Description

Technical Field

[0002] Isolators can be used to open or close circuits, offering a quick opening and closing function to minimize the effects of arcing. These switchgear are typically constructed so that an operator manually or through other tools operates a lever, which, through a series of interlocking components, causes the movable contact to open or close with the stationary contact. When disconnected, the isolator isolates the non-live components from the live components, creating a clear disconnection point to isolate faulty equipment or equipment undergoing power outages for maintenance. During power outages for electrical equipment maintenance, the equipment being repaired is isolated from the power source to prevent potential safety incidents. Isolators are widely used in power distribution and automation systems in construction, power generation, petrochemicals, and other industries. A common rotary isolator consists of an operating mechanism and a contact system, which includes a movable contact and a stationary contact. The operating mechanism of the isolator uses the movement of a rotating element to drive the movable contact, thereby opening or closing the movable contact. Currently, the operating mechanism of isolators is complex and occupies a large space, hindering product miniaturization. Utility Model Content

[0027] To further illustrate various embodiments, the present invention is provided with accompanying drawings. These drawings form part of the disclosure of this invention and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, those skilled in the art will understand other possible implementations and the advantages of this invention. The components in the figures are not drawn to scale, and similar reference numerals are generally used to represent similar components.

[0028] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0029] like Figure 1-7 As shown, this embodiment provides an isolating switch operating mechanism 1, including a base 10, a main shaft 70, a first gear 80, a second gear 20, an energy storage element 30, a pin shaft 40, a connecting rod 50 and a linkage member 60.

[0030] First gear 80 is coaxially connected to one end of main shaft 70. Main shaft 70 is used to transmit rotational motion, such as the rotation of a handle. This rotational motion is then transmitted to actuate the contact system to open and close the circuit breaker. Specifically, the axis of main shaft 70 is perpendicular to the axis of second gear 20. First gear 80 includes a first bevel gear structure 81, and second gear 20 includes a second bevel gear structure 21. The bevel gear structures of first gear 80 and second gear 20 cooperate to achieve vertical power transmission.

[0031] Reference Figure 6 The second gear 20 and the linkage member 60 are rotatably mounted within the base 10. The second gear 20 and the linkage member 60 are mated together through a plug-in structure, achieving synchronous rotation. The linkage member 60 is provided with a first cylindrical structure 61, which is provided with a first connecting structure 611. The second gear 20 is provided with a second cylindrical structure 22, which is provided with a second connecting structure 221. The first connecting structure 611 and the second connecting structure 221 form a pair of cylindrical and circular holes that can be plugged into and mated with each other, thereby achieving plug-in engagement between the second gear 20 and the linkage member 60.

[0032] In this embodiment, a docking cylinder 611 is provided on the first cylindrical structure 61 , and a docking hole 221 is provided on the second cylindrical structure 22 . The docking cylinder 611 can be plugged into and fitted with the docking hole 221 .

[0033] The linkage member 60 drives the actuating mechanism of the contact system. The rotation of the main shaft 70 realizes the rotation of the linkage member 60, and the rotation of the linkage member 60 is used to actuate the contact system to realize opening and closing.

[0034] This embodiment uses the example of a case where the axis of the main shaft 70 is perpendicular to the axis of the second gear 20 to achieve vertical power transmission. In other embodiments, depending on the specific rotational transmission direction, the axis of the main shaft 70 and the axis of the second gear 20 can be parallel or at a certain angle to each other to achieve power transmission. Alternatively, the main shaft 70 can be directly linked to the linkage member 60, which is also a feasible technical solution.

[0035] The energy storage element 30 can be a compression spring or a tension spring or other energy storage element, such as a gas spring. This embodiment is described using a compression spring as an example. The rotation of the linkage member 60 can actuate the energy storage element 30 to store energy. In this embodiment, the rotation of the linkage member 60 can compress the compression spring to store energy. The energy storage element 30 is sleeved on the connecting rod 50, and the connecting rod 50 is used to guide and limit the energy storage element 30 when compressing to store energy or release energy. One end of the connecting rod 50 is hinged and positioned relative to the base 10. For example, one end of the connecting rod 50 is hinged to the base 10 through a pin 40, so that one end of the connecting rod 50 is hinged and positioned relative to the base 10; the other end of the connecting rod 50 is provided with a slide groove 51, and the connecting groove 51 is provided with a docking cylinder 611 of the linkage member 60, so that the other end of the connecting rod 50 can be rotatably and slidably connected to the linkage member 60. The ends of the energy storage element 30 respectively abut the pin 40 and the first cylindrical structure 61 and / or the second cylindrical structure 22. Of course, the connecting rod 50 can also guide and position the energy storage element 30 in other ways, such as by providing a guide groove on the connecting rod 50, through which the energy storage element 30 is guided and position-limited. In this embodiment, the energy storage element 30 is sleeved on the connecting rod 50, thereby guiding and position-limiting the energy storage element 30 during energy storage or release, resulting in a simpler structure.

