They are only for the convenience of describing this application 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 application.

[0028] Furthermore, the terms "first" and "second" are used 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 as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0029] Please see Figures 1 to 3 The installation structure 1 provided in the embodiments of this application will now be described. The installation structure 1 is used to install the switch opening and closing detection structure 2 on the switch mechanism 3. The detection structure 2 includes a transmitter 21 and a detection unit 22.

[0030] The mounting structure 1 includes a first mounting component 100 and a second mounting component 200. The first mounting component 100 has a first mounting hole 111, which is configured to cooperate with a first fastener 33 on the flange 32 below the rotating shaft 31 in the knife switch mechanism 3. The first mounting component 100 is used to mount the transmitter 21. The second mounting component 200 is configured to be mounted on the fixing frame 34 of the knife switch mechanism 3. The second mounting component 200 is used to mount two detection units 22, which correspond to the positions of the transmitter 21 in the open and closed states, respectively.

[0031] During assembly, the second mounting component 200 is first installed on the fixing frame 34 of the knife switch mechanism 3, and the first fastener 33 on the flange 32 below the rotating shaft 31 of the knife switch mechanism 3 passes through the first mounting hole 111 of the first mounting component 100 to install the first mounting component 100 on the flange 32, and the transmitter 21 is installed on the first mounting component 100; then, according to the current position of the transmitter 21, one of the detection units 22 is installed on the second mounting component 200 at the position corresponding to the current position of the transmitter 21; the position of the knife switch mechanism 3 is changed, and the other detection unit 22 is installed on the second mounting component 200 at the position corresponding to the current position of the transmitter 21.

[0032] After assembly, the transmitter 21 transmits signals in real time. When the state of the knife switch mechanism 3 changes, the detection unit 22 corresponding to the position of the transmitter 21 can detect the transmitted signal, thereby determining the opening and closing state of the knife switch mechanism 3. The transmitter 21 can transmit magnetic field signals or photoelectric signals. When the transmitter 21 transmits magnetic field signals, the transmitter 21 can be a magnet, permanent magnet, or electromagnet, etc.

[0033] In this embodiment of the application, the installation structure 1, through the provision of the first installation component 100 and the second installation component 200, enables the transmitter 21 and the two detection units 22 to be respectively installed on the rotating shaft 31 and the fixing frame 34 of the knife switch mechanism 3, so that the opening and closing state of the knife switch mechanism 3 can be detected by the transmitter 21 and the two detection units 22. At the same time, by providing a first mounting hole 111 on the first installation component 100 that can be connected to the first fastener 33 on the flange 32 below the rotating shaft 31, the first installation component 100 can be installed using the original first fastener 33 on the flange 32 below the rotating shaft 31. This not only simplifies the installation structure 1, but also ensures that the first installation component 100 is securely installed below the rotating shaft 31, guaranteeing detection accuracy and detection stability.

[0034] In some embodiments, please refer to Figures 1 to 3The first mounting hole 111 extends along the first direction X to make the position of the first mounting component 100 adjustable along the first direction X; wherein, the first direction X is set to intersect the center line of the rotating shaft 31 perpendicularly, that is, the first direction X is parallel to the radial direction of the rotating shaft 31. During assembly, the original first fastener 33 of the flange 32 below the rotating shaft 31 is passed through the first mounting hole 111, so that the first direction X intersects the center line of the rotating shaft 31 perpendicularly. At the same time, the assembly position of the first fastener 33 and the first mounting hole 111 can be adjusted according to different sizes of the knife switch mechanism 3 to be applied to knife switch mechanisms 3 of different sizes. It can be understood that in other embodiments of this application, multiple circular first mounting holes 111 are distributed on the first mounting component 100 at intervals along the first direction X, and the assembly position of the first fastener 33 and the first mounting component 100 is adjusted by different first mounting holes 111 cooperating with the first fastener 33; or, in other embodiments, a single circular first mounting hole 111 can be provided, which is not limited here.

