First support shaft is supported axis connection with first by clutch by third；
4th, liquid nitrogen is passed through toward the quick-frozen interior of Liquid Nitrogen Cooling Room, and aquatic products are freezed.
In four steps:
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 rotated around horizontal shaft；
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 horizontal shaft with certain speed；Placing net cylinder rotation
During turning, the aquatic products placed in net cylinder will constantly roll, to improve aquatic products freezing uniformity, improve aquatic products
The whole freezing efficiency and freezing quality of product.
The liquid nitrogen quickly cooling structure used on the ocean goer of our embodiment directly applies on hull, can utilize and swim in
The characteristic that hull on sea can shake places net cylinder rotation to drive, and then improves aquatic products and freeze uniformity.
On the other hand, the liquid nitrogen quickly cooling structure used on the ocean goer of our embodiment is not necessarily to additional power-equipment and energy
Electronic placement net cylinder rotation is carried out in source (such as motor and electric energy), can effectively reduce the consumption of the liquid nitrogen quickly cooling structure used on ocean goer
Can, in the case of this is inherently very limited for the boat-carrying energy for, be meaningful.
