Description

Technical Field

[0001] This utility model relates to the field of power transformer technology, and in particular to a power transformer core clamping device. Background Technology

[0002] A power transformer is a static electrical device that uses the principle of electromagnetic induction to convert electrical energy from one voltage level to another in a power system. The core clamping device of a power transformer is an important component used to fix the transformer core, ensure its stability during operation, reduce vibration and noise, and ensure the integrity of the core's magnetic circuit.

[0003] Currently, the clamping device for the core of a power transformer typically uses bolts to fix the clamping plate. This method requires a lot of time to install and remove the clamping plate, thus reducing operational efficiency and affecting the user experience. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the installation and removal process of the clamping plate is relatively cumbersome, which will result in poor operation efficiency. Therefore, we propose a power transformer core clamping device.

[0005] To achieve the above objectives, this application adopts the following technical solution: a power transformer core clamping device, comprising a mounting base plate, a transformer core body mounted on the top of the mounting base plate, a clamping plate sleeved on the surface of the transformer core body, mounting plates mounted on the front and rear ends of the clamping plate, two fixing rods fixedly connected to the top of the mounting base plate, a fixing block fixedly connected to the top of the fixing rods, two slots formed on the surface of the mounting plate, a buckle slidably connected inside the fixing block, a fixing plate fixedly connected inside the fixing block, spring springs fixedly connected to both sides of the fixing plate, the spring springs being fixedly connected to the buckles on the side closer to the buckles, sliding sleeves mounted on both sides of the fixing block, sliding grooves formed inside both sides of the fixing block and the sliding sleeves, sliding rods slidably connected inside the sliding grooves, and a push-pull plate fixedly connected to the side of the sliding rod away from the sliding sleeves.

[0006] Preferably, an energy storage spring is sleeved on the surface of the sliding rod, and the two sides of the energy storage spring are fixedly connected to the sliding sleeve and the push-pull plate, respectively.

[0007] Preferably, the front and rear ends of the sliding sleeve are provided with first sliding grooves, and the front and rear ends of the sliding rod are fixedly connected with first sliders, and the interior of the first sliding groove is slidably connected to the first slider.

[0008] Preferably, the front and rear ends of the fixing block are provided with second sliding grooves, and the front and rear ends of the buckle are fixedly connected with second sliders, and the interior of the second sliding groove is slidably connected to the second sliders.

[0009] Preferably, the end of the buckle is rounded, and two rubber contact plates are installed at the top of the mounting plate.

[0010] Preferably, rubber plates are installed at both the front and rear ends inside the clamping plate, and the rubber plates are slidably connected to the surface of the transformer core body.

[0011] Preferably, heat dissipation fins are installed at both the front and rear ends of the clamping plate, and the number of heat dissipation fins is several and evenly distributed at the front and rear ends of the clamping plate.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, when workers need to clamp the transformer core, they slide the clamping plate into the transformer core and align the slot with the buckle. After buckling, the spring force is released, causing the buckle to securely engage inside the slot, thus achieving rapid clamping of the transformer core. When the clamping plate needs to be removed, the push-pull plate is pressed inward, causing the sliding rod to abut the buckle, disengaging the buckle from the slot. At this point, the clamping plate can be removed from the transformer core. This design allows for convenient clamping of the transformer core, making the clamping process simpler and faster for workers. It also effectively reduces operation time during disassembly and maintenance, significantly improving operational efficiency. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figures 1-5 As shown, this utility model provides a technical solution: a power transformer core clamping device, including a mounting base plate 1, a transformer core body 2 mounted on the top of the mounting base plate 1, a clamping plate 3 sleeved on the surface of the transformer core body 2, mounting plates 4 mounted on the front and rear ends of the clamping plate 3, two fixing rods 5 fixedly connected to the top of the mounting base plate 1, a fixing block 6 fixedly connected to the top of the fixing rods 5, two slots 7 formed on the surface of the mounting plate 4, a buckle 8 slidably connected inside the fixing block 6, a fixing plate 9 fixedly connected inside the fixing block 6, spring springs 10 fixedly connected to both sides of the fixing plate 9, the side of the spring spring 10 near the buckle 8 fixedly connected to the buckle 8, sliding sleeves 11 mounted on both sides of the fixing block 6, sliding grooves 12 formed inside both sides of the fixing block 6 and the sliding sleeves 11, sliding rods 13 slidably connected inside the sliding grooves 12, the sliding rods 13 being away from the sliding sleeves 11. A push-pull plate 14 is fixedly connected to one side of the moving sleeve 11. When the operator needs to clamp the transformer core body 2, the clamping plate 3 is slid into the transformer core body 2 and the slot 7 is aligned with the buckle 8. After the buckle is engaged, the elastic force of the spring spring 10 is released, causing the buckle 8 to be firmly engaged inside the slot 7, thereby achieving quick clamping of the transformer core body 2. When the clamping plate 3 needs to be removed, the push-pull plate 14 is pressed inward, causing the sliding rod 13 to abut against the buckle 8, so that the buckle 8 is disengaged from the slot 7. At this time, the clamping plate 3 can be removed from the transformer core body 2. By setting the clamping plate 3 to easily clamp the transformer core body 2, the operator can operate more conveniently and quickly when clamping the transformer core body 2, and can effectively reduce the operation time when disassembly and maintenance are required, thereby significantly improving the operation efficiency.

