Description

Technical Field

[0001] This utility model relates to the field of grounding transformer technology, specifically a grounding transformer with a mounting base. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Its main components are the primary coil, secondary coil, and iron core. Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization.

[0003] Chinese patent application CN202222605890.1 discloses a transformer with a mounting base, including a transformer device and a support base. The transformer device is fixedly mounted on the upper surface of the support base. A transformer unit is fixedly installed inside the transformer device. First snap-fit ​​plates are symmetrically welded to both sides of the bottom surface of the transformer unit. First connecting holes are evenly distributed through the sides of the first snap-fit ​​plates. A crossarm is fixedly connected to the bottom surface of the first snap-fit ​​plates. Fastening bolts are evenly and symmetrically threaded onto the outer surfaces of the two ends of the crossarm. Second connecting holes are evenly distributed on the sides of the crossarm, and threaded rods are inserted into the interior of the second connecting holes. Heat dissipation fins are evenly welded to the outside of the transformer unit. Although this utility model facilitates the adaptation and support of different transformer units by installing a support base at the bottom of the transformer unit, and allows for adjustment of the installation dimensions of the transformer unit's bottom according to the installation environment, this setup requires tightening the fastening bolts. Furthermore, when there are many bolts, workers need to constantly change their working positions when tightening bolts in different locations, increasing the difficulty of the work and posing safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide a grounding transformer with a mounting base to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a grounding transformer with a mounting base, including a base plate and a transformer. Sliding grooves are respectively opened at both ends of the base plate, and a fixing frame is fixedly connected to the outer wall of the base plate.

[0007] A movable frame is slidably connected to the inner wall of the sliding groove, and a connecting plate is rotatably connected between one end of the movable frame and the bottom of the transformer.

[0008] One end of both the movable frame and the fixed frame is set as an arc surface, and the movable frame and the fixed frame are used to clamp the utility pole;

[0009] A drive assembly is installed on the lower surface of the base plate. Rollers are installed at both ends of the drive assembly. An arc-shaped concave surface is provided on the outer wall of the roller, and the arc-shaped concave surface fits into the outer wall of the utility pole.

[0010] The purpose of the above setup is to adjust the rollers through the drive assembly so that the concave surface of the rollers moves close to the outer wall of the utility pole. At this time, the base plate and the transformer are between the two utility poles. When the base plate moves from top to bottom between the two utility poles, when the base plate falls to a certain height, the drive assembly adjusts the two rollers again at the same time. Due to the friction, the two rollers are stuck between the two utility poles.

[0011] The transformer is hoisted by rotating it to the movable frame via a connecting plate. After connection, as the transformer descends, it pushes the connecting plate and the movable frame. One end of both the movable and fixed frames is curved. The movement of the movable frame, in conjunction with the fixed frame, can be used to quickly clamp utility poles of different thicknesses.

[0012] Furthermore, the drive assembly includes a screw, a dual-axis motor, and a sliding block. The dual-axis motor is mounted on the lower surface of the base plate, the two screws are respectively mounted on the output shaft of the dual-axis motor, the sliding blocks are respectively slidably connected to the moving slots, and the screws pass through the sliding blocks and are threadedly connected.

[0013] The purpose of the above setup is that when the dual-axis motor starts, the output shaft of the dual-axis motor drives the screw to rotate. Since the screw passes through the sliding block and is threadedly connected, and the sliding block is slidably connected to the moving slot, when the screw rotates, the sliding block will move linearly along the screw.

[0014] The roller is rotatably connected to the bottom of the sliding block and is used to roll on the outer wall of the utility pole.

[0015] Furthermore, a plurality of connecting blocks are fixedly connected to the upper surface of the base plate, and folded aluminum plates are slidably connected to the outer wall of the connecting blocks;

[0016] The purpose of the above arrangement is to use the folded aluminum plate for heat conduction in the transformer.

[0017] Furthermore, the outer wall of the folded aluminum plate is provided with several V-shaped grooves;

[0018] The purpose of the above arrangement is to allow the transformer to be compressed and contracted when it descends to different heights above the base plate.

[0019] Furthermore, a through groove is provided in the middle of the folded aluminum plate;

[0020] The purpose of the above arrangement is to allow the heat on the folded aluminum plate to exchange with the air when the airflow passes through the slots of the folded aluminum plate, thereby enhancing the heat dissipation effect of the transformer.

[0021] This utility model has the following beneficial effects:

[0022] (1) This utility model uses a movable frame to hoist the transformer. The transformer is rotatably connected to the movable frame via a connecting plate. After connection, as the transformer descends, it pushes the connecting plate and the movable frame. One end of both the movable frame and the fixed frame is set as an arc surface. The movement of the movable frame, in conjunction with the fixed frame, can be used to quickly clamp poles of different thicknesses. Compared with the existing installation and fixing structure, the clamping is more convenient and has better adaptability.

[0023] (2) By setting up a folded aluminum plate, when the airflow passes through the through groove of the folded aluminum plate, the heat on the folded aluminum plate exchanges with the air, thereby enhancing the heat dissipation effect of the transformer.

