When aquatic products are cultivated, the oyster seedling string is tied to the plurality of raft pipes.

Since the oyster seedlings on the oyster seedling string will gradually increase in weight as they grow, the raft body will gradually sink as the weight of the oyster seedlings increases during the growth of the oyster seedlings, so that the oyster seedlings located at the lowest end of the oyster seedling strings will gradually sink. Close to the bottom of the culture pond, or even sink into the bottom of the culture pond, causing the growth of oyster seedlings to be affected. Therefore, in order to keep the oyster seedlings at the bottom of the raft at the optimal growth water level, operators will Heavy objects or floating objects are tied to the body to adjust the draft of the raft. However, it is inconvenient to operate by tying heavy objects or floating objects, and it is impossible to accurately adjust the draft of the raft. Water level.

As shown in Figure 6, the raft 60 is mainly applied to a raft (not shown). When the raft is placed in a pool, the plurality of covers 30 of the raft buoyancy adjusting device are Keep the through hole 11 and the extension channel 21 closed, wherein the operator can tie the oyster seedlings to the raft tube 60 of the raft body.

As shown in Figure 6, taking the second preferred embodiment of the creative raft tube buoyancy adjusting device as an example, when the oyster seedlings were first cultivated, since the oyster seedlings had not yet grown, the draft of the raft body was low, so The operator must inject water into the inner space 61 of the raft tube 60, thereby reducing the buoyancy of the raft tube 60 and increasing the draft of the raft body. As shown in Figures 6 and 7, when the operator is performing During the water injection operation of the raft pipe 60, the operator can first remove the plurality of covers 30, pull the sleeve 40 connected to the through hole 11 to the water surface, and at the same time extend the sleeve 40 connected to the extension pipe 20 into the water , The through hole 11 is used as a venting end, and the extension tube 20 is used as a water venting end.

Then, the operator can use the following methods to make water flow into the raft pipe 60: 1. As shown in Figure 7, the operator can connect the ventilation end to an external air extraction device, so that the air extraction device draws the air inside the raft 60 from the ventilation end. At this time, the A vacuum suction force is generated at the water-passing end, so that the water is sucked into the extension channel 21 and into the raft pipe 60. Finally, the operator can seal the through hole 11 and all the through holes 11 and all the holes with the multiple covers 30 The extension pipe 20 can complete the water injection operation. 2. As shown in Figure 8, the operator can connect the water-passing end to an external water pumping device 70 so that the water pumping device 70 can input water from the extension channel 21 to the internal space 61 of the raft pipe 60 At this time, the air in the internal space 61 of the raft tube 60 will be output from the venting end, and finally, the operator can seal the through hole 11 and the extension tube 20 with the plurality of covers 30 respectively, namely Can complete water injection operations.

As shown in Figure 9, when the oyster seedlings grow, the draft of the raft tube 60 will rise due to the weight of the oyster seedlings after they grow, so the operator must draw water from the inner space 61 of the raft tube 60. In this way, the buoyancy of the raft pipe 60 is increased, and the draft water level of the raft body is reduced. When the operator is pumping the raft pipe 60, the operator can first remove the plurality of covers 30 and connect the through holes The sleeve 40 of 11 and the sleeve 40 connected to the extension pipe 20 are both pulled to the water surface. At this time, the through hole 11 is the vent end, and the extension pipe 20 is the water passage end.

Wherein, when the operator is performing pumping operations, the operator can pump water from the water passage end. At this time, air will enter the internal space 61 of the raft tube 60 from the ventilating end. After the water inside the raft pipe 60 is pumped out and the raft pipe 60 is at a predetermined draft water level, the operator can seal the through hole 11 and the extension pipe 20 with the plurality of covers 30 to complete the water injection operation.

Furthermore, the operator can adjust the buoyancy of the raft tube 60 by water injection or pumping. When the walrus is not good, the operator can fill the inner space 61 of the raft tube 60 with water, reducing the raft tube 60 60 buoyancy, so that the raft body sinks to the seabed as a whole to avoid wind and waves and avoid damage to the raft body. In addition, the operator can pass through the casing 40 or take over externally In this way, the raft pipe 60 is directly injected or pumped on the sea surface, so the operator does not need to dive to the seabed for operation, which can greatly improve the safety of the operation.

In addition, as shown in Figures 10 and 11, since the extension tube 20 extends axially toward the inner space 61 of the raft tube 60, when the raft tube 60 is inclined, the operator can follow Regarding the floating condition of the raft tube 60, the through hole 11 or the extension tube 20 located above the water level in the internal space 61 of the raft tube 60 is set as the venting end and will be located in the internal space 61 of the raft tube 60 The extension pipe 20 or the through hole 11 below the water surface is set as the water-passing end. The following respectively describes the pumping or water injection operation in two different inclined forms.

As shown in FIG. 10, when the end cap 10 is higher than the raft tube 60, the through hole 11 will be located above the water surface inside the raft tube 60, and the extension tube 20 will extend into the raft tube 60. Below the water surface inside the pipe 60, at this time, the operator can set the through hole 11 as the vent end, and set the extension pipe 20 as the water end, and pull the sleeve 40 connected to the through hole 11 out of the water surface , Then, the operator can pump or fill the water through the end.

As shown in Figure 11, when the end cap 10 is lower than the raft tube 60, the through hole 11 will be located below the water surface inside the raft tube 60, and the extension tube 20 will extend out of the raft tube 60. The water surface inside the pipe 60. At this time, the operator can set the extension pipe 20 as the vent end and the through hole 11 as the water passage end, and pull the sleeve 40 connected to the extension pipe 20 out of the water surface, Then, the operator can pump or fill the water through the end.

In summary, this creative raft tube buoyancy adjusting device can use the through hole 11 or the extension tube 20 as the water passage end and the ventilation end, respectively, and because the extension tube 20 is directed toward the inner space 61 of the raft tube 60 Axial extension, the difference in the distance between the port of the extension tube 20 and the through hole 11 can prevent the distance between the water end and the vent end from being too close during the pumping process to affect each other, so when pumping or During the water injection operation, water and air can be separated into and out, which can effectively improve the efficiency of water pumping or water injection. In addition, when the walrus is not good, the operator can fill the internal space 61 of the raft pipe 60 with water to make the raft The whole body sinks to the seabed, thereby avoiding wind and waves to avoid damage to the raft body by wind waves.
