Problems solved by technology

The disadvantages of this method are: measurement and reading cannot be completed at the same time, and when taking out the caliper and measuring with a steel ruler, there are human errors, the measurement efficiency is low, and in the volute, the environment is dark, and the problem of the line of sight of the measurement personnel increases the human error. The accuracy is low, the operation is complicated, and the requirements for operators are high. At the same time, this method cannot meet the measurement requirements for different types of guide vanes.

Abstract

The invention relates to an angle-type guide vane opening degree measurement device, and the device comprises a digital display angle ruler. One end of one of two measuring arms of the digital displayangle ruler is hinged to one end of the other one of the two measuring arms. The two measuring arms are provided with calipers which extend out of the other ends of the measuring arms, and the end parts of the calipers are provided with sharp parts. The lengths of the two measuring arms are consistent, and the lengths of the parts, extending out of the measuring arms, of the two calipers are consistent. The device provided by the invention can directly read the value on the digital display angle ruler, completes the measurement and reading simultaneously, reduces the errors, is high in measurement efficiency, is simple in operation, is convenient to use, is high in measurement precision, and reduces the requirements for an operator.

Description

technical field [0001] The invention relates to an angle type guide vane opening measurement device. Background technique [0002] In the maintenance of various generator sets in hydropower plants, the existing measurement method for measuring the opening of the guide vane is: the maintenance personnel put the two ends of the caliper into the gap between the two guide vanes, adjust the opening angle of the caliper until the opening of the guide vane is measured Finally, take out the caliper and use a steel ruler to measure the distance between the measuring points of the caliper, which is the opening value of the guide vane. The disadvantages of this method are: measurement and reading cannot be completed at the same time, and when taking out the caliper and measuring with a steel ruler, there are human errors, the measurement efficiency is low, and in the volute, the environment is dark, and the problem of the line of sight of the measurement personnel increases the human e...
