Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and in particular to a disconnector operating linkage. Background Technology

[0002] In power grid systems, frequent changes in grid operation modes and accelerated urban and rural grid upgrades lead to frequent large, medium, and small-scale power outages and switching operations at substations. During these operations, the variety of disconnectors necessitates the preparation of matching control rods for each type. This results in a large number of control rods stored within substations, many of which are steel structures, each weighing approximately 5 kilograms. This weight makes them difficult to manage, requiring operators to carry multiple different types of control rods at all times, causing inconvenience and increasing costs for companies that need to manufacture or purchase various types of control rods. Summary of the Invention

[0003] The purpose of this invention is to provide a knife switch operating linkage that is easy to carry and has low manufacturing cost.

[0004] To achieve this objective, the embodiments of the present invention adopt the following technical solutions:

[0005] A knife switch operating linkage is provided, including a main body, an operating head, and a drive mechanism. The main body is provided with a first mounting groove for accommodating the operating head. At least two operating heads are provided, and all the operating heads are disposed in the first mounting groove. The drive mechanism is disposed on the main body, and all the operating heads are connected to the drive mechanism. The drive mechanism can selectively drive one of the operating heads to extend out of the first mounting groove or retract into the first mounting groove.

[0006] As a preferred embodiment of the knife switch operating linkage, the driving mechanism includes a driving component and a transmission component. The number of transmission components is the same as the number of operating heads, and each operating head is connected to a set of transmission components. The driving component selectively connects to one of the transmission components, and the driving component drives the transmission component to move, thereby moving the operating head.

[0007] As a preferred embodiment of the switch operating linkage, the drive assembly includes a mounting base, a first motor, a first bevel gear, and a second bevel gear. The main body is provided with a second mounting groove communicating with the first mounting groove. The mounting base is inserted into the second mounting groove. The first motor is mounted on the mounting base. The first bevel gear is mounted on the output shaft of the first motor. The second bevel gear is rotatably mounted on the mounting base. The second bevel gear meshes with the first bevel gear. The second bevel gear is connected to one of the transmission components.

[0008] As a preferred embodiment of the knife switch operating linkage, the transmission assembly includes a third bevel gear, a hinge rod, and a connecting rod. The third bevel gear is rotatably mounted on the main body and meshes with the second bevel gear. The connecting rod is connected to the operating head. One end of the connecting rod away from the operating head is hinged to the hinge rod, and one end of the hinge rod away from the connecting rod is hinged to a non-central position on the side wall of the third bevel gear.

[0009] Pulling the mounting base moves the second bevel gear and the third bevel gear separates. Then, the mounting base is rotated at a certain angle so that the second bevel gear rotates to an appropriate position. The mounting base is then pushed toward the third bevel gear so that the second bevel gear meshes with the third bevel gear. The first motor rotates, driving the second bevel gear to rotate, which in turn drives the third bevel gear to rotate, thereby causing the connecting rod to reciprocate toward the extension direction of the operating head.

[0010] As a preferred embodiment of the knife switch operating linkage, the central axis of all the third bevel gears is set parallel to the central axis of the first bevel gear, and the central axis of the second bevel gear is set perpendicular to the central axis of the first bevel gear.

[0011] As a preferred embodiment of the knife switch operating linkage, the transmission assembly further includes a first locking member. Each of the third bevel gears is provided with a corresponding first locking member. When the second bevel gear separates from the third bevel gear, the first locking member locks the third bevel gear to restrict the rotation of the third bevel gear.

[0012] As a preferred embodiment of the knife switch operating linkage, a pressure-sensitive contactor is also included. The pressure-sensitive contactor is disposed on the third bevel gear and is connected to the first locking member. When the third bevel gear is separated from the second bevel gear, the pressure-sensitive contactor controls the first locking member to lock the third bevel gear.

[0013] As a preferred embodiment of the knife switch operating linkage, it also includes an operating handle, one end of which is connected to the mounting base and the other end is located outside the main body. By rotating the operating handle, the second bevel gear is driven to connect with different transmission components.

