Description

Technical Field

[0001] This invention relates to the field of one-button sequential control devices, specifically a one-button sequential control device for an electric operating mechanism. Background Technology

[0002] Currently, in GIS (Gas Insulated Metal Enclosed Switchgear), the isolating grounding switch is widely driven by an electric mechanism. To accurately transmit the opening and closing signals of the electric mechanism and ensure the safe and stable operation of the switchgear, existing technologies typically include an auxiliary switch in the electric mechanism, along with a one-button sequential control device to provide signal feedback on the opening and closing status.

[0003] However, existing one-button sequential control devices mostly adopt a structure that combines a single set of transmission wheels with a micro switch, which is suitable for signal acquisition of a single output angle and cannot meet the one-button sequential control requirements of electric mechanisms to achieve dual output angles (such as main angle and secondary angle).

[0004] Therefore, providing a one-button sequential control device for an electric operating mechanism is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a one-button sequential control device for an electric operating mechanism, which can meet the dual output angle requirements of the electric mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A one-button sequential control device for an electric operating mechanism includes a fixed plate, an output shaft, a main drive wheel, a secondary drive wheel, a fixed shaft, a main driven wheel, a secondary driven wheel, a main drive micro switch group, and a secondary drive micro switch group. The output shaft is rotatably connected to the fixed plate. The main drive wheel and the secondary drive wheel are both sleeved and fixed on the output shaft and arranged in layers. The fixed shaft is fixed to the fixed plate. The main driven wheel and the secondary driven wheel are rotatably connected to the fixed shaft and arranged in layers. The main driven wheel and the secondary driven wheel are connected together by a fixing pin. The main driven wheel and the secondary driven wheel are connected to the fixed plate. The main drive wheel is connected by gear meshing, and the secondary driven wheel is connected to the secondary drive wheel by gear meshing. The main and driven wheels have a multi-tooth structure on their clockwise meshing surface and a missing-tooth structure on their counterclockwise meshing surface. The secondary driven wheel has a multi-tooth structure on its counterclockwise meshing surface and a missing-tooth structure on its clockwise meshing surface. The main drive micro switch assembly is mounted on the fixed plate and corresponds to the position of the main and driven wheels. The secondary drive micro switch assembly is mounted on the fixed plate and corresponds to the position of the secondary driven wheel.

[0008] Furthermore, the driving and driven wheels include a main wheel body, a main sector tooth, and a main connecting plate connected as one unit; the driven and driven wheels include a driven and driven wheel body, a driven and driven sector tooth, and a driven and driven plate connected as one unit. The main wheel body and the driven and driven wheel bodies are rotatably connected to the fixed shaft and arranged in layers. The main connecting plate and the driven and driven plate are connected by the fixing pin. The side of the main wheel body that connects to the right side of the main sector tooth is an inclined plane to form a main release space. The side of the driven and driven wheel body that connects to the left side of the driven and driven sector tooth is an inclined plane to form a secondary release space. The circumferential side of the main sector tooth is provided with a first main tooth and a second main tooth spaced apart. The main gear and the secondary sector gear have a first secondary tooth and a second secondary tooth spaced apart on their circumferential side surfaces. The first main tooth and the first secondary tooth are vertically opposite each other, and the second main tooth and the second secondary tooth are symmetrically distributed horizontally. The second main tooth is located below the secondary release space, and the second secondary tooth is located above the main release space. The main drive wheel has two main drive teeth spaced apart on its circumferential side surfaces, which mesh with the first main tooth and the second main tooth respectively when rotating counterclockwise. The secondary drive wheel has two secondary drive teeth spaced apart on its circumferential side surfaces, which mesh with the first secondary tooth and the second secondary tooth respectively when rotating clockwise.

