[0002] Insulated operating rods are a unified term for insulating tools specifically used in power systems. They can be used for live-line work, live-line inspection, and live-line maintenance. Insulated operating rods are insulating tools used for short-term operation of live equipment, such as connecting or disconnecting high-voltage disconnect switches and drop-out fuses. They are mainly used to ensure sufficient insulating safety distance for workers when performing power outage and restoration operations on distribution transformers and line switches.

[0003] However, during daily work, workers sometimes need to use a voltage detector to check for voltage before they can operate the insulating rod. The whole process requires switching between the voltage detector and the insulating rod, and workers need to lift and retract the rod multiple times, making the entire operation process cumbersome, prolonging the time workers spend in a live environment, and reducing the safety of workers during operation.

[0028] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0029] Example

[0030] like Figures 1 to 5 As shown, the novel insulated operating rod includes: an insulating rod 1, which includes: a telescopic part 11, a connecting cylinder 12 and a working head 13 connected in sequence;

[0031] The telescopic end of the telescopic part 11 is fixed to the connecting cylinder 12, and the telescopic end of the telescopic part 11 has a through hole, which is located inside the cavity of the connecting cylinder 12.

[0032] The axial section of the connecting cylinder 12 has a convex shape, and a buffer groove 121 is opened on the outer side of the connecting cylinder 12 at the position opposite to the through hole, and the buffer groove 121 is connected to the through hole.

[0033] Mounting base 4 is rotatably disposed on the outer side of the connecting cylinder 12, and the rotation point of the mounting base 4 and the center point of the buffer groove 121 are in the same horizontal plane. The mounting base 4 can rotate into the buffer groove 121. At the same time, the rotation surface of the mounting base 4 and the axis of the telescopic part 11 are coplanar, and the end face of the mounting base 4 is fixed with the extension plate 41.

[0034] Two sets of movable sleeves are symmetrically fixed along the width direction on the side of the extension plate 41 facing away from the mounting base 4, and torsion springs are fixed inside the two sets of movable sleeves.

[0035] The secondary pressing plate 5 has two sets of movable rods symmetrically fixed at the same end on both sides, and the two sets of movable rods are rotatably set in the movable sleeve by torsion springs. At the same time, the other end of the secondary pressing plate 5 is close to the connecting cylinder 12.

[0036] A fixing rope 2 is fixed at one end inside the telescopic part 11, and the other end of the fixing rope 2 passes through the through hole and the buffer groove 121 in sequence and is fixed to the surface of the mounting base 4.

[0037] The voltage detector 3 is fixed in the mounting slot opened in the mounting base 4.

[0038] Specifically, when a worker holds the insulated operating rod for live-line work, live-line inspection, or live-line maintenance, the voltage detector 3 is first pre-tested, and the intact voltage detector 3 is fixed in the mounting base 4. Then, the worker stretches the telescopic part 11 of the insulating rod 1, making the length of the insulating rod 1 longer. Under the action of the fixed rope 2 of fixed length, as the length of the insulating rod 1 increases, the mounting base 4 and the voltage detector 3 will rotate accordingly under the traction of the fixed rope 2, so that the angle of the voltage detector 3 can be flexibly adjusted.

[0039] The lighting unit is fixedly connected to the outer side of the connecting cylinder 12 near the working head 13. The notch of the lighting unit is directly opposite the mounting base 4, which can effectively prevent the lighting unit from interfering with the movement of the mounting base 4 and the secondary pressing plate 5. The lighting unit enables the insulated operating rod to have a lighting function, which makes it easier for workers to obtain a good field of vision in poor lighting conditions and improves the convenience of operation. At the same time, the temperature sensor fixed to the end face of the extension plate 41 is electrically connected to the display component fixed to the lower end of the telescopic part 11, which allows workers to obtain the temperature conditions of the corresponding area simultaneously when performing electrical testing, improving the accuracy of workers' judgment.

[0040] Meanwhile, when the mounting base 4 drives the electroscope 3 to rotate to the initial unfolding angle, the end face of the suspended end of the secondary pressing plate 5 will abut against the outer side of the connecting cylinder 12. As the telescopic part 11 of the insulating rod 1 further unfolds, the rotation angle of the mounting base 4 and the electroscope 3 will further increase, and the suspended end of the secondary pressing plate 5 will continue to abut against the outer side of the connecting cylinder 12 and the working head 13, and slide on their surfaces in sequence, so that the angle between the secondary pressing plate 5 and the extension plate 41 gradually increases. The torsion spring fixedly connected to the secondary pressing plate 5 will be further twisted due to the rotation. Therefore, under the action of the torsion spring, the secondary pressing plate 5 can apply a downward force to the mounting base 4 and the electroscope 3. The downward pressing force of the secondary pressing plate 5 and the traction force of the fixed rope 2 form a stable torque balance, effectively preventing the electroscope 3 from rotating due to external force or gravity.

[0041] Both ends of the sub-pressing plate 5 have an arc-shaped structure, and the torsion spring connected to the sub-pressing plate 5 by the movable rod has a preload under normal conditions.

[0042] Specifically, the arc-shaped structure of the end face of the sub-pressing plate 5 can reduce the probability of the sub-pressing plate 5 getting stuck when it comes into contact with and slides on the surface of the connecting cylinder 12 or the working head 13, thus ensuring the smooth movement of the sub-pressing plate 5.

[0043] The connection points of the outer side of the connecting cylinder 12 and the outer side of the working head 13 are located in the same plane.

[0044] Specifically, the connection between the connecting cylinder 12 and the working head 13 forms a plane, which in turn helps to enhance the smoothness of the transition when the sub-pressing plate 5 slides against the surface, ensuring that the sub-pressing plate 5, the voltage detector 3 and the mounting base 4 can move to their maximum range.

[0045] The size of the buffer groove 121 opened on the surface of the connecting cylinder 12 is adapted to the size of the outer side of the mounting base 4, and the lighting part fixed on the outer side of the connecting cylinder 12 has a C-shaped structure.

[0046] Specifically, the buffer groove 121 and the mounting base 4 are matched in size, which can not only ensure the normal rotation of the mounting base 4, but also help limit the rotation range of the mounting base 4. At the same time, the lighting unit allows the insulated operating rod to be used in dimly lit environments, ensuring the safety of workers.

[0047] The telescopic part 11 has a cylindrical through hole at the telescopic end, and the openings at both ends of the through hole are frustum-shaped. The fixing rope 2 is made of non-elastic PTFE fiber.

[0048] Specifically, the beveled structure with openings at both ends of the through hole can help reduce the friction of the fixing rope 2 when it moves, thus reducing the chance of damage to the fixing rope 2.

[0049] The temperature sensor is fixed to the end face of the extension plate 41 away from the mounting base 4, and a wiring groove is opened on the side of the extension plate 41.

[0050] Specifically, the temperature sensor allows workers to simultaneously acquire temperature data of the corresponding area during the electrical testing process, helping to improve the accuracy of the workers' judgment. At the same time, the display component electrically connected to the temperature sensor can use a brand model that is commonly available on the market and has equivalent performance.

[0051] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
