Description

[0002] The bridge temperature monitoring system is an important technology in the field of bridge structure health monitoring. In large-scale bridge projects, temperature changes are one of the important factors affecting the stress and deformation of the bridge structure. When the bridge is affected by temperature changes, it will cause changes in the internal stress and deformation of the bridge, which in turn affects the safety and stability of the bridge. Therefore, by establishing a bridge temperature monitoring system, the temperature changes of the bridge can be monitored in real time and accurately, providing protection for the safe operation of the bridge.

The accompanying drawings are used to depict the embodiments of the present invention for illustrative purposes only. Those skilled in the art will easily recognize from the following description that alternative embodiments of the structures and methods shown in the present invention can be adopted without departing from the principles of the present invention.

[0053] A bridge temperature monitoring device according to an embodiment of the present invention is provided on a bridge body 1 and includes:

[0054] A movable shell 2 is provided on the top of the bridge body. The movable shell 2 is provided with slide grooves 6 on both sides in the first direction. The movable shell 2 is provided with clamping plates 4 on the bottom of both sides in the second direction. A temperature sensor 5 is installed inside the clamping plates 4.

[0055] The moving assembly includes a moving plate 7 that is slidably connected to the inside of the slide 6. Both ends of the moving plate 7 pass through the moving shell 2, and both ends of the moving plate 7 are fixedly connected to a dual-axis motor 8. The output end of each dual-axis motor 8 is fixedly connected to a transmission rod 9. Both ends of the transmission rod 9 are fixed with moving wheels 10. The dual-axis motor 8 controls the moving wheels 10 to rotate or stop rotating on the bridge body 1 to move the bridge temperature monitoring device to the target monitoring position.

[0056] The driving assembly is arranged inside the movable shell 2 and connected to the clamping plate 4. The driving assembly is used to control the clamping plate 4 to clamp or move away from the bridge body 1 to monitor the temperature of the bridge body 1 when the temperature sensor 5 contacts the bridge body 1.

[0057] The two sides of the movable shell 2 mentioned in the present invention in the first direction refer to the two sides parallel to the length direction of the bridge body 1 when the bridge temperature monitoring device is installed on the bridge body 1, and the two sides of the movable shell 2 in the second direction refer to the two sides perpendicular to the length direction of the bridge body 1 when the monitoring device is installed on the bridge body 1.

[0058] like Figure 1 、 Figure 2 、 Figure 4As shown, when the temperature of the bridge body 1 needs to be tested, the staff can manually take the movable shell 2 and move the four sets of movable wheels 10 to the top of the side of the bridge body 1, and then start the dual-axis motor 8 through the external controller. The dual-axis motor 8 drives the transmission rod 9 and the movable wheel 10 to rotate in turn. The friction force between the movable wheel 10 and the top of the bridge body 1 drives the bridge temperature monitoring device to move, thereby realizing the function of automatically adjusting the temperature monitoring position.

[0059] After the bridge temperature monitoring device moves to the target monitoring position, the drive assembly is activated by an external controller. The drive assembly controls the clamping plate 4 to clamp the bridge body 1. The clamping plate 4 moves while driving the temperature sensor 5 to contact the bridge body 1 to monitor the temperature of the bridge body 1. After the initial detection is completed, the drive assembly controls the clamping plate 4 to drive the temperature sensor 5 away from the bridge body 1. The dual-axis motor 8 is then activated again to drive the moving wheel 10 to rotate and adjust the monitoring position to achieve adjustable monitoring of different positions. Among them, the target monitoring position is a plurality of temperature monitoring points confirmed by the staff based on the condition of the bridge to be monitored.

[0060] Among them, the working principle of the temperature sensor 5 in the present application is: the temperature sensor 5 is mainly composed of a thermistor, which is a semiconductor device whose resistance changes with temperature. The resistance value of the thermistor decreases with increasing temperature (negative temperature coefficient), or increases with increasing temperature (positive temperature coefficient). When the thermistor is exposed to the surface of the bridge body 1, as the temperature of the bridge body 1 changes, the resistance value of the thermistor changes accordingly. The change value can be connected to the circuit to convert it into a temperature measurement value. Through pre-calibration and calibration, the change in the resistance value of the thermistor can be accurately converted into a digital or analog signal output of the temperature to achieve the function of monitoring the temperature of the bridge body 1.

[0061] The bridge temperature monitoring device of the present invention can adjust the position of the monitored temperature in real time, and does not require staff to manually install the monitoring device on the top of the bridge body, thereby improving detection efficiency and facilitating the extraction of temperature data at different positions of the bridge body.

[0062] An optional implementation method, such as Figure 3 As shown, the bridge temperature monitoring device also includes: an infrared temperature sensing probe 3, which is fixed to the side of the movable shell 2 facing the bridge deck and connected to the driving component to adjust the position of the infrared temperature sensing probe 3 through the driving component.

