[0032] Please see the attached Figure 1-4In one embodiment, the present invention provides an angle adjustment structure for an isolating switch porcelain bottle 122, which includes an isolating switch body 10 and an angle adjustment assembly 20. First of all, it should be noted that, unlike the prior art, in the process of repairing and replacing the porcelain bottle 122 and the main conductive assembly, the movement trajectory of the main knife will be affected by the starting angle. Different starting angles will result in different knife switch cutting contact points. In the case of a large angle deviation, the new main knife will not be able to open or close the switch normally. However, the torque required for angle adjustment is large, and it is inconvenient to operate manually, which is time-consuming and labor-intensive. The present application solves the above-mentioned defects in the prior art by providing an angle adjustment structure for the isolating switch porcelain bottle 122, as follows:
[0033] The isolating switch body 10 includes a support bracket 110 and two switch units 120 arranged opposite to each other along the length direction of the support bracket 110, each of the switch units 120 includes a bearing seat 121 and a porcelain bottle 122, the bottom end of the bearing seat 121 is fixed to the support bracket 110, the top end of the bearing seat 121 is rotatably arranged in the horizontal direction, and the top end of the bearing seat 121 is provided with a plurality of mounting holes spaced apart along the circumferential direction, each of the mounting holes is connected to a fastener 130, and the fastener 130 extends upward from the mounting hole; the angle adjustment component 2 0 includes a monopole connecting rod 210 and two crank arm plates 220, each of which includes a connecting end 221 and an adjustment end 222. The monopole connecting rod 210 is arranged to be telescopically adjustable at both ends along its own length direction. The two ends of the monopole connecting rod 210 are rotatably connected to the connecting ends 221 of the two crank arm plates 220, respectively. The adjustment end 222 is provided with an adjustment hole 2221 for the fastener 130 to pass through. The adjustment end 222 is sleeved on the fastener 130. The bottom end of the porcelain bottle 122 is arranged on the crank arm plate 220 and connected to the fastener 130.
[0034] Specifically, the angle adjustment structure of the isolating switch porcelain bottle 122 in the present application includes an isolating switch body 10 and an angle adjustment assembly 20. The isolating switch body 10 in the present application is mainly applied to the GW4 type double-column rotating outdoor high-voltage copper tube structure isolating switch, which includes but is not limited to a support bracket 110 and two switch units 120 arranged opposite to each other along the length direction of the support bracket 110. The support bracket 110 is used for installing the switch unit 120, and the two switch units 120 rotate towards / oppositely to achieve double-column opening / closing. Each of the switch units 120 includes a bearing seat 121 and a porcelain bottle 122. The bearing seat 121 is fixedly installed on the support bracket 110 by bolts, and is also convenient for disassembly and assembly by bolts. The top of the bearing seat 121 is in the form of a disc that can be rotated in the horizontal direction, so that the porcelain bottle 122 connected to the top of the bearing seat 121 can follow the rotation to achieve opening / closing. It is mainly connected by a fastener 130 that passes through the mounting hole from the bottom and is tightened to extend into the bottom of the porcelain bottle 122.
[0035] Among them, considering that when the main conductive assembly above the porcelain bottle 122 is replaced (not shown in the figure), the starting angle of the porcelain bottle 122 will be offset, resulting in a different starting angle, which will cause different cut-in contact points to affect the opening and closing problem. Therefore, it is necessary to adjust the starting angle of the porcelain bottle 122 through the angle adjustment component 20, which includes a single-pole connecting rod 210 and two crank arm plates 220. The single-pole connecting rod 210 is used to extend the force arm of the angle adjustment force point to achieve a labor-saving effect, and the two crank arm plates 220 are used to connect with the two bearing seats 121 respectively, so that one rod can be used for multiple purposes (that is, the angles of both ends can be adjusted in real time), and each of the crank arm plates 220 includes a connecting end 221 and an adjusting end 2 22. The connecting end 221 is used for rotatable connection with the monopole connecting rod 210, so that it can rotate along with the change of the adjustment direction when the adjustment angle is rotated, avoiding structural damage caused by rotation under a rigid connection. Preferably, a hinged connection method can be adopted, which is convenient to connect and simple to process; and the adjusting end 222 is used to connect with the fastener 130 passing through the top of the bearing seat 121, and the horizontal rotation thrust is applied to the fastener 130 by rotating the crank arm plate 220, thereby adjusting the rotation of the top of the bearing seat 121 until it returns to the starting angle. Therefore, an adjustment hole 2221 needs to be opened on the adjusting end 222 so that the adjusting end 222 can be sleeved on the fastener 130.
[0036] It can be understood that when installing the angle adjustment component 20, it is necessary to first remove the main conductive assembly above the porcelain bottle 122, then remove the porcelain bottle 122, and then connect the crank arm plate 220 to the top of the bearing seat 121, and then install the new porcelain bottle 122 on the crank arm plate 220 and fix it with the fastener 130. After the crank arm plates 220 on both sides are installed, the monopole connecting rod 210 can be installed, and you can prepare to adjust the initial angle.
[0037] As a preferred embodiment of the present invention, the crank arm plate 220 is Y-shaped, and the adjustment end 222 is recessed inward.
[0038] It should be noted that since the fasteners 130 at the top of the bearing seat 121 are arranged at intervals along the circumferential direction, setting the crank arm plate 220 in a Y shape allows its adjustment end 222 to be recessed inward to form a “>”-shaped end, which is used to be sleeved on the two fasteners 130, and its connecting end 221 (“—”-shaped end) is used to extend and be rotatably connected to the monopole connecting rod 210.
[0039] As a preferred embodiment of the present invention, the adjustment hole 2221 is a strip-shaped hole, the width of which is matched with the outer diameter of the fastener 130 , and a gap is left between the strip-shaped hole and the fastener 130 along its length direction.
[0040] It should be noted that the strip hole can reserve space when the fastener 130 passes through, which is convenient for installation according to different starting angles of the bearing seat 121, so that the crank arm plate 220 can be movable through the reserved gap after being mounted on the fastener 130, making installation more convenient and applicability better.
[0041] As a preferred embodiment of the present invention, the adjusting end 222 is arranged in an arc shape.
[0042] It is worth noting that since the top of the bearing seat 121 is usually disc-shaped, and the outer diameter of the bottom of the porcelain bottle 122 is usually also matched with the top of the disc-shaped bearing seat 121, the adjustment end 222 arranged between the porcelain bottle 122 and the bearing seat 121 is set in an arc shape to match the disc shape, so that it will not be exposed, reducing the size of the crank arm plate 220, and realizing the sophisticated and convenient installation of the component.
[0043] As a preferred embodiment of the present invention, the monopole connecting rod 210 includes a connecting rod 211 and two connecting members 212 arranged opposite to each other at the two ends of the connecting rod 211. The two ends of the connecting rod 211 have internal threads, and the first end of the connecting member 212 has an external thread matched with the internal thread, so that the first end of the connecting member 212 can be adjustably connected to the connecting rod 211, and the second end of the connecting member 212 is rotatably connected to the connecting end 221 of the crank arm plate 220.
[0044] It is worth noting that the connecting rod 211 is used to extend the force arm of the angle adjustment force point to save effort for the operator, and the connecting member 212 is used to connect the crank arm plate 220 and the connecting rod 211, wherein internal threads are provided at both ends of the connecting rod 211, and external threads are provided at the first end of the connecting member 212, so that the length of the entire single-pole connecting rod 210 can be adjusted by tightening and loosening the threads, thereby adapting to isolating switches of different specifications and models; and the second end of the connecting member 212 is used to be rotatably connected to the connecting end 221 of the crank arm plate 220, thereby achieving a rotatable effect when adjusting the angle.
[0045] Furthermore, there are two adjustment holes 2221 , and the two adjustment holes 2221 are respectively arranged on both ends of the adjustment end 222 .
[0046] It should be noted that since the crank arm plate 220 is Y-shaped, in order to facilitate the connection of the crank arm plate 220, the number of the adjustment holes 2221 is set to two corresponding to the structural form of the adjustment end 222, so that the two adjustment holes 2221 are respectively arranged at the two ends of the adjustment end 222 (i.e., the top two ends of the Y).
[0047] Furthermore, the length of the adjustment hole 2221 is 25 mm to 30 mm.
[0048] It should be understood that, since in a preferred embodiment, the adjustment hole 2221 is a bar-shaped hole, its length can be set to leave a gap between it and the fastener 130, thereby facilitating rotation adjustment. Therefore, preferably, the length of the adjustment hole 2221 can be set to 25mm to 30mm.
[0049] Furthermore, the fastener 130 includes a fastening screw 131 and a fastening nut 132 . The fastening screw 131 passes through the mounting hole from bottom to top and extends upward from the mounting hole. The fastening nut 132 is sleeved on the fastening screw 131 .
[0050] It should be noted that the combination of the fastening screw 131 and the fastening nut 132 is convenient for installation, and the extension length of the fastening screw 131 can be adjusted as needed, thereby facilitating the installation and connection of the top arm plate 220 and the monopole connecting rod 210.
[0051] Furthermore, the fastener 130 further includes a washer 133 , which is sleeved on the fastening screw 131 and disposed between the fastening nut 132 and the top end of the bearing seat 121 .
[0052] It can be understood that the washer 133 can increase the contact area between the fastening nut 132 and the top end of the bearing seat 121 to prevent the contact surface from being damaged, and at the same time can also enhance the fastening effect and play a role in preventing loosening.
[0053] 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.
