Description

Technical Field

[0001] The utility model relates to the field of slope detection instruments, in particular to a non-contact deflection detector for slope detection. Background Art

[0002] In the field of slope engineering, slope stability testing is crucial. Accurately and promptly acquiring slope deflection information provides a key basis for preventing geological disasters such as slope instability and landslides. Non-contact deflection detection technology has been widely used in slope testing due to its advantages, such as non-interference with the measured object and wide detection range. Traditional slope deflection detection methods primarily rely on contact measurement, such as displacement sensors. These contact measurement methods have limitations. They require sensors to be installed on the slope surface, a complex installation process that can damage the original slope. Long-term exposure to harsh natural environments also makes sensors susceptible to damage, resulting in reduced measurement accuracy and increased maintenance costs.

[0003] Chinese Utility Model Patent Application No. 202222209166.7 proposes a displacement monitoring device for arch bridge pier tops. The device includes a laser sensor and a reflector. A protective cover is provided outside the laser sensor. A window is provided on one horizontal side of the protective cover, and an L-shaped mounting bracket is provided on the bottom surface of the protective cover. The L-shaped bracket is bolted to one side of the bridge pier. The top end surface of the protective cover has a magnetic antenna. The displacement monitoring device of this utility model uses a non-contact measurement method. Compared with the existing photoelectric image measurement method for deflection detection, the laser displacement sensor effectively reduces the impact of the surrounding environment, temperature, and weather on the monitoring data, improves the environmental adaptability of the displacement monitoring device, improves the accuracy of the monitoring results, and reduces the probability of bridge accidents caused by inaccurate data.

[0004] Currently, the existing non-contact deflection testers for slope detection have many limitations and cannot meet the diverse needs of actual detection. The first is that the installation method of the existing non-contact deflection testers is relatively simple, usually equipped with only one fixing method, which is difficult to adapt to slope support structures of different materials and types. When faced with a variety of different slope support structures such as rocks, metal brackets, temporary columns, etc., the existing detectors cannot quickly switch the installation method. If the slope support structure is made of metal, ordinary detectors may not have specially adapted quick adsorption fixing devices, and can only use cumbersome bolt connections and other methods. Not only is the installation process time-consuming and labor-intensive, but it also requires additional tools; and when a tripod is required for high-altitude detection, the existing detector may not be able to quickly connect to the tripod, and often requires complicated installation steps and additional connectors, which greatly reduces the efficiency of instrument deployment and limits the application of the detector in different scenarios.

[0005] The existing deflection detector has great deficiencies in angle adjustment. The main frame body cannot be horizontally rotated, and the non-contact detection lens is difficult to be flexibly adjusted in up-down angle. In actual detection process, the slope terrain is often complex and diverse, and various slope surfaces, corners and irregular areas exist. The existing deflection detector is difficult to realize smooth and continuous fine angle adjustment. Although some devices introduce spring or rubber buffer structure to reduce vibration, the spring or rubber buffer structure is easy to age and has short service life, and cannot provide constant damping force. Therefore, the existing technology has obvious deficiencies in realizing smooth adjustment, accurate positioning and long-term stability of the lens pitch angle. The adjustment smoothness, anti-interference ability and reliable locking function cannot be considered, and it is difficult to adapt to the complex and variable slope monitoring environment.

[0006] In summary, the existing non-contact deflection detector for slope detection has obvious defects in installation flexibility and detection angle adjustment, and cannot meet the complex and variable slope detection requirements. Therefore, the existing technology is improved, and a non-contact deflection detector for slope detection is provided. Content of the utility model

[0008] As a preferred technical scheme of the utility model, the upper part of the detection lens side mounting rack is provided with a handheld handle, and trapezoidal grooves are formed in the two sides of the handheld handle.

[0009] As a preferred technical solution of the present invention, a grip rod mounting seat is provided at the lower portion of the trapezoidal groove, and the grip rod mounting seat is connected to the detection lens side mounting frame by tightening the threaded rod.

[0010] As a preferred technical solution of the present invention, a lens protective cover is provided on the front side of the non-contact deflection detection lens, and the non-contact deflection detection lens is connected to a lens telescopic light-shielding tube.

[0011] As a preferred technical solution of the present invention, a zoom lens is provided on the rear side of the non-contact deflection detection lens.

