Abstract

The invention discloses a waterproof and dustproof apparatus of a vertical plumb coordinatograph and an installation method thereof. The apparatus comprises a box body and a cover plate, wherein the box body and the cover plate are in a full-transparent mode. The box body has a U-shaped structure and clamp grooves B are formed in the tops of the two sides. The cover plate is in an inverted-U shape and the two sides of the bottom are inserted into the clamp grooves B. A vertical cylinder that is arranged vertically is fixedly connected to the middle part inside the box body; a rectangular hole corresponding to the vertical cylinder is formed in the middle part of the top end of the cover plate; a clamp groove A matching the top end of the vertical cylinder is formed around the rectangular hole; and the top end of the vertical cylinder is inserted into the clamp groove A. According to the invention, a vertical plumb coordinatograph is fixedly installed in a sealed apparatus and thus the whole vertical plumb coordinatograph can be protected well, thereby effectively eliminating adverse factors like external moisture, dust and dropped slag stones and providing a long-term stable working environment for the vertical plumb coordinatograph.

Description

technical field [0001] The invention relates to the field of water conservancy and hydropower engineering dam safety monitoring, in particular to a waterproof and dustproof device for a vertical line coordinate meter and an installation method thereof. Background technique [0002] At present, most of the vertical line coordinate instruments are based on the principles of photoelectric induction and capacitance, and use a non-contact method to monitor the horizontal displacement and deflection of the dam in conjunction with the vertical line installed on the dam body. In most cases, it has the ability to observe It has the advantages of high precision, good stability, and automation, so it has been widely used. [0003] Usually, the vertical line coordinate instrument adopts a fully sealed design, and its sensing parts have been specially protected. It can work reliably for a long time in an environment with a relative humidity of 95%. 1. For the coordinate instrument of th...
