Description

Technical Field

[0001] This utility model belongs to the field of ring main unit technology, specifically relating to a remote control operating mechanism for a ring main unit. Background Technology

[0002] A ring main unit (RMU) is a high-voltage switchgear assembly used in power systems, typically composed of load switches, fuses, disconnect switches, grounding switches, busbars, cable terminals, and other components. These components are installed within a closed metal cabinet or modular structure to form a complete power supply unit. RMUs are mainly used in medium-voltage power distribution networks to receive and distribute electrical energy, and to control, protect, and monitor circuits. When a circuit breaker fails, close-range manual operation poses significant safety hazards and can seriously endanger the personal safety of operators; therefore, remote operation using tools is necessary. Existing suction cup tools, however, rely on sealing performance for suction force. If the RMU surface is uneven or has small gaps, vacuum negative pressure alone is insufficient to completely eliminate these gaps, resulting in insufficient suction force and inability to stably adhere to uneven surfaces.

[0036] This embodiment provides a remote control operating mechanism for a ring main unit. Figure 1 This is a schematic diagram of the overall structure of a ring main unit remote control operating mechanism provided in this embodiment.

[0037] like Figure 1 As shown, the remote control operating mechanism of the ring main unit in this embodiment includes a support arm 1, an adjustment component 2, a suction cup component 3, and a pressing component 4. The suction cup component 3 is connected to the support arm 1 via the adjustment component 2. The adjustment component 2 can adjust the tilt angle of the suction cup component 3 in a first direction and a second direction. The pressing component 4 is vertically and flexibly mounted on the suction cup component 3. The pressing component 4 can press down on the suction cup component 3 to expel air between the suction cup component 3 and the cabinet surface.

[0038] In some examples, such as Figure 1 As shown, the support arm 1 is provided with a handle 12, which is located near the end of the support arm 1 furthest from the adjustment component 2. This arrangement facilitates the operator's grip and improves operational accuracy and stability. In this embodiment, there are two handles 12 on the support arm 1, located in different directions. This arrangement allows for more flexible gripping by the operator and is suitable for various working angles. However, it is understood that in other embodiments, the number and position of the handles 12 can be set according to actual needs, and this embodiment does not impose excessive restrictions on this.

[0039] In some examples, such as Figure 1 As shown, the support arm 1 is equipped with multiple control buttons 11, which are located near the end of the support arm 1 furthest from the adjustment component 2. These control buttons 11 are used to control the adjustment component 2, the suction cup component 3, and the clamping component 4, respectively, to facilitate flexible operation. However, it should be noted that in other embodiments, the adjustment component 2, the suction cup component 3, and the clamping component 4 can also be wirelessly controlled, with the control terminal located on the support arm 1 or designed separately from it.

[0040] The remote control operating mechanism for the ring main unit provided in this embodiment includes a support arm 1, an adjustment component 2, a suction cup component 3, and a pressing component 4. The adjustment component 2 can adjust the tilt angle of the suction cup component 3 in the first and second directions, allowing the suction cup component 3 to fit the cabinet surface at the optimal angle, improving the adaptability of the suction cup component 3 to the cabinet surface and enhancing the adsorption effect. The pressing component 4 can press down on the suction cup component 3 to expel air between the suction cup component 3 and the cabinet surface, making the suction cup component 3 suitable for cabinet surface conditions with poor flatness, improving the adhesion between the suction cup component 3 and the cabinet surface, and enhancing its applicability and reliability under different cabinet surface environments. The remote control operating mechanism for the ring main unit provided by this utility model can ensure operational accuracy and reliability under complex working conditions.

[0041] Figure 2This is a partial structural diagram of a remote control operating mechanism for a ring main unit provided in this embodiment. In some embodiments, such as... Figure 2 As shown, the adjustment assembly 2 includes a first adjustment mechanism 21 and a second adjustment mechanism 22. The first adjustment mechanism 21 is connected to the support arm 1. The first adjustment mechanism 21 is capable of reciprocating along a first direction on the support arm 1. The second adjustment mechanism 22 is connected to the first adjustment mechanism 21. The second adjustment mechanism 22 is capable of reciprocating along a second direction on the first adjustment mechanism 21. The suction cup assembly 3 is connected to the second adjustment mechanism 22.

[0042] In some examples, such as Figure 1 and Figure 2 As shown, the first direction is the length direction of the support arm 1, and the second direction is perpendicular to the first direction. This configuration allows the suction cup assembly 3 to have the freedom to tilt in both directions, making it suitable for cabinet surfaces with various angles.

