Description

Technical Field

[0001] The utility model relates to the field of water rescue equipment, in particular to a multifunctional rescue water ski. Background Art

[0002] As a high-tech auxiliary tool designed specifically for water rescue, the rescue water ski significantly improves rescue efficiency and safety, especially in open, complex, or fast-flowing water environments. Combining buoyancy materials, a power system, and intelligent control technology, this device enables rescuers to approach drowning victims with greater speed and precision, enabling them to execute rescue operations. The rescue water ski not only provides rescuers with a stable platform for on-water mobility but also enables flexible control of speed and direction through an integrated control system, making it an indispensable piece of equipment for modern water rescue operations.

[0003] The most common water ski rescue method currently on the market relies mainly on manual operation by the rescuer. In this process, the rescuer will first put a lifebuoy on themselves or hold it in their hands. Using the water ski's power device (usually driven by a motor) and a handheld controller, they control the water ski's movement path on the water surface and quickly approach the person who has fallen into the water. Once close, the rescuer needs to throw the lifebuoy to the person who has fallen into the water and instruct them to wear it correctly. Afterwards, the person who has fallen into the water needs to grab the edge of the water ski and be towed by the rescuer to return to the shore together.

[0004] However, the existing rescue process has significant shortcomings. First, the accuracy of throwing the lifebuoy is difficult to guarantee, which may result in multiple attempts to successfully pass it. Second, in a state of panic, the drowning person may swing his hands uncontrollably due to nervousness, making it difficult to quickly and stably grab the lifebuoy, which not only prolongs the rescue time but also increases the safety risk of the drowning person. Finally, even if the drowning person successfully puts on the lifebuoy, due to the inconvenience of the operation, the rescuers still need to stop and perform additional operations to ensure that the drowning person can safely grab the water ski. This process is not only time-consuming, but may also cause new safety hazards due to the distraction of the rescuers. Utility Model Content

[0005] In order to overcome the shortcomings that a life buoy needs to be carried manually and has poor throwing accuracy, the utility model provides a multifunctional rescue water ski for dropping a life buoy at a fixed point.

[0006] A multifunctional rescue water ski comprises a water ski, a servo motor, a screw rod, a guide rod, a push plate, a life buoy and an opening and closing assembly. The water ski is equipped with a power assembly and a controller for driving the water ski. A placement cavity is opened in the water ski, and the placement cavity is installed with the servo motor. One end of the screw rod is connected to the output shaft of the servo motor, and the other end is rotatably connected to the water ski. The guide rod is connected to the water ski. One end of the push plate is threadedly connected to the screw rod, and the other end is slidably connected to the guide rod. A life buoy is placed in the water ski. The servo motor is connected to the controller by wire. An opening and closing assembly is provided at the opening of the placement cavity to prevent the life buoy from sliding out of the water ski.

[0007] Preferably, the opening and closing assembly includes a baffle, a rotating shaft, a first magnet and a second magnet. The second magnet and the first magnet are respectively connected to the top and bottom of the side of the water ski, and the top is rotatably connected to the rotating shaft, and the baffle is connected to the rotating shaft. The baffle is magnetically connected to the first magnet and the second magnet.

[0008] Preferably, a protective cover is further included. Both sides of the push plate are connected to the protective cover. The other end of the protective cover is connected to the inside of the water ski. The protective cover itself is foldable and is used to cover the screw rod and the guide rod.

[0009] Preferably, it further comprises a draw rope, one end of which is connected to the water ski board and is located at the opening of the cavity, and the other end of the draw rope is connected to the life buoy.

[0010] Preferably, a handle is further included, and the bottom of the baffle is connected to the handle.

[0011] Preferably, rollers are further included, and the water ski is placed in a cavity with a plurality of rollers connected therein.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The lifebuoy is pushed out through the screw rod and push plate, which solves the problem of low accuracy in throwing lifebuoys in traditional rescue. It is directly sent to the vicinity of the drowning person, realizing accurate delivery of the lifebuoy.

