Description

technical field [0001] The invention relates to the technical field of ice and snow removal for power transmission lines, in particular to a rotary cutter type overhead power transmission line ice and snow removal device. Background technique [0002] In the winter of our country, in the north or the southern area with more rain and snow, due to the coverage of rain and snow, the transmission line will be frozen or covered with ice and snow, and the icing of the overhead transmission line will cause many problems, such as line burns and transmission line dancing Problems such as ice flashover and ice edge flashover, especially when the amount of snow and ice is large, will cause the transmission line tower to be deformed, broken or even dumped, resulting in damage to power equipment and bringing huge impact and loss to people's lives. The emergency repair of transmission lines is more difficult, and the consumption of economy and human labor is also huge. [0003] At presen...

Problems solved by technology

[0002] In the winter of our country, in the north or the southern area with more rain and snow, due to the coverage of rain and snow, the transmission line will be frozen or covered with ice and snow, and the icing of the overhead transmission line will cause many problems, such as line burns and transmission line dancing Problems such as ice flashover and ice edge flashover, especially when the amount of snow and ice is large, will cause the transmission line tower to be deformed, broken or even dumped, resulting in damage to power equipment and bringing huge impact and loss to people's lives. The emergency repair of transmission lines is more difficult, and the consumption of economy and human labor is also huge.

[0003] At present, most of the deicing operations are to manually remove the snow and ice on the transmission line, but manual deicing has great risks, and the work intensity is high, the work efficiency is low, and the work scope is limited. With the rapid development of intelligent technology, the people have developed some deicing devices for transmission lines. Compared with traditional deicing methods, these deicing devices have the advantages of high efficiency, less manpower consumption, safety and reliability, etc.

[0004] For example, the application number is 201010135359.1, a high-voltage transmission line intelligent deicing robot, including the body and the hanging wire mechanism installed on the body, the driving mechanism, the braking mechanism and the deicing mechanism. This invention has a high degree of automation and low energy consumption. , It can automatically complete the efficient deicing operation to the transmission line, but the deicing mechanism of the invention has defects. For the transmission line, the overhead transmission line is generally hanging in the air due to the effect of gravity, rather than a single Straight line, when the deicing robot is installed on the power line, due to the increase in gravity, the section of the power line to be deiced will be better inclined relative to the deicing mechanism, and the deicing mechanism is fixedly installed on the deicing robot, Keep in a straight line with the de-icing robot. When the de-icing robot is moving forward, due to the inclination of the power line, the de-icing mechanism will inevitably contact the power line, which will cause damage to the power line or damage to the de-icing mechanism. , therefore, during the forward process of the deicing robot, it is a solution to avoid the above problems to be able to adjust the deicing mechanism and the power line as parallel as possible.
