Description

Technical Field

[0001] This invention relates to the field of dry-type transformer technology, and more particularly to a modular installation and fixing frame for dry-type transformers. Background Technology

[0002] Dry-type transformers, a common type of transformer in power systems, operate on a similar core principle to oil-immersed transformers, both based on electromagnetic induction to achieve voltage level conversion. However, they differ significantly in their cooling and insulation methods. Dry-type transformers require installation within a frame for ease of use.

[0003] Currently, dry-type transformers use fixed frames. During installation, the transformer body is simply installed between the upper and lower frames. Although this achieves the assembly of the dry-type transformer, it is not conducive to the stable connection between the dry-type transformer and the upper and lower frames during the assembly process, thus affecting the use of the dry-type transformer. Therefore, it is necessary to design a modular installation and fixed frame for dry-type transformers. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a modular installation and fixing frame for dry-type transformers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a modular installation and fixing frame for a dry-type transformer, comprising a lower frame and an upper frame, wherein a transformer body and a vertical frame are disposed between the lower frame and the upper frame, and the upper and lower ends of the transformer body are respectively connected to the lower frame and the upper frame through fixing components; a square column is fixedly connected to the upper end of the lower frame and the lower end of the upper frame, and the square column is slidably connected to the vertical frame; an adjustment mechanism is disposed inside the vertical frame, and the upper and lower ends of the adjustment mechanism are respectively connected to the upper frame and the lower frame; a transmission component is disposed at the rear end of the vertical frame; connecting components are disposed on both the front and rear sides of the lower frame to connect to a fan; a limiting mechanism is disposed inside the lower frame, and the limiting mechanism is used to limit the connecting components; both the lower frame and the upper frame are connected to the transformer body through fixing components.

[0006] As a further description of the above technical solution: The fixing component includes fixing lugs, nuts, and screws. Fixing lugs are fixedly connected to the front and rear sides of the lower frame and the upper frame. A screw is inserted through the fixing lug. The screw is fixedly connected to the transformer body. A nut is threaded onto the screw.

[0007] As a further description of the above technical solution: The adjustment mechanism includes a bidirectional threaded rod, a movable block, a first handle, and a first transmission rod. The bidirectional threaded rod is rotatably connected inside the vertical frame. The movable block is threadedly connected to the circumferential surface of the bidirectional threaded rod. The upper and lower ends of the movable block are rotatably connected to the first transmission rod, and the upper and lower first transmission rods are rotatably connected to the upper frame and the lower frame, respectively. The front end of the bidirectional threaded rod is fixedly connected to the first handle. The movable blocks are symmetrically distributed on the bidirectional threaded rod, and the internal threads of the two movable blocks are in opposite directions.

[0008] As a further description of the above technical solution: The vertical frame has a sliding groove inside, and a slider is slidably connected inside the sliding groove. The slider is fixedly connected to the moving block.

[0009] As a further description of the above technical solution: The transmission assembly includes a bearing housing, a transmission shaft, a first bevel gear, and a second bevel gear. The rear end of the vertical frame is fixedly connected to the bearing housing, and the transmission shaft is rotatably connected inside the bearing housing. Both ends of the transmission shaft are fixedly connected to the second bevel gear, and the front end of the second bevel gear meshes with the first bevel gear. The first bevel gear is fixedly connected to a bidirectional threaded rod.

[0010] As a further description of the above technical solution: The connecting assembly includes a connecting plate, a connector, and a connector block. Connectors are fixedly connected to both sides of the lower frame. A connector block is inserted into the connector. The connector block is fixedly connected to the fan. A connecting plate is fixedly connected to the lower end of the connector block.

[0011] As a further description of the above technical solution: The limiting mechanism includes a limiting rod, a moving rod, a transmission threaded rod, a second handle, a second transmission rod, a limiting rod, and a limiting hole. The limiting rod is fixedly connected inside the lower frame. The moving rod is slidably connected to the limiting rod. The end of the moving rod away from the limiting rod is threadedly connected to the transmission threaded rod. The transmission threaded rod passes through the lower frame and is rotatably connected to the lower frame. The end of the transmission threaded rod is fixedly connected to the second handle. The moving rod is rotatably connected to both sides of the moving rod. The end of the second transmission rod away from the moving rod is rotatably connected to the limiting rod. The lower end of the limiting rod is provided with an inclined surface. The upper surface of the connecting plate is provided with a limiting hole, which corresponds to the limiting rod.

[0012] As a further description of the above technical solution: The lower frame is fixedly connected to the inner wall of the inner wall with a limiting groove, and a limiting block is slidably connected inside the limiting groove. The limiting block is fixedly connected to the limiting rod.

