Description

Technical Field

[0001] This invention belongs to the field of low-voltage electrical technology, specifically relating to an automatic transfer switch operation mode control component. Background Technology

[0002] With social development, people's requirements for the power grid and its transmission and distribution processes are gradually increasing. In some important power distribution situations, the power supply system needs to ensure continuity to ensure electricity safety and that production and daily life are not interrupted. Automatic transfer switches have two or more sets of independent contact systems, which can control the connection / disconnection of the main power supply and the backup power supply under the action of the controller, so that the transmission and distribution lines can switch between the main power supply and the backup power supply. Therefore, automatic transfer switches are widely used in such situations.

[0003] Existing automatic transfer switches generally provide a switching device between three positions: automatic, manual, and padlock. Operators only need to operate the corresponding mode by manipulating the indicator on the panel. When the indicator shows the "automatic" position, the controller controls the opening and closing of the switch; the operator cannot operate the switch using a handle or other tools, and the padlock plate cannot be pulled out for locking. When the indicator shows the "manual" position, the controller is deactivated, and the operator can operate the switch by inserting a handle or other tools into the operating hole of the operating mechanism. In this case, the padlock plate still cannot be pulled out for locking. When the indicator shows the "padlock" position, the controller is deactivated, and the operator cannot operate the switch using a handle or other tools, but the padlock plate can be pulled out for locking. In some operating scenarios, if a malfunction occurs and maintenance is required, to ensure operator safety, the padlock plate can only be pulled out for locking when both positions are open. However, the existing structure has the following drawbacks: 1) The operation buttons on the panel are small, but the operating force is large, requiring a large operating force; 2) The manual operation handle is usually placed on the side of the switch or separated from the switch, and it is easy to not be able to find the handle during on-site operation or the handle is missing from the factory; 3) The three position states of automatic, manual and padlock are not related to each other, and it is easy to perform the operation of the other state while in one position state, which may lead to safety accidents. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing automatic transfer switch devices by proposing an automatic transfer switch operation mode control component. Through a redesign of the automatic transfer switch device structure, the operating force of the buttons on the panel is reduced. Simultaneously, the linkage mechanism between the automatic, manual, and padlock positions is interconnected, achieving interlocking between the three positions and preventing accidental operation of other positions while in one position. The structure is simple, improving the reliability of position state implementation. Furthermore, after manual operation, the handle must be returned before further operation can be performed, preventing the handle from being lost.

[0005] Technical solution

[0006] To achieve the above technical objectives, this invention proposes an automatic switching mode control component, comprising a face mask, characterized in that: a knob assembly is mounted on the face mask and can rotate to a corresponding operating mode; a cover is mounted on the knob assembly and can rotate synchronously with the knob assembly; a limiting transmission plate is mounted on the knob assembly and can move on the knob assembly; the cover can be linked with the limiting transmission plate; one end of the limiting transmission plate is linked with a micro switch, and the other end is linked with a handle limiting component to lock or unlock the handle; a padlock mechanism is mounted on the face mask and linked with the cover; during the rotation of the knob assembly on the face mask to the corresponding operating mode, the cover can unlock or lock the padlock mechanism.

[0007] Furthermore, the cap is mounted on the guide rod in the knob assembly and is located inside the mask. The limiting transmission plate is mounted on the guide rod in the knob assembly and is located inside the cap, and can move on the guide rod. A transmission protrusion group is provided on the side of the cap facing the limiting transmission plate.

[0008] Furthermore, during the movement of the limiting transmission plate on the guide rod, one end can be linked to a micro switch to be in the corresponding trigger or disconnect state. The padlock mechanism is installed inside the mask and is linked to the transmission protrusion group on the cap. During the rotation of the knob assembly on the mask to the corresponding operating mode, the cap can unlock or lock the padlock mechanism through the transmission protrusion group.

[0009] Furthermore, when in the padlock state, the padlock mechanism can limit and lock the transmission protrusions on the knob to prevent the knob assembly from being accidentally operated to other modes.

[0010] Furthermore, when the handle is in the unlocked state, the mask can be popped out under the action of the push rod mechanism. The push rod mechanism can limit and lock the knob in the corresponding operating mode to prevent the knob assembly from being accidentally operated to other modes.

[0011] Furthermore, the knob assembly includes a knob, which is installed in a knob receiving hole on the outer side of the mask. A guide rod and a limiting buckle are provided on the inner side of the knob. A stop member is provided at the end of the guide rod. A limiting groove is provided on the guide rod corresponding to the limiting buckle. The limiting buckle is installed in the limiting groove so that the limiting cap can rotate synchronously with the knob.

[0012] Furthermore, a limiting protrusion is provided on the side of the cap facing the mask, and a guide rail hole is provided on the mask at the position corresponding to the limiting protrusion. The limiting protrusion is located in the guide rail hole and can limit the rotation stroke and position of the knob.

