Description
Technical Field
[0001] This utility model relates to the field of oil purifier technology, specifically to an oil purifier for wind turbine gearboxes. Background Technology
[0002] The gearbox is a key component of wind turbine generators. Its main function is to transfer the kinetic energy of the rotating wind turbine to the generator, thereby producing electricity. The gearbox typically consists of multiple gears that, through precise transmission ratios, increase the wind turbine's rotational speed and convert it into a speed suitable for the generator's operation. Since the wind turbine's rotational speed is usually very low, far below the speed required for the generator to produce electricity, the gearbox's speed-increasing function is crucial.
[0003] A gearbox oil purifier is a device specifically designed to treat gearbox lubricating oil. Its main function is to remove impurities, moisture, and oxidation products from the oil to restore or maintain its performance and extend its service life. When using an oil purifier for gearbox oil maintenance, maintenance personnel need to connect the purifier to the wind turbine generator set. Existing oil purifiers simply wrap the oil delivery pipe around a hook, which easily leads to tangling and knotting when the pipe is removed. Therefore, a wind turbine generator set gearbox oil purifier is proposed to solve the above problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a wind turbine gearbox oil purifier, which has advantages such as preventing pipe tangling and entanglement, and solves the problem of easy tangling and entanglement when removing pipes.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a wind turbine generator gearbox oil purifier, including a trolley frame, an oil purifier body mounted on the top of the trolley frame, a connecting pipe connected to the oil purifier body, and a coil assembly mounted on the top of the trolley frame and on the front of the oil purifier body.
[0006] The coil assembly includes a movable plate located above the trolley frame. An opening is formed inside the movable plate, and a winding rod is movably connected inside the opening. The bottom end of the winding rod is fixedly connected to the surface of the trolley frame. Support plates are provided on both the left and right sides of the trolley frame, and suspension ropes are fixedly connected to both sides of the movable plate. A counterweight is fixedly installed at the end of each suspension rope furthest from the movable plate. A slot is formed on the opposite side of each support plate, and a slider is movably connected inside each slot. A baffle is fixedly connected to the surface of each slider. The counterweight is located above the baffle. A pull plate is fixedly connected to the front of each baffle, and a magnet is fixedly installed on the inner side of the pull plate.
[0007] Furthermore, the trolley frame consists of a base plate, casters, and a support frame. The base plate is fixed to the oil purifier body. There are four casters, which are fixedly connected to the bottom of the base plate. The support frame is fixedly installed to the side of the base plate. The support frame is inclined, and the handrail of the support frame is covered with a rubber pad.
[0008] Furthermore, the number of the winding rods is four, arranged in groups of two, located on the left and right sides of the movable plate respectively.
[0009] The beneficial effect of adopting the above technical solution is that placing the connecting tube between two winding rods in a group can effectively prevent the connecting tube from loosening.
[0010] Furthermore, a slot is provided at the top of the support plate, and the support plate is perpendicular to the trolley frame.
[0011] The beneficial effect of adopting the above technical solution is that the hoisting rope is routed through the groove to the outside of the support plate, and the groove serves to limit the movement of the hoisting rope.
[0012] Furthermore, a placement plate is fixedly installed on the surface of the movable plate, and a placement opening is provided on the top of the placement plate.
[0013] The beneficial effect of adopting the above technical solution is that the interface connected to the connecting pipe can be placed in the placement plate, thereby limiting the interface.
[0014] Furthermore, the baffle is perpendicular to the pull plate, and a rubber pad is provided on the surface of the baffle.
[0015] The beneficial effect of adopting the above technical solution is that when the equipment moves, the counterweight shakes, and the friction between the counterweight and the rubber pad can be increased.
[0016] Furthermore, the distance between the counterweight and the ground is greater than the distance between the movable plate and the top of the winding rod, and a limit plate is provided at the top of the winding rod.
[0017] The beneficial effect of adopting the above technical solution is that when the counterweight falls freely downward due to gravity, it can drive the movable plate to be lifted upward until it is in contact with the limiting plate.
[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0019] This wind turbine gearbox oil purifier works by pulling a pull plate, which moves a baffle until the baffle separates from the counterweight. The counterweight falls due to gravity, causing the movable plate to move upward until the limiting plate of the winding rod limits the movable plate. At this point, because the connecting pipes are stacked on top of the movable plate, the connecting pipes will be freed from the limiting plate of the winding rod, making it easier for maintenance personnel to use the connecting pipes. Because the connecting pipes are stacked in an orderly manner and the vertical movement of the movable plate frees the connecting pipes from the restriction of the winding rod, there will be no knotting or tangling when dragging the connecting pipes.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figures 1 to 5 The wind turbine gearbox oil purifier in this embodiment includes a trolley frame 1, an oil purifier body 2 mounted on the top of the trolley frame 1, a connecting pipe 3 connected to the oil purifier body 2, and a coil assembly 4 mounted on the top of the trolley frame 1 and on the front of the oil purifier body 2.
