Description

TECHNICAL FIELD

[0001] The present application relates to the field of support devices, in particular to a novel support device for the body of a dry-type transformer. BACKGROUND

[0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, wharves, CNC mechanical equipment and other places. Simply put, a dry-type transformer refers to a transformer whose core and winding are not immersed in insulating oil.

[0003] For example, Chinese Patent Publication No. CN114678188B discloses a transformer support device for a utility pole, which includes support frames for supporting the transformer. The number of support frames is two, and the two support frames are connected by a crossbeam. The support frames and the crossbeam can be adjusted in sliding mode. The lower end of the support frame is connected to a bracket, which is connected to the utility pole by a chain. The lower ends of the two support frames are connected by a hanger, which is used to fix a distribution box.

[0004] The existing technology has the following problems: The above device improves the safety of regional operation, provides a support height for transformer installation, and makes use more safe. However, the fixed position between the support device and the utility pole is low, which facilitates the disassembly and assembly of construction personnel, reduces the difficulty and danger of disassembly and assembly. However, the above device is installed at the upper end of the utility pole, and the wind force is strong at high altitude. Therefore, the support assembly will bear more pressure due to the wind force. SUMMARY

[0007] Preferably, the bottom of the mounting plate is fixedly connected to a slide rail, and the movable plate is slidably connected to the outer wall of the slide rail.

[0008] Preferably, a spring is fixedly connected to the bottom of the mounting plate, and the bottom of the spring is movably connected to the movable plate.

[0009] Preferably, the support assembly includes a mounting rod, which is fixedly connected to the bottom of the mounting plate. An adjusting rod is fixedly connected to the bottom of the mounting rod, and an adjusting column is slidably connected to the outside of the adjusting rod. A snap-fit ​​seat is fixedly connected to the bottom of the adjusting column, and adjusting holes are provided on the outer walls of both the adjusting rod and the adjusting column.

[0010] Preferably, the upper end of the card holder is equipped with a clamping component, and the outer wall of the air-breaking plate is equipped with a closing component.

[0011] Preferably, the clamping assembly includes a rectangular frame, which is fixedly sleeved on the outer wall of the mounting shaft. The outer wall of the rectangular frame has a sliding groove, and a U-shaped rod is slidably connected inside the sliding groove. The outer wall of the adjusting column is fixedly connected to a limiting block, and the limiting block has a through-hole in the middle. A moving rod is slidably connected inside the through-hole. A stop block and an arc plate are fixedly connected to both ends of the moving rod, respectively. A fixing block is fixedly connected to the upper end of the locking seat, and a through hole is opened in the middle of the fixing block. A movable rod is slidably connected inside the through hole. A moving block is fixedly connected to one end of the movable rod, and a roller is provided at the other end of the movable rod.

[0012] Preferably, the clamping plate is provided with protrusions to increase friction.

[0013] Preferably, a portion of the side of the abutment that contacts the roller is configured as an inclined surface.

[0016] The advantages of this application are: (1) Through the design of blades and centrifugal balls, this application can automatically adjust the angle of the wind-breaking plate according to the change of wind force. When the wind force is too strong, the device will start automatically. The wind force is weakened by the adjustment of the wind-breaking plate, avoiding the impact of excessive wind force on the dry-type transformer and protecting the equipment. The change of wind force reduces the pressure on the support components by adjusting the state of the wind-breaking plate, avoiding the problem of equipment being damaged due to excessive force when the wind force is too strong.

[0017] (2) Through the design of the clamping components and the C-shaped rod, this application enables the clamping device to automatically adjust under strong winds. In strong winds, the clamping plate contacts the surface of the utility pole, which can effectively disperse external forces, reduce the pressure on the clamping seat, ensure the tightness between the clamping seat and the utility pole, prevent loosening or instability caused by excessive wind force, and further enhance the stability of the device.

