Description

Technical Field

[0001] The present application relates to the field of power transformer oil tanks, and in particular, to a distribution power transformer oil tank structure. Background Art

[0002] The transformer oil pillow is installed on the transformer's oil tank (corrugated oil tank). There is also a pipe sealed with "glass", called an "explosion-proof pipe". This is to prevent the oil temperature from rising rapidly and the volume from expanding rapidly when the transformer fails. When the oil pillow can no longer contain the oil, the oil flow will squeeze the glass and rush out of the explosion-proof pipe, protecting the transformer from major damage.

[0003] For example, the Chinese patent publication number is CN118888276A, and the technical solution disclosed in the patent document is as follows: an amorphous alloy three-dimensional rolled iron core power transformer oil tank structure, including a transformer oil tank body, the bottom surface of the transformer oil tank body is fixedly connected to a functional box, and the functional box is provided with an automatic drying mechanism. The present invention provides power for subsequent drying components and disturbing components by setting a power component and utilizing outdoor wind power. By setting a transmission component, the power generated by the power component is transmitted, so that the drying component can operate efficiently. By setting a drying component, the connection structure at the bottom of the transformer oil tank body can be dried under the drive of wind. By setting a disturbing component, the flying birds perched on the transformer oil tank can be effectively disturbed, reducing the factors that cause damage to the transformer oil tank from the outside, and ensuring that the transformer oil tank can work efficiently and safely. The following problems exist in the prior art: The drying components in the above scheme mainly rely on external wind power (such as the transformer oil tank body is installed at a high place, and the wind power drives the power plate to rotate) to drive the system. However, the size and stability of the wind power may be affected by external climate and environmental factors, resulting in the system being unable to operate effectively when the wind power is insufficient. In particular, if the wind power is not strong, the fan blades may not rotate enough, affecting the drying effect. Summary of the invention

The other end of the hydraulic rod A is fixedly connected to the circular block. A hydraulic rod B is slidably connected to the inside of the other end of the hydraulic chamber. The other end of the hydraulic rod B is fixedly connected to the U-shaped plate.

[0006] Preferably, a slide rail is fixedly connected to the inner bottom end of the drying box, and the U-shaped plate is slidably connected to the upper end of the slide rail.

[0007] Preferably, a spring is movably sleeved on the outer wall of the hydraulic rod A, and the two ends of the spring are respectively fixedly connected to the circular block and the hydraulic chamber.

[0008] Preferably, a fixed block is fixedly connected to the outer wall of the U-shaped plate, and a trigger rod is fixedly connected to the middle of the fixed block. A start switch and a stop switch are arranged inside the drying box.

[0009] Preferably, a bird repelling component is arranged on the top of the transformer body. The bird repelling component includes a driving wheel A which is fixedly sleeved on the outer wall of a rotating shaft on one side. A transmission belt is wound around the outer wall of the driving wheel A. The inner side of the upper end of the transmission belt is in transmission connection with a driving wheel B.

The reciprocating lead screw is rotatably connected to the mounting block through a bearing. A moving block is threadedly connected to the outer wall of the reciprocating lead screw. Disturbing bird plates are fixedly connected to both sides of the moving block.

[0010] Preferably, the bottom of the moving block is slidably connected to the top of the transformer body.

[0012] Preferably, a sliding groove is opened on an inner wall of the drying box. The connecting block is slidably connected inside the sliding groove.

[0013] The advantages of the present application are as follows: (1). The drying component of the present application is located inside the drying box of the transformer, which plays a role in removing moisture and maintaining a dry environment, avoiding moisture absorption of the transformer during use. The drying component inside the drying box helps to discharge moisture through the wind flow of the fan blades, ensuring that the humidity inside the drying box is appropriate, preventing moisture accumulation, and maintaining a normal operating environment for the transformer. When the wind force is sufficient, the windward plate drives the hydraulic rod, and then drives the U-shaped plate and the motor, ensuring that the fan (fan blades) can rotate continuously. This process improves the wind flow efficiency and further accelerates the discharge of moisture, thereby improving the operating efficiency of the transformer. When the wind force is insufficient, the cooperation of the spring and the hydraulic system enables the drying component to reset, and the motor is started to drive the fan blades to rotate, thereby reducing the dependence on external wind force and achieving the purpose of saving energy.

