Description

Technical Field

[0001] The present invention belongs to the technical field of ring main units, and particularly relates to a remote control operating mechanism for a ring main unit. Background Art

[0002] A ring main unit is a combination of high-voltage switchgear used in a power system, usually composed of components such as a load switch, a fuse, a disconnector, an earthing switch, a busbar, and a cable terminal. These components are installed in an enclosed metal cabinet or a fabricated sectional structure to form a complete power supply unit. The ring main unit is mainly applied to the medium-voltage power distribution network to receive and distribute electric energy, and to control, protect, and monitor the circuit. When a circuit breaker fails, manual close-range operation poses a great safety hazard and may cause serious threats to the personal safety of the operator. Therefore, tools are needed to perform remote operation on it. During the use of existing suction cup tools, since the adsorption force of the suction cup depends on the sealing performance, if the cabinet surface of the ring main unit is uneven or there are small gaps, it is not easy to completely eliminate the gaps only by vacuum negative pressure, resulting in insufficient adsorption force and inability to stably adsorb the uneven cabinet surface.

[0038] In some examples, as Figure 1 shown, a handle 12 is provided on the support arm 1, and the handle 12 is close to the end of the support arm 1 away from the adjustment component 2. With such a setting, it is convenient for the operator to hold, which is beneficial to improving the operation accuracy and stability. In this embodiment, there are two handles 12 on the support arm 1 and they are located in different directions respectively.

However, it should be noted that in other embodiments, the adjustment component 2, the suction cup component 3, and the pressing component 4 can also be wirelessly controlled, and the control end can be located on the support arm 1 or can be designed separately from the support arm 1.

[0040] The remote control operating mechanism 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 direction and the second direction, so that the suction cup component 3 can fit the cabinet surface at the best angle, improving the adaptability between the suction cup component 3 and the cabinet surface, which is beneficial to enhancing the adsorption effect. The pressing component 4 can press down the suction cup component 3 to discharge the air between the suction cup component 3 and the cabinet surface, so that the suction cup component 3 can be applicable to the cabinet surface conditions with poor flatness, improving the fit degree between the suction cup component 3 and the cabinet surface, and improving the applicability and reliability in different cabinet surface environments. The remote control operating mechanism provided by the present invention can ensure the operation accuracy and reliability under complex working conditions.

[0041] Figure 2The figure is a schematic diagram of a partial structure of a remote control operating mechanism for a ring main unit provided in this embodiment. In some embodiments, such as Figure 2 shown, the adjusting assembly 2 includes: a first adjusting mechanism 21 and a second adjusting mechanism 22. The first adjusting mechanism 21 is connected to the support arm 1. The first adjusting mechanism 21 can reciprocally rotate on the support arm 1 along a first direction. The second adjusting mechanism 22 is connected to the first adjusting mechanism 21. The second adjusting mechanism 22 can reciprocally rotate on the first adjusting mechanism 21 along a second direction. The suction cup assembly 3 is connected to the second adjusting mechanism 22.

[0042] In some examples, such as Figure 1 and Figure 2 shown, the first direction is the length direction of the support arm 1, and the second direction is perpendicular to the first direction. With such a setting, the suction cup assembly 3 can have the freedom of inclination in two directions, and can be applicable to cabinet surfaces at various different angles.

[0043] The adjusting assembly 2 of this embodiment includes a first adjusting mechanism 21 and a second adjusting mechanism 22. The first adjusting mechanism 21 can reciprocally rotate on the support arm 1 along a first direction, the second adjusting mechanism 22 can reciprocally rotate on the first adjusting mechanism 21 along a second direction, and the suction cup assembly 3 is connected to the second adjusting mechanism 22. By controlling the rotation of the first adjusting mechanism 21, the inclination angle of the suction cup assembly 2 in the first direction can be adjusted, and by controlling the rotation of the second adjusting mechanism 22, the inclination angle of the suction cup assembly 3 in the second direction can be adjusted, which improves the freedom of angle adjustment of the suction cup assembly 3, increases the applicable range, and is beneficial to reducing the operation difficulty of the ring main unit.

[0044] In some embodiments, such as Figure 2 shown, the first adjusting 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 reciprocally rotate in the first direction.

[0045] In some examples, such as Figure 2 shown, the first telescopic rod 212 is an electric telescopic rod. Using an electric telescopic rod is convenient for control, has a rapid response, and is beneficial to reducing the structural weight. However, it can be understood that in other embodiments, the first telescopic rod 212 can also be driven pneumatically or hydraulically.

