Reservoir level tester for pumped storage power plant and installation method of reservoir level tester

Abstract

The invention discloses a reservoir level tester for a pumped storage power plant and an installation method of the reservoir level tester. The reservoir level tester comprises a test pipe, a floater, a stay cord and a level test device, wherein the test pipe perpendicular to a dam axis is mounted on a face of an upstream dam slope surface of a concrete-faced rockfill dam in the reservoir of the pumped storage power plant; an air vent is formed in the top end of the test pipe; a pipe orifice in the bottom of the test pipe is open; the floater is arranged on the water surface in the test pipe; the stay cord connected with a reservoir level sensing device is fastened at the top end of the floater; the reservoir level sensing device is mounted on a wave wall at the dam top; a rope winding type water level sensor and an electric hoist are fixed side by side on the top surface of a base of the reservoir level sensing device; and when the stay cord drives a rope winding disc to rotate, a switch wheel magnet ring switches the magnetic force lines of two magnetic-sensing elements after the transmission of a spindle and a gear set, and the two magnetic-sensing elements output sensing signals of the reservoir level. The reservoir level tester has the characteristics of wide range, high precision, high speed, reliability in operation, convenience in installation and capability of testing the level on an inclined plane of the dam slope, and is an instrument capable of outputting the reservoir level of the pumped storage power plant in real time.

Description

technical field [0001] The invention relates to a tester specially used for testing the water level of a pumped storage power station reservoir and a method for installing the same, in particular to a water level tester for a pumped storage power station reservoir and a method for installing the same. Background technique [0002] At present, methods such as scales, fixed contacts, ultrasonic waves, and pressure sensors are commonly used to test the water level of reservoirs. Some of these methods are visual tests, and some cannot meet the requirements in terms of accuracy or range, so their applications are limited. Contents of the invention [0003] Aiming at the deficiencies of the existing ordinary reservoir water level test methods, the present invention proposes a pumped storage power station reservoir water level tester and its test method, which can meet the requirements of large reservoir water level rise and fall, fast water level change speed, and high test accur...
