Description

Technical Field

[0001] The present invention relates to the technical field of ice surface rescue, and particularly to an automatic inflatable ice surface rescue equipment and a rescue method thereof. Background Art

[0002] In winter, especially in the north of China, most water areas such as rivers and lakes will basically freeze. However, due to the uneven thickness of the ice layer, accidents of accidentally falling into frozen waters often occur, and ordinary rescue equipment is often not suitable for ice surface rescue. In addition, because the drowning victims in winter are basically wearing thick clothes, it further increases the rescue difficulty. Moreover, because the hardness of the ice surface is often unknown, rescue personnel need to approach the drowning victim carefully, and their own safety cannot be fully guaranteed.

[0003] Nowadays, most rescue equipment is still relatively primitive, such as fishing rods, lifebuoys, inflatable boats, etc. Firstly, due to their product characteristics, they cannot be used on the ice surface. Secondly, due to the limitations of the ice surface, they cannot be applied to most scenarios. Thirdly, rescue personnel need to get extremely close to the rescued person, and the safety of rescue personnel cannot be guaranteed, which may lead to secondary accidents. Therefore, we propose an automatic inflatable ice surface rescue device and a rescue method thereof. Summary of the Invention

[0004] An automatic inflatable ice surface rescue equipment and a rescue method thereof proposed by the present invention solve the problems of poor rescue effect and low rescue safety factor of existing ice surface rescue equipment.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An automatic inflatable ice surface rescue equipment includes an ice surface rescue remote control vehicle and an inflatable rescue airbag. A rope is connected to the tail end of the ice surface rescue remote control vehicle, and a locking and releasing mechanism is installed at the front end of the ice surface rescue remote control vehicle. An inflatable rescue airbag in a wound state is fixed on the locking and releasing mechanism through a connecting rope. An air pump is also installed on the ice surface rescue remote control vehicle, and the output end of the air pump is connected to the inflatable rescue airbag through a conduit.

[0007] Preferably, the locking and releasing mechanism includes a fixed bracket. A bushing is installed through the opening at the horizontal section of the top of the fixed bracket. A solenoid valve is installed on one side wall of the fixed bracket, and the output end of the solenoid valve is connected to a telescopic shaft passing through the bushing.

[0008] Preferably, a plurality of uniformly distributed horizontal handles are installed on the front surface of the inflatable rescue airbag.

[0009] Preferably, a plurality of water guiding channels penetrating the inflatable rescue airbag are provided on the inflatable rescue airbag.

[0010] Preferably, a weight is filled at the tail end of the inflatable rescue airbag.

[0011] Further, after the inflatable rescue airbag is deployed, it is in an arc structure. The front length R1 and the bottom length R2 of the inflatable rescue airbag are inconsistent, and the parameter is 0.5 < R1 / R2 < 0.99.

[0012] Furthermore, the length of the inflatable rescue airbag is between 1.3 m and 3 m, and the width of the inflatable rescue airbag is between 0.6 m and 1.2 m.

[0013] Preferably, one or two sliders for reducing friction are installed at the tail of the ice surface rescue remote control vehicle.

[0014] The rescue method of the above-mentioned automatic inflatable ice surface rescue device includes the following steps:

[0015] S1: The rescuer places the ice surface rescue remote control vehicle on the ice surface near the drowning person.

[0016] S2: The rescuer remotely controls the ice surface rescue remote control vehicle to drive on the ice surface until it is close to the ice surface at the position of the drowning person.

[0017] S3: The rescuer remotely controls the locking and releasing mechanism to loosen the connection rope wound around the inflatable rescue airbag.

[0018] S4: The inflatable rescue airbag unfolds and falls into the water under the gravity of the weight at the tail end, and then the air pump automatically inflates the inflatable rescue airbag.

[0019] S5: When the inflatable rescue airbag is inflated, it gradually forms a "banana-like" shape, semi-wraps the drowning person, and uses the buoyancy generated by the airbag to float the drowning person to the water surface.

[0020] S6: The rescuer pulls the ice surface rescue remote control vehicle to move on the ice surface through the rope. At the same time, the ice surface rescue remote control vehicle drives the inflatable rescue airbag to pull the drowning person from the ice hole water surface to the ice surface until the shore to complete the rescue.

[0021] Preferably, in step S4, when the inflatable rescue airbag falls into the water, under the action of gravity, it falls from the edge of the ice surface to one side of the drowning person, facilitating the drowning person to grab the inflatable rescue airbag through the handle.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] The present invention provides an automatic inflatable ice surface rescue device. When a person falls into the water on the ice surface, the inflatable rescue airbag can be quickly transported to the vicinity of the falling position through the ice surface rescue remote control vehicle, without the need for rescuers to approach manually, and the safety performance of the rescuers is high;

[0024] Moreover, with the setting of the inflatable rescue airbag, the drowning person can be easily lifted from underwater to the water surface, flush with the ice surface. Then, by dragging the ice surface rescue remote control vehicle and the inflatable rescue airbag with a rope, the drowning person can be quickly pulled out of the ice cave. It is safe, reliable, easy to operate, reduces the rescue difficulty, and has strong practicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] 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.

