Abstract
Description
Technical Field
[0001] This invention relates to the field of bridge monitoring technology, specifically to an easily adjustable bridge micro-deformation monitoring device and its usage method. Background Technology
[0002] Bridges are an important component of public transportation, a crucial link in highway and railway networks, and a vital artery for ensuring the smooth flow of traffic along roads. As an important transportation facility, bridges play a fundamental role in guaranteeing and promoting socio-economic development. However, when bridges have been in use for too long, aging can pose serious safety hazards, making bridge safety monitoring extremely important. Deformation monitoring is an important part of bridge safety monitoring.
[0003] Chinese patent CN211698186U proposes a component including a support rod, an adjustment assembly, and an installation assembly. The adjustment assembly is fixed to the top of the support rod, and the installation assembly is installed through the inner side of the lower part of the support rod. The adjustment assembly includes a thread, a connecting column, a support frame, a first movable pin, a radar monitor body, an electric telescopic rod, a second movable pin, a slider, and a slide groove. The top of the support rod is connected to the connecting column by a threaded connection. The support frame is welded to the outer side of the top of the connecting column. The radar monitor body is installed on one side of the top of the support frame through the first movable pin. The electric telescopic rod is installed inside the connecting column through the top of the support frame. The top of the electric telescopic rod is connected to the slider through the second movable pin.
[0004] However, the aforementioned patent can only adjust the elevation angle when monitoring bridges, which means that the monitoring device can only monitor the elevation of one part of the bridge and cannot monitor the lateral direction of the bridge. Therefore, multiple sets of monitoring devices are required, which increases the cost.
[0005] Based on this, the present invention designs an easily adjustable bridge micro-deformation monitoring device and its usage method to solve the above problems. Summary of the Invention
[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a bridge micro-deformation monitoring device that is easy to adjust and a method of using it.
[0007] To achieve the above objectives, the present invention provides the following technical solution:
[0008] An easily adjustable bridge micro-deformation monitoring device, including a mounting bucket;
[0009] An orientation-adjustable scanning component capable of switching to any orientation and monitoring any direction is fixedly connected to the middle of the mounting bucket.
[0010] Three sets of adjustable brackets for supporting and leveling the installation bucket are fixedly connected at equal intervals to the bottom outer end of the installation bucket.
[0011] The orientation-adjustable scanning assembly includes a left-right swing adjustment assembly, a self-rotating scanning assembly, and a blocking assembly. The left-right swing adjustment assembly is fixedly connected to the middle of the bottom plate of the mounting barrel. The left-right swing adjustment assembly passes through the bottom plate of the mounting barrel. The self-rotating scanning assembly is connected to the upper end of the left-right swing adjustment assembly. The blocking assembly is fixedly connected to the top of the mounting barrel.
[0012] Furthermore, the left-right swing adjustment component includes a forward and reverse motor, a drive gear, a support vertical plate, and a driven gear. A set of forward and reverse motors is fixedly connected to both the front and rear ends of the bottom of the mounting barrel. The output ends of the forward and reverse motors pass through the bottom plate of the mounting barrel and are fixedly connected to the drive gear. A support vertical plate is fixedly connected to the bottom of the mounting barrel between the two sets of forward and reverse motors. A set of driven gears is rotatably connected to the front and rear side walls of the upper end of the support vertical plate through a rotating shaft. The lower ends of the two sets of driven gears, on opposite sides, are meshed with the adjacent drive gear.
[0013] Furthermore, the self-rotating scanning assembly includes an n-shaped support frame, a rotating gear, an L-shaped rotating column, and a scanning device. The lower ends of the front and rear inner walls of the n-shaped support frame are rotatably connected to the center of the side walls of two sets of driven gears that are far apart from each other via rotating shafts. The L-shaped rotating column passes through the middle of the top plate of the n-shaped support frame and is rotatably connected to the n-shaped support frame via a bearing. The bottom of the L-shaped rotating column is fixedly connected to the rotating gear, which is located between the upper ends of the two sets of driven gears, and both the front and rear ends of the rotating gear are meshed with the end of a set of driven gears close to the rotating gear. The left end of the crossbar of the L-shaped rotating column is fixedly connected to the scanning device.