[0014] As a preferred embodiment of the knife switch operating linkage, it also includes a limiting member, which is disposed on the end face of the mounting base opposite to the first motor, and the end of the limiting member away from the mounting base abuts against the outer side wall of the main body.

[0015] As a preferred embodiment of the knife switch operating linkage, it further includes a second locking member, which connects the limiting member and the main body.

[0016] The beneficial effects of this invention are as follows: By providing a first mounting groove within the main body, and movably mounting multiple operating heads within the first mounting groove, and by providing a driving mechanism on the main body, one of the operating heads can be selectively driven to extend out of or retract into the first mounting groove. This allows the switch operating linkage to extend different types of operating heads. During operation, only this switch operating linkage needs to be carried to operate multiple different models of switchgear, making it convenient to carry and improving the efficiency of switching or opening. Furthermore, by designing this switch operating linkage, the production of multiple operating linkages is reduced, lowering manufacturing costs and thus improving the economic benefits for the enterprise.

[0022] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0025] like Figures 1 to 2 As shown, this invention discloses a disconnector operating linkage comprising a main body 1, an operating head 2, and a drive mechanism 3. The main body 1 is provided with a first mounting groove 11 for mounting the operating heads 2. At least two operating heads 2 are provided, all of which are located within the first mounting groove 11. All operating heads 2 are connected to the drive mechanism 3, which can selectively drive one of the operating heads 2 to extend out of or retract into the first mounting groove 11. By providing a first mounting groove 11 within the main body 1, and movably mounting multiple operating heads 2 within the first mounting groove 11, and by providing a drive mechanism 3 on the main body 1, the disconnector operating linkage can selectively drive one of the operating heads 2 to extend out of or retract into the first mounting groove 11. This allows the disconnector operating linkage to extend different types of operating heads 2. During operation, only this disconnector operating linkage needs to be carried to operate various types of disconnectors, making it convenient to carry and improving the efficiency of switching or opening. Furthermore, by designing this disconnector operating linkage, the production of multiple operating linkages is reduced, manufacturing costs are lowered, and thus the economic benefits of the enterprise are improved.

[0026] In this embodiment, there are 3 operating heads. Of course, in other embodiments, the number of operating heads 2 can be 2, 4 or other numbers.

[0027] It should be noted that all operating heads 2 can have the same or different shapes. Furthermore, multiple identical operating heads 2 may have different model numbers.

[0028] In this embodiment, the drive mechanism 3 includes a drive component 31 and a transmission component 32. The number of transmission components 32 is the same as the number of operating heads 2, and each operating head 2 is connected to a set of transmission components 32. The drive component 31 selectively connects to one of the transmission components 32, and the drive component 31 drives the transmission component 32 to move, thereby moving the operating head 2. The drive component 31 provides driving force to the operating head 2, and the transmission component 32 can convert the driving force into a force that drives the operating head 2 to move in a fixed direction. During use, the drive component 31 can be rotated to connect with one of the transmission components 32, and the drive component 31 drives the transmission component 32 to move, thereby moving the operating head 2 so that the operating head 2 extends or retracts into the first mounting slot 11, thereby realizing the switching of different operating heads 2.

[0029] Specifically, the drive assembly 31 includes a mounting base 311, a first motor 312, a first bevel gear 313, and a second bevel gear 314. The main body 1 has a second mounting groove 12 communicating with the first mounting groove 11. The mounting base 311 is inserted into the second mounting groove 12. The first motor 312 is mounted on the mounting base 311. The first bevel gear 313 is mounted on the output shaft of the first motor 312. The second bevel gear 314 is rotatably mounted on the mounting base 311 and meshes with the first bevel gear 313. The second bevel gear 314 is also connected to one of the transmission components 32. By mounting the first motor 312, the first bevel gear 313, and the second bevel gear 314 on the mounting base 311, the drive assembly 31 becomes a module. During the rotation of the mounting base 311, the entire drive assembly 31 rotates, allowing the second bevel gear 314 to rotate at different angles and connect with the transmission component 32. The actual working principle of the drive assembly 31 is as follows: the output shaft of the first motor 312 rotates, driving the first bevel gear 313 to rotate. Since the second bevel gear 314 meshes with the first bevel gear 313, the first bevel gear 313 drives the second bevel gear 314 to rotate, thereby causing the second bevel gear 314 to drive the transmission assembly 32 to move.

