Embodiment 1

[0015] The main structure of the low-voltage electric heat preservation type lifejacket involved in this embodiment includes: a back skirt lining 1, a rear skirt clothing surface 2, a left front clothing lining 3, a left front clothing surface 4, a right front clothing lining 5, a right front clothing surface 6, and a left warm Sleeve lining 7, left thermal sleeve sleeve surface 8, right thermal sleeve sleeve lining 9, right thermal sleeve sleeve surface 10, thermal hat hat lining 11, thermal hat hat surface 12, first electric heating film 13, second electric heating film 14, The first ventilation hole 15, the second ventilation hole 16, the third ventilation hole 17, the fourth ventilation hole 18, the fifth ventilation hole 19, the sixth ventilation hole 20, the wire hole 21, the back flap 22, the third electric heating film 23, Left front flap 24, fourth electric heating film 25, right front flap 26, fifth electric heating film 27, thermal cap 28, left thermal sleeve 29, rig...

Embodiment 2

[0019] The main structure of the low-voltage electric heating thermal lifejacket involved in this embodiment is the same as that of Embodiment 1, and its circuit working principle is the same as that of Embodiment 1. Five electric heating films are selected to be connected in parallel and then connected in series with seawater batteries and thermostats to form a closed loop. The power is 15W, the total power is 5×15W=75W, the working voltage is 6V-4V, the working current is 75W / 6V=12.5A, the battery capacity is 12.5A×4h=50Ah, the wire cross-sectional area is 3.0mm 2 ; Open the sealing cover of the disposable seawater battery and follow the seawater into the battery, the battery will be activated, and it will start to supply power after 1-2 minutes to heat the lifejacket. Under the condition of water temperature of 15℃, the temperature of the heating surface of the lifejacket and the human body will be kept at 30℃ automatically through the thermostat. --35°C, the temperature of ...

Embodiment 3

[0021] The basic structure and electrical principle of the low-voltage electric heating thermal lifejacket involved in this embodiment are the same as those of Embodiment 1. Three upper buttons 40 are also provided on the thermal hat surface 12 of the thermal hat 28, and the upper button 40 is provided on the back skirt surface 2. The three lower buttons 41 that match the buttons 40; when the thermal cap 28 is not used, the thermal cap 28 is folded from the neckline of the lifejacket to the back, and the upper button 40 and the lower button 41 are fastened and fixed; the thermal cap 28 is used or used as buoyancy When the air pillow is used, the center of gravity of the low-voltage electric thermal life jacket is located at the lower part of the back flap 22, which can ensure that the person who falls into the water floats on his back. 29 and the right warmer sleeve 30 adopt the non-inflatable double-layer structure of the fattening sleeve.

Abstract

The invention belongs to the technical field of marine lifesaving equipment, and relates to a low-voltage electric heating warm-keeping lifejacket. The chest and the back waist of a single piece in the back skirt are respectively glued and inlaid with a first electric heating film and a second electric heating film, and the left side of the second electric heating film is glued together. For the thermostat with wires, a third electric heating film is glued and inlaid on the left front chest of the left front jacket, and a fourth electric heating film is glued and inlaid on the right front chest of the right front jacket, and the hat is placed on the inside of the thermal hat. The middle of the back of the head on one side of the expansion layer is glued and inlaid with a fifth electric heating film, the waist and the neck of the thermal hat, the cuffs of the left thermal sleeve and the right thermal sleeve are respectively equipped with built-in fastening belts, and the thermal cap of the thermal cap There is also an upper button on the top, and a lower button on the back of the garment; it is powered by a low-voltage battery to heat and keep warm in a low-temperature environment, and to improve the chances of survival of people who fall into the water; the overall structure is simple, safe and reliable, and the heating voltage is low, keeping warm The effect is good.

Description

Technical field: [0001] The invention belongs to the technical field of marine lifesaving equipment, and relates to a low-voltage electric heating warm-keeping lifejacket, in particular to a lifejacket that can provide heating and warmth for shipwrecked personnel in low-temperature sea areas. Background technique: [0002] With the vigorous development of marine traffic, as well as the continuous extension of marine scientific research and marine resource development activities, accidents of shipwrecks and marine operators accidentally falling into the water occur from time to time, and life jackets are one of the necessary items for people who go to sea. Wearing a life jacket when an accident occurs can Effectively prevent drowning death; however, according to authoritative data, ordinary people will die after 10-20 minutes in seawater with a water temperature of 5-15 ° C and similar air temperature conditions due to physiological disturbances and loss of consciousness. --5...
