DETAILED DESCRIPTION

[0023] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example

[0025] like Figures 1 to 6 As shown, the present invention provides a marine topography survey vessel, comprising a hull 1, an electric platform 3, a retractable mechanism 4, a connecting mechanism 5, and an equipment platform 6. A slide rail 2 is fixed to the hull 1; the electric platform 3 is mounted on the slide rail 2 and can move along the slide rail 2. A worm gear mechanism 7 is provided on the top of the electric platform 3. A retractable motor 31 is also mounted on the electric platform 3. The output shaft of the retractable motor 31 is coaxially and fixedly connected to the worm of the worm gear mechanism 7. The worm gear of the worm gear mechanism 7 is rotatably mounted on the electric platform 3. One end of the main boom 8 is rotatably mounted on the electric platform 3 and coaxially and fixedly connected to the worm gear of the worm gear mechanism 7. When the angle of the main boom 8 needs to be adjusted, the retractable motor 31 drives the main boom 8 to rotate about one end of itself via the worm gear mechanism 7. The rotation angle range of the main boom 8 is 0 to 180 degrees, so that the other end of the main boom 8 can be adjusted to either side of the hull 1.

[0026] The retracting and extending mechanism 4 includes a main cantilever 8 and a telescopic arm 9. One end of the main cantilever 8 is rotatably mounted on the electric platform 3 through a worm gear mechanism 7. The telescopic arm 9 is rotatably connected to the other end of the main cantilever 8. A sleeve 26 is provided on the outer side of the telescopic arm 9. One side of the sleeve 26 is rotatably connected to the end of the main cantilever 8 through the main shaft. A drive motor 27 is also fixed to the end of the main cantilever 8. The output shaft of the drive motor 27 passes through the main cantilever 8 and is fixedly connected to the sleeve 26 through the main shaft. The drive motor 27 is used to drive the sleeve 26 to deflect. The deflection of the sleeve 26 can drive the telescopic arm 9 to rotate, thereby moving the other end of the telescopic arm 9 to the outside of the hull 1, so that the equipment platform 6 at the front end of the telescopic arm 9 can be smoothly placed underwater. The retracting and extending mechanism 4 is used to release or retract the equipment platform 6.

[0027] A groove 28 is provided on the side of the telescopic arm 9 , a rack 29 is fixed in the groove 28 , a gear set meshing with the rack 29 is rotatably mounted in the sliding sleeve 26 , and the gear set is driven by a telescopic motor 30 .

[0028] The operating principle of the retraction and extension mechanism 4 is as follows: in the initial state, the electric platform 3 is located at either end of the slide rail 2, the main cantilever 8 is positioned entirely on the inner side of the hull 1, and the telescopic arm 9 is retracted and parallel to the main cantilever 8, that is, neither the main cantilever 8 nor the telescopic arm 9 extends beyond the hull 1. Before conducting underwater topographic mapping, the underwater topographic mapping equipment is first installed within the equipment platform 6, which is then secured to the front end of the telescopic arm 9. The electric platform 3 is then moved toward the other end of the slide rail 2 to a designated position, allowing the front end of the main cantilever 8 to move to the outer side of the hull 1 and the main cantilever 8 to rotate to a horizontal position so that the main cantilever 8 is secured to the edge of the hull 1.

[0029] The electric platform 3 is based on existing technology. For example, a servo motor is installed at the bottom of the electric platform 3 to rotate a drive gear. A spur rack is installed on the inner side of one of the slide rails 2, parallel to the space between the gears, and meshes with the drive gear. The rack is fixed to the hull 1 to enable the electric platform 3 to move on the slide rail 2. The details will not be repeated here.

[0030] An adjustment block 21 is slidably mounted on the main boom 8. A hinge 22 is fixed to the adjustment block 21. A hanging rod 23 is fixed to one end of the hinge 22. Two clamping plates 24 are slidably mounted on the hanging rod 23. The two clamping plates 24 are connected by bolts 25, which are used to drive the two clamping plates 24 toward each other, thereby achieving a clamping action. By clamping the clamping plates 24 to the edge of the hull 1, the main boom 8 is supported and fixed, improving the stability of the main boom 8 in the working state.

