A cage model test platform

Abstract

A net cage model test platform is characterized in that two main beams of the platform span across the track and are moved by being pulled by a trailer. The main beams of the platform are connected by longitudinal connecting rods and horizontal connecting rods to form a platform frame, and the middle of the platform frame is a connecting support. It is used to install the volume measuring instrument, the four corners and the front of the platform frame are installed with splints, used to install the camera rod and the tow rod, and the side camera operation rod is installed on one side of the platform frame. The camera is waterproof and comes with LED lighting. Fixed at the bottom of the camera operating rod, the tension sensor bracket is installed on the top of the draw bar to place the pull sensor, and the pulley is installed at the bottom of the draw bar as a transmission device for the tension cable of the model test. The camera devices at the four corners and sides of the platform transmit the multi-angle model images to On the display side, the tension data is measured by the tension sensor and transmitted to the computer display side, and the data is read and saved in real time. The entire platform structure is connected to the rear of the trailer through the front-end connection device.

Description

technical field [0001] The invention relates to net cage model test equipment. Background technique [0002] Cage culture, especially seawater cage culture, has become an important part of my country's aquaculture industry. As a culture carrier, the structure and performance of the cage are directly related to industrial benefits. The structure of the cage mainly includes a buoyancy frame and a net. In the shape of a garment, it is usually equipped with a sinker. The net cage will be deformed by the action of the water flow in the water. The mooring system for fixing the net cage needs to be designed through experiments and calculations. These are difficult to do in the actual environment. The main way is to study and improve the structural performance of the net cage through the tank model test one. The net cage model tank test is to make the culture net cage into a model net cage in the tank according to the similar theory and conduct the test in the tank to study the hyd...

Problems solved by technology

[0003] In the prior art, similar net cage model tests are generally carried out in the dynamic water tank and the static water tank. Due to the size limitation of the dynamic water tank, the large size ratio of the model cage is increased, which increases the error of the test results and the accuracy of the data. Reliability is difficult to guarantee

Although the size of the stilling tank is relatively large, the current test is still carried out on the basis of the original trawling model test platform, and only the simulation test of the double-point mooring system can be carried out. The accuracy and collection methods of the data are relatively backward. In addition, the cage model The image acquisition and volume measurement of the test cannot be completed in the current test equipment, and it is difficult to meet the test requirements of the cage model test. Therefore, designing and manufacturing a new test platform suitable for the cage model test and developing a set of data acquisition methods have become Current technical issues to be resolved
