Problems solved by technology

[0004] However, there are still relatively large defects in the prior art. For example, when the oil cylinder exerts thrust or pull on the wind turbine, it will also be subjected to the reaction force exerted by the wind turbine. The problem of damage due to excessive load, and during the detection process of wind turbines, the oil cylinder needs to work for a long time to provide different loads. If the time is too long, the internal temperature of the oil cylinder will rise. If the heat accumulated in the oil cylinder cannot be discharged in time, it will cause Oil cylinder burning problem

Embodiment 1

[0032] A wind turbine loading device, comprising a loading plate 1, a connecting flange 2 and a wind power main engine 3 connected in sequence from right to left, the right end of the loading plate 1 is provided with four hydraulic cylinders 4, and the output ends of the four hydraulic cylinders 4 and The right end face of the loading plate 1 is fixedly connected, and the output ends of the four hydraulic cylinders 4 pull the loading plate 1 left and right to simulate the axial force received by the wind power host 3. There are two hydraulic cylinders 4 above the loading plate 1, and the two hydraulic The output end of the oil cylinder 4 is fixedly connected to the upper end face of the loading plate 1 to simulate the longitudinal force and the bending moment caused by the gravity of the wind power main engine 3. Two hydraulic oil cylinders 4 are arranged on the rear side of the loading plate 1, and the two hydraulic oil cylinders 4 The output end is fixedly connected to the re...

Embodiment 2

[0038] The second embodiment optimizes the structure of the heat exchange cylinder 20 on the basis of the first embodiment, that is, the heat exchange cylinder 20 is extended along the direction close to the ventilation hose 19, and the rotating rod 21 is rotated to extend out of the heat exchange cylinder 20 and close to the ventilation hose. One end of 19, and the inner wall and outer wall of the heat exchange cylinder 20 are fixedly connected with a number of heat exchange fins 24, the heat exchange fins 24 are arranged to improve the heat exchange effect of the evaporating liquid and the flowing air, so that the flowing air passes through the heat exchange cylinder 20. At the same time, it can carry more cooling capacity, thereby improving the cooling effect of the hydraulic cylinder 4. An elastic collar 25 is fixedly connected to the inner wall of one end of the heat exchange cylinder 20 near the ventilation hose 19, and the rotating rod 21 slides through the elastic collar...

Embodiment 3

[0040] The third embodiment optimizes the connection structure of the overall device on the basis of the first embodiment, that is, the hydraulic cylinder 4 is integrally connected with a fixed block 28, and the fixed block 28 and the heat dissipation plate 5 are fixedly connected by tightening the bolts 29. , by adopting the connection method of tightening the bolts 29 to facilitate the connection or disassembly of the hydraulic cylinder 4 and the cooling plate 5, and the fixed block 28 is provided with an elastic gasket 30 that squeezes and fits with the end of the tightening bolt 29. The end of the tightening bolt 29 and the pressing surface of the fixing block 28 provide buffers to avoid the problem that the end of the tightening bolt 29 and the pressing surface of the fixing block 28 are damaged due to excessive pressing force. The upper reaction force plate 7 is fixedly connected, and the lower end of the reaction force plate 7 located on the rear side and the right side ...

Description

technical field [0001] The invention relates to the technical field of wind turbines, in particular to a loading device for wind turbines. Background technique [0002] With the continuous development of wind turbine technology, the research and development direction of wind turbines tends to be larger. pregnancy. The load that can be realized by the existing test platform is only the axial torque of the wind turbine to the transmission chain, and the single-degree-of-freedom load of the axial torque can only roughly verify the operation ability of the prototype, and cannot truly reflect the actual operation of the wind turbine transmission chain and control system. The working performance under the working conditions, the test data has a very limited effect on the correction of the wind turbine simulation model, and it is difficult to meet the expectation of improving the simulation calculation performance. [0003] In the prior art, a loading system with a publication nu...
