Description

Technical Field

[0001] The present invention relates to the technical field of high-voltage shore power equipment, and more particularly to a high-voltage interlocking mechanism. Background Art

[0002] Interlocking devices, as a crucial component in the high-voltage equipment industry, are widely used in high-voltage systems to ensure safety when operators operate the equipment's main circuits. Current interlocking devices primarily consist of an operating indicator panel, an operating limit block, a front drive shaft, a bevel gear, a rear drive shaft, and a rear interlocking hook. With the increasing demand for electricity in modern society, high-voltage equipment is also trending toward larger capacities. As a key component for ensuring the safe and stable operation of high-voltage equipment, conventional grounding switches on the market are no longer sufficient for the needs of new, high-capacity high-voltage equipment, necessitating larger capacities. However, the larger size of grounding switches results in a cumbersome operating mechanism, making the existing interlocking device inadequate. This interlocking device innovatively utilizes a multi-stage gear transmission, significantly reducing the torque required for operation. Furthermore, conventional grounding switches often have a large spring to ensure instantaneous closing and opening of the switch, requiring a constant hand grip on the operating handle during operation. If the hand is released, the handle rebounds, potentially injuring the operator. This interlocking device innovatively uses two sets of ratchets to prevent accidental injuries caused by the handle rebounding during operation. Summary of the Invention

DETAILED DESCRIPTION

[0028] The technical solutions of the present invention will be described in detail below by way of embodiments with reference to the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0029] The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, B exists alone, and A and B exist at the same time. The term " / and" in this article describes another type of association object relationship, indicating that two relationships can exist. For example, A / and B can mean: A exists alone, and A and B exist alone. In addition, the character " / " in this article generally indicates that the previous and subsequent associated objects are in an "or" relationship.

[0030] according to Figures 1-8As shown, a high-voltage interlocking mechanism includes an operating member, a status display member and a linkage grounding member, and the operating member, the status display member and the linkage grounding member are all arranged on a cabinet (not shown in the figure), and the status display member and the linkage grounding member are both connected to the operating member. The operating member includes a locking auxiliary member, an operating transmission member and a rotation locking member, and the locking auxiliary member and the operating transmission member are both arranged on the cabinet, and the rotation locking member is arranged on the operating transmission member. The locking auxiliary member includes a display panel and an operating panel, and the display panel is provided with a first rotating through hole and a ground knife status indication through hole, and the first rotating through hole facilitates the operating handle to pass through and then be fitted on the operating transmission member to rotate the operating transmission member. The operating panel is slidably connected to the cabinet, so that the operating panel can slide back and forth vertically on the cabinet. The operating panel is provided with a dial button, which passes through the first rotating through hole. A second rotating through hole is provided on the operating panel above the dial button. The operator can drive the operating panel to move downward by pressing the dial button, thereby making the second rotating through hole connected with the first rotating through hole, so that the operating handle can pass through and be fitted on the operating transmission member to rotate the operating transmission member.

[0031] The operating transmission member includes a transmission fixing frame and a transmission main shaft, and the transmission fixing frame is arranged on the cabinet body, and the transmission main shaft is arranged on the transmission fixing frame. The transmission fixing frame includes a front-end fixing frame and a middle-end fixing frame, and the front-end fixing frame and the middle-end fixing frame are both arranged on the cabinet body. The front-end fixing frame includes a first front-end fixing seat and a second front-end fixing seat, and the first front-end fixing seat and the second front-end fixing seat are arranged in parallel with each other on the cabinet body. The first front-end fixing seat and the second front-end fixing seat are used to fix the transmission main shaft and the rotation locking member. The middle-end fixing frame includes a first middle-end fixing seat and a second middle-end fixing seat, and the first middle-end fixing seat and the second middle-end fixing seat are arranged in parallel with each other in the cabinet body. The first middle-end fixing seat and the second middle-end fixing seat are used to fix the transmission main shaft and the status display member. One end of the transmission main shaft is horizontally disposed through the first front end fixing seat, the second front end fixing seat, the first middle end fixing seat, and the second middle end fixing seat, so that the transmission main shaft can rotate circumferentially on the first front end fixing seat, the second front end fixing seat, the first middle end fixing seat, and the second middle end fixing seat, and the axis of the transmission main shaft coincides with the axis of the first rotating through hole. The operating handle passes through the first rotating through hole and the second rotating through hole and is then mounted on the other end of the transmission main shaft to drive the transmission main shaft to rotate.

