Description

Technical Field

[0001] The present application relates to the technical field of medium and low voltage electrical machinery, and in particular to an integrated operating and driving mechanism of a frame circuit breaker. Background Art

[0002] Circuit breakers are necessary products for power transmission and switching in power supply systems. Their main function is to open and close the circuit breaker in power transmission and transformation systems. The circuit breaker's action process includes energy storage, closing, and opening. Only after energy storage can the opening and closing operations be performed. If the energy storage mechanism fails to store energy or the output torque is large, the closing performance of the circuit breaker will be seriously affected. Therefore, the energy storage mechanism plays an important role in the circuit breaker.

[0003] In order to simultaneously meet the opening and closing actions of manual and automatic circuit breakers, it is generally necessary to install two sets of operating mechanisms, manual and electric, in the circuit breaker. The manual operating mechanism and the electric operating mechanism currently on the market are assembled as two independent entities. This split installation method has many disadvantages. First: Split installation makes the overall structure of the circuit breaker more complicated, requiring more installation space, which is not conducive to the compact design and installation of the equipment. Second: Split installation has problems with signal transmission and control coordination. The linkage between the electric energy storage mechanism and the manual energy storage mechanism is poor, making it difficult to achieve efficient and accurate coordinated control, affecting the overall performance of the circuit breaker.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the circuit breaker with manual and electric energy storage mechanisms installed separately occupies too much installation space, has a complex structure, and is costly. In addition, the two mechanisms have inconsistent synchronization after cooperating with each other, which leads to frequent problems and has obvious shortcomings. Summary of the invention

[0005] In order to realize the integrated installation of electric energy storage and manual energy storage mechanisms, the present application provides an integrated operation and drive mechanism for a frame circuit breaker.

[0006] The present application provides a frame circuit breaker operation drive integrated mechanism adopts the following technical solution: A frame circuit breaker operation and drive integrated mechanism comprises a shell, a frame is arranged inside the shell, a transmission shaft for energy storage is rotatably connected to the frame, and is characterized in that a transmission assembly, a manual operation assembly and an electric operation assembly are arranged inside the shell, the manual operation assembly drives the transmission shaft through the transmission assembly to perform manual energy storage operation, and the electric operation assembly drives the transmission shaft through the transmission assembly to perform electric energy storage operation.

[0007] By adopting the above technical solution, the electric operation component and the manual operation component are connected to the transmission shaft through the transmission component, thereby realizing the integrated design of electric energy storage and manual energy storage. Compared with the traditional circuit breaker in which the manual and electric energy storage mechanisms are installed separately, the integrated design simplifies the internal structure of the circuit breaker, reduces the redundant components and connection structures caused by the separate installation, and effectively saves the installation space. At the same time, the setting of the transmission component realizes the linkage between the electric operation component and the manual operation component, avoiding the problem of poor linkage between the two during separate installation, and can realize efficient and accurate coordinated control.

[0008] Optionally, the transmission assembly includes a ratchet and a ratchet frame coaxially arranged with the transmission shaft, the ratchet is coaxially and fixedly connected to the transmission shaft, the ratchet frame rotatably cooperates with the transmission shaft, a mounting column is provided at the end of the ratchet frame, a driving pawl is rotatably connected to the mounting column, the driving pawl abuts against the tooth groove of the ratchet and is used to drive the ratchet to rotate, a reset member for driving the driving pawl to reset is provided on the frame, and a limit member for preventing the ratchet from rotating in the opposite direction during energy storage is provided on the frame. When storing energy, the electric operation assembly or the manual operation assembly drives the ratchet frame to swing back and forth around the axis of the transmission shaft.

[0009] By adopting the above technical solution, during the energy storage operation, the electric operation component or the manual operation component drives the ratchet frame to swing back and forth around the axis of the transmission shaft, and drives the driving pawl to move during the forward swing of the ratchet frame. At this time, the reset member stores energy, and drives the ratchet to rotate during the movement of the driving pawl. The rotation of the ratchet drives the transmission shaft to rotate forward, thereby realizing the energy storage operation; when the driving action of the driving pawl is completed, the reset member drives the driving pawl to reset and disengage from the ratchet, and at the same time the ratchet frame swings in the opposite direction, and the limit member limits the reverse rotation of the ratchet so that the next driving operation can be carried out, thereby ensuring the continuity of the entire energy storage process.