[0014] 2. Through the connection between the pull rope and the water ski, even if the person who falls into the water finds it difficult to immediately grab the lifebuoy in a panic state, the existence of the pull rope can ensure that the person who falls into the water can move with the water ski through it, solving the problem of difficulty in the person who falls into the water to cooperate.

[0020] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] Embodiment: A multifunctional rescue water ski, such as Figure 1-Figure 4 As shown, it includes a water ski 1, a servo motor 2, a screw rod 3, a guide rod 4, a push plate 5, a lifebuoy 6 and an opening and closing component. The water ski 1 is equipped with a power component and a controller for driving the water ski 1. A placement cavity is opened in the water ski 1, and the placement cavity is installed with the servo motor 2. One end of the screw rod 3 is connected to the output shaft of the servo motor 2, and the other end is rotatably connected to the water ski 1. The guide rod 4 is connected to the water ski 1. One end of the push plate 5 is threadedly connected to the screw rod 3, and the other end is slidably connected to the guide rod 4. A lifebuoy 6 is placed in the water ski 1. The servo motor 2 is connected to the controller by wire. An opening and closing component is provided at the opening of the placement cavity to prevent the lifebuoy 6 from sliding out of the water ski 1.

[0022] like Figure 2 and Figure 4 As shown, the opening and closing assembly includes a baffle 7, a rotating shaft 8, a first magnet 9 and a second magnet 10. The second magnet 10 and the first magnet 9 are connected to the top and bottom of the side of the water ski 1 respectively, and the top is rotatably connected to the rotating shaft 8, and the baffle 7 is connected to the rotating shaft 8. The baffle 7 is magnetically connected to the first magnet 9 and the second magnet 10.

[0023] After finding the person who falls into the water, the rescuer drives the water ski 1 close to the person who falls into the water, and relies on skilled driving technology to control the water ski 1 to sail quickly and accurately, and finally makes the opening of the cavity of the water ski 1 face the person who falls into the water, and calls the person who falls into the water. After hearing the voice, the person who falls into the water, regardless of whether he or she remains rational, will call for help in the direction of the human voice and rush to the direction with both hands. At this time, the servo motor 2 is turned on by the controller, and after the servo motor 2 is turned on, it drives the screw rod 3 to rotate, and the screw rod 3 pushes the push plate 5. The other end of the push plate 5 slides on the guide rod 4, gradually pushing out the lifebuoy 6. After the lifebuoy 6 presses against the baffle 7, the baffle 7 is squeezed. After the lifebuoy 6 presses against and squeezes the baffle 7, the baffle 7 rotates around the rotating shaft 8 due to the force, and the bottom gradually separates from the first magnet 9. , and finally maintains a stable position under the magnetic attraction of the second magnet 10, the lifebuoy 6 keeps moving smoothly, the rescuer controls the water ski 1 to make the lifebuoy 6 close to the person who falls into the water, and after the lifebuoy 6 is released, the person who falls into the water will grab the lifebuoy 6 at the moment of contact with the lifebuoy 6 and lie on the lifebuoy 6, and then gradually calm down. The rescuer then guides or assists the person who falls into the water to wear the lifebuoy 6 correctly, and leads the person who falls into the water to the shore through the water ski 1. After the person who falls into the water is rescued, the water remaining in the water ski 1 is dumped, the servo motor 2 is turned on, the servo motor 2 is reversed, and the push plate 5 is driven to reset inward by the reversed screw rod 3, and then the lifebuoy 6 is placed in the water ski 1, and the baffle 7 is pressed down. After the baffle 7 rotates 90 degrees, the bottom contacts the first magnet 9 and is magnetically attracted by it.

[0024] like Figure 2 As shown, a protective cover 11 is also included. The two sides of the push plate 5 are connected to the protective cover 11. The other end of the protective cover 11 is connected to the water ski 1. The protective cover 11 itself is foldable and is used to cover the screw rod 3 and the guide rod 4.