[0014] Furthermore, during the rotation of the knob assembly on the mask to the corresponding operating mode, the transmission protrusion group and the limiting transmission reaction spring work together to act on the limiting transmission plate, causing the limiting transmission plate to move on the guide rod.

[0015] Furthermore, the transmission protrusion assembly includes a drive stop surface one, a drive stop surface two, a drive stop surface three, and a limiting protrusion disposed on one side of the cap facing the limiting transmission plate. During the rotation of the knob assembly on the mask to the corresponding operating mode, the drive stop surface one, the drive stop surface two, the drive stop surface three, and the limiting transmission reaction spring act on the limiting transmission plate to make it move on the guide rod. During the movement of the limiting transmission plate on the guide rod, the micro switch is linked to make it be in the corresponding triggered or disconnected state. The padlock mechanism is limited and locked by the limiting protrusion or located between the unlocking grooves on the outer edge surface of the cap.

[0016] Furthermore, the limiting transmission reaction spring is mounted on the guide rod, with one end abutting against the stop member and the other end abutting against the limiting surface of the limiting transmission plate.

[0017] Furthermore, the side of the limiting transmission plate that is mounted on the guide rod and linked with the micro switch is located in the limiting groove on the mask, which can ensure that the limiting transmission plate can only move along the axial direction of the guide rod. The side of the limiting transmission plate that is linked with the handle limiting component includes a locking surface and an unlocking surface, and the side of the limiting transmission plate that is linked with the micro switch is a linkage protrusion.

[0018] Furthermore, the padlock mechanism includes a padlock plate, which is installed in a padlock mounting groove on the inner side of the mask and can slide within the padlock mounting groove. The padlock plate is provided with a padlock locking block, which is limited and locked by a limiting protrusion in a corresponding operating mode, or located between the unlocking grooves on the outer edge of the cap so that it can be pulled out from the padlock plate through hole on the mask to realize padlocking. A padlock return spring is connected to the padlock plate to provide a return force after padlocking is completed.

[0019] Furthermore, the padlock plate is connected to a padlock cover, which can pull the padlock plate 9b to slide in the padlock mounting groove and can be pulled out from the through hole of the padlock plate to realize the padlock.

[0020] Furthermore, the top of the padlock plate is provided with a connecting baffle that connects to the connecting slot on the padlock cover, and the padlock plate is provided with a padlock hole for padding.

[0021] Furthermore, the handle limiting component includes a mounting shaft, which is installed in the handle limiting component mounting groove of the face mask. The lower end of the mounting shaft is connected to a linkage surface and a locking block. The linkage surface is in contact with the locking surface and the unlocking surface of the limiting transmission plate. When the linkage surface is in contact with the locking surface and the unlocking surface respectively, the locking block is located in or exits from the connecting groove on the handle, thereby locking or unlocking the handle.

Figure 2Inside the mask 1 shown, the cap 3 and the knob assembly 2 rotate synchronously. A limiting transmission plate 4 is mounted on the guide rod 2a and located inside the cap 3. The limiting transmission plate 4 is connected to a limiting transmission reaction spring 5 to provide a restoring force. A transmission protrusion group 3a is provided on the side of the cap 3 facing the limiting transmission plate 4. One end of the limiting transmission plate 4 is linked to a micro switch 6, and the other end is linked to a handle limiting member 7. During the rotation of the knob assembly 2 on the mask 1 to the corresponding operating mode, it can be activated by the transmission protrusion group 3a and the limiting transmission reaction spring 5. The limiting transmission plate 4 is acted upon, causing it to move on the guide rod 2a. During its movement on the guide rod 2a, one end of the limiting transmission plate 4 can be linked to the micro switch 6 to be in a corresponding triggered or disconnected state, while the other end is linked to the handle limiting component 7 to lock or unlock the handle 8 mounted on the face mask 1. The padlock mechanism 9 is mounted inside the face mask 1 and is linked to the transmission protrusion group 3a. When the knob assembly 2 is rotated on the face mask 1 to a corresponding operating mode, it can unlock or lock the padlock mechanism 9 through the transmission protrusion group 3a. When the padlock mechanism 9 is in the padlock state, it can limit and lock the transmission protrusion group 3a to prevent the knob assembly 2 from being accidentally operated to other modes. When the handle 8 is in the unlocked state, it can pop out of the face mask 1 under the action of the push rod mechanism 10. The push rod mechanism 10 can limit and lock the knob cover 3 in the corresponding operating mode to prevent the knob assembly 2 from being accidentally operated to other modes.

