Description

Technical Field

[0001] This invention relates to the field of sonar probe installation technology, and in particular to a multibeam sonar probe installation device and its installation method. Background Technology

[0002] Marine surveys and seabed exploration are fundamental to marine management, engineering design, maritime delimitation, resource development, national defense, and marine scientific research. Shipborne underway surveys are the most basic method of marine surveying, providing a wealth of data for marine scientific research and engineering. Proper installation of marine survey instruments is a strong guarantee for obtaining effective survey data. Seabed topography and geomorphology surveys, as an important part of marine hydrography, are a fundamental aspect of marine surveying. To reveal useful information such as seabed elevation variations and substrate types, high-resolution multibeam bathymetry is an indispensable survey method.

[0003] Currently, ship-based seabed topography surveys are conducted using two methods: towed and shipborne. Towed survey instruments mainly include side-scan sonar and shallow-water profilers. These devices do not require precise depth measurements, and their installation requirements are relatively low. Shipborne instruments are mostly used for single-beam bathymetry, multi-beam bathymetry, and coherent sonar bathymetry, which are designed for precise depth measurements. A significant characteristic of shipborne instruments is their requirement for real-time attitude measurement, making their installation accuracy requirements much higher than those of towed instruments. The installation methods for shipborne survey instruments can be categorized as fixed installation on the ship's hull, installation in a survey well, and portable installation on the ship's hull. Survey well installation involves creating a vertical shaft at the stern of the survey vessel and fixing the scientific instruments within it. However, multi-beam sonar probes installed in this method have a fixed detection direction, making adjustment inconvenient and limiting their detection capabilities. Therefore, this paper proposes a multi-beam sonar probe installation device and its installation method. Summary of the Invention

[0004] Based on the technical problems existing in the background technology, the present invention proposes a multibeam sonar probe installation device and its installation method.

[0005] The present invention proposes a multibeam sonar probe mounting device, including a mounting cylinder, a mounting column that can move up and down is provided inside the mounting cylinder, an electrical mounting cylinder is rotatably provided at the lower end of the mounting column, an adjustment component for adjusting the angle of the electrical mounting cylinder is provided inside the mounting column, and a lifting component for adjusting the height of the mounting column is provided inside the mounting cylinder.

[0006] The electrical mounting cylinder includes a cylindrical part, one end of which is open, and a transparent protective cover is fixed to the open end of the cylindrical part. An adjusting block is provided at the end of the electrical mounting cylinder away from the transparent protective cover. A second rotating hole is provided on the adjusting block. The outer diameter of the cylindrical part is the same as the outer diameter of the mounting column. The central axis of the second rotating hole intersects with the central axis of the cylindrical part.

[0007] The mounting post has a rectangular notch at its lower part, and a first rotating pin is provided on the lower inner side of the rectangular notch. The first rotating pin is rotatably connected to a second rotating hole. A circular channel is coaxially provided on the mounting post, and a sliding sleeve is slidably disposed in the circular channel. A hinge seat is provided at the lower end of the sliding sleeve, and a connecting rod is hinged in the hinge seat. The adjusting block is provided with a hinge groove adapted to the connecting rod. A first rotating hole is provided at the end of the adjusting block away from the cylindrical part, and the first rotating hole is connected to the hinge groove. A second rotating pin is rotatably disposed in the first rotating hole, and the lower end of the connecting rod is fixedly connected to the second rotating pin. A power component is provided on the upper part of the mounting post to realize the sliding sleeve moving up and down along the circular channel.

[0008] The multibeam sonar probe is installed inside the cylindrical section. The sliding sleeve is moved down by the power component, and in conjunction with the connecting rod, the adjusting block is rotated, thereby changing the orientation of the electrical mounting cylinder. This can change the detection direction of the multibeam sonar probe. At the same time, the lifting component can be controlled to adjust the height of the electrical mounting cylinder to meet different detection needs.

[0009] As a further optimization of this technical solution, the present invention provides a multi-beam sonar probe mounting device. A movable sleeve is fitted around the outer side of the mounting post, and an annular limiting ring is provided at the upper end of the movable sleeve. A linkage component is provided inside the mounting post, which, as the movable sleeve moves, slides on the surface of the mounting post. A second strip-shaped groove is provided on one side of the mounting post, connecting to a circular channel. The sidewall of the second strip-shaped groove is parallel to the sidewall of the rectangular notch. Second strip-shaped slideways extending along the length of the mounting post are provided on the inner walls of both sides of the second strip-shaped groove. The linkage component includes the same movable strip slidably disposed within two of the second strip-shaped slideways. A second rack is provided on the side away from the sliding sleeve. Both ends of the movable strip near the sliding sleeve are provided with protrusions. A metal rod is fixed between the two protrusions. The sliding sleeve near the movable strip has a planar structure, and an ear block is provided at the lower part of the sliding sleeve near the movable strip. The ear block has a through hole, through which the metal rod passes. A first rack is provided on the inner wall of one side of the movable sleeve along its length. A rotating shaft is provided at the lower part of the inner side of the second strip groove, and a gear is rotatably provided on the rotating shaft. The gear meshes with the first rack and the second rack. Springs are sleeved on the outer circumference of the metal rod near the upper and lower parts of the ear block.

