Description

technical field

[0001] The invention belongs to the technical field of tidal current energy generation, and relates to a crab cage with an improved structure. Background technique

[0002] The crab cage is used as a tool for catching crabs. Its main body is a frame net cage structure, and holes are provided on the net to induce crabs to enter the cage body.

[0003] At present, the commonly used crab cages include fixed crab cages and telescopic crab cages. The size of the fixed crab cages is fixed, and the number of crabs caught is limited, while the telescopic crab cages are easily affected by waves, which will change the size of the crab cages and affect the crabs. into the cage.

[0004] In addition, several crab inlet holes are arranged around the crab cage. The crab inlet holes of existing crab cages are either too large or too small. When the crab inlet holes are large, the crabs in the crab cage can easily escape from the crab cage with the waves. , when the crab i...

Embodiment Construction

[0056] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0057] Such as Figures 1 to 6 As shown, a crab cage with an improved structure includes a connecting pipe 3, a first ring 1, a second ring 2, a first crab feeding mechanism, a second crab feeding mechanism, an adjustment mechanism and a telescopic mechanism.

[0058] The connecting pipe 3 is arranged horizontally.

[0059] The first ring 1 is coaxially arranged on the left end of the connecting pipe 3, and the first net cylinder 11 is connected between the first circular ring 1 and the left end of the connecting pipe 3, and the inner sidewall of the first net cylinder 11 A first helical spring 12 is provided on it, one end of the first helical spring 12 is fixedly connected to the first ring 1 , and the other end is fixedly co...
