Description

Technical Field

[0001] This utility model relates to the technical field of protective structures for bridge piers, and in particular to a safety monitoring device for bridge piers. Background Technology

[0002] As the core load-bearing components of bridges on highways and bridge-related sections, the structural stability of bridge piers directly determines the bridge's load-bearing capacity, disaster resistance under extreme conditions, and traffic safety. Given my country's complex geographical environment, widespread mountainous areas, and varied geological conditions, the safety of bridge piers has always been a focus of attention for engineering and research personnel during road operation.

[0003] Even after the bridge piers are constructed, the surrounding geological environment may still be in a state of dynamic change. Therefore, continuous monitoring of the bridge piers is necessary to promptly grasp their condition and take appropriate remedial measures, thereby ensuring the safety of the piers themselves and surrounding structures. Bridge pier monitoring mainly includes observing their displacement and overall or local deformation, aiming to identify early signs of pier structural failure, and recording and analyzing key parameters such as displacement velocity and direction.

[0004] Currently, bridge pier displacement measurement mainly relies on manual observation methods. However, this method has many limitations in practical applications: observation conditions are difficult in some areas, and it is impossible to carry out work under the bridge in severe weather conditions, posing a high safety risk to workers; in addition, manual monitoring is labor-intensive and inefficient, and also suffers from insufficient monitoring accuracy and delayed data feedback, making it difficult to meet the real-time and accuracy requirements of modern bridge safety management.

[0031] It should be understood that the accompanying drawings are not necessarily drawn to scale, but rather present simplified representations of various features to illustrate the basic principles of this invention. The specific design features disclosed in this invention (including, for example, specific dimensions, orientations, positions, and shapes) will be determined in part by the specific application and environment in which they will be used.

[0032] Throughout these figures, the same reference numerals denote the same or equivalent parts of the present invention. Detailed Implementation

[0033] The present invention will now be described in detail with reference to various embodiments, examples of which are presented in the accompanying drawings and described below. Although the present invention will be described in conjunction with exemplary embodiments, it should be understood that this specification is not intended to limit the present invention to these exemplary embodiments. Rather, the present invention is intended to cover not only these exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments that may be included within the spirit of the present invention and the scope defined by the appended claims.

[0034] When a component is referred to as being "above" or "on top of" another component, the component may be in contact with the other component, or the component may be spaced apart from the other component, or there may be an intermediate component between the component and the other component.

[0035] The following is combined Figures 1 to 6 The safety monitoring device for bridge piers according to the present invention will be described.

[0036] The bridge pier safety monitoring device of this utility model can be applied to the safety monitoring of the entire bridge pier, partial pier, and water-crossing pier, and is also suitable for the health diagnosis of bridge pier structures.

[0037] like Figure 1 As shown, the bridge pier safety monitoring device of this utility model includes: a flexible composite material device 2, a linear sensor 1, and a control terminal 4.

[0038] The flexible composite material device 2 is installed on the bridge pier.

[0039] Linear sensor 1 is installed inside the flexible composite material device 2 and is able to sense the displacement and deformation information of the bridge pier.

[0040] Control terminal 4 is electrically connected to the linear sensor 1.

[0041] The linear sensor 1 can send the sensed displacement and deformation information to the control terminal 4.

[0042] This invention enables continuous, all-round monitoring of bridge piers, as well as localized monitoring. It boasts high accuracy and stability, is easy and flexible to install, and better serves the safety monitoring of bridge piers.

[0043] In an exemplary embodiment, the flexible composite material device 2 is made of array fabric composite (AFC). The flexible composite material device 2 can conform to the curved surface of the pier and adapt to certain deformations. The flexible composite material device 2 features strong energy absorption, resistance to high and low temperatures, corrosion resistance, aging resistance, and lightweight design.

[0044] like Figure 2 As shown, the flexible composite material device 2 includes a main body 21, bolts 22, and nuts 23. The main body 21 is installed to the bridge pier column by bolts 22 and nuts 23.

