Description

Technical Field

[0001] The present invention relates to the technical field of fire fighting and rescue, and particularly relates to a water rescue device for fire fighting and rescue. Background Art

[0002] The water rescue devices for fire fighting and rescue are the general names of various tools and equipment used for rescue work on the water surface.

[0003] Existing such devices have problems in terms of unsafe use. For example, a water rescue device disclosed in Chinese Patent Publication No. "CN108622335B". When using this device, the rescuer needs to carry the device to the area near the drowning person's falling water area. However, this device includes components such as a propulsion motor and a propeller, and these components are relatively heavy. During the process of the rescuer carrying the device to the water area, it will consume a large amount of the rescuer's physical strength, and then make the carrier of the device unable to swim, thus causing a safety hazard of drowning. Accordingly, the present application proposes a water rescue device for fire fighting and rescue. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose a water rescue device for fire fighting and rescue.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions: A water rescue device for fire fighting and rescue includes a buoyancy mechanism and a support mechanism. The buoyancy mechanism includes an air pipe, an airbag, a rising wing, and a limiting ring. The buoyancy mechanism is used to provide buoyancy for the fallen water personnel. The limiting ring is fixedly connected to the rising wing, and the air pipe is fixedly connected to the airbag; The support mechanism includes a limiting rod, a support plate, a spring box, and a limiting clip. The support mechanism is used to support the head of the fallen water personnel. The limiting rod is fixedly connected to the spring box, and the limiting clip is fixedly connected to the limiting rod.

[0006] Preferably, a steel wire rope is fixedly connected to the limiting ring, and the end of the steel wire rope away from the limiting ring is height-connected to a winding wheel. A winding motor is arranged at the center of the winding wheel, and the lower surface of the winding motor is fixedly connected to a mounting plate.

[0007] Preferably, the rising wing is divided into two parts, and the two parts of the rising wing are rotatably connected. A first torsion spring is arranged between the two parts of the rising wing.

[0008] Preferably, a protective shell is arranged below the limiting ring, a propeller is arranged inside the protective shell, a spring rod is fixedly connected to the side wall at the connection of the two parts of the rising wing, and a clamping block is slidably connected to the spring rod.

[0009] Preferably, the number of the support plates is two, and the two support plates are fixedly connected to each other. A guide rod is fixedly connected inside the spring box, and the guide rod is slidably connected to the support plate.

[0010] Preferably, the support plate is slidably connected to the limiting rod. A second torsion spring is arranged at the lower end of the limiting rod, and a trigger rod is arranged at one end of the limiting rod away from the protective shell.

[0011] Preferably, a tension spring is fixedly connected inside the spring box. The tension spring is fixedly connected to one of the support plates. A connecting rod is fixedly connected between the support plates, and a semi-circular pin is fixedly connected to one of the support plates.

[0012] The present invention has the following beneficial effects: 1. By providing the rising wing, when the device moves towards the drowning person, it can dive to a certain depth, thus avoiding the situation where the swinging of the drowning person's arm affects the rescue. At the same time, when pulling the drowning person towards the shore, the rising wing will unfold to provide additional lift for the drowning person, so that the upper body of the drowning person is always above the water surface.

[0013] 2. By providing the support plate, when the drowning person is unconscious, the device can pop out to support the head of the drowning person, thus preventing the head of the drowning person from falling into the water during the rescue and avoiding the phenomenon of drowning during the rescue. During use, if the drowning person is trapped in the device, it will drive the limiting rod to rotate and release the limit on the support plate, and then the tension spring will pull out the support plate to support the head of the drowning person.

[0014] 3. By providing the propeller and the steel wire rope, when the device is in use, the propeller can make the device contact the drowning person and rescue him without the need for rescuers to enter the water to rescue the drowning person. This avoids the problem of physical exhaustion of rescuers caused by carrying equipment when using the device, and further avoids the potential safety hazards caused by the physical exhaustion of rescuers and the problem of insecurity during use.

[0015] 4. By providing the winding motor, during the use of the device, the winding motor can rotate to drive the winding wheel to rotate and wind the steel wire rope. This process also does not require rescuers to enter the water to participate, which allows rescuers to operate the device in a safer place. Since rescuers do not need to enter the water to use the device, it can effectively protect rescuers. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Embodiment 1:

[0019] Refer to Figure 1-4 , a water rescue device for fire fighting and rescue, including a buoyancy mechanism and a support mechanism. The buoyancy mechanism includes an air pipe 5, an airbag 16, a rising wing 6, and a limit ring 11. The buoyancy mechanism is used to provide buoyancy for the drowning person. The rising wing 6 is divided into two parts. The two parts of the rising wing 6 are rotatably connected, and a first torsion spring 7 is arranged between the two parts of the rising wing 6.

[0020] A spring rod 23 is fixedly connected to the side wall at the connection of the two parts of the rising wing 6, and a clamping block 22 is slidably connected to the spring rod 23.

[0021] The limiting ring 11 is fixedly connected to the rising wing 6, the air pipe 5 is fixedly connected to the airbag 16, a protective shell 10 is arranged below the limiting ring 11, and a propeller 15 is arranged inside the protective shell 10.

