Description

Technical Field

[0001] The invention relates to the technical field of high-voltage switches and relates to a novel three-position operating mechanism. Background Art

[0002] High-voltage vacuum circuit breakers, high-voltage disconnectors, and earthing switches are widely used in power transmission and distribution systems. High-voltage vacuum circuit breaker combination switches are a new type of combined electrical appliance, primarily used as core components in pneumatic switchgear. They feature high integration, compact size, simple structure, and high reliability. Existing pneumatic switchgear typically have a three-position operating mechanism, such as the utility model disclosed in Chinese patent publication number CN217544455U, with an authorization announcement date of October 4, 2022, and the designation "A Three-Position Disconnector Operating Mechanism." Another example is the invention disclosed in Chinese patent publication number CN105428137A, with an application publication date of March 23, 2016, and the designation "A Three-Position Load Switch Operating Mechanism for a Pneumatic Switchgear." However, the production processes of these and similar products are complex, resulting in high manufacturing and material costs, leading to higher prices and poor market competitiveness. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the present invention aims to provide a novel three-station operating mechanism in the art, thereby resolving the technical problems of existing similar products, such as the complex production process, high manufacturing and material costs, resulting in high product prices and poor market competitiveness. This objective is achieved through the following technical solution.

[0004] A novel three-station operating mechanism is a splint-type mechanism, comprising an energy storage spring assembly, a drive plate assembly, a mounting plate assembly, a drive shaft assembly, an operating handle assembly, a bearing sleeve, a rear support plate, a support sleeve, a support column, a front support plate, and a panel. The panel has an isolation operating hole and a grounding operating hole. The drive plate of the drive plate assembly is L-shaped, and the drive plate of the drive plate assembly is fixed to one end of the drive shaft of the drive shaft assembly through an elastic cylindrical pin. The corresponding axial holes of the mounting plate assembly, the front support plate, and the rear support plate are respectively installed on the drive shaft of the drive shaft assembly through bearing sleeves. The drive shaft of the drive shaft assembly is provided with an energy storage spring assembly, and the fan-shaped plate of the energy storage spring assembly is provided with an energy storage torsion spring. The operating shaft of the energy storage spring assembly is arranged at the other end of the drive shaft of the drive shaft assembly. The operating shaft of the energy storage spring assembly extends out of the front support plate and is located below the panel of the front support plate. The mounting plate of the mounting plate assembly is connected to the rear support plate and the front support plate on both sides through support sleeves and support columns. The key points of its structural design are that the driving plate of the driving plate assembly and the two ends of the energy storage torsion spring of the energy storage spring assembly are embedded together, the horizontal plate at one end of the driving plate is limited between the two ends of the energy storage torsion spring, the width of the horizontal plate of the driving plate is smaller than the distance between the two ends of the energy storage spring, and the other end of the horizontal plate of the driving plate is provided with a gusset plate arranged outwardly in a mirror-symmetrical manner. The opposite ends of the two gusset plates are respectively fixed to the driving plate through pin shafts, and the other ends of the gusset plates are respectively provided with arcuate edges, and the end corners of one side of the arcuate edge corresponding to the horizontal plate of the driving plate are respectively provided with positioning pins, and the end corners of the other end of the gusset plate are respectively fixed to the corresponding end of the driving plate through positioning pins. The corner grooves are symmetrically arranged on both sides, and the other end corners of the symmetrical buckle plates of the corner grooves extend out of the arc-shaped edges of the buckle plates respectively; a roller sleeve is provided at the bottom of the drive plate assembly on the other side of the drive shaft of the drive shaft assembly, and one end of the output shaft extends out of the mounting plate of the mounting plate assembly. The output crank arm at one end of the output shaft is connected to the drive crank arm at the drive shaft of the drive shaft assembly through a connecting plate. At the same time, the drive crank arm is connected to the fan-shaped plate on one side of the drive plate assembly of the energy storage spring assembly; the mounting plates corresponding to the buckle plates are symmetrically provided with the first limiting rollers respectively, and the drive shaft and one end of the output shaft in the rear support plate and the front support plate are square shafts respectively. The above structure mainly plays the same role as the energy storage spring in similar products through the interaction between the energy storage torsion spring and the drive plate assembly, thereby reducing the overall volume and production costs while ensuring stability and safety.

[0005] The driving plates between the gusset plates of the driving plate assembly are provided with gusset plate torsion springs, the two ends of which respectively abut against the gusset plates at the pin shafts on both sides. The gusset plate torsion springs facilitate the resetting of the gusset plates on both sides.

[0006] The angle between the center of the torsion spring on the drive plate assembly and the center of the drive plate's cross plate is 135 degrees, the angle between the center of the drive plate's cross plate and the center of the pin is 115 degrees, and the angle between the center of the drive plate's cross plate and the center of the locating pin is 82 degrees. These angles are subject to a ±5-degree correction range.

[0007] One end of the fan-shaped plate of the energy storage spring assembly is T-shaped and extends out of the bottom outer diameter of the energy storage torsion spring. One side of the T-shaped end of the fan-shaped plate is connected to the driving crank arm and the connecting plate.

