Description

Technical Field

[0001] This invention belongs to the field of low-voltage electrical appliance technology, specifically relating to an automatic transfer switch operation mode control module. 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 module. Through a redesign of the module's structure, the required operating force is reduced. Furthermore, the linkage mechanisms between the automatic, manual, and padlock positions are interconnected, achieving interlocking between these three positions. This prevents erroneous operation of other positions while maintaining a single position. The structure is simple, and the reliability of position state implementation is improved.

[0005] Technical solution

[0006] To achieve the above technical objectives, this invention proposes an automatic switching operation mode control module, comprising a face mask. The module is characterized by: a knob mounted on the face mask capable of rotating to a corresponding operation mode; a drive cam and the knob mounted together, rotating synchronously; a sliding door mounted on the face mask and sliding back and forth within a sliding door mounting slot; a sliding door connected to a sliding door return spring providing a reset force; the drive cam, during rotation, can activate a micro switch to be in a corresponding triggered or disconnected state; the drive cam, during rotation, can activate the sliding door; under the combined action of the drive cam and the sliding door return spring, during its back-and-forth sliding within the sliding door mounting slot, the sliding door can correspondingly close or open the manual operation area and handle mounting slot on the face mask; and under the combined action of the drive cam and the sliding door return spring, during its back-and-forth sliding within the sliding door mounting slot, the sliding door can correspondingly limit or unlock the padlock plate on the face mask.

[0007] The sliding door locking mechanism can limit or unlock the sliding door within the sliding door mounting slot, so that the padlock plate can only be locked when the automatic selector switch is in the double-open position, and when the padlock plate is pulled out, the knob cannot be turned to other operating modes.

[0008] Furthermore, the knob includes a rotating body, which is mounted in a knob mounting slot on the mask. The rotating body has an operating part on the side facing the outside of the mask and a mounting post on the side facing the inside of the mask. The mounting post extends into the inside of the mask from the knob hole at the bottom of the knob mounting slot. The end face of the mounting post is provided with a connecting hole and a connecting limit post for connecting with the drive cam.

[0009] Furthermore, the drive cam includes a drive cam body. One side of the drive cam body, corresponding to the connecting hole and the connecting limit post, is provided with a corresponding drive cam connecting hole and a connecting limit post mounting hole for fixed connection with the knob. A micro switch linkage arm extends from the drive cam body for linkage with the micro switch. An automatic transmission linkage surface, a manual transmission linkage surface, and a padlock linkage surface are provided on the outer edge surface of the drive cam body. As the knob rotates, the drive cam is linked with the sliding door through the automatic transmission linkage surface, the manual transmission linkage surface, and the padlock linkage surface.

[0010] Furthermore, a guide post is provided on one side of the drive cam body facing the inside of the mask, and the guide post is placed in the rotating guide rail on the mask so that its rotation stroke can be restricted.

[0011] Furthermore, the sliding door has a sliding linkage surface corresponding to the automatic transmission linkage surface, the manual transmission linkage surface and the padlock linkage surface, a shielding surface corresponding to the manual operation area, a slot corresponding to the handle mounting hole, and a limiting part corresponding to the padlock plate.

[0012] Furthermore, the sliding door has an opening corresponding to the drive cam body, and the drive cam body rotates within the opening.

[0013] Furthermore, the sliding door is provided with a horizontal sliding limit guide slot, which is installed on the limit guide post inside the mask to ensure that the sliding door slides horizontally.

[0014] Furthermore, the sliding door return spring is horizontally arranged in the vertical direction of the sliding door, and the number of the sliding door return springs is [number] to ensure that the sliding door slides smoothly horizontally.

[0015] Furthermore, one end of the sliding door reset spring is connected to the spring hole on the sliding door, and the other end is installed in the spring mounting hole on the inside of the mask.

[0016] Furthermore, the padlock plate is rotatably mounted on the padlock plate mounting hole inside the mask via a padlock plate mounting shaft. A padlock plate torsion spring is mounted on the padlock plate mounting shaft for the padlock plate to reset. A stop surface is provided on the padlock plate at a position corresponding to the limiting part. During the rotation of the padlock plate, it can be limited or unlocked by the limiting part at the corresponding position.

[0017] Furthermore, the drive cam is located inside the mask.

[0018] Furthermore, the sliding door is mounted on the inside of the mask.

