Embodiment Construction

[0012] In this embodiment, the metal disk is fixed on the support of the runner. The axis line of the runner passes through the center of the metal disc and is perpendicular to the metal disc. The scale is engraved on the metal disc. The reading pointer is mounted coaxially with the pointer push rod on the metal disc and is coaxial with the wheel. The reading pointer and the pointer push rod are fixed together and can rotate around the axis of the runner synchronously. The reading pointer and the pointer push rod form 180°. The pointer push rod is L-shaped with a collar at the end. The wire rope for hoisting the lead fish passes through the collar.

[0013] When the wire rope is in the vertical position, the reading pointer points to the 0° scale on the disc.

[0014] When the lead fish enters the water, the deflection angle generated by the steel wire rope by the water impulse pushes the pointer push rod, and the reading pointer rotates with the pointer push rod, and the...

Abstract

The invention relates to a hydrographic measurement instrument, in particular to an instrument for measuring the declination of a measurement wire rope of a hydrologic bridge flow measurement vehicle to deviate the vertical direction. A hydrologic bridge flow measurement vehicle sounding declination reading disk arranged on the support of the runner of a lifting lead fish steel rope consists of a metal disk marked with scales, a reading pointer and a pointer push rod; wherein, the metal disk is fixed on the support of the runner; the reading pointer and the pointer push rod, coaxially arranged and fixed together, are coaxial with the runner and can synchronously move around the axis line of a runner shaft; the extremity of the L-shaped pointer push rod is provided with a lantern ring; the steel rope of the lifting lead fish runs through the lantern ring. The instrument is characterized by simple construction, little investment, strong practicality and convenient observation and installation and has the advantages that the instrument can be directly arranged on the existing equipment, directly observe the sounding inclination, correct the sounding and improve the flow measurement. When the sounding inclination is oversized, the instrument prompts to replace the lead fish.

Description

Technical field: [0001] The invention relates to a hydrological measuring instrument, in particular to an instrument for measuring the deviation angle of a steel wire rope from a vertical direction by a hydrological bridge measuring flow vehicle. Background technique: [0002] Article 3.3.2 of "River Flow Measurement Specifications" (GB50179-93), 3. Using lead fish for sounding, the deviation angle should be corrected when the deviation angle exceeds 10°; when the deviation angle is too large, a larger lead fish should be replaced . However, there is no instrument for observing the deviation angle on the current measuring vehicle of the hydrological bridge, and it is impossible to observe the deviation angle. Invention content: [0003] The invention is an instrument for measuring vehicle depth of a hydrological bridge, which can observe the angle at which the sounding steel wire rope deviates from the vertical direction due to the impulsive force of the water flow.
