[0009] Furthermore, an activity mechanism is arranged on the reciprocating screw rod. The activity mechanism includes a movable plate threadedly sleeved on the reciprocating screw rod.

[0013] The present invention has the following beneficial effects: (1) For the three-dimensional wound iron core oil-immersed transformer with an intelligent temperature control function in the present invention, when the oil enters the loop box from the C-shaped groove, the oil will first enter the filter box under the guiding action of the L-shaped plate in cooperation with the inlet pipe. Under the action of pressure, the oil will enter the outer wall of the L-shaped plate through the L-shaped filter plate and the loop pipe and then return to the loop box again. At this time, when the oil passes through the L-shaped filter plate, the oxides and metal particles in the oil will be filtered on the L-shaped collection drawer in the filter box. The L-shaped collection drawer can be taken out regularly to clean the oxides and metal impurities, ensuring that the oxides and metal particles will not enter the variable voltage oil tank again, effectively avoiding the increase of the conductivity of the oil by the oxides to prevent danger, and at the same time preventing the metal particles from weakening the fluidity of the oil to avoid blockage; (2) For a three-dimensional wound core oil-immersed transformer with an intelligent temperature control function according to the present invention, when the driving motor is started, the driving motor drives the reciprocating screw to rotate. The reciprocating screw drives the movable plate to move up and down reciprocally. The movable plate drives the movable frame to move up and down reciprocally. When the movable frame descends, it drives the extrusion rod to descend. The extrusion rod drives the rectangular extrusion plate to descend. The rectangular extrusion plate extrudes the oil in the transformer tank. At this time, under the action of the oil pressure, the oil will push the rectangular adaptor plate upward through the round groove, making the rectangular adaptor plate closely adhere to the top inner wall of the adaption groove. At this time, the rectangular adaptor plate also blocks the gap where the adaption groove communicates with the two rectangular grooves. At this time, the oil will not flow above the rectangular extrusion plate through the rectangular extrusion plate and will only be subjected to the downward pressure of the rectangular extrusion plate. As the oil pressure below the rectangular extrusion plate becomes greater and greater, the oil will push several U-shaped groove oil inlet blocks to move towards the inner wall of the transformer tank. At this time, the inlet spring undergoes a compressive deformation. When the oil inlet holes on the U-shaped groove oil inlet blocks enter the oil inlet tank, the oil will enter the oil inlet tank through several oil inlet holes. Then, as the pressure increases, the oil will enter the U-shaped grooves in the heat dissipation plate and flow upward along the U-shaped grooves. At this time, when the reciprocating screw rotates, it drives several heat dissipation fan blades to rotate. The wind generated by the heat dissipation fan blades will enter the heat dissipation air hood through the air outlet pipe. The wind blows out along the heat dissipation air hood to dissipate heat from the surface of the heat dissipation plate. The oil entering the U-shaped grooves increases the surface area of the oil in contact with the heat dissipation plate, and the wind generated by the heat dissipation fan blades can achieve an effective heat dissipation effect; (3) For a three-dimensional wound core oil-immersed transformer with an intelligent temperature control function according to the present invention, the filtered oil will enter the oil outlet tank through the return tank. Under the action of the pressure, the oil will push the U-shaped groove oil outlet block to move away from the inner wall of the transformer tank. At this time, the outlet spring undergoes a tensile deformation. When the oil outlet holes on the U-shaped groove oil outlet block leave the oil outlet tank, the oil will flow out again through the oil outlet holes and enter the transformer tank. When the movable plate ascends, the corresponding extrusion rod also drives the rectangular extrusion plate to ascend. At this time, the rectangular extrusion plate drives the rectangular adaptor plate in the adaption groove to ascend. The oil will enter the rectangular groove through several oil leakage holes. Under the action of inertia, the rectangular adaptor plate will descend and leave the gap where the adaption groove communicates with the rectangular groove. Then, the oil will enter the adaption groove from the rectangular groove and above the rectangular adaptor plate. The oil will pass through the through holes and round grooves on the rectangular adaptor plate as the rectangular extrusion plate ascends. When the rectangular extrusion plate ascends, it drives some oil to ascend. At this time, the ascending oil will push the U-shaped groove oil outlet block to move towards the inner wall of the transformer tank. At this time, the oil outlet holes will enter the oil outlet tank, effectively avoiding the phenomenon of oil backflow above the rectangular extrusion plate, and at the same time preventing oxides and metal particles on the L-shaped collection drawer from flowing back into the U-shaped grooves again to cause blockage; (4) The present invention provides a three-dimensional wound iron core oil-immersed transformer with intelligent temperature control function. During the continuous up-and-down reciprocating motion of the movable plate, the oil in the transformer oil tank will continuously circulate and dissipate heat. When the oil temperature in the transformer oil tank is too high, the speed of the drive motor will also increase, thereby enhancing the heat dissipation effect and realizing intelligent temperature control. During the up-and-down reciprocating motion of the movable plate, the corresponding movable frame will drive the rectangular hollow frame to move, and the rectangular hollow frame will drive a number of cleaning plates to clean the dust and impurities adhered to the surfaces of a number of heat dissipation plates to prevent the heat dissipation effect of the heat dissipation plates from being affected by excessive dust. The dust scraped off by the cleaning plates will be blown away by the wind blown out by the heat dissipation hood to prevent the dust from falling into the heat dissipation hood.

