Description

Technical Field

[0002] A barrage is a hydraulic engineering structure used to intercept the water flow in rivers, lakes or reservoirs. Its function is to raise the water level upstream and form a water storage area to meet various needs such as irrigation, water supply, power generation, flood control, and shipping. A barrage usually consists of a dam body, a spillway, a water conveyance culvert, etc. The dam body of a barrage is usually made of concrete structure.

[0003] Since the barrage needs to withstand the huge water pressure brought by the upstream water flow, it is necessary to frequently detect the dam body. Especially when cracks appear in the dam body, it is necessary to detect, evaluate and repair them. However, usually the dam body is relatively high. When cracks appear on the side of the dam body, it is difficult to reach the on-site position for detection. And for manual detection by suspension, there is a greater risk. Some existing flight measurement devices cannot get close to the target position. Existing flight devices are more likely to fall and cause damage to the equipment when reaching near inclined buildings or the ground. The operation difficulty is high, and continuous professional equipment detection cannot be carried out. Only long-distance shooting can be done, and the close-up equipment cannot be used normally.

Detailed Embodiment

[0020] The following further describes the present application in detail with reference to the drawings.

[0021] Please refer to Figures 1 to 3 , a river dam automatic detection device disclosed in the embodiment of the present application. Please refer to Figure 1 , which includes an accommodation box 1. The appearance of the accommodation box 1 is rectangular. Universal wheels 2 are installed at the corners near the bottom of the accommodation box 1. The universal wheels 2 are connected to a driving motor. A plurality of counter-pressure rotors 3 are installed outside the accommodation box 1. When the counter-pressure rotors 3 rotate, the pressure points to the bottom of the accommodation box 1. A crack gauge 4 is installed inside the accommodation box 1. Please refer to Figures 2 - 3 , the crack gauge 4 includes two groups of transducers 401, and each group includes two transducers 401. Please refer to Figure 1, two measuring windows 41 are provided at the bottom of the accommodation box 1, horizontally and vertically. Pressing frames 51 are slidably installed at positions in the accommodation box 1 opposite to the measuring windows 41. Two groups of transducers 401 are slidably installed on the two pressing frames 51 respectively. A pressing driving member 52 is fixedly installed in the accommodation box 1, and the output end of the pressing driving member 52 is fixedly connected to the pressing frame 51. Please refer to Figure 2 , at least one sliding driving member 53 is fixedly connected to each of the pressing frames 51, and the output end of the sliding driving member 53 is connected to the transducer 401. Please refer to Figure 1 , at least one macro camera 6 is installed at the bottom of the accommodation box 1, and a suspension ring 7 is installed on the outside of the accommodation box 1.

[0022] Specifically, through the counter-pressure rotor 3, the accommodation box 1 can move on the side wall of the dam through the omnidirectional wheels 2, and a certain pressure is maintained when the transducer 401 contacts the measurement surface. Two groups of transducers 401 are provided, one group is located on one side of the crack, and the other group is used for cross-crack measurement. By setting the pressing driving member 52 and the sliding driving member 53, the transducer 401 is driven to complete the measurement.

[0023] In this way, by installing the crack detector 4 in the accommodation box 1, the accommodation box 1 is positioned at the position to be detected through the macro camera 6, the counter-pressure rotor 3 and the omnidirectional wheels 2, and the transducer 401 is driven by the pressing driving member 52 and the sliding driving member 53 to complete the automatic measurement, which is convenient for detecting the cracks on the side wall of the dam and reduces the danger of manual detection.

[0024] In some feasible ways, the accommodation box 1 is in the shape of a rectangular box, which is convenient for installing components and storage. For easy movement, the omnidirectional wheels 2 are selected as Mecanum wheels, and the counter-pressure rotor 3 is a multi-rotor UAV rotor structure. The accommodation box 1 is pressed against the side wall of the dam by the thrust provided by the rotation of the rotor. The crack detector 4 is a prior art, including a control box and a transducer 401. When in use, two transducers 401 are required to perform same-side measurement and cross-crack measurement of the crack. Two groups of transducers 401 are provided, and the two groups of transducers 401 are respectively located at the measurement positions of one of the measurements by moving the accommodation box 1. For easy observation, multiple macro cameras 6 are provided.

