Description

Technical Field

[0001] This application relates to the technical field of maintenance tools, and particularly to an oil cleaning device. Background Art

[0002] During the operation of a wind turbine generator, the bearings are responsible for ensuring the smooth operation of the rotating components. Over time and with the use of the equipment, grease and its aggregates continuously accumulate in the bearing clearance. This accumulation of grease and other contaminants can lead to bearing damage, manifested as an increase in friction, excessive heat generation, and excessive wear of components. If these problems are not addressed in a timely manner, it may result in a decrease in the efficiency of the wind turbine generator, an increase in maintenance costs, and even machine failures. Therefore, the cleaning of grease in the bearing clearance is not only a maintenance task but also a key to ensuring machine performance and extending the equipment life. If the cleaning tool itself accumulates too much grease or impurities, its efficiency during the cleaning process will decrease. Incomplete cleaning may make it difficult to remove new grease, and may even reintroduce the previous contaminants into the cleaning area. Such a situation not only reduces the efficiency of the cleaning work but may also cause additional contamination and damage to the bearings.

[0003] Currently, in the maintenance of wind turbine generators and other industrial equipment, manual cleaning tools such as scrapers, cloth pieces, and brushes are one of the most traditional methods for physically removing grease. These tools are widely used due to their simplicity and cost-effectiveness. Scrapers are used to directly scrape off the accumulated grease or adhering substances and are suitable for flat or large surfaces. Cloth pieces are used for wiping and absorbing grease, especially for the meticulous scrubbing work after cleaning. Brushes can enter irregular surfaces or mechanical gaps to help remove grease that is difficult to reach with other tools. However, these tools have significant limitations in narrow spaces, such as inside the pitch bearings of wind turbine generators. In these environments, grease usually accumulates in places that are difficult to directly observe, and traditional manual cleaning tools, due to size and shape limitations, often cannot provide effective cleaning. For example, a standard scraper may not be able to adapt to the narrow gaps between bearings, while cloth pieces and brushes may not be able to completely remove dried or hardened grease.

[0004] Based on this, although traditional cleaning tools can remove grease to a certain extent, their cleaning effect in narrow spaces is not good, and the cleaning and maintenance of these tools themselves are cumbersome and complex, and they often cannot maintain long-term cleaning efficiency. Therefore, there is an urgent need for an oil cleaning device to solve the technical problem of low oil cleaning efficiency. Utility Model Content

These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0028] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0029] In the prior art, grease cleaning tools mainly include basic manual tools such as scrapers, cloth pieces, and brushes. Although these tools can generally complete the cleaning tasks, they have obvious limitations when dealing with particularly narrow or complex spaces, such as the bearing clearance of wind turbine generators. For example, due to the limitations of size and shape, the scraper cannot effectively enter the narrow gap; although the cloth piece and the brush can contact more areas, they are not efficient in removing dry or hardened grease. In addition, the cleaning and maintenance of these tools after use are relatively cumbersome.

[0030] In view of the above technical problems, the present utility model provides an oil cleaning device, aiming to effectively solve the problem of cleaning grease in the bearing clearance of industrial equipment. It is an efficient cleaning tool that is suitable for cleaning in narrow spaces and is easy to operate and maintain. The grease scraping component with a U-shaped cross-section can penetrate into difficult-to-reach areas such as bearing clearances. This enables the grease scraping component to not only precisely fit the cleaning area but also effectively scrape off the accumulated grease. Secondly, it includes a telescopic mechanism built into the handle, which is responsible for driving the cleaning component to move along the concave surface of the grease scraping component. The design of the telescopic mechanism ensures that the cleaning component can slide along the scraping component, thereby efficiently completing the cleaning of the grease scraping component. Further, the cleaning component is equipped with a brush, which closely fits the concave surface of the grease scraping component and performs cleaning actions through the control of the telescopic mechanism. This effectively removes the grease and reduces potential damage to the surface of the grease scraping component. Finally, considering the problem of insufficient light in narrow spaces, a lighting component is equipped on the handle. This allows the operator to clearly see the working area even in low-light environments, further improving the accuracy and efficiency of the cleaning work.

