Description

Technical Field

[0001] This utility model relates to the technical field of salvage tools, and in particular to a water salvage device. Background Technology

[0002] Currently, in emergency rescue operations in rivers, lakes, and other waterways, firefighters and rescue personnel often use handheld salvage tools to clear or retrieve floating objects from the water surface. Traditional water salvage tools typically consist of a handheld pole fixedly connected to a functional salvage head.

[0003] However, most existing salvage tools use fixed, rigid poles, typically 2-3 meters long. When floating objects are far from the shore, the limited pole length makes it difficult for rescuers to reach them, requiring them to wade through the water or use boats, greatly increasing the operational risks. If the pole is designed to be too long, it will increase the weight of the salvage tool, making it difficult for firefighters to lift. In addition, salvage tools take up a lot of space when not in use, making them inconvenient to store and carry. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a water salvage device that solves the operational risks and storage problems caused by the insufficient or excessive length of traditional handheld poles, as well as reducing the difficulty of operation.

[0031] A water salvage device according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0032] Reference Figure 1 The present invention aims to provide an embodiment of a water salvage device.

[0033] A water salvage device according to an embodiment of the present invention includes a salvage head 100 and a telescopic rod. The salvage head 100 is used to salvage floating objects on the water. The telescopic rod includes a first hollow rod 110, a second hollow rod 120, and a locking structure 130. The salvage head 100 is installed at one end of the first hollow rod 110. The radial outer surface of the first hollow rod 110 matches the inner surface of the second hollow rod 120, and the second hollow rod 120 and the first hollow rod 110 are slidably disposed relative to each other. The locking structure 130 is disposed between the first hollow rod 110 and the second hollow rod 120, and the locking structure 130 is used to connect and fix the second hollow rod 120 and the first hollow rod 110.

[0034] It is understood that this embodiment, by setting the first hollow rod 110, the second hollow rod 120, and the locking structure 130, allows the first hollow rod 110 and the second hollow rod 120 to slide relative to each other. Therefore, the length of the telescopic rod can be changed. After the length of the telescopic rod is adjusted, the first hollow rod 110 and the second hollow rod 120 can be locked and fixed by the locking structure 130. Thus, during salvage operations, the telescopic rod can be extended to facilitate firefighters in salvaging floating objects far from the shore. When not in use, the telescopic rod can be shortened to reduce the length of the salvage tool, reduce the space occupied, and facilitate storage and carrying.

[0035] A water salvage device according to an embodiment of the present invention further includes a float 140, which is connected to the side of the salvage head 100 away from the first hollow rod 110. The float 140 is used to prevent the salvage head 100 from sinking into the water.

[0036] It is understandable that, in this embodiment, by setting up a floating body 140, after the telescopic rod is extended, due to the long lever arm of the telescopic rod, it is very difficult for firefighters to hold the end of the telescopic rod for retrieval work. The floating body 140 can effectively prevent the retrieval head 100 from sinking into the water due to its weight, ensuring the stability of the retrieval operation and reducing the difficulty of the operation for firefighters.

[0037] In some embodiments of this utility model, the locking structure 130 includes a locking nut 150 and a sleeve 160. The locking nut 150 is threadedly connected to the outer surface of the end of the second hollow rod 120. The sleeve 160 is fitted onto the first hollow rod 110 and located inside the locking nut 150. The sleeve 160 can elastically deform to clamp the first hollow rod 110. The locking nut 150 is provided with an abutment portion 170. The sleeve 160 is provided with a convex ring 180 that abuts against the end of the first hollow rod 110. A wedge-shaped inclined surface 190 is provided between the abutment portion 170 and the convex ring 180.

[0038] It is understood that in this embodiment, by setting a locking nut 150 and a sleeve 160, the locking nut 150 is tightened with the outer surface of the second hollow rod 120, so that the abutment part 170 and the convex ring 180 are in contact and engaged through the wedge-shaped inclined surface 190, and the sleeve 160 undergoes elastic deformation to clamp the first hollow rod 110, thereby connecting and fixing the second hollow rod 120 and the first hollow rod 110.

