Description

Technical Field

[0001] The utility model relates to the technical field of radiating fins of a gear box of a wind turbine generator set, in particular to an isolating device for radiating fins of a gear box. Background Art

[0002] A large amount of heat will be generated during the operation of the wind turbine gearbox. In order to ensure that the wind turbine gearbox works continuously within the set temperature, the wind turbine gearbox is generally equipped with a heat sink, which is connected to the gearbox. The lubricating oil in the gearbox can be introduced into the heat sink for air cooling, thereby ensuring the continuous operation of the wind turbine.

[0003] Affected by the geographical location of wind turbine construction, for example, there are more poplar and willow catkins in the northern plains in summer. During the poplar and willow catkin season from April to May, the wind turbine gearbox heat sink is prone to absorb a large amount of poplar and willow catkins, causing radiator blockage and poor cooling effect of wind turbine gearbox oil. For wind power companies, this will cause high gearbox oil temperature and shutdown, affecting the operating efficiency of wind turbines.

[0004] Usually, when the gearbox heat sink is clogged, the common measures are: maintenance personnel carry cleaning water, high-pressure water guns, wastewater collection rain cloths, power cords and other equipment to climb the wind turbine and manually clean the gearbox heat sink. The cleaning process is very cumbersome, time-consuming and labor-intensive, and the cleaning efficiency is low. In wind farms with many wind turbines, insufficient maintenance personnel often cause large-scale shutdown of wind turbines due to excessive gearbox oil temperature in hot weather. Utility Model Content

[0005] The technical problem to be solved by the utility model is: how to prevent the gear box heat sink from easily sucking in a large amount of debris such as poplar and willow catkins, thereby causing radiator blockage.

[0006] The technical solution of the utility model to solve the above technical problems is as follows:

[0007] The utility model provides a gear box heat sink isolation device, comprising a heat sink body, an isolation net, a first frame, and a second frame, wherein one side of the first frame is bonded to the heat sink body, and at least a part of the heat dissipation area of ​​the first frame and the heat sink body overlap; one side of the second frame and the other side of the first frame are mutually adhered and connected by magnetic attraction, and the edge of the isolation net is bonded and fixed to the other side of the second frame.

[0008] The beneficial effects of the utility model are:

[0009] By adopting the utility model, the heat sink body is covered with an isolation net, so that foreign debris such as catkins can be isolated from the heat sink, avoiding the heat sink from sucking in debris and causing blockage, thereby ensuring the continuous operation of the heat sink; the second frame is connected to the first frame by magnetic attraction, so that the isolation net attached to the second frame can be directly removed to clean up the debris, which is convenient for disassembly and assembly, with small maintenance workload, and greatly reduced maintenance costs.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, the first grid and the second grid are both in the shape of tilable polygons.

[0012] When the heat sink body is relatively large, it is convenient to closely spread a plurality of first sashes, thereby covering the entire heat dissipation area of ​​the heat sink body, thereby reducing the size requirement for the device and facilitating transportation and installation.

[0013] Furthermore, the first grid includes a first fixed block and a first magnetic strip, and a plurality of first fixed blocks and a plurality of first magnetic strips are arranged alternately and form a polygon, the first fixed blocks are all located at the corners of the polygon and form the corners of the polygon, and the two ends of the first magnetic strip are respectively bonded to two adjacent first fixed blocks; one side of the first magnetic strip is bonded to the heat sink body; the second grid is connected to the first magnetic strip by magnetic attraction.

[0014] The spacing of the first fixing blocks and the length of the first magnetic strip determine the size of the first grid, which can be assembled on site and adjusted at will, so that it can be arranged according to the size of the heat sink body on site, has good flexibility, and is easy to transport; the first magnetic strip can be adsorbed by the second grid, providing a fulcrum for the installation of the second grid.

[0015] Furthermore, a first groove is provided on one side of the first fixing block, and an end portion of the first magnetic strip is located in the first groove.

[0016] The installation strength of the two ends of the first magnetic strip is improved to prevent the first fixing block from being lifted up when the second frame is removed, thereby preventing the gap between the first fixing block and the heat sink body from increasing.

[0017] Furthermore, one side of the first magnetic strip is flush with one side of the first fixing block.

[0018] This facilitates reducing the gap between the first fixing block and the heat sink body, improves the isolation effect, and prevents catkins from entering the heat sink body through the gap.

[0019] Furthermore, the second frame includes a second fixed block, a second magnetic strip and a hard decorative strip. A plurality of second fixed blocks and a plurality of second magnetic strips are arranged alternately and form a polygon. The second fixed blocks are all located at the corners of the polygon and form the corners of the polygon.

