Description

Technical Field

[0001] This utility model relates to the field of metal detection equipment technology, and in particular to a marine underwater metal positioning and detection rod. Background Technology

[0002] With the rapid development of marine science and technology and the marine economy, the exploration and development of the ocean has spread to all areas of the ocean. In fields such as underwater engineering, marine exploration, and underwater salvage, it is often necessary to detect and locate metal targets to accurately find desired metal objects, such as underwater buried metal oil and gas pipelines, shipwrecks, and metal mineral resources. Therefore, metal detectors are needed to detect underwater metal targets. Metal detectors are mainly divided into three categories: electromagnetic induction type, X-ray detection type, and microwave detection type. Metal detectors are electronic instruments used to detect metal targets and can be used to accurately detect underwater metal targets.

[0003] Metal detectors are typically towed by a vessel, moving as they travel to detect underwater metal targets. Because the electromagnetic waves emitted by metal detectors attenuate significantly underwater, their detection range is limited. The detector needs to be relatively close to the seabed, generally between ten and twenty meters, to accurately detect underwater metal targets. However, this close detection distance presents significant safety hazards during detection, such as collisions with reefs or uneven terrain, which can easily damage the detector. Furthermore, the limited adjustment of the underwater detection range makes underwater metal detection inconvenient, leading to missed targets and affecting the overall effectiveness of underwater metal detection. Utility Model Content

[0004] To address the technical problems of existing technologies, such as the relatively short detection distance leading to significant safety hazards during metal detector detection, and the inconvenience of adjusting the underwater detection range, which affects the effectiveness of underwater metal detection, this utility model provides the following technical solution.

[0005] This utility model discloses a marine underwater metal positioning and detection rod, comprising a rod body and a towing rope fixedly connected to the upper end of the rod body. The upper part of the rod body is provided with a drive chamber and a power chamber. At least one sonar component for terrain detection is fixedly connected to the outside of the rod body and connected to the power chamber. The rod body is provided with a sliding groove, and a lifting rod with an axially threaded hole is slidably connected to the sliding groove. A lead screw motor is fixedly provided in the inner cavity of the drive chamber, and the output end of the lead screw motor is connected to a lead screw. The lead screw extends into the sliding groove and is threadedly connected to the threaded hole. The lower end of the lifting rod is connected to a swinging component and a metal detector connected to the swinging component.

[0006] As a further technical solution, the swing component includes a sealing frame fixedly connected to the lower end of the lifting rod and a rotary motor located in the inner cavity of the sealing frame. The output end of the rotary motor is fixedly connected to a swing plate, and the swing plate is fixedly connected to the metal detector.

[0007] As a further technical solution, the swing plate is inclined to the axis of the output end of the rotary motor.

[0008] As a further technical solution, the lifting rod has a non-cylindrical cross-section that matches the sliding groove.

[0009] As a further technical solution, a limit switch is provided at the lower part of the lifting rod.

[0010] As a further technical solution, a sealing gasket is provided at the lower end of the slide groove to abut against the lifting rod.

[0011] The beneficial effects of this invention are as follows: A sonar component is fixedly connected to the outer side of the pole, enabling real-time monitoring of the underwater terrain. This allows for adjustment of the height and direction of the pole under the tow rope, achieving terrain-mimicking monitoring by the metal detector. This results in more accurate metal detection and improved metal detection efficiency. When the sonar component is monitoring the terrain in real time, if there is a significant safety hazard ahead, the tow rope can be raised directly, or the lifting pole can be raised and lowered relative to the pole body to prevent damage to the metal detector from underwater reefs or large terrain undulations. A metal detector driven by a swinging component is located at the lower end of the lifting pole, allowing for multi-directional rotation and easy adjustment of the underwater detection range. This prevents missed detections and improves the effectiveness of underwater metal detection. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0018] In the description of this utility model, it should be understood that the terms "upper" and "lower" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0019] like Figure 1 As shown, this utility model discloses a marine underwater metal positioning and detection rod, comprising a rod body 4 and a towing rope 1 fixedly connected to the upper end of the rod body 4. The towing rope 1 is connected to the hull. When the hull moves on the water surface, the towing rope 1 drives the rod body 4 to move underwater for metal detection. The upper part of the rod body 4 is provided with a drive compartment 3 and a power compartment 2. The rod body 4 can be integrally formed with the drive compartment 3 and the power compartment 2, or it can be sealed and fixed by bolts. The power compartment 2 contains a battery and a controller. The controller contains a wireless transmission module or a wired transmission module, which is controlled by personnel on the ship.

