In addition, the terms "first", "second", etc. used in the present disclosure are to distinguish one element from another element and do not have order and importance. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0024] like Figure 1 and Figure 2 As shown, the present disclosure provides a guide structure of a radiator of a gearbox of a wind turbine, comprising: a guide bag 1, a first flexible fixing component 4 and a second flexible fixing component 5, wherein the guide bag 1 comprises a first opening and a second opening arranged opposite to each other, the first flexible fixing component 4 is arranged at the first opening and seals and fixes the guide bag 1 to a nacelle cover opening 2, the second flexible fixing component 5 is arranged at the second opening and seals and fixes the guide bag 1 to a radiator opening 3, the first flexible fixing component 4 comprises a first flexible belt 41 and a first tensioner 42, the first flexible belt 41 is arranged around the outer periphery of the first opening of the guide bag 1 and is tightened by the first tensioner 42 to fix and seal the guide bag 1 to the nacelle cover opening 2, the second flexible fixing component 5 comprises a second flexible belt 51 and a second tensioner 52, the second flexible belt 51 is arranged around the outer periphery of the second opening of the guide bag 1 and is tightened by the second tensioner 52 to fix and seal the guide bag 1 to the radiator opening 3.

[0025] Through the above technical solution, the cabin cover 2 and the radiator port 3 are connected through the diversion bag 1, and the first flexible belt ring 41 in the first flexible fixing component 4 provided at the first opening of the diversion bag 1 is provided at the outer periphery of the first opening of the diversion bag 1, and the first flexible belt 41 is tightened by the first tensioner 42, so that the first opening of the diversion bag 1 can be fixed and sealed to the cabin cover 2, and the second flexible belt 51 in the second flexible fixing component 5 provided at the second opening of the diversion bag 1 is set around the outer periphery of the second opening of the diversion bag 1, and the second flexible belt 51 is tightened by the second tensioner 52 The flexible belt 51 is locked, so that the second opening of the guide bag 1 can be fixed and sealed to the radiator port, so that the gear box radiator and the nacelle cover can be connected by the first flexible fixing component 4 and the second flexible fixing component 5 instead of the original metal steel bar set on the guide cloth. The first flexible belt 41 and the second flexible belt 51 are elastic and have sufficient tensioning force, so that the guide bag and the nacelle cover port 2 and the radiator port 3 can be reliably fixed and not affected by the vibration of the wind turbine generator set during operation, avoiding the occurrence of high oil temperature power limit and fault shutdown of the gear box caused by the fall of the guide cloth and poor heat dissipation.

[0026] It can be understood that in order to facilitate the first flexible belt 41 and the second flexible belt 51 to reliably fix the diversion bag to the cabin cover 2 and the radiator port 3, a first groove cooperating with the first flexible belt 41 and a sealing gasket arranged in the first groove are provided on the cabin cover 2, and the first flexible belt 41 is arranged around the outer periphery of the first groove. By tightening the first flexible belt 41 by the first tensioner 42, the first flexible belt 41 can make the diversion bag abut against the sealing gasket in the first groove. At this time, the first tensioner 42 is locked, so that the diversion bag 1 and the cabin cover 2 are fixed and sealed. Similarly, a second groove cooperating with the second flexible belt 51 and a sealing gasket arranged in the second groove are provided on the radiator port 3. The second flexible belt 51 is arranged around the outer periphery of the second groove. By tightening the second flexible belt 51 by the second tensioner 52, the second flexible belt 51 can make the diversion bag 1 abut against the sealing gasket in the second groove. At this time, the second tensioner 52 is locked, so that the diversion bag 1 and the radiator port 3 are fixed and sealed.

[0027] In some feasible embodiments, the first flexible belt 41 and the second flexible belt 51 can be nylon straps, and the first tensioner 42 and the second tensioner 52 can be ratchet tensioners. The first end of the nylon strap is fixedly connected to the first belt shaft of the ratchet tensioner, and the second end of the nylon strap passes through the belt groove of the ratchet shaft. By continuously pulling the pull rod, the baffle continuously pushes the ratchet to rotate, and the nylon strap is wound around the ratchet shaft, thereby tightening the nylon strap. The above-mentioned ratchet tensioner is an existing product, and the present disclosure will no longer describe the structure of the ratchet tensioner in detail.

[0028] In order to further improve the stability of the connection between the diversion bag 1 and the cabin cover 2 and the radiator port 3, respectively, in some practicable ways, the number of the first flexible fixing component 4 and the second flexible fixing component 5 are both multiple, and the multiple first flexible fixing components 4 and the multiple second flexible fixing components 5 are arranged at intervals along the length direction of the diversion bag 1. For example, the number of the first flexible fixing components 4 is two, the number of the second flexible fixing components 5 is two, and the two first flexible fixing components 4 are arranged at intervals along the length direction of the diversion bag 1. Two first positioning grooves used in conjunction with the first flexible fixing components 4 are arranged at intervals on the outer side wall of the cabin cover 2, so that the diversion bag 1 is fixed and sealed to the cabin cover 2 after the two first flexible belts 41 arranged in the length direction of the diversion bag 1 are respectively tightened and locked by the corresponding first tensioners 42, and two second positioning grooves used in conjunction with the second flexible fixing components 5 are arranged at intervals on the outer side wall of the radiator port 3, so that the diversion bag 1 is fixed and sealed to the radiator port 3 after the two second flexible belts 51 are arranged in the length direction of the diversion bag 1 are respectively tightened and locked by the corresponding second tensioners 52.
