[0043] A vacuum circuit breaker is a high-voltage switchgear that uses vacuum as an insulating medium and arc-extinguishing medium to interrupt current. Vacuum circuit breakers are used to open and close circuits, especially to quickly cut off current in the event of a fault to protect power systems and other electrical equipment from damage. The performance of the vacuum interrupter, as the interrupting unit of the vacuum circuit breaker, directly affects the performance and service life of the vacuum circuit breaker. Therefore, during the assembly process, it is necessary to focus on the state and stress of the vacuum interrupter.

[0044] See also Figure 1 , Figure 1 A schematic structural diagram of a flipping device 100 provided in some embodiments of the present application is shown. Figure 2 Shows Figure 1 A schematic diagram of a structure in which the flipping device 100 is in a first state and the vacuum circuit breaker is installed on the flipping device 100, Figure 3 Shows Figure 1A schematic diagram of a structure in which the flipping device 100 is in a second state and the vacuum circuit breaker is installed on the flipping device 100, Figure 4 Shows Figure 1 Schematic diagram of the structure in which the flipping device 100 is in the third state and the vacuum circuit breaker is installed on the flipping device 100. The flipping device 100 provided in one embodiment of the present application is used for the vacuum circuit breaker 200. The vacuum circuit breaker 200 has a static end D1 and a dynamic end D2 arranged opposite to each other. The flipping device 100 includes two flipping members 1 arranged at intervals along a first direction F1, the flipping axes of the two flipping members 1 are parallel to each other, and the extension direction F3 of the flipping axis of the flipping member 1 is perpendicular to the first direction F1.

[0045] The structures of the two flipping members 1 can be the same or different. The two flipping members 1 are arranged at intervals along the first direction F1, and the flipping axes of the two flipping members 1 are arranged parallel to each other. During the operation of the flipping device 100, the two flipping members 1 can flip the vacuum circuit breaker 200 in sequence, thereby improving the operating efficiency and reducing the operation time.

[0046] The flip member 1 has a bearing surface M for bearing the vacuum circuit breaker 200, and the two bearing surfaces M are respectively a first bearing surface M1 and a second bearing surface M2, the first bearing surface M1 is used to be detachably connected to the static end D1 of the vacuum circuit breaker 200, and the second bearing surface M2 is used to be detachably connected to the movable end D2 of the vacuum circuit breaker 200. In this way, both flip members 1 have a bearing surface M for bearing the vacuum circuit breaker 200, and the bearing surface M refers to a surface used to support or bear weight, pressure or load. The bearing surface M can be a part of any structure or component, and its design purpose is to withstand forces from above or outside to reduce the risk of local overload.

[0047] The flip device 100 has a first state, a second state, and a third state. In the first state, the first bearing surface M1 is parallel to the first direction F1, and is parallel to the flip axis of the flip member 1 where the first bearing surface M1 is located. In the second state, the first bearing surface M1 and the second bearing surface M2 are both perpendicular to the first direction F1. In the third state, the second bearing surface M2 is parallel to the first direction F1, and is parallel to the flip axis of the flip member 1 where the second bearing surface M2 is located.

[0048] At present, the vacuum circuit breaker is usually arranged vertically as a whole, including a vacuum arc chamber. In the direction of gravity, the moving end of the arc chamber is at the bottom and the static end is at the top. The spring operating mechanism needs to be installed at the bottom of the moving end of the arc chamber. However, during the manufacturing and transportation of the vacuum arc chamber, the static end is usually at the bottom and the moving end is at the top, making it difficult to assemble the spring operating mechanism and the moving end of the arc chamber of the vacuum circuit breaker. The static end refers to the fixed part of the vacuum arc chamber, which is usually connected to the static contact. The static contact is fixed on one side of the arc chamber and does not participate in the movement when the circuit is broken. The moving end mainly includes the moving contact, which is used to connect with the operating mechanism. When the vacuum circuit breaker needs to cut off the circuit, the moving end will move under the drive of the operating mechanism, so that the moving contact is separated from the static contact, thereby generating an arc in a vacuum environment and quickly extinguishing it, thereby cutting off the circuit. Similarly, when closing the circuit, the moving end will drive the moving contact to move toward the static contact and finally contact it to complete the circuit connection.

