Dual-purpose equipment for swimming and diving

Abstract

The invention discloses a dual-purpose equipment for swimming and diving, which comprises a fixed-shaped cover and a flexible swimming trunk. The fixed-shaped cover covers the swimmer from the head to the torso, and the flexible swimming trunk covers the swimmer from the torso to the torso. The feet are connected to the swimmer's torso with a fixed-shape cover to form an integral structure, and at least one of the front and back sides of the swimmer's back or chest and abdomen is covered by the fixed-shape cover. The breathing tube is provided with elastic elements of the breathing tube so that it stands vertically on the fixed-shaped cover body. The front end of the fixed-shaped cover body covering the swimmer's head is provided with a buffer device, and the inside is lined with a buffer material in the cover. At least one pressurizing device is arranged between the fixed-shape cover body and the flexible swimming trunks and the swimmer's body, the fixed-shape cover body is equipped with a visual information collection device, and the tail end of the flexible swimming trunks is provided with a hoop fixed on the swimmer's legs or Bionic fin sealing ring in the ring groove of the bionic fin fixing rod between the feet.

Description

technical field [0001] The invention relates to swimming equipment and diving equipment industries, in particular to a dual-purpose equipment for swimming and diving, which is used for swimming and diving, and is especially suitable for long-distance high-speed cruising in relatively wide waters. Background technique [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 achieve a high swimming...

[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
