Description

Technical Field

[0001] The invention belongs to the technical field of pole-mounted switches, and in particular relates to an auxiliary maintenance mechanism for pole-mounted switches. Background Art

[0002] Pole switches are a type of safety switch installed on utility poles to ensure the safety of electricity use. Their main function is to isolate the high voltage of the circuit. They have obvious differences in function, structure, application scenarios, etc., and each plays a unique role in the power system, jointly maintaining the safety and stable operation of the power grid. However, in order to ensure the safety of the power grid, it is necessary to regularly maintain and inspect the pole switches to avoid damage to the pole switches, which will lead to the inability to ensure the safety of the power grid.

[0003] Publication number: CN116031084A, discloses a pole switch that is easy to maintain. It includes a supporting bracket installed between the main pole and the auxiliary pole, and a pole switch is installed on the supporting bracket; the main pole is provided with a maintenance mechanism for flipping and lifting the supporting bracket; the supporting bracket includes a main mounting frame for installing a circuit breaker and a current transformer, and mounting brackets for installing a voltage transformer are provided on both sides of the main mounting frame; an intelligent feeder unit is installed on one side of the lower part of the main pole through a clamp; the auxiliary pole is provided with a support frame overlapped with the front end of the main mounting frame on the side close to the supporting bracket. The present invention can realize efficient and convenient flipping and lifting operations of the pole switch by organically combining the maintenance mechanism and the supporting bracket with the pole switch; thereby allowing the staff to complete the maintenance or parts replacement of the pole switch on the ground or at a lower place; while improving the maintenance efficiency, it also greatly reduces the safety risks of the staff.

[0004] However, there are some problems with the prior art: although the above-mentioned prior art can flip the pole switch and lower it, lowering the position of the pole switch, making it easier for staff to complete the inspection and maintenance of the pole switch on the ground or at a lower place, the above-mentioned technology still has the following problems: First, a special electric pole is required, which changes the original stable support of the electric pole, easily affecting the stable support of the pole switch by the electric pole, and the manufacturing cost of the special electric pole is high, and there are certain limitations. Secondly, the pole switch uses a pulley rope method to change the position of the pole switch. Although it is convenient to lift and lower the pole switch for convenient maintenance, the service life of the rope is limited, and the pole switch needs to be hoisted for a long time. This leads to the need to check the use of the rope during daily inspection and maintenance of the pole switch, which undoubtedly increases the workload of the staff and cannot meet the current situation. Therefore, we propose an auxiliary maintenance mechanism for the pole switch. Summary of the invention

The linkage component 902 is arranged between the docking fixing component 903 and the insulating switch component 901, and the docking fixing component 903 and the insulating switch component 901 are both connected to the linkage component 902 in a transmission manner. A docking gasket 18 is arranged at one end of the conductor 3. The docking fixing component 903 is arranged on one side of the pole body 1, and the docking gasket 18 is detachably connected to the upper surface of the insulating column 204 through the docking fixing component 903. The insulating switch component 901 is arranged on one side of the lifting plate 202, and both ends of one side of the pole-mounted circuit breaker 203 are provided with a power-on crank 6 for controlling the current. The insulating switch component 901 is movably connected to the power-on crank 6, and the power-on crank 6 is repeatedly rotated by the insulating switch component 901. Through the design that the docking fixing component 903 and the insulating switch component 901 are both transmission-connected with the linkage component 902, when the docking fixing component 903 cancels the extrusion of the docking gasket 18, the linkage component 902 can transmit the insulating switch component 901 to control the power-on crank 6 to rotate or repeatedly rotate to achieve the power-off operation. Therefore, through the linkage component 902, the preparation work before the maintenance of the pole switch can be quickly completed, thereby effectively improving the maintenance efficiency of the pole switch.

[0042] like Figures 1 to 16As shown, the anti-fall component 11 is designed to be arranged below the upper end of the lifting component 10. The upper end of the lifting component 10 serves as a fulcrum, and the wheel group is used to realize the lifting and lowering of the lifting plate 202. The upper end of the lifting component 10 serves as a fulcrum and is subjected to severe force. Therefore, the anti-fall component 11 is arranged below the upper end of the lifting component 10.

[0049] like Figures 1 to 16 As shown, through the arc-shaped design on one side of the docking column, when the fixed cover plate 9034 rotates around the driven gear 9032, the inner wall of the fixing hole can perfectly fit the outer side of the docking column, thereby achieving a more stable fixation of the docking gasket 18 on the docking pad plate 19.

[0050] By setting up the second synchronization mechanism 9035, the drive assembly 21 can cooperate with the second synchronization mechanism 9035 to simultaneously control the rotation of two groups of second linkage rods 9031 on the same side, so that the docking gasket 18 connected by multiple groups of wires 3 is separated from the docking pad 19, thereby improving the preparation work before the pole-mounted switch is lowered for maintenance.

