Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to an electric mechanism with grounded electric operation. Background Technology

[0002] In the operation and maintenance of power systems, grounding is a crucial link in ensuring the safety of equipment and personnel. Traditional manual grounding operations not only require operators to expend a great deal of physical effort, but also present numerous inconveniences when dealing with equipment in compact layouts and complex operating environments. Furthermore, limited operating space may prevent accurate and timely completion of grounding tasks, posing potential risks to the safe and stable operation of the power system. With the continuous development of the power industry, the demand for electric operating mechanisms is increasing. While existing electric operating mechanisms have achieved automation to some extent and reduced the labor intensity of operators, there are still some unresolved issues in structural design and functional implementation. Many electric operating mechanisms have dispersed component layouts, resulting in an insufficiently compact overall structure and a large space occupation. The transmission component design of some electric operating mechanisms is inadequate, leading to significant energy loss and low transmission efficiency during transmission. Moreover, electric operating mechanisms often lack precision and safety in operation. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide an electric mechanism with reliable grounding protection, intelligent electric operation control and adaptability to the application needs of multiple scenarios, which has grounding electric operation.

[0004] To achieve the above objectives, this utility model employs an electric mechanism with grounding electric operation, including a grounding bracket. A base plate is fixedly installed at one end of the grounding bracket, and a grounding motor mounting plate is fixedly installed at the other end. A grounding transmission assembly is arranged in the internal space enclosed by the base plate and the grounding bracket. A grounding motor is connected to the grounding motor mounting plate. A grounding blade spindle is coaxially arranged on the base plate, the grounding bracket, the grounding motor mounting plate, and the grounding motor. The grounding blade spindle passes through the base plate, the grounding bracket, and the grounding motor mounting plate and extends into the interior of the grounding motor. One end of the spindle abuts against the rotor of the grounding motor, and the other end is installed in the base plate through a grounding blade bushing. A grounding operation cam is sleeved on the grounding blade spindle between the grounding motor and the grounding motor mounting plate.

[0005] The beneficial effects of the above structure are as follows: by orderly combining components such as the grounding bracket, base plate, and grounding motor mounting plate, a compact overall structure is constructed. The grounding knife spindle coaxially runs through multiple key components, which not only reduces unnecessary space occupation but also makes the relative positional relationship between the components more precise and stable, effectively improving the structural compactness of the entire electric mechanism. This facilitates installation and use in limited spaces. Furthermore, one end of the grounding knife spindle abuts against the rotor of the grounding motor, while the other end is mounted in the base plate through the grounding knife shaft sleeve. This fixed installation method at both ends provides reliable support for the grounding knife spindle, enabling it to maintain a stable rotational state during operation and preventing swaying or deviation. Its electric operation mode greatly reduces the labor intensity of operators compared to traditional manual operation.

[0006] This utility model is further configured such that a first lower door pull rod pad and a second lower door pull rod pad are respectively provided on the grounding motor mounting plate. A grounding cam support plate is fixedly provided on the first lower door pull rod pad and the second lower door pull rod pad. An opening is provided on the grounding motor mounting plate corresponding to the position of the grounding cam support plate. Both ends of the grounding cam support plate are protruding ends that extend outward through the openings. A first lower door pull rod is inserted into the protruding end. The end of the grounding operation cam abuts against the first lower door pull rod. By setting a first lower door pull rod pad and a second lower door pull rod pad on the grounding motor mounting plate, and fixing the grounding cam support plate on this basis, a stable and reasonable mechanical support system is constructed. An opening is made at the corresponding position of the grounding motor mounting plate, allowing the extended end of the grounding cam support plate to extend outward and connect to the first lower door pull rod. This makes the entire structure more compact and reasonable in terms of spatial layout, making full use of the installation space. At the same time, the end of the grounding operation cam abuts against the first lower door pull rod, forming a clear and definite force transmission path. When the grounding motor drives the grounding operation cam to rotate, the force can be directly and effectively transmitted to the first lower door pull rod, reducing energy loss in the transmission process, improving the accuracy and reliability of the electric mechanism operation, and ensuring that the grounding operation can be executed accurately.

