Description

Technical Field

[0001] The utility model relates to the technical field of beacon fastening, in particular to a split adjustable unmanned submersible underwater acoustic beacon fixing device. Background Art

[0002] The ocean is rich in resources, and remotely operated vehicles (ROVs) are essential tools for exploring these resources. An ROV typically consists of a surface control system, an umbilical cable, and an underwater system. While navigating underwater, an ROV sends acoustic pulses from a hydroacoustic beacon to the surface control system. The surface control system analyzes the beacon's position in the water to locate and track the ROV.

[0003] An acoustic beacon typically consists of a cylindrical rod with a spherical launcher mounted on top. ROVs have pre-set mounting holes for the beacon, and different sizes of beacons are typically accommodated depending on the task. The beacon is secured to the ROV using a dedicated clamping fixture. Acoustic beacons come in a variety of sizes (including diameters and lengths) depending on the operating frequency. Designing a separate clamping fixture for each beacon is unreasonable and uneconomical. Therefore, a split, adjustable clamping device is needed to accommodate various sizes of beacons. Utility Model Content

[0004] In response to the above problems, the utility model provides a split and adjustable unmanned submersible underwater acoustic beacon fixing device, which can adapt to underwater acoustic beacons of different heights and diameters by adjusting the position of the bottom receiving plate, the middle clamping assembly and the size of the middle clamping cavity, and has good adaptability.

[0005] Specifically, the utility model provides a split adjustable unmanned submersible underwater acoustic beacon fixing device, comprising:

[0006] A bottom receiving plate, used for receiving the lower end surface of the hydroacoustic beacon;

[0007] A top mounting plate having mounting holes thereon for connecting to an unmanned submersible to fix the hydroacoustic beacon on the unmanned submersible. The bottom receiving plate and the top mounting plate are connected by a plurality of connecting rods, and the position of the top mounting plate on the connecting rods is adjustable;

[0008] At least one set of middle clamping assemblies is provided, wherein the middle clamping assemblies are detachably connected to the connecting rod and the position of the middle clamping assemblies on the connecting rod is adjustable;

[0009] The hydroacoustic beacon passes through the top mounting plate and the middle clamping assembly from top to bottom and then rests on the bottom receiving plate.

[0010] Furthermore, each set of the middle clamping assembly includes:

[0011] There are two curved plates symmetrically arranged along the axis, the two curved plates enclose a clamping cavity for clamping the hydroacoustic beacon, and a gap is left between the ends of the two curved plates;

[0012] There are two groups of adjusting members, which are respectively located at two connecting points of the two arc-shaped plates. The adjusting members are used to connect the two arc-shaped plates and adjust the size of the clamping cavity.

[0013] Furthermore, each group of adjusting members includes:

[0014] Two angle irons are symmetrically arranged, and the two angle irons are respectively connected to the U-shaped holes at the ends of the two arc-shaped plates. The position of the angle irons in the U-shaped holes is adjustable, and the two angle irons are connected by bolts so that the size of the clamping cavity between the two arc-shaped plates can be adjusted.

[0015] Furthermore, a sinking platform is provided on the bottom receiving plate, and the sinking platform is used to connect with the lower end surface of the hydroacoustic beacon.

[0016] Furthermore, the connecting rod is a screw rod, and the top mounting plate, the middle clamping assembly and the bottom receiving plate are all fixed on the screw rod by nuts.

[0017] The working principle of this utility model:

[0018] First, select a suitable intermediate clamping assembly according to the diameter of the target hydroacoustic beacon, adjust the position of the angle iron on the two arc plates in the U-shaped hole, so that the diameter of the clamping cavity between the two arc plates is slightly larger than the diameter of the target hydroacoustic beacon, and then adjust the distance between the bottom receiving plate, the intermediate clamping assembly and the top mounting plate according to the height of the hydroacoustic beacon. Then, pass the hydroacoustic beacon through the top mounting plate and the intermediate clamping assembly from top to bottom, and finally clamp it in the sinking platform at the bottom receiving plate. After receiving the lower end face of the hydroacoustic beacon, tighten the nut on the angle iron to clamp the beacon. Finally, install the entire device in the mounting through hole on the ROV to achieve fixed clamping of the hydroacoustic beacon.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The device provided by the present invention has strong adaptability. For underwater acoustic beacons with a small diameter difference, the size of the clamping cavity between the two arc-shaped plates can be slightly adjusted by adjusting the position of the angle iron and then tightening it with bolts. For underwater acoustic beacons with relatively large diameter differences, underwater acoustic beacons with different diameters can be adapted by equipping intermediate arc-shaped plates of different calibers, which is beneficial to improving the efficiency of ROV launching operations.