[0045] In an exemplary implementation, such as Figure 2 As shown, the flexible composite material device 2 also includes a steel plate 24, which is disposed between the main body 21 and the bridge pier.

[0046] The main body 21 can be modified according to the specific dimensions of the pier. During installation, the main body 21 is attached to the bridge pier using the snap-fit ​​mechanism, and the steel plate 24 is placed on the bolts 22 and secured with nuts 23 to ensure that the main body 21 fits tightly against the bridge pier.

[0047] In an exemplary implementation, such as Figure 2 As shown, the flexible composite material device 2 also includes a reflective sticker 25, which is disposed on the outer surface of the main body 21. The reflective sticker 25 is used to generate reflection under light, serving as a warning and improving safety at night or in low light environments.

[0048] The number of linear sensors 1 can be increased or decreased depending on the specific bridge pier conditions.

[0049] In an exemplary implementation, such as Figure 3 As shown, the linear sensor 1 includes several measuring units 13, a plug 12, and a cap 15.

[0050] Several measuring units 13 are distributed at a preset interval. For example, one measuring unit 13 is distributed every 100 centimeters and encapsulated inside the linear sensor 1 to adapt to the monitoring needs of special scenarios.

[0051] The plug 12 is located at the beginning of each measuring unit 13 and is used to integrate the connecting wire 11.

[0052] The cap 15 is installed at the tail end of each measuring unit 13 to provide a seal.

[0053] In an exemplary embodiment, a connecting line 11 is provided at the plug 12, and the measuring unit 13 is electrically connected to the control terminal 4 through the connecting line 11, thereby enabling the sensed displacement deformation information to be transmitted to the control terminal 4.

[0054] Furthermore, the connection line 11 is configured as two lines, one as the main line and the other as a backup line, ensuring that the system can continue to work through the backup connection line 11 even if one of the connection lines 11 fails, which greatly improves the reliability of the monitoring system.

[0055] Among them, the plug 12 is the first section of the sensor, the plug cap 15 is the last section of the sensor, and the measurement unit 13 is a measurement unit with each 100cm. It can perform three-dimensional deformation (displacement) measurement in X / Y / Z dimensions. The measurement unit 13 is triggered to collect data or timed to collect data, and performs comprehensive calculation and analysis on the monitoring data.

[0056] The linear sensor 1 further includes a housing 14, preferably made of 304 stainless steel, forming a high-strength, waterproof, and sealed tubular structure, the total length of which can be extended according to engineering needs (e.g., up to 120 meters). The housing 14 has an IP68 protection rating, effectively preventing corrosion, lightning strikes, static electricity, and impacts. Specifically, the housing 14 constitutes a wire braided sleeve.

[0057] In addition, the housing 14 has the ability to be bent at will and can be repeatedly disassembled and reused as needed for engineering purposes.

[0058] The housing 14 can be bent arbitrarily, which makes the shape of the linear sensor 1 inconsistent.

[0059] The measurement unit 13 is attached to the bridge pier through the prefabricated lines in the flexible composite material device 2. The lines are densely distributed and closely attached to the uneven slope to carry out full coverage measurement.

[0060] like Figure 4 As shown, the linear sensor 1 of this invention is configured with an S-shaped linear structure according to the shape of the bridge pier. Different types of meshes can be used for different key monitoring areas of the bridge pier, such as diamond mesh, triangular mesh, and sawtooth mesh. The mesh can be configured as a dense mesh or a loose mesh according to the deformation requirements of the bridge pier, and local deformation monitoring can also be performed. The specific configuration depends on the site conditions, making it quite flexible in practice. Compared to other bridge pier monitoring devices, the bridge pier safety monitoring device of this invention has a measuring unit 13 every 100cm inside the linear sensor 1, resulting in numerous internal measuring units 13, thus making the measurement results more reliable and accurate.

