However, due to the large area of the reservoir, it is difficult to manage, often someone deliberately climbs over the guardrail and enters the reservoir to play, and it is easy to cause the drowning accident. Since the reservoir slope concrete is soaked by water for a long time, the dregs or moss are attached to the slope drawdown zone, and it is very smooth, so the person falling into the water is difficult to leave the water surface by climbing the slope, and it is difficult to rescue or self-rescue. The Japanese patent with the publication number JP3131202U discloses the falling lifesaving net for keeping the slope landscape, which provides the climbing support point for the person falling into the water by laying the lifesaving net on the slope, and it is helpful to leave the water surface. In fact, the lifesaving net is attached to the water surface side of the reservoir slope concrete, and the lifesaving net is small in diameter, so it is difficult to provide the effective support or force point for the feet of the person falling into the water, and it is usually necessary to separate the lifesaving net from the slope by the toes at a certain distance, and then the feet are further inserted to make the lifesaving net support the soles, so that the feet can be stably supported to climb to avoid the secondary falling. However, since the lifesaving net has the counterweight at the bottom, the part above the water surface is more closely attached to the slope, so it is very difficult to separate the lifesaving net from the slope by the toes.
