Description

Technical Field

[0001] This invention relates to the field of ultrasonic detection equipment technology, specifically to a marine ultrasonic anti-marine biological detection device. Background Technology

[0002] Marine ultrasonic marine organism detection equipment is a device that uses high-frequency sound waves to inhibit the attachment of marine organisms. It is typically installed in critical areas such as propellers, hulls, and seawater pipelines. Its core principle is to emit ultrasonic waves of specific frequencies to interfere with the attachment and growth of larvae of shellfish, algae, and other organisms, thereby reducing the impact of biofouling on ship performance. Specifically, it prevents biofouling on propellers. Barnacles, algae, and other organisms attached to propellers increase drag and reduce propulsion efficiency. Ultrasonic waves can effectively inhibit the attachment of organisms to critical parts such as propeller blades and hubs, keeping the propeller clean and efficient.

[0003] Existing marine ultrasonic anti-fouling equipment is placed in the water. Due to the impact of ocean currents, the equipment shakes in the water, causing the cables or steel ropes to collide or become entangled with the propeller blades. If the steel ropes or cables get caught in the propeller, the blades cannot start directly, requiring personnel to go down and clean them. Furthermore, long-term friction can damage the cable sheath, causing the equipment to lose power or short-circuit. If the ultrasonic transducer is not in the optimal position, the sound field coverage will be uneven, resulting in some propeller areas still being covered by organisms. Frequent shaking affects the stability of ultrasonic wave transmission and reduces the anti-fouling efficiency. Summary of the Invention

[0004] This invention provides a marine ultrasonic marine biological detection device, which solves the problem of the cable and steel rope of the ultrasonic marine biological detection device causing the remaining propeller blades to become entangled due to the shaking of the ultrasonic marine biological detection device. Technical solution

[0005] To achieve stable fixation of the cables and steel ropes of the ultrasonic marine biological detection equipment and to ensure stable operation of the ultrasonic marine biological detection equipment, the present invention achieves this through the following technical solution: A marine ultrasonic marine biological detection equipment includes an ultrasonic detection device. A top net cover is installed on the top surface of the ultrasonic detection device, and a bottom net cover is installed on the bottom surface of the ultrasonic detection device. A cylindrical shell is installed on the bottom surface of the top net cover and the top surface of the bottom net cover together, which reduces the resistance of the ultrasonic detection device in still water or low-speed flow fields, reduces the swaying caused by ocean currents when anchored, and enables the ultrasonic detection device to operate stably. The ultrasonic detection device has a cable installed inside, and a cable protection component is installed on the top surface of the ultrasonic detection device to prevent the cable from shaking and getting tangled on the propeller blade.

[0006] Furthermore, the cable protection assembly includes an electromagnet and a fixed protective sleeve, the fixed protective sleeve being installed on the top surface of the top mesh cover, and the electromagnet being installed inside the top mesh cover.

[0007] Furthermore, the fixed protective sleeve has an internal telescopic cavity, and a magnetic limiting ring is movably installed on the inner wall of the telescopic cavity. An extension sleeve is installed on the top surface of the magnetic limiting ring.

[0008] Furthermore, an electromagnet is installed inside the fixed protective sleeve, and two movable cavities are opened inside the fixed protective sleeve. Each of the two movable cavities is movably fitted with a locking block.

[0009] Furthermore, several connecting springs are evenly distributed and installed on the inner walls of both movable cavities, and each of the connecting springs is fixedly connected to one end surface of the locking block.

[0010] Furthermore, the fixed protective sleeve has four slots 1 inside, and the extension sleeve has two slots 2 inside. The outer surface of the first locking block is in contact with the inner wall of the first slot and the inner wall of the second slot.

[0011] Furthermore, a cap is installed on the top surface of the extension sleeve, an electromagnet is installed inside the cap, a movable cavity is opened inside the cap, and several connecting springs are evenly distributed on the inner wall of the movable cavity.

[0012] Furthermore, a locking block 2 is fixedly installed on one end surface of several of the connecting springs 2, the outer surface of the locking block 2 is in movable contact with the inner wall of the movable cavity 2, and a rubber extrusion head is installed on one end surface of the locking block 2, the outer surface of the rubber extrusion head is in movable contact with the outer surface of the cable.

