Description

Technical Field

[0002] When using multi-beam, three-dimensional real-time sonar, synthetic aperture sonar and other equipment for underwater measurement, it is necessary to install transducer probes and inertial navigation antennas on board. The transducer probe is generally inserted from the side of the ship into the water area at the bottom of the ship through a rod, and the inertial navigation antenna is installed on another rod. Since the inertial navigation antenna is expensive, it is generally only installed on board during measurement. During installation, the rod is tied to the railing of the hull with a rope or cable tie to install the inertial navigation antenna.

[0003] When measuring the relative position relationship between the inertial navigation antenna and the transducer probe, this installation method is difficult to measure and has large errors due to the irregular hull and the large randomness of the installation position of the inertial navigation antenna, which affects the system calibration and data accuracy before measurement. The rod of the inertial navigation antenna is not easy to fix on the ship's side railing. If it is not fixed well, the inertial navigation antenna is at risk of falling into the sea, and it is easy to shake, resulting in inaccurate positioning, affecting the measured data quality and increasing the measurement error.

[0031] See also Figure 1-6 A multi-beam inertial navigation antenna installation device includes a rod body 10, a support plate 40 and a support rod 50. The rod body 10 is used to be fixedly installed on the side 71 of a hull 70. The lower end of the rod body 10 is used to install a transducer probe 20. A first flange 11 is provided on the top of the rod body 10. A mounting hole 41 is provided in the middle of the support plate 40. A first fastener 30 is inserted into the mounting hole 41 and then screwed with the first flange 11. At least one support rod 50 is installed on the support plate 40. The top of the support rod 50 is used to install an inertial navigation antenna 60. By detachably installing the support plate 40 above the rod body 10 where the transducer probe is installed, the support plate 40 is positionally welded with the support rod 50, and the inertial navigation antenna 60 is installed on the support rod 50, so that the installation of the inertial navigation antenna is more convenient and more stable. In addition, the relative position of the inertial navigation antenna and the transducer probe can be obtained by simple calculation, which is convenient for system calibration and improves data accuracy.

[0032] Specifically, the rod body 10 is welded to the side 71 of the hull 70, or is installed on the mounting plate of the side 71 through a U-shaped screw. The first fastener 30 can be a hexagon socket screw or a hand screw. In this embodiment, a hand screw is preferably used for easy installation and removal.

[0033] During installation, the support plate 40 is first placed on the first flange 11, and then the mounting hole 41 is aligned with the threaded hole on the first flange 11. After that, the first fastener 30 is inserted into the mounting hole 41 and screwed with the threaded hole on the first flange 11, so that the support plate 40 is installed and fixed. Since there are four holes or six holes on the first flange 11, the installation position of the support plate 40 can be guaranteed each time during installation, and the support rod 50 is fixedly installed on the support plate 40, and the relative position of the inertial navigation antenna 60 and the transducer probe 20 is also easy to determine.

[0034] The connection between the rod body 10 and the transducer probe 20 can be achieved by welding. Figure 1-3 In a preferred embodiment, a second flange 12 is provided at the lower end of the rod body 10 , and the rod body 10 is bolted to the transducer probe 20 via the second flange 12 , so as to facilitate the disassembly and assembly of the transducer probe 20 .

[0035] For further information, see Figure 1 , 3 The rod body 10 is a steel pipe, and the upper and lower ends of the rod body 10 are respectively provided with threading holes 13. The cable 21 of the transducer probe 20 passes through the threading hole 13 at the lower end of the rod body 10 and passes through the threading hole 13 at the upper end of the rod body 10. Through the above structure, the cable 21 of the transducer probe 20 is laid through the rod body 10, making the laying of the cable 21 more convenient.

[0036] See also Figure 4 , 5 Two reinforcing ribs 42 are arranged on the lower side of the support plate 40, and two connecting ribs 43 are arranged between the two reinforcing ribs 42. The two reinforcing ribs 42 and the two connecting ribs 43 together form a limiting space 44, and the mounting hole 41 is located in the limiting space 44. The reinforcing ribs 42 and the connecting ribs 43 arranged on the bottom of the support plate 40 can not only improve the structural strength of the support plate 40, but also the limiting space 44 formed by the surrounding can limit the first flange 11, so that the threaded hole on the first flange 11 can be easily aligned with the mounting hole 41, thereby improving the installation efficiency.

