[0010] In one embodiment, the flipping device further includes:

[0011] A rotating shaft is connected to a flipping component; a first preset hole is provided on the rotating shaft along the radial direction of the rotating shaft;

[0012] Two support members are arranged at intervals relative to each other along the extension direction of the flipping axis of the flipping member, and the support members are rotatably connected to the rotating shaft;

[0013] A connector, sleeved on the rotating shaft, is fixedly connected to the support; the connector has a second pre-set hole along the radial direction of the rotating shaft; and

[0014] A limiting member is used to insert into the first preset hole and the second preset hole.

[0015] In one embodiment, the flipping device further includes a reinforcing member; along the extension direction of the flipping axis of the flipping member, the reinforcing member has a third end and a fourth end disposed opposite to each other, the third end being connected to one of the two supports and the fourth end being connected to the other of the two supports.

[0016] In one embodiment, a fixing hole is provided on the flip-up member along a direction perpendicular to the bearing surface, the fixing hole being used to fix the vacuum circuit breaker; and / or

[0017] Along the direction perpendicular to the bearing surface, the flipping part is provided with a clearance hole, which is used to avoid the vacuum circuit breaker.

[0018] In one embodiment, the flipping device further includes an auxiliary mounting component disposed on the bearing surface, which is used to fix a target portion of the vacuum circuit breaker located near the moving end.

[0019] In one embodiment, the auxiliary mounting component includes two mounting sub-parts and two limiting parts corresponding to the two mounting sub-parts;

[0020] Two mounting sub-parts are spaced apart along a first direction; a corresponding limiting part is provided at the end of the mounting sub-parts away from the bearing surface along a direction perpendicular to the bearing surface; the two limiting parts extend toward each other along the first direction.

[0021] In one embodiment, the flipping device further includes a frame, and the flipping element is movably connected to the frame along a first direction.

At least one of the third preset hole and the fourth preset hole is provided in a plurality of them in a first direction.

[0024] The flipping device also includes a positioning element for inserting into the third and fourth preset holes.

[0025] The aforementioned flipping device is used to flip a vacuum circuit breaker. The flipping device includes two flipping members spaced apart along a first direction, with their flipping axes parallel to each other. Each flipping member has a bearing surface for supporting the vacuum circuit breaker, the two bearing surfaces being a first bearing surface and a second bearing surface, respectively. When the flipping device is in a first state, the stationary end of the vacuum circuit breaker at its opposite ends along the first direction is fixed to the first bearing surface.

[0026] After the vacuum circuit breaker is secured, the flipping mechanism is rotated along with the vacuum circuit breaker, switching the flipping device from the first state to the second state, thus rotating the vacuum circuit breaker 90 degrees. Next, the moving end of the vacuum circuit breaker is connected to the second bearing surface, while the stationary end is disconnected from the first bearing surface. The flipping mechanism is then rotated another 90 degrees, switching the flipping device from the second state to the third state, achieving a 180-degree rotation of the vacuum circuit breaker. In this way, vacuum circuit breakers that were initially positioned with the stationary end lower and the moving end higher during transportation and manufacturing are reliably and stably rotated to the position with the stationary end higher and the moving end lower, facilitating the assembly of the moving end and the operating mechanism, and enabling reliable assembly and commissioning of the vacuum circuit breaker.

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0039] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0043] A vacuum circuit breaker is a high-voltage switchgear that uses vacuum as both the insulating 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, protecting power systems and other electrical equipment from damage. The vacuum interrupter, as the breaking unit of a vacuum circuit breaker, directly affects the performance and service life of the entire circuit breaker; therefore, its condition and stress distribution must be carefully monitored during assembly.

[0044] See Figure 1 , Figure 1 A schematic diagram of the structure of a flipping device 100 provided in some embodiments of this application is shown. Figure 2 It shows Figure 1 A schematic diagram showing the structure of the switching device 100 in the first state and the vacuum circuit breaker installed in the switching device 100. Figure 3 It shows Figure 1A schematic diagram showing the structure of the switching device 100 in the second state and the vacuum circuit breaker installed in the switching device 100. Figure 4 It shows Figure 1 The diagram shows the structure of the flipping device 100 in its third state and the vacuum circuit breaker mounted on the flipping device 100. An embodiment of this application provides a flipping device 100 used in a vacuum circuit breaker 200. The vacuum circuit breaker 200 has a stationary end D1 and a moving end D2 disposed opposite to each other. The flipping device 100 includes two flipping members 1 spaced apart along a first direction F1, the flipping axes of the two flipping members 1 being parallel to each other, and the extending direction F3 of the flipping axis of the flipping member 1 being perpendicular to the first direction F1.