[0022] Reference Figure 5As shown in this embodiment: an energy storage spring 15 is sleeved on the surface of the sliding rod 13. The two sides of the energy storage spring 15 are fixedly connected to the sliding sleeve 11 and the push-pull plate 14, respectively. With the setting of the energy storage spring 15, when the push-pull plate 14 is pressed and the sliding rod 13 is moved, the push-pull plate 14 is released. At this time, the elastic force stored in the energy storage spring 15 is released, which causes the sliding rod 13 to quickly return to the initial pressed position, thereby achieving the rapid reset of the sliding rod 13 after being pressed.

[0023] Reference Figure 5 As shown in this embodiment: the front and rear ends of the sliding sleeve 11 are provided with first sliding grooves 16, and the front and rear ends of the sliding rod 13 are fixedly connected with first sliders 17. The interior of the first sliding groove 16 is slidably connected to the first slider 17. Through the setting of the first sliding groove 16 and the first slider 17, the sliding rod 13 can form a stable limiting effect when sliding inside the sliding sleeve 11, so that the sliding rod 13 will not move excessively during the movement, thereby effectively improving the stability when the buckle 8 and the slot 7 are disengaged.

[0024] Reference Figure 5 As shown in this embodiment: the front and rear ends of the fixed block 6 are provided with second sliding grooves 18, and the front and rear ends of the buckle 8 are fixedly connected with second sliders 19. The interior of the second sliding groove 18 is slidably connected with the second slider 19. Through the setting of the second sliding groove 18 and the second slider 19, the buckle 8 can form a stable guiding effect when sliding inside the fixed block 6, so that the buckle 8 will not be deviated during the process of engaging with the buckle groove 7, effectively ensuring the stability of the clamping plate 3 during installation.

[0025] Reference Figure 4 and Figure 5 As shown in this embodiment: the end of the buckle 8 is provided with a rounded corner 20, and two rubber contact plates 21 are installed on the top of the mounting plate 4. By setting the rounded corner 20 and the rubber contact plates 21, the buckle 8 and the slot 7 can have less friction during the snapping process, and it is not easy to shake after snapping, which effectively improves the stability of the clamping plate 3 after installation.

[0026] Reference Figure 2 As shown in this embodiment: rubber plates 22 are installed at both the front and rear ends of the clamping plate 3. The rubber plates 22 are slidably connected to the surface of the transformer core body 2. By setting the rubber plates 22, the clamping plate 3 can have greater friction with the surface of the transformer core body 2 during the installation process, thereby making the clamping plate 3 more stable and having a limiting effect during the installation process, effectively improving the clamping effect.

[0027] Reference Figure 2As shown in this embodiment, heat dissipation fins 23 are installed at both the front and rear ends of the clamping plate 3. The number of heat dissipation fins 23 is several and they are evenly distributed at the front and rear ends of the clamping plate 3. By setting the heat dissipation fins 23, the clamping plate 3 can effectively improve the heat dissipation effect of the device when clamping the transformer core body 2, so that the heat generated by the transformer core body 2 during operation can be dissipated in time, avoiding equipment failure or performance degradation due to excessive temperature.

[0028] Working principle: When the operator needs to clamp the transformer core body 2, the clamping plate 3 is slid into the transformer core body 2, and the slot 7 is aligned with the buckle 8 and snapped in. After snapping, the spring force of the spring spring 10 is released, causing the buckle 8 to be firmly engaged inside the slot 7, thereby achieving rapid clamping of the transformer core body 2. When it is necessary to remove the clamping plate 3, the push-pull plate 14 is pressed inward, causing the sliding rod 13 to abut against the buckle 8, so that the buckle 8 is disengaged from the slot 7. At this time, the clamping plate 3 can be removed from the transformer core body 2. The clamping plate 3 can be used to conveniently clamp the transformer core body 2. The clamping mechanism for the core body 2 makes clamping the transformer core body 2 easier and faster for operators, and effectively reduces operation time when disassembly and maintenance are required, thus significantly improving operational efficiency. Through the energy storage spring 15, when the push-pull plate 14 is pressed, causing the sliding rod 13 to move, and then the push-pull plate 14 is released, the stored elastic force of the energy storage spring 15 is released, causing the sliding rod 13 to quickly return to its initial pressed position, thus achieving rapid reset of the sliding rod 13 after pressing. The first groove 16 and the first slider 17 allow the sliding rod 13 to move within the sliding sleeve 1... The internal sliding mechanism of the first sliding block 13 creates a stable limiting effect, preventing excessive movement of the sliding rod 13 during its movement. This effectively improves the stability when the buckle 8 and the slot 7 are disengaged. The second sliding groove 18 and the second slider 19 provide a stable guiding effect when the buckle 8 slides inside the fixing block 6, preventing displacement during engagement with the slot 7 and ensuring the stability of the clamping plate 3 during installation. The rounded corner 20 and the rubber contact plate 21 reduce friction during engagement, minimizing friction after engagement. The rubber plate 22 allows for greater friction between the clamping plate 3 and the surface of the transformer core 2 during installation, resulting in a more stable and limiting clamping effect. The heat dissipation fins 23 further enhance the heat dissipation of the device when clamping the transformer core 2, preventing overheating and thus avoiding equipment failure or performance degradation.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
