Description

Technical Field

[0001] This utility model belongs to the field of marine ranching cage technology, specifically relating to a cage lowering device. Background Technology

[0002] Cage aquaculture utilizes netting assembled into cages of a specific shape, allowing water exchange between the inside and outside of the cage through the mesh, creating a living, dynamic environment suitable for fish. However, with the continuous development and increasing sophistication of cage aquaculture technology, traditional near-shallow sea cages are no longer sufficient to meet the growing demands of the industry.

[0003] When using a net cage, it needs to be lowered into the sea. Generally, a winch can be used to vertically lift and pull the net cage. The winch is equipped with a rope that can be connected to the net cage. However, if the rope is fixed to the net cage, it is often difficult to connect due to the size of the net cage, which affects the lowering operation. Utility Model Content

Depending on the size of the cage, it is convenient to connect the lifting and positioning rope to the cage, thereby improving the lowering operation effect.

[0005] This utility model provides the following technical solution: a cage lowering device, including a cage body, a winch body for driving the movement on the cage body, a lifting control rope on the winch body, a fastening cover fixedly connected to one end of the lifting control rope, a transverse groove on the cage body, a locking connection cover seat in the transverse groove, the top of the locking connection cover seat being open, the fastening cover being located at the top of the locking connection cover seat, two plug-in plates fixedly connected to the outside of the fastening cover, a fixing pin inserted into the plug-in plate, and one end of the fixing pin being inserted into the locking connection cover seat.

[0006] The top four corners of the snap-fit ​​cover are all fixedly connected with reinforcing ropes, one end of which is fixedly connected to the lifting control rope.

[0007] The locking connection cover is fastened to the body of the cage, and the open end of the locking connection cover is opposite to the top of the body of the cage.

[0008] The card slot connecting the cover has a plug groove in the middle of its side, and the plug plate is inserted into the plug groove.

[0009] The plug plate has an elastic connection groove, and the fixed pin is slidably connected in the elastic connection groove.

[0010] The elastic connecting groove is connected to an elastic element for limiting the position of the fixing pin, and the fixing pin is pulled outward to compress the elastic element.

[0011] The number of the four locking connection covers is four, and the four locking connection covers are respectively distributed at the four corners of the top of the cage body.

[0012] The beneficial effects of this utility model are:

[0013] A locking cover is fixedly connected to one end of the lifting control rope. The cage body has a transverse groove with a locking connection cover inside. The top of the locking connection cover is open. When the cage is lowered, the lifting control rope can be connected to it, so that the locking cover is fastened to the locking connection cover. The locking connection cover is located in the transverse groove and can be locked in the transverse groove by the action of the fixing pin, so that the locking connection cover and the locking cover form a closed loop. Depending on the size of the cage, it is convenient to connect the lifting control rope to the cage, improving the efficiency of the lowering operation.
