Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy engineering equipment, and in particular relates to a water conservancy engineering gate quality detection device. Background Art

[0002] As an important equipment for controlling water flow, regulating water level and ensuring the safety of water conservancy facilities, the quality inspection of water conservancy project gates is of vital importance. With the continuous development of water conservancy projects and the continuous advancement of technology, the quality requirements for gates are getting higher and higher. In order to ensure the stable operation of gates in various complex environments, advanced and reliable detection devices must be used to conduct comprehensive and accurate quality inspections on gates.

[0003] At present, the quality inspection of water conservancy project gates mainly relies on traditional inspection methods, such as visual inspection, manual measurement and simple mechanical performance testing. Although these methods can detect problems with gates to a certain extent, they have limitations such as low inspection efficiency, low accuracy, and the inspection results are easily affected by human factors.

[0004] The patent with the patent announcement number CN118565753B discloses a water conservancy project gate quality detection device and its detection method, which relates to the field of water conservancy engineering technology.

When the present application is used, the gate is vertically installed in the gate cavity, the push plate slides back and forth in the water storage chamber and the stroke gradually increases, and water is continuously added to the water storage chamber.
