Description

Technical Field

[0001] This application relates to the field of wind turbine yaw system technology, and in particular to a carbon dust collection device for the brake disc of a wind turbine yaw system. Background Technology

[0002] The yaw system of a wind turbine generator is designed to quickly and smoothly align with the wind direction when the wind speed vector changes, maximizing the wind energy received by the rotor. The yaw system locks the nacelle position by clamping the brake disc with a brake caliper. The brake disc is typically made of ductile iron, while the brake pads within the caliper are primarily made of graphite. During braking, the friction between the brake pads and the brake disc causes the graphite material on the brake pad surface to flake off, generating carbon dust. If this dust is not cleaned promptly, it can lead to dust pollution.

[0003] In passive yaw brake calipers, the brake pads are in continuous contact with the yaw system brake pads under the action of springs. To prevent the brake pads from drying out, grease is added to the brake pads. Also, because the yaw system brake face is downward, the carbon dust generated by the yaw system brake is difficult to collect. Utility Model Content

[0004] The technical problem to be solved by this application is that the brake pads of the existing passive yaw brake calipers are in continuous contact with the yaw system brake pads under the action of the spring. In order to prevent the brake pads from drying out, grease is added to the brake pads. Furthermore, since the brake surface of the yaw system faces downward, carbon powder is continuously generated by the yaw system brake and is difficult to collect.

[0005] To address the aforementioned problems, this application provides a carbon dust collection device for the brake disc of a wind turbine generator yaw system, comprising:

[0006] A ring-shaped dust collection tray is positioned around the brake caliper.

[0007] An oil receiving tray is disposed below the brake caliper and above the dust receiving tray, the oil receiving tray being located between two adjacent brake calipers.

[0008] In this application, a ring-shaped dust collection tray is arranged around the brake caliper below, fully covering the area where carbon dust splashes during braking. The dust collection tray receives and collects carbon dust that falls from the brake caliper during friction with the yaw system brake pads, preventing carbon dust from scattering onto other components of the unit or the environment, thus keeping the unit clean. An oil collection tray collects grease dripping from the brake pads, preventing grease from directly contaminating the carbon dust in the dust collection tray, and also facilitating grease collection. This carbon dust collection device not only effectively solves the problem of difficult collection of continuously generated carbon dust from the yaw system brake pads, but also addresses the collection of brake pad grease, improving the overall operating efficiency and maintenance convenience of the wind turbine generator set.

[0009] In order to install the dust collection disc below the yaw system, according to the above-mentioned wind turbine yaw system brake disc carbon dust collection device of this application, the disc wall of the dust collection disc extends downward to the bottom of the disc surface and is connected to a mounting disc parallel to the dust collection disc, and the mounting disc is connected to the yaw system through a mounting plate.

[0010] To facilitate the rinsing of the lubricating grease collected in the oil receiving pan, the carbon powder collection device for the yaw system brake disc of the wind turbine generator set described above in this application has a screen plate with several through holes placed on the surface of the oil receiving pan.

[0011] In order to facilitate the collection and processing of carbon powder collected on the dust collection plate, the carbon powder collection device of the yaw system brake disc of the wind turbine generator set according to the above application further includes: a dust suction device disposed above the dust collection plate.

A dust extraction hole is provided on one side of the vacuum block to penetrate the inside and outside of the vacuum chamber. The dust extraction hole is connected to a vacuum pump through a pipe.

[0014] In order to improve the collection efficiency of attached carbon powder, the carbon powder collection device for the yaw system brake disc of the wind turbine generator set according to the above application is provided with a brush on at least one side wall of the dust collection block.

[0015] Optionally, in the above-described wind turbine yaw system brake disc carbon dust collection device according to this application, the dust collection block is provided with a brush facing the dust collection disc surface.

[0016] Optionally, in the above-described wind turbine yaw system brake disc carbon dust collection device according to this application, the dust collection block is provided with a brush facing the inner wall of the yaw system below the brake disc.

[0018] Preferably, in the above-described wind turbine yaw system brake disc carbon dust collection device according to this application, the dust collection block is installed between two adjacent brake calipers via a dust collection block bracket.

[0019] The technical advantages of this application are as follows:

[0020] In this application, a ring-shaped dust collection tray is arranged around the brake caliper below, fully covering the area where carbon dust splashes during braking. The dust collection tray receives and collects carbon dust that falls from the brake caliper during friction with the yaw system brake pads, preventing carbon dust from scattering onto other components of the unit or the environment, thus keeping the unit clean. An oil collection tray collects grease dripping from the brake pads, preventing grease from directly contaminating the carbon dust in the dust collection tray, and also facilitating grease collection.

