Description

Technical Field

[0001] This utility model relates to the field of salvage technology, and in particular to an underwater salvage device. Background Technology

[0002] With the widespread use of personal electronic devices (such as mobile phones), accidental water-related incidents have become a frequent source of anxiety. Taking the typical scenario of a mobile phone falling into a 3-meter-deep silty lake as an example, the user's core need is to ensure their own safety while avoiding economic losses and data loss (such as personal information and important files on the phone). However, the unique characteristics of this scenario (deep water, silt, and turbid water) directly render traditional salvage methods completely ineffective, creating a clear technological gap. Existing salvage solutions are mostly designed for "large loads and open water" scenarios such as marine engineering and emergency rescue, lacking specialized tools suitable for "personal operation, shallow silty water environments, and small targets." This has spurred the demand for lightweight, low-cost, and easy-to-operate salvage devices.

[0003] Currently available gripping devices are difficult to use in murky lake water due to reduced visibility, making it hard to retrieve lost mobile phones and other items. Furthermore, existing gripping devices are not easy to adjust in length according to the depth of the lake water, making them impractical. Therefore, we have developed an underwater item retrieval device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an underwater item retrieval device, which solves the technical problems of existing gripping devices being difficult to retrieve lost mobile phones and other items in murky lake water due to visibility limitations, and also being impractical because existing gripping devices are difficult to adjust in length according to the depth of the lake water.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An underwater object retrieval device includes a sleeve with an inner cylinder movably disposed inside the sleeve. A mounting block is fixedly connected to one end of the inner cylinder. A gripping assembly is disposed on one side of the mounting block. A pulling assembly is disposed at one end of the sleeve. A camera is fixedly mounted on one side of the mounting block. A connecting cable is fixedly connected to one side of the camera. A display screen is fixedly connected to one end of the connecting cable. The display screen is fixedly connected to the sleeve.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model uses a positioning component to bind the binding rope to the hanging ring. Pulling the positioning rod outward until one end of the positioning rod disengages from the positioning hole on the surface of the inner cylinder allows for length adjustment of the device. During adjustment, the limiting groove restricts the position of the inner cylinder, making it more stable during adjustment. After adjustment, the positioning rod is released, and under the restoring force of the spring, it enters the nearest positioning hole to fix the inner cylinder. Then, the binding rope is tied to the hanging ring and kept taut to achieve length adjustment of the device.

[0019] 2. This utility model, by setting up a gripping assembly and a pulling assembly, firstly, one end of the binding rope is tied to the second hanging ring, and then the other end of the binding rope is tied to the first hanging ring, making the binding rope taut. Only then can the gripper part be inserted into the lake to grab the mobile phone. At the same time, the camera can capture images of the lake water so that people can locate the object on the display screen for easy grabbing. By squeezing the handle with your hand, the handle will compress the spring. At this time, the binding rope is stretched and its other end will pull the sliding rod. At this time, the return spring is compressed and the rotating rod will be subjected to a downward force. Under this force, multiple grippers move towards the center to grab the mobile phone. During this process, the rubber pad can prevent damage to the mobile phone during the grabbing process. After the mobile phone is taken out of the lake, release the rotating handle. At this time, the binding rope is no longer under tension, the return spring returns to its original state, the grippers are released, and the mobile phone can be taken out.

[0028] The technical solution in this application embodiment effectively solves the problems of existing gripping devices, which are difficult to use in murky lake water due to visibility limitations, and also have low practicality because they are difficult to adjust in length according to the depth of the lake. The overall idea is as follows:

[0029] like Figures 1 to 6 To address the problems existing in the prior art, this utility model provides an underwater object retrieval device, including a sleeve 11, an inner cylinder 12 movably disposed inside the sleeve 11, a mounting block 14 fixedly connected to one end of the inner cylinder 12, a gripping assembly 2 disposed on one side of the mounting block 14, a pulling assembly 4 disposed at one end of the sleeve 11, a camera 31 fixedly mounted on one side of the mounting block 14, a connecting wire 32 fixedly connected to one side of the camera 31, a display screen 33 fixedly connected to one end of the connecting wire 32, the display screen 33 being fixedly connected to the sleeve 11, and a positioning assembly 13 disposed between the sleeve 11 and the inner cylinder 12.

[0030] Specifically, the positioning component 13 includes a fixing block 131 fixedly connected to the outside of the sleeve 11, a positioning rod 132 inserted inside the fixing block 131, a limiting piece 133 fixedly connected to the outside of the positioning rod 132, a spring 134 fixedly connected between the limiting piece 133 and the fixing block 131, a limiting groove 111 opened on the inner side of the sleeve 11, a slider that slides and engages with the limiting groove 111 is provided on the outside of the inner cylinder 12, and a plurality of positioning holes corresponding to the positioning rod 132 are opened on the surface of the inner cylinder 12.