[0012] As a preferred technical solution of the present invention, a non-contact deflection detection data display component is provided on the main frame.

[0013] As a preferred technical solution of the present invention, the non-contact deflection detection data display component includes a non-contact deflection detection display, and a non-contact deflection detection control button is provided on the side of the non-contact deflection detection display.

[0014] As a preferred technical solution of the present invention, a battery is embedded in the non-contact deflection detection display.

[0015] Compared with the existing technology, the beneficial effects of the present invention are as follows: the instrument of the present invention adopts a modular magnetic mounting base with a standard magnetic interface at the bottom, which is matched with a strong magnet base, a tripod quick-release plate, a suction cup base, and a rock bolt fixing clip to replace the base module. Through dual fixation by magnetism and mechanical slots, it can be quickly switched and installed on a variety of slope support structures such as rocks, metal brackets, and temporary columns, greatly improving the flexibility of instrument deployment. For example, on a slope support structure made of metal, a strong magnet base can be used for rapid adsorption and fixation; when a tripod is needed for high-altitude detection, it can be quickly connected to the tripod by replacing it with a tripod quick-release plate, without the need for complicated installation steps and additional tools. The tripod quick-release interface in the center of the magnetic fixing base of the present invention is convenient for quick connection with the tripod, and the rock bolt socket on the inner side of the edge can be inserted into the rock bolt. When detecting rock slopes, the rock bolts are inserted into the socket and combined with the magnetic effect to firmly fix the instrument.

[0016] This new rotating pan-tilt stand allows for horizontal rotation of the main frame, and the non-contact lens's vertical angle adjustment axis allows for vertical adjustment of the non-contact deflection detection lens. Operators can flexibly adjust the lens's horizontal and vertical orientation based on actual testing needs, allowing for comprehensive inspection of different slope areas from all angles. When inspecting slopes with complex terrain, the lens's rotation and angle adjustment allow for detailed inspection of every surface and corner.

[0017] This utility model connects the lens mounting bracket and the non-contact deflection detection lens with a non-contact upper and lower angle adjustment shaft, enabling flexible adjustment of the lens's pitch angle. When the operator rotates the angle adjustment knob, power is transmitted via the connecting shaft to the magnetic damping sleeve. The embedded magnetic adsorption ring within the sleeve works in conjunction with the bearing to generate a stable damping force, ensuring a smooth adjustment process and effectively avoiding jitter and overshoot. After adjustment is complete, the angle adjustment nut is tightened to lock the structure, preventing angular shift during detection and ensuring measurement stability. Power is further transmitted via a coupling buckle to the guide cone. The spiral groove on the guide cone mates with the adjustment shaft and the embedded cross buckle to precisely convert rotational motion into rotation of the angle adjustment shaft, enabling precise control of the lens angle. This structure adapts to varying slopes and detection heights, ensuring accurate lens alignment and capturing clear images. The overall structure offers stable installation, precise adjustment, and strong anti-interference capabilities, making it particularly suitable for long-term slope monitoring in complex field environments, significantly improving the reliability and practicality of non-contact deflection detection.

The magnetic damping vibration damping sleeve 95 is installed on the sleeve mounting frame 99.

[0032] A handheld grip 10 is located above the detection lens mounting frame 7, with trapezoidal grooves 11 defined on either side. A grip mount 12 is located below the trapezoidal groove 11 and is connected to the detection lens mounting frame 7 via a tightening threaded rod 13. A lens protective hood 81 is located in front of the non-contact deflection detection lens 8, which is connected to a telescopic lens light shielding tube 82.

[0033] A zoom lens 83 is disposed on the rear side of the non-contact deflection detection lens 8. A non-contact deflection detection data display assembly is disposed on the main frame 6. This non-contact deflection detection data display assembly includes a non-contact deflection detection display 14, and a non-contact deflection detection control button 15 is disposed on the side of the non-contact deflection detection display 14. A battery 16 is embedded in the non-contact deflection detection display 14.