[0031] The oil cleaning device of this application is mainly aimed at application scenarios in the maintenance of industrial equipment such as wind turbine generators, especially for cleaning the grease in those hard-to-reach bearing clearances. Due to its structural characteristics, the bearings in wind turbine generators are prone to accumulating grease and other contaminants in the clearances. These accumulations not only reduce the operating efficiency of the equipment but may also cause additional wear and even failures.

[0032] In order to make the above objects, features, and advantages of the embodiments of the present utility model more obvious and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0034] Such as Figures 1 to 4As shown, a grease cleaning device of the present utility model is used to clean the grease in the bearing clearance. The grease cleaning device includes a grease scraping component 10, a handle 20, and a cleaning component 30. Among them, the cross-section of the grease scraping component 10 is U-shaped, and this shape enables the grease scraping component 10 to adapt to and closely fit the inner surface of the bearing clearance, effectively scraping off the accumulated grease. Moreover, one end of the grease scraping component 10 is fixed to the handle 20 to ensure the stability and controllability during the operation of the grease cleaning device. There is a cavity inside the handle 20, and a telescopic mechanism is installed in the cavity. One end of the telescopic mechanism is connected to the cleaning component 30, and the other end is connected to the inner side wall of the cavity. The handle 20 not only serves as an operation interface, but the cavity inside it also plays an important role in installing and protecting the internal mechanism. The telescopic mechanism installed in the cavity, with one end connected to the cleaning component 30 and the other end connected to the inner side wall of the cavity, ensures the flexible mobility and reliability of the cleaning component 30.

[0035] Preferably, the outer surface of the handle 20 is covered with a rubber protective sleeve, and anti-slip stripes are provided on the rubber protective sleeve. This enhances the comfort of holding and the safety of operation. The presence of the rubber protective sleeve improves the holding stability of the operator during use, especially under wet and slippery conditions that may be encountered during the cleaning process. In addition, anti-slip stripes are designed on the protective sleeve, and these stripes increase the friction between the hand and the handle 20, further preventing slipping during operation and ensuring the accuracy and safety of the operation.

[0036] The cleaning component 30 is placed on the concave surface of the grease scraping component 10, and the bottom edge of the cleaning component 30 is arranged in contact with the concave surface of the grease scraping component 10. The cleaning component 30 is slidably connected to the grease scraping component 10 through a telescopic mechanism. The bottom edge of the cleaning component 30 is designed to be closely combined with the concave surface of the grease scraping component 10, reducing the residue of the grease on the surface of the grease scraping component 10. The telescopic mechanism enables the cleaning component 30 to make necessary adjustments and movements according to different working conditions and the degree of grease accumulation. The staff can adjust the length of the telescopic mechanism by operating the telescopic mechanism, thereby adjusting the position of the cleaning component 30 on the surface of the grease scraping component 10. The cleaning component 30 can move smoothly on the grease scraping component 10, thus realizing the continuous removal of grease and avoiding the re-accumulation of grease on the scraping component.

[0037] Preferably, the cleaning component 30 adopts a cleaning plate which is vertically placed on the concave surface of the grease scraping component 10, and the bottom edge of the cleaning plate is arranged in contact with the concave surface of the grease scraping component 10 through a brush. The bottom edge of the cleaning plate is equipped with a brush. The brush enables the cleaning plate to be closely attached to the concave surface of the grease scraping component 10, improving the efficiency and thoroughness of grease removal. When the cleaning plate moves along the grease scraping component 10, the brush closely brushes over the concave surface, effectively removing the accumulated grease and other dirt. In addition, the setting of the brush also takes into account the protection of the surface of the grease scraping component 10. By reducing direct hard scraping, the brush can protect the key components of the grease cleaning device from damage while cleaning the grease. It not only has high efficiency in removing grease, but also improves the durability of the grease cleaning device. Here, it should be noted that the material selection of the brush needs to be considered. It needs to have sufficient rigidity to remove stubborn grease and be soft enough to prevent scratching the surface of the grease scraping component 10. For example, nylon or polypropylene fibers.