[0019] Furthermore, the mounting cover is installed on the inside of the mask, corresponding to the position of the sliding door. The sliding groove one on the inside of the mounting cover and the sliding groove two on the inside of the mask combine to form a sliding door mounting groove, thereby ensuring that the sliding door does not fall off during the sliding process of the sliding door mounting groove.

[0020] Furthermore, the sliding door locking mechanism includes a lever, which is rotatably mounted inside the mask via a lever shaft. The lever is connected to a lever torsion spring. During rotation, one end of the lever is linked to the sliding door to restrict or release the sliding position of the sliding door within the sliding door mounting groove. The other end of the lever is linked to a cam rocker mechanism.

[0021] Furthermore, the cam rocker mechanism includes a cam and a rocker arm. The cam is mounted on the main shaft of the automatic changeover switch operating mechanism and can be driven by the main shaft to rotate back and forth. The rocker arm is rotatably mounted on the bracket. The cam is provided with a driving surface, and the rocker arm is provided with a linkage surface that corresponds to and contacts the driving surface. During the back and forth rotation of the cam with the main shaft, it can drive the linkage surface through the driving surface to make the rocker arm rotate back and forth around the rotation center. Balance springs are connected to both sides of the rocker arm to keep the rocker arm in force balance when it is driven by the cam to rotate. The upper end of the rocker arm is provided with a lever driving surface one and a lever driving surface two. During the back and forth rotation of the cam with the main shaft, the lever driving surface one and the lever driving surface two are respectively linked to the other end of the lever.

[0022] Furthermore, the driving surface includes a limiting driving surface and an unlocking driving surface. The limiting driving surface is linked with the linkage surface to make the lever driving surface and the other end of the lever work together to restrict the sliding position of the sliding door. The unlocking driving surface is linked with the linkage surface to make the lever driving surface and the other end of the lever work together to unlock the sliding position of the sliding door.

[0023] Beneficial effects

[0024] The present invention provides an automatic transfer switch operation mode control module that can switch between automatic, manual, and padlock positions. Furthermore, compared with existing automatic transfer switch operation mode control components, it has the following advantages:

[0025] 1) The three gears are interlocked and switched by rotation, which is less strenuous;

[0026] 2) The padlock plate can only be pulled out for padlocking when the hook is in the split position;

[0027] 3) The front of the mask has a handle receiving cavity and clear markings, which solves the problems of not being able to find the handle or the handle being missing.

[0028] 4) The entire control module has a simple structure, which improves the reliability of position status realization. Attached Figure Description

[0052] Example

[0053] As attached Figure 1As shown in Figures 2 and 12, an automatic switching operation mode control module includes a face mask 1, a knob 2 mounted on the face mask 1 that can rotate to a corresponding operation mode, a drive cam 3 mounted together with the knob 2, the drive cam 3 and the knob 2 rotating synchronously, and a sliding door 4 mounted in a sliding door mounting groove 1a on the face mask 1 that can slide back and forth. The sliding door 4 is connected to a sliding door return spring 5 to provide a return force. During the rotation of the drive cam 3, it can be linked to a micro switch 6 to be in a corresponding triggered or disconnected state. During the rotation of the drive cam 3, it can also be linked to the sliding door 4. The sliding door 4 is connected to the drive cam 3 and the knob 2. Under the combined action of the sliding door return spring 5, the sliding door 4 can close or open the manual operation area 1b and handle mounting slot 1c on the faceplate 1 during its back-and-forth sliding within the sliding door mounting slot 1a. Under the combined action of the drive cam 3 and the sliding door return spring 5, the sliding door 4 can limit or unlock the padlock plate 7 on the faceplate 1 during its back-and-forth sliding within the sliding door mounting slot 1a. At the same time, the sliding door locking mechanism 8 can limit or unlock the sliding of the sliding door 4 within the sliding door mounting slot 1a, so that the padlock plate 7 can only be padlocked when the automatic selector switch is in the double-open position.

[0054] 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:

[0055] As attached Figure 4 As shown, the knob 2 includes a rotating body 201, which is mounted on the attached... Figure 3 The rotating body 201 has an operating part 201a on the outer side of the mask 1 within the knob mounting slot 101 shown. A mounting post 201b is provided on the inner side of the rotating body 201 facing the mask 1. The mounting post 201b extends from the attached... Figure 3 The knob hole 101a at the bottom of the knob mounting groove 101 extends into the inside of the mask 1. The end face of the mounting column 201b is provided with a connection hole 201b01 and a connection limiting column 201b02 for connecting with the drive cam 3.

