An electric heating diving suit

Abstract

The invention belongs to the technical field of underwater engineering technology equipment, and relates to an electric heating diving suit, which is composed of an upper clothing part, a lower clothing part and an electric heating system, and is based on an ordinary light diving dry diving suit, and uses a graphene-magnesium seawater battery or The lithium battery power supply device is used as the power supply, and the graphene flexible electric heating film is used as the electric heating element, so that the diver does not need to wear any cold-proof and warm clothing when diving in low-temperature waters. Staying underwater for more than 4 hours greatly improves the efficiency of underwater operations, avoids the harm of low temperature to the human body, eliminates the bloated clothing during underwater operations, and enables divers to move freely underwater, which greatly improves underwater operations. The accessibility effectively overcomes the disadvantages of complex clothing, poor thermal effect, bloated body, clumsy underwater activities, and short underwater stay time in the prior art, and has the advantages of convenient wearing, reliable use, good thermal effect, Advantages such as flexibility.

Problems solved by technology

[0002] Diving suits are dependent equipment that supports the life and underwater activities of divers. It is directly related to the life and health of divers and affects the freedom of divers' underwater activities, especially dry working diving equipment. An important guarantee for diving safety and health, underwater stay time and work efficiency. Marine resource development, underwater engineering construction, underwater facility equipment maintenance, hull inspection or troubleshooting, especially underwater rescue and emergency rescue, all require divers to operate at low temperature. For diving operations in water areas, the existing diving suit itself does not have the function of keeping warm. When diving in low-temperature waters, divers can only wear thick cotton-padded clothes or sweaters to keep warm. Freedom of underwater activities while constraining the accessibility of underwater operations

The dry thermal diving suit disclosed in Chinese patent 201210374982.1 is made of several pieces of waterproof fabrics bonded and sewn together. It is provided with a head outlet and a hands outlet. The diving suit is also provided with at least one opening on its surface. To close the zipper, one end of a rubber sheet tube goes deep into the opening, and the peripheral edge of the end is glued to the edge of the opening, and the other end of the rubber sheet tube is provided with a tie rope. When the rubber sheet tube enters the opening completely, the The zipper is closed inside the diving suit, and the diving suit is provided with outlets for both feet. The diving suit also includes diving boots integrated with the bottom of the trouser legs. The opening includes a wearing port arranged on the front chest of the diving suit. And the urination opening of the trousers door position, a thermal insulation baffle is also provided in the described opening, the upper edge of the thermal insulation baffle is bonded to the inner surface above the opening of the diving suit, and the thermal insulation baffle connects the rubber sheet tube with the space in the diving suit Separated, the material of the thermal insulation flap is consistent with the waterproof fabric material of the diving suit, the zipper is an ordinary plastic zipper or metal zipper, and the diving suit is made of several pieces of waterproof fabric bonded and sewn, and the diving suit is sewn together. The inner and outer surfaces of the thread are respectively covered with a layer of rubber sheet, and the waterproof fabric is divided into three layers, the middle layer is foamed neoprene, and a layer of nylon cloth is respectively coated on both sides of the neoprene; it is affected by the structure of the diving suit. Restrictions, unable to wear thicker warm clothing, seriously affect the health of divers, seriously restrict the length of time divers stay underwater and the efficiency of underwater work

At the same time, the manufacture of electric heating diving suits requires small size, high efficiency, safe and reliable power support. In the prior art, the lithium battery most likely to be used for the power supply of electric heating diving suits has some irreversible defects. First, the maintenance is complicated. Lithium batteries Charge and discharge maintenance needs to be carried out every three months; second, there are many potential safety hazards. Lithium batteries have been listed as corrosive, flammable and explosive products. Many countries have made clear restrictions on the use, carrying, transportation and storage of lithium batteries Third, it is difficult to support the power and time required for the heating of the diving suit under the condition of the battery volume and weight
