DETAILED DESCRIPTION

[0022] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0023] like Figure 1-9 As shown, the present invention provides a dry-type transformer in a wind turbine cabin, comprising a square steel 1, a dry-type transformer body 11 is fixedly installed on the top of the square steel 1, an L-shaped bracket 12 is fixedly installed on the side wall of the square steel 1, the bracket 12 is horizontally positioned and rotatably provided with two vertical driving screws 13 at one end away from the square steel 1, the top of the driving screw 13 is rotatably provided on the top of the bracket 12, a horizontally arranged moving plate 14 is commonly threadedly inserted between the two driving screws 13, a placing plate 15 is rotatably provided at one end of the moving plate 14 away from the screw 13, a plurality of fans 16 distributed at equal intervals are fixedly installed on the placing plate 15 and the fans 16 are arranged in an inclined manner, an L-shaped connecting plate 3 is fixedly provided on the lower surface of the moving plate 14, a driving assembly is provided on the connecting plate 3, and an auxiliary cooling assembly is installed at one end of the placing plate 15 away from the moving plate 14.

[0024] The auxiliary cooling assembly includes a cooling box 2, wherein cooling water is stored in the cooling box 2, a heat dissipation fin 21 is fixedly installed at the bottom of the cooling box 2, and the heat dissipation fin 21 is fixedly installed on the lower surface of the placement plate 15, a first delivery pipe 22 is installed on the heat dissipation fin 21, a first air pump 23 is installed at one end of the first delivery pipe 22, the output end of the first delivery pipe 22 away from the first air pump 23 is inserted through the cooling box 2, and a second delivery pipe 24 is connected to the cooling box 2, and the second delivery pipe 24 An end away from the first conveying pipe 22 is connected with an outlet pipe 27 having the same setting as the fan 16, and the outlet pipe 27 passes through the cooling box 2. An end of the placing plate 15 away from the screw rod 13 is fixedly installed with an air plate 26, and three air pipes 27 distributed at equal intervals are installed on the air plate 26. The air pipe 27 is provided with air holes distributed at equal intervals. One end of the second conveying pipe 24 passing through the cooling box 2 is fixedly connected and arranged in the air plate 26, and an end of the second conveying pipe 24 close to the placing plate 15 is fixedly installed with a second air pump 25.

[0025] By adopting the above technical solution, the first air pump 23 will work to suck the external gas into the first delivery pipe 22. At this time, the first delivery pipe 22 will also be cooled by the heat absorption of the heat dissipation fins 21, so that the temperature is stably reduced. Then, the reduced temperature will enter the second delivery pipe 24. Since the second delivery pipe 24 is arranged in the cooling box 2 and the cooling box 2 is filled with cooling water, the temperature of the air input into the second delivery pipe 24 will be reduced again. At this time, the cooled gas will pass through the second air pump 25 and the air plate 26 and will be ejected from the air pipe 27. Since the air pipe 27 is arranged near the fan 16, the fan 16 will make the ejected gas after cooling enter and exit near the surface of the dry-type transformer. The cooled gas will quickly neutralize the temperature of the surface of the dry-type transformer and cool it down.

[0026] The first delivery pipe 22 and the second delivery pipe 24 are both arranged in an S-shape.

[0027] By adopting the above technical solution, the first delivery pipe 22 and the second delivery pipe 24 can increase the duration of gas flow, thereby better improving the duration of gas cooling and heat dissipation.

[0028] One end of the top tube bracket 12 of the two screw rods 13 is connected through a first belt 17 , and a first motor 18 is fixedly installed on the top of the bracket 12 . The output end of the first motor 18 is coaxially fixed on one of the screw rods 13 .

[0029] By adopting the above technical solution, the first motor 18 cooperates with the first belt 17 to provide power to the two screw rods 13 at the same time, thereby improving the convenience of operation.

[0030] The driving assembly includes a connecting shaft 31, which is inserted through the moving plate 14, one end of the placing plate 15 is fixedly set on the connecting shaft 31, and a transmission shaft 33 arranged parallel to the connecting shaft 31 is provided on the connecting plate 3, and both ends of the transmission shaft 33 are connected to the connecting shaft 31 through a second belt 32 for transmission, and a driving gear 34 is fixedly provided at the middle end of the transmission shaft 33, and a tooth plate 35 is meshed at the bottom of the driving gear 34, and a driving plate 36 arranged in a cross distribution with the tooth plate 35 itself is fixedly provided at the bottom of the tooth plate 35, and a movable groove 37 is penetrated at the middle end of the driving plate 36, and one end of the movable groove 37 is fixedly provided with a push block 38, and a rotating plate 39 is fixedly provided at the bottom of the pushing block 38, and a vertically arranged rotating shaft 4 is fixedly provided at one end of the rotating plate 39 away from the pushing block 38, and the bottom of the rotating shaft 4 is rotatably inserted on the connecting plate 3.