[0061] In an exemplary implementation, Figure 4The diagram shows a top view of the linear sensor arrangement of this utility model. The example diagram of this utility model shows an S-shaped linear structure. The linear sensor 1 senses the three-dimensional deformation data (i.e., displacement deformation information) of the object in real time. The three-dimensional deformation data is transmitted to the control terminal 4 in real time through the RS485 universal interface.

[0062] Figure 5 This is a schematic diagram of the main structure of the linear sensor arrangement of this utility model. The linear sensor 1 spreads outwards, and its distribution position is flexible and can be flexibly handled according to the actual bridge pier and column protection area.

[0063] In an exemplary embodiment, the measuring unit 13 can be bent arbitrarily and is distributed in large numbers, enabling it to perform three-dimensional deformation (displacement) measurement in the X / Y / Z dimensions, and to measure its deformation characteristics in a timely manner.

[0064] In an exemplary implementation, such as Figure 1 As shown, the bridge pier safety monitoring device of this utility model further includes a transmission line 3, and a connecting line 11 is electrically connected to the first end of the transmission line 3.

[0065] Control terminal 4 is a multi-functional integrated data and transmission terminal that enables data triggering, acquisition, and uploading. It can integrate image acquisition, rainfall monitoring, alarm, and other devices, effectively solving data transmission problems in remote and large-scale areas. It is suitable for temporary monitoring scenarios such as emergency response and disaster relief.

[0066] In an exemplary implementation, such as Figure 6 As shown, the control terminal 4 includes a microprocessor system 413, which is electrically connected to the second end of the transmission line 3. The measurement unit 13 can transmit the sensed displacement and deformation information of the bridge pier to the microprocessor system 413 through the connection line 11 and the transmission line 3. The microprocessor system 413 has a high-speed processor and a sensitive operating system, and has the function of collecting, processing and transmitting displacement and deformation information.

[0067] In an exemplary implementation, such as Figure 6 As shown, the control terminal 4 also includes a battery compartment 401 and a first solar panel 411.

[0068] The battery compartment 401 is equipped with a rechargeable battery (such as a lithium-ion battery pack). The rechargeable battery is electrically connected to the first solar panel 411 and the microprocessor system 413. The first solar panel 411 can charge the rechargeable battery, and the rechargeable battery can supply power to the microprocessor system 413.

[0069] In an exemplary implementation, such as Figure 6As shown, the control terminal 4 also includes a locator 412 (e.g., a GPS module or a Beidou module). The locator 412 is electrically connected to the microprocessor system 413. The locator 412 can send its own location information to the microprocessor system 413, and then upload it to the secure IoT platform. In areas with harsh geological conditions, if a fault occurs, staff can accurately locate the control terminal 4 with the uploaded information. Specifically, managers can clearly grasp the deployment location of each field device on the platform. Especially in remote areas with harsh geological conditions and sparse equipment distribution, when the system alarms or requires maintenance, staff can quickly and accurately locate and find the target device based on the uploaded location information, greatly improving operation and maintenance efficiency and safety.

[0070] In an exemplary implementation, such as Figure 6 As shown, the control terminal 4 also includes a communication module indicator light 403, a power switch 404, an RS485 universal interface 405, a button 406, a status indicator light 407, a communication antenna 408, a display 409, and a SIM card 410.

[0071] The communication module indicator light 403 is electrically connected to the microprocessor system 413 and is specifically used to indicate the operating status of the wireless communication module (such as data transmission / reception).

[0072] The power switch 404 is used to control the on / off state of the main circuit of the control terminal 4.

[0073] The RS485 universal interface 405 is used for reliable wired data communication and can be stably connected to devices such as linear sensors 1.

[0074] Button 406 provides manual input functions such as local parameter settings and function switching.

[0075] Status indicator 407 displays the current status of control terminal 4 (such as power, running, fault) intuitively through different colors or flashing patterns.

[0076] The communication antenna 408 is installed above the control terminal 4 to enhance the transmission and reception capabilities of wireless signals such as 4G / 5G, and to enable remote data transmission.

