Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of power distribution equipment, and in particular to a drive mechanism, a rotary switch, and a power distribution system. Background Art

[0002] With the development of power distribution systems, the requirements for rotary switches used in these systems are increasing. For example, in the event of a circuit fault, rotary switches are required not only to generate an alarm but also to quickly disconnect the circuit to protect it. To meet these requirements, conventional rotary switches are designed to store energy, releasing it to disconnect the system when a fault occurs.

[0003] However, based on the structure of the existing rotary switch, it may happen that the rotary switch is closed but no energy is stored, resulting in the rotary switch being unable to automatically disconnect the power distribution system when a fault occurs in the power distribution system. Summary of the Invention

[0004] In view of this, the embodiments of the present application provide a drive mechanism, a rotary switch and a power distribution system, which enable the rotary switch to store energy first and then close the switch, thereby enabling the rotary switch to disconnect the power distribution system when a fault occurs in the power distribution system.

[0005] In a first aspect, an embodiment of the present application provides a driving mechanism. The driving mechanism is applied to a rotary switch. The driving mechanism includes a rotating shaft module, a lock, an operating member, a first elastic member, and a second elastic member. The lock is connected to the rotating shaft module. The operating member is installed on the rotating shaft module. The first elastic member abuts the operating member and the rotating shaft module. The second elastic member abuts the operating member and the rotating shaft module. The elastic potential energy of the first elastic member is greater than the elastic potential energy of the second elastic member. During the first period, the rotary switch is opened, and the first elastic member rotates in the first direction with the operating member to be locked by the lock. During the second period, the second elastic member rotates in the second direction with the operating member, and drives the rotating shaft module to rotate, closing the rotary switch. The first period is earlier than the second period, and the first direction is opposite to the second direction.

[0006] Considering the technical problem that rotary switches in the prior art may not store energy before closing, the drive mechanism of the embodiment of the present application sets the rotation direction of the first elastic member when the operating member controls energy storage to be opposite to the rotation direction when controlling the rotary switch to close, and sets the elastic potential energy of the first elastic member to be greater than the elastic potential energy of the second elastic member. This allows the first elastic member to apply a force to the shaft module in the first direction to prevent the shaft module from being driven by the second elastic member to rotate in the second direction during the process of closing the rotary switch before the first elastic member completes energy storage. In addition, when the rotary switch is closed after the first elastic member completes energy storage, the first elastic member will not prevent the shaft module from being driven by the second elastic member to rotate in the second direction, allowing the rotary switch to close smoothly. In other words, the drive mechanism of the embodiment of the present application enables the rotary switch to store energy first and then close.

[0007] In one possible design, the operating member includes an operating shaft, a lever, and a latch. The operating shaft is mounted on the shaft module. The lever is connected to the operating shaft. The latch is located in the lever's rotational path, and is pushed by the lever to engage with the latch. The first end of the first elastic member abuts the latch. During the second period, the first end of the second elastic member abuts the lever.

[0008] Through the above scheme, during the first period, the operating shaft is forced to rotate in the first direction, and the lever rotates in the first direction along with the operating shaft. When the lever rotates in the first direction, it pushes the jump buckle, causing the jump buckle to rotate in the first direction and engage with the lock buckle. In the process of the lever pushing the jump buckle, the second end of the first elastic member is fixed by the rotating shaft module, and the jump buckle pushes the first end of the first elastic member, causing the first elastic member to be compressed and store energy. During the second period, the operating shaft is forced to rotate in the second direction, and the lever rotates in the second direction along with the operating shaft. When the lever rotates in the second direction, it pushes the first end of the second elastic member, and the second end of the second elastic member pushes the rotating shaft module, causing the rotating shaft module to rotate in the second direction, thereby closing the rotary switch.

[0009] In one possible design, the jump buckle includes a locking arm and a push arm connected to each other; the locking arm is located on the rotation path of the lever so as to be locked with the lock buckle by the push of the lever; the first end of the first elastic member abuts the push arm.

[0010] According to the above solution, during the first period, when the lever pushes the locking arm, the pushing arm pushes the first end of the first elastic member, causing the first elastic member to be compressed and store energy.

[0011] In one possible design, the jump buckle includes a connected locking arm and a main disk; the main disk is located on the rotation path of the lever, so that it is pushed by the lever to lock the locking arm with the lock buckle; the first end of the first elastic member abuts the main disk.

[0012] According to the above solution, during the first period, when the lever pushes the main disk, the main disk pushes the first end of the first elastic member, causing the first elastic member to be compressed and store energy.

[0013] In one possible design, the jump buckle includes a locking arm, a push arm and a main disk, and the locking arm and the push arm are both connected to the main disk; the main disk is located on the rotation path of the lever to be pushed by the lever to lock the locking arm with the lock buckle; the first end of the first elastic member abuts the push arm.

[0014] According to the above solution, during the first period, when the lever pushes the main disk, the pushing arm pushes the first end of the first elastic member, causing the first elastic member to be compressed and store energy.

[0015] In a possible design, the hinge module includes an inner cavity, the first elastic member and the second elastic member are both located in the inner cavity, and the first elastic member and the second elastic member both abut against a cavity wall of the inner cavity.

[0016] With this solution, during the first period, the second end of the first elastic member is fixed by the inner cavity wall, and the first end of the first elastic member is pushed by the operating member to rotate in the first direction, thereby locking the first elastic member and storing energy. During the second period, the first end of the second elastic member is pushed by the operating member to rotate in the second direction, and the second end of the second elastic member pushes against the inner cavity wall, causing the hinge module to rotate in the second direction, closing the rotary switch.

[0017] In one possible design, the hinge module includes an inner cavity, the first elastic member is located outside the hinge module and abuts against the outer wall of the hinge module; the second elastic member is located in the inner cavity and abuts against the cavity wall of the inner cavity.

[0018] This design is different from the previous design in that, during the first period, the second end of the first elastic member can be fixed by the outer wall of the hinge module, and the first end of the first elastic member can be pushed by the operating member and rotated in the first direction, so that the first elastic member is locked by the lock.

