Description

Technical Field

[0001] The utility model relates to the technical field of bridge column vibration, in particular to a bridge column vibration monitoring device. Background Art

[0002] Bridge vibration is a complex phenomenon involving multiple factors, including structural design, material properties, load distribution, environmental conditions, etc.

[0003] Bridge vibration monitoring is an important means of ensuring bridge safety and stability. By monitoring bridge vibration in real time, potential safety hazards and structural damage can be promptly identified. For example, prior art Chinese Patent Publication No. "CN216869537U" provides a bridge condition monitoring device for bridge engineering, relating to the field of bridge condition monitoring technology. The device comprises a bridge column, a buffer shock absorber, a bridge vibrator, a bridge inclinometer, and a data collector. The buffer shock absorbers are provided on both sides of the top outer surface of the bridge column, and the bridge vibrator is detachably mounted on the top outer surface of the bridge column. The present invention secures the top plate to the bottom of the bridge deck, using a through-pillar that passes through a U-shaped hollow frame and then locks it with an annular lock. The U-shaped hollow frame at the bottom of the top plate vibrates downward, driving a vibration detector and collector on the surface of the annular lock to vibrate and collect vibration data. This device has the advantage of detecting bridge vibration, resolving the problem of vibration resonating with the bridge deck itself, which can cause cracks in the bridge deck if repeated. This effectively detects bridge vibration.

[0004] At present, after a bridge is put into use, its safety needs to be monitored in real time. The main problem affecting the safety of the bridge is vibration, especially the strength of the horizontal vibration amplitude, which is more harmful than the vertical vibration. These vibrations come from the passage of vehicles and the geological conditions of the ground. Therefore, it is necessary to design a system to monitor the beams and columns when they produce horizontal vibrations. Utility Model Content

[0005] The purpose of the utility model is to solve the above-mentioned shortcomings in the prior art and to propose a bridge column vibration monitoring device.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A bridge column vibration monitoring device is designed, comprising a mounting plate, a protective cover provided on one side of the mounting plate, a box body provided inside the protective cover, the box body having a rectangular structure, pressure sensors provided on both sides of the box body, and a spring provided inside the box body, the two ends of the spring being fixedly assembled to the inner wall of the box body and the surface of the pressure sensor respectively;

[0008] Tracks are fixed at both ends of the inner wall of the box body, and a steel ball is arranged to roll between the two tracks, and the steel ball is located between the two pressure sensors;

[0009] A through hole is provided on one side of the box body, and the through hole is a strip-shaped hole structure. The connection terminal of the pressure sensor is fixedly connected with a data line, and the data line passes through the through hole.

[0010] It should be further explained that a processor is fixed on one side of the mounting plate, the processor is arranged inside the protective cover, and the connection terminal of the processor is inserted and docked with the data cable.

[0011] It should be further explained that a wireless signal transceiver is fixed to one side of the mounting plate, the wireless signal transceiver is arranged inside the protective cover, and the processor is electrically connected to the wireless signal transceiver via a wire.

[0012] It should be further explained that positioning plates are fixed to both the upper and lower ends of the mounting plate, positioning holes are provided inside the positioning plates, and the inner walls of the positioning holes are smooth or threaded surfaces.

[0013] It should be further explained that alignment blocks are fixed to both ends of the mounting plate, and alignment seats are fixed to both sides of the protective cover, and the alignment blocks and the alignment seats are slidably inserted and docked.

[0014] It should be further explained that a groove is provided inside the alignment block, a latch is slidably sleeved inside the groove, a second spring is provided inside the groove, and the two ends of the second spring are fixedly assembled with the inner wall of the groove and the surface of the latch respectively.

[0015] It should be further explained that a pin hole is provided inside the alignment seat, and the surface of the latch pin is slidably penetrated by the inside of the pin hole.

[0016] The design scheme proposed by the utility model has the following beneficial effects during application:

[0017] 1. The box body is set up so that the steel ball can slide inside the box body. After the box body is fixed to the mounting plate, it can be fixed to the bridge column perpendicular to the ground, so that the box body can be set horizontally. The mounting plate and the column can be fixed by using the positioning plates distributed along the upper and lower ends of the mounting plate in conjunction with their positioning holes and screws. When there is a large horizontal vibration, the steel ball will swing left and right on the track inside the box body and collide with the pressure sensors on both sides, causing the signal fluctuation of the pressure sensor to become larger. The spring can play a buffering effect, and the signal can be analyzed and compared by the processor. Then, the signal is remotely transmitted through the wireless signal transceiver, so that technicians can monitor the safety of the bridge regularly.

[0018] 2. In order to facilitate the protection of the monitoring components, the protective cover and the mounting plate can be used to protect the components from dust and rain. When the internal components need to be repaired, the bayonet is pressed so that the bayonet can compress the spring 2 and allow the bayonet to enter the groove. Thus, the bayonet and the pin hole can be disengaged, and then the alignment block and the alignment seat can be separated. Finally, the assembly and disassembly of the protective cover and the mounting plate can be facilitated. BRIEF DESCRIPTION OF THE DRAWINGS

The wireless signal transceiver 21 is arranged inside the protective cover 11. The processor 2 is electrically connected to the wireless signal transceiver 21 through a wire. The information processed by the processor 2 can be remotely transmitted through the wireless signal transceiver 21 and sent to the technician's receiving terminal.

[0030] It should be further explained that positioning plates 3 are fixed at both upper and lower ends of the mounting plate 1, and positioning holes 31 are provided inside the positioning plates 3. The inner wall of the positioning holes 31 is a smooth surface or a threaded surface. The positioning plates 3 cooperate with the positioning holes 31 to install and fix the overall structure to the bridge column.

[0031] It should be further explained that alignment blocks 4 are fixed at both ends of the mounting plate 1, and alignment seats 41 are fixed on both sides of the protective cover 11. The alignment blocks 4 and the alignment seats 41 are slidably inserted and docked. By installing the alignment blocks 4 and the alignment seats 41, the mounting plate 1 and the protective cover 11 can be quickly positioned and docked.