[0031] By adopting the above technical solution, when the rotating shaft 4 rotates, it will drive the rotating plate 39 and the pushing block 38 to rotate. At this time, the rotating plate 39 will drive the pushing block 38 to continuously move from one end of the movable groove 37 on the driving plate 36 to the other end, so that the pushing block 38 can continuously move back and forth in the movable groove 37. At this time, the driven driving plate 36 will continuously move back and forth along the support rod 42, so that the repeatedly moving driving plate 36 will drive the toothed plate 35 fixed on the top to drive the driving gear 34 to continuously move back and forth. At this time, the driving gear 34 will drive the transmission shaft 33 to drive the connecting shaft 31 to rotate back and forth continuously through the second belts 32 at both ends. At this time, the rotating connecting shaft 31 will drive the placing plate 15 to swing. At this time, the placing plate 15 will take the connecting shaft 31 as the center and repeatedly swing back and forth with the connecting shaft 31. Therefore, when the screw rod 13 in the above step rotates, the fan 16 located on the placing plate 15 will repeatedly swing while repeatedly moving up and down.

[0032] A plurality of groups of vertical plates 6 are fixedly provided at one end of the connecting plate 3 away from the bracket 12. The number of vertical plates 6 in each group is two and they are symmetrically arranged. A rotating rod 61 is provided between two adjacent vertical plates 6 for common rotation. The rotating rod 61 is located between the two vertical plates 6 and is fixed with fan blades 62. The rotating rods 61 on the plurality of groups of vertical plates 6 are connected by a third belt 63. A transmission assembly is provided between the rotating rod 61 and the rotating shaft 4.

[0033] By adopting the above-mentioned technical solution, the multiple third belts 63 can simultaneously drive the multiple rotating rods 61 to rotate, so that the multiple groups of fan blades 62 rotate at the same time. The rotating fan blades 62 will face the heat dissipating fins 21, blow out the heat accumulated on the heat dissipating fins 21, and reduce the temperature of the heat dissipating fins 21, so that the first conveying pipe 22 can still effectively cool the inhaled gas.

[0034] Support rods 42 are movably inserted at two ends of the connecting plate 3 close to the driving plate 36 , and two ends of the support rods 42 are fixedly arranged on the connecting plate 3 .

[0035] By adopting the above technical solution, the support rod 42 can guide and support the driving plate 36.

[0036] A second motor 41 is fixedly disposed at the bottom of the connecting plate 3 near the rotating shaft 4 , and an output end of the second motor 41 is coaxially fixedly disposed on the rotating shaft 4 .

[0037] By adopting the above technical solution, the second motor 41 can provide sufficient power for the rotation of the rotating shaft 4, which is convenient for the staff to operate.

[0038] The transmission assembly includes a transmission shaft 5, which is rotatably arranged on the connecting plate 3 and close to the rotating shaft 4 in a vertical state. The transmission shaft 5 is connected to the rotating shaft 4 via two meshing gears, and the top of the transmission shaft 5 is connected to one of the rotating rods 61 via two meshing bevel gears 53.

[0039] By adopting the above technical solution, the rotating rod 61 on the fan blade 62 and the rotating shaft 4 can be rotated in conjunction with each other through the transmission shaft 5, thereby increasing the linkage of the device.

[0040] A large gear 52 is fixedly disposed on the rotating shaft 4 , and a small gear 51 meshing with the large gear 52 is fixedly disposed on the transmission shaft 5 .

[0041] By adopting the above technical solution, when the large gear 52 drives the small gear 51 to rotate, the small gear 51 can rotate faster, so that the transmission shaft 5 fixed on the small gear 51 drives the rotating rod 61 and the fan blades 62 to rotate faster, and the fan blades 62 rotate faster, so as to quickly cool down the heat dissipating fins 21 and the gas in the first delivery pipe 22.

