[0018] Compared with the prior art, this lifesaving device has the following advantages:

[0019] 1. After the body absorbs wave energy, the water flow in the body becomes relatively calm, which plays a buffering role, reduces the impact of waves on the user, and improves the stability of the human body in the water. At the same time, due to the relative movement of the connecting belt and the body, the connecting belt drives the telescopic part to extend and retract into the body, the telescopic part drives the gear to rotate, and the gear drives the generator to generate electricity, that is, the wave energy is converted into electrical energy through the body, thereby realizing the self-power supply of the lifesaving device. In addition, the power generation structure is located between the body and the connecting belt, so the water resistance generated by the power generation structure is effectively reduced.

[0020] 2. When using this lifesaving device, after connecting the two ends of the connecting belt together, open the inflation mechanism, and the inflation mechanism inflates the airbag so that the airbag is inflated and closely attached to the waist of the human body, thereby improving the fixing effect of the connecting belt. At the same time, the volume of the inflated airbag increases on the one hand, which helps to increase the buoyancy; on the other hand, it increases the contact area between the human body and the water surface, and the water flow in the body is relatively calm, thereby significantly improving the user's stability in the water and reducing the chance of the user being overturned by waves.

[0021] 3. Being in water for a long time will cause hypothermia and weakness of hands. Hands are an important part of the body for escape while users are waiting for rescue. To prevent hands from becoming cold and weak, users press the crossbar to compress the reset spring and reduce the volume of the capsule, which then discharges air into the installation slot through the exhaust pipe. When the hand is released from the crossbar, the reset spring returns to its original state and the volume of the capsule increases and returns to its original state. At this time, the air in the installation slot flows into the capsule through the exhaust pipe. Since the battery and the lighting lamp generate heat when they are working, the heat heats the air in the installation slot. Therefore, through the above process, the heat generated by the lighting lamp when it is working can heat the handle in time, thereby providing heat to the hand, keeping the hand at a certain temperature and also keeping the hand at a certain degree of flexibility.

[0022] 4. The exhaust pipe exhausts and inhales air respectively through the exhaust check valve and the intake check valve. This structure effectively improves the fluidity of the air in the installation groove and makes full use of the heat generated by the lighting lamp.

[0023] 5. During the relative movement between the connecting belt and the body, the airbag is squeezed by the human body and the body and deformed. That is, one side of the airbag is squeezed, and the exhaust volume there is reduced; at the same time, the other side of the airbag is inflated and the volume increases. This structure further drives the connecting rod to extend and retract into the body through the connecting belt, further improving the power generation efficiency of the generator.

DETAILED DESCRIPTION

[0030] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0031] Reference Figures 1 to 5 A lifesaving device, comprising a U-shaped body 1, characterized in that it also comprises:

[0032] A connecting belt 2 is movably arranged on the inner side of the body 1; both ends of the connecting belt 2 are detachably connected;

[0033] A power mechanism, which is arranged on the body 1 and can drive the body 1 forward;

[0034] A generator 3 is arranged in the main body 1, and the output shaft of the generator 3 is connected to a gear 31 rotatably arranged in the main body 1 through a transmission mechanism; the transmission mechanism is a transmission gear 35, and the transmission gear 35 is coaxially fixed on the output shaft of the generator 3, and the transmission gear 35 is meshed and connected with the gear 31; a telescopic member is arranged between the gear 31 and the connecting belt 2, one end of the telescopic member extends out of the main body 1 and the end is hinged to the connecting belt 2, and the other end of the telescopic member extends into the main body 1 and is connected to the gear 31; when the telescopic member extends and retracts into the main body 1, the telescopic member can drive the gear 31 to rotate; the generator 3 is electrically connected to the power mechanism.

[0035] When the lifesaving device is used, the two ends of the connecting belt 2 are connected together so that the connecting belt 2 fits the waist of the human body. At this time, the human body is movably connected with the main body 1 through the connecting belt 2, and the human body floats on the water surface due to the buoyancy generated by the main body 1. The main body 1 is driven forward in the water by the power mechanism, assisting the human body to move in the water, and helping the user to escape danger.

