<p>Disclosed is a rope-controlled aquatic life-saving apparatus, comprising a life-saving float body (1), a guiding rudder plate (2) and a rescue rope (6), wherein the guiding rudder plate (2) has a pressure-bearing upstream face. When the rope-controlled aquatic life-saving apparatus is used on the water, the life-saving float body (1) floats on the surface of the water, the guiding rudder plate (2) is provided on the life-saving float body (1) and is at least partially submerged in the water, the included angle between the pressure-bearing upstream face and the surface of the water is between 30° and 150°, one end of the rescue rope (6) is connected on the life-saving float body (1) and the other end of the rescue rope (6) is held by a rescuer. By providing the guiding rudder plate (2) on the life-saving float body (1), the force of impact of the water current is used to navigate the life-saving float body (1) to a required position on the water to enable the person being rescued to grab on. The rope-controlled aquatic life-saving apparatus has a simple structure, is low cost and is convenient to put into effect, can be individually and flexibly operated by a user, and has strong applicability.</p> |
