Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine generator sets, in particular to a cleaning device for a wind turbine generator set test platform. Background Art

[0002] The continuous evolution of wind turbines and electromechanical transmission systems is fundamental to the continued development of the wind power industry, yet it also represents its weakest link in verification capabilities. Currently, offshore wind power testing and operation faces bottlenecks such as harsh environments, poor accessibility, and high operation and maintenance costs. There is an urgent need to develop online monitoring and testing platforms for medium- and high-speed offshore wind turbines, as well as onshore test platforms to test and verify offshore electromechanical transmission systems. This will enable a leap forward in testing and verification technology innovation. One of the underlying technological challenges is the design, maintenance, and upkeep of cast iron platforms.

[0003] Cast iron platforms are constructed of cast iron and are capable of effectively supporting heavy equipment and large workpieces. They are widely used in fields such as machinery manufacturing, wind turbine installation, construction, and aerospace. In the wind power industry, to ensure effective center construction and improve the technology and quality of the products being tested, cast iron platforms are designed to meet the requirements of maximum full-power testing. At the same time, cast iron platforms require regular maintenance and servicing to ensure proper operation and extend their service life. Regular cleaning of cast iron platforms prevents the accumulation of dust, oil, and other debris, while also reducing the risk of corrosion. This significantly improves the efficiency, safety, and cost-effectiveness of testing offshore electromechanical transmission systems on land-based test platforms.

[0004] However, conventional cast iron platforms are generally cleaned with ordinary brushes, which have a small cleaning area and low cleaning efficiency. Some mop-type brushes can relatively increase the cleaning area, but the cleaning layer of such brushes is inconvenient to replace. At the same time, it is easy to be loose after replacement, and the cleaning layer is prone to loosening during the cleaning process, causing the cleaning layer to rub together, which not only affects the cleaning effect, but also shortens the life of the cleaning layer.

DETAILED DESCRIPTION

[0028] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0029] See Figures 1 to 3 The utility model provides a cleaning device for a wind turbine test platform, comprising a cleaning plate 100 , an operating rod 200 , a cleaning layer 300 and a fixer 400 .

[0030] Specifically, the operating lever 200 is disposed on the top of the cleaning plate 100. The cleaning layer 300 is a flexible body that covers the bottom surface of the cleaning plate 100, and the length and width dimensions of the cleaning layer 300 are larger than the length and width dimensions of the cleaning plate. The fixing device 400 is disposed on the top surface of the cleaning plate 100 and is used to removably clamp the four length and width edges of the cleaning layer 300 and can pull the four length and width edges of the cleaning layer 300 toward the center to secure and tighten the cleaning layer 300.

[0031] When in use, after the cleaning layer 300 is fixed, the cleaning plate 100 is moved along the surface of the cast iron by the operating rod 200 to clean the surface of the cast iron by passing through the cleaning layer 300.

[0032] When the cleaning layer 300 needs to be replaced, the fixture 400 is loosened, the old cleaning layer 300 is removed, and a new cleaning layer 300 is covered on the cleaning plate 100. The length and width of the cleaning layer 300 are clamped on the fixture 400. Then, the four sides of the cleaning layer 300 are retracted inward through the fixture 400, so that the cleaning layer 300 can be firmly fixed and flattened.

[0033] By adopting this cleaning device, the single cleaning area can be increased. At the same time, after fixing the four sides of the cleaning layer 300, the fixer 400 can pull the four sides of the cleaning layer 300 inward, thereby pulling the cleaning layer 300 flat, thereby improving the cleaning effect. In addition, by pulling, tightening, flattening and fixing the cleaning layer 300, the phenomenon of rubbing against each other during the cleaning process can be reduced, thereby extending the life of the cleaning layer 300.

[0034] When implementing, the cleaning layer 300 that outer layer is provided with bristle can be selected to improve cleaning effect.In addition, also can say operating rod 200 is connected with cleaning plate 100 hinged modes, and operating rod 200 makes its length adjustable, easy to operate.

[0035] Specifically, the fixture 400 includes a reel 410, a clamp 420, and a rotary drive 430. There are four reel rods 410, which are rotatably arranged on the cleaning plate 100 in pairs in the length and width directions of the cleaning plate 100. Each reel rod 410 is provided with a clamp 420. The rotary drive 430 is provided on the cleaning plate 100 and connected to the four reel rods 410. The rotary drive 430 can drive the four reel rods 410 to rotate simultaneously, with the rotation directions of the two opposing reel rods 410 being opposite. When the four edges of the length and width directions of the cleaning layer 300 are clamped and fixed on the four clamps 420, the rotary drive 430 can simultaneously reel in or unreel the four edges of the cleaning layer 300 through the four reel rods 410.