[0010] Optionally, the hand-operated assembly includes a roller arranged on the ratchet frame away from the end of the mounting column, and a handle is rotatably connected to the outer surface of the frame. A hook groove is provided on the handle, and when the handle rotates toward the roller, the inner side wall of the hook groove contacts the roller and pushes the roller to swing around the axis of the transmission shaft.

[0011] By adopting the above technical solution, when performing manual energy storage, the user presses the handle, and during the process of the handle rotating toward the roller, the inner wall of the hook groove contacts the roller and pushes the roller to swing forward around the axis of the transmission shaft, thereby driving the ratchet frame to rotate on the transmission shaft, and the ratchet frame drives the driving pawl to move the ratchet in the forward direction, the reset member stores energy, and one energy storage of the transmission shaft is completed; after the handle is pressed to the lowest end, the user lifts the handle, the hook groove of the handle gradually disengages from the roller, the reset member resets and pushes the driving pawl to reset, and the process of resetting the driving pawl drives the ratchet frame to reset, so that the next energy storage operation can be carried out smoothly; the hand-operated component continuously drives the ratchet to rotate through the reciprocating pressing action of the handle, and when the transmission shaft reaches the required energy storage state, the manual energy storage process is completed.

[0012] Optionally, the electric operation component includes a motor arranged on the frame, the output shaft of the motor is provided with a driving gear through a transmission gear meshing, the transmission shaft is rotatably connected with a mounting plate, a driving rocker arm is provided on the mounting plate, the driving rocker arm is provided with a waist-shaped groove along the length direction, a rotating pin slidingly matched with the waist-shaped groove is provided on the end face of the driving gear, a pushing arm is provided on the mounting plate, and a pushing block for driving the ratchet frame to swing is provided at the end of the pushing arm away from the mounting plate.

[0013] By adopting the above technical solution, when electric energy storage is performed, the motor is started, and the motor drives the driving gear to rotate through the transmission gear. The driving gear causes the rotating pin to reciprocate in the waist-shaped groove. The displacement change of the rotating pin causes the driving swing rod to swing periodically. The driving swing rod drives the push arm to swing through the connection effect of the mounting plate. When the push arm swings forward, the push block pushes the ratchet frame to rotate around the transmission shaft, and the ratchet frame drives the pawl to move the ratchet forward, thereby realizing an energy storage operation; During the reverse swing of the push arm, the force exerted by the push block on the driving pawl gradually disappears, the reset member drives the driving pawl to reset, the ratchet frame to reset, and at the same time the push arm drives the driving block away from the ratchet frame to ensure the smooth progress of the next energy storage operation; the electric operation component realizes the continuous rotation of the ratchet through the continuous operation of the motor, and when the transmission shaft reaches the required energy storage state, the electric energy storage process ends.

[0014] Optionally, the reset member is a tension spring arranged on the outer surface of the frame, one end of the tension spring is arranged on the outer surface of the frame, and the other end is arranged on the driving pawl. When the driving pawl drives the transmission shaft to store energy by turning the ratchet wheel, the tension spring is in an energy storage state.

[0015] By adopting the above technical solution, during the energy storage operation, the ratchet frame drives the driving pawl to move the ratchet. At this time, the tension spring deforms and stores energy as the driving pawl moves. When the driving pawl completes a driving action, the force acting on the tension spring disappears, and the tension spring releases the elastic force and pulls the driving pawl back to its initial position. During the resetting process of the driving pawl, it disengages from the ratchet and drives the ratchet frame to reset, thereby ensuring the smooth progress of the next energy storage operation and ensuring the continuity and stability of the energy storage operation.

[0016] Optionally, the limiting member is a limiting pawl arranged on the outer surface of the frame, the limiting pawl is engaged with the ratchet wheel, and the limiting pawl is used to prevent the ratchet wheel from rotating in the reverse direction during the energy storage process.