[0046] In some examples, such as Figure 1 and Figure 2 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 reciprocally rotate in the first direction, and thus the inclination angle of the connecting seat 211 in the first direction is adjusted.

[0047] The first adjustment mechanism 21 of this embodiment includes a connecting seat 211 and a first telescopic rod 212. By controlling the telescopic movement of the first telescopic rod 212, the inclination 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 It is a partial structural sectional view of a remote control operating mechanism of a ring main unit provided in this embodiment. Figure 6 It is Figure 3 The enlarged view of part B of. In some embodiments, such as Figure 3 and Figure 6 shown, the second adjustment mechanism 22 includes: a semi-circular support block 221, a worm 222, and a driving motor 223. The semi-circular support block 221 is rotatably arranged on the connecting seat 211. A turbine structure 224 is provided on the outer periphery of the semi-circular support block 221. The worm 222 is rotatably arranged on the connecting seat 211. The worm 222 is in meshing transmission with the turbine structure 224. The driving motor 223 is connected to the worm 222. The driving motor 223 drives the semi-circular support block 221 to rotate reciprocally in the second direction through the cooperation of the worm 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 shown, the semi-circular support block 221 is on the connecting seat 211 and can rotate reciprocally in the axial direction of the worm 222. In this embodiment, the axial direction of the worm 222 is the second direction. And the second direction in this embodiment is perpendicular to the first direction.

[0050] In some examples, such as Figure 3 shown, the turbine structure 224 is arranged on the outer periphery of the semi-circular support block 221 and extends along the circumferential direction of the semi-circular support block 221. Therefore, the turbine structure 224 is also semi-circular. The driving motor 223 drives the worm 222 to rotate reciprocally, and the worm 222 is in meshing transmission with the turbine structure 224, thereby driving the semi-circular support block 221 to rotate reciprocally in the second direction.

[0051] The second adjustment mechanism 22 of this embodiment includes a semi-circular support block 221, a worm 222, and a driving motor 223. The driving motor 223 drives the worm 222 to rotate reciprocally, and the worm 222 is in meshing transmission with the turbine structure 224, thereby driving the semi-circular support block 221 to rotate reciprocally 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 inclination angle of the suction cup assembly 3 in the second direction.

[0052] Figure 5 It is Figure 2 The enlarged view of part A of. 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 arranged on the support arm 1. A first sliding groove 215 is provided on the connecting seat 211. The second connecting block 214 is slidably arranged 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 sliding groove 215 is arranged in the vertical direction. The first sliding groove 215 adopts a trapezoidal groove, which can not only limit the second connecting block 214 to prevent it from slipping out of the first sliding groove, but also enable the second connecting block 214 to slide in the vertical direction.

[0054] The first adjusting mechanism 21 of this embodiment further includes a first connecting block 213 and a second connecting block 214. The first connecting block 213 is arranged on the support arm 1, and the second connecting block 214 is slidably arranged in the first sliding groove 215 on the connecting seat 211. As the first telescopic rod 212 expands and contracts, the second connecting block 214 can slide in the first sliding groove 215 to adapt to the change in the inclination angle of the connecting seat 211, and avoid 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 schematic diagram of a circular support block provided by this embodiment. In some embodiments, such as Figure 4 as shown, an arc surface 216 is provided at the bottom of the connecting seat 211. The radian of the arc surface 216 is adapted to the outer peripheral radian of the semi-circular support block 221. A guiding slider 217 is provided on the arc 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 surface 216 through the cooperation of the second sliding groove 225 and the guiding slider 217.

[0056] In some examples, such as Figure 4 as shown, the second sliding groove 225 is arranged along the circumferential direction of the semi-circular support block 221, so it is also semi-circular. The guiding slider 217 includes a guiding rod and a limiting block connected to each other. The free end of the guiding rod passes through the second sliding groove 225 and is connected to the arc surface 216. The width of the limiting block is greater than the width of the second sliding groove 225 to support and limit the semi-circular support block 221, so that the semi-circular support block 221 is slidably connected to the arc surface 216. The driving motor 223 drives the worm 222 to rotate reciprocally, and the worm 222 meshes with the turbine structure 224 for transmission, thereby driving the semi-circular support block 221 to rotate reciprocally on the arc surface 216, and further adjusting the inclination angle of the suction cup assembly 3 in the second direction.

