[0031] Reference Figure 1 and Figure 2 As shown, the utility model provides a technical solution: an oil-immersed transformer with a sound insulation structure, comprising a transformer body 1, a placement plate 2 is installed on the lower surface of the transformer body 1, and a blocking device 3 is provided on the side of the placement plate 2 close to the transformer body 1. By setting the blocking device 3, the effect of blocking and absorbing the noise generated by the transformer body 1 during operation is achieved, thereby avoiding the transformer body 1 from generating a large volume when working, and the excessive sound forming noise, which leads to noise pollution, thereby improving the practicality of the device. A dustproof device 4 is provided on the surface of the soundproof frame 301. By setting the dustproof device 4, the effect of dustproofing the transformer body 1 is achieved, thereby avoiding the transformer body 1 from being used outdoors for a long time, and dust entering the surface of the transformer body 1, resulting in a large amount of dust covering the surface of the transformer body 1, thereby affecting the heat dissipation of the transformer body 1, thereby improving the protectiveness of the device.

[0032] The specific arrangement and function of the blocking device 3 and the dustproof device 4 will be described in detail below.

[0033] Reference Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment: the barrier device 3 includes a soundproof frame 301, the soundproof frame 301 is fixedly connected to the side of the placement plate 2 close to the transformer body 1, two sound-absorbing panels 302 are slidably inserted in the soundproof frame 301, and the sides of the two sound-absorbing panels 302 away from each other are fixedly connected with an operating block 303, both sides of the soundproof frame 301 are fixedly connected with a fixing rod 304, the arc surface of the fixing rod 304 is slidably connected with an operating plate 305, and the side of the operating plate 305 close to the soundproof frame 301 is fixedly connected with an insertion rod 306, and a slot is provided on the surface of the sound-absorbing panel 302. 04 One end away from the sound-absorbing frame 301 is fixedly connected to the limit plate 307, and the size of the plug rod 306 is adapted to the size of the slot of the sound-absorbing plate 302. When the staff pulls the operating panel 305, the operating panel 305 slides on the arc surface of the fixed rod 304. At this time, the limit plate 307 has the effect of limiting the maximum sliding distance of the operating panel 305 on the fixed rod 304, thereby preventing the operating panel 305 from detaching from the arc surface of the fixed rod 304 due to excessive pulling force when the staff pulls the operating panel 305. The arc surface of the fixed rod 304 is sleeved with a first spring 308, the two ends of the first spring 308 are fixedly connected to the operating plate 305 and the sound-proof frame 301 respectively. When the staff releases the operating plate 305, the resilience of the first spring 308 drives the operating plate 305 to slide on the arc surface of the fixed rod 304, and at the same time, the operating plate 305 drives the insertion rod 306 to move until the insertion rod 306 is inserted into the slot of the sound-absorbing plate 302. At this time, the first spring 308 improves the stability of the insertion rod 306 when limiting the sound-absorbing plate 302. Both sides of the sound-proof frame 301 are fixedly connected with screws 309, and the arc surface of the screw 309 is threaded with a sound-proofing screw. When the staff releases the limit of the plug rod 306 on the sound absorbing panel 302, they continue to pull the operating panel 305 to make the operating panel 305 slide on the arc surface of the fixed rod 304 until the operating panel 305 moves to the highest point of the fixed rod 304. At this time, the blocking plate 310 is rotated to make the blocking plate 310 threaded on the arc surface of the screw rod 309 until the blocking plate 310 moves to the bottom of the operating plate 305. At this time, the blocking plate 310 has achieved the effect of limiting the movement of the operating plate 305, so that the staff can pull out and replace the sound absorbing panel 302 more quickly.

