With the technical development of the wind power generation field, the environmental range in which the existing wind power generator set can be applied is expanded from land to sea, and the marine environment is an important environmental place for the wind power generator set to operate. For offshore wind turbines, corrosion can be generated on components of the turbines due to environmental factors such as sea wind and sea water, in order to ensure the structural strength of each component, the corrosion grade of the turbines in the service environment is obtained, materials and coatings are selected according to the grade, so that moderate corrosion resistance treatment is carried out on the turbines, and the problems of component damage caused by insufficient corrosion resistance and the possibility of high cost caused by corrosion resistance transition can be reduced.

Further, where the corrosion grade at a particular location is obtained, it is often necessary to install a plurality of corrosion-resistant coated corrosion hangers at that location, expose the test hangers to the natural environment of that location for about one year, and then determine the corrosion grade of the offshore wind service environment and the corrosion and aging resistance of the coating by measuring the corrosion rate of the corrosion hangers. Because the wind turbine generator system is large in size, a plurality of groups of test hanging plates are usually required to be installed at different positions, and a plurality of hanging plates are usually arranged in each group of test hanging plates, so that test errors are reduced in a mode of taking average values of corrosion test results measured by the plurality of hanging plates.

On the basis, the applicant finds that the existing bracket for supporting the test hanging plate is generally made of metal materials, is mainly applied to land environments or can provide a platform with a large and flat installation site, has large volume and heavy weight, is inconvenient to assemble, disassemble and transport, and is difficult to meet the test requirements of the offshore wind turbine generator.

Further, the connection wire 21 is used for suspending the test board 200, and the connection wire 21 itself needs to have a certain strength on the basis of a certain weight of the test board 200, so that the connection wire 21 may be composed of a combination of a core 211 having a higher strength and an outer cladding insulation layer 212 providing an insulation effect. Alternatively, the core 211 may be made of a wire rope, for example, stainless steel; the insulating layer 212 may be made of a wear-resistant and corrosion-resistant plastic or resin material.

The number of the fixing catches 11 through which the fixing cables 12 for simultaneously fixing the same row of test boards 200 pass may be the same adjacent, and the positions of the fixing catches 11 in the second direction Y may correspond to each other to form the uniformly arranged mounting positions.

In some alternative embodiments, the connection assembly 20 further includes a plurality of clamps 22, each of the plurality of clamps 22 being disposed at an end of the connection wire 21 adjacent to one side of the fixing cable 12 and being respectively located at opposite sides of the fixing cable 12 in the first direction X.

The connection assembly 20 in the embodiment of the present application is used for connecting the test board 200 to be tested to the fixing assembly 10, specifically, the connection wire 21 is passed through the connection hole 30 on the test board 200 and bypasses the fixing cable 12, and two ends of the connection wire 21 are connected and fixed, so that the test board 200 can be suspended on the fixing cable 12.

Meanwhile, in addition to the clamps 22 provided at the connection points of the two ends of the connecting wire 21, a clamp 22 may be provided on the side of the fixing cable 12 close to the test board 200, so that both clamps 22 are provided close to or abutting against the fixing cable 12, and the fixing cable 12 is clamped therebetween. Alternatively, the clamp 22 may be made of an aluminum alloy that is lightweight, non-corrosive, and easy to machine.

Specifically, the clamps 22 respectively located at both sides of the fixing cable 12 can make both side ends of the connecting wire 21 respectively wound around and connected and fixed by both sides of the fixing cable 12, so that the joint position of the connecting wire 21 is fixed at a position where the joint position is not in contact with the test board 200, and on the basis of improving the connection stability, the connecting wire 21 can be prevented from moving in the self extending direction, and adverse effects on the test board 200 are avoided.
