Swimming and diving dual-purpose appliance

Abstract

The invention discloses a swimming and diving dual-purpose appliance, which comprises a fixed-shape cover body and flexible swimming trunks, wherein the fixed-shape cover body covers a swimmer from a head part to a trunk part; the flexible swimming trunks cover the swimmer from the trunk part to foot parts and is connected with the fixed-shape cover body to be of an integral structure at the trunk part of the swimmer; at least one side of the front and rear sides, which cover the back part or the thoracoabdominal part of the swimmer, of the fixed-shape cover body is provided with a breathing pipe hinged onto the fixed-shape cover body, and is provided with a breathing pipe elastic element to make the breathing pipe vertically erected on the fixed-shape cover body; the front end of the part, which covers the head part of the swimmer, of the fixed-shape cover body is provided with a buffering device; an in-cover buffering material is laid and lined inside the fixed-shape cover body; at least one pressurization device is arranged among the fixed-shape cover body, the flexible swimming trunks and the body of the swimmer; the fixed-shape cover body is provided with a visual information collecting device; the tail ends of the flexible swimming trunks are provided with bionic caudal fin sealing rings which are bound in an annular groove of a bionic caudal fin fixing rod fixed between two legs or two feet of the swimmer.

Description

technical field [0001] The invention relates to the swimming equipment and diving equipment industries, in particular to a swimming and diving dual-purpose equipment, which is used for swimming and diving, and is especially suitable for long-distance high-speed cruising in relatively broad waters. Background technique [0002] In contemporary society, swimming and diving are becoming more and more popular, and various swimming equipment and diving equipment are emerging in an endless stream. It is a common combination to use diving suits with fins and respirator, which can not only swim on the water, but also sneak underwater. , The fins include double fins with alternating feet for kicking water, and single fins with double feet for kicking water simultaneously, but in general, the propulsion efficiency is not high, and a considerable proportion of the swimmer's physical energy is consumed in useless work. It is difficult to achieve a high swimming speed, and if the distanc...

[0002] In contemporary society, swimming and diving are becoming more and more popular, and various swimming equipment and diving equipment emerge in an endless stream. It is a common combination to use diving suits with flippers and respirators, which can swim on the water or sneak underwater. , the flippers include double-footed bi-fins that use both feet to fetch water alternately, and double-footed mono-fins that use both feet to fetch water synchronously, but overall, the propulsion efficiency is not high, and a considerable proportion of swimmers' physical energy is consumed doing useless work In terms of speed, it is difficult to reach a high swimming speed, and you will feel tired when the distance is a little longer, so it is impossible to achieve long-distance high-speed cruising

[0003] The reasons for the low propulsion efficiency mainly come from three aspects. First, the existing diving suits are designed according to the shape characteristics of the human body. Although they can better match the human body shape and are more comfortable to wear, they are not suitable for swimming in water The principle of the least linear forward resistance is far from the body shape of whales, sharks, and dolphins; the second is the propulsion tool, that is, the propulsion efficiency of flippers is not high. The propulsion efficiency of bipedal monofin is higher than that of bipedal fins that use alternate feet to fetch water, but there is still a big gap compared with the tail fins of whales, sharks, and dolphins; finally, human bones and muscles are used to adapt Humans exist for walking and running on land, while the bones and muscles of whales, sharks, and dolphins exist to adapt to efficient swimming in water. Therefore, humans are far behind in terms of swimming form and muscle strength. gave the latter