[0036] Of course, in some other embodiments, when the energy storage element 30 is a gas spring, the gas spring can be mounted on the connecting rod 50 via an accessory. For example, the gas spring can be mounted on the connecting rod 50 via an additional sleeve.

[0037] When the energy storage element 30 is a tension spring, the tension spring is arranged to have a direction opposite to that of the compression spring in this embodiment, so that the rotation of the linkage member 60 can pull the tension spring to store energy.

[0038] In other embodiments, the chute 51 of the connecting rod 50 can also be provided at the opposite end of the present solution, that is, one end of the connecting rod 50 can be hinged to the linkage member 60, and the other end of the connecting rod 50 can be provided with a chute 51 and slidably connected to the pin 40, which is also a feasible technical solution. However, in this solution, the end of the connecting rod 50 provided with the chute 51 may protrude outward from the base 10 due to the push of the linkage member 60, resulting in the base 10 needing to have a larger volume, which is not conducive to the miniaturization of the product. That is, compared to the connecting rod 50 being rotatably and slidably connected to the base 10, in this embodiment, the connecting rod 50 is rotatably and slidably connected to the linkage member 60, so that the push of the linkage member 60 causes the end of the connecting rod 50 provided with the chute 51 to protrude into the linkage member 60, thereby having a smaller volume and a more compact product. In addition, this solution has a simple structure, is easy to manufacture, and can reduce costs.

[0039] In this embodiment, two sliding sleeves 41 are sleeved on the pin 40, so that one end of the energy storage element 30 does not directly abut the pin 40, but instead abuts the sliding sleeve 41. This reduces the wear of the energy storage element 30 on the pin 40 and makes the operation of the energy storage element 30 more flexible. In other embodiments, the first cylindrical structure 61 and the second cylindrical structure 22 can be replaced with a columnar structure with a non-cylindrical outer surface, for example, a columnar structure with a polygonal outer surface. However, in this embodiment, the use of a cylindrical structure can further make the operation of the energy storage element 30 more flexible.

[0040] The depth of the docking circular hole 221 is less than the length of the docking cylinder 611, thereby providing an assembly gap between the first cylindrical structure 61 and the second cylindrical structure 22. The width of the assembly gap is slightly greater than the thickness of the connecting rod 50, thereby enabling the docking cylinder 611 of the linkage member 60 to be inserted into the chute 51; the connecting rod 50 is positioned in the gap between the first cylindrical structure 61 and the second cylindrical structure 22 in the thickness direction, which is conducive to stabilizing the position of the connecting rod 50 and guiding the movement of the connecting rod 50. Of course, in other embodiments, there is no gap between the first cylindrical structure 61 and the second cylindrical structure 22, that is, the first cylindrical structure 61 and the second cylindrical structure 22 are tightly fitted, and the first cylindrical structure 61 and / or the second cylindrical structure 22 are inserted into the chute 51, which is also a feasible technical solution.

[0041] like Figure 1 As shown, the linkage member 60 starts to rotate in direction B from the first position shown in the figure, and the corresponding rotation direction of the main shaft 70 is direction A. At this time, the first cylindrical structure 61 slides in the slide groove 51, and the distance between the first cylindrical structure 61 and the pin 40 is shortened, thereby compressing the energy storage element 30 to store energy; Figure 2As shown, the linkage member 60 rotates so that the compression degree of the energy storage element 30 reaches the maximum value, so that the energy storage element 30 stores the maximum value. At this time, the linkage member 60 rotates to the dead point position. After reaching this position, the linkage member 60 continues to rotate in direction B, as shown in FIG. Figure 3 As shown, after the linkage member 60 rotates past the dead point, the energy storage element 30 releases energy, driving the linkage member 60 to rotate rapidly, and the linkage member 60 rotates to the position shown in FIG. Figure 3 The second position is shown.

[0042] As mentioned above, since the linkage member 60 drives the actuating mechanism of the contact system, when the linkage member 60 is Figure 1 The first position shown is turned as Figure 3 In the second position shown, the contact state of the contact system switches from the first state to the second state, for example, the contact system switches from the open state to the closed state. The length of the sliding groove 51 on the connecting rod 50 at least partially covers the energy storage compression stroke of the compression spring.

[0043] The energy storage element 30 and connecting rod 50 constitute the energy storage assembly. In this embodiment, two sets of centrally symmetrical energy storage assemblies are provided, each engaging the two cylindrical structures of the linkage member 60. Compared to a single set of energy storage assemblies, this embodiment comprises two sets of energy storage assemblies, centrally symmetrically arranged around the rotation axis of the linkage member 60. This achieves symmetrical compression energy storage, more balanced force distribution, and reduces friction between the main shaft 70 and the base 10, resulting in less wear on components and significantly extending the product's service life.

[0044] The first bevel gear structure 81 of the first gear 80 is a fan-shaped bevel gear structure, and the second bevel gear structure 21 of the second gear 20 is a fan-shaped bevel gear structure, so that the processing of parts is simpler and less material is used. At the same time, it is conducive to fully utilizing the installation space of the base 10, and the miniaturization of the product is improved.