[0051] Furthermore, the linkage component 902 includes a bevel gear linkage mechanism 9027 and a first synchronization mechanism 9023, the bevel gear linkage mechanism 9027 is transmission-connected with the second synchronization mechanism 9035, a mounting shell 9021 is fixedly mounted on one end of the upper surface of the sliding bearing plate 9014, the second synchronization mechanism 9035 is arranged inside the mounting shell 9021, and a first linkage rod 9022 is arranged between the bevel gear linkage mechanism 9027 and the first synchronization mechanism 9023, so that the bevel gear linkage mechanism 9027 is connected to the first synchronization mechanism 9035 through the first linkage rod 9022. 23 transmission connection, one end of the bottom of the first synchronization mechanism 9023 is transmission connected to a transmission housing 9024, the bottom of the transmission housing 9024 is hollow, a sliding groove is provided on the upper surface of the sliding bearing plate 9014, the lower end of the sliding seat 9015 is slidably installed inside the sliding groove, a pull rope 9016 is fixedly installed at the lower end of one side of the sliding seat 9015, a winding wheel 9025 is provided at the lower end of the transmission housing 9024, one end of the pull rope 9016 is wound around the outside of the winding wheel 9025, and the winding wheel 9025 is rotatably installed inside the sliding groove; a lower part of the sliding groove is provided inside the sliding groove. A reset groove is provided at the end, a positioning rod 9026 is fixedly installed at the bottom of the winding wheel 9025, one end of the positioning rod 9026 extends into the reset groove, a reset spring 7 is fixedly installed on the inner wall of the reset groove, and the reset spring 7 is fixedly connected to the positioning rod 9026; a groove 8 is provided inside the transmission housing 9024, and a push plate 13 is elastically connected inside the groove 8, and one end of the two sides of the push plate 13 is relatively inclined, a transmission rod 14 is fixedly installed in the middle of the upper surface of the winding wheel 9025, and a force plate 15 is fixedly installed on the outer side of the transmission rod 14, and the force plate 1 5 is arranged corresponding to the push plate 13, one end of the force plate 15 is rounded, one end of the positioning rod 9026 passes through the lower part of the reset groove to the bottom of the sliding bearing plate 9014, a convex point is fixedly installed on the lower end of the outer side of the positioning rod 9026, and a fixing plate 16 is rotatably connected to the upper surface of the convex point, and the fixing plate 16 is fixed to the convex point by bolts, and a first clamping joint 17 is fixedly installed on one side of the fixing plate 16, and a baffle plate 12 is fixedly installed on one end of the bottom of the sliding bearing plate 9014, and a clamping groove is opened on one side of the baffle plate 12, and the first clamping joint 17 is clamped in the inside of the clamping groove; like Figures 1 to 15 As shown, through the design that the force-bearing plate 15 and the pushing plate 13 are set correspondingly, the inclined side of the end of the pushing plate 13 contacts the force-bearing plate 15, and then the force-bearing plate 15 is pushed, and the winding wheel 9025 is driven to rotate through the transmission rod 14. At this moment, when the winding wheel 9025 rotates, it will reel in the pull rope 9016, so that the pull rope 9016 drives the sliding seat 9015 to slide, and the sliding seat 9015 cooperates with the connecting rod 9013, the base 9012 and the pull rod 9011 to realize the rotation of the powered crank 6 and perform the power-off operation.

[0052] By setting the baffle 12 and the design that the lower end of the positioning rod 9026 extends to the bottom of the sliding bearing plate 9014, when the winding wheel 9025 rotates, the positioning rod 9026 can be driven to rotate, and the positioning rod 9026 drives the protrusion to rotate. Then, after the protrusion rotates to a certain position, it will contact the baffle 12. At this time, the positioning rod 9026 cannot rotate, and the push plate 13 continues to rotate. The transmission rod 14 is not subjected to the thrust force for an instant, and the transmission rod 14 will rotate through the force of the reset spring 7. At this moment, the pull rod 9011 will be reset, and then continue to contact with the push plate 13, so that the pull rod 9011 can repeatedly pull the power crank 6 to release the stored energy inside the switch.

[0053] It is worth mentioning that the two power cranks 6 on the pole-mounted circuit breaker 203 correspond to the switch for releasing the energy stored inside the switch and the power-off switch respectively. To release the switch for storing energy inside the switch, the power crank 6 needs to be repeatedly rotated, while the power-off switch only needs to be rotated once. The positioning rod 9026 used for the position where the power crank 6 only needs to be rotated once, and the fixing plate 16 connected to the convex point extending from the positioning rod 9026 is rotated, and the fixing plate 16 is flipped to a vertical state and fixed at an angle by bolts. When the positioning rod 9026 drives the convex point to contact the baffle 12, the first clamping joint 17 is engaged in the clamping groove, and the positioning rod 9026 will be unable to rotate. Therefore, after the power crank 6 that only needs to be rotated once is rotated, the angle is fixed and it will not be rotated repeatedly.

[0054] It should be noted that the connection between the power crank 6 and the pole-mounted circuit breaker 203 is equipped with a torsion spring to achieve automatic rotation, and the power crank 6 can rotate on the pole-mounted circuit breaker 203, which is already a mature technology, so the present invention will not be elaborated here.