[0043] The adjustment component 2 in this embodiment includes a first adjustment mechanism 21 and a second adjustment mechanism 22. The first adjustment mechanism 21 can reciprocate along a first direction on the support arm 1, and the second adjustment mechanism 22 can reciprocate along a second direction on the first adjustment mechanism 21. The suction cup assembly 3 is connected to the second adjustment mechanism 22. By controlling the rotation of the first adjustment mechanism 21, the tilt angle of the suction cup assembly 2 in the first direction can be adjusted. By controlling the rotation of the second adjustment mechanism 22, the tilt angle of the suction cup assembly 3 in the second direction can be adjusted. This improves the freedom of angle adjustment of the suction cup assembly 3, expands its applicability, and helps reduce the difficulty of operating the ring main unit.

[0044] In some embodiments, such as Figure 2 As shown, the first adjustment mechanism 21 includes a connecting seat 211 and a first telescopic rod 212. The connecting seat 211 is hinged to the support arm 1. The first telescopic rod 212 is hinged between the support arm 1 and the connecting seat 211. By controlling the extension and retraction of the first telescopic rod 212, the connecting seat 211 can be driven to reciprocate in a first direction.

[0045] In some examples, such as Figure 2 As shown, the first telescopic rod 212 is an electric telescopic rod. Electric telescopic rods are convenient to control, respond quickly, and help reduce structural weight. However, it is understood that in other embodiments, the first telescopic rod 212 may also be pneumatically or hydraulically driven.

[0046] In some examples, such as Figure 1 and Figure 2 As shown, the first direction is the length direction of the support arm 1. By controlling the extension and retraction of the first telescopic rod 212, the connecting seat 211 is driven to rotate back and forth in the first direction, thereby adjusting the tilt angle of the connecting seat 211 in the first direction.

[0047] The first adjustment mechanism 21 in this embodiment includes a connecting seat 211 and a first telescopic rod 212. By controlling the extension and retraction of the first telescopic rod 212, the tilt angle of the connecting seat 211 in the first direction can be adjusted. The structure is simple, the control is convenient, and the operation is reliable.

[0048] Figure 3 This is a partial structural cross-sectional view of a remote control operating mechanism for a ring main unit provided in this embodiment. Figure 6 for Figure 3 A magnified view of point B. In some embodiments, such as Figure 3 and Figure 6 As shown, the second adjustment mechanism 22 includes a semi-circular support block 221, a worm gear 222, and a drive motor 223. The semi-circular support block 221 is rotatably mounted on the connecting seat 211. A turbine structure 224 is provided on the outer periphery of the semi-circular support block 221. The worm gear 222 is rotatably mounted on the connecting seat 211. The worm gear 222 meshes with the turbine structure 224 for transmission. The drive motor 223 is connected to the worm gear 222. The drive motor 223 drives the semi-circular support block 221 to reciprocate in a second direction through the cooperation of the worm gear 222 and the turbine structure 224. The suction cup assembly 3 is connected to the semi-circular support block 221.

[0049] In some examples, such as Figure 3 As shown, the semi-circular support block 221 is on the connecting seat 211 and can reciprocate along the axial direction of the worm 222. In this embodiment, the axial direction of the worm 222 is the second direction. Furthermore, in this embodiment, the second direction is perpendicular to the first direction.

[0050] In some examples, such as Figure 3 As shown, the turbine structure 224 is disposed on the outer periphery of the semi-circular support block 221 and extends along the circumference of the semi-circular support block 221, so the turbine structure 224 is also semi-circular. The drive motor 223 drives the worm gear 222 to reciprocate, and the worm gear 222 meshes with the turbine structure 224 for transmission, thereby driving the semi-circular support block 221 to reciprocate in the second direction.

[0051] The second adjustment mechanism 22 in this embodiment includes a semi-circular support block 221, a worm gear 222, and a drive motor 223. The drive motor 223 drives the worm gear 222 to reciprocate, and the worm gear 222 meshes with the turbine structure 224 for transmission, thereby driving the semi-circular support block 221 to reciprocate in the second direction. The suction cup assembly 3 is connected to the semi-circular support block 221 and rotates synchronously with the semi-circular support block 221, thereby adjusting the tilt angle of the suction cup assembly 3 in the second direction.

[0052] Figure 5 for Figure 2 A magnified view of point A. In some embodiments, such as Figure 2 andFigure 5 As shown, the first adjusting mechanism 21 further includes a first connecting block 213 and a second connecting block 214. The first connecting block 213 is disposed on the support arm 1. The connecting seat 211 is provided with a first sliding groove 215. The second connecting block 214 is slidably disposed in the first sliding groove 215. The first telescopic rod 212 is hinged between the first connecting block 213 and the second connecting block 214.

