Description

Technical Field

[0001] This utility model relates to the field of transformer equipment technology, specifically to an oil-immersed three-dimensional wound core transformer with an angle adjustment structure. Background Technology

[0002] Oil-immersed transformers with three-dimensional wound cores are widely used in power distribution fields such as rural and urban power grids. These transformers typically employ a cylindrical structure with copper foil windings around the shaft, and the high-voltage winding uses a multi-layer cylindrical structure, resulting in a balanced ampere-turn distribution, low leakage flux, high mechanical strength, and strong short-circuit withstand capability. However, existing oil-immersed three-dimensional wound core transformers have a fixed installation direction, making adjustment cumbersome and inconvenient during installation. Therefore, we need to propose an oil-immersed three-dimensional wound core transformer with an angle-adjustable structure. Utility Model Content

[0003] The purpose of this invention is to provide an oil-immersed three-dimensional wound core transformer with an angle-adjustable structure, which allows for convenient adjustment and control of the transformer in different directions during installation, thereby improving the efficiency of transformer installation and solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides: an oil-immersed three-dimensional wound core transformer with an angle-adjustable structure, comprising a transformer body, a mounting frame installed at the bottom of the transformer body, and a bearing base; an annular slider is rotatably mounted on the top of the bearing base via an annular guide rail, a mounting frame is mounted on the surface of the annular slider, a fixing frame is installed inside the mounting frame, and an assembly positioning component for mounting and fixing the mounting frame is provided on the surface of the fixing frame; the mounting frame is movably mounted on the top of the annular slider, and a locking rod is connected to the surface of the mounting frame via a fixing plate, with a fixing plate connected to the bottom end of the locking rod.

[0005] Preferably, the assembly positioning component includes: a self-locking adjusting screw rotatably mounted on the surface of the fixed frame, and a driven bevel gear connected to the surface of the self-locking adjusting screw; wherein, a movable sleeve is movably mounted on the surface of the self-locking adjusting screw, and an assembly insert is connected to the end of the movable sleeve.

[0006] Preferably, the mounting frame has guide holes at both ends, and the surface of the movable sleeve is slidably connected to the inner wall of the guide holes.

[0007] Preferably, an adjusting rod is rotatably mounted on one side of the self-locking adjusting screw on the surface of the mounting frame, and a transmission bevel gear that meshes with the driven bevel gear is mounted on one end of the adjusting rod.

[0008] Preferably, the mounting bracket has an assembly hole on its surface, the assembly block is movably inserted into the inner wall of the assembly hole, a fixing plate is mounted on the side of the mounting bracket, and the locking rod is threaded onto the surface of the fixing plate.

[0009] Preferably, the annular guide rail is fixedly installed on the top of the support base, and the bottom of the annular slider is rotatably engaged with the surface of the annular guide rail.

[0010] Preferably, a mounting plate is mounted on the surface of the annular slider, and the mounting frame is mounted on top of the mounting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model utilizes a combination of a mounting bracket, a support base, an annular slider, a mounting frame, and assembly positioning components. An adjusting rod rotates a transmission bevel gear, which in turn drives a movable sleeve equipped with a driven bevel gear. This allows the movable sleeve and assembly insert to be inserted into the assembly hole, precisely locking the mounting bracket's position and preventing displacement or loosening of the transformer during operation, ensuring long-term stable operation. The rotational cooperation between the annular guide rail and the annular slider allows the transformer body to be rotated horizontally, facilitating adjustments to the transformer's orientation according to actual installation needs, improving installation flexibility and applicability. After adjustment, a locking rod controls the position of the fixing plate, pressing it firmly against the top of the support base. This further ensures the stability of the connection between the transformer body and the support base and locks the transformer body's orientation, guaranteeing structural stability and further improving transformer installation efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides: an oil-immersed three-dimensional wound core transformer with an angle adjustment structure, including a transformer body 1, a mounting frame 2 installed at the bottom of the transformer body 1, and a bearing base 7; an annular slider 9 is rotatably mounted on the top of the bearing base 7 via an annular guide rail 8, a mounting frame 11 is mounted on the surface of the annular slider 9, a fixing frame 13 is installed inside the mounting frame 11, and an assembly positioning component for mounting and fixing the mounting frame 2 is provided on the surface of the fixing frame 13; the mounting frame 2 is movably mounted on the top of the annular slider 9, and a locking rod 4 is connected to the surface of the mounting frame 2 via a fixing plate 3, and a fixing plate 5 is connected to the bottom end of the locking rod 4.

