Problems solved by technology

Thinking about and reviewing the disadvantages of swimming teaching, the common practice is to teach in traditional swimming pools. People don’t realize that the size of the pool is unreasonable. Drowning prevention, unable to fully and quickly understand the natural buoyancy of water in the human body, and may not be able to learn to swim in ten and a half months
[0003] Experiments have proved that: "ZL03123812.2 Learning Swimming Device" has a slow floating bottom and rising speed, and the emergency effect of avoiding drowning is obviously lagging behind. There is also the problem of cleaning the body of the water treatment module in "ZL201610538488.2 A fast-track device for swimming without drowning that simulates a river"

Embodiment 1

[0030] Such as figure 1 As shown, the student sits on the springboard 44 of the mobile diving platform with his back facing the deep water through the attached ladder 47, bends his knees and pushes the top edge of the shallow water end frame with his feet, and the mobile diving platform carries the student to slide to the deep water end in an instant, and stands on the mobile diving platform To the shallow water end frame plate 4, take a deep breath, hold your breath, pull-ups, and jump into the teaching area 31 for learning to swim and avoid drowning. After the feet touch the bottom, they must immediately float up and emerge from the water surface, and float to the inside of the shallow water end frame plate 4 with the clean water flow. Repeat this process, and you can fully and quickly realize the natural buoyancy of water in the human body, and learn to swim in half an hour.

Embodiment 2

[0032] Others are the same as in Embodiment 1. The student enters the teaching area 31 for swimming and avoiding drowning from the attached ladder 47 at the shallow water end frame plate 4 ends. Backing plate 18 is gripper, and both hands are alternately used, climbs to deep-water end frame plate 3 inner side, changes prone position to squatting position, both feet forcefully pedals the step at the bottom of the grate, the body must immediately float up and emerge from the water surface, immediately head backwards, Both arms swung towards the back, and the body must swim backstroke with the clean water current to the inside of the shallow water end frame plate 4, repeat this process, half an hour, dive, backstroke learned simultaneously.

Embodiment 3

[0034] Before learning to swim, students should learn not to pinch their noses with their fingers, and can hold their breath for ten seconds. Others are the same as in Embodiment 1 and Embodiment 2. The only difference is that the water pump 32 is turned off, the pool water is still, and the student's face is submerged in the water for ten seconds. Seconds, then leave the face from the water, take a quick breath, then immediately submerge the face into the water, hold your breath for another ten seconds, leave the face again, repeat this process, and breathe proficiently until you don’t choke the water. On the steps at the bottom of the waist grate, paddle freely with both hands, and experience the resistance of the water against the palm. The speed of paddling is different, and the resistance of the water is different. After realizing the resistance of the water, that is, the buoyancy of the water, students must face the shallow water end Frame 4, stand on the steps at the bot...

Abstract

The invention discloses an anti-drowning teaching aid for swimming learning. The anti-drowning teaching aid comprises a bracket oblique-bottom pool, grate bottom steps, a pure water flow and a movable diving platform, the grate bottom steps are located on the surface layer water surface of the bracket oblique-bottom pool, the pure water flow is located on the middle surface layer of the bracket oblique-bottom pool, and the movable diving platform stretches across left-right parallel tracks at the top of the bracket oblique-bottom pool. Through the grate bottom steps capable of floating upwards instantly, the drowning psychological fear of students is completely eliminated, appropriate water depth footholds for breaststroke learning and grips required for underwater swimming learning are provided for the students of different heights, and the students can fully and quickly comprehend that water has buoyancy naturally relative to a human body, and can learn swimming within half an hour. The anti-drowning teaching aid is simple in structure, proper, fine and low in manufacturing cost, is placed on the floor for use, is safe, reliable, perfectly safe, detachable and easy to assemble, and does not occupy a permanent site, it is ensured that pool water does not contain chlorine and approximates to high-quality mineral water, the pool water does not need to be replaced frequently, and water resources are greatly saved.

Description

technical field [0001] The invention relates to the field of swimming sports, in particular to teaching aids for learning to swim and avoiding drowning. Background technique [0002] On June 1, 2015, the ship "Oriental Star" capsized and sank in the Yangtze River, 442 people were killed, 13 swimmers survived, and there are so few swimmers! CCTV1 follow-up report: Every year, 380,000 people drown in the world, and my country accounts for 80,000 of them, most of whom are children. Thinking about and reviewing the disadvantages of swimming teaching, the common practice is to teach in traditional swimming pools. People don’t realize that the size of the pool is unreasonable. Drowning prevention, unable to fully and quickly understand the natural buoyancy of water to the human body, and may not be able to learn to swim in ten and a half months. [0003] Experiments have proved that: "ZL03123812.2 Learning Swimming Device" has a slow floating bottom and rising speed, and the eme...