[0053] In some examples, such as Figure 2 and Figure 5 As shown, the first slide groove 215 is arranged in the vertical direction. The first slide groove 215 adopts a trapezoidal groove, which can both limit the second connecting block 214 to prevent the second connecting block 214 from coming out of the first slide groove, and allow the second connecting block 214 to slide in the vertical direction.

[0054] The first adjustment mechanism 21 in this embodiment further includes a first connecting block 213 and a second connecting block 214. The first connecting block 213 is disposed on the support arm 1, and the second connecting block 214 is slidably disposed in the first groove 215 on the connecting seat 211. As the first telescopic rod 212 extends and retracts, the second connecting block 214 can slide in the first groove 215 to adapt to changes in the tilt angle of the connecting seat 211, thus avoiding interference between the first telescopic rod 212 and the connecting seat 211 when adjusting the angle of the connecting seat 211.

[0055] Figure 4 This is a partial cross-sectional view of a circular support block provided in this embodiment. In some embodiments, such as... Figure 4 As shown, the bottom of the connecting seat 211 is provided with an arc-shaped surface 216. The curvature of the arc-shaped surface 216 is adapted to the outer circumference curvature of the semi-circular support block 221. A guide slider 217 is provided on the arc-shaped surface 216. A second sliding groove 225 is provided on the semi-circular support block 221. The semi-circular support block 221 is rotatably connected to the arc-shaped surface 216 through the cooperation of the second sliding groove 225 and the guide slider 217.

[0056] In some examples, such as Figure 4 As shown, the second groove 225 is arranged circumferentially along the semicircular support block 221, and is therefore also semicircular. The guide slider 217 includes a guide rod and a limiting block connected to each other. The free end of the guide rod passes through the second groove 225 and connects to the arc surface 216. The width of the limiting block is greater than the width of the second groove 225, so as to support and limit the semicircular support block 221, allowing the semicircular support block 221 to be slidably connected to the arc surface 216. The drive motor 223 drives the worm gear 222 to reciprocate, and the worm gear 222 meshes with the turbine structure 224 for transmission, thereby driving the semicircular support block 221 to reciprocate on the arc surface 216, thereby adjusting the tilt angle of the suction cup assembly 3 in the second direction.

[0057] In some examples, such as Figure 4 As shown, the bottom of the connecting seat 211 has arc-shaped surfaces 216 on both sides. The semi-circular support block 221 also has second sliding grooves 225 on both sides. Each arc-shaped surface 216 has a guide slider 217, and each second sliding groove 225 cooperates with a guide slider 217. This arrangement makes the connection between the semi-circular support block 221 and the connecting seat 211 more stable and reliable, and ensures that the semi-circular support block 221 is subjected to balanced forces and rotates smoothly.

[0058] In this embodiment, the connecting seat 211 and the semi-circular support block 221 are adapted to each other through the arc surface 216, and are connected through the cooperation of the second slide groove 225 and the guide slider 217, so that the semi-circular support block 221 can rotate on the arc surface 216 along the second direction, thereby adjusting the tilt angle of the suction cup assembly 3 in the second direction.

[0059] In some embodiments, such as Figure 3 and Figure 4 As shown, the connecting seat 211 has an internal receiving cavity. The receiving cavity includes a first support plate 218 and a second support plate 219. The worm gear 222 is rotatably disposed between the first support plate 218 and the second support plate 219. A semi-circular support block 221 is located below the worm gear 222. The outer peripheral surface of the semi-circular support block 221 faces the worm gear 222.

[0060] In some examples, such as Figure 3 and Figure 4 As shown, the first support plate 218 and the second support plate 219 are respectively connected to the front and rear ends of the connecting seat 211. The worm gear 222 is rotatably disposed between the first support plate 218 and the second support plate 219. The drive motor 223 is disposed on the first support plate 218 / second support plate 219 and connected to the worm gear 222. The support is stable and the structure is reasonable.

[0061] In this embodiment, the worm gear 222 is installed in the receiving cavity inside the connecting seat 211 by the cooperation of the first support plate 218 and the second support plate 219, making the structure of the adjustment component 2 more compact and reasonable.

[0062] In some embodiments, such as Figure 2 and Figure 3 As shown, the suction cup assembly 3 includes a mounting plate 31, a suction cup 32, and a vacuum pump 33. The mounting plate 31 is connected to the adjusting assembly 2. The suction cup 32 is connected to the side of the mounting plate 31 away from the adjusting assembly 2. The vacuum pump 33 is mounted on the mounting plate 31. The vacuum pump 33 is connected to the suction cup 32 via a connecting pipe 34 to extract air between the suction cup 32 and the cabinet surface. The clamping assembly 4 is vertically and vertically mounted on the mounting plate 31. The clamping assembly 4 can press down on the suction cup 32 to expel air between the suction cup 32 and the cabinet surface.

