Description
Technical Field
The invention belongs to the technical field of life jackets, and particularly relates to a quicklime heating life jacket and a using method thereof.
Background
The risk of the ship being difficult to escape when sailing on the water surface. Far, the Tatannik number sinks when hitting the iceberg, and in recent years, the accident of sinking ships, such as eastern star, often happens. Studies have shown that human survives less than 15 minutes in 0 ℃ seawater. If the rescue ship can not arrive quickly due to a ship sinking accident at night or in the open sea and the water temperature is lower in a specific season with higher latitude, the drowning person can not escape due to the low-temperature effect even if wearing the life jacket to avoid drowning.
Therefore, the life jacket with the heating function is designed, the time for the drowning person to wait for rescue is effectively prolonged, and the survival probability of the drowning person is improved. In the prior art, a warm-keeping life jacket (patent number: 201420629866.4), a luminous automatic warm-keeping life jacket (patent number: 201720183487.0) and an automatic heating jacket type life jacket (201910139354.7) have heating functions, but have the defects of complex operation, high manufacturing cost and high uncertainty respectively.
Disclosure of Invention
The invention aims to provide a quicklime heating life jacket and a using method thereof, and aims to solve the problems of complex operation, high manufacturing cost and high uncertainty in the existing heating life jacket.
In order to achieve the purpose, the invention provides the following technical scheme:

When the quicklime heating life jacket is stored daily, the quicklime heating life jacket needs to be placed in a dry and closed space, and is strictly moisture-proof and damp-proof.
According to the experiment of 'relationship between the survival time of the drowner and the water temperature' made in the United states and Germany, the survival time of the drowner with the water temperature of 25 ℃ and 20 ℃ is 24 hours and 14 hours respectively. Therefore, we take 20 ℃ as the reference temperature and the time until the heating apparatus 3 starts to react until the temperature of the inside water drops to 20 ℃ as the continuous heating time.
In the experiment, the heating device 3 is placed in an experiment pool with the water temperature of 0, 2.5, 5, 15 and 20 ℃, and the water inlet button 4 is opened to enable a large amount of water to enter and then close the water inlet channel. The time taken for the water temperature inside the heating means 3 to drop to 20 c is then recorded, called the duration of heating. The results of the experimental recordings are as follows:
Therefore, the heating life jacket can provide the drowning person with continuous heating time of 0.5-4 hours. Under the condition of water temperature of 0-2.5 ℃, the survival time of a person falling into water is prolonged by 1-2 times, and the person stays in cold water for more than 45 minutes, so that the survival probability is improved; under the condition of water temperature of 5-10 ℃, the survival time of a person falling into water is prolonged by 48-90 minutes, the person can insist for 2 hours to 4.5 hours, and the survival probability is higher; particularly, under the condition of water temperature of 10-20 ℃, the survival probability of the drowning person is extremely high due to the long survival time of the drowning person and the continuous heating time of at least more than 1.5 hours.
The working principle is as follows: when the quicklime heating life jacket is used, after the waterproof protective film 12 is torn off, the water inlet button 4 is rotated clockwise firstly to enable a large amount of seawater to enter the heating device 3 through the water inlet 8, then the water inlet button 4 is rotated anticlockwise to prevent the seawater from continuing to enter, the seawater and the bagged quicklime 5 generate violent chemical reaction to heat the seawater, the heated seawater continuously transfers heat to a human body through the inner wall 6, and excessive hot gas generated in heating is discharged from the pressure valve 9.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