[0050] To better understand the structure and operation of this automatic transfer switch, the following detailed description of each component is provided in conjunction with the accompanying drawings:

[0051] As shown in Figure 3, the knob assembly 2 includes a knob 2b, which is mounted on the attached figure. Figure 2 In the knob receiving hole 1a on the outer side of the mask 1 shown, the knob 2b is provided with a guide rod 2a and a limiting buckle 2c on the inner side of the mask 1. The end of the guide rod 2a is equipped with a stop member 2d. The cover 3 is mounted on the guide rod 2a and has a limiting groove 3b corresponding to the limiting buckle 2c. The limiting buckle 2c is installed in the limiting groove 3b so that the cover 3 can rotate synchronously with the knob 2b. (See attached image) Figure 4b As shown, a limiting protrusion 3c is provided on the side of the screw cap 3 facing the mask 1. A guide rail sliding hole 1c is provided on the mask 1 at a position corresponding to the limiting protrusion 3c. The limiting protrusion 3c, located in the guide rail sliding hole 1c, can limit the rotation stroke and position of the knob 2b. (See attached diagram) Figure 4a and 4bAs shown, the transmission protrusion assembly 3a includes a drive stop surface 3a01, a drive stop surface 3a02, a drive stop surface 3a03, and a limiting protrusion 3a04 disposed on one side of the cap 3 facing the limiting transmission plate 4. During the rotation of the knob assembly 2 on the face mask 1 to the corresponding operating mode, the drive stop surfaces 3a01, 3a02, and 3a03, and the limiting transmission reaction spring 5 act on the limiting transmission plate 4, causing it to move on the guide rod 2a. During the movement of the limiting transmission plate 4 on the guide rod 2a, the micro switch 6 is activated, placing it in a corresponding triggered or deactivated state. The padlock mechanism 9 is either limited and locked by the limiting protrusion 3a04 or located between the unlocking groove 3d on the outer edge of the cap 3. The limiting transmission reaction spring 5 is fitted onto the guide rod 2a, with one end abutting against the stop 2d and the other end abutting against the limiting surface 4a of the limiting transmission plate 4. (See attached diagram) Figure 1b and 5 As shown, the limiting transmission plate 4 is mounted on the guide rod 2a and is linked to the micro switch 6. The side of the limiting transmission plate 4 is located in the limiting groove 1d on the mask 1, which can ensure that the limiting transmission plate 4 can only move along the axial direction of the guide rod 2a. The side of the limiting transmission plate 4 that is linked to the handle limiting member 7 includes a locking surface 4b and an unlocking surface 4c. The side of the limiting transmission plate 4 that is linked to the micro switch 6 is a linkage protrusion 4d.

[0052] As attached Figure 1b and 8 As shown, the padlock mechanism 9 includes a padlock plate 9a, which is installed in the padlock mounting groove 1e inside the face mask 1 and can slide within the padlock mounting groove 1e. A padlock locking block 9a01 is provided on the padlock plate 9a. The padlock locking block 9a01 is limited and locked by a limiting protrusion 3a04 in a corresponding operating mode, or located between the unlocking groove 3d on the outer edge of the cap 3, thus allowing it to be pulled out from the padlock plate through hole 1f on the face mask 1 to achieve padlocking. A padlock return spring 9b is connected to the padlock plate 9a to provide a return force after padlocking is completed. In this embodiment, the padlock return spring 9b is located in the padlock return spring mounting groove 1i on the face mask 1, and the other end is mounted on the padlock return spring mounting post 9a04 on the padlock plate 9a. The padlock plate 9a is connected to the padlock plate as shown in the attached diagram. Figure 10 The padlock pull cover 9c shown is attached. Figure 1a As shown, the padlock cover 9c can pull the padlock plate 9b to slide within the padlock mounting groove 1e and can be pulled out from the padlock plate through hole 1f to realize padlocking. The top of the padlock plate 9a is provided with a connecting baffle 9a02, which is connected to the connecting slot 9c01 on the padlock cover 9c. The padlock plate 9a is provided with a padlock hole 9a03 for padlocking.

[0053] As attached Figure 1b and 7 As shown, the handle limiting component 7 includes a mounting shaft 7a, which is installed in the handle limiting component mounting groove 1g of the face mask 1. The lower end of the mounting shaft 7a is connected to a linkage surface 7b and a locking block 7c. A preload spring 7d is installed on the mounting shaft 7a to provide preload to the linkage surface 7b. The linkage surface 7b is in corresponding contact with the locking surface 4b and the unlocking surface 4c of the limiting transmission plate 4. When the linkage surface 7b is in corresponding contact with the locking surface 4b and the unlocking surface 4c, the locking block 7c is located in or exits from the connecting groove 8a on the handle 8, thereby locking or unlocking the handle 8.