[0063] In some examples, such as Figure 3 and Figure 4 As shown, the mounting plate 31 is connected to the semi-circular support plate 221. The outer circumferential surface of the semi-circular support plate 221 faces the worm gear 222, and the inner circumferential surface of the semi-circular support plate 221 faces the mounting plate 31. This arrangement connects the mounting plate 31 with the planes on both sides of the semi-circular support plate 221, making the connection between the mounting plate and the semi-circular support plate more secure and reliable.

[0064] Mounting plate 31 is connected to semi-circular support plate 221 with the inner circumferential surface of semi-circular support plate 221 facing mounting plate 31. Therefore, a receiving space is formed between the top of mounting plate 31 and the inner circumferential surface of semi-circular support plate 221. Vacuum pump 33 is installed in this receiving space and is connected to suction cup 32 through connecting pipe 34.

[0065] In some examples, such as Figure 2 and Figure 3 As shown, the suction cup 32 is connected to the side of the mounting plate 31 away from the adjustment component 2 via a lifting rod 35. The lifting rod 35 can drive the suction cup 32 down to approach the cabinet surface of the ring main unit, thereby allowing the suction cup 32 to adhere to the cabinet surface.

[0066] The suction cup assembly 3 in this embodiment includes a mounting plate 31, a suction cup 32, and a vacuum pump 33. The mounting plate 31 is connected to the adjustment assembly 2. The adjustment assembly 2 rotates the mounting plate 31 to adjust the tilt angle of the suction cup 32 to accommodate cabinet surfaces at different angles. The vacuum pump 33 is connected to the suction cup 32 via a connecting pipe 34 to extract the air between the suction cup 32 and the cabinet surface, ensuring a tight seal between the suction cup 32 and the cabinet surface.

[0067] In this embodiment, the adjustment component 2, when in use, controls the extension and retraction of the first telescopic rod 212, thereby causing the suction cup 32 to undergo an initial angular change in one direction. Then, the drive motor 223 is controlled to rotate the worm gear 222, and the semi-circular support block 221 rotates under the transmission of the worm gear 222 and the worm wheel structure 224, thereby causing the mounting plate 31 and the suction cup 32 to rotate in a second direction, performing a second angular adjustment of the suction cup 32. The angle of the suction cup 32 can be flexibly fine-tuned according to actual needs, ensuring that the suction cup 32 fits the cabinet surface at the optimal angle for processing, greatly improving the adaptability of the suction cup 32 to the target surface, effectively enhancing the adsorption effect, and improving the operational accuracy and reliability of the entire operating mechanism under complex working conditions.

[0068] In some embodiments, such as Figure 2 and Figure 3As shown, the pressing assembly 4 includes: a first ring 41, a second ring 42, a plurality of second telescopic rods 43, and a plurality of pressure rod mechanisms 44. The first ring 41 is connected to the suction cup assembly 3. The second ring 42 is connected to the first ring 41 via the plurality of second telescopic rods 43. The plurality of pressure rod mechanisms 44 are located on the side of the second ring 42 away from the second telescopic rods 43. By controlling the extension and retraction of the plurality of second telescopic rods 43, the second ring 42 can be moved away from or closer to the first ring 41. When the second ring 42 moves away from the first ring 41, the pressure rod mechanism 44 can press the suction cup assembly 3 onto the cabinet surface to expel the air between the suction cup assembly 3 and the cabinet surface.

[0069] In some examples, such as Figure 2 and Figure 3 As shown, the multiple second telescopic rods 43 are electrically operated. Electrically operated telescopic rods offer convenient control, rapid response, and help reduce structural weight. However, it is understood that in other embodiments, the second telescopic rods 43 may also be pneumatically or hydraulically driven.

[0070] In some examples, such as Figure 3 As shown, the first ring 41 is connected to the mounting plate 31 by multiple connecting rods 45. The connecting rods 45 are L-shaped, with one end connected to the top surface of the mounting plate 31 and the other end connected to the inner wall of the first ring 41. This arrangement effectively fixes the first ring 41 to the mounting plate 31 without occupying the bottom space of the first ring 41, facilitating the installation of the second ring 42 and multiple second telescopic rods 43.