[0014] (2). The main function of the bird repelling component of the present application is to prevent birds from perching on the transformer, reduce the corrosion of the transformer by bird droppings, and reduce potential safety hazards. By swinging the bird disturbing plate left and right, the birds perching on the surface of the transformer can be effectively driven away. When the birds feel the disturbance, they usually leave the transformer, reducing the accumulation of bird droppings on the surface of the transformer, thereby avoiding potential failures and safety problems caused by corrosion. The bird repelling component drives the bird disturbing plate to swing through the movement of the rotating shaft and the transmission belt. This process is completely completed by mechanical means and can automatically perform bird repelling operations without manual intervention, ensuring a long-term and stable bird repelling effect. Through the operation of the bird repelling component, the surface of the transformer can be kept clean, avoiding the corrosion of the external structure by bird droppings, reducing the frequency of maintenance and cleaning, and reducing the maintenance cost.

[0015] (3) The ventilation component of this application plays an important role inside the drying oven, helping to improve air circulation, remove moisture, and maintain the stability of temperature and humidity. Through the movement of the pull rod and connecting rod, the ventilation plate can effectively open the ventilation slots, increasing the space for air circulation and enabling the moisture inside the drying oven to be quickly discharged. This helps to improve the drying efficiency and ensure that the environment inside the transformer oil tank always maintains suitable temperature and humidity. The opening and closing of the ventilation plate are controlled by the movement of the U-shaped plate, and the ventilation volume can be automatically adjusted according to the actual needs inside the drying oven to ensure the discharge of moisture and the entry of fresh air inside the drying oven. At the same time, even when the ventilation slots are closed, the ventilation holes on the ventilation plate can still maintain a certain ventilation effect to avoid moisture accumulation. The rotation of the fan blades driven by wind can accelerate air flow, thereby helping to discharge moisture and reduce the accumulation of humidity inside the transformer, effectively improving the working efficiency of the drying oven.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] Example 1 See also Figure 1-Figure 5 The present embodiment provides a distribution power transformer oil tank structure, including a mounting base 1, which is used to fix the entire transformer oil tank structure and provide stable support. The upper end of the mounting base 1 is fixedly connected to a support plate 2, the upper end of the support plate 2 is fixedly connected to a transformer body 3, the bottom of the transformer body 3 is fixedly connected to a drying box 4, and a drying component 5 is arranged inside the drying box 4; The drying component 5 includes a U-shaped plate 51, which is the core structure inside the drying box 4 and plays the roles of support and movement. The U-shaped plate 51 is arranged inside the drying box 4. A transmission shaft 52 is rotatably connected to the inner side of the U-shaped plate 51. The other end of the transmission shaft 52 penetrates through the U-shaped plate 51 and one side of the drying box 4. A power plate 53 is fixedly connected to the outer wall of one side of the transmission shaft 52 located outside the drying box 4. A bevel gear A54 is fixedly connected to the other end of the transmission shaft 52. A motor 55 is fixedly connected to the inner side of the U-shaped plate 51. A bevel gear B56 is fixedly connected to the output end of the motor 55. Ventilation openings 57 are formed on both sides of the drying box 4. A rotating shaft 58 is rotatably connected to the inside of the ventilation opening 57 through a mounting bracket. A bevel gear C59 is fixedly connected to one end of the rotating shaft 58. A fan blade 510 is fixedly connected to the outer wall of the rotating shaft 58. A mounting shaft 511 is rotatably connected to the outer wall of the drying box 4. A windward plate 512 is fixedly connected to the outer wall of the mounting shaft 511. A connecting rod 513 is hinged to the outer wall of the windward plate 512. The other end of the connecting rod 513 is hinged to a circular block 514. A hydraulic chamber 515 is fixedly connected to one side of the drying box 4. Both ends of the hydraulic chamber 515 are located inside and outside the drying box 4 respectively. A hydraulic rod A516 is slidably connected to the inside of one end of the hydraulic chamber 515 located inside the drying box 4. The other end of the hydraulic rod A516 is fixedly connected to the circular block 514. A hydraulic rod B517 is slidably connected to the inside of the other end of the hydraulic chamber 515. The other end of the hydraulic rod B517 is fixedly connected to the U-shaped plate 51.

[0025] A slide rail 518 is fixedly connected to the inner bottom end of the drying box 4. The U-shaped plate 51 is slidably connected to the upper end of the slide rail 518.

[0026] A spring 519 is movably sleeved on the outer wall of the hydraulic rod A516. Both ends of the spring 519 are fixedly connected to the circular block 514 and the hydraulic chamber 515 respectively, which is used for the reset mechanism to ensure that the hydraulic rod A516 can be reset when there is no wind or the wind force is insufficient, and to adjust the working mode of the drying system.