[0014] Furthermore, the adjustable bracket includes a first hinge seat, a threaded rod, a slide tube, a threaded rotating tube, a second hinge seat, and a support pad. Three sets of first hinge seats are fixedly connected at equal intervals to the bottom of the mounting bucket. A set of threaded rods is rotatably connected to the lower end of each first hinge seat. The lower end of the threaded rod passes through the threaded rotating tube and is inserted into the slide tube. The threaded rod is slidably connected to the slide tube. The threaded rod is threadedly connected to the upper end of the threaded rotating tube. The lower end of the threaded rotating tube is rotatably connected to the slide tube. A second hinge seat is fixedly connected to the bottom of the slide tube. A support pad is rotatably connected to the bottom of the second hinge seat.
[0015] Furthermore, the bottom of the installation bucket is fixedly connected to a self-alarming level monitoring component that monitors whether the installation bucket is level and automatically issues an alarm when it is not level.
[0016] Furthermore, the self-alarming horizontal monitoring component includes a shielding sleeve, an upper conductive metal plate, a lower conductive metal plate, a conductive column, an alarm, a conductive wire, a metal ball, and a groove. The shielding sleeve is fixedly connected to the bottom of the mounting barrel. The upper conductive metal plate is fixedly connected to the inner wall of the upper end of the shielding sleeve. The lower conductive metal plate is fixedly connected to the bottom of the shielding sleeve. A conductive column is fixedly connected between the outer ends of the upper and lower conductive metal plates. A power supply is fixedly connected to the middle of the conductive column. An alarm is fixedly connected to the top of the upper conductive metal plate. A conductive wire is fixedly connected to the middle position of the bottom of the upper conductive metal plate. A metal ball is fixedly connected to the bottom of the conductive wire. A groove is formed on the lower conductive metal plate below the metal ball, and the lower end of the metal ball is inside the groove.
[0017] Furthermore, the bottom plate of the mounting bucket is parallel to the upper conductive metal plate and the lower conductive metal plate.
[0018] This application also provides a method for using an easily adjustable bridge micro-deformation monitoring device, the specific steps of which are as follows:
[0019] Step 1: Rotate the threaded tube. The threaded tube rotates under the limit of the slide tube, which causes the threaded tube to drive the threaded rod to slide away from the slide tube. This causes the threaded rod to lift one end of the mounting bucket upward through the first hinge seat. By adjusting the length of the threaded rod of all adjustable brackets protruding from the slide tube, the height of each part of the mounting bucket can be adjusted, thus allowing the mounting bucket to be leveled.
[0020] Step Two: When the installation bucket is horizontal, the metal ball, under the influence of gravity, pulls the conductive wire, keeping it vertical and the lower end of the metal ball inside the groove. When the installation bucket is not horizontal, it causes the lower conductive metal plate and the metal ball to shift within the groove, making the metal ball contact the groove. At this point, a closed circuit is formed by the upper conductive metal plate, the conductive wire, the metal ball, the lower conductive metal plate, and the conductive post, energizing the alarm and triggering it. When the installation bucket is horizontal, the upper and lower conductive metal plates are also horizontal, and the lower end of the metal ball is inside the groove but not in contact with it, thus breaking the circuit and stopping the alarm. This completes the horizontal adjustment of the installation bucket.
