Description

Technical Field

[0001] The present invention relates to the technical field of multi-beam sounding systems, and particularly to a method and device for expanding the scanning area of a multi-beam sounding system. Background Art

[0002] A multi-beam sounding system is a device that measures the seabed depth by transmitting and receiving sound waves. It uses an acoustic array installed on the bottom of a ship or a towed body to transmit an ultra-wide sound beam perpendicular to the course to the seabed, receives the seabed backscattering signal, and through analog / digital signal processing, forms multiple beams, and simultaneously obtains the water depth data of dozens or even hundreds of sampling points on the seabed strip.

[0003] Before the existing multi-beam sounding system is used, it needs to be installed on the ship's side structure with the help of installation parts. Therefore, after the installation of the multi-beam sounding system is completed, the staff still needs to adjust the working position of the multi-beam sounding system. And after the multi-beam sounding system is adjusted to the working position, it is also necessary to adjust the depth of the multi-beam sounding system instrument (when the instrument used by the multi-beam sounding system is in use, in order to improve the accuracy of the multi-beam sounding, it is necessary to lower the multi-beam sounding system instrument to a position 50-60 cm from the water surface). Therefore, due to the need for multiple preparatory works before use, the use of the multi-beam sounding system instrument is affected. And in order to prevent the multi-beam sounding system instrument placed in the water from being soaked for a long time and causing corrosion of the multi-beam sounding system instrument, when the multi-beam sounding system instrument is not in use, the staff needs to disassemble it, so as to achieve the effect of being able to store the disassembled multi-beam sounding system instrument. And when it is used later, the multi-beam sounding system instrument needs to be disassembled and assembled frequently. Therefore, there is also a situation where the workload of the staff is increased while affecting the use of the multi-beam sounding instrument, and thus the service life of the multi-beam sounding system instrument is reduced to a certain extent.

Detailed implementation manners

[0020] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further introduced in detail below in conjunction with the accompanying drawings.

[0021] Please refer to Figure 1-14 , an apparatus for expanding the scanning area of a multi-beam sounding system provided by an embodiment of the present invention includes a ship's side structure 1, and further includes a fixing plate 301 which is arranged on the ship's side structure 1 through a connecting component. A sliding plate 302 is arranged on the fixing plate 301, and the sliding plate 302 is driven by a driving source to slide horizontally on the fixing plate 301. A rotating seat 303 is rotatably arranged on the sliding plate 302, and a multi-beam sounding assembly 4 is slidably arranged on the rotating seat 303; the sliding plate 302 has the following stroke in the sliding state: In the first stroke, the sliding plate 302 slides horizontally along the fixed plate 301. In the second stroke, the rotating seat 303 rotates forward relative to the sliding plate 302. In the third stroke, the multi-beam sounding assembly 4 slides vertically relative to the rotating seat 303. In the fourth stroke, the rotating seat 303 rotates reversely relative to the sliding plate 302.

[0022] In the above technical solution, by using the driving source to drive the sliding plate 302 to slide horizontally along the fixed plate 301, and while the sliding plate 302 slides horizontally, it can also drive the sliding seat 306 to slide horizontally in the same direction as the sliding plate 302. With the help of the first chute 3012 on the fixed plate 301, it can make the rotating seat 303 on the sliding plate 302 flip during the horizontal sliding process of the sliding plate 302. When the sliding plate 302 moves to an appropriate position, by using the reverse sliding of the sliding seat 306, it can drive the multi-beam sounding assembly 4 on the rotating seat 303 to slide relative to the rotating seat 303, so that when the rotating seat 303 flips to the detection position, it can automatically adjust the depth of the multi-beam sounding assembly 4 on the rotating seat 303. And by using the driving source to drive the sliding plate 302 to continuously slide horizontally along the fixed plate 301, and with the help of the first chute 3012 on the fixed plate 301, it can not only flip and reset the rotating seat 303 on the sliding plate 302, but also reverse-flip the rotating seat 303, so as to temporarily store the multi-beam sounding assembly 4 on the rotating seat 303, avoiding the situation that the multi-beam sounding assembly 4 needs to be repeatedly disassembled and assembled when not in use, which increases the workload of the staff and affects the use of the multi-beam sounding assembly 4. And by storing the multi-beam sounding assembly 4, it can also avoid the situation that the multi-beam sounding assembly 4 is soaked in water for a long time when not in use, resulting in corrosion of the multi-beam sounding assembly 4. Therefore, it also improves the service life of the multi-beam sounding assembly 4 to a certain extent.

