Description

Technical Field

[0001] This invention relates to the field of wind power generation technology, and specifically to a remanufacturing apparatus and method for using a wind turbine. Background Technology

[0002] Wind power generation consists of wind turbine generator sets, towers supporting the generator sets, battery charging controllers, inverters, unloaders, grid connection controllers, and battery banks. Wind turbine generator sets include wind rotors, generators, towers, and nacelles (also known as wind turbine boxes, which include yaw braking structures).

[0003] Currently, the yaw braking structure of wind turbine generators generally includes a yaw bearing, a yaw brake disc (referred to as brake disc), and a hydraulic brake. The yaw brake disc is connected to the yaw bearing, and the hydraulic brake achieves braking through the friction between the hydraulic brake disc and the yaw brake disc. However, the yaw brake disc has the following problems in actual use:

[0004] First, the grease inside the yaw bearing and on the yaw bearing teeth can easily overflow onto the yaw brake disc. As it accumulates, the grease on the yaw brake disc becomes thicker and thicker, and the adhesion of dust will affect the rotation effect of the hydraulic brake.

[0005] Secondly, yaw brake discs are mostly made of metal. Excessive wear on the surface of a yaw brake disc can render it irreparable. Damaged yaw brake discs not only affect the normal operation of the wind turbine but also require replacement. Replacing with a new yaw brake disc is not only expensive and complicated, but the new yaw brake disc also requires a break-in period with the wind turbine, which significantly reduces the lifespan and operational stability of the wind turbine.

[0006] In view of this, the present invention is hereby proposed. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and to provide a remanufacturing apparatus and method for using wind turbine generators.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] On one hand, the present invention provides a remanufacturing apparatus for wind turbine generators, including a mounting base disposed inside the wind turbine housing, wherein an adjustment mechanism is provided at the top end of the mounting base and a fixing member for connecting to one side of the brake disc is provided at the bottom end; it also includes a movable plate, wherein the adjustment mechanism is slidably connected to the movable plate, a rotating mechanism is provided on one side of the movable plate, and a grinding disc connected to the rotating mechanism is provided on the opposite side.

[0010] It also includes a pretreatment mechanism for treating oil stains on the brake discs, the pretreatment mechanism being connected to the movable plate.

[0011] Furthermore, the adjustment mechanism includes a mounting frame, a first motor, and a threaded shaft. The mounting frame is fixed to the top of the mounting base, the first motor is fixedly connected inside the mounting frame, and the main shaft of the first motor is fixedly connected to one end of the threaded shaft. The other end of the threaded shaft is rotatably connected to the mounting frame, and a threaded sleeve that can move along its axial direction is fitted on the threaded shaft. A connecting block that is fixedly connected to the moving plate is provided on the outer wall of the threaded sleeve.

[0012] Furthermore, the pretreatment mechanism includes a side frame, a preheating plate, and a cleaning component. The side frame is connected to a movable plate, and the side frame has a first opening and a second opening. The preheating plate is located at the first opening, and the cleaning component is located inside the side frame and can extend or retract from the second opening. An oil collection frame is detachably connected to the bottom of the side frame.

[0013] Furthermore, the cleaning assembly includes a hydraulic transmission component, a movable frame, and a third motor. The hydraulic transmission component is fixedly connected inside the side frame, and its free end is connected to the movable frame. A pair of rotating shafts are rotatably connected to the movable frame along its height direction. The third motor is connected to the top of the movable frame, and its free end is fixedly connected to either of the rotating shafts. A pulley is fixedly connected to the outer periphery of each rotating shaft, and a wiping belt is sleeved on the two pulleys.

[0014] It also includes a support plate, which is sleeved on a pair of rotating shafts and located below the wiping belt.

[0015] Furthermore, a guide roller passing through the support plate is provided on the movable frame between the two rotating shafts, and the outer wall of the guide roller is in contact with the inner wall of the wiping belt;

[0016] It also includes a rejection plate, which is fixedly connected to the movable frame and is located at an angle to the outside of the wiping belt and in contact with the outer wall of the wiping belt.

[0017] Furthermore, the device also includes a linear drive mechanism, one end of which is detachably connected to a collection mechanism, and the other end is fixedly connected to a moving plate. The collection mechanism is located below the grinding disc and is used to collect grinding debris.

