DETAILED DESCRIPTION

[0032] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] As shown in the figure, the present invention discloses a U-shaped automatic lifesaving device with a pop-up inflatable cushion, comprising a lifebuoy body 1, in which an emergency mechanism is installed in the inner cavity of the lifebuoy body 1;

[0034] The emergency mechanism comprises an electric push rod 2, an electric box 3, a first wire 4 and a second wire 5. The electric push rod 2 is fixedly arranged at the bottom of the inner cavity of the lifebuoy body 1. A push rod 6 is fixedly connected to the left output end of the electric push rod 2. An iron ball 7 is fixedly arranged at the left end of the push rod 6.

[0035] The first wire 4 and the second wire 5 are both fixedly placed inside the electric box 3, wherein the first wire 4 is connected inside the electric box 3, and the second wire 5 is disconnected; an opening is opened on the right side of the electric box 3, and the iron ball 7 passes through the opening and enters the electric box 3;

[0036] A connecting tube 8 is fixedly installed and penetrated on the right side of the lifebuoy body 1, the right ends of the first wire 4 and the second wire 5 both penetrate the left inner wall of the inner cavity of the connecting tube 8, and a resistance wire 9 is fixedly connected between the right ends of the first wire 4 and the second wire 5, and a solid guanidine nitrate 10 is wrapped outside the resistance wire 9, and a safety airbag 11 is fixedly arranged on the right end of the connecting tube 8;

[0037] Specifically: the electric push rod 2 utilizes the push rod 6 to drive the iron ball 7 to enter the interior of the electric box 3 from the opening on the surface of the electric box 3. Since the iron ball 7 is conductive, the iron ball 7 connects the second electric wire 5 together, and the resistance wire 9 between the first electric wire 4 and the second motor generates high temperature. The high temperature instantly vaporizes the solid guanidine nitrate 10 wrapped around the outside of the resistance wire 9. Guanidine nitrate can generate a large amount of gas. At this time, the gas enters the interior of the airbag 11 through the connecting tube 8, and the airbag 11 is quickly inflated. The person who falls into the water can hold the airbag 11 to be rescued.

[0038] Furthermore, the life buoy body 1 is in a U-shaped shape, and thrusters 12 are fixedly mounted at both ends of the life buoy body 1.

[0039] Specifically: the lifebuoy body 1 can be moved by the propeller 12.

[0040] Furthermore, a signal receiver 13 and a GPS device 14 are fixedly installed at the bottom of the inner cavity of the lifebuoy body 1, and the signal receiver 13 and the GPS device 14 are located on the right side of the inner cavity of the lifebuoy body 1;

[0041] Specifically: by placing a signal receiver 13 and a GPS device 14 inside the lifebuoy body 1, the signal receiver 13 and the GPS device 14 can be connected to each other through a wired line or a wireless signal, and can also be connected to other devices that need to be connected in the device; in addition, it can also be connected to external monitoring equipment through a wired line or a wireless signal;

[0042] Since the internal equipment of the lifebuoy body 1 can quickly receive external signals, rescuers can accurately locate the current position of the lifebuoy body 1 through the GPS device 14.

[0043] Furthermore, handrails 15 are fixedly arranged on both the left and right sides of the top of the lifebuoy body 1, and the positions of the two handrails 15 are located above the airbag 11, and a deflation pipe is fixedly arranged on the rear side of the airbag 11;

[0044] Specifically, the handrail 15 is provided so that a person who falls into the water can grab the lifebuoy body 1, and the deflation pipe is provided so that the gas inside the airbag 11 can be released, so as to facilitate the next use.

[0045] Furthermore, an anti-collision pad 16 is fixedly installed at the head end of the lifebuoy body 1, and the anti-collision pad 16 is made of rubber;

[0046] Specifically, by providing the anti-collision pad 16 , the anti-collision pad 16 can be used to prevent the life buoy body 1 from being damaged by colliding with hard objects when moving, thereby improving the safety protection capability of the life buoy body 1 .

[0047] Furthermore, waterproof shells 17 are fixedly mounted on both the left and right sides of the lifebuoy body 1, and a plurality of light-emitting lamp bodies 18 are fixedly mounted on the tops of the two waterproof shells 17;

[0048] Specifically: by setting the luminous lamp body 18, it is convenient for rescue personnel to quickly find the position of the lifebuoy body 1 at night, and it is also convenient for people who fall into the water to quickly find the position of the lifebuoy body 1. The luminous lamp bodies 18 are arranged in series, and the luminous lamp bodies 18 can be turned on and off by the signal receiver 13.