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

[0046] The flip-over component 1 has a bearing surface M for supporting the vacuum circuit breaker 200. The two bearing surfaces M are a first bearing surface M1 and a second bearing surface M2. The first bearing surface M1 is detachably connected to the stationary end D1 of the vacuum circuit breaker 200, and the second bearing surface M2 is detachably connected to the moving end D2 of the vacuum circuit breaker 200. Thus, both flip-over components 1 have bearing surfaces M for supporting the vacuum circuit breaker 200. The bearing surface M refers to a surface used to support or bear weight, pressure, or load. The bearing surface M can be part of any structure or component, designed to withstand forces from above or external sources to reduce the risk of localized overload.

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

[0048] Currently, vacuum circuit breakers are typically arranged vertically, including a vacuum interrupter. In the direction of gravity, the moving end of the interrupter is at the bottom, and the stationary end is at the top. The spring operating mechanism needs to be installed below the moving end of the interrupter. However, during manufacturing and transportation, the vacuum interrupter is usually positioned with the stationary end at the bottom and the moving end at the top, making it difficult to assemble the spring operating mechanism with the moving end of the interrupter. The stationary end is the fixed part of the vacuum interrupter, usually connected to the stationary contact, which is fixed to one side of the interrupter and does not participate in the movement during circuit breaking. The moving end mainly includes the moving contact, which is used to connect to the operating mechanism. When the vacuum circuit breaker needs to disconnect the circuit, the moving end moves under the drive of the operating mechanism, separating the moving contact from the stationary contact, thereby generating an arc in the vacuum environment and quickly extinguishing it, thus disconnecting the circuit. Similarly, when closing the circuit, the moving end drives the moving contact towards the stationary contact until they finally make contact, completing the circuit connection.

[0049] With the flipping device 100 in the first state, the stationary end D1 of the vacuum circuit breaker 200 is fixed to the first bearing surface M1 at its two opposite ends along the first direction F1. After the vacuum circuit breaker 200 is fixed, the flipping component 1 flips the vacuum circuit breaker 200 together, so that the flipping device 100 switches from the first state to the second state, causing the vacuum circuit breaker 200 to be flipped 90 degrees. Next, the moving end D2 of the vacuum circuit breaker 200 is connected to the second bearing surface M2, and the stationary end D1 of the vacuum circuit breaker 200 is not connected to the first bearing surface M1. The flipping component 1 then flips the vacuum circuit breaker 200 another 90 degrees, so that the flipping device 100 switches from the second state to the third state, achieving a 180-degree flip of the vacuum circuit breaker 200.

[0050] Throughout the process, the vacuum circuit breaker 200 is flipped at an angle of 90 degrees each time, with a controllable flipping speed. The vacuum circuit breaker 200 can be flipped slowly and continuously, with its trajectory, speed, and acceleration changing continuously, resulting in smoother operation and reducing the risk of sudden interruption or jumps. Compared to the current method of using a crane to lift and flip the vacuum circuit breaker 200, the flipping device 100 proposed in this application flips at a smaller angle each time, and the vacuum circuit breaker 200 can flip along with the supporting surface M each time. The supporting surface M supports the vacuum circuit breaker 200, reducing the risk of swaying during the flipping process and making the flipping of the vacuum circuit breaker 200 more stable. In this way, the vacuum circuit breaker to be assembled, which has the stationary 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 where the stationary end of the vacuum interrupter is at the top and the moving end is at the bottom, so that the vacuum circuit breaker and the operating mechanism can be assembled next, and the vacuum circuit breaker can be reliably assembled and debugged.

[0051] In some embodiments of this application, reference continues to be made to Figures 1 to 4 In the first state, the stationary end D1 of the vacuum circuit breaker 200 is connected to the first bearing surface M1; and / or, in the second state, the stationary end D1 of the vacuum circuit breaker 200 is connected to the first bearing surface M1, and the connection is switched to the moving end D2 of the vacuum circuit breaker 200 and the second bearing surface M2; and / or, in the third state, the moving end D2 of the vacuum circuit breaker 200 and the second bearing surface M2 are connected.

