[0002] As a switching device in the electrical field, high-voltage circuit breakers are used to cut off or connect the no-load current and load current in the high-voltage circuit under normal circumstances; in addition, when a power system fault occurs, the high-voltage circuit breaker is used to disconnect the faulty part of the circuit to prevent the accident from expanding.

[0003] The main working states of the electric operating mechanism of the high-voltage circuit breaker include closing and opening. When the closing coil of the operating mechanism is energized, the closing iron core is attracted, and the movable conductive rod of the vacuum interrupter is moved through the crank arm and the connecting rod to close the circuit breaker; when the opening coil of the operating mechanism is energized, the opening iron core is attracted, the lock is released, and the circuit is quickly disconnected under the action of the opening spring. To avoid misoperation, the structure related to the manual energy release function will be locked when manual energy release is not performed.

[0004] A Chinese patent with announcement number CN220208873U discloses a locking plate mechanism for an energy storage type electric operator, which includes an energy release button and a manual-automatic switch key installed on the electric operator body, and the manual-automatic switch key is movably configured on the electric operator body; it also includes a zipper slider movably configured on the electric operator body, and the manual-automatic switch key can drive the zipper slider to move from a first position to a second position; the second position is located below the energy release button, and the zipper slider located at the second position can lock the energy release button.

[0005] The locking plate mechanism has many installation parts, and the parts used to install the locking plate mechanism are all small parts, which are easy to be missed during the installation process, thereby increasing the difficulty of installing the locking plate mechanism. Utility Model Content

[0006] In order to simplify the installation steps of the locking plate device, the present application provides a locking plate device of an electric control mechanism.

[0007] The locking plate device of the electric control mechanism provided in the present application adopts the following technical solution:

[0008] A locking plate device of an electric control mechanism comprises a base plate and a locking plate slidably matched with the base plate, the base plate being provided with a mounting hole for realizing a bolt connection with an electric control body, and three gears are arranged between the base plate and the lock plate along the relative sliding direction corresponding to the three states of regulating the electric control, and a locking piece is also arranged between the base plate and the lock plate corresponding to the three gears, a guide groove is opened on the lock plate along the upper surface perpendicular to its own sliding direction, and a guide assembly for realizing relative sliding between the base plate and the lock plate is arranged between the base plate and the lock plate, the guide assembly comprises a guide rod slidably arranged in the guide groove and a limit block arranged at the end of the guide rod, and the end of the guide rod away from the limit block is arranged on the base plate, and when the lock plate slides between the base plate and the base plate, the limit block is arranged to contact the wall surface of the lock plate.

[0009] By adopting the above technical solution, the sliding cooperation between the guide rod and the guide groove allows the lock plate to slide between the bottom plate under the simultaneous limit of the limit block, and the state of the lock plate is locked by the locking member, thereby realizing the three states of regulating the electric operation. The lock plate device has a simple structure and can lock the electric operation state without adding too many additional parts.

[0010] Optionally, a through slot is provided on the base plate, and the locking member includes an elastic locking rod arranged on the inner side wall of the through slot and a plug-in block arranged at the end of the locking rod away from the connection, the plug-in block is arranged on the side of the locking rod facing the lock plate, and a plug-in slot is provided on the side of the lock plate facing the base plate corresponding to the plug-in block, the plug-in block is plugged into the plug-in slot, three plug-in slots are arranged at equal intervals along the sliding direction of the lock plate, and the three plug-in slots correspond to the three gears of the electric operation respectively.

[0011] By adopting the above technical solution, the plug-in cooperation between the plug-in block and the plug-in slot causes a jam every time the lock plate slides to the plug-in block and is plugged into a plug-in slot. Moreover, since the locking rod has the property of elastic recovery, a hitting sound is made every time the plug-in block is plugged into a plug-in slot, which makes it convenient for the operator to use the lock plate device to adjust the state of the electric operation.

[0012] Optionally, the plug-in block is arranged in a hemispherical shape, and the plug-in slot is arranged with a hemispherical groove shape corresponding to the shape of the plug-in block.

[0013] By adopting the above technical solution, the plug-in block is set in a hemispherical shape and is plugged into and matched with the hemispherical plug-in groove, so that when the staff slides the lock plate for electric shifting, the friction between the plug-in block and the lock plate wall during the sliding process is reduced.

[0014] Optionally, a shift block is provided on the side of the lock plate facing away from the base plate to facilitate the operator to adjust the gear position.