[0017] By adopting the above technical solution, during the energy storage operation, no matter whether the electric operating component or the hand-driven pawl completes a forward shifting action on the ratchet, the limit pawl will be tightly engaged with the ratchet, effectively preventing the ratchet from rotating in the opposite direction during the resetting process of the driving pawl, thereby ensuring that the energy accumulated in the energy storage process will not be lost or retreated, ensuring the smooth progress of the energy storage operation.

[0018] Optionally, an arc-shaped baffle is provided on the ratchet wheel, and the arc-shaped baffle blocks the teeth of the ratchet wheel. When the driving pawl contacts the end surface of the arc-shaped baffle, the energy storage process ends.

[0019] By adopting the above technical solution, during the energy storage process, the driving pawl continuously fluctuates the ratchet wheel to rotate. When the driving pawl rotates to the point where it contacts the end face of the arc-shaped baffle plate, the energy storage process ends. Under the restriction of the arc-shaped baffle plate, the driving pawl separates from the teeth of the ratchet wheel, and the driving pawl cannot continue to drive the ratchet wheel to rotate, thereby avoiding damage to mechanical components or failure of the energy storage mechanism caused by excessive energy storage.

[0020] In summary, the present application includes at least one of the following beneficial technical effects: 1. The embodiment of the present application realizes the integrated design of electric energy storage and manual energy storage by setting a transmission component, an electric operation component and a manual operation component, and connecting the electric operation component and the manual operation component with the transmission shaft through the transmission component, thereby reducing the redundant components and connection structures caused by the split installation, effectively saving the installation space, and at the same time, the setting of the transmission component realizes the linkage between the electric operation component and the manual operation component, avoiding the problem of poor linkage between the two during the split installation, and realizing efficient and accurate coordinated control; 2. The embodiment of the present application provides a reset member, and the setting of the reset member realizes the automatic reset of the driving pawl and the ratchet frame, thereby ensuring the smooth progress of the next energy storage operation and ensuring the continuity and stability of the energy storage operation; 3.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-5 This application is described in further detail.

[0028] An embodiment of the present application discloses an integrated operating and driving mechanism for a frame circuit breaker.

[0029] Reference Figure 1A frame circuit breaker operation and drive integrated mechanism includes a shell 01, a frame 02 is fixedly installed inside the shell 01, the frame 02 includes two supporting plates arranged opposite to each other, a transmission shaft 1 for energy storage operation is rotatably connected between the two supporting plates, a transmission component 2, a manual operating component 3 and an electric operating component 4 are arranged inside the shell 01, the manual operating component 3 drives the transmission shaft 1 through the transmission component 2 to perform manual energy storage operation, and the electric operating component 4 drives the transmission shaft 1 through the transmission component 2 to perform electric energy storage operation.

[0030] The electric operation component 4 and the manual operation component 3 are connected to the transmission shaft 1 through the transmission component 2, realizing the integrated design of electric energy storage and manual energy storage. Compared with the traditional circuit breaker in which the manual and electric energy storage mechanisms are installed separately, the integrated design simplifies the internal structure of the circuit breaker, reduces the redundant components and connection structures caused by the separate installation, and effectively saves the installation space. At the same time, the setting of the transmission component 2 realizes the linkage between the electric operation component 4 and the manual operation component 3, avoiding the problem of poor linkage between the two during separate installation, and can realize efficient and accurate coordinated control.

[0031] Reference Figure 1 and Figure 2 The transmission assembly 2 includes a ratchet 21 and a ratchet frame 22 coaxially arranged with the transmission shaft 1, and the ratchet 21 and the ratchet frame 22 are both rotatably connected to the outer surface of the frame 02, wherein the ratchet 21 is fixedly connected to the transmission shaft 1, and the ratchet frame 22 is rotatably sleeved on the outer surface of the transmission shaft 1, and the ratchet frame 22 is composed of two oppositely arranged plates, and the two plates are respectively arranged on the opposite sides of the ratchet 21, and the end of the ratchet frame 22 is fixedly connected to a mounting column (not shown in the figure), and a driving pawl 23 for driving the ratchet 21 to rotate is arranged on the mounting column, one end of the driving pawl 23 is rotatably matched with the mounting column, and the other end abuts against the tooth groove of the ratchet 21.