[0049] When the flipping device 100 is in the first state, the static end D1 of the two opposite ends of the vacuum circuit breaker 200 along the first direction F1 is fixed on the first bearing surface M1. After the vacuum circuit breaker 200 is fixed, the flipping member 1 flips with the vacuum circuit breaker 200, so that the flipping device 100 switches from the first state to the second state, and the vacuum circuit breaker 200 is flipped 90 degrees. Then, the moving end D2 of the vacuum circuit breaker 200 is connected to the second bearing surface M2, and the static end D1 of the vacuum circuit breaker 200 is disconnected from the first bearing surface M1, and then the flipping member 1 flips with the vacuum circuit breaker 200 again by 90 degrees, so that the flipping device 100 is switched from the second state to the third state, and the vacuum circuit breaker 200 is flipped 180 degrees.

[0050] During the whole process, the vacuum circuit breaker 200 is flipped at an angle of 90 degrees each time, and the flipping speed is controllable. The vacuum circuit breaker 200 can be flipped slowly, and the flipping of the vacuum circuit breaker 200 is more continuous. The physical quantities such as the motion trajectory, speed and acceleration of the vacuum circuit breaker 200 change continuously, and the action is smoother, reducing the risk of sudden interruption or jumping of the vacuum circuit breaker 200. Compared with the current use of a crane to hoist and flip the vacuum circuit breaker 200, the flipping angle of the flipping device 100 proposed in the present application is smaller each time, and the vacuum circuit breaker 200 can flip along with the bearing surface M each time it flips. The bearing surface M supports the vacuum circuit breaker 200, reducing the risk of shaking of the vacuum circuit breaker 200 during the flipping process, making the flipping of the vacuum circuit breaker 200 more stable. In this way, the vacuum circuit breaker to be assembled with the static end of the vacuum interrupter at the bottom and the moving end at the top during transportation and manufacturing can be reliably and stably flipped to the state with the static end of the vacuum interrupter at the top and the moving end at the bottom, so that the vacuum circuit breaker and the operating mechanism can be assembled subsequently, thereby achieving reliable assembly and debugging of the vacuum circuit breaker.

[0051] In some embodiments of the present application, continue to refer to Figures 1 to 4 In the first state, the static end D1 of the vacuum circuit breaker 200 is connected to the first bearing surface M1; and / or, in the second state, the static end D1 of the vacuum circuit breaker 200 is connected to the first bearing surface M1, and the movable end D2 of the vacuum circuit breaker 200 is switched to be connected to the second bearing surface M2; and / or, in the third state, the movable end D2 of the vacuum circuit breaker 200 is connected to the second bearing surface M2.

[0052] In the case of "in the first state, the static end D1 of the vacuum circuit breaker 200 is connected to the first bearing surface M1", refer to Figure 2 The vacuum circuit breaker 200 is disposed on the flipping member 1 of the flipping device 100. The vacuum circuit breaker 200 is mounted on the flipping device. The vacuum circuit breaker 200 can change position following the movement of the first bearing surface M1.

[0053] In the case of "in the second state, the static end D1 of the vacuum circuit breaker 200 is connected to the first bearing surface M1, and the dynamic end D2 of the vacuum circuit breaker 200 is switched to be connected to the second bearing surface M2", reference can be made to Figure 3 After the vacuum circuit breaker 200 rotates 90 degrees following the movement of the first bearing surface M1, the vacuum circuit breaker 200 is disconnected from the first bearing surface M1, and the vacuum circuit breaker 200 is connected to the second bearing surface M2, so that the vacuum circuit breaker 200 changes position following the movement of the second bearing surface M2. At this time, the direction in which the moving end D2 of the vacuum circuit breaker 200 points to the static end D1 is parallel to the first direction F1, and the vacuum circuit breaker 200 can be repaired or processed at a specific angle.

[0054] In the case of "in the third state, the movable end D2 of the vacuum circuit breaker 200 is connected to the second bearing surface M2", reference may be made to Figure 4 , so that the vacuum circuit breaker 200 can follow the movement of the second bearing surface M2 and flip again. In this state, the moving end D2 of the vacuum circuit breaker 200 faces downward, so that the moving end D2 of the vacuum circuit breaker 200 can be connected to the operating mechanism.

[0055] According to different scenarios and needs, the flipping device 100 can be switched between the first state, the second state and the third state, so that the vacuum circuit breaker 200 is flipped to different positions, and different operations are performed on the vacuum circuit breaker 200, such as debugging, assembly, installation at a specific angle and maintenance.

