[0016] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] As Figures 1 - 3 shown, the present utility model provides a precise positioning and hoisting device applicable to a large water depth environment, including a hoisting ship 1 and a dam body 11. The dam body 11 is located below the hoisting ship 1. A crane control room 4 is fixedly installed at the top of the hoisting ship 1. Hoisting arms 5 are fixedly installed on the left side and the front side of the crane control room 4. Two winches 7 are fixedly installed at the top of the hoisting ship 1, and the two winches 7 are respectively located on the left and right sides in front of the crane control room 4. Steel cables 8 are fixedly installed on the front sides of the two winches 7 and the front side of the bottom end of the hoisting arm 5, and the bottom end of the steel cable 8 is fixedly connected with a block 6. The block 6 is located above the dam body 11. An underwater visual monitoring system 9 is fixedly installed on the right side at the top of the hoisting ship 1. The underwater visual monitoring system 9 includes a high-definition camera and a real-time data analysis module, which can provide clear video images under low light conditions, and through image processing algorithms, automatically identify and track the position and state of the block. The front end of the underwater visual monitoring system 9 is fixedly connected with an L-shaped sonar connecting rod 12, and a sonar device 10 is fixedly installed at the bottom end of the L-shaped sonar connecting rod 12. The sonar device 10 adopts a multi-beam sounding instrument design. By emitting acoustic beams, it measures the depth of each point on the water bottom to generate a high-resolution underwater topographic map;

[0018] Before the hoisting operation, first obtain underwater terrain data through the multi-beam sounding instrument of the sonar device 10, which can scan the underwater environment in detail and generate an accurate three-dimensional topographic map. These data not only provide detailed measurement information of the base of the dam body 11, but also reveal any potential obstacles or unstable areas that may affect the hoisting operation. Through the analysis of these data, the operation team can formulate a detailed operation plan to ensure the smooth progress of the hoisting operation. And through the high-definition camera and real-time image transmission technology included in the underwater visual monitoring system 9, the operator can view the position and state of the underwater hoisting component in real time in the control center. Any slight abnormality can be discovered and processed in time, avoiding potential safety hazards. Then, the winches 7 and the hoisting arms 5 can be coordinated with the steel cables 8 and the block 6 to carry out the hoisting work.

[0019] As Figures 1 - 3As shown in the figure, a GPS positioning system 2 and an intelligent control module subsystem 3 are fixedly installed on the rightmost side of the top of the hoisting ship 1. The GPS positioning system 2 can update position data in real time in a dynamic environment and provide centimeter-level positioning accuracy. The intelligent control module subsystem 3 combines a high-precision gyroscope, an accelerometer, and an attitude sensor to detect the attitude and motion state of the device, and adopts an adaptive control algorithm to adjust the actions of the hoisting equipment according to real-time data. The GPS positioning system 2 is located behind the intelligent control module subsystem 3, and both the GPS positioning system 2 and the intelligent control module subsystem 3 are located on the right side of the underwater visual monitoring system 9;

[0020] Through the GPS positioning system 2, the position of the hoisting and lowering ship is monitored and adjusted in real time to ensure its accurate alignment with the predetermined hoisting point. The positioning system can not only provide the current position data, but also predict future position changes to help the operator make early adjustments and ensure the continuity and accuracy of the hoisting operation. Furthermore, through advanced algorithms and sensor data, the azimuth and angle of the hoisting equipment can be adjusted in real time. Whether in the start-up, operation, or stop phases, the intelligent system can automatically adjust the equipment according to the actual situation to ensure that the hoisting component remains stable during the lowering process.

[0021] Next, the working principle of the precise positioning hoisting device applicable to the deep water environment will be specifically described.

[0022] As Figures 1 - 3As shown, before the hoisting operation, first, underwater terrain data is obtained through the multibeam echosounder of the sonar device 10, which can scan the underwater environment in detail and generate an accurate three-dimensional topographic map. These data not only provide detailed measurement information on the base of the dam body 11 but also reveal any potential obstacles or unstable areas that may affect the hoisting operation. By analyzing these data, the operation team can formulate a detailed operation plan to ensure the smooth progress of the hoisting operation. Through the GPS positioning system 2, the position of the hoisting and lowering ship is monitored and adjusted in real time to ensure its precise alignment with the predetermined hoisting point. The positioning system can not only provide current position data but also predict future position changes to help the operator make early adjustments and ensure the continuity and accuracy of the hoisting operation. Furthermore, through advanced algorithms and sensor data, the orientation and angle of the hoisting equipment can be adjusted in real time. Whether in the starting, running, or stopping stages, the intelligent system can automatically adjust the equipment according to the actual situation to ensure that the hoisted component remains stable during the lowering process. Through the high-definition camera and real-time image transmission technology included in the underwater visual monitoring system 9, the operator can view the position and status of the underwater hoisted component in real time at the control center. Any slight abnormality can be detected and processed in a timely manner, avoiding potential safety hazards. Moreover, the core components of the system are connected through a high-speed data communication network to ensure real-time data transmission and collaborative work. The system integration center is responsible for coordinating the work of each module, uniformly scheduling and managing the hoisting operation, and ensuring the stability and safety of the hoisting operation.

[0023] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
