Description

A special tool and method for live replacement of bird-repelling windmills by ground potential operation method

Technical field:

The invention relates to a special tool and method for live replacement of a bird-repelling windmill by the ground potential operation method, which is widely used in live installation and replacement of a bird-repellent windmill by the ground potential operation method in a 10kV power distribution line of a power system, and belongs to the live maintenance site of a power distribution line technology field.

Background technique:

In recent years, with the enhancement of people's awareness of environmental protection and the continuous improvement of the ecological environment, the population, number and range of activities of birds living in nature have gradually increased, and birds nest on the line towers. In the statistics of power line accidents in recent years, accidents such as trips caused by birds not only gradually increased, but also showed a rapid upward trend, which had a great impact on the safe operation of the power grid. This has brought a lot of trouble to the power sector. The bird-repelling windmill has solved this problem for the power sector by ensuring that the power grid will not be affected by bird damage under the premise of not harming birds.

At present, the bird-repelling windmill is made of high-quality high-strength materials, which are corrosion-resistant, light in weight and easy to start with a breeze. According to the characteristics of birds that are afraid of light, the device adopts rotating and reflective bird-repelling methods. The bird-repelling windmill rotates under the action of the wind, and the mirror on the fan blade produces light projection, so that some birds are exposed to strong light or their own shadows. Frightened by their reflexes, it drives them away from power pole lines and prevents them from nesting on poles. The bird-repelling windmill is mainly used for power poles and towers of distribution lines to prevent them from being damaged by birds and cause line tripping accidents, and to improve the reliability of line power supply.

The bird repelling windmill has played a significant role in repelling birds through years of practical use and improvement, and now it has become the preferred solution for power distribution lines to repel birds. However, in the on-site work of power distribution lines, the installation and replacement of the bird-repelling windmill generally needs to be carried out when the line is powered off. After the line is powered off, the electric workers climb the pole to the cross arm through the foot buckle, and complete the replacement through high-altitude operations. This method consumes a lot of physical energy for electric power workers, and there are potential safety hazards in high-altitude operations. Simultaneously, because every time replacement windmill of driving bird will all be blacked out, therefore can cause some power users to have blackout, resident's life and factory enterprise all will be greatly affected, have hindered the development of economy and society and people live and work in peace and contentment.

If the method of live work is adopted, only the insulated bucket arm method or the insulated platform method can be used in the past. Using the insulated arm truck method, live workers drive the insulated arm truck to the vicinity of the line installation position, and then install or replace the bird-repelling windmill by operating the insulating arm and insulating bucket to the working position after supporting the insulating bucket truck in place. This approach has two disadvantages. One is that the scope of operation is limited. When the terrain of the distribution line is uneven or there are many buildings around, the insulated arm truck cannot approach the working position, so the insulated arm truck cannot be used for operation. Using the insulating platform method, the insulating platform is manually installed by electric workers. Due to the heavy weight of the insulating platform, it still needs multiple people to carry it in areas where the terrain is rough and cannot be reached by transport vehicles, and the operation is time-consuming and laborious.

Therefore, there is an urgent need to develop a special tool and method for the operator to use the foot buckle to climb the pole to complete the live installation of the ground potential operation method and replace the bird-repelling windmill, so as to overcome the time-consuming and labor-intensive problems that the insulating bucket truck cannot reach or the work of multiple people is time-consuming and laborious. , to ensure the safety of installing and replacing the bird-repelling windmill, and to improve operating efficiency.