[0032] The rotation locking member includes a locking gear, a locking rotating rod, a locking torsion handle, an adjustment block, a locking shaft, a locking torsion spring, a pawl, and a first stopper. The locking gear is fixedly mounted on the transmission main shaft between the first and second front-end fixing seats. One end of the locking rotating rod passes through the second rotation through-hole and is positioned on the first and second front-end fixing seats. The axis of the locking rotating rod is parallel to the axis of the transmission main shaft, enabling the locking rotating rod to rotate on the first and second front-end fixing seats. The locking torsion handle is positioned on the other end of the locking rotating rod. The adjustment block is T-shaped, with its bottom end fixed to the locking rotating rod between the first and second front-end fixing seats, enabling the adjustment block to rotate with the locking rotating rod. The locking shaft includes a forward locking shaft and a reverse locking shaft, which are respectively positioned on the first and second front-end fixing seats on either side of the locking rotating rod. Both the forward locking shaft and the reverse locking shaft are parallel to the transmission main shaft. The locking torsion spring includes a forward locking torsion spring and a reverse locking torsion spring. The forward locking torsion spring is mounted on the forward locking shaft, and the reverse locking torsion spring is mounted on the reverse locking shaft. The pawl includes a forward pawl and a reverse pawl. One end of the forward pawl is fixedly mounted on the forward locking shaft, and the forward pawl is connected to one end of the forward locking torsion spring. At the same time, the other end of the forward pawl is embedded in the tooth groove of the locking gear. One end of the reverse pawl is mounted on the reverse locking shaft, and the reverse pawl is connected to one end of the reverse locking torsion spring. At the same time, the other end of the reverse pawl is embedded in the tooth groove of the locking gear. The forward pawl and the reverse pawl respectively form a ratchet mechanism with the locking gear. The first limit block is fan-shaped. The center of the first limit block is fixedly mounted on the locking rotating rod, and the axis of the first limit block is parallel to the axis of the locking rotating shaft. The first limit block can limit the forward and reverse rotation angles of the locking rotating shaft. When the locking twist handle drives the adjustment block to rotate forward by a certain angle through the locking rotating shaft, the other end of the reverse pawl will be pushed out from the tooth groove of the locking gear to facilitate the forward rotation of the transmission main shaft; and when the transmission main shaft is driven by the operating handle to rotate forward by a certain angle and needs to be turned back, the rotating locking twist handle can be released to re-embed the other end of the reverse pawl into the tooth groove of the locking gear to prevent the operating handle from injuring the operator's hand when it is driven by the transmission main shaft to rebound.When the locking twist handle drives the adjustment block to rotate in the opposite direction by a certain angle through the locking rotating shaft, the other end of the positive pawl will be pushed out from the tooth groove of the locking gear to facilitate the reverse rotation of the transmission main shaft; and when the transmission main shaft is driven by the operating handle to rotate in the opposite direction by a certain angle and needs to be turned back, the rotating locking twist handle can be released to re-embed the other end of the positive pawl into the tooth groove of the locking gear to prevent the operating handle from injuring the operator's hand when it is driven by the transmission main shaft to rebound.

[0033] The status display component includes a status indication shaft, a reduction transmission component and an electric shock linkage component. The reduction transmission component is arranged on the middle-end fixed frame, the status indication shaft is arranged on the reduction transmission component, and the electric shock linkage component is arranged on the status indication shaft. One end of the status indication shaft is arranged through the first middle-end fixed seat and the second middle-end fixed seat, so that the status indication shaft can rotate on the first middle-end fixed seat and the second middle-end fixed seat. The reduction transmission component includes an active reduction gear, a relay reduction gear and a driven reduction gear. The two ends of the rotating shaft of the active reduction gear are respectively arranged through the first middle-end fixed seat and the second middle-end fixed seat, and the active reduction gear is engaged with the gear teeth on the transmission main shaft, and the diameter of the active reduction gear is larger than the gear teeth diameter. The two ends of the rotating shaft of the relay reduction gear are respectively arranged through the first middle-end fixed seat and the second middle-end fixed seat, and the relay reduction gear is engaged with the active reduction gear, and the diameter of the relay reduction gear is larger than the diameter of the active reduction gear. The driven reduction gear is fixedly mounted on the status indicating shaft between the first and second middle end fixing seats, and is meshed with the relay reduction gear. The diameter of the driven reduction gear is no larger than that of the relay reduction gear. This allows the rotational speed of the transmission main shaft to be reduced in sequence by the driving reduction gear, the relay reduction gear, and the driven reduction gear before being transmitted to the status indicating shaft.

