Description

Substation digging bird's nest vertical clamp manipulator

technical field

The utility model relates to a device for digging out a bird's nest, in particular to a vertical clamp-type manipulator for digging out a bird's nest in a substation.

Background technique

The ecological environment near the 500kV substation is good and there are many birds. Although there are many bird repellent devices installed in the substation, there are still many birds nesting on the live equipment in the substation. Especially in the bird breeding season, the equipment There are especially many bird nests in the area, and bird damage is particularly serious. The bird damage caused by birds nesting on the equipment poses a great threat to the safe and reliable operation of the ultra-high voltage power grid, and has become a major safety hazard that endangers the operation of the power grid. In order to prevent equipment tripping and outage caused by bird damage, eliminate bird damage hazards that endanger the safe operation of the power grid, and ensure the safe and reliable operation of the ultra-high voltage power grid, it is particularly urgent and important to remove bird nests in hidden parts of 500kV and 220kV operating equipment.

Because the nests built by birds on the operating equipment are mainly weeds, the weeds in the nests are easy to droop, especially in strong winds and typhoons, the weeds in the bird’s nests are easy to fall with the wind, and may cause short circuits between the operating equipment and A short circuit to ground causes the equipment to trip and shut down. At present, the on-site cleaning and removal of the bird's nest on the operating equipment of the 500kV substation generally uses the gram rod, and the through-hole multi-section gram rod is connected together to pick out the bird's nest in the hidden part of the equipment, so as to achieve the purpose of live removal of the bird's nest on the equipment.

The advantage of using live wire rods is that the operation is simple and convenient, and one or two people can operate it; the disadvantage is that although live work can be carried out, weeds are easy to form for a long time during the operation process to remove the bird's nest on the live equipment. In the drooping state, it is very easy to cause a short circuit to the ground of the operating equipment, causing the equipment to trip and stop operating, and weeds are also easy to float to other operating equipment during the cleaning process, and form a new ground short circuit and phase-to-phase short circuit hidden dangers. In addition, for the bird's nests in some hidden parts of the equipment, it is difficult for the stick to enter and clean up, and the flexibility and effectiveness are greatly reduced. Therefore, there is a serious defect in using the gram stick to remove weeds, which easily leads to the occurrence of equipment outage accidents, and the flexibility and effectiveness are not strong.

Due to the disadvantages of inherently insufficient operability and effectiveness of using the rod to remove weeds on the operating equipment of the 500kV substation, and the bird damage in the equipment area of the 500kV substation is serious, it is urgent and important to remove the bird's nest in the hidden parts of the operating equipment of 500kV and 220kV.