[0035] In some embodiments, please refer to Figure 3 and Figure 4 The first mounting hole 111 penetrates the side of the first mounting component 100 opposite to the second mounting component 200, meaning the first mounting hole 111 opens on the side opposite to the second mounting component 200. This arrangement allows, during assembly, the opening of the first mounting hole 111 to face the first fastener 33 corresponding to the flange 32 below the rotating shaft 31, and the first mounting component 100 to be pushed radially along the rotating shaft 31. This allows the first fastener 33 to be inserted into the first mounting hole 111 through its opening, thereby securing the first mounting component 100 to the flange 32. It is understood that in other embodiments of this application, the side of the first mounting hole 111 opposite to the second mounting component may not be open.

[0036] In some embodiments, please refer to Figure 3 and Figure 4The first mounting component 100 also has a second mounting hole 121 for mounting the transmitter 21. The second mounting hole 121 extends along a second direction Y, which is parallel to the axial direction of the rotating shaft 31. During assembly, the transmitter 21 is locked to the first fastener 33 on the flange 32 through the first mounting hole 111, ensuring that the extension direction of the second mounting hole 121 remains parallel to the axial direction of the rotating shaft 31. Then, the transmitter 21 is mounted on the first mounting component 100 through the second mounting hole 121. The mounting position of the transmitter 21 in the second mounting hole 121 can be adjusted according to actual needs to adjust the axial height position of the transmitter 21 along the rotating shaft 31. It is understood that in other embodiments of this application, multiple circular second mounting holes 121 spaced apart along the second direction Y may also be provided on the first mounting component 100; this is not a unique limitation.

[0037] In some embodiments, please refer to Figure 3 and Figure 4 The first mounting component 100 includes a first mounting plate 110 and a second mounting plate 120, which are perpendicularly connected. The first mounting plate 110 extends from its end connected to the second mounting plate 120 in a first direction X, moving away from the second mounting plate 120. The second mounting plate 120 extends from its end connected to the first mounting plate 110 in a second direction Y, moving away from the first mounting plate 110. A first mounting hole 111 is formed in the first mounting plate 110, extending in the first direction X and penetrating the end of the first mounting plate 110 away from the second mounting plate 120. A second mounting hole 121 is formed in the second mounting hole 121, and the second mounting hole 121 is an oblong hole extending in the second direction Y. In this embodiment, the first mounting component 100 is made by the first mounting plate 110 and the second mounting plate 120 that are perpendicular to each other. This allows the first mounting component 100 to install the transmitter 21 on the flange 32 below the rotating shaft 31, while also minimizing the space occupied by the first mounting component 100 and preventing structural interference with the existing structure of the knife switch mechanism 3.

[0038] In some embodiments, please refer to Figure 3 , Figure 5 and Figure 6The second mounting component 200 has an arc-shaped groove 211, which is coaxial with the rotating shaft 31. The arc-shaped groove 211 is used to mount two detection units 22, and the positions of the two detection units 22 along the arc-shaped groove 211 are adjustable. Specifically, during assembly, the second mounting component 200 is first mounted on the fixing frame 34 of the switch mechanism 3, so that the center line of the arc-shaped groove 211 coincides with the center line of the rotating shaft 31; then, the two detection units 22 are installed in the arc-shaped groove 211 according to the open and closed states of the switch mechanism 3 of the transmitter 21, respectively. Specifically, the installation positions of the two detection units 22 in the arc-shaped groove 211 can be adjusted according to different opening and closing angles of the switch mechanism 3.

[0039] Specifically, the detection structure 2 also includes two detection unit mounting boxes 24, which are respectively mounted on the arc-shaped grooves 211 by second fasteners, and the two detection units 22 are respectively mounted in the two detection unit mounting boxes 24. It can be understood that in other embodiments of this application, two arc-shaped grooves 211 may also be provided in the second mounting component 200, with each arc-shaped groove 211 used to mount two detection units 22, and the two arc-shaped grooves 211 having equal radii and being coaxially arranged. Furthermore, by making the position of the detection units 22 along the arc-shaped grooves 211 adjustable, the position of the two detection units 22 can be adjusted according to different opening and closing angles of the knife switch mechanism 3, thereby improving the adaptability of the mounting structure 1.