[0028] The trolley frame 1 consists of a base plate, casters, and a support frame. The base plate is fixed to the oil purifier body 2. There are four casters, which are fixedly connected to the bottom of the base plate. The support frame is fixedly installed on the side of the base plate. The support frame is inclined and the handle of the support frame is covered with a rubber pad.
[0029] The omnidirectional wheels on the trolley frame 1 allow for flexible movement of the equipment outdoors. The coil assembly 4 effectively prevents the connecting pipe 3 from getting tangled or twisted during storage and use, greatly improving work efficiency. The connecting pipe 3 is connected to the wind turbine unit, and the gearbox oil can be filtered through the oil purifier body 2.
[0030] The coil assembly 4 includes a movable plate 401, located above the trolley frame 1. An opening 402 is formed inside the movable plate 401, and a winding rod 403 is movably connected inside the opening 402. The bottom end of the winding rod 403 is fixedly connected to the surface of the trolley frame 1. There are four winding rods 403, arranged in pairs on the left and right sides of the movable plate 401, so that the connecting pipe 3 is located between the pairs of winding rods 403, effectively preventing the connecting pipe 3 from loosening. Support plates 404 are provided on both the left and right sides of the trolley frame 1, with slots on the top of the support plates 404. The support plates 404 are perpendicular to the trolley frame 1, allowing the hanging rope 405 to pass through the slots and wrap around to the outside of the support plates 404. The slots limit the movement of the hanging rope 405. Hanging ropes 405 are fixedly connected to both the left and right sides of the movable plate 401, with the two hanging ropes 405 positioned away from the movable plate 401. A counterweight 406 is fixedly installed at one end. The distance between the counterweight 406 and the ground is greater than the distance between the movable plate 401 and the top of the winding rod 403. A limit plate is provided at the top of the winding rod 403 to ensure that when the counterweight 406 falls freely downward due to gravity, it can drive the movable plate 401 to be lifted upward until it is in contact with the limit plate. A slot 407 is opened on the side of the two support plates 404 that are separated from each other. A slider 408 is movably connected inside the two slots 407. A baffle 409 is fixedly connected to the surface of the two sliders 408. The counterweight 406 is located above the baffle 409. A pull plate 410 is fixedly connected to the front of the two baffles 409. The baffles 409 are perpendicular to the pull plate 410, and a rubber pad is provided on the surface of the baffles 409. When the equipment moves, the counterweight 406 shakes. The friction with the counterweight 406 can be increased by the rubber pad. A magnet 411 is fixedly installed on the inner side of the pull plate 410.
[0031] A placement plate 5 is fixedly installed on the surface of the movable plate 401. The top of the placement plate 5 has a placement opening, and the interface connected to the connecting pipe 3 can be placed in the placement plate 5, thereby limiting the interface.
[0032] By pulling the pull plate 410, the baffle 409 is moved until the baffle 409 separates from the counterweight 406. The counterweight 406 falls due to gravity, which in turn moves the movable plate 401 upward until the limiting plate of the winding rod 403 limits the movable plate 401. At this time, since the connecting pipe 3 is stacked on top of the movable plate 401, the connecting pipe 3 will be freed from the limit of the winding rod 403, making it convenient for maintenance personnel to use the connecting pipe 3. Because the connecting pipe 3 is stacked in an orderly manner, and after the vertical movement of the movable plate 401, the connecting pipe 3 is freed from the restriction of the winding rod 403, and no knotting or tangling will occur when dragging the connecting pipe 3.
[0033] The working principle of the above embodiments is as follows:
[0034] The omnidirectional wheels on the trolley frame 1 allow for flexible movement of the equipment outdoors, meeting the environmental requirements for wind turbine operation. During use, pulling the pull plate 410 moves the baffle 409 until it separates from the counterweight 406. The counterweight 406 falls due to gravity, which in turn moves the movable plate 401 upward. At this point, since the connecting pipe 3 is stacked on top of the movable plate 401, the connecting pipe 3 is released from the limit of the winding rod 403, making it easier for maintenance personnel to use the connecting pipe 3. Because the connecting pipe 3 is stacked in an orderly manner, and the vertical movement of the movable plate 401 ensures that the connecting pipe 3 is released from the restriction of the winding rod 403, there will be no knotting or tangling when dragging the connecting pipe 3.
[0035] During storage, the movable plate 401 is pressed down. As the movable plate 401 moves downward, the counterweight 406 moves upward until the movable plate 401 is in contact with the trolley frame 1. Then, the pull plate 410 is slid towards the trolley frame 1 until the baffle 409 is below the counterweight 406, thus releasing the movable plate 401. The connecting tube 3 is then placed between each set of winding rods 403, and winding is performed between the two sets, thus completing the storage. This prevents the equipment from scattering during movement and facilitates future use. It serves both storage and ease of use.