[0008] The edge of one side of the gusset plate on the driving plate of the driving plate assembly is arc-shaped, and the arc-shaped edge of one side of the gusset plate is larger than the arc-shaped edge of one side of the pin shaft. The above structure facilitates the outer side of the gusset plate to play a limiting role through the arc-shaped edge.

[0009] Two second limiting rollers are symmetrically positioned between the two first limiting rollers on the mounting plate. The mounting plate, outboard of the first limiting rollers, is provided with symmetrically positioned limiting pins. The first limiting rollers, limiting pins, and second limiting rollers are symmetrically positioned on one side of the drive shaft assembly's drive shaft core. This structure, through the second limiting rollers, provides a secondary limiting function, further enhancing overall stability and safety.

[0010] The angle between the two second limiting rollers of the mounting plate assembly is 47 degrees, the angle between the two first limiting rollers is 109 degrees, and the angle between the limiting pins is 172 degrees. The above angles have a correction range of ±5 degrees.

[0011] The arc-shaped hole on one side of the panel is the isolation operation hole and the grounding operation hole of the panel. The upper part of the arc-shaped hole is aligned with the open edge groove at one end of the operation hole baffle, and the other end of the operation hole baffle is fixed to the panel through a mounting column.

[0012] The operating principle of the operating mechanism is as follows: after the operating handle assembly is inserted into the operating hole of the panel, the energy storage spring assembly is stored in the counterclockwise direction, and the fan-shaped plate of the energy storage spring assembly also rotates counterclockwise. When the fan-shaped plate rotates to the buckle plate of the drive plate assembly, the buckle plate is pushed toward the axis core direction of the drive shaft assembly, so that the buckle plate is separated from the limit roller of the mounting plate assembly. Immediately after the tripping, under the potential energy of the energy storage torsion spring, the drive shaft assembly rotates rapidly in the counterclockwise direction, and the output is toggled on the isolation switch through the roller sleeve of the drive shaft assembly. When the cam is in the grounding position, the energy storage spring assembly stores energy in a clockwise direction, and the fan-shaped plate of the energy storage spring assembly also rotates in a clockwise direction. When the fan-shaped plate rotates to the buckle plate of the drive plate assembly, the buckle plate is pushed toward the axis core direction of the drive shaft assembly, so that the buckle plate is separated from the limit roller on the mounting plate assembly. Immediately after the tripping, under the action of the potential energy of the energy storage torsion spring, the drive shaft assembly rotates rapidly in the clockwise direction, and the output is toggled through the roller sleeve of the drive shaft assembly to make the grounding disconnect state.

[0013] The present invention has a reasonable overall design, reliable structure, convenient production and assembly, small size and low cost; it is suitable for use as a three-position operating mechanism in an inflatable cabinet, and is a structural improvement of similar products.

[0028] Now, the structure and use of the present invention will be further described in conjunction with the accompanying drawings. Figures 1-13As shown, the operating mechanism is a clamping mechanism, including an energy storage spring assembly 1, a drive plate assembly 2, a mounting plate assembly 3, a drive shaft assembly 4, an operating handle assembly 11, and a bearing sleeve 5, a rear support plate 6, a support sleeve 7, a support column 8, a front support plate 9, and a panel 10. The panel has an isolation operation hole and a grounding operation hole. The drive plate 204 of the drive plate assembly is L-shaped. The drive plate of the drive plate assembly is fixed to one end of the drive shaft 401 of the drive shaft assembly through an elastic cylindrical pin. The corresponding axial holes of the mounting plate assembly, the front support plate, and the rear support plate are respectively installed on the drive shaft of the drive shaft assembly through bearing sleeves. The drive shaft of the drive shaft assembly is provided with an energy storage spring assembly. The fan-shaped plate 102 of the energy storage spring assembly is provided with an energy storage torsion spring 101. The operating shaft 103 of the energy storage spring assembly is arranged at the other end of the drive shaft of the drive shaft assembly. The operating shaft of the energy storage spring assembly extends out of the front support plate and is located below the panel of the front support plate. The mounting plate 301 of the mounting plate assembly is connected to the rear support plate and the front support plate on both sides through the support sleeve and the support column. The driving plate of the driving plate assembly and the two ends of the energy storage torsion spring of the energy storage spring assembly are embedded together, the horizontal plate at one end of the driving plate is limited between the two ends of the energy storage torsion spring, the width of the horizontal plate of the driving plate is smaller than the distance between the two ends of the energy storage spring, and the other end of the horizontal plate of the driving plate is provided with a gusset plate 201 that is mirror-symmetrically arranged outwards, and the opposite ends of the two gusset plates are respectively fixed to the driving plate through pin shafts 202, and the other ends of the gusset plates are respectively provided with arcuate edges, and the end corners on one side of the arcuate edges corresponding to the horizontal plate at the driving plate are respectively provided with locating pins, and the end corners at the other end of the gusset plate are respectively fixed to the corner grooves symmetrically arranged on both sides of the corresponding ends of the driving plate through locating pins. The other end corner of the gusset plate with symmetrical angle grooves extends out of the arc-shaped edge of the gusset plate respectively; a roller sleeve 402 is provided at the bottom of the driving plate assembly on the other side of the driving axis of the driving shaft assembly, and one end of the output shaft 12 extends out of the mounting plate 301 of the mounting plate assembly, and the output crank arm 13 at one end of the output shaft is connected to the driving crank arm 15 at the driving shaft of the driving shaft assembly through the connecting plate 14. At the same time, the driving crank arm is connected to the fan-shaped plate on one side of the driving plate assembly with the energy storage spring assembly; the mounting plates corresponding to the gusset plates are respectively symmetrically provided with the first limiting rollers 302, and the driving shaft and one end of the output shaft in the rear support plate and the front support plate are respectively square axes.

