[0023] Example 1 A miniature cryogenic protection lifeboat, such as Figures 1 to 3As shown, it includes an air cushion, a buoy 1, a boat bottom 2, a boat awning 3 and an inflation system. The buoy 1 is arranged along the outer circle of the air cushion, the boat bottom 2 and the boat awning 3 are arranged on the upper end surface and the lower end surface of the air cushion respectively, the inflation system is arranged on the buoy 1, and a sandwich airbag structure is arranged on the boat awning; after being inflated by mouth, an air barrier can be formed between the inside of the boat and the external environment; according to the test results, in a low temperature and strong wind environment, the temperature inside the awning can be at least 4°C higher than that outside the awning.

[0024] Furthermore, the buoy 1 is a U-shaped air bag.

[0025] Furthermore, the main materials of the air cushion, buoy 1, boat bottom 2 and boat awning 3 are polyurethane tape; the air tightness and strength of the buoy can be ensured; the special-shaped buoy and the buoy in the buttocks seating area have a larger diameter, which can improve the riding comfort and floating stability, and provide support for the rescued persons to board the ship; a handle strap is provided on the buoy to facilitate the rescued persons to board the ship; an air blowing nozzle is provided on the inside of the buoy to facilitate the passengers to replenish air to the lifeboat; a safety valve is provided, and when the pressure in the buoy is too high, the safety valve opens for automatic pressure relief protection.

[0026] Furthermore, the airbag is formed by high-frequency heat-sealing of two upper and lower polyurethane tape pieces, which can ensure the air tightness and strength of the float.

[0027] Example 2 The inflation system is further limited on the basis of Example 1, and the performance of Example 2 after the limitation is even better.

[0028] Furthermore, the inflation system includes a carbon dioxide gas cylinder and an inflation device, and the carbon dioxide gas cylinder is connected to the buoy 1 through an inflation valve body.

[0029] Furthermore, a connecting belt is connected to the inflation valve body to form an inflation device. Pulling the connecting belt on the inflation device drives the rocker arm of the inflation valve body to rotate. The rocker arm pushes the striker in the inflation valve body of the inflation device to move forward, piercing the sealing cap on the carbon dioxide cylinder, and the carbon dioxide gas in the cylinder rushes out and enters the float. The carbon dioxide cylinder is a rigid bottle device filled with carbon dioxide gas. After the carbon dioxide cylinder is pulled out, the buoy is inflated to form the buoy for the rescued persons to board the ship.

[0030] Furthermore, a handle is provided on the buoy, arranged outside the boat cover 3, so as to facilitate the rescued persons to board the boat; An inner handrail 17 is provided on the air cushion or the boat awning 3 , and the inner handrail 17 is arranged inside the boat awning 3 .

[0031] Furthermore, the highest point of the awning 3 is close to one end of the air cushion, serving as the buttocks seating end. The diameter of the buoy at the buttocks seating end is larger than the diameter of the buoys on both sides of the air cushion, forming a special-shaped buoy, which can improve riding comfort and floating stability, and provide support for rescued persons to board the ship.

[0032] Furthermore, an air blowing nozzle is arranged on the inner side of the buoy to facilitate passengers to inflate the lifeboat; a safety valve is also arranged on the buoy, and when the pressure of the buoy is too high, the safety valve opens to automatically release pressure for protection.

[0033] Furthermore, the air cushion is connected to the buoy through a fixing loop, the air cushion is fitted to the bottom of the ship, the interior of the air cushion is heat-sealed and divided into multiple chambers, which are divided into diamond-shaped grids, and the chambers are connected to improve the overall strength of the air cushion, and a compartment is formed after inflation.

[0034] Furthermore, the air cushion and the bottom of the boat are both sunken triangular prisms, and the lower end of the air cushion is embedded in the bottom of the boat; the bottom of the boat is sealed by sewing three pieces together and then sealed by a heat-sealed sealing strip; the bottom of the boat is sewn on the inner rough edge of the piece under the buoy and then sealed by a heat-sealed sealing strip; The air cushion is composed of an upper piece assembly and a lower piece assembly. Both the upper piece assembly and the lower piece assembly of the air cushion are formed by heat-sealing three pieces of cut pieces to ensure that the appearance is the same as the bottom of the boat. The upper piece assembly of the air cushion and the lower piece assembly of the air cushion are heat-sealed. After the air cushion is sealed, diamond-shaped grids are heat-sealed inside to form compartments after inflation. The entire chamber is divided into many small chambers to improve the overall strength of the cushion.

[0035] Furthermore, air columns are distributed on the edges of the awning 3, and the air columns are used to quickly prop up the awning 3 after inflation. The awning 3 is a closed awning 3, and a zipper 11 is provided on the awning 3. The awning 3 can be entered by unzipping the zipper 11. The awning 3 is also provided with an observation window, and a water collector 9 is provided on the outside of the awning 3, and the water collector 9 is bonded to the awning 3. A water bag 12 is provided at the bottom of the air cushion, and the water collector 9 is connected to the water bag 12.

[0036] A lifesaving positioning light is arranged on the air cushion or the buoy, and the lifesaving positioning light is connected with a lifesaving positioning light battery.

[0037] The air cushion is provided with an inflator and a sponge 14, which are arranged in the awning. The inflator and the sea surface 14 can be connected to the handle or inner handrail on the air cushion through a pull rope. The lifeboat is connected to a sea anchor. The air cushion, the bottom of the boat and the air bags and air columns on the awning 3 can all be inflated by the inflator.

[0038] Working principle of the present invention: like Figure 1 As shown, the main body of the lifeboat is a U-shaped airbag structure, which consists of a tube, a boat bottom, an air cushion, a boat awning, an inflation system, a carbon dioxide cylinder, accessories and other structures. The buoy 1 is a special-shaped airbag structure; the boat bottom 2 is sewn on the inner raw edge of the lower cut piece of the buoy 1, and then sealed by a heat-sealed sealing strip; the boat awning 3 is sewn on the outer raw edge of the upper cut piece of the buoy 1, and then reinforced by an edge strip; the air cushion is fastened to the fixed loop on the inner edge of the buoy 1 by an edge rope; Furthermore, the inflation valve body is threadedly connected to the inflation joint to form a passage for the carbon dioxide gas to enter the float 1; Further, the carbon dioxide cylinder 4 is threadedly connected to the inflation valve body; When the lifeboat is in use, the connecting belt on the carbon dioxide cylinder 4 is pulled to drive the rocker arm on the inflation valve body to rotate, and the rocker arm pushes the striker in the inflation valve body to move forward, piercing the sealing cap on the carbon dioxide cylinder 4, and the carbon dioxide gas in the carbon dioxide cylinder 4 rushes out and enters the buoy 1, causing the buoy 1 to expand and form, generating buoyancy.

[0039] The personnel can grab the handle 16 to complete the boarding. After boarding, the personnel use the sponge 14 to drain the water seepage from the bottom of the boat; pull up the zipper 11 on the boat awning 3; use the inflator 14 to inflate the air cushion and the pillars on the boat awning 3. The personnel can observe the external environment through the observation window 8, and the water collector 9 completes the collection of fresh water such as rainwater. When the water surface is bumpy, it can be stabilized by the inner handrail 17. After the battery of the life-saving positioning light enters the water, the life-saving positioning light is turned on to indicate the position.
