Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and in particular to a transformer with a joint protection structure. Background Art

[0002] Transformers are critical components of power transmission and distribution systems, ensuring their reliability and safety. Transformers typically include one or more connectors that connect the transmission lines to the distribution network. These connectors, typically located at the top of the transformer, are a crucial electrical connection and play a vital role in ensuring safe and efficient power transmission.

[0003] Existing transformer protection structures mostly focus on protecting the overall casing of the transformer, that is, by setting up buffer structures around it to resist external physical impact. Although this type of design can protect the transformer body from external collisions and mechanical damage to a certain extent, they ignore the targeted protection of the joints. Especially when the transformer is installed in an outdoor environment, in addition to facing the challenges brought by the natural environment (such as wind, rain, birds, etc.), it is also necessary to consider the risk of accidental collisions during construction and maintenance. The only rainproof or bird-proof structures currently on the market for the top of the transformer are mostly simple in design and single in function. For example, a simple roof structure can provide basic protection to a certain extent, but it cannot fully guarantee the safety of the joints and may hinder daily inspection and maintenance work.

[0004] In view of the above situation, the present invention proposes a transformer with a joint protection structure, which can achieve comprehensive protection of the top joint area, not only effectively preventing external objects from causing direct impact damage to the joint, but also will not affect the convenience of necessary inspection and maintenance work. Summary of the Invention

[0005] In order to overcome the disadvantage that if the transformer joints are hit by external forces or improper operation, they may cause electrical failures, short circuits or even more serious accidents. Most of the transformer protection structures in the existing technology act on the transformer body and lack targeted protection for the joints. The present invention provides a transformer with a joint protection structure. This transformer can achieve comprehensive protection for the top joint area, not only effectively preventing direct impact damage to the joints by external objects, but also will not affect the convenience of necessary inspection and maintenance work.

[0006] The technical implementation scheme of the present invention is: a transformer with a joint protection structure, including a transformer body, and also including two longitudinally symmetrical sliding frames, the two longitudinally symmetrical sliding frames are slidably connected to the transformer body, a protective shell is fixedly connected between the top ends of the two sliding frames, and the protective shell cover is on the top of the transformer body to prevent the joint from being hit, a threaded rod is rotatably connected to the transformer body, a connecting plate is fixedly connected between the bottom ends of the two sliding frames, the connecting plate and the threaded rod are threadedly connected, a lifting frame is slidably connected to the top of the protective shell, a top plate is fixedly connected to the top of the lifting frame, four spring telescopic rods are connected between the top plate and the protective shell, a rain shield component is provided on the top plate for adjusting the angle according to the direction of the wind to reduce rainwater entering the protective shell, and a deceleration component is provided on the top plate for slowing down the reset speed of the rain shield component.

[0007] Furthermore, two strip-shaped grooves for power supply lines to pass through are opened on both lateral sides of the protective shell.

[0008] Furthermore, the rain shield assembly includes two longitudinally symmetrical wind shields, which are rotatably connected to the top plate. Two longitudinally symmetrical limit blocks are fixedly connected on both sides of the top plate in the transverse direction, and the limit blocks are in contact with adjacent wind shields. Two first gears are fixedly connected at the rotating connection between the wind shield and the top plate, and rain shields are rotatably connected on both sides of the top plate in the longitudinal direction. Two second gears are fixedly connected at the rotating connection between the rain shield and the top plate, and the second gears are meshed with adjacent first gears. Two transversely symmetrical torsion springs are connected between the rain shield and the top plate.

[0009] Furthermore, the deceleration assembly includes a guide rail, which is fixedly connected to the bottom end of the rain shield, and a sliding block is slidably connected to the guide rail. Two longitudinally symmetrical hollow cylinders are fixedly connected to the bottom end of the top plate, and the sides of the hollow cylinders away from each other are connected to an air inlet pipe with a one-way valve, and the sides of the hollow cylinders away from each other are connected to an air outlet pipe with a one-way valve, the diameter of the air inlet pipe is much larger than the air outlet pipe, a piston is slidably connected to the hollow cylinder, a sliding rod is fixedly connected to the center position of the piston, and the end of the sliding rod away from the piston extends out of the hollow cylinder, the end of the sliding rod away from the piston is fixedly connected to a connecting plate, and the connecting plate is fixedly connected to a connecting rod, and the end of the connecting rod away from the connecting plate is rotatably connected to the adjacent sliding block.