[0055] In summary, through the mutual cooperation of the baffle 12, the push plate 13, the force plate 15, the positioning rod 9026 and the reset spring 7, when the fixed cover plate 9034 is flipped open, the stored energy inside the pole-mounted circuit breaker 203 switch can be released and the power-off operation can be performed at the same time, so that the preparation work before the pole-mounted switch is lowered can be completed quickly, thereby improving the maintenance efficiency of the pole-mounted switch.

[0056] Furthermore, the lifting assembly 10 includes a positioning sleeve 101 and an automatic reel 105. The positioning sleeve 101 is fixedly sleeved on the upper end of the outer side of the pole body 1. A pulley 102 is rotatably connected to one side of the positioning sleeve 101. A steel rope 103 is wound around the outer side of the automatic reel 105. The steel rope 103 passes over the top of the pulley 102 and is fixedly connected to the lifting sleeve 5. A speed limiter 104 is arranged between the positioning sleeve 101 and the lifting sleeve 5. like Figures 1 to 16As shown, by the design of the speed limiter 104, the lifting speed of the lifting sleeve 5 can be controlled, thereby preventing the lifting sleeve 5 from falling instantly when the steel rope 103 breaks, causing damage to the pole switch.

[0057] Furthermore, the anti-fall assembly 11 includes a positioning ring 1101 and a plurality of extrusion plates 1102. The positioning ring 1101 is detachably sleeved on the outside of the pole body 1 by bolts. The plurality of extrusion plates 1102 are arranged in a circular shape with equal spacing, and the extrusion plates 1102 are rotatably connected to the positioning ring 1101. The lower end of one side of the extrusion plate 1102 is arranged in an arc shape corresponding to the pole body 1. The outer side of the positioning ring 1101 is provided with a plurality of stabilizing grooves, and the plurality of stabilizing grooves are arranged in a circular shape with equal spacing. A plurality of plug-in rods 1103 are fixedly installed at the bottom of the positioning ring 1101. The plug-in rods 1103 are arranged in a circular shape with equal spacing. 3 is slidably plugged into the stable groove, a rotating rod 1107 is fixedly installed on the upper surface of the extrusion plate 1102, and the rotating rod 1107 is rotatably connected to the bottom of the positioning ring 1101, and pressure rods 1105 are fixedly installed at both ends of the rotating rod 1107, and the opposite ends of the pressure rod 1105 and the plug-in rod 1103 are arranged to be inclined to fit each other, and the plug-in rod 1103 is slidably arranged in the stable groove with the rotating rod 1107 as the central axis, and multiple groups of extension slides 1106 are fixedly installed on the outer side of the positioning ring 1101, and the plug-in rod 1103 is slidably connected to the extension slides 1106; like Figures 1 to 16 As shown, by the design that the opposite ends of the compression rod 1105 and the connecting rod 1103 are arranged in an inclined manner to fit each other, when the steel rope 103 labor positioning sleeve 101 descends, the positioning sleeve 101 descends and drives the connecting rod 1103 to squeeze the compression rod 1105, and the compression rod 1105 rotates around the rotating rod 1107, and drives the extrusion plate 1102 to squeeze the pole body 1, thereby increasing the friction force and improving the stability of the positioning ring 1101 on the outside of the pole body 1, thereby effectively preventing the positioning sleeve 101 from falling off at the installation position and causing the switch on the pole to fall and be damaged.

[0058] Specifically, Fig.15 As shown, multiple groups of aluminum I-plates 1104 are arranged between the positioning sleeve 101 and the positioning ring 1101. When the positioning sleeve 101 descends, the aluminum I-plates 1104 serve as the first line of defense to prevent the positioning sleeve 101 from falling instantly and causing a large impact force on the positioning ring 1101, thereby affecting the means of increasing friction of the multiple groups of extrusion plates 1102. The middle part of the aluminum I-plates 1104 is in a bent state, which can buffer the pressure of the instantaneous descent of the positioning sleeve 101, thereby achieving stable increase of friction of the multiple groups of extrusion plates 1102, further improving the stability of the positioning ring 1101 after installation and the stability of the pole switch after maintenance after installation.

[0059] In summary, it should be noted that the first synchronization mechanism 9023 and the second synchronization mechanism 9035 in the present invention both adopt a transmission method of two sets of synchronization wheels and a synchronization belt to achieve the purpose of synchronous transmission. The transmission method of two sets of synchronization wheels and a synchronization belt to achieve the purpose of synchronous transmission has become an existing mature technical means. Therefore, the present invention will not be elaborated here.

[0060] In addition, the bevel gear linkage mechanism 9027 mentioned above adopts the method of two sets of bevel gears meshing with each other to realize reversing transmission, so that the second synchronization mechanism 9035 can drive the first linkage rod 9022 to rotate through the bevel gear linkage mechanism 9027. The method of two sets of bevel gears meshing with each other to realize reversing transmission is already a mature transmission technology means, so the present invention will not be elaborated here.