[0013] As a further description of the above technical solution: The upper frame is fixedly connected to both sides of the upper end with four lifting lugs.

[0014] The present invention has the following beneficial effects: 1. Compared with existing technologies, this modular installation and fixing frame for dry-type transformers, by setting up a vertical frame and adjusting components, allows the upper and lower frames to be connected together using the vertical frame and the adjusting components. This enables the dry-type transformer to be stably installed between the upper and lower frames, facilitating the subsequent hoisting of the transformer to the desired location by lifting the upper frame, thus avoiding damage to the transformer body during hoisting. At the same time, the distance between the upper and lower frames can be adjusted with the adjusting components, making it convenient to install transformer bodies of different heights.

[0015] 2. Compared with existing technologies, this modular installation and fixing frame for dry-type transformers, through the setting of a limiting rod, a moving rod, a transmission threaded rod, a second handle, a second transmission rod, a limiting rod, a limiting hole, a connecting plate, a plug-in seat, and a plug-in block, allows for the initial installation of the fan by aligning the plug-in block on the fan with the plug-in seat. After the initial installation of the fan, rotating the second handle, in conjunction with the transmission threaded rod, moves the moving rod on the limiting rod, which in turn, in conjunction with the second transmission rod, moves the limiting rod into the limiting hole, thus limiting the connecting plate. This ensures a stable connection between the fan and the lower frame, enabling the simultaneous installation of multiple fans and improving the installation efficiency of the fans.

Detailed Implementation

[0018] Reference Figure 1-10 The modular installation and fixing frame for dry-type transformers provided by the present invention includes a lower frame 1 and an upper frame 3. A transformer body 5 and a vertical frame 2 are disposed between the lower frame 1 and the upper frame 3. The upper and lower ends of the transformer body 5 are respectively connected to the lower frame 1 and the upper frame 3 through fixing components 7. A square column 14 is fixedly connected to the upper end of the lower frame 1 and the lower end of the upper frame 3. The square column 14 is slidably connected to the vertical frame 2. An adjustment mechanism 6 is disposed inside the vertical frame 2. The upper and lower ends of the adjustment mechanism 6 are respectively connected to the upper frame 3 and the lower frame 1. A transmission component 11 is disposed at the rear end of the vertical frame 2. The front and rear sides of the lower frame 1 are connected to a fan 8 through connecting components 10. A limiting mechanism 9 is disposed inside the lower frame 1 to limit the connecting components 10. The lower frame 1 and the upper frame 3 are both connected to the transformer body 5 through fixing components 7.

[0019] In use, first, adjust the height between the upper frame 3 and the lower frame 1 using the adjusting mechanism 6 according to the height of the transformer body 5. After adjustment, install the transformer body 5 between the upper frame 3 and the lower frame 1. Then, by using the adjusting mechanism 6 to work in reverse, the upper frame 3 and the lower frame 1 can be moved towards the transformer body 5 simultaneously, thereby pressing the transformer body 5. At the same time, with the cooperation of the transmission component 11, it is beneficial for the two sets of adjusting components to work simultaneously, and the two sides of the upper frame 3 and the lower frame 1 can be adjusted at the same time. After pressing the transformer body 5, with the cooperation of the fixing component 7, the transformer body 5 can be stably connected to the frame. Next, the fan 8 is installed. With the cooperation of the connecting component 10, the fan 8 is initially installed. Then, with the cooperation of the limiting mechanism 9, the connecting component 10 is limited, thereby making the fan 8 stably connected to the lower frame 1.

[0020] The fixing component 7 includes a fixing lug 701, a nut 702, and a screw 703. The fixing lug 701 is fixedly connected to both the front and rear sides of the lower frame 1 and the upper frame 3. The screw 703 is installed through the fixing lug 701 and is fixedly connected to the transformer body 5. The nut 702 is threaded onto the screw 703. During operation, the screw 703 on the transformer body 5 is aligned with the fixing lug 701, and with the cooperation of the nut 702, the transformer body 5 can be stably connected to the upper frame 3 and the lower frame 1.