[0040] In some embodiments, please refer to Figure 3 and Figure 5 The second mounting component 200 includes a mounting platform 210 and at least one connector 220. An arc-shaped groove 211 is formed on the mounting platform 210, and the at least one connector 220 connects the mounting platform 210 and the mounting bracket 34 in an adjustable manner. The mounting platform 210 and the at least one connector 220 allow the mounting platform 210 to be positioned around the rotating shaft 31, and the arc-shaped groove 211 on the mounting platform 210 to be positioned around the rotating shaft 31. This allows the two detection units 22 mounted on the arc-shaped groove 211 to detect whether the transmitter 21 on the rotating shaft 31 is in an open or closed state. Simultaneously, the at least one connector 220 connects the mounting platform 210 and the mounting bracket 34, and the connection position of the connector 220 with the mounting platform 210 and the mounting bracket 34 is adjustable, thus meeting the different installation requirements of the mounting platform 210 and adapting to different sizes of knife switch mechanisms 3.

[0041] In some embodiments, please refer to Figure 3 , Figures 5 to 7The connector 220 and the mounting platform 210 are relatively adjustable along the third direction M and the fourth direction N, and the connector 220 and the fixing frame 34 are relatively adjustable along the third direction M; wherein, the third direction M is parallel to the midpoint line 2110 of the arc groove 211, and the fourth direction N is perpendicular to the midpoint line 2110 of the arc groove 211.

[0042] The midpoint 2110 of the arc groove 211 refers to the line passing through the center of the arc groove 211 and perpendicular to its radius. This midpoint 2110 divides the arc groove 211 into two symmetrical parts, as shown in the figure. The fourth direction N is perpendicular to the midpoint 2110 of the arc groove 211, and the third direction M is parallel to the midpoint 2110 of the arc groove 211. This arrangement ensures that when using rotating shafts 31 with different diameters, the arc groove 211 needs to be moved parallel to its midpoint 2110. This means adjusting the installation positions of the connector 220 and the mounting platform 210 along the third direction M, as well as the installation positions of the connector 220 and the fixing frame 34 along the third direction M, so that the arc groove 211 can remain coaxial with the rotating shaft 31 while its position is adjusted. Furthermore, by adjusting the position of the connector 220 and the mounting platform 210 along the fourth direction N, the installation requirements of the fixing bracket 34 with different widths along the fourth direction N can be met.

[0043] In some embodiments, please refer to Figure 5 and Figure 6 The mounting platform 210 has a first mounting groove 212 extending along a fourth direction N, and the connector 220 has a second mounting groove 2211 extending along a third direction M. The connector 220 and the mounting platform 210 are connected through the first mounting groove 212 and the second mounting groove 2211. The first mounting groove 212 and the second mounting groove 2211 are configured such that when it is necessary to adjust the position of the connector 220 and the mounting platform 210 along the third direction M and / or the fourth direction N, the connector 220 can be moved relative to the mounting platform 210 along the third direction M and / or the fourth direction N, so that different positions of the first mounting groove 212 along the fourth direction N and different positions of the second mounting groove 2211 along the third direction M correspond. Finally, it is locked with a third fastener. It is understood that in other embodiments of this application, the first mounting groove 212 may also be formed on the connector 220, and the second mounting groove 2211 may be formed on the mounting platform 210; this is not a unique limitation.

[0044] In some embodiments, please refer to Figure 5The mounting platform 210 has at least two first mounting slots 212 spaced apart along the fourth direction N. The second mounting component 200 includes at least two connectors 220, each connector 220 having a second mounting slot 2211. By providing at least two first mounting slots 212 and at least two connectors 220, the mounting platform 210, which has a larger width along the fourth direction N, and the fixing frame 34, which also has a larger width along the fourth direction N, can be connected, ensuring a stable connection and avoiding the use of connectors 220 with larger dimensions along the fourth direction N, thus reducing the material cost of the connectors 220. It is understood that in other embodiments of this application, only one connector 220 may be provided; this is not a limiting factor.

[0045] Please see Figure 6 The mounting platform 210 is recessed in an arc shape on the side facing the rotating shaft 31 to accommodate the movement trajectory of the knife switch mechanism 3 during its opening and closing motion.

[0046] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 5 The detection structure 2 also includes a receiving unit 23, which is communicatively connected to the detection unit 22. The receiving unit 23 is used to receive, process and output the status signal transmitted by the detection unit 22. Specifically, it feeds back the processed status signal to the controller of the entire knife switch mechanism 3 so as to control the knife switch mechanism 3 or its opening and closing state.

