Description
Technical Field
[0001] This utility model relates to the field of fire-fighting salvage technology, specifically to an underwater salvage tool. Background Technology
[0002] Underwater salvage equipment is used for maritime salvage and underwater object retrieval. In the firefighting field, it is mainly used to search for and retrieve items belonging to people who have fallen into the water and to clear underwater objects. Common salvage tools on the market include clamping salvage tools composed of multiple claws to grab items, and magnetic salvage tools with strong magnets connected by ropes to retrieve magnetic objects that have fallen into the water.
[0003] However, existing underwater salvage tools, whether clamping or magnetic, have difficulty gripping and salvaging smooth, non-magnetic materials such as mobile phones and wallets. Furthermore, they cannot monitor the gripping status of the salvage tool, resulting in poor salvage performance. This solution addresses this technical problem. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an underwater salvage tool. When the pull plate drives the traction rope to lift the abutment plate, the steel wires in the grabbing mechanism elastically converge, and multiple steel wires simultaneously hold the salvaged object into the arc-shaped cover. This avoids the disadvantage of clamp-type salvage tools having unstable clamping. The salvage tool is effective for salvaging hard and smooth non-magnetic objects such as mobile phones and wallets.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an underwater salvage tool, including a pole, a gripping mechanism disposed at one end of the pole, and an operating handle disposed at the other end of the pole, wherein the operating handle is connected to the gripping mechanism;
[0006] The gripping mechanism includes an arc-shaped cover connected to the rod body at one end, several steel wires arranged in a parallel array at the other end of the arc-shaped cover, and an abutment plate slidably disposed inside the arc-shaped cover. The edge of the abutment plate is separably abutted against the steel wires. A traction rope is connected between the other end of the abutment plate and the operating handle. A compression spring is sleeved on the outside of the traction rope. One end of the compression spring abuts against the inside of the arc-shaped cover, and the other end of the compression spring is connected to the abutment plate.
[0007] The rod is also equipped with a monitoring mechanism for monitoring the gripping mechanism.
[0008] The rod body includes an outer tube and an inner tube that is slidably disposed on the inner side of one end of the outer tube. The operating handle is connected to the other end of the outer tube. The other end of the inner tube is provided with a ball head. The arc-shaped cover is provided with a receiving groove for accommodating the ball head. The outer side of the inner tube is fitted with a locking sleeve that is connected to the receiving groove. The arc-shaped cover is movably connected to the inner tube through the ball head in the receiving groove. The traction rope passes through the receiving groove, the ball head, the inner tube and the outer tube in sequence and is connected to the operating handle.
[0009] The operating handle includes a grip ring connected to the outer tube and a pull plate disposed within the grip ring, the pull plate being connected to the traction rope.
[0010] A permanent magnet is provided on the bottom side of the abutment plate.
[0011] The monitoring mechanism includes a camera mounted on the inner tube near the gripping mechanism and a display mounted on the outer tube near the handle. The display and the camera are connected by a cable.
[0012] The cable is equipped with an automatic telescopic cable reel.
[0013] A locking ring is provided between the outer tube and the inner tube, and the outer tube and the inner tube are connected by the locking ring.
[0014] A limiting sleeve is provided inside the arc-shaped cover, and a guide sleeve is provided on one side of the abutting plate. The abutting plate is slidably disposed inside the limiting sleeve of the arc-shaped cover through the guide sleeve.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] (1) When the pull plate drives the traction rope to pull the abutment plate upward, the steel wires in the grabbing mechanism elastically close together, and multiple steel wires simultaneously grab the salvaged object into the arc-shaped cover, avoiding the disadvantage of the clamping type salvage tool not being firmly clamped. The salvage tool has a better salvage effect on hard and smooth non-magnetic salvage objects such as mobile phones and wallets.
[0017] (2) By using the monitor and camera of the monitoring agency, the salvage process is clearly visible and the salvage efficiency is higher.
[0018] (3) By setting the ball head, the grabbing mechanism can rotate at the bottom of the water. When the rod is tilted down to the water, the rotation of the grabbing mechanism makes the contact plate fit the object being retrieved more closely, thus making the steel wire grabbing the object being retrieved better.
[0019] (4) By setting permanent magnets on the abutment plate and using steel wires to grab the salvaged object, the salvage effect is better for larger and heavier weakly magnetic salvage objects. Attached Figure Description

[0025] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.
[0026] See Figure 1 - Figure 4 An underwater salvage tool includes a pole 1, a gripping mechanism 2 disposed at one end of the pole 1, and an operating handle 3 disposed at the other end of the pole 1, wherein the operating handle 3 is connected to the gripping mechanism 2.
[0027] The gripping mechanism 2 includes an arc-shaped cover 21 connected to the rod 1 at one end, several steel wires 22 arranged in a parallel array at the other end of the arc-shaped cover 21, and an abutment plate 23 slidably disposed inside the arc-shaped cover 21. The edge of the abutment plate 23 is detachably abutted against the steel wires 22. A traction rope 24 is connected between the other end of the abutment plate 23 and the operating handle 3. A compression spring 25 is sleeved on the outside of the traction rope 24. One end of the compression spring 25 abuts against the inside of the arc-shaped cover 21, and the other end of the compression spring 25 is connected to the abutment plate 23.
[0028] The rod 1 is also equipped with a monitoring mechanism 5 for monitoring the gripping mechanism 2.