[0036] When the main body 1 moves forward in the water, the waves impact the main body 1, causing the main body 1 to float up and down continuously. At this time, after the main body 1 absorbs the wave energy, the water flow in the main body 1 becomes relatively calm, which plays a buffering role, reduces the impact of the waves on the user, and improves the stability of the human body in the water. At the same time, due to the relative movement between the connecting belt 2 and the main body 1, the connecting belt 2 drives the telescopic part to extend and retract into the main body 1, the telescopic part drives the gear 31 to rotate, and the gear 31 drives the generator 3 to generate electricity, that is, the wave energy is converted into electrical energy through the main body 1, thereby realizing the self-power supply of the life-saving device. In addition, the power generation structure is located between the main body 1 and the connecting belt 2, so the water resistance generated by the power generation structure is effectively reduced.

[0037] Preferably, two second installation cavities 12 are provided on the main body 1, and a generator 3, a gear 31 and a telescopic member are installed in each of the second installation cavities 12; one end of each telescopic member extends into the second installation cavity 12, and the other end extends out of the main body 1; a cover is provided on the upper edge of the second installation cavity 12.

[0038] The provision of the second installation cavity 12 is helpful for installing and disassembling the generator 3, the gear 31 and the telescopic member.

[0039] Furthermore, a plurality of anti-slip ropes 14 are arranged on the outer edge of the main body 1 .

[0040] The provision of the anti-slip rope 14 helps to grasp the body 1 .

[0041] Specifically, an airbag 21 is disposed on the inner side of the connecting belt 2 , and the airbag 21 is connected to an inflation mechanism disposed on the body 1 , and the inflation mechanism can inflate the airbag 21 .

[0042] When using the lifesaving device, after connecting the two ends of the connecting belt 2 together, the inflation mechanism is turned on, and the inflation mechanism inflates the airbag 21, so that the airbag 21 is inflated and closely attached to the waist of the human body, thereby improving the fixing effect of the connecting belt 2. At the same time, the inflated airbag 21, on the one hand, becomes larger in volume, which helps to increase buoyancy; on the other hand, it increases the contact area between the human body and the water surface, and the water flow in the body 1 is relatively calm, thereby significantly improving the user's stability in the water and reducing the probability of the user being overturned by waves.

[0043] Specifically, a plurality of connection ropes 24 are arranged between the connection belt 2 and the inner side surface of the main body 1 ; one end of each of the connection ropes 24 is fixed on the connection belt 2 , and the other end is fixed on the main body 1 .

[0044] The provision of the connecting rope 24 ensures that the connecting belt 2 is always connected to the main body 1 and also allows sufficient movement space between the main body 1 and the connecting belt 2 .

[0045] Specifically, the power mechanism includes a battery 5 and two pump jet propellers 13 located on the body 1; each of the pump jet propellers 13 is disposed on a rear end of the body 1, each of the pump jet propellers 13 is electrically connected to the battery 5, and the battery 5 is electrically connected to the generator 3. Furthermore, a first installation cavity 11 is provided on the body 1, and the battery 5 is installed in the first installation cavity 11.

[0046] After the two pump-jet propellers 13 are started, the pump-jet propellers 13 suck in external water and eject it from the rear end of the main body 1, thereby driving the main body 1 to move forward in the water.

[0047] Specifically, a mounting groove 15 is provided at the front end of the main body 1, a refraction plate 151 is provided on the front edge of the mounting groove 15, and a lighting lamp 51 is provided in the mounting groove 15; the lighting lamp 51 is electrically connected to the battery 5, and a reflector 511 is provided in the mounting groove 15 around the periphery of the lighting lamp 51.

[0048] The arrangement of the illuminating lamp 51 and the refraction plate 151 helps the user to observe the surrounding environment when the light is weak, and also facilitates the rescuer to rescue the user. The illuminating lamp 51 reflects light through the reflector 511, further expanding the illumination range of the illuminating lamp 51.

[0049] Furthermore, a controller 52 is installed in the first installation cavity 11 , and the controller 52 is electrically connected to the lighting lamp 51 and the two pump jet propellers 13 through the battery 5 .

[0050] The user sends electrical signals to the lighting lamp 51 and the two pump jet propellers 13 respectively through the controller 52, thereby starting the lighting lamp 51 and the two pump jet propellers 13, thereby facilitating the user's operation.