[0057] In some examples, such as Figure 4 shown, arc surfaces 216 are respectively provided on both sides of the bottom of the connecting seat 211. Second sliding grooves 225 are also respectively provided on both sides of the semi-circular support block 221. A guiding slider 217 is provided on each arc surface 216, and each second sliding groove 225 is matched with a guiding slider 217. With such a setting, the connection between the semi-circular support block 221 and the connecting seat 211 can be made more stable and reliable, and the semi-circular support block 221 can be balanced in force and rotate 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 the connection is realized through the cooperation of the second sliding groove 225 and the guiding slider 217, so that the semi-circular support block 221 can rotate along the second direction on the arc surface 216, thereby adjusting the inclination angle of the suction cup assembly 3 in the second direction.

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

[0060] In some examples, such as Figure 3 and Figure 4 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 222 is rotatably arranged between the first support plate 218 and the second support plate 219, the driving motor 223 is arranged on the first support plate 218 / the second support plate 219, and is connected to the worm 222. The support is stable and the structure is reasonable.

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

[0062] In some embodiments, such as Figure 2 and Figure 3 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 arranged on the mounting plate 31. The vacuum pump 33 is connected to the suction cup 32 through a connecting pipe 34 for pumping out the air between the suction cup 32 and the cabinet surface. The pressing assembly 4 is arranged on the mounting plate 31 in a liftable manner. The pressing assembly 4 can press down the suction cup 32 to discharge the 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 peripheral surface of the semi-circular support plate 221 faces the worm 222, and the inner peripheral surface of the semi-circular support plate 221 faces the mounting plate 31. With such a setting, the mounting plate 31 is connected to the flat surfaces on both sides of the semi-circular support plate 221, which can make the connection between the mounting plate and the semi-circular support plate more firm and reliable.

[0064] The mounting plate 31 is connected to the semi-circular support plate 221 and the inner peripheral surface of the semi-circular support plate 221 faces the mounting plate 31. Therefore, a receiving space is formed between the top of the mounting plate 31 and the inner peripheral surface of the semi-circular support plate 221. The vacuum pump 33 is installed in this receiving space and is connected to the suction cup 32 through the 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 adjusting component 2 through the lifting rod 35. The lifting rod 35 can drive the suction cup 32 to descend to approach the cabinet surface of the ring main unit, so that the suction cup 32 can adsorb on the cabinet surface.

[0066] The suction cup assembly 3 of this embodiment includes a mounting plate 31, a suction cup 32 and a vacuum pump 33. The mounting plate 31 is connected to the adjusting component 2. The adjusting component 2 drives the mounting plate 31 to rotate, thereby adjusting the inclination angle of the suction cup 32 to adapt to cabinet surfaces at different angles. The vacuum pump 33 is connected to the suction cup 32 through the connecting pipe 34 to extract the air between the suction cup 32 and the cabinet surface, so that the suction cup 32 is tightly sucked to the cabinet surface.

[0067] When the adjusting component 2 of this embodiment is in use, by controlling the expansion and contraction of the first telescopic rod 212, the suction cup 32 is driven to have a first angle change in one direction; then, by controlling the driving motor 223 to drive the worm 222 to rotate, the semi-circular support block 221 rotates under the action of the transmission between the worm 222 and the worm gear structure 224, thereby driving the mounting plate 31 and the suction cup 32 to rotate in the second direction, and performing a second angle adjustment on the suction cup 32. The angle of the suction cup 32 can be flexibly fine-tuned according to actual needs to ensure that the suction cup 32 can fit the cabinet surface of the position to be processed at the best angle, greatly improving the adaptability of the suction cup 32 to the target surface, effectively enhancing the adsorption effect, and improving the operation accuracy and reliability of the entire operating mechanism under complex working conditions.

[0068] In some embodiments, such as Figure 2 and Figure 3As shown in the figure, the pressing assembly 4 includes: a first ring 41, a second ring 42, a plurality of second telescopic rods 43, and a plurality of pressing 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 through a plurality of second telescopic rods 43. A plurality of pressing rod mechanisms 44 are arranged on the side of the second ring 42 away from the second telescopic rods 43. By controlling the expansion and contraction of the plurality of second telescopic rods 43, the second ring 42 can be moved away from or close to the first ring 41. When the second ring 42 moves away from the first ring 41, the pressing rod mechanism 44 can press the suction cup assembly 3 against the countertop to discharge the air between the suction cup assembly 3 and the countertop.

[0069] In some examples, as Figure 2 and Figure 3 shown, the plurality of second telescopic rods 43 are electric telescopic rods. Using electric telescopic rods is convenient to control, has a rapid response, and is beneficial to reducing the structural weight. However, it can be understood that in other embodiments, the second telescopic rod 43 can also be driven pneumatically or hydraulically.