[0019] In one possible design, when the first elastic member is located within the inner cavity, a gap is defined in the inner cavity wall, and the second end of the first elastic member is embedded in the gap. Alternatively, when the first elastic member is located outside the hinge module, a gap is defined in the outer wall of the hinge module, and the second end of the first elastic member is embedded in the gap.

[0020] Through the above solution, during the first period, the second end of the first elastic member can be pushed and fixed by the inner wall of the gap, and the first end of the first elastic member can be pushed and rotated in the first direction by the operating member, so that the first elastic member is locked by the lock.

[0021] In a possible design, a cavity wall of the inner cavity is provided with a boss, and during the second period, the second end of the second elastic member abuts against the boss.

[0022] Through the above solution, during the second period, the second end of the second elastic member can drive the rotating shaft module to rotate in the second direction by pushing the boss, thereby closing the rotary switch.

[0023] In one possible design, the hinge module includes a first hinge and a second hinge, which overlap to form an inner cavity; the second end of the first elastic member abuts the second hinge; during the second period, the second end of the second elastic member abuts the first hinge.

[0024] With this solution, during the first period, the second end of the first elastic member can be fixed by the second rotating shaft, allowing the first end of the first elastic member to be driven by the operating member to compress and store energy. During the second period, the second end of the second elastic member can push against the first rotating shaft, causing the rotating shaft module to rotate in the second direction, closing the rotary switch.

[0025] In a second aspect, embodiments of the present application further provide a rotary switch comprising a contact mechanism, a trip mechanism, and the drive mechanism of the first aspect; the contact mechanism is connected to the shaft module; and the trip mechanism is capable of pushing against a lock to cause the lock to unlock the first elastic member.

[0026] With this solution, the shaft module can drive the contact mechanism to connect or disconnect when it rotates, closing the rotary switch when the contact mechanism is connected and opening the rotary switch when the contact mechanism is disconnected. The trip mechanism can push against the lock catch, causing the lock catch to release the lock on the first elastic member, allowing the first elastic member to release energy and drive the shaft module to rotate, causing the shaft module to drive the contact mechanism to disconnect, thereby opening the rotary switch.

[0027] In one possible design, the driving mechanism also includes a reset pressure rod, which is installed on the operating part; during the third time period, the reset pressure rod rotates in the first direction with the operating part to reset the tripping mechanism; wherein the third time period is located within the first time period, and the end time of the third time period is earlier than the end time of the first time period.

[0028] Through the above solution, during the rotation of the operating member in the first direction, the trip mechanism can be reset first, and then the first elastic member can store energy, allowing the trip mechanism to be fully reset. If the trip mechanism is fully reset, at the moment the rotary switch is closed, the trip mechanism will not push against the lock catch due to not being reset, causing the first elastic member to be unlocked by the lock catch and disconnect the rotary switch, which facilitates the smooth closing of the rotary switch. Furthermore, after the rotary switch is successfully closed, in the event of a power distribution system failure, the trip mechanism can push against the lock catch in the first direction, causing the lock catch to release its lock on the first elastic member, facilitating the first elastic member to release energy and open the rotary switch.

[0029] In a third aspect, embodiments of the present application further provide a power distribution system. The power distribution system includes a current detection device, a controller, and the rotary switch of the second aspect, wherein the current detection device, the controller, and the rotary switch are electrically connected in sequence. The current detection device is configured to detect a predetermined fault in the power distribution system and transmit the predetermined fault to the controller. The controller is configured to receive the predetermined fault, generate a trip signal based on the predetermined fault, and transmit the trip signal to the rotary switch to trip the rotary switch.

[0030] On the premise that the aforementioned rotary switch can be tripped when a fault occurs in the power distribution system, the power distribution system can be protected by the rotary switch.

[0031] In a possible design, the preset fault includes at least one of string reverse connection, current backflow, and bus short circuit.

[0051] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0053] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase "embodiment" in various places in the specification does not necessarily refer to the same embodiment, nor does it necessarily refer to independent or alternative embodiments that are mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0054] The directional terms appearing in the following description refer to the directions shown in the drawings and are not intended to limit the specific structure of this application. For example, in the description of this application, the terms "upper," "lower," "inner," "outer," "clockwise," "counterclockwise," and so on, indicating directions or positional relationships, are based on the directions or positional relationships shown in the drawings and are intended only to facilitate the description of this application and simplify the description. They do not indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be understood as limitations on this application.

[0055] Furthermore, expressions indicating directions such as the X direction and the Y direction used to illustrate the operation and construction of the components of this embodiment are not absolute but relative, and although these indications are appropriate when the components are in the positions shown in the drawings, when these positions are changed, these directions should be interpreted differently to correspond to the changes.

[0056] In addition, the terms "first", "second", etc. in the description and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order, and may explicitly or implicitly include one or more such features.

[0057] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, the "connection" or "connection" of a mechanical structure may refer to a physical connection. For example, the physical connection may be a fixed connection, such as a fixed connection through a fixing member, such as a fixed connection through a screw, bolt, or other fixing member; the physical connection may also be a detachable connection, such as a mutual snap connection or snap connection; the physical connection may also be an integral connection, such as a connection formed by welding, bonding, or integral molding. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0058] Rotary switches are commonly used in power distribution systems to control their on / off operation. Specifically, a rotary switch comprises a drive mechanism, a contact mechanism, and a trip mechanism. Under normal circumstances, the drive mechanism is responsible for applying force and controlling the opening and closing of the contact mechanism. When the contact mechanism is closed, the rotary switch closes, connecting the power distribution system. When the contact mechanism is open, the rotary switch opens, disconnecting the power distribution system. In the event of a power distribution system fault, the trip mechanism controls the drive mechanism, causing it to disconnect the contact mechanism, thereby automatically opening the rotary switch and disconnecting the power distribution system.