[0034] The electric shock linkage includes a first cam piece, a rotation limit piece, a second limit block, a ground switch status display panel and an electromagnetic lock. The first cam piece is fixedly arranged on the status indication shaft. The first cam piece rotates with the rotation of the status indication shaft. When the status indication shaft drives the first cam piece to rotate 90 degrees, it presses and triggers the auxiliary contact, so that the auxiliary contact is connected to output an electrical signal of the grounding switch closing to the outside. Conversely, it can output an electrical signal of the grounding switch opening to the outside for the logic control of the switch cabinet. The rotation limit piece is fan-shaped, and the central angle of the rotation limit piece is greater than 180 degrees and less than 270 degrees. The rotation limit piece is fixedly mounted on the status indication shaft. The second limit block is set on the cabinet body. When the rotation limit piece rotates forward or reversely with the status indication shaft to 90 degrees, it will be blocked by the second limit block to prevent the status indication shaft from rotating too much and crushing the auxiliary contact. The ground switch status display panel is provided with the words "closed" and "opened," with the central angles of "closed" and "opened" forming a 90-degree angle. The ground switch status display panel is fixed to one end of the status indicator shaft and rotates with the status indicator shaft, allowing the words "closed" and "opened" to be visible to staff through the ground switch status indicator hole, thereby preventing accidents caused by misoperation.

[0035] The electromagnetic lock is mounted on the cabinet below the operating panel. Its electrical signal comes from the high-voltage equipment control circuit. When the switchgear's main circuit is energized, the electromagnetic lock is de-energized, blocking the operating panel from moving downward. This prevents operators from inserting the operating handle through the first and second rotation holes and then attaching it to the main drive shaft for rotation. Only when the switchgear's main circuit is de-energized does the electromagnetic lock retract, allowing the grounding switch to be operated. This electrical logic interlocks the grounding switch, further preventing accidents caused by misoperation.

[0036] The linkage grounding member includes a first bevel gear, a relay gear member, a rear door interlock shaft, and a second bevel gear. The first bevel gear is fixedly mounted on one end of the transmission main shaft. The relay gear member includes a gear relay frame, a relay transmission shaft, and a bevel gear. One end of the gear relay frame is horizontally fixed on the grounding switch. One end of the relay transmission shaft is passed through the other end of the gear relay frame, so that the relay transmission shaft can rotate on the gear relay frame. The bevel gear is fixedly mounted on the relay transmission shaft, and the bevel gear is meshed with the first bevel gear. When the transmission main shaft drives the first bevel gear to rotate, it will be transmitted to the grounding switch through the bevel gear and the gear transmission shaft, thereby closing and opening the grounding switch. Since the spring flipping torque of the large-capacity grounding switch is particularly large, the transmission is carried out through the bevel gear and the first bevel gear, which significantly reduces the rotational torque of the transmission main shaft and significantly facilitates personnel operation. The second bevel gear is mounted on the rear door interlock shaft and meshes with the bevel gear to transmit power to the rear door interlock shaft via the bevel gear. The rear door interlock shaft interlocks the rear door panel of the high-voltage equipment via the rear door interlock hook. The rear door interlock hook is unlocked only when the grounding switch is closed. The rear door panel can then be opened to prevent operators from accidentally entering the live compartment.

[0037] The high-voltage interlocking mechanism is implemented as follows:

[0038] 1) When the main circuit of the high-voltage equipment is not energized, the electromagnetic lock is energized and retracted;

[0039] 2) Press the dial button on the operation panel to connect the second rotating through hole with the first rotating through hole, then insert the operating handle. The operating handle drives the transmission main shaft to rotate clockwise for 3 turns to close the grounding switch;

[0040] 3) During the rotation of the transmission main shaft, the status indicator shaft is driven to rotate through the reduction transmission member. When the transmission main shaft rotates exactly 3 turns and the grounding switch is closed, the status indicator shaft rotates exactly 1 / 4 turn, and the status indicator changes from "0" to "1". The auxiliary contact is pressed and connected by the first cam piece on the status indicator shaft, and an electrical signal indicating that the grounding switch is closed is output to the outside.

[0041] 4) The bevel gear is driven by the transmission main shaft through the first bevel gear to rotate, and the grounding switch is driven by the bevel gear to rotate and slowly close;

[0042] 5) During the closing process of the grounding switch, the rear door interlock shaft rotates along with the transmission main shaft. When the grounding knife is closed, the rear door interlock shaft rotates to the unlocked position through the rear door interlock hook. Only then can the rear door panel of the high-voltage equipment be opened.

[0043] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
