[0032] refer to Figures 1-4 This embodiment provides a retrievable anchored hydrophone device for use in marine environments, addressing the aforementioned issue of anchor blocks being difficult to retrieve in the prior art. This allows for relatively easy anchoring and recovery of the hydrophone device in marine environments. To further clarify the aforementioned objectives, features, and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] In this embodiment, a recyclable anchored hydrophone device for marine environment is provided. Figure 1 As shown, it includes a floating device 1, a hydrophone device 2 and an anchor block device 3. The floating device 1 is connected to the hydrophone device 2 through a first cable 4, and the hydrophone device 2 is connected to the anchor block device 3 through a second cable 5. Figure 3 As shown, the hydrophone device 2 includes a cage frame 21, a first elastic airbag 22 and a hydrophone 23. A plurality of the first elastic airbags 22 are arranged around the upper half of the cage frame 21, and the hydrophone 23 is arranged on the lower half of the cage frame 21. Figure 4As shown, the anchor block device 3 includes a box body 31, a counterweight block 32 and a rotating shaft 33 arranged in the box body 31, and a plurality of second elastic air bags 35 arranged around the box body 31. Figure 2 As shown, the floating device 1 includes an air inlet and outlet 12 and an elastic air tube 13, and the elastic air tube 13 is connected to the first elastic air bag 22 and the second elastic air bag 35 respectively. After the measurement is completed, the first elastic air bag 22 and the second elastic air bag 35 are inflated through the elastic air tube 13, so that the hydrophone device 2 and the anchor block device 3 float up and are recovered.

[0034] like Figure 4 As shown, the second cable 5 is wound around the rotating shaft 33, and the rotating shaft 33 can release the second cable 5; gears 34 are respectively provided at both ends of the rotating shaft 33, and a bottom plate 36 is provided on the outer side of the bottom of the box body 31, and a steel column 37 is provided on the bottom plate 36. The steel column 37 passes through the bottom of the box body 31 and extends into the box body 31. The bottom plate 36 is connected to the bottom of the box body 31 through a compression spring 38. Two steel columns 37 are provided on the bottom plate 36 corresponding to the gears 34 at both ends of the rotating shaft 33. The positions of the steel columns 37 correspond to the positions of the gears 34. The box body 31 can be pushed and the compression spring 38 can be compressed to move toward the bottom plate 36. The steel column 37 can be inserted into the tooth gap of the gear 34 under the push of the box body 31, so that the release of the second cable 5 by the rotation of the rotating shaft 33 is locked. At this time, the length of the second cable 5 is fixed, and the cable length between the hydrophone device 2 and the anchor block device 3 remains unchanged, so that the hydrophone device 2 is always located in one position.

[0035] In this embodiment, the first cable 4 connects the float device 1 to the hydrophone device 2, allowing it to provide buoyancy support while maintaining a stable relative position between the two, facilitating monitoring by the hydrophone 23 at an appropriate depth. A second cable 5 connects the float device 1 and is wound around a shaft 33. Rotation of the shaft 33 releases the second cable 5, which, combined with the weight of the anchor block device 3, allows the entire device to be stably anchored to the seabed.

[0036] In this embodiment, the locking function for releasing the second cable 5 is achieved through the interaction of the rotating shaft 33, the gear 34, the steel column 37, the compression spring 38, and the counterweight 32. When the anchor block device 3 is lowered to the seabed, it cannot be lowered further. Under the push of the counterweight 32, the box 31 compresses the compression spring 38, causing the steel column 37 to insert into the tooth gap of the gear 34, preventing the rotating shaft 33 from rotating, thereby locking the second cable 5.

[0037] In this embodiment, the buoy device 1 includes a float 11, which includes the air inlet and outlet 12. The inflation port 131 of the elastic air tube 13 is located on the same horizontal line as the air inlet and outlet 12. After the inflation port 131 of the elastic air tube 13 is filled with gas, the first elastic airbag 22 and the second elastic airbag 35 are simultaneously inflated through the elastic air tube 13. By controlling the inflation of the inflation port 131, the first elastic airbag 22 and the second elastic airbag 35 can be inflated, causing their expansion to generate buoyancy, which propels the hydrophone device 2 and the anchor block device 3 upward, driving the entire device to surface from the seabed, facilitating recovery operations by operators.