[0037] When in use, pick up the support plate 40 and insert the limiting space 44 into the first flange 11. It is only necessary to swing the position of the support plate 40 and deform it to quickly align the threaded holes on the first flange 11 with the mounting holes 41. For example, the diameter of the first flange 11 is 100 mm, and the length and width of the limiting space 44 are both 100.5 mm. Due to the small gap, it is easy to align, and then the fastener 30 can be screwed in.

[0038] In the first embodiment, see Figure 1 The support rod 50 includes a longitudinal rod 51, the lower end of the longitudinal rod 51 is connected and fixed to the support plate 40, and the upper end of the longitudinal rod 51 is provided with a screw portion 52, and the inertial navigation antenna 60 is screwed on the screw portion 52, which has a simple structure and is easy to install.

[0039] In the second embodiment, see Figure 2 The support rod 50 includes a longitudinal rod 51 and a transverse rod 53. The lower end of the longitudinal rod 51 is connected and fixed to the support plate 40. One end of the transverse rod 53 is connected to the upper end of the longitudinal rod 51, and the other end is installed with a screw part 52 extending upward. The inertial navigation antenna 60 is screwed on the screw part 52. When in use, refer to Figure 6 The inertial navigation antenna 60 is installed on the transverse rod 53, and the transverse rod 53 can also be tied and fixed with the railing 73 on the top clamping plate 72. This structure does not affect the passage of personnel, and the inertial navigation antenna 60 is located on the clamping plate of the hull 70, and there is no fear that the inertial navigation antenna 60 will fall off, and the signal is good. After the transverse rod 53 is tied and fixed with the railing 73, the inertial navigation antenna 60 can be prevented from shaking.

[0040] For further information, see Figure 3 The support rod 50 further includes an L-shaped rod 54. The longitudinal rod 51 and the transverse rod 53 are tubular structures. One end of the L-shaped rod 54 is inserted into the upper end of the longitudinal rod 51, and one end of the transverse rod 53 is inserted into the other end of the L-shaped rod 54. A second fastener 55 is screwed to the outer wall of the upper end of the longitudinal rod 51, and a third fastener 56 is screwed to the outer wall of one end of the transverse rod 53 close to the longitudinal rod 51; the transverse rod 53 and the L-shaped rod 54 can be directional and telescopically adjusted. Through the above structure, the support rod 50 can be telescopic, which is convenient for storage after disassembly.

[0041] The longitudinal rod 51, the transverse rod 53 and the L-shaped rod 54 are square tubes, so that the transverse rod 53 and the L-shaped rod 54 can be directional telescopically adjusted. Of course, the longitudinal rod 51, the transverse rod 53 and the L-shaped rod 54 can also be the structure of the umbrella center rod, which can be directional telescopically arranged by setting grooves. In order to facilitate adjustment, the second fastener 55 and the third fastener 56 are both hand-tightened bolts.

[0042] The working principle or action process of the utility model is as follows:

[0043] When using, see Figure 6Since the rod body 10 is fixedly mounted on the side 71 of the hull 70, and the transducer probe 20 is located below the rod body 10, the position of the transducer probe 20 is set as the origin, then the relative position of the inertial navigation antenna 60 and the transducer probe 20 on the Y axis is the height from the inertial navigation antenna 60 to the transducer probe 20, on the X axis is the distance of the inertial navigation antenna 60 extending along the transverse rod 53, and on the Z axis is the distance between the longitudinal rod 51 and the rod body 10. Compared with the current method of tying the inertial navigation antenna to any position on the railing of the hull by a rope or a cable tie, the present application can fix the position of the inertial navigation antenna 60, or can conveniently measure the relative position between the inertial navigation antenna 60 and the transducer probe 20, which is more convenient to use and more accurate in position.