[0010] Furthermore, it also includes a heat dissipation component for dissipating heat at the joints of the transformer body without affecting the inspection. The heat dissipation component includes two longitudinally symmetrical guide bars, which are fixedly connected to the longitudinal sides of the protective shell. Two transversely symmetrical baffles are slidably connected to the guide bars, and a heat dissipation fan is fixedly connected to the baffles. Both longitudinal sides of the protective shell are rotatably connected to bidirectional screw rods, and both transverse ends of the bidirectional screw rods are connected to connecting blocks by threads, and the connecting blocks are fixedly connected to the adjacent baffles.

[0011] Furthermore, it also includes a bird-repelling component for driving away birds, which includes a guide plate, which is fixedly connected to one side of the top plate, a movable plate slidably connected to the guide plate, an electric slide rail fixedly connected to the other side of the top plate, the movable plate and the electric slide rail are slidably connected, a mounting frame fixedly connected to the middle of the movable plate, a bird-repelling frame rotatably connected to the mounting frame, a third gear fixedly connected to the bottom end of the bird-repelling frame, a rack fixedly connected to the middle of the top plate, and the rack meshing with the third gear.

[0012] Furthermore, the top of the bird-repelling frame is provided with equidistantly distributed tassel-shaped hanging strips.

[0013] The beneficial effects of the present invention are: 1. The protective shell cover fully protects the joint area at the top of the transformer body. The wires connected to the joint can pass in and out through the strip grooves on both sides, and the spring telescopic rod is extended and retracted, and the lifting frame and the top plate can slide up and down to buffer the impact force from the upper side, effectively preventing external objects from causing direct impact damage to the joint. When it is windy and rainy, the rain shield rotates downward to block the side of the protective shell in the wind direction to prevent the wind from blowing rain into the protective shell. When checking the joint, it is only necessary to control the baffles on the left and right sides to open back to back. If replacement and maintenance are required, the protective shell can be directly controlled to lift upward to expose the entire area of ​​the top of the transformer body.

[0014] 2. With the cooperation of the large-diameter air inlet pipe and the small-diameter air outlet pipe, the rain shield will not encounter too much resistance when it rotates downward to block the rain, and it will be slowed down when it rotates upward to reset, so that the rain shield can maintain a relatively stable angle to block the rain, avoiding frequent up and down rotation due to changes in wind force during the rain-blocking process.

[0015] 3. During the protection process, the operation of the cooling fan can cool and dissipate heat from the joints inside the protective shell to prevent high temperature from affecting the operation of the transformer body.

[0016] 4. When the movable plate controls the bird-repellent frame to move left and right, the bird-repellent frame will also rotate, driving away birds by moving to prevent birds from staying on the device. When the movable plate moves left and right, impurities such as leaves that fall on the top plate can be pushed out. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0029] Example 1: A transformer with a joint protection structure, such as Figure 1-Figure 7As shown, it includes a transformer body 1, a sliding frame 2, a protective shell 3, a threaded rod 4, a connecting plate 5, a lifting frame 6, a top plate 7, a spring telescopic rod 8, a rain shield assembly and a deceleration assembly. Two sliding frames 2 symmetrically arranged front and back are slidably connected to the transformer body 1. A protective shell 3 is fixedly connected between the upper parts of the two sliding frames 2. The protective shell 3 covers the top of the transformer body 1. Two strip grooves for power supply lines are opened on the left and right sides of the protective shell 3. The threaded rod 4 is rotatably connected to the left side of the transformer body 1. A connecting plate 5 is fixedly connected between the lower left parts of the two sliding frames 2. The connecting plate 5 is threadedly connected to the threaded rod 4. The top of the protective shell 3 is slidably connected to the lifting frame 6. The upper side of the lifting frame 6 is fixedly connected to the top plate 7. Four spring telescopic rods 8 are connected between the top plate 7 and the protective shell 3. The top plate 7 is provided with a rain shield assembly for adjusting according to weather conditions to reduce rainwater entering the protective shell 3. The top plate 7 is provided with a deceleration assembly for slowing down the resetting speed of the rain shield assembly.