[0018] Furthermore, the collecting mechanism includes a debris collecting frame detachably connected to the linear drive mechanism, and a debris blocking component that can move up and down is provided inside the debris collecting frame on either side along its length.

[0019] Furthermore, the chip-blocking assembly includes a second motor fixed inside the chip collection frame, and the main shaft of the second motor is fixedly connected to a drive gear;

[0020] It also includes a baffle plate and several limiting posts. The baffle plate has a through groove, and the several limiting posts pass through the through groove and are fixedly connected to the inner wall of the debris collection frame. A rack that meshes with the drive gear is fixedly connected to the outer side of the baffle plate.

[0021] Furthermore, the device also includes a protective cover located on one side of the grinding disc and connected to the movable plate, the protective cover being fitted onto the transmission end of the rotating mechanism or the rear end of the grinding disc or the connection between the rotating mechanism and the grinding disc.

[0022] On the other hand, the present invention provides a method of using a remanufacturing apparatus for wind turbines, based on the remanufacturing apparatus for wind turbines as described above, comprising the following steps:

[0023] Step 1: Install the device on one side of the brake disc. When the brake disc needs to be polished, first adjust the pretreatment mechanism to a suitable position away from the brake disc using the adjustment mechanism. Then, turn on the preheating plate of the pretreatment mechanism to heat the oil stains on the surface of the brake disc. Finally, wipe the heated oil stains using the cleaning component of the pretreatment mechanism.

[0024] Step 2: After the oil stains on the brake disc are cleaned, the grinding disc is started to grind the brake disc by turning on the rotating mechanism. At the same time, the position of the collecting mechanism is adjusted by the linear drive mechanism of the device so that the debris can be collected.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1) The present invention proposes a remanufacturing device for wind turbine generators. The device is installed on a bracket on one side of the brake disc. By starting the adjustment mechanism, the moving plate is moved, thereby bringing the grinding disc into contact with the brake disc. Then, by starting the rotation mechanism, the brake disc is ground, thereby realizing the remanufacturing and repair of the brake disc and solving the problem that the brake disc cannot be repaired after excessive wear.

[0027] 2) The present invention proposes a remanufacturing device for wind turbines. This device is further equipped with a pretreatment mechanism. The preheating plate of the pretreatment mechanism can heat the oil stains on the surface of the brake disc to ensure its fluidity. This facilitates the wiping of the brake disc surface by the wiping belt after the hydraulic transmission component drives the moving frame to slide out, making subsequent grinding operations easier. In addition, the guide roller of the pretreatment mechanism contacts and supports the wiping belt. Through the cooperation of the rejection plate on one side of the wiping belt and the guide roller, the oil stains wiped on the surface of the wiping belt are removed and then fall into the oil collection frame for collection, ensuring that the wiping belt can be used continuously. This solves the problem that the rotation effect of the hydraulic brake is affected by excessive grease and dust on the brake disc.

[0028] 3) The present invention proposes a remanufacturing device for wind turbine generators. The device is further provided with a linear drive mechanism, which drives the collection mechanism to move so that the debris collection frame of the collection mechanism is located below the grinding disc. Then, by starting the second motor, the drive gear is driven to rotate. The drive gear drives the rack to move, thereby causing the baffle plate to extend from the debris collection frame to block the grinding debris from splashing, thus realizing the centralized collection and processing of debris.

[0048] Exemplary embodiments will now be described in detail. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples consistent with some aspects of the invention as detailed in the appended claims.

[0049] On the one hand, please refer to Figures 1-7 This embodiment provides a remanufacturing device for wind turbines, including a mounting base 1 disposed inside the wind turbine housing. Two sets of symmetrical adjustment mechanisms 2 are mounted on the top of the mounting base 1, and a fixing member 3 for connecting to one side of the brake disc is disposed at the bottom. It also includes a moving plate 4, the adjustment mechanisms 2 are slidably connected to the moving plate 4, a rotating mechanism 5 is disposed on one side of the moving plate 4, and a grinding disc 6 connected to the rotating mechanism 5 is disposed on the opposite side.

[0050] It also includes a pretreatment mechanism 7 for treating oil stains on the brake disc, the pretreatment mechanism 7 being connected to the movable plate 4 and located on the right side of the grinding disc 6.