[0077] Display 409 is used for local display of system status, real-time data, or device parameters.

[0078] The SIM card 410 serves as an identification identifier and accesses the mobile communication network.

[0079] Data from linear sensor 1 (including displacement and deformation information) enters control terminal 4 via RS485 universal interface 405. After processing by microprocessor system 413, it can be viewed locally on display 409 and transmitted to the cloud (i.e., secure IoT platform) via a wireless link consisting of SIM card 410 and communication antenna 408. The system status throughout the process is overviewed by status indicator 407, while the health status of the communication link is specifically indicated by communication module indicator 403. Power switch 404 provides overall power control, and button 406 allows on-site personnel to perform necessary interactive operations.

[0080] In an exemplary implementation, such as Figure 6 As shown, the control terminal 4 also includes a transparent protective cover 402.

[0081] The microprocessor system 413, battery compartment 401, first solar panel 411, locator 412, communication module indicator light 403, status indicator light 407, communication antenna 408, display 409, and SIM card 410 are housed inside the transparent protective cover 402.

[0082] The transparent protective cover 402 provides sunlight to the first solar panel 411, allowing the first solar panel 411 to store electricity. In cloudy or rainy weather, it can be charged by a rechargeable battery inside the battery compartment 401.

[0083] In an exemplary implementation, such as Figure 1 As shown, the bridge pier safety monitoring device further includes a height-adjustable support column 7 and a second solar panel 9. The second solar panel 9 is located outside the control terminal 4 and is mounted to the support column 7. Operators can adjust the height of the second solar panel 9 via the support column 7. The second solar panel 9 is electrically connected to a rechargeable battery inside the battery compartment 401 to charge the rechargeable battery. The area of ​​the second solar panel 9 is not limited by the transparent protective cover 402 and can be appropriately enlarged to increase the charging capacity.

[0084] The flexible composite material device 2 is used to protect the bridge piers and to deploy the linear sensor 1. Generally, the flexible composite material device 2 is used to combine monitoring and protection to avoid the occurrence of dangers and to detect the displacement data of the bridge piers in a timely manner. In specific situations, only the linear sensor 1 can be used for the safety monitoring of the bridge piers.

[0085] In an exemplary implementation, such as Figure 1 As shown, the bridge pier safety monitoring device further includes a tripod 5, with a circular connection port 6 at the top of the tripod 5, a support column 7 vertically installed in the circular connection port 6, and a control terminal 4 installed on the support column 7.

[0086] In an exemplary implementation, such as Figure 1 As shown, the bridge pier safety monitoring device further includes a horizontal column 8, on which a horn 101 and a camera 102 are mounted. Both the horn 101 and the camera 102 are electrically connected to the microprocessor system 413. The camera 102 is used to acquire images, and the horn 101 is used for alarm.

[0087] The viewing angle of camera 102 is adjusted to cover the target bridge pier and its surrounding area. Camera 102 is used to collect video or image information of the surrounding environment of the bridge pier in real time.

[0088] When the linear sensor 1 detects abnormal deformation or displacement of the pier, the microprocessor system 413 can automatically call the camera 102 to capture real-time images, allowing managers to intuitively review the on-site situation, such as distinguishing between structural damage and external events like vehicle collisions.

[0089] In addition, the video data recorded by camera 102 can be used for cause analysis and tracing after accidents or abnormal events.

[0090] The sound field of the speaker 101 can effectively cover the target area, and the speaker 101 is used to emit sound warnings on site.

[0091] When the monitoring system determines that the pier is in a dangerous state (such as excessive displacement), the microprocessor system 413 can drive the horn 101 to emit continuous alarm sounds or voice prompts to warn passing vehicles and pedestrians to detour and avoid danger, thereby achieving active safety protection.

[0092] Managers can use the remote platform and the microprocessor system 413 to control the loudspeaker 101 to make remote voice announcements, drive away suspicious persons, or conduct command and dispatch.
