Description

Technical Field

[0001] This invention relates to the field of transformer technology, specifically to a transformer that is easy to install and remove. Background Technology

[0002] In power systems and electronic equipment, transformers are core components used for voltage conversion and power transmission. Traditional transformers are usually large and heavy, making installation and maintenance inconvenient, especially in scenarios with limited space or frequent relocation. Operation is complex and time-consuming. With technological advancements, users have placed higher demands on the portability, ease of installation, and convenience of maintenance of transformers.

[0003] Patent application CN202410024621.7 discloses a transformer that is easy to install and remove, including a distribution cabinet body, an installation structure, a fixing structure, a support structure, a limiting structure, a wiring structure, a transformer body, and channel steel.

[0004] In summary, when replacing or repairing the transformer inside a small modular distribution cabinet, the limited space at the bottom of the distribution cabinet makes it difficult to carry out maintenance work smoothly and greatly reduces work efficiency when it is necessary to repair or replace components at the bottom of the transformer. This is because the space reserved at the bottom of the distribution cabinet is very small.

[0005] Therefore, we propose a transformer that is easy to install and remove. Summary of the Invention

An adjusting rod is rotatably connected to the end of the first rotating rod away from the first motor via a rotating shaft. The outer wall of the adjusting rod away from the first rotating rod is rotatably connected to a second rotating rod via a rotating shaft. The adjusting rod causes the second rotating rod, which rotates the inner wall of the fixed rod, to rotate at the same angle.

[0011] According to the above technical solution, a connecting shaft is fixedly connected to the bottom outer wall of the adjusting rod, and a force-bearing plate is provided at the top of the adjusting rod. A connecting shaft is fixedly connected to the outer wall of the force-bearing plate on the side close to the adjusting rod. The end of the connecting shaft away from the force-bearing plate passes through the adjusting rod and is fixedly connected to a limiting plate. The limiting plate is used to limit the sliding distance of the force-bearing plate, and the connecting shaft is used to improve the stability of the force-bearing plate during the sliding process.

[0012] According to the above technical solution, the limiting plate is movably sleeved on the outer surface of the first fixed shaft, and a spring is fixedly connected to the outer wall of the limiting plate near the force plate. The end of the spring away from the limiting plate is fixedly connected to the adjusting rod, and the spring is used to reset the force plate.

[0013] According to the above technical solution, the support assembly includes an adjustment frame rotatably connected to the second rotating rod. The outer surface of the adjustment frame is provided with a second sliding groove. A second motor is fixedly connected to the outer surface of the adjustment frame away from the second sliding groove. A support frame is provided at the output end of the second motor.

[0015] According to the above technical solution, the outer surface of the support frame is provided with an installation groove, which is fixedly connected to the transformer equipment by bolts. The inner wall of the support frame is rotatably connected to a third rotating rod via a rotating shaft. The end of the third rotating rod away from the support frame is rotatably connected to a sliding block via a rotating shaft. The sliding block is slidably connected to the inner wall of a second sliding groove, which is used to limit the sliding distance of the sliding block.

[0016] Compared with the prior art, the present invention provides a transformer that is easy to install and remove, and has the following beneficial effects:

[0017] 1. This invention provides a transformer that is easy to install and remove. When replacing or repairing the transformer equipment inside a small modular distribution cabinet, if it is necessary to repair or replace the parts at the bottom of the transformer equipment, the bottom of the transformer equipment is kept at a certain height from the distribution cabinet by an adjustment mechanism. This provides a certain amount of operating space at the bottom of the transformer equipment, which facilitates maintenance work on the equipment at the bottom of the distribution cabinet and improves work efficiency.

[0018] 2. By setting up a sliding frame, using rollers for sliding connection in the first sliding groove, and the support of the second fixed shaft for the support frame, the present invention ensures the stability of the transformer equipment during movement, avoids tilting or shaking of the equipment during movement, and reduces the risk of equipment damage.

[0019] 3. This invention, by setting up an adjustment mechanism, ensures that when adjusting the height of the transformer equipment, the two second rotating rods rotatably connected to the outer wall of the transformer equipment will deflect synchronously, guaranteeing that the deflection angles of the two rods are always the same. In this way, the horizontal height of the adjustment frame connected to the top of the second rotating rods changes accordingly and can always be maintained in a horizontal state, thereby improving the stability of the transformer equipment when the adjustment frame is at different heights.