[0030] Specifically, the transmission assembly 32 includes a third bevel gear 321, a hinge rod 322, and a connecting rod 323. The third bevel gear 321 is rotatably mounted on the main body 1 and meshes with the second bevel gear 314. The connecting rod 323 is connected to the operating head 2. The end of the connecting rod 323 away from the operating head 2 is hinged to the hinge rod 322, and the end of the hinge rod 322 away from the connecting rod 323 is hinged to the non-central position of the side wall of the third bevel gear 321. Pulling the mounting base 311 moves the second bevel gear 314 away from the third bevel gear 321. Then, the mounting base 311 is rotated at a certain angle to drive the second bevel gear 314 to rotate to an appropriate position. The mounting base 311 is then pushed toward the third bevel gear 321 to drive the second bevel gear 314 to mesh with the third bevel gear 321. The first motor 312 rotates, driving the second bevel gear 314 to rotate, which in turn drives the third bevel gear 321 to rotate, thereby driving the connecting rod 323 to reciprocate toward the extension direction of the operating head 2. The hinge rod 322 is hinged to the connecting rod 323 and the third bevel gear 321, and the hinge rod 322 is hinged to the non-central position of the side wall of the third bevel gear 321. The second bevel gear 314 drives the third bevel gear 321 to rotate, thereby driving the hinge rod 322 to move, thereby driving the connecting rod 323 to move in a straight line, and then driving the operating head 2 to extend or retract into the first mounting groove 11.

[0031] Specifically, a guide groove 13 communicating with the first mounting groove 11 and the second mounting groove 12 is provided on the main body 1. The connecting rod 323 is slidably disposed in the guide groove 13. Under the action of the guide groove 13, the connecting rod 323 can move in a fixed direction.

[0032] Specifically, the central axis of all the third bevel gears 321 is parallel to the central axis of the first bevel gear 313, and the central axis of the second bevel gear 314 is perpendicular to the central axis of the first bevel gear 313. This design facilitates the connection between the three bevel gears and provides good transmission performance.

[0033] Specifically, the transmission assembly 32 also includes a first locking member 324. Each third bevel gear 321 is provided with a corresponding first locking member 324. When the second bevel gear 314 separates from the third bevel gear 321, the first locking member 324 locks the third bevel gear 321 to restrict its rotation. It can be understood that the second bevel gear 314 will only mesh with one of the third bevel gears 321, while the drive mechanism 3 is provided with multiple third bevel gears 321. The third bevel gear 321 that is not meshing with the second bevel gear 314 has no locking force, causing it to rotate freely under external force, so that the operating head 2 located in the first mounting groove 11 will move uncontrollably. To avoid the above problems, a first locking member 324 is provided in the main body 1 for each third bevel gear 321. After the third bevel gear 321 is separated from the second bevel gear 314, the first locking member 324 locks the third bevel gear 321, thus restricting the accidental rotation of the third bevel gear 321.

[0034] Specifically, a pressure-sensitive contactor is installed on the third bevel gear 321, and the pressure-sensitive contactor is connected to the first locking member 324. When the third bevel gear 321 is separated from the second bevel gear 314, the pressure-sensitive contactor controls the first locking member 324 to lock the third bevel gear 321. When the third bevel gear 321 is engaged with the second bevel gear 314, the pressure-sensitive contactor is pressed by the second bevel gear 314, causing the pressure-sensitive contactor to send a signal to the first locking member 324 to release the lock on the third bevel gear 321. When the third bevel gear 321 and the second bevel gear 314 are separated, the second bevel gear 314 can no longer press against the pressure-sensitive contactor. At this time, the pressure-sensitive contactor controls the first locking member 324 to lock the third bevel gear 321.