[0034] Reference Figure 5 , Figure 6 and Figure 7As shown, specifically, the dustproof device 4 includes an L-shaped plate 41, which is fixedly connected to the surface of the sound-proof frame 301, and a driving rod 42 is inserted into the internal thread of the L-shaped plate 41. One end of the driving rod 42 is rotatably connected to a connecting block 43. A U-shaped frame 45 is fixedly connected to the side of the sound-proof frame 301 away from the L-shaped plate 41, and a rotating rod 46 is fixedly connected to the inner surface of the U-shaped frame 45. The arc surface of the rotating rod 46 is rotatably connected to a connecting plate 47, and a dustproof plate 48 is fixedly connected to one side of the connecting plate 47. The connecting block 43 is against one side of the dustproof plate 48, and a positioning rod 44 is fixedly connected to the side of the connecting block 43 close to the driving rod 42. The arc surface of the positioning rod 44 is slidably connected to the L-shaped plate 41. When the staff rotates the driving rod 42, the driving rod 42 rotates on the internal thread of the L-shaped plate 41, and the driving rod 42 drives the connecting block 43 to move, and the connecting block 43 drives the positioning rod 44 to slide in the L-shaped plate 41. At this time, the positioning rod 44 achieves the effect of limiting the connection block 43 from rotating with the driving rod 42, so as to improve the stability of the connection block 43 when it abuts against the dustproof plate 48. The arc surface of the rotating rod 46 is covered with two torsion springs 49, and the two ends of the torsion spring 49 are respectively fixedly connected to the U-shaped frame 45 and the connecting plate 47. When the staff releases the abutment of the connecting block 43 against the dustproof plate 48, the torsion force of the torsion spring 49 drives the connecting plate 47 to rotate on the arc surface of the rotating rod 46. At the same time, the connecting plate 47 drives the dustproof plate 48 to move until the dustproof plate 48 is fully opened. At this time, the effect of automatically opening the dustproof plate 48 is achieved, so as to reduce the operating steps of the staff on the device and improve the work efficiency of the staff.

[0035] Working principle: when the staff needs to block and absorb the noise emitted by the transformer body 1, pull the operating plate 305 to make the operating plate 305 slide on the arc surface of the fixed rod 304, the first spring 308 is stretched, and the operating plate 305 drives the insertion rod 306 to move until the insertion rod 306 no longer blocks the movement of the sound-absorbing plate 302. At this time, continue to pull the operating plate 305 to make the operating plate 305 slide on the arc surface of the fixed rod 304 until the operating plate 305 moves to the highest point of the fixed rod 304. At this time, rotate the blocking plate 310 to make the blocking plate 310 move on the arc surface of the screw rod 309 until the blocking plate 310 moves to the bottom of the operating plate 305. At this time, push the operating block 303, and the operating block 303 drives the sound-absorbing plate 302 is inserted into the sound-absorbing frame 301 until the sound-absorbing plate 302 moves to a suitable position. At this time, the blocking plate 310 is rotated again to make the blocking plate 310 move on the arc surface of the screw rod 309 until the blocking plate 310 is disengaged from the bottom of the operating plate 305. At this time, the resilience of the first spring 308 drives the operating plate 305 to slide on the arc surface of the fixing rod 304, and at the same time, the operating plate 305 drives the insertion rod 306 to move until the insertion rod 306 is inserted into the slot of the sound-absorbing plate 302. At this time, the effect of blocking and absorbing the noise generated by the working of the transformer body 1 is achieved, thereby avoiding the high volume generated by the transformer body 1 during operation, the excessive sound forming noise, and causing noise pollution, thereby improving the practicability of the device.

[0036] When the staff needs to perform dust prevention on the transformer body 1, they press the dust prevention plate 48, and the dust prevention plate 48 drives the connecting plate 47 to rotate on the arc surface of the rotating rod 46 until the dust prevention plate 48 is in contact with the upper surface of the sound-proof frame 301. At this time, the driving rod 42 is rotated to rotate the driving rod 42 in the L-shaped plate 41 internal thread. At the same time, the driving rod 42 drives the connecting block 43 to move, and the connecting block 43 drives the positioning rod 44 to slide in the L-shaped plate 41 until the connecting block 43 is in contact with the dust prevention plate 48. At this time, the effect of dust prevention on the transformer body 1 is achieved, and the transformer body 1 is prevented from being used outdoors for a long time, and dust enters the surface of the transformer body 1, resulting in a large amount of dust covering the surface of the transformer body 1, thereby affecting the heat dissipation of the transformer body 1, thereby improving the protection of the device.