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

[0053] In the case where "in the second state, the stationary end D1 of the vacuum circuit breaker 200 is connected to the first bearing surface M1, and the connection is switched to the moving end D2 of the vacuum circuit breaker 200 and the second bearing surface M2", it can be referred 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. Then, the vacuum circuit breaker 200 is connected to the second bearing surface M2, causing the vacuum circuit breaker 200 to change position following the movement of the second bearing surface M2. At this time, the direction from the moving end D2 of the vacuum circuit breaker 200 to the stationary end D1 is parallel to the first direction F1, allowing for maintenance or specific angle adjustments of the vacuum circuit breaker 200.

[0054] In the case where "in the third state, the moving end D2 of the vacuum circuit breaker 200 is connected to the second bearing surface M2", please refer to Figure 4 This allows the vacuum circuit breaker 200 to rotate again following the movement of the second bearing surface M2. In this state, the moving end D2 of the vacuum circuit breaker 200 faces downwards, allowing the moving end D2 of the vacuum circuit breaker 200 to connect with the operating mechanism.

[0055] Depending on the scenario and requirements, the flipping device 100 can switch 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 can be 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 stationary end D1 of the vacuum circuit breaker 200 is connected to the first bearing surface M1", "in the second state, the stationary end D1 of the vacuum circuit breaker 200 is connected to the first bearing surface M1, and the connection is switched to the moving end D2 of the vacuum circuit breaker 200 and the second bearing surface M2", and "in the third state, the moving end D2 of the vacuum circuit breaker 200 is connected to the second bearing surface M2" can be arbitrarily combined and set according to the actual situation.

[0057] In some embodiments of this application, reference continues to be made to Figure 1 The flipping device 100 also includes a rotating shaft 2, two support members 3, a connecting member L, and a limiting member. The rotating shaft 2 is connected to the flipping member 1, and the two support members 3 are arranged at intervals relative to each other along the extension direction F3 of the flipping axis of the flipping member 1. The rotating shaft 2 has two ends along the extension direction F3 of the flipping axis of the flipping member 1, one end of which is rotatably connected to a support member 3; the other end is rotatably connected to another support member 3.

[0058] By designing the rotating shaft 2 and directly mounting the flipping component 1 onto it, the overall structure is simple and compact, effectively utilizing space. The rotating shaft 2, as the core component, allows the vacuum circuit breaker 200 to rotate around it through its outer circumference, fulfilling functional requirements without occupying excessive space. Furthermore, during the rotation process, the rotating shaft 2, as the center of rotation, can withstand the gravity of the vacuum circuit breaker 200 and various forces generated during rotation. The flipping component 1 can be designed to be rotatably connected to the rotating shaft 2, or it can be designed to be fixedly connected to the rotating shaft 2.

[0059] At this time, the force on the rotating shaft 2 during the flipping process can be transmitted to the two support members 3. This force distribution method can effectively reduce the risk of deformation, wear, or even damage to the rotating shaft 2 due to excessive force at a single point, thereby improving the service life and reliability of the rotating shaft 2. Furthermore, the support members 3 provide a stable support point for the rotating shaft 2. When the flipping device 100 is working, regardless of the weight distribution of the flipping component 1, the support members 3 can keep the rotating shaft 2 in a stable position, reducing the risk of swaying and displacement.

[0060] Continue to refer to Figures 1 to 4 and in conjunction with reference Figure 5 and Figure 6 , Figure 5 It shows Figure 1 A partial structural schematic diagram of the inverting device 100. Figure 6 It shows Figure 5A partial enlarged view of point a. A first preset hole K1 is formed at the end along the radial direction of the rotating shaft 2, and a second preset hole K2 is formed on the connecting member L. The connecting member L is sleeved on the rotating shaft 2 and is fixedly connected to the support member 3. A limiting member is used to insert into the first preset hole K1 and the second preset hole K2.

[0061] In the process of flipping the vacuum circuit breaker 200 using the flipping device 100 of this application, the vacuum circuit breaker 200 needs to be fixed on the flipping member 1. In order to reduce the risk of shaking of the flipping device 100 during the fixed installation process, which would lead to inconvenience in installing the vacuum circuit breaker 200, this application proposes a connecting member L and a limiting member.

