Problems solved by technology

[0005] For the main propulsion tools of current swimming equipment and diving equipment, the bi-feet bi-fins and bi-foot mono-fins have not solved the natural movement structure defect that the human body is not suitable for efficient swimming in water, that is, it is difficult to achieve high-speed and fast swimming. Swimming and low-speed slow swimming can obtain higher propulsion efficiency and cannot realize deficiencies such as flexible steering and direction fine-tuning correction. The process is carefully observed and studied, and compared with the posture of humans imitating dolphins and cetaceans swinging their tail fins in the water, comparing the differences between the two, and then analyzing the reasons for the differences in detail, combined with the characteristics of human body movement structure, Through the scientific and reasonable use of ergonomics, a steerable and variable speed cruising equipment system including an electronic control device is provided. With the help of the steerable and variable speed cruising equipment system including an electronic control device, swimmers can swim through water according to their swimming speed. Turn the left and right ankles, that is, do the action of straightening the instep or hooking the feet, and adopt the electric control force transmission method or the pure mechanical force transmission method to adjust the corners of the left tail fin and the right tail fin of the bionic variable tail fin device respectively, so as to realize the fin extension. Width and fin area can be adjusted or flexible steering and direction fine-tuning can be realized. At the same time, the elastic force of the knee elastic element can also be adjusted, so as to achieve high-speed swimming at a higher frequency and a lower frequency. Swimming at low speed and slowly, no matter what frequency is used to kick water, the swimmer can effectively increase the proportion of useful work, and maximize the forward efficiency and swimming speed of swimming and diving. In the process of swimming, when it is necessary to turn or When the direction deviates, adjust the corners of the left and right tail fins asynchronously to realize real-time flexible steering or direction fine-tuning correction, fully exert the swimming potential of the swimmer in the water, and finally achieve the purpose of long-distance continuous cruising; swimmers cruise through variable speed , can also effectively reduce the feeling of fatigue during long-distance cruising; in addition, the direction of thrust generated by the steerable and variable-speed cruising equipment system including the electronic control device is exactly the same as the direction of swimmers' travel, thus overcoming the problem of double-finned or bipedal swimmers. Due to the angle between the leg and the fin caused by wearing the monofin on the swimmer's foot, the direction of the propulsion force generated by the fin hitting the water cannot be completely consistent with the swimmer's forward direction, thereby further improving the propulsion efficiency
