Description

Technical Field

[0001] This utility model relates to the field of wind turbine gearbox technology, and in particular to a dust removal device for the inside of a wind turbine gearbox. Background Technology

[0002] The gearbox of a wind turbine is one of the key components of wind power generation equipment, used to transfer the kinetic energy of the rotating wind turbine to the generator to produce electricity. It is usually composed of multiple gears, which increase the wind turbine speed through precise transmission ratios and convert it into a speed suitable for generator operation. The inside of its housing contains lubricating oil, and due to thermal expansion and contraction, it cannot be sealed and must be open to the atmosphere. This makes it easy for dust to enter. The air filter is the medium for opening to the atmosphere. Its dehumidification and dust removal design ensures that the air entering the equipment is clean and dry, effectively protecting the quality of the lubricating oil and preventing dust from entering and accumulating inside the gearbox and causing pollution problems. Because there is lubricating oil inside the gearbox housing, air filters are mostly installed above the gearbox housing. However, the force exerted by the gear rotation on the lubricating oil will still throw some of the lubricating oil towards the connection between the air filter and the gearbox, causing contamination of the filter element and affecting the stable operation of the air filter. In addition, when installed above the gearbox, it is easily contaminated by dust, increasing its filtration volume per unit time, accelerating the replacement frequency, and increasing the workload. Utility Model Content

[0003] The purpose of this utility model is to provide a dust removal device inside a wind turbine gearbox, which avoids the problem of lubricating oil and its oil mist contaminating the filter element. It also allows for quick disassembly and assembly of the filter element while placing its ventilation port below the gearbox to avoid dust contamination. This avoids frequent filter element replacement, reduces workload, improves dust removal efficiency, and ensures the purity of the lubricating oil inside the gearbox.

[0004] To achieve the above objectives, a wind turbine gearbox internal cleaning device is provided, comprising: a gearbox body, wherein several support rods are symmetrically fixed at the bottom of the gearbox body, a base plate is fixedly connected to the bottom end of the support rods, a rectangular housing is fixedly connected to the top center of the base plate, a filter element is filled inside the rectangular housing, a sealing plate is snapped and fixed to the right side of the filter element, the sealing plate is correspondingly and sealingly snapped and connected to the rectangular housing, a straight passage chamber is fixedly connected to the top left side of the rectangular housing, a frame is fixedly connected to the top of the straight passage chamber, and an inclined guide channel frame is fixedly connected to the middle right side of the frame, the lower right end of the inclined guide channel frame corresponding to the gearbox body. The outer shell of the gearbox body is connected and fixed. The frame sleeve is filled with oil-absorbing cotton, and a sealing cap is glued to the top of the oil-absorbing cotton. The sealing cap is fitted into the frame sleeve. By setting an inclined guide groove frame to connect with the frame sleeve and assembling oil-absorbing cotton inside, the lubricating oil is isolated while the generated oil mist is absorbed, avoiding the problem of contamination of the filter element. At the same time, a straight passage compartment is set to connect with the rectangular housing and the filter element is assembled in the left and right directions inside. This facilitates quick installation and removal of the filter element, and the air vent is placed below the gearbox to avoid dust contamination. This avoids frequent filter element replacement, reduces workload, improves dust removal efficiency, and ensures the purity of the lubricating oil inside the gearbox.

[0005] According to the aforementioned internal dust removal device for a wind turbine gearbox, the bottom of the base plate has several symmetrically arranged mounting slots, each corresponding to a screw for secure fixing.

[0008] According to the aforementioned internal dust removal device for a wind turbine gearbox, a buffer pad is fixedly connected to the center of the right side of the straight-through compartment, and the right side of the buffer pad is correspondingly fitted and fixed to the gearbox body. An elastic buffer space is reserved to prevent the internal passage of the straight-through compartment from deforming and closing due to pressure, thus affecting the stability of the passage.

[0009] According to the aforementioned internal dust removal device for a wind turbine gearbox, symmetrical support plates are fixed to the top of the rectangular casing, and the top of the support plates is fixedly connected to the gearbox body. This provides auxiliary support for the gearbox and ensures a stable connection between the two.

[0010] According to the aforementioned internal dust removal device for a wind turbine gearbox, a baffle is fitted onto the left side of the straight-through compartment, and the upper and lower sides of the baffle are fixedly connected to the frame and the rectangular casing, respectively. This provides unilateral anti-collision protection for the straight-through compartment and the gearbox body.

[0011] According to the aforementioned internal dust removal device for wind turbine gearboxes, the inner surface of the inclined guide channel frame is covered with a layer of impermeable membrane to prevent oil seepage and contamination.
