Description

Technical Field

[0001] This utility model relates to the field of wind power equipment technology, and more specifically, it relates to a heat dissipation device for wind power equipment. Background Technology

[0002] During the operation and maintenance of wind power equipment, the heat dissipation system is the core component to ensure the stable operation of electrical equipment. Wind power equipment is in a high-load working state for a long time, and core electrical components such as frequency converters, control cabinets, and transformers will generate a lot of heat. If heat dissipation is not timely, the equipment temperature will be too high, causing performance degradation, accelerated component aging, or even burnout failure, which will seriously affect power generation efficiency and equipment life.

[0003] As a key component for active cooling, the cooling fan requires regular maintenance and replacement. However, traditional wind turbine cooling devices use bolts or welding to install the cooling fan and protective net. This method of fixing requires special tools and fasteners during on-site maintenance, and the disassembly and assembly process is cumbersome and time-consuming. Especially when working in the narrow interior space of the wind turbine nacelle, operators need to repeatedly use wrenches or screwdrivers to tighten or loosen multiple fixing points, resulting in high labor intensity and low efficiency. A single cooling fan replacement often takes tens of minutes or even longer. In high-altitude working environments, there are also risks of tools falling and personnel safety hazards. For special environments such as offshore wind power and high-altitude wind power, severe weather conditions further increase the difficulty of maintenance and safety risks. The inefficiency of traditional fixing methods seriously restricts the rapid maintenance capability of wind turbine equipment, prolongs equipment downtime, and directly affects power generation and economic benefits.

The fixing sleeve 6 is plugged into the top of the plug rod 5. The outer wall of the fixing sleeve 6 has multiple mounting grooves 7, each with a damping shaft 8 connected to its inner side. The outer wall of the 8 is rotatably connected with a locking block 9. The outer wall of the insertion rod 5 is provided with a locking groove 10.

The outer wall of the limiting sleeve 11 is provided with a limiting groove 12. The outer wall of the fixed sleeve 6 is rotatably provided with a rotating sleeve 13. The bottom surface of the rotating sleeve 13 is fixedly provided with a sliding rod 14. Multiple sets of sliding rods 14 are provided, and the bottom end and the outer wall are fixedly provided with limiting blocks 15. Multiple sets of limiting blocks 15 abut against both sides of the limiting sleeve 11. The outer wall of the equipment box 1 is provided with a vent hole 16.

[0022] The outer wall of the mounting bracket 2 has a socket 17, and the plug rod 5 is inserted into the socket 17.

[0023] The inner side of multiple sets of card blocks 9 and the top of the insertion rod 5 are all provided with bevels. The bottom surfaces of multiple sets of card blocks 9 are all set to be arc-shaped and are slidably connected to multiple sets of mounting slots 7 respectively.

[0024] A guide block 18 is fixedly provided on the inner side of the limiting sleeve 11, and a guide groove 19 is provided on the outer wall of the fixing sleeve 6. Multiple sets of guide blocks 18 and guide grooves 19 are provided and are slidably connected.

[0025] Each of the multiple limiting grooves 12 has an unlocking hole 20 at one end.

[0026] A tension spring 21 is connected to the top surface of the limiting sleeve 11, and a thrust bearing 22 is connected between the top of the tension spring 21 and the rotating sleeve 13.

[0027] A mounting plate 23 is fixedly provided on the top surface of the rotating sleeve 13. A slider 24 is fixedly provided on the top of the mounting plate 23.

[0028] In this embodiment, when the cooling fan 3 needs to be installed, the insertion hole 17 is inserted into the insertion rod 5, and the protective net 4 is inserted into the insertion rod 5. The fixing sleeve 6 is inserted into the top of the insertion rod 5 so that its bottom surface abuts against the top surface of the protective net 4. The insertion rod 5 is pushed by the top of the insertion rod 5 to rotate along the damping shaft 8 to make room for the insertion rod 5. Then, the sliding limit sleeve 11 stretches the tension spring 21. The limit sleeve 11 pushes the multiple sets of locking blocks 9 to engage in the slot 10. At this time, the slide rod 14 is in the unlocking hole 20. The rotating sleeve 13 drives the multiple sets of slide rods 14 to slide into the limit groove 12, so that the multiple sets of limit blocks 15 abut against the two sides of the limit sleeve 11 respectively. At this time, the multiple sets of push springs 26 push the positioning block 25 to abut against the positioning groove to position the rotating sleeve 13, thus completing the quick installation of the cooling fan 3 and the protective net 4.

[0029] More specifically, when the cooling fan 3 needs to be disassembled, rotating the rotating sleeve 13 drives multiple sets of sliders 24 to slide within the positioning sleeve 27. Through the positioning hole 28, the positioning block 25 is pushed to compress the push spring 26, causing multiple sets of positioning blocks 25 to move continuously between multiple sets of positioning slots. The rotating sleeve 13 drives multiple sets of sliding rods 14 to slide into the unlocking hole 20, releasing the restriction on the limiting sleeve 11. The tension spring 21 pulls the limiting sleeve 11 to release the base frame of multiple sets of locking blocks 9. Then, the fixing sleeve 6 and the insertion rod 5 can be separated to release the contact with the protective net 4. Then, the protective net 4 and the cooling fan 3 can be disassembled.

[0030] In summary, when using or operating the entire device: when installing the cooling fan 3, insert the plug 17 into the plug rod 5, and insert the protective net 4 into the plug rod 5. Insert the fixing sleeve 6 into the top of the plug rod 5 so that its bottom surface abuts against the top surface of the protective net 4. Push the top of the plug rod 5 to rotate the multiple sets of locking blocks 9 along the damping shaft 8 to make room for the plug rod 5. Then, the sliding limit sleeve 11 stretches the tension spring 21. The limit sleeve 11 pushes the multiple sets of locking blocks 9 to engage in the slot 10. At this time, the slide rod 14 is in the unlocking hole 20. Rotate the rotating sleeve 13 to drive the multiple sets of slide rods 14 to slide into the limit groove 12, so that the multiple sets of limit blocks 15 abut against both sides of the limit sleeve 11. At this time, the multiple sets of push springs 26 push the positioning block 25 to abut against the positioning groove to position the rotating sleeve 13, thus completing the quick installation of the cooling fan 3 and the protective net 4.

[0031] When the cooling fan 3 needs to be disassembled, rotating the rotating sleeve 13 drives multiple sets of sliders 24 to slide within the positioning sleeve 27. Through the positioning hole 28, the positioning block 25 is pushed to compress the push spring 26, causing multiple sets of positioning blocks 25 to move continuously between multiple sets of positioning slots. The rotating sleeve 13 drives multiple sets of sliding rods 14 to slide into the unlocking hole 20, releasing the restriction on the limiting sleeve 11. The tension spring 21 pulls the limiting sleeve 11 to release the base frame of multiple sets of locking blocks 9. Then the fixing sleeve 6 can be separated from the insertion rod 5 to release the contact with the protective net 4. Then the protective net 4 and the cooling fan 3 can be disassembled.
