Abstract

The real-time measuring device and measuring method for the draft of a navigable ship according to the present invention are composed of a detection door, an automatic lifting control device for the detection door and a data acquisition and processing device; the detection door is a mounting frame, and the detection door is composed of The automatic lifting control device controls it to reach a predetermined depth position below the water surface, and is placed below the water surface that the navigable ship will pass through. An array of ultrasonic ranging sensors is installed on it, and the front of the ultrasonic ranging sensor is upward; The distance sensor array measures the vertical distance from the bottom surface of the entire ship to the detection door mounting frame, and all the measurement data constitute a data set C; then according to the installation depth H of the ultrasonic ranging sensor array on the detection door mounting frame, the water depth at the bottom of the ship will be obtained The data set D, where D=H-C; then find the maximum value in the data set D, which is the draft Dmax of the navigable ship, that is, Dmax=MAX(D).

Description

technical field [0001] The real-time measuring device and measuring method for the draft of a navigable ship according to the present invention relate to the measurement technology, in particular to the detection technology of overdraft of a ship lock or a navigable ship in a channel. Background technique [0002] At present, with the continuous increase of inland waterway shipping volume, the number and density of shipping ships have increased significantly, and various ship accidents have become increasingly serious threats to shipping safety, and their impact is also growing. Among them, the most serious and urgent problem is the overdraft of navigable ships. In order to ensure the safety of water traffic in inland rivers, the state needs to invest hundreds of millions of dollars every year and deploy thousands of waterway workers to dredge mud, clear obstacles and blast to ensure the smooth flow of waterways. However, driven by interests, some ship owners disregarded th...