[0024] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0035] 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.

[0036] Please see Figure 1 - Figure 7 As shown, this utility model is a grounding transformer with a mounting base, including a base plate 1 and a transformer 2. Sliding grooves 102 are respectively opened at both ends of the base plate 1, and a fixing frame 101 is fixedly connected to the outer wall of the base plate 1.

[0037] A movable frame 3 is slidably connected to the inner wall of the sliding groove 102, and a connecting plate 7 is rotatably connected between one end of the movable frame 3 and the bottom of the transformer 2.

[0038] One end of both the movable frame 3 and the fixed frame 101 is set as an arc surface, and the movable frame 3 and the fixed frame 101 are used to clamp the utility pole;

[0039] A drive assembly 4 is installed on the lower surface of the base plate 1. Rollers 5 are installed at both ends of the drive assembly 4. An arc-shaped concave surface is provided on the outer wall of the roller 5, and the arc-shaped concave surface fits into the outer wall of the utility pole.

[0040] The purpose of the above setup is to adjust the rollers 5 by driving component 4 so that the arc-shaped concave surface of the rollers 5 moves close to the outer wall of the utility pole. At this time, the base plate 1 and the transformer 2 are between the two utility poles. When the base plate 1 moves from top to bottom between the two utility poles, when the base plate 1 falls to a certain height, the driving component 4 adjusts the two rollers 5 again at the same time. Due to the friction, the two rollers 5 are stuck between the two utility poles.

[0041] The transformer 2 is hoisted and rotated to the movable frame 3 via the connecting plate 7. After connection, as the transformer 2 descends, it pushes the connecting plate 7 and the movable frame 3. One end of both the movable frame 3 and the fixed frame 101 is set as an arc surface. The movement of the movable frame 3, in conjunction with the fixed frame 101, can be used to quickly clamp utility poles of different thicknesses.

[0042] The drive assembly 4 includes a screw 401, a dual-axis motor 402, and a sliding block 403. The dual-axis motor 402 is mounted on the lower surface of the base plate 1. The two screws 401 are respectively mounted on the output shaft of the dual-axis motor 402. The sliding blocks 403 are respectively slidably connected to the moving groove 103. The screw 401 passes through the sliding block 403 and is threadedly connected.

[0043] The purpose of the above setup is that when the dual-axis motor 402 starts, the output shaft of the dual-axis motor 402 drives the screw 401 to rotate. Since the screw 401 passes through the sliding block 403 and is threadedly connected, and the sliding block 403 is slidably connected to the moving groove 103, when the screw 401 rotates, the sliding block 403 will move linearly along the screw 401.

[0044] Roller 5 is rotatably connected to the bottom of sliding block 403, and roller 5 is used to roll on the outer wall of the utility pole.

[0045] Several connecting blocks are fixedly connected to the upper surface of the base plate 1, and folded aluminum plates 6 are slidably connected to the outer wall of the connecting blocks;

[0046] The purpose of the above arrangement is to use the folded aluminum plate 6 for heat conduction of the transformer 2.

[0047] Several V-shaped grooves are provided on the outer wall of the folded aluminum plate 6;

[0048] The purpose of the above arrangement is to allow the transformer 2 to be compressed and contracted when it descends to different heights above the base plate 1.

[0049] A through groove is provided in the middle of the folded aluminum plate 6;

[0050] The purpose of the above arrangement is that when the airflow passes through the slot of the folded aluminum plate 6, the heat on the folded aluminum plate 6 exchanges with the air, thereby enhancing the heat dissipation effect of the transformer 2.

[0051] In use, the dual-axis motor 402 is started, and the output shaft of the dual-axis motor 402 drives the screw 401 to rotate. Since the screw 401 passes through the sliding block 403 and is threadedly connected, and the sliding block 403 is slidably connected to the moving groove 103, when the screw 401 rotates, the sliding block 403 will move linearly along the screw 401, thereby adjusting the roller 5 so that the arc concave surface of the roller 5 moves close to the outer wall of the utility pole. At this time, the base plate 1 and the transformer 2 are between the two utility poles. When the base plate 1 moves from top to bottom between the two utility poles, when the base plate 1 falls to a certain height, the drive component 4 adjusts the two rollers 5 again at the same time. Due to the friction, the two rollers 5 are stuck between the two utility poles.

[0052] The transformer 2 is hoisted. The transformer 2 is rotatably connected to the movable frame 3 through the connecting plate 7. After the connection, as the transformer 2 descends, it pushes the connecting plate 7 and the movable frame 3. One end of the movable frame 3 and the fixed frame 101 are both set as arc surfaces. The movement of the movable frame 3, in conjunction with the fixed frame 101, can be used to quickly clamp utility poles of different thicknesses.

[0053] When the transformer 2 descends to different heights above the base plate 1, it can be squeezed and contracted by the transformer 2. When the airflow passes through the through slot of the folded aluminum plate 6, the heat on the folded aluminum plate 6 exchanges with the air, thereby enhancing the heat dissipation effect of the transformer 2.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