[0031] The drive motor 27 rotates the sleeve 26 to a certain angle, moving the telescopic arm 9 and the equipment platform 6 toward the water surface. Once in position, the drive motor 27 is locked, and the telescopic motor 30, via a gear train, drives the rack 29, allowing the telescopic arm 9 to extend and retract relative to the sleeve 26. The equipment platform 6 at the front of the telescopic arm 9 is lowered underwater, and finally, the underwater topographic mapping equipment within the equipment platform 6 is used for surveying and mapping.

[0032] The above-mentioned gear set mainly includes a driving gear and a driven gear that mesh with each other (this is the existing technology and is not shown in the figure). The driving gear is coaxially fixedly connected to the output shaft of the telescopic motor 30, and the driven gear is rotatably installed in the sliding sleeve 26 and meshes with the rack 29. The details are not repeated here.

[0033] The connecting mechanism 5 is fixed to the front end of the telescopic arm 9, and the equipment platform 6 is fixed to the bottom of the connecting mechanism 5. The underwater topographic mapping equipment is installed in the equipment platform 6. The connecting mechanism 5 includes a ball head rod 10, a stabilizing frame 11, a locking washer 12, multiple guide rods 13 and multiple floats 14. The ball head rod 10 is fixed to the front end of the telescopic arm 9. A ring sleeve 15 is fixed at the center of the stabilizing frame 11. The inner diameter of the ring sleeve 15 is smaller than the diameter of the ball head on the ball head rod 10. The stabilizing frame 11 is slidably mounted on the ball head of the ball head rod 10 through the ring sleeve 15. The multiple guide rods 13 are vertically slidably mounted on the top plane of the stabilizing frame 11 and penetrate the stabilizing frame 11. The multiple floats 14 are fixed to the upper ends of the guide rods 13 in a one-to-one correspondence. The locking washer 12 is fixedly connected to the lower ends of the multiple guide rods 13. The center of the locking washer 12 is provided with a recess for accommodating the ball head rod 10. The equipment platform 6 is fixed to the bottom of the stabilizing frame 11.

[0034] During the rotation of the telescopic arm 9, the ring sleeve 15 at the center of the stabilizing frame 11 always maintains a sliding connection with the ball head of the ball head rod 10. Therefore, the equipment platform 6 always remains vertically downward under the action of gravity, and the rotation of the telescopic arm 9 will not cause the equipment platform 6 to tilt into the water, thereby improving the stability of the underwater topographic mapping equipment inside the equipment platform 6 when it enters the water. When the equipment platform 6 is completely lowered underwater, the multiple floats 14 rise upward due to the buoyancy and drive the locking pads 12 upward, causing the locking pads 12 to contact the ball head of the ball head rod 10. A friction block is fixed in the recess of the locking pad 12. The friction block can increase the friction between the locking pad 12 and the ball head of the ball head rod 10, so that the ring sleeve 15 at the center of the stabilizing frame 11 cannot continue to slide, thereby improving the stability of the equipment platform 6 underwater.

[0035] In addition, the equipment platform 6 includes a top protective plate 16, a protective side wall 17 and a bottom cover 18. The top protective plate 16 is fixedly connected to the stabilizing frame 11, the protective side wall 17 is fixed below the top protective plate 16, and the bottom cover 18 is fixed at the bottom of the protective side wall 17. The bottom cover 18, the protective side wall 17 and the top protective plate 16 are assembled together to form an equipment cavity, which is used to install underwater topographic mapping equipment. A transparent mapping window is fixed in the center of the bottom cover 18 to reduce the obstruction of the underwater topographic mapping equipment by the equipment platform 6. A plurality of equipment installation ports 19 for installing external equipment are provided on the protective side wall 17 to facilitate the installation and debugging of the underwater topographic mapping equipment. The edge of the bottom cover 18 is wrapped with an anti-collision rubber ring 20.
