Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation, in particular to an external protective cover of an engine group for wind power generation. Background Art

[0002] During the wind power generation process, the wind power is effectively converted into electricity through the linkage control of the connected generator sets, and the power generation intensity is adjusted in conjunction with the assembled fan blades. The generator set is effectively protected by the external protective cover set. During use, it is inconvenient to effectively dissipate heat for the generator set.

[0003] In order to overcome the above defects, the prior art (application number CN202410714283.X, Chinese patent application date 2024-06-04) provides a heat-insulating wind turbine nacelle, which is closed by welding the nacelle shell and the rear cover plate, and then the heat-insulating interface plate is installed at the junction of the nacelle shell and the generator output end. After the generator main engine is installed in the nacelle shell, the generator and the heat-insulating interface plate are closed, effectively isolating the temperature transfer inside and outside the nacelle. The EPS insulation board, glass wool board and lightweight pad are arranged on the inner wall of the nacelle shell to provide a heat-insulating environment for the inside of the nacelle. A support bracket docking frame is provided at the bottom of the nacelle shell. The corresponding frame is installed according to the installation needs, which is convenient for the installation of the generator components and the efficient use of the internal space environment of the cabin cover. The control component arranged in the cabin cover keeps the internal closed and heat-insulated when the cabin cover environment temperature of the wind turbine is low, maintains the constant temperature environment required for the internal components to work, and controls the internal heat dissipation area as the temperature changes; there is also prior art (application number CN202223345219.4, Chinese patent application application date 2022-12-13) a metal nacelle cover of a wind turbine, which cooperates with the wind turbine through a first positioning hole, a first positioning ring, a second positioning hole and a second positioning ring The installation equipment is positioned on the mounting plate, thereby achieving the effect of avoiding installation deviation; through the cooperation of the fixing plate, the fixing rod, the support rod, the support plate and the fixing frame, the effect of fixed support and overall weight reduction is achieved; and the prior art (application number CN202323652345.9, Chinese patent application application date 2023-12-30) A dust-proof heat dissipation nacelle cover for wind power generation, which adds condensate to the inside of the condensate tank through a liquid filling pipe. Under the conduction action of the heat-conducting column, the heat sink can be kept in a low-temperature state. The heat generated by the operation of equipment such as the wind turbine increases the temperature inside the nacelle cover shell. According to the theorem of heat conduction, the heat will be transferred from the nacelle cover shell along the heat-conducting column. The higher temperature inside the nacelle cover shell is transferred to the lower temperature heat sink, and the wind in the high altitude quickly dissipates the heat through the ventilation hood. Rapid heat dissipation can be achieved without opening holes in the surface of the nacelle cover shell, and dust cannot enter the nacelle cover shell, effectively protecting wind turbines and other equipment, forming a dust-proof and heat-dissipating nacelle cover for wind power generation, avoiding the cleaning and maintenance problems caused by dust entering the nacelle cover, and bringing convenience to the use of the nacelle cover; although the existing technology can complete the heat dissipation, during operation, the protective cover set is not convenient to use for heat dissipation along with wind power generation, and it is not convenient to use wind power and the nacelle to cooperate with heat dissipation, which affects the working effect of the engine.

At the same time, the steel wire rope 22, the return spring 27 and the limiter assembly 26 form a through-structure; please refer to Figure 8 , the rotating shaft 29 rotates on the inner surface of the support frame 5, and the rotating shaft 29 is provided with a limited locking mechanism; the limiting locking mechanism includes a slot 30 opened on the inner surface of the rotating shaft 29, and the inner surface of the slot 30 is engaged with the limiting member 25, and a fan 31 is installed on the outer surface end of the rotating shaft 29, and a cooling pipe 32 is nested and connected to the inner surface of the support frame 5, and the cooling pipe 32 is located between the limiting assembly 26 and the fan 31, and a cooler 33 is installed on the outer surface end of the cooling pipe 32, and the cooler 33 is nested on the right side of the inner surface of the cabin 1; please refer to Figure 8 and Figure 9 The rotating shaft 29 and the support frame 5 form a rotating structure, and the rotating shaft 29 forms a limiting engaging structure with the limiting member 25 through the card slot 30, and the rotating shaft 29 and the fan 31 form an integrated structure, while the support frame 5 and the refrigeration pipe 32 form a nested structure.

When the telescopic block 24 is elastically engaged, the control wire rope 22 is connected to the movable frame 14, and the wire rope 22 is controlled to be nested and rotated on the positioning roller 23, thereby improving the use effect of the limit member 25. When the windward cover 3 is closed, the movable frame 14 will drive the telescopic block 24 and the limit member 25 installed by the wire rope 22 to disengage from the slot 30, thereby controlling the start-up of the cooler 33 and delivering the coolant to the cooling pipe 32 nested in the support frame 5, so that the internal circulation cooling process can be performed when the fan 31 in the cabin 1 rotates.