[0023] Specifically, the connection assembly includes a mounting plate 21 provided on the ship's side structure 1. A plurality of bolts 22 are threadedly connected to the mounting plate 21. A gasket 23 is rotatably connected to the end face of the bolt 22, and the gasket 23 is movably abutted against the ship's side structure 1.

[0024] In the above technical solution, by using the connecting component, after the mounting plate 21 is installed at an appropriate position on the ship's side, the multiple bolts 22 on the mounting plate 21 can be rotated, so that the gasket 23 can abut against the ship's side structure 1 under the action of the bolts 22, thereby achieving the effect of being able to quickly disassemble and assemble the multi-beam sounding component 4 on the fixing plate 301, and further facilitating the use of the multi-beam sounding component 4.

[0025] Specifically, the driving source is a cylinder, the cylinder is fixedly installed on the mounting plate 21, and the output end of the cylinder is fixedly installed on the sliding plate 302.

[0026] In the above technical solution, by using the telescoping of the cylinder, the effect of enabling the sliding plate 302 to reciprocate horizontally along the fixing plate 301 is achieved.

[0027] Specifically, a slide rail 3011 is fixedly installed on the fixing plate 301, a slide frame 3021 is fixedly installed on the sliding plate 302, and the slide frame 3021 is slidably arranged on the slide rail 3011.

[0028] In the above technical solution, by using the slide frame 3021 on the sliding plate 302 and the slide rail 3011 on the fixing plate 301, the effect of being able to limit the sliding direction and the slidable distance of the sliding plate 302 is achieved.

[0029] Specifically, a rotating shaft 3022 is rotatably arranged on the sliding plate 302. One end of the rotating shaft 3022 is fixedly installed with a connecting plate 3023, a slider 3024 is fixedly installed on the connecting plate 3023, a first chute 3012 is formed on the fixing plate 301, the slider 3024 is slidably arranged in the first chute 3012, and the first chute 3012 is in a "V" shape; a rotating seat 303 is fixedly installed on the end face of the other end of the rotating shaft 3022.

[0030] In the above technical solution, by using the driving source to control the sliding plate 302 to slide horizontally along the fixing plate 301, the slider 3024 on the connecting plate 3023 will slide along the V-shaped first chute 3012 under the drive of the sliding plate 302, so that when the slider 3024 on the connecting plate 3023 slides to the lowest end of the V-shaped chute, the effect of being able to flip it by 90° is achieved.

[0031] Specifically, a rotating rod 304 is rotatably arranged on the rotating seat 303, and a first gear 305 is rotatably arranged at one end of the rotating rod 304; a sliding seat 306 is arranged on the fixing plate 301, which receives the sliding drive of the sliding plate 302 to enable the sliding seat 306 to slide horizontally relative to the fixing plate 301. A second spring 307 is arranged between the sliding seat 306 and the fixing plate 301, and a first rack 308 meshing with the first gear 305 is fixedly installed on the top surface of the sliding seat 306.

[0032] Further, a fixed frame 3062 is fixedly installed on the sliding seat 306. A movable plate 3063 is slidably inserted into the fixed frame 3062. A fixed rod 3025 that abuts and cooperates with the movable plate 3063 is fixedly installed on the bottom surface of the sliding plate 302. A first spring 3064 is provided between the movable plate 3063 and the fixed frame 3062. Abutting rod 3065 is fixedly installed on the movable plate 3063. An abutting plate 3014 that abuts and cooperates with the abutting rod 3065 is fixedly installed on the fixed plate 301.

[0033] Furthermore, a second sliding groove 3013 is also formed on the fixed plate 301. A guiding block 3061 is fixedly installed on the sliding seat 306. One end of the second spring 307 is fixedly installed on the guiding block 3061, and the other end is fixedly installed in the second sliding groove 3013 through a vertical plate.

