Description

TECHNICAL FIELD

[0001] The present application relates to the field of lifesaving equipment, in particular to a directional floating lifesaving device. BACKGROUND

[0002] At present, the most common water lifesaving equipment is lifebuoy, which is usually made of cork, foam plastic or other light materials with smaller specific gravity, and is wrapped with canvas or plastic. When the lifebuoy is placed in water, it will float on the water surface, and the fallen person can rely on the buoyancy provided by the lifebuoy by grabbing it. Therefore, the key to whether the lifebuoy can play a role lies in whether the fallen person can grab it. In actual rescue work, the lifebuoy often needs to be thrown to the fallen person by the rescuer, but due to the limited throwing distance of the rescuer, the rescue distance is also limited. When the fallen scene is a wide river, it is difficult for the rescuer on the shore to throw the lifebuoy to the center of the river. Moreover, even if the throwing distance of the rescuer can reach the position of the fallen person, the accuracy of the throwing of the rescuer is also crucial. Only by accurately throwing the lifebuoy to the fallen person can the fallen person grab it in the first time, so that the lifebuoy can play a role effectively. Otherwise, the lifebuoy will be washed away by the water flow. Moreover, even if the throwing of the rescuer is accurate, the fallen person cannot grab the lifebuoy in the first time, and the lifebuoy will also be washed away, resulting in that the lifebuoy cannot play a rescue role effectively.

[0003] In view of this problem, with reference to Figure 1 A controllable lifebuoy is disclosed in Chinese Utility Model Patent No. CN2335887Y, which is composed of a remote control boat 1, a rope shaft 2, a rope directional ring 3, a traction rope 4, a traction ring 5, a guide water head 6, a life belt 7 and a lifebuoy main body 8. The rope shaft 2 is installed at the rear of the remote control boat 1, and the rope directional ring 3 is provided at the most tail end of the remote control boat 1. The traction rope 4 passes through the rope directional ring 3 and is wound on the rope shaft 2. The other end of the traction rope 4 is hung on the traction ring 5 of the guide water head 6, and the guide water head 6 is bonded to the side wall of the lifebuoy main body 8. In use, the remote control device controls the remote control boat 1 to rush to the fallen person, so that the fallen person can grab the lifebuoy main body 8. On the one hand, the lifebuoy main body 8 can be pulled to a position at a long distance by the traction of the remote control boat 1, so as to realize rescue at a long distance and overcome the limitation of the rescue distance by the throwing distance of the rescuer. On the other hand, the remote control device can control the remote control boat 1 to accurately rush to the fallen person with the lifebuoy main body 8, so as to overcome the influence of the water flow on the position of the lifebuoy main body 8.

[0004] However, one of the main reasons for the wide application of lifebuoys is that they are relatively cheap compared to other life-saving devices and suitable for large-scale deployment. The installation of remote control boats will significantly increase the cost of individual lifebuoys, and limited funds cannot be used to pre-deploy the remote control lifebuoys on the water side. The remote control lifebuoys cannot be placed outdoors for a long time due to the maintenance needs of the remote control boats, and it is difficult to act in time in an emergency. At the same time, the remote control boat also depends on the operation of professional rescue personnel, and ordinary people cannot operate the remote control lifebuoy at any time to carry out rescue work in an emergency. Therefore, even if the above patent has been disclosed since the end of last century, the common life-saving device on the market is still an ordinary lifebuoy. In the face of a long distance rescue, it still needs to rely on the surrounding swimmers to carry out rescue work, and the rescue personnel carry the lifebuoy to the swimmer by swimming around the swimmer. On the one hand, it increases the uncertainty of rescue, and on the other hand, it threatens the safety of the rescue personnel. SUMMARY

[0058] Specifically, referring to the drawings of the specification of the present application Figure 2 , the principle structure of the directional floating life-saving device is shown, wherein the directional floating life-saving device comprises a floating body 10 and a current rudder fin 20, wherein the directional floating life-saving device has a breaking flow direction, corresponding to the directional floating life-saving device being placed in water and forming water flow based on the relative motion with water, the directional floating life-saving device can be adjusted in the breaking flow direction against the flow under the action of the water flow, wherein the current rudder fin 20 protrudes from the bottom surface of the floating body 10 in a state inclined to the breaking flow direction, so as to correspond to the current rudder fin 20 generating a lateral directional floating force towards the breaking flow direction under the impact of the water flow when the directional floating life-saving device is placed in water and forms water flow based on the relative motion with water in the breaking flow direction, thereby realizing directional floating under the action of the water flow.

[0059] Corresponding to Figure 2 shown, when the directional floating life-saving device is placed in the water flow, under the impact of the water flow, the breaking flow direction of the directional floating life-saving device is opposite to the direction of the water flow, and with the impact of the water flow on the current rudder fin 20, the current rudder fin 20 will generate a guiding force F1, the water flow on the directional floating life-saving device will generate a water flow pushing force F2 in the same direction as the water flow direction, and the water flow flowing on both sides of the directional rudder fin 30 can avoid the directional floating life-saving device from being deflected, and the directional floating life-saving device will be oriented to float in the direction of the directional floating force F0 under the action of the directional floating force F0.
