Description

Technical Field

[0001] The present invention relates to the technical field of concrete pipe detection, and specifically to a concrete pipe damage detection device. Background Art

[0002] Concrete pipes are pipes used for transporting liquids or gases, and their materials are mainly concrete. Concrete pipes are usually used in various engineering fields, such as construction, water conservancy, drainage, sewage disposal, etc. The characteristics of concrete pipes are strong structure, good durability, and the ability to adapt to various environmental conditions. After a period of use, a concrete pipe needs to be detected for damage by a damage detection device.

[0003] Currently, when detecting concrete pipes in the market, there is a lack of cleaning of the inner wall of the pipe. Therefore, during detection, dust covers the damaged cracks, resulting in the inability to take pictures of the cracks for detection, thus leading to poor detection effects for damaged cracks. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a concrete pipe damage detection device, which solves the problems that during the damage detection of concrete pipes, dust and impurities cover the damaged cracks of the concrete pipes, resulting in inaccurate detection and low detection effects.

[0006] Preferably, a water tank is fixedly connected to the inner wall of the first box body. A water pump is fixedly connected to the right end of the water tank. The water outlet of the water pump is rotatably connected to the left end of the connecting cylinder and penetrates through it.

[0007] Preferably, a second limiting plate is fixedly connected to the middle of the top end of the first box body. A double-shaft motor is fixedly connected to the inner wall of the second limiting plate. Driving shafts are fixedly connected to the driving ends of the double-shaft motor. A second gear and a first gear are respectively fixedly connected to the opposite ends of the driving shafts.

[0008] Preferably, a first toothed ring is fixedly connected to the left side of the outer diameter of the connecting cylinder. The outer diameter of the first toothed ring is meshed with the outer diameter of the second gear. A second toothed ring is fixedly connected to the right side of the outer diameter of the rotating shaft. The outer diameter of the second toothed ring is meshed with the outer diameter of the first gear.

[0009] Preferably, first limiting plates are fixedly connected to both the left and right sides of the top end of the first box body. The inner walls of the first limiting plates are rotatably connected to the outer walls of the driving shafts.

[0010] Preferably, a plurality of electric push rods are fixedly connected to the middle of the outer wall of the first box body.

A plurality of fixing plates are fixedly connected to both the left and right sides of the outer end of the placing plate.

[0011] Preferably, telescopic rods are fixedly connected to both the left and right sides of the outer wall of the first box body corresponding to the electric push rods. The outer ends of the telescopic rods are fixedly connected to the inner ends of the placing plates.

[0012] Preferably, the dust concentration sensor is electrically connected to the second terminal controller, and the first terminal controller is electrically connected to the high-definition camera.

[0013] Working principle: First, place this detection device inside the concrete pipe. Then start the electric push rod to move the placement plate outward until the hub motor mechanism contacts the inner wall of the concrete pipe. Thus, it can detect concrete pipes of different sizes. And start the hydraulic rod to push the slider to move to the right. The slider drives one end of the connecting rod to move to the right. Since the length of the connecting rod remains unchanged, it will push the sliding rod outward, so that the cleaning plate contacts the inner wall of the concrete pipe. Thus, it can clean concrete pipes of different sizes, improving the practicability of this device. Then move through the hub motor mechanism to the inner wall of the concrete pipe. Then start the double-shaft motor to drive the drive shaft to rotate. The drive shaft drives the first gear and the second gear to rotate. The second gear drives the first toothed ring to rotate. The first toothed ring drives the connecting cylinder to rotate. The cleaning plate is driven to rotate through the connecting cylinder, and the inner wall of the concrete pipe can be cleaned. During the cleaning process, dust will be generated. At this time, start the exhaust fan to generate suction. Then, the dust is sucked into the dust collection box through the dust suction cover and the right half of the connecting cylinder. When absorbing the dust, the dust concentration sensor can detect the dust concentration. The detected dust concentration data is transmitted to the terminal controller II. The suction of the exhaust fan is controlled by the terminal controller II. When the dust concentration is too high, the suction of the exhaust fan will also be relatively large, preventing the concentration from being too high and the dust not being processed in time, resulting in the dust covering the inner wall of the concrete pipe again, thus avoiding affecting the detection of cracks in the concrete pipe. After cleaning and dust suction, pump the water in the water tank out through the water pump. The water is sprayed out through the left half of the connecting cylinder and the atomizing nozzle. The atomized water vapor is sprayed on the inner wall of the concrete pipe, using the water vapor to wet the inner wall of the concrete, keeping the inner wall of the concrete clean and tidy, thus improving the detection effect. And when spraying the water vapor, it can also perform dust suppression on the dust, keeping the inside of the concrete pipe clean and tidy. At this time, the first gear drives the second toothed ring to rotate. The second toothed ring drives the rotating shaft to rotate. The rotating shaft drives the high-definition camera to rotate, and the inner wall after cleaning can be photographed comprehensively. Since the diameter of the second gear is larger than that of the first gear and the diameter of the second toothed ring is larger than that of the first toothed ring, the rotation speed of the second toothed ring is less than that of the first toothed ring. Due to the lower rotation speed, it can be clearer during the shooting process. And the shooting data will be transmitted to an external computer through the terminal controller I. The shooting data is analyzed by the computer to facilitate the discovery of cracks on the inner wall of the concrete pipe, thus improving the detection effect.

[0014] The present invention provides a concrete pipe damage detection device. It has the following beneficial effects:

[0015] 1. The present invention can clean the inner wall of a concrete pipe by rotating the cleaning plate. During the cleaning process, dust is generated. By starting the exhaust fan, the dust is sucked into the dust collection box. When absorbing the dust, the dust concentration sensor can detect the dust concentration, and the detected dust concentration data is transmitted to the terminal controller II. The terminal controller II controls the suction force of the exhaust fan. When the dust concentration is too high, the suction force of the exhaust fan will also be relatively large, preventing the concentration from being too high and the dust from not being processed in time, resulting in the dust covering the inner wall of the concrete pipe again, thus avoiding affecting the detection of cracks in the concrete pipe. After cleaning and dust suction, water in the water tank is pumped out by a water pump, and the water is sprayed through the left half of the connecting cylinder and the atomizing nozzle. The atomized water vapor is sprayed on the inner wall of the concrete pipe, and the inner wall of the concrete is wetted with the water vapor to keep the inner wall of the concrete clean and tidy, thereby improving the detection effect.

[0016] 2. By placing this detection device inside the concrete pipe, the electric push rod is started at this time to move the placement plate outward until the hub motor mechanism contacts the inner wall of the concrete pipe, and the hydraulic rod is started to push the slider to move to the right. One end of the connecting rod is driven by the slider to move to the right. Since the length of the connecting rod remains unchanged, the sliding rod is pushed to move outward, so that the cleaning plate contacts the inner wall of the concrete pipe. Therefore, concrete pipes of different sizes can be detected, improving the practicability of this device. BRIEF DESCRIPTION OF THE DRAWINGS
