Description

Technical Field

[0001] The invention relates to the technical field of heat sink cleaning, and in particular to a gear box heat sink cleaning tool. Background Art

[0002] The main function of the gearbox heat sink used in wind turbines is to ensure that the temperature of the gearbox is controlled within a safe range during operation to avoid performance degradation, shortened life or even damage due to overheating. In wind turbines, the gearbox is a key component. The gearbox uses multi-stage gear transmission to increase the low speed of the wind wheel to a high speed suitable for generator power generation according to a certain transmission ratio to meet the speed requirements of the generator. During mechanical operation, the gearbox will generate a lot of 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 the heat dissipation efficiency.

[0005] In wind turbine gearboxes, heat sinks can be in different forms, such as tube-fin type, tube-belt type or a 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] The traditional cleaning method of gearbox heat sink is to clean the outer surface of the heat sink with a brush. The thickness of the gearbox heat sink is more than 10cm. This method cannot clean the inside of the gearbox. Flushing with a high-pressure water gun has a better effect. However, this flushing method is prone to sewage turbulence splashing, causing metal parts to rust and electrical components to fail. In addition, the flushing water is not easy to collect and consumes a lot of water. In addition, since the height of wind turbines is generally more than 100m, cleaning water needs to be transported from the ground to the upper units 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. Summary of the invention

[0007] The purpose of the present invention is to solve the above-mentioned problem and provide a device that can effectively receive and collect flushing water from a high-pressure water gun, and the cleaning water can also be filtered after being collected to achieve recycling of the cleaning water, which is beneficial to saving water resources.

DETAILED DESCRIPTION

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and thus only show the components related to the present invention.

[0030] Please refer to Figure 1 A gear box heat sink cleaning tool comprises a funnel-shaped waterproof cloth 1, the port of the waterproof cloth 1 is rectangular, a drainage channel 6 is provided below the waterproof cloth 1, the drainage channel 6 is connected to a filter cartridge 7, a drainage pipe 8 is provided at the bottom of the filter cartridge 7, the top port of the waterproof cloth 1 is rectangular, ropes 5 (with hooks) and magnetic tiles 4 are provided around the waterproof cloth 1, and the waterproof cloth 1 is connected to the gear box heat sink above through the ropes 5 and the magnetic tiles 4.

[0031] Before use, first open the port of the waterproof cloth 1, then fix the waterproof cloth 1 directly below the gear box heat sink by means of the rope 5 and the magnetic patch 4, and after fixation, use a high-pressure water gun to rinse 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 together they pass through the drainage channel 6 into the filter cartridge 7, the filter cartridge 7 filters the mud, catkins and other impurities, and the filtered water is discharged through the drain pipe 8, which can continue to be used by the high-pressure water gun, thereby satisfying the circulation of cleaning water and helping to save resources.

[0032] In this embodiment, the waterproof cloth 1 is provided with ribs 2 on the inner side of the top port, and 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, so as to better receive the cleaning water.

[0033] 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 cover 211, and a first magnetic sheet 212 is provided in the arc cover 211, the end of the first support rod 21 is provided with a U-shaped connecting rod 213 in the arc cover 211, the end of the second support rod 22 is provided with a C-shaped connecting buckle 222 matched with the connecting rod 213, and the end circumference of the second support rod 22 is provided with a second magnetic sheet 221 corresponding to the first magnetic sheet 212.

[0034] When the waterproof cloth 1 is in use, the connecting buckle 222 is buckled on the connecting rod 213 , and the first magnetic sheet 212 and the second magnetic sheet 221 are attracted to each other.

[0035] When the waterproof cloth 1 is stored and folded after use, the connecting buckle 222 is separated from the connecting rod 213 .

[0036] 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 in the waterproof cloth 1 .

[0037] 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 in 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.

[0038] After use, the waterproof cloth 1 can be folded diagonally for storage.

[0039] 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 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.

[0040] In this embodiment, the specific structure of the filter cartridge can be found in Figure 6-10 The filter cartridge 7 comprises 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, and the cleaning water is filtered through the filtering mechanism after entering.

[0041] 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 to perform preliminary separation of water and impurities. The circumference of the filter element 74 is provided with a first filter hole 741, and the top circumference of the extension tube 73 is provided with an overflow hole 731.

[0042] When in use, flushing water enters the filter element 74 through the drainage channel 6 and the extension tube 74 , and after entering the filter element 74 , it is firstly filtered through the quartz filter ball and activated carbon; the filtered water is discharged through the first filter hole 741 .

[0044] 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.

[0045] After using for a period of time, impurities will block the first filter hole 741. At this time, rotate the top cover 71 to remove and clean the associated filter element 74. 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.

[0046] As a preferred embodiment, an I-shaped positioning recess 752 is provided at the bottom of the inner cylinder 75, and a protrusion that cooperates with the positioning recess 752 is provided on the surface of the support plate 77. The inner cylinder 752 can be taken out from the support plate 77, and a water groove 771 is evenly provided on the surface of the support plate 77; the water filtered from the inner cylinder 75 passes through the water groove 771 into the drain pipe 8, thereby collecting the filtered water.

[0047] 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 taken out for cleaning, it is only necessary to open the end cover 71.

[0048] In this embodiment, the outer cylinder 72 is transparent, and the internal filtering conditions can be directly observed.

[0049] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