[0059] In the prior art, the drive mechanism includes an operating member, an energy storage component, and a drive member. When the drive mechanism is subjected to force and controls the opening or closing of the rotary switch, it is mainly based on the rotation of the operating member and the drive member. Specifically, the operating member controls the rotation of the drive member, and when the drive member rotates, the rotary switch is opened or closed. When the drive mechanism is controlled by the tripping mechanism to open the rotary switch, it is mainly based on the operating member, the energy storage component, and the drive member. Specifically, under normal circumstances, the operating member controls the energy storage component to store energy; in the event of a power distribution system failure, the energy storage component releases energy and drives the drive member to rotate, causing the rotary switch to automatically open.

[0060] In addition, in the prior art, see Figure 1 The operating member rotates in the same direction when controlling the energy storage component to store energy as when controlling the rotary switch to close. Furthermore, the operating member controls the energy storage component to store energy after controlling the rotary switch to close. This can cause the rotary switch to close but the energy storage component to not store energy. If the energy storage component does not store energy, the trip mechanism cannot release energy when controlling the drive mechanism, preventing the rotary switch from automatically opening and thus failing to protect the power distribution system.

[0061] Based on this, an embodiment of the present application provides a driving mechanism, which realizes energy storage and then closing of the rotary switch by setting the rotation direction of the operating part when controlling the energy storage part to be opposite to the rotation direction when controlling the rotary switch to be closed, and setting the elastic potential energy of the first elastic part to be greater than the elastic potential energy of the second elastic part.

[0062] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0063] See Figures 2 to 3 The drive mechanism 11 provided in the embodiment of the present application includes a rotating shaft module 111, a lock 112, an operating member 113, a first elastic member 114, and a second elastic member 115. The lock 112 is connected to the rotating shaft module 111. The operating member 113 is installed on the rotating shaft module 111. The first elastic member 114 abuts against the operating member 113 and the rotating shaft module 111. The second elastic member 115 abuts against the operating member 113 and the rotating shaft module 111. The elastic potential energy of the first elastic member 114 is greater than the elastic potential energy of the second elastic member 115. Figure 4 During the first time period t1, the rotary switch is open, and the first elastic member 114 rotates along with the operating member 113 in the first direction X, being locked by the lock catch 112. During the second time period t2, the second elastic member 115 rotates along with the operating member 113 in the second direction Y, driving the rotating shaft module 111 to rotate, closing the rotary switch. The first time period t1 occurs earlier than the second time period t2, and the first direction X is opposite to the second direction Y.

[0064] See Figures 2 to 4 The specific operation process of the driving mechanism 11 in the embodiment of the present application includes the following steps:

[0065] In the first period t1, when the rotary switch is in the open state (the operating member 113 is in Figure 4 When the first elastic member 114 is in the opening position (in the opening position), the end of the first elastic member 114 abutting against the rotating shaft module 111 is fixed by the rotating shaft module 111; the operating member 113 is forced to rotate in the first direction X, and the end of the first elastic member 114 abutting against the operating member 113 rotates along with the operating member 113 in the first direction X and approaches the lock buckle 112, so that the first elastic member 114 is compressed and energy is stored; when the lock buckle 112 locks the first elastic member 114, the operating member 113 rotates to the energy storage position, and the first elastic member 114 completes energy storage.

[0066] It is worth noting that while the first elastic member 114 is storing energy, the operating member 113 simultaneously drives the second elastic member 115 to rotate, causing the second elastic member 115 to store energy. After the first elastic member 114 completes energy storage, it stops applying force to the operating member 113, and the second elastic member 115 releases energy and drives the operating member 113 to reset.

[0067] During the second period t2, when the rotary switch is in the open state (operating member 113 is in Figure 4 When the operating member 113 is in the opening position (in the opening position), the operating member 113 is forced to rotate in the second direction Y to the closing position, and the end of the second elastic member 115 abutting against the operating member 113 rotates in the second direction Y along with the operating member 113. The end of the second elastic member 115 abutting against the rotating shaft module 111 drives the rotating shaft module 111 to rotate in the second direction Y, thereby closing the rotary switch.

[0068] In the above process, assuming that during the first time period t1, the first elastic member 114 has not completed energy storage, the end of the first elastic member 114 abutting against the hinge module 111 is fixed by the hinge module 111, and the end of the first elastic member 114 abutting against the operating member 113 is not locked by the lock 112, but is restricted to a certain position by the operating member 113.

[0069] Based on the above assumptions, during the second period t2, as the second elastic member 115 drives the hinge module 111 to rotate in the second direction Y, the end of the first elastic member 114 abutting the hinge module 111 tends to be driven by the hinge module 111 to rotate in the second direction Y. However, because the elastic potential energy of the first elastic member 114 is greater than the elastic potential energy of the second elastic member 115, the first elastic member 114 exerts a force in the first direction X on the hinge module 111 through the end abutting the hinge module 111 to prevent the hinge module 111 from rotating in the second direction Y. Under the force of the first elastic member 114, the hinge module 111 cannot close the rotary switch.

[0070] In summary, in the drive mechanism 11 of the embodiment of the present application, by setting the rotation direction of the first elastic member 114 when the operating member 113 controls energy storage to be opposite to the rotation direction when controlling the rotary switch to be closed, and setting the elastic potential energy of the first elastic member 114 to be greater than the elastic potential energy of the second elastic member 115, when the rotary switch is closed before the first elastic member 114 has completed energy storage, the first elastic member 114 can apply a force to the hinge module 111 to rotate in the first direction X, thereby preventing the hinge module 111 from being driven by the second elastic member 115 to rotate in the second direction Y, thereby preventing the rotary switch from being closed. When the rotary switch is closed after the first elastic member 114 has completed energy storage, the first elastic member 114 will not prevent the hinge module 111 from being driven by the second elastic member 115 to rotate in the second direction Y, thereby allowing the rotary switch to be closed smoothly. In other words, the drive mechanism 11 of the embodiment of the present application can cause the rotary switch to store energy first and then close.

[0071] Under the premise that the driving mechanism 11 can first store energy and then close the rotary switch, when the power distribution system fails, the tripping mechanism pushes against the lock 112, allowing the first elastic member 114 to be unlocked by the lock 112 and release energy. During the energy release process, the first elastic member 114 can drive the rotating shaft module 111 to rotate in the first direction X, automatically opening the rotary switch and protecting the power distribution system.