[0020] As Figure 4 shown, a number of oil outlet mechanisms 2 are arranged in the transformer oil tank 1. The oil outlet mechanism 2 includes an oil outlet tank 201 fixedly installed on the inner wall of the transformer oil tank 1. The oil outlet tank 201 is communicated with the circuit box 104. A number of oil outlet springs 202 are fixedly installed on the left inner wall of the oil outlet tank 201. A U-shaped groove oil outlet block 203 is fixedly installed on the right side of a number of oil outlet springs 202. The right side of the U-shaped groove oil outlet block 203 extends outside the oil outlet tank 201. A number of oil outlet holes 204 are respectively opened at the top and bottom of the U-shaped groove oil outlet block 203.

[0021] The filtered oil will enter the oil outlet tank 201 through the circuit box 104. Under the action of pressure, the oil will push the U-shaped groove oil outlet block 203 to move in a direction away from the inner wall of the transformer oil tank 1. At this time, the oil outlet spring 202 undergoes a tensile deformation. When the oil outlet holes 204 on the U-shaped groove oil outlet block 203 leave the oil outlet tank 201, the oil will flow out from the oil outlet holes 204 again and enter the transformer oil tank 1.

[0022] As Figure 5 shown, a number of oil inlet mechanisms 3 are arranged in the transformer oil tank 1. The oil inlet mechanism 3 includes an oil inlet tank 301 fixedly installed in the transformer oil tank 1. The bottom of the oil inlet tank 301 is fixedly connected to the bottom inner wall of the transformer oil tank 1. A number of oil inlet springs 302 are fixedly installed on the left inner wall of the oil inlet tank 301. The right ends of a number of oil inlet springs 302 are fixedly installed with a U-shaped groove oil inlet block 303. The right side of the U-shaped groove oil inlet block 303 extends outside the oil inlet tank 301. A number of oil inlet holes 304 are opened at the top and bottom of the U-shaped groove oil inlet block 303.

[0023] The oil will push a number of U-shaped groove oil inlet blocks 303 to move in a direction close to the inner wall of the transformer oil tank 1. At this time, the oil inlet spring 302 undergoes a compressive deformation. When the oil inlet holes 304 on the U-shaped groove oil inlet block 303 enter the oil inlet tank 301, the oil will enter the oil inlet tank 301 from a number of oil inlet holes 304, and then the oil will enter the U-shaped groove 103 in the heat dissipation plate 102 as the pressure increases.

[0024] As Figure 6 and Figure 7 As shown in the figure, a heat dissipation mechanism 4 is provided at the bottom of the transformer oil tank 1. The heat dissipation mechanism 4 includes a heat dissipation box 401 fixedly installed at the bottom of the transformer oil tank 1. A driving motor 402 is fixedly installed at the bottom of the transformer oil tank 1. A reciprocating screw 403 is fixedly installed on the output shaft of the driving motor 402. The reciprocating screw 403 penetrates through the heat dissipation box 401 and is rotatably connected to the heat dissipation box 401. A plurality of heat dissipation fan blades 404 are fixedly installed on the reciprocating screw 403. A plurality of air outlet pipes 405 are fixedly installed at the top of the heat dissipation box 401. Heat dissipation air hoods 406 are fixedly installed at the mutually remote ends of the plurality of air outlet pipes 405. One side of the plurality of heat dissipation air hoods 406 close to each other is fixedly connected to the transformer oil tank 1.

[0025] It flows upward along the U-shaped groove 103. At this time, when the reciprocating screw 403 rotates, it will drive a plurality of heat dissipation fan blades 404 to rotate. The wind generated by the heat dissipation fan blades 404 will enter the heat dissipation air hood 406 from the air outlet pipe 405, and the wind blows out along the heat dissipation air hood 406 to dissipate heat from the surface of the heat dissipation plate 102. The oil entering the U-shaped groove 103 increases the surface area of the oil in contact with the heat dissipation plate 102, and the wind generated by the heat dissipation fan blades 404 can achieve an effective heat dissipation effect.