[0007] This utility model is further configured such that a pad support column is also provided on the grounding motor mounting plate. The grounding motor mounting plate is connected to an upper pull rod support plate via the pad support column. A micro switch mounting plate is provided on the upper pull rod support plate, and a micro switch is provided on the micro switch mounting plate. This structure constructs a layered and stable mechanical support structure. The pad support column, as a basic connecting component, provides reliable support for the upper pull rod support plate, ensuring that the upper pull rod support plate remains stable in the horizontal direction and will not shift due to external forces or vibrations during the operation of the electric mechanism. The upper pull rod support plate, in turn, provides a stable mounting platform for the micro switch mounting plate, allowing the micro switch to be fixed in a predetermined position. The layers cooperate with each other, jointly ensuring the stability and reliability of the entire structure under complex working conditions.

[0008] This utility model is further configured such that a sliding plate support block is fixedly installed at one end of the first lower door pull rod near the upper pull rod support plate, and a second lower door pull rod is installed on the sliding plate support block. An interlocking baffle is installed on the second lower door pull rod, and a lower door extension rod is provided at the end of the second lower door pull rod. The sliding plate support block serves as a connecting hub, positioning the installation position of the second lower door pull rod, enabling it to operate stably along its trajectory while avoiding interference with other components. The interlocking baffle on the second lower door pull rod forms an effective interlocking mechanism; when the second lower door pull rod moves, the interlocking baffle moves synchronously, blocking and isolating the operating hole, ensuring that the operation sequence and safety of the entire system meet design requirements. The lower door extension rod further expands the range of action of the second lower door pull rod, allowing it to adapt to the needs of equipment of different sizes and layouts, improving the versatility and flexibility of the electric mechanism.

[0009] This utility model is further configured as a grounding transmission assembly including a grounding transmission plate and a grounding knife bracket built into the grounding transmission plate. The grounding transmission plate is fitted with a grounding pin and a grounding short shaft. The grounding knife bracket is connected to the grounding transmission plate through the grounding short shaft. A spring guide plate is provided inside the grounding knife bracket. One end of the spring guide plate is connected to the grounding short shaft, and the other end is fitted with a base plate shaft. The two ends of the base plate shaft are respectively connected to the base plate and the grounding bracket. A grounding spring is wound on the spring guide plate. One end of the grounding pin is an abutting end that abuts against the grounding bracket, and the other end is an extension end that extends to the outside of the base plate through a grounding groove opened on the base plate. A grounding roller sleeve is fitted on the extension end. The grounding transmission plate integrates a grounding knife bracket to form the core transmission structure. As a basic load-bearing component, the grounding transmission plate provides a stable and reliable clamping platform for the grounding pin and grounding short shaft, ensuring that each component is accurately positioned and firmly connected during transmission. The grounding knife bracket is connected to the grounding bracket via the grounding short shaft, constructing a clear mechanical transmission path. This allows the power during grounding operations to be efficiently and accurately transmitted from the grounding transmission plate to the grounding bracket, reducing energy loss and transmission errors. The spring guide plate connects the grounding short shaft and the base plate shaft. During grounding, the spring guide plate can deform with the movement of the grounding short shaft, and the grounding spring wound on it can store and release energy, playing a role in buffering and resetting.

[0010] This utility model is further configured with a grounding limiting plate inside the base plate and grounding bracket. The grounding limiting plate is mounted on the base plate, and a base plate positioning shaft is also snapped onto the base plate. The grounding limiting plate provides a movement boundary for the components, preventing excessive displacement, while the base plate positioning shaft enhances the positioning function, improving the service life and performance reliability of the equipment.

[0017] like Figures 1-6 As shown, an embodiment of this utility model provides an electric mechanism with grounding electric operation, including a grounding bracket 1. A base plate 2 is fixedly installed at one end of the grounding bracket 1, and a grounding motor mounting plate 3 is fixedly installed at the other end. A grounding transmission component 4 is arranged in the internal space enclosed by the base plate 2 and the grounding bracket 1. A grounding motor 31 is connected to the grounding motor mounting plate 3. A grounding blade spindle 5 is coaxially arranged on the base plate 2, the grounding bracket 1, the grounding motor mounting plate 3, and the grounding motor 31. The grounding blade spindle 5 passes through the base plate 2, the grounding bracket 1, and the grounding motor mounting plate 3 and extends into the interior of the grounding motor 31. One end abuts against the rotor of the grounding motor 31, and the other end is installed in the base plate 2 through a grounding blade bushing 21. A grounding operation cam 51 is sleeved on the grounding blade spindle 5 between the grounding motor 31 and the grounding motor mounting plate 3. This coaxial through-through design greatly improves the structural compactness, reduces space occupation, and ensures the precise and stable relative positions of each component, laying the foundation for the stable operation of the grounding blade spindle 5.