[0054] As attached Figure 1b and 6 As shown, the push rod mechanism 10 includes a push rod shaft 10a, which is installed in the push rod mounting hole 1h inside the mask 1. The cap locking part 10b is provided at one end of the push rod shaft 10a and can be located in the unlocking groove 3d on the outer edge surface of the cap 3 in the corresponding operating mode to lock the cap 3. A push block 10c is provided on the push rod shaft 10a. The push block 10c can push the handle 8 out of the mask 1 under the action of the push spring 10d in the corresponding operating mode.

[0055] In this embodiment, one end of the push spring 10d abuts against the mask 1, and the other end abuts against the push block 10c. The handle 8 is installed in the handle receiving cavity 1b inside the mask 1, as shown in the attached figure. Figure 9 As shown, the upper end of the handle 8 is provided with a connecting groove 8a that is linked with the locking block 7c, the handle 8 is provided with a push rod linkage protrusion 8b that is linked with the push block 10c, and the lower end of the handle 8 is provided with an operating part 8c for operating the switch operating mechanism.

[0056] As shown in Figures 1 and 11, when the knob 2b is rotated to the left of the mask 1 and is in automatic mode, the upper drive stop surface 3a01 of the cover 3 contacts the transmission surface 4e of the limit transmission plate 4, and the limit transmission reaction spring 5 is compressed to the minimum. At this time, the padlock locking block 9a01 on the padlock plate 9a is blocked by the limit protrusion 3a04 on the cover 3 and cannot be pulled up. The linkage protrusion 4d at one end of the limit transmission plate 4 disconnects from the contact piece of the micro switch 6, and the controller receives the signal and enters control. The locking surface 4b at the other end of the limit transmission plate 4 contacts the linkage surface 7b on the handle limit member 7, and the locking block 7c is located in the connecting groove 8a at the upper end of the handle 8, so the handle 8 cannot be pulled out.

[0057] As attached Figure 12As shown, when knob 2b is rotated to the middle position of mask 1 and is in the padlock state, cover 3 rotates clockwise, preferably 75 degrees. Under the action of the spring force of limit transmission spring 5, limit transmission reaction plate 4 moves forward to contact drive stop surface 3a02. Limit transmission reaction spring 5 is still compressed. At this time, unlocking groove 3d of cover 3 moves to the middle position, and the limit of padlock plate 9a is released. At this time, pulling the curved surface on padlock cover 9c can pull out padlock plate 9a. Linkage protrusion 4d at one end of limit transmission plate 4 When the micro switch 6 contacts the contact piece, the controller receives a signal to enter or exit control. The locking surface 4b at the other end of the limit transmission plate 4 contacts the linkage surface 7b on the handle limit member 7. The locking block 7c is located in the connecting groove 8a at the upper end of the handle 8, and the handle 8 cannot be pulled out. At this time, the padlock hole 9a03 set on the padlock plate 9a protrudes from the surface of the mask 1 for padlocking. At this time, the padlock locking block 9a01 set on the padlock plate 9a is located in the unlocking groove 3d of the screw cap 3 for limiting. At this time, the knob 2b cannot be rotated to other modes.

[0058] As attached Figure 13 and 14 As shown, when knob 2b is rotated to the left of mask 1 and is in manual mode, the cover 3 continues to rotate clockwise, preferably 75°. Under the action of the limit transmission spring 5, the limit transmission plate 4 moves forward until it contacts the drive stop surface 3a03. At this time, the limit protrusion 3a04 on the cover 3 rotates to the middle position. At this time, the padlock locking block 9a01 on the padlock plate 9a is blocked by the limit protrusion 3a04 on the cover 3 and cannot be pulled up. The linkage protrusion 4d on the limit transmission plate 4 and the micro switch 6 The contact piece remains in contact, the controller receives a signal to enter or exit control, the unlocking surface 4c at the other end of the limit transmission plate 4 contacts the linkage surface 7b on the handle limit member 7, the handle limit member 7 moves upward, the locking block 7c moves out of the connecting groove 8a of the handle 8, the push rod linkage protrusion 8b of the handle 8 is pushed outward by the pushing block 10c set on the push rod mechanism 10, at this time the handle 8 can be pulled out for manual operation, at this time the cap locking part 10b in the push rod mechanism 10 is located in the unlocking groove 3d, at this time the knob 2b cannot be rotated to other modes.

[0059] This invention provides an automatic transfer switch operation mode control component. By redesigning the structure of the automatic transfer switch device, it achieves interlocking between automatic, padlock, and manual modes through rotation, reducing the operating force of the buttons on the panel. At the same time, the linkage mechanism between the three position states of automatic, manual, and padlock is interconnected, avoiding erroneous operation of other position states while in one position state. The entire control component has a simple structure and improves the reliability of position state realization. In addition, after manual operation, the handle must be returned before operation can be performed again, preventing the handle from being lost.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