[0062] Specifically, in this application, both the first preset hole K1 and the second preset hole K2 are through holes, as can be seen from... Figure 5 Alternatively, multiple first preset holes K1 can be opened on the rotating shaft 2, and correspondingly, multiple second preset holes K2 can be opened in the circumferential direction of the connecting member L. This makes it easier to install the limiting member with the first preset holes K1 and the second preset holes K2, further improving the efficiency of the flipping device 100. Specifically, the connecting member L can be a positioning sleeve, and the limiting member can be a positioning pin.

[0063] When it is necessary to fix the vacuum circuit breaker 200 to the flip-up part 1, the rotating shaft 2 needs to stop moving. 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 part L. Since the connecting part L is fixedly connected to the support part 3, the rotating shaft 2 is stationary relative to the support part 3 at this time, thereby realizing the quick connection and limit between the rotating shaft 2 and the connecting part L, so that the rotating shaft 2 cannot rotate around its own axis and is in a stationary state, which makes it easy for the vacuum circuit breaker 200 to be reliably and stably installed on the flip-up part 1.

[0064] In some embodiments of this application, reference continues to be made to Figure 1 The flipping device 100 also includes a reinforcing member J, which has a third end and a fourth end that are disposed opposite to each other 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] Thus, the reinforcing member J is provided 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 stationary end D1 of the reinforcing member J, which is arranged relative to the extension direction F3 of the rotation axis of the rotating member 1, is connected to one of the support members 3. The moving end D2 of the reinforcing member J, which is arranged relative to the extension direction F3 of the rotation axis of the rotating member 1, is connected to the other support member 3. This enhances the supporting force of the support member 3 in the extension direction F3 perpendicular to the rotation axis of the rotating member 1.

[0066] For reference Figure 1The support member 3 includes a first support portion and a second support portion connected to each other. The first support portion is generally rectangular, and the second support portion is disposed on both sides of the first support portion along the first direction F1. The shape of the second support portion may be, but is not limited to, a triangular prism structure. Figure 1 Looking upwards, the bearing surface M is parallel to the first direction F1. Along the direction perpendicular to the bearing surface M and with the rotating shaft 2 pointing towards the support member 3, the cross-sectional area of ​​the support member 3 gradually increases. This increases the contact area between the portion of the support member 3 away from the rotating shaft 2 and the frame 5 or guide member DX. When the support part bears pressure from the rotating shaft 2, the pressure can be distributed over a larger area, thereby reducing the pressure per unit area and reducing local pressure concentration on the frame 5 or guide member DX. This reduces the risk of ground subsidence, foundation damage, and other problems caused by excessive local pressure.

[0067] In some embodiments of this application, reference continues to be made to Figure 1 and Figure 2 Along the direction F2 perpendicular to the bearing surface M, the flipping part 1 has a fixing hole KG for fixing the vacuum circuit breaker 200; and / or, along the direction F2 perpendicular to the bearing surface M, the flipping part 1 has a clearance hole KB for clearing the vacuum circuit breaker 200.

[0068] With the following configuration: "A fixing hole KG is provided on the flipping component 1 along 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 to the rotating shaft 2 on the flipping component 1 through the fixing hole KG. This reduces the shaking and displacement of the vacuum circuit breaker 200 during flipping, thereby improving the stability and reliability of the entire flipping device 100. By using the fixing hole KG, clear positioning and connection points are provided for the installation of components. Installers only need to pass the corresponding bolts, screws, and other connecting parts 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, effectively improving installation efficiency.

[0069] In the case where "a clearance hole KB is provided on the flipping part 1 along the direction F2 perpendicular to the bearing surface M, and the clearance hole KB is used to clear the vacuum circuit breaker 200", please refer to the following for details. Figure 1 and Figure 6 The shape of the flip-up component 1 can be set to approximately circular, hollow design to avoid parts of the vacuum circuit breaker 200, reducing the risk of friction and wear between the vacuum circuit breaker 200 and the first mounting part during installation, thereby extending the service life of the vacuum circuit breaker 200. Furthermore, avoidance holes KB are provided at circumferential intervals along the bearing surface M on the flip-up component 1 to avoid screws, bolts, and other structures on the vacuum circuit breaker 200.

[0070] Continue to refer to Figure 1There are multiple fixing holes KG, which are spaced apart circumferentially along the bearing surface M.