[0018] (3) This application achieves ventilation under normal working conditions by setting up a closed component and the cooperative design of the air-breaking plate and the closed plate, thus avoiding affecting the heat dissipation of the transformer; when the wind force is too strong, the closed plate automatically closes the ventilation opening, effectively ensuring the air-breaking effect and improving the safety and stability of the equipment.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Example 1, please refer to Figures 1-8This embodiment provides a novel support device for the body of a dry-type transformer, including a mounting plate 1; a support assembly 2, which is assembled at the bottom of the mounting plate 1; a mounting shaft 31 is rotatably connected to the bottom of the mounting plate 1, and a blade 32 is fixedly connected to the outer wall of the mounting shaft 31. The blade 32 is used to drive the mounting shaft 31 to rotate by wind power. A centrifugal rod 33 is hinged to the outer wall of the mounting shaft 31, and a centrifugal ball 34 is fixedly connected to the other end of the centrifugal rod 33. A connecting rod A35 is hinged to the inner side of the centrifugal ball 34, and the other end of the connecting rod A35 is rotatably connected to a movable bearing seat through a bearing seat. The upper end of the movable plate 36 is hinged to a connecting rod B37, and the other end of the connecting rod B37 is hinged to a moving plate 38. A connecting plate 39 is fixedly connected to the side of the mounting plate 1. A rotating rod 310 is rotatably connected to the upper end of the connecting plate 39. A movable sleeve 311 is rotatably fitted on the outer wall of the rotating rod 310. Air-breaking plates 312 are fixedly connected to the outer walls of the two movable sleeves 311 respectively. A connecting rod C313 is rotatably connected to the upper end of the moving plate 38. A connecting shaft 314 is rotatably connected to the upper end of the connecting rod C313. The upper end of the connecting shaft 314 is rotatably connected to the air-breaking plate 312. A slide rail 315 is fixedly connected to the bottom of the mounting plate 1. The moving plate 38 is slidably connected to the outer wall of the slide rail 315. The stability of the moving plate 38 can be ensured by setting the slide rail 315. A spring 316 is fixedly connected to the bottom of the mounting plate 1. The bottom of the spring 316 is movably connected to the movable plate 36. By setting the spring 316, the movable plate 36 can be kept at a certain height when there is no wind, and it can also be reset when the wind speed decreases. The support assembly 2 includes a mounting rod 21, which is fixedly connected to the bottom of the mounting plate 1. An adjusting rod 22 is fixedly connected to the bottom of the mounting rod 21. An adjusting column 23 is slidably connected to the outside of the adjusting rod 22. A locking seat 24 is fixedly connected to the bottom of the adjusting column 23. Adjustment holes are opened on the outer walls of both the adjusting rod 22 and the adjusting column 23. A clamping assembly 4 is installed at the upper end of the locking seat 24, and a closing assembly 5 is installed on the outer wall of the windbreak plate 312.

[0028] In use, firstly, the two locking seats 24 are fitted onto the outer wall of the utility pole, and then the two locking seats 24 are fixed together with bolts. Next, the mounting rod 21 is fixed to the bottom of the mounting plate 1, and the adjusting rod 22 is slid inside the adjusting column 23 to adjust to a suitable height. Then, the adjusting rod 22 is fixed together with the adjusting column 23. Since this device is set at the moving height, the wind force at high altitudes is relatively large. When encountering excessive wind and humidity, it will drive the mounting shaft 31 to rotate by blowing the blade 32. When the rotation speed of the mounting shaft 31 reaches a certain level, the centrifugal rod 33 and the centrifugal ball 34 will expand outward under the action of centrifugal force. When the centrifugal ball 34 is opened, it will pull the movable plate 36 to the bottom through the inner hinged connecting rod A35. When the movable plate 36 moves to the bottom, it will pull the moving plate 38 to the center on the outer wall of the slide rail 315 through the connecting rod B37 at its upper end. Then the moving plate 38 can pull the wind-breaking plate 312 to rotate inward around the rotating rod 310 with the movable sleeve 311 through the connecting rod C313 and the connecting shaft 314. This can switch the two wind-breaking plates 312 from a parallel state to a V-shaped state, thereby weakening the strong wind and reducing its impact on the transformer, while also reducing the pressure on the support assembly 2.