[0071] The pressing assembly 4 in this embodiment includes a first ring 41, a second ring 42, a plurality of second telescopic rods 43, and a plurality of pressure rod mechanisms 44. By controlling the extension of the plurality of second telescopic rods 43, the second ring 42 can be moved toward the cabinet surface, thereby driving the pressure rod mechanisms 44 to move toward the suction cup 42 until the suction cup 42 is pressed onto the cabinet surface to expel the air between the suction cup 42 and the cabinet surface. Therefore, even if the flatness of the cabinet surface is poor, the suction cup 42 can be tightly adhered to the cabinet surface.

[0072] In some embodiments, such as Figure 2 and Figure 3 As shown, the pressure rod mechanism 44 includes: a third telescopic rod 441, a pressure plate 442, and a spring 443. One end of the third telescopic rod 441 is connected to the second ring 42. The pressure plate 442 is disposed at the end of the third telescopic rod 441 away from the second ring 42. The spring 443 is sleeved on the third telescopic rod 441. The spring 443 is supported between the second ring 42 and the pressure plate 442.

[0073] In some examples, such as Figure 2 and Figure 3 As shown, tablet 442 is circular.

[0074] The pressure rod mechanism 44 in this embodiment includes a third telescopic rod 441, a pressure plate 442, and a spring 443. When it is necessary to eliminate air bubbles between the suction cup 32 and the cabinet surface, multiple second telescopic rods 43 are controlled to extend synchronously, driving the second ring 42 to move downward. At this time, the pressure plate 442 on the third telescopic rod 441 will press the suction cup 32 firmly.

[0075] If the dimensions of the uneven surface on the cabinet surface within the coverage area of ​​the suction cup 32 are inconsistent, the spring 443 can be compressed as the second ring 42 moves downward, allowing the multiple pressure rod structures 44 to adapt to these cabinet surfaces of different heights. This effectively solves the problem of loose adhesion caused by air bubbles, enhances the adhesion force between the suction cup and the cabinet surface, and ensures the firmness of the adhesion. In this embodiment, the pressure rod mechanism 44, facing uneven cabinet surfaces, allows the spring 443 to flexibly adapt to these irregularities, enabling the pressure plate 442 to apply pressure evenly to the suction cup 32. This ensures that the suction cup 32 can adhere tightly under various complex cabinet surface conditions, significantly improving the applicability and reliability of the operating mechanism in different cabinet surface environments.

[0076] The structure of the remote control operating mechanism for the ring main unit in this embodiment has been described above. Next, the method of using the remote control operating mechanism for the ring main unit in this embodiment will be introduced:

[0077] In use, hold the handle 12 on the support arm 1, place the suction cup 32 on the cabinet surface to be treated, and then press a control button 11 to activate the first telescopic rod 212. Under the combined action of the first connecting block 213, the first sliding groove 215, and the second connecting block 214, the first telescopic rod 212 will cause the suction cup 32 to undergo its first angle change. Then, press another control button 11 as needed to activate the drive motor 223. The drive motor 223 drives the worm gear 222 to rotate. Under the transmission action of the worm gear 222 and the turbine structure 224, the semi-circular support block 221 will drive the mounting plate 31 and the suction cup 32 to rotate, performing a second angle adjustment of the suction cup 32. After the angle adjustment is completed, the suction cup 32 can be aligned with the position to be treated. Then, the vacuum pump 33 can be activated by another control button 22. The vacuum pump 33 will draw a vacuum between the suction cup 32 and the cabinet surface to be treated through the connecting pipe 34, achieving adsorption of the cabinet surface. If the cabinet surface is not flat, air bubbles will still exist between the suction cup 32 and the cabinet surface under the action of the vacuum pump 33, resulting in a loose adhesion between the suction cup 32 and the cabinet surface. Multiple second telescopic rods 43 can be controlled by the control button 11 to move the second ring 42 downward. At this time, the pressure plate 442 on the third telescopic rod 441 will press the suction cup 32 firmly. If there are uneven surfaces on the cabinet surface, the elasticity of the spring 443 can also compress the third telescopic rod 441 to adapt to these uneven surfaces.

[0078] The remote control operating mechanism for the ring main unit in this embodiment solves the problem that existing vacuum suction cup operating mechanisms are not easy to stably adsorb onto uneven cabinet surfaces during use. Because the suction force of a vacuum suction cup depends on its sealing performance, if the contact surface is uneven or has tiny gaps, vacuum negative pressure alone is insufficient to completely eliminate these gaps, resulting in insufficient suction force. However, the remote control operating mechanism for the ring main unit in this embodiment, through the cooperation of the support arm, adjusting components, suction cup components, and clamping components, can be applied to cabinet surfaces of different angles and with poor flatness.

[0079] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

The above are only preferred embodiments of this utility model.