[0009] Furthermore, the main drive micro switch group includes a first main drive micro switch and a second main drive micro switch. The first main drive micro switch and the second main drive micro switch are located on both sides of the main driven wheel and are diagonally distributed. The drive rod of the first main drive micro switch corresponds to the circumferential side of the main wheel body near the inclined plane, and the drive rod of the second main drive micro switch corresponds to the side of the main connecting plate. The auxiliary drive micro switch group includes a first auxiliary drive micro switch and a second auxiliary drive micro switch. The first auxiliary drive micro switch and the second auxiliary drive micro switch are located on both sides of the auxiliary driven wheel and are diagonally distributed. The drive rod of the first auxiliary drive micro switch corresponds to the circumferential side of the auxiliary wheel body near the inclined plane, and the drive rod of the second auxiliary drive micro switch corresponds to the side of the auxiliary connecting plate.

[0010] Furthermore, it also includes a damping spring, with a retaining ring at the top of the fixed shaft, and the damping spring is sleeved on the fixed shaft and pressed between the retaining ring and the secondary driven wheel.

[0011] Therefore, the present invention provides a one-button sequential control device for an electric operating mechanism, which has the following advantages compared with the prior art: 1) Achieve precise signal feedback from dual output angles By fixing the main drive wheel and the auxiliary drive wheel to the output shaft in two layers, and forming two independent gear meshing transmission paths with the main driven wheel and the auxiliary driven wheel respectively, the main driven wheel and the auxiliary driven wheel are locked in position by fixing pins and cooperate with corresponding microswitches. When the output shaft rotates counterclockwise to output the main angle, the main drive path triggers the corresponding microswitch state change through the multi-tooth structure, while the auxiliary drive path remains unchanged due to the toothless structure design. When the output shaft rotates clockwise to output the secondary angle, the secondary drive path triggers the corresponding microswitch state change through the multi-tooth structure, while the main drive path remains unchanged due to the toothless structure design. This allows the same device to accurately distinguish and feedback the opening and closing signals of the main angle and the secondary angle, avoiding signal confusion or misjudgment. 2) One-click sequential control to adapt to any output angle requirement Employing a dual-gear transmission design, the driving and driven wheels are respectively meshed with their corresponding transmission wheels via gears. Multiple or missing teeth are incorporated in specific directions, allowing for flexible setting of signal triggering timing under different rotational directions. Leveraging the precise angular displacement transmission characteristics of gear meshing, and combined with the placement of microswitches, the number of teeth, tooth profile, or microswitch mounting position can be adjusted according to actual needs. This adapts to the one-button sequential control signal transmission requirements of electric mechanisms at any output angle, without requiring replacement of core components, thus offering strong versatility. 3) Compact structure and high integration The main drive wheel and the auxiliary drive wheel are fixed to the output shaft in two layers, and the main driven wheel and the auxiliary driven wheel are fixed to the fixed shaft in two layers. Two sets of micro switches are arranged in layers on the same fixed plate. The overall structure is highly integrated, compact, and occupies little space. It is easy to install and arrange inside the electric mechanism, which is conducive to the miniaturization design of switchgear. 4) Reliable signal output and strong anti-interference capability The signal output method adopts pure mechanical gear transmission and direct triggering of micro switch, without relying on electronic sensors or complex logic judgment, effectively avoiding problems such as electromagnetic interference and signal drift. The gear meshing transmission has good repeatability and stability, and can maintain accurate angular displacement transmission for a long time, ensuring that the micro switch operates accurately at the set angle. The signal output has high reliability and long service life. 5) Simplify installation and debugging, and reduce manufacturing costs. Compared to existing technologies that require multiple independent transmission mechanisms or complex electrical logic to accommodate dual output angles, this method achieves dual signal acquisition through a single mechanical structure. It has fewer parts, clear assembly relationships, and is easy to install and debug, effectively reducing manufacturing costs and improving production efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] like Figure 1-3 As shown, this embodiment of the invention discloses a one-button sequential control device for an electric operating mechanism, including a fixed plate 1, an output shaft 2, a main drive wheel 3, a secondary drive wheel 4, a fixed shaft 5, a main driven wheel 6, a secondary driven wheel 7, a main drive micro switch group, and a secondary drive micro switch group. The electric operating mechanism is drivenly connected to the output shaft 2; the output shaft 2 is rotatably connected to the fixed plate 1; the main drive wheel 3 and the secondary drive wheel 4 are both sleeved and fixed on the output shaft 2 and arranged in layers; the fixed shaft 5 is fixed on the fixed plate 1; the main driven wheel 6 and the secondary driven wheel 7 are respectively rotatably connected to the fixed shaft 5 and arranged in layers; the main driven wheel 6 and the secondary driven wheel 7... The main and driven wheels 6 and main drive wheel 3 are connected by a fixing pin 8; the driven wheel 7 and driven wheel 4 are connected by a gear meshing, and the driven wheel 6 has a multi-tooth structure on its clockwise meshing surface and a missing-tooth structure on its counterclockwise meshing surface; the driven wheel 7 has a multi-tooth structure on its counterclockwise meshing surface and a missing-tooth structure on its clockwise meshing surface; the main drive micro switch assembly is mounted on the fixing plate 1 and corresponds to the position of the driven wheel 6; the driven micro switch assembly is mounted on the fixing plate 1 and corresponds to the position of the driven wheel 7. This invention, through the combination of dual gear transmission and multi-tooth and missing-tooth structures, achieves precise and reliable signal feedback for any dual output angle of the electric mechanism with a compact mechanical device, meeting the dual output angle requirements of the electric mechanism.