[0039] The locking nut 150 is loosened from the outer surface of the second hollow rod 120, and the first hollow rod 110 can slide within the sleeve 160. Thus, the length of the telescopic rod can be freely changed, making it simple and convenient to change the length of the telescopic rod itself.

[0040] In some embodiments of this utility model, a through groove 200 is provided on the outer surface of the sleeve 160, and the through groove 200 extends along the end of the sleeve 160.

[0041] It should be noted that the sleeve 160 can be made of plastic, and the through groove 200 enhances the elastic deformation ability of the sleeve 160, so that the sleeve 160 firmly clamps the first hollow rod 110.

[0042] Multiple through slots 200 can be provided, and the multiple through slots 200 are evenly distributed to bear the force, avoiding local stress concentration that could damage the jacket 160.

[0043] In some embodiments of this utility model, a straight channel 210 is provided on the inner surface of the second hollow rod 120. The straight channel 210 extends along the length direction of the second hollow rod 120. A limit buckle 220 is provided at the end of the first hollow rod 110. The limit buckle 220 can move along the straight channel 210 to prevent the first hollow rod 110 and the second hollow rod 120 from rotating relative to each other.

[0044] Understandably, the straight section 210 and the limit buckle 220 work together to restrict the relative rotation of the rod, ensuring the stability of the retrieval head 100 in the direction of the rod and improving the accuracy of the operation.

[0045] In some embodiments of this utility model, the buoy 140 is made of foam material.

[0046] Understandably, foam material is lightweight and highly buoyant, reducing overall weight and facilitating retrieval operations. Furthermore, foam material is highly water-resistant and does not easily corrode or absorb water and increase weight over long-term use.

[0047] In some embodiments of this utility model, the floating body 140 has a cuboid structure. In the length direction, the floating body 140 is symmetrically arranged about the first hollow rod 110. It can be understood that the symmetrical cuboid floating body 140 provides balanced buoyancy to prevent the retrieval head 100 from tilting and causing it to become detached.

[0048] In some embodiments of this utility model, the retrieval head 100 includes a frame 230 and a plurality of hook assemblies 240 connected to the frame 230, with the plurality of hook assemblies 240 disposed on the same side of the frame 230.

[0049] It is understandable that by setting up the frame 230 and multiple hook assemblies 240, the multiple hook assemblies 240 expand the salvage area and improve the efficiency of a single operation. The hook assemblies 240 are concentrated on the same side of the frame 230 to enhance the gripping force on floating objects.

[0050] In some embodiments of this utility model, the hook assembly 240 includes a connecting rod 250 and three barbs 260 connected to the connecting rod 250. The end of the connecting rod 250 is rotatably mounted on the frame 230. The three barbs 260 are distributed circumferentially along the connecting rod 250. It can be understood that the three barbs 260 are distributed circumferentially to form a three-dimensional enclosure, which can adapt to the needs of grabbing floating objects of different shapes and orientations.

[0051] In some embodiments of this utility model, the frame 230 has a triangular structure, and a sleeve 270 is provided at the corner of the frame 230. The sleeve 270 is fitted onto the first hollow rod 110, and the sleeve 270 and the first hollow rod 110 are connected by bolts 280.

[0052] Understandably, the triangular frame 230 is lightweight and has strong resistance to deformation. In addition, the sleeve 270 and the first hollow rod 110 are connected by bolts 280, which facilitates quick disassembly and assembly of the retrieval head 100 and makes it convenient for maintenance or replacement of parts.

[0053] In some embodiments of this utility model, a handle 290 is provided at the end of the second hollow rod 120 away from the locking structure 130, so that firefighters can hold the handle 290 to improve grip comfort and reduce fatigue during long-term operation.
