Abstract
Description
Technical Field
[0001] This utility model relates to the field of measuring instrument technology, and in particular to a stabilization device for an underwater three-dimensional laser measuring instrument. Background Technology
[0002] Underwater 3D laser measuring instruments emit laser light and receive reflected light, using triangulation principles or related algorithms to calculate the 3D coordinates of an object's surface, thereby constructing a 3D model of the object. This process enables non-contact, high-precision measurement of underwater objects.
[0003] Currently, most 3D laser measuring instruments are mounted on auxiliary devices, which are then vertically inserted into the ground via a rod at the bottom of the auxiliary device to stabilize the instrument. However, this makes it inconvenient to adjust the measurement height during actual use, and the device is prone to lateral tilting in water, resulting in low stability. Therefore, we propose a stabilization device for underwater 3D laser measuring instruments. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Example 1;
[0025] Reference Figures 1-2 A stabilizing device for an underwater three-dimensional laser measuring instrument includes a housing 1. Multiple mounting sleeves 12 are fixedly installed on the bottom of the housing 1. Multiple conical rods 4 are provided on the bottom of the housing 1, and the conical rods 4 are threadedly connected to the mounting sleeves 12 respectively. Multiple adjusting rods 5 are slidably connected to the top of the housing 1. The ends of the adjusting rods 5 located outside the housing 1 are fixedly connected to the same measuring instrument body 3. The ends of the adjusting rods 5 located inside the housing 1 are fixedly installed to the same connecting plate 7. An adjusting mechanism is provided on the housing 1. The structure includes an adjusting block 8 fixedly installed on the bottom of the connecting plate 7, a threaded rod 11 rotatably connected between the inner walls of the two sides of the housing 1, a moving block 10 threadedly fitted on the threaded rod 11, an upper block 9 fixedly installed on the top of the moving block 10, one end of the threaded rod 11 penetrating through one inner wall of the housing 1 and a handwheel 2 fixedly installed thereon, multiple adjusting springs 6 fixedly connected between the connecting plate 7 and the inner top of the housing 1, and the moving block 10 slidingly connected to the other two inner walls of the housing 1. The vertical cross-sections of the upper block 9 and the adjusting block 8 are both right-angled trapezoidal shapes.
[0026] In use, this utility model uses multiple conical rods 4 threadedly connected to multiple mounting sleeves 12, allowing the conical rods 4 to be screwed into the mounting sleeves 12. This also facilitates subsequent disassembly and maintenance of the conical rods 4. The device is then placed in water, and the conical rods 4 are vertically inserted into the soil, thus improving the stability during measurement. Measurement can be performed by setting the measuring instrument body 3. By rotating the handwheel 2 in the forward direction, the threaded rod 11 can be rotated in one direction. Since the moving block 10 is slidably connected to the inner walls of the other two sides of the housing 1, it cannot rotate. This allows the moving block 10 and the upper block 9 to move towards the adjusting block 8. Through the interaction between the inclined surface on the upper block 9 and the inclined surface on the adjusting block 8, the adjusting block 8, the connecting plate 7, the multiple adjusting rods 5, and the measuring instrument body 3 can move upward. The adjusting spring 6 is compressed, thereby adjusting the measurement height.
[0027] Example 2:
[0028] Reference Figure 3 Compared to Embodiment 1, this embodiment is superior in that a lower block 21 is fixedly installed at the bottom of the moving block 10, a pressure plate 14 is provided below the lower block 21, an auxiliary block 13 is fixedly installed at the top of the pressure plate 14, a first return spring 16 is fixedly connected between the pressure plate 14 and the inner bottom of the housing 1, and a plurality of auxiliary mechanisms are provided below the pressure plate 14. The auxiliary mechanisms include a conical pressure rod 15 that passes through and is slidably connected to the inner bottom of the housing 1, and one end of the conical pressure rod 15 located inside the housing 1 is fixed to the bottom of the pressure plate 14. The conical insert 4 has a cavity 22 inside, and one end of the conical pressure rod 15 extends into the cavity 22. Both sides of the conical pressure rod 15 have protrusions 19. Circular holes 17 are opened on both inner walls of the cavity 22. Conical auxiliary rods 18 are fixedly installed on the side wall of the two protrusions 19 that are far apart from each other. One end of a second return spring 20 is fixedly connected to the side wall of the two protrusions 19 that are far apart from each other. The other ends of the two second return springs 20 are respectively fixedly connected to the inner walls of both sides of the cavity 22. The lower block 21 and the auxiliary block... The vertical cross-section of 13 is in the shape of a right trapezoid. The two conical auxiliary rods 18 are respectively adapted to the two circular holes 17. The protrusion 19 and the conical auxiliary rods 18 are integrally formed. During the movement of the moving block 10 in Embodiment 1, it will drive the lower block 21 to move closer to the auxiliary block 13. Thus, before the inclined surface on the upper block 9 and the inclined surface on the adjusting block 8 cooperate with each other, the inclined surface on the lower block 21 will cooperate with the inclined surface on the auxiliary block 13, thereby enabling the pressure plate 14 and the multiple conical pressure rods 15 to move downward. The first return spring 16 As the multiple conical pressure rods 15 are compressed and move downwards, the curved surfaces of the conical pressure rods 15 will cooperate with the curved surfaces of the protrusions 19, thereby enabling the two conical auxiliary rods 18 to move away from each other and finally be inserted laterally into the soil through the circular hole 17, further improving the stability during measurement. The second return spring 20 is compressed, and by rotating the handwheel 2 in the opposite direction, the elastic force generated by the compression of the first return spring 16, the second return spring 20 and the adjusting spring 6 can reset the adjusting block 8, the auxiliary block 13 and the conical pressure rods 15.
[0029] Example 3:
[0030] Reference Figure 4 The advantage of this embodiment over the second embodiment is that the outer wall of the handwheel 2 is provided with uniformly distributed anti-slip blocks 23, which improves the friction when the handwheel 2 is rotated in the forward or reverse direction, making it more practical.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