[0051] In this embodiment, there are four fixing members 3, which are respectively installed at the four top corners near the mounting base 1. Each fixing member 3 is a rectangular block, the top of which is connected to the bottom of the mounting base 1 by bolts, and the bottom has a groove structure for connecting to the bracket on the brake disc side inside the fan box. The structure of the fixing member 3 and its connection method with the fan box are not limited, as long as it can achieve connection with the inside of the fan box.

[0052] In this embodiment, the rotating mechanism 5 includes a housing, in which a motor with forward and reverse rotation functions is installed. The motor passes through the moving plate 4 and is connected to the grinding disc 6. The grinding disc 6 is driven to rotate by the motor drive shaft. Of course, the housing can also contain other devices that can make the grinding disc 6 rotate, which is not limited here.

[0053] like Figure 2 As shown, the adjustment mechanism 2 includes a mounting frame 21, a first motor 22, and a threaded shaft 23. The mounting frame 21 is fixed to the top of the mounting base 1. The first motor 22 is fixedly connected inside the mounting frame 21, and the main shaft of the first motor 22 is fixedly connected to one end of the threaded shaft 23. The other end of the threaded shaft 23 is rotatably connected to the mounting frame 21. A threaded sleeve 24 that can move along its axial direction is sleeved on the threaded shaft 23. A connecting block 25 that is fixedly connected to the moving plate 4 is provided on the outer wall of the threaded sleeve 24.

[0054] Specifically, the first motor 22 drives the threaded shaft 23 to rotate, and the rotation of the threaded shaft 23 drives the outer threaded sleeve 24 to make linear motion, which in turn drives the connecting block 25 and the movable plate 4 connected to it to move, so as to adjust the position of the movable plate 4 so that the grinding disc 6 can contact the brake disc to carry out grinding and remanufacturing work.

[0055] Furthermore, the pretreatment mechanism 7 includes a side frame 71, a preheating plate 72, and a cleaning assembly 73. The side frame 71 is connected to the movable plate 4, and the side frame 71 has a first opening and a second opening. The preheating plate 72 is protruding and fixedly connected to the first opening. Figure 1 The cleaning component 73 is disposed inside the side frame 71 and can extend or retract from the second opening. The bottom of the side frame 71 is detachably connected to an oil collection frame 74.

[0056] In this embodiment, the bottom of the side frame 71 has an opening that communicates with the oil collection frame 74, allowing the oil stains to fall into the oil collection frame 74 when cleaning oil stains on the wiping strip 736. The preheating plate 72 is an electric heating plate, powered by mains electricity.

[0057] like Figure 3 and Figure 4 As shown, the cleaning assembly 73 includes a hydraulic transmission component 731, a movable frame 732, and a third motor 733. The hydraulic transmission component 731 is fixedly connected inside the side frame 71, and its free end is connected to the movable frame 732. A pair of rotating shafts 734 are rotatably connected to the movable frame 732 along its height direction. The third motor 733 is connected to the top of the movable frame 732, and its free end is fixedly connected to the rotating shaft 734 on the left side. A pulley 735 is fixedly connected to the outer periphery of each rotating shaft 734, and a wiping belt 736 is sleeved on the two pulleys 735.

[0058] It also includes a support plate 739, which is sleeved on a pair of rotating shafts 734 and located below the wiping belt 736, for fixing the wiping belt 736 to prevent it from slipping down.

[0059] Specifically, the hydraulic transmission component 731 can be a hydraulic rod, or it can be an electric telescopic rod, a cylinder, or a series of linear push mechanisms.

[0060] like Figure 4 and Figure 5 As shown, a guide roller 737 passing through the support plate 739 is provided on the movable frame 732 between the two rotating shafts 734, and the outer wall of the guide roller 737 is in contact with the inner wall of the wiping belt 736.

[0061] It also includes a rejection plate 738, which is fixedly connected to the movable frame 732. The rejection plate 738 is located at an angle to the outside of the wiping belt 736 (i.e., it is set at an angle on the movable frame 732) and contacts the outer wall of the wiping belt 736 to clean oil stains on the wiping belt 736.

[0062] In this embodiment, the preheating plate 72 can heat the oil stains on the surface of the brake disc to ensure its fluidity, making it easier for the wiping belt 736 to wipe the surface of the brake disc and ensure subsequent polishing work.

