Description

Technical Field

[0001] The utility model relates to the technical field of bridge monitoring, in particular to a bridge monitoring device based on Beidou satellite. Background Art

[0002] The basic connotation of bridge health monitoring is to monitor and evaluate the structural condition of the bridge, send out early warning signals when the bridge is under special climate and traffic conditions or when the bridge operation condition is abnormally serious, and provide a basis and guidance for bridge maintenance and management decisions. During the use of the bridge monitoring device, data can be transmitted through the Beidou satellite navigation system.

[0003] For example, the utility model with application number CN202121389893.5 discloses a Beidou satellite-based bridge monitoring device. The utility model is provided with a sleeve, a slider, a slide rod, a displacement sensor, a fixing rod, a wireless transmission module, a Beidou satellite positioning module and a controller on the lower surface of the bridge body. When the bridge body cracks or sinks, the slide rod and the slider will move inside the sleeve, thereby moving the displacement sensor. At this time, the wireless transmission module, the Beidou satellite positioning module and the controller send a signal to the technician, thereby notifying the technician to take maintenance measures. Since the overall structure of the monitoring device is an isosceles trapezoid during actual use, when the middle part of the bridge sinks in an arc shape, it is equivalent to shortening the top length of the trapezoid, but a new isosceles trapezoid can still be formed when the lengths of the other three sides remain unchanged and the angles change, resulting in a certain detection blind spot problem in the detection structure.

[0004] Therefore, in view of this, research and improvement are conducted on the existing structure and deficiencies, and a bridge monitoring device based on Beidou satellite is provided. Utility Model Content

[0005] The purpose of the utility model is to provide a bridge monitoring device based on Beidou satellite to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a Beidou satellite-based bridge monitoring device, comprising a bottom shell and a detection component, the top of the bottom shell is rotatably connected to a top cover, the detection component is arranged at the left and right ends of the bottom shell, the detection component comprises a slider, a slide rod, a fixed plate, a slide plate one, a protective cover, a buffer spring, a pressure sensor and a slide plate two, one end of the slider is connected to the slide rod, and one end of the slide rod is rotatably connected to the fixed plate, one side of the middle part of the slide rod is rotatably connected to slide plate one, and the outer side of one end of slide plate one is sleeved with a protective cover, a buffer spring is arranged inside the protective cover, and one end of the buffer spring is connected to the pressure sensor, and one end of the pressure sensor is arranged with slide plate two.

[0007] Furthermore, the slide plate 2 is slidably connected to the protective cover, and the slide plate 2 is rotatably connected to the fixed plate.

[0008] Furthermore, a controller is arranged at the left middle end of the bottom shell, and a Beidou satellite positioning module is arranged at the right middle end of the bottom shell.

[0009] Furthermore, a wireless transmission module is arranged at the center of the top of the top cover, and the pressure sensor, Beidou satellite positioning module and the wireless transmission module are all electrically connected to the controller.

[0010] Furthermore, a positioning assembly is provided on one side of the top cover, and the positioning assembly includes a positioning hole and a positioning pin. A positioning hole is opened at the top of the front end of the bottom shell, and the interior of the positioning hole is slidably connected with a positioning pin.

[0011] Furthermore, the positioning assembly also includes a retaining ring and a positioning spring. The retaining ring is fixed to the outer side of the middle part of the positioning pin, and the positioning spring is arranged on one side of the retaining ring.

[0012] Furthermore, the positioning pin is slidably connected to the bottom shell, and the bottom shell is tightly fitted to the positioning spring.

[0013] Furthermore, the positioning assembly also includes a shift block and an anti-slip strip. The shift block is fixed to the top of the positioning pin, and the anti-slip strip is provided on one side of the shift block.

[0014] The utility model provides a bridge monitoring device based on Beidou satellite, which has the following beneficial effects:

[0015] 1. The utility model sets a detection component. When the middle part of the bridge sinks and bends, the lower end of the fixed plate will tilt outward. At this time, the bottom shell, the top cover and the slider can limit the direction of the slide bar, so that the angle between the slide bar and the fixed plate changes. The internal buffer spring and the pressure sensor can be squeezed by the slider one and the slider two. The pressure sensor will detect the pressure increase, and the Beidou satellite positioning module and the wireless transmission module can send signals to the staff through the controller, so that the bridge can be maintained in time, which is conducive to reducing the blind spots during equipment monitoring.

[0016] 2. The utility model provides a positioning component. When the equipment is inspected and maintained, the anti-slip strip can increase the friction between the hand and the shift block to avoid slipping when the shift block is moved. At the same time, when the shift block is moved, the positioning pin can be driven to separate from the positioning hole, so that the top cover can be opened to inspect and maintain the internal electronic components. After the top cover is covered during installation, the positioning spring can push the retaining ring so that the positioning pin is inserted into the positioning hole, and the top cover can be quickly closed and fixed, making it very convenient to operate.