[0051] Specifically, the telescopic member includes a rack 33, a connecting rod 34 and a rack mounting frame 36, the rack mounting frame 36 is fixed in the main body 1, the rack 33 is slidably set in the rack mounting frame 36, and the rack 33 is meshed and connected with the gear 31; one end of the connecting rod 34 extends out of the main body 1 and the end is hinged to the connecting belt 2 through the hinge 23, and the other end of the connecting rod 34 extends into the main body 1 and the end is rotatably set on the rack 33 through the pivot 341.

[0052] When the user uses the device, the airbag 21 is inflated and expands to fit closely against the waist of the human body. Due to the relative movement between the connecting belt 2 and the body 1, the connecting belt 2 drives the connecting rod 34 to extend and retract into the body 1. The connecting rod 34 drives the rack 33 to slide on the rack mounting bracket 36. The rack 33 drives the gear 31 to rotate, and the gear 31 drives the generator 3 to generate electricity through the transmission gear 35.

[0053] In addition, during the relative movement between the connecting belt 2 and the body 1, the airbag 21 is squeezed by the human body and the body 1 and deformed. That is, one side of the airbag 21 is squeezed, and the exhaust volume there is reduced; at the same time, the other side of the airbag 21 is inflated and the volume increases. This structure further drives the connecting rod 34 to extend and retract into the body 1 through the connecting belt 2, effectively improving the power generation efficiency of the generator 3. Specifically, two handles 6 are fixedly provided on the body 1; each of the handles 6 has a cavity 63, and a capsule 64 is provided in the cavity 63; the capsule 64 is connected to the mounting groove 15 via the exhaust pipe 62; each of the handles 6 is inserted with a T-shaped movable frame 65; one end of the vertical rod 651 of the movable frame 65 extends into the cavity 63 and the end is fixedly connected to the capsule 64, and the other end of the vertical rod 651 extends out of the handle 6 and the end is fixedly connected to the cross bar 652 of the movable frame 65; a return spring 66 is sleeved on the vertical rod 651; one end of the return spring 66 presses on the handle 6 and the other end presses on the cross bar 652.

[0054] Being in water for a long time will cause hypothermia and weakness of the hands. The hands are an important part of the user's body for escape while waiting for rescue. To prevent the hands from becoming cold and weak, the user presses the crossbar 652, compresses the reset spring 66, and reduces the volume of the capsule 64. The capsule 64 discharges air to the mounting groove 15 through the exhaust pipe 62. When the hand is released from the crossbar 652, the reset spring 66 recovers, and the volume of the capsule 64 increases and returns to its original state. At this time, the air in the mounting groove 15 flows into the capsule 64 through the exhaust pipe 62. Since a large amount of heat will be generated when the lighting lamp 51 is working, the heat heats the air in the mounting groove 15. Therefore, through the above process, the heat generated when the lighting lamp 51 is working can timely heat the handle 6, thereby providing heat for the hand, so that the hand can maintain a certain temperature, and at the same time, the hand can maintain a certain degree of flexibility.

[0055] Specifically, a three-way pipe 61 is provided on one end of the exhaust pipe 62 extending into the installation groove 15 ; an intake check valve 611 and an exhaust check valve 612 are respectively provided on two ports of the three-way pipe 61 .

[0056] The exhaust pipe 62 exhausts and inhales air respectively through the exhaust check valve 612 and the intake check valve 611. This structure effectively improves the fluidity of the air in the installation groove 15 and fully utilizes the heat generated by the lighting lamp 51 when it is working.

[0057] Specifically, the inflation mechanism includes an air bottle 4 installed on the body 1, and the air bottle 4 is connected to the air bag 21 via an air supply pipe.

[0058] The provision of the air bottle 4 helps to inflate the airbag 21 .

[0059] Furthermore, a solenoid valve 41 is provided on the output end of the air bottle 4 , and the solenoid valve 41 is electrically connected to the controller 52 through the battery 5 .

[0060] The electromagnetic valve 41 and the controller 52 facilitate the user to open and close the air bottle 4 .

[0061] Specifically, the end of the connecting rod 34 extending outside the main body 1 is connected to the support plate 22 via a hinge 23 , and the support plate 22 is fixed on the connecting belt 2 .

[0062] The support plate 22 prevents the connecting rod 34 from directly contacting the connecting belt 2 , thereby reducing the possibility of the connecting rod 34 piercing the connecting belt 2 .

[0063] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
