[0023] The implementation of the present application will be described in detail below with the help of drawings and examples, so that the realization process of how to apply technical means to solve technical problems and achieve technical effects can be fully understood and implemented.

[0024] Please refer to Figs. 1 to 3 The embodiment provides a kind of bridge intelligent monitoring device, including shell 1 and measuring rod 2, one end inside fixed mounting of shell 1 has pressure sensor 3, the end of shell 1 away from pressure sensor 3 is open setting, one end of measuring rod 2 is slidably inserted into the inside of shell 1 from the opening of shell 1;

[0025] Wherein, the inside of shell 1 is slidably provided with first pressing plate 5 and second pressing plate 6, spring 7 is arranged between first pressing plate 5 and second pressing plate 6, one side of first pressing plate 5 is pressed on pressure sensor 3, one end of measuring rod 2 is pressed on the side of second pressing plate 6 away from first pressing plate 5;

[0026] Wherein, one end of spring 7 is pressed on the side of first pressing plate 5 away from pressure sensor 3, the other end of spring 7 is pressed on the side of second pressing plate 6 away from measuring rod 2.

[0027] In the embodiment, the inside of shell 1 is fixedly connected with guide rod 8, the side surface of first pressing plate 5 and the side surface of second pressing plate 6 are all fixedly connected with sliding block 9, and sliding block 9 is slidably sleeved on guide rod 8. In the process of sliding of first pressing plate 5 and second pressing plate 6, sliding block 9 slides along guide rod 8, plays a guiding role, guarantees the sliding direction of first pressing plate 5 and second pressing plate 6 is accurate, avoids first pressing plate 5 and second pressing plate 6 from deviating or shaking in the process of sliding, and ensures that pressure can be accurately transmitted to pressure sensor 3.

[0028] Meanwhile, the spring 7 is sleeved on the guide rod 8, and the guide rod 8 plays a restraining role on the spring 7, so that the spring is prevented from being twisted and deformed during compression and stretching, normal work of the spring is ensured, and the measurement accuracy and stability of the device are improved.

[0029] In the embodiment, in order to facilitate fixing the shell 1 on the bridge, the opposite two side surfaces of the shell 1 are both formed with a turn-up 101, and a first mounting hole 102 is formed in the turn-up 101.

[0030] In the embodiment, the measuring rod 2 is fixedly connected with a mounting seat 201 at an end away from the shell 1, and a second mounting hole 202 is formed in the mounting seat 201, so that the measuring rod 2 can be fixed on the bridge, and field installation is facilitated.

[0031] In the embodiment, the shell 1 is fixedly installed with a measuring box 4 at one side, and a processing chip is fixedly installed in the measuring box 4. The pressure sensor 3 is electrically connected with a signal input end of the processing chip. The processing chip is signal-connected with a data collector outside through a wireless communication module. The wireless communication module can adopt a communication protocol such as Bluetooth, Wi-Fi, ZigBee, etc. The processed data is sent to the data collector outside through the wireless communication module. The monitoring personnel can remotely acquire real-time gap change data of the bridge through the data collector, so as to realize real-time monitoring of the bridge structure state. The data collector can further upload the received data to a cloud server, so as to perform more in-depth analysis and processing, such as generating a historical data curve, performing early warning analysis, etc. In the embodiment, the types of the pressure sensor 3 and the processing chip are not limited, as long as the design requirements are met. For example, the processing chip can adopt a DSP single-chip microcomputer, and the pressure sensor 3 can adopt an SPT400 pressure sensor.

[0032] In use, the shell 1 and the measuring rod 2 are fixed on both sides of the bridge gap through expansion bolts. When the bridge structure is deformed or the joint width is changed, the shell 1 and the measuring rod 2 fixed on the bridge will produce relative displacement. The expansion and contraction movement of the measuring rod 2 pushes the spring 7 to compress or stretch through the second pressing plate 6. According to Hooke's law, the deformation amount of the spring 7 is positively correlated with the bridge displacement amount. The spring force is linearly transmitted to the pressure sensor 3 through the first pressing plate 5, forming a force-displacement conversion system. When the bridge gap is enlarged, the pressure monitored by the pressure sensor 3 decreases. When the bridge gap is reduced, the pressure monitored by the pressure sensor 3 increases.
