[0047] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0048] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, 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. Therefore, they should not be construed as limitations on this utility model.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0050] See Figure 1, Figure 3 and Figure 4 This utility model discloses a longitudinal rotary isolation vacuum circuit breaker, characterized in that it includes an operating mechanism 10 and a movable platform 20; the movable platform 20 includes a support member 21 and a positioning component 22; the operating mechanism 10 is disposed on the support member 21; the positioning component 22 is disposed on the support member 21 and / or the operating mechanism 10; in the length and width directions of the support member 21, the positioning component 22 is used to act on external components to achieve positioning.

[0051] Optional, combined Figure 5 The positioning component 22 includes an elastic element 221 and a positioning element 222. Along the length direction of the support member 21, the positioning element 222 is disposed on the side of the operating mechanism 10, and the elastic element 221 is disposed on the operating mechanism 10 and acts on the positioning element 222. The elastic element 221 provides elastic force to push the positioning element 222 to move and act on the external component. The positioning element 222 restricts the movement of the support member 21 along the length direction of the support member 21.

[0052] In normal conditions, the outer end of the positioning member 222 protrudes from the side of the operating mechanism 10. Under the action of external force, the positioning member 222 can retract towards the middle of the operating mechanism 10. At this time, the elastic member 221 is compressed. After the action of external force is removed, the elastic member 221 provides the positioning member 222 with an outward force to push the positioning member 222 to move away from the operating mechanism 10. In this embodiment, the positioning member 222 is a cylindrical structure with its outer end set as a pointed tip.

[0053] Furthermore, the operating mechanism 10 is disposed at one end of the support member 21; the positioning component 22 also includes a connector 223, which is disposed at the end of the support member 21 away from the operating mechanism 10 along the length direction of the support member 21; the positioning component 222 restricts the movement of the support member 21 along the width direction of the support member 21.

[0054] The connector 223 is also cylindrical, and its end away from the support 21 is a pointed end. Notably, the axial direction of the connector 223 is perpendicular to the axial direction of the positioning member 222.

[0055] More specifically, taking the end of the support member 21 that is far from the operating mechanism 10 as the front end, the support member 21 is set at the front end of the support member 21, while the elastic member 221 and the positioning member 222 are set on both sides of the rear end of the support member 21.

[0056] Optionally, the operating mechanism 10 is provided with an inlet and outlet hole; along the axial direction of the inlet and outlet hole, a support plate 40 is provided in the operating mechanism 10, and a positioning member 222 is simultaneously inserted through the support plate 40 and the inlet and outlet hole. The positioning member 222 is provided with two sets of protrusions 2221, one of which is located between the support plate 40 and the inlet and outlet hole, and the other of which is located on the side of the support plate 40 away from the inlet and outlet hole. An elastic member 221 is sleeved on the positioning member 222 and is located between one of the two protrusions 2221 and the support plate 40.

[0057] For ease of description, one of the protrusions 2221 is referred to as the first group of protrusions, and the other of the protrusions 2221 is referred to as the second group of protrusions. The elastic element 221 is a spring. The positioning element 222 moves into the operating mechanism 10. The first group of protrusions compresses the elastic element 221. Conversely, the compressed elastic element 221 releases and pushes the first group of protrusions, thereby pushing them to move outward. Here, the second group of protrusions is used to prevent the positioning element 222 from falling out of the inlet / outlet hole under the action of the elastic element 221.

[0058] Optionally, it also includes a handle 50. The side of the operating mechanism 10 is provided with an operating groove 101 that is axially arranged along the positioning member 222. The two ends of the handle 50 pass through the operating groove 101 and are each connected to a protrusion 2221.

[0059] The operating groove 101 is an elongated groove, and its height is the same as that of the positioning member 222 in the height direction of the operating mechanism 10. In this embodiment, the handle 50 is U-shaped. The handle 50 can be used to operate the movement of the positioning member 222 in the width direction (horizontal direction) of the support member 21, and the positioning member 222 can enter or exit the middle of the operating mechanism 10.

[0060] Optionally, the elastic element 221, the positioning element 222, the handle 50 and the support plate 40 are arranged as a positioning group; a positioning group is provided on both sides of the operating mechanism 10 in the width direction of the support element 21.

[0061] Two positioning groups are symmetrically arranged on both sides of the operating mechanism 10, thereby forming a symmetrical balanced positioning of the longitudinal rotary isolation vacuum circuit breaker.