[0020] 4. By setting up a support component, when the transformer is at a certain height and extends out of the distribution cabinet, the second motor starts to drive the support frame to move towards the second cabinet door. During the sliding process of the support frame, the third rotating rod drives the sliding block to slide on the inner wall of the second sliding groove, thereby enhancing the stability of the end of the support frame away from the second motor and effectively avoiding the situation where one end of the support frame is suspended during movement.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0032] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0033] Example 1: See Figures 1-6The present invention provides a technical solution: a transformer that is easy to install and remove, including a distribution cabinet 1, a first cabinet door 2 that is rotatably connected to the front of the distribution cabinet 1 via a hinge, a second cabinet door 3 that is rotatably connected to the side of the distribution cabinet 1 away from the first cabinet door 2 via a hinge, and further comprising:

[0034] The adjusting mechanism 4 includes a fixed frame 401 fixedly connected to the distribution cabinet 1. A first sliding groove 402 is formed on the outer surface of the fixed frame 401 on the side away from the distribution cabinet 1. A hydraulic rod 403 is fixedly connected to the inner wall of the fixed frame 401 near the first cabinet door 2. The output end of the hydraulic rod 403 passes through the fixed frame 401 and is fixedly connected to a sliding frame 404. A fixed rod 405 is fixedly connected to the outer wall of the sliding frame 404 away from the hydraulic rod 403. A second rotating rod 415 is rotatably connected to the inner wall of the fixed rod 405 via a rotating shaft. A support assembly 416 is provided at the end of the second rotating rod 415 away from the fixed rod 405. A transformer device 5 is provided on the top of the support assembly 416. The first sliding groove 402 limits the sliding distance of the sliding frame 404. The function is that the outer wall of the fixed rod 405 away from the sliding frame 404 is rotatably connected to the roller 406 via a rotating shaft. The outer surface of the roller 406 is slidably connected to the inner wall of the first sliding groove 402. The roller 406 is used to improve the stability of the sliding frame 404 during movement. When loading and unloading the transformer equipment 5, the first cabinet door 2 and the second cabinet door 3 are opened first, then the connecting wires on the equipment are disconnected, and then the hydraulic rod 403 is used to push the sliding frame 404 to move the transformer equipment 5 towards the second cabinet door 3. When the sliding frame 404 is moving, the roller 406 on the fixed rod 405 rolls along the inner wall of the first sliding groove 402 on the outer surface, thereby driving the support assembly 416 to smoothly push the transformer equipment 5 towards the second cabinet door 3.

[0035] A first motor 407 is fixedly connected to the outer wall of the fixed rod 405 near the sliding frame 404. The output end of the first motor 407 passes through the fixed rod 405 and is rotatably connected to a first rotating rod 408 via a rotating shaft. An adjusting rod 409 is rotatably connected to the end of the first rotating rod 408 away from the first motor 407 via a rotating shaft. The outer wall of the adjusting rod 409 away from the first rotating rod 408 is rotatably connected to a second rotating rod 415 via a rotating shaft. The adjusting rod 409 causes the second rotating rod 415, which rotates the inner wall of the fixed rod 405, to rotate at the same angle. During the process of the transformer equipment 5 moving towards the second cabinet door 3, the first sliding groove 402 restricts the movement range of the sliding frame 404, leading to... Since the transformer 5 cannot fully extend from the distribution cabinet 1, while the hydraulic rod 403 pushes the sliding frame 404 to move towards the second cabinet door 3, the first motor 407 drives the first rotating rod 408 to rotate, which in turn causes the adjusting rod 409 to deflect. During the deflection of the adjusting rod 409, it deflects synchronously through the second rotating rod 415 rotatably connected to its outer wall, so that the deflection angles of the two second rotating rods 415 are consistent. This allows the horizontal height of the adjusting frame 4161 connected to the top of the second rotating rod 415 to be adjusted, while ensuring that the adjusting frame 4161 always remains horizontal, thereby improving the stability of the transformer 5 when the adjusting frame 4161 deflects to different heights.