[0029] Example 2, please refer to Figures 1-8 Based on implementation 1, the clamping assembly 4 includes a rectangular frame 41, which is fixedly sleeved on the outer wall of the mounting shaft 31. The outer wall of the rectangular frame 41 has a sliding groove 42, and a U-shaped rod 43 is slidably connected inside the sliding groove 42. The outer wall of the adjusting column 23 is fixedly connected to a limiting block, and the limiting block has a through opening in the middle. The through opening is slidably connected to a moving rod 44. The two ends of the moving rod 44 are respectively fixedly connected to a stop block 45 and an arc plate 414. The upper end of the locking seat 24 is fixedly connected to a fixing block 46, and the middle of the fixing block 46 has a through hole. The through hole is slidably connected to a movable rod 47. One end of the movable rod 47 is fixedly connected to a moving block 49, and the other end of the movable rod 47 is provided with a roller 48. The upper end of the moving block 49 is hinged to a connecting rod D410, and the other end of the connecting rod D410 is hinged to a clamping plate 412. The bottom of the clamping plate 412 is rotatably connected to the locking seat 24 through a pin. The clamping plate 412 is provided with protrusions 413 to increase friction. One part of the side of the abutment 45 that contacts the roller 48 is set as an inclined surface. The inclined surface design of the abutment 45 can enable the roller 48 to move vertically when the abutment 45 moves.

[0030] In use, when the centrifugal rod 33 expands outward, the incised rod 43 is tightly fitted to the outer side of the centrifugal rod 33. Therefore, when the centrifugal rod 33 expands outward, it pushes the incised rod 43 to slide outward inside the slide groove 42. Consequently, the arc-shaped plate 414 located outside the incised rod 43 is pushed outward, which in turn pushes the moving rod 44 to move outward. The abutment block 45 at the other end of the moving rod 44 then moves in the same direction, causing the surface of the roller 48 in contact with the abutment block 45 to change from a plane to an inclined plane, thus... As the movable rod 47 moves toward the center of the locking seat 24, the movable block 49 at the other end of the movable rod 47 will also move in the same direction. This allows the connecting rod D410 to push the clamping plate 412 to rotate around the hinge point with the locking seat 24. This allows the side of the clamping plate 412 away from the connecting rod D410 to move closer to the outer wall of the utility pole until the protrusion 413 on the inner side of the clamping plate 412 contacts the utility pole. In windy weather, the contact between the clamping plate 412 and the surface of the utility pole prevents the locking seat 24 from bearing excessive force.

[0031] Example 3, please refer to Figures 1-8 Based on implementation 1, the closing component 5 includes a vent 51, which is located in the middle of the air-breaking plate 312. The inner wall of the vent 51 is rotatably connected to a rotating shaft 52, and the outer wall of the rotating shaft 52 is fixedly connected to a closing plate 53. The bottom of the rotating shaft 52 passes through the air-breaking plate 312 and is fixedly connected to a gear 54. The outer wall of the connecting plate 39 is fixedly connected to a connecting block 55, and the upper end of the connecting block 55 is fixedly connected to a semi-ring toothed plate 56. The gear 54 is located inside the semi-ring toothed plate 56 and meshes with it.

[0032] In use, when the air-breaking plate 312 rotates inward, the rotating shaft 52 connected inside the ventilation opening 51 in its middle will also rotate around the rotating rod 310. The gear 54 at the bottom of the rotating shaft 52 will also rotate around the rotating rod 310. Since the gear 54 meshes with the semi-ring toothed plate 56 and the semi-ring toothed plate 56 is always stationary, the gear 54 will rotate on its own axis while rotating around the rotating rod 310. This will drive the closing plate 53 to rotate on its own axis through the rotating shaft 52. That is, when the air-breaking plate 312 rotates inward, the closing plate 53 rotates outward. When the rotation process of the air-breaking plate 312 ends, the closing plate 53 can just close the ventilation opening 51. Thus, under normal conditions, the ventilation opening 51 is open to avoid affecting the heat dissipation of the transformer, and under air-breaking conditions, the ventilation opening 51 is closed, thereby ensuring the air-breaking effect.

[0033] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
