Description

Technical Field

[0001] This utility model relates to the field of wind power generation, specifically to a portable collector ring repair device. Background Technology

[0002] In wind turbine generators, slip rings are key components inside the generator, their core function being to collect the alternating current generated by the generator and transmit it to the external circuit. To ensure efficient and stable current transmission, slip rings are typically made of materials with excellent conductivity, such as copper and forged steel. Furthermore, their sophisticated structural design not only adapts to the high-speed rotational working environment of the generator but also possesses excellent wear and corrosion resistance, ensuring long-term stable operation.

[0003] The main reasons for generator slip ring failures during long-term operation are the mechanical friction between the brushes and the slip ring, as well as the heat generated when current flows through. Due to limitations in the generator's shaft system and cooling method, the cooling conditions of the slip ring assembly are relatively poor. This causes heat to easily concentrate inside the assembly, leading to a rise in temperature and significantly increasing the risk of failures such as ring surface burning and arcing.

[0004] To reduce the frequency of slip ring failures and improve equipment reliability and lifespan, effective maintenance measures must be taken. These include regular inspections of the slip rings and timely repairs when problems are found, ensuring they are always in optimal working condition. This series of maintenance tasks not only effectively improves the power generation efficiency and operational stability of the wind power system and reduces overall operating costs, but also helps extend the service life of the entire wind power system.

[0005] In the past, due to the height of wind turbine towers, carrying tooling up the tower for repairs was extremely difficult. Typically, the collector rings needed to be removed from the tower and repaired by machining. However, in wind power and other fields, removing the collector rings for repair is extremely costly, consuming significant manpower, resources, and time, and causing prolonged downtime of the power generation equipment, resulting in power loss. Therefore, there is an urgent need to develop a portable repair device that allows for on-site repairs on the tower, reducing the need for removal from the tower and factory machining operations, thereby improving maintenance efficiency and equipment availability.

Detailed Implementation

[0039] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0040] Example 1:

[0041] A portable slip ring repair device, such as Figure 1-7 As shown, it includes a feed rate adjustment mechanism, a transverse motion mechanism, an anti-interference adjustment mechanism, and a grinding tool 3; the anti-interference adjustment mechanism includes a swing positioning seat 13, a sliding plate 7, a first guide rail 9, and a first slider 10; the grinding tool 3 is mounted on the feed rate adjustment mechanism, the first guide rail 9 is mounted on the feed rate adjustment mechanism, the first guide rail 9 is slidably connected to the first slider 10, the first slider 10 is mounted on the sliding plate 7, the sliding plate 7 is connected to the swing positioning seat 13, the swing positioning seat 13 is slidably connected to the transverse motion mechanism, and the transverse motion mechanism can drive the feed rate adjustment mechanism and the grinding tool 3 to move laterally.

[0042] The anti-interference adjustment mechanism ensures that the adjustment of the feed rate of the grinding tool 3 by the feed rate adjustment mechanism and the adjustment of the lateral grinding range of the grinding tool 3 by the lateral motion mechanism do not interfere with each other. At the same time, it enables the device to be highly integrated, compact in layout, smaller in overall size, lighter, easier to carry and install, and convenient for operators to carry it up the tower (wind power tower) to repair the collector ring.

[0043] In order to achieve the sliding connection between the swing positioning seat 13 and the transverse motion mechanism, in a specific embodiment, the swing positioning seat 13 is provided with a waist-shaped hole. The length direction of the waist-shaped hole is along the movement direction of the feed amount of the grinding tool 3. The transverse motion mechanism is set in the waist-shaped hole and can slide relative to it along the length direction of the waist-shaped hole, thereby ensuring that the position of the transverse motion mechanism in the feed amount direction of the grinding tool 3 remains unchanged during the adjustment of the feed amount of the grinding tool 3.

[0044] This invention allows for the replacement of grinding tools 3 of different sizes and specifications. The grinding tools 3 can be grinding stones, oilstones, sandpaper, cutting tools, or other materials that can be used for grinding. To accommodate different grinding tools 3, the direction of the lateral movement of the grinding tool 3 is at an angle to the direction of the feed movement, preferably perpendicular.

[0045] For ease of carrying and installation, the system also includes a housing 2, which forms an installation space. The feed rate adjustment mechanism, lateral movement mechanism, anti-interference adjustment mechanism, and grinding tool 3 are housed within this space, with the feed rate adjustment mechanism and grinding tool 3 protruding from the surface of the housing 2. The housing 2 has mounting holes for installation on the slip ring system. These mounting holes allow operators to quickly install the slip ring repair device onto the slip ring system, facilitating repairs on the tower without disassembling the slip ring for removal from the tower, reducing manpower and material costs, shortening downtime, and improving equipment availability.

[0046] Compared to traditional ring repair devices, which occupy a large space, require a lot of materials, are heavy, inconvenient to carry up the tower, and are difficult to install (requiring the removal of the entire brush holder and manual adjustment of the cutting position), this invention occupies less space, is lightweight, and can be directly carried up the tower by operators. It is easy to install, as it can directly utilize the mounting holes of the existing slip ring system without complicated disassembly and assembly procedures. After installation, the repair device can automatically operate and grind in conjunction with the rotation of the slip ring, greatly improving processing efficiency and reducing costs.