[0013] Furthermore, two rope loops are installed on the top surface of the top net cover, two rope loops are installed on the outer surface of the fixed protective sleeve, and two rope loops are installed on the outer surface of the cap. Steel ropes are installed on the two rope loops, and the outer surface of the steel ropes is in contact with the inner surface of the rope loops and the inner surface of the rope loops. Beneficial effects

[0014] The present invention has the following beneficial effects: The ship's ultrasonic marine biological detection equipment uses a cylindrical shell with a streamlined profile to smoothly disperse ocean current impacts, avoid generating turbulent eddies, and significantly reduce the swaying of the ultrasonic detection device. In addition, the cylindrical shell is filled with damping silicone to absorb low-frequency vibrations transmitted by mooring cables, preventing the ultrasonic detection device from swaying near the propeller blades and thus preventing damage to the ultrasonic detection device.

[0015] The ship uses ultrasonic marine biological detection equipment. By using a second locking block to drive a rubber compression head to compress and fix the cable rope, the cable rope remains stable in the water. Simultaneously, the extension sleeve moves the cap, which in turn moves the rope loop three upwards. Rope loop one, rope loop two, and rope loop three thus limit the steel rope. The extension sleeve and the fixed protective sleeve form a fully enclosed metal cavity, physically blocking any contact path between the cable rope and the propeller blade. Even if the steel rope breaks, the magnetic attraction of electromagnets two and three will prevent the steel rope near the propeller blade from getting tangled on the propeller blade, keeping the ultrasonic detection device stable on the outside of the propeller blade and preventing organisms from attaching to the propeller blade.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0019] Please see Figures 1-5 This invention provides a technical solution: a marine ultrasonic anti-marine biological detection device, including an ultrasonic detection device 1, a top net cover 2 installed on the top surface of the ultrasonic detection device 1, a bottom net cover 4 installed on the bottom surface of the ultrasonic detection device 1, and a cylindrical shell 3 installed on the bottom surface of the top net cover 2 and the top surface of the bottom net cover 4, so as to reduce the resistance of the ultrasonic detection device 1 in still water or low-speed flow field, reduce the swaying caused by ocean current when anchored, and enable the ultrasonic detection device 1 to work stably. The ultrasonic detection device 1 has a cable 26 installed inside. A cable protection component is installed on the top surface of the ultrasonic detection device 1. The cable protection component prevents the cable 26 from shaking and from getting tangled on the propeller blade. The streamlined profile of the cylindrical shell 3 can smoothly disperse the impact of ocean currents and avoid generating turbulent vortices, significantly reducing the shaking of the ultrasonic detection device 1. In addition, the cylindrical shell 3 is filled with damping silicone to absorb the low-frequency vibration transmitted by the mooring cable, preventing the ultrasonic detection device 1 from shaking near the propeller blade, thereby preventing damage to the ultrasonic detection device 1.

[0020] The cable protection assembly includes an electromagnet 5 and a fixed protective sleeve 6. The fixed protective sleeve 6 is installed on the top surface of the top mesh cover 2. The electromagnet 5 is installed inside the top mesh cover 2. The fixed protective sleeve 6 has a telescopic cavity 7 inside. A magnetic limiting ring 8 is movably installed on the inner wall of the telescopic cavity 7. An extension sleeve 9 is installed on the top surface of the magnetic limiting ring 8. The controller controls the electromagnet 5 to be energized. The corresponding surfaces of the electromagnet 5 and the magnetic limiting ring 8 have the same magnetism. The electromagnet 5 and the magnetic limiting ring 8 directly generate a repulsive force, thereby causing the magnetic limiting ring 8 to drive the extension sleeve 9 to move within the telescopic cavity 7.

[0021] An electromagnet 2 10 is installed inside the fixed protective sleeve 6. The fixed protective sleeve 6 has two movable cavities 1 11. A locking block 12 is movably installed on the inner wall of each of the two movable cavities 1 11. Several connecting springs 14 are evenly distributed on the inner wall of each of the two movable cavities, and each connecting spring 14 is fixedly connected to one end surface of a locking block 12. The fixed protective sleeve 6 has four locking slots 1 13 inside, and the extension sleeve 9 has two locking slots 2 15 inside. The outer surface of the locking block 1 12 is connected to the inner wall of the locking slot 13 and the locking slot... The inner wall of the second 15 is in active contact. The controller controls the second 10 to work. The electromagnet second 10 and the magnetic limiting ring 8 have opposite magnetic properties, so that the magnetic limiting ring 8 is reinforced in the telescopic cavity 7. The first 12 of the locking block is made of iron element material, so that the first 12 of the locking block moves in the first 11 of the movable cavity, so that the first 12 of the locking block stretches the first 14 of the connecting spring in the first 11 of the movable cavity, so that the first 12 of the locking block passes through the first 13 of the locking groove, the second 15 of the locking groove, and the first 13 of the locking groove in sequence, so that the extension sleeve 9 is fixed in the telescopic cavity 7.