[0021] (2) The overall device has a simple structure and is easy to process. It can be formed by simply cutting and punching the plate, which is highly economical. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present invention will be further described in detail below through specific implementations in conjunction with the accompanying drawings.

[0028] Example 1

[0029] like Figure 1 As shown, this embodiment provides a split adjustable unmanned submersible underwater acoustic beacon fixing device, which comprises a top mounting plate 1, two sets of middle clamping assemblies 3 and a bottom receiving plate 2 arranged from above. The top mounting plate 1, the middle clamping assembly 3 and the bottom receiving plate 2 are connected by six steel screws 4, and each part is fixed by a nut. By adjusting the position of the nut, the distance between the top mounting plate 1, the middle clamping assembly 3 and the bottom receiving plate 2 can be achieved to adapt to the acoustic beacons 5 of different heights. Four mounting holes 11 are provided on the top mounting plate 1 for installing the entire device in the mounting through-holes on the ROV to complete the installation and fixation of the acoustic beacon. A sink 21 is provided on the bottom receiving plate 2 to support the lower end face of the acoustic beacon 5.

[0030] like Figure 2As shown, each set of middle clamping components 3 includes: two symmetrically arranged arc-shaped plates 31 and four angle irons 32. The arc-shaped plates 31 are fixed to the screw rod 4 by nuts. Both ends of the arc-shaped plates 31 are provided with U-shaped holes. The lower ends of the angle irons 32 are connected to the U-shaped holes by bolts. A certain gap is left between the ends of the two arc-shaped plates 31 to serve as the movable margin of the two arc-shaped plates 31. The position of the angle irons 32 can be slightly adjusted by loosening the bolts. The two angle irons 32 at the connection of the two arc-shaped plates 31 are connected by bolts. By adjusting the position of the angle irons 32 and the bolts between the two angle irons 32, the size of the clamping cavity formed between the two arc-shaped plates 31 can be slightly adjusted. On the one hand, when the hydroacoustic beacon 5 is installed, the clamping cavity can be slightly enlarged to facilitate the hydroacoustic beacon 5 to enter the device. On the other hand, it can also adapt to hydroacoustic beacons 5 with different diameters.

[0031] like Figure 3 As shown, specifically, after the corresponding materials are prepared, first screw nuts into the tail ends of the six screws 4, then insert the six screws 4 into the bottom receiving plate 2, and connect them with the nuts 7. After confirming that the connection is correct, screw the nuts on the upper end of the bottom receiving plate 2 to fix it. Then, according to the diameter of the target hydroacoustic beacon, select a suitable intermediate clamping assembly, and install the eight angle irons 5 on the four curved plates 31 respectively with bolts. Then, screw nuts at a suitable distance above the bottom receiving plate 2 to receive the curved plates 31, and fix the two layers of curved plates 31 and the top mounting plate 1 in the same way. Then connect the relative angle irons 32 with bolts, and ensure that the diameter of the clamping cavity between the two curved plates 31 is slightly larger than the diameter of the target hydroacoustic beacon 5. After the hydroacoustic beacon 5 passes through the top mounting plate 1 and the curved plate 31 from top to bottom, it is stuck in the sink of the bottom receiving plate 2. Thus, the lower end surface of the hydroacoustic beacon 5 is supported. After confirming that the support is stable, tighten the bolts between the two angle irons to clamp the hydroacoustic beacon 5. Finally, after shaking the device upside down to confirm that the device is clamped correctly, the entire device is installed in the mounting hole on the ROV to complete the fixed clamping goal.

[0032] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