[0026] As Figure 7 shown in the figure, an activity mechanism 5 is provided on the reciprocating screw 403. The activity mechanism 5 includes a movable plate 501 threadedly sleeved on the reciprocating screw 403. A mounting plate 502 is rotatably installed at the bottom of the reciprocating screw 403. Two limiting rods 503 are fixedly installed at the top of the mounting plate 502. The two limiting rods 503 penetrate through the movable plate 501 and are both slidably connected to the movable plate 501. The top ends of the two movable plates 501 are fixedly connected to the transformer oil tank 1.

[0027] During the up-and-down movement of the movable plate 501, the limiting rod 503 will play a role in limiting the movable plate 501. In addition, the limiting rod 503 will also play a corresponding supporting role for the transformer oil tank 1.

[0028] As Figure 7 shown in the figure, a cleaning mechanism 6 is provided on the movable plate 501. The cleaning mechanism 6 includes a movable frame 601 fixedly installed on the movable plate 501. A rectangular hollow frame 602 is fixedly installed on the inner wall of the movable frame 601. A plurality of cleaning plates 603 are fixedly installed on the inner walls around the rectangular hollow frame 602. The plurality of cleaning plates 603 are all in contact with the plurality of heat dissipation plates 102.

[0029] During the reciprocating movement of the movable plate 501 up and down, the corresponding movable frame 601 will drive the rectangular hollow frame 602 to move. The rectangular hollow frame 602 will drive a plurality of cleaning plates 603 to clean the dust and impurities adhering to the surfaces of a plurality of heat dissipation plates 102, so as to avoid the influence of excessive dust on the heat dissipation effect of the heat dissipation plates 102. The dust scraped off by the cleaning plates 603 will be blown away by the wind blown out by the heat dissipation air hood 406, preventing the dust from falling into the heat dissipation air hood 406.

[0030] As Figure 8 shown, a pressing mechanism 7 is provided at the bottom of the movable frame 601. The pressing mechanism 7 includes a pressing rod 701 fixedly installed at the bottom of the movable frame 601. The bottom end of the pressing rod 701 extends into the variable pressure oil tank 1 and is slidably connected to the variable pressure oil tank 1. A rectangular pressing plate 702 is fixedly installed at the bottom end of the pressing rod 701. A plurality of winding cores 101 penetrate through the rectangular pressing plate 702 and are slidably connected to the rectangular pressing plate 702. Two rectangular grooves 703 are formed in the rectangular pressing plate 702. A plurality of oil leakage holes 704 are formed at the top of the rectangular pressing plate 702. The plurality of oil leakage holes 704 communicate with the two rectangular grooves 703.

[0031] During the upward movement of the rectangular pressing plate 702, it will drive some oil to rise. At this time, the rising oil will push the U-shaped groove oil outlet block 203 to move towards the inner wall of the variable pressure oil tank 1. At this time, the oil outlet hole 204 will enter the oil outlet tank 201, effectively avoiding the backflow of the oil above the rectangular pressing plate 702, and at the same time preventing the oxides and metal particles on the L-shaped collection drawer 109 from flowing back into the U-shaped groove 103 again to cause blockage.

[0032] As Figure 8 shown, an adaptation mechanism 8 is provided in the rectangular pressing plate 702. The adaptation mechanism 8 includes an adaptation groove 801 formed in the rectangular pressing plate 702. A rectangular adaptation plate 802 is slidably installed in the adaptation groove 801. A plurality of through holes are formed in the rectangular adaptation plate 802. The adaptation groove 801 communicates with the two rectangular grooves 703. A circular groove 803 is formed on the bottom inner wall of the adaptation groove 801.

[0033] The rectangular pressing plate 702 drives the rectangular adaptation plate 802 in the adaptation groove 801 to rise. The oil will enter the rectangular groove 703 from a plurality of oil leakage holes 704. Under the action of inertia, the rectangular adaptation plate 802 will descend and leave the gap opening where the adaptation groove 801 communicates with the rectangular groove 703. Then the oil will enter the adaptation groove 801 above the rectangular adaptation plate 802 from the rectangular groove 703. The oil will pass through the through holes and the circular groove 803 on the rectangular adaptation plate 802 as the rectangular pressing plate 702 rises.

