[0002] Building tilt monitoring is an important means of ensuring the structural safety of buildings, especially for old buildings and buildings in areas with complex geological conditions, where real-time monitoring of tilt changes is of great significance.

[0003] Existing building tilt monitoring devices are typically fixed installations with sensors facing a single orientation, making it difficult to adjust them to the different wall orientations of buildings, thus limiting monitoring accuracy. Furthermore, existing devices often rely on external power supplies, leading to power supply difficulties when deployed in the field or remote areas, further restricting their application scope. In addition, the camera and data acquisition components in existing monitoring equipment are mostly exposed, lacking effective storage and protection mechanisms, making them susceptible to damage in harsh environments such as wind and rain, affecting the lifespan of the equipment and the reliability of the monitoring data. Moreover, the installation of existing devices often relies on embedded parts or simple bases, making it difficult to ensure the level of the monitoring platform on uneven ground, thus affecting the measurement accuracy of the sensors. Additionally, existing devices lack flexible height adjustment mechanisms for buildings of different heights, resulting in poor adaptability.

[0019] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] Example 1 Please refer to Figures 1-9As shown, a building tilt warning device for building monitoring includes a fixed frame 1. The fixed frame 1 consists of a set of vertical plates and four sets of horizontal plates. The four sets of horizontal plates are welded to the four side walls of the vertical plates. The top of the four sets of horizontal plates of the fixed frame 1 is fixedly connected to the circular plate 102 by reinforcing ribs 101. The bottom of each of the four sets of horizontal plates of the fixed frame 1 is provided with a drilling mechanism 2. The same set of first sleeves 103 are installed inside the vertical plates of the fixed frame 1 and inside the circular plate 102. The second sleeve 104, the third sleeve 105 and the fourth sleeve 106 are slidably installed inside the first sleeve 103. The top of the fourth sleeve 106 is rotatably connected to an electric rotating plate 107, and a detection mechanism 3 is also provided on the outer wall of the fourth sleeve 106. A storage mechanism 4 is provided inside the fourth sleeve 106. A lifting mechanism 5 is installed inside the first sleeve 103, the second sleeve 104, the third sleeve 105 and the fourth sleeve 106.

[0021] Example 2 Please refer to Figure 1 As shown, the drilling mechanism 2 includes a fixed base 201 welded to the bottom of the four sets of horizontal plates of the fixed frame 1. A rotating rod 203 is rotatably connected inside the fixed base 201. The rotation of the rotating rod 203 is driven by a first electric motor 202 installed on the outer wall of the fixed base 201.

[0022] Please refer to Figure 4 As shown, the drilling mechanism 2 also includes a lifting plate 207. A first stepper motor 204 is provided on the inner wall of the rotating rod 203. The output end of the first stepper motor 204 is fixedly connected to the outer end of the first lead screw 205. A first guide rod 206 is also fixedly installed inside the rotating rod 203. The lifting plate 207 is slidably connected to the outer wall of the first guide rod 206 and threadedly connected to the outer wall of the first lead screw 205. A second motor 208 is fixedly installed on the top of the lifting plate 207. The output end of the second motor 208 passes through the top wall of the lifting plate 207 and is fixedly connected to the drill rod 209.

[0023] Those skilled in the art will understand that when the device is in use, the output end of the first stepper motor 204 drives the first lead screw 205 to rotate, causing the lifting plate 207, the second motor 208 and the drill rod 209 to move downward as a whole. At the same time, the output end of the second motor 208 is driven to rotate, causing the drill rod 209 to rotate while moving downward, thus driving the drill rod 209 into the ground, thereby fixing the device on the ground. In addition, by driving the output terminals of the four sets of first motors 202 to rotate, the four sets of rotating rods 104 are rotated, and the angle of the four sets of rotating rods 104 is adjusted. Therefore, even when the ground is uneven, the circular plate 102 can be kept horizontal after installation.

[0024] Example 3 Please refer to Figure 3 and Figure 5 As shown, the detection mechanism 3 includes a fixed cylinder 301 fixedly installed on the outer wall of the fourth sleeve 106. A second lead screw 303 is rotatably connected to one side of the inside of the fixed cylinder 301. A second guide rod 304 is welded to the other side of the inside of the fixed cylinder 301. The outer end of the second lead screw 303 is fixedly connected to the output end of the second stepper motor 302. The second stepper motor 302 is set on the inner wall of the fixed cylinder 301.

[0025] Please refer to Figure 3 and Figure 5 As shown, a movable plate 305 is threadedly connected to the outer wall of the second lead screw 303. The movable plate 305 is slidably connected to the outer wall of the second guide rod 304. A movable rod 306 is fixedly installed on the outer wall of the movable plate 305. The other end of the movable rod 306 is fixedly connected to the pressure sensor 307.

