Description

Technical Field

[0001] This invention relates to the field of insulating rod technology, and more particularly to an insulating rod that is easy to insert into the pull-open rod hole of a post-mounted disconnect switch. Background Technology

[0002] A pole-mounted disconnect switch is a special type of safety switch primarily used on utility poles to ensure electrical safety. Generally, pole-mounted switches are installed on utility poles, and their main function is to isolate high-voltage circuits; they are a typical outdoor type of disconnect switch. A pole-mounted disconnect switch includes a pull-opening rod, which is rotated to open or close the switch. When the existing pole-mounted disconnect switch is in the closed state, the pull-opening rod extends horizontally. An extension plate is provided on the upper side of one end of the pull-opening rod, and a pull-opening rod hole is located on the upper side of the hole. To open the switch using an insulating rod, the insert rod on the insulating rod needs to be inserted into the pull-opening rod hole. Then, pushing the insulating rod upwards pushes the unlocking mechanism upwards, unlocking the pull-opening rod. Continuing to push the pull-opening rod upwards and rotating it further opens the switch.

[0003] Because the pole-mounted disconnect switch is high above the ground, and the distance between the pull rod hole and the ground personnel is far, it is difficult to see clearly. It is also difficult to align the insertion rod with the pull rod hole and insert it. It often takes many attempts to insert the pull rod hole, resulting in low opening efficiency of the existing insulating rod. Summary of the Invention

[0004] To address the shortcomings of existing insulating rods with low opening efficiency, this invention proposes an insulating rod with high opening efficiency that is easy to insert into the pull-close rod hole of the on-pole disconnector switch.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An insulating rod for easy insertion into the pull-opening rod hole of a post-mounted disconnect switch includes a rod body and a connector at the upper end of the rod body. The connector includes a main body and a rotating shaft rotatably connected to the main body. A first limiting protrusion is fixedly connected to the end of the rotating shaft away from the main body. A rotating rod is fixedly connected to the rotating shaft and is positioned between the first limiting protrusion and the main body. The rotating rod has an insert for cooperating with the pull-opening rod. The insert passes through the rotating rod and is slidably connected to it. A clearance groove is provided on one side of the main body to avoid the insert. A magnet is provided at the bottom of the clearance groove. One end of the insert abuts against the magnet, and the other end of the insert is flush with the side of the rotating rod away from the main body. A first spring is provided in the clearance groove. The rotating rod and the insert are connected by the first spring. The insulating rod for easy insertion into the pull-opening rod hole of a post-mounted disconnect switch also includes a locking mechanism for locking the rotating shaft and a driving device for driving the rotating shaft to rotate.

[0007] Furthermore, the pull rod extends horizontally, and an extension plate is provided on the upper side of one end of the pull rod, with a pull rod hole provided on the extension plate.

[0008] The above-described configuration allows the insertion rod to be quickly inserted into the pull rod hole for opening the circuit breaker. Specifically, in the existing pole-mounted disconnect switch, when in the closed state, the pull rod extends horizontally. An extension plate is provided on the upper side of one end of the pull rod, and a pull rod hole is provided on the extension plate. An unlocking mechanism is provided on the upper side of the pull rod hole. When using this application, the main body is first placed against the pull rod, and the rotating shaft is placed against the pull rod. At this time, the pull rod is located between the first limiting protrusion and the rotating rod. The first limiting protrusion can prevent the pull rod from sliding out from the end of the rotating shaft. Because the pull rod is relatively long, it is easy for ground personnel to see clearly and place the rotating shaft against the pull rod. Ground personnel hold the lower end of the pole and then drive the rotating shaft along the pole towards the extension plate until the rotating shaft and the extension plate abut. Under the action of the drive device, the rotating shaft drives the rotating rod to rotate around the axis of the rotating shaft. During this process, the rotating rod drives the insertion rod to move, and the clearance groove is used to avoid the insertion rod. The magnet and the main body are fixedly connected, so when the insertion rod moves with the rotating rod, the insertion rod gradually moves away from the magnet, and the attraction between the insertion rod and the magnet becomes weaker and weaker. The first spring applies a force to the insertion rod towards the pulling rod, that is, the force of the first spring on the insertion rod is opposite to the force of the magnet on the insertion rod. Therefore, when the insertion rod... When the force between the rod and the magnet is reduced to a certain level, the rod moves towards the closing rod under the action of the first spring and comes into contact with the closing rod. As the drive device continues to drive the rotating rod to rotate, the rod moves closer to the closing rod hole. When the rod moves to the closing rod hole, under the action of the first spring, the rod moves away from the main body and inserts into the closing rod hole. At this time, the rod has left the main body from the clearance groove. The locking mechanism locks the rotating shaft, thereby fixing the relative positions of the rotating rod, the rod, and the rod body. At this time, the unlocking mechanism can be pushed upward to unlock the closing rod. Then, the rod body can be pushed upward and the closing rod rotated to open the gate.

