Mask-the window to enjoy the underwater world is worn on the face, covering the eyes and nose. Its main functions are: 1. It enables divers to observe the scenery in the water clearly. 2. Prevent nasal congestion and balance ear pressure. Diving goggles consist of lenses, frames, skirts and headbands. Different from goggles, professional goggles lenses are made of pressure-resistant toughened glass with the word "toughened" printed on it, which is very different from ordinary goggles. Diving goggles have a nasal sac for balancing pressure, which can prevent water from entering the nasal cavity. According to the degree of the eyes, the vision orthodontist can wear a diving mirror that suits him, and it is best not to wear contact lenses. The object seen through the diving mirror underwater is 0.33 times larger than the actual size. The most important thing to choose is to fit and suit your face. Breathing tube-used when snorkeling on the surface of the water, so that people can breathe without leaving their heads out of the water; In scuba diving, divers can breathe through the breathing tube when resting or swimming on the water surface to save air in the gas bottle. Structurally, breathing tubes can be basically divided into two types: drain valve type and non-drain valve type. From the modeling point of view, there are L-type, J-type, C-type, G-type and so on. The length is generally about 42cm, and the caliber is 2-2.5cm. When choosing a breathing tube, you should pay attention to: the occlusion should be comfortable, otherwise it will cause mandibular fatigue. Fin-provides powerful forward power, gives you a pair of wings that "fly" in the ocean, also called frog shoes, and provides power for divers to move forward underwater. Different from swimming, diving only depends on the movement of legs, while hands are usually used to do other things (such as underwater photography and manipulating other instruments and equipment). ). According to different purposes and designs, it can be divided into two types: sleeve foot type and adjustable type. Foot-cover diving boots don't need to be worn, just press the number barefoot; Adjustable flippers need special diving boots. Excerpt from China diving equipment network

The basic meaning of diving

Drifting to the bottom of the sea is a long-standing wish of people. As early as 2,800 years ago, in the heyday of Mesopotamia, the armies of the Azria Empire washed the air with sheepskin bags and attacked the enemy from the water. This may be the ancestor of diving. In 1700 years ago, in China's history book "Biography of Japanese in Wei Zhi", there were already records of fishermen diving and fishing in the sea. At 1720, an Englishman dived to a depth of 20 meters with a custom-made wooden bucket and successfully salvaged the seabed. Today, the predecessor of professional diving is 160 years ago, the mechanical diving invented by Guo Mengbei in Britain to transport air from a water pump, that is, helmet diving. This kind of diving first appeared in Japan at 1854. 1924 glass is used as a diving mirror, and a mask submersible is used to suck air from the water. This is the predecessor of scuba diving equipment. In this year, the Japanese used a mask submersible to dive 70 meters to the bottom of the Mediterranean Sea, and successfully picked up the gold nuggets in the sunken ship Yasaka, which shocked the world. During World War II, a special military "air-hood submersible" was developed, which adopted a closed circulation device with an air bottle. At the end of World War II, France developed an open-air submersible, which was very popular in Europe and America around 1945. In recent years, due to the progress of diving equipment, diving has flourished, and more and more people have participated in diving and liked diving. With the popularity of diving all over the world, entering the underwater world is no longer a fairy tale wish, but a romance that surprises you. You can feel the novelty of diving in real waters without learning to dive in advance. Imagine that when you slowly dive into the cool water of Ming Che, the sunlight is refracted by the water into countless stars, which keep flashing and shining before your eyes. When colorful fish snuggle up to you, you will be delighted to feel that you are in a wonderful and novel world and appreciate colorful underwater creatures; Like a string of bubbles, you will be surprised to find that you are flapping your flippers easily and floating freely in the water, and truly realize the wonder, romance, freedom and happiness of the underwater world. The benefits of diving are not only the great enjoyment brought by the strange world in water, but also the improvement of human heart and lung function. In the United States and Japan, diving is even used as an auxiliary means to treat cancer. According to scientific proof, the balanced pressure of water on human body is helpful to blood circulation, and long-term oxygen inhalation under water can effectively kill cancer cells and inhibit their spread. But because of the high cost of diving, most people can't afford it. Although the basic training fee is only about 2000 yuan, not everyone can digest the equipment and travel expenses that follow. A good set of equipment, ordinary 20,000 to 30,000, advanced10,000. If you want to go to a good natural sea area, there are Malaysia and Thailand nearby and Australia and the Red Sea in the distance. For an object placed in water, the buoyancy it receives is equal to the weight of the water it displaces. If the weight of water displaced by an object in water is greater than the weight of the object itself, the object will float on the water surface, which is called positive buoyancy. Conversely, sinking is called negative buoyancy. If the weight of the water discharged by an object is equal to the weight of the object itself, the object will be suspended in the water to achieve neutral buoyancy. When diving, it is very important to learn to control the buoyancy on the surface and bottom. For example, when resting on the water, positive buoyancy can save physical strength, while when underwater, you need to maintain neutral buoyancy most of the time, so that you can swim freely in the water, maintain good visibility and avoid hurting you and fragile creatures in the water. Divers can adjust buoyancy by counterweight, buoyancy control device (BC) and breathing depth. Necessary learning for diving in the sea: including the use of breathing tubes and regulators, water rest methods, emergency handling and so on. Preparation before entering the water is very important. Check whether the equipment function is normal by yourself, and then check each other between peers. Entry posture: dive straight ahead-the water depth should be above 1.5m, with your feet spread back and forth, with one hand pressing the mask and the other pressing the cylinder belt. Sit with your back to the water-sit in the boat face in and dive on your back. Sit in the water-suitable for beginners. Go sideways into the water-then float on the rubber boat and roll into the water. Diving: B.C. (Buoyancy Regulator) method-Buoyancy Regulator, with counterweight belt, diving from head to toe. No, BC-head, feet. Rising: the rising speed should be controlled within18m per minute, in short, it should not exceed the rising speed of bubbles exhaled by yourself; Don't stop breathing; rise ......