[0042] When in use, the first motor 18 and the second motor 41 are started, and the first motor 18 cooperates with the first belt 17 to drive the two screw rods 13 to rotate at the same time. The rotating screw rod 13 will drive the movable plate 14 threadedly connected to itself to move up and down along the screw rod 13. At this time, the fan 16 arranged on the movable plate 14 and the placing plate 15 will move up, so as to blow and dissipate heat on the surface of the dry-type transformer body 11. When the first motor 18 is started forward and reversely, the fan 16 will be driven by the screw rod 13 to move up and down repeatedly, so as to effectively blow and dissipate heat on the upper and lower ends of the surface of the dry-type transformer body 11. During the starting process of the screw rod 13, the second motor 41 can drive the rotating shaft 4 to rotate. At this time, the rotating rotating shaft 4 will drive the rotating plate 39 fixed at the top to rotate, and the rotating rotating plate 39 will drive the push block 38 fixed at the end to move. Subsequently, when the push block 38 rotates with the rotating plate 39, the push block 38 will push the driving plate 36 to move along the support rod 42. As the rotating shaft 4 drives the rotating plate 39 to rotate continuously, the rotating plate 39 will drive the push block 38 to continuously move from one end of the movable groove 37 on the driving plate 36 to the other end, so that the push block 38 moves back and forth repeatedly in the movable groove 37. At this time, the driven driving plate 36 will continuously move back and forth along the support rod 42, thereby repeatedly moving the driving plate 36. 6. The toothed plate 35 fixedly arranged at the top of the drive drive drives the driving gear 34 to move back and forth repeatedly. At this time, the driving gear 34 drives the transmission shaft 33 to drive the connecting shaft 31 to rotate back and forth continuously through the second belts 32 at both ends. At this time, the rotating connecting shaft 31 drives the placing plate 15 to swing. At this time, the placing plate 15 will take the connecting shaft 31 as the center of the circle and swing back and forth repeatedly with the connecting shaft 31. Therefore, when the screw rod 13 in the above step rotates, the fan 16 located on the placing plate 15 will repeatedly swing while repeatedly moving up and down. At this time, during the movement, the range of blowing and cooling the surface of the dry-type transformer is increased, and the heat accumulated on the surface is efficiently cooled better and more comprehensively. When the fan 16 moves along with the rotation of the screw rod 13, the first air pump 23 will work to suck the external air into the first delivery pipe 22. At this time, the first delivery pipe 22 will also be cooled by the heat absorption of the heat dissipation fins 21, so that the temperature is stably reduced. Then, the reduced temperature will enter the second delivery pipe 24. Since the second delivery pipe 24 is arranged in the cooling box 2 and the cooling box 2 is filled with cooling water, the temperature of the air input into the second delivery pipe 24 will be reduced again. At this time, the cooled gas will pass through the second air pump 25 and the air plate 26 and will be ejected from the air pipe 27. Since the air pipe 27 is arranged near the fan 16, the fan 16 will make the ejected gas after cooling enter and exit the surface of the dry-type transformer. The cooled gas will quickly neutralize the temperature of the surface of the dry-type transformer to cool it down. At the same time, the fan 16 will blow off the hot air attached to its surface. Therefore, when the dry-type transformer is arranged in the cabin, the traditional natural gas outside the dry-type transformer is changed to the gas supplied by the fan 16, the air pipe 27, etc. The device composed of the components performs efficient heat dissipation treatment, and the heat dissipation effect is better, so that the heat dissipation effect of the surface of the dry-type transformer is improved when it is working, and its operation is more stable. When the above-mentioned heat dissipation fins 21 dissipate heat for the air inside the first conveying pipe 22, the multiple third belts 63 provided can simultaneously drive the multiple rotating rods 61 to rotate, so that the multiple sets of fan blades 62 rotate at the same time, and the rotating fan blades 62 will face the heat dissipation fins 21, blow out the heat accumulated on the heat dissipation fins 21, and reduce the temperature of the heat dissipation fins 21, so that the first conveying pipe 22 can still effectively cool the inhaled gas. At the same time, the rotating rod 61 and the rotating shaft 4 on the fan blade 62 can be linked to rotate through the transmission shaft 5, thereby increasing the linkage of the device, and the large gear 52 drives the small gear 51 to rotate, so that the small gear 51 rotates faster, so that the transmission shaft 5 fixed on the small gear 51 drives the rotating rod 61 and the fan blade 62 to rotate faster, so that the fan blade 62 rotates faster, and the heat dissipation fin 21 and the gas in the first conveying pipe 22 are quickly cooled.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
