Description

Technical Field

[0001] This utility model relates to the field of marine environmental monitoring technology, specifically a buoy-type integrated acoustic and electromagnetic detection device. Background Technology

[0002] Buoy-type detection devices are commonly used in fields such as marine environmental monitoring and underwater target detection. Traditional detection buoys have relatively limited functions, typically only detecting single physical fields such as acoustics or electromagnetics, which makes it difficult to meet the needs of simultaneously acquiring information from multiple physical fields in complex environments.

[0003] Many existing buoys are fixed in place and remain floating on the surface of the water during use, making it difficult for detection devices to probe waters at different depths.

[0004] To address the aforementioned problems, we propose a buoy-type integrated acoustic-electromagnetic detection device. Utility Model Content

[0005] To address the problems in the background technology, this utility model provides a buoy-type integrated acoustic and electromagnetic detection device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A buoy-type integrated acoustic and electromagnetic detection device includes a buoy body, an acoustic and electromagnetic detection module disposed on the bottom surface of the buoy body, the acoustic and electromagnetic detection module being installed in a ring-shaped arrangement, a floating assembly including an air bladder fixedly installed around the upper side of the buoy body, a high-pressure inflation cylinder disposed in the middle of the inner cavity of the buoy body for inflating the air bladder, and a positioning assembly including a fixed anchor located at the bottom of the buoy body, a steel wire rope connected to the middle of the upper end of the fixed anchor, the steel wire rope being wound and unwound by a winding assembly.

[0007] Preferably, a hoisting box is provided at the bottom center of the buoy body, and the winding assembly is located at the inner center of the hoisting box. The winding assembly includes a support frame, and a winding wheel is provided at the upper center of the support frame. The winding wheel is driven by a motor, and the head end of the wire rope is wound around the winding wheel. The motor drives the winding wheel to rotate, thereby performing the winding and unwinding movement of the wire rope.

[0008] Preferably, a sealing cap is provided at the upper middle part of the buoy body, and an air outlet pipe is provided at the upper middle part of the sealing cap, which is connected to the air outlet end of the airbag.

[0009] Preferably, an inflation tube is provided on the upper right side of the sealing cap, and the inflation tube is connected to the inflation end of the high-pressure gas cylinder.

[0010] Preferably, the bottom of the hoisting box is provided with a counterweight, which is hemispherical.

[0011] Preferably, a channel is provided in the middle of the inner side of the counterweight, and the steel wire rope passes through the channel.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This solution integrates acoustic and electromagnetic detection modules and adopts a ring-shaped distribution method, which enables synchronous and multi-angle detection of acoustic and electromagnetic field information of the underwater environment, significantly improving the comprehensiveness and accuracy of the detection data. Through the setting of floating and positioning components, combined with the fixed anchor at the bottom, the buoy can be reliably moored in the designated water area to prevent it from drifting with the waves, thus ensuring the reliability of long-term, fixed-point detection. In addition, by flexibly inflating and deflating the airbag, and simultaneously using a reel to wind up and unwind the steel wire rope, the height of the buoy body and the acoustic-electromagnetic detection module in the water can be adjusted. This allows the acoustic-electromagnetic detection module to sink to different depths of water for detection, making the detection work more comprehensive and accurate. Attached Figure Description

[0015] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: Example: Refer to Figure 1 - Figure 2 As shown, this embodiment of a buoy-type integrated acoustic and electromagnetic detection device includes a buoy body 1, and an acoustic and electromagnetic detection module 2 is provided on the bottom surface of the buoy body 1. The electronic control system of the acoustic and electromagnetic detection module 2 adopts existing mature technology. The acoustic and electromagnetic detection module 2 is installed in a ring distribution and is used to simultaneously collect underwater acoustic and electromagnetic signals. It can realize synchronous and multi-angle detection of acoustic and electromagnetic field information of underwater environment, which significantly improves the comprehensiveness and accuracy of detection data.

