Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine generator sets, in particular to a device for treating residues in grooves of a cast iron platform of a wind turbine generator set. Background Art

[0002] The continuous iteration of wind turbine generator sets and their electromechanical drive systems is the basis for the continuous development of the wind power industry and also the weakest link in the verification ability of China's wind power industry. At present, China faces bottleneck constraints such as harsh environment, poor accessibility, and high operation and maintenance costs in the direction of offshore wind power test operation. There is an urgent need to build an online monitoring and detection platform for medium-speed and high-speed offshore wind turbine generator sets, develop relevant test verification technologies for testing offshore electromechanical drive systems on onshore test platforms, and achieve a leap in test verification technology innovation ability. One of the scientific and technological problems behind this is the design, maintenance, and repair of cast iron platforms.

[0003] A cast iron platform is a platform device made of cast iron material, which can effectively support heavy equipment and large workpieces and is widely used in fields such as mechanical manufacturing, wind power assembly, construction engineering, and aerospace. In the wind power industry, in order to do a good job in center construction and improve the technology and quality of tested products, the design strength of the cast iron platform meets the requirements of maximum full-power testing; at the same time, the cast iron platform needs to be regularly maintained to ensure its normal operation and extend its service life. Regular cleaning of the cast iron platform can prevent the accumulation of dust, oil, and other sundries, and at the same time reduce the risk of corrosion, greatly improving the test efficiency, safety, and economy of testing offshore electromechanical drive systems on onshore test platforms.

[0004] Since a plurality of parallel T-shaped grooves are provided on the surface of the cast iron platform. However, after long-term use, residues will remain in the T-shaped grooves of the cast iron platform. The remaining residues not only affect the installation work but also reduce the corrosion risk of the cast iron platform. Therefore, the cast iron platform needs to be regularly maintained to ensure its normal operation and extend its service life.

[0005] Most of the existing cleaning methods use a spatula. The outer dimension of the spatula is adapted to the cross-sectional dimension of the groove. During cleaning, the spatula is placed in the groove and pushed flat along the length direction of the groove to shovel off the residues on the side wall of the groove and push them out from the end of the groove. However, since some of the residues on the side wall of the groove are relatively hard or have strong adhesion, during the flat pushing process, such residues will hinder the advancement of the spatula. Therefore, during the cleaning process, it is necessary to stop to perform special treatment on such residues before shoveling, which will inevitably affect the cleaning effect and greatly reduce the work efficiency. In addition, it will also affect the service life of the spatula. Summary of the Utility Model

Detailed implementation mode

[0027] The embodiments of the technical solution of the present utility model will be described in detail below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model, so they are only examples and cannot be used to limit the protection scope of the present utility model.

[0028] Please refer to Figures 1 to 4 , the present utility model provides a device for treating the slag in the groove of the cast iron platform of a wind turbine, which includes a linear motion driving source 100, a mounting plate 200, a shovel plate 300, a shovel knife 400 and a rotary driving source 500.

[0029] Specifically, the mounting plate 200 is arranged on the linear motion driving source 100, and the linear motion driving source 100 can drive the mounting plate 200 to move along the extension direction of the groove. The shovel plate 300 is arranged on the mounting plate 200, and the outer shape of the shovel plate 300 is similar to the cross-sectional shape of the groove. There are multiple shovel knives 400, and the multiple shovel knives 400 are arranged at intervals along the edge of the shovel plate 300 in the circumferential direction.

[0030] The shovel knife 400 includes a knife handle 410 and a knife disc 420. The shovel plate 300 is a hollow plate. The knife handle 410 can rotatably insert into the inner cavity of the shovel plate 300 from the side wall of the shovel plate 300. The knife disc 420 is arranged at the end of the knife handle 410 outside the shovel plate 300. The edge of the knife disc 420 is a cutting edge, and the knife disc 420 can slidably abut against the surface of the groove. The rotary driving source 500 is arranged in the inner cavity of the shovel plate 300 and is connected to all the knife handles 410, and can drive all the knife handles 410 to rotate.

[0031] When in use, the shovel plate 300 and the shovel knife 400 thereon are inserted together from the end of the groove. Then, the rotary driving source 500 is started to drive all the knife handles 410 to drive the knife disc 420 to rotate. Then, the linear motion driving source 100 drives the mounting plate 200 and the shovel plate 300 to move forward along the groove. During the forward movement, the slag and oil adhered to the inner wall of the groove can be shoveled up, and advanced forward through the shovel plate 300 and the shovel knife 400 until it is removed from the other end of the groove.

[0032] By adopting such a device, the linear motion shoveling method of the shovel plate 300 is changed into a rotary cutting method through the rotating knife disc 420, so as to prevent the situation that the shovel knife 400 cannot move forward smoothly in the groove and shovel up the slag due to the hard slag or strong adhesion.

[0033] In addition, during the setting, it should be ensured that the cutting edges of the knife discs 420 located on the same straight line are adjacent to each other, so as to avoid the situation that the slag between two knife discs 420 is not shoveled up.

[0034] In this embodiment, the rotary drive source 500 includes a rotary power source 510, a driven gear 520, and a bevel gear 540. The rotary power source 510 is disposed inside the inner cavity of the scraper plate 300 and is connected to one of the tool holders 410, capable of driving the rotation of this tool holder 410. A driven gear 520 is sleeved on each tool holder 410, and the driven gears 520 located on the same straight line are meshed obediently. Bevel gears 540 are provided on the two end tool holders 410 located on two intersecting straight lines, and the two bevel gears 540 are meshed with each other.

[0035] During use, when the rotary power source 510 is started, through the obediently meshed driven gears 520 and the bevel gears 540 provided at the corners, all the tool holders 410 can be driven to rotate simultaneously, thereby achieving the purpose of driving all the cutter disks 420 to rotate.

[0036] As another preferred embodiment, the device further includes a front scraper 600. The front scraper 600 is disposed on the mounting plate 200 and is located in front of the scraper plate 300. The end of the front scraper 600 can be slidably clamped in the groove, and the outer wall of the end of the front scraper 600 is spaced from the side wall of the groove.

[0037] Through the front scraper 600, the dregs that are not attached to the side wall of the groove in the groove can be pushed away first, reducing the interference of these dregs on the cutter disk 420.

[0038] In addition, the device further includes a rear scraper 700. The rear scraper 700 is disposed on the mounting plate 200 and is located behind the scraper plate 300. The end of the rear scraper 700 can be slidably clamped in the groove, and the outer wall size of the end of the rear scraper 700 is adapted to the side wall size of the groove. Through the rear scraper 700, the dregs that are not pushed away by the scraper plate 300 and the shovel blade 400 can be scraped away.

[0039] For the above-mentioned wind turbine cast iron platform groove dreg treatment device, through the rotating cutter disk 420, the linear motion scraping method of the scraper plate 300 is changed to a rotary cutting method, thereby preventing the situation that the traditional shovel blade 400 cannot move forward smoothly and shovel up the dregs due to the hardness of the dregs or tight adhesion. At the same time, through the front scraper 600, the interference of the dregs in the groove on the shovel blade can be reduced, thereby improving the cleaning effect. The rear scraper 700 can shovel up and push away the dregs in the groove again, thereby improving the cleaning effect.