[0056] In this embodiment, the drive cam 3 is located inside the mask 1. (See attached image) Figure 5As shown, the drive cam 3 includes a drive cam body 301. A corresponding drive cam connection hole 301a and a connection limit post mounting hole 301b are provided on one side of the drive cam body 301 corresponding to the connection hole 201b01 and the connection limit post 201b02, for fixed connection with the knob 2. A micro switch linkage arm 302 extends from the drive cam body 301 for linkage with the micro switch 6. An automatic transmission linkage surface 301d, a manual transmission linkage surface 301e, and a padlock linkage surface 301f are provided on the outer edge of the drive cam body 301. During the rotation of the knob 2, the drive cam 3 is linked with the sliding door 4 through the automatic transmission linkage surface 301d, the manual transmission linkage surface 301e, and the padlock linkage surface 301f. The drive cam body 301 has a guide post 301g on one side facing the inside of the mask 1. The guide post 301g is placed in the rotating guide rail 102 on the mask 1 and its rotation stroke can be restricted.

[0057] In this embodiment, the sliding door 4 is installed on the inside of the face mask 1. (See attached image) Figure 6 As shown, the sliding door 4 has a sliding linkage surface 401 corresponding to the automatic transmission linkage surface 301d, the manual transmission linkage surface 301e, and the padlock linkage surface 301f. The sliding door 4 has a shielding surface 402 corresponding to the manual operation area 1b. The sliding door 4 has a slot 403 corresponding to the handle mounting slot 1c. The sliding door 4 has a limiting part 404 corresponding to the padlock plate 7. The sliding door 4 has an opening 405 corresponding to the drive cam body 301, and the drive cam body 301 rotates within the opening 405. The sliding door 4 has a horizontal sliding limit guide slot 407, which is mounted on the limiting guide post 104 inside the faceplate 1 to ensure the sliding door 4 slides horizontally. The sliding door return spring 5 is horizontally arranged in the vertical direction of the sliding door 4, and preferably two of them are used to ensure smooth horizontal sliding of the sliding door 4. One end of the sliding door reset spring 5 is connected to the spring hole 406 on the sliding door 4, and the other end is installed in the spring mounting hole 103 on the inner side of the mask 1.

[0058] As attached Figure 7 The padlock plate 7 shown is rotatably mounted on the attached padlock plate mounting shaft 7a. Figure 3At the padlock plate mounting hole 108 on the inner side of the mask 1 shown, a padlock plate torsion spring 7b is mounted on the padlock plate mounting shaft 7a for resetting the padlock plate 7. The padlock plate torsion spring 7b abuts against the torsion spring limiting surface 702 on the padlock plate. A stop surface 701 is provided on the padlock plate 7 at the position corresponding to the limiting part 404. During the rotation of the padlock plate 7, it can be limited or unlocked by the limiting part 404 at the corresponding position. The padlock plate 7 is provided with several padlock holes 703 of different diameters to adapt to locks of different sizes.

[0059] As attached Figure 9 The mounting cover 9 shown is installed inside the mask 1 and corresponds to the position of the sliding door 4. The sliding groove 901 on the inner side of the mounting cover 9 and the sliding groove 105 on the inner side of the mask 1 combine to form the sliding door mounting groove 1a, thereby ensuring that the sliding door 4 does not fall off during the sliding process of the sliding door mounting groove 1a.

[0060] The sliding door locking mechanism 8 includes, as shown in the appendix Figure 8 The lever 8a shown is rotatably mounted inside the mask 1 via a lever shaft 8b and its rotation stroke is limited by a lever limiting protrusion 110 on the mask 1, as illustrated in the attached diagram. Figure 2 As shown, the lever 8a is connected to a lever torsion spring 8c. The lever torsion spring 8c is mounted on the lever shaft 8b and abuts against the lever limiter 8a03 on the lever 8a. During the rotation of the lever 8a, one end is linked with the sliding door 4 to restrict or release the sliding position of the sliding door 4 in the sliding door mounting groove 1a. The other end of the lever 8a is linked with the cam rocker mechanism 10.

