Description

Technical Field

[0001] This utility model relates to the field of underwater health monitoring of pier-type hydraulic structures such as bridge piers, and in particular to an installation bracket suitable for underwater safety monitoring of bridge piers. Background Technology

[0002] Bridges are an important part of transportation infrastructure, playing a vital role in people's travel and freight transport, especially long bridges that span rivers and seas.

[0003] In recent years, bridge damage caused by water has become a globally recognized leading cause of bridge collapse and failure. Furthermore, the increasing frequency of extreme weather events, the aging of bridges, and river development and management have all contributed to the rising trend of bridge water-related accidents. Bridge water-related accidents are generally characterized by their suddenness, insidious nature, and thoroughness, making the deployment and systematic implementation of an underwater safety and health monitoring system for bridges a growing trend.

[0004] Statistical surveys have revealed that underwater scouring and flooding are two significant hydrological factors contributing to bridge damage caused by water. Therefore, bridge management units primarily focus on establishing underwater pier scouring and flood monitoring systems to gain real-time insights into pier scouring dynamics and hydrological information, thereby optimizing bridge management and maintenance.

[0005] New bridges typically have designated locations for underwater sensor installations from the design phase. However, older bridges require external underwater sensor installation platforms on their piers. Drilling holes in the pier body or underwater abutment increases the risk of structural damage. Therefore, a suitable mounting bracket for underwater safety monitoring of bridge piers needs to be designed to provide an installation platform for underwater monitoring sensors and avoid damaging the bridge structure.

Detailed Implementation

[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1 , Figure 2 , Figure 3 The present invention relates to an installation bracket for underwater safety monitoring of bridge piers, comprising a first mounting base plate 1, pull ring screws 2, flatness adjustment rods 3, a second mounting base plate 4, a first vertical mounting rod 5, and a supporting diagonal rod 6; the first mounting base plate 1 is connected to two pull ring screws 2, the first mounting base plate 1 is provided with four flatness adjustment rods 3, the first mounting base plate 1 is sequentially connected to the second mounting base plate 4 and the first vertical mounting rod 5; a supporting diagonal rod 6 is provided between the second mounting base plate 4 and the first vertical mounting rod 5.

[0036] like Figure 4 , Figure 5 , Figure 6 , Figure 7, the first mounting base plate 1 of the present utility model is a "C"-shaped member. The horizontal plate 11 on the upper part of the first mounting base plate 1 is provided with two first pull rings 12, and one internal thread hole 13 penetrating through the upper and lower horizontal plates 11 is arranged on the outside of each first pull ring 12; on the inner side of the vertical plate 14 of the first mounting base plate 1, three first threaded columns 15 and four internally penetrating second internal thread holes 16 are provided. The second internal thread holes 16 are arranged on the outside of the three first threaded columns 15 and on the inner side of the internal thread holes 13 of the upper and lower horizontal plates 11. The horizontal spacing of the second internal thread holes 16 is greater than the sum of the length of the second mounting base plate 4 and the thickness of the first vertical mounting rod 5. Four non-penetrating reserved holes 17 are arranged on the outside of the vertical plate 14, and the geometric center coincides with the geometric center of the second internal thread holes 16 on the inner side of the vertical plate 14 of the "C"-shaped member; the first pull rings 12, the internal thread holes 13, the first threaded columns 15, the second internal thread holes 16, and the reserved holes 17 are symmetrically arranged along the vertical center line in the length direction of the "C"-shaped member.

[0037] As Figure 8 , Figure 9 , the pull ring screw 2 of the present utility model includes a second pull ring 21 and a second threaded column 22. The length of the second threaded column 22 is greater than the height of the first mounting base plate 1, and a through hole 23 is provided at the tail of the second threaded column 22; two pull ring screws 2 are matched with the two internal thread holes 13 on the outside of the first pull rings 12. Further enhance the stiffness of the first mounting base plate 1. Both ends of cables such as steel wires can be respectively tied to the pull rings (the first pull rings 12 and the second pull rings 21) of the first mounting base plate 1 and the pull ring screws 2, and the tightness of the cable can be adjusted by using the through hole 23, so as to have the ability to be tightly fixed to pier-shaped hydraulic structures such as bridge piers.

[0038] As Figure 10 , Figure 11 , the flatness adjusting rod 3 of the present utility model is a threaded column structure, and a flat and widened screw head is provided at the top of the threaded column, which is matched with the reserved holes 17 arranged on the outside of the vertical plate 14. When the flatness adjusting rod 3 is fully tightened with the reserved holes 17 on the outside of the vertical plate 14, a flat contact surface can be formed. Adjust the height of the flatness adjusting rod 3 to adapt to the uneven surface of pier-shaped hydraulic structures such as bridge piers, so that stable着力点 can be formed when the first mounting base plate 1 is adjusted up and down and left and right, ensuring that the first mounting base plate 1 has the ability to always maintain a vertically downward state.

[0039] As Figure 12 , Figure 13 , Figure 14The second mounting base plate 4 of this utility model is a reinforced L-shaped component. Each of the two panels of the L-shaped component has one circular opening 41 and two arc-shaped openings 42, which can be matched and fixed with the threaded post 15 on the inner side of the vertical plate 14 by nuts. A pre-reserved threaded hole 43 is provided on the outer edge of the second mounting base plate 4 away from the first mounting base plate 1. The two arc-shaped openings 42 can finely adjust the relative fixed positions of the first mounting base plate 1 and the second mounting base plate 4, and the first mounting vertical rod 5, realizing three-dimensional adjustment of the external mounting platform at the end of the first mounting vertical rod 5 in the left, right, front, and back spaces.

[0040] like Figure 15 , Figure 16 The first vertical mounting rod 5 of this utility model includes a rectangular flat plate 51, a gradient section 52, and a cylindrical vertical rod 53 connected in sequence. The rectangular flat plate 51 has three threaded post 54s, which are matched with one circular opening 41 and two arc-shaped openings 42 and fixed by nuts. The bottom of the cylindrical vertical rod has a built-in threaded hole 55 for suspending a threaded monitoring sensor or mounting platform. The bottom of the cylindrical vertical rod 53 also has a built-in threaded hole 55. The left and right sides of the tail section of the cylindrical vertical rod 53 have mounting planes 56 with threaded holes 57, allowing for the installation of an external mounting platform as needed.

[0041] The supporting diagonal rod 6 of this utility model connects and fixes the reserved threaded hole 43 on the stiffening plate of the second mounting base plate 4 with the built-in threaded hole 57 on the side mounting plane 56 of the tail section of the first vertical mounting rod 5 through the threaded post; forming an organically integrated whole, enhancing the rigidity of the first vertical mounting rod 5 and reducing the vibration of the first vertical mounting rod 5 caused by water flow.

[0042] This invention provides an installation bracket specifically designed for underwater safety monitoring of pier-type hydraulic structures such as bridge piers. The bracket is capable of vertical and horizontal adjustment, as well as three-dimensional spatial adjustment (left-right and front-back), flexibly adapting to different monitoring needs. It makes underwater safety monitoring possible for existing bridge piers and other pier-type hydraulic structures that have not been pre-planned for underwater safety monitoring platforms, and has significant practical value.