[0038] To further enhance the durability of the grease device, both the grease scraping component 10 and the telescopic mechanism are made of carbon steel, ensuring the strength and durability of the grease cleaning device. The choice of carbon steel is due to its superior mechanical properties and corrosion resistance, enabling the device to maintain stable performance in various environments and not being easily damaged even under long-term contact with grease and other chemical substances. The durability of this material is particularly suitable for industrial environments that require frequent use and may encounter harsh working conditions.

[0039] When using the grease cleaning device for work, the operator holds the handle 20 and then inserts the grease scraping component 10 into the bearing clearance. During the grease scraping operation, grease will gradually accumulate on the concave surface of the grease scraping component 10. Once a large amount of grease has accumulated, the operator adjusts the telescopic mechanism. This action causes the cleaning component 30 to move along the concave surface of the grease scraping component 10, thereby pushing the accumulated grease on the surface outward. Overall, the grease cleaning device not only shows high efficiency in the initial grease scraping, but also maintains the same efficiency and thoroughness in the subsequent cleaning work, thus ensuring the cleanliness of the bearing clearance and the good operation of the equipment, and guaranteeing the performance and reliability of the equipment during long-term operation.

[0040] Furthermore, the telescopic mechanism includes a driving component and a telescopic component. The driving component is installed on the handle 20. One end of the telescopic component is connected to the driving component, and the other end is connected to the cleaning component 30. The function of the driving component is to provide the required power for the telescopic component, so as to push the cleaning component 30 to move along the grease scraping component 10, achieving effective removal of grease. Users can easily operate the cleaning tool without excessive physical effort, while maintaining the continuity and stability of the cleaning process. The telescopic component connects the driving component and the cleaning component 30. Its main function is to convert the power of the driving component into the movement of the cleaning component 30. This conversion enables the cleaning component 30 to slide smoothly along the concave surface of the grease scraping component 10, thereby achieving the purpose of removing grease.

[0041] Preferably, the driving component includes a piston 401 and a connecting rod 402. The piston 401 is installed inside the handle 20 and is arranged along the short axis of the handle 20. One end of the connecting rod 402 is connected to the telescopic component, and the other end is hinged to the driving rod of the piston 401. A compression spring 403 is provided in the cylinder cavity of the piston 401. One end of the driving rod is connected to the spring 403, and the other end passes through the side wall of the handle 20, and a button 406 is provided outside the handle 20. The function of the piston 401 is to generate power through the compression spring 403 to drive the entire cleaning process. The compression spring 403 is installed in the cylinder cavity of the piston 401. The compression and release of the spring 403 provide continuous power output for the cleaning tool. One end of the driving rod is connected to the spring 403, and the other end passes through the side wall of the handle 20, and an operation button 406 is provided outside the handle 20. Users activate the piston 401 by pressing the button 406 to start the cleaning process. The telescopic component includes an X-shaped telescopic rod 404. One end of the X-shaped telescopic rod 404 is hinged to the connecting rod 402, and the other end is connected to the cleaning component 30. One end of the connecting rod 402 is hinged to the X-shaped telescopic rod 404 of the telescopic component, and the other end is connected to the driving rod of the piston 401. The function of the connecting rod 402 is to transmit the power generated by the piston 401 to the telescopic component, ensuring that the cleaning component 30 moves smoothly along the concave side surface of the grease scraping component 10. This mechanical connection ensures effective power transmission and the sensitivity of the device operation. The X-shaped telescopic rod 404 can be moderately telescoped according to the distribution of grease and the cleaning depth to ensure that the cleaning component 30 covers the entire cleaning area. Generally speaking, the driving component and the telescopic component provide efficient, stable and flexible cleaning capabilities for the grease cleaning device, ensuring the continuity and high efficiency of the cleaning process.