[0020] In a preferred embodiment, at least one sonar component 5 for terrain detection is fixedly connected to the outer side of the rod 4 and electrically connected to the power supply compartment 2. The sonar component 5 adopts existing technology and can perform sonar detection underwater, providing feedback signals of obstacles in the water to facilitate the guidance of the metal detector 8's movement direction and prevent the metal detector 8 from hitting reefs. When the metal detector 8 detects metal, the sonar component 5 can accurately locate the metal's position.

[0021] like Figure 2 and Figure 3As shown, in a preferred embodiment, the rod body 4 is provided with a groove 401, and a lifting rod 6 with an axially threaded hole 601 is slidably connected to the groove 401. The lifting rod 6 has a non-cylindrical cross-section that matches the groove 401 to prevent the lifting rod 6 from rotating radially within the groove 401. A lead screw motor 301 is fixedly installed inside the drive chamber 3, and the output end of the lead screw motor 301 is connected to a lead screw 302. The lead screw 302 extends into the groove 401 and is threadedly connected to the threaded hole 601. Thus, the lead screw motor 301 can drive the lifting rod 6 to move up and down relative to the rod body 4 within the groove 401, preventing the metal detector 8 at the lower end of the lifting rod 6 from being damaged by contact with a rock.

[0022] A sealing gasket is provided on the inner side of the lower end of the slide 401 to abut against the lifting rod 6, so as to prevent water from entering the slide 401. A limit switch 602 is provided at the lower part of the lifting rod 6, and a limit switch is also provided in the slide 401 to prevent the lifting rod 6 from being excessively raised or lowered and damaging the rod body 4.

[0023] like Figure 4 As shown, in a preferred embodiment, a swing component 7 is connected to the lower end of the lifting rod 6, and a metal detector 8 is connected to the lower part of the swing component 7. The metal detector 8 adopts an existing structure and can detect underwater metals. The swing component 7 includes a sealing frame 701 fixedly connected to the lower end of the lifting rod 6. A rotary motor 702 is installed inside the cavity of the sealing frame 701. The opening of the sealing frame 701 shown in the figure is only for illustration; the actual sealing frame 701 is a sealed structure to prevent water from adversely affecting the rotary motor 702. A swing plate 703 is fixedly connected to the output end of the rotary motor 702, and the swing plate 703 is fixedly connected to the metal detector 8. The rotary motor 702 can drive the metal detector 8 to rotate in multiple directions, which facilitates the adjustment of the detection range of the metal detector 8 underwater.

[0024] Preferably, the oscillating plate 703 is inclined to the axis of the output end of the rotary motor 702. When the oscillating plate 703 rotates, it can drive the metal detector 8 to rotate and detect more directions, thereby further improving the detection range of the metal detector 8.

[0025] In use, the tow rope 1 moves with the boat, and the swinging component 7 drives the metal detector 8 to rotate for multi-directional metal detection. Simultaneously, the sonar component 5 monitors the underwater terrain in real time. When the metal detector 8 detects metal, the sonar component 5 records the location of the detected metal. When the sonar detects a large obstacle ahead, the tow rope 1 is pulled up to prevent the metal detector 8 from colliding with the obstacle. When the sonar detects a small obstacle ahead, the lead screw motor 301 in the drive chamber 3 drives the lead screw 302 to rotate. The lead screw 302 rotates relative to the threaded hole 601, thereby causing the lifting rod 6 to slide up within the slide groove 401, preventing the metal detector 8 from colliding with the obstacle. After leaving the obstacle, based on the terrain detection by the sonar component 5, the tow rope 1 is lowered or the lead screw motor 301 drives the lifting rod 6 to descend, maintaining a suitable distance between the metal detector 8 and the underwater detection position, after which underwater metal detection can continue.

[0026] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, various changes or equivalent substitutions can be made without departing from the concept of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
