[0027] Embodiment 1

[0028] This embodiment provides a data acquisition bracket for a digital twin erosion test system, as Figure 1As shown in the figure, it includes a bracket body. The bracket body adopts a U-shaped structure, including a lower horizontal part 1. One end of the lower horizontal part 1 is perpendicularly fixed to the bottom end of the first vertical part 2, and the other end of the lower horizontal part 1 is perpendicularly fixed to the bottom end of the second vertical part 3. The lower horizontal part 1, the first vertical part 2, and the second vertical part 3 together form a U-shaped structure. The top ends of the first vertical part 2 and the second vertical part 3 are both perpendicularly connected to an upper horizontal part 4. The upper horizontal part 4 extends towards the outside direction, and multiple pulleys 5 are arranged at the outer end edge of the upper horizontal part 4. The pulleys 5 are used to cooperate with the top surface of the water tank, so that the entire data acquisition bracket can move along the water tank.

[0029] Furthermore, the pulley 5 adopts a traveling wheel with a braking function, which can be achieved by using existing technologies, and its specific structure will not be described in detail here.

[0030] An ADV clamping mechanism is arranged on one side of the lower horizontal part 1. The ADV clamping mechanism is used to clamp and fix the ADV6 (ultrasonic Doppler velocimeter). The center position of the bottom surface of the lower horizontal part 1 is fixedly connected to the top end of a cantilever 7. The cantilever 7 is provided with a wave height meter fixing mechanism, and the wave height meter fixing mechanism is used to fix the wave height meter 8. The bottom end of the cantilever 7 is inserted and connected to the vertical rod part of a T-shaped rod 9. At least one displacement sensor fixing mechanism is arranged on the horizontal rod part of the T-shaped rod 9, and the displacement sensor fixing mechanism is used to fix the displacement sensor.

[0031] In this embodiment, the lower horizontal part 1, the first vertical part 2, the second vertical part 3, and the two upper horizontal parts 4 all adopt a rectangular frame structure. There is a diagonal brace beam between the first vertical part 2 and the upper horizontal part 4, and there is a diagonal brace beam between the second vertical part 3 and the upper horizontal part 4.

[0032] There is a diagonal beam between the diagonals of the lower horizontal part 1. A disc-shaped support 10 is arranged at the intersection position of the two diagonal beams. The disc-shaped support 10 is fixedly connected to the top end of the cantilever 7.

[0033] Pulleys 5 are arranged at both ends of the side beams at the outer edges of the two upper horizontal parts 4. The pulleys 5 are used to cooperate with the top surface of the water tank.

[0034] An ADV clamping mechanism is arranged at the side beam with a longer length of the lower horizontal part 1, that is, a side beam perpendicular to the moving direction of the pulley 5 is provided with an ADV clamping mechanism.

[0035] The ADV clamping mechanism includes multiple groups of splint assemblies distributed in the up and down direction. In this embodiment, two groups of splint assemblies are arranged. Among them, the upper splint assembly is directly fixedly connected to the side beam of the lower horizontal part 1, and the lower splint assembly is fixedly connected to the side beam of the lower horizontal part 1 through a connecting frame.

[0036] The splint assembly includes a first splint 11 and a second splint 12 which are oppositely arranged. A vertical beam 13 passes through the space between the first splint 11 and the second splint 12. A first locking member is arranged between the first splint 11, the second splint 12 and the vertical beam 13 to lock and fix the first splint 11, the second splint 12 and the vertical beam 13.

[0037] The first locking member uses a first locking bolt 14. The first locking bolt 14 is vertically threadedly connected to the first splint 11 and / or the second splint 12. In this embodiment, the first locking bolt 14 is threadedly connected to both the first splint 11 and the second splint 12. By rotating the first locking bolt 14, the first locking bolt 14 can move along its own axis direction, so as to clamp or loosen the vertical beam 13.

[0038] Multiple groups of ADV hoop mechanisms 15 are arranged at the bottom of the vertical beam 13. The multiple groups of ADV hoop mechanisms 15 are used to clamp and fix the ADV6. The multiple groups of ADV hoop mechanisms 15 are distributed in the up-and-down direction. In this embodiment, two groups of ADV hoop mechanisms 15 are arranged.

[0039] The ADV hoop mechanism 15 includes a first hoop plate and a second hoop plate. One end of the first hoop plate and the second hoop plate is fixed to the vertical beam 13, and the other end is provided with a matching fixing hole. The first hoop plate and the second hoop plate are made of flexible metal and can produce a certain deformation. Both the first hoop plate and the second hoop plate have an arc-shaped plate section, and the arc-shaped plate section matches the ADV6 for clamping the ADV6.

[0040] A fixing bolt passes through the fixing hole, and a fixing nut is screwed on the fixing bolt, so as to realize that the first hoop plate and the second hoop plate clamp and fix the ADV6 by using the arc-shaped plate section.

[0041] During use, loosen the fixing nut to make the first hoop plate and the second hoop plate open and produce a certain deformation, then place the ADV6 into the space between the two arc-shaped plate sections, and then tighten the fixing nut, so that the two arc-shaped plate sections clamp and fix the ADV6.

[0042] In this embodiment, by loosening the first locking bolt 14, the height of the vertical beam 13 can be adjusted, and further the installation height of the ADV6 can be adjusted.