[0072] In addition, please refer to the above embodiment. Figures 2 to 4 The specific action process of the driving mechanism 11 also includes the following steps:

[0073] After the second period t2, when the rotary switch is in the closed state (operating member 113 is in Figure 4 When the operating member 113 is in the closed position (in the closed position), the operating member 113 can be forced to rotate in the first direction X to the open position. During the rotation of the operating member 113, the second elastic member 115 can be driven to rotate in the first direction X. During the rotation of the second elastic member 115, the rotating shaft module 111 can be driven to rotate in the first direction X to open the rotary switch.

[0074] It is worth noting that one of the differences between the process of opening the rotary switch and the process of closing the rotary switch is that the ends of the second elastic member 115 that abut the operating member 113 are swapped, and the ends of the second elastic member 115 that abut the rotating shaft module 111 are swapped. Specifically, the portion where the operating member 113 abuts the second elastic member 115 is located between the two ends of the second elastic member 115. For example, during the second time period t2, during the process of closing the rotary switch, assuming that the first end of the second elastic member 115 abuts the operating member 113 and the second end of the second elastic member 115 abuts the rotating shaft module 111; then, after the second time period t2, during the process of opening the rotary switch, the first end of the second elastic member 115 abuts the rotating shaft module 111 and the second end of the second elastic member 115 abuts the operating member 113.

[0075] After the second period t2, see Figure 4 and Figure 5 , when the rotary switch is in the closed state (operating member 113 is in Figure 4 If a fault occurs in the power distribution system (in the closed position), the trip mechanism pushes the latch 112 in the first direction X, causing the latch 112 to unlock the first elastic member 114. After the first elastic member 114 is unlocked by the latch 112, the end of the first elastic member 114 abutting the operating member 113 rotates in the second direction Y, restoring the first elastic member 114 to its normal state. After the end of the first elastic member 114 abutting the operating member 113 rotates a certain angle in the second direction Y, the end is restrained by the operating member 113 in a certain position, causing the end of the first elastic member 114 abutting the rotating shaft module 111 to rotate in the first direction X, automatically opening the rotary switch.

[0076] In the above process, please continue to refer to Figure 5 After the end of the first elastic member 114 abutting the operating member 113 rotates a certain angle in the second direction Y, other components of the rotary switch (for example, the shell) can limit the operating member 113, so that the operating member 113 limits the end of the first elastic member 114 abutting the operating member 113.

[0077] In the above embodiment, the shaft module 111 can be connected to an existing contact mechanism. When the shaft module 111 rotates, it can drive the contact mechanism to open or close, so that the rotary switch is opened when the contact mechanism is opened and closed when the contact mechanism is closed.

[0078] The lock buckle 112 and the shaft module 111 can be connected in a rotating and / or sliding manner, and this embodiment of the present application does not specifically limit this. Figure 3 and Figure 6 As shown, the lock buckle 112 can be rotatably connected to the shaft module 111 through the fixing hole K and the fixing post Z. Alternatively, the lock buckle 112 can be slidably connected to the shaft module 111 through a slider and a chute (not shown in the figure). Alternatively, the shaft module 111 can be provided with a connecting chute and a fixing hole, and the lock buckle 112 can be provided with a fixing post that is compatible with both the chute and the fixing hole. The lock buckle 112 can be slidably connected to the shaft module 111 through the fixing post and the chute, and can be rotatably connected to the shaft module 111 through the fixing post and the fixing hole (not shown in the figure).

[0079] Please combine Figure 3 and Figure 6 The lock buckle 112 may be provided with a locking groove C, which can lock the first elastic member 114. The lock buckle 112 may be provided as an irregular rod-shaped structure, and the locking groove C may be provided on the side wall of the lock buckle 112 facing the first elastic member 114.

[0080] See Figure 2 When the operating member 113 is mounted on the hinge module 111, for example, the hinge module 111 may be provided with a connection hole adapted to the operating member 113, and a portion of the operating member 113 may be embedded in the connection hole. The operating member 113 may also be rotated in the connection hole to be rotationally connected to the hinge module 111. After the operating member 113 is mounted on the hinge module 111, a portion of the operating member 113 may be exposed from the hinge module 111, so as to be rotated in the first direction X or the second direction Y under force.

[0081] The position of the operating member 113 may refer to the position of other parts of the operating member 113 except the rotation center line. For example, a point on the outer wall of the operating member 113 may be in the open position or the closed position.

[0082] The first elastic member 114 and the second elastic member 115 can both be torsion springs or springs. Figure 3 The first elastic member 114 and the second elastic member 115 can be sleeved on the operating member 113, and the operating member 113 can limit the positions of the first elastic member 114 and the second elastic member 115. The first elastic member 114 and the second elastic member 115 can be arranged along the extension direction of the rotation center line of the operating member 113.

[0083] When the first elastic member 114 abuts against the operating member 113 and the rotating shaft module 111 , specifically, both ends of the first elastic member 114 may abut against one surface of the operating member 113 and one surface of the rotating shaft module 111 , respectively.

[0084] When the second elastic member 115 abuts the operating member 113 and the hinge module 111, specifically, both ends of the second elastic member 115 may also abut one surface of the operating member 113 and one surface of the hinge module 111, respectively. Furthermore, during the second period t2 and after the second period t2, the second elastic member 115 abuts different surfaces of the operating member 113 and the hinge module 111.

[0085] The elastic coefficient of the first elastic member 114 may be greater than the elastic coefficient of the second elastic member 115 , so that the elastic potential energy of the first elastic member 114 is greater than the elastic potential energy of the second elastic member 115 .

[0086] by Figures 2 to 5 For example, the first direction X may be a counterclockwise direction, and the second direction Y may be a clockwise direction.

[0087] Furthermore, the four specific actions of the drive mechanism 11 described above constitute a single cycle. Specifically, the first elastic member 114 storing energy, the rotary switch transitioning from the open state to the closed state, the rotary switch transitioning from the closed state to the open state, and the trip mechanism automatically opening the rotary switch all constitute a single operation of the rotary switch. Therefore, the first time period t1 and the second time period t2 constitute two time periods within a single cycle.

