[0032] Reference Figures 1-4 The present embodiment provides a recyclable anchor type hydrophone device for marine environment to solve the problem that the anchor block cannot be recycled in the prior art. In the marine environment, the anchoring and recycling of the hydrophone device can be easily achieved. In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0033] A recyclable anchor type hydrophone device for marine environment in the present embodiment, as shown in Figure 1 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. As shown in Figure 3 The hydrophone device 2 includes a cage frame 21, a first elastic air bag 22 and a hydrophone 23. The upper half of the cage frame 21 is provided with a plurality of first elastic air bags 22 on the side, and the lower half of the cage frame 21 is provided with the hydrophone 23. As shown in Figure 4As shown, the anchor block device 3 includes a box 31, a weight 32 and a rotating shaft 33 arranged in the box 31, and a plurality of second elastic air bags 35 arranged on the side of the box 31. As shown Figure 2 As shown, the float device 1 includes an air inlet 12 and an elastic air pipe 13, which respectively communicates with the first elastic air bag 22 and the second elastic air bag 35. After the measurement is completed, the first elastic air bag 22 and the second elastic air bag 35 are inflated through the elastic air pipe 13, so that the hydrophone device 2 and the anchor block device 3 float up to realize recovery.

[0034] As shown Figure 4 As shown, the second cable 5 is arranged on the rotating shaft 33, and the rotating shaft 33 is released by rotating. The two ends of the rotating shaft 33 are respectively provided with gears 34, the bottom of the box 31 is provided with a bottom plate 36, the bottom plate 36 is provided with steel columns 37, the steel columns 37 pass through the bottom of the box 31 and extend into the box 31. The bottom plate 36 is connected to the bottom of the box 31 by a compression spring 38, the two ends of the steel column 37 correspond to the gears 34 at the two ends of the rotating shaft 33, and the positions of the steel columns 37 correspond to the positions of the gears 34. The box 31 can be pushed and compressed to move towards the bottom plate 36, and the steel columns 37 can be inserted into the tooth gap of the gears 34 under the pushing of the box 31, so that the rotation of the rotating shaft 33 is locked to release the second cable 5. At this time, the length of the second cable 5 is fixed, and the length of the cable between the hydrophone device 2 and the anchor block device 3 remains unchanged, so that the hydrophone device 2 is always located at a position.

[0035] In this embodiment, the first cable 4 is connected to enable the float device 1 to provide buoyancy support for the hydrophone device 2, while keeping the relative position between the two stable, facilitating the hydrophone 23 to monitor at a suitable depth. The second cable 5 is connected, and the second cable 5 is arranged on the rotating shaft 33, and the rotating shaft 33 is released by rotating. The weight of the anchor block device 3 enables the whole device to be stably anchored on the seabed.

[0036] In this embodiment, the rotating shaft 33, the gears 34, the steel columns 37, the compression spring 38 and the weight 32 are cooperated to realize the locking function of releasing the second cable 5. When the anchor block device 3 is lowered to the seabed, the anchor block device 3 cannot continue to be lowered, and the box 31 compresses the compression spring 38 under the pushing of the weight 32, so that the steel columns 37 are inserted into the tooth gap of the gears 34, preventing the rotating shaft 33 from rotating, thereby locking the second cable 5.

[0037] In the embodiment, the floating device 1 comprises a float 11, the float 11 comprises the air inlet and outlet 12, the inflation port 131 of the elastic air pipe 13 is located on the same horizontal line as the air inlet and outlet 12; after the inflation port 131 of the elastic air pipe 13 is filled with gas, the first elastic air bag 22 and the second elastic air bag 35 are simultaneously inflated and expanded through the elastic air pipe 13. By controlling the inflation of the inflation port 131, the inflation of the first elastic air bag 22 and the second elastic air bag 35 can be realized, so that the buoyancy is generated to push the hydrophone device 2 and the anchor block device 3 to float upwards, and the whole device is brought out of the water from the seabed, which is convenient for the operator to carry out the recovery operation.

[0038] In the embodiment, the bottom of the floating device 1 is connected to the top of the cage frame 21 through the first cable 4, the first cable 4 is a fixed length cable, the hydrophone 23 is measured at a fixed depth, the distance between the floating device 1 and the hydrophone device 2 is kept constant, the stable position of the hydrophone device 2 in the water is ensured, and the accuracy and reliability of the monitoring data of the hydrophone 23 are improved.

[0039] In the embodiment, the elastic air pipe 13 is arranged on the side of the floating device 1, the side of the floating device 1 is provided with a clamp 14, the clamp 14 is used to fix the elastic air pipe 13, prevent the elastic air pipe 13 from being displaced or loosened on the side of the floating device 1, and ensure that the gas can be smoothly filled into the first elastic air bag 22 and the second elastic air bag 35 through the elastic air pipe 13; the air inlet and outlet 12 is arranged on 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] As shown in Figure 3 The first elastic air bag 22 is evenly distributed along the upper half of the cage frame 21. The hydrophone 23 is fixed to the lower half of the cage frame 21 through the annular clamp 24, and the hydrophone 23 is located at the middle position of the lower half of the cage frame 21. This uniform distribution can make the first elastic air bag 22 smoothly float the cage frame 21 for recovery after inflation.

[0041] As shown in Figure 4 The box 31 is provided with the second elastic air bag 35 on at least two sides, which increases the buoyancy of the anchor block device 3, helps the anchor block device 3 to float out of the water faster when the recovery 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 merely describes preferred specific embodiments of the present application, but the design concept of the present application is not limited thereto, and any person skilled in the art, within the technical scope disclosed by the present application, can make non-substantial changes to the present application using the concept, and such changes shall not be regarded as departing from the protection scope of the present application.