[0056] The above-mentioned “in the first state, the static end D1 of the vacuum circuit breaker 200 is connected to the first bearing surface M1”, “in the second state, the static end D1 of the vacuum circuit breaker 200 is connected to the first bearing surface M1, and the movable end D2 of the vacuum circuit breaker 200 is switched to be connected to the second bearing surface M2” and “in the third state, the movable end D2 of the vacuum circuit breaker 200 is connected to the second bearing surface M2” can be arbitrarily combined and set according to actual conditions.

[0057] In some embodiments of the present application, continue to refer to Figure 1 The flip device 100 further includes a rotating shaft 2, two supporting members 3, a connecting member L and a stopper. The rotating shaft 2 is connected to the flip member 1, and the two supporting members 3 are arranged relatively spaced apart along the extension direction F3 of the flip axis of the flip member 1. The rotating shaft 2 has two ends along the extension direction F3 of the flip axis of the flip member 1, one of which is rotatably connected to one supporting member 3; and the other end is rotatably connected to another supporting member 3.

[0058] By designing the rotating shaft 2 and directly installing the flipping member 1 on the rotating shaft 2, the overall structure is simple, and this structural design is compact and can effectively utilize space. The rotating shaft 2 is a core component, and the cooperation between its outer peripheral surface and the first mounting portion enables the vacuum circuit breaker 200 to flip around the rotating shaft 2, thereby achieving functional requirements without occupying too much space. In addition, during the flipping process, the rotating shaft 2, as the rotation center, can withstand the gravity from the vacuum circuit breaker 200 and various forces generated during flipping, wherein the flipping member 1 can be designed to be rotatably connected to the rotating shaft 2, and the flipping member 1 can also be designed to be fixedly connected to the rotating shaft 2.

[0059] At this time, the force applied to the rotating shaft 2 during the flipping process can be transmitted to the two supporting members 3. This force-bearing method can effectively reduce the risk of deformation, wear and even damage of the rotating shaft 2 due to excessive force at a single point, thereby improving the service life and reliability of the rotating shaft 2. In addition, the supporting members 3 provide a stable support point for the rotating shaft 2. When the flipping device 100 is working, no matter how the weight of the flipping member 1 is distributed, the supporting members 3 can keep the rotating shaft 2 in a stable position, reducing the risk of shaking and deviation.

[0060] Continue to refer to Figures 1 to 4 , and combined with reference Figure 5 and Figure 6 , Figure 5 Shows Figure 1 A partial structural diagram of the flipping device 100, Figure 6 Shows Figure 5A partial enlarged view of a in the middle. Along the radial direction of the rotating shaft 2, a first preset hole K1 is opened on the end, and a second preset hole K2 is opened on the connecting member L. The connecting member L is sleeved on the rotating shaft 2, and the connecting member L is fixedly connected to the supporting member 3. The limiting member is used to insert the first preset hole K1 and the second preset hole K2.

[0061] During the process of flipping the vacuum circuit breaker 200 using the flipping device 100 of the present application, the vacuum circuit breaker 200 needs to be fixed on the flipping member 1. At this time, in order to reduce the risk of shaking of the flipping device 100 during the fixed installation process, thereby causing inconvenience in the installation of the vacuum circuit breaker 200, the present application proposes a connecting member L and a limit member.

[0062] Specifically in the present application, the first preset hole K1 and the second preset hole K2 are both through holes, which can be referred to as Figure 5 , a plurality of first preset holes K1 may be provided on the rotating shaft 2, and correspondingly, a plurality of second preset holes K2 may be provided in the circumferential direction of the connecting member L, so that the installation of the limiting member and the first preset holes K1 and the second preset holes K2 is more convenient, and the use efficiency of the flip device 100 is further improved. Specifically, the connecting member L may be a positioning sleeve, and the limiting member may be a positioning pin.

[0063] When the vacuum circuit breaker 200 needs to be fixed to the flip member 1, the rotating shaft 2 needs to stop moving, and the positioning pin can be inserted into the first preset hole K1 and the second preset hole K2, so that the rotating shaft 2 is stationary relative to the connecting member L. Since the connecting member L is fixedly connected to the support member 3, the rotating shaft 2 is stationary relative to the support member 3 at this time, thereby realizing the quick connection and limiting between the rotating shaft 2 and the connecting member L, so that the rotating shaft 2 cannot rotate around its own axis and is in a stationary state, so that the vacuum circuit breaker 200 can be reliably and stably installed on the flip member 1.

[0064] In some embodiments of the present application, continue to refer to Figure 1 The flipping device 100 also includes a reinforcement member J, which has a third end and a fourth end relatively arranged along the extension direction F3 of the flipping axis of the flipping member 1, the third end is connected to one of the two support members 3, and the fourth end is connected to the other of the two support members 3.

