[0002] The reservoir basin of pumped storage power stations mostly adopts reinforced concrete or asphalt concrete for anti-seepage. With the increase of service life, under the combined effects of water level changes, dry-wet cycles, temperature cycles, etc., the concrete panels have different degrees of aging damage, cracks, erosion, leakage and other defects and diseases, which have a significant impact on the structural safety, anti-seepage safety and durability of the panels, and affect the safe operation of the power station.

[0021] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0022] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0024] Reference Figure 1-5 A multi-eye imaging device capable of adaptive rotation and synchronous focusing comprises a beam mounting sleeve 1 and an imaging camera 3. The surface of the beam mounting sleeve 1 is evenly and linearly arrayed with mounting screw grooves 2. The front of the mounting screw groove 2 is provided with an imaging camera 3. The back of the mounting screw groove 2 is threadedly connected with a connecting support plate 4. The connecting support plate 4 is engaged with the surface of the imaging camera 3. The back of the connecting support plate 4 is connected with a control cable 5. Both ends of the beam mounting sleeve 1 are movably engaged with a rotating sleeve 6. A rotating motor 7 is provided inside the rotating sleeve 6, and the output shaft of the rotating motor 7 is connected to the end of the beam mounting sleeve 1. The surface of the crossbeam mounting sleeve 1 is connected to multiple groups of imaging cameras 3 through the mounting screw groove 2 for underwater detection and imaging, so that the entire device can be installed on the surface of the underwater detection trolley. The installed horizontal mounting sleeve is controlled to deflect at an angle through the operation of the rotating motor 7, thereby driving the imaging camera 3 to rotate and adjust the detection angle, thereby increasing the detection range and realizing multi-eye imaging. The control software can be used to automatically adjust the angle of the rotating mechanism, and the computer can be used for synchronous focusing, thereby ensuring clear imaging on the water surface and underwater concrete surfaces, and ensuring the quality of surface defect detection of concrete panels.

[0025] In order to increase the stable connection and signal data transmission between the imaging camera 3 and the connecting support plate 4, a connecting contact 8 is provided at the end of the imaging camera 3, and a contact groove 9 is provided on the surface of the connecting support plate 4. The connecting contact 8 and the contact groove 9 are electrically connected. The connecting contact 8 and the contact groove 9 are both annular, and the connecting contact 8 and the contact groove 9 are clearance-matched. When the entire imaging camera 3 and the connecting support plate 4 are connected, the imaging camera 3 is firstly spirally inserted into the mounting screw groove 2 along the front side of the crossbeam mounting sleeve 1, and the end surface of the imaging camera 3 is clearance-matched with the internal mounting screw groove 2, and the imaging camera 3 is connected to 3 / 4 of the length of the mounting screw groove 2, and then the connecting support plate 4 is inserted into the mounting screw groove 2 along the back thread of the crossbeam mounting sleeve 1. As it is slowly rotated and inserted, the connecting contact 8 on the surface of the connecting support plate 4 abuts against the contact groove 9 on the back of the imaging camera 3, and the contact groove 9 abuts against the connecting contact 8 until the connecting support plate 4 is completely installed. At this time, the connecting support plate 4 is connected to the back 1 / 4 position of the mounting screw groove 2, and the connecting contact 8 is completely abutted against the contact screw groove to complete the installation. Finally, the control cable 5 is connected along the back of the connecting support plate 4 to complete the connection of the entire device.

[0026] The other structures of the entire device are as follows: the size of the end of the connecting support plate 4 is the same as that of the end of the imaging camera 3, and the adjacent imaging cameras 3 are electrically connected to facilitate the connection and control of multiple imaging cameras 3. The two ends of the beam mounting sleeve 1 are engaged with the protrusions at the end of the rotating sleeve 6 through grooves, and the connecting positions of the beam mounting sleeve 1 and the rotating sleeve 6 are sealed. The imaging camera 3 and the connecting support plate 4 are sealed at the connecting edges with the mounting screw groove 2, which is convenient for underwater operations and prevents water seepage in the device. Specific embodiment 2:

[0028] Reference Figure 1-5 When the whole device is in use, it is connected to the external control software through the control cable 5, and the access line is connected to the rotating motor 7, which is used to synchronously rotate the connected beam pair and control the imaging parameters of the camera, etc., to ensure that the stability of the panel has no blind spots, high resolution, and high-quality imaging under different inclination angles and imaging environment conditions. Specific embodiment three:

[0030] Reference Figure 1-5 In actual use, the imaging camera 3 uses an existing industrial camera lens, and the mounting screw groove 2 can be replaced with an existing commonly used camera interface, such as a C-mount, a CS-mount, etc. The two interfaces are 1-inch-32UN British threaded connection ports. The threaded connection of the C-type interface and the CS-type interface is the same, the difference is that the back focus of the C-type interface is 17.5mm, and the back focus of the CS-type interface is 12.5mm. Because the back focus of the CS-type interface is 5mm shorter than that of the C-mount, the industrial camera with the CS-type interface can be connected and used with the C-mount and CS-mount lenses, but a 5mm adapter ring is required when using the C-mount lens. However, it is obvious that the industrial camera with the C-mount cannot use the CS-mount lens.

[0031] In summary:

[0032] The surface of the crossbeam mounting sleeve 1 is connected to multiple groups of imaging cameras 3 through the mounting screw grooves 2 for underwater detection and imaging, so that the entire device can be installed on the surface of the underwater detection vehicle. Through the operation of the rotating motor 7, the installed horizontal mounting sleeve is controlled to deflect at an angle, thereby driving the imaging camera 3 to rotate and adjust the detection angle, thereby increasing the detection range and realizing multi-eye imaging. The control software can be used to automatically adjust the angle of the rotating mechanism, and the computer can be used for synchronous focusing, thereby ensuring clear imaging on the water surface and underwater concrete surfaces, and ensuring the quality of surface defect detection of concrete panels.