[0021] Step 3: After the bucket is leveled and the scanning device needs to be adjusted, start the two sets of forward and reverse motors. Adjust the two sets of motors so that they rotate in opposite directions. The outputs of the two sets of motors drive the two sets of drive gears to rotate in opposite directions. This causes the two sets of drive gears to drive the two sets of driven gears to rotate in the same direction under the support of the vertical support plate. This causes the two sets of driven gears to drive the rotating gears to oscillate left and right around the center of the driven gear. The rotating gear drives the L-shaped rotating column and the N-shaped support frame to oscillate left and right around the center of the driven gear. The L-shaped rotating column oscillates left and right in the slide groove, and the L-shaped rotating column drives the scanning device to oscillate left and right around the center of the driven gear. The system allows for adjustment of the scanning device's height and orientation. When the scanning device is aligned with the object to be monitored, the two sets of forward and reverse motors are adjusted to rotate in the same direction. This causes the outputs of the two sets of forward and reverse motors to drive the two sets of drive gears to rotate in the same direction. Consequently, the two sets of drive gears drive the two sets of driven gears to rotate in opposite directions. This causes the two sets of driven gears to drive the rotating gears to rotate in place under the support and limit of the n-shaped support frame. The rotating gears drive the L-shaped rotating column vertical rod to rotate, which in turn causes the L-shaped rotating column to drive the scanning device to rotate around the L-shaped rotating column vertical rod. This allows the L-shaped rotating column to drive the scanning device to rotate from one end of the object to be monitored to the other end.
[0022] Beneficial effects
[0023] When the installation bucket is leveled and the orientation of the scanning device needs adjustment, the invention activates two sets of forward and reverse motors. These motors are then adjusted to rotate in opposite directions, causing the outputs of the two sets of motors to drive two sets of drive gears in opposite directions. This, in turn, causes the two sets of drive gears to drive two sets of driven gears to rotate in the same direction under the support of the vertical support plate. This causes the two sets of driven gears to drive a rotating gear to oscillate left and right around its center. The rotating gear then drives an L-shaped rotating column and an n-shaped support frame to oscillate left and right around the center of the driven gear. The L-shaped rotating column oscillates left and right in the slide groove, and in turn, drives the scanning device to oscillate left and right around the center of the driven gear. This achieves adjustment of the scanning device's height and orientation. When the scanning device is aligned with the object to be monitored, the two sets of forward and reverse motors are adjusted to rotate... The two sets of forward and reverse motors drive the two sets of drive gears to rotate in the same direction, which in turn drives the two sets of driven gears to rotate in opposite directions. This causes the driven gears to rotate in place under the support and limit of the n-shaped support frame. The rotating gears then drive the L-shaped rotating column to rotate, which in turn causes the L-shaped rotating column to rotate around the vertical rod. This allows the scanning device to rotate from one end of the item to be monitored to the other, thus achieving full monitoring of the item. Since the L-shaped rotating column can rotate the scanning device a full circle, it can monitor items from all directions. The components are protected by cover covers, and the sliding grooves prevent the L-shaped rotating column from swinging unaffected.
[0024] When the mounting bucket needs to be leveled, this invention involves rotating the threaded rotating tube. The rotating tube rotates under the limit of the sliding tube, causing the threaded rod to slide away from the sliding tube. This causes the threaded rod to lift one end of the mounting bucket upwards via the first hinge seat. By adjusting the length of the threaded rods protruding from the sliding tube of all adjustable brackets, the height of various parts of the mounting bucket can be adjusted, thus achieving leveling of the mounting bucket. Because the support pad and the second hinge seat are rotatably connected, the bottom of the support pad can contact the ground at various slopes, resulting in a larger support area and improved stability. Furthermore, when the mounting bucket is level, the metal ball, under the influence of gravity, pulls the conductive wire, keeping the conductive wire vertical. The lower end of the ball is located inside the groove. When the mounting bucket is not horizontal, the mounting bucket causes the lower conductive metal plate and the lower conductive metal plate to become non-horizontal, thus causing the metal ball to shift inside the groove and contact the groove. At this time, a closed circuit is formed through the upper conductive metal plate, conductive wire, metal ball, lower conductive metal plate and conductive post, which enables the power supply to the alarm and triggers the alarm. When the mounting bucket is horizontal, the upper conductive metal plate and the lower conductive metal plate are also horizontal, and the lower end of the metal ball is located inside the groove and does not contact the groove, thus breaking the circuit and stopping the alarm. This completes the horizontal adjustment of the mounting bucket, allowing for immediate detection when the device is not horizontal, thus preventing measurement data errors due to the device not being horizontal.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0035] The present invention will be further described below with reference to embodiments. Example
[0036] Please refer to the instruction manual appendix. Figure 1-7 A bridge micro-deformation monitoring device that is easy to adjust, including a mounting bucket 1.
