Description

Technical Field

[0001] This utility model relates to the field of water salvage technology, and in particular to a foldable three-dimensional water salvage device. Background Technology

[0002] In the fields of fire rescue and water operations, the retrieval of drowning victims and the clearing of debris in rivers, lakes, and nearshore waters often face complex environmental challenges. Current mainstream retrieval tools, such as single hooks, nets, and simple grappling hooks, generally have the following technical shortcomings: traditional tools are mostly single-plane structures, and the retrieval range is limited to a single point or a single layer area. For complex situations such as sunken targets or entangled aquatic plants, multiple repeated operations are required to cover the target area, which is especially difficult in waters with rapid currents or low visibility.

[0003] Existing tools have fixed hook or net structures, making it impossible to adjust the gripping method according to the target object. In silty riverbeds, rocky areas, or areas with dense aquatic plants, the hook is prone to getting stuck, and uneven force can even damage the tool. Operators must directly control the tool with long poles or ropes, making it difficult to maintain stable direction under the impact of water currents. This not only increases physical exertion but also poses a safety risk due to tool rebound and sudden changes in drag force, especially during flood season or in complex waters, significantly increasing the risk of operators falling into the water. To improve structural strength, traditional salvage tools are mostly made of solid metal, generally weighing over 5kg, which is inconvenient for carrying and rapid deployment. Lightweight designs, on the other hand, suffer from weak resistance to water current impacts and are prone to deformation, making them unsuitable for long-term field operations. Underwater targets are often distributed at different depths and layers; traditional tools can only operate at a single depth, failing to achieve three-dimensional, all-around salvage, resulting in a high rate of missed targets.

[0004] To address the aforementioned issues and considering the design limitations of existing technologies, it is crucial to develop a water salvage device that combines three-dimensional coverage, strong environmental adaptability, ease of operation, and robust structure. This is a key requirement for improving water rescue efficiency and ensuring operational safety. Utility Model Content

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-5This utility model discloses a foldable three-dimensional water retrieval device, comprising: a horizontal pull rod 1, with eight mounting holes 11 on its outer surface, each mounting hole 11 having a detachable connecting ring 7. A search rope 8 is fixedly connected to the other end of each connecting ring 7, and a retrieval hook 9 is fixedly connected to the other end of each search rope 8. Each of the eight search ropes 8 has a float 10 on its surface at every other interval. A support rod 2 has an insertion interface 15 at one end, a positioning groove 13 at the center of the horizontal pull rod 1, and the insertion interface 15 is detachably connected to the positioning groove 13. The other end of the support rod 2 has an overlapping groove 14. A left diagonal support rod 4 is detachably connected to the left end of the horizontal pull rod 1, and a right diagonal support rod 3 is detachably connected to the right end of the horizontal pull rod 1. The other ends of the left and right diagonal support rods 4 and 3 are detachably connected to the top of the support rod 2. A lock 5 is provided at the top of the support rod 2, and a pull rope 6 is fixedly connected to the other end of the lock 5. Both ends of the support rod 2 are provided with connecting holes, and one of the eight mounting holes 11 is located inside the positioning groove 13. The connecting ring 7 passes through the connecting hole and the inside of the mounting hole 11. Both the left and right ends of the horizontal tie rod 1 are provided with buckle grooves 12, and the left diagonal brace 4 and the right diagonal brace 3 are respectively connected to the buckle grooves 12 on both sides.

[0025] The left diagonal brace 4 and the right diagonal brace 3 are connected to the two side latches 12 with pins. The support rod 2 is perpendicular to the horizontal tie rod 1, and the left diagonal brace 4 and the right diagonal brace 3 are the same length. The upper ends of the left diagonal brace 4, the right diagonal brace 3, and the support rod 2 are all provided with holes, and the locking buckle 5 connects them to each other through the holes in sequence. The horizontal tie rod 1, the left diagonal brace 4, and the right diagonal brace 3 can all be folded.

[0026] Working principle: The horizontal tie rod 1 serves as the basic load-bearing component in the horizontal direction. Its eight mounting holes 11 on its outer surface provide evenly distributed connection points for the hook and rope system, ensuring that the seven sets of search ropes 8 are equidistantly arranged in the horizontal direction, thus expanding the horizontal retrieval range. The positioning groove 13 in the center of the horizontal tie rod 1 is detachably connected to the insertion interface 15 of the support rod 2, forming a vertical cross structure that provides rigid support for the overall frame.

[0027] The support rod 2 is vertically connected to the middle of the horizontal tie rod 1. Its lower end is fixed by the insertion interface 15, and its upper end overlap groove 14 is connected to the left diagonal brace 4 and the right diagonal brace 3 to form a longitudinal support. The locking buckle 5 at its top locks the triangular frame through the hole that passes through itself and the diagonal brace, using the principle of triangular stability to resist the impact of water flow and ensure that the frame does not shake during operation.

[0028] The left diagonal brace 4 and the right diagonal brace 3 are connected at both ends to the buckle groove 12 of the horizontal tie rod 1 and the top of the support rod 2, respectively, and are fixed with pins to form an isosceles triangular auxiliary support structure. Both are of the same length, ensuring balanced force on the frame and preventing deformation due to excessive force on one side.

[0029] The connecting ring 7 is detachably fixed through the mounting hole 11 and the connecting hole of the support rod 2, allowing eight search ropes 8 to hang down and form a multi-dimensional grasping unit. The retrieval hook 9 is fixed to the end of the search rope 8 and adopts a multi-tooth barbed design. When it contacts the target object, it embeds itself into the surface of the object, such as clothing, seaweed, or debris, through dragging force to ensure a firm grip. When multiple hooks work together, they can simultaneously grasp targets in different positions, improving the efficiency of a single operation.

[0030] A buoy 10 is set at every other search rope 8, using buoyancy to suspend the corresponding search rope in the middle layer of water, forming a three-dimensional layout of "bottom-sinking hooks and middle-layer suspended hooks" to cover targets at different water depths.

[0031] The pull rope 6 is connected to the top of the frame via the locking buckle 5, forming a force transmission path. The operator can precisely adjust the retrieval position by controlling the extension and retraction of the pull rope 6. The left diagonal support rod 4, the right diagonal support rod 3, and the horizontal tie rod 1 are detachably connected to the buckle groove 12 via pins. When folding, the diagonal support rods can be rotated and stored by pulling out the pins. The horizontal tie rod 1 and the support rod 2 are separated via the positioning groove 13 and the insertion interface 15.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