[0047] Example 2:

[0048] This embodiment is an improvement based on Embodiment 1, specifically the following improvements: Figure 1-7 As shown, the feed rate adjustment mechanism includes an adjustment screw 1 and a clamping plate 8; one end of the clamping plate 8 is provided with a grinding tool 3, and the other end of the clamping plate 8 is connected to the adjustment screw 1. The adjustment screw 1 can adjust the feed rate of the grinding tool 3 through the clamping plate 8.

[0049] The feed rate adjustment mechanism drives the clamping plate 8 to move through the adjusting screw 1, which precisely controls the feed rate of the grinding tool 3, avoiding the problem of over-grinding or under-grinding of the grinding tool 3, realizing fine repair of the surface of the slip ring, ensuring good contact between the slip ring and the brush after repair, improving the stability of current transmission, and reducing the risk of failure.

[0050] Example 3:

[0051] This embodiment is an improvement based on Embodiment 1 or Embodiment 2, specifically the following improvements: Figure 1 and Figure 4-7 As shown, the transverse motion mechanism includes a motor 6, a motor plate 4, a reciprocating motion adjustment mechanism, a second slider 11, and a second guide rail 12. The second slider 11 is mounted on a sliding plate 7 and is slidably connected to the second guide rail 12. The second guide rail 12 is mounted on the motor plate 4, and the motor 6 is also mounted on the motor plate 4. The output shaft of the motor 6 is connected to the reciprocating motion adjustment mechanism, and the reciprocating motion adjustment mechanism is slidably connected to the swing positioning seat 13.

[0052] The reciprocating motion adjustment mechanism enables the grinding tool 3 to reciprocate laterally. It can employ a cam mechanism, an eccentric wheel mechanism, or other structures that convert rotary motion into linear reciprocating motion. In one embodiment, the reciprocating motion adjustment mechanism includes an eccentric sleeve 15 and a needle roller assembly. The eccentric sleeve 15 has an eccentric hole through which the output shaft of the motor 6 passes and connects to the needle roller assembly, enabling the needle roller assembly to reciprocate laterally. The needle roller assembly includes a needle roller sleeve 14 and needles 16. The needle roller sleeve 14 is a circular sleeve, and multiple needles 16 are evenly distributed circumferentially inside the needle roller sleeve 14. The needles 16 are rolledly connected to the output shaft of the motor 6. The displacement of the needle roller assembly can be adjusted by adjusting the size of the needles 16.

[0053] The lateral motion mechanism allows the grinding tool 3 to reciprocate along the axial direction of the slip ring surface, widening the grinding range of the grinding tool and replacing manual lateral operation. Combined with the rotation of the slip ring, it achieves automatic repair and improves grinding efficiency. Adjusting the size of the needle roller 16 changes the lateral displacement of the needle roller assembly, thereby adjusting the grinding range of the grinding tool 3. This eliminates the need to replace the entire lateral motion component, reducing maintenance costs while ensuring grinding uniformity under different working conditions, improving repair quality and the applicability of the device.

[0054] Preferably, the motor 6 is equipped with a control unit, which can output torque according to the instructions of the control unit, thereby adjusting the parameters of the lateral movement to achieve automatic repair upon plugging in. Furthermore, by adjusting the lateral movement parameters, such as the speed and time period of the lateral movement, it can be adapted to the repair of different degrees of damage to the slip ring.

[0055] To facilitate speed adjustment, the lateral motion mechanism also includes a speed reducer 5, which is connected between the motor 6 and the reciprocating motion adjustment mechanism. When the speed reducer 5 is provided, its output shaft is considered to be the output shaft of the motor 6.

[0056] After the motor 6 starts, the power is transmitted to the reciprocating motion adjustment mechanism via the reducer 5 (optional, used to adjust the speed). The output shaft of the motor 6 passes through the eccentric hole on the eccentric sleeve 15 and is in rolling connection with the needle roller 16, driving the needle roller sleeve 14 to perform transverse reciprocating motion. The transverse position of the needle roller sleeve 14 (the width direction of the waist-shaped hole) is restricted by the swing positioning seat 13, which in turn drives the swing positioning seat 13 to perform transverse reciprocating motion. The swing positioning seat 13 is connected to the sliding plate 7, and the sliding plate 7 is connected to the clamping plate 8, thereby driving the grinding tool 3 to perform transverse reciprocating motion. The relative motion direction between the second slider 11 and the second guide rail 12 is the same as the transverse motion direction of the grinding tool 3. The relative motion direction between the first guide rail 9 and the first slider 10 is the same as the feed motion direction of the grinding tool 3, and the length direction of the waist-shaped hole on the swing positioning seat 13 is the same as the feed motion direction of the grinding tool 3.

[0057] The anti-interference adjustment mechanism resolves the motion conflict between feed rate adjustment and transverse grinding, ensuring stable operation of the device within the confined space of the generator. During feed rate adjustment, the adjusting screw 1 causes the clamping plate 8 to move the grinding tool 3 in the feed rate direction, which in turn moves the sliding plate 7 in the feed rate direction. The sliding plate 7 then moves the first slider 10 along the first guide rail 9, and simultaneously moves the swing positioning seat 13 along the length of its upper oblong hole, thus ensuring that the position of the transverse motion mechanism remains unchanged (the position of the output shaft of the motor 6 remains unchanged), avoiding interference.