[0063] When working, the infrared temperature sensing probe 3 shines towards the road surface of the bridge body 1. The infrared temperature sensing probe 3 contains a sensor element that can sense infrared radiation. When the infrared temperature sensing probe 3 is aimed at the bridge surface, the infrared temperature sensing probe 3 will receive the infrared radiation emitted by the road surface. The sensor inside the infrared temperature sensing probe 3 will convert the received infrared radiation into electrical signals. Through internal circuit processing, these signals are converted into corresponding temperature values. The infrared temperature sensing probe 3 obtains the surface temperature of the object by measuring the infrared radiation emitted by it, and can obtain accurate bridge surface temperature data quickly and non-contact.

[0064] An optional implementation method, such as Figure 6 、 Figure 7 As shown, the driving component includes:

[0065] The driving motor 14 is fixed inside the movable shell 2 and is located on the side away from the bridge deck;

[0066] The rotating rod 15 is fixed to the output end of the driving motor 14;

[0067] Two first gears 16 are sleeved on the rotating rod 15 , and the driving assembly controls the clamping plate 4 to clamp or move away from the bridge body 1 through the two first gears 16 .

[0068] Preferably, the driving assembly is connected to the clamping plate 4 via the fixing assembly, and the fixing assembly includes two adjustment units respectively arranged to cooperate with the two clamping plates 4, and the adjustment units include:

[0069] Threaded rod 11;

[0070] The movable sleeve 12 is threadedly connected to one end of the threaded rod 11;

[0071] An adjusting plate 13, one end of which is fixedly connected to the bottom of the movable sleeve 12, and the other end of which passes through the movable shell 2 and is fixedly connected to the clamping plate 4;

[0072] The second gear 23 is sleeved on the other end of the threaded rod 11 and meshes with the bottom of the first gear 16;

[0073] The threads on the surfaces of the two threaded rods 11 are opposite to each other.

[0074] Preferably, the bridge temperature monitoring device further includes:

[0075] The top of the rotating plate 24 is connected to the end of the rotating rod 15, and the bottom of the rotating plate 24 is fixedly connected to the infrared temperature sensing probe 3;

[0076] The protective shell 25 is sleeved on the surface of the infrared temperature sensing probe 3 and is fixedly connected to the movable shell 2 .

[0077] The protective shell 25 is sleeved on the surface of the infrared temperature sensing probe 3 to prevent dust and provide protection, thereby improving the measurement accuracy and service life of the infrared temperature sensing probe.

[0078] It can be understood that there are two threaded rods, and the surfaces of the two groups of threaded rods 11 are movably connected to the inner wall of the movable shell 2 through bearings. The opposite sides of the two threaded rods 11 are movably connected to the bearing seats, and the bottom of the bearing seats is fixedly connected to the movable shell 2. The threads on the surfaces of the two groups of threaded rods 11 are opposite, and when the threaded rods 11 rotate, the two groups of clamping plates 4 can be driven to move relative to and oppositely (that is, drive the two groups of clamping plates 4 to clamp or move away from the bridge body 1).

[0079] Specifically, the gear ratio of the first gear 16 to the second gear 23 is 4 to 1. When the first gear 16 rotates one circle, the second gear 23 can be driven to rotate four times. The second gear 23 drives the threaded rod 11 to rotate, thereby adjusting the position of the movable sleeve 12.

[0080] After the bridge temperature monitoring device moves to the target monitoring position, the drive motor 14 is started through the external controller, and the drive motor 14 cooperates with the rotating rod 15 to drive the rotating plate 24 to rotate 90 degrees counterclockwise, and the rotating plate 24 drives the infrared sensing probe to separate from the protective shell 25 and shine it toward the bridge deck to monitor and obtain the first temperature; while the rotating rod 15 rotates, it drives the two sets of first gears 16 to rotate, and the first gear 16 cooperates with the second gear 23 to drive the threaded rod 11 to rotate, and the threaded rod 11 cooperates with the movable sleeve 12 to drive the adjustment plate 13 to move, and the adjustment plate 13 drives the clamping plate 4 to contact and clamp the bridge body 1 to fix the monitoring device on the bridge body 1, so as to facilitate long-term temperature monitoring of the bridge body 1 and increase the stability during detection. While the clamping plate 4 moves, it drives the temperature sensor 5 to contact the bridge body 1 to monitor and obtain the second temperature. The accuracy of temperature monitoring is increased by statistical comparison of multiple temperature data.

[0081] The first temperature and the second temperature measured by the bridge temperature monitoring device of the present invention can simultaneously monitor the temperature of the bridge body and the temperature of the bridge deck in the bridge, thereby improving the accuracy of bridge temperature extraction.

[0082] The side of the movable shell 2 facing the bridge deck mentioned in the present invention refers to the side facing the inner side of the bridge body perpendicular to the length direction of the bridge body 1, and the side of the movable shell 2 away from the bridge deck refers to the side facing the outer side of the bridge body perpendicular to the length direction of the bridge body 1.

