；Placing net
In cylinder rotary course, the aquatic products placed in net cylinder will constantly roll, to improve aquatic products freezing uniformity, improve
The whole freezing efficiency and freezing quality of aquatic products.
The shrimps spiral overturning liquid nitrogen quickly cooling structure of our embodiment directly applies on hull, can utilize and swim in sea
The characteristic that hull on face can shake places net cylinder rotation to drive, and then improves aquatic products and freeze uniformity.
On the other hand, the shrimps spiral overturning liquid nitrogen quickly cooling structure of our embodiment is not necessarily to additional power-equipment and the energy
(such as motor and electric energy) carrys out electronic placement net cylinder rotation, can effectively reduce the energy consumption of shrimps spiral overturning liquid nitrogen quickly cooling structure,
It is meaningful in the case of this is inherently very limited for the boat-carrying energy.
In addition, in the 5th step, when one of spin refrigeration device freezes in liquid nitrogen frozen room, liquid nitrogen frozen
Another spin refrigeration device of outside can carry out the operation of second step, and aquatic products to be frozen are packed into and place net cylinder
It is interior, to improve whole refrigeration operation efficiency.
6th, after the completion of the aquatic products freezing on the spin refrigeration device in liquid nitrogen frozen room, liquid nitrogen frozen will be located at
Indoor spin refrigeration device is moved to the outside of Liquid Nitrogen Cooling Room；
Then, another spin refrigeration device is moved in liquid nitrogen frozen room by main guide rail, aquatic products is carried out cold
Freeze.
