Description

Technical Field

[0001] The utility model relates to the technical field of radiator fin cleaning, in particular to a gear box radiator fin cleaning tool. Background Art

[0002] Gearbox heat sinks used in wind turbines primarily ensure that the gearbox maintains a safe temperature during operation, preventing overheating that can lead to performance degradation, shortened lifespan, or even damage. The gearbox is a key component in wind turbines. Using a multi-stage gear transmission, the gearbox increases the rotor's low speed to a suitable high speed for generator power generation, meeting the generator's required speed. During mechanical operation, the gearbox generates significant heat due to friction and internal energy conversion.

[0003] The heat sink absorbs this heat and transfers it to the surrounding environment using its good thermal conductivity, thereby maintaining the operating temperature of the gearbox at an appropriate level.

[0004] Heat sinks are usually made of materials that are resistant to high temperatures and have good thermal conductivity, such as aluminum alloy, copper, or bronze. In terms of design, the structure and size of the heat sink will also affect the heat dissipation effect. For example, increasing the heat dissipation area can improve heat dissipation efficiency.

[0005] In wind turbine gearboxes, heat sinks can be in different forms, such as tube-fin type, tube-belt type or new tube-core structure, to adapt to different heat dissipation requirements and operating environments; as the gearbox runs for a long time, a thick layer of mud and catkins will adhere to the surface of the heat sink, resulting in insufficient heat dissipation of the heat sink. After entering the high temperature season, the gearbox oil temperature and component high temperature failures are prone to occur frequently, seriously affecting the internal heat dissipation efficiency of the gearbox; therefore, the gearbox heat sink needs to be cleaned in time.

[0006] Traditional cleaning methods for gearbox heat sinks mostly involve brushing the outer surface of the heat sink. Gearbox heat sinks are over 10cm thick, so this method cannot clean the inside of the gearbox. High-pressure water jets are more effective, but this method is prone to turbulent water splashing, leading to corrosion of metal parts and electrical component failures. Furthermore, the flushing water is difficult to collect and consumes a lot of water.

[0007] In addition, since the height of wind turbines is generally above 100m, cleaning water needs to be transported from the ground to the upper unit during cleaning. If the transported cleaning water is used up, it needs to be transported again, which takes too long and affects the cleaning progress. Utility Model Content

DETAILED DESCRIPTION

[0030] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner, and thus only show components related to the present invention.

[0031] Please refer to Figure 1 A gear box heat sink cleaning tool includes a funnel-shaped waterproof cloth 1, the port of the waterproof cloth 1 is rectangular, a drainage channel 6 is provided under the waterproof cloth 1, the drainage channel 6 is connected to the filter cartridge 7, the bottom of the filter cartridge 7 is provided with a drainage pipe 8, the top port of the waterproof cloth 1 is rectangular, and ropes 5 (with hooks) and magnetic patches 4 are provided around the waterproof cloth 1. The waterproof cloth 1 is connected to the gear box heat sink above through the ropes 5 and the magnetic patches 4.

[0032] Before use, first open the port of the waterproof cloth 1, then fix the waterproof cloth 1 directly under the gear box heat sink through the rope 5 and the magnetic patch 4. After fixing, use a high-pressure water gun to flush the heat sink to wash away the attached mud and catkins; at this time, the flushing water, mud and catkins fall into the waterproof cloth 1 together, and enter the filter cartridge 7 through the drainage channel 6. The filter cartridge 7 filters impurities such as mud and catkins, and the filtered water is discharged through the drain pipe 8 and can continue to be used by the high-pressure water gun, which can meet the circulation of cleaning water and is conducive to saving resources.

[0033] In this embodiment, the waterproof cloth 1 is provided with ribs 2 on the inner side of the top port. The four ribs 2 stretch the port of the waterproof cloth 1. After the waterproof cloth 1 is stretched, its cross-section is larger than the bottom surface of the heat sink, which is convenient for better receiving cleaning water.

[0034] See also Figure 2-5 Specifically, the rib 2 includes a first support rod 21 and a second support rod 22. The end of the first support rod 21 is provided with an arc-shaped cover 211, and a first magnetic sheet 212 is provided in the arc-shaped cover 211. The end of the first support rod 21 is provided with a U-shaped connecting rod 213 in the arc-shaped cover 211, and the end of the second support rod 22 is provided with a C-shaped connecting buckle 222 that cooperates with the connecting rod 213. A second magnetic sheet 221 corresponding to the first magnetic sheet 212 is provided on the circumference of the end of the second support rod 22.