[0063] During the degreasing process, the wiping belt 736 is supported by the guide roller 737, and the oil stains on the surface of the wiping belt 736 are removed by the rejection plate 738 on one side of the wiping belt 736 in cooperation with the guide roller 737. The oil stains fall into the oil collection frame 74 for collection, ensuring that the wiping belt 736 can be used continuously.

[0064] Furthermore, the device also includes a linear drive mechanism 8, one end of which is detachably connected to a collection mechanism 9, and the other end is fixedly connected to a moving plate 4. The collection mechanism 9 is located below the grinding disc 6 and is used to collect grinding debris.

[0065] like Figure 6 As shown, the collecting mechanism 9 includes a debris collecting frame 91 that is detachably connected to the linear drive mechanism 8. Inside the debris collecting frame 91, on the left side along its length, is a debris blocking component 92 that can move up and down.

[0066] Specifically, the linear drive mechanism 8 can be a series of linear push mechanisms such as hydraulic rods, electric telescopic rods, and cylinders, and its function is to push the debris collection frame 91 to be located below the grinding disc.

[0067] like Figure 7 As shown, the chip blocking assembly 92 includes a second motor 921 fixed inside the chip collection frame 91, and a drive gear 922 is fixedly connected to the end of the main shaft of the second motor 921;

[0068] It also includes a baffle plate 923 and a pair of vertically distributed limiting posts 924. The baffle plate 923 has a through groove, and the pair of limiting posts 924 pass through the through groove and are fixedly connected to the inner wall of the debris collection frame 91 to provide support for the baffle plate 923. A rack 925 that meshes with the drive gear 922 is fixedly connected to the outer side of the baffle plate 923.

[0069] In this embodiment, both the rack 925 and the baffle plate 923 have an arc-shaped structure.

[0070] Specifically, during the grinding process, the linear drive mechanism 8 moves the collection mechanism 9, positioning the debris collection frame 91 below the grinding disc 6. Then, the second motor 921 is activated, driving the drive gear 922 to rotate. The drive gear 922 moves the rack 925, causing the baffle plate 923 to extend from the debris collection frame 91. The baffle plate 923 serves to prevent grinding debris from splashing, achieving centralized collection and processing of the debris.

[0071] Furthermore, the device also includes a protective cover 10 located on one side of the grinding disc 6 and connected to the movable plate 4. The protective cover 10 is sleeved on the transmission end of the rotating mechanism 5, the rear end of the grinding disc 6, or the connection between the rotating mechanism 5 and the grinding disc 6.

[0072] In this embodiment, as Figure 1 As shown, the protective cover 10 is fixedly connected to the movable plate 4 by bolts and is sleeved at the connection between the rotating mechanism 5 and the grinding disc 6. The present invention does not limit the specific structure of the protective cover 10, as long as it can provide protection.

[0073] On the other hand, this embodiment provides a method of using a remanufacturing apparatus for wind turbines, which includes the following steps based on the aforementioned remanufacturing apparatus for wind turbines:

[0074] Step 1: Install the device on one side of the brake disc. When the brake disc needs to be polished, first adjust the pretreatment mechanism 7 to a suitable position away from the brake disc through the adjustment mechanism 2, then turn on the preheating plate 72 of the pretreatment mechanism 7 to heat the oil stains on the surface of the brake disc, and finally wipe the heated oil stains through the cleaning component 73 of the pretreatment mechanism 7.

[0075] Step 2: After the oil stains on the brake disc are cleaned, the rotating mechanism 5 is turned on to make the grinding disc 6 start grinding the brake disc, so as to realize the remanufacturing and repair of the brake disc. At the same time, the position of the collecting mechanism 9 is adjusted by the linear drive mechanism 8 of the device so that the debris can be collected.

[0076] It should be noted that the installation of the device of the present invention does not affect the operation of the wind turbine generator set. The brake disc can be polished while the wind turbine generator set is working or after it has stopped working.

[0077] Furthermore, the term "fixed connection" or "connection" as used in this invention is a general term and may specifically include fixing methods such as welding, integral molding, and bonding.

[0078] This article uses specific examples to illustrate the principles and implementation methods of the present invention.