[0088] In some embodiments, see Figure 7 and Figure 8 The operating member 113 includes an operating shaft 1131, a lever 1132, and a latch 1133. The operating shaft 1131 is mounted on the hinge module 111. The lever 1132 is connected to the operating shaft 1131. The latch 1133 is located in the rotation path of the lever 1132 and can be pushed by the lever 1132 to lock with the latch 112. The first end of the first elastic member 114 abuts the push arm 1133b. During the second time period t2, the first end of the second elastic member 115 abuts the lever 1132.

[0089] In this example, during the first time period t1, the operating shaft 1131 can be rotated in the first direction X under force, and the lever 1132 can rotate along with the operating shaft 1131 in the first direction X. When the lever 1132 rotates in the first direction X, it can push against the tripping buckle 1133, causing the tripping buckle 1133 to rotate in the first direction X and engage with the lock buckle 112. During the rotation process, the tripping buckle 1133 pushes against the first end of the first elastic member 114, causing the first elastic member 114 to store energy.

[0090] During the second time period t2, the operating shaft 1131 can be forced to rotate in the second direction Y, and the lever 1132 can rotate along with the operating shaft 1131 in the second direction Y. When the lever 1132 rotates in the second direction Y, it can push the first end of the second elastic member 115, causing the first end of the second elastic member 115 to rotate in the second direction Y. This in turn causes the second end of the second elastic member 115 to push the hinge module 111, causing the hinge module 111 to rotate in the second direction Y, thereby closing the rotary switch.

[0091] Specifically, when the operating shaft 1131 is mounted on the hinge module 111, the hinge module 111 can be provided with a connection hole adapted to the operating shaft 1131; a portion of the operating shaft 1131 can be embedded in the connection hole and can rotate within the connection hole. The operating shaft 1131 can be configured as a cylindrical shaft or a prismatic shaft, which is not specifically limited in this embodiment of the present application.

[0092] See Figure 7 When the lever 1132 is connected to the operating shaft 1131, it can be specifically connected to the peripheral wall of the operating shaft 1131; wherein the peripheral wall of the operating shaft 1131 refers to the wall other than the end walls of the operating shaft 1131. The lever 1132 and the operating shaft 1131 can be connected by a fixed connection (for example, integral molding or melting) or an assembly connection (for example, an interference fit), which is not specifically limited in this embodiment of the present application. The lever 1132 can be set as a straight rod structure or a special-shaped structure, etc., which is not specifically limited in this embodiment of the present application.

[0093] Please continue to see Figure 7 The lever 1132 may include an extension arm 1132 a , and during the second period t2 , the first end of the second elastic member 115 may abut against the extension arm 1132 a .

[0094] In the above embodiment, during the first time period t1, the position where the jump button 1133 is pushed by the lever 1132 and the position where the first end of the first elastic member 114 abuts against the jump button 1133 can be various. For ease of understanding, the following exemplary description is given with reference to the accompanying drawings.

[0095] In the first example, see Figure 7 and Figure 8The jump buckle 1133 includes a locking arm 1133a and a push arm 1133b connected to each other; the locking arm 1133a is located on the rotation path of the lever 1132 to be pushed by the lever 1132 and locked with the lock buckle 112; the first end of the first elastic member 114 abuts the push arm 1133b.

[0096] In this example, when lever 1132 rotates, it pushes against locking arm 1133a, causing locking arm 1133a to rotate in the first direction X and engage with latch 112. While lever 1132 pushes against locking arm 1133a, pushing arm 1133b pushes against the first end of first elastic member 114, compressing first elastic member 114. After locking arm 1133a engages latch 112, latch 112 locks locking arm 1133a. Pushing arm 1133b no longer pushes against the first end of first elastic member 114, and first elastic member 114 is no longer compressed, completing energy storage.

[0097] Specifically, the locking arm 1133a and the push arm 1133b can be directly connected or indirectly connected through other components, and this embodiment of the present application does not specifically limit this. For example, when the locking arm 1133a and the push arm 1133b are directly connected, the entire locking arm 1133a and the push arm 1133b can be a rod-shaped structure.

[0098] The locking arm 1133 a can extend toward the lever 1132 to be located on the rotation path of the lever 1132 and be pushed by the lever 1132 .

[0099] The pushing arm 1133b may extend toward the first end of the first elastic member 114. The first end of the first elastic member 114 may abut against an end of the pushing arm 1133b close to the locking arm 1133a, or abut against an end of the pushing arm 1133b away from the locking arm 1133a, or abut between an end of the pushing arm 1133b close to the locking arm 1133a and an end away from the locking arm 1133a, which is not particularly limited in the present application.

[0100] In the second example, see Figure 7 and Figure 8 The jump buckle 1133 includes a locking arm 1133a and a main disk 1133c, the locking arm 1133a is connected to the main disk 1133c; the main disk 1133c is located on the rotation path of the lever 1132, so as to be pushed by the lever 1132 so that the locking arm 1133a is locked with the lock buckle 112; the first end of the first elastic member 114 abuts the main disk 1133c.

[0101] In this example, when lever 1132 rotates, it pushes against main disk 1133c, causing main disk 1133c to rotate in the first direction X. This rotation of main disk 1133c in the first direction X drives locking arm 1133a to rotate in the first direction X, causing locking arm 1133a to engage with latch 112. As lever 1132 pushes against main disk 1133c, main disk 1133c pushes against the first end of first elastic member 114, compressing first elastic member 114. After locking arm 1133a engages latch 112, latch 112 locks locking arm 1133a. Furthermore, main disk 1133c no longer pushes against the first end of first elastic member 114, and first elastic member 114 is no longer compressed, completing energy storage.

[0102] Specifically, the main disk 1133 c can be sleeved on the operating shaft 1131 and can rotate relative to the operating shaft 1131 .

[0103] Part of the main disk 1133 c can extend toward the side where the lever 1132 is located to be located on the rotation path of the lever 1132 , so as to be easily pushed by the lever 1132 .