[0026] Those skilled in the art will understand that by driving the output end of the second stepper motor 302 to rotate, the second lead screw 303 rotates, causing the moving plate 305 to reciprocate along the outer wall of the second guide rod 304, thereby enabling the pressure sensor 307 to move toward or away from the center of the circular plate 102.

[0027] Example 4 Please refer to Figure 8 and Figure 9 As shown, the storage mechanism 4 includes several sets of rotating shafts 401 rotatably connected inside the fourth sleeve 106. Transmission gears 402 are fixedly installed on the outer wall of the rotating shafts 401. An end face gear 403 is also rotatably connected inside the fourth sleeve 106. The end face gear 403 meshes with several sets of transmission gears 402.

[0028] Please refer to Figure 8 and Figure 9 As shown, a first connecting arm 404 is fixedly installed at the end of the rotating shaft 401, and the other end of the first connecting arm 404 is rotatably connected to the second connecting arm 405. One set of rotating shafts 401 is fixedly connected to the output end of the third motor 406, and the third motor 406 is fixedly installed on the inner wall of the fourth sleeve 106. The end of the second connecting arm 405 away from the first connecting arm 404 is rotatably connected to the outer wall of the mounting plate 407, and a camera 408 is installed on the top of the mounting plate 407.

[0029] Those skilled in the art will understand that when the camera 408 needs to be extended for use, the electric rotating plate 107 is driven to rotate outward, opening the top opening of the fourth sleeve 106. Then, the output end of the third motor 406 is driven to rotate, causing one set of rotating shafts 401 and transmission gears 402 to rotate as a whole, driving the end face gear 403 to rotate. This causes all rotating shafts 401 and transmission gears 402 to rotate synchronously, and consequently, the first connecting arm 404 and the second connecting arm 405 also rotate accordingly, causing the mounting plate 407 to move upward or downward. When the mounting plate 407 moves upward, the camera 408 is extended to the outside of the fourth sleeve 106 for use; when the mounting plate 407 moves downward, the camera 408 is retracted into the inside of the fourth sleeve 106.

[0030] Example 5 Please refer to Figure 6 and Figure 7 As shown, the lifting mechanism 5 includes a third stepper motor 501, a third lead screw 502, and a third guide rod 503. An installation groove is provided on the outer wall of the first sleeve 103. The third lead screw 502 is rotatably connected to the inside of the installation groove. The third guide rod 503 is fixedly installed inside the installation groove. The third stepper motor 501 is fixedly installed on the inner wall of the installation groove. The outer end of the third lead screw 502 is fixedly connected to the output end of the third stepper motor 501. A lifting component 505 is slidably connected to the third guide rod 503. The lifting component 505 is threadedly connected to the third lead screw 502. A scissor-type telescopic component 504 is rotatably connected inside the lifting component 505. The bottom two ends of the scissor-type telescopic component 504 are rotatably connected to the inside of the first sleeve 103, and the top two ends of the scissor-type telescopic component 504 are rotatably connected to the inside of the fourth sleeve 106.

[0031] Please refer to Figure 6 and Figure 7 As shown, the inner walls of the second sleeve 104, the third sleeve 105 and the fourth sleeve 106 are all provided with limiting grooves 507. The scissor telescopic member 504 is equipped with a limiting slide rod 506 that is adapted to the limiting groove 507. The limiting slide rod 506 is slidably connected to the inside of the limiting groove 507.

[0032] Those skilled in the art will understand that by driving the output end of the third stepper motor 501 to rotate, the third lead screw 502 rotates, causing the lifting component 505 to move up and down along the outer wall of the third guide rod 503, driving the scissor telescopic component 504 to be in an extended or retracted state. When the scissor telescopic component 504 is in an extended state, it drives the second sleeve 104, the third sleeve 105, and the fourth sleeve 106 to move upward synchronously, and when the scissor telescopic component 504 is in a retracted state, it drives the second sleeve 104, the third sleeve 105, and the fourth sleeve 106 to move downward synchronously, thereby changing the height of the pressure sensor 307 and the camera 408.

[0033] Example 6 Please refer to Figure 1 and Figure 3 As shown, a battery 111 is provided on the top of the circular plate 102, and a drive motor 108 is installed on the bottom of the circular plate 102. The output end of the drive motor 108 passes through the bottom wall of the circular plate 102 and a drive gear 109 is fixedly installed thereon. A driven gear 110 is fixedly connected to the outer wall of the first sleeve 103, and the drive gear 109 meshes with the driven gear 110.