[0049] The specific working principle is: the rescue personnel throw the lifebuoy body 1 into the water, and then remotely control the propeller 12 of the lifebuoy body 1 through the control device. When the lifebuoy body 1 moves to the vicinity of the person who falls into the water, the electric push rod 2 is then started, and the electric push rod 2 starts to drive the iron ball 7 on the surface of the push rod 6 to move through the opening to the surface of the second wire 5. At this time, the second wire 5 is connected, and the resistance wire 9 between the first wire 4 and the second motor generates high temperature. The high temperature instantly vaporizes the solid guanidine nitrate 10 wrapped outside the resistance wire 9. The guanidine nitrate can generate a large amount of gas. At this time, the gas enters the airbag 11 through the connecting pipe 8, and the airbag 11 is quickly inflated. The person who falls into the water can hold the airbag 11 to be rescued. By setting the anti-collision pad 16, the anti-collision pad 16 can be used to prevent the lifebuoy body 1 from being damaged by colliding with hard objects when moving, thereby improving the safety protection capability of the lifebuoy body 1.

[0050] Furthermore, in order to solve the existing problem that people who fall into the water have difficulty in breathing oxygen, blurred consciousness, and are prone to fainting, which leads to the inability to hold and grasp the lifebuoy, the device also includes:

[0051] An oxygen cylinder 19 is fixedly mounted at the bottom of the inner cavity of the lifebuoy body 1, a first oxygen supply pipe 20 is fixedly mounted at the left end of the oxygen cylinder 19, and a switch door 28 is movably hinged at the top of the lifebuoy body 1, and the switch door 28 is located directly above the oxygen cylinder 19;

[0052] Specifically: the staff opens the switch door 28 to replace the oxygen cylinder 19, and the first oxygen supply pipe 20 is a soft material pipe.

[0053] Further, a second oxygen supply pipe 21 is fixedly arranged on the top of the lifebuoy body 1, an oxygen mask 22 is fixedly arranged on the right end of the second oxygen supply pipe 21, a plurality of cable slots 32 are fixedly arranged on the top of the lifebuoy body 1, the second oxygen supply pipe 21 is inserted on the surface of the plurality of cable slots 32, an insert block 29 is fixedly installed at the bottom of the oxygen mask 22, a shell 30 is fixedly arranged on the top of the lifebuoy body 1, a spring latch 31 is inserted in the inner cavity of the shell 30, and the spring latch 31 is adapted to the insert block 29;

[0054] Specifically: by setting a plurality of cable slots 29, the second oxygen supply tube 21 can be inserted into the surface of the cable slots 29 to avoid shaking in water. The second oxygen supply tube 21 is a retractable soft material tube. By providing an insert block 29 at the bottom of the oxygen mask 22, when the oxygen mask 22 is not needed, the spring latch 31 can be pulled out and the insert block 29 can be inserted into the shell 30, and then the spring latch 31 can be released to fix it.

[0055] Furthermore, a gear 23 is rotatably connected to the bottom of the inner cavity of the lifebuoy body 1 , a connecting rod 24 is fixedly arranged on the front side of the surface of the push rod 6 , a rack 25 is fixedly installed on the front side of the connecting rod 24 , and the rack 25 is meshed with the gear 23 .

[0056] Furthermore, a valve 26 is fixedly installed on the top of the inner cavity of the lifebuoy body 1, the left end of the first oxygen supply pipe 20 is fixedly connected to the right end of the valve 26, the right end of the second oxygen supply pipe 21 is fixedly connected to the left end of the valve 26, and a butterfly valve 27 is fixedly installed on the top of the gear 23, and the butterfly valve 27 is rotatably connected to the inside of the valve 26.

[0057] The specific working principle is: when the emergency mechanism is activated, the push rod 6 moves and the connecting rod 24 drives the rack 25 to move. The movement of the rack 25 drives the gears 23 to rotate. When the gear 23 rotates, it drives the butterfly valve 27 inside the valve 26 to rotate. At this time, the valve 26 is in an open state. The oxygen inside the oxygen cylinder 19 can enter the oxygen mask 22 through the first oxygen supply pipe 20, the valve 26 and the second oxygen supply pipe 21. The person who falls into the water can wear the oxygen mask 22 in time to breathe oxygen.

[0058] The wiring diagram of the electric linear actuator, GPS device and signal receiver in the present invention is common knowledge in the art, and its working principle is a well-known technology. The model is selected according to the actual use. The GPS device model is M12, and the signal receiver model is CATVision-RD-CPU-RM. Therefore, the control method and wiring arrangement of the electric linear actuator, GPS device and signal receiver will not be explained in detail.

[0059] The invention aims to solve the problem that when the existing life buoy is remotely controlled to rescue a person who falls into the water, the person who falls into the water needs to grab the handle of the life buoy before the rescuer can remotely control the life buoy to return. However, the person who falls into the water does not have enough physical strength before the life buoy arrives, so it is difficult for the person who falls into the water to save physical strength and hold the life buoy tightly.