[0037] An orientation-adjustable scanning component 2, capable of switching to any orientation and monitoring any direction, is fixedly connected to the middle of the mounting bucket 1;
[0038] Three sets of adjustable brackets 3 are fixedly connected at equal intervals to the bottom outer end of the mounting bucket 1 for supporting the mounting bucket 1 and adjusting its level.
[0039] The bottom of the installation bucket 1 is fixedly connected to a self-alarming level monitoring component 4, which is used to monitor whether the installation bucket 1 is level and automatically issue an alarm when it is not level.
[0040] The orientation-adjustable scanning component 2 includes a left-right swing adjustment component 21, a self-rotating scanning component 22, and a blocking component 23. The left-right swing adjustment component 21 is fixedly connected to the middle of the bottom plate of the mounting barrel 1. The left-right swing adjustment component 21 passes through the bottom plate of the mounting barrel 1. The upper end of the left-right swing adjustment component 21 is connected to the self-rotating scanning component 22. The top of the mounting barrel 1 is fixedly connected to the blocking component 23.
[0041] The left-right swing adjustment component 21 includes a forward and reverse motor 211, a drive gear 212, a support vertical plate 213, and a driven gear 214. A set of forward and reverse motors 211 are fixedly connected to the bottom front and rear ends of the mounting barrel 1. The output ends of the forward and reverse motors 211 pass through the bottom plate of the mounting barrel 1 and are fixedly connected to the drive gear 212. A support vertical plate 213 is fixedly connected to the bottom of the mounting barrel 1 between the two sets of forward and reverse motors 211. A set of driven gears 214 are rotatably connected to the front and rear side walls of the upper end of the support vertical plate 213 through a rotating shaft. The lower ends of the two sets of driven gears 214 are meshed with the adjacent drive gear 212 on the side that is far apart from each other.
[0042] The rotating scanning assembly 22 includes an n-shaped support frame 221, a rotating gear 222, an L-shaped rotating column 223, and a scanning device 224. The lower ends of the front and rear inner walls of the n-shaped support frame 221 are rotatably connected to the center of the side walls of two sets of driven gears 214 that are far apart from each other via rotating shafts. The L-shaped rotating column 223 passes through the middle of the top plate of the n-shaped support frame 221 and is rotatably connected to the n-shaped support frame 221 via bearings. The rotating gear 222 is fixedly connected to the bottom of the L-shaped rotating column 223. The rotating gear 222 is located between the upper ends of the two sets of driven gears 214, and both the front and rear ends of the rotating gear 222 are meshed with the end of a set of driven gears 214 that is close to the rotating gear 222. The scanning device 224 is fixedly connected to the left end of the crossbar of the L-shaped rotating column 223.
[0043] The shielding assembly 23 includes a shielding cover 231 and a slide 232. The shielding cover 231 is fixedly connected to the top of the mounting barrel 1. The slide 232 is opened in the middle of the shielding cover 231. The L-shaped rotating column 223 passes through the slide 232 and swings in the slide 232.
[0044] When the installation bucket 1 is leveled and the orientation of the scanning device 224 needs to be adjusted, start the two sets of forward and reverse motors 211. At this time, adjust the two sets of forward and reverse motors 211 so that they rotate in opposite directions. The output ends of the two sets of forward and reverse motors 211 drive the two sets of driving gears 212 to rotate in opposite directions. This causes the two sets of driving gears 212 to drive the two sets of driven gears 214 to rotate in the same direction under the support of the vertical support plate 213. This causes the two sets of driven gears 214 to drive the rotating gear. The rotating gear 222 oscillates left and right around the center of the driven gear 214. The rotating gear 222 drives the L-shaped rotating column 223 and the n-shaped support frame 221 to oscillate left and right around the center of the driven gear 214. The L-shaped rotating column 223 oscillates left and right in the slide groove 232. The L-shaped rotating column 223 drives the scanning device 224 to oscillate left and right around the center of the driven gear 214, thereby adjusting the height and orientation of the scanning device 224. When the scanning device 224 is aligned with the object to be monitored, the two sets of forward and reverse rotating motors 211 are adjusted to make the two sets of forward and reverse rotating motors... The rotating motors 211 rotate in the same direction, causing the outputs of the two sets of forward and reverse rotating motors 211 to drive the two sets of driving gears 212 to rotate in the same direction. This causes the two sets of driving gears 212 to drive the two sets of driven gears 214 to rotate in opposite directions. This causes the two sets of driven gears 214 to drive the rotating gear 222 to rotate in place under the support and limit of the n-shaped support frame 221. The rotating gear 222 drives the vertical rod of the L-shaped rotating column 223 to rotate, which in turn causes the scanning device 224 to rotate around the vertical rod of the L-shaped rotating column 223. This allows the scanning device 224 to rotate from one end of the item to be monitored to the other end, thus achieving the monitoring of the entire item. Since the scanning device 224 can rotate one full turn, it can monitor items in all directions. The components are protected by the cover 231, and the oscillation of the L-shaped rotating column 223 is not affected by the slide groove 232.
