Description

Technical Field

[0001] This utility model relates to the field of video monitoring technology. More specifically, this utility model relates to a video displacement meter. Background Technology

[0002] A video displacement meter is a device used to measure and monitor structural displacement. It employs digital image correlation technology and Internet of Things (IoT) technology to enable multi-point displacement monitoring and early warning, making it suitable for long-term monitoring and early warning of structures such as bridges, tunnels, dams, slope protection, mountains, and buildings. Due to the long-term monitoring requirements of video displacement meters, their installation necessitates a more stable mounting structure to minimize the impact of environmental vibrations.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] like Figures 1-4 As shown, this utility model provides a video displacement meter, including: a base and a video displacement meter body disposed on the base, the base including:

[0034] Mounting base plate 1, which can be provided with mounting holes for bolts to pass through, and the mounting plate is fixed to the pole or other base on which the video displacement meter is placed by bolts;

[0035] The first block 2 is disposed on the mounting base plate 1, and a first rotating shaft 3 with its axis horizontally disposed is connected to the first block 2.

[0036] The second block 4 has a first clamping opening, and the first rotating shaft 3 passes through the first clamping opening so that the second block 4 can rotate around the first rotating shaft 3. The two first clamping parts of the first clamping opening are detachably locked by the first bolt 5 to fix the second block 4.

[0037] A second rotating shaft 6 is provided below the main body of the video displacement meter. A second clamping port is also provided on the second block 4. The second rotating shaft 6 passes through the second clamping port. The second rotating shaft 6 and the first rotating shaft 3 are in a perpendicular relationship. The two second clamping parts forming the second clamping port are detachably locked by the second bolt 7 to fix the second rotating shaft 6.

[0038] Here, the first block 2, the second block 4, the first rotating shaft 3, and the second rotating shaft 6 are all made of solid steel.

[0039] The above embodiment is used as follows: First, the mounting base plate 1 is fixed in the pre-designed position with bolts. Then, the first bolt 5 is loosened so that the second block 4 can rotate around the first rotation axis 3, thereby realizing the pitch angle adjustment of the second block 4 and the video displacement meter body connected to the second block 4. After the pitch angle of the video displacement meter body is adjusted to the correct position, the first bolt 5 is tightened to fix the second block 4. Then, the second bolt 7 is loosened so that the video displacement meter body can rotate around the second rotation axis 6, thereby realizing the orientation adjustment of the video displacement meter body. After the orientation of the video displacement meter body is adjusted to the correct position, the second bolt 7 is tightened to fix the second rotation axis 6.

[0040] As can be seen from the above usage process, adjusting the orientation and pitch angle of the video displacement meter body is relatively simple and convenient. Furthermore, since the first block 2, the second block 4, the first rotating shaft 3, and the second rotating shaft 6 are all solid blocks, the stability of the base is greatly enhanced, reducing the impact of external vibrations on the video displacement meter.

[0041] In another embodiment, the first clamping opening includes a first through hole adapted to the first rotating shaft 3, and a first slit extending from the inner wall of the first through hole to the surface of the second block 4, the first slit being opened along the axial direction of the first through hole.

[0042] In this embodiment, the first clamping opening is configured as a first through hole and a first slit adapted to the first rotating shaft 3. The first through hole has a large contact area with the first rotating shaft 3, which can better absorb and disperse the vibration transmitted by the first rotating shaft 3. The first slit is used to realize the tightening clamping effect of the first clamping opening. At the same time, the first slit requires less processing on the second block 4, is simple to process, and can ensure the thickness of the second block 4 as much as possible, which is conducive to enhancing the stability of the structure.

[0043] In another embodiment, a first countersunk hole is provided on a first clamping part located on one side of the first slit. The first countersunk hole extends from the surface of the first clamping part to the inner wall of one side of the first slit. A first threaded hole is provided on a first clamping part located on the other side of the first slit. The first threaded hole is opposite to the first countersunk hole and extends from the inner wall of the other side of the first slit into the interior of the first clamping part. The first bolt 5 passes through the first countersunk hole and is threadedly connected to the first threaded hole.

[0044] In this embodiment, the two first clamping parts forming the first clamping opening are connected by a first bolt 5. The contact area between the first bolt 5 and the first countersunk hole and the first threaded hole is large, which can better absorb and disperse the vibration in the second block 4 and ensure the stability of the structure as much as possible.

[0045] In another embodiment, two sets of first countersunk holes and first threaded holes are provided on the two first clamping portions forming the first clamping opening, and the first countersunk holes and the first threaded holes opposite to them are set as a set.