[0061] Specifically, it means: as attached Figure 11 and 13 As shown, the cam rocker mechanism 10 includes a cam 10a and a rocker arm 10b. The cam 10a is mounted on the main shaft 11 of the automatic changeover switch operating mechanism via a connecting square hole 10a02 and can be driven by the main shaft 11 to rotate back and forth. The rocker arm 10b is rotatably mounted on the bracket 12, as shown in the attached figure. Figure 11As shown, the cam 10a is provided with a driving surface 10a01, and the rocker arm 10b is provided with a linkage surface 10b01 that is in corresponding contact with the driving surface 10a01. During the back-and-forth rotation of the main shaft 11, the cam 10a can drive the linkage surface 10b01 through the driving surface 10a01 to make the rocker arm 10b rotate back and forth around the rotation center o. Balance springs 10c are connected to both sides of the rocker arm 10b to keep the rocker arm 10b in force balance when it is driven to rotate by the cam 10a. One end of the balance spring 10c is mounted on the bracket 12, and the other end is mounted on the balance spring mounting hole 10b04 on the rocker arm 10b. The upper end of the rocker arm 10b is provided with a lever driving surface 10b02 and a lever driving surface 10b03. During the back-and-forth rotation of the cam 10a with the main shaft 11, the lever driving surface 10b02 and the lever driving surface 10b03 are respectively linked to the other end of the lever.

[0062] To elaborate further, see the attached document. Figure 16 As shown, the driving surface 10a01 includes a limiting driving surface 10a0101 and an unlocking driving surface 10a0102. The limiting driving surface 10a0101 is linked with the linkage surface 10b01 to make the lever driving surface 10b02 linked with the other end of the lever 8a to restrict the sliding position of the sliding door 4. The unlocking driving surface 10a0102 is linked with the linkage surface 10b01 to make the lever driving surface 10b03 linked with the other end of the lever 8a to unlock the sliding position of the sliding door 4.

[0063] The working principle of this embodiment is as follows: (see attached) Figure 1As shown in Figures 2 and 3, the micro switch 6 is installed in the micro switch mounting slot 109 inside the face mask 1. The knob 2 is installed in the knob mounting slot 101 from the front of the face mask 1, and the drive cam 3 is installed from the back of the face mask 1. The connecting limit post 201b02 cooperates with the connecting limit post mounting hole 301b, and the guide post 301g is placed in the rotating guide rail 102 on the face mask 1. The drive cam 3 is fixed to the knob 2 by fasteners installed in the connecting hole 201b01 and the drive cam connecting hole 301a. The lever 8a and lever torsion spring 8c, as well as the padlock plate 7 and padlock plate torsion spring 7b, are respectively installed in the lever mounting hole 106 and the padlock plate mounting hole 106 on the face mask 1. In section 08, a sliding door reset spring 5 is installed in the spring hole 406 of the sliding door 4. The sliding limit guide slot 407 cooperates with the limit guide post 104 on the inner side of the mask 1. The other end of the sliding door reset spring 5 is hung in the spring mounting hole 103 on the inner side of the mask 1. The mounting cover 9 is installed on the top of the sliding door 4. The mounting cover limit hole 9a cooperates with the limit guide post 104. The mounting cover mounting post 107 on the mask 1 cooperates with the mounting cover connecting hole 9b. The installation is fixed by fasteners to ensure that the sliding door 4 will not fall off during the sliding process of the sliding door mounting slot 1a.

[0064] As attached Figure 1 and 17 As shown, when knob 2 is rotated until the operating part 201a on knob 2 faces upward and is in the automatic position, the micro switch linkage arm 302 on drive cam 3 contacts the paddle on micro switch 6, micro switch 6 is turned on, and an automatic control signal is sent to the controller, and the controller enters the control state. At this time, the sliding door 4 moves towards the end closer to the padlock plate 7 under the pulling force of the sliding door return spring 5 until the corresponding part of the sliding linkage surface 401 contacts the automatic gear linkage surface 301d on drive cam body 301. The manual operation area 1b on the faceplate 1 is closed by the shielding surface 402 on the sliding door 4, and the slot 403 is located at the position shown in the attached diagram. Figure 10 The handle 13 is in the handle limiting groove 1301 shown. The handle 13 cannot be pulled out, so manual operation is not possible. The limiting part 404 set on the sliding door 4 is located above the stop surface 701 set on the padlock plate 7, so the padlock plate 7 cannot be rotated out for padlocking.