[0045] The adjustable bracket 3 includes a first hinge seat 31, a threaded rod 32, a slide tube 33, a threaded rotating tube 34, a second hinge seat 35, and a support pad 36. Three sets of first hinge seats 31 are fixedly connected at equal intervals to the bottom of the mounting bucket 1. A set of threaded rods 32 are rotatably connected to the lower end of each first hinge seat 31. The lower end of the threaded rod 32 passes through the threaded rotating tube 34 and is inserted into the slide tube 33. The threaded rod 32 is slidably connected to the slide tube 33. The threaded rod 32 is threadedly connected to the upper end of the threaded rotating tube 34. The lower end of the threaded rotating tube 34 is rotatably connected to the slide tube 33. The bottom of the slide tube 33 is fixedly connected to a second hinge seat 35. The bottom of the second hinge seat 35 is rotatably connected to a support pad 36.
[0046] When the mounting bucket 1 needs to be leveled, the threaded rotating tube 34 is rotated. The threaded rotating tube 34 rotates under the limit of the sliding tube 33, thereby causing the threaded rotating tube 34 to drive the threaded rod 32 to slide away from the sliding tube 33. This causes the threaded rod 32 to lift one end of the mounting bucket 1 through the first hinge seat 31. By adjusting the length of the threaded rod 32 of all adjustable brackets 3 protruding from the sliding tube 33, the height of each part of the mounting bucket 1 can be adjusted, thereby achieving the leveling of the mounting bucket 1. Since the support pad 36 and the second hinge seat 35 are rotatably connected, the bottom of the support pad 36 can contact the ground at various slopes, resulting in a larger support area and thus improving stability. Example
[0047] Based on Example 1, such as Figure 1-6 As shown, in a preferred embodiment of the present invention, the self-alarming horizontal monitoring component 4 includes a shielding sleeve 41, an upper conductive metal plate 42, a lower conductive metal plate 43, a conductive column 44, an alarm 45, a conductive wire 46, a metal ball 47, and a groove 48. The bottom of the mounting barrel 1 is fixedly connected to the shielding sleeve 41. The upper conductive metal plate 42 is fixedly connected to the inner wall of the upper end of the shielding sleeve 41. The bottom of the shielding sleeve 41 is fixedly connected to the lower conductive metal plate 43. The outer ends of the upper conductive metal plate 42 and the lower conductive metal plate 43 are fixedly connected to the conductive column 44. A power supply is fixedly connected to the middle of the conductive column 44. The top of the upper conductive metal plate 42 is fixedly connected to the alarm 45. The bottom middle position of the upper conductive metal plate 42 is fixedly connected to the conductive wire 46. The bottom of the conductive wire 46 is fixedly connected to the metal ball 47. A groove 48 is opened on the lower conductive metal plate 43 below the metal ball 47. The lower end of the metal ball 47 is inside the groove 48.
