Description

Technical Field

[0001] This utility model relates to the field of visual displacement monitoring technology, specifically to an astronomical telescope support for long-distance visual displacement monitoring. Background Technology

[0002] Computer vision-based displacement measurement technology has made groundbreaking progress in the field of structural health monitoring in recent years. With the deep integration of digital image processing algorithms (such as sub-pixel-level analysis algorithms and feature point matching algorithms) and deep learning technology, vision measurement systems can now achieve micrometer-level displacement resolution. This technology, through its advantages of non-contact measurement, full-field monitoring, and visualized data output, demonstrates unique value in scenarios such as slope geological disaster early warning, dam deformation monitoring, bridge modal analysis, and wind vibration observation of super high-rise buildings. Especially in mid-to-long-range monitoring scenarios ranging from 200 meters to 2000 meters, vision systems offer significant cost and spatial resolution advantages compared to traditional GNSS and total stations.

[0003] In long-distance visual displacement monitoring systems, the performance of the optical imaging unit directly affects the measurement accuracy. According to the principle of visual measurement, the displacement resolution Δ satisfies the relationship between the system focal length f and the pixel size s: Δ = H·s / (f·k) (where H is the object distance and k is the magnification factor). To improve system sensitivity, the use of large-aperture (D≥300mm) and long-focal-length (f≥2000mm) astronomical telescopes has become a technical consensus.

[0004] However, the optical and mechanical structure design of traditional astronomical telescopes is mainly geared towards astronomical observation needs. Their three major characteristics (large aperture, large focal length, and large mass) make it extremely inconvenient to use astronomical telescopes in engineering monitoring scenarios: First, the mass of the primary mirror group exceeds 10 kg, which doubles the torque requirement of the pitch / azimuth adjustment mechanism, and the micro-motion worm gear system of conventional gimbals is difficult to achieve precise pointing at sub-angular levels; Second, the length of the telescope tube is generally long, and the traditional single-point support will form a large lever arm, which will produce a certain degree of angular vibration under the action of wind, seriously restricting the imaging stability under long-distance measurement conditions.

[0005] In summary, there is an urgent need to provide an astronomical telescope support for long-distance visual displacement monitoring in order to solve the problems existing in the prior art. Utility Model Content

[0039] Example

[0040] See Figure 1 This embodiment provides an astronomical telescope support for long-distance visual displacement monitoring, including a transition plate assembly 1, a rotating fulcrum 2, a lifting slide assembly 3, a rotating slide assembly 4, and a base plate 5 arranged sequentially from top to bottom;

[0041] See Figure 2 The adapter plate assembly 1 includes an adapter plate 1.1 and an adapter plate holder 1.2. The adapter plate 1.1 is disposed on the adapter plate holder 1.2. The adapter plate 1.1 is used to place the astronomical telescope, and its upper surface is provided with an arc surface, which matches the arc surface of the astronomical telescope.

[0042] See Figure 3 The adapter plate 1.1 has a slide rail 1.3 along its length on its bottom surface, and the adapter plate retainer 1.2 has a sliding groove, with the slide rail 1.3 matching the sliding groove. The adapter plate retainer 1.2 has a locking assembly 1.4 on its side for locking the adapter plate 1.1 and the adapter plate retainer 1.2. The locking assembly 1.4 uses a screw with a knob, which is threadedly connected to the adapter plate retainer 1.2. In this embodiment, preferably, two slide rails 1.3 are provided, and the two slide rails 1.3 are symmetrically inclined. During installation, the slide rail on the bottom surface of the adapter plate 1.1 slides horizontally into the sliding groove. After installation, the locking assembly 1.4 is tightened to achieve relative fixation between the adapter plate 1.1 and the adapter plate retainer 1.2.

[0043] See Figure 1The adapter plate assembly 1 is hinged to the lifting slide assembly 3 via a rotation fulcrum 2; two sets of rotation fulcrum 2 are provided, spaced apart along the length of the adapter plate assembly 1; preferably, the two sets of rotation fulcrum 2 are symmetrically arranged with respect to the centerline of the adapter plate 1.1.

[0044] The lifting slide assembly 3 is provided in two sets, and the lifting slide assembly 3 is provided in a one-to-one correspondence with the rotation fulcrum 2. The rotation fulcrum 2 and the lifting slide assembly 3 are used to adjust the height and pitch angle of the adapter plate assembly 1.

[0045] For details, see Figure 1 The rotating fulcrum 2 includes a rotating connector 2.1 and a fixed base 2.2. The rotating connector 2.1 is fixedly connected to the bottom surface of the adapter plate holder 1.2 by bolts, and the fixed base 2.2 is fixedly connected to the lifting slide assembly 3 by bolts. A rotating shaft is provided on the rotating connector 2.1, and the rotating shaft is rotatably connected to the fixed base 2.2. The axis of the rotating shaft is perpendicular to the length direction of the adapter plate 1.1. A locking component 2.3 for locking the rotating connector 2.1 and the fixed base 2.2 is provided on the fixed base 2.2. In this embodiment, the locking component 2.3 is a locking screw, which is threadedly connected to the fixed base 2.2. After the locking screw is tightened, it abuts against the rotating shaft to achieve locking between the rotating connector 2.1 and the fixed base 2.2.

