It is orange-red in color and facilitates water search and rescue. Its minimum buoyancy in operation is 8 kg, and it is worn around the waist.

[0003] With the development of science and technology and materials, various new types of water life-saving devices are emerging one after another. However, the effectiveness of water life-saving devices needs to be tested in practice to understand their effectiveness. To this end, a water life-saving device simulation test equipment and its use method are proposed. The equipment can simulate the marine water environment to test the performance of the water life-saving device, thereby determining its life-saving effect. The equipment is equipped with three groups of water reservoirs for storing water and storing the required amount of water according to the difficulty of the test. An electric opening and closing structure is provided for electric water release, and artificial test waves are created to test the life-saving performance of the water life-saving device.
