Description
Technical Field
The invention relates to the technical field of detection, in particular to a non-contact inspection method and detection equipment for bulk cargo in a ship.
Background
Bulk carriers, as the name implies, are vessels that carry bulk cargo. The bulk cargo is one of naked cargos, cannot be counted and packaged, and generally refers to bulk grains, ores, coal, petroleum and the like. Bulk carriers are designed to carry bulk cargo from the shape and structure of the hold to the strength of the hull. Bulk carriers are divided into dry bulk carriers and liquid bulk carriers
The dry bulk carrier has single cargo variety, does not need loading and transportation of packing, baling and boxing, is not afraid of extrusion, and is convenient to load and unload, so that the dry bulk carrier is a single deck carrier. The total load capacity is more than 50000 tons, and generally no cargo equipment is installed. Due to the large differences in the loading factors (volume per ton of cargo) for grain, coal, ore, etc., the required cargo hold volume varies in many ways, as well as the structure, arrangement and equipment of the ship's hull. Therefore, it is common practice to refer to only a ship having a similar cargo stowage factor such as grain and coal as a bulk carrier, and a ship having a cargo stowage factor such as ore sand with a small stowage factor as an ore sand carrier.
Before the bulk cargo ship enters a port for unloading, personnel are required to check the cargos by boarding the ship, but the general body of the bulk cargo ship is huge, so that the personnel are inconvenient to board the ship, and the personnel are required to board the ship as much as possible to reduce the contact on the premise of epidemic situation at present.