[0009] Furthermore, a first channel is provided inside the rod body, extending along the extension direction of the rod body and penetrating to the upper end of the rod body. A second channel is provided inside the main body, and the second channel communicates with the first channel. The driving device includes a rotatable reel connected inside the main body and a first pull line wound on the reel. A handle is rotatably connected to the rod body, and a transmission rod is provided at the lower end of the handle. A sliding block is slidably connected to the rod body and is located below the handle. One end of the transmission rod is rotatably connected to the handle, and the other end of the transmission rod is rotatably connected to the sliding block. A first groove communicating with the first channel is provided on the rod body, and a pull line block is slidably connected in the first groove. The end of the first pull line away from the reel is connected to the pull line block.

[0010] The above setup enables the shaft to rotate. Specifically, when the handle is gripped and rotated, the handle approaches the rod and drives the sliding block downwards via the transmission rod. The sliding block pulls the first pull line downwards via the pull line block, releasing the first pull line from the spool and causing the spool to rotate, thus achieving the rotation of the shaft.

[0011] Furthermore, a second limiting protrusion is provided circumferentially at the end of the insertion rod away from the magnet, and a groove is provided on the rotating rod, with the second limiting protrusion located within the groove.

[0012] With the above configuration, when the insert rod is inserted into the pull rod hole, the second limiting protrusion can be locked at the edge of the pull rod hole when the rod body is pushed upward, thereby preventing the insert rod from separating from the pull rod hole.

[0013] Furthermore, a second slide groove is provided inside the main body. The second slide groove is located on the side of the rotating shaft away from the first limiting protrusion. A slot is provided on the side of the rotating shaft away from the first limiting protrusion. A third channel is provided on the rotating rod, and a fourth channel is provided on the rotating shaft. The third channel and the fourth channel are connected. The locking mechanism includes a locking pin rotatably connected in the second slide groove. The bottom of the second slide groove is connected to the locking pin by a second spring. A buffer space is provided between the end of the locking pin near the first limiting protrusion and the opening of the second slide groove. The locking pin and the slot are adapted to each other. The locking pin is connected to the insertion rod by a second pull wire. The second pull wire passes through the third channel and the fourth channel.

[0014] The above setup allows for locking of the rotating shaft. Specifically, when the rotating rod rotates and reduces the attraction between the magnet and the insert rod, the insert rod abuts against the pull rod under the action of the first spring. Under the action of the second pull line, the locking pin moves towards the slot, reducing the buffer space. At this point, the locking pin has not yet been inserted into the slot, meaning the rotating shaft can continue to drive the rotating rod to rotate, causing the insert rod to continue moving closer to the pull rod under the action of the first pull line. When the insert rod is inserted into the pull rod hole under the action of the first spring, the locking pin is inserted into the slot under the action of the second pull line. Since the locking pin and the second slide cannot rotate relative to each other, the roller and the rotating shaft cannot continue to rotate, meaning the rotating shaft is locked. It should be noted that when the insert rod is inserted into the pull rod hole, if the locking pin and the slot are not aligned, the locking pin will be pressed against the end of the rotating shaft under the action of the second pull line. At this time, the handle continues to be pressed, the first pull line continues to move downward and drive the rotating shaft to rotate. When the locking pin and the slot are aligned, the locking pin is inserted into the slot under the action of the second pull line.

[0015] Furthermore, the end of the third channel away from the fourth channel extends to the second limiting protrusion, and the second pull line connects to the second limiting protrusion.

[0016] Furthermore, the second limiting protrusion and the insert rod are integrally formed.

