TECHNICAL FIELD

[0001] The application relates to the technical field of underwater rescue, in particular to an underwater rescue device capable of preventing waterweeds from being entangled. BACKGROUND

[0002] In the prior art, for example, the underwater rescue device capable of preventing waterweeds from being entangled disclosed in CN221698968U comprises an arc-shaped plate, bandages are arranged at the front and back ends of the bottom right side of the arc-shaped plate, and a handle is arranged at the bottom left side of the arc-shaped plate.

[0003] In this scheme, the arc-shaped plate is tied on the arm of a rescuer by the bandages, and the handle is held by hand. When it is necessary to cut the waterweeds, the first servo motor is started to drive the extension block and the frame body to move leftward as a whole, so that the cutters move toward the position where the waterweeds are entangled, until the waterweeds are located between the two cutters, and then the second servo motor is started to drive the two cutters to move relatively, so as to cut off the waterweeds, thereby achieving the purpose of cutting the waterweeds at a long distance, and avoiding the rescuer from being entangled by the waterweeds as much as possible.

[0004] However, in this scheme, the cutters are relatively moved to cut off the waterweeds, which may be difficult to accurately cut off the waterweeds due to the shaking of the waterweeds caused by the kicking of the rescued person during the actual rescue process, and the exposed cutters may easily injure the rescued person during the rescue.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] like Figures 1-4 As shown, an underwater rescue device for waterproofing grass entanglement according to an embodiment of this application includes a fixed cylinder 1 and a cutting mechanism 2. A telescopic cylinder 12 is coaxially and slidably inserted on the fixed cylinder 1, and an installation block 15 is fixedly connected to one end of the telescopic cylinder 12 extending out of the fixed cylinder 1.

[0024] Specifically, a sliding cavity 11 is coaxially arranged inside the fixed cylinder 1. Multiple limiting blocks 111 are circumferentially fixed to one end of the sliding cavity 11. Multiple sliding grooves 121 are evenly arranged circumferentially on the side wall of the telescopic cylinder 12. The sliding grooves 121 and the limiting blocks 111 slide in cooperation. In this way, the telescopic cylinder 12 can form an axial displacement inside the fixed cylinder 1.

[0025] Furthermore, a threaded cavity 122 is coaxially provided inside the telescopic cylinder 12, and a screw 13 is threadedly connected inside the threaded cavity 122. The screw 13 rotates through the fixed cylinder 1, and a motor 14 is fixedly connected to the end of the fixed cylinder 1. The output shaft of the motor 14 is keyed to the screw 13. Thus, the motor 14 can drive the screw 13 to rotate, and the rotation of the screw 13 can be used to drive the telescopic cylinder 12 to undergo axial displacement within the fixed cylinder 1. It should be noted that the motor 14 is a waterproof motor and has forward and reverse rotation functions.

[0026] In the specific embodiments of the present application, the fixing cylinder 1 is provided with a plurality of straps 16 on one side, and a handle 17 is fixed to the side wall of the fixing cylinder 1 near one end of the cutting mechanism 2, so as to facilitate the user to bind the fixing cylinder 1 on the arm and hold the direction of the fixing cylinder 1 through the handle 17. It should be noted that the handle 17 is provided with a control button (waterproof treatment, the related waterproof technology is prior art, which will not be described here), so as to facilitate the user to control the underwater rescue device.

[0027] As shown in Figure 1 , Figure 3 and Figure 4 , the cutting mechanism 2 includes a first strangulation assembly 21 and a second strangulation assembly 22 hinged to the fixing cylinder 1, and the first strangulation assembly 21 and the second strangulation assembly 22 are arranged above and below and connected in rotation. It should be noted that the first strangulation assembly 21 and the second strangulation assembly 22 are completely the same in structure and size.

[0028] Hereinafter, only the first strangulation assembly 21 will be described as an example, the first strangulation assembly 21 includes a mounting seat 211, a telescopic piece 212, a blade 213 and a protective plate 214, one end of the mounting seat 211 is hinged to the mounting block 15; one end of the telescopic piece 212 is hinged to the mounting block 15; the blade 213 is arranged on the side of the mounting seat 211 close to the second strangulation assembly 22; the protective plate 214 is fixed to the side of the mounting seat 211 away from the second strangulation assembly 22; the other end of the telescopic piece 212 is connected to the protective plate 214 in rotation.

[0029] Among them, the two blades 213 on the first strangulation assembly 21 and the second strangulation assembly 22 are gap-fitted in the upward direction.

[0030] It should be noted that the telescopic piece 212 in the first strangulation assembly 21 and the second strangulation assembly 22 can be an electric push rod or other related prior art, and the actual use of convenient carrying, installation, waterproof and the like is selected as the criterion.

[0031] Therefore, as shown in Figure 3 and Figure 4As shown, the telescopic members 212 in the two cutting-off assemblies synchronously drive the respective mounting seats 211 to synchronously and reversely rotate about the hinge points, so that the two blades 213 can relatively rotate to open or close to cover and cut off the water grass. It should be noted that the width of the protective plates 214 is greater than the width of the mounting seats 211 and the blades 213, that is, the protective plates 214 cover the mounting seats 211 and the blades 213 in width. As can be seen from the figure, the positions and coverage ranges of the two protective plates 214 are designed (the side of the protective plate 214 extending out of the blade 213 towards the corresponding blade), so that when the cutting mechanism 2 accidentally touches the human body, the protective plate 214 can avoid the blade 213 from causing accidental injury to the human body. In specific use, the telescopic cylinder 12 is controlled to be extended or retracted by controlling the control button on the handle 17, so that the rescue worker can be relatively far away from the water grass, and the first cutting-off assembly 21 and the second cutting-off assembly 22 are controlled to be opened to form a larger coverage range, so that the water grass to be cut off is located between the two cutting-off assemblies, and then the first cutting-off assembly 21 and the second cutting-off assembly 22 are controlled to be closed to cut off the water grass.

[0032] It should be noted that the specific model and specification of the screw rod 13, the motor 14, the telescopic member 212 and the blade 213 need to be determined according to the actual specification of the device, and the specific selection calculation method adopts the existing technology in the art, so it will not be described in detail.

[0033] The above is only a preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