[0034] Working principle of the non-contact deflection tester: The bottom of the instrument is designed as a standard magnetic interface, which is compatible with replaceable base modules, such as a strong magnet base, a tripod quick-release plate, a suction cup base, and a rock screw fixing clamp. Each module adopts a dual fixing method of magnetism and mechanical slots. When the instrument needs to be installed on different slope support structures, a strong magnet base can be used on the rock surface to fix the instrument to the rock by the adsorption force of the magnet. At the same time, the mechanical slot further enhances the stability of the fixation; if a tripod is required for installation, it can be replaced with a tripod quick-release plate and connected to the tripod through the tripod quick-release interface 3. This design enables the instrument to be quickly switched and installed on a variety of slope support structures such as rocks, metal brackets, and temporary columns, greatly improving the flexibility of deployment.

[0035] The magnetic mounting base 2 is located below the main unit mounting plate 1. A tripod quick-release port 3 in the center facilitates quick connection to a tripod. Piston holes 4, located on the inner edge, allow for the insertion of rock bolts, further enhancing the instrument's stability on rocky slopes. When the instrument is placed on a slope with rock bolts, inserting the bolts into the holes 4 allows the magnetic attraction to securely secure the instrument to the slope.

[0036] The rotating platform 5 of the present invention is positioned above the mainframe mounting base 1 and connected to the main frame 6. This allows for horizontal rotation of the main frame 6. Rotating the platform 5 adjusts the horizontal orientation of the non-contact deflection detection lens 8 to align it with the slope area to be inspected. Operators can manually rotate the main frame 6 to obtain slope deflection information in different directions, depending on the specific inspection requirements.

[0037] The non-contact detection lens upper and lower angle adjustment rotating shaft 9 of the utility model is located on the inner side of the detection lens side mounting frame 7, connecting the detection lens side mounting frame 7 and the non-contact deflection detection lens 8. The operator turns the angle adjustment knob 97, and the angle adjustment knob 97 drives the magnetic damping vibration reduction sleeve 95 to rotate through the connecting shaft 96. An embedded magnetic adsorption ring 951 is provided in the magnetic damping vibration reduction sleeve 95. The embedded magnetic adsorption ring 951 cooperates with the bearing 952 to provide a certain damping force during the rotation process, making the rotation more stable and reducing the inaccurate angle adjustment caused by external force impact or shaking. At the same time, the magnetic damping vibration reduction sleeve 95 is installed on the shaft sleeve mounting frame 99 to ensure the stability of the entire rotating structure. The angle adjustment tightening nut 98 is used to fix the angle adjustment knob 97 after adjusting the angle to prevent the angle from changing during the detection process.

[0038] The rotation of the magnetic damping vibration reduction sleeve 95 is transmitted to the guide cone 93 through the coupling buckle 94. The guide cone 93 is provided with a spiral groove 931. When the guide cone 93 rotates, the spiral groove 931 guides the corresponding component to produce a corresponding displacement. The rotation of the guide cone 93 is transmitted to the embedded cross buckle 91 through the adjustment rotation shaft 92. The embedded cross buckle 91 is connected to the non-contact detection lens up and down angle adjustment rotation shaft 9. In this way, the rotation of the angle adjustment knob 97 is ultimately converted into the rotation of the non-contact detection lens up and down angle adjustment rotation shaft 9, thereby achieving the up and down angle adjustment of the non-contact deflection detection lens 8. The operator can accurately adjust the up and down angles of the non-contact deflection detection lens 8 according to the actual situation of the slope and the detection requirements to obtain the best detection viewing angle. The operator can adjust the up and down angles of the non-contact deflection detection lens 8 according to the slope of the slope and the height of the detection position to ensure that the lens can accurately align with the detection target and obtain a clear detection image.

[0039] The handheld grip 10 on the upper portion of the detection lens side mounting frame 7 of the present invention facilitates the operator to operate and adjust the instrument by hand. The grip mounting seat 12 is connected to the detection lens side mounting frame 7 by a fastening threaded rod 13, and the operator can fasten the connection by adjusting the fastening threaded rod 13.

[0040] The non-contact deflection detection lens 8 is used to obtain the deflection information of the slope. The lens captures the image of the slope surface and uses image processing and analysis to determine the deflection change of the slope. The lens protective cover 81 set on the front side of the lens can protect the lens from external factors such as dust and rain, thereby extending the service life of the lens. The telescopic light-shielding tube 82 of the lens can be adjusted according to the lighting conditions of the actual detection environment, reducing the interference of external light on the detection results and improving the accuracy of the detection. The zoom lens 83 on the rear side of the lens can adjust the focal length of the detection lens, so that the lens can clearly capture slope areas at different distances, expanding the detection range.