[0016] Specifically, the driving and driven wheels 6 include a main wheel body 61, a main sector tooth 62, and a main connecting plate 63 connected as one unit. The driven and driven wheels include a secondary wheel body, a secondary sector tooth, and a secondary connecting plate connected as one unit. The main wheel body 61 and the secondary wheel body are rotatably connected to the fixed shaft 5 and arranged in layers. The main connecting plate 63 and the secondary connecting plate are connected by a fixing pin 8. The side of the main wheel body 61 that connects with the right side of the main sector tooth 62 is an inclined plane to form a main release space. The side of the secondary wheel body that connects with the left side of the secondary sector tooth is an inclined plane to form a secondary release space. The circumferential side of the main sector tooth 62 is provided with spaced first main teeth 621. The second main tooth 622 and the secondary sector tooth have spaced first and second secondary teeth on their circumferential side surfaces. The first main tooth 621 and the first secondary tooth are vertically aligned, and the second main tooth 622 and the second secondary tooth are symmetrically distributed horizontally. The second main tooth 622 is located below the secondary release space, and the second secondary tooth is located above the main release space. The main drive wheel 3 has two spaced main drive teeth on its circumferential side surfaces, which mesh with the first main tooth 621 and the second main tooth 622 respectively when rotating counterclockwise. The secondary drive wheel has two spaced secondary drive teeth on its circumferential side surfaces, which mesh with the first secondary tooth and the second secondary tooth respectively when rotating clockwise.

[0017] Specifically, the main drive micro switch group includes a first main drive micro switch 9 and a second main drive micro switch 10. The first main drive micro switch 9 and the second main drive micro switch 10 are located on both sides of the main driven wheel 6 and are diagonally distributed. The drive rod of the first main drive micro switch 9 corresponds to the circumferential side of the main wheel body 61 near the inclined plane, and the drive rod of the second main drive micro switch 10 corresponds to the side of the main connecting plate 63. The auxiliary drive micro switch group includes a first auxiliary drive micro switch 11 and a second auxiliary drive micro switch 12. The first auxiliary drive micro switch 11 and the second auxiliary drive micro switch 12 are located on both sides of the auxiliary driven wheel 7 and are diagonally distributed. The drive rod of the first auxiliary drive micro switch 11 corresponds to the circumferential side of the auxiliary wheel body near the inclined plane, and the drive rod of the second auxiliary drive micro switch 12 corresponds to the side of the auxiliary connecting plate.

[0018] To further optimize the technical solution of the present invention, a damping spring 13 is also included. A retaining ring is provided at the top end of the fixed shaft 5. The damping spring 13 is sleeved on the fixed shaft 5 and pressed between the retaining ring and the secondary driven wheel 7 to increase damping.