The specific model can be directly installed using the existing overall packaging structure of this type to achieve the wireless communication function.

[0026] As a specific implementation manner of an automatic detection device for a river dam provided by the application, please refer to Figure 3, further including a coating assembly 8. The coating assembly 8 includes a driving rod 81 which is slidably mounted in the accommodating box 1. The driving rod 81 is connected with a coating driving member 82. One end of the driving rod 81 close to the transducer 401 is provided with a scraping box 83. A coating box 84 is mounted on the side of the driving rod 81 away from the transducer 401 and away from the scraping box 83. A coating pipe 85 is arranged at the center of the coating box 84. The other end of the coating pipe 85 is connected with an injection pipe 86. The injection pipe 86 is filled with a coupling agent. The injection pipe 86 is connected with an injection driving member 87. Wherein, one coating assembly 8 is correspondingly arranged for each transducer 401.

[0027] Generally speaking, when the transducer 401 is in use, in order to improve the measurement accuracy, it is necessary to coat the coupling agent on the surface. After a measurement is completed, the coupling agent needs to be replaced. To facilitate multi-point measurement, the coating assembly 8 is provided. After a measurement is completed, the transducer 401 is moved above the driving rod 81. The coating driving member 82 drives the driving rod 81 to slide, so that the scraping box 83 scrapes off the used coupling agent. Then, the coating box 84 is slid to below the transducer 401, and the coupling agent is extruded through the coating pipe 85 to achieve re-coating. During use, the transducer 401 can expand and contract to ensure the smooth progress during coating and scraping. The end of the transducer 401 and the upper ends of the scraping box 83 and the coating box 84 are made of soft materials to reduce damages such as breakage caused during the scraping process, and at the same time help to improve the thoroughness of scraping.

[0028] Further, the scraping box 83 is in the shape of a rectangular box with an open upper end. A scraping plate 831 is mounted on the side of the upper end of the scraping box 83 away from the transducer 401, and the scraping plate 831 covers half of the opening of the scraping box 83.

[0029] It should be understood that by setting the scraping plate 831, the upper end of the scraping box 83 is in a semi-open state, which is convenient for collecting the scraped coupling agent, and at the same time improves the thoroughness of scraping, reduces the possibility of dropping and affecting the operation of other equipment, improves environmental protection, and reduces the pollution caused by the measurement to the environment.

[0030] Further, the coating box 84 is in the shape of a round box with an open upper end and a diameter larger than the end of the transducer 401, and the coating pipe 85 is located at the center of the coating box 84.

[0031] It should be understood that by setting the coating box 84 with a diameter larger than that of the transducer 401, it is convenient to completely cover the end of the transducer 401 during the extrusion process of the coating pipe 85.

[0032] In some feasible ways, the driving rod 81 is slidably mounted on the track provided at the bottom of the accommodating box 1. After the transducer 401 is moved to a proper position, the upper surface of the scraping plate 831 is flush with the end face of the transducer 401, and the upper end face of the coating box 84 is flush with the end face of the transducer 401, so that there is a certain gap between the bottom of the coating box 84 and the end face of the transducer 401, which is convenient for forming an effective coupling agent coating layer. Among them, both the coating driving member 82 and the injection driving member 87 are electric push rods.

[0033] For the convenience of cleaning the scraping box 83 and replenishing the coupling agent of the injection tube 86, both the scraping box 83 and the injection tube 86 are selected with a detachable connection structure to improve the convenience during use. Specifically, a bolt connection form or a disassembly structure such as a snap connection can be selected.