[0104] The main disk 1133c may be provided with an abutment interface, and the first end of the first elastic member 114 may abut against the inner wall of the abutment interface.

[0105] In the third example, see Figure 7 and Figure 8 The jump buckle 1133 includes a locking arm 1133a, a main disk 1133c and a push arm 1133b. The locking arm 1133a and the push arm 1133b are both connected to the main disk 1133c; the main disk 1133c is located on the rotation path of the lever 1132, so that the locking arm 1133a is pushed by the lever 1132 to lock the locking arm 1133a with the lock buckle 112; the first end of the first elastic member 114 abuts against the push arm 1133b.

[0106] In this example, when lever 1132 rotates in the first direction X, it pushes against main disk 1133c, causing main disk 1133c to rotate in the first direction X. This rotation of main disk 1133c in the first direction X drives locking arm 1133a to rotate in the first direction X, causing locking arm 1133a to engage with latch 112. As lever 1132 pushes against main disk 1133c, pushing arm 1133b pushes against the first end of first elastic member 114, compressing first elastic member 114. After locking arm 1133a engages latch 112, latch 112 locks locking arm 1133a. Furthermore, pushing arm 1133b no longer pushes against the first end of first elastic member 114, and first elastic member 114 is no longer compressed, completing energy storage.

[0107] Specifically, the push arm 1133b and the locking arm 1133a can both be connected to the edge or middle portion of the main disk 1133c, and this application does not make any special restrictions on this.

[0108] A portion of the main disk 1133 c may extend toward the lever 1132 so as to be located on the rotation path of the lever 1132 and be pushed by the lever 1132 .

[0109] The pushing arm 1133b may extend toward the first end of the first elastic member 114. The first end of the first elastic member 114 may abut against an end of the pushing arm 1133b close to the main disk 1133c, or abut against an end of the pushing arm 1133b away from the main disk 1133c, or abut between an end of the pushing arm 1133b away from the main disk 1133c and an end close to the main disk 1133c, which is not limited in the present application.

[0110] It is worth noting that in the above examples, when the locking arm 1133a is locked with the lock buckle 112, the surface of the locking arm 1133a abuts the surface of the locking groove C on the lock buckle 112, compared to the case where the first end of the first elastic member 114 directly abuts the groove surface of the locking groove C. This results in a relatively large abutment area between the locking arm 1133a and the lock buckle 112. This makes it less likely for the locking arm 1133a to slip out of the locking groove C, and the lock buckle 112 exerts a greater locking force on the first elastic member 114.

[0111] In some embodiments, the first elastic member 114 and the second elastic member 115 may be disposed in various positions on the hinge module 111 . For ease of understanding, an exemplary description is given below with reference to the accompanying drawings.

[0112] In the first example, see Figure 2 The hinge module 111 includes an inner cavity Q, the first elastic member 114 and the second elastic member 115 are both located in the inner cavity Q, and the first elastic member 114 and the second elastic member 115 both abut against the cavity wall of the inner cavity Q.

[0113] In this example, during the first period t1 , the end of the first elastic member 114 that contacts the hinge module 111 can be fixed by the wall of the inner cavity Q.

[0114] During the second period t2 , the end of the second elastic member 115 abutting against the hinge module 111 can push against the wall of the inner cavity Q, so that the hinge module 111 rotates in the second direction Y to close the rotary switch.

[0115] It should be noted that when the first elastic member 114 and the second elastic member 115 are both located in the inner cavity Q, the hinge module 111 can cover the first elastic member 114 and the second elastic member 115 to prevent other components outside the hinge module 111 from affecting the first elastic member 114 and the second elastic member 115, which is beneficial to ensure the reliability of the movement of the first elastic member 114 and the second elastic member 115.

[0116] In the second example, the hinge module 111 includes an inner cavity Q, the first elastic member 114 is located outside the hinge module 111 and abuts against the outer wall of the hinge module 111 (not shown in the figure); the second elastic member 115 is located in the inner cavity Q and abuts against the cavity wall of the inner cavity Q.

[0117] In this example, the difference from the first example is that during the first period t1 , the second end of the first elastic member 114 can be fixed by the outer wall of the hinge module 111 .

[0118] Specifically, Figure 2 Taking the placement state in FIG as an example, the first elastic member 114 can be disposed above the hinge module 111 and abut against the upper wall of the hinge module 111.

[0119] In some embodiments, based on the different positions of the first elastic member 114 , the positions at which the lock 112 is rotatably connected to the hinge module 111 are also different, which will be exemplified below with reference to the accompanying drawings.

[0120] For some examples, see Figure 2 and Figure 3 When the first elastic member 114 is located in the inner cavity Q, one end of the lock buckle 112 can be rotatably connected to the cavity wall of the inner cavity Q through the connecting column Z and the connecting hole K.

[0121] In this example, during the first time period t1, when the first end of the first elastic member 114 located in the inner cavity Q is pushed by the operating member 113 and rotates in the first direction X, the lock buckle 112 is also pushed in the inner cavity Q and rotates in the first direction X around the connecting column Z until the lock buckle 112 locks the first elastic member 114.

[0122] It should be noted that when one end of the first elastic member 114 and the lock catch 112 are both located in the inner cavity Q, the first elastic member 114 and the lock catch 112 do not occupy too much space outside the hinge module 111, thereby reducing the overall volume of the drive mechanism 11. In addition, the possibility of interference between the first elastic member 114, the lock catch 112 and other components outside the drive mechanism 11 (for example, the housing of the rotary switch) is reduced.

[0123] In other examples, when the first elastic member 114 is located outside the hinge module 111 , the lock buckle 112 can be rotatably connected to the outer wall of the hinge module 111 (not shown in the figure) through the connecting column Z and the connecting hole K.

[0124] In this example, during the first time period t1, when the first end of the first elastic member 114 located outside the hinge module 111 is pushed by the operating member 113 and rotates in the first direction X, the lock buckle 112 is also pushed outside the hinge module 111 and rotates in the first direction X around the connecting column Z until the lock buckle 112 locks the first elastic member 114.

