Problems solved by technology

At present, the model devices used at home and abroad are mainly square-frame netting devices, which are simple and easy to install, but more netting parameters and environmental variables are considered, such as the angle between netting and flow, multi-netting systems, waves, etc. flow conditions, etc., these netting devices cannot meet these test conditions

Abstract

The invention discloses a rotatable netting device for researching hydrodynamic force. The rotatable netting device comprises a supporting frame, a rotating device, a telescopic rod, a sliding device, a six-component sensor, a connecting rod, a netting frame and a netting. In the process of researching the hydrodynamic force of the planar netting under the pure flow effect, the netting is fixedly designed through the netting frame to reach a tensioning state, the netting is matched and fixed with the netting frame by adjusting the length of the telescopic rod, the incident flow angle of the netting is adjusted through the rotating device, and the netting frame is subjected to two-dimensional movement by moving the sliding device and adjusting the length of the telescopic rod. The netting test device can meet various netting assembly conditions and test working conditions due to the characteristics of detachability, modularization and multiple functions. According to the invention, adjustable parameters of a single netting test device are increased, and the netting test efficiency is improved.

Description

technical field [0001] The invention relates to the field of ships and marine engineering, in particular to a rotatable netting device for studying hydrodynamics. Background technique [0002] The cage aquaculture industry has developed rapidly with the growth of the population, but due to the limitation of offshore resources and more and more serious environmental pollution, it will become an inevitable trend to transfer the cages to the deep sea. Facing the harsh environment of the deep sea, understanding the hydrodynamic properties of the netting structure under the current condition has become a current research hotspot. [0003] In the study of the hydrodynamic properties of the net, the model test is a very key research method. Under normal circumstances, the research on the hydrodynamics of the net is generally divided into the measurement of the flow field and the force, that is, the change of the flow field before and after the water flow through the net and the ch...
