[0002] Bridge settlement monitoring refers to the process of real-time monitoring and assessment of potential settlement and deformation of bridges during their use. During construction or operation, factors such as declining water levels, excessive foundation bearing capacity, and changes in geological structure can cause varying degrees of settlement in bridges. Excessive settlement of bridge piers can lead to bridge deck misalignment, uneven stress distribution, and even bridge instability.

[0003] The main purpose of bridge settlement monitoring is to promptly detect and address bridge settlement issues, ensuring the safety and stability of the bridge. Monitoring allows us to understand the deformation of the bridge under different environmental conditions, providing a scientific basis for bridge maintenance and management. Therefore, appropriate settlement detection devices are needed to accomplish this task. For convenience, digital settlement detection is generally used, requiring the control box to be installed on-site. However, long-term use of this device can easily damage the control box. Utility Model Content

[0006] As a further technical solution of this utility model, the side mounting plates are symmetrically distributed about the central axis of the protective cover, and two mounting holes are provided in the side mounting plates.

[0007] As a further technical solution of this utility model, the front end face of the protective cover is fixed with a glass window for observation, and the sliding groove is symmetrically distributed about the central axis of the positioning column.

[0008] As a further technical solution of this utility model, a sliding connection is formed between the slide groove and the slider, and a base plate is fixed at the bottom of the connecting rod.

[0009] As a further technical solution of this utility model, the slider is provided with a groove, and a ball is embedded in the groove.

[0010] As a further technical solution of this utility model, a connecting piece is fixed to the top of the positioning post, and a connecting hole is provided in the connecting piece.

[0011] As a further technical solution of this utility model, a retaining spring is connected to the back end of the connecting piece, and a washer is connected to the back end of the retaining spring.

[0012] As a further technical solution of this utility model, the retaining ring is distributed in a ring around the center of the gasket, and the gasket has a hole with the same diameter as the connecting hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this digital bridge settlement detection device not only improves the protection capability, but also improves the assembly capability and the active protection capability of the device.

[0014] (1) By assembling the position sensor in the connecting rod, the position sensor is used for digital settlement detection. The control box is assembled at the front end of the positioning column, and the protective cover is placed over the outside of the control box. The protective cover forms a cavity to accommodate the control box. During assembly, the mounting holes in the side mounting plate are fixed to the positioning column with bolts. A wiring hole communicating with the cavity is opened in the bottom of the protective cover. Therefore, the position of the wiring hole facilitates the wiring work, and the sealing ring design improves the sealing protection effect during wiring, thereby improving the overall protection capability.

[0015] (2) By fixing the connecting piece to the top of the positioning post and opening a connecting hole in the connecting piece, when the positioning post needs to be connected to the outer surface, a bolt connection can be used at the connecting hole. A retaining spring is used to connect the washer at the back end of the connecting piece, which serves as a cushion protection during connection and assembly, thereby improving the overall assembly capability.

[0016] (3) By opening the groove on both sides of the positioning post, the slider is slidably connected inside the groove. Therefore, after the positioning post is assembled, the two connecting rods extend above the settlement detection surface, and the base plate is located above the settlement detection surface. When the detection surface settles, the slider slides in the groove. At this time, the groove and the ball cooperate to roll and protect, thereby improving the activity protection capability.