[0046] See Figure 4 The lifting slide assembly 3 includes an upper connecting plate 3.1, a support assembly 3.2, a lower connecting plate 3.3, and a driving component 3.4. The upper connecting plate 3.1 is connected to the fixed base 2.2, and the lower connecting plate 3.3 is connected to the rotating slide assembly 4 through a fixed plate 6. The support assembly 3.2 is disposed between the upper connecting plate 3.1 and the lower connecting plate 3.3. The driving component 3.4 is connected to the support assembly 3.2 and is used to drive the support assembly 3.2 to unfold and retract.

[0047] In this embodiment, the support assembly 3.2 includes two sets of support rod assemblies arranged opposite each other, connected by a connecting rod; each support rod assembly includes two support rods that are cross-shaped and hinged together, with the hinge point being the cross intersection point, and the two ends of the two support rods are respectively hinged to the upper connecting plate 3.1 and the lower connecting plate 3.3; see also Figure 4In this embodiment, the driving component 3.4 is a lead screw with a knob. The lead screw is threaded to the side of the upper connecting plate 3.1. The end of the lead screw without a knob is connected to the connecting rod between two hinge points on the upper left side. By screwing the lead screw in and out, the two sets of support rod assemblies can be expanded and contracted, thereby achieving lifting and lowering adjustment. Preferably, it also includes a locking component 3.5, which is a locking screw. When locking is required, the locking screw is tightened and abuts against the lead screw to prevent the lead screw from rotating and ensure the stability of the lifting slide assembly 3.

[0048] By adjusting the lifting height of the two sets of lifting slide assemblies 3, the height and pitch angle of the adapter plate 1.1 can be adjusted, thereby enabling the adjustment of the height and pitch angle of the astronomical telescope. The dual-support design significantly improves the stability of the astronomical telescope in the pitch direction. In this embodiment, taking a 438mm adapter plate as an example, the distance between the central axes of the two sets of rotating support points 2 is 243mm, the lifting adjustment stroke of the lifting slide assembly 3 is 60mm, and the pitch angle adjustment range is ±13.9°.

[0049] See Figure 1 and Figure 5 The rotary slide assembly 4 is connected between the lifting slide assembly 3 and the base plate 5, and is used to realize the overall horizontal angle adjustment of the adapter plate assembly 1, the rotating fulcrum 2 and the lifting slide assembly 3. The rotary slide assembly 4 includes an upper connecting member 4.1, a lower connecting member 4.2 and a rotation adjustment assembly 4.3. The upper connecting member 4.1 is fixedly connected to the fixed plate 6, and the lower connecting member 4.2 is fixedly connected to the base plate 5. The upper connecting member 4.1 and the lower connecting member 4.2 are rotatably connected by bearings. Specifically, a central shaft is vertically arranged at the center of the lower connecting member 4.2, and a bearing is sleeved on the central shaft. A through hole is provided at the center of the upper connecting member 4.1, and the through hole matches the outer ring of the bearing.

[0050] See Figure 5 The upper connecting member 4.1 includes an upper connecting member 4.1.1 and an upper connecting member 4.1.2 that are rotatably arranged from top to bottom (both upper connecting members 4.1.1 and 4.1.2 are rotatably connected to the central shaft via bearings). The upper connecting member 4.1.1 is fixedly connected to the lifting slide assembly 3 by bolts. The upper connecting member 4.1.1 is provided with a coarse adjustment lever 4.4, and the upper connecting member 4.1.2 is provided with a fine adjustment lever 4.5. The rotation adjustment assembly 4.3 is disposed on the lower connecting member 4.2 and connected to the fine adjustment lever 4.5.

[0051] It also includes a locking component 4.6, which is disposed on the lower connector 4.2 and cooperates with the rotation adjustment component 4.3 to achieve locking between the upper connector 4.1.2 and the lower connector 4.2.

[0052] In this embodiment, the rotary adjustment component 4.3 includes a lead screw with a knob. The lead screw is mounted on the lower connector 4.2 via a mounting base. The end of the lead screw without a knob is connected to the fine adjustment lever 4.5. The locking component 4.6 uses a locking screw. The locking screw is threaded onto the mounting base and is positioned opposite to the lead screw. When the locking screw is tightened, it abuts against the side of the fine adjustment lever 4.5 opposite to the lead screw, thereby locking the upper connector 4.1.2 and the lower connector 4.2.

[0053] In practical use, first, the rotation direction (i.e., the horizontal rotation angle) is coarsely adjusted by moving the coarse adjustment lever 4.4; after coarse adjustment, the upper connecting parts 4.1.1 and 4.1.2 are locked with locking screws to prevent relative rotation between them; then, the rotation direction is finely adjusted by rotating adjustment assembly 4.3; after fine adjustment, the rotation is locked by locking assembly 4.6 to prevent rotation and ensure the stability of the rotary slide assembly 4 during measurement.

[0054] The base plate 5 is fixedly connected to the lower connecting piece 4.2. When in use, the bracket can be installed on the pier or tripod at the measurement site through the base plate 5.

[0055] In this embodiment, the driving component 3.4 in the lifting slide assembly 3 and the rotation adjustment component 4.3 in the rotating slide assembly 4 both adopt a lead screw structure, which can achieve fine adjustment, and the adjustment accuracy can reach ±0.1mm.

[0056] In this embodiment, by setting locking component 1.4, locking component 2.3, locking component 3.5, and locking component 4.6, the stability of the astronomical telescope during the measurement process can be effectively guaranteed, ensuring imaging quality and accuracy.

[0057] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