[0017] Furthermore, the cross-section of the locking pin is square. Attached Figure Description

[0029] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0030] See Figures 1 to 11An insulating rod for easy insertion into the pull-opening rod hole of a post-mounted disconnector switch includes a rod body 11 and a connector 12 disposed at the upper end of the rod body 11. The connector 12 includes a main body 121 and a rotating shaft 122 rotatably connected to the main body 121. A first limiting protrusion 1221 is fixedly connected to the end of the rotating shaft 122 away from the main body 121. A rotating rod 1222 is fixedly connected to the rotating shaft 122. The rotating rod 1222 is disposed between the first limiting protrusion 1221 and the main body 121. The rotating rod 1222 is provided with an insert 12221 for cooperating with the pull-opening rod 21. The insert 12221 passes through the rotating rod 1222 and slides with the rotating rod 1222. Next, a clearance groove 1211 is provided on one side of the main body 121 to avoid the insertion rod 12221. A magnet 1212 is provided at the bottom of the clearance groove 1211. One end of the insertion rod 12221 abuts against the magnet 1212, and the other end of the insertion rod 12221 is flush with the side of the rotating rod 1222 away from the main body 121. A first spring 1213 is provided in the clearance groove 1211. The rotating rod 1222 and the insertion rod 12221 are connected by the first spring 1213. The insulating rod that is easy to guide into the pull rod hole of the disconnect switch on the column also includes a locking mechanism 13 for locking the rotating shaft 122 and a driving device 14 for driving the rotating shaft 122 to rotate.

[0031] As one implementation, the pull rod 21 extends horizontally, and an extension plate 23 is provided on the upper side of one end of the pull rod 21, and a pull rod hole 22 is provided on the extension plate 23.

[0032] The above configuration allows the insertion rod 12221 to be quickly inserted into the pull-opening rod hole 22 and the gate opening operation to be performed. For details, see [link to details]. Figure 4 When the existing pole-mounted disconnect switch is in the closed state, the pull rod 21 extends horizontally. An extension plate 23 is provided on the upper side of one end of the pull rod, and a pull rod hole 22 is provided on the extension plate 23. An unlocking mechanism 24 is provided on the upper side of the pull rod hole 22. When using this application, the main body 121 is first placed against the pull rod 21, so that the rotating shaft 122 abuts against the pull rod 21. See [reference needed]. Figure 6 and Figure 5 At this time, the pulling rod 21 is located between the first limiting protrusion 1221 and the rotating rod 1222. The first limiting protrusion 1221 prevents the pulling rod 21 from sliding out from the end of the rotating shaft 122. Because the pulling rod 21 is relatively long, it is easy for ground personnel to see and abut the rotating shaft 122 against the pulling rod 21. The ground personnel hold the lower end of the rod body 11 and then drive the rotating shaft 122 along the rod body 11 towards the extension plate 23 until the rotating shaft 122 and the extension plate 23 abut against each other. See [link to relevant documentation]. Figure 7 Under the action of the drive device 14, the rotating shaft 122 drives the rotating rod 1222 to rotate around the axis of the rotating shaft 122. See [link / reference] Figure 8During this process, the rotating rod 1222 drives the insertion rod 12221 to move, while the clearance groove 1211 is used to avoid the insertion rod 12221. The magnet 1212 is fixedly connected to the main body 121, so when the insertion rod 12221 moves with the rotating rod 1222, the insertion rod 12221 gradually moves away from the magnet 1212. (See [reference]) Figure 8 As the attractive force between the insertion rod 12221 and the magnet 1212 decreases, the first spring 1213 applies a force to the insertion rod 12221 towards the pulling rod 21. That is, the force exerted by the first spring 1213 on the insertion rod 12221 is opposite in direction to the force exerted by the magnet 1212 on the insertion rod 12221. Therefore, when the force between the insertion rod 12221 and the magnet 1212 decreases to a certain level, the insertion rod 12221 moves towards the pulling rod 21 under the action of the first spring 1213 and comes into contact with the pulling rod 21. (See [link]). Figure 9 As the driving device 14 continues to drive the rotating rod 1222 to rotate, the insertion rod 12221 moves closer to the pull rod hole 22. When the insertion rod 12221 moves to the pull rod hole 22, under the action of the first spring 1213, the insertion rod 12221 moves away from the main body 121 and inserts into the pull rod hole 22. (See below) Figure 10 and Figure 11 At this point, the insertion rod 12221 has left the main body 121 from the clearance groove 1211, and the locking mechanism 13 locks the rotating shaft 122, thereby fixing the relative positions of the rotating rod 1222, the insertion rod 12221 and the rod body 11. At this time, the unlocking mechanism 24 can be pushed upward to unlock the pulling rod 21, and then the rod body 11 can be pushed upward and the pulling rod 21 can be rotated to open the gate.