[0083] An optional implementation method, such as Figure 2 、 Figure 4 as well as Figure 8 As shown,

[0084] The mobile component includes:

[0085] A slide bar 18 passes through the movable plate 7 and is slidably connected to the movable plate 7. The top and bottom of the slide bar 18 are fixedly connected to the inner walls of the top and bottom of the slide groove 6. A tension spring 19 is sleeved on the surface of the slide bar 18. The top and bottom ends of the tension spring 19 are respectively fixedly connected to the movable plate 7 and the inner wall of the top of the slide groove 6. A cam 17 is fixed to the surface of the rotating rod 15. The cam 17 is located between the two first gears 16, and the cooperation between the cam 17 and the tension spring 19 is used to control the contact or separation of the movable wheel 10 from the bridge body 1.

[0086] Specifically, after the bridge temperature monitoring device moves to the target monitoring position, the drive motor 14 is started through the external controller, and the rotating rod 15 rotates while driving the cam 17 to rotate 90° counterclockwise. The rotation of the cam 17 cancels the push on the movable plate 7. At this time, the tension spring 19 will drive the movable plate 7 to move upward, and the movable plate 7 cooperates with the dual-axis motor 8 to drive the movable wheel 10 away from the bridge body 1. While monitoring the temperature, the possibility of sudden movement of the bridge temperature monitoring device is reduced, and the bridge body is clamped by the clamping plate 4 to increase the stability of the bridge temperature monitoring device when monitoring the temperature, which is convenient for long-term temperature monitoring of a certain position.

[0087] Preferably, the two clamping plates 4 are fixedly connected to opposite sides thereof with counterweight blocks 26 , which can increase the weight of the bottom of the movable shell 2 and improve the stability during movement.

[0088] In an optional embodiment, limiting wheels 20 are respectively sleeved on the surfaces of both ends of the transmission rod 9, a fixing ring 21 is fixed to the side of the limiting wheel 20 away from the dual-axis motor 8, and a fixing pin 22 is threadedly connected to the top of the fixing ring 21.

[0089] It can be understood that the fixing ring 21 and the limiting wheel 20 are both mounted on the surface of the transmission rod 9, and the fixing pin 22 is threadedly connected to the top of the fixing ring 21. By rotating the fixing pin 22, the fixing ring 21 can be fixed to the surface of the transmission rod 9. When the thickness of the side of the bridge is large, the position of the limiting wheel 20 can be adjusted by rotating the fixing pin 22 to increase the fit with the side of the bridge and improve stability during movement.

[0090] In an optional embodiment, the bridge temperature monitoring device further includes:

[0091] A bracket 28 is fixed to the top of the mobile shell 2;

[0092] A wireless transmitter 29 is provided on the top of the mobile shell 2 and is fixedly connected to the bracket 28;

[0093] The solar cell panel 30 is disposed adjacent to the wireless transmitter 29 and is fixedly connected to the mobile shell 2 .

[0094] The wireless transmitter 29 adopts a GPS wireless transmission module, which can upload temperature data to an external control terminal to achieve real-time detection. The solar panel 30 can convert light energy into electrical energy to facilitate powering the equipment inside the mobile shell 2.

[0095] A bridge temperature detection method according to an embodiment of the present invention includes:

[0096] S1: Place the bridge temperature monitoring device on the bridge body 1, start the drive motor 14, and sequentially drive the rotating rod 15 and the cam 17 to rotate 90 degrees clockwise. The cam 17 rotates and pushes the movable plate 7 to move the movable plate 7 downward, so that the four sets of movable wheels 10 are placed on the top of the bridge body 1. Start the dual-axis motor 8, and sequentially drive the transmission rod 9 and the movable wheels 10 to rotate, so that the bridge temperature monitoring device is moved to the target monitoring position;

[0097] S2: After the bridge temperature monitoring device reaches the target monitoring position, the drive motor 14 is started, which in turn drives the rotating rod 15 and the rotating plate 24 to rotate 90 degrees counterclockwise. The rotating plate 24 drives the infrared temperature sensing probe 3 to separate from the protective shell 25 and shine it toward the road surface of the bridge body 1 to detect the first temperature of the bridge body 1;

[0098] S3: When the rotating rod 15 rotates, it drives the cam 17 to rotate 90° counterclockwise. The rotation of the cam 17 cancels the push on the movable plate 7. The tension spring 19 drives the movable plate 7 to move upward, so that the movable wheel 10 moves away from the bridge body 1. When the rotating rod 15 rotates, it drives the two sets of first gears 16 to rotate. The first gear 16 cooperates with the second gear 23 to drive the threaded rod 11 to rotate. The threaded rod 11 cooperates with the movable sleeve 12 to drive the adjustment plate 13 to move. The adjustment plate 13 drives the clamping plate 4 to contact the bridge body 1 and clamp the bridge body 1 to fix the bridge temperature monitoring device on the bridge body 1;

[0099] S4 : The clamping plate 4 moves and drives the temperature sensor 5 to contact the bridge body 1 to detect the second temperature of the bridge body 1 .
