Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a fast flow rate water level measuring device for water conservancy project detection. Background Art

[0002] Water level refers to the elevation of the free water surface of a water body above a fixed base surface. The role of water level measurement is to directly provide data with independent use value for water conservancy, water transportation, flood control, and waterlogging prevention. It also provides indirect application data for the derivation of other hydrological data. After the completion of a water conservancy project, the staff needs to measure the water level, so a fast-flow water level measuring device is needed for water conservancy project inspection.

[0003] Currently, most of the existing fast-flow water level measuring devices used in water conservancy project inspections use radar water level detectors to detect water levels. However, when encountering foggy weather, the fog will affect the detection of the radar water level detector, resulting in inaccurate detection results.

[0004] Therefore, most of the currently available fast-flow water level measuring devices for water conservancy project inspections use radar water level detectors to detect water levels. However, when encountering foggy weather, the fog will affect the detection of the radar water level detector, resulting in inaccurate detection results. A fast-flow water level measuring device for water conservancy project inspections can be designed. By setting a winch, a connecting rope, a pulley, a lifting rod, a float, a connecting plate, a lifting plate and a laser rangefinder, when encountering foggy weather, the winch is started, the winch can release the connecting rope, and the lifting rod slides downward under the action of gravity. When the float at the lower end of the lifting rod floats on the water surface, the winch can be stopped, and the lifting rod can drive the lifting plate to move downward through the connecting plate. The laser rangefinder can detect the height of the lifting plate, and then the water level can be detected, avoiding interference from external fog. Utility Model Content

A lifting plate 23 is provided inside the installation box three 20, and a connecting plate 22 is provided inside the through slot 21. The right side of the connecting plate 22 is fixedly set on the left side of the lifting rod 18, and the left side of the connecting plate 22 is fixedly set on the right side of the lifting plate 23. A laser rangefinder 24 is fixedly provided on the top of the interior of the installation box three 20. When foggy weather occurs, the winch 13 is started, the winch 13 can release the connecting rope 14, and the lifting rod 18 slides downward under the action of gravity. When the float 19 at the lower end of the lifting rod 18 floats on the water surface, the winch 13 can be stopped, and the lifting rod 18 can drive the lifting plate 23 to move downward through the connecting plate 22. The laser rangefinder 24 can emit laser, which is reflected by the lifting plate 23 and received by the laser rangefinder 24. The laser rangefinder 24 can thereby detect the height of the lifting plate 23 and then detect the water level.

[0023] See also Figure 2-Figure 3 In this embodiment, a radar water level detector body 25 is installed at the inner bottom of the installation box 12. The radar water level detector body 25 is located on the right side of the installation box 2 17.

[0024] See also Figure 1-Figure 4In this embodiment, a top plate 3 is fixedly provided on the top of the support rod 2, a partition 4 is fixedly provided on the inner upper end of the support rod 2, a motor 5 is fixedly provided on the top of the partition 4, and the output end of the motor 5 passes through the top plate 3 and is fixedly provided on the bottom of the rotating plate 6. An annular groove 7 is provided on the top of the top plate 3, and an annular plate 8 is fixedly provided on the bottom of the rotating plate 6. The lower end of the annular plate 8 is provided inside the annular groove 7. When the motor 5 is started, the motor 5 can drive the rotating plate 6 to rotate, and the rotating plate 6 can thereby drive the installation box 12 to rotate through the installation column 9 and the installation rod 10.

[0026] During operation, when it is necessary to detect the water level, the motor 5 is started, and the motor 5 can drive the rotating plate 6 to rotate. The rotating plate 6 drives the installation box 12 to rotate through the installation column 9 and the installation rod 10, and the installation box 12 is rotated above the water surface. At this time, the radar water level detector body 25 can detect the water level. When encountering foggy weather, the winch 13 is started, the winch 13 can release the connecting rope 14, and the lifting rod 18 slides downward under the action of gravity. When the float 19 at the lower end of the lifting rod 18 floats on the water surface, the winch 13 can be stopped, and the lifting rod 18 can drive the lifting plate 23 to move downward through the connecting plate 22. The laser rangefinder 24 can emit a laser, and the laser is reflected by the lifting plate 23 and received by the laser rangefinder 24. The laser rangefinder 24 can thereby detect the height of the lifting plate 23, and thus detect the water level.

[0027] Through the above steps, by setting the winch 13, connecting rope 14, pulley 16, lifting rod 18, float 19, connecting plate 22, lifting plate 23 and laser rangefinder 24, when encountering heavy fog, the winch 13 is started, the winch 13 can release the connecting rope 14, and the lifting rod 18 slides downward under the action of gravity. When the float 19 at the lower end of the lifting rod 18 floats on the water surface, the winch 13 can be stopped, the lifting rod 18 can drive the lifting plate 23 to move downward through the connecting plate 22, and the laser rangefinder 24 can detect the height of the lifting plate 23, and then detect the water level, avoiding the interference of external fog, so as to solve the problem that most of the existing fast flow rate water level measuring devices for water conservancy project detection use radar water level detectors to detect water level, but when encountering heavy fog, the fog will affect the detection of the radar water level detector, thereby causing inaccurate detection results.