[0034] As another specific implementation manner of a river dam automatic detection device provided by the application, please refer to Figure 2 , track rods 511 are fixedly installed at both ends of the pressure application frame 51 where the accommodating box 1 is located, and both ends of the pressure application frame 51 are slidably installed on the track rods 511 respectively.

[0035] Combined with the specific use scenario, by setting the track rods 511, it is convenient to limit the movement of the pressure application frame 51 and improve the movement accuracy of the pressure application frame 51.

[0036] In some feasible ways, the pressure application frame 51 is in the shape of a rectangular frame, and the track rods 511 are cylindrical rods.

[0037] As a specific implementation manner of a river dam automatic detection device provided by the application, the sliding driving member 53 includes a threaded rod 531, sliding blocks 532 and a stepping motor 533. The thread directions at both ends of the threaded rod 531 are opposite. The two sliding blocks 532 are slidably installed on the pressure application frame 51 and are respectively threadedly connected to both ends of the threaded rod 531. The sliding blocks 532 are respectively fixedly connected to a transducer 401, and the output end of the stepping motor 533 is connected to the threaded rod 531.

[0038] It should be understood that by setting the threaded rod 531, it is convenient to synchronously control the two transducers 401 and make the sliding distance of the transducers 401 more accurate.

[0039] In some feasible ways, a plurality of laser signal receiving modules are fixedly installed on the pressure application frame 51 corresponding to the detection positions, and a laser signal transmitting module is installed on the sliding block 532. The position of the transducer 401 is corrected by signal connection between the receiving module and the transmitting module.

[0040] In some feasible ways, a pressure sensor is arranged at the output end of the pressure application driving member 52. By setting the pressure sensor, it is convenient to better control the downward pressure of the transducer 401.

[0041] For the convenience of using an automatic detection device for a river channel dam body in this application, this application also discloses an operation method, including: S1. Determine the crack position by using a drone or other means; In some weather with good visibility, the position where the crack exists can be seen through the human eye or a telescope, etc. And in some cases, the patrol personnel are familiar with the position of each crack, which can improve the working speed. S2. Use a hoist to suspend the suspension ring 7 and lower the detection device at the crack position; The hoist can use existing lifting equipment such as drones, or common structures such as long-arm truck-mounted cranes and hanging brackets. Place this structure on the side of the river dam. S3. After lowering to the specified height, turn on the counter-pressure rotor 3 to make the universal wheel 2 fit the side wall of the dam body; When reaching the position, the counter-pressure rotor 3 works to generate a counter-thrust, so that the universal wheel 2 can stay tightly on the surface of the dam body without falling. By adjusting the rotation speed of the counter-pressure rotor 3, different thrusts can be generated, and further, it can also stay on a vertical surface. Cooperating with the provided universal wheel 2 can realize walking on the surface of the dam body. S4. Drive the universal wheel 2, observe through the macro camera 6, move the detection device to a suitable position above the crack, so that both transducers 401 in the first group are located on one side of the crack, and the two transducers 401 in the second group are located on both sides of the crack respectively; The setting of the universal wheel 2 can flexibly adjust the traveling direction, and thus adapt to cracks of different shapes. There are multiple macro cameras provided, which can collect more information around the gap. It should be noted that the transducers 401 located on the same side of the crack can also be used for measurement, rather than necessarily being located on both sides of the crack. In some existing devices, the transducers 401 use forms such as rays and ultrasonic waves, so they do not need to be located on both sides at the same time. In addition, for S5. Turn on the first group of transducers 401, drive the transducers 401 to fit the side wall of the dam body for detection through the pressure application driving member 52, and then retract the transducers 401. After driving the transducers 401 to slide to the specified position through the sliding driving member 53, drive the transducers 401 to fit the side wall of the dam body for detection again through the pressure application driving member 52, and cycle in turn; S6. Turn on the second group of transducers 401 and perform the same operation as in step S5; S7. Retract the detection device.

[0042] Furthermore, when performing multi-point detection, it also includes replacing the coupling agent through the coating assembly 8 after steps S5 and S6.

[0043] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
