Detailed Description

The following description is presented to disclose the utility model so as to enable any person skilled in the art to practice the utility model. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

The device suitable for mariculture of buried shellfish shown in fig. 1-2 comprises a culture unit, wherein the culture unit comprises a net cage 1 and a rope 3, a connecting branch rope 2 is fixedly connected to the outer surface of the net cage 1, one end of the connecting branch rope 2, which is far away from the net cage 1, is fixedly connected to the outer surface of the rope 3, and two ends of the rope 3 are respectively provided with a stable structure.

The number of the net cages 1 in each culture unit is not less than three, and the net cages 1 are arranged at equal intervals, so that the number of cultured shellfish is increased, and the culture quantity in a unit culture area is increased.

In the breeding process, the number of the breeding units is set to be not less than two and the breeding units are arranged in rows, the distance between the adjacent breeding units is kept at three meters, the specific number is set to be arranged according to the area of a breeding area, the influence between the adjacent breeding units can be reduced by keeping three meters, and the problem that the ropes are wound between the ropes 3 is solved.

The net cage 1 comprises at least two coaxially arranged annular frames 11, connecting rods 12 fixedly connected between the upper adjacent annular frame 11 and the lower adjacent annular frame 11 and on the inner sides of the annular frames 11, and net sleeves 13 sleeved on the outer surfaces of the connecting rods 12 and the annular frames 11, wherein the upper ends of the net sleeves 13 are provided with retractable ports, and the connecting rods 12 increase structural strength.

The retractable port comprises a rope opening 14 fixedly connected with the port at the upper end of the net sleeve 13, the rope opening 14 is in an annular tubular shape, two through holes are formed in the outer surface of the rope opening 14, the tightening rope 15 penetrates into the inner side of the rope opening 14 from one through hole and then penetrates out of the other through hole, the rope opening 14 can be manually squeezed and tightened, and the rope opening 14 can slide along the surface of the tightening rope 15 to be wrinkled together, so that the effects of quickly sealing and opening the net cage 1 are achieved. The two ends of the binding rope 15 are wound together and fixedly connected with the lower end of the connecting branch rope 2, so that the net cage 1 can be stably pulled when the connecting branch rope 2 is lifted up, and if the connecting branch rope 2 is directly connected to the surface of the net cage 1, the net cage 1 is easy to skew when being pulled, which brings inconvenience.

The interval between the two annular frames 11 at the top and the bottom is fifteen centimeters, so that the whole net cage 1 is suitable for the height of the shellfish culture requirement, the space is wasted due to overhigh height, and the shellfish living space is crowded due to overlow height.

The stable structure includes firm anchor 4, firm anchor 4 use common marine no pole anchor can, the surface of firm anchor 4 is close to upper end department and has seted up the round hole, and the one end of rope 3 is passed the round hole and is twined with firm anchor 4 and be connected.

When the device is used, the shellfish is placed in the net cage 1 and integrally sinks into the seabed, seabed sludge can enter the net cage 1 in the process of sinking into the seabed, the problem that the growth of the buried shellfish needs substrate is solved, the stabilizing anchors 4 at two ends are inserted into seabed soil, the stabilizing anchors 4 can be hooked into the soil when seawater flows to play a role in stabilizing the ropes 3, and in the later period, the ropes 3 are pulled to conform to the ropes 3 to find the connecting supporting ropes 2, so that the corresponding net cage 1 can be pulled up for adoption or collection, meanwhile, the net cage 1 also plays a role in protecting the shellfish, so that the shellfish is not attacked by enemy organisms, and the growth rate and the survival rate of the cultured shellfish are increased.