[0027] A fixing block 520 is fixedly connected to the outer wall of the C-shaped plate 51, a trigger rod 521 is fixedly connected to the middle of the fixing block 520, and a start switch 522 and a stop switch 523 are arranged inside the drying box 4. During use, when the wind force is strong enough, the wind force will cause the windward plate 512 to rotate inward along the mounting shaft 511. Then, the connecting rod 513 hinged to the side of the windward plate 512 will drive the hydraulic rod A516 to slide into the hydraulic chamber 515 by pushing the circular block 514. Then, the hydraulic rod B517 slidably connected to the other end inside the hydraulic chamber 515 will slide outward, thereby pushing the C-shaped plate 51 to slide on the outer wall of the slide rail 518, and then the transmission shaft 52 can be driven to move into the drying box 4. At the same time, the motor 55 on the inner wall of the C-shaped plate 51 will also move. Then, the bevel gear B56 at the output end of the motor 55 will disengage from the bevel gear C59. At the same time, the trigger rod 521 fixedly connected to the side of the C-shaped plate 51 through the fixing block 520 will also move accordingly and trigger the stop switch 523, so that the motor 55 is turned off. Then, the bevel gear A54 fixedly connected to the transmission shaft 52 will engage with the bevel gears C59 on both sides. At the same time, the power plate 53 on the outer wall of the transmission shaft 52 will rotate under the action of the wind force, so the transmission shaft 52 will also rotate accordingly, driving the bevel gear A54 to rotate. Then, the meshing bevel gear C59 will rotate, driving the rotating shaft 58 to rotate. The rotation of the rotating shaft 58 can drive the fan blade 510 to rotate, thereby delivering wind into the drying box 4, ensuring that the bottom of the drying box 4 remains dry. When the wind force is too small, the spring 519 will push the circular block 514 to move sideways, and then the windward plate 512 will be reset through the connecting rod 513. At the same time, the hydraulic rod A516 will slide outward inside the hydraulic chamber 515, and then the hydraulic rod B517 will slide into the hydraulic chamber 515, driving the C-shaped plate 51 to slide forward on the outer wall of the slide rail 518, so that the bevel gear B56 engages with the bevel gear C59, while the bevel gear A54 disengages from the bevel gear C59. At the same time, the trigger rod 521 will also move accordingly and press the start switch 522 to start the motor 55. Then, the motor 55 will drive the bevel gear B56 to rotate. At this time, the meshing bevel gear C59 will drive the rotating shaft 58 to rotate accordingly, and then the fan blade 510 will rotate, ensuring the continuous rotation of the fan blade 510. When the wind force is insufficient, the motor 55 is started to drive the fan blade 510 to rotate in cooperation, which not only saves electricity but also provides a backup for the motor 55.

[0028] Embodiment 2 See Figure 1-Figure 6The top of the transformer body 3 is provided with a bird-repelling assembly 6, the main purpose of which is to prevent birds from perching on the transformer, reduce the corrosion of the transformer surface by bird droppings and other possible safety hazards. The bird-repelling plate 67 is mechanically made to swing left and right to drive away birds. The bird-repelling assembly 6 includes a transmission wheel A61, which is fixedly sleeved on the outer wall of the rotating shaft 58 on one side, and a transmission belt 62 is wound around the outer wall of the transmission wheel A61. The upper end of the transmission belt 62 is connected to the inner side of the transmission wheel B63. The top of the transformer body 3 is fixedly connected with a mounting block 64, and the outer wall of the transmission wheel B63 is fixedly connected with a reciprocating screw 65. The reciprocating screw 65 is rotatably connected to the mounting block 64 through a bearing, and the outer wall of the reciprocating screw 65 is threadedly connected with a moving block 66. The two sides of the moving block 66 are fixedly connected with bird-repelling plates 67, which swing left and right through the action of the moving block 66 to achieve the effect of driving away perching birds. The bottom of the moving block 66 is slidably connected to the top of the transformer body 3.