[0032] Reference Figure 1 and Figure 2 A reset member is provided on the outer surface of the frame 02, and the reset member is a tension spring 5 provided on the outer surface of the frame 02. One end of the tension spring 5 is fixedly connected to the outer surface of the frame 02, and the other end is fixedly connected to the driving pawl 23. When the driving pawl 23 drives the transmission shaft 1 to store energy by turning the ratchet wheel 21, the tension spring 5 is in an energy storage state.

[0033] Reference Figure 1 and Figure 2 A limiting member is provided on the outer surface of the frame 02, and the limiting member is a limiting pawl 6 provided on the outer surface of the frame 02. The limiting pawl 6 is engaged with the ratchet 21. When the tension spring 5 pulls the driving pawl 23 to reset, the limiting pawl 6 is engaged in the tooth groove of the ratchet 21 to prevent the ratchet 21 from reversing.

[0034] During the energy storage operation, the electric operating assembly 4 or the manual operating assembly 3 drives the ratchet frame 22 to swing back and forth around the axis of the transmission shaft 1, and drives the driving pawl 23 to move during the positive swing of the ratchet frame 22, and drives the pawl 23 to move so that the tension spring 5 stores energy, and at the same time drives the pawl 23 to turn the ratchet 21, and the rotation of the ratchet 21 drives the transmission shaft 1 to rotate positively, thereby realizing the energy storage operation; When the driving pawl 23 completes a driving action, the tension spring 5 releases energy to drive the driving pawl 23 to disengage from the ratchet 21 and reset. When the driving pawl 23 resets, the ratchet frame 22 swings in the opposite direction and resets, so that the next energy storage operation can be performed. At the same time, during the resetting process of the driving pawl 23 and the ratchet frame 22, the limiting pawl 6 is engaged in the tooth groove of the ratchet 21 to prevent the ratchet 21 from rotating in the opposite direction, thereby ensuring that the energy accumulated in the energy storage process will not be lost or retreated, and ensuring the smooth and continuous progress of the energy storage operation.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The hand-operated assembly 3 includes a roller 31 fixedly connected to the ratchet frame 22 away from the end of the mounting column. The outer surface of the frame 02 is rotatably connected to a handle 32. The surface of the handle 32 close to the ratchet frame 22 is provided with a hook groove 321. When no energy is stored, the hook groove 321 is disengaged from the roller 31. When the handle 32 rotates, the inner wall of the hook groove 321 contacts the roller 31 and pushes the roller 31 to swing around the axis of the transmission shaft 1.

[0036] When manually storing energy, the user presses the handle 32. During the process of the handle 32 rotating toward the roller 31, the inner wall of the hook groove 321 contacts the roller 31 and pushes the roller 31 to swing forward around the axis of the transmission shaft 1, thereby driving the ratchet frame 22 to rotate on the transmission shaft 1. The ratchet frame 22 drives the driving pawl 23 to move the ratchet 21. At this time, the tension spring 5 is in an energy storage state, and the rotation of the ratchet 21 drives the transmission shaft 1 to rotate forward, thereby realizing one-time energy storage; When the handle 32 is pressed to the lowest end and the user lifts the handle 32, the hook groove 321 of the handle 32 gradually disengages from the roller 31. At this time, the tension on the tension spring 5 disappears, and the tension spring 5 releases energy to reset, driving the driving pawl 23 to disengage from the ratchet 21 and reset to the initial state. In the process of resetting the driving pawl 23, the ratchet frame 22 and the roller 31 are reset to the initial state. In the process of resetting the driving pawl 23 and the ratchet frame 22, the limiting pawl 6 is engaged in the tooth groove of the ratchet 21 to prevent the ratchet 21 from rotating in the opposite direction. Since the swing amplitude of the roller 31 driven by the handle 32 is limited, the range of rotation of the ratchet 21 driven by the driving pawl 23 is limited. The entire energy storage process requires the user to repeatedly press and lift the handle 32 until the transmission shaft 1 completes energy storage.