[0034] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0035] This application provides a carbon dust collection device for the brake disc of the yaw system of a wind turbine generator set, which aims to solve the technical problems of the difficulty in collecting carbon dust generated by the brake pads of the existing passive yaw brake calipers due to continuous contact with the brake pads of the yaw system, and the need to add grease to the brake pads to avoid them becoming too dry.

[0036] It should be noted that although grease is added to the brake pads, a large amount of carbon powder will still be generated during actual operation.

[0037] like Figure 1 This application illustrates an embodiment of a carbon dust collection device for a wind turbine yaw system brake disc. The carbon dust collection device includes: a ring-shaped dust collection disc 1 surrounding a brake caliper 200 and positioned below the brake caliper 200 and above the dust collection disc 1; and an oil collection disc 2 positioned below the brake caliper 200 and above the dust collection disc 1, wherein the oil collection disc 2 is located between two adjacent brake calipers 200.

[0038] A ring-shaped dust collection tray 1 is arranged around the lower part of the brake caliper 200. The shape of the dust collection tray 1 matches the layout of the brake disc 301 of the yaw system 300, ensuring that the dust collection tray 1 can fully cover the area of ​​carbon powder splashing generated during braking. The dust collection tray 1 is used to collect carbon powder that falls off from the brake pads 201 of the brake caliper 200 during friction with the brake pads 301 of the yaw system, preventing carbon powder from falling onto other parts of the unit or the environment, thereby keeping the unit clean. An oil collection tray 2 is arranged below the brake caliper 200 and above the dust collection tray 1. It should be noted that the oil collection tray 2 is arranged between two adjacent brake calipers 200, which ensures that the grease generated during braking friction is squeezed out and falls onto the oil collection tray 2 between the brake calipers 200. The grease will not drip directly onto the carbon powder in the dust collection tray 1, avoiding carbon powder clumping due to oil or affecting subsequent processing. The main function of the oil tray 2 is to collect the grease dripping from the brake pads, preventing the grease from directly contaminating the carbon powder in the dust tray 1, and also facilitating the collection of grease.

[0039] As shown in the accompanying drawings, both the dust collection tray 1 and the oil collection tray 2 have a tray surface and tray walls. For those skilled in the art, the toner on the dust collection tray 1 can be removed periodically, for example, by using a handheld vacuum cleaner. Preferably, a vacuuming device can be installed above the dust collection tray 1. For the oil collected in the oil collection tray 2, the oil collection tray 2 can also be cleaned or replaced periodically.

[0040] Through the above embodiments, the carbon powder collection device of this embodiment not only effectively solves the problem of difficulty in collecting the carbon powder continuously generated by the brake pads of the yaw system, but also takes into account the collection of brake pad grease, thereby improving the overall operating efficiency and maintenance convenience of the wind turbine generator set. Furthermore, the device has a simple structure, is easy to install, and is suitable for various types of wind turbine generator set yaw systems, possessing broad practicality and promotional value.

[0041] Reference Figure 1 , Figure 5 In some embodiments, the wall of the dust collection tray 1 extends downward to the bottom of the tray surface and is connected to a mounting tray 11 parallel to the dust collection tray 1. The mounting tray 11 is connected to the yaw system 300 through a mounting plate 12.

[0042] Specifically, the wall of the dust collection tray 1 is not limited to the edge of the tray surface, but extends downwards for a certain distance. This extended wall is connected to a mounting plate 11 parallel to the dust collection tray 1 below the tray surface. The mounting plate 11 is provided with threaded holes for mounting the dust collection tray 1. The mounting plate 12 serves as a connector, and the mounting plate 11 can be installed on the inner wall of the yaw system 300 by bolt connection.

[0043] Reference Figure 2 , Figure 3 In some embodiments, a screen plate 21 with several through holes is placed on the surface of the oil receiving tray 2.

[0044] Specifically, a screen plate 21 with several through holes is placed on the surface of the oil receiving tray 2. Because the grease has tension, the grease that falls onto the screen plate 21 can form tension in the mesh of the screen plate 21 and adhere to the mesh. The staff only needs to remove the mesh periodically for rinsing to clean the grease on the screen plate 21.

[0045] Reference Figure 2 , Figure 4 , Figure 5 In some embodiments, the toner collection device further includes a dust collection device 3 disposed above the dust collection tray 1.

[0046] The vacuum cleaner 3 uses the principle of negative pressure vacuuming. With its strong suction, the vacuum cleaner 3 can actively suck up the toner particles in the dust collection tray 1, which improves the efficiency of regular toner collection.

[0047] Continue to refer to Figure 5 In some embodiments, the vacuuming device 3 includes: a vacuum block 31, the vacuum block 31 having a vacuum chamber 32, the bottom of the vacuum block 31 being provided with a plurality of vacuum holes 33 penetrating the inside and outside of the vacuum chamber 32, and a dust extraction hole 34 penetrating the inside and outside of the vacuum chamber 32 being provided on one side of the vacuum block 31, the dust extraction hole 34 being connected to a vacuum pump (not shown in the figure) through a pipe.