[0045] The end of the chute 51 away from the center of the connecting rod 50 is defined as the outer end. The chute 51 of the connecting rod 50 can be used as a limiting structure to limit the rotation of the linkage member 60. For example, when the linkage member 60 is located at Figure 1 The first position shown or Figure 3 In the second position shown, the cylindrical structure of the linkage member 60 is at the outer end of the slide 51, so that the slide 51 limits the maximum rotation angle of the linkage member 60. Of course, in some other embodiments, the slide 51 does not serve as a limiting structure, and the linkage member 60 is located in the second position shown. Figure 1 The first position shown or Figure 3In the second position shown, the cylindrical structure of the linkage member 60 has not reached the outer end of the chute 51, and the rotation of the linkage member 60 is limited by other structures, which is also a feasible solution. For example, the two cylindrical structures of the linkage member 60 are respectively located at the two ends of the sector bevel gear structure of the second bevel gear structure 21. The two cylindrical structures of the linkage member 60 serve as limiting mechanisms at the meshing ends of the bevel gear structures of the first gear 80 and the second gear 20, thereby limiting the rotation of the linkage member 60.

[0046] Reference Figure 7-8 The main shaft 70 includes a first shaft section 71 and a second shaft section 72. The first shaft section 71 and the second shaft section 72 are intermittently connected in a transmission manner. One end of the second shaft section 72 is in transmission connection with the first shaft section 71.

[0047] A first transmission structure 711 is provided at one end of the first shaft segment 71, a second transmission structure 721 is provided at one end of the second shaft segment 72, and the other end of the second shaft segment 72 is connected to the first gear 80. The first transmission structure 711 and the second transmission structure 721 are a set of shafts with key teeth and shaft holes with key slots that can cooperate with each other for transmission. The central angle corresponding to the key slot is greater than the central angle corresponding to the key teeth, thereby achieving an intermittent transmission connection between the first shaft segment 71 and the second shaft segment 72.

[0048] In this embodiment, a transmission shaft portion 712 is provided at one end of the first shaft segment 71. The transmission shaft portion 712 is provided with key teeth 711. The transmission shaft portion 712 provided with key teeth 711 constitutes the first transmission structure. A transmission shaft hole 722 is provided at one end of the second shaft segment 72. A key slot 721 is provided within the transmission shaft hole 722. The transmission shaft hole 722 provided with the key slot 721 constitutes the second transmission structure. The transmission shaft portion 712 is rotatably matched with the transmission shaft hole 722, and the key tooth 711 is matched in the key groove 721. The central angle N corresponding to the key groove 721 is greater than the central angle M corresponding to the key tooth 711. There is a transmission gap angle K between the key groove 721 and the key tooth 711. The transmission gap angle K is equal to the central angle N corresponding to the key groove 721 minus the central angle M corresponding to the key tooth 711. Therefore, after the first shaft section 71 rotates through the transmission gap angle K, it contacts and transmits with the second shaft section 72, and then drives the second shaft section 72 to rotate. The second shaft section 72 drives the first gear 80 to rotate, thereby driving the second gear 20 and the linkage member 60 to rotate, and then compressing the energy storage element 30 to achieve energy storage.

[0049] When the linkage member 60 rotates to the dead point position, Figure 2As shown, the energy storage element 30 reaches its maximum energy storage value. As the main shaft 70 continues to rotate, the energy storage mechanism passes the dead point and rapidly begins to release energy. Because the first shaft segment 71 and the second shaft segment 72 are intermittently connected, and a transmission gap exists between the first and second shaft segments 71 and 72, during the initial energy release phase, the energy storage mechanism drives the second shaft segment 72 to rotate within the transmission gap angle K. After the second shaft segment 72 rotates beyond the transmission gap angle K, it drives the first shaft segment 71 to rotate. This allows the energy storage mechanism to achieve a greater acceleration during the initial energy release phase, thereby increasing the initial movement speed of the contact system's actuating mechanism and facilitating the closing / opening of the contact system. During the manual closing / opening process using the handle, the movement speed of the human hand is slow compared to the millisecond-level energy release speed of the energy storage element 30 (such as a spring). If there is no transmission gap angle K between the first shaft segment 71 and the second shaft segment 72, the human hand will become part of the resistance in the early stage of energy release of the energy storage element 30. The energy storage element 30 drives the main shaft 70 to rotate, and the main shaft 70 drives the human hand to rotate. The operation feels extremely poor and also affects the energy release speed of the energy storage element 30. Especially during opening, the harm caused by this is extremely great. It slows down the contact separation speed, the arc transfer speed, aggravates the contact erosion, and in severe cases may not be able to interrupt the arc, resulting in a safety risk.

[0050] In this embodiment, the transmission gap angle K is approximately 25°. The number of key teeth 711 and key slots 721 are both 3. Of course, the number of key teeth 711 and key slots 721 can also be other numbers, as long as the number of key teeth 711 and key slots 721 corresponds to each other.

[0051] This embodiment further provides an isolating switch, comprising the isolating switch operating mechanism 1 as described above.