[0037] Reference Figure 1 , Figure 4 and Figure 5The electric operation component 4 includes a motor 41 fixedly installed inside the shell 01, the output shaft of the motor 41 is coaxially fixedly connected with a transmission gear 42, the outer surface of the frame 02 is rotatably connected with a driving gear 43 meshing with the transmission gear 42, and a mounting plate 44 is rotatably sleeved on the transmission shaft 1, the mounting plate 44 is arranged on the side of the ratchet frame 22 close to the support plate, and the end of the mounting plate 44 facing the driving gear 43 is fixedly connected with a driving rocker 45, and the driving rocker 45 is provided with a waist-shaped groove 451 along the length direction, and the surface of the driving gear 43 away from the frame 02 is fixedly connected with a rotating pin 46, and the rotating pin 46 is slidably arranged inside the waist-shaped groove 451, and the end of the mounting plate 44 close to the driving pawl 23 is fixedly connected with a pushing arm 47, and the end of the pushing arm 47 away from the mounting plate 44 is fixedly connected with a pushing block 48, and the pushing block 48 is used to push the ratchet frame 22 to swing, and the pushing arm 47, the driving rocker 45, the pushing block 48 and the mounting plate 44 are integrally formed.

[0038] When electric energy storage is performed, the motor 41 is started, and the motor 41 drives the driving gear 43 to rotate through the transmission gear 42. During the continuous rotation of the driving gear 43, the rotating pin 46 reciprocates in the waist-shaped groove 451, and the displacement change between the rotating pin 46 and the waist-shaped groove 451 causes the driving swing rod 45 to swing periodically. The driving swing rod 45 drives the pushing arm 47 to swing within a certain range through the connection effect of the mounting plate 44; When the push arm 47 swings forward, the distance between the push block 48 and the ratchet frame 22 is continuously reduced, and finally the push block 48 abuts against the outer surface of the ratchet frame 22 and pushes the ratchet frame 22 to rotate around the transmission shaft 1, and the ratchet frame 22 drives the pawl to move the ratchet 21 forward, thereby realizing an energy storage operation; When the rotating pin 46 drives the pushing arm 47 to swing in the opposite direction, the force exerted by the pushing block 48 on the ratchet frame 22 gradually decreases, and the tension spring 5 releases energy to drive the driving pawl 23 and the ratchet frame 22 to reset. At the same time, the pushing arm 47 swings in the opposite direction to drive the pushing block 48 to disengage from the ratchet frame 22, so that the next energy storage operation can be carried out smoothly. The electric operation component 4 realizes the continuous rotation of the ratchet 21 through the continuous operation of the motor 41. When the transmission shaft 1 reaches the required energy storage state, the electric energy storage process ends.

[0039] Reference Figure 1 , Figure 4 and Figure 5 The ratchet 21 is fixedly connected with an arc baffle 7, which is integrally formed with the ratchet 21. The arc baffle 7 blocks the teeth of the ratchet 21. When the driving pawl 23 contacts the end face of the arc baffle 7, the energy storage process ends.

[0040] During the energy storage process, the driving pawl 23 continuously fluctuates the ratchet 21 to rotate. When the driving pawl 23 rotates to the point where it contacts the end face of the arc-shaped baffle 7, the energy storage process ends. Under the restriction of the arc-shaped baffle 7, the driving pawl 23 is separated from the teeth of the ratchet 21, and the driving pawl 23 cannot continue to drive the ratchet 21 to rotate, thereby avoiding damage to mechanical components or failure of the energy storage mechanism caused by excessive energy storage.

[0041] The implementation principle of an integrated operation and drive mechanism of a frame circuit breaker in an embodiment of the present application is as follows: the electric operation component 4 and the manual operation component 3 are connected to the transmission shaft 1 through the transmission component 2, thereby realizing an integrated design of electric energy storage and manual energy storage. Compared with the traditional circuit breaker in which the manual and electric energy storage mechanisms are separately installed, the integrated design simplifies the internal structure of the circuit breaker, reduces the redundant components and connection structures caused by the separate installation, and effectively saves the installation space. At the same time, the setting of the transmission component 2 realizes the linkage between the electric operation component 4 and the manual operation component 3, avoiding the problem of poor linkage between the two during separate installation, and can realize efficient and accurate coordinated control.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any 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.
