Description

Technical Field

[0001] The invention relates to the technical field of power supply operation and maintenance tools, and in particular to a hook-type insulating operating rod. Background Art

[0002] The insulating operating rod is a common tool for operating switch-type equipment such as pole switches or drop-out fuses in the distribution network. The currently common insulating operating rod can be composed of a cascaded insulating rod body and an operating head fixed at the upper end of the rod body. During use, the operation and maintenance staff lifts the insulating operating rod, and connects the pull ring socket for the pull ring on the operating head with the pull ring hole of the operating pull ring of the pole switch or drop-out fuse to perform the switch operation. The problems are: first, since the operating pull ring of the pole switch or drop-out fuse is set at a high position and the pull ring hole of the operating pull ring is small, it is difficult for the operation and maintenance staff to see the pull ring hole clearly at night or in insufficient light, making it very difficult to connect the rod head of the insulating operating rod with the operating pull ring of the switch-type equipment. To solve this problem, the traditional practice is that one person uses a flashlight or other lighting device to illuminate, and the other person holds the insulating operating rod to operate The problem is that it requires two workers to work together to implement it, which wastes manpower; secondly, the pull ring sleeve connector of the existing insulating operating rod of this type is usually a single rod body member or a hook-shaped member fixedly set on the operating head. Since the rod body of the insulating operating rod is long and the pull ring hole is small, and the operating head has a considerable weight, the operating head is easy to shake when the operation and maintenance staff lifts the insulating operating rod to connect the pull ring sleeve connector on the operating head with the pull ring hole of the pull ring. The fixed rod-shaped or hook-shaped pull ring sleeve connector on the operating head is easy to interfere with the surrounding of the pull ring hole, making the sleeve connection more difficult. It often takes repeated attempts to insert the pull ring sleeve connector into the pull ring hole of the operating pull ring, which has low operation efficiency and requires high operating skills of the operator.

[0003] In order to solve the problem that two people need to work together at night or when the light is insufficient in the traditional practice, an insulating operating rod with auxiliary lighting came into being. For example, the Chinese patent document with publication number CN205282203U discloses a luminous insulating rod, which provides lighting by fixing the lighting device on the upper end of the operating rod with an elastic rubber ring. Another example is the Chinese patent document with publication number CN208922923U discloses a 10kV insulating operating rod with night lighting function, which provides auxiliary lighting by setting an LED lamp in a movable seat, and adjusting the position of the LED lamp by a sliding and rotating device. Although the above two operating rods can solve the problem that two people need to work together at night or when the light is insufficient in the traditional practice, both of them have the problem of unconcentrated light beams and serious light scattering of the light source, which affects the lighting effect. In addition, the technical solutions of both adopt the single rod body or hook-shaped member commonly used in the prior art as the pull ring sleeve, so the second technical problem mentioned above still exists. Therefore, it is necessary to further improve the existing insulating operating rod (rod). Summary of the invention

[0047] When the pull ring hole of the pole switch or drop-out fuse is not clearly visible at night or during the day when the light is insufficient, the operation and maintenance staff will pull out the two LED lamp mounting seats 33 from the lamp row accommodating holes 31-1 of the third rod body 31 until the two LED lamp mounting seats 33 are opened to a suitable angle according to the different operation objects, and then turn on the lighting switch 55 to light up the two groups of LED lamp groups 57; under the high-brightness direct light beam illumination from the intersection of the two groups of LED lamp groups 57, the operation and maintenance staff can clearly see the pull ring hole of the pole switch or drop-out fuse, and then the operator will perform the switch switching operation as described above, thereby effectively improving the operation efficiency at night or in poor light.
