Description

Technical Field

[0001] This utility model relates to the technical field of multibeam sonar sounding system equipment, and in particular to a dual-probe adjustable angle mounting bracket for multibeam sonar sounding systems. Background Technology

[0002] Multibeam sonar bathymetry systems are high-performance sonar devices widely used in underwater topographic mapping, hydrological surveying, and other fields. These systems typically require the probe to be mounted inside a fairing and secured to the hull via a flange.

[0003] Currently, the most common installation solutions on the market are single-probe brackets (i.e., one probe is directly connected to one flange) or dual-probe solutions with fixed-angle tilt installation. These solutions have significant drawbacks: (1) The coverage of a single survey is limited, the survey efficiency is low, and multiple voyages are required to complete the survey of a large area of ​​water, which is time-consuming and labor-intensive. (2) In the prior art, the probe orientation is fixed and cannot be flexibly adjusted during the voyage, resulting in blind spots or complex post-processing required for the scanning data of the onboard multibeam echo sounder, which affects the data quality. Utility Model Content

[0004] In view of the above technical problems, this utility model provides a dual-probe adjustable angle mounting bracket for a multi-beam sonar depth sounding system that allows for easy angle adjustment.

[0005] This utility model provides a dual-probe adjustable angle mounting bracket for a multibeam sonar depth sounding system, characterized in that it includes an adapter flange, a sensor mounting plate, a one-to-two flange assembly, an adjustment assembly, and a plug. The lower part of the adapter flange is connected to the sensor mounting plate by bolts, and the lower part of the sensor mounting plate is connected to the one-to-two flange assembly by bolts. Adjustment assemblies are respectively connected to the left and right sides of the one-to-two flange assembly by bolts, and the adjustment assemblies are connected to the plugs.

[0006] The adjusting assembly includes a connecting plate B, a horizontal connecting pipe, and a vertical flange. The upper part of the vertical flange is connected to the horizontal connecting pipe. One end of the horizontal connecting pipe is connected to a plug, and the other end of the horizontal connecting pipe is fixedly provided with the connecting plate B. Multiple outer ring mating holes B are evenly distributed on the surface of the connecting plate B near the outer edge, and multiple inner ring mating holes B are evenly distributed on the surface of the connecting plate B near the center. The multiple outer ring mating holes B and inner ring mating holes B are staggered. The outer ring mating holes B form an outer circle and are located on the outer ring of the connecting plate B, and the inner ring mating holes B form an inner circle and are located on the inner ring of the connecting plate B. A mounting hole is provided on one side of the horizontal connecting pipe.

[0007] The lower side wall of the adapter flange is provided with a through hole A.

[0008] The sensor mounting plate is provided with positioning mounting holes, which are arranged in a cross shape and are used to install a fixed attitude sensor.

[0009] The one-to-two flange assembly includes a cross-shaped flange connector and a connecting plate A. The left and right sides of the cross-shaped flange connector are respectively fixedly connected to the connecting plate A. Multiple mating holes A are evenly distributed on the connecting plate A. The mating holes A are elliptical. A through hole B is provided on one side wall of the upper part of the cross-shaped flange connector.

[0010] The plug is provided with a mating groove.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a dual-probe adjustable angle mounting bracket for a multi-beam sonar depth sounding system. By adding a "crossbeam" to the original flange structure to form a one-to-two flange structure, the original single-point installation is converted into a stable two-point support, providing a physical basis for the simultaneous installation of two multi-beam probes. This utility model realizes the on-site adjustability of the angle of the mounted multi-beam probe through mechanical structure design, thereby directly optimizing the data collection process and reducing blind spots and post-processing requirements.

[0012] Specifically: Adjustable angle design: The adjustment components (including connecting plate A and connecting plate B) allow each probe to rotate independently in the horizontal plane and be fixed at different angle positions by bolts. This allows users to adjust the "angle" of the two probes on-site according to the actual terrain (such as complex seabed topography), expanding the scanning coverage of the single-shot multibeam echo sounder and reducing data blind spots; Data quality improvement: By flexibly adjusting the probe orientation, the scanning strips are more continuous and complete, reducing the complexity of data stitching and thus improving data quality and accuracy. Although the device itself does not directly process data, it indirectly improves the data collection effect of the multibeam echo sounder through hardware optimization; users can rotate the connecting disk B and fix the angle according to measurement needs, thereby optimizing the scanning mode in real time. This avoids software stitching or repeated voyages after the voyage, improving data efficiency from the source.

[0013] By setting up connecting plates A and B, and fixing them by their relative rotation and staggered mating holes, independent and precise angle adjustment of each probe within the horizontal plane from 0° to 360° (or a specific angle range, such as ±30°) is achieved. This allows operators to quickly adjust the "angle" of the two probes on-site according to specific task requirements (such as detecting complex terrain or side-scanning obstacles), optimizing the coverage of the scanning strip and effectively reducing data blind spots; specifically: The mating hole A on the connecting plate A is elliptical (not circular). This design allows the bolt to slide within a certain range of displacement in the hole. When the connecting plate B is rotated, the bolt can move in the elliptical hole, thereby achieving continuous fine adjustment, rather than being limited to a fixed hole position. Staggered Hole Positions: The outer and inner ring mating holes B on the connecting plate B are staggered, providing more combinations of fixing points. Users can achieve discrete angle adjustments (e.g., 40° per fixing point) by selecting different hole alignment methods. Combined with the sliding of the elliptical holes, full-range adjustment can be achieved. For example, if the elliptical holes allow ±20° sliding, each fixing point can cover a 40° range, and 360° coverage can be achieved through 9 hole positions. In actual design work, the multibeam scanning width is a fan shape greater than 40°, and the actual scanning angle of the multibeam echo sounder at each fixed installation point is greater than 40°. This structural design allows for the integration of IMU / attitude sensor mounting positions on the sensor mounting plate via positioning mounting holes. The length of adjustable components can be customized according to the size of different probe models, enhancing the integration of the entire system and its adaptability to different equipment and ship hull installation conditions. It enables flexible installation of single / dual probes, and the probe orientation angle can be adjusted on-site to adapt to various scanning needs, overcoming the shortcomings of the original structure, which had a fixed orientation and was inconvenient to adjust.