[0048] Preferably, the bottom plate of the mounting bucket 1 is parallel to the upper conductive metal plate 42 and the lower conductive metal plate 43;
[0049] When the mounting bucket 1 is horizontal, the metal ball 47, under the influence of gravity, pulls the conductive wire 46, causing the conductive wire 46 to be vertical and the lower end of the metal ball 47 to be inside the groove 48. When the mounting bucket 1 is not horizontal, it causes the lower conductive metal plate 43 to become non-horizontal, resulting in the metal ball 47 shifting inside the groove 48 and contacting it. At this time, the upper conductive metal plate 42, conductive wire 46, metal ball 47, and lower conductive metal plate 43... The conductive post 44 forms a closed circuit, which allows the power supply to energize the alarm 45 and trigger an alarm. When the mounting bucket 1 is in a horizontal state, the upper conductive metal plate 42 and the lower conductive metal plate 43 are also in a horizontal state. The lower end of the metal ball 47 is located inside the groove 48 and does not contact the groove 48, thus breaking the circuit and preventing the alarm 45 from triggering an alarm. At this time, the horizontal adjustment of the mounting bucket 1 is completed, so that it can be known immediately if the device is not horizontal, thus preventing the occurrence of measurement data errors due to the device not being horizontal. Example
[0050] Please refer to the instruction manual appendix. Figure 1-7 The following are the specific steps for using an easily adjustable bridge micro-deformation monitoring device:
[0051] Step 1: Rotate the threaded tube 34. The threaded tube 34 rotates under the limit of the slide tube 33, thereby causing the threaded tube 34 to drive the threaded rod 32 to slide away from the slide tube 33. This causes the threaded rod 32 to lift one end of the mounting barrel 1 through the first hinge seat 31. By adjusting the length of the threaded rod 32 of all adjustable brackets 3 protruding from the slide tube 33, the height of each part of the mounting barrel 1 can be adjusted, thereby allowing the mounting barrel 1 to be horizontally adjusted.
[0052] Step 2: When the installation bucket 1 is horizontal, the metal ball 47 pulls the conductive wire 46 vertically under the influence of gravity, and the lower end of the metal ball 47 is located inside the groove 48. When the installation bucket 1 is not horizontal, the installation bucket 1 causes the lower conductive metal plate 43 to become non-horizontal, thus causing the metal ball 47 to shift inside the groove 48, making the metal ball 47 contact the groove 48. At this time, a closed circuit is formed by the upper conductive metal plate 42, the conductive wire 46, the metal ball 47, the lower conductive metal plate 43, and the conductive post 44, thereby energizing the alarm 45 and triggering an alarm. When the installation bucket 1 is horizontal, the upper conductive metal plate 42 and the lower conductive metal plate 43 are also horizontal, and the lower end of the metal ball 47 is located inside the groove 48 but does not contact the groove 48, thus breaking the circuit and causing the alarm 45 to stop triggering an alarm. At this time, the horizontal adjustment of the installation bucket 1 is completed.
[0053] Step 3: After the installation bucket 1 is leveled and the orientation of the scanning device 224 needs to be adjusted, start the two sets of forward and reverse motors 211. At this time, adjust the two sets of forward and reverse motors 211 so that they rotate in opposite directions. The output ends of the two sets of forward and reverse motors 211 drive the two sets of driving gears 212 to rotate in opposite directions. This causes the two sets of driving gears 212 to drive the two sets of driven gears 214 to rotate in the same direction under the support of the support plate 213. This causes the two sets of driven gears 214 to drive the rotating gear 222 to swing left and right around the center of the driven gear 214. The rotating gear 222 drives the L-shaped rotating column 223 and the n-shaped support frame 221 to swing left and right around the center of the driven gear 214. The L-shaped rotating column 223 swings left and right in the slide groove 232. The L-shaped rotating column 223 drives the scanning device 224 to swing left and right around the center of the driven gear 214. The oscillation allows for adjustment of the height and orientation of the scanning device 224. When the scanning device 224 is aligned with the object to be monitored, the two sets of forward and reverse motors 211 are adjusted so that they rotate in the same direction. This causes the outputs of the two sets of forward and reverse motors 211 to drive the two sets of drive gears 212 to rotate in the same direction. Consequently, the two sets of drive gears 212 drive the two sets of driven gears 214 to rotate in opposite directions. This causes the two sets of driven gears 214 to drive the rotating gear 222 to rotate in place under the support and limit of the n-shaped support frame 221. The rotating gear 222 drives the vertical rod of the L-shaped rotating column 223 to rotate. This causes the L-shaped rotating column 223 to drive the scanning device 224 to rotate around the vertical rod of the L-shaped rotating column 223.

