Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically to a fish and shrimp co-culture isolation net. Background Technology

[0002] Fish and shrimp polyculture isolation net technology, as a modern ecological aquaculture model, enables fish and shrimp to be raised together in the same pond through physical separation, which can effectively utilize water space and promote ecological cycle.

[0003] Chinese patent CN205511627U discloses a fish and shrimp polyculture enclosure net, which includes several fixed posts and several net panels. The net panels and fixed posts form a closed structure. Each net panel has a sinking net bag at the bottom. The mesh diameter of the net panels is 3-4 cm. However, this device still has the following problems. 1. Different aquatic products require different rearing depths during cultivation, but the rearing depth of the enclosure is fixed, making it difficult to meet the rearing depth requirements of aquatic products such as fish, shrimp, and bullfrogs. 2. Different types of aquatic products or aquatic products at different stages need to be raised in isolation, but the enclosure net controls the breeding area in a relatively fixed manner, making it inflexible in use.

[0004] Based on this, this utility model designs a fish and shrimp co-culture isolation net to solve the above problems. Utility Model Content

The adjusting device 43 is installed on the isolation net 41 to adjust the position of the isolation net 41.

[0022] In this utility model, the rotating locking device 32 drives the transmission device 31, thereby driving the float 33 to move vertically, which can adjust the wading depth of the support frame 2. The isolation net 41 is adjusted in position within the support frame 2 by the adjustment device 43 and fixed in position by the fixing device 42, which can divide the internal area of ​​the support frame 2 to meet the aquaculture needs of different aquatic products.

[0023] In this embodiment, the transmission device 31 includes a first rotating shaft 311, pulleys 312, belt 313, and first connecting blocks 314. Two first connecting blocks 314 are fixedly installed at the upper and lower ends of the support frame 2. Two first rotating shafts 311 are arranged on the upper and lower sides of the outside of the support frame 2, and the two ends of the first rotating shafts 311 are rotatably connected to the two first connecting blocks 314 respectively. Two pulleys 312 are located at the two ends of the first rotating shafts 311 respectively, and the two pulleys 312 are fixedly connected to the two ends of the first rotating shafts 311 respectively.

The end of the first bolt 321 passes through the first threaded hole 322 and abuts against the outer wall of the first rotating shaft 311 on the upper side.

[0025] In this utility model, the end of the first bolt 321 is unscrewed, and the handle 323 is rotated to drive the first rotating shaft 311 to rotate, thereby driving the upper pulley 312 to rotate, causing the belt 313 connected to the upper pulley 312 to rotate. At this time, the float 33 installed on the belt 313 also moves up and down with the belt 313. When a suitable wading depth is reached, the first bolt 321 is screwed in to fix the first rotating shaft 311, which can realize adjustment and fixation for different water depth requirements.

[0026] In this embodiment, the fixing device 42 includes a second connecting block 421, a second bolt 422, and a second rotating shaft 423. One end of the second connecting block 421 is fixedly installed inside the upper and lower ends of the support frame 2.

The hooks 432 are fixedly connected to the connecting plate 431 and can be hooked to the fixing rod 433.

[0028] In this utility model, the end of the second bolt 422 is loosened, allowing the second rotating shaft 423 to rotate, pulling out the outer end of the isolation net 41. The outer end of the isolation net 41 is fixed by the engagement between the hook 432 on the connecting plate 431 and the fixing rod 433. The isolation net 41 is extended and retracted by the second rotating shaft 423. After the area is divided by the isolation net 41, the second bolt 422 is screwed in to lock the second rotating shaft 423, thereby fixing the length of the isolation net 41. This allows the area within the support frame 2 to be arbitrarily divided to meet different requirements.