[0017] like Figure 1 As shown, this utility model provides a dual-probe adjustable angle mounting bracket for a multibeam sonar depth sounding system. It is characterized by comprising an adapter flange 1, a sensor mounting plate 2, a one-to-two flange assembly 3, an adjustment assembly 4, and a plug 7. The lower part of the adapter flange 1 is bolted to the sensor mounting plate 2, and the lower part of the sensor mounting plate 2 is bolted to the one-to-two flange assembly 3. Adjustment assemblies 4 are bolted to the left and right sides of the one-to-two flange assembly 3, and the adjustment assembly 4 is connected to the plug 7.

[0018] like Figure 4 As shown, the adjusting assembly 4 includes a connecting plate B41, a horizontal connecting pipe 42, and a vertical flange 43. The upper part of the vertical flange 43 is connected to the horizontal connecting pipe 42. One end of the horizontal connecting pipe 42 is connected to a plug 7, and the other end of the horizontal connecting pipe 42 is fixedly provided with the connecting plate B41. Multiple outer ring mating holes B411 are evenly distributed on the surface of the connecting plate B41 near the outer edge, and multiple inner ring mating holes B412 are evenly distributed on the surface of the connecting plate B41 near the center. The multiple outer ring mating holes B411 and inner ring mating holes B412 are staggered. The outer ring mating holes B411 form an outer circle and are located on the outer ring of the connecting plate B41, and the inner ring mating holes B412 form an inner circle and are located on the inner ring of the connecting plate B41. An installation hole 421 is provided on one side of the horizontal connecting pipe 42.

[0019] like Figure 1 As shown, a through hole A11 is provided on one side wall of the lower part of the adapter flange 1.

[0020] The sensor mounting plate 2 is provided with positioning mounting holes 21, which are arranged in a cross shape. The positioning mounting holes 21 are used to install fixed attitude sensors.

[0021] like Figure 2 As shown, the one-to-two flange assembly 3 includes a cross-shaped flange connector 32 and a connecting plate A31. The connecting plate A31 is fixedly connected to the left and right sides of the cross-shaped flange connector 32 respectively.

A through hole B321 is provided on one side wall of the upper part of the cross-shaped flange connector 32.

[0022] like Figure 3 As shown, a docking groove 71 is provided on the plug 7. Example 2

[0023] Dual-probe installation: First, bolt the adapter flange 1 to the flange reserved on the external hull. Then, bolt the adapter flange 1 to the sensor mounting plate 2 (the inertial navigation IMU equipment used in conjunction with the multi-beam sonar) and the one-to-two flange assembly 3.

[0024] The cables for the multibeam sonar (and any cables for the sonic equipment that may be used) are passed through the through hole A11 in the center of the adapter flange 1 from the ship's cabin to the bottom of the split flange structure.

[0025] Connect the adjustment components to the multibeam sonar being used, such as Figure 1 The vertical flange in the adjustment assembly is connected to the multi-beam sonar device A and the multi-beam sonar device B respectively, and the cable is tightly connected to the sonar probe in the multi-beam sonar device (the optional sound velocity measurement device cable is connected to the sound velocity device).

[0026] According to specific underwater measurement needs, the user uses bolts to deflect and fix the connecting plate B of the adjusting component to the connecting plate A of the one-to-two flange component, and records the angle of rotation. Install the nylon arc-shaped plugs and flow guide structures at both ends of the one-to-two flange component.

[0027] Finally, the multi-beam dual-head mounting bracket was launched into the water for underwater measurement of the equipment.

[0028] Disassembly of the bracket: Disassemble the bracket in the reverse order of installation, and be careful not to lose any of the fastening bolts connecting the parts.

[0029] Among them, the dual probes can independently adjust the horizontal angle, significantly expanding the single-scan range and improving survey efficiency; they can flexibly adapt to complex terrain, reduce data blind spots, and improve data quality and integrity; they have a stable structure, are corrosion resistant, and are suitable for marine environments; they reduce repeated voyages and post-data processing workload, saving operating costs and time. Example 3

[0030] Single-probe installation: As described in Example 2, the user can also install only one probe (e.g., only multibeam sonar device A or device B), with the other side sealed with a plug. This mode is suitable for small-area scanning or backup scenarios, while maintaining the balance of the support structure. Example 4

[0031] Dual-probe installation: Supports the installation of two identical probes. As described in Example 2, users can simultaneously install the same type of device (such as two devices A or two devices B) at both ends to expand coverage or achieve redundancy. The bracket's "one-to-two" structure is specifically designed for dual probes, but by configuring plugs, it can also be used with a single probe.

[0032] The overall bracket design allows users to flexibly choose between single-probe or dual-probe modes according to task requirements, and the probe types can be the same or different, enhancing adaptability and practicality.