[0020] It is worth noting that, through the coordinated arrangement of the mounting bracket 2, the bearing base 7, the annular slider 9, the mounting frame 11, and the assembly positioning component structure, the transformer body can be rotated 360° in the horizontal plane during installation. This facilitates adjusting the transformer's orientation according to actual installation needs, improving installation flexibility and applicability, and further enhancing the efficiency of transformer installation.

[0021] Specifically, the assembly positioning component includes: a self-locking adjusting screw 14 rotatably mounted on the surface of the fixed frame 13, and a driven bevel gear 15 connected to the surface of the self-locking adjusting screw 14; wherein, a movable sleeve 16 is movably mounted on the surface of the self-locking adjusting screw 14, and an assembly insert 17 is connected to the end of the movable sleeve 16. Guide holes 12 are provided at both ends of the mounting frame 11, and the surface of the movable sleeve 16 is slidably connected to the inner wall of the guide hole 12.

[0022] In addition, the self-locking adjusting screw 14 is a structure that drives the moving sleeve 16, so that the moving sleeve 16 drives the assembly block 17 to move inside the guide hole 12, and inserts the assembly block 17 into the assembly hole 6 of the mounting bracket 2 to fix the connection between the transformer body 1 and the annular slider 9.

[0023] An adjusting rod 18 is rotatably mounted on one side of the self-locking adjusting screw 14 on the surface of the mounting frame 11. One end of the adjusting rod 18 is fitted with a transmission bevel gear 19 that meshes with the driven bevel gear 15. The surface of the mounting bracket 2 has an assembly hole 6, and an assembly insert 17 is movably inserted into the inner wall of the assembly hole 6. A fixing plate 3 is mounted on the side of the mounting bracket 2, and a locking rod 4 is threaded onto the surface of the fixing plate 3.

[0024] The adjusting rod 18 rotates the transmission bevel gear 19, which in turn drives the driven bevel gear 15, causing the self-locking adjusting screw 14 to rotate and control the movement of the moving sleeve 16. The self-locking adjusting screw 14 can automatically maintain a locked state, preventing reverse movement when the drive stops without additional braking devices, thus ensuring the stability of the structure. The locking rod 4 controls the fixed plate 5, pressing it against the top of the bearing base 7 to prevent the annular slider 9 from moving on the annular guide rail 8 after the direction is adjusted.

[0025] Furthermore, the annular guide rail 8 is fixedly installed on the top of the support base 7, and the bottom of the annular slider 9 is rotatably engaged with the surface of the annular guide rail 8. A mounting plate 10 is mounted on the surface of the annular slider 9, and a mounting frame 11 is mounted on top of the mounting plate 10. An annular groove is formed at the bottom of the inner wall of the annular guide rail 8, and a protruding ring that mates with the annular groove is provided on the bottom surface of the annular slider 9. The mounting plate 10 is the connecting structure between the annular slider 9 and the mounting frame 11.

[0026] The transmission bevel gear 19 can be rotated via the adjusting rod 18, which in turn drives the driven bevel gear 15, causing the self-locking adjusting screw 14 to rotate. This allows the movable sleeve 16 and the assembly block 17 connected to the surface of the self-locking adjusting screw 14 to be inserted into the assembly hole 6, precisely locking the position of the mounting bracket and preventing displacement or loosening of the transformer during operation, ensuring long-term stable operation of the equipment. Simultaneously, automatic locking after adjustment prevents displacement or loosening due to vibration or external force, further enhancing the reliability and safety of the equipment. Through the rotational cooperation of the annular guide rail and the annular slider, the transformer body can be rotated 360° in the horizontal plane for easy adjustment. The transformer's orientation can be adjusted according to actual installation needs to improve installation flexibility and applicability; while ensuring rotational function, it provides stable support; after adjustment, the position of the fixing plate 5 is controlled by the locking rod 4, pressing and fixing the fixing plate 5 to the top of the bearing base 7, and cooperating with the assembly plug 17 to be inserted into the assembly hole 6 of the mounting bracket 2, further ensuring the stability of the connection between the transformer body 1 and the bearing base 7, and locking and fixing the orientation of the transformer body 1; ensuring structural stability and further improving the efficiency of transformer installation; at the same time, it can be widely used in three-dimensional wound core transformers of different specifications, with strong compatibility, meeting the installation requirements of diverse scenarios.