[0029] The rod body 1 includes an outer tube 11 and an inner tube 12, one end of which is slidably disposed inside the outer tube 11. The operating handle 3 is connected to the other end of the outer tube 11. The other end of the inner tube 12 is provided with a ball head 13. The arc-shaped cover 21 is provided with a receiving groove 211 for accommodating the ball head 13. The outer side of the inner tube 12 is fitted with a locking sleeve 121 connected to the receiving groove 211. The arc-shaped cover 21 is movably connected to the inner tube 12 through the ball head 13 in the receiving groove 211. The traction rope 24 passes through the receiving groove 211, the ball head 13, the inner tube 12 and the outer tube 11 in sequence and is connected to the operating handle 3.
[0030] The operating handle 3 includes a grip ring 31 connected to the outer tube 11 and a pull plate 32 disposed within the grip ring 31. The pull plate 32 is connected to the traction rope 24.
[0031] A permanent magnet 4 is provided on the bottom side of the abutment plate 23.
[0032] The monitoring mechanism 5 includes a camera 51 installed on the inner tube 12 near the gripping mechanism 2, and a display 52 installed on the outer tube 11 near the handle. The display 52 and the camera 51 are connected by a cable 53.
[0033] The cable 53 is equipped with an automatic telescopic cable reel 54.
[0034] A locking ring 14 is provided between the outer tube 11 and the inner tube 12, and the outer tube 11 and the inner tube 12 are connected by the locking ring 14.
[0035] The arc-shaped cover 21 is provided with a limiting sleeve 212, and a guide sleeve 231 is provided on one side of the abutting plate 23. The abutting plate 23 is slidably disposed in the limiting sleeve 212 of the arc-shaped cover 21 through the guide sleeve 231.
[0036] The specific working process and principle of this utility model:
[0037] Pull the inner tube 12 out of the outer tube 11 by a certain length, then tighten the locking ring 14 to lock the inner tube 12. At the same time, the automatic telescopic cable reel 54 stretches the cable 53 to a certain length and then locks the cable 53. Start the monitoring mechanism 5, hold the gripping ring 31 and lower the grabbing mechanism 2 underwater. Observe the image collected by the camera 51 of the monitoring mechanism 5 through the display 52. Lower the arc-shaped cover 21 with the salvage object and ensure that the abutment plate 23 is directly above the salvage object. When the grabbing mechanism 2 continues to be lowered to the bottom of the water, the steel wire 22 contacts the bottom of the water under the support of the abutment plate 23, thereby driving the entire arc-shaped cover 21 to rotate along the ball head 13, so that the abutment plate 23 fits against the salvage object at the bottom of the water.
[0038] Holding the grip ring 31, pull the pull plate 32. The pull plate 32 pulls the abutment plate 23 upward through the traction rope 24, overcoming the elastic force of the compression spring 25. At the same time, the guide sleeve 231 connected to the abutment plate 23 slides in the limiting sleeve 212. The steel wire 22 gradually converges towards the center of the abutment plate 23 and grabs the salvaged object below the abutment plate 23. When the abutment plate 23 rises into the inside of the arc-shaped cover 21, the steel wire 22 completely converges and resets, sealing the salvaged object in the space between the steel wire 22 and the arc-shaped cover 21. There are a large number of steel wires 22. When the steel wires 22 converge, smaller salvaged objects can be salvaged. The initial shape of the steel wire 22 is similar to a steel wire 22 head massager, in the state of converged ends.
[0039] Finally, the rod 1 is raised by holding the ring 31 to retrieve the salvage object. Then, the pull plate 32 is released, and the abutment plate 23 is stretched open by the spring force of the compression spring 25. Finally, the salvage object is taken out, and the operation of the salvage tool is completed.
[0040] The bottom of the receiving plate 23 is equipped with a permanent magnet, which can attract ferromagnetic salvage objects. Combined with the elastic folding of the steel wire 22, larger salvage objects can be retrieved.
[0041] When the pull plate 32 drives the traction rope 24 to pull the abutment plate 23 upward, the steel wires 22 in the grabbing mechanism 2 elastically close together, and multiple steel wires 22 simultaneously grab the salvaged object into the arc-shaped cover 21, avoiding the disadvantage of the clamping type salvage tool not being able to hold firmly. The salvage tool has a better salvage effect on hard and smooth non-magnetic salvage objects such as mobile phones and wallets.
[0042] The monitoring device 5's display 52 and camera 51 work together to make the salvage process clearly visible and the salvage efficiency higher.
[0043] By setting the ball head 13, the grabbing mechanism 2 can rotate underwater. When the rod 1 is tilted down to the water, the rotation of the grabbing mechanism 2 makes the abutment plate 23 fit more closely with the object to be retrieved, thereby making the steel wire 22 grab the object to be retrieved better.
[0044] By using the permanent magnet 4 on the receiving plate 23, and in conjunction with the steel wire 22 to grab the salvaged object, the salvage effect is better for larger and heavier weakly magnetic objects.
[0045] The automatic retractable cable reel 54 serves to store the cable 53. The cable 53 wound on the reel can extend and retract back and forth. It has a self-locking device and an automatic cable routing function. After pulling out a section of the cable, the self-locking device takes effect. If you want to retract the cable, you need to pull out another section of the cable. The cable passes over the self-locking device and is released. The cable automatically retracts. The automatic retractable cable reel 54 is implemented using existing technology and will not be described in detail here.
[0046] The technical features of this utility model not described can be implemented by or by using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
