Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of cockle farming equipment, and particularly relates to a cockle shallow sea farming device. Background Technology
[0002] The blood clam (Ceratophyllum demersum) is a mollusc belonging to the family Ceratophyllum in the order Ceratophyllum. It is also known as the hairy clam, large hairy clam, red clam, and blood clam. Its shell is large, obliquely oval or triangular-fan-shaped, and extremely inflated, with the two shells being roughly equal in size. It can be cultured in net cages in shallow seas.
[0003] Placing the cages at the bottom of the water increases their resistance to wind and waves, while raising them makes it easier to capture the cockles inside. However, the operation of removing or adding slings to control the raising and lowering of the cages is quite troublesome, which makes the raising and lowering of conventional cockle farming cages rather complicated.
[0004] Therefore, we propose a shallow-sea aquaculture facility for clams to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to solve the problem of the cumbersome operation of conventional cockle farming cages, and to propose a cockle shallow sea farming device.
[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0007] A shallow-sea aquaculture device for cockles includes a net bag with pull ropes evenly fixed to its lower part. A restraining frame is fixedly connected to the upper end of the pull ropes. An annular airbag is fitted over the restraining frame, and an inflation tube is fixedly connected to the annular airbag. An air nozzle is fixedly connected to the upper end of the inflation tube. After the device is placed in seawater, the air nozzle is opened, allowing high-pressure gas inside the annular airbag to escape through the inflation tube and air nozzle, reducing the buoyancy of the annular airbag until the device sinks. Then, air is injected into the inflation tube through the air nozzle, causing the gas to expand the annular airbag outwards, increasing its buoyancy until the device floats upwards, facilitating control of the device's buoyancy.
[0008] Preferably, a buoyancy ring is fixedly connected to the upper part of the inflation tube. The buoyancy ring lifts the upper end of the inflation tube, allowing the inflation tube to act on the air nozzle, keeping the air nozzle on the water surface, making it convenient for the user to operate the air nozzle on the water.
[0009] Preferably, a float is fixedly connected to the upper end of the net. The float increases buoyancy to the upper part of the net, facilitating the downward shift of the net's center of gravity in the water.
[0010] Preferably, a weight is fixedly connected to the lower end of the net. This weight increases the gravity at the bottom of the net, facilitating a further downward shift of the net's center of gravity in the water.
[0011] Preferably, the net includes a first elastic ring, an elastic post, a second elastic ring, and a retaining net. The elastic post is evenly and fixedly connected between the first and second elastic rings, and the retaining net is fixedly connected between the first elastic ring, the elastic post, and the second elastic ring. The first elastic ring, the elastic post, and the second elastic ring expand the retaining net, which then keeps the clams inside, facilitating their enclosure.
[0012] Preferably, the restraint frame includes an L-shaped rod, a first fixing ring, and a second fixing ring. The L-shaped rod is evenly and fixedly connected to the outside of the first and second fixing rings. The first and second fixing rings stabilize the position of the L-shaped rod, and the L-shaped rod restrains the annular airbag. The upward buoyancy of the annular airbag acts on the L-shaped rod, which in turn acts on the pull rope, causing the pull rope to act upward on the net, facilitating the upward pulling of the annular airbag through the restraint frame and the pull rope.
[0013] Preferably, the annular airbag includes an annular body and a connecting seat, with the lower end of the connecting seat fixedly connected to the annular body. After gas is injected into the inflation tube through the air nozzle, the gas is then injected into the connecting seat through the inflation tube, and the gas is introduced into the annular body through the connecting seat, increasing the volume of the annular body. Opening the air nozzle allows the gas inside the annular body to be discharged outward, reducing the gas volume in the annular body, thus facilitating changes in the volume of the annular airbag through gas flow.
[0014] In summary, the technical effects and advantages of this utility model are as follows:
[0015] 1. After placing the device in seawater, open the air nozzle to allow the high-pressure gas inside the annular airbag to be discharged outward through the inflation tube and air nozzle, reducing the buoyancy of the annular airbag until the device sinks; then inject air into the inflation tube through the air nozzle to expand the annular airbag outward, increasing the buoyancy of the annular airbag until the device floats upward, making it easier to control the device's floating and sinking.
