[0001] The invention belongs to the technical field of rescue, and in particular relates to a rapids emergency rescue device. Background Art

[0002] At present, the main way to rescue people who fall into the water is to throw lifebuoys, but there are many problems. Usually, lifebuoys can only be thrown near the person who falls into the water. If the person cannot swim, it is difficult to catch the lifebuoy even if the distance is close. Moreover, it is difficult to throw the lifebuoy near the person, which is even more difficult than the ring-tossing game. In flowing or rapid waters, the difficulty of rescue is further increased. Due to the complex water conditions and the difficulty of swimming, it is more difficult for the person who falls into the water to catch the lifebuoy, and the lifebuoy may move away with the water flow, resulting in a low rescue success rate.

[0003] Although there are new rescue equipment such as remote-controlled lifebuoys and drones that precisely deliver lifebuoys, they are expensive, require constant monitoring of battery power, and are greatly affected by rapid waters, so the effect of their use is not ideal.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figure 1-Figure 8 As shown:

[0028] A rapids emergency rescue device, comprising a rescue belt 5 and a weighting member 1 fixed to the head of the rescue belt 5, wherein a plurality of floating clamps 6 are fixedly connected to both sides of the rescue belt 5, a control rope 7 is slidably connected to the inner side of the floating clamps 6, a plurality of fixing sleeves 8 are fixedly connected to the outer sides of the corresponding positions of the two control ropes 7, a flexible connecting piece 9 is fixedly connected to the outer sides of both ends of the fixing sleeve 8, and two flexible connecting pieces 9 located on both sides of the rescue belt 5 and in the same direction are fixedly connected to a control board 10 together, and the control board 10 can be tilted relative to the rescue belt 5;

[0029] The rescue belt 5 and the control rope 7 are stored as a whole, and the rescue belt 5 is unfolded in the water for rescue.

[0030] In this embodiment: At present, the method of throwing a life buoy is mainly used to rescue people who fall into the water, but there are many problems. Usually, the life buoy can only be thrown near the person who falls into the water. If the person who falls into the water cannot swim, it is difficult to catch it even if the distance is close. Moreover, it is difficult to throw the life buoy near the person, which is even more difficult than the difficulty of the ring-tossing game. In flowing or rapid waters, the difficulty of rescue is further increased. Due to the complex water conditions and the difficulty of swimming, it is more difficult for the person who falls into the water to catch the life buoy, and the life buoy may be moved away by the water flow, resulting in a low rescue success rate.

[0031] Although there are new rescue equipment such as remote-controlled life buoys and drones that accurately deliver life buoys, they are expensive, require constant attention to battery power, and are greatly affected by rapid waters, making their use less effective.

[0032] In this solution, the rescue method is improved, the rescue area and the rescue success rate are increased, and multiple people can be rescued in water at the same time, and the rescue effect is still good for flowing or rapid waters, which reduces the rescue difficulty, equipment cost and maintenance cost, and does not require charging, and has a wide range of use;

[0033] The following is an explanation of rescue in non-flowing waters:

[0034] When a person falls into the water in a non-flowing water area, the rescue belt 5 is unfolded into a belt shape in the water. Since a floating card 6 is fixed on the outside of the rescue belt 5, the rescue belt 5 can float on the water surface whether it is inflated or not. When the rescue belt 5 is not in use, it can be stored, for example, by rolling it up, rolling it up through a winding device, or folding it. When it needs to be unfolded in the water, the head of the rescue belt 5 has a weighted piece 1, which is heavy and can be thrown to the rescuer. The belt 5 is unfolded on the water surface, and finally the rescue belt 5 floats on the water surface. When throwing the supporting rod, there is no need to throw the weighted piece 1 near the person who falls into the water. Firstly, it is difficult to throw the weighted piece 1 near the person who falls into the water, and it may not be thrown accurately. Secondly, throwing the weighted piece 1 near the person who falls into the water may hit the person who falls into the water, making the situation of the person who falls into the water more dangerous. The weighted piece 1 only needs to be farther away from the shore relative to the person who falls into the water. The weighted piece 1 is thrown and carried in the water. The state of the rescue belt 5 is as follows: Figure 7 As shown in FIG. 1 , if the drowning person can swim to the rescue belt 5 and grab the rescue belt 5, the people on the shore can pull the rescue belt 5 to pull the drowning person to the shore. If the drowning person is difficult to move in the water, the angle of the control board 10 can be changed by pulling the control rope 7, as shown in FIG. Figure 3 As shown in the figure, the control board 10 is tilted relative to the rescue belt 5. When the control board 10 changes its angle, the rescue belt 5 will be pulled, causing the rescue belt 5 to tilt while being pulled. Because when the control board 10 moves in the water, the pulling force will generate a component force along the direction of the control board 10 and a component force perpendicular to the board direction. The component force along the direction of the control board 10 will cause the control board 10 to have a tendency to move along the plane direction of the control board 10. If other forces such as water resistance cannot completely balance this component force, the board will move obliquely, so that the rescue belt 5 will be tilted. Figure 3 The tilt angle of the control panel 10 shown is such that when the rescue belt 5 is pulled, the rescue belt 5 will move to the left. When the tilt angle of the control panel 10 is controlled, the rescue belt 5 needs to be moved toward the person who falls into the water, so that the person who falls into the water can grab the rescue belt 5 and be rescued.