[0043] The cantilever 7 adopts a hollow tube structure, its top end is welded and fixed to the support 10, and its bottom end is inserted and connected to the vertical rod part of the T-shaped rod 9.

[0044] The T-shaped rod 9 includes a horizontal rod part, and a vertical rod part is vertically arranged at the middle position of the horizontal rod part.

[0045] Further, a second locking component is provided between the cantilever 7 and the vertical rod portion of the T-shaped rod 9. The second locking component uses a second locking bolt 15. The second locking bolt 15 is threadedly connected to the pipe wall of the cantilever 7. The second locking bolt 15 presses the vertical rod portion of the T-shaped rod 9 against the inner pipe surface of the cantilever 7. By loosening the second locking bolt 15, the T-shaped rod 9 can move up and down, thereby adjusting the height of the displacement sensor.

[0046] A displacement sensor fixing mechanism is provided on the horizontal rod section of the T-shaped rod 9. In this embodiment, multiple displacement sensor fixing mechanisms are provided, and preferably two are provided to install displacement sensors of different specifications.

[0047] The two displacement sensor fixing mechanisms are respectively arranged on both sides of the vertical rod section of the T-shaped rod 9.

[0048] The displacement sensor fixing mechanism includes a displacement sensor cross clamp 16. The displacement sensor cross clamp 16 can use an existing cross clamp, and its specific structure will not be described in detail here. The displacement sensor cross clamp 16 is clamped and fixed to the horizontal rod section of the T-shaped rod 9. The displacement sensor cross clamp 16 is fixedly connected to a fixing plate 17. The fixing plate 17 is arranged perpendicular to the horizontal rod section of the T-shaped rod 9. The fixing plate 17 is provided with fixing holes to fix the displacement sensor 18.

[0049] A wave height meter fixing mechanism is provided at a set position of the cantilever 7 for fixing the wave height meter 8.

[0050] The wave height meter fixing mechanism includes a first connecting member 19. The first connecting member 19 is fixed at a set position on the cantilever 7. The first connecting member 19 is fixedly connected to a first fixing rod 20. The first fixing rod 20 is fixed with a second connecting member 21. The second connecting member 21 is connected to a second fixing rod 22. The second fixing rod 22 is connected to a wave height meter cross clamp 23. The wave height meter cross clamp 23 is used to clamp and fix the wave height meter 8. The wave height meter cross clamp 23 can use an existing cross clamp, and its specific structure will not be described in detail here.

[0051] As Figure 2 shown, the first connecting member 19 is fixedly connected to the cantilever 7. The first connecting member 19 is provided with a first channel 19-1 for the first fixing rod 20 to pass through. The first fixing rod 20 passes through the first connecting member 19 through the first channel 19-1. The first connecting member 19 is threadedly connected with a third locking bolt 24. The rod portion of the third locking bolt 24 extends into the interior of the first channel 19-1 and can press the first fixing rod 20 against the inner side surface of the first channel 19-1. In this embodiment, the axis of the third locking bolt 24 is vertically arranged and can press down and fix the first fixing rod 20.

[0052] As Figure 3As shown in the figure, the second connecting member 21 is provided with a second channel 21-1 and a third channel 21-2. The second channel 21-1 and the third channel 21-2 are vertically distributed and perpendicular to each other. The second channel 21-1 is for the second fixing rod 22 to pass through, and the third channel 21-2 is for the first fixing rod 20 to pass through.

[0053] The first fixing rod 20 passes through the third channel 21-2. A fourth locking bolt with a vertically arranged axis is threadedly connected to the bottom of the second connecting member 21. The rod portion of the fourth locking bolt extends into the interior of the third channel 21-2 and presses the first fixing rod 20 against the inner side surface of the third channel 21-2, thereby realizing the fixation of the second connecting member 21 and the first fixing rod 20.

[0054] The second fixing rod 22 passes through the second channel 21-1. A fifth locking bolt 25 is threadedly connected to the top of the second connecting member 21. The axis of the fifth locking bolt 25 is vertically arranged. The rod portion of the fifth locking bolt 25 extends into the interior of the second channel 21-1 and presses the second fixing rod 22 against the inner side surface of the second channel 21-1, thereby realizing the fixation of the second fixing rod 23 and the second connecting member 21.

[0055] With the data acquisition bracket of this embodiment, the upper horizontal part is provided with a pulley 5 for cooperating with the top of the water tank. The data acquisition bracket can be moved along the water tank through the pulley, thereby adjusting the position of the data acquisition bracket in the water tank, meeting the acquisition of data at different positions in the water tank, and improving the applicability of the entire data acquisition bracket.

[0056] At the same time, the bracket body adopts an inward concave U-shaped structure and can be placed inside the water tank. Compared with the use of a portal-shaped column located outside the water tank, it has a small volume, less material consumption, reduces costs, and has good economy.

[0057] Embodiment 2

The water flow velocity information is collected through the ADV6, the wave height information of the water flow is collected through the wave height meter 8, and the displacement of the top of the bridge pier pile is collected through the displacement sensor 18.

[0060] When the entire bracket is located upstream of the water tank, it can collect the test data upstream of the water tank in the digital twin erosion test system. When it is necessary to collect the downstream data, the entire bracket can be moved to the downstream of the water tank through a pulley, and the T-shaped rod 9 can be rotated 180° to collect the downstream data.

[0061] Although the specific implementation modes of the present invention are described above in conjunction with the accompanying drawings, they do not limit the protection scope of the present invention.