[0010] In this preferred embodiment, when the sliding sleeve moves downward under the action of the power component, the set lug drives the movable bar and the second rack to move together. The second rack drives the gear meshing with it to rotate, thereby driving the first rack and the movable sleeve to move upward, which can ensure that the adjusting block can rotate. When the control power component drives the sliding sleeve to move upward, in conjunction with the linkage, the adjusting block is finally adjusted to a vertical state. During this process, as the sliding sleeve moves upward, it drives the movable bar and the second rack to move upward, and in conjunction with the gear, it drives the first rack and the movable sleeve to move downward, finally fitting the movable sleeve onto the outside of the cylindrical part, thereby improving the stability of the electrical mounting cylinder and adjusting the multi-beam sonar probe to a vertical working state.

[0011] As a further optimization of this technical solution, the present invention provides a multi-beam sonar probe mounting device, wherein a circular disk is fixed on the top of the mounting column, and the power assembly includes a first motor fixed at the middle position of the top of the circular disk. The output shaft of the first motor passes through the circular disk and is fixed with a first lead screw. The first lead screw is inserted into a sliding sleeve, and a first lead screw nut is fixed on the top of the sliding sleeve. The first lead screw passes through the first lead screw nut, and the first lead screw and the first lead screw nut form a threaded engagement.

[0012] As a further optimization of this technical solution, the present invention provides a multi-beam sonar probe mounting device. The mounting cylinder includes a vertical cylinder, a mounting flange is provided at the top of the vertical cylinder, an annular mounting groove is coaxially provided on the upper part of the mounting flange, and a top cover is fixed in the annular mounting groove. The lower end of the vertical cylinder is provided with an upwardly recessed conical cover, and an annular portion is coaxially provided on the upper part of the conical cover. The outer diameter of the mounting column is adapted to the inner diameter of the annular portion. An annular sealing groove is provided at the lower part of the outer circumferential surface of the vertical cylinder, and a sealing rubber ring is provided in the annular sealing groove.

[0013] As a further optimization of this technical solution, the present invention provides a multi-beam sonar probe mounting device, wherein an annular retaining ring is provided on the outer peripheral surface of the cylindrical part near the end of the adjusting block.

[0014] In this preferred embodiment, the annular retaining ring can limit the movement of the movable sleeve, preventing it from moving further downward.

[0015] As a further optimization of this technical solution, the present invention provides a multi-beam sonar probe mounting device. The lifting assembly includes an annular mounting frame fixed at the upper part of the inner side of the mounting cylinder. A second motor is fixed on one side of the upper part of the annular mounting frame. The output shaft of the second motor passes through the annular mounting frame and is fixed with a second lead screw. A mounting hole is provided on one side of the top of the circular disk, and a second lead screw nut is fixed in the mounting hole. The second lead screw passes through the second lead screw nut, and the second lead screw and the second lead screw nut form a threaded engagement.

[0016] As a further optimization of this technical solution, the present invention provides a multi-beam sonar probe mounting device, wherein a vertically arranged optical axis sliding sleeve is fixedly installed on the side of the circular disk away from the second lead screw, the optical axis sliding sleeve passes through the circular disk, an optical axis is inserted inside the optical axis sliding sleeve, and the top end of the optical axis is fixedly connected to an annular mounting frame.

[0017] In this preferred embodiment, the optical axis and the optical axis sleeve serve as guides, which helps to improve the stability of the mounting column during its up-and-down movement. The second motor drives the second lead screw to rotate, which, in conjunction with the second lead screw nut, drives the circular disc to move up and down, thereby causing the mounting column to move up and down inside the mounting cylinder, which can adjust the height of the electrical mounting cylinder.

[0018] As a further optimization of this technical solution, the present invention provides a multi-beam sonar probe mounting device, wherein a connecting rod is rotatably mounted on the inner side of the rectangular notch near the second strip groove, an elastic folding plate is fixed on the connecting rod, the elastic folding plate has an L-shaped structure, a sliding pin is fixed at the lower end of the elastic folding plate, a first strip groove is provided on both sides of the rectangular notch, and the two ends of the sliding pin are respectively slidably mounted in the two first strip grooves, and a bent part is provided on the end of the connecting rod near the adjusting block.