[0041] The non-contact deflection detection data display component set on the frame includes a non-contact deflection detection display 14 and a non-contact deflection detection control button 15. The non-contact deflection detection display 14 is used to display the slope deflection data obtained by the non-contact deflection detection lens 8, so that the operator can intuitively observe the deflection changes of the slope. The non-contact deflection detection control button 15 is used to control various functions of the detector, such as turning on or off the detection function and adjusting the detection parameters. The battery 16 embedded in the non-contact deflection detection display 14 provides power support for the display and other components of the detector to ensure that the instrument can work normally.

[0042] Compared with the traditional contact measurement method, the non-contact deflection detector has obvious advantages. The traditional contact measurement method requires the installation of sensors on the surface of the slope. The installation process is complicated and may cause certain damage to the original state of the slope. However, the non-contact deflection detector does not need to install sensors on the surface of the slope, which avoids damage to the slope. At the same time, the installation process is simpler and faster. In addition, the sensors of the traditional contact measurement method are exposed to harsh natural environments for a long time and are easily damaged, resulting in a decrease in measurement accuracy and an increase in maintenance costs. The non-contact deflection detection lens 8 can avoid direct exposure to harsh environments, reduce the risk of damage, and reduce maintenance costs. Moreover, traditional contact measurement can only obtain deflection information of a limited number of points, and it is difficult to fully and accurately reflect the deflection changes of the entire slope. The non-contact deflection detection lens 8 can obtain more comprehensive deflection information by shooting large-area slope images, and more accurately reflect the deflection changes of the entire slope.

[0043] The non-contact deflection tester operates as follows: Select the mounting module: Depending on the type of slope support structure, choose the appropriate module from the interchangeable base modules: strong magnet base, tripod quick-release plate, suction cup base, and rock bolt clamp. If the test site is on a rock surface, choose the strong magnet base; if a tripod is required, choose the tripod quick-release plate.

[0044] Attach the selected base module to the standard magnetic connector on the bottom of the instrument using both magnetic and mechanical snap-on attachment. If using a tripod, attach the tripod quick-release plate to the tripod via the tripod quick-release connector 3. If working on a rocky slope with pitons, insert the pitons into the piton receptacles 4 on the inner edge of the magnetic base 2 and secure the instrument using the strong magnetic base's suction force.

[0045] Check whether the lens protective cover 81 of the non-contact deflection detection lens 8 is intact and whether the lens telescopic light shielding tube 82 can be extended and retracted normally. Check the non-contact deflection detection data display component to confirm whether the non-contact deflection detection display 14 can display normally and whether the non-contact deflection detection control button 15 can be operated normally. At the same time, check whether the battery 16 embedded in the display has sufficient power.

[0046] By rotating the pan / tilt base 5 and the main frame 6 horizontally, the non-contact deflection detection lens 8 is roughly aligned with the slope area to be inspected. The operator holds the hand grip 10 on the upper portion of the inspection lens side mounting frame 7 and uses the non-contact inspection lens vertical angle adjustment axis 9 to adjust the vertical angle of the non-contact deflection detection lens 8 to accurately align the lens with the inspection target. Fine adjustments can be made based on the slope gradient and the height of the inspection location.

[0047] Press the non-contact deflection detection control button 15 to turn on the detection function of the detector, and set relevant parameters according to actual detection requirements, such as the focal length of the zoom lens 83 and the detection time interval. Adjust the lens telescopic light shielding tube 82 to reduce the interference of external light on the detection results.

[0048] The non-contact deflection detection lens 8 starts to capture images of the slope surface. The lens uses image processing and analysis technology to process the captured image and calculate the deflection change of the slope. During the detection process, the non-contact deflection detection display 14 displays the detected slope deflection data in real time, and the operator can visually observe the deflection change of the slope. Stop detection: After the detection is completed, press the non-contact deflection detection control button 15 to stop the detection function of the detector. If using a tripod, remove the instrument from the tripod; if using other base modules, disconnect the module from the instrument. Keep the replaceable base module properly to avoid damage. Check the various components of the instrument to ensure that they are not damaged or lost, and store the instrument for next use.

Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods.