[0031] By adopting the above technical solution, firstly, the binding rope 5 is brought into contact and bound to the hanging ring 44. Then, the positioning rod 132 is pulled outward until one end of the positioning rod 132 is disengaged from the positioning hole on the surface of the inner tube 12. Only then can the length of the device be adjusted. During the adjustment process, the limiting groove 111 can restrict the position of the inner tube 12, making it more stable during the adjustment process. After the adjustment is completed, the positioning rod 132 is released. Under the action of the restoring force of the spring 134, the positioning rod 132 enters the nearest positioning hole, thus fixing the inner tube 12. Then, the binding rope 5 is tied to the hanging ring 44 and the binding rope 5 is kept taut to achieve the length adjustment of the device.

[0032] Specifically, the gripper assembly 2 includes multiple support plates 21 fixedly connected to one side of the mounting block 14. A gripper 22 is rotatably mounted on one end of each support plate 21. A rotating rod 24 is rotatably mounted on the outside of the gripper 22. A connecting block 25 is rotatably connected to one end of the rotating rod 24. A base plate 26 is fixedly connected to one side of the connecting block 25. A sliding rod 27 is fixedly connected to the middle of one side of the base plate 26. A pressing plate 28 is fixedly connected to one end of the sliding rod 27. A hanging ring 20 is fixedly connected to one side of the pressing plate 28. A second hanging ring 20 is fixedly connected to one side of the pressing plate 28. There is a return spring 29, one end of which is fixedly connected to a limit plate 211. The limit plate 211 is fixedly connected to multiple support plates 21. A rubber pad 23 is fixedly connected to the inner side of the gripper 22. The pulling assembly 4 includes a handle 41 fixedly connected to one end of the sleeve 11. A rotating handle 42 is rotatably installed inside the handle 41. A spring 43 is fixedly connected between the handle 41 and the rotating handle 42. A first hanging ring 44 is fixedly connected to one side of the rotating handle 42. A binding rope 5 is tied between the first hanging ring 44 and the second hanging ring 20.

[0033] By adopting the above technical solution, firstly, one end of the binding rope 5 is tied to the second hanging ring 20, and then the other end of the binding rope 5 is tied to the first hanging ring 44, so that the binding rope 5 is in a taut state. Only then can the claw 22 be inserted into the lake to grab the mobile phone. At the same time as grabbing, the camera 31 can capture the lake water, so that people can locate the object through the display screen 33 to grab it. By squeezing the rotating handle 42 with force, the rotating handle 42 will compress the spring 43. At this time, the binding rope 5 is stretched and its other end will pull the slide bar 27. At this time, the return spring 29 is compressed and the rotating rod 24 will be subjected to a downward force. Under this force, the multiple claws 22 move towards the center to grab the mobile phone. During this process, the rubber pad 23 can prevent damage to the mobile phone during the grabbing process. After the mobile phone is taken out of the lake, the rotating handle 42 is released. At this time, the binding rope 5 is no longer under force, the return spring 29 returns to its original state, the claws 22 are released, and the mobile phone can be taken out.

[0034] Working principle: In use, firstly, one end of the binding rope 5 is tied to the second hanging ring 20, and then the other end of the binding rope 5 is tied to the first hanging ring 44, making the binding rope 5 taut. Then, the gripper 22 can be inserted into the lake to grab the phone. Simultaneously, the camera 31 can capture images of the lake water, allowing users to locate the object on the display screen 33 for easy grabbing. Squeezing the handle 42 compresses the spring 43, stretching the binding rope 5 and pulling the sliding rod 27. The return spring 29 is compressed, and the rotating rod 24 is subjected to a downward force. This force causes the multiple grippers 22 to move towards the center, thus grabbing the phone. During this process, the rubber pad 23 prevents damage during the grabbing of the phone. After the device is removed from the lake, release the rotating handle 42. At this time, the binding rope 5 is no longer under force, the return spring 29 returns to its original state, and the gripper 22 releases, allowing the phone to be removed. When adjusting the length of the device, first, bind the binding rope 5 to the hanging ring 44, and pull the positioning rod 132 outward until one end of the positioning rod 132 disengages from the positioning hole on the surface of the inner tube 12 before adjusting the length of the device. During the adjustment process, the limiting groove 111 can restrict the position of the inner tube 12, making it more stable during the adjustment process. After the adjustment is completed, release the positioning rod 132. Under the action of the restoring force of the spring 134, the positioning rod 132 enters the nearest positioning hole, thus fixing the inner tube 12. Then, bind the binding rope 5 to the hanging ring 44 and keep the binding rope 5 taut to achieve the length adjustment of the device.

[0035] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