[0034] In the above technical solution, by using the driving source, when the sliding plate 302 slides horizontally along the slide rail 3011 on the fixed plate 301, the fixed rod 3025 on the sliding plate 302 abuts against the movable plate 3063 on the fixed frame 3062. Thus, while the sliding plate 302 slides horizontally, it can drive the sliding seat 306 to slide together with the sliding plate 302 while overcoming the elastic force of the second spring 307. When the sliding plate 302 moves to a certain position and the rotating seat 303 on the sliding plate 302 rotates 90°, the first gear 305 on the rotating seat 303 will mesh with the first rack 308 on the sliding seat 306. Then, by means of the abutting plate 3014 on the fixed plate 301, the abutting plate 3014 can abut against the abutting rod 3065 on the movable plate 3063, so that the movable plate 3063 can slide along the fixed frame 3062 while overcoming the elastic force of the first spring 3064, and further enable the movable plate 3063 to avoid the fixed rod 3025 on the sliding plate 302. As a result, the sliding seat 306 can slide reversely along the fixed plate 301 under the action of the elastic force of the second spring 307. Therefore, by means of the mutual cooperation between the first rack 308 on the sliding seat 306 and the first gear 305 on the rotating rod 304, the effect of enabling the rotating rod 304 on the rotating seat 303 to rotate is achieved.

[0035] Specifically, tooth blocks 3081 are slidably arranged at both ends of the first rack 308 corresponding to each other. A third spring 3082 is provided between the tooth block 3081 and the first rack 308. Both ends of the third spring 3082 are fixedly installed on the first rack 308 and the tooth block 3081 respectively.

[0036] In the above technical solution, by utilizing the slidable tooth blocks 3081 at both ends of the tooth block 3081, the buffering effect between the first rack 308 and the first gear 305 can be increased, and further, no matter how the first gear 305 moves, the first gear 305 can be meshed with the first rack 308 on the sliding seat 306.

[0037] Specifically, a groove 3051 is formed on the surface of the first gear 305, a pawl 3052 is arranged inside the groove 3051, and a ratchet wheel 3053 matched with the pawl 3052 is fixedly installed on the peripheral surface of the rotating rod 304.

[0038] In the above technical solution, by utilizing the ratchet wheel 3053 and the pawl 3052, the effect of enabling the rotating rod 304 on the rotating seat 303 to rotate in one direction can be achieved.

[0039] Specifically, a second gear 309 is also fixedly installed on the peripheral surface of the rotating rod 304, a second rack 310 meshed with the second gear 309 is slidably arranged on the rotating seat 303, a connecting rod 311 is fixedly installed on one end surface of the second rack 310, and the multi-beam sounding assembly 4 is fixedly installed on the end surface of the connecting rod 311.

[0040] In the above technical solution, by utilizing the sliding seat 306, the first rack 308 on the sliding seat 306 can slide reversely under the action of the elastic force of the second spring 307. Thus, through the mutual cooperation between the first gear 305 and the first rack 308, the rotating rod 304 on the rotating seat 303 can be rotated. By using the rotation of the rotating rod 304 to drive the rotation of the second gear 309, and with the mutual cooperation between the second gear 309 and the second rack 310, after the rotating seat 303 on the sliding plate 302 is flipped, the second rack 310 can be driven to slide relative to the rotating seat 303, and further, the effect of driving the multi-beam sounding assembly 4 on the connecting rod 311 to slide vertically can be achieved.

[0041] Specifically, the multi-beam sounding assembly 4 includes a connecting seat 401 fixedly installed on the end surface of the connecting rod 311. A first motor 402 is fixedly installed on the connecting seat 401. An output end of the first motor 402 is fixedly installed with a worm 403. The worm 403 is fixedly installed on the bottom surface of the connecting seat 401 through a support plate 404. A rotating frame 406 is rotatably arranged on the support plate 404. A rotating rod 407 is rotatably arranged on the rotating frame 406. A worm gear 408 matched with the worm 403 is fixedly installed on the peripheral surface of the rotating rod 407. An installation seat 409 is fixedly installed on the peripheral surface of the rotating rod 407. An instrument main body 410 is fixedly installed on the installation seat 409.

[0042] Furthermore, a second motor 405 is fixedly installed on the bottom surface of the connecting seat 401, and a rotating frame 406 is fixedly installed on the output end of the second motor 405.