[0033] As one implementation, a first channel 111 is provided inside the rod 11, extending along the extension direction of the rod 11 and penetrating to the upper end of the rod 11. A second channel 1214 is provided inside the main body 121, communicating with the first channel 111. The driving device 14 includes a reel 141 rotatably connected inside the main body 121 and a first pull wire 142 wound on the reel 141. A handle 143 is rotatably connected to the rod 11. A transmission rod 144 is provided at the lower end of the 3. A sliding block 145 is slidably connected to the rod body 11. The sliding block 145 is located on the lower side of the handle 143. One end of the transmission rod 144 is rotatably connected to the handle 143, and the other end of the transmission rod 144 is rotatably connected to the sliding block 145. A first groove 112 communicating with the first channel 111 is provided on the rod body 11. A pull wire block 146 is slidably connected in the first groove 112. The end of the first pull wire 142 away from the wire wheel 141 is connected to the pull wire block 146.

[0034] The above settings enable the rotation of the shaft 122. Specifically, when the handle 143 is held and rotated, the handle 143 approaches the rod 11 and drives the sliding block 145 downward through the transmission rod 144. The sliding block 145 pulls the first pull line 142 downward through the pull line block 146. The first pull line 142 is released from the spool 141 and drives the spool 141 to rotate, thereby enabling the rotation of the shaft 122.

[0035] As one implementation, the end of the insertion rod 12221 away from the magnet 1212 is provided with a second limiting protrusion 12222 in the circumferential direction, and the rotating rod 1222 is provided with a groove 12223, with the second limiting protrusion 12222 disposed in the groove 12223.

[0036] With the above settings, when the insertion rod 12221 is inserted into the pull rod hole 22, the second limiting protrusion 12222 can be locked at the edge of the pull rod hole 22 when the rod body 11 is pushed upward, thereby preventing the insertion rod 12221 from separating from the pull rod hole 22.

[0037] As one implementation, a second slide groove 1215 is provided inside the main body 121. The second slide groove 1215 is located on the side of the rotating shaft 122 away from the first limiting protrusion 1221. A slot 1223 is provided on the side of the rotating shaft 122 away from the first limiting protrusion 1221. A third channel 12224 is provided on the rotating rod 1222, and a fourth channel 12225 is provided on the rotating shaft 1222. The third channel 12224 and the fourth channel 12225 are connected. The locking mechanism 13 includes a rotating link. A locking pin 131 is connected in the second slide groove 1215. The bottom of the second slide groove 1215 is connected to the locking pin 131 by the second spring 132. A buffer space 133 is provided between the end of the locking pin 131 near the first limiting protrusion 1221 and the opening of the second slide groove 1215. The locking pin 131 and the slot 1223 are adapted to each other. The locking pin 131 is connected to the insertion rod 12221 by the second pull wire 134. The second pull wire 134 passes through the third channel 12224 and the fourth channel 12225.

[0038] With the above settings, the rotating shaft 122 can be locked. Specifically, when the rotating rod 1222 rotates and reduces the attraction between the magnet 1212 and the insertion rod 12221, the insertion rod 12221 abuts against the pulling rod 21 under the action of the first spring 1213. See [link to relevant documentation]. Figure 9 Under the action of the second pull wire 134, the locking pin 131 moves towards the slot 1223, and the buffer space 133 shrinks. (See below) Figure 9At this point, the locking pin 131 has not yet been inserted into the slot 1223, meaning the rotating shaft 122 can continue to drive the rotating rod 1222 to rotate, thus causing the insertion rod 12221 to continue moving closer to the pulling rod 21 under the action of the first pull wire 142. Once the insertion rod 12221 is inserted into the pulling rod hole 22 under the action of the first spring 1213, the locking pin 131 is inserted into the slot 1223 under the action of the second pull wire 134. (See below) Figure 11 Since the locking pin 131 and the second slide groove 1215 cannot rotate relative to each other, the roller and the rotating shaft 122 cannot continue to rotate, that is, the rotating shaft 122 is locked. Specifically, when the insertion rod 12221 is inserted into the pull rod hole 22, the locking pin 131 and the slot 1223 are not aligned. The locking pin 131 will be pressed against the end of the rotating shaft 122 under the action of the second pull line 134. At this time, the handle 143 continues to be pressed, and the first pull line 142 continues to move downward and drive the rotating shaft 122 to rotate. When the locking pin 131 and the slot 1223 are aligned, the locking pin 131 is inserted into the slot 1223 under the action of the second pull line 134.

[0039] In one implementation, the end of the third channel 12224 away from the fourth channel 12225 extends to the second limiting protrusion 12222, and the second pull wire 134 is connected to the second limiting protrusion 12222.

[0040] As one implementation method, the second limiting protrusion 12222 and the insertion rod 12221 are integrally formed structures.

[0041] As one implementation method, the cross-section of the locking pin 131 is square.

[0042] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
