Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-7In this embodiment of the present invention, a multi-point monitoring device for bridge settlement includes a base 100, three hollow columns 200, three extension rods 300, three adjusting rods 400, and three monitoring mechanisms 500. The bottom ends of the three hollow columns 200 are fixedly connected to the top surface of the base 100 at equal angles. Each of the two opposite inner sidewalls of the hollow column 200 has a sliding groove 210, and the other two sidewalls of the hollow column 200 near the top have square holes 220. Fixing components 230 are installed at the positions of the square holes 220. The three extension rods 300 are slidably inserted into the interior of the three hollow columns 200. Each of the two bottom sides of the extension rod 300 has a slider 310 fixedly connected, and the two sliders 310 are slidably connected to their corresponding two sliding grooves 210. The three adjusting rods 400 are respectively installed at the top ends of the three extension rods 300. Each adjusting rod 400 includes a connecting plate 430, and the three monitoring mechanisms 500 are respectively installed on the three connecting plates 430. The measuring mechanism 500 includes an outer cylinder 510, with alarm buttons 511 fixedly connected to both inner walls of the outer cylinder 510. An inner cylinder 520 is fixedly connected inside the outer cylinder 510. A slotted groove 521 is formed through both side walls of the inner cylinder 520, with the position of the slot corresponding to the position of the alarm button 511. A contact head 530 is located above the inner cylinder 520, and a connecting rod 531 is fixedly connected to the bottom surface of the contact head 530. The rod 531 is slidably inserted into the top surface of the inner cylinder 520. The bottom end of the connecting rod 531 is fixedly connected to the bottom block 532. The outer wall of the bottom block 532 is in contact with the inner wall of the inner cylinder 520. The two side walls of the bottom block 532 corresponding to the strip groove 521 are fixedly connected to the protrusions 533. The bottom surfaces of the two protrusions 533 are fixedly connected to the protruding posts 534. The bottom surface of the bottom block 532 is provided with a spring 535. The bottom end of the spring 535 is connected to the inner bottom surface of the inner cylinder 520.

[0032] Specifically, during installation, the base 100 is fixed to a stable surface near the bridge to ensure overall stability of the device. The length of the combination of the hollow column 200 and the extension rod 300 is adjusted by stretching the extension rod 300, ensuring that the contact head 530 at the top of the monitoring mechanism 500 mounted on the connecting plate 430 is in contact with the bridge surface. At this time, the spring 535 inside the inner cylinder 520 is in a naturally extended state, and the protruding column 534 does not touch the alarm button 511. Under normal conditions, the contact head 530 is tightly in contact with the bridge surface, and the spring 535 remains naturally extended. When the bridge settles, the bridge surface moves downward, pressing the contact head 530. The contact head 530 drives the connecting rod 531 downward, compressing the spring 535. When the settlement reaches a certain level, the downward movement of the bottom block 532 causes the protruding column 534 to press the alarm button 511, triggering the alarm button 511. The alarm module inside the device is activated, sending alarm information to relevant personnel, notifying them that the bridge may be experiencing settlement and that timely measures should be taken.

[0033] like Figure 3 and Figure 5 As shown, in this embodiment, the fixing component 230 includes two fixing frames 231 fixedly connected to the outer wall of the hollow column 200. A round rod 232 is rotatably connected between the two fixing frames 231. A knob 233 is fixedly connected to one end of the round rod 232. Two threaded grooves are symmetrically opened on the outer wall of the round rod 232. The two threads on the outer wall of the round rod 232 have opposite directions of rotation. Two movable plates 234 are screwed onto the outer wall of the round rod 232. Square rods 235 are fixedly connected to the inner side walls of the two movable plates 234. The two square rods 235 are respectively inserted into two square holes 220. The ends of the two square rods 235 located inside the square holes 220 are fixedly connected to toothed blocks 236. A rack 320 is fixedly connected to the side walls of the extension rod 300 corresponding to the two toothed blocks 236. The rack 320 meshes with the toothed blocks 236.

[0034] In this embodiment, during installation, manually rotating knob 233 drives the round rod 232 to rotate, which moves the two moving plates 234 away from each other, so that the toothed block 236 no longer meshes with the rack 320. At this time, the extension rod 300 can move up and down freely. After the length adjustment is completed, rotate knob 233 in the opposite direction to move the two moving plates 234 closer to each other, so that the two toothed blocks 236 mesh with the two racks 320 respectively, locking the length of the hollow column 200 and the extension rod 300.

[0035] like Figures 3-4 As shown, in this embodiment, a connecting post 330 is fixedly connected to the top end of the extension rod 300. The adjusting rod 400 includes an outer sleeve 410, the end of which is rotatably connected to the connecting post 330. An inner rod 420 is slidably connected inside the outer sleeve 410. The other end of the inner rod 420 is fixedly connected to the side wall of the connecting plate 430. A bolt 440 is screwed onto the top surface of the outer sleeve 410. A positioning plate 340 is fixedly connected to the top surface of the extension rod 300. A plurality of threaded holes 341 are equally spaced on the top surface of the positioning plate 340. The positions of the threaded holes 341 correspond to the positions of the bolts 440.

[0036] In practice, the monitoring mechanism 500 is installed on the connecting plate 430. The bolt 440 is unscrewed upwards to release the fixed connection between the outer sleeve 410 and the positioning plate 340. At this time, the adjusting rod 400 can be rotated around the connecting column 330 to change the monitoring position. After the adjustment is completed, the bolt 440 is screwed downwards to engage with the threaded hole 341 at the corresponding position on the positioning plate 340, thereby fixing the position of the monitoring mechanism 500.

[0037] like Figure 4As shown, in this embodiment, a threaded rod 540 is fixedly connected to the bottom surface of the outer cylinder 510, and the threaded rod 540 is screwed into the connecting plate 430. A knob 541 is fixedly connected to the bottom end of the threaded rod 540.

[0038] In practice, when the ground or the surface of the bridge is uneven, the position of the outer cylinder 510 can be adjusted up and down by rotating knob 2 541, so as to ensure that when the contact head 530 is in contact with the bridge surface, the spring 535 is in a naturally extended state without pressure.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
