Specifically, the power generation structure includes a ring plate 8, a generator 9, and a transmission structure.

The annular plate 8 is fixedly arranged on the side wall of the floating block 1 through a connecting plate 81, and the rotating surfaces of the annular plate 8 and the rotating rod 71 are parallel.

The generator 9 is fixedly arranged on the rotating rod 71, a gear 91 is fixedly arranged on an input shaft of the generator 9, a storage battery 12 is arranged on the floating block 1, and the generator 9 is electrically connected with the storage battery 12 through a rectifier.

The structure is provided on the annular plate 8, and the transmission structure can drive the gear 91 to rotate by using the rotation of the rotating rod 71.

Float bowl 7 fluctuates, makes dwang 71 rotate from top to bottom around two articulated shafts 72, and the gear 91 of generator 9 follows the luffing motion on dwang 71 drives gear 91 through transmission structure and rotates, makes generator 9 generate electricity, easy operation.

Specifically, the transmission structure includes an annular aperture 82 and an arcuate rack 83.

The annular hole 82 is formed in the annular plate 8, and the width of the annular hole 82 is larger than the diameter of the gear 91.

The arc-shaped rack 83 is fixedly arranged on one side wall of the annular hole 82 along the arc length direction, and the gear 91 is positioned in the annular hole 82 and is meshed and connected with the arc-shaped rack 83.

When the buoy 7 drives the rotating rod 71 to rotate up and down around the second hinge shaft 72, the gear 91 on the generator 9 moves along the annular hole 82, and the arc-shaped rack 83 drives the gear 91 to rotate, so that the generator 9 generates electricity, and the structure is simple.

The use method of the freshwater mussel culture device comprises the following steps:

s1, opening the limit structure, rotating the support rod 2 upwards, breeding each freshwater mussel in each breeding cage independently, connecting the breeding cages together in a detachable manner from top to bottom through a plurality of first chains 3, and connecting the weight 6 to the lowest breeding cage through a third chain 33;

s2, connecting the uppermost cultivation cage to the support rod 2 through the second chain 32, then rotating the support rod 2 downwards, and limiting the support rod 2 in the gap groove 211 of the supporting block 21 through the limiting structure;

s3, repeating the operations, putting a plurality of cultivation cage components into the corresponding through holes 11, opening the limiting structure after the cultivation is mature, upwards rotating the supporting rod 2, pulling the cultivation cage components out of the water surface, and taking out the mussels in each cultivation cage.

Each freshwater mussel seedling is independently placed in a culture cage for culture, so that the freshwater mussels are prevented from competing for nutrients, the freshwater mussels grow rapidly, and due to the fact that each culture cage is detachably connected, a plurality of culture cages can be connected in series according to culture needs and are respectively placed in different through holes 11, and the yield of the freshwater mussels is improved; in addition, the whole string of the cultivation cages can be pulled out of the water surface, so that the cultivation personnel can observe and catch conveniently, and the time and the labor are saved.
