Description

Technical Field

[0001] This utility model relates to the field of cooling fan technology, specifically a transformer cooling fan housing structure. Background Technology

[0002] Transformer cooling fans are a crucial component of transformer cooling systems, primarily used to improve the transformer's heat dissipation efficiency. Depending on the cooling method, transformer cooling systems can be categorized into several types, including oil-immersed self-cooling, oil-immersed air-cooling, and forced oil circulation air-cooling. In oil-immersed air-cooling systems, fans are installed near each radiator in the transformer tank. Forced convection enhances the radiator's heat dissipation capacity, thereby improving cooling efficiency. This cooling method can increase the transformer's output capacity by 20% to 40%. In some mountainous areas with limited installation conditions, a rectangular mounting platform is constructed using cement and bricks. The top of the platform closely matches the outline of the fan mounting base, and the fan is bolted in for overall fixation. However, mountainous areas rarely have tall buildings, and transformers are frequently exposed to direct sunlight. Furthermore, travel in mountainous areas is inconvenient. If the transformer overheats, personnel cannot arrive on-site immediately for adjustments. Currently, some transformer cooling fans are bolted to the top of the platform, providing only horizontal airflow for heat dissipation, which is inconvenient for temporary improvements in cooling efficiency and practically unusable.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Please see Figure 1-5 In this embodiment of the utility model, a transformer cooling fan housing structure includes a fan housing body 10, a connecting frame 11 fixedly connected to the outer wall of the fan housing body 10, a water spray plate 101 fixedly connected to the top of a rectangular plate 12, the rectangular plate 12 rotatably connected to the bottom of the connecting frame 11, an L-shaped frame 14 fixedly connected to each of the four corners of the rectangular plate 12, a limiting frame 13 slidably connected to the outside of the L-shaped frame 14, a driving module 15 disposed on the outer wall of the rectangular plate 12, the driving module 15 being used to drive the connecting frame 11 to reciprocate, and a limiting module 16 disposed outside the limiting frame 13, the limiting module 16 being used to limit the rectangular plate 12.

[0034] Specifically, a water spray plate 101 is fixed to the top of the rectangular plate 12. Water can be pumped into the water spray plate 101 through the rubber hose 102 and sprayed out. Water mist is sprayed out under the rotation of the fan blades. The hydraulic rod 131 is activated to drive the fan housing body 10 to move up and down. During the process, the fan housing body 10 swings back and forth to expand the spray range of the water mist. The water mist sprays the transformer fins, and the evaporation of water will accelerate the removal of heat, thereby temporarily improving the heat dissipation effect on the transformer. The setting of multiple limit brackets 13 makes the installation of the fan housing body 10 more convenient and easier to use.

[0035] Example 1

[0036] like Figure 1-4 As shown, in this embodiment, a slider 141 is fixedly connected to the outer wall of the L-shaped frame 14, and the slider 141 is slidably connected to the inner wall of the limiting frame 13. A hydraulic rod 131 is fixedly connected to the outer wall of the limiting frame 13, and the output end of the hydraulic rod 131 is fixedly connected to the adjacent L-shaped frame 14. The drive module 15 includes a control plate 151, which is fixedly connected to the rear side of the ball bearing 111. A circular plate 152 is rotatably connected to one side of the rectangular plate 12. A locking block 153 is rotatably connected to the top of the circular plate 152 and is movably locked inside the control plate 151. A hydraulic rod 131 is fixedly connected to the outer wall of one of the limiting frames 13. The rack 154 has a protective shell 155 fixedly connected to one side of an L-shaped frame 14. Inside the protective shell 155, shaft 156 and shaft 157 are rotatably connected. The top end of shaft 156 passes through the protective shell 155 and is fixedly connected to a circular plate 152. A bevel gear 1561 is fixedly sleeved at the bottom end of shaft 156. A bevel gear 1571 is fixedly sleeved on the outer wall of shaft 157. Bevel gear 1571 meshes with bevel gear 1561. A spur gear 1572 is fixedly sleeved at one end of shaft 157. The spur gear 1572 meshes with the rack 154.

[0037] In this embodiment, the sliding limit of the slider 141 is achieved by the limiting frame 13, thus limiting the sliding of the L-shaped frame 14 and preventing it from disengaging from the limiting frame 13. Simultaneously activating the two hydraulic rods 131 lifts multiple L-shaped frames 14, thereby lifting the rectangular plate 12 and the connecting frame 11 and fan housing 10 located thereon. Rotating the circular plate 152 causes the locking block 153 to rotate reciprocally. The locking block 153 then moves the guide control plate 151 to swing reciprocally, thereby driving the connecting frame 11 and fan housing 10 to move forward. The reciprocating oscillation of the head expands the spray range of the water mist, allowing the water mist to make more sufficient contact with the transformer fins. When the hydraulic rod 131 drives the L-shaped frame 14 to move upward as a whole, the transmission drive shaft 157 of the spur gear 1572 and rack 154 rotates, and the transmission drive shaft 156 of the bevel gear 1571 and bevel gear 1561 and the circular plate 152 rotate. Thus, during the up and down movement of the connecting frame 11, the fan housing body 10 is automatically driven to reciprocate and expand the range of water mist sprayed from the fan housing body 10 as a whole.

[0038] like Figure 5 As shown, in this embodiment, a rubber hose 102 is fixedly connected to the bottom of the water spray plate 101, and a plurality of ball bearings 111 are rotatably connected to the bottom of the connecting frame 11.

[0039] In practice, the rubber hose 102 is connected to the water supply pipeline, which can pump water into the spray plate 101 and spray water onto the fan housing 10 through the spray plate 101. As the fan blades rotate, water mist is sprayed out to spray water onto the transformer fins to accelerate heat dissipation. The ball bearings 111 support the connecting frame 11, making the connecting frame 11 rotate more smoothly.

[0040] Example 2

[0041] Based on Embodiment 1, in order to enable faster installation of the fan housing body 10.

[0042] like Figure 4 As shown, in this embodiment, the limiting module 16 includes a connecting plate 161, a limiting block 162 fixedly connected to one side of the connecting plate 161, the limiting block 162 slidably connected to the outer wall of the adjacent limiting frame 13, a spring 163 fixedly connected between the limiting block 162 and the limiting frame 13, and a fixing plate 164 fixedly connected to two adjacent connecting plates 161.

[0043] In practice, when installing the rectangular plate 12, the multiple limiting brackets 13 are aligned with the four corners of the cement platform body 20, and then the rectangular plate 12 is slowly lowered vertically. During the process, the two edges of the cement platform body 20 move the fixing plate 164, compressing the spring 163. Then the spring 163 resets and drives the fixing plate 164 to engage with the top of the rectangular groove 21. The rectangular plate 12 moves down until it contacts the top of the cement platform body 20, automatically completing the limiting, thereby quickly installing the fan housing body 10. After the hydraulic rod 131 is energized, it can self-lock to prevent the L-shaped bracket 14 from moving up on its own.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0045] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