[0071] By arranging the fixing holes KG at intervals along the circumference of the bearing surface M, multiple fixing holes KGs ensure that the connecting bolts can be tightened evenly from various angles during the installation of the vacuum circuit breaker 200. When the vacuum circuit breaker 200 is subjected to sudden mechanical stress caused by vibration during operation, these fixing points can share the force collaboratively. Furthermore, the circumferentially arranged fixing hole KG layout is highly regular, facilitating quick positioning of the installation bolts, greatly shortening installation time, improving work efficiency, and reducing the probability of installation errors caused by complex and difficult-to-find hole positions. Arranging the fixing holes KG at intervals along the circumference of the bearing surface M makes the arrangement of the fixing holes KG more regular, allowing for the placement of more fixing holes KG within the limited space of the bearing surface M.

[0072] Specifically, in this application, please refer to Figure 1 Designing the two flipping components 1 to have identical structures can save production costs. Furthermore, with identical structures, the torque borne by each flipping component 1 is consistent when the same flipping force is applied, preventing situations where one component 1 experiences excessive or insufficient force due to structural differences. This improves the stability of the flipping process and makes it easier for the operator to apply flipping force. Alternatively, one of the two flipping components 1 can adopt the above structure, while the other uses a different design; this is not a limitation.

[0073] In some embodiments of this application, reference continues to be made to Figure 1 and Figure 4 The flipping device 100 also includes an auxiliary mounting component 4, which is located on the bearing surface M and is used to fix the target part of the vacuum circuit breaker 200 near the moving end D2.

[0074] The auxiliary mounting component 4 is provided for mounting the crank arm box of the vacuum circuit breaker 200. The crank arm box is the target part. The crank arm of the vacuum circuit breaker 200 is an arm-shaped component with a curved shape. Its shape is usually similar to a curved lever, with a fixed end and a movable end. The middle part is a curved arm body, which is not convenient to directly set the mounting component on the crank arm box.

[0075] In some embodiments of this application, the auxiliary mounting component 4 includes two mounting sub-parts 41 and two limiting parts X corresponding to each of the two mounting sub-parts 41. The two mounting sub-parts 41 are spaced apart along a first direction F1. Along a direction perpendicular to the bearing surface M, the end of each mounting sub-part 41 away from the bearing surface M has a corresponding limiting part X. The two limiting parts X extend toward each other along the first direction F1. The auxiliary mounting component can be made of channel steel, a common type of steel used in construction and engineering, belonging to the category of structural steel, and is a long strip of steel. The two mounting sub-parts 41 and the flipping component 1 define a limiting space for the placement of the crank arm box. The auxiliary mounting component 4 can be installed with other easily installable parts of the vacuum circuit breaker 200.

[0076] In some embodiments of this application, reference continues to be made to Figure 1 The flipping device 100 includes a frame 5, and the flipping component 1 is movably connected to the frame 5 along a first direction F1.

[0077] Both flipping components 1 can be movably connected to the frame 5 along the first direction F1, or only one flipping component 1 can be movably connected to the frame 5 along the first direction F1. This allows the spacing between the two flipping components 1 in the first direction F1 to be varied. This accommodates different models of vacuum circuit breakers 200. Furthermore, when the vacuum circuit breaker 200 rotates 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 this application, reference continues to be made to Figure 1 The flipping device 100 also includes a guide member DX, and the flipping member 1 is disposed on the guide member DX. The frame 5 has a guide rail DG extending along a first direction F1, and the guide member DX is movably engaged with the guide rail DG along the first direction F1.

[0079] By setting the guide rail DG, the flipping component 1 can move quickly and smoothly in the first direction F1. It is understood that the guide rail DG and the frame 5 can be integrally formed, or the guide rail DG can be a separate part mounted on the frame 5, which is not limited here.

[0080] In some embodiments of this application, reference continues to be made to Figures 1 to 4 The guide member DX has a third preset hole K3 along the direction F2 perpendicular to the bearing surface M, and the frame 5 has 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 multiples along the first direction F1. The flipping device 100 also includes a positioning member for inserting into the third preset hole K3 and the fourth preset hole K4.

[0081] 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 DX slides relative to the guide groove DC to the target position, the guide DX can be positioned by the positioning component, reducing the risk of the guide DX swaying relative to the frame 5 and facilitating the subsequent fixed installation of the vacuum circuit breaker 200.

[0083] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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 merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
