  The above-mentioned distress signal transmitter can not be mounted with a large weight to be mounted on a drone. It is necessary to go underwater and search. Searching for a drone with a search underwater vehicle system is expensive.

  When a drone falls into water such as a river, a pond or the sea, if it falls above the water surface, there is no way but to dive into the submerged drone and rescue it.

  As with the drone, if the fishing gear is dropped into the water, the fishing gear will be rescued in the same manner as described above.

  There is a limit to the rescue of the submerged drone and fishing gear mentioned above, and it is abandoned to rescue, and the drone and fishing gear are dumped in the water as waste. In the rescue of drone and fishing gear, there is also concern about the danger related to human life.

  The present invention has been made in view of the above circumstances, and it is an object of the present invention to safely rescue a drone or fishing tackle from the water even if it does not dive into the submerged drone or fishing tackle.

  Further, in order to achieve the above object according to the present invention, according to the first problem solving means, a bobbin wound with a line fixed with a water-soluble adhesive and a bobbin are accommodated, and a float case line discharge hole is formed.

  A bobbin 1 (a cylindrical tool for winding a yarn and having a cylindrical or cylindrical shape with circular plates attached at both ends) is wound with a bobbin 1 wound with a line 4 fixed with a water-soluble adhesive that is soluble in water. A search float for storing in the float case 2 whose density is smaller than water and connecting the line 4 wound around the bobbin 1 to the line 4 and the drone (object to be searched) through the float case line discharge hole 5 The fixing bracket 3 is connected, and the air release hole 6 at the time of submersion is provided.

  The search float fixing bracket 3 and the drone are firmly connected by using a binding band or the like. At all times (when not submerged), the line 4 of the bobbin 1 is restrained by the water-soluble adhesive, so the drone is not released from the discharge hole 5 and the search float is attached It is used as it is.

  If the drone falls and sinks on the water, the drone and the search float reach the bottom of the water because the search float fixing bracket 3 and the drone are connected. While the air is discharged from the float case line discharge hole 5 and the air discharge hole 6 of the search float, water flows into the inside of the float case 2. The water-soluble adhesive of the bobbin 1 wound with the water-soluble adhesive-restrained line 4 reacts with water, and the water-soluble adhesive dissolves to release the bobbin 4 of the line 4. As a result of the buoyancy, the search float starts to float toward the water surface, and the released line 4 sequentially discharges the line 4 from the float case line discharge hole 5. The float case 2 rises in the water while discharging the line 4 and reaches the water surface. You can rescue the drone by pulling up the line 4 connected to the float case 2 floating on the water surface.

  Next, a first embodiment of the invention will be described with reference to FIGS.

  FIG. 4 is a view showing the drone according to the present invention mounted on the drone leg 12 of the drone main body 17. The search float fixing bracket 3 of the search float 14 is fixed to the drone leg 12 with a fixing band 13. At all times (when not submerged), the line 4 of the bobbin 1 is restrained by the water-soluble adhesive, so the drone is not released from the discharge hole 5 and the search float is attached It is used as it is.

  FIG. 5 is a view showing a state where the drone falls into the water. The drone body 17 falls on the water, and the drone body 17 and the search float 14 reach the water bottom 16. In this figure, with the drone body falling on water and submerged from the water surface 15 to the water bottom 16, the search float 14 turns to the direction of the water surface 15 by buoyancy, and the float case line discharge hole 5 of the search float and the air discharge hole The water flows into the float case 2 while releasing the air from 6. The water-soluble adhesive of the bobbin 1 wound with the water-soluble adhesive-restrained line 4 reacts with water, and the water-soluble adhesive dissolves to release the bobbin 4 of the line 4. The search float 14 starts floating toward the water surface 15 by buoyancy.

  FIG. 6 is a diagram in which the search float is discharged to the water surface, and with the search float 14 floating on the water surface 15 by buoyancy, if the line 4 connected to the float case 2 floating on the water surface is pulled up, You can rescue

  Even if the drone is submerged in the water, the search float can safely rescue the drone without diving in the water if it can find the search float floating on the water surface.

  Next, a second embodiment of the invention will be described with reference to FIGS.

  FIG. 7 is a plan view of a search float showing a second embodiment of the present invention, FIG. 8 is a sectional view taken along the line AA of the search float, and FIG. 9 is a sectional view taken along the line BB of the search float.

At all times (when not submerged), the line 4 of the bobbin 1 is restrained by the water-soluble adhesive, so that the drone will not be released from the release hole 5, and the drone will be released from the float case 2 and The float 7 is used while being connected.

When the drone is submerged, the drone and the search float reach the bottom of the water because the float case 2 is fixed to the drone. While the air is discharged from the release float fixing hole 8 of the search float, the float case line discharge hole 5 and the air discharge hole 6, water flows into the inside of the float case 2. The water-soluble adhesive of the bobbin 1 wound with the water-soluble adhesive-restrained line 4 reacts with water, and the water-soluble adhesive dissolves to release the bobbin 4 of the line 4.
The water-soluble adhesive fixing the release float and the float case also melts, and the release float and the float case separate. The release float 7 starts to float to the water surface by buoyancy, and the released lines 4 sequentially release the line 4 from the line discharge holes 5. While releasing the line 4 from the float case 2, the release float 7 ascends the water and reaches the water surface. The drone can be rescued by raising the line 4 connected to the discharge float 7 floating on the water surface.
