Description

  The present invention relates to a buoyancy device, and more particularly, to a buoyancy device that can float a fish cage for fish farming, a box net of a stationary net, etc. near the water surface and can be used conveniently.

  In the fish farming industry, floating sinks and stationary nets are used, where box nets and floating floats are attached to a rectangular frame made of iron pipes in areas where the sea is rough.

  For example, Patent Document 1 discloses a floating float used for such a floating sink and a stationary net.

  FIG. 1 is a cross-sectional view of a floating float described in Patent Document 1. As shown in FIG. 1, the hollow body 11 of the float / float float has an air inlet 12 and an exhaust port 13 at the upper end exposed on the water surface, and has a water inlet / outlet port 14 at the lower end below the water surface, The water inlet / outlet port 14 is usually sealed by a sealing lid 15.

  When concealing such ups and downs float under the surface of the water, for example, to avoid rough seas, it is necessary for the diver to dive and remove the sealing lid 15 so that the seawater gradually enters the hollow body 11. Diving work in rough weather is dangerous.

  In order to avoid such a diving operation, a floating float 16 shown in FIG. 2 has been proposed. In the float and sink float 16 shown in FIG. 2, a water inlet / outlet pipe 17 that is curved so as to open toward the water surface in order to inject water into a portion exposed on the normal water surface of the side surface is disposed. ing. When concealing the float / float float 16 below the water surface, for example, an operation of standing at the upper end of the float / float float 16 is performed so that a person pushes the opening of the water inlet / outlet pipe 17 below the water surface to enter water. The work of standing or jumping between the floating floats 16 also involves the risk of falling water.

An injection pump 261 and a nozzle 262 projecting upward from the air injection pump 261 are provided.

  Next, the detailed configuration of the sealing means 24 will be described in detail with reference to FIGS. 3 and 4.

  First, as shown in the drawing, corresponding to the sealing means 24, the water surface lower portion 21 is a tubular first extending from the periphery of the bottom plate 212 of the water entrance / exit 211 to the inside of the hollow housing 2 (that is, the upper side of the bottom plate 212). The first guide cylinder 213 is formed with an annular diameter-reducing flange 214 that protrudes from the inner peripheral surface of the cylinder toward the water inlet / outlet 211 side of the first guide cylinder 213. On the upper surface of the diameter flange 214, that is, on the diameter-reduced flange 214, when the sealing means 24 moves to the sealing position toward the hollow housing 2 side, an annular contact that can come into contact with the sealing block 241 of the sealing means 24 is provided. A watertight ring 216 (second watertight ring) is fitted into the contact surface 215.

  Further, when the sealing projection 24 moves to the sealing position, that is, when the sealing means 24 moves to the sealing position, a watertight ring 243 (first Of watertight ring).

  With this configuration, when the sealing means 24 moves to the sealing position and the sealing projection 242 is inserted into the ring of the reduced diameter flange 214, the annular contact that faces the sealing block 241 at the reduced diameter flange 214 is achieved. The gap between the surface 215 and the sealing block 241 is watertightly closed by the watertight ring 216, and between the sealing projection 242 inserted into the ring of the reduced diameter flange 214 and the inner peripheral surface of the reduced diameter flange 214. The watertight ring 243 also seals the gap in the watertight ring 243. Therefore, when the sealing means 24 operates downward along the extending direction of the first guide tube 213 and moves to the sealing position as shown in FIG. It is possible to seal the doorway 211 in a watertight manner.

  Further, when the sealing unit 24 is operated upward along the extending direction of the first guide cylinder 213 from the sealing position, the sealing block 241 and the sealing protrusion 242 are separated from the reduced diameter flange 214, so that the water inlet / outlet 211 Is opened, and seawater and the like can enter the fluid storage space 23 via the water entrance / exit 211.

  Next, the detailed configuration of the control means 25 for controlling the sealing means 24 will be described in detail with reference to FIGS.

  As shown in the figure, the upper surface 22 of the water surface corresponding to the control means 25 has an operation hole 223 opened in the top plate 222 of the hollow housing 2 toward the water entrance / exit 221, and the top plate of the operation hole 223. 222 is further provided with a second guide cylinder 224 extending from the peripheral edge to the inner side of the hollow housing 2, that is, the side where the water inlet / outlet port 221 and the sealing block 241 are disposed, on the inner cylinder surface of the second guide cylinder 224. An internal thread is formed.

  One end of the control means 25 is attached to the upper end of the sealing block 241 of the sealing means 24 as an attachment end 252, and the other end is inserted as an operation end 253 through the second guide tube 224 and the operation hole 223.

Incidentally, in this embodiment, the operation end 253 has a hexagonal cross section, and when the operation end 253 is rotated by a hexagonal screwdriver of a corresponding size, the female screw of the second guide cylinder 224 and the male screw 255 of the control rod 251 are used. However, the present invention is not limited to this, and the vertical movement of the control rod 251 is controlled by the operation of the operation end 253 of the control rod 251. Any configuration that can be applied to the present invention.

  Further, the restriction block 254 moves the movable range of the control rod 251 by a distance so that the sealing block 24 of the sealing device 24 does not come off the first guide cylinder 213 by the operation of the control device 25, that is, the vertical movement of the control rod 251. Even if the control rod 251 moves upward and reaches the limit position where the limit block 254 contacts the lower end of the second guide cylinder 224 as shown in FIG. Although the stop block 24 is installed so as to remain in the cylinder of the first guide cylinder 213, the present invention is not limited to this, and the sealing block 24 operates the control means 25, that is, the upper and lower sides of the control rod 251. Any configuration that does not disengage from the first guide cylinder 213 by movement can be applied to the present invention. For example, a configuration in which the first guide cylinder 213 is extended upward or the second guide cylinder 224 is extended downward is also conceivable.

As shown in the figure, the hollow housing 2 is formed in a hollow annular frame, and the aquaculture box net 4 is fixed to the hollow housing 2 via a fixed arm 3.

  With this configuration, when the weather or the sea is rough and it is necessary to retract the aquaculture box net 4 below the surface of the water, the operation of the control rod 251 standing on the hollow housing 2 and exposed above the top plate 22 is performed. If the end 253 is turned, the control rod 251 and the sealing means 24 are pulled up to open the water entrance / exit 211 and allow seawater or the like to enter the fluid storage space 23.

  When it is desired to float the aquaculture box net 4 on the surface of the water, the air injection pump 261 attached to the air inlet / outlet 221 is first activated and an air introduction pipe (not shown) attached to the nozzle 262 is installed. Air is injected into the fluid storage space 23, and the seawater or the like entering the fluid storage space 23 is discharged through the water inlet / outlet 211, and then the control rod 251 exposed above the top plate 22. The water inlet / outlet port 211 can be sealed by turning the operation end 253 to push the sealing means 24 down to the sealing position.

  Therefore, if the buoyancy device of the present invention is introduced, the operation of jumping between dives and floats is not necessary, and the operator can be safe.

  With the above configuration, the buoyancy device of the present invention can open and close the water inlet / outlet by controlling the reciprocating operation of the sealing means by the operation above the upper surface of the water surface, so there is no risk of diving or falling water. Since a buoyancy device capable of safely performing an injection operation for allowing water to enter the hollow housing can be provided, the present invention can be applied particularly to floating and sinking ginger and stationary nets that are widely used in the fish farming industry.