[0030] When using the device, the wires connected to the insulated connector of the transformer body 1 can pass through the strip grooves on the left and right sides of the protective shell 3, without affecting the normal circuit connection of the transformer body 1. The protective shell 3 covers the top of the transformer body 1, thereby fully protecting the connector area on the top of the transformer body 1 to prevent impact from the front, back, left and right sides. Under the action of the extension and contraction of the spring telescopic rod 8, the lifting frame 6 and the top plate 7 can slide up and down to buffer the impact force from the upper side, effectively preventing external objects from causing direct impact damage to the connector. During the use of this device, when it rains, if the wind is strong, When the rain falls in a forward and backward tilt, the rain shield assembly can shield the front and rear sides of the protective shell 3, reducing the probability of rainwater entering the protective shell 3 from the front and rear sides, and the deceleration assembly can slow down the resetting speed of the rain shield assembly to avoid frequent rotation of the rain shield assembly. When the joint at the top of the transformer body 1 needs to be inspected and maintained, the staff controls the threaded rod 4 to rotate, and the threaded rod 4 rotates to drive the connecting plate 5 to move upward. The upward movement of the connecting plate 5 drives the sliding frame 2 to slide upward, and the upward sliding of the sliding frame 2 drives the protective shell 3 to be lifted upward, thereby exposing the entire area of ​​the top of the transformer body 1 for maintenance operations.

[0031] like Figure 1 、 Figure 4 and Figure 5As shown, the rain shield assembly includes a windshield 14, a limit block 141, a first gear 15, a rain shield 16, a second gear 17 and a torsion spring 18. The front and rear parts of the top plate 7 are rotatably connected to the wind shield 14. The left and right sides of the top plate 7 are fixedly connected with two limit blocks 141 that are symmetrical in front and back. The limit blocks 141 are in contact with the adjacent wind shield 14. The left and right first gears 15 are fixedly connected to the rotating connection between the wind shield 14 and the top plate 7. The front and rear sides of the top plate 7 are rotatably connected to the rain shield 16. The left and right second gears 17 are fixedly connected to the rotating connection between the rain shield 16 and the top plate 7. The second gear 17 is engaged with the adjacent first gear 15. Two left and right symmetrical torsion springs 18 are connected between the rain shield 16 and the top plate 7.

[0032] In the initial state, the rain shield 16 is in an upwardly raised state to facilitate air circulation and heat dissipation inside the protective shell 3. When it rains, if the wind blowing to the front and rear sides is strong, the wind shield 14 is limited by the limit block 141 and cannot rotate outward, so the wind shield 14 in the incoming wind direction will rotate inward under the action of the wind force. Here, the front wind shield 14 is taken as an example. The wind shield 14 rotates backward to drive the first gear 15 to rotate counterclockwise. The first gear 15 rotates counterclockwise to drive the second gear 17 to rotate clockwise. The second gear 17 rotates clockwise to drive the wind shield The rain plate 16 rotates downward, and the torsion spring 18 is deformed. After the rain shield 16 rotates downward, it blocks the front side of the protective shell 3 to prevent the wind from blowing rain backward into the protective shell 3. When the wind weakens, the wind shield 14 is no longer subjected to the pressure of wind and rain. At this time, under the action of the torsion spring 18 resetting, the rain shield 16 rotates upward and resets, and then the wind shield 14 is driven to rotate forward and reset through the cooperation of the second gear 17 and the first gear 15. In this way, the angle of the rain shield 16 can be adjusted according to the direction of the wind, ensuring the ventilation and heat dissipation effect while reducing the intrusion of rainwater.

[0033] like Figure 1 、 Figure 6 and Figure 7As shown, the deceleration assembly includes a guide rail 19, a sliding block 20, a hollow cylinder 21, an air inlet pipe 211, an air outlet pipe 212, a piston 22, a sliding rod 23, a connecting plate 24 and a connecting rod 25. The left portion of the lower side of the rain shield 16 is fixedly connected to the guide rail 19, and the sliding block 20 is slidably connected to the guide rail 19. The left portion of the lower side of the top plate 7 is fixedly connected to two hollow cylinders 21 that are symmetrical in front and back. The sides of the hollow cylinders 21 that are away from each other are connected to the air inlet pipe 211 with a one-way valve. The sides of the hollow cylinders 21 that are away from each other are connected to the air inlet pipe 211 with a one-way valve. Both sides are connected with an outlet pipe 212 with a one-way valve. The diameter of the air inlet pipe 211 is much larger than that of the air outlet pipe 212. A piston 22 is slidably connected in the hollow cylinder 21. A sliding rod 23 is fixedly connected to the center position of the piston 22. The end of the sliding rod 23 away from the piston 22 extends out of the hollow cylinder 21. The end of the sliding rod 23 away from the piston 22 is fixedly connected to a connecting plate 24. A connecting rod 25 is fixedly connected to the connecting plate 24. The end of the connecting rod 25 away from the connecting plate 24 is rotatably connected to the adjacent sliding block 20.

