[0036] The equipment installation platform 1 is made of galvanized I-beam, and may also be made of galvanized butt-jointed channel steel or a galvanized square steel pipe with partial openings on four sides and axial reinforcement.

[0037] The top plate of the equipment installation platform 1 has a reserved installation hole 10, through which the bottom plates 11 of multiple devices can be installed, and the bottom plates 11 are connected to the base 12 of the wind farm measurement equipment. The bottom plate 11 of the test equipment is connected to the equipment installation platform 1 by four stainless steel bolts, and the height of the stainless steel bolts is adjusted to level the bottom plate of the equipment to ensure the flatness of the installation of the measurement equipment. The bottom plate 11 is rigidly connected to the base of the wind farm measurement equipment by stainless steel bolts.

[0038] The bottom plate of the equipment installation platform 1 has reserved installation holes 10. The installation holes 10 on the upper flange plate of the installation platform 1 are used for installing and fixing the equipment. The installation holes 10 on the lower flange plate are used for cable binding and fixing and also take rainwater drainage into consideration. The measured equipment cables are routed through the bottom plate of the platform, and the cables can be bound and fixed through the installation holes 10.

[0039] The vertical bracket 2 and the oblique bracket 3 are made of galvanized stainless steel round steel pipe components, and the bottom horizontal bracket 4 is made of galvanized stainless steel square steel pipe components. The vertical bracket 2, the oblique bracket 3, and the bottom horizontal bracket 4 can also be made of other galvanized stainless steel components such as I-beams and channel steels. The design of the double vertical bracket ensures the overall rigidity of the sliding rod type wind farm measurement equipment installation bracket and improves the wind vibration resistance of the equipment installation bracket.
