Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a heat dissipation fan for transformers. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core (magnetic core). The main functions of a transformer are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. According to the purpose, it can be divided into: power transformer and special transformer.

[0003] An existing patent (publication number: CN218826537U) discloses a cooling fan for a transformer, which can dissipate heat for the transformer by starting the cooling fan main body. The dust-proof mechanism on one side of the cooling fan main body can reduce the suction of dust and garbage by the cooling fan main body. When the cooling fan main body needs to be disassembled and cleaned, it is only necessary to pull the pull rod to pull the side wall of the limit plate away from the limit groove, which makes it convenient for the staff to disassemble the cooling fan main body.

[0004] However, the above technical solution still has certain defects. The device can quickly disassemble the heat dissipation fan body for easy cleaning, but frequent cleaning of the fan body will cause damage to its internal components. It is only necessary to frequently clean the dust net and clean the fan body regularly, otherwise the service life of the fan body will be reduced. For this reason, a heat dissipation fan for a transformer is proposed. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0028] The following describes an embodiment of the utility model based on its overall structure.

[0029] A heat dissipation fan for a transformer, such as Figures 1 to 6 As shown, it includes a base plate 100, a transformer 110 is fixed to the top of the base plate 100 by bolts, a frame 120 is installed on the top of the base plate 100, through grooves are opened at both ends of the frame 120, and a mounting mechanism 200 is arranged in the through groove, and a dustproof mechanism 300 is opened at the top of the mounting mechanism 200;

[0030] The mounting mechanism 200 includes a shell 210 disposed in a through groove, with spring grooves 221 provided on both sides of the shell 210, a spring 220 being fixed to the inner wall of the spring groove 221, an insert block 230 being fixed to the other side of the spring 220, the insert block 230 being disposed in a slot 130 provided on the inner wall of the through groove, a push plate 240 being abutted and connected to the other side of the insert block 230, a first piston rod 241 being fixed to the other side of the push plate 240, a first piston plate 250 being fixed to the other end of the first piston rod 241, the first piston plate 250 being movably connected to the inner wall of the first piston box 140, a transmission pipe 260 being connected to one side of the first piston box 140, the other end of the transmission pipe 260 extending to the inner wall of the second piston box 150, a second piston plate 270 being provided on the inner wall of the second piston box 150 and being slidably connected thereto, the second piston plate 270 being connected to a rain shield 280 through a second piston rod, and a fan 400 being installed inside the shell 210.

[0031] By inserting the shell 210 into the through groove, the plug blocks 230 on both sides of the shell 210 will squeeze the spring 220 to make it enter the spring groove 221. When fully inserted, the spring 220 will squeeze the plug block 230 into the slot 130. The plug block 230 drives the first piston plate 250 through the abutment plate 240 and the first piston rod 241 to transmit the gas inside the first piston box 140 into the second piston box 150 through the transmission pipe 260. The second piston plate 270 inside the second piston box 150 drives the rain shield 280 to extend through the second piston rod, thereby protecting one side of the installation mechanism 200. Conversely, the rain shield 280 can be pushed to contact the limit position, so that the dustproof mechanism 300 does not need to frequently disassemble the fan 400, reducing the risk of damage to its internal components due to disassembly of the fan 400. The dustproof net is frequently cleaned and the fan body is cleaned regularly, thereby extending the service life of the fan body.

[0032] Please refer to Figures 1 to 4 The size of the spring groove 221 matches the size of the slot 130 and the size of the plug block 230. A round hole is provided on the surface of the first piston box 140, and the size of the round hole matches the size of the first piston rod 241. A slide groove 160 is provided on one side of the second piston box 150, and the slide groove 160 is slidably connected to the rain shield 280.

[0033] The spring groove 221 and the slot 130 allow the insert block 230 to move, the round hole on the surface of the first piston box 140 allows the first piston rod 241 to move, and the slide groove 160 allows the rain shield 280 to move.

[0034] Please refer to Figures 4 to 5 The dustproof mechanism 300 includes a dustproof groove 310 opened at the top of the shell 210, and a ball is provided on the inner wall of the dustproof groove 310. The ball inside the dustproof groove 310 is slidably connected with the dustproof net 320. A square groove 330 is opened on the front end surface of the shell 210, and a plurality of rotating pages 340 are provided on the inner wall of the square groove 330. The plurality of rotating pages 340 are distributed in a linear array.

[0035] When the dust net 320 needs to be replaced, turn off the fan 400. At this time, the rotating page 340 will be downward due to gravity. At this time, pull the dust net 320 to remove it from the dust slot 310. The rotating page 340 can isolate the surface dust to prevent dust from entering the fan 400 when the dust net 320 is replaced. When the fan 400 is started, it can drive the rotating page 340 to rotate, so as to ventilate and dissipate heat.

[0036] When in use, by inserting the shell 210 into the through groove, the plug blocks 230 on both sides of the shell 210 will squeeze the spring 220 to make it enter the spring groove 221. When fully inserted, the spring 220 will squeeze the plug block 230 into the slot 130. The plug block 230 drives the first piston plate 250 through the abutment plate 240 and the first piston rod 241 to transmit the gas inside the first piston box 140 into the second piston box 150 through the transmission pipe 260. The second piston plate 270 inside the second piston box 150 drives the rain shield 280 to extend through the second piston rod, thereby protecting one side of the installation mechanism 200. Conversely, the rain shield 280 can be pushed to contact the limit position, so that the dustproof mechanism 300 does not need to frequently disassemble the fan 400, reducing the risk of damage to its internal components due to disassembly of the fan 400. By frequently cleaning the dustproof net and regularly cleaning the fan body, the service life of the fan body is extended. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.