[0125] Specifically, Figure 2 Taking the placement state in as an example, when the first elastic member 114 can be arranged above the hinge module 111 and abut against the upper wall of the hinge module 111, one end of the lock 112 can be connected to the upper wall of the hinge module 111.

[0126] In some embodiments, see Figure 2 and Figure 3 The other end of the lock buckle 112 is connected to the locking member 116 , and the locking member 116 is used to apply force to the lock buckle 112 so that the lock buckle 112 locks the first elastic member 114 .

[0127] In this embodiment, when the lock buckle 112 is rotationally connected to the hinge module 111 and the first elastic member 114 is locked by the lock buckle 112, the locking member 116 pulls the other end of the lock buckle 112 in the second direction Y, preventing the lock buckle 112 from rotating in the first direction X under the action of an external force (e.g., vibration) and unlocking the first elastic member 114. This improves the stability of the lock buckle 112 when locking the first elastic member 114, ensuring the stability of the first elastic member 114 when in the energy storage state.

[0128] Specifically, the locking member 116 can be a tension spring or a U-shaped spring, etc., which is not limited in this embodiment of the present application. The other end of the locking member 116 can be connected to the hinge module 111, or it can be connected to other components, such as the housing of the rotary switch, etc., which is not specifically limited in this embodiment of the present application.

[0129] The locking member 116 can be connected to the lock buckle 112 in a variety of ways. In one connection method, the lock buckle 112 can be provided with a locking groove, and the first end of the locking member 116 can be embedded in the locking groove. In another connection method, the lock buckle 112 can be provided with a locking hook, and the first end of the locking member 116 can be hooked with the locking hook.

[0130] The locking member 116 can be connected to the hinge module 111 or other components in various ways. For example, in one connection method, the hinge module 111 can be provided with a hook, and the locking member 116 is hooked with the hook. In another connection method, the hinge module 111 can be provided with a hook groove, and the locking member 116 is embedded in the hook groove.

[0131] In some embodiments, based on the different positions of the first elastic member 114 on the hinge module 111 , the position where the first elastic member 114 abuts against the hinge module 111 is also different, which is exemplified below.

[0132] In the first example, combine Figure 9 When the first elastic member 114 is located in the inner cavity Q, a gap is provided in the cavity wall of the inner cavity Q, and the second end of the first elastic member 114 is embedded in the gap.

[0133] In this example, during the first time period t1 , the second end of the first elastic member 114 can be pushed and fixed by the inner wall of the gap.

[0134] Specifically, see Figure 9 The inner cavity Q may be provided with a first protrusion TQ1 and a second protrusion TQ2, with a gap formed therebetween. The second end of the first elastic member 114 is embedded in the gap and abuts against the outer wall of the first protrusion TQ1. Both the first protrusion TQ1 and the second protrusion TQ2 may be rectangular or cylindrical, and this embodiment of the present application does not impose any particular limitation thereto.

[0135] In the second example, when the first elastic member 114 is located outside the hinge module 111 , a gap is provided on the outer wall of the hinge module 111 , and the second end of the first elastic member 114 is embedded in the gap (not shown in the figure).

[0136] In this example, during the first period t1 , the second end of the first elastic member 114 can be pushed and fixed by the outer wall of the hinge module 111 .

[0137] Specifically, the outer wall of the hinge module 111 may be provided with the aforementioned first protrusion TQ1 and second protrusion TQ2, with a gap provided between the first protrusion TQ1 and the second protrusion TQ2, and the second end of the first elastic member 114 abuts against the outer wall of the first protrusion TQ1 (not shown in the figure).

[0138] In some embodiments, see Figure 10 When the second elastic member 115 is located in the inner cavity Q, a cavity wall of the inner cavity Q is provided with a boss TT, and the second elastic member 115 abuts against the boss TT.

[0139] In this example, during the second time period t2, when the first end of the second elastic member 115 located in the inner cavity Q is pushed by the operating member 113 and rotates in the second direction Y, the second end of the second elastic member 115 can drive the rotating shaft module 111 to rotate in the second direction Y by pushing the boss TT, thereby closing the rotary switch.

[0140] After the second period t2, when the second end of the second elastic member 115 located in the inner cavity Q is pushed by the operating member 113 and rotates in the first direction X, the first end of the second elastic member 115 can drive the rotating shaft module 111 to rotate in the first direction X by pushing the boss TT, thereby opening the rotary switch.

[0141] Specifically, if Figure 10 As shown, the boss TT may include a first wall B1 and a second wall B2, which are arranged along the first direction X. During the second period t2, when the rotary switch is closed, the second end of the second elastic member 115 may push against the first wall B1 of the boss TT, causing the hinge module 111 to rotate in the second direction Y. After the second period t2, when the rotary switch is opened, the first end of the second elastic member 115 may push against the second wall B2 of the boss TT, causing the hinge module 111 to rotate in the first direction X.

[0142] It should be noted that when the second elastic member 115 and the boss TT are both located in the inner cavity Q, the second elastic member 115 and the boss TT do not occupy the external space of the hinge module 111, thereby reducing the overall volume of the drive mechanism 11. In addition, the possibility of interference between the second elastic member 115, the boss TT, and other components outside the drive mechanism 11 (e.g., the housing of the rotary switch) is reduced.

[0143] In some embodiments, see Figure 2 、 Figure 9 and Figure 10 The hinge module 111 includes a first hinge 1111 and a second hinge 1112 , which overlap and form an inner cavity Q. The second end of the first elastic member 114 abuts the second hinge 1112 . During the second period t2 , the second end of the second elastic member 115 abuts the first hinge 1111 .

[0144] In this embodiment, during the first period t1, when the rotary switch is in the open state (the operating member 113 is in the Figure 4 In the case of the opening position (in the middle), the second end of the first elastic member 114 is fixed by the second rotating shaft 1112.

[0145] During the second period t2, when the rotary switch is in the open state (operating member 113 is in Figure 4When the rotary switch is in the opening position, the second end of the second elastic member 115 can drive the first rotating shaft 1111 to rotate in the second direction Y to close the rotary switch.

