Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the utility model provides a quick lime life vest that generates heat, including life vest main part 1, 1 two shoulders department of life vest main part is equipped with reflecting plate 10, 1 chest department of life vest main part is equipped with lifesaving whistle 11, the inside of life vest main part 1 is equipped with buoyant device 2 and heats device 3 from outside to inside in proper order, it includes inner wall 6 and outer wall 7 to heat device 3. The cross section of inner wall 6 and outer wall 7 is the elliptical arc, outer wall 7 closely laminates with buoyant device 2, inner wall 6 and human direct contact, the inside of heating device 3 is equipped with quick lime 5 in bags and a small amount of air, quick lime 5 in bags is fixed at outer wall 7 inboardly and is higher than 3 bottoms 4cm of heating device according to certain interval. The lower part in the 1 outside of life vest main part is equipped with into water button 4, the positive top of outer wall 7 is equipped with water inlet 8, water inlet 8 is connected with into water button 4 with the help of inhalant canal 13, the top at the outer wall 7 back is equipped with pressure valve 9.
The circumference of the heating device 3 is designed to be close to the chest circumference of an adult, the circumferences of the outer wall 7 and the inner wall 6 are 136 +/-3 cm and 108 +/-2 cm respectively, the height of the heating device 3 is 25 +/-1 cm, the heating device 3 is thin before water enters, the water level of the heating device 3 is 20 +/-1 cm after water enters, the thickness of the heating device is 7.5 +/-0.5 cm, and the seawater occupies 80 +/-5% of the volume of the heating device.
The button 4 of intaking is controlling the closure and the opening of water inlet 8, quilt under the normal condition the tight parcel of water proof membrane 12, simultaneously water inlet 8 is the closure state, tearing water proof membrane 12 back, clockwise rotation the button 4 of intaking is used for opening water inlet 8, anticlockwise rotation afterwards the button 4 of intaking is used for closing water inlet 8. After the water inlet 8 is opened, under the action of pressure, about 12L of seawater quickly flows into the heating device 3 and reacts with 4kg of bagged quicklime 5 in total to generate a violent chemical reaction, and the seawater in the heating device 3 is raised to 75-80 ℃ so as not to boil. The heating device 3 is made of silica gel or PVC and the like, so that the highest temperature range sensed by a person falling into water is 45-55 ℃. The pressure valve 9 is a one-way valve which only can not be opened, so that the air expanded by heating can be removed.
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 and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