[0034] When using the device, the rain shield 16 rotates downward to drive the guide rail 19 to rotate downward, and the guide rail 19 rotates downward to push the connecting rod 25 inward through the sliding block 20. The connecting rod 25 moves inward to drive the connecting plate 24 and the sliding rod 23 to slide inward, and the sliding rod 23 slides inward to drive the piston 22 to slide inward. Since the diameter of the air intake pipe 211 is large, the external air can be easily sucked into the hollow cylinder 21 through the air intake pipe 211 when the piston 22 slides inward, which will not cause too much resistance to the downward rotation of the rain shield 16. When the rain shield 16 needs to be turned When the upper part rotates, the guide rail 19 rotates upward and pulls the connecting rod 25 outward through the sliding block 20. The connecting rod 25 moves outward and drives the sliding rod 23 to slide outward through the connecting plate 24, and the piston 22 slides outward accordingly. At this time, due to the small diameter of the air outlet pipe 212, the air in the hollow cylinder 21 can only be discharged slowly, thereby limiting the speed at which the piston 22 slides outward, thereby increasing the resistance to the upward rotation of the rain shield 16, so that the rain shield 16 maintains a relatively stable angle for rain protection, and avoids frequent up and down rotation due to changes in wind force during the rain protection process.

[0035] Example 2: Based on Example 1, Figure 1 and Figure 8 As shown, a heat dissipation component is also included for dissipating heat at the joints of the transformer body 1 without affecting the inspection. The heat dissipation component includes a guide bar 9, a baffle 10, a heat dissipation fan 11, a bidirectional screw rod 12 and a connecting block 13. The upper parts of the front and rear sides of the protective shell 3 are fixedly connected to the guide bar 9, and two baffles 10 symmetrical on the left and right are slidably connected to the guide bar 9. The heat dissipation fan 11 is fixedly connected to the baffle 10. The upper parts of the front and rear sides of the protective shell 3 are rotatably connected to the bidirectional screw rod 12. The left and right parts of the bidirectional screw rod 12 are both connected to the connecting block 13 by threads, and the connecting block 13 is fixedly connected to the adjacent baffle 10.

[0036] In the initial state, the left and right symmetrical baffles 10 block the front and rear sides of the protective shell 3. The operation of the cooling fan 11 can cool and dissipate heat from the joints inside the protective shell 3. When it is necessary to check the condition of the joints at the top of the transformer body 1, the staff rotates the bidirectional screw rod 12. The rotation of the bidirectional screw rod 12 drives the connecting blocks 13 on the left and right sides to move backwards, thereby controlling the left and right symmetrical baffles 10 to open backwards. The baffles 10 are opened backwards to expose the inside of the protective shell 3 for inspection by the staff. If the joints need to be replaced or repaired, the staff controls the threaded rod 4 to rotate and drive the protective shell 3 to lift upward. In this way, the joints of the transformer body 1 can be cooled and maintenance can be facilitated.

[0037] like Figure 1 、 Figure 9 and Figure 10 As shown, it also includes a bird-repelling assembly for driving away birds, which includes a guide plate 26, a movable plate 27, an electric slide rail 28, a mounting frame 29, a bird-repelling frame 30, a third gear 31 and a rack 32. The guide plate 26 is fixedly connected to the rear portion of the upper side of the top plate 7, and the movable plate 27 is slidably connected to the guide plate 26. The front portion of the upper side of the top plate 7 is fixedly connected to the electric slide rail 28, and the front end of the movable plate 27 is slidably connected to the electric slide rail 28. The middle portion of the movable plate 27 is fixedly connected to the mounting frame 29, and the bird-repelling frame 30 is rotatably connected to the mounting frame 29. The upper portion of the bird-repelling frame 30 is provided with equidistantly distributed tassel-shaped hanging strips, the lower portion of the bird-repelling frame 30 is fixedly connected to the third gear 31, and the middle portion of the top plate 7 is fixedly connected to the rack 32, which engages with the third gear 31.

[0038] When using the device, the electric slide rail 28 controls the movable plate 27 to move left and right. The movable plate 27 moves left and right, driving the bird-repelling frame 30 to move left and right through the mounting frame 29. When the bird-repelling frame 30 moves left and right, the third gear 31 engages with the rack 32 to rotate, and the bird-repelling frame 30 rotates accordingly. The bird-repelling frame 30 rotates during the process of moving left and right to drive away birds and prevent them from staying on the device. When the movable plate 27 moves left and right, impurities such as leaves that fall on the top plate 7 can be pushed out.

[0039] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