[0015] By adopting the above technical solution, the operator can quickly shift the electric control connected to the locking plate device through the wave shift block.

[0016] Optionally, when the locking plate is located directly above the bottom plate, a clearance opening for the limiting block to extend into is opened on the locking plate directly above the corresponding limiting block, and the clearance opening is connected to the guide groove.

[0017] By adopting the above technical solution, the installation and disassembly between the lock plate and the base plate are facilitated.

[0018] Optionally, an auxiliary limit groove parallel to the guide groove is opened on the lock plate, and an auxiliary limit assembly is also provided on the base plate to prevent the base plate and the lock plate from offsetting during the sliding process along the arrangement direction of the three plug-in grooves.

[0019] By adopting the above technical solution, the position of the lock plate or the sliding stroke can be further restricted to avoid the lock plate from shifting during movement, thereby reducing the impact of the lock plate on the electrical control state regulation.

[0020] Optionally, a connecting portion is provided on the side wall of the lock plate along its own sliding direction for the operator to install different types of electric operating tongues. The connecting portion includes two limit plates arranged on the lock plate parallel to the sliding direction of the lock plate, and the opposite sides of the two limit plates are provided with clamping grooves for clamping different types of electric operating tongues.

[0021] By adopting the above technical solution, according to different models of electric operators, the pressing tongues can be replaced and installed in the clamping grooves for manual energy release buttons at different positions, thereby improving the application range of the lock plate.

[0022] Optionally, the plug-in block is a ball, and a ball seat is provided on the locking rod corresponding to the ball, and the ball is limited in the ball seat and rotates with the ball seat.

[0023] By adopting the above technical solution, the ball rotates and cooperates in the ball seat, so that during the sliding process of the lock plate, the friction force of the plug-in block sliding from one plug-in slot to an adjacent plug-in slot is further reduced, making it easier for the operator to shift gears.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The sliding cooperation between the guide rod and the guide groove enables the lock plate to slide between the bottom plate under the simultaneous limit of the limit block, and the lock plate is locked by the lock piece, thereby realizing the three states of regulating the electric operation. The lock plate device has a simple structure and can lock the electric operation state without adding too many additional parts;

[0026] 2. The plug-in cooperation between the plug-in block and the plug-in slot makes the lock plate jam each time it slides to the plug-in block and plugs into a plug-in slot. And because the locking rod has the property of elastic recovery, the plug-in block makes a hitting sound each time it is plugged into a plug-in slot, which is convenient for the operator to use the lock plate device to adjust the state of the electric operation;

[0027] 3. The plug-in block is hemispherical and plugged into the hemispherical plug-in slot, so that when the staff slides the lock plate for electric shifting, the friction between the plug-in block and the wall of the lock plate is reduced during the sliding process.

[0035] The following is combined with Figure 1-5 This application is described in further detail.

[0036] The embodiment of the present application discloses a locking plate device of an electric control mechanism.

[0037] Example 1

[0038] Reference Figure 1 , Figure 2 and Figure 3 A locking plate device of an electric control mechanism includes a base plate 1 and a locking plate 2, a mounting hole 11 is opened on the base plate 1, a relatively sliding guide component 3 is arranged between the base plate 1 and the locking plate 2, and three gears are arranged between the base plate 1 and the locking plate 2 along the relative sliding direction corresponding to the three states of regulating electric control, and a locking member 4 is arranged between the base plate 1 and the locking plate 2 corresponding to the three gears.

[0039] Reference Figure 2 Specifically, the three gears correspond to the electric energy storage state, manual energy release state and manual energy storage state of the electric operation. When the lock plate 2 is closest to the bottom plate 1, it corresponds to the electric energy storage state, and then moves away from the bottom plate 1 to the manual energy release state and manual energy storage state. In the electric energy storage state, you cannot store energy manually or release energy manually; in the manual energy release state, you can release energy manually but not store energy manually; in the manual energy storage state, you cannot release energy manually but can store energy manually.

[0040] Reference Figure 1 , Figure 2 and Figure 3 The lock plate 2 is made to slide on the base plate 1 through the guide assembly 3, thereby realizing the sliding fit between the lock plate 2 and the base plate 1, and the state of the lock plate 2 is locked through the locking member 4, thereby realizing the three states of regulating the electric operation.

[0041] Reference Figure 1 The lock plate 2 has a guide groove 21 opened on it perpendicular to its sliding direction. When the lock plate 2 is located directly above the bottom plate 1, a clearance opening 22 for the limit block 32 to extend into is opened on the lock plate 2 directly above the corresponding limit block 32, and the clearance opening 22 is connected to the guide groove 21.

