Description

Automatic early warning device of dam corridor escape canal discharge

Technical Field

The utility model relates to a flow monitoring technical field specifically is dam corridor escape canal discharge automatic early warning device.

Background

The water leakage inside the dam is generally drained downstream through galleries drains, the water level and corresponding flow in the drains constantly changing, and the dam can be dangerous if the flow increases sharply. In order to ensure the safety of the dam, the flow needs to be monitored regularly, and the emergency rescue is needed when the flow exceeds the expected set value.

At present, some domestic small reservoirs observe the water flow of the drainage ditch of the gallery of the dam, generally measure the water depth of the drainage ditch in the gallery by using a ruler with low cultural degree in local villages, then look up a water level-flow relation table of the drainage ditch, calculate the flow, are troublesome and labor-consuming, and cannot perform real-time early warning. The method is characterized in that the water flow of a drainage ditch of a dam corridor is automatically observed in China, a sensor is generally arranged in the drainage ditch, a water level signal in the ditch is remotely transmitted to a monitoring computer through a cable, and related calculation software in the computer calculates the flow according to a pre-input drainage ditch water level-flow relation. Because the project cannot be monitored on the computer, the operator can watch the project only by clicking the project when using the computer, the operation is not intuitive, cables are long, and the maintenance is inconvenient when signals fail. In addition, the corresponding early warning flow of the dam drainage ditch is different in different periods. If the reservoir operates at a high water level, most of the water leakage is normal, and the early warning flow needs to be set higher; the reservoir operates at a low water level, less water leakage is normal, and the early warning flow needs to be set lower.