[0022] It is convenient to improve the installation strength of the second magnetic strip and the hard decorative strip, so that the second frame has high strength and good stability; at the same time, the gap between the second fixing block and the first fixing block is reduced to prevent catkins from entering the heat sink through the gap.

[0023] Furthermore, the width of the third groove is greater than that of the second groove, and the third groove is connected to the second groove; the second magnetic strip and the hard decorative strip are attached and bonded to each other.

[0024] Through the different widths of the grooves, a step surface is formed at the bottom of the third groove, and the step surface can be used to position the hard decorative strip. The second magnetic strip is positioned through the hard decorative strip, thereby avoiding deformation of the second magnetic strip to produce gaps, ensuring that the second magnetic strip fits tightly with the first magnetic strip and has a good isolation effect.

[0025] Furthermore, the corner of the second fixing block is connected to the corner of the first fixing block via a locking nail.

[0026] It is convenient to realize the positioning of the second frame and the first frame, and has an anti-loosening effect to prevent the magnetic attraction structure from accidentally falling off.

DETAILED DESCRIPTION

[0036] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0037] This utility model refers to Figure 1-5 .

[0038] The utility model provides a gearbox heat sink isolation device, comprising a heat sink body 1, an isolation net 2, a first frame, and a second frame, wherein one side of the first frame is bonded to the heat sink body 1, and at least part of the heat dissipation area of ​​the first frame overlaps with that of the heat sink body 1; one side of the second frame and the other side of the first frame are attached to each other and connected by magnetic attraction, and the edge of the isolation net 2 is bonded and fixed to the other side of the second frame.

[0039] principle:

[0040] At least part of the heat dissipation area: When the heat sink body 1 is small, the first frame overlaps with the entire heat dissipation area of ​​the heat sink body 1, that is, the entire heat dissipation area of ​​the heat sink body 1 is located in the first frame. At this time, the second frame fixed with the isolation net 2 is attached to the first frame, and the second frame is automatically adsorbed and fixed to the first frame by magnetic attraction to complete the installation. The isolation net 2 can cover the entire heat dissipation area of ​​the heat sink body 1. When the heat sink body 1 is large, multiple isolation devices are installed at the same time, and the first frame and the second frame are in a shape that can be closely laid. Each first frame overlaps with part of the heat dissipation area of ​​the heat sink body 1 until the entire heat dissipation area of ​​the heat sink body 1 is covered, so that the combination of multiple isolation nets 2 covers the entire heat dissipation area of ​​the heat sink body 1.

[0041] The isolation net 2 covers the entire heat dissipation area of ​​the heat sink body 1, which can prevent the heat sink from absorbing debris such as catkins, and at the same time, does not affect the air entering the heat sink. When a certain amount of catkins accumulates on the isolation net 2, the operator only needs to remove the second frame and knock and vibrate the isolation net 2 a few times to complete the cleaning, and then stick it back on the first frame, which is convenient for cleaning.

[0042] In summary, by adopting the utility model, the heat sink body 1 is covered by the isolation net 2, so that the external debris such as catkins can be isolated from the heat sink, avoiding the heat sink from sucking in debris and causing blockage, and ensuring the continuous operation of the heat sink; the second frame is connected to the first frame by magnetic attraction, so that the isolation net 2 attached to the second frame can be directly removed to clean up the debris, which is convenient for disassembly and assembly, with small maintenance workload, greatly reducing the maintenance cost.

[0043] Furthermore, the first grid and the second grid are both in the shape of tilable polygons.

[0044] Dense polygons: Dense polygons are made by joining together plane polygons of exactly the same shape and size, which can be tiled into a single piece without leaving any gaps or overlaps.

[0045] When the heat sink body 1 is relatively large, it is convenient to closely spread a plurality of first grids, thereby covering the entire heat dissipation area of ​​the heat sink body 1, thereby reducing the size requirement for the device and facilitating transportation and installation.

[0046] Further, such as Figure 2-3 As shown: the first grid includes a first fixed block 3 and a first magnetic strip 4, a plurality of first fixed blocks 3 and a plurality of first magnetic strips 4 are arranged alternately and enclosed in a polygon, the first fixed blocks 3 are all located at the corners of the polygon and form the corners of the polygon, the two ends of the first magnetic strip 4 are respectively bonded to two adjacent first fixed blocks 3; one side of the first magnetic strip 4 is bonded to the heat sink body 1; the second grid is connected to the first magnetic strip 4 by magnetic attraction.