[0065] In this way, the reinforcement member J is arranged on the support member 3 to make the support member 3 more stable and reduce the risk of the support member 3 shaking during the operation of the rotating shaft 2. The static end D1 of the reinforcement member J is relatively set along the extension direction F3 of the flip axis of the flip member 1 and is connected to one of the support members 3, and the dynamic end D2 of the reinforcement member J is relatively set along the extension direction F3 of the flip axis of the flip member 1 and is connected to another support member 3, thereby enhancing the supporting force of the support member 3 in the extension direction F3 perpendicular to the flip axis of the flip member 1.

[0066] Please refer to Figure 1The support member 3 includes a first support portion and a second support portion connected to each other, the first support portion is substantially in the shape of a rectangular parallelepiped, and the second support portion is arranged on both sides of the first support portion along the first direction F1. The shape of the second support portion can be, but is not limited to, a triangular prism structure. Figure 1 From the top, the bearing surface M is parallel to the first direction F1, and the cross-sectional area of ​​the support member 3 gradually increases along the direction perpendicular to the bearing surface M and the direction in which the shaft 2 points to the support member 3. This increases the contact area between the part of the support member 3 away from the shaft 2 and the frame 5 or the guide member DX. When the support part is subjected to the pressure from the shaft 2, the pressure can be dispersed to a larger area, thereby reducing the pressure borne per unit area, reducing the local pressure concentration on the frame 5 or the guide member DX, and reducing the risk of problems such as ground subsidence and foundation damage caused by excessive local pressure.

[0067] In some embodiments of the present application, continue to refer to Figure 1 and Figure 2 , along the direction F2 perpendicular to the bearing surface M, a fixing hole KG is opened on the flip member 1, and the fixing hole KG is used to fix the vacuum circuit breaker 200; and / or, along the direction F2 perpendicular to the bearing surface M, a avoidance hole KB is opened on the flip member 1, and the avoidance hole KB is used to avoid the vacuum circuit breaker 200.

[0068] In the case of "a fixing hole KG is provided on the flip member 1 in the direction F2 perpendicular to the bearing surface M, and the fixing hole KG is used to fix the vacuum circuit breaker 200", the vacuum circuit breaker 200 is firmly fixed on the rotating shaft 2 through the fixing hole KG on the flip member 1, reducing the shaking and displacement of the vacuum circuit breaker 200 during flipping, thereby improving the stability and reliability of the entire flip device 100. By adopting the fixing hole KG, a clear positioning and connection point is provided for the installation of the components. The installer only needs to pass the corresponding bolts, screws and other connectors L through the fixing hole KG and tighten them to complete the fixing of the vacuum circuit breaker 200. The operation is simple and quick, which can effectively improve the installation efficiency.

[0069] In the case of "along the direction F2 perpendicular to the bearing surface M, an avoidance hole KB is provided on the flip member 1, and the avoidance hole KB is used to avoid the vacuum circuit breaker 200", for details, continue to refer to Figure 1 and Figure 6 The shape of the flip member 1 can be set to be roughly annular, and the hollow design can avoid the vacuum circuit breaker 200, reducing the risk of friction and wear between the vacuum circuit breaker 200 and the first mounting portion during installation, thereby extending the service life of the vacuum circuit breaker 200. Avoidance holes KB are provided at intervals along the circumferential direction of the bearing surface M on the flip member 1, which can avoid the screws and bolts on the vacuum circuit breaker 200.

[0070] Continue to refer to Figure 1There are multiple fixing holes KG, and the multiple fixing holes KG are arranged at intervals along the circumferential direction of the bearing surface M.

[0071] The fixing holes KG are arranged at intervals along the circumference of the bearing surface M, so that during the installation process of the vacuum circuit breaker 200, multiple fixing holes KG can improve the connection bolts to apply the tightening force evenly from all angles. When the vacuum circuit breaker 200 is subjected to sudden mechanical stress caused by vibration or the like during operation, these fixed points can be subjected to force synergistically. In addition, the layout of the circumferentially arranged fixing holes KG is very regular, which is convenient for quickly locating the installation bolts, greatly shortening the installation time, improving work efficiency, and reducing the probability of installation errors caused by complex and difficult-to-find hole positions. The fixing holes KG are arranged at intervals along the circumference of the bearing surface M, so that the layout of the fixing holes KG is more regular, and more fixing holes KG can be arranged in the limited space of the bearing surface M.

