Technical Field

[0001] The utility model belongs to the technical field of hanging baskets, and particularly relates to a folding hanging basket for the operation and maintenance of wind turbines. Background Art

[0002] A wind turbine is a power device that converts wind energy into mechanical work. The mechanical work drives the rotor to rotate, and finally outputs alternating current. A wind turbine generally consists of components such as a wind wheel, a generator, a yaw device, a tower, a speed limit safety mechanism, and an energy storage device. After the wind turbine is installed and used, it needs to be repaired after a fault occurs in the generator, and also needs to be regularly maintained during daily use. Since the wind wheel and the power generation device of the generator are all at the top of the tower, workers need to go to the top of the wind turbine for maintenance work, and a folding hanging basket for the operation and maintenance of wind turbines is required.

[0003] It is known that the Chinese publicly authorized utility model: (Publication No.: CN218323820U) discloses a folding hanging basket for the operation and maintenance of wind turbines, including a bottom plate. Both ends of the two sides of the bottom plate are fixedly connected with first support rods. A plurality of cross rods are fixedly connected between the two first support rods on both sides of the bottom plate and between the two first support rods at one end of the bottom plate. Two slide rails are hinged on one side of the bottom plate. A slide bar matching with the slide rail is slidably connected in the slide rail. A clamping plate is fixedly connected to the outer wall of the slide bar. A semi-circular groove is opened on one side of the clamping plate. An extension rod is slidably connected in the cross rods on both sides of the bottom plate.

[0004] However, it is found that the above device has the following problems in the implementation of related technologies: In the prior art during use, it is difficult to adjust the distance between two adjacent cross rods, and it is difficult to avoid the falling of two parts of the wind turbine, which has a certain safety hazard. A folding hanging basket for the operation and maintenance of wind turbines is proposed. Summary of the Utility Model

[0012] Preferably, the fixing mechanism includes two symmetrically distributed fixing plates, a protective pad is fixedly connected to the bottom of the fixing plate, and the protective pad is made of rubber. The setting of the fixing plate can cooperate with the protective pad to squeeze and fix the top of the items for the operation and maintenance of the wind turbine, and can prevent the items for the operation and maintenance of the wind turbine from shaking above the placement plate.

[0014] The working principle and beneficial effects of the present utility model are as follows:
