[0030] Please refer to the attached Figure 1-3In one embodiment of the present invention, an installation device for an electric operating mechanism of an isolating switch includes a fixed installation mechanism 10, a crank adjustment mechanism 20, a transmission mechanism 30 and a connecting mechanism 40. First of all, it should be noted that, unlike the various types of isolating switches in the prior art, the angle, installation position, installation size and interface size of the newly provided electric mechanism are different from those of the original manual mechanism shipped by the manufacturer. If the traditional installation method is followed, some mechanisms cannot meet the modification requirements. This application solves the above-mentioned defects in the prior art by providing an installation device for an electric operating mechanism of an isolating switch, as follows:

[0031] One end of the fixed installation mechanism 10 is used to be fixed on the isolating switch base 510, and the other end of the fixed installation mechanism 10 is provided with a circular channel 121 extending vertically. The crank arm adjustment mechanism 20 is connected to the circular channel 121 and is rotatably arranged. The bottom end of the crank arm adjustment mechanism 20 is used to be connected to the electric mechanism, and the two ends of the transmission mechanism 30 are respectively connected to the top of the crank arm adjustment mechanism 20 and the connecting mechanism 40 for transmission, and the connecting mechanism 40 is used to be connected to the vertical connecting rod 520.

[0032] Specifically, the installation device of the electric operating mechanism of the disconnector in the present application includes a fixed installation mechanism 10, a crank arm adjustment mechanism 20, a transmission mechanism 30 and a connecting mechanism 40. The fixed installation mechanism 10 is used for the installation of the crank arm adjustment mechanism 20, so that the new electric mechanism to be replaced (not shown in the figure) is connected under the crank arm adjustment mechanism 20 and then installed on the disconnector foundation 510 through the fixed installation mechanism 10. Therefore, the bottom end of the crank arm adjustment mechanism 20 is used for connecting the electric mechanism; the crank arm adjustment mechanism 20 is used to facilitate the adjustment of the connection between the electric mechanism and the vertical connecting rod 520, thereby solving the problem that the new electric mechanism cannot be directly connected to the vertical connecting rod 520 when directly installed in the traditional way. It is installed and connected in the circular channel 121 opened by the fixed installation mechanism 10; the connecting mechanism 40 is used to connect with the vertical connecting rod 520, and then the crank arm adjustment mechanism 20 and the connecting mechanism 40 are connected through the transmission mechanism 30, so that when the new electric mechanism rotates, the vertical connecting rod 520 can be driven to rotate, thereby realizing closing / opening the switch, so as to replace the manual operation mechanism box 530. Therefore, it can be understood that since the new electric mechanism is connected to the bottom end of the crank arm adjustment mechanism 20, in order to facilitate the normal rotation of the equipment, the crank arm adjustment mechanism 20 is connected through the circular channel 121 and is rotatably arranged itself, so that when the new electric mechanism rotates, the crank arm adjustment mechanism 20 can be driven to rotate.

[0033] As a preferred embodiment of the present invention, the crank arm adjustment mechanism 20 includes a crank arm 210 and a crank arm shaft 220, the crank arm shaft 220 is connected to the circular channel 121 and is rotatably arranged, the bottom end of the crank arm shaft 220 is used to connect to the electric mechanism, the first end of the crank arm 210 is connected to the top end of the crank arm shaft 220, the second end of the crank arm 210 is cantilevered outward from the first end, and one end of the transmission mechanism 30 is transmission-connected to the second end of the crank arm 210.

[0034] It should be noted that the crank arm 210 is used to connect with the transmission mechanism 30. By adjusting the crank arm 210, the extension space in the horizontal direction can be fully utilized, thereby changing the landing point of the connection between the electric mechanism and the vertical connecting rod 520, thereby solving the problem that the new electric mechanism may not be directly installed due to the difference in spacing distance when it is directly installed; the crank arm shaft 220 is used for the connection of the new electric mechanism to transmit the rotation effect. Therefore, the crank arm shaft 220 is connected to the circular channel 121 and is rotatably arranged, and the crank arm 210 is connected to the top of the crank arm shaft 220. When the electric mechanism drives the crank arm shaft 220 to rotate, it drives the crank arm 210 to rotate, and the transmission mechanism 30 connected to the crank arm 210 drives the vertical connecting rod 520 on the connecting mechanism 40 to rotate.

[0035] As a preferred embodiment of the present invention, the connecting mechanism 40 includes a connecting block 410 and a U-shaped bolt 420. The connecting block 410 is recessed on one side close to the vertical connecting rod 520 to form an arc-shaped groove 411 that matches the vertical connecting rod 520. The connecting block 410 is fixed to the vertical connecting rod 520 by cooperating with the U-shaped bolt 420. The side of the connecting block 410 that is away from the vertical connecting rod 520 is vertically protruded outward in the horizontal direction to form a connecting plate 412. The other end of the transmission mechanism 30 is transmission-connected to the connecting plate 412.

[0036] It should be noted that the connection method through the cooperation between the connecting block 410 and the U-bolt 420 is convenient for assembly and disassembly, and can adapt to vertical connecting rods 520 of different models and sizes, and the product adaptability is high. It is worth noting that the connecting block 410 is recessed on one side close to the vertical connecting rod 520 to form an arc-shaped groove 411, and the arc-shaped groove 411 matches the vertical connecting rod 520, so that it is more stable when connecting and fixing the vertical connecting rod 520, so as to avoid sliding when the connection between the connecting block 410 and the vertical connecting rod 520, thereby affecting the rotation effect and causing poor closing / opening effect; and the connecting plate 412 formed by the vertically protruding outward in the horizontal direction on the side of the connecting block 410 away from the vertical connecting rod 520 is used for transmission connection with the other end of the transmission mechanism 30.