[0070] In some examples, as Figure 3 shown, the first ring 41 is connected to the mounting plate 31 through a plurality of 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. With such a setting, the first ring 41 can be effectively fixed on the mounting plate 31, and the bottom space of the first ring 41 is not occupied, which is convenient for the arrangement of the second ring 42 and the plurality of second telescopic rods 43.

[0071] The pressing assembly 4 of this embodiment includes a first ring 41, a second ring 42, a plurality of second telescopic rods 43, and a plurality of pressing rod mechanisms 44. By controlling the elongation of the plurality of second telescopic rods 43, the second ring 42 can be moved towards the countertop, thereby driving the pressing rod mechanism 44 to move towards the suction cup 42 until the suction cup 42 is pressed against the countertop to discharge the air between the suction cup 42 and the countertop. Therefore, even if the flatness of the countertop is poor, the suction cup 42 can be tightly suctioned to the countertop.

[0072] In some embodiments, as Figure 2 and Figure 3 shown, the pressing rod mechanism 44 includes: a third telescopic rod 441, a pressing piece 442, and a spring 443. One end of the third telescopic rod 441 is connected to the second ring 42. The pressing piece 442 is arranged 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 pressing piece 442.

[0073] In some examples, as Figure 2 and Figure 3 shown, the pressing piece 442 is circular.

[0074] The pressing rod mechanism 44 of this embodiment includes a third telescopic rod 441, a pressing piece 442, and a spring 443. When it is necessary to eliminate the air bubbles between the suction cup 32 and the cabinet surface, control the plurality of second telescopic rods 43 to extend synchronously, driving the second ring 42 to move downward. At this time, the pressing piece 442 on the third telescopic rod 441 will compact the suction cup 32.

[0075] If the sizes of the unevenness on the cabinet surface within the coverage of the suction cup 32 are inconsistent, as the second ring 42 moves downward, the spring 443 can be compressed so that the plurality of pressing rod structures 44 can adapt to these cabinet surfaces of different heights, thereby effectively solving the problem of insufficient adsorption caused by the existence of air bubbles, enhancing the adsorption force between the suction cup and the cabinet surface, and ensuring the firmness of adsorption. Facing the uneven cabinet surface, the elasticity of the spring 443 of the pressing rod mechanism 44 of this embodiment can flexibly adapt to these irregular conditions, enabling the pressing piece 442 to uniformly apply pressure to the suction cup 32, ensuring that the suction cup 32 can be closely attached under various complex cabinet surface conditions, and significantly improving the applicability and reliability of the operating mechanism in different cabinet surface environments.

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

[0077] When in use, hold the handle 12 on the support arm 1, place the suction cup 32 at the position of the cabinet surface to be processed, and then press a certain control button 11 to start the first telescopic rod 212. Under the combined action of the first connecting block 213, the first chute 215, and the second connecting block 214, the first telescopic rod 212 will drive the suction cup 32 to undergo the first angle change; then, press another control button 11 according to the need to start the drive motor 223. The drive motor 223 drives the worm 222 to rotate. Under the transmission of the worm 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 the second angle adjustment on the suction cup 32. After the angle adjustment is completed, the suction cup 32 can be aligned with the position to be processed, and then start the vacuum pump 33 through another control button 22. The vacuum pump 33 evacuates the space between the suction cup 32 and the cabinet surface to be processed through the connecting pipe 34 to achieve the adsorption of the cabinet surface. If the flatness of the cabinet surface is poor, under the action of the vacuum pump 33, there are still air bubbles between the suction cup 32 and the cabinet surface, resulting in insufficient adsorption between the suction cup 32 and the cabinet surface. The plurality of second telescopic rods 43 can be controlled through the control button 11 to drive the second ring 42 to move downward. At this time, the pressing piece 442 on the third telescopic rod 441 will compact the suction cup 32. If there are uneven surfaces such as bumps and depressions 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 of the ring main unit in this embodiment solves the problem that the existing vacuum suction cup operating mechanism is not convenient for stably adsorbing the uneven cabinet surface during use. Since the adsorption force of the vacuum suction cup depends on the sealing performance, if the contact surface is uneven or there are small gaps, it is not convenient to completely eliminate the gaps only by the vacuum negative pressure, resulting in insufficient adsorption force. However, the remote control operating mechanism of the ring main unit in this embodiment can be applied to cabinet surfaces with different angles and poor flatness through the cooperation of the support arm, the adjustment component, the suction cup component and the pressing component.

[0079] It is easy for those skilled in the art to understand that, on the premise of no conflict, the above advantageous ways can be freely combined and superimposed.

[0080] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. The above is only the preferred implementation manner of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
