[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. Its main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc. The transformer will generate heat during use. If the temperature inside the device is too high, it will cause electric sparks and short circuits, thus causing safety hazards such as fire.

DETAILED DESCRIPTION

[0023] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The utility model provides a technical solution: a substation main transformer cooling device with a descaling structure, comprising a shell 1 for installing the transformer, an air inlet hole 2 is opened on one side of the shell 1, and an air outlet hole 3 is opened on the upper surface of the shell 1, and an air inlet channel 7 is detachably connected to one side of the air inlet hole 2 of the shell 1, and a heat dissipation unit 16 is installed at one end of the air inlet channel 7 close to the air inlet hole 2, and a positioning plate 9 is arranged at the air inlet end of the air inlet channel 7, and a card slot 10 is opened on one side of the positioning plate 9, and a dustproof mesh plate 13 is inserted in the card slot 10; through the cooperation between the air inlet channel, the dustproof mesh plate and the descaling mechanism, the driving bevel gear is driven by the motor to mesh with the driven bevel gear through the rotating shaft, and the screw converts the rotation into a moving plate that moves linearly along the guide rod, so as to facilitate the cleaning plate brush to remove the dust accumulated on the dustproof mesh plate, so as to prevent dust from entering the shell and affecting the operation of the transformer, and at the same time, it is convenient to keep the cleanliness of the dustproof mesh plate, so as to ensure the ventilation effect and improve the heat dissipation efficiency.

[0025] The descaling mechanism 17 includes a motor 171, a screw 174 and a movable plate 176. The output shaft of the motor 171 is drivingly connected to a rotating shaft 172 that passes through the positioning plate 9. A driven bevel gear 175 is arranged on the outer side of one end of the screw 174. One end of the rotating shaft 172 is fixedly connected to a driving bevel gear 173 that meshes with the driven bevel gear 175. The movable plate 176 is threadedly connected to the other end of the screw 174. A plurality of connecting bolts 177 are inserted on one side of the movable plate 176. A cleaning brush 178 that conflicts with the dustproof screen plate 13 is detachably connected to the other side of the movable plate 176 through a plurality of connecting bolts 177.

[0026] The screw 174 is rotatably connected to both sides of the inner cavity of the air inlet channel 7, and a baffle 11 for rotationally connecting the screw 174 is fixedly connected to one side of the positioning plate 9. A guide rod 179 is inserted into one side of the baffle 11, and a circular hole slidably connected to the guide rod 179 is opened on one side of the movable plate 176. The moving range of the movable plate 176 is limited by the baffle 11, thereby increasing the service life of the descaling mechanism 17 and preventing the movable plate 176 from contacting the driven bevel gear 175.

[0027] The guide rod 179 is arranged directly below the screw rod 174. The motor 171 is installed at the top of the inner cavity of the air inlet channel 7. The motor 171 is arranged between the positioning plate 9 and the heat dissipation unit 16. The stability of the horizontal movement of the moving plate 176 is improved through the guide rod 179, and the cleaning brush 178 can evenly sweep the dust on the dust-proof net plate 13.

[0028] On one side of the air inlet channel 7, there is a side hole 8 for inserting the dust-proof net plate 13. On the side of the dust-proof net plate 13 opposite to the positioning plate 9, there is a buckle plate 14 fixedly connected. On one side of the buckle plate 14, there are two groups of locking bolts 15 threadedly connected to the air inlet channel 7. The installation of the dust-proof net plate 13 is facilitated through the side hole 8, and at the same time, the dust-proof net plate 13 is conveniently fixed through the locking bolts 15, improving the stability of the installation of the dust-proof net plate 13 and also facilitating the disassembly and replacement of the dust-proof net plate 13, improving the convenience.

[0029] The cross-section of the dust-proof net plate 13 is smaller than that of the air inlet channel 7. The vertical cross-section of the positioning plate 9 is arranged in a U-shape. On the lower surface of the air inlet channel 7, there is a dirt falling groove 12. Through the dirt falling groove 12, it is convenient to discharge the dust cleared by the cleaning brush 178 out of the air inlet channel 7, avoiding the accumulation of dust in the air inlet channel 7 and affecting the ventilation effect.

[0030] At the bottom of the inner cavity of the housing 1, there is a detachable heat dissipation base 19. On the upper surface of the heat dissipation base 19, there is a transformer body 21 installed. On one side of the heat dissipation base 19, there are multiple ventilation holes 20. On the lower surface of the housing 1, there is a support leg 18 fixedly connected. Through the heat dissipation base, it is convenient to export the heat generated by the transformer body 21, and then the heat is exported through the air circulation in the ventilation holes 20, improving the heat dissipation efficiency.

[0031] On the upper surface of the housing 1, there is an air outlet channel 4 communicated with the air outlet hole 3. At the upper end of the air outlet channel 4, there are multiple columns 6 fixedly connected. At the upper ends of the multiple columns 6, there is a rain shelter 5 fixedly connected. Through the multiple columns 6, the stability of the installation of the rain shelter 5 on the air outlet channel 4 is improved, ensuring the ventilation effect of the housing 1 and at the same time preventing rainwater from entering the housing 1.

[0032] The cross-section of the rain shelter 5 is larger than that of the air outlet hole 3. The horizontal plane height of the open end of the rain shelter 5 is lower than the horizontal plane height of the upper end of the air outlet channel 4. On one side of the housing 1 opposite to the air inlet hole 2, there is a maintenance door. Through the rain shelter 5 and the air outlet channel 4, it is avoided that water seeps into the housing 1 through the gap between the rain shelter 5 and the air outlet channel 4, improving the waterproof effect of the housing 1 and preventing the transformer body 21 from being eroded by rainwater.

[0033] When in use, the heat dissipation unit 16 supplies air to the inside of the shell 1, so that the outside air enters the shell 1 after filtering out dust through the dustproof screen plate 13, and the air after air cooling and heat dissipation of the transformer body 21 is discharged through the air outlet 3. After long-term ventilation and heat dissipation, a lot of dust will accumulate on the dustproof screen plate 13, affecting the ventilation effect. The control motor 171 drives the rotating shaft 172 to rotate, and the rotating shaft 172 engages the driven bevel gear 175 through the driving bevel gear 173. The driven bevel gear 175 drives the screw 174 to rotate, and the screw 174 drives the moving plate 176 to move along the guide rod 179, so that the cleaning plate brush 178 on the moving plate 176 brushes off the dust docked on the dustproof screen plate 13, and the docked dust is discharged from the air inlet channel 7 through the scale removal groove 12, thereby ensuring the ventilation efficiency of the dustproof screen plate 13, avoiding the influence of dust accumulation on ventilation, and improving the heat dissipation effect.

[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
