[0002] In water conservancy projects, the inspection of gate slot embedded parts is a key link in operation and maintenance, but the existing technology has obvious limitations: traditional inspection relies on manual diving or a single sensor, which has poor real-time performance, requires post-processing of data, and makes it difficult to detect problems in a timely manner; the equipment is large in size and has a fixed structure, making it difficult to adapt to different specifications of grab beams and prone to blind spots in inspection; it lacks the ability to mark the depth of defects, cannot quantify dimensional parameters, and cannot meet the needs of refined evaluation; some online inspections rely on continuous power supply and fiber optic connections, making it difficult to operate independently in complex environments. Commonly used acoustic detection also has its shortcomings. Sonar images have low resolution, can only identify obvious defects, and are difficult to capture subtle features. Furthermore, they are affected by acoustic reverberation in complex environments at close range, which reduces their accuracy. Summary of the Invention The technical problem to be solved by this utility model is that the acoustic detection devices currently used have insufficient ability to identify embedded parts in gate slots and have low accuracy.

[0003] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a gate slot embedded part identification device, including a target identification control cabin, a winding winch and an analysis system. The winding winch is wound with an optical fiber cable and connected to the target identification control cabin through the optical fiber cable. The target identification control cabin is equipped with an underwater lighting device and an optical identification device.

[0006] Preferably, the movable end of the mounting bracket includes a fixed section and an adjustable section that are hinged to each other. The fixed section is connected to the end wall of the target identification and control cabin, and the hinge between the fixed section and the adjustable section is bolted.

[0007] Preferably, lifting lugs are fixedly installed on the outer wall of the target identification and control cabin.

[0008] Preferably, the target identification control cabin integrates a depth sensor, an image processing module, a data storage module, and a lithium battery module; the depth sensor is used to detect the water depth where the target identification control cabin is located, and the optical identification device is signal-connected to the image processing module.

[0009] Preferably, the target identification and control cabin also has a built-in network switch, which includes an interface, a main control board and a power module, and the power module is electrically connected to the lithium battery module.

[0010] Preferably, the image processing module and the depth sensor are connected via internal wiring, and the target recognition control cabin is equipped with a partitioned mounting base for fixing the installation positions of both, so that the depth information and the associated annotation of the image frame can be synchronously transmitted through hardware connection.

[0014] 1. By setting up an optical recognition device in conjunction with an underwater lighting device to replace the traditional acoustic detection method, the texture and subtle features of the embedded surface can be clearly obtained, effectively identifying minute defects.

The winding winch 3 is wound with an optical fiber cable 2 and connected to the target identification control cabin 1 through the optical fiber cable 2. The target identification control cabin 1 is equipped with an underwater lighting device 8 and an optical identification device 7. The target identification control cabin 1 is connected to the analysis system 6 through the optical fiber cable 2.

[0021] The identification device implements two modes: offline detection mode and online detection mode.

[0022] In offline detection mode, there is no need to install the winch 3, eliminating the need for fiber optic cable 2 connection. The target identification control cabin 1, underwater lighting device 8, and optical identification device 7 are directly fixed to the fixed installation interface of the grab beam. After being connected in place via the surface cable, the machine is turned on. The target identification control cabin 1 acquires the collected images through the underwater lighting device 8 and optical identification device 7, and uses the internal image processing module to collect, compress, and store the image information, and performs image frame preprocessing, including adding time and water depth information tags to the images. After the operation is completed, the data is extracted and processed.

[0023] like Figure 3 As shown, in the online detection mode, after the electrical connection is completed, the target identification control cabin 1 is connected through the gantry crane, which drives the target identification control cabin 1 to move underwater. The winding winch 3 is used to synchronously wind up and wind down the fiber optic cable 2. The winding up and wind down control is based on the image information obtained by the analysis system 6. After the depth and position change, the winding up and wind down control is synchronously performed to maintain a stable supply of fiber optic cable 2. The winch 3 is equipped with a relay unit. After receiving the image data sent by the target identification and control cabin 1, it transmits the image data to the analysis system 6 remotely.

[0027] like Figure 1 As shown, the mounting bracket is triangular in shape, with the optical recognition device 7 mounted on the central rod of the mounting bracket, and underwater lighting devices 8 mounted on the rods along the edges of the mounting bracket. By mounting underwater lighting devices 8 on both sides of the optical recognition device 7, the two underwater lighting devices 8 provide sufficient range and intensity of light to the optical recognition device 7, enabling the optical recognition device 7 to acquire clear images.

[0028] like Figure 1 As shown. The movable end of the mounting bracket includes a fixed section and an adjustable section that are hinged to each other. The fixed section is connected to the end wall of the target identification and control cabin 1, and the hinge between the fixed section and the adjustable section is bolted.

[0029] The fixed section and the adjusting section are connected by a hinge, as shown in the attached figure. Figure 2 As shown, two ear plate connecting structures are installed on the movable end of the fixed section. Bolts are threaded between the two ear plates. By rotating the bolts, the distance between the two ear plates can be adjusted, thereby allowing the adjusting section to be loosened or clamped.

[0030] like Figure 1 As shown, lifting lugs are fixedly installed on the outer wall of the target identification and control cabin 1. These lugs are used to connect to a gantry crane, which then moves the target identification and control cabin 1.

[0031] As a preferred embodiment of this utility model, the target identification control cabin 1 integrates a depth sensor, an image processing module, a data storage module, and a lithium battery module; the depth sensor is used to detect the water depth where the target identification control cabin 1 is located, and the optical identification device 7 is signal-connected to the image processing module.

[0032] The image processing module uses a high-performance, low-power image processing development board. Its main functions are to preprocess images, compress and store video signals, and add depth and time information tags.

[0033] The main function of the data storage module is to store data in offline working mode.

[0034] The depth sensor is used to collect depth information from the detection device and mainly consists of an interface, a main control board, a pressure sensor, and a power module.

[0035] The target identification and control cabin 1 also integrates an optical transceiver, whose main function is to transmit communication and control signals during operation to the control system via optical fiber.

[0036] The target identification and control cabin 1 also has a built-in network switch, which includes an interface, a main control board and a power module. The power module is electrically connected to the lithium battery module.

[0037] The main function of lithium batteries is to provide power for the main optical lighting devices, optical recognition devices, and target recognition control cabin.

[0038] A network switch mainly consists of interfaces, a main control board, and a power module, and primarily provides network data transmission and switching for various terminal devices.

[0039] In a preferred embodiment of this utility model, the image processing module and the depth sensor are connected via internal wiring. The target recognition control cabin 1 is equipped with a partitioned mounting base for fixing the installation positions of both, enabling synchronous transmission of depth information and image frame association annotations through hardware connection.

[0041] The drive unit 4 uses a variable frequency motor, and the output end of the variable frequency motor is connected to the rotating shaft of the winding winch 3 through a belt drive structure. The drive unit 4 drives the winding winch 3 to rotate.

[0042] As a preferred embodiment of this utility model, the lithium battery module is an independent, sealed structure, embedded in a pre-reserved mounting slot on the side wall of the target identification and control cabin 1. The data storage module is connected to the lithium battery module via a waterproof interface, forming a hardware connection unit for offline operation. In offline operation mode, the target identification and control cabin 1 is powered by the lithium battery, enabling it to operate independently for 8 hours without cable connection.