[0035] The following is an explanation of rescue in moving waters:

[0036] When a person falls into a flowing water, he or she will float with the current. If the person cannot swim, it is difficult for the person to catch the life buoy by the traditional method of throwing a life buoy. The ring-tossing game itself is not easy, and it will be even more difficult if the ring-tossing game is about a moving target. Even if the life buoy is thrown near the person so that the person can catch it, for a person who cannot swim, it can only prevent him or her from drowning temporarily, and the person will continue to drift with the water and find it difficult to get ashore. Figure 7 For example, assuming that the water flow is from left to right at this time, when the weighted member 1 is thrown to unfold the rescue belt 5 in the water, the rescue belt 5 should be placed in front of the person in the direction of the water flow and across the water flow path to stop the person drifting downstream, that is, Figure 7 On the right side of the person in the middle, the flowing water will cause the rescue belt 5 to move with the water as well, so it is also necessary to change the direction of the control board 10, and to choose whether to apply a pulling force toward the shore according to the water flow conditions, so as to better maintain the relative stability of the rescue belt 5 and prevent the rescue belt 5 from twisting like a twist, so that the rescue belt 5 can stay in a relatively fixed position in the water relative to the shore. This principle is the same as the principle of flying a kite, and no mechanical analysis is required.

[0037] By fixing the limiting head 11 on the head of the control rope 7 , the control rope 7 at the front section can be prevented from being separated from the floating clamp 6 .

[0038] In an optional embodiment, the rescue belt 5 is a flexible tubular inflatable structure, and also includes a weight piece 1 for closing the head of the rescue belt 5, the weight piece 1 is made of magnetic material, the inner sides of the two weight pieces 1 are slidably connected with a support plate 101, the inner side of the support plate 101 is slidably connected with a trigger rod 102, both ends of the trigger rod 102 are fixedly connected with a float 106, the inner side of the support plate 101 is slidably connected with a clamping strip 104 perpendicular to the trigger rod 102, the inner side of the trigger rod 102 is provided with a receiving groove 103, the inner side of the weight piece 1 is provided with a clamping slot 105, and the clamping strip 104 can move between the clamping slot 105 and the receiving groove 103.

[0039] In this embodiment: in order to prevent the rescue belt 5 from twisting like a twist in the water, and to prevent the rescue belt 5 from twisting when the weighted member 1 drives the rescue belt 5 to fly in the air, and to reduce the air resistance caused by the control panel 10 following the rescue belt 5, at the same time, the rescue belt 5 in the water can be filled with gas, so that the drowning person will not sink when grabbing the rescue belt 5. This embodiment can solve the above technical problems. The floating card 6 itself has a certain buoyancy, but the buoyancy of the floating card 6 is limited to preventing the rescue belt 5 from sinking, and cannot provide buoyancy for the drowning person. In order to obtain a better rescue effect, it is necessary to fill the rescue belt 5 in the water with gas, and the card strip 104 is a rigid material with magnetic response;

[0040] Before throwing the weighted piece 1, it is necessary to separate and temporarily fix the two weighted pieces 1, and move the two weighted pieces 1 in opposite directions by hand pulling. Since the weighted piece 1 is made of magnetic material, and the clamping strip 104 is a magnetically responsive rigid material, when the weighted piece 1 moves along the support plate 101, when the clamping strip 104 corresponds to the position of the clamping slot 105, under the influence of the magnetic force, the clamping strip 104 will immediately enter the clamping slot 105, and a "click" sound can be heard, which is convenient for judging whether the clamping strip 104 is in place with the clamping slot 105. When all the clamping strips 104 and the clamping slots 105 are in place, the position of the trigger rod 102 can be adjusted to prevent the accommodating groove 103 on the trigger rod 102 from corresponding to the position of the clamping strip 104. The outer surface of the trigger rod 102 can resist the clamping strip 104 to prevent the clamping strip 104 from moving, so that the clamping strip 104 and the clamping slot 105 are firmly matched, so that the cooperation between the clamping strip 104 and the clamping slot 105 limits the position of the two weighted pieces 1.

