AI Technical Summary
In the existing technology, the method for measuring the ground clearance of wear-resistant blocks fails to effectively take into account factors such as fluid resistance, equipment wear and seabed topography changes in the dredging vessel's operating area, resulting in poor calculation accuracy.
The force exerted by the high-pressure nozzle on the wear-resistant block is calculated based on the fluid density, nozzle flow rate, and injection speed in the dredging area. The tensile and compressive force of the rake head on the wear-resistant block is obtained by combining the tensile and compressive force sensors. The weight of the wear-resistant block, the buoyancy of the fluid, and these forces are then input into a pre-trained ground clearance calculation model to obtain a more accurate ground clearance.
It improves the accuracy of calculating the ground clearance of wear-resistant blocks, enabling dredgers to adjust the rake head posture in real time during intelligent operations, thereby improving operational efficiency and quality.