[0038] In this embodiment, the bottom of the float device 1 is connected to the top of the cage frame 21 through the first cable 4. The first cable 4 is a cable of fixed length, which enables the hydrophone 23 to measure at a fixed depth, so that the distance between the float device 1 and the hydrophone device 2 remains constant, ensuring the stable position of the hydrophone device 2 in the water, which is conducive to improving the accuracy and reliability of the monitoring data of the hydrophone 23.

[0039] In this embodiment, the elastic air tube 13 is arranged on the side of the floating device 1, and a clamp 14 is provided on the side of the floating device 1. The clamp 14 is used to fix the elastic air tube 13 to prevent the elastic air tube 13 from shifting or loosening on the side of the floating device 1, ensuring that the gas can smoothly pass through the elastic air tube 13 to fill the first elastic air bag 22 and the second elastic air bag 35; the air inlet and outlet 12 is arranged at the top of the floating device 1, which is convenient for the operator to inflate or deflate the air inlet and outlet 12 from above.

[0040] like Figure 3 As shown, at least four first elastic airbags 22 are evenly distributed along the circumference of the upper half of the cage frame 21. The hydrophone 23 is secured to the lower half of the cage frame 21 via an annular clamp 24, located in the middle of the lower half of the cage frame 21. This even distribution enables the first elastic airbags 22 to smoothly lift the cage frame 21 for recovery after inflation.

[0041] like Figure 4 As shown, the second elastic airbags 35 are provided on at least two sides of the box body 31, which increases the buoyancy of the anchor block device 3, helps the anchor block device 3 to float to the surface faster when the device is recovered, and improves the recovery efficiency of the device.

[0042] The specific connection structure between the elastic air tube 13 and the first elastic air bag 22 and the second elastic air bag 35 is that the upper half of the cage frame 21 and the box body 31 are respectively provided with a first air pipe 25 and a second air pipe 39, the first air pipe 25 is connected to the first elastic air bag 22, and the second air pipe 39 is connected to the second elastic air bag 35; the first air pipe 25 includes a first air inlet, the second air pipe 39 includes a second air inlet 391, and the elastic air tube 13 includes a first air pipe 132 and a second air pipe 133; the first air inlet is connected to a three-way connector 26, and the other two interfaces of the three-way connector 26 are respectively connected to the first air pipe 132 and the second air pipe 133, the second air inlet 391 is used to connect the second air pipe 133, and the first air pipe 132 is arranged on the side of the floating device 1.

[0043] The first air inlet is provided with a first one-way valve 27, and the second air inlet 391 is provided with a second one-way valve 392. These prevent gas from flowing back after inflation, ensuring that the first elastic airbag 22 and the second elastic airbag 35 can maintain a stable expansion state after inflation, providing stable buoyancy for the device.

[0044] like Figure 4 As shown, the bottom plate 36 includes a groove 361, and the groove 361 is arranged on the side of the bottom plate 36 away from the box body 31. The design of the bottom plate 36 with the groove 361 can reduce the silt adsorption force.

[0045] The working principle of the recyclable anchored hydrophone device 2 in this embodiment is as follows:

[0046] The float 11 of the float device 1 is first inflated to make its buoyancy greater than the gravity of the hydrophone device 2, and the entire device is sunk into the water. Since the length of the first cable 4 between the float device 1 and the hydrophone device 2 is fixed, the hydrophone device 2 will be suspended in the water, and the anchor block device 3 will continue to sink. The internal shaft 33 will continuously release the second cable 5; when the anchor block device 3 reaches the bottom of the water, the box 31 compresses the compression spring 38 under the action of the gravity of the counterweight block 32, causing the steel column 37 to penetrate into the box 31 until it is inserted into the gear The tooth clearance of 34 prevents the gear 34 and the rotating shaft 33 from rotating, and the second cable 5 also stops releasing and keeps a certain length, so that the hydrophone device 2 will always remain in one position to work; when the device finishes working, it only needs to be inflated through the elastic air tube 13 on the side of the floating device 1. The hydrophone device 2 and the anchor block device 3 gradually rise to the surface under the buoyancy of the elastic air bag. The bottom plate 36 with the groove 361 at the bottom of the anchor block can reduce the adsorption force of the silt on the bottom plate 36, thereby reducing the floating time, which is convenient, fast and effective.

[0047] The above is only a preferred specific embodiment of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with this technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the scope of protection of the present invention.