[0041] The sliding resistance of the trigger rod 102 on the inner side of the support plate 101 is greater than the resistance caused by the unexpected force, and less than the buoyancy provided by the float 106 when the weighted member 1 falls into the water; the movement of the trigger rod 102 on the inner side of the support plate 101 should have a certain resistance to prevent the trigger rod 102 from moving randomly relative to the support plate 101, but the resistance to movement between the trigger rod 102 and the support plate 101 cannot be greater than the buoyancy provided by the float 106 when the weighted member 1 falls into the water;

[0042] When throwing the weighting member 1, since the two weighting members 1 are in a non-contacting state at this time, the head of the rescue belt 5 can be stretched open, so that the head of the rescue belt 5 can enter the air. When the weighting member 1 flies together with the rescue belt 5, air will enter the inner side of the rescue belt 5, so that a certain amount of air is filled into the rescue belt 5. At this time, the rescue belt 5 is in a slightly expanded state. Affected by the air injection, the rescue belt 5 in flight is not easy to be twisted. When the rescue belt 5 is not twisted, the control ropes 7 on both sides of the rescue belt 5 will not cross. However, since the head of the rescue belt 5 is in an unclosed opening state, the gas pressure inside the rescue belt 5 is slightly greater than the external atmospheric pressure. Therefore, when the control panel 10 is affected by wind resistance, the control panel 10 will tilt (such as Figure 2 As shown), reducing the resistance between the control panel 10 and the air;

[0043] When the weighted member 1 falls into the water, the buoyancy generated by the float 106 drives the trigger rod 102 to move relative to the support plate 101. No matter which direction the trigger rod 102 moves, the trigger rod 102 will make the receiving groove 103 correspond to the position of the card strip 104 (such as Figure 5 As shown), the magnetic force between the weight pieces 1 will cause the two weight pieces 1 to move toward each other until the two weight pieces 1 squeeze the head of the rescue belt 5 closed (as shown). Figure 6 As shown in the figure, the head of the rescue belt 5 is sealed to form a closed space. When the rescue belt 5 is wound by the winding device, the rescue belt 5 is squeezed when it is wound on the winding device, so that the gas pressure inside the rescue belt 5 increases. At this time, the rescue belt 5 in the water is in a relatively hard state. The rescue belt 5 becomes hard under the influence of the gas pressure and can support the control board 10, so that the upper and lower control boards 10 are more inclined to be in the same plane (as shown in the figure). Figure 1 It should be noted that after the rescue belt 5 falls into the water and before it is rolled up, the angle of the control board 10 should be adjusted by the control rope 7. At this time, the angle adjustment of the control board 10 is more convenient.

[0044] In an optional embodiment, a pressure valve 12 is fixedly installed on the inner side of one end of the rescue belt 5 close to the weight member 1 .

[0045] In this embodiment: the pressure valve 12 can be an air pressure safety valve, an air pressure opening valve or an air pressure trigger valve; the valve is mainly used to release gas under a specific pressure, and relies on the air pressure to reach a specific value to start the exhaust function; as the rescue belt 5 is continuously reeled in, the gas pressure inside the rescue belt 5 continues to increase, and the gas inside the rescue belt 5 needs to be discharged through the pressure valve 12 to prevent the rescue belt 5 from rupturing.

[0046] In an optional embodiment, a connecting rod 2 is fixedly connected to the outer side of one end of the weight member 1, a counterweight ball 3 is fixedly connected to the top of the connecting rod 2, a round rod 4 is fixedly connected to the outer side of one end of the connecting rod 2, and a through hole 41 is opened at one end of the round rod 4.

[0047] In this embodiment: if the person who falls into the water is far away from the shore, it is difficult to throw the fish a long distance by hand throwing. The fish can be thrown by throwing a lead sinker with a sea fishing rod. The distance for ordinary people to throw a lead sinker is about 30-80 meters. Experienced people can throw it farther, such as Figure 8 As shown, a guide ring is provided at the top end of the hand rod, one end of the line passes through the through hole 41 and is fixed on the round rod 4, so that after the line passes through the guide ring, the other end of the line is located at the tail of the hand rod. By holding the hand rod and the line at the same time, after swinging the hand rod to a suitable angle, release the other end of the line, so that the round rod 4 flies out with the line. This method is the same as the method of throwing the lead sinker with a sea rod.

[0048] In an optional embodiment, a thread is provided on the outer side of the end of the round rod 4, and the end of the round rod 4 is connected to an extension rod 42 through the thread.

[0049] In this embodiment, the harpoon gun can also be used for ejection. The extension rod 42 is threadedly connected to the round rod 4, and the extension rod 42 is inserted into the harpoon gun for ejection.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