[0016] The floating assembly includes an airbag 3, which is fixedly installed on the upper side of the buoy body 1. A high-pressure inflation bottle 4 is provided in the middle of the inner cavity of the buoy body 1. The high-pressure inflation bottle 4 is used to inflate the airbag 3. The positioning assembly includes a fixed anchor 13, which is located at the bottom of the buoy body 1. A steel wire rope 12 is connected to the middle of the upper end of the fixed anchor 13. The steel wire rope 12 is wound up and unwound by a winding assembly.

[0017] Furthermore, a lifting box 8 is provided at the bottom center of the buoy body 1, and a winding assembly is provided at the inner center of the lifting box 8. The winding assembly includes a support frame 9, and a winding wheel 10 is provided at the upper center of the support frame 9. The winding wheel 10 is driven by a motor 11, and the head end of the wire rope 12 is wound around the winding wheel 10. The motor 11 drives the winding wheel 10 to rotate, thereby performing the winding and unwinding movement of the wire rope 12. During operation, the device is deployed in the target water area. The air bladder 3 is inflated using the high-pressure air cylinder 4, allowing the buoy to float stably. The acoustic-electromagnetic detection module 2 is then activated to collect data. Simultaneously, the steel cable sling 12 is released via the motor 11, causing the fixed anchor 13 to sink to the bottom, achieving precise buoy positioning and preventing the buoy body 1 from drifting with the water flow. After the detection is completed, the fixed anchor 13 can be retrieved via the motor 11 for easy buoy recovery.

[0018] In some examples, a sealing cover 5 is provided at the upper middle part of the buoy body 1, and an air outlet pipe 6 is provided at the upper middle part of the sealing cover 5. The air outlet pipe 6 is connected to the air outlet end of the airbag 3 and is used to release the gas inside the airbag 3.

[0019] In some examples, an inflation tube 7 is provided on the upper right side of the sealing cap 5. The inflation tube 7 is connected to the inflation end of the high-pressure gas cylinder 4, and the inflation tube 7 facilitates the staff to inflate the high-pressure gas cylinder 4.

[0020] In some examples, the bottom of the lifting box 8 is provided with a counterweight 14, which is hemispherical to enhance the counterweight effect.

[0021] In some examples, a channel 15 is provided in the middle of the inner side of the counterweight 14, through which the wire rope 12 passes.

[0022] The working principle of this utility model is as follows: This utility model integrates an acoustic and electromagnetic detection module 2 and adopts a ring distribution method, which can realize synchronous and multi-angle detection of acoustic and electromagnetic field information of underwater environment, significantly improving the comprehensiveness and accuracy of detection data. In addition, during use, by flexibly inflating and deflating the airbag 3, and simultaneously using the reel 10 to reel in and unwind the steel wire rope 12, the height of the buoy body 1 and the acoustic electromagnetic detection module 2 in the water can be adjusted, allowing the acoustic electromagnetic detection module 2 to perform detection work in waters of different depths, making the detection work more comprehensive and accurate. The specific adjustment steps are as follows: When it is necessary to sink the buoy body 1, first open the exhaust valve of the airbag 3, and the gas will be discharged outward through the air outlet pipe 6. At this time, the buoyancy decreases, and the buoy body 1 will sink under its own weight. At the same time, the motor 11 drives the winding wheel 10 to wind up the steel wire rope 12. When the fixed anchor 13 is in a fixed state, a downward pulling force is formed on the buoy body 1 to assist the buoy body 1 in sinking and enhance the stability of sinking. The buoy body 1 can be sinked in multiple stages by exhausting the airbag 3 in multiple stages, thereby realizing multi-stage detection work. Finally, after the detection work is completed, the reel 10 begins to release the line. At the same time, the air outlet pipe 6 is closed, and the high-pressure air cylinder 4 is activated to inflate the airbag 3 in a balanced manner, thereby increasing the buoyancy generated by the airbag 3. As the buoyancy increases, it is released to release the restraints, and the buoy body 1 will rise back to the water surface and float.