[0034] When in use, start the driving motor 402. The driving motor 402 drives the reciprocating screw 403 to rotate. The reciprocating screw 403 drives the movable plate 501 to move up and down reciprocally. The movable plate 501 drives the movable frame 601 to move up and down reciprocally. When the movable frame 601 descends, it drives the extrusion rod 701 to descend. The extrusion rod 701 drives the rectangular extrusion plate 702 to descend. The rectangular extrusion plate 702 extrudes the oil in the transformer oil tank 1. At this time, under the action of the oil pressure, the oil will push the rectangular adaptation plate 802 upward through the circular groove 803, making the rectangular adaptation plate 802 closely adhere to the top inner wall of the adaptation groove 801. At this time, the rectangular adaptation plate 802 also blocks the gap where the adaptation groove 801 communicates with the two rectangular grooves 703. At this time, the oil will not flow above the rectangular extrusion plate 702 through the rectangular extrusion plate 702 and will only be subjected to the downward pressure of the rectangular extrusion plate 702. As the oil pressure below the rectangular extrusion plate 702 becomes larger and larger, the oil will push a number of U-shaped groove oil inlet blocks 303 to move towards the inner wall of the transformer oil tank 1. At this time, the inlet spring 302 undergoes a compressive deformation. When the oil inlet holes 304 on the U-shaped groove oil inlet block 303 enter the oil inlet tank 301, the oil will enter the oil inlet tank 301 from a number of oil inlet holes 304. Then, as the pressure increases, the oil will enter the U-shaped groove 103 in the heat dissipation plate 102 and flow upward along the U-shaped groove 103. At this time, when the reciprocating screw 403 rotates, it drives a number of heat dissipation fan blades 404 to rotate. The wind generated by the heat dissipation fan blades 404 enters the heat dissipation air hood 406 from the air outlet pipe 405. The wind blows out along the heat dissipation air hood 406 to dissipate heat from the surface of the heat dissipation plate 102. The oil entering the U-shaped groove 103 increases the surface area of the oil in contact with the heat dissipation plate 102. When the oil enters the circuit box 104 from the U-shaped groove 103, the oil will first enter the filter box 1071 under the guiding action of the L-shaped plate 105 in cooperation with the inlet pipe 107. Under the action of the pressure, the oil will enter the outer wall of the L-shaped plate 105 through the L-shaped filter plate 108 and the circuit pipe 106 and then return to the circuit box 104 again. At this time, when the oil passes through the L-shaped filter plate 108, the oxides and metal particles in the oil will be filtered onto the L-shaped collection drawer 109 in the filter box 1071. The L-shaped collection drawer 109 can be taken out regularly to clean the oxides and metal impurities to ensure that the oxides and metal particles will not enter the transformer oil tank 1 again; The filtered oil will enter the oil outlet tank 201 through the circuit tank 104. Under the action of pressure, the oil will push the U-shaped groove oil outlet block 203 to move away from the inner wall of the transformer tank 1. At this time, the oil outlet spring 202 undergoes a tensile deformation. When the oil outlet hole 204 on the U-shaped groove oil outlet block 203 leaves the oil outlet tank 201, the oil will flow out again from the oil outlet hole 204 and enter the transformer tank 1. When the movable plate 501 rises, the corresponding extrusion rod 701 will also drive the rectangular extrusion plate 702 to rise. At this time, the rectangular extrusion plate 702 drives the rectangular adaptor plate 802 in the adaptor groove 801 to rise. The oil will enter the rectangular groove 703 through several oil leakage holes 704. Under the action of inertia, the rectangular adaptor plate 802 will descend and leave the gap opening where the adaptor groove 801 communicates with the rectangular groove 703. Then the oil will enter the space above the rectangular adaptor plate 802 in the adaptor groove 801 from the rectangular groove 703. The oil will pass through the through holes and the circular groove 803 on the rectangular adaptor plate 802 as the rectangular extrusion plate 702 rises. During the rising process of the rectangular extrusion plate 702, part of the oil will be driven to rise. At this time, the rising oil will push the U-shaped groove oil outlet block 203 to move towards the inner wall of the transformer tank 1. At this time, the oil outlet hole 204 will enter the oil outlet tank 201. At this time, during the continuous reciprocating movement of the movable plate 501 up and down, the oil in the transformer tank 1 will continuously circulate and dissipate heat. When the oil temperature in the transformer tank 1 is too high, the rotation speed of the drive motor 402 will also increase accordingly to enhance the heat dissipation effect and achieve intelligent temperature control. During the reciprocating movement of the movable plate 501 up and down, the corresponding movable frame 601 will drive the rectangular hollow frame 602 to move. The rectangular hollow frame 602 will drive several cleaning plates 603 to clean the dust and impurities adhered to the surfaces of several heat dissipation plates 102. The dust scraped off by the cleaning plates 603 will be blown away by the wind blown out by the heat dissipation air hood 406, preventing the dust from falling into the heat dissipation air hood 406.