[0043] In the above technical solution, by using the first motor 402 on the connecting seat 401, the worm 403 on the support plate 404 can rotate under the action of the first motor 402, and by means of the mutual cooperation between the worm 403 and the worm 403, when the worm gear 408 rotates, the instrument main body 410 on the mounting seat 409 can swing left and right under the drive of the worm 403 and the rotating rod 407; and by using the second motor 405 on the connecting seat 401, the rotating frame 406 can swing back and forth under the action of the second motor 405, and further the instrument main body 410 on the mounting seat 409 can swing back and forth under the drive of the rotating frame 406. Therefore, by using the first motor 402 to control the left and right swing adjustment of the instrument main body 410 on the connecting seat 401, and using the second motor 405 to control the front and back swing adjustment of the instrument main body 410 on the connecting seat 401, the effect of being able to adjust the irradiation angle and range of the instrument main body 410 on the mounting seat 409 as needed is achieved, and further the adaptability of the instrument main body 410 on the mounting seat 409 in different environments is improved.

[0044] The present invention also provides a method for expanding the scanning area of a multi-beam sounding system, which is used for a device for expanding the scanning area of a multi-beam sounding system according to any one of the above, and includes the following steps: S1: Drive the sliding plate 302 to slide horizontally along the fixed plate 301 through a driving source; S2: During the process of the connecting plate 3023 on the sliding plate 302 sliding along the first chute 3012, it can drive the rotating seat 303 to perform a forward 90° flip; S3: While the sliding plate 302 slides horizontally along the fixed plate 301, the sliding plate 302 drives the sliding seat 306 to slide horizontally together against the elastic force of the second spring 307; S4: After the rotating seat 303 is flipped forward by 90°, drive the reverse sliding of the sliding seat 306 through the second spring 307, so as to drive the multi-beam sounding assembly 4 to slide relative to the rotating seat 303; S5: By driving the sliding plate 302 to continuously slide horizontally along the fixed plate 301 through a driving source, while driving the rotating seat 303 to perform a reset flip, it can also drive the rotating seat 303 to perform a reverse 90° flip.

[0045] Working principle: When in use, by utilizing the connecting components, after the mounting plate 21 is installed at an appropriate position on the ship's side, multiple bolts 22 on the mounting plate 21 can be rotated, enabling the gasket 23 to abut against the ship's side structure 1 under the action of the bolts 22. Thus, the fixing plate 301 can be quickly installed on the ship's side structure 1. Then, by utilizing the telescoping of the cylinder, the sliding plate 302 can reciprocate horizontally on the fixing plate 301 along the slide rail 3011. When the driving source controls the sliding plate 302 to slide horizontally along the fixing plate 301, the slider 3024 on the connecting plate 3023 will slide along the V-shaped first chute 3012 under the drive of the sliding plate 302. When the slider 3024 on the connecting plate 3023 slides to the lowest end of the V-shaped chute, it can be flipped by 90°. When the driving source makes the sliding plate 302 slide horizontally along the slide rail 3011 on the fixing plate 301, by means of the fixed rod 3025 on the sliding plate 302 abutting against the movable plate 3063 on the fixed frame 3062, the sliding plate 302 can drive the sliding seat 306 to slide together with the sliding plate 302 while overcoming the elastic force of the second spring 307. After the sliding plate 302 moves to a certain position and the rotating seat 303 on the sliding plate 302 is flipped by 90°, the first gear 305 on the rotating seat 303 will mesh with the first rack 308 on the sliding seat 306. Then, by means of the abutting plate 3014 on the fixing plate 301, the abutting plate 3014 can abut against the abutting rod 3065 on the movable plate 3063, enabling the movable plate 3063 to slide along the fixed frame 3062 while overcoming the elastic force of the first spring 3064. Thus, the movable plate 3063 can avoid the fixed rod 3025 on the sliding plate 302, allowing the sliding seat 306 to slide reversely along the fixing plate 301 under the elastic force of the second spring 307. Therefore, through the mutual cooperation between the first rack 308 on the sliding seat 306 and the first gear 305 on the rotating rod 304, the rotating rod 304 on the rotating seat 303 rotates. By utilizing the ratchet 3053 and the pawl 3052, the rotating rod 304 on the rotating seat 303 can be rotated in one direction. Finally, by utilizing the sliding seat 306, the first rack 308 on the sliding seat 306 can slide reversely under the elastic force of the second spring 307. Thus, through the mutual cooperation between the first gear 305 and the first rack 308, the rotating rod 304 on the rotating seat 303 rotates.
