Description

Technical Field

[0001] This application relates to the field of disconnector technology, specifically to an adjustable disconnector base. Background Technology

[0002] Disconnecting switches, generally referring to high-voltage disconnecting switches, are those with a rated voltage of 1kV and above. They are the most commonly used electrical appliances in high-voltage switchgear. Disconnecting switches are used at various voltage levels to change circuit connections or isolate lines or equipment from the power supply. They do not have interrupting current capability; the line must be disconnected using other equipment before operation.

[0003] Chinese patent document CN220041695U discloses a disconnecting switch, specifically including a base, an inlet plate, contacts, a limiting rod, and an outlet plate. The base has a stationary insulator and a moving insulator. The stationary insulator is fixedly installed, while the moving insulator is rotatably connected to the base. The inlet plate is mounted on the stationary insulator. The contacts include a contact base and multiple contact fingers. The contact base is located at one end of the inlet plate, and the multiple contact fingers are positioned opposite each other on the contact base to form a locking mechanism. The limiting rod is located on the inlet plate and extends along the length of the contact fingers. This patent ensures the accuracy of the contact position between the outlet plate and the contact fingers through the setting of the limiting rod, thereby ensuring safe power supply to the circuit.

[0004] However, in the aforementioned patent, the installation position between the base and the insulator is relatively fixed. When it is necessary to adjust the installation height of the insulator, only different models of bases can be replaced, which is difficult to operate and has high replacement costs. If shims or other components that can achieve height adjustment are set between the insulator and the base, the overall stability will be reduced. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this application provides an adjustable disconnector base.

[0006] This application adopts the following technical solution: an adjustable disconnector base, including a pair of upright plates and a movable plate and a limiting plate disposed between the pair of upright plates. The two ends of the limiting plate are respectively and correspondingly connected to the pair of upright plates. The limiting plate is provided with a light rod and a lead rod. The light rod passes through the movable plate and is slidably connected to the movable plate. The lead rod passes through the movable plate and is threadedly connected to the movable plate.

[0007] The top of the movable plate is provided with a connecting unit, which includes a base plate, a bearing seat and a rotating plate. The base plate is detachably provided on the top of the movable plate. The bottom of the bearing seat is connected to the base plate. The rotating plate is provided on the top of the bearing seat.

[0010] Optionally, the movable plate slides among a plurality of countersunk bolts, and the movable plate and the countersunk bolts do not interfere with each other in the vertical direction.

[0021] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] like Figure 1-4 As shown, the adjustable disconnector base includes a pair of upright plates 1, a movable plate 2 and a limiting plate 3 disposed between the pair of upright plates 1. The two ends of the limiting plate 3 are respectively and correspondingly connected to the pair of upright plates 1. The limiting plate 3 is provided with a smooth rod 4 and a lead rod 5. The smooth rod 4 passes through the movable plate 2 and is slidably connected to the movable plate 2. The lead rod 5 passes through the movable plate 2 and is threadedly connected to the movable plate 2. The top of the movable plate 2 is provided with a connecting unit 6. The connecting unit 6 includes a base plate 61, a bearing seat 62 and a rotating plate 63. The base plate 61 is detachably disposed on the top of the movable plate 2. The bottom of the bearing seat 62 is connected to the base plate 61. The rotating plate 63 is disposed on the top of the bearing seat 62. The top of the rotating plate 63 is provided with a plug sleeve 64 for inserting an insulator.

[0023] After the insulator is inserted into the sleeve 64, the rotating plate 63, sleeve 64, and insulator can reliably rotate when the disconnecting switch is opened and closed, since the rotating plate 63 is mounted on the bearing seat 62. When it is necessary to adjust the height of the insulator, the lead screw 5 can be rotated. Since the lead screw 5 is connected to the movable plate 2 by a thread, and under the limiting action of the smooth rod 4, the movable plate 2 cannot rotate, but can only move up and down along the axial direction of the lead screw 5. This realizes the up and down sliding of the movable plate 2 between a pair of upright plates 1, thereby realizing the adjustment of the height of the connecting unit 6. The operation is simple, there is no need to replace the entire base, and the connecting unit 6 can still maintain a reliable connection during the adjustment process.

[0024] The bearing housing 62 is fixedly connected to the base plate 61. The rotating plate 63 can rotate around the axis of the bearing housing 62. This ensures that the bearing housing 62 is in a stable installation state, allowing the rotating plate 63 to rotate smoothly, thereby ensuring that the disconnecting switch can reliably perform opening and closing operations.

[0025] Each upright plate 1 has a sliding plate 7 on its inner wall. The sliding plate 7 is connected to the upright plate 1 by several countersunk bolts 70. The end of the movable plate 2 is in contact with the sliding plate 7, and the surface roughness of the sliding plate 7 is less than that of the upright plate 1. The movable plate 2 slides between the countersunk bolts 70, and the movable plate 2 and the countersunk bolts 70 do not interfere with each other in the vertical direction. A pair of sliding plates 7 form a clamping effect on the movable plate 2, and because the surface roughness of the sliding plates 7 is lower, the movable plate 2 can slide more smoothly, thereby facilitating the quick and accurate height adjustment of the connecting unit 6. Furthermore, the sliding plates 7 are fixed by the countersunk bolts 70, and the movable plate 2 and the countersunk bolts 70 do not interfere with each other, improving the stability of the movement of the movable plate 2.

[0026] The movable plate 2 has a through hole 21 and a threaded hole 22. One end of the smooth rod 4 is connected to the top of the limiting plate 3, and the other end of the smooth rod 4 passes through the through hole 21 and is flush with the top of the upright plate 1. The inner wall of the through hole 21 is in contact with the outer wall of the smooth rod 4. The limiting plate 3 has a sliding sleeve 30. One end of the lead screw 5 is located below the limiting plate 3, and the other end of the lead screw 5 passes through the sliding sleeve 30 and the threaded hole 22 and is flush with the top of the upright plate 1. The inner wall of the sliding sleeve 30 is in contact with the outer wall of the lead screw 5, and the lead screw 5 is connected to the threaded hole 22 by a thread. A spring 40 is fitted on the smooth rod 4. The spring 40 is located between the movable plate 2 and the limiting plate 3. When the spring 40 is in a fully compressed state, the bottom of the movable plate 2 is in contact with the top of the sliding sleeve 30.

[0027] The engagement of the smooth rod 4 with the through hole 21 does not affect the vertical movement of the movable plate 2, while the spring 40 remains compressed. This ensures that the spring force of the spring 40 provides support for the movable plate 2, preventing it from shifting after the height adjustment is complete, thus reliably supporting the connecting unit 6. The fully compressed length of the spring 40 matches the length of the sliding sleeve 30 above the limiting plate 3, allowing both the spring 40 and the sliding sleeve 30 to simultaneously provide support for the movable plate 2 when it is adjusted to its lowest position.

[0028] The lead screw 5 has an adjustment knob 50 at one end located below the limiting plate 3, and the bottom of the adjustment knob 50 has an internal hexagonal hole 500. When it is necessary to rotate the lead screw 5 to adjust the height of the movable plate 2, a hexagonal wrench can be inserted into the internal hexagonal hole 500 to quickly and effortlessly rotate the lead screw 5.

[0029] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