[0022] A cap 16 is mounted on the top surface of the extension sleeve 9. An electromagnet 3 17 is installed inside the cap 16. A movable cavity 2 18 is opened inside the cap 16. Several connecting springs 2 19 are evenly distributed and installed on the inner wall of the movable cavity 2 18. A locking block 20 is fixedly installed on one end surface of the connecting springs 2 19. The outer surface of the locking block 20 is in movable contact with the inner wall of the movable cavity 2 18. A rubber extrusion head 21 is installed on one end surface of the locking block 20. The outer surface of the rubber extrusion head 21 is in contact with the outer surface of the cable 26. The active contact allows the extension sleeve 9 and the fixed protective sleeve 6 to limit and protect the cable 26 of the propeller blade accessory. The controller controls the electromagnet 3 17 to be energized, making the electromagnet 3 17 magnetic. The locking block 20 is made of iron element material, so that the locking block 20 can move in the movable cavity 2 18, thereby compressing the connecting spring 2 19 in the movable cavity 2 18. The locking block 20 drives the rubber extrusion head 21 to compress and fix the cable rope, so that the cable rope remains stable in the water.

[0023] Two rope loops 22 are installed on the top surface of the top cover 2, two rope loops 23 are installed on the outer surface of the fixed protective sleeve 6, and two rope loops 24 are installed on the outer surface of the cap 16. Steel ropes 25 are installed on the two rope loops 22 respectively. The outer surface of the steel rope 25 is in contact with the inner surface of the rope loops 23 and 24. The rope loops 22, 23 and 24 limit the steel rope 25. The extension sleeve 9 and the fixed protective sleeve 6 form a fully enclosed metal cavity, which physically blocks any contact path between the cable and the propeller blade. Even if the steel rope 25 breaks, the magnetic attraction of the electromagnets 10 and 17 will prevent the steel rope 25 near the propeller blade from getting tangled on the propeller blade, so that the ultrasonic detection device 1 is stabilized on the outside of the propeller blade and prevents organisms from attaching to the propeller blade.

[0024] The specific working process of this invention is as follows: When the ship stops moving, the top net cover 2 and the bottom net cover 4 are welded to the top and bottom surfaces of the ultrasonic detection device 1, respectively. The cylindrical shell 3 is fixed between the top net cover 2 and the bottom net cover 4 by bolts, so that the ultrasonic detection device 1 can descend stably. The streamlined contour of the cylindrical shell 3 can smoothly disperse the impact of ocean currents, avoid the generation of turbulent vortices, and significantly reduce the shaking of the ultrasonic detection device 1. In addition, the cylindrical shell 3 is filled with damping silicone to absorb the low-frequency vibration transmitted by the mooring cable, preventing the ultrasonic detection device 1 from shaking near the propeller blade, thereby preventing damage to the ultrasonic detection device 1.

[0025] Furthermore, the controller controls electromagnet 5 to be energized. Electromagnet 5 and the corresponding surface of the magnetic limiting ring 8 have the same magnetism, directly generating a repulsive force. This causes the magnetic limiting ring 8 to move the extension sleeve 9 within the telescopic cavity 7. The controller then controls electromagnet 10 to operate. Electromagnet 10 and the corresponding surface of the magnetic limiting ring 8 have opposite magnetism, reinforcing the magnetic limiting ring 8 within the telescopic cavity 7. The locking block 12, made of ferrous material, moves within the movable cavity 11, stretching the connecting spring 14. The locking block 12 then passes sequentially through slots 13, 15, and 13, fixing the extension sleeve 9 within the telescopic cavity 7. This, along with the fixed protective sleeve 6, provides limiting protection for the propeller blade accessory cable 26. The controller also controls electromagnet 317. The electromagnet 17 is magnetized by being connected to the power source. The locking block 20 is made of iron, allowing it to move within the movable cavity 18. This causes the locking block 20 to compress the connecting spring 19 within the movable cavity 18, which in turn causes the locking block 20 to drive the rubber extrusion head 21 to compress and fix the cable rope, keeping it stable in the water. Simultaneously, the extension sleeve 9 moves the cap 16, which in turn moves the rope ring 24 upward. The rope rings 22, 23, and 24 limit the movement of the steel rope 25. The extension sleeve 9 and the fixed protective sleeve 6 form a fully enclosed metal cavity, physically blocking any contact path between the cable and the propeller blade. Even if the steel rope 25 breaks, the magnetic attraction of the electromagnets 10 and 17 prevents the steel rope 25 near the propeller blade from getting tangled on it, keeping the ultrasonic detection device 1 stable on the outside of the propeller blade and preventing organisms from attaching to it.
