Abstract

The invention discloses a netting hydrodynamic test device, which comprises a flat plate, wherein a plurality of spaced measuring devices are mounted on the top surface of the flat plate, a main frame is mounted on the bottom surface of the flat plate, the main frame structurally comprises a quadrilateral structure defined by two transverse rods and two vertical rods, the transverse rod located at the top is fixed to the bottom surface of the flat plate, a transverse supporting rod is installed between the two vertical rods, and an inclined supporting rod is installed at one end of the transverse supporting rod and the joint of the transverse rod and the vertical rod; and a plurality of supporting rods are sequentially installed on the vertical rod at intervals from top to bottom, a clamping ring is arranged at one end of each supporting rod and connected to the vertical rod through a fixing pin, a screw hole is formed in the other end of each supporting rod, a corresponding penetrating through hole is formed in the pipe wall of each screw hole, and a fixing cable penetrates through each penetrating through hole and is locked through a clamping pin. The netting is connected to a fixing cable, so that the device can be prevented from interfering incoming flow and incoming waves, and the test precision is improved; and meanwhile, the netting can be conveniently replaced in the test, and the test efficiency is improved.

Description

technical field

[0001] The invention relates to the technical field of hydrodynamic testing, in particular to a netting hydrodynamic testing device and testing method. Background technique

[0002] Net clothing is a key component of fish farming equipment, and its hydrodynamic properties are related to the safe use of net clothing and the success or failure of fish farming. Fish farming equipment needs to face the action of waves and currents, so it is necessary to conduct experimental research on the hydrodynamic characteristics of nets under waves and currents.

[0003] When carrying out the hydrodynamic test of nets, a frame structure is currently used to fix the nets at a specific position in the tank or pool, and then test the hydrodynamic load and deformation state of the nets. The device has a certain interference effect on waves and currents, which has a certain impact on the test results, and it is time-consuming to replace the net clothing. Therefore, in order to...