[0037] As a preferred embodiment of the present invention, the transmission mechanism 30 includes a transmission link 310 , one end of the transmission link 310 is rotatably connected to the second end of the crank arm 210 , and the other end of the transmission link 310 is rotatably connected to the connecting plate 412 .

[0038] It is worth noting that the movement of the transmission connecting rod 310 is reliable and accurate, and can ensure the stability of the output angle. It is a transmission connection method commonly used in disconnector components.

[0039] As a preferred embodiment of the present invention, the transmission mechanism 30 also includes a first joint bearing 320, a first mounting hole is opened on the second end of the crank arm 210, the first joint bearing 320 is connected to the first mounting hole by bolts, and one end of the transmission connecting rod 310 is sleeved and connected to the first joint bearing 320.

[0040] It is worth noting that the spherical bearing is a spherical bearing, and the two ends of the transmission connecting rod 310 are usually connected by a pull ring, so that the rotation direction of any angle can be maintained after the spherical bearing is connected to the transmission, the transmission performance is better, the output angle is convenient to adjust, and the adaptability is better.

[0041] Furthermore, the transmission mechanism 30 also includes a second joint bearing 330 , a second mounting hole is opened on the connecting plate 412 , the second joint bearing 330 is connected to the second mounting hole by bolts, and the other end of the transmission connecting rod 310 is sleeved and connected to the second joint bearing 330 .

[0042] It should be noted that, consistent with the first joint bearing 320, the transmission connection method with the connecting plate 412 also adopts a joint bearing for transmission connection. The effect and structure of the second joint bearing 330 are the same as those of the first joint bearing 320, so they will not be described in detail here.

[0043] Furthermore, both ends of the transmission connecting rod 310 are telescopically adjustable along its own axial direction.

[0044] It should be understood that the pull rings at both ends of the transmission link 310 can be threadedly connected to achieve telescopic adjustment along the axial direction of the transmission link 310 to adapt to the spacing distance between different models of disconnector bases 510 and vertical links 520, thereby improving product adaptability.

[0045] Furthermore, the fixed installation mechanism 10 includes a connecting frame 110 and a mounting support 120 , wherein the connecting frame 110 is used to be fixed on the disconnector base 510 , the mounting support 120 is connected to the connecting frame 110 , and the mounting support 120 is provided with the circular channel 121 .

[0046] It should be noted that the connecting frame 110 is used to be connected to the bracket on the disconnector base 510 and can be installed by welding, and the mounting bracket 120 is used (through the circular channel 121 inside it) for the crank arm shaft 220 to pass through, so that the electric mechanism connected to the crank arm shaft 220 is installed on the disconnector base 510 through the mounting bracket.

[0047] Furthermore, a long hole 111 is formed on the connecting frame 110 , and the long hole 111 is extended in the horizontal direction. The mounting bracket 120 is connected to the connecting frame 110 adjustably by passing bolts through the long hole 111 .

[0048] It should be noted that the long hole 111 can facilitate the adjustment of the installation position of the mounting bracket 120 to fine-tune the spacing distance between the crank arm shaft 220 and the vertical connecting rod 520 on the mounting bracket 120, thereby further improving the adaptability of the product.

[0049] The present application also provides an isolating switch, including an isolating switch body 50, wherein the isolating switch body 50 includes an isolating switch base 510, a vertical connecting rod 520 and a manual operating mechanism box 530, wherein the isolating switch base 510 and the vertical connecting rod 520 are arranged at intervals, and the bottom end of the vertical connecting rod 520 is rotatably connected to the manual operating mechanism box 530, and further includes the isolating switch electric operating mechanism installation device as described above, wherein the fixed installation mechanism 10 of the isolating switch electric operating mechanism installation device is fixed on the isolating switch base 510, and the connecting mechanism 40 of the isolating switch electric operating mechanism installation device is connected to the vertical connecting rod 520.

[0050] It is understandable that the isolating switch body 50 includes but is not limited to the isolating switch base 510, the vertical connecting rod 520 and the manual operating mechanism box 530. The manual operating mechanism box 530 can still be manually closed / opened when the new electric mechanism fails and is replaced and maintained without affecting the use.

[0051] It is worth mentioning that, when installing and using, after all the components are installed, it is first necessary to adjust the length of the transmission connecting rod 310 and the initial angle, and drive the electric mechanism to close the switch. The electric mechanism drives the crank arm shaft 220 to rotate and drive the transmission connecting rod 310 to rotate. The transmission connecting rod 310 then drives and drives the vertical connecting rod 520 fixedly connected by the connecting block 410 and the U-bolt 420 to rotate. The vertical connecting rod 520 rotates to achieve the closing of the top support insulator switch. After the closing of the electric mechanism stops, if the support insulator switch of the disconnector is also in the closed position, it can be confirmed that the device is installed in place, the initial angle is adjusted in place, and the electric mechanism can be put into use normally; conversely, the principle of opening detection is similar to that of closing.

[0052] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