[0036] When in use, first fix the four sides of the cleaning layer 300 in the length and width directions on the four clamps 420 respectively, and then drive the rolling rod 410 connected to it to rotate clockwise through the rotating driving member 430, so that the rolling rod 410 parallel to this rolling rod 410 can be driven to rotate counterclockwise, and at the same time, the two rolling rods 410 perpendicular to this rolling rod 410 are driven to roll inward relative to each other, so that the four sides of the cleaning layer 300 can be wrapped around the rolling rod 410, and the four sides of the cleaning layer 300 can be pulled inward, thereby pulling the cleaning layer 300 flat. On the contrary, when the rolling rod 410 connected to the rotating driving member 430 is driven to rotate counterclockwise, the rolling rod 410 parallel to it can be driven to rotate clockwise, and the other two rolling rods 410 can rotate outward relative to each other, that is, the four rolling rods 410 rotate outward relative to each other, so that the cleaning layer 300 can be loosened.

[0037] In this embodiment, the rotary drive member 430 includes a rotary power source 431, a transmission member 432, a first bevel gear 433 and a second bevel gear 434. The rotary power source 431 is fixed to the cleaning plate 100, wherein one of the reels 410 is coaxially connected to the rotation axis of the rotary power source 431, and the transmission member 432 is connected between the reel 410 connected to the rotary power source 431 and the reel 410 parallel to the reel 410. When the rotary power source 431 rotates, the transmission member 432 can drive the two reels 410 to rotate in opposite directions. Two first bevel gears 433 are fixedly mounted on the reel 410 connected to the rotary power source 431 at intervals, and the taper directions of the two first bevel gears 433 are opposite. The two reels 410 perpendicular to the rotation axis of the rotary power source 431 are both mounted with second bevel gears 434, and the two second bevel teeth are respectively engaged with the two first bevel gears 433.

[0038] In a specific implementation, the rotation power source 431 can be a rotation motor or manual rotation method commonly used in the prior art.

[0039] When the rotary power source 431 starts to rotate, the four rolling rods 410 can be driven to rotate inward at the same time through the transmission member 432, the first bevel gear 433 and the second bevel gear 434, so that the cleaning layer 300 can be tightened. On the contrary, the four rolling rods 410 can be driven to rotate outward at the same time, so that the cleaning layer 300 can be loosened.

[0040] In this embodiment, the clamp 420 includes a fixing plate 421, a pressing plate 421 and a bolt assembly 423. The fixing plate 421 is fixed to the rolling rod 410, and the pressing plate 421 is movably covered on the pressing plate 421 and connected to the pressing plate 421 via the bolt assembly 423.

[0041] During use, when the bolt assembly 423 is loosened, pull the pressure plate 421 to create a gap between the pressure plate 421 and the fixed plate 421, and then insert the end of the cleaning layer 300 into the gap, then loosen the pressure plate 421, and then fix the fixed plate 421 and the pressure plate 421 by the bolt assembly 423, so that the cleaning layer 300 can be clamped and fixed on all sides.

[0042] Specific usage of the above-mentioned wind turbine test platform cleaning device:

[0043] During use, the cleaning layer 300 is first laid on the cleaning plate 100, and then the length and width of the cleaning layer 300 are clamped by the clamps 420, and then the rotary power source 431 is started to drive the four winding rods 410 to rotate inward relative to each other, so that the four sides of the cleaning layer 300 can be wound around the winding rods 410, and the cleaning layer 300 can be tightened and flattened, and then the cast iron platform is cleaned by the operating rod 200. When the cleaning layer 300 needs to be replaced, the four winding rods 410 are first driven to rotate outward relative to each other by the rotary power source 431, and the four sides of the cleaning layer 300 are loosened until the clamps 420 are exposed, and then the bolt assembly 423 is loosened, the old cleaning layer 300 can be removed, and the new cleaning layer 300 can be installed.

[0044] By using this cleaning device, the single cleaning area can be increased. At the same time, after the fixer 400 fixes the four sides of the cleaning layer 300, the four sides of the cleaning layer 300 can be pulled inward, thereby pulling the cleaning layer 300 flat, thereby improving the cleaning effect. In addition, by pulling and tightening the cleaning layer 300, the phenomenon of rubbing against each other during the cleaning process can be reduced, thereby extending the life of the cleaning layer 300.
