A device for detecting water leakage of a gate and its control method

Abstract

The invention discloses a device for detecting water leakage of a gate, which belongs to the technical field of measurement and comprises a control module used for controlling the work of the device, a lifting module for fixing a signal collecting module and enabling the signal collecting module to be lifted, the signal collecting module used for collecting water leakage flow of the gate, a signal analyzing and processing module used for analyzing and processing a water leakage signal collected by the signal collecting module and an information display module used for displaying system operation and detection data. The invention further discloses a control method of the detecting device, the method can accurately measure fine water leakage condition of the gate and fully and timely feedback the position of gate water leakage and the condition of the gate water leakage to the information display module, and effectively ensures life safety of detecting personnel. Simultaneously, the device for detecting water leakage of the gate is convenient to operate and high in mechanical automation control degree and working efficiency.

Description

technical field [0001] The invention relates to a device and method for detecting water leakage of a gate, belonging to the technical field of measurement. Background technique [0002] Gates are the most common type of hydraulic structures. However, due to lax construction quality control and improper management and operation, there are common water leakage problems in gates. It has always been said that "ten gates and nine leaks". The water leakage of the gate not only affects the benefit of the project, but also brings inconvenience to the maintenance and repair of the buildings downstream of the lock chamber. And once the gate leaks, if it is not found in time, the post-processing will be difficult and the effect will not be good. Therefore, active measures must be taken in the early stage of the gate leak to prevent the gate from leaking. The first step in the early stage of water leakage is to detect the water leakage of the gate. [0003] In existing projects, the w...

Problems solved by technology

[0003] In existing projects, for the water level above the downstream water level of the sluice chamber, the leakage of the sluice can be directly observed by naked eyes. Frogman diving is needed, but frogmen are not professional inspectors, so the inspection often cannot fully reflect the real situation. At the same time, there are still many limitations in frogman diving detection, such as high cost of detection, limited range of detection, high risk of detection, etc.