[0042] On this basis, the telescopic assembly further includes a telescopic limit rod 405. Sliding holes 407 are provided at the multiple intersection centers of the X-shaped telescopic rod 404. The telescopic limit rod 405 passes through the multiple sliding holes 407 of the X-shaped telescopic rod 404 and is slidably connected to the X-shaped telescopic rod 404. This structure enables the telescopic limit rod 405 to limit and guide the movement range and direction of the X-shaped telescopic rod 404 during the process of controlling the movement of the cleaning assembly 30. It enables the cleaning assembly 30 to move more smoothly along the grease scraping assembly 10, thereby improving the cleaning efficiency and quality. One end of the telescopic limit rod 405 is connected to the inner side wall of the cavity of the handle 20, and the other end is connected to one end of the X-shaped telescopic rod 404 close to the cleaning assembly 30. This ensures the stability of the telescopic limit rod 405 during the telescopic process and prevents any loosening or deviation that may occur during the cleaning process. In addition, the connection method of the telescopic limit rod 405 also helps to maintain the structural integrity of the entire telescopic assembly, ensuring durability and reliability during long-term use.

[0043] Furthermore, the grease cleaning device further includes a lighting assembly 50, which provides lighting support for the user during grease cleaning. The lighting assembly 50 is installed on the handle 20, and the lighting direction of the lighting assembly 50 is set along the long axis direction of the grease scraping assembly 10. This ensures that the light can directly irradiate the cleaning area, especially in narrow or poorly lit environments. A battery slot 501 is provided at the bottom of the handle 20, and the battery of the lighting assembly 50 is installed in the battery slot 501. The battery slot 501 is located at the bottom of the handle 20 and is part of the energy supply for the lighting assembly 50. By integrating the battery slot 501 within the handle 20, it facilitates the installation and replacement of the battery. In addition, the lighting assembly 50 improves the flexibility and applicability of the grease cleaning device. When cleaning the grease in the bearing clearance, good lighting not only makes the cleaning work more efficient but also helps to improve the accuracy of cleaning. By providing sufficient lighting, the operator can more clearly see the details of the working area, thereby making more accurate judgments and adjustments during the cleaning process. This design consideration of the lighting assembly 50 not only enhances the user experience but also improves the safety and effectiveness of the entire cleaning process.

[0044] Based on the above embodiments, in order to reduce the adhesion of grease and lower the cleaning difficulty, preferably, a fluoropolymer coating is sprayed on both the cleaning plate and the surface of the grease scraping assembly 10. This reduces the adhesion of grease during the cleaning process. The fluoropolymer coating is known for its excellent non-stickiness and chemical stability, which makes it difficult for grease and other contaminants to accumulate on the surface of the device, thereby reducing the maintenance difficulty after the cleaning work. At the same time, this coating also helps to protect the metal surface from corrosion and extends the service life of the device.

[0045] Before using the grease cleaning device, first conduct a preparatory inspection to ensure that the device is in a working state. The operator needs to check each component, especially whether the grease scraping component 10 is firmly fixed to the handle 20, and whether the cleaning component 30 is correctly placed on the concave surface of the grease scraping component 10. At the same time, the battery compartment 501 inside the handle 20 also needs to be checked to ensure that the lighting component 50 has sufficient power for use.

[0046] In a working environment with insufficient light, first turn on the lighting component 50 to provide the necessary lighting to ensure visibility of the cleaning area. Subsequently, the operator aligns the grease scraping component 10 with the area to be cleaned in the bearing clearance and starts the cleaning work. When a certain amount of grease accumulates on the grease scraping component 10 during the cleaning process, the operator presses the button 406 on the handle 20 to activate the internal mechanism. This action drives the connecting rod 402, which in turn pushes the X-shaped telescopic rod 404 to extend, while compressing the spring 403 inside the piston 401.

[0047] The extended X-shaped telescopic rod 404 drives the cleaning plate and the brush to move along the surface of the grease scraping component 10, effectively pushing out the accumulated grease. This action achieves the purpose of cleaning the grease on the surface of the grease scraping component 10. After the cleaning is completed, the operator releases the button 406, and uses the resilience of the spring 403 to restore the driving rod to its initial position. Through this process, the X-shaped telescopic rod 404 contracts back into the inner cavity of the handle 20, returning the cleaning plate to its starting position, that is, the connection between the handle 20 and the grease scraping component 10.

[0048] The entire usage process ensures the ease of use and cleaning efficiency of the grease cleaning device in actual operation. The grease cleaning device can ensure in-depth cleaning while maintaining the stability and durability of the device.
