Embodiment 1

[0063] Such as Figure 1-9 As shown, a kind of model test device that the bottom type culture platform provided by the present embodiment resists the impact of the ocean current in the horizontal direction includes:

[0064] A pair of linear tracks 1, which are distributed in parallel on both sides of the still water tank 2, each linear track 1 extends longitudinally along the still water tank 2, and is fixed to the guide rail support seat 3;

[0065] A first installation platform 4 includes a pair of first angle steels 5 distributed in parallel in the longitudinal direction of the still water tank 2 and all spanning the still water tank 2, and a roller is provided on both ends of each first angle steel 5 Support 6, on the shaft part of each roller bracket 6, a roller 7 is installed to cooperate with its corresponding linear track 1, as Figure 4 As shown, since the linear track 1 in this embodiment adopts an I-shaped steel structure, and its contact surface with the roller 7...

Embodiment 2

[0088] A kind of model testing device for the anti-horizontal direction ocean current impact of a kind of bottom type breeding platform provided by the present embodiment, its general structure is consistent with embodiment 1, but as Figure 10 As shown, in this embodiment, the upper end of the extended high side 21 of the second installation platform 20 is provided with three installation holes 41, and the three installation holes 41 on the same extended high side 21 are distributed in a straight line and at intervals.

[0089] In the above-mentioned second installation platform 20, the installation holes 41 on different heights are selected to be fixed with the first installation platform 4, and the distance from the bottom surface of the second installation platform 20 to the water surface of the still water tank 2 can be adjusted, so that the model testing device provided by the present invention It can be applied to the test of the bottom-sitting farming platform model 39 ...

Embodiment 3

[0091] A kind of model testing device for the anti-horizontal ocean current impact provided by the bottom-sitting culture platform provided in this embodiment, its general structure is consistent with embodiment 2, but as Figure 11 As shown in the present embodiment, the model test device for the bottom-mounted farming platform to resist the impact of horizontal ocean currents also includes a cylinder 42, which is installed on the second installation platform 20 and extends outward during the non-test process. The long cylinder rod 43 comes into contact with the tank 34 earlier than the pressure sensor 38 .

[0092] The cylinder 42 installed on the second installation platform 20 above has an outwardly extending cylinder rod 43 that can prevent the tank body 34 from contacting the pressure sensor 38 during non-testing.

[0093] Therefore, a kind of model testing device provided in the present embodiment is used to test the performance of the bottom-sitting aquaculture platfor...

Abstract

The present invention discloses a model testing device for resisting ocean current impact in horizontal direction of a bottom-supported type breeding platform. The device is characterized in that: ina structure of the device, four optical axis slider assemblies are arranged all parallel to a linear guide rail in a uniform matrix; a test mounting plate is supported together by four sliders, and the test mounting plate is provided with threaded through holes; a main waterway is provided with a branch that is sealed and docked with each threaded through hole; inside a trough body is provided with seabed sediments, and each suction nozzle is installed on the corresponding threaded through hole and extends into the seabed sediments; a water pressure sensor is connected in series on the main waterway and is slightly higher than the trough body in a vertical direction of space; during a test, the test mounting plate and / or the trough body are in contact with a pressure sensor; and a data acquisition device is in individual electrical connection with the water pressure sensor and the pressure sensor. The device solves the technical problem of "testing of resistance performance of sea-water impact in horizontal direction of the bottom-supported type breeding platform model in a static water tank", and has the advantages of a simple structure, convenient test operation and the like.

Description

technical field [0001] The invention relates to a model hydrodynamic testing device of a bottom-sitting farming platform, in particular to a model testing device for a bottom-sitting farming platform against the impact of ocean currents in a horizontal direction. Background technique [0002] As inshore farming tends to be saturated, it has become a trend to develop large-scale farming offshore. [0003] The bottom-sitting farming platforms used for offshore farming all use a rigid platform body. When the suction anchor is installed, first place its opening downwards and vertically on the mud surface, and it can penetrate into the mud surface under the action of its own weight or ballast. , when the anchor barrel enters the mud surface and reaches the sealing condition, the pump valve system is used to continuously discharge the accumulated water in the barrel, so that the pressure inside the barrel is continuously reduced, and the outside of the barrel is affected by water ...
