Bionic swimming propeller and swimming propelling method

Abstract

The invention relates to a bionic swimming propeller and a swimming propelling method, and belongs to the technical field of swimming equipment and swimming propelling methods. According to the technical scheme, a plurality of longitudinal grooves (8) are formed in the surface of a base body (1), and corresponding shaft holes are formed on the inner walls on the two sides of each groove; a pull rod (3) is arranged in each groove, is embedded in the groove and slides up and down in the groove, one end of each pull rod penetrates out of the upper portion of the base body and is sleeved with a spring (5), and each pull rod is provided with a plurality of transverse grooves (6); a connecting shaft (7) is arranged on each scale (2) and located above the corresponding groove in the corresponding pull rod, and the two ends of each connecting shaft are clamped in the shaft holes in the corresponding groove of the base body; a bottom ring (4) is arranged below the base body and matched with the base body in shape. The bionic swimming propeller simulates the structure of scales and is simple in structure, convenient to use and practical, the bionic swimming propeller is tied to the crus when a user swims, and the scales are opened when the user drives the legs, so that the action area between the crus and water is increased; the scales are closed when the user withdraws the legs, so that advance resistance is reduced, and then swimming speed is increased.

Description

technical field [0001] The invention relates to a bionic swimming propeller and a swimming propulsion method, belonging to the technical field of swimming equipment and swimming propulsion methods. Background technique [0002] Swimming like a fish in water is a human dream. When people swim, they mainly rely on the upper arm swing and the reaction force generated between kicking and the water to move forward. Due to the particularity of the human body structure, the swimming speed of people in the water is limited. The functional area of ​​the body is wide, but at the same time it also restricts other functions of the hands and feet. At present, the propeller used to help speed up swimming in the background technology, such as Chinese invention patent application 2013107428326, "a swimming propeller", uses batteries, motors, propellers, etc. for auxiliary propulsion. The structure is complex, the cost is high, and additional batteries are required as Power: Invention pate...
