The invention relates to the field of hydraulic engineering equipment, and provides a pre-cleaning device for the inner wall of a water delivery engineering structure. The pre-cleaning device comprises a vehicle body, a high-pressure cleaning mechanism and an erasing brush, wherein the high-pressure cleaning mechanism and the erasing brush are arranged on the vehicle body; the high-pressure cleaning mechanism is provided with a first high-pressure spray head which can spray high-pressure water toward the inner wall of the water delivery structure; and the first high-pressure spray head and theerasing brush are arranged to cooperate with each other. The device can be used for pre-cleaning of the inner wall of the water delivery engineering structure before crack detection. The invention also provides a crack detection set for the inner wall of the water delivery engineering structure. The crack detection set comprises a crack detecting device and the pre-cleaning device for the inner wall of the water delivery engineering structure. The crack detection set can detect more accurately whether the inner wall of the water delivery engineering structure has cracks
Description
technical field [0001] The invention relates to the field of water conservancy engineering equipment, in particular to a device for pre-cleaning the inner wall of a water delivery engineering structure and a crack detection set. Background technique [0002] At present, aqueducts, inverted siphons, and water pipelines are the main structural types of large-scale water diversion projects. During long-term operation, these engineering structures are prone to surface cracks. Therefore, regular inspections of these structures are required for timely maintenance and reinforcement. However, because these engineering structures will adhere to the surface of the inner wall during operation, such as sediment, etc., it will bring certain difficulties to the surface detection. [0003] In view of this, the present application is proposed. Contents of the invention [0004] The invention provides a pre-cleaning device for the inner wall of a water delivery engineering structure, aimi...