[0029] During use, when the rotating shaft 58 rotates, a transmission wheel A61 is fixedly sleeved on the outer wall of the rotating shaft 58. As the rotating shaft 58 rotates, the transmission wheel A61 will also be driven to rotate. The transmission wheel A61 is connected to the transmission belt 62, so when the transmission wheel A61 rotates, the transmission belt 62 will also move, and the inner side of the upper end of the transmission belt 62 is connected to the transmission wheel B63. When the transmission belt 62 moves due to the rotation of the transmission wheel A61, it will drive the transmission wheel B63 to rotate. The transmission wheel B63 is fixedly connected to the reciprocating screw rod 65, so the rotation of the transmission wheel B63 will cause the reciprocating screw rod 65 to rotate together. Since the reciprocating screw rod 65 is fixedly connected to the transmission wheel B63, when the transmission wheel B63 rotates, the reciprocating screw rod 65 will also rotate accordingly. There is a thread on the outer wall of the reciprocating screw 65, and the thread is connected to the moving block 66, so when the reciprocating screw 65 rotates, the moving block 66 will reciprocate along the thread of the screw, and the moving block 66 is slidably connected to the top of the transformer body 3. As the reciprocating screw 65 rotates, the moving block 66 will slide along the top of the transformer body 3 and reciprocate left and right on the top of the transformer. At this time, the bird-disturbing plates 67 fixedly connected on both sides of the moving block 66 will also swing left and right with the movement of the moving block 66, and the action of the moving block 66 causes the bird-disturbing plates 67 on both sides to swing left and right. When the bird-disturbing plates 67 swing left and right, they mechanically drive away the birds perched on the transformer body 3. Birds will fly away from the transformer due to being disturbed, thereby preventing them from perching on the surface of the transformer, reducing the corrosion of the transformer by bird droppings and the potential safety hazards.

[0030] Example 3 See also Figure 1-Figure 7, a ventilation component 7 is provided on one outer wall of the drying oven 4. The main function of the ventilation component 7 is to control the ventilation and air circulation inside the drying oven 4, ensure the discharge of moisture inside the drying oven 4, and maintain a stable temperature and humidity environment. The ventilation component 7 includes an installation groove 71 which is opened inside the drying oven 4. A ventilation groove 72 is opened on the inner wall of the drying oven 4. A connecting shaft 73 is fixedly connected to the inner wall of the U-shaped plate 51. A pull rod 74 is movably sleeved on the outer wall of the connecting shaft 73. The other end of the pull rod 74 is rotatably connected to a connecting block 75 through a pin shaft. A ventilation plate 76 is fixedly connected to the outer wall of the connecting block 75. Ventilation holes 77 are opened on the outer wall of the ventilation plate 76. A sliding groove 78 is opened on the inner wall of the drying oven 4. The connecting block 75 is slidably connected inside the sliding groove 78, and the sliding groove 78 provides a path for the connecting block 75 to slide.

[0031] During use, when the U-shaped plate 51 moves towards the ventilation groove 72, the connecting shaft 73 at the upper end of the U-shaped plate 51 will also move along with the U-shaped plate 51. Due to the fixed connection relationship between the connecting shaft 73 and the U-shaped plate 51, the movement of the U-shaped plate 51 will directly drive the movement of the connecting shaft 73. The upper end of the connecting shaft 73 is connected to the pull rod 74, and the movement of the pull rod 74 will cause the pull rod 74 at its other end to push towards both sides. The pull rod 74 is connected to the connecting block 75 through a pin shaft. Along with the movement of the pull rod 74, the connecting block 75 will also slide inside the sliding groove 78. When the connecting block 75 slides inside the sliding groove 78, it pushes the ventilation plate 76 to move along the direction of the sliding groove 78. At this time, the movement of the connecting block 75 causes the ventilation plate 76 to enter the inside of the installation groove 71, thereby enabling the ventilation groove 72 to be completely opened. The core function of this process is to expose the ventilation groove 72 inside the drying oven 4 completely through the movement of the mechanical structure, increase the space for air circulation, ensure that moisture can be quickly discharged, and maintain the stability of the internal temperature and humidity. After the ventilation groove 72 is completely opened, the fan blade 510 driven by wind starts to work. The rotation of the fan blade 510 can accelerate the air flow and enhance the air circulation effect inside the drying oven 4. This helps to more effectively remove the moisture inside the drying oven 4 and guide it to the outside, thereby improving the drying efficiency. When the U-shaped plate 51 moves away from the ventilation groove 72, the movement directions of the connecting shaft 73 and the pull rod 74 are reversed, and the pull rod 74 and the pull rod 74 drive the connecting block 75 to slide towards the center of the sliding groove 78. This movement causes the ventilation plate 76 to slide from the inside of the installation groove 71 towards the middle, gradually covering and closing the ventilation groove 72. At this time, the ventilation groove 72 is closed again, preventing the entry of external air. When the ventilation groove 72 is closed, the fan blade 510 still continues to rotate driven by the motor 55. At this time, the ventilation effect depends on the ventilation holes 77 opened on the ventilation plate 76. The existence of the ventilation holes 77 enables a certain degree of ventilation to still occur inside the drying oven 4 even when the ventilation groove 72 is closed, ensuring the discharge of moisture inside the drying oven 4 and the entry of fresh air, thereby maintaining a stable internal temperature and humidity environment.
