Description

[Detailed explanation of the idea] The invention of this application relates to a water rescue device.

In the past, various methods of rescuing victims of water disasters have been considered, but in order to give buoys, rubber boats, or cages to the victims of water disasters using a helicopter, the first method was to hang these life-saving devices from the helicopter. Victims use their own knives to grab lifesaving equipment and then use it.
These rescue tools had the disadvantage that they were not practical unless they were in a condition where they could be used.

As a result, it is almost impossible to rescue victims who cannot move with their own blades, and even if auxiliary rescuers jump from a helicopter to the water surface, it is extremely difficult to load victims into cages, etc. Instead of rescuing the victims, there was even a risk that the auxiliary rescue workers would be in double trouble.

In addition, a life-saving network has been developed in which a helicopter is used to lower a mesh to rescue injured or unconscious people on or in the water (see Japanese Patent Publication No. 47-20705). In order to create a structure suitable for raising and lowering the net, a lift cable is placed above the net, an anchor is attached to the bottom of the net via a string, and a floating member is placed in the middle of the net. However, this life-saving net has the disadvantage that even when used in bad weather, where water accidents are relatively likely to occur, it is extremely difficult to get the body of the victim who is moving from place to place due to rough seas into the net. there were.

Therefore, the inventor of this application wondered if it would be possible to quickly and reliably scoop up and rescue victims even in rough weather by creating a structure that makes it easier to drag the net horizontally. I worked on it.

Therefore, the invention of this application is to solve the above problems,
The object of this invention is to provide a water rescue device that can directly scoop up and rescue disaster victims using a net.

Next, a specific configuration for achieving the above object will be explained with reference to the drawings. A net-like body 2 having a peripheral edge 1 having a nearly triangular planar shape is provided, and a floating body 3 is provided at the rear peripheral edge of the net-like body 2.
are attached horizontally and laterally, and the peripheral edge 1 of the net-like body 2 is
A traction net 10 is attached to the traction net 10 , anchors 4 are attached to appropriate positions on the traction net 10 , and the tips of the portions of the traction net 10 located on both side peripheral edges of the net 2 are attached to the front of the net 2 . The traction nets 10 are extended further forward from the section so that the traction nets 10 become substantially integrated at appropriate positions, and the integrated traction nets 10 are inserted into the penetrating portion of the annular weight 12. This is a water rescue device in which the front part of the net-like body 2 is lowered into the water by the annular weight 12 during insertion and use, so that the central part of the net-like body 2 is formed into a deep bag-like shape.

In addition, among the constituent elements of this invention, the specific structure other than the gist of this invention will be explained with reference to the drawings, especially FIG. Attach a sea anchor 4 or a weight 5 such as a chain,
An air injection lower for injecting air into the floating body 3 using a cylinder 6 or the like, a seawater battery 8 for operating to open the cylinder upon landing on water, and an air venting device 9 for removing air from the floating body 3 after rescue. , and the peripheral edge 1 of the net-like body 2
A towing net 10 is attached to the towing net 10, a weight 11 is attached to an appropriate position on the net-like body 2, and an annular weight 12 having a weight and pulling effect is attached to the towing net 10, and an exhaust port 17 of the floating body.
This is a water rescue device equipped with a

Furthermore, as shown in FIG. 2, the floating body 1 has a substantially triangular shape.
3, a floating body 14 having a substantially elliptical shape as shown in FIG. 3, or a floating body 15 having a substantially polygonal shape as shown in FIG. Even if a disaster victim falls from the net-like body over the floating body 3 attached horizontally and laterally, he or she can be caught in the net behind it.

Furthermore, the floating body can be made into an arc-shaped body 16, which reduces the risk of disaster victims being evacuated from side to side.

Next, to explain the effects resulting from the above configuration, during water rescue operations in rough weather where water accidents are relatively likely to occur, victims floating on the sea are swept up, down, left and right by large waves. Although this is the case in many cases, the water rescue device of the invention of the present application has the effect of being able to rescue victims by using the net-like body by easily pulling the towing net not only vertically but also horizontally.

In addition, the rescue device of this invention was dropped and hung on the water surface near the position of the disaster victim floating on the water surface using a helicopter, etc., and the rescue worker and pilot on the helicopter communicated with each other and rescued the disaster victim. By moving the helicopter after confirming that the position of the net and the towing net are appropriate,
The net is pulled through the suspended tow net, and once the victim is scooped up by the net, the helicopter is raised to an appropriate height and the tow net begins to roll up, which has the effect of scooping up the victim from the water surface. Since there is no need for the auxiliary rescuer to jump down to the sea surface and rescue the rescuer, there is an effect of preventing the auxiliary rescuer from suffering double injuries.

Furthermore, when the net is pulled up from the sea surface, the towing net that goes around the periphery of the net is combined with the weight of the victim and the squeezing action of the ring weight to release the net surrounding the victim. This has the effect of narrowing the mouth and pulling the mouth upwards safely and reliably.

In addition, since there is only one towing net at the water surface position where the net is located, even if the net hits the victim during towing, the victim's position will not shift, and the result will be the net This has the effect of preventing disaster victims from leaving the area covered by the body.

Furthermore, even if the rescue device of the invention of this application is dropped from a helicopter, the drop position may be shifted due to the effects of wind, etc., and as a result, the rescue device may be dropped on the opposite side of the intended drop surface near the victim. , the net can be used reliably by flying the helicopter in the opposite direction to the direction originally thought, and the rescue effect is the same no matter which direction the net is towed. , there is no need to re-drop it again, which has the effect of greatly increasing efficiency.