[0048] The suction block 31 is the main body of the vacuuming device 3, and has a suction chamber 32. The suction block 31 serves as the carrier of the suction chamber 32, providing the necessary space for vacuuming operations. Simultaneously, the suction holes 33 at its bottom and the suction holes 34 on one side together form a suction channel, allowing toner to be effectively drawn into the suction chamber 32. The suction chamber 32 is a cavity inside the suction block 31 used to hold the sucked-in toner. The design of the suction chamber 32 typically considers toner collection efficiency and capacity to ensure continuous and effective operation during long-term vacuuming operations. The suction chamber 32 is a temporary storage space for the sucked-in toner; the toner is drawn into the suction chamber 32 by the negative pressure generated by the vacuum pump. The suction holes 33 are several small holes located at the bottom of the suction block 31, penetrating the inside and outside of the suction chamber 32. The size and number of suction holes 33 are typically determined based on the design requirements of the vacuuming device 3 and the size of the toner particles. The suction holes 33 are the channels through which toner enters the suction chamber 32. Under the negative pressure generated by the vacuum pump, toner particles in the air are drawn into the suction port 33 and enter the suction chamber 32. The suction port 34 is a large hole located on one side of the suction block 31, penetrating both the inside and outside of the suction chamber 32. The suction port 34 is connected to the vacuum pump via a pipe to form a negative pressure suction channel. The suction port 34 is the inlet for the vacuum pump to generate negative pressure. In summary, the vacuum pump extracts air from the suction chamber 32 through the suction port 34, creating a negative pressure environment, thereby drawing air from the suction port 33 into the suction chamber 32.

[0049] Continue to refer to Figure 4 , Figure 5 In some embodiments, at least one sidewall of the suction block 31 is provided with a brush. Optionally, the suction block 31 is provided with a brush 35a facing the surface of the dust collection tray 1. Optionally, the suction block 31 is provided with a brush 35b facing the inner wall of the yaw system below the brake disc.

[0050] A brush is positioned on at least one side wall of the suction block 31, allowing it to directly contact the surface to be cleaned. Generally, the brush is made of soft yet durable materials such as nylon or polyester, with bristle density and length ensuring effective sweeping of toner during vacuuming. As the suction block 31 moves, the brush actively sweeps up toner particles adhering to the surface, making them easier to draw into the suction chamber through the suction holes 33. The brush's sweeping action breaks down the adhesion between toner particles and the surface, improving suction efficiency. Furthermore, the brush's placement allows the vacuuming device 3 to cover a wider area during cleaning, including hard-to-reach corners and crevices. The brush's flexibility allows it to adapt to surfaces of different shapes and curvatures, enhancing the thoroughness of the cleaning process.

[0051] The brush 35a is mounted on the suction block 31, with its bristles facing the surface of the dust collection tray 1. For example... Figure 3 The suction block 31 has brushes 35a on both sides facing the surface of the dust collection tray 1. During the operation of the vacuuming device 3, the brushes 35a can sweep the surface of the dust collection tray 1 as the suction block 31 moves, sweeping up the toner particles attached to the surface of the tray, making it easier for them to be sucked into the suction chamber 32 by the suction holes 33. Through the cleaning action of the brushes 35a, it is ensured that too much toner accumulates on the dust collection tray 1, thereby maintaining the efficient operation of the vacuuming device 3.

[0052] Brush 35b is also mounted on suction block 31, but its bristles face the inner wall of the yaw system below the brake disc, as... Figure 3 The suction block 31 has brushes 35b on both sides facing the inner wall of the yaw system below the brake disc, allowing the brushes 35b to clean carbon powder on the inner wall of the yaw system. During the operation of the yaw system, carbon powder and other substances accumulate on the inner wall of the yaw system below the brake disc. The brushes 35b enable the suction device 3 to clean the inner wall of the yaw system while suctioning, maintaining its cleanliness.

[0053] Continue to refer to Figure 3 In some embodiments, the oil receiving pan 2 is installed between two adjacent brake calipers 200 via an oil receiving pan bracket 22. The installation method can be selected as a snap-fit ​​connection or a screw connection, making the installation and removal of the oil receiving pan 2 relatively simple and convenient.

[0054] Continue to refer to Figure 5In some embodiments, the vacuum block 31 is mounted between two adjacent brake calipers 200 via a vacuum block bracket 36. The vacuum block bracket 36 and the brake caliper 200 can be connected by a snap-fit ​​connection or a screw connection. The vacuum block bracket 36 makes the installation and removal of the vacuum block 31 relatively simple and convenient. When the vacuum block 31 needs maintenance or replacement, maintenance personnel can easily remove it from between the brake calipers 200 without complex disassembly of the entire braking system.
