Description

Technical Field

[0001] This utility model relates to the field of bridge inspection technology, specifically to a detection device for bridge water seepage. Background Technology

[0002] A bridge is a road erected at a height to provide transportation. A bridge generally consists of a superstructure, substructure, and ancillary structures. The superstructure mainly refers to the bridge span structure and bearing system; the substructure includes abutments, piers, and foundations; and ancillary structures include approach slabs, tapered slopes, revetments, and diversion works. According to structural systems, bridges are classified into four basic systems: beam bridges, arch bridges, rigid frame bridges, and suspension bridges. During bridge construction, the water permeability of a bridge is an important indicator of its stability. Water permeability testing requires installing a sealing device on the bridge, injecting water into the device, and measuring the change in water volume over a period of time to determine the bridge's water permeability.

[0003] Existing bridge surfaces are not perfectly level; the bridge decks have some inclination. However, most current detection devices are not convenient for adjusting the tilt angle of the sealing cover, making them unusable on sloping surfaces and thus impractical. Therefore, this invention provides a detection device for bridge seepage. Utility Model Content

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a detection device for bridge seepage, which has the following beneficial effects:

[0015] This device for detecting bridge seepage utilizes a combination of a rotating shaft, a sealing cover, a vertical plate, a drive motor, a threaded rod, a moving block, a connecting rod, a fixing frame, a liquid storage cylinder, a hose, a chute, gears, springs, a toothed plate, and a pressing plate. During use, the angle of the sealing cover is adjusted according to the road surface inclination at the measurement point. The drive motor then rotates the threaded rod, which in turn moves the moving block downwards along the interior of the vertical plate. This, in turn, moves the connecting rod downwards, pushing the support frame and bringing the sealing cover into contact with the bridge surface. Water from the liquid storage cylinder then flows into the sealing cover through the hose. The level of the liquid in the storage cylinder indicates the bridge's seepage performance, thus effectively detecting inclined road surfaces on bridges and significantly improving the device's practicality.

Then, the drive motor 6 drives the threaded rod 7 to rotate. At this time, the threaded rod 7 will drive the moving block 8 to move downward along the inside of the upright plate 5, and then drive the connecting rod 9 to push the support frame 2 downward and make the sealing cover 4 stick to the bridge surface. Then, the water in the liquid storage cylinder 11 flows into the sealing cover 4 through the hose 12. Then, the water seepage performance of the bridge is known according to the liquid level in the liquid storage cylinder 11, thereby playing a role in detecting the inclined road surface on the bridge and effectively improving the practicality of the device. Both ends of the toothed plate 16 are slidably connected to the inner wall of the slide groove 13. The surface of the liquid storage cylinder 11 is provided with a scale strip 18.

This, in turn, drives the threaded rod 7 to rotate via the drive motor 6. The threaded rod 7 then causes the moving block 8 to move downwards along the interior of the vertical plate 5, which in turn drives the connecting rod 9 to push the support frame 2 downwards, bringing the sealing cover 4 into contact with the bridge surface. Water from the liquid storage cylinder 11 then flows into the sealing cover 4 through the hose 12. The bridge seepage performance is then determined based on the liquid level in the liquid storage cylinder 11, thus effectively detecting inclined road surfaces on bridges and significantly improving the device's practicality.
