Description

Technical Field

[0001] This utility model belongs to the field of bridge settlement monitoring technology, specifically relating to a wireless settlement monitoring device for underwater bridges. Background Technology

[0002] A bridge in water mainly consists of several parts, including the bridge body, piers, abutments, and foundations. The structural forms of bridges include continuous beams and simply supported beams. Regardless of the structural form, the settlement of the piers will affect the bridge body. For continuous beams, when a pier settles, the internal forces of the continuous beam will be redistributed. The load originally borne by the settled pier will be partially transferred to the adjacent piers and the bridge body. Thus, the synergistic effect of the entire structure resists the impact of settlement. Therefore, the bridge body will not deform immediately. Traditional settlement monitoring methods mostly utilize this characteristic of continuous beams to monitor the piers.

[0003] Currently, in practical applications, bridge piers may settle vertically while simultaneously displacing horizontally. However, traditional settlement monitoring methods for bridge piers mostly only consider the vertical settlement, resulting in a single function, a narrow range of applications, and poor actual performance.

[0004] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0005] The purpose of this invention is to overcome the problems of traditional settlement monitoring methods for bridge piers being limited in function, narrow in application scenarios, and unsatisfactory in actual use, and to provide a wireless settlement monitoring device for underwater bridges.

The center of the cover has a circular hole smaller than the diameter of the ball head, allowing the free end of the pendulum to move in any direction. The tension / compression sensing mechanism connects the main measuring arm and the auxiliary measuring arm as a whole. When the pier experiences settlement in both vertical and horizontal directions, the measuring arm is stretched and tilts along with the pier. When the measuring arm is stretched to the settlement warning length, it sends a warning message remotely to the terminal.

[0008] In the water bridge wireless settlement monitoring device, preferably, the edge of the cover extends transversely with a positioning plate to fix the positioning plate with the bridge body bottom surface or the pier top surface through bolts.

[0009] Preferably, the lower end of the main measuring arm is centrally connected with a guide table;

[0012] Preferably, the tension and pressure sensing mechanism comprises a position correcting plate, a pressing plate and a position correcting arm, the position correcting plate is fixedly sleeved on the outside of the auxiliary measuring arm and located above the guide table.

[0013] The distance between the position correcting plate and the guide table is a safe measurement distance of the pier settlement.

[0032] The main measuring arm 2 and the auxiliary measuring arm 3 both include: a ball head 4 and a swing rod 5, the ball head 4 is centrally fixed and connected to the fixed end of the swing rod 5, so that the ball head 4 is covered in the cover through the cover 1, the cover 1 is semicircular, and the inside of the cover 1 is a circular cavity, the center of the cover 1 is provided with a circular hole smaller than the diameter of the ball head 4, so that the free end of the swing rod 5 can move in any direction, wherein the edge of the cover 1 extends transversely with a positioning plate 6, so that the positioning plate 6 is fixed with the bottom surface of the bridge body or the top surface of the pier through bolts.

[0033] The lower end of the main measuring arm 2 is centrally fixed and connected with a guide table 7, and the upper end of the auxiliary measuring arm 3 is centrally fixed and connected with a diameter expansion plate 8 to expand the diameter of the auxiliary measuring arm 3, the diameter expansion plate 8 and the guide table 7 are circular and have the same size, wherein the guide table 7 is thicker so as to accommodate a wireless alarm button 9 in the inside, and the upper surface of the guide table 7 protrudes outwardly with a pair of pressing blocks 10, the two pressing blocks 10 are symmetrically arranged on the two sides of the main measuring arm 2, and the bottom of the pressing block 10 is connected with the wireless alarm button 9, when the pressing block 10 is pressed, the wireless alarm button 9 will be triggered.

[0034] The tension and compression sensing mechanism connects the main measuring arm 2 and the auxiliary measuring arm 3 into one, when the pier occurs settlement in vertical and horizontal directions, the measuring arm is elongated while following the inclination of the pier, and when the measuring arm is elongated to the settlement warning length, the terminal remote alarm information is sent, the terminal is a mobile phone or a computer, so that the staff can know the settlement information of the pier in time, specifically, the tension and compression sensing mechanism includes: a position correcting plate 11, a pressing plate 12 and a position correcting arm 13, the position correcting plate 11 is fixedly sleeved on the outside of the auxiliary measuring arm 3 and located above the guide table 7, so that the distance between the position correcting plate 11 and the guide table 7 is the safe measurement distance of the pier settlement, the pressing plate 12 is movably sleeved on the outside of the auxiliary measuring arm 3, and the pressing plate 12 moves downward along the axial direction of the auxiliary measuring arm 3 along with the settlement of the pier.

[0035] The position correcting arm 13 is parallel to the side of the measuring arm, and is actually a threaded rod, and three of them are evenly distributed around the auxiliary measuring arm 3 to enhance stability. The lower end of the position correcting arm 13 is rotatably installed on the diameter expansion plate 8 through a bearing, and the bearing is fixedly embedded in the diameter expansion plate 8. The position correcting arm 13 is in interference fit with the bearing. The upper end of the position correcting arm 13 extends above the position correcting plate 11 after sequentially penetrating the guide table 7 and the pressing plate 12.
