Sluice opening degree measurement method

Abstract

The invention discloses a method of measuring floodgate opening. The method comprises the steps of arranging a position switch along the position where a hoist drive gear is lifted or lowered, the position switch together with a counter of a measuring device composes a counting circuit to acquire the tooth number of the gears; the position acquires a position limit signal when the floodgate is fully opened or closed; when the floodgate is lifted or lowered, the measuring device transforms the rotation tooth number of the host drive gear to floodgate opening through opening calculation according to a tooth number signal, the position limit signal and a lifting or lowering signal. When the measuring device obtains the signals that the floodgate is fully opened or closed, the counter resets. The method of measuring floodgate opening is easy to measure, high in precision, less in error and is convenient and easy to operate, which is particularly suitable to measure the opening of dam floodgate.

Description

Gate opening measurement method technical field The invention relates to a method for measuring the opening of a gate, in particular to the measurement of the opening of a dam gate. Background technique At present, the gate height measurement method still adopts the conventional mode, that is, a measuring device is installed between the dam gate and the gate frame. The actual displacement of the measuring device corresponds to the gate opening value, and the dam gate is often hundreds of meters. Due to the disadvantages of large measurement error, inconvenient installation of measurement equipment, inconvenient maintenance and high cost, it cannot meet the requirements of dam gate control. Contents of the invention The object of the present invention is to provide a method for measuring the opening of a gate with convenient measurement, high precision and small error. The purpose of the present invention is achieved by implementing the following technical solutions: ...
