Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0027] In view of the problems existing in the prior art in the background technology, the embodiment of the present application provides a bridge monitoring device based on microwave vibration measurement, such as Figure 1 The structure diagram of a bridge monitoring device based on microwave vibration measurement provided by the utility model is illustrated; Figure 2 A partial structural cross-sectional schematic diagram of a bridge monitoring device based on microwave vibration measurement provided by the utility model is illustrated; Figure 3 A partial structural diagram of a bridge monitoring device based on microwave vibration measurement provided by the utility model is illustrated; Figure 4 A partial structural schematic diagram of a bridge monitoring device based on microwave vibration measurement provided by the utility model is illustrated.
[0028] See also Figures 1 to 4 The bridge monitoring device based on microwave vibrometer includes: a tripod 1, an angle adjustment mechanism 2 fixedly connected to the upper end of the tripod 1 and a microwave vibrometer 3 connected to the top of the angle adjustment mechanism 2; the tripod includes supporting legs, a central connecting part fixedly connected to the supporting legs and a central rod; the angle adjustment mechanism 2 includes a horizontal adjustment mechanism 21 fixedly connected to the upper end of the tripod 1 and a swing mechanism 22 fixedly connected to the upper end of the horizontal adjustment mechanism 21; the microwave vibrometer 3 is connected to a mounting part 4 provided on the swing mechanism 22.
[0029] Specifically, the tripod 1 is composed of three equal-length supporting legs 11 and a circular central connecting portion 12. The central connecting portion 12 is fixedly connected with a central rod 13 for adjusting the height of the supporting legs 11. The horizontal adjustment mechanism 21 is arranged at the upper end of the central connecting portion, and is used to control the swing mechanism 22 and the microwave vibrometer 3 installed on the mounting portion 4 at the upper end of the swing mechanism 22 to rotate 30 degrees in the horizontal plane and lock, thereby adjusting the orientation of the microwave vibrometer 3. The swing mechanism 22 is fixedly connected to the upper end of the horizontal adjustment mechanism 21, and is used to control the microwave vibrometer 3 to swing left and right within a certain range and lock the position to meet the monitoring needs of bridges at different heights or angles.
[0030] The microwave vibrometer 3 can select at least one of a bridge deflection microwave vibrometer, a bridge cable tension microwave vibrometer or a bridge multifunctional microwave vibrometer according to actual monitoring needs. The present application does not limit the type of microwave vibrometer 3.
[0031] Optionally, the bottom of the support leg 11 is provided with an anti-skid pad or spikes to increase stability.
[0032] In one implementation, the horizontal adjustment mechanism 21 includes a turntable 211 and a first driver 212 disposed at the center of the lower end of the turntable 211. Specifically, the first driver 212 is disposed at the center of the lower end of the turntable 211 to provide power so that the turntable 211 can rotate around the central axis to achieve horizontal angle adjustment of the microwave vibrometer 3. The first driver 212 can be driven by a motor or hydraulically, and motor drive is more preferred.
[0033] In one implementation, the swing mechanism 22 includes a U-shaped seat 221 fixedly connected to the horizontal adjustment mechanism 21 , a rotating shaft 222 penetrating and connected to a side wall of the U-shaped seat 221 , and a second driver 223 connected to one end of the rotating shaft 222 .
[0034] Specifically, the swing mechanism 22 is fixedly connected to the horizontal adjustment mechanism 21 through its U-shaped seat 221. The design of the U-shaped seat 221 enables it to stably support the rotating shaft 222. The rotating shaft 222 penetrates and connects the side wall of the U-shaped seat 221, providing a rotation center for the swing mechanism. The second driver 223 connected to one end of the rotating shaft 222 is used to provide power so that the rotating shaft 222 and its connected components can swing around the rotating shaft. The second driver 223 can be driven by a motor or a hydraulic drive, and the motor drive is more preferred. By controlling the operation of the second driver 223, the swing angle of the swing mechanism 22 can be accurately adjusted, so that the microwave vibrometer 3 can swing within a certain range in the vertical direction, thereby achieving more complex and accurate spatial angle adjustment, meeting the precise positioning requirements of different monitoring points during bridge monitoring.
[0035] Based on the previous embodiment, in one implementation, the swing mechanism 22 also includes an angle measuring instrument 224 connected to the upper portion of the U-shaped seat 221; the angle measuring instrument 224 includes a pointer 225 and a scale 226 connected to the other end of the rotating shaft 222, and the pointer 225 passes through an opening at the center of the scale 226 to point to the scale.
[0036] Specifically, the pointer 225 is connected to the other end of the rotating shaft 222. When the swing mechanism 22 swings around the rotating shaft 222, the pointer 225 rotates accordingly to indicate the current angle. The scale 226 is a circular scale with precise scales for reading the swing angle of the swing mechanism 22. The angle measuring instrument 224 of this embodiment allows the operator to intuitively read the precise angle information when adjusting the swing mechanism 22, thereby ensuring that the monitoring direction of the microwave vibrometer 3 can be accurately controlled and adjusted.
[0037] Optionally, the scale 226 is made of a transparent acrylic material.
[0038] In one implementation, the mounting portion 4 includes a connecting member 42 fixedly connected to the rotating shaft 222 , and a clamping member 43 and a locking mechanism 44 installed on the upper end of the connecting member 42 , and the locking mechanism 44 passes through openings on both sides of the clamping member 43 to fix the microwave vibrometer 3 .
[0039] Specifically, the locking mechanism 44 may be a bolt, a buckle or other types of fasteners. When installing the microwave vibrometer 3, the microwave vibrometer 3 is first placed in a proper position of the clamp 43, and then fixed by the locking mechanism 44, and its fastening strength is adjusted as needed to adapt to microwave vibrometers of different sizes and weights. The mounting portion provided in this embodiment provides a stable and reliable mounting method, and is easy to operate.
[0040] In one implementation, the bridge monitoring device further includes a communicator 5 disposed on the side of the center pole 13 and a controller connected to the communicator 5 , wherein the communicator 5 is electrically connected to the microwave vibrometer 3 , and the controller is electrically connected to the angle adjustment mechanism 2 .
[0041] Specifically, the communicator 5 is integrated into the tripod 1 and is electrically connected to the microwave vibrometer. During operation, the monitoring data collected by the microwave vibrometer 3 is transmitted to the remote monitoring center or related equipment in real time through the communicator 5. At the same time, the remote monitoring center can also transmit the adjustment instruction to the controller through the communicator 5, thereby controlling the angle adjustment mechanism 2 to adjust the monitoring angle or monitoring frequency, thereby improving the flexibility and convenience of monitoring.
[0042] In one implementation, the bridge monitoring device further includes an angle sensor connected to the horizontal adjustment mechanism 21 .
[0043] Specifically, the angle sensor can be installed on the edge of the turntable 211 or on a fixed structure connected to the rotation center of the turntable 211. When the horizontal adjustment mechanism 21 rotates through the first driver 212, the angle sensor synchronously senses and records the rotation angle of the turntable 211.
[0044] Optionally, the angle sensor may also be electrically connected to the communicator 5 to transmit the rotation angle data of the turntable 211 .
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
