It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The embodiment of the utility model provides a protective device for concrete bridge piers, such as Figure 1-4 As shown, the protective device for concrete piers includes: an inner tube 2 movably mounted on the outside of the pier body 1; a shock-absorbing pad 3, which is mounted on the outer wall of the inner tube 2 and is used to reduce collision pressure; an outer tube 4, which is mounted on the outside of the shock-absorbing pad 3 and has a cotton pad layer on its outer wall; a controller 5, which is detachably mounted on the outer tube 4 and has a waterproof shell fixed on the outside of the controller 5; a mounting frame 15, which is mounted on the controller 5 through electrical wires and data cables and is set on the bridge deck; and a plurality of monitoring components, each of which is set on the inner wall of the inner tube 2 and is used to monitor the collision deformation of the equipment.

[0022] In this embodiment, the inner tube 2 serves as the basis of the entire protective device and can fit the pier body 1 to provide support for subsequently installed components. The shock-absorbing pad 3 is made of soft or elastic material and is used to reduce the collision pressure that may be generated by passing vehicles, effectively absorb and disperse the collision energy, protect the pier from direct impact, and extend the service life of the pier. The outer tube 4 serves as the outer layer of the protective device, further enhancing the protection of the pier. At the same time, the cotton pad layer provides additional cushioning and protection, reducing friction and damage between the vehicle and the protective device. The controller 5 is the main accessory for controlling the switch of electronic components in the device. The mounting bracket 15 is used in conjunction with the controller 5 to provide the electricity generated by the solar panel 13 to various electrical components.

[0023] In a further preferred embodiment of the present invention, a plurality of support blocks 6 are installed on the inner wall of the inner tube 2 , and balls 7 are embedded on the sides of the plurality of support blocks 6 close to each other, and the plurality of balls 7 are in contact with the outer wall of the pier body 1 .

[0024] In this embodiment, the support block 6 serves as a fixing and supporting structure, which can ensure a stable connection between the inner tube 2 and the pier body 1, reduce the displacement caused by vibration or external force, and improve the stability and reliability of the protective device. The ball 7 adopts a spherical design and can roll on the surface of the pier body 1 to reduce friction with the pier body 1. It is convenient to adjust the height of the device to observe the cracking condition of the pier body 1.

[0025] In a further preferred embodiment of the present invention, the monitoring assembly includes a spring 8, a mounting plate 9 and a trigger button 10, the spring 8 is mounted on the inner wall of the inner tube 2, the mounting plate 9 is fixed on the spring 8, the trigger button 10 is mounted on the mounting plate 9 and can contact the pier body 1, and a plurality of the trigger buttons 10 are each provided with a retractable protective shell.

[0026] In this embodiment, the spring 8 acts as an elastic element, which can absorb and disperse the impact force generated by the collision, and protect the monitoring component from direct damage. Through the buffering effect of the spring 8, the monitoring component can maintain a certain stability and reliability when it is hit, and avoid damage or failure due to external force. The mounting plate 9 is used to fix the trigger button 10 and other related components to ensure that the monitoring component can be correctly installed and work. The trigger button 10 is the core component of the monitoring component. When it is hit or under pressure, it can trigger an alarm signal to remind maintenance personnel to check and deal with it in time. The retractable protective shell not only improves the durability and reliability of the trigger button 10, but also reduces false alarms caused by accidental touch or external factors without affecting its normal operation.

[0027] In a further preferred embodiment of the present invention, a solar panel 13 is installed on the top of the mounting frame 15, a battery is provided at the bottom of the solar panel 13, the battery jacket is provided with a shell, an alarm 14 is installed on the shell, and a signal transmission module is provided in the alarm 14.

[0028] In this embodiment, the solar panel 13 serves as a green energy collection device that can convert sunlight into electrical energy to provide power support for the entire protective device. Through the use of the solar panel 13, the dependence on traditional power sources is reduced, and energy consumption and environmental pollution are reduced. At the same time, the solar panel 13 can charge the battery to ensure that under sufficient sunlight, the battery can continue to provide power for the alarm 14 and other electronic devices. The alarm 14 serves as a warning device and can send an alarm signal when the monitoring component detects an abnormality or the trigger button 10 is triggered, reminding maintenance personnel to check and handle it in time.

The two first protective plates can be respectively pasted on both sides of the pier body 1 without the need to put the entire inner tube 2 on the pier body 1. This not only reduces the difficulty of installation, but also improves the flexibility of installation. The glue bonding method ensures a close connection between the first protective plate and the pier body 1, and improves the stability of the protective device. The split design of the outer tube 4 is similar to that of the inner tube 2, which also brings convenience to installation and disassembly. The two second protective plates can correspond to the outside of the inner tube 2 respectively to form a complete protective layer.

[0033] In a further preferred embodiment of the present invention, both second protective plates are threaded with fixing bolts, both fixing bolts are movably sleeved with the same connecting plate 17, and the tops of both second protective plates are equipped with hanging rings 12 that can be connected to the crane hook.

[0034] In this embodiment, the connection between the two second protective plates can be further strengthened by using the fixing bolts and the connecting plate 17 to ensure the overall stability and safety of the protective device. This connection method is not only simple and reliable, but also easy to disassemble and repair. The design of the hanging ring 12 allows the protective device to be hoisted by a crane during installation and disassembly, greatly improving the efficiency and convenience of installation. At the same time, lifting this device can expose the obscured part of the pier body 1, making it easier to observe the cracking situation.

[0035] In summary, compared with related technologies, this device can protect the pier body 1 by setting the inner tube 2, shock-absorbing pad 3 and outer tube 4. By setting the monitoring component, it can monitor whether the device is deformed by a large collision, which is convenient for relevant personnel to take timely measures.