[0042] Reference Figure 1 and Figure 2 The guide assembly 3 includes a guide rod 31 and a stop block 32. The guide rod 31 is slidably disposed in the guide groove 21, and one end of the guide rod 31 close to the bottom plate 1 is integrally formed on the bottom plate 1, while the stop block 32 is integrally formed on the end of the guide rod 31 away from the bottom plate 1. When the lock plate 2 slides between the bottom plate 1, the stop block 32 is disposed in contact with the wall surface of the lock plate 2.

[0043] Reference Figure 2 and Figure 3The locking member 4 includes a locking rod 41 and a plug-in block 42, and a through slot 43 is provided on the bottom plate 1. The locking rod 41 in this embodiment is made of elastic plastic material, and the locking rod 41 is integrally formed on the side wall of the through slot 43 perpendicular to the gear distribution direction. The plug-in block 42 is located on the side of the locking rod 41 facing the lock plate 2, and is integrally formed at the end of the locking rod 41 away from the connection. The plug-in block 42 of this embodiment is hemispherically arranged, and a hemispherical plug-in groove 23 for plugging in is provided on the side of the lock plate 2 facing the bottom plate 1 corresponding to the hemispherical plug-in block 42, and three plug-in grooves 23 are evenly spaced along the sliding direction of the lock plate 2, and the three plug-in grooves 23 correspond to the three gears of the electric operation.

[0044] Reference Figure 1 In order to further limit the sliding fit between the lock plate 2 and the base plate 1, an auxiliary limit groove 24 parallel to the guide groove 21 is opened on the lock plate 2, and an auxiliary limit assembly 5 is also provided on the base plate 1. The auxiliary limit assembly 5 is used to prevent the base plate 1 and the lock plate 2 from deviating during the sliding process along the arrangement direction of the three plug-in grooves 23.

[0045] Reference Figure 1 The auxiliary limiting assembly 5 includes an auxiliary limiting rod 51 and a stopper 52. The auxiliary limiting rod 51 is slidably disposed in the auxiliary limiting groove 24, and one end of the auxiliary limiting rod 51 close to the bottom plate 1 is integrally formed on the bottom plate 1, while the stopper 52 is integrally formed at the end of the auxiliary limiting rod 51 extending out of the auxiliary limiting groove 24. When the lock plate 2 slides between the bottom plate 1, the stopper 52 is disposed in abutment with the wall surface of the lock plate 2.

[0046] Reference Figure 1 In order to facilitate the adaptation of different types of electric operators, a connecting portion 6 is provided on the side wall of the lock plate 2 along its own sliding direction. The connecting portion 6 in this embodiment includes two limit plates 61. The opposite sides of the two limit plates 61 are provided with a snap-in groove 611. The two snap-in grooves 611 are used to snap-in different types of electric operator pressure tongues.

[0047] Reference Figure 1 In order to facilitate the operator to adjust the gear position of the lock plate 2, a shift block 7 is integrally formed on the side of the lock plate 2 facing away from the bottom plate 1.

[0048] The implementation principle of the locking plate device of an electric control mechanism in the embodiment of the present application is: the sliding cooperation between the guide rod 31 and the guide groove 21 allows the locking plate 2 to slide between the bottom plate 1 under the simultaneous limitation of the limiting block 32.

[0049] Through the plug-in cooperation between the plug-in block 42 and the plug-in slot 23, the lock plate 2 will be stuck every time it slides to the plug-in block 42 and is plugged into a plug-in slot 23. Since the locking rod 41 has the property of elastic recovery, a knocking sound will be made every time the plug-in block 42 is plugged into a plug-in slot 23. When the operator slides the dial block 7 to realize the sliding and gear adjustment of the lock plate 2, the three states of the electric control can be realized.

[0050] Example 2

[0051] Reference Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that the plug-in block 42 in this embodiment is a ball, a ball seat 8 is integrally formed on the locking rod 41, the ball is limited in the ball seat 8, and rotates with the ball seat 8.

[0052] The implementation principle of Example 2 is that the ball rotates and cooperates in the ball seat 8, so that during the sliding process of the lock plate 2, the friction force of the plug-in block 42 sliding from one plug-in slot 23 to the adjacent plug-in slot 23 is further reduced, making it easier for the operator to shift gears.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
