Description

Technical Field

[0001] The invention relates to a cleaning device, in particular to a multifunctional foreign matter charged cleaning device for a power grid, belonging to the technical field of power equipment. Background Art

[0002] With the rapid development of my country's national economy and the improvement of people's living standards, the importance of electricity has become increasingly significant. Ensuring the stable and reliable operation of the power system has become a basic requirement for the power supply industry in various sectors of the national economy. However, with the rapid development of power grid construction, the number of overhead transmission lines built in suburban towns has gradually increased, and the external environment faced by line operation has become increasingly complex, and the threats faced have also increased accordingly. In recent years, environmental protection pressure has increased. The slag piles on construction sites are usually covered with dust-proof nets, which often have the phenomenon of not being pressed and are easily blown away by the wind; with the further development of agriculture, the construction of vegetable greenhouses has also increased year by year. The greenhouse film is easily damaged in windy weather and blown off the ground wire; in addition, kite flying in spring and autumn is deeply loved by the masses, and kite flying under high-voltage lines and kite line breakage occur from time to time. In particular, in recent years, there has been an increase in strong winds and strong convective weather, and it often happens that thin films, dust-proof nets and other strip-shaped or entangled objects are rolled up by the wind and hung on the overhead transmission lines, posing a serious threat to the safe and reliable operation of overhead transmission lines.

[0003] The tripping of overhead transmission lines caused by foreign objects such as kites, plastic sheets, tin foil strips, and dust nets is one of the common forms of external force damage. The tripping accidents have the following main characteristics: first, it is highly time-sensitive. In the spring and autumn kite-flying seasons, it is easy for the kite line to break, causing the kite or kite line to hang on the overhead transmission line; after strong convective winds in summer, plastic sheets, tin foil strips, and dust nets are also very easy to be blown onto the overhead transmission line; second, it is highly regional. Usually, the lines around greenhouses, construction sites, and fruit trees are easily affected by floating foreign objects such as plastic sheets, dust nets, and tin foil strips; third, it is difficult to prevent. In recent years, overhead transmission lines have been distributed in many points and over a wide area. It is also difficult to track and persuade people flying kites offline in a timely manner. Severe convective weather is sudden and difficult to accurately predict. The range of foreign objects scattered under strong winds is large, and it is not easy to grasp the situation of foreign objects on the line. All these have brought challenges to the prevention of foreign objects on overhead transmission lines.

[0004] Nowadays, the materials of kite lines are diversified, mostly cotton rope, nylon rope, fishing line and steel wire. Among them, kite lines containing metal wires pose the greatest threat to the safe and reliable operation of overhead power transmission lines. Once the line is broken, it will be scraped off and entangled on the conductor and ground wire under the action of wind, which will cause single-phase grounding or phase-to-phase short circuit of the overhead power transmission line, directly causing line tripping accidents and even casualties. Although kite lines made of other insulating materials are not conductive, scraping and entangled on overhead power transmission lines will not immediately cause line tripping, but when encountering high humidity weather such as rain, snow or fog, the kite line will absorb water and become a good conductor from a poor conductor, which will eventually cause the overhead power transmission line to trip, posing a serious threat to the safe and reliable operation of the line.

[0005] Similarly, for insulating materials such as dust screens and plastic sheets, if they encounter humid weather such as rain and fog, their insulation performance may deteriorate, causing short circuits and power outages. The tin foil strips commonly used to prevent birds in orchards are directly conductive, and once the length reaches a certain value, it will directly cause discharge and tripping, which poses a great threat to the safe and reliable operation of overhead power transmission lines.

[0006] Transmission lines are the main carrier of power transmission and an important part of the power system. They play a vital role in the safe and stable operation of the system. Due to the wide distribution of transmission lines, the complex natural environment, and the impact of people's production and life, it is very easy for foreign objects such as balloons, kites, plastics, and bird nests to attach to the lines. If these foreign objects are not discovered and cleaned up in time, they will affect the normal operation of the transmission lines and even cause power outages or safety accidents. Transmission line image inspection can effectively detect foreign objects, eliminate hidden dangers in time, and prevent foreign objects from endangering the normal operation of transmission lines. It can better overcome the problems of high cost, easy missed inspection, and low efficiency of traditional manual inspection methods.

[0007] Substations are mostly built outdoors and in an open-air construction form. Outdoor substations are affected by natural factors, and floating objects are often blown into substations due to natural conditions such as strong winds and bad weather. For example, in windy weather, waste such as woven bags, plastic films, plant branches, kite lines, and rubber strips fly into the substation with the wind. These wastes are easily attached to power equipment such as transformers, circuit breakers, and high-voltage transmission lines, causing equipment failures, short circuits, tripping, and even fires, posing a serious threat to the safety of the substation. In order to avoid the above situation, substation staff need to frequently patrol such power equipment. Once foreign objects are found, they need to use tools to split, destroy, and remove the foreign objects. The existing cleaning work requires staff to use ladders, elevators, and other climbing equipment to rise to a high place. This cleaning method is not only inefficient, but also highly dangerous. If you are not careful, it will cause a person to fall. In addition, the cleaning of foreign objects on existing power equipment can only be carried out in a power outage state, and it cannot be operated with power, which will have an adverse effect on the normal operation of the substation. Therefore be necessary to improve the prior art. Summary of the invention