[0022] A steel wire rope 4 is fixedly connected to the limiting ring 11, one end of the steel wire rope 4 away from the limiting ring 11 is connected to a winding wheel 2 at a certain height, a winding motor 3 is arranged at the center of the winding wheel 2, and the lower surface of the winding motor 3 is fixedly connected to a mounting plate 1.

[0023] In this embodiment, the outer shape structure of the rising wing 6 is similar to that of an airplane wing. This shape can provide a certain upward lift force in water. When the state of the rising wing 6 is as Figure 3 shown, at this time, the larger part of the area of the rising wing 6 is located above, and the smaller part is located below. When the device moves towards the drowning person, the rising wing 6 will provide a downward pressure for the device. This is because the larger part of the area of the rising wing 6 is reversed, that is, the direction of the original lift force is reversed. Therefore, the larger part of the area of the rising wing 6 will provide a downward force for the device when it is not unfolded, so that the device can dive to a certain depth when moving towards the drowning person.

[0024] Furthermore, the two limiting rods 9 are rotatably connected to the limiting ring 11, and there is a second torsion spring 12 for resetting at the rotational connection. And the two limiting rods 9 can only rotate in the direction as Figure 3 shown. This is because the trigger rod 17 is fixedly connected to one limiting rod 9 and extends into the other limiting rod 9, and there is a blocking part on the outer side of the other limiting rod 9. So when the limiting rod 9 of the device hits the drowning person, the limiting rod 9 can rotate a certain angle towards the inside of the device and frame the drowning person between the limiting ring 11 and the limiting rod 9.

[0025] Furthermore, when the position of the limiting rod 9 is as Figure 3 shown, the limiting clip 14 will disengage from the rising wing 6, so that the rising wing 6 will be fully unfolded under the action of the first torsion spring 7. And there is a protruding part on the rising wing 6. Under the action of the first torsion spring 7, this protruding part will be stuck between the two clamping blocks 22. During this period, the clamping blocks 22 will be pushed apart. After the protruding part is completely stuck between the clamping blocks 22, under the action of the spring rod 23, the two parts of the rising wing 6 will unfold like Figure 3 shown and lock the two parts.

[0026] Furthermore, the propeller 15 is a prior art. Its rear end is connected to a motor and a battery, which are also prior arts. The battery can make the motor rotate, and the rotation of the motor can drive the propeller 15 to rotate and push the device to move. Embodiment 2:

[0027] Different from the first embodiment, this embodiment also has the following further content: There are two support plates 8, which are fixedly connected between the two support plates 8. A guide rod 19 is fixedly connected in the spring box 13. The guide rod 19 is slidably connected with the support plate 8. The support plate 8 is slidably connected with the limit rod 9. The limit clip 14 is fixedly connected with the limit rod 9. A second torsion spring 12 is arranged at the lower end of the limit rod 9. One end of one limit rod 9 away from the protective shell 10 is provided with a trigger rod 17.

[0028] In this embodiment, the air pipe 5 is connected to the airbag 16, and the air pipe 5 needs to be connected to an external air source. The mounting plate 1 needs to be fixed on the shore. When the device frames the drowning person between the limit ring 11 and the limit rod 9, the air source can be turned on to allow gas to enter the airbag 16, so that the airbag 16 can expand and provide buoyancy for the device.

[0029] Further, the device needs to approach the drowning person from the back direction of the drowning person. When the device frames the drowning person between the limit ring 11 and the limit rod 9, the lifting wing 6 will unfold. At this time, the outer shape structure of the lifting wing 6 is similar to that of an airplane wing. Then, the winding motor 3 is started, and the winding motor 3 will wind the steel wire rope 4 onto the winding wheel 2 and pull the drowning person towards the shore. Embodiment Three:

[0030] The support mechanism includes a limit rod 9, a support plate 8, a spring box 13, and a limit clip 14. The support mechanism is used to support the head of the drowning person. The limit rod 9 is fixedly connected with the spring box 13.

[0031] In this embodiment, the connecting rod 20 has two parts, which are in contact with each other by an inclined surface. One of the two parts is connected to the support plate 8, and the other is connected to the semi-circular pin 21. When the drowning person is framed between the limit ring 11 and the limit rod 9, the limit rod 9 will rotate towards the inside of the device. When the limit rod 9 rotates towards the inside of the device, it will drive the trigger rod 17 to rotate backward. The part of the trigger rod 17 in contact with the semi-circular pin 21 is semi-circular. When the trigger rod 17 rotates backward, the limit on the semi-circular pin 21 will be released.

[0032] Further, when the limit is released, the support plate 8 can pop out from the limit rod 9. During this process, due to the release of the limit, under the action of the tension spring 18, the support plate 8 will pop out from the limit rod 9. After popping out, it can provide support for the head of the drowning person to prevent their head from entering the water again.

[0033] Further, when the device pulls the drowning person towards the shore, if the drowning person is in a coma, then the head of the drowning person will fall backward due to inertia. During this period, the head of the drowning person will be blocked by the support plate 8, thereby providing support for the head of the drowning person to prevent their head from entering the water.

[0034] As described above, it is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