[0032] Refer to Figures 1-5 , an automatic inflatable ice surface rescue device, including an ice surface rescue remote control vehicle 1 and an inflatable rescue airbag 4. A rope 5 is connected to the tail end of the ice surface rescue remote control vehicle 1. A locking and releasing mechanism 2 is installed at the front end of the ice surface rescue remote control vehicle 1. An inflatable rescue airbag 4 in a wound state is fixed on the locking and releasing mechanism 2 through a connecting rope. An inflation pump 3 is also installed on the ice surface rescue remote control vehicle 1. The output end of the inflation pump 3 is connected to the inflatable rescue airbag 4 through a conduit.

[0033] The locking and releasing mechanism 2 includes a fixed bracket 7. A shaft sleeve 9 is installed through the opening at the top horizontal section of the fixed bracket 7. An electromagnetic valve 10 is installed on one side wall of the fixed bracket 7, and the output end of the electromagnetic valve 10 is connected to a telescopic shaft 8 that penetrates through the shaft sleeve 9.

[0034] A plurality of uniformly distributed horizontal handles 6 are installed on the front of the inflatable rescue airbag 4, facilitating the drowning person to grasp the handles 6 for climbing and fixing.

[0035] A plurality of water guiding channels (not shown in the figure) that penetrate through the inflatable rescue airbag 4 are provided on the inflatable rescue airbag 4. After falling into the water, the water flows through the water guiding channels, reducing the impact of the water flow on the inflatable rescue airbag 4.

[0036] A weight 11 is filled at the tail end of the inflatable rescue airbag 4. After the inflatable rescue airbag 4 is deployed, under the action of the gravity of the weight 11, the tail end of the inflatable rescue airbag 4 can quickly enter the water.

[0037] After the inflatable rescue airbag 4 is deployed, it is in an arc structure. The arc structure design not only facilitates towing and is not easily blocked at both ends during towing, but also is more convenient for winding. The front length R1 and the bottom length R2 of the inflatable rescue airbag 4 are inconsistent, and the parameter is 0.5 < R1 / R2 < 0.99. The length of the inflatable rescue airbag 4 is between 1.3 m and 3 m, and the width of the inflatable rescue airbag 4 is between 0.6 m and 1.2 m.

[0038] One or two sliders for reducing friction are installed at the tail of the ice surface rescue remote control vehicle 1. When rescuing on the ice surface, the contact area with the ice surface is increased to reduce excessive local pressure.

[0039] The rescue method of the above-mentioned automatic inflatable ice surface rescue device includes the following steps:

[0040] S1: The rescuer places the ice surface rescue remote control vehicle 1 on the ice surface near the drowning person.

[0041] S2: The rescuer remotely controls the ice surface rescue remote control vehicle 1 to drive on the ice surface until it is close to the ice surface where the drowning person is located.

[0042] S3: The rescuer remotely controls the locking and releasing mechanism 2 to loosen the inflatable rescue airbag 4 wound by the connecting rope. When the equipment is not in use, the electromagnetic valve 10 is not energized, and the connecting rope tightly sleeves on the telescopic shaft 8 to ensure that the inflatable rescue airbag 4 is in a stored state. When the equipment is in use, the electromagnetic valve 10 is energized, pulling the telescopic shaft 8 to make a contraction movement in the shaft sleeve 9, and the connecting rope disengages from the telescopic shaft 8, making the inflatable rescue airbag 4 in an unfolded state.

[0043] S4: The inflatable rescue airbag 4 unfolds and falls into the water under the gravity of the end weight 11, and then the air pump 3 automatically inflates the inflatable rescue airbag 4.

[0044] S5: When the inflatable rescue airbag 4 is inflated, it gradually forms a "banana-like" shape, semi-wraps the drowning person, and uses the buoyancy generated by the airbag to float the drowning person to the water surface.

[0045] S6: The rescue personnel pull the ice surface rescue remote control vehicle 1 on the ice surface through the rope 5. At the same time, the ice surface rescue remote control vehicle 1 drives the inflatable rescue airbag 4 to pull the drowning person from the ice cave water surface to the ice surface until the shore to complete the rescue.

[0046] In the above step S4, when the inflatable rescue airbag 4 falls into the water, under the action of gravity, it falls from the edge of the ice surface to one side of the drowning person, facilitating the drowning person to grab the inflatable rescue airbag 4 through the handle 6.

[0047] As described above, it is only the 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, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