[0034] Those skilled in the art will understand that all electrical devices in this device are powered by the storage battery 111, which can be recharged and reused. By driving the output end of the drive motor 108 to rotate, the drive gear 109 rotates, which drives the driven gear 110 and the first sleeve 103 to rotate as a whole, thus changing the orientation of the pressure sensor 307.

[0035] The working principle of this device is as follows: S1. By driving the output ends of four sets of first motors 202 to rotate, four sets of rotating rods 104 are driven to rotate, and the angle of the four sets of rotating rods 104 is adjusted. Then, the output end of the first step motor 204 is driven to drive the first lead screw 205 to rotate, so that the lifting plate 207, the second motor 208 and the drill rod 209 move downward as a whole. At the same time, the output end of the second motor 208 is driven to rotate, and the drill rod 209 rotates while moving downward, so that the drill rod 209 is driven into the ground. This realizes the fixed installation of the device on the ground. The circular plate 102 is kept in a horizontal state, and the first sleeve 103, the second sleeve 104, the third sleeve 105 and the fourth sleeve 106 are kept in a vertical state as a whole. S2. Based on the height of the building, the output end of the third stepper motor 501 is driven to rotate, causing the third lead screw 502 to rotate, which drives the lifting component 505 to move upward along the outer wall of the third guide rod 503, drives the scissor telescopic component 504 to be in an extended state, and drives the second sleeve 104, the third sleeve 105 and the fourth sleeve 106 to move upward synchronously, so that the height of the pressure sensor 307 is adapted to the height position of the top of the building. S3. Next, the output end of the drive motor 108 is rotated, causing the drive gear 109 to rotate, which in turn drives the driven gear 110 and the first sleeve 103 to rotate as a whole, so that the pressure sensor 307 faces the wall at the top of the building. S4. By driving the output end of the second stepper motor 302 to rotate, the second lead screw 303 rotates, which drives the moving plate 305 to move along the outer wall of the second guide rod 304 towards the wall near the top of the building, so that the pressure sensor 307 moves towards the wall near the top of the building and comes into contact with the wall. S5. Drive the electric rotating plate 107 to rotate outward, opening the top opening of the fourth sleeve 106. Then drive the output end of the third motor 406 to rotate, causing one set of rotating shafts 401 and transmission gears 402 to rotate as a whole, driving the end face gear 403 to rotate, so that all rotating shafts 401 and transmission gears 402 rotate synchronously. Then the first connecting arm 404 and the second connecting arm 405 also rotate, causing the mounting plate 407 to move upward or downward. When the mounting plate 407 moves upward, the camera 408 is extended to the outside of the fourth sleeve 106 for the camera 408 to use. The camera 408 captures the reading on the screen of the pressure sensor 307. S6. When the building tilts, pressure sensor 307 is squeezed to generate pressure. Camera 408 takes a picture of the pressure reading and transmits the picture to an external computer for analysis. When the pressure exceeds the warning number, an alarm is triggered to the staff. This is convenient and quick. Moreover, this technology is a conventional existing communication technology, so it will not be elaborated on here.

[0036] In summary, this invention, by setting up a drilling mechanism 2, utilizes a first motor 202 to drive the rotating rods 203 to rotate. When the ground is uneven, the angles of the four sets of rotating rods 203 can be adjusted to keep the circular plate 102 horizontal. Then, the first stepper motor 204 and the first lead screw 205 drive the drill rod 209 to rotate and penetrate the ground, achieving stable installation of the device. The third stepper motor 501 in the lifting mechanism 5 drives the scissor-type telescopic component 504 to extend or retract, causing the second sleeve 104, third sleeve 105, and fourth sleeve 106 to rise and fall synchronously, ensuring that the height of the pressure sensor 307 and camera 408 is adapted to the top of the building, thus having a wide range of applications. The second stepper motor in the detection mechanism 3... The motor 302 drives the second lead screw 303 to rotate, causing the pressure sensor 307 to move along the second guide rod 304 towards the building wall and make contact, thus achieving accurate pressure detection. The third motor 406 in the storage mechanism 4 drives the mounting plate 407 to rise and fall through the shaft 401, transmission gear 402 and end face gear 403, so that the camera 408 can extend when in use and be stored inside the fourth sleeve 106 when not in use, effectively protecting the camera 408. The drive motor 108 meshes with the driven gear 110 through the drive gear 109, which can rotate the first sleeve 103 to adjust the orientation of the pressure sensor 307. The overall structure is compact, with high monitoring accuracy, and facilitates real-time early warning.