[0072] Specifically in this application, continue to refer to Figure 1 , the structures of the two flipping members 1 are designed to be the same. It can be understood that the same structure of the two flipping members 1 can save production costs, and the torque borne by each flipping member 1 is consistent when the same flipping force is applied to the two flipping members 1 with the same structure, and there will be no situation where a flipping member 1 is subjected to excessive or insufficient force due to structural differences, thereby improving the stability of the flipping and making it more convenient for the operator to apply a flipping force to the flipping member 1. One of the two flipping members 1 can also adopt the above structure, and the other can adopt other structural designs, which is not limited here.

[0073] In some embodiments of the present application, continue to refer to Figure 1 and Figure 4 The flipping device 100 further includes an auxiliary mounting member 4, which is disposed on the bearing surface M. The auxiliary mounting member 4 is used to fix a target portion of the vacuum circuit breaker 200 disposed near the moving end D2.

[0074] The auxiliary mounting part 4 is provided for installing the crank box of the vacuum circuit breaker 200, which is the target part. The crank of the vacuum circuit breaker 200 is an arm-like component with a curved shape, and its shape is usually similar to a curved lever, with a fixed end and a movable end, and the middle part is a curved arm body, which makes it inconvenient to directly set the mounting part on the crank box.

[0075] In some embodiments of the present application, the auxiliary mounting member 4 includes two mounting sub-portions 41, and two limiting portions X arranged one-to-one corresponding to the two mounting sub-portions 41, the two mounting sub-portions 41 are arranged at intervals along the first direction F1, and a corresponding limiting portion X is arranged at one end of the mounting sub-portion 41 away from the bearing surface M in a direction perpendicular to the bearing surface M, and the two limiting portions X extend toward each other along the first direction F1. Among them, the auxiliary mounting member can be set as a channel steel, which is a common steel material used in construction and engineering, a type of steel section, and a long strip of steel. The two mounting sub-portions 41 and the flip member 1 define a limiting space for the crank box to be placed, and the auxiliary mounting member 4 can be installed with other parts of the vacuum circuit breaker 200 that are easy to install.

[0076] In some embodiments of the present application, continue to refer to Figure 1 The flipping device 100 includes a frame 5, and the flipping member 1 is movably connected to the frame 5 along a first direction F1.

[0077] The two flip members 1 can be both arranged to be movably connected to the frame 5 along the first direction F1, or one of the flip members 1 can be arranged to be movably connected to the frame 5 along the first direction F1. In this way, the spacing between the two flip members 1 in the first direction F1 can be changed. In this way, different types of vacuum circuit breakers 200 can be adapted. And when the vacuum circuit breaker 200 is rotated to face the second bearing surface M2, the second bearing surface M2 can be moved away from the first bearing surface M1, thereby avoiding the vacuum circuit breaker 200 and reducing the risk of collision between the vacuum circuit breaker 200 and the second bearing surface M2.

[0078] In some embodiments of the present application, continue to refer to Figure 1 The flipping device 100 further comprises a guide member DX, on which the flipping member 1 is disposed. The frame 5 has a guide rail DG extending along a first direction F1, and the guide member DX is movable and matched with the guide rail DG along the first direction F1.

[0079] By providing the guide rail DG, the flip member 1 can be moved quickly and smoothly in the first direction F1. It is understandable that the guide rail DG and the frame 5 can be integrally formed, or the guide rail DG can be a separate part installed on the frame 5, which is not limited here.

[0080] In some embodiments of the present application, continue to refer to Figures 1 to 4 The guide member DX is provided with a third preset hole K3 along a direction F2 perpendicular to the bearing surface M, and the frame 5 is provided with a fourth preset hole K4 correspondingly along the direction F2 perpendicular to the bearing surface M. At least one of the third preset hole K3 and the fourth preset hole K4 is arranged in plurality along the first direction F1. The flipping device 100 further includes a positioning member, which is used to be inserted into the third preset hole K3 and the fourth preset hole K4.

[0081] Among them, multiple third preset holes K3 can be arranged along the first direction F1, and multiple fourth preset holes K4 can be arranged at intervals along the first direction F1. In this way, when the positioning member is inserted into different third preset holes K3 or different fourth preset holes K4, the guide member DX can be in different positions relative to the frame 5.

[0082] In this way, after the guide member DX slides to the target position relative to the guide groove DC, the guide member DX can be positioned by the positioning member, reducing the risk of the guide member DX shaking relative to the frame 5, thereby facilitating the subsequent fixed installation of the vacuum circuit breaker 200.

[0083] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0084] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