[0029] The drive plate between the gussets of the above-mentioned drive plate assembly is provided with a gusset torsion spring 203, and the two ends of the gusset torsion spring are respectively against the gussets at the pins 202 on both sides. The angle between the center of the gusset torsion spring of the drive plate assembly and the middle of the transverse plate of the drive plate is 135 degrees, the angle between the middle of the transverse plate of the drive plate and the center of the pin is 115 degrees, and the angle between the middle of the transverse plate of the drive plate and the center of the locating pin is 82 degrees. One end of the fan-shaped plate of the energy storage spring assembly is T-shaped and extends out of the bottom outer diameter of the energy storage torsion spring. One side of the T-shaped end of the fan-shaped plate is connected to the driving crank arm and the connecting plate. The edge of one side of the gusset on the drive plate of the drive plate assembly is arc-shaped, and the arc edge on one side of the gusset is larger than the arc edge on one side of the pin. Two second limiting rollers 304 are symmetrically arranged between the two first limiting rollers on the mounting plate. The mounting plates outside the first limiting rollers are respectively provided with symmetrically arranged limiting pins 303. The first limiting roller, limiting pin, and second limiting roller are symmetrically arranged on one side with the axis core of the drive shaft of the drive shaft assembly as the center of the circle. The angle between the two second limiting rollers of the mounting plate assembly is 47 degrees, the angle between the two first limiting rollers is 109 degrees, and the angle between the limiting pins is 172 degrees. The arc-shaped hole on one side of the panel serves as the isolation operation hole and the grounding operation hole of the panel. The top of the arc-shaped hole is aligned with the open edge groove at one end of the operation hole baffle 16. The other end of the operation hole baffle is fixed to the panel via a mounting column.

[0030] All of the above components and parts are installed on the driving shaft of the driving shaft assembly, wherein the driving plate assembly is fastened together with the corresponding hole on the driving shaft of the driving shaft assembly through an elastic cylindrical pin; and the driving plate of the driving plate assembly is embedded with both ends of the energy storage torsion spring of the energy storage spring assembly, and acts as a force application point when the torsion spring stores energy (the torsion spring stores energy in a clockwise or counterclockwise direction according to the different functions of the three stations, and the driving plate applies force synchronously, such as 4, Figure 5 (As shown). The corresponding axial holes of the mounting plate assembly, front support plate, and rear support plate are respectively mounted on the drive shaft of the drive shaft assembly through bearing sleeves. They are fastened together by support columns and support sleeves, as well as screws, spring washers, and flat washers to form a single unit. When the operating mechanism is in operation, the operating handle of the operating handle assembly is inserted through the isolation operation hole or grounding operation hole on the mechanism panel to operate the drive shaft assembly. The two are interlocked, meaning that grounding operation cannot be performed after the isolation switch is closed, and isolation operation cannot be performed after grounding operation is closed, to ensure safety.

[0031] like Figures 9-11 The diagrams show three different states of the mechanism. The operating principle of the operating mechanism is as follows: When the operating handle assembly 11 is inserted into the operating hole of the panel 10, the energy storage spring assembly 1 is charged in the counterclockwise direction (as shown in FIG. Figure 4As shown), the sector plate 102 of the energy storage spring assembly also rotates counterclockwise. When the sector plate rotates to the gusset plate 20 of the drive plate assembly 2, it pushes the gusset plate toward the axis of the drive shaft assembly 4, so that the gusset plate is separated from the limiting roller 302 of the mounting plate assembly 3 (as shown). Figure 6 As shown), immediately after the trip, under the potential energy of the energy storage torsion spring, the drive shaft assembly rotates rapidly in the counterclockwise direction, outputs and toggles the output crank arm 13 on the disconnector through the roller sleeve 402 of the drive shaft assembly to ground the disconnector; similarly, when the mechanism is in the grounding position, the energy storage spring assembly stores energy in the clockwise direction (as shown). Figure 5 As shown), the fan-shaped plate of the energy storage spring assembly also rotates clockwise. When the fan-shaped plate rotates to the gusset plate of the drive plate assembly, it pushes the gusset plate toward the axis of the drive shaft assembly, so that the gusset plate is separated from the limiting roller on the mounting plate assembly (as shown). Figure 7 As shown in the figure), immediately after tripping, under the potential energy of the energy storage torsion spring, the drive shaft assembly rotates rapidly in the clockwise direction, and the output and the output arm on the disconnector are toggled through the roller sleeve of the drive shaft assembly to make the grounding state disconnected.