[0047] The spacing between the first fixing blocks 3 and the length of the first magnetic strip 4 determine the size of the first grid, which can be assembled on site and adjusted at will, so that it can be arranged according to the size of the heat sink body 1 on site, has good flexibility, and is convenient for transportation; the first magnetic strip 4 can be adsorbed by the second grid, providing a fulcrum for the installation of the second grid.

[0048] Furthermore, a first groove 5 is provided on one side of the first fixing block 3 , and an end portion of the first magnetic strip 4 is located in the first groove 5 .

[0049] The installation strength of the two ends of the first magnetic strip 4 is improved to prevent the first fixing block 3 from being lifted up when the second frame is removed, thereby preventing the gap between the first fixing block 3 and the heat sink body 1 from increasing.

[0050] Furthermore, one side of the first magnetic strip 4 is flush with one side of the first fixing block 3 .

[0051] This facilitates reducing the gap between the first fixing block 3 and the heat sink body 1 , improves the isolation effect, and prevents catkins from entering the heat sink body 1 through the gap.

[0052] Further, such as Figure 1 , 2 4: the second frame includes a second fixed block 6, a second magnetic strip 7 and a hard decorative strip 8, a plurality of second fixed blocks 6 and a plurality of second magnetic strips 7 are arranged alternately and surround a polygon, the second fixed blocks 6 are located at the corners of the polygon and form the corners of the polygon, the two ends of the second magnetic strip 7 are respectively bonded to one side of two adjacent second fixed blocks 6; the hard decorative strip 8 overlaps with the second magnetic strip 7, the two ends of the hard decorative strip 8 are respectively bonded to the other side of two adjacent second fixed blocks 6, and the isolation net 2 is bonded to the hard decorative strip 8; the side of the second magnetic strip 7 away from the hard decorative strip 8 is opposite to the first magnetic strip 4.

[0053] Hard decorative strips 8: Use hard materials such as raw rubber, hard plastic, wood, metal, etc., and exclude soft materials such as cloth and cooked rubber.

[0054] The hard decorative strip 8 can stabilize the shape of the second frame, facilitate the installation of the isolation net 2, and facilitate the overall fit of the second frame to the first frame, making installation easy; the second magnetic strip 7 is directly opposite to the first magnetic strip 4, thereby improving the magnetic connection force and providing good stability.

[0055] Furthermore, a second groove 9 is provided on one side of the second fixing block 6 , a third groove 10 is provided on the other side of the second fixing block 6 , an end of the second magnetic strip 7 is provided in the second groove 9 , and an end of the hard decorative strip 8 is provided in the third groove 10 .

[0056] Note: Figure 4 In the figure, the dotted line indicates that the outline of the third groove 10 is not visible. Figure 4 The rear view perspective is visible.

[0057] It is convenient to improve the installation strength of the second magnetic strip 7 and the hard decorative strip 8, so that the second frame has greater strength and better stability; at the same time, the gap between the second fixing block 6 and the first fixing block 3 is reduced to prevent catkins from entering the heat sink through the gap.

[0058] Furthermore, the width of the third groove 10 is greater than the width of the second groove 9, and the third groove 10 is connected to the second groove 9; the second magnetic strip 7 and the hard decorative strip 8 are attached and bonded to each other.

[0059] Through the different widths of the grooves, a step surface is formed at the bottom of the third groove 10, and the step surface can be used to position the hard decorative strip 8. The second magnetic strip 7 is positioned through the hard decorative strip 8, thereby avoiding deformation of the second magnetic strip 7 to produce a gap, ensuring that the second magnetic strip 7 is tightly fitted with the first magnetic strip 4, and the isolation effect is good.

[0060] Further, such as Figure 1-5 As shown: the corner of the second fixing block 6 is connected to the corner of the first fixing block 3 via a locking nail 13.

[0061] It is convenient to realize the positioning of the second frame and the first frame, and has an anti-loosening effect to prevent the magnetic attraction structure from accidentally falling off.

[0062] Further, such as Figure 3-5 As shown: the first fixing block 3 and the second fixing block 6 are provided with corresponding locking holes 11, and expansion slots 12 are provided on both sides of the locking hole 11; both ends of the locking nail 13 are extended with locking blocks 14 in a direction perpendicular to its own axis, and the locking block 14 can pass through the expansion slot 12.

[0063] After the locking block 14 passes through the expansion slot 12, the knob locking nail 13 is turned to stagger the locking block 14 and the expansion slot 12, so that the first fixing block 3 and the second fixing block 6 can be locked relative to the locking nail 13 respectively, which is easy to operate and has a good anti-loosening effect.