5. The easily adjustable bridge micro-deformation monitoring device of claim 4, wherein, The bottom plate of the mounting bucket (1) is parallel to the upper conductive metal plate (42) and the lower conductive metal plate (43).
6. A method of using the bridge micro-deformation monitoring apparatus of claim 4 or 5, wherein: The specific steps are as follows: Step 1: Rotate the threaded tube (34). The threaded tube (34) rotates under the limit of the slide tube (33), thereby causing the threaded tube (34) to drive the threaded rod (32) to slide away from the slide tube (33). This causes the threaded rod (32) to lift one end of the mounting bucket (1) upward through the first hinge seat (31). By adjusting the length of the threaded rod (32) of all the adjustable brackets (3) protruding from the slide tube (33), the height of each part of the mounting bucket (1) can be adjusted, thereby allowing the mounting bucket (1) to be horizontally adjusted. Step 2: When the installation bucket (1) is horizontal, the metal ball (47) pulls the conductive wire (46) under gravity, making the conductive wire (46) vertical and the lower end of the metal ball (47) inside the groove (48). When the installation bucket (1) is not horizontal, the installation bucket (1) causes the lower conductive metal plate (43) and the lower conductive metal plate (43) to be non-horizontal, thereby causing the metal ball (47) to shift inside the groove (48), so that the metal ball (47) contacts the groove (48). At this time, the upper conductive wire... The electric metal plate (42), conductive wire (46), metal ball (47), lower conductive metal plate (43) and conductive column (44) form a closed circuit, thereby energizing the alarm (45) and causing it to sound an alarm. When the mounting bucket (1) is in a horizontal state, the upper conductive metal plate (42) and the lower conductive metal plate (43) are also in a horizontal state. The lower end of the metal ball (47) is located inside the groove (48) and does not contact the groove (48), thereby breaking the circuit and causing the alarm (45) to stop sounding an alarm. At this time, the horizontal adjustment of the mounting bucket (1) is completed. Step 3: When the installation bucket (1) is leveled and the orientation of the scanning device (224) needs to be adjusted, start the two sets of forward and reverse motors (211). At this time, adjust the two sets of forward and reverse motors (211) so that the forward and reverse motors (211) rotate in opposite directions. The output ends of the two sets of forward and reverse motors (211) drive the two sets of driving gears (212) to rotate in opposite directions, so that the two sets of driving gears (212) drive the two sets of driven gears (214) on the support vertical plate (213). Supported by the two gears, they rotate in the same direction, causing the two driven gears (214) to drive the rotating gear (222) to swing left and right around the center of the driven gear (214). The rotating gear (222) drives the L-shaped rotating column (223) and the n-shaped support frame (221) to swing left and right around the center of the driven gear (214). The L-shaped rotating column (223) swings left and right in the slide groove (232). The L-shaped rotating column (223) drives the scanning device (224) to rotate around the driven gear (214). The center swings left and right, thereby adjusting the height and orientation of the scanning device (224). When the scanning device (224) is aligned with the object to be monitored, the two sets of forward and reverse motors (211) are adjusted so that the two sets of forward and reverse motors (211) rotate in the same direction. This causes the output ends of the two sets of forward and reverse motors (211) to drive the two sets of drive gears (212) to rotate in the same direction. This causes the two sets of drive gears (212) to drive the two sets of driven gears (214) in opposite directions. The rotation causes the two driven gears (214) to drive the self-rotating gear (222) to rotate in place under the support and limit of the n-shaped support frame (221). The self-rotating gear (222) drives the vertical rod of the L-shaped rotating column (223) to rotate, thereby causing the L-shaped rotating column (223) to drive the scanning device (224) to rotate around the vertical rod of the L-shaped rotating column (223), thereby causing the L-shaped rotating column (223) to drive the scanning device (224) to rotate from one end of the item to be monitored to the other end.
