Description

Technical Field

[0001] The utility model relates to the technical field of measuring rods, in particular to a measuring rod for underwater hydraulic structures. Background Art

[0002] At present, a measuring rod for underwater hydraulic structures is usually used to measure the size, depth and position of underwater structures for construction, maintenance and monitoring. The measuring rod is usually marked with a length scale for measuring the size and depth of underwater structures. These markings need to be clearly visible and have good readability in an underwater environment, but the existing measuring rods on the market have only fixed lengths and cannot be extended, which restricts the type of measurement and affects the accuracy of the measurement.

[0003] Chinese utility model patent CN217110730U discloses a measuring rod for underwater hydraulic structures. The device places a first clamping plate so that the first clamping plate clamps one side of the measured object, and can push the second clamping plate to clamp the measured object. The width or height of the measured object can be checked through the scale line, which solves the problem that the existing measuring rod needs to be placed on the building, and then the scale on the surface of the measuring rod of the building is compared with the naked eye. When measuring the building objects, large errors will occur, reducing the measurement accuracy. However, the device has only a fixed measurement distance and cannot adjust the length of the measuring rod according to the size of the measured building, which affects the use effect.
