[0003] A Chinese patent document with authorization announcement number CN220038121U proposes a vertical positioning device for marine surveying and mapping, including: a mounting frame assembly, on which a vertical component is provided to prevent the vertical and positioning from being affected by shaking caused by waves when surveying on the sea surface, and two limit components for convenient fixed positioning and installation on ships, the vertical component includes an annular groove plate, an annular connecting plate 1, two mounting cylinders 1, two rotating rods 1, an annular connecting plate 2, two mounting cylinders 2, two rotating rods 2 and a disc, the annular groove plate is arranged on the mounting frame assembly, the annular connecting plate 1 is rotatably mounted on the annular groove plate, the two mounting cylinders 1 are fixedly mounted on the inner wall of the annular connecting plate 1, and the two rotating rods 1 are respectively rotatably mounted in the two mounting cylinders 1.

[0004] In the above application, although it has the advantage of preventing the shaking caused by the impact of waves, which would deviate from the verticality and positioning and affect the surveying and mapping, there is no device to fix the disc, and the hull on the sea surface shakes with the waves at any time, which may cause the device to always be looking for a horizontal state and cannot stabilize, causing the detection value to always jump, and thus it is impossible to obtain accurate detection results.

[0005] In view of the problems existing in the background technology, a vertical positioning device for marine surveying and mapping is proposed.

[0006] The utility model proposes a vertical positioning device for marine surveying and mapping, including a base plate, a mounting platform, a positioning assembly and a support member.

DETAILED DESCRIPTION

[0023] Embodiment 1

[0024] like Figure 1-5 As shown, the utility model proposes a vertical positioning device for marine surveying and mapping, and this embodiment includes: the centers of gravity of the hemispherical base 4, the mounting platform 5, the suspension rod 6 and the lead ball 7 are all on the same axis, and the axis is located at the center of the mounting platform 5. The mass of the lead ball 7 is relatively large, ensuring that the mounting platform 5 can always maintain a horizontal state under the traction of the lead ball 7.

[0025] It is further explained that the positioning assembly 8 includes a positioning plate 814 for limiting the mounting platform 5 by angle adjustment, a positioning member 81 for positioning the positioning plate 814 by height adjustment, and a limiting member 82 for limiting the positioning member 81 by clamping adjustment. The positioning member 81 includes a sliding tube 811 that is connected to multiple brackets 2 in a one-to-one correspondence and can generate deformation; the upper ends of the multiple sliding tubes 811 are all open, and the openings are all slidably connected to sliding columns 812; the upper ends of the sliding columns 812 are all connected to hinge balls 813; the upper ends of the hinge balls 813 are provided with a positioning plate 814; the positioning plate 814 and the multiple hinge balls 813 are all hinged. The positioning plate 814 can be operated to make the positioning plate 814 and the mounting platform 5 in a parallel state, and then the positioning plate 814 is lifted to fit with the bottom surface of the mounting platform 5, so as to achieve the positioning of the mounting platform 5.

[0026] It is further explained that the limiting member 82 includes a tube clamp 821 connected to the upper end of the outer wall of the sliding tube 811; one side of the tube clamp 821 is open, and a connecting block 822 is symmetrically connected to the opening; a connecting rod 823 is slidably connected to the two connecting blocks 822; the connecting rod 823 runs through the two connecting blocks 822, one end of which is connected to a limiting plate 824, and the other end is connected to a limiting column 825; an eccentric sleeve column 826 is rotatably sleeved on the limiting column 825; a sliding groove 827 for the sliding of the connecting rod 823 is provided on the side wall of the sleeve column 826, and a trigger handle 828 is also connected to the sleeve column 826. By triggering the trigger handle 828, the tube clamp 821 squeezes the sliding tube 811 to deform the sliding tube 811, and squeezes the sliding column 812, thereby limiting the sliding column 812 and preventing the sliding column 812 from sliding up and down along the sliding tube 811, so that the positioning member 81 can stably position the mounting platform 5.

[0027] It is further explained that the pipe clamp 821 is provided with an insert block 8210, which is engaged with a slot 829 provided on the pull handle 828. When the pull handle 828 is pulled, the insert block 8210 is engaged with the slot 829, which can prevent the pull handle 828 from rebounding and causing the limit of the sliding column 812 to loosen.

[0028] It is further explained that a rubber pad 8211 is connected to the connecting rod 823; the rubber pad 8211 is arranged between the sleeve column 826 and the connecting block 822 on the corresponding side, thereby increasing the friction force on the trigger handle 828 and preventing the trigger handle 828 from rebounding.

[0029] Embodiment 2

[0030] like Figure 1-5 As shown, the vertical positioning device for marine surveying and mapping proposed by the utility model, compared with the first embodiment, this embodiment further includes: the centers of gravity of the hemispherical base 4, the mounting platform 5, the suspension rod 6 and the lead ball 7 are all on the same axis, and the axis is located at the center of the mounting platform 5. The mass of the lead ball 7 is relatively large, ensuring that the mounting platform 5 can always maintain a horizontal state under the traction of the lead ball 7.

[0031] It is further explained that the support member 9 includes a leg 1 91 rotatably connected to the plurality of brackets 2; the other side of the leg 1 91 is rotatably connected to the leg 2 92; the support member 9 provides support for the device by opening the leg 1 91 and the leg 2 92 and standing on the ground. This can prevent the device from shaking or sliding with the hull when the hull shakes, thereby affecting the detection results. When not in use, the leg 1 91 and the leg 2 92 can be folded upwards and stored.

[0032] The working principle of the utility model is as follows: when working, first open the support leg 1 91 and the support leg 2 92 downwards respectively, so that the support leg 2 92 is supported on the ground to provide support for the device, to prevent the device from shaking or sliding with the hull when the hull shakes, affecting the detection result. Since the mass of the shot 7 is large, when the hull shakes, the hemispherical base 4 will shake in the support frame 3, and finally maintain balance under the traction of the shot 7, so that the suspension rod 6 connected to the shot 7 always remains in a vertical state, and the mounting platform 5 always remains in a horizontal state. When it is necessary to detect, first insert the detection device into the groove set at the upper end of the mounting platform 5 to fix the detection device. Then adjust the positioning plate 814 so that the upper end of the positioning plate 814 fits with the bottom surface of the mounting platform 5, and the mounting platform 5 is positioned. During adjustment, the sliding column 812 will slide up along the sliding tube 811. Then, the lever 828 is pulled to rotate the sleeve 826 along the limiting column 825, and the axis of the sleeve 826 is moved close to the adjacent connection block 822, thereby squeezing the connection block 822, so that the two connection blocks 822 are close to each other along the connecting rod 823, and the diameter of the pipe clamp 821 is reduced, thereby squeezing the sliding tube 811. Since the sliding tube 811 can be deformed, it can further squeeze the sliding column 812, thereby limiting the sliding column 812 and preventing the sliding column 812 from falling, resulting in inaccurate positioning of the mounting platform 5. At the same time, when the lever 828 is pulled, the connecting rod 823 will slide in the slide groove 827, and finally the insert block 8210 will be clamped into the slot 829, and the sleeve 826 will squeeze the rubber pad 8211 to prevent the lever 828 from rebounding. At this time, the positioning of the mounting platform 5 is completed, and it can be observed by a level meter and tested when the mounting platform 5 is in a horizontal position.

[0033] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