[0035] When the waterproof cloth 1 is in use, the connecting buckle 222 is buckled onto the connecting rod 213 , and the first magnetic sheet 212 and the second magnetic sheet 221 are attracted to each other.

[0036] When the waterproof cloth 1 is folded and stored after use, the connecting buckle 222 is separated from the connecting rod 213 .

[0037] The first support rod 21 and the second support rod 22 are both sewn into the waterproof cloth 1 , and the first support rod 21 and the second support rod 22 can move within the waterproof cloth 1 .

[0038] In this embodiment, the first support rod 21 and the second support rod 22 are both made of metal or hard plastic, ensuring that the first support rod 21 and the second support rod 22 can move inside the waterproof cloth; when in use, the first support rod 21 and the second support rod 22 are close to each other, so that the connecting buckle 222 is engaged with the connecting rod 213; after use, the first support rod 21 and the second support rod 22 are separated towards each other, so that the connecting buckle 222 is detached from the connecting rod 213; it is more convenient to use.

[0039] After use, the waterproof cloth 1 can be folded diagonally for storage.

[0040] As a preferred solution, a drainage mesh 3 is laid inside the waterproof cloth 1, and the drainage mesh 3 is fixed inside the waterproof cloth 1 by Velcro 31 at the four corners; the establishment of the drainage mesh 3 can perform preliminary filtration on the flushing water, thereby reducing the filtration pressure of the filter cartridge 7.

[0041] In this embodiment, the specific structure of the filter cartridge can be found in Figure 6-10 The filter cartridge 7 includes a top cover 71 and an outer cartridge 72. The top cover 71 and the outer cartridge 72 are detachably connected via threads. A pipe connected to the drainage channel 6 is provided on the surface of the top cover 71. A filtering mechanism is provided inside the outer cartridge 72. The cleaning water is filtered through the filtering mechanism after entering the filter.

[0042] The filtering mechanism includes an extension tube 73 and a filter element 74. The extension tube 73 is fixed to the inner side of the top cover 71. The filter element 74 is detachably fixed to the port of the extension tube 73. The interior of the filter element 74 is filled with quartz filter balls and activated carbon. The quartz filter balls and activated carbon can filter the washed impurities and perform preliminary separation of water and impurities. A first filter hole 741 is provided on the circumference of the filter element 74, and an overflow hole 731 is provided on the top circumference of the extension tube 73.

[0043] During use, flushing water enters the filter element 74 through the drainage channel 6 and the extension tube 74 . After entering the filter element 74 , it is first preliminarily filtered through the quartz filter ball and activated carbon; the filtered water is discharged through the first filter hole 741 .

[0044] Furthermore, a fixed support plate 77 is provided in the outer cylinder 72, an inner cylinder 75 is provided on the support plate 77, the filter element 74 is suspended in the inner cylinder 75, a second filter hole 751 is provided on the circumference of the inner cylinder 75, a filter cotton 76 is provided on the inner wall of the inner cylinder 75, and the top of the inner cylinder 75 is connected to the top cover 71.

[0045] The flushing water enters the inner cylinder 75 through the first filter hole 741, and then passes through the filter cotton 76 for secondary filtration. After the secondary filtration, the filtered water is discharged at the second filter hole 751, thereby achieving two filtrations to ensure the quality of the circulating water.

[0046] After using for a period of time, impurities will block the first filter hole 741. At this time, rotate the top cover 71 and remove the associated filter element 74 for cleaning. If the filter element 74 is not cleaned in time, the first filter hole 741 will be blocked. At this time, the cleaning water entering the extension tube 73 will flow directly into the inner tube 75 through the overflow hole 731 and be directly filtered through the filter cotton to avoid congestion of the cleaning water.

[0047] As a preferred solution, the bottom of the inner cylinder 75 is provided with an I-shaped positioning recess 752, and the surface of the support plate 77 is provided with a protrusion that cooperates with the positioning recess 752. The inner cylinder 752 can be removed from the support plate 77, and the surface of the support plate 77 is evenly provided with water grooves 771; the water filtered from the inner cylinder 75 passes through the water grooves 771 into the drain pipe 8, thereby collecting the filtered water.

[0048] In this embodiment, the inner cylinder 75 is directly placed on the support plate 77 through the positioning recess 752, and the top cover 71 is in contact with the end of the inner cylinder 75; if the inner cylinder 75 needs to be removed for cleaning, it is only necessary to open the end cover 71.

[0049] In this embodiment, the outer cylinder 72 is transparent, and the internal filtering conditions can be directly observed.

[0050] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
