Description

TECHNICAL FIELD

[0001] The utility model relates to the field of measurement technology, especially to a tension wire manual comparison measuring device. BACKGROUND

[0002] Tension wires and tension wire type horizontal displacement meters have been widely used in the field of dam safety monitoring. They are key facilities for monitoring dam deformation and are known for their high reliability. Tension wires are mainly used for concrete dam bodies to monitor their horizontal displacement, while tension wire type horizontal displacement meters are mainly applied to earth and rockfill dams to detect the horizontal displacement changes inside the dam body. Although automated observation technology has been introduced, manual observation is still an indispensable observation method for tension wires and tension wire type horizontal displacement meters. According to regulations, manual comparison measurement should be carried out at least once a month and at least 12 times a year to ensure data accuracy.

[0003] In traditional measurement technology, the use of tension wire and tension wire type horizontal displacement meter manual observation instruments often involves a series of inconveniences. Specifically, this observation method requires at least two people to cooperate: one person is responsible for holding the instrument for observation, while the other person needs to provide lighting. Due to the limitations of this operation method, instrument shaking is prone to occur during observation, leading to unstable measurement results. In addition, due to the difficulty in ensuring that the observation angle is completely vertical, this further increases the possibility of data error, thereby affecting the accuracy of measurement.
