Description

Technical Field

[0001] This utility model relates to the field of water conservancy testing technology, and in particular to a crack detection device for water conservancy testing. Background Technology

[0002] The overall sturdiness of water conservancy-related structures directly affects their actual service life. To ensure the safety of water conservancy structures after completion, it is necessary to conduct on-site inspections using specialized crack detection devices.

[0003] For example, patent document CN217954343U discloses a multi-angle dam crack detection device for hydraulic testing. This device adjusts the transducer angle using an angle adjustment device, applies coupling agent to the bottom of the transducer using an applicator, and then uses the angle adjustment device to attach the bottom of the transducer to the crack for detection. The detection results are displayed on the main unit's screen, thus reducing the workload of workers and improving the equipment's detection efficiency. However, current detection devices require the transducer to be in close contact with the surface of the crack during use. This has certain drawbacks; if the surface of the crack being detected has slight protrusions or hard particles, the transducer cannot maintain close contact, leading to erroneous detection results and inaccurate detection.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-6As shown, a crack detection device for hydraulic testing includes a vehicle body 1. The vehicle body 1 includes a mounting plate 101. Support legs 102 are screwed to the four corners of the top of the mounting plate 101. Rollers 103 are mounted on the bottom of the support legs 102 to facilitate movement of the vehicle body 1. A handle 104 is screwed to the rear end of the top of the vehicle body 1. A detection host 105 is mounted on the handle 104. A camera assembly 2 is mounted on the bottom front end of the mounting plate 101. The camera assembly 2 transmits crack images to the detection host 105. Operators observe the cracks through the display screen on the detection host 105. The mounting plate 101 is equipped with a detection mechanism 7 and a coating mechanism 8. The coating mechanism 8 is used to apply the coating to the cracks. Mechanism 7 applies coupling agent. A grinding mechanism 3 is provided on the rear side of camera assembly 2. The grinding mechanism 3 includes a lifting frame 301, which is slidably mounted on the mounting plate 101 in the vertical direction. A rotating shaft 302 is rotatably connected to the lifting frame 301. A grinding disc 303 is fixedly connected to the bottom end of the rotating shaft 302. The top end of the rotating shaft 302 passes through the mounting plate 101 and is fixedly connected to a lifting gear 304. A cylinder 305 is fixedly connected to the bottom of the mounting plate 101. The output shaft of the cylinder 305 is fixedly connected to the bottom end of the lifting frame 301. The cylinder 305 drives the lifting frame 301 to move up and down, so that the grinding disc 303 can contact the crack surface and grind the surface protrusions.

[0026] A blowing mechanism 5 is provided on the rear side of the polishing mechanism 3. An air supply mechanism 4 is provided on the top of the blowing mechanism 5 to provide air power to the blowing mechanism 5.

A detection mechanism 7 is provided on the rear side of the blowing mechanism 5. A coating mechanism 8 is provided on the rear side of the detection mechanism 7.

[0027] The air supply mechanism 4 includes a rotating pipe 401, which passes through the mounting plate 101 in the vertical direction and is rotatably connected to the mounting plate 101. A fan blade 402 is fixedly connected inside the rotating pipe 401, and a gear ring 403 is fixedly connected to the outer wall of the rotating pipe 401. The gear ring 403 meshes with the lifting gear 304. The rotating pipe 401 drives the fan blade 402 to rotate, and the fan blade 402 blows air downward. At the same time, the gear ring 403 drives the lifting gear 304 to rotate, causing the grinding disc 303 to rotate for grinding. This allows grinding and blowing to occur simultaneously. The thickness of the gear ring 403 is greater than the thickness of the lifting gear 304, ensuring that the lifting gear 304 remains in mesh with the gear ring 403 even when it moves up and down a certain distance.

[0028] The air blowing mechanism 5 includes a connecting shell 501, which is rotatably connected to the bottom of the rotating tube 401. An air blowing pipe 502 is fixedly connected to the bottom of the connecting shell 501. The rotating tube 401 is connected to the air blowing pipe 502 through the connecting shell 501. The bottom of the air blowing pipe 502 is provided with multiple air blowing ports. The airflow generated by the rotation of the fan blade 402 enters the air blowing pipe 502 through the connecting shell 501. Then the airflow is blown out through the air blowing ports at the bottom of the air blowing pipe 502 to blow away the dust in the crack. Fixing plates 503 are fixedly connected to both sides of the air blowing pipe 502. The fixing plates 503 are fixedly connected to the bottom of the mounting plate 101.

[0029] The power mechanism 6 includes a bracket 601, which is connected to the mounting plate 101 by screws. A power motor 602 is connected to the bracket 601 by bolts. A power gear 603 is fixedly connected to the output end of the power motor 602, and the power gear 603 meshes with the gear ring 403.

[0030] The testing mechanism 7 includes an electric telescopic rod 701, which is connected to the bottom of the mounting plate 101 by screws. The output end of the electric telescopic rod 701 is fixedly connected to a mounting frame 702. A flip motor 703 is bolted to one side of the mounting frame 702. A flip block 704 is fixedly connected to the output end of the flip motor 703. The flip block 704 is rotatably connected inside the mounting frame 702. A transducer 705 is fixedly connected to the bottom of the flip block 704.

[0031] The coating mechanism 8 includes a material container 801, which is fixedly connected to the top of the mounting plate 101. A hydraulic cylinder 802 is fixedly connected to the top of the material container 801, and a guide pipe 803 is fixedly connected to the bottom of the material container 801.

[0032] Working principle: During use, the operator pushes handle 104 to move vehicle body 1. Camera component 2 transmits the image of the crack to detection host 105. The operator observes the crack through the display screen on the detection host 105. When a protrusion is encountered at the crack, the grinding disc 303 is moved above the protrusion. Cylinder 305 drives lifting frame 301 to move down. Lifting frame 301 drives rotating shaft 302 and grinding disc 303 to move down. Through power motor 602, power gear 603 rotates. Power gear 603 drives gear ring 403 and rotating tube 401 to rotate. Gear ring 403 drives lifting gear 304 to rotate. Lifting gear 304 drives grinding disc 303 to rotate through rotating shaft 302. Grinding disc 303 then rotates against the protrusion. The material is polished to make the crack surface smooth. At the same time, the rotating tube 401 drives the fan blade 402 to rotate and generate airflow. The airflow enters the blowing tube 502 downward and is blown out from the blowing port at the bottom of the blowing tube 502, blowing away the dust at the crack. Then the transducer 705 moves to the detection position. The flipping motor 703 drives the flipping block 704 to rotate. The flipping block 704 drives the transducer 705 to rotate, so that the detection surface of the transducer 705 is aligned with the guide tube 803. The hydraulic cylinder 802 squeezes the inner coupling agent of the material box 801 from the guide tube 803. After the transducer 705 is coated with coupling agent, it is rotated to a vertical position. Then the electric telescopic rod 701 drives the mounting bracket 702 to move down, so that the transducer 705 moves down and sticks to the crack surface for detection.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