[0019] In this preferred embodiment, the elastic folding plate can push the adjusting block towards one side of the first groove, and in conjunction with the bending part, it helps the adjusting block to rotate smoothly towards the first groove side during the downward movement of the sliding sleeve.

[0020] As a further optimization of this technical solution, the present invention provides a multi-beam sonar probe mounting device, wherein the mounting post has a first strip groove with a connecting rectangular notch at its lower part on the side away from the second strip groove, and the width of the first strip groove is greater than the thickness of the connecting rod.

[0021] In this preferred embodiment, during the downward movement of the sliding sleeve, the connecting rod tilts and falls into the first slot. The first slot ensures the moving space of the connecting rod.

[0022] A method for installing a multibeam sonar probe mounting device includes the following steps:

[0024] S2; Hull preparation: A circular hole adapted to the mounting cylinder is opened in the middle or bow of the hull, and an inner liner is welded into the circular hole to ensure that the mounting cylinder can be inserted into the inner liner.

[0025] S3: Device installation: Insert the mounting cylinder into the circular hole from the top of the hull, and ensure that the sealing ring fits precisely with the inner liner to achieve a seal. Then, fix the mounting cylinder onto the hull using the mounting flange.

[0026] S4: Device testing. Remove the top cover, connect the lifting assembly and power assembly to power, control the first motor to work, drive the first lead screw to rotate, and cooperate with the first lead screw nut to realize the rise and fall of the sliding sleeve. This, in conjunction with the connecting rod, adjusts the angle of the electrical mounting cylinder. With the cooperation of the linkage assembly, as the sliding sleeve moves up, the movable sleeve moves down, and as the sliding sleeve moves down, the movable sleeve moves up. By controlling the second motor to work, and cooperating with the second lead screw and the second lead screw nut, the mounting column can be moved up or down inside the mounting cylinder to change the height of the electrical mounting cylinder. The multi-beam sonar probe is then connected to the sonar detection terminal for detection testing.

[0027] In summary, the beneficial effects of this invention are as follows:

[0028] The adjustable components allow for adjustment of the electrical mounting cylinder's angle, thus meeting the detection needs of multi-beam sonar probes at different angles. Simultaneously, the lifting components allow for adjustment of the electrical mounting cylinder's depth to meet detection needs at varying depths. Furthermore, the movable sleeve, in conjunction with the adjustable components, can be fitted onto the outside of the electrical mounting cylinder in a vertical position, enhancing its stability.

[0045] The multibeam sonar probe is installed inside the cylindrical part 302. The sliding sleeve 403 is moved down by the power component. In conjunction with the connecting rod 404, the adjusting block 301 is rotated, thereby changing the orientation of the electrical mounting cylinder 3. This can change the detection direction of the multibeam sonar probe. At the same time, the lifting component 7 is controlled to work, which can adjust the height of the electrical mounting cylinder 3 to meet different detection needs.

[0050] See attached document Figure 2 An annular sealing groove is provided at the lower part of the outer peripheral surface of the vertical cylinder 101, and a sealing ring 102 is provided inside the annular sealing groove.

[0051] See attached document Figure 4 An annular retaining ring is provided on the outer peripheral surface of the cylindrical part 302 near the end of the adjusting block 301. The annular retaining ring can limit the movable sleeve 5 and prevent the movable sleeve 5 from moving further down.

[0052] See attached document Figure 5 and attached Figure 11 The lifting assembly 7 includes an annular mounting bracket 701 fixed at the upper part of the inner side of the mounting cylinder 1. A second motor 702 is fixed on one side of the upper part of the annular mounting bracket 701. The output shaft of the second motor 702 passes through the annular mounting bracket 701 and is fixed with a second lead screw 703. A mounting hole is provided on one side of the top of the circular disc 206, and a second lead screw nut 2062 is fixed in the mounting hole. The second lead screw 703 passes through the second lead screw nut 2062, and the second lead screw 703 and the second lead screw nut 2062 form a threaded engagement.

[0053] See attached document Figure 11A vertically arranged optical axis sleeve 2061 is fixedly installed on the side of the circular disk 206 away from the second lead screw 703. The optical axis sleeve 2061 passes through the circular disk 206, and an optical axis 704 is inserted inside the optical axis sleeve 2061. The top end of the optical axis 704 is fixedly connected to the annular mounting bracket 701. The optical axis 704 and the optical axis sleeve 2061 play a guiding role, which helps to improve the stability of the mounting column 2 during the up and down movement. When the second motor 702 works, it drives the second lead screw 703 to rotate. With the cooperation of the second lead screw nut 2062, it drives the circular disk 206 to move up and down, thereby driving the mounting column 2 to move up and down inside the mounting cylinder 1. The height of the electrical mounting cylinder 3 can be adjusted.