[0047] In some embodiments, please refer to Figure 3 and Figure 5 The receiving unit 23 is installed between two first mounting slots 212. The detection structure 2 also includes a receiving unit mounting box 25. The receiving unit mounting box 25 has third mounting holes 251 on opposite sides along the fourth direction N. The two third mounting holes 251 are locked one-to-one with the two first mounting slots 212, thereby installing the receiving unit 23 on the mounting platform 210 and allowing adjustment of the installation position of the receiving unit 23 along the fourth direction N. In addition, a communication connection can be formed between the detection unit 22 and the receiving unit 23 via wires.

[0048] In some embodiments, please refer to Figure 5 and Figure 7 The connector 220 is provided with at least two second mounting slots 2211, which are spaced apart along the fourth direction N. The at least two second mounting slots 2211 are locked to the first mounting slot 212 at different positions along the fourth direction N by a third fastener, thereby improving the installation reliability of the connector 220 on the mounting platform 210.

[0049] In some embodiments, please refer to Figure 1 , Figure 5 and Figure 7 The connector 220 also has a third mounting groove 2221 extending along a third direction M. The third mounting groove 2221 is used to engage and lock with a fourth mounting hole 341 on the fixing frame 34, thereby making the position of the connector 220 relative to the fixing frame 34 adjustable along the third direction M. It is understood that in other embodiments of this application, the third mounting groove 2221 may also be formed on the fixing frame 34 and the fourth mounting hole 341 may be formed on the connector 220, which is not the only one here.

[0050] Specifically, the third mounting slot 2221 is set with an opening at one end opposite to the mounting platform 210, which facilitates the installation of the connector 220 on the fixing bracket 34.

[0051] In some embodiments, please refer to Figure 7 The connector 220 includes a first connecting plate 221, a second connecting plate 222, and a third connecting plate 223. The first connecting plate 221 and the second connecting plate 222 are parallel to each other, and the third connecting plate 223 is connected between the first connecting plate 221 and the second connecting plate 222. The third connecting plate 223 is perpendicular to both the first connecting plate 221 and the second connecting plate 222. A second mounting groove 2211 is formed in the first connecting plate 221. The first connecting plate 221 is stacked below the mounting platform 210, and a third fastener passes through the first mounting groove 212 and the second mounting groove 2211 in sequence to lock the mounting platform 210 and the first connecting plate 221. The first connecting plate 221 and the second connecting plate 222 are spaced apart along the axial direction of the rotating shaft 31. A third mounting groove 2221 is formed in the second connecting plate 222. The second connecting plate 222 is stacked on the fixing frame 34. A fifth fastener passes through the third mounting groove 2221 and the fourth mounting hole 341 respectively to lock the second connecting plate 222 to the fixing frame 34. The arrangement of the first connecting plate 221, the second connecting plate 222, and the third connecting plate 223 enables the connection between the mounting platform 210 and the fixing frame 34 with different axial heights along the rotating shaft 31, and the connecting member 220 occupies little space.

[0052] On the other hand, this application also provides a disconnector opening / closing detection device, including a detection structure 2 and the aforementioned mounting structure 1. The mounting structure 1 is used to install the detection structure 2 onto the disconnector mechanism 3. Specifically, the detection structure 2 includes a transmitter 21 and a detection unit 22, and the mounting structure 1 includes a first mounting component 100 and a second mounting component 200. The transmitter 21 is mounted on the first mounting component 100, and the detection unit 22 is mounted on the second mounting component 200. The disconnector opening / closing detection device of this application, through the aforementioned mounting structure 1, allows the detection structure 2 to be installed securely into an existing disconnector mechanism 3.

[0053] Specifically, the transmitter 21 includes a magnet, and the detection unit 22 includes a magnetic field sensor. A stable magnetic field is generated around the magnet. When the state of the knife switch mechanism 3 changes, the detection unit 22, which corresponds to the position of the transmitter 21, can detect the magnetic field and thus determine the opening and closing state of the knife switch mechanism 3.

[0054] In addition, the detection structure 2 also includes a receiving unit 23, which is installed on the second mounting component 200. The receiving unit 23 is used to receive, process and output the status signal transmitted by the detection unit 22. Specifically, it feeds back the processed status signal to the controller of the entire knife switch mechanism 3 so as to control the knife switch mechanism 3 or its opening and closing state.