[0019] Working principle of the invention: The counterclockwise rotation transmission process of output shaft 2: In the initial position, the first main drive micro switch 9 and the first auxiliary drive micro switch 11 are both in the compressed position (i.e., the drive rod of the first main drive micro switch 9 is pressed against the circumferential side of the main wheel body 61 near the inclined plane, and the drive rod of the first auxiliary drive micro switch 11 is pressed against the circumferential side of the auxiliary wheel body near the inclined plane), and the second main drive micro switch 10 and the second auxiliary drive micro switch 12 are in the released state (the drive rod of the second main drive micro switch 10 is separated from the side of the main connecting plate 63, and the drive rod of the second auxiliary drive micro switch 12 is separated from the side of the auxiliary connecting plate).

[0020] When the electric operating mechanism outputs the main angle by rotating the output shaft 2 counterclockwise, the output shaft 2 drives the main drive wheel 3 and the auxiliary drive wheel 4 to rotate counterclockwise. The main drive wheel 3 drives the main driven wheel 6 to rotate clockwise (the drive rod of the first main drive micro switch 9 is close to the main release space direction), and the auxiliary drive wheel 4 drives the auxiliary driven wheel 7 to rotate clockwise (the drive rod of the first auxiliary drive micro switch 11 is away from the auxiliary release space direction). Because the auxiliary driven wheel 7 has a tooth-deficient structure design in the clockwise direction, when it rotates clockwise, the auxiliary drive teeth on the other side of the auxiliary drive wheel 4 cannot mesh with it. Thus, when the output shaft 2 rotates through the main output angle, the auxiliary driven wheel 7 and the main driven wheel 6 rotate through the same angle. The first auxiliary drive micro switch 11 is still in the compressed position, and the second auxiliary drive micro switch 12 is still in the released state. Due to the multi-tooth structure design of the main and driven wheels 6 in the clockwise direction, when the output shaft 2 rotates through the main output angle, the main drive teeth on the other side of the main drive wheel 3 can mesh with the second main teeth 622, causing the main and driven wheels 6 to rotate through the main output angle. This causes the drive rod of the first main drive micro switch 9 to enter the main release space, changing from the compressed state to the released state. The drive rod of the second main drive micro switch 10 is in close contact with the side of the main connecting plate 63, changing from the released state to the compressed state.

[0021] The clockwise rotation of output shaft 2 is a transmission process: In the initial position, the first main drive micro switch 9 and the first auxiliary drive micro switch 11 are both in the compressed position, while the second main drive micro switch 10 and the second auxiliary drive micro switch 12 are in the released state.

[0022] When the electric operating mechanism outputs the secondary angle by rotating the output shaft 2 clockwise, the output shaft 2 drives the main drive wheel 3 and the secondary drive wheel 4 to rotate clockwise. The main drive wheel 3 drives the main driven wheel 6 to rotate counterclockwise (the drive rod of the first main drive micro switch 9 moves away from the main release space direction), and the secondary drive wheel 4 drives the secondary driven wheel 7 to rotate counterclockwise (the drive rod of the first secondary drive micro switch 11 moves closer to the secondary release space direction). Because the main and driven wheels 6 have a tooth-deficient structure in the counterclockwise direction, when they rotate counterclockwise, the main drive teeth on the other side of the main drive wheel 3 cannot mesh with them; when the output shaft 2 rotates through the secondary output angle, the main and driven wheels 6 and the secondary driven wheel 7 rotate through the same angle, the first main drive micro switch 9 is still in the compressed position, and the second main drive micro switch 10 is still in the released state. Because the secondary driven wheel 7 has a multi-tooth structure design in the counterclockwise direction, when the output shaft 2 rotates through the secondary output angle, the secondary transmission teeth on the other side of the secondary transmission wheel 4 can mesh with the second secondary teeth, causing the secondary driven wheel 7 to rotate the main output angle, so that the drive rod of the first secondary transmission micro switch 11 enters the secondary release space and changes from the compressed state to the released state, and the second secondary transmission micro switch 12 changes from the released state to the compressed state.