[0054] See attached document Figure 6 and attached Figure 10 A connecting rod 2011 is rotatably mounted on the inner side of the rectangular notch 201 near the second strip groove 204. An elastic folding plate 6 is fixed on the connecting rod 2011. The elastic folding plate 6 has an L-shaped structure. A sliding pin 601 is fixed at the lower end of the elastic folding plate 6. First strip tracks 2012 are provided on both sides of the rectangular notch 201, and the two ends of the sliding pin 601 are slidably mounted in the two first strip tracks 2012 respectively. A bending part 4041 is provided on the end of the connecting rod 404 near the adjusting block 301. With the elastic folding plate 6 in place, the adjusting block 301 can be pushed towards the first strip groove 202. In conjunction with the bending part 4041, it helps the adjusting block 301 to rotate smoothly towards the first strip groove 202 during the downward movement of the sliding sleeve 403.

[0055] The mounting post 2 has a first strip groove 202 on the lower part of the side away from the second strip groove 204, which is connected to the rectangular notch 201. The width of the first strip groove 202 is greater than the thickness of the connecting rod 404. During the downward movement of the sliding sleeve 403, the connecting rod 404 is pushed to tilt, and the connecting rod 404 will fall into the first strip groove 202. The setting of the first strip groove 202 ensures the movement space of the connecting rod 404.

[0056] In this embodiment, when the angle of the electrical mounting cylinder 3 needs to be adjusted, the first motor 401 is controlled to work, and in conjunction with the first lead screw 402 and the first lead screw nut 4031, the sliding sleeve 403 moves downward. During the downward movement, the elastic folding plate 6 set inside the rectangular notch 201 pushes the upper end of the adjusting block 301 toward the first strip groove 202, thereby cooperating with the connecting rod 404 to adjust the angle of the adjusting block 301. During the downward movement of the sliding sleeve 403, the ear block 4033 drives the movable strip 801 and the second rack 8013 to move together. The second rack 8013 drives the gear 802 meshing with it to rotate, thereby driving the first rack 502 and the movable sleeve 5 to move upward, which can ensure that the adjusting block 301 can rotate.

[0057] When the first motor 401 is controlled to rotate in the reverse direction, it works in conjunction with the first lead screw 402 and the first lead screw nut 4031 to drive the sliding sleeve 403 to move upward, pulling the connecting rod 404 and the electrical mounting cylinder 3, and pulling the adjusting block 301 to a vertical position. During this process, the adjusting block 301 will squeeze the elastic folding plate 6, causing the elastic folding plate 6 to deform. The sliding pin 601 slides in the first strip-shaped slide 2012. During the upward movement of the sliding sleeve 403, it drives the movable strip 801 and the second rack 8013 to move upward, and works in conjunction with the gear 802 to drive the first rack 502 and the movable sleeve 5 to move downward, finally fitting the movable sleeve 5 onto the outside of the cylindrical part 302.

[0058] By controlling the operation of the second motor 702, and in conjunction with the second lead screw nut 2062 and the second lead screw 703, the mounting column 2 can be raised or lowered inside the mounting cylinder 1, thereby adjusting the lifting and lowering of the electrical mounting cylinder 3.

[0059] A method for installing a multibeam sonar probe mounting device includes the following steps:

[0060] S1: Install the probe, remove the transparent protective cover on the cylindrical part 302, install the multibeam sonar probe into the cylindrical part 302, and then install the transparent protective cover.

[0061] S2; Hull preparation: A circular hole adapted to the mounting cylinder 1 is opened in the middle or fore-and-aft position of the hull, and an inner liner is welded into the circular hole to ensure that the mounting cylinder 1 can be inserted into the inner liner.

[0062] S3: Device installation: Insert the mounting cylinder 1 into the circular hole from the upper part of the hull, and make sure that the sealing ring 102 fits precisely with the inner liner to achieve a seal. Then, fix the mounting cylinder 1 to the hull through the mounting flange 104.

[0063] S4: Device testing. Remove the top cover 105, connect the lifting assembly 7 and the power assembly to power, control the first motor 401 to work, drive the first lead screw 402 to rotate, and cooperate with the first lead screw nut 4031 to realize the rise and fall of the sliding sleeve 403.