[0035] Optionally, the pressure-sensitive contactor is disposed on the teeth of the third bevel gear 321.

[0036] In one embodiment, the locking or unlocking of the third bevel gear 321 by the first locking member 324 is manually controlled. Specifically, the first locking member 324 is a screw, and the third bevel gear 321 is locked by turning the screw.

[0037] Specifically, the first locking element 324 includes a cylinder 3242 and a brake pad 3241. The cylinder 3242 is mounted on the main body 1, and the brake pad 3241 is mounted on the cylinder rod of the cylinder 3242. The cylinder 3242 drives the brake pad 3241 to press against the third bevel gear 321 to lock the third bevel gear 321; the cylinder 3242 also drives the brake pad 3241 to separate from the third bevel gear 321 to unlock the third bevel gear 321. In this embodiment, the pressure-sensitive contactor is signal-connected to the cylinder 3242. In other embodiments, the cylinder 3242 can be replaced by a hydraulic cylinder or a motor.

[0038] In this embodiment, the knife switch operating linkage also includes an operating handle 4. One end of the operating handle 4 is connected to the mounting base 311, and the other end is located outside the main body 1. By rotating the operating handle 4, the second bevel gear 314 is driven to connect with different transmission components 32. By setting the operating handle 4, the operator can easily rotate the second bevel gear 314 to different angles to mesh with the third bevel gear 321 according to the needs of the application scenario.

[0039] Specifically, a limiting member 5 is provided on the mounting base 311. The limiting member 5 is located on the end face of the mounting base 311 facing away from the first motor 312, and the end of the limiting member 5 away from the mounting base 311 abuts against the outer side wall of the main body 1, so that the mounting base 311 can be inserted into the appropriate position of the second mounting groove 12. It can be understood that during the rotation of the mounting base 311, the mounting base 311 needs to be pulled first to separate the teeth of the second bevel gear 314 and the third bevel gear 321, and then the mounting base 311 is rotated to the appropriate position and then pushed into the second mounting groove 12 to allow the second bevel gear 314 to mesh with the other third bevel gear 321. During this process, the limiting member 5 can limit the depth of the mounting base 311 inserted into the second mounting groove 12 to avoid excessive collision force between the second bevel gear 314 and the third bevel gear 321.

[0040] Specifically, the limiting member 5 is provided with a second locking member 6, which connects the mounting base 311 and the main body 1 to lock the limiting member 5 and the main body 1, thereby locking the mounting base 311 and the main body 1 and preventing the driving component 31 from sliding and disengaging from the second mounting groove 12 when the driving component 31 is working.

[0041] Specifically, the second locking component 6 is a screw, the limiting component 5 is a limiting plate, a first mounting hole is provided at the position where the limiting plate abuts against the main body 1, and a second mounting hole is provided on the side wall of the main body 1. The screw is screwed into the first mounting hole and the second mounting hole to achieve locking between the main body 1 and the limiting plate.

[0042] In other embodiments, the limiting member 5 and the main body 1 are magnetically connected. Specifically, a first magnetic element (not shown in the figures) is provided on the limiting member 5, and a second magnetic element (not shown in the figures) is provided on the main body 1, and the first magnetic element and the second magnetic element are magnetically connected.

[0043] In another embodiment, the drive mechanism 3 is a second cylinder, and the number of second cylinders is the same as the number of operating heads 2. All the second cylinders are set in the second mounting slot 12. Each operating head 2 is connected to a cylinder. When one of the operating heads 2 is needed, the required operating head 2 can be pushed out of the first mounting slot 11 through the second cylinder.

[0044] In the description herein, it should be understood that the terms "upper" and "lower," etc., refer to the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0045] In the description of this specification, references to terms such as "an embodiment" indicate that a specific feature, structure, material, or characteristic associated with that embodiment is included in at least one embodiment or example of the invention. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0047] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of the invention without inventive effort, and these embodiments will all fall within the scope of protection of the present invention.