[0018] The grounding motor mounting plate 3 is provided with a first lower door pull rod pad 32 and a second lower door pull rod pad 33. A grounding cam support plate 34 is fixedly installed on the first lower door pull rod pad 32 and the second lower door pull rod pad 33. The grounding motor mounting plate 3 has an opening at the position corresponding to the grounding cam support plate 34. Both ends of the grounding cam support plate 34 are protruding ends 341 that extend outward through the openings. A first lower door pull rod 35 is inserted into the protruding end 341. The end of the grounding operation cam 51 abuts against the first lower door pull rod 35. When the grounding motor 31 drives the grounding operation cam 51 to rotate, the force is directly and effectively transmitted to the first lower door pull rod 35, forming a clear force transmission path, reducing energy loss, and improving the accuracy and reliability of operation.

[0019] The grounding motor mounting plate 3 is also provided with a pad support column 36. The grounding motor mounting plate 3 is connected to the upper pull rod support plate 37 through the pad support column 36. The upper pull rod support plate 37 is provided with a micro switch mounting plate 38. The micro switch mounting plate 38 is provided with a micro switch 381. The pad support column 36 provides reliable support for the upper pull rod support plate 37 to ensure its horizontal stability. The upper pull rod support plate 37 also provides a stable mounting platform for the micro switch 381, realizing real-time monitoring of the operating status of the electric mechanism.

[0020] The first lower door lever 35 has a slide plate support block 351 fixedly installed at one end near the upper lever support plate 37. The second lower door lever 39 is installed on the slide plate support block 351. The second lower door lever 39 is equipped with an interlocking baffle 391. The end of the second lower door lever 39 is provided with a lower door extension rod 392. The slide plate support block 351 positions the second lower door lever 39 to ensure its stable operation and avoid interference. The interlocking baffle 391 forms an effective interlocking mechanism. When the second lower door lever 39 moves, it moves synchronously to block the isolation operation hole associated with the second lower door lever 39, ensuring the operation sequence and safety.

[0021] The grounding transmission assembly 4 includes a grounding transmission plate 41 and a grounding knife bracket 42 built into the grounding transmission plate 41. A grounding pin 43 and a grounding short shaft 44 are snapped onto the grounding transmission plate 41. The grounding knife bracket 42 is connected to the grounding transmission plate 41 through the grounding short shaft 44. A spring guide plate 45 is provided inside the grounding knife bracket 42. One end of the spring guide plate 45 is connected to the grounding short shaft 44, and the other end is provided with a base plate shaft 47. The two ends of the base plate shaft 47 are respectively connected to the base plate 2 and the grounding bracket 1. A grounding spring 46 is wound on the spring guide plate 45. When grounding, the spring guide plate 45 deforms with the movement of the grounding short shaft 44. The grounding spring 46 stores and releases energy, playing a buffering and reset role. One end of the grounding pin 43 abuts against the grounding bracket 1, and the other end extends to the outside of the base plate 2 through the grounding groove opened in the base plate 2 and is fitted with a grounding sleeve 431, providing smooth guidance for the grounding operation.

[0022] The base plate 2 and the grounding bracket 1 are also equipped with a grounding limit plate 6. The grounding limit plate 6 is installed on the base plate 2. During the grounding operation, when the component moves to the preset position, the grounding limit plate 6 can effectively prevent it from continuing to move, preventing component damage or transmission failure caused by excessive displacement. The base plate 2 is also clamped with a base plate positioning shaft 7 to ensure the positional accuracy of the grounding transmission component 4 during installation and operation, reduce friction and wear, and improve the service life and performance reliability of the equipment.

[0023] To meet the isolation operation requirements in some scenarios, the electric mechanism integrates a conventional isolation electric operating mechanism 8 on the base plate 2, which can basically realize the circuit isolation function and help improve the overall operating performance of the electric mechanism.