[0062] Optionally, the support member 21 includes two parallel support bars 211 and a connecting bar 212; both ends of the connecting bar 212 are connected to the ends of the two support bars 211 that are close to each other; or, the support member 21 includes two parallel support bars 211, a connecting bar 212, and two vertical bars 213; both ends of the connecting bar 212 are connected to the ends of the two support bars 211 that are close to each other, the lower ends of the two vertical bars 213 are each connected to the ends of the two support bars 211 that are close to each other, and both ends of the connecting bar 212 are connected to the two vertical bars 213. The upper end; or, the support member 21 includes two parallel support bars 211, a connecting bar 212, two vertical bars 213 and two mounting bars 215; the two ends of the connecting bar 212 are each connected to the two support bars 211 that are close to each other, the lower ends of the two vertical bars 213 are each connected to the two support bars 211 that are close to each other, the two ends of the connecting bar 212 are each connected to the upper ends of the two vertical bars 213, and each support bar 211 is provided with a mounting bar 215, and the two mounting bars 215 extend in the same direction as the two vertical bars 213.

The support bars 211, connecting bars 212, and vertical bars 213 are preferably hollow quadrilateral profiles. In one embodiment, two support bars 211 and one connecting bar 212 form a U-shaped structure, with the connecting bar 212 near the closed end, and a connector 223 attached to the connecting bar 212. In another embodiment, vertical bars 212 are respectively provided at the same end of the two support bars 211, and the two ends of the connecting bar 212 are connected to the tops of the two vertical bars 213. This type of support member 21 can spatially surround the components to be installed on the support bars 211, improving the protection of the installed components. Similarly, the connector 223 is provided on the connecting bar 212.

[0064] Importantly, in this embodiment, a frame-type support member 21 is constructed using profiles, which provides more space and facilitates the installation, arrangement, and connection of other components.

[0065] In addition, based on the above, the support member 21 also includes two mounting strips 215, each with mounting holes. The operating mechanism 10 is located behind the support member 21 and is fixedly connected to the mounting holes.

[0066] Optionally, the guide groove 2141 is an L-shaped groove, and the two guide grooves 2141 of the two guide bars 214 are arranged facing each other.

[0067] In addition to the aforementioned features, the guide groove 2141 is further configured as an L-shaped groove. The two L-shaped grooves of the two guide grooves 2141 form an inward clamping limit to prevent the two support bars 211 from swinging. At the same time, the L-shaped groove has an open opening to facilitate the installation of the support bars 211. Alternatively, the top of the support bar 211 can be provided with a guide groove 2141, i.e., a U-shaped groove.

[0068] Optional, see below Figure 2 The movable platform 20 also includes a rolling element 23, which is rotatably disposed at the bottom of the support member 21; the support member 21 rolls in the guide groove 2141 via the rolling element 23.

[0069] In this embodiment, the rolling element 23 is preferably a roller, and multiple rolling elements 23 are provided at the bottom of the support element 21. If the bottom of the mounting cavity is a rolling platform and the support element 21 is a platform, then multiple rolling elements 23 are provided at the bottom of the platform, and the rolling elements 23 are rolled on the platform. In the embodiment of the support bar 211 and guide groove 2141, the bottom of the support bar 211 is provided with rolling elements 23, preferably two rolling elements 23 are provided on each support bar 211 in the depth direction, and the rolling elements 23 roll in the guide groove 2141.

[0071] One end of the mounting cavity is open, and guide bars 214 are located on both sides along the length of the mounting cavity. The aforementioned longitudinal rotating isolation vacuum circuit breaker is used in switchgear, which also includes the equipment body and the vacuum circuit breaker 30. According to existing technology, the longitudinal rotating isolation vacuum circuit breaker is isolated from or connected to the equipment body (including contact box, cabinet, pole assembly, etc., which are existing technologies and will not be listed here. The mounting cavity is mainly located in the cabinet, and the pole assembly is closed on the movable platform). Therefore, the vacuum circuit breaker 30 is usually more suitable for maintenance. The vacuum circuit breaker 30 is mounted on the support bar 211, and the vacuum circuit breaker 30 can enter or exit the mounting cavity by moving the support bar 21 within the mounting cavity.

[0072] Importantly, along the length of the mounting cavity, first insertion holes are provided on both side walls, and second insertion holes are provided on the side wall furthest from the opening. When the longitudinally rotating isolation vacuum circuit breaker is in the working position, the positioning member 222 is inserted into the first insertion hole, and the insertion member 223 is inserted into the second insertion hole. Furthermore, in the direction of movement from the maintenance position to the working position, the insertion member 223 is located at the front end of the support bar 211, and the operating mechanism 10 is located at the rear end of the support bar 211.