[0046] In this embodiment, two sets of first countersunk holes and first threaded holes are provided, and two first bolts 5 are used to connect the two first clamping parts forming the first clamping port. This can strengthen the clamping effect of the first clamping port on the first rotating shaft 3, ensure the stability of the contact surface between the first rotating shaft 3 and the first through hole, and thus ensure the structural stability.

[0047] In another embodiment, the second clamping port includes a second through hole adapted to the second rotating shaft 6, and a second slit extending from the inner wall of the second through hole to the surface of the second block 4. The second slit is opened along the axial direction of the second through hole, and the axis of the second through hole is perpendicular to the axis of the first through hole.

[0048] In this embodiment, the second clamping opening is configured as a second through hole and a second slit adapted to the second rotating shaft 6. The second through hole has a large contact area with the second rotating shaft 6, which can better absorb and disperse the vibration transmitted from the second block 4. The second slit is used to achieve the tightening clamping effect of the second clamping opening. At the same time, the second slit requires less machining on the second block 4, is simple to machine, and can ensure the thickness of the second block 4 as much as possible, which is conducive to enhancing the stability of the structure.

[0049] In another embodiment, a second countersunk hole is provided on the second clamping part located on one side of the second slit. The second countersunk hole extends from the surface of the second clamping part to the inner wall of one side of the second slit. A second threaded hole is provided on the second clamping part located on the other side of the second slit. The second threaded hole is opposite to the second countersunk hole and extends from the inner wall of the other side of the second slit into the interior of the second clamping part. The second bolt 7 passes through the second countersunk hole and is threadedly connected to the second threaded hole.

[0050] In this embodiment, the two second clamping parts forming the second clamping opening are connected by a second bolt 7. The contact area between the second bolt 7 and the second countersunk hole and the second threaded hole is large, which can better absorb and disperse the vibration in the second block 4 and ensure the stability of the structure as much as possible.

[0051] In another embodiment, two sets of second countersunk holes and second threaded holes are provided on the two second clamping portions forming the second clamping opening, and the second countersunk holes and the second threaded holes opposite to them are set as a set.

[0052] In this embodiment, two sets of second countersunk holes and second threaded holes are provided, and two second bolts 7 are used to connect the two second clamping parts forming the second clamping port. This can strengthen the clamping effect of the second clamping port on the second rotating shaft 6, ensure the stability of the contact surface between the second rotating shaft 6 and the second through hole, and thus ensure the structural stability.

[0053] In another embodiment, a third clamping opening is provided on the first block 2, and the first rotating shaft 3 is also inserted through the third clamping opening. The two third clamping parts forming the third clamping opening are detachably locked by a third bolt 13 to fix the first rotating shaft 3.

[0054] In this embodiment, the first rotating shaft 3 is connected to the first block 2 by clamping, which makes the installation and disassembly of the first rotating shaft 3 convenient, and the processing of the parts is also relatively simple. If the first block 2 and the first rotating shaft 3 were to be integrally molded, the resulting structure would be irregular, making the processing difficult.

[0055] In another embodiment, the third clamping port includes a third through hole adapted to the first rotating shaft 3, and a third slit extending from the inner wall of the third through hole to the surface of the first block 2, the third slit being opened along the axial direction of the third through hole;

[0056] A third countersunk hole is provided on the third clamping part located on one side of the third slit. The third countersunk hole extends from the surface of the third clamping part to the inner wall of one side of the third slit. A third threaded hole is provided on the third clamping part located on the other side of the third slit. The third threaded hole is opposite to the third countersunk hole and extends from the inner wall of the other side of the third slit into the interior of the third clamping part.

[0057] Two sets of third countersunk holes and third threaded holes are provided on the two third clamping parts that form the third clamping opening. The third countersunk holes and the third threaded holes opposite to them are set as a set.

[0058] In this embodiment, the two third clamping parts forming the third clamping opening are connected by a third bolt 13. The contact area between the third bolt 13 and the third countersunk hole and the third threaded hole is relatively large, which can better absorb and disperse the vibration in the first block 2, and ensure the stability of the structure as much as possible. At the same time, by opening two sets of third countersunk holes and third threaded holes, and connecting the two third clamping parts forming the third clamping opening with two third bolts 13, the clamping effect of the third clamping opening on the first rotating shaft 3 can be strengthened, ensuring the stability of the contact surface between the first rotating shaft 3 and the third through hole, thereby ensuring the stability of the structure.