[0036] A connecting shaft 411 is fixedly connected to the bottom outer wall of the adjusting rod 409. A force-bearing plate 410 is provided at the top of the adjusting rod 409. The connecting shaft 411 is fixedly connected to the outer wall of the force-bearing plate 410 near the adjusting rod 409. The end of the connecting shaft 411 away from the force-bearing plate 410 passes through the adjusting rod 409 and is fixedly connected to a limiting plate 412. The limiting plate 412 is used to limit the sliding distance of the force-bearing plate 410. The connecting shaft 411 is used to improve the stability of the force-bearing plate 410 during the sliding process. The limiting plate 412 is movably sleeved on the outer surface of the first fixed shaft 414. The limiting plate 412 is close to the force-bearing plate. A spring 413 is fixedly connected to one side of the outer wall of 410. The end of the spring 413 away from the limiting plate 412 is fixedly connected to the adjusting rod 409. When the force plate 410 is squeezed, the force plate 410 drives the limiting plate 412 to slide towards the bottom of the distribution cabinet 1 through the connecting shaft 411. During this process, the force plate 410 stretches the spring 413 at the same time. After the transformer equipment 5 is replaced, the first motor 407 drives the adjusting frame 4161 to flip into the distribution cabinet 1 through the first rotating rod 408. At this time, the limiting plate 412 returns to its initial position through the connecting shaft 411 under the action of the spring 413.

[0037] The support assembly 416 includes an adjusting frame 4161 rotatably connected to the second rotating rod 415. A second sliding groove 4162 is formed on the outer surface of the adjusting frame 4161. A second motor 4164 is fixedly connected to the outer surface of the adjusting frame 4161 on the side away from the second sliding groove 4162. A support frame 4166 is provided at the output end of the second motor 4164. The second rotating rod 415 is used to adjust the horizontal height of the adjusting frame 4161. During the process of the second rotating rod 415 driving the adjusting frame 4161 to deflect, the adjusting frame 4161 is slidably connected to the support frame on its inner wall. 4166, by using the pressure plate 4168 fixedly connected to the bottom of the support frame 4166 to apply pressure to the force plate 410, when the second rotating rod 415 completely flips the adjusting frame 4161 and completely moves the support frame 4166 out of the distribution cabinet 1, the force plate 410 pushes the limiting plate 412 to move towards the second cabinet door 3 at the bottom of the distribution cabinet 1 through the connecting shaft 411. After the force plate 410 contacts the second cabinet door 3, the supporting force of the force plate 410 on the bottom of the support frame 4166 is further enhanced, thereby improving the stability of the transformer equipment 5 when it is removed from the support frame 4166.

[0038] Example 2: Please refer to Figures 7-8 Based on Embodiment 1, the present invention provides the following technical solution: A rotating shaft 4165 is fixedly connected to the output end of the second motor 4164; a second fixed shaft 4163 is fixedly connected to the inner wall of the adjusting frame 4161; the inner wall of the support frame 4166 is slidably connected to the rotating shaft 4165; the inner wall of the support frame 4166 at the end away from the rotating shaft 4165 is slidably connected to the second fixed shaft 4163; and a pressure plate 4168 is fixedly connected to the outer wall of the support frame 4166 on the side closest to the second fixed shaft 4163. When it is necessary to completely push the transformer 5 out of the distribution cabinet 1... At that time, the second motor 4164 pushes the support frame 4166 towards the second cabinet door 3 through the rotating shaft 4165 fixedly connected to its output end. During the movement of the support frame 4166, its inner wall is slidably connected to the second fixed shaft 4163, thereby providing stability for the sliding of the support frame 4166 through the second fixed shaft 4163. The second motor 4164 ensures through the rotating shaft 4165 that the support frame 4166 drives the transformer equipment 5 to always be located in the central area of ​​the regulating frame 4161, thereby enhancing the stability of the transformer equipment 5 inside the distribution cabinet 1.

[0039] The outer surface of the support frame 4166 has a mounting groove 4167, which is fixedly connected to the transformer equipment 5 by bolts. A third rotating rod 4169 is rotatably connected to the inner wall of the support frame 4166 via a rotating shaft. A sliding block 41610 is rotatably connected to the end of the third rotating rod 4169 away from the support frame 4166 via a rotating shaft. The sliding block 41610 is slidably connected to the inner wall of a second sliding groove 4162, which limits the sliding distance of the sliding block 41610. Under the drive of the second motor 4164, the support... When the support frame 4166 moves toward the second cabinet door 3, the sliding block 41610 is driven to slide on the inner wall of the second sliding groove 4162 by the third rotating rod 4169, thereby enhancing the stability of the end of the support frame 4166 away from the second motor 4164. This prevents the end of the support frame 4166 away from the second motor 4164 from being suspended during the movement, and prevents the heavy transformer equipment 5 from excessively squeezing the support frame 4166, thus protecting the support frame 4166 from damage. At the same time, it improves the stability of the transformer equipment 5 during the loading and unloading process.