[0016] 2. Use the buoyancy ring to float the upper end of the air tube, so that the air tube acts on the air nozzle, keeping the air nozzle on the water surface, making it convenient for the user to operate the air nozzle on the water surface.
[0017] 3. Use the first elastic ring, elastic column and second elastic ring to open the barrier net, and use the barrier net to keep the cockles inside, making it convenient to raise cockles.
[0018] 4. The first and second fixing rings stabilize the position of the L-shaped rod, and the L-shaped rod restrains the annular airbag, so that the upward buoyancy of the annular airbag acts on the L-shaped rod, which in turn acts on the pull rope, causing the pull rope to act upward on the net, making it convenient for the annular airbag to be pulled up by the restraint frame and the pull rope.
[0019] 5. After injecting gas into the inflation tube through the air nozzle, inject the gas into the connector through the inflation tube, and then introduce the gas into the annular bladder through the connector to increase the volume of the annular bladder; open the air nozzle to allow the gas in the annular bladder to be discharged outward, reducing the gas volume in the annular bladder and making it easier to change the volume of the annular bladder by gas.

[0030] Reference Figure 1 and 2 The net 2 includes a first elastic ring 21, an elastic column 22, a second elastic ring 23, and a retaining net 24. A float 7 is fixedly connected to the upper end of the first elastic ring 21, a weight 6 is fixedly connected to the lower end of the second elastic ring 23, and the lower end of the pull rope 5 is fixedly connected to the elastic column 22 and the second elastic ring 23. The elastic columns 22 are evenly fixedly connected between the first elastic ring 21 and the second elastic ring 23. The retaining net 24 is fixedly connected between the first elastic ring 21, the elastic column 22, and the second elastic ring 23. The first elastic ring 21, the elastic column 22, and the second elastic ring 23 are used to open the retaining net 24, thus trapping the clams inside.
[0031] Reference Figure 1 , 3 The restraint frame 3 includes an L-shaped rod 31, a first fixing ring 32, and a second fixing ring 33. The upper end of the pull rope 5 is fixedly connected to the lower end of the L-shaped rod 31. The L-shaped rod 31 is evenly fixed to the outside of the first fixing ring 32 and the second fixing ring 33. The first fixing ring 32 and the second fixing ring 33 stabilize the position of the L-shaped rod 31. The L-shaped rod 31 restrains the annular airbag 4, so that the upward buoyancy of the annular airbag 4 acts on the L-shaped rod 31, and through the L-shaped rod 31, it acts on the pull rope 5, so that the pull rope 5 acts upward on the net bag 2.
[0032] Reference Figure 1 , 3 The annular airbag 4 includes an annular body 41 and a connecting seat 42. The annular body 41 is fitted onto the lower part of the L-shaped rod 31. The lower end of the inflation tube 1 is fixedly connected to the inside of the connecting seat 42, and the lower end of the connecting seat 42 is fixedly connected to the annular body 41. After gas is injected into the inflation tube 1 through the air nozzle 9, gas is injected into the connecting seat 42 through the inflation tube 1, and then the gas is introduced into the annular body 41 through the connecting seat 42, increasing the volume of the annular body 41. Opening the air nozzle 9 allows the gas inside the annular body 41 to be discharged outward, reducing the gas volume in the annular body 41.
[0033] Working principle: After the device is placed in seawater, the air nozzle 9 is opened to allow the high-pressure gas inside the annular airbag 4 to be discharged outward through the inflation tube 1 and the air nozzle 9, reducing the buoyancy of the annular airbag 4 until the device sinks; then air is injected into the inflation tube 1 through the air nozzle 9, causing the gas to expand the annular airbag 4 outward, increasing the buoyancy of the annular airbag 4 until the device floats upward, making it easier to control the floating and sinking of the device.