[0025] When the push plate 5 moves, the protective cover 11 connected to it is stretched and folded accordingly, always isolating the screw rod 3 and the guide rod 4 from the outside, ensuring that the working environment of the screw rod 3 and the servo motor 2 will not be corroded by water, thereby ensuring the stable working state of the servo motor 2 and the stable transmission cooperation between the screw rod 3 and the guide rod 4 and the push plate 5.

[0026] like Figure 2 As shown, it also includes a pull rope 12, one end of the pull rope 12 is connected to the water ski 1, located at the opening of the placement cavity, and the other end of the pull rope 12 is connected to the lifebuoy 6.

[0027] After the lifebuoy 6 leaves the water ski 1, there is still a pull rope 12 connecting it to the water ski 1. If the person who falls into the water fails to grab the lifebuoy 6 for the first time, the rescuers can adjust the position of the lifebuoy 6 in time through the water ski 1. In the subsequent rescue process, the person who falls into the water may not be able to grab the water ski 1 due to physical strength or other reasons and fall into the water again. The lifebuoy 6 connected by the pull rope 12 can pull the person who falls into the water in time, ensuring that the person who falls into the water can move with the water ski 1 in a short time, giving the rescuers time to react, stop and let the person who falls into the water hold the water ski 1 again, so there is no need to turn around or perform other operations. Even if the lifebuoy 6 is put under the armpits, the person who falls into the water only needs to lie on the lifebuoy 6 to move with the water ski 1 through the pull rope 12.

[0028] like Figure 2 As shown, a handle 13 is also included, and the bottom of the baffle 7 is connected to the handle 13.

[0029] The handle 13 extends outward, lengthening the force arm for pressing the baffle 7, thereby making it easier to overcome the magnetic attraction of the second magnet 10, making the action of covering the baffle 7 more labor-saving and convenient to operate.

[0030] like Figure 2 As shown, it also includes rollers 14, and the water ski 1 is placed in the cavity and connected to multiple rollers 14.

[0031] When pushing out the lifebuoy 6, the roller 14 can reduce the friction between the lifebuoy 6 and the water ski 1, thereby reducing the pressure on the push plate 5, ensuring that the push plate 5 can smoothly push out the lifebuoy 6, and at the same time optimize the transmission resistance between the screw rod 3 and the push plate 5, thereby extending the service life of the servo motor 2 and the screw rod 3.

[0032] After finding the person who falls into the water, the rescuer operates the multifunctional rescue water ski 1 equipped with a power component and a controller to approach quickly and accurately, aligning the placement cavity opening on the water ski 1 with the person who falls into the water. Then, the servo motor 2 is started through the controller to drive the screw 3 to rotate, pushing the push plate 5 to slide along the guide rod 4, and smoothly pushing out the lifebuoy 6. When the push plate 5 moves, the protective cover 11 stretches and folds accordingly to protect the screw rod 3 from water erosion. When the lifebuoy 6 is pushed out, the baffle 7 rotates under the action of magnetism to keep the lifebuoy 6 moving smoothly. At the same time, the pull rope 12 connects the lifebuoy 6 and the water ski 1 to ensure that the person who falls into the water can follow through the pull rope 12 even if he does not grab it immediately. After the person who falls into the water grabs the lifebuoy 6, the rescuer guides him to lie down and brings him back to the shore through the water ski 1. After the rescue is completed, the water on the water ski 1 is dumped, the servo motor 2 is reversed to reset the push plate 5, the lifebuoy 6 is put back in, and the baffle 7 is pressed down by the handle 13 to reset it. During the whole process, the roller 14 in the water ski 1 effectively reduces the friction between the lifebuoy 6 and the water ski 1, making the process of the push plate 5 pushing out the lifebuoy 6 smoother, and also optimizing the transmission efficiency between the screw rod 3 and the push plate 5, thereby ensuring the efficiency and smoothness of the rescue operation.