[0065] As attached Figure 1 and 18As shown, when the knob 2 is rotated 90° counterclockwise until the operating part 201a on the knob 2 is in the manual position to the left, the manual shift linkage surface 301e on the drive cam 3 also rotates 90°, the micro switch 6 is disconnected, the controller exits control, and the manual shift linkage surface 301e on the drive cam 3 contacts the sliding linkage surface 401 on the sliding door 4, causing the sliding door 4 to move away from the padlock plate 7. The limit of the manual operation area 1b is released, and the limit of the handle 13 is also released. At this time, the handle 13 can be pulled out to perform manual opening and closing operations. The limit part 404 on the sliding door 4 is still located above the stop surface 701 on the padlock plate 7, and the padlock plate 7 cannot be pulled out for padlocking.

[0066] As attached Figure 1 and 19 As shown, when the knob 2 is rotated 180° counterclockwise until the operating part 201a on the knob 2 faces downward, the padlock linkage surface 301f on the drive cam 3 also rotates 180° until the sliding linkage surface 401 contacts the padlock linkage surface 301f. At this time, the micro switch 6 is still disconnected, the controller is out of control, and the sliding door 4 moves towards the end of the padlock plate 7 under the pulling force of the sliding door return spring 5. The manual operation area 1b on the mask 1 is closed by the shielding surface 402 on the sliding door 4, and the slot 403 is located in the handle limiting groove 1201 on the handle 13, so manual operation is not possible. The limiting part 404 on the sliding door 4 moves to the left side of the stop surface 701 on the padlock plate 7, and the limiting of the padlock plate 7 is released. At this time, the padlock plate 7 can be pulled out and rotated until the padlock hole 701 on the padlock plate 7 is exposed on the front of the mask, and the padlock can be engaged.

[0067] As attached Figure 11 and 12 As shown, when the operating mechanism is rotated to the power-on position and displayed in the power display window 111 on the mask, the cam 10a rotates to the power-on position with the main shaft 11 of the mechanism. The limit drive surface 10a0101 on the cam 10a contacts the linkage surface 10b01 on the rocker arm 10b. The rocker arm 10b rotates under the action of the balance spring 10c. The lever drive surface 10b02 on the rocker arm 10b contacts the other end 8a01 of the lever 8a, causing the lever 8a to rotate under the action of the lever torsion spring 8c. The sliding door 4 is unable to slide away from the padlock plate 7 due to the action of the lever 8a02. Therefore, the knob 2 cannot be rotated to the padlock position at this time.

[0068] As attached Figure 13 and 14As shown, when the operating mechanism rotates to the double-split position, the cam 10a rotates to the double-split position along with the main shaft 11 of the mechanism. The unlocking drive surface 10a0102 on the cam 10a contacts the linkage surface 10b01 on the rocker arm 10b. The rocker arm 10b is stopped in the middle position by the action of the balance spring 10c. The unlocking drive surface 10a0102 on the rocker arm 10b contacts the other end 8a01 of the lever 8a, causing the lever 8a to rotate. One end 8a02 of the lever 8a moves away from the surface. Cover 1, the limit of sliding door 4 is released. At this time, if the knob 2 is operated to the padlock position, due to the action of the step part 401a on the sliding linkage surface 401 on the sliding door 4, the sliding door 4 will first slide a distance away from the padlock plate 7 under the action of the drive cam 3, and then move closer to the padlock plate 7 under the action of the sliding door return spring 5 until the corresponding part of the sliding linkage surface 401 on the sliding door 4 contacts the drive cam 301f. Only then can the padlock plate 7 be pulled out for padlocking.

[0069] This invention provides an automatic transfer switch operation mode control module. By redesigning the structure of the automatic transfer switch operation mode control module, interlocking between automatic, padlock, and manual modes is achieved through rotation, reducing the operating force required for the automatic transfer switch operation mode control module. At the same time, the linkage mechanisms between the three position states of automatic, manual, and padlock are interconnected, avoiding erroneous operation of other position states while in one position state. The entire control module has a simple structure and improves the reliability of position state realization.