[0146] Specifically, the first rotating shaft 1111 may include a first rotating shaft body and two first connecting protrusions. The two first connecting protrusions may be connected to the edge of the first rotating shaft body and protrude toward the second rotating shaft 1112. The second rotating shaft 1112 may include a second rotating shaft body and two second connecting protrusions. The two second connecting protrusions may be connected to the edge of the second rotating shaft body and protrude toward the first rotating shaft 1111. When the first rotating shaft 1111 and the second rotating shaft 1112 are covered, the two first connecting protrusions are opposite to the two second connecting protrusions one by one and are connected by screws. After the two first connecting protrusions are connected to the two second connecting protrusions, an inner cavity Q may be formed between the first rotating shaft body and the second rotating shaft body.

[0147] When the second end of the first elastic member 114 abuts against the second rotating shaft 1112, for example, see Figure 9 The aforementioned gap can be set on the surface of the second rotating shaft 1112 facing the first rotating shaft 1111.

[0148] When the second end of the second elastic member 115 abuts against the first rotating shaft 1111, for example, see Figure 10 The aforementioned boss TT can be provided on the side of the first rotating shaft 1111 facing the second rotating shaft 1112 .

[0149] The boss TT can be disposed on the edge of the first rotating shaft 1111, or between the edge of the first rotating shaft 1111 and the lever 1132. This embodiment of the present application does not impose any particular limitation on this aspect. It is worth noting that when the boss TT is disposed between the edge of the first rotating shaft 1111 and the lever 1132, the boss TT does not hinder the rotation of the lever 1132 when the lever 1132 rotates with the operating member 113.

[0150] Second, see Figure 11 The present application also provides a rotary switch 1. The rotary switch 1 includes a contact mechanism 12, a trip mechanism 13, and the aforementioned drive mechanism 11. The contact mechanism 12 is connected to a shaft module 111. The trip mechanism 13 can push against a lock 112, causing the lock 112 to release its lock on the first elastic member 114.

[0151] The contact mechanism 12 and the tripping mechanism 13 have been described in detail above and will not be described again here.

[0152] It should be noted that in the aforementioned embodiment, after the tripping mechanism 13 trips the rotary switch due to a power distribution system failure, it is necessary to reset the tripping mechanism 13 so that when the power distribution system fails again, the tripping mechanism 13 can automatically trip the rotary switch 1 again.

[0153] Based on this, in some embodiments, see Figure 4 and Figure 12 In this embodiment of the present application, the drive mechanism 11 further includes a reset lever 117 mounted on the operating member 113. During a third period t3, the reset lever 117 rotates along with the operating member 113 in the first direction X to reset the tripping mechanism 13. The third period t3 is within the first period t1, and the end time of the third period t3 is earlier than the end time of the first period t1.

[0154] In this embodiment, when the third time period t3 is within the first time period t1 and the end time of the third time period t3 is earlier than the end time of the first time period t1, the operating member 113 can first rotate in the first direction X to the reset position to reset the tripping mechanism 13, and then rotate to the energy storage position to store energy in the first elastic member 114. In this way, the complete reset of the tripping mechanism 13 can be ensured.

[0155] If the trip mechanism 13 can be fully reset, at the moment the rotary switch 1 is closed, the trip mechanism 13 will not push against the lock catch 112 due to not being fully reset, causing the first elastic member 114 to be unlocked by the lock catch 112, thereby opening the rotary switch 1. This facilitates smooth closing of the rotary switch 1. Therefore, the rotary switch 1 of this embodiment can only be closed after the trip mechanism 13 is reset. In other words, the rotary switch 1 can be reset first and then closed.

[0156] Furthermore, after the rotary switch 1 is successfully closed and the power distribution system fails, the tripping mechanism 13 can push the lock 112 in the first direction X, so that the lock 112 releases the lock on the first elastic member 114, allowing the first elastic member 114 to release energy to automatically open the rotary switch 1.

[0157] Combining this embodiment with the previous embodiments, it can be seen that the rotary switch 1 of the embodiment of the present application can first store energy, then reset, and finally close. In this way, when the rotary switch 1 is closed and the power distribution system fails, the rotary switch 1 can automatically open and smoothly disconnect the power distribution system.

[0158] Specifically, the reset lever 117 may include a lever body and a lever arm. The lever body is provided with a connection hole for being fitted over the operating member 113 and rotating with the operating member 113 in the first direction X. The lever arm is connected to the edge of the lever body to rotate with the lever body in the first direction X and push against the output end of the trip mechanism 13 to reset the trip mechanism 13.

[0159] Furthermore, in this embodiment, since the reset lever 117 resets the trip mechanism 13 based on the trip mechanism 13 opening the rotary switch, this action of the reset lever 117 resetting the trip mechanism 13 can also occur within a single operation of the rotary switch. In other words, the reset lever 117 resetting the trip mechanism 13 and the four aforementioned specific actions all belong to the same cycle. Therefore, the third time period t3 in this embodiment, like the first time period t1 and the second time period t2 in the aforementioned embodiments, constitutes three time periods within a single cycle of the rotary switch.

[0160] The present application also provides a power distribution system. Figure 13 The power distribution system includes a current detection device 2, a controller 3, and the aforementioned rotary switch 1, which are electrically connected in sequence. The current detection device 2 is used to detect a preset fault in the power distribution system and transmit the preset fault to the controller 3. The controller 3 receives the preset fault and generates a trip signal based on the preset fault. The trip signal is transmitted to the rotary switch 1, causing the rotary switch 1 to automatically trip.

[0161] The current detection device 2 and the controller 3 may be existing technologies and are not described in detail here.

[0162] When the controller 2 sends a trip signal to the rotary switch 1, the trip signal can be sent to the trip mechanism 13 of the rotary switch 1, causing the trip mechanism 13 to push the lock 112, unlocking the first elastic member 114, and then releasing energy of the first elastic member 114 to automatically open the rotary switch 1.

[0163] In this embodiment, under the premise that the rotary switch 1 can automatically trip when a fault occurs in the power distribution system, the power distribution system can be protected by the rotary switch.

[0164] In some embodiments, the preset fault includes at least one of string reverse connection, current backflow, and bus short circuit.

Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein.