[0021] The adjusting mechanism 6 includes a bidirectional threaded rod 601, a moving block 602, a first handle 603, and a first transmission rod 604. The bidirectional threaded rod 601 is rotatably connected inside the vertical frame 2. The moving block 602 is threadedly connected to the circumferential surface of the bidirectional threaded rod 601. The first transmission rod 604 is rotatably connected to both the upper and lower ends of the moving block 602. The upper and lower first transmission rods 604 are rotatably connected to the upper frame 3 and the lower frame 1, respectively. The first handle 603 is fixedly connected to the front end of the bidirectional threaded rod 601. The moving blocks 602 are symmetrically distributed on the bidirectional threaded rod 601. The internal threads of the two moving blocks 602 are in opposite directions. When working, rotating the first handle 603, in cooperation with the bidirectional threaded rod 601, can drive the moving blocks 602 to move. When the two moving blocks 602 move towards each other, the distance between the upper frame 3 and the lower frame 1 can be increased; conversely, the distance between the upper frame 3 and the lower frame 1 can be shortened.

[0022] The vertical frame 2 has a sliding groove 12 inside, and a slider 13 is slidably connected inside the sliding groove 12. The slider 13 is fixedly connected to the moving block 602. During operation, by setting the sliding groove 12 and the slider 13, the movement of the moving block 602 can be limited, so that the moving block 602 can move smoothly.

[0023] The transmission assembly 11 includes a bearing housing 1101, a transmission shaft 1102, a first bevel gear 1103, and a second bevel gear 1104. The bearing housing 1101 is fixedly connected to the rear end of the vertical frame 2. The transmission shaft 1102 is rotatably connected inside the bearing housing 1101. The second bevel gear 1104 is fixedly connected to both ends of the transmission shaft 1102. The front end of the second bevel gear 1104 meshes with the first bevel gear 1103. The first bevel gear 1103 is fixedly connected to the bidirectional threaded rod 601. During operation, as one side of the bidirectional threaded rod 601 rotates, the transmission shaft 1102, the first bevel gear 1103, and the second bevel gear 1104 can drive the other side of the bidirectional threaded rod 601 to rotate simultaneously. In this way, the two sides of the upper frame 3 and the lower frame 1 can be adjusted at the same time.

[0024] The connecting assembly 10 includes a connecting plate 1001, a plug-in socket 1002, and a plug-in block 1003. Plug-in sockets 1002 are fixedly connected to both sides of the lower frame 1. A plug-in block 1003 is inserted into the plug-in socket 1002. The plug-in block 1003 is fixedly connected to the fan 8. The connecting plate 1001 is fixedly connected to the lower end of the plug-in block 1003. During operation, the plug-in block 1003 on the fan 8 is aligned with the plug-in socket 1002, and the plug-in block 1003 can be inserted into the plug-in socket 1002, thereby achieving the purpose of initially installing the fan 8.

[0025] The limiting mechanism 9 includes a limiting rod 901, a moving rod 902, a transmission threaded rod 903, a second handle 904, a second transmission rod 905, a limiting rod 906, and a limiting hole 907. The limiting rod 901 is fixedly connected inside the lower frame 1. The moving rod 902 is slidably connected to the limiting rod 901. The end of the moving rod 902 away from the limiting rod 901 is threadedly connected to the transmission threaded rod 903. The transmission threaded rod 903 passes through the lower frame 1 and is rotatably connected to it. The end of the transmission threaded rod 903 is fixedly connected to the second handle 904. The second transmission rod 905 is rotatably connected to both sides of the moving rod 902. The end of the second transmission rod 905 away from the moving rod 902 is rotatably connected to the limiting rod 906. The lower end of the limiting rod 906 has an inclined surface. The upper surface of the connecting plate 1001 has an opening... There is a limiting hole 907, which corresponds to the limiting rod 906. During operation, after the fan 8 is initially installed, the second handle 904 is rotated. With the cooperation of the transmission threaded rod 903, the moving rod 902 can be moved on the limiting rod 901. Then, with the cooperation of the second transmission rod 905, the limiting rod 906 can be inserted into the limiting hole 907, thereby limiting the connecting plate 1001. This allows the fan 8 to be stably connected to the lower frame 1, enabling the simultaneous installation of multiple fans 8 and improving the installation efficiency of the fan 8. When it is necessary to disassemble the fan 8, the second arm is rotated in the opposite direction. This causes the limiting rod 906 to disengage from the limiting hole 907, thereby releasing the limitation on the connecting plate 1001, making it easy to disassemble the fan 8.

[0026] A limiting groove 15 is fixedly connected to the inner wall of the lower frame 1. A limiting block 16 is slidably connected inside the limiting groove 15. The limiting block 16 is fixedly connected to the limiting rod 906. During operation, by setting the limiting groove 15 and the limiting block 16, the movement of the limiting rod 906 can be limited, so that the limiting rod 906 can move vertically smoothly.

[0027] The upper frame 3 has four lifting lugs 4 fixedly connected to both sides of its upper end. During operation, the lifting lugs 4 facilitate the hoisting of the device.
