Low-wind-resistance protection device for preventing pantograph from icing

Abstract

The invention belongs to the field of pantograph maintenance, and particularly relates to a low-wind-resistance protection device for preventing a pantograph from icing, which comprises two fixed spheres, a fixing groove is formed between the two fixed spheres, and a fixing mechanism for connecting the two fixed spheres is arranged outside the fixed spheres. A conversion cavity is formed in each fixed sphere, an energy conversion mechanism is arranged in the conversion cavity, a fan is arranged in each fixed sphere, one side of the fan is communicated with the outside, the other side of the fan is communicated with a heating cavity, an eddy current mechanism is arranged in the heating cavity, and a temperature measuring mechanism for controlling the eddy current mechanism to work is arranged in each fixed sphere. According to the device, the vibration energy of the pantograph can be absorbed and converted into electric energy in a normal state, then the pantograph is heated by the electric energy in a resistance heating mode and an eddy current heating mode under the low-temperature condition, and the situation that the pantograph is frozen is avoided.

Description

technical field [0001] The invention belongs to the field of pantograph maintenance, in particular to a low wind resistance protection device for preventing pantograph from icing. Background technique [0002] The pantograph refers to the equipment that the vehicle obtains electric energy from the catenary, and is mainly installed on the top of the vehicle body, so as to facilitate contact with the outside world. The main types are double-arm type, single-arm type, vertical type and Shijin type. Various types of pantographs are mainly composed of slide plates, upper frames, lower arms (lower frames for double arm bows), underframes, bow springs, transmission cylinders, support insulators and other components. [0003] At present, when vehicles are driving in high-latitude areas, due to the low ambient temperature outside, the pantograph will be prone to icing, especially the hinge joints of the pantograph and other power-connected parts, and these parts will be icy. As a re...

Problems solved by technology

[0003] At present, when vehicles are driving in high-latitude areas, due to the low ambient temperature outside, the pantograph will be prone to icing, especially the hinge joints of the pantograph and other power-connected parts, and these parts will be icy. As a result, the lifting of the pantograph is blocked, and the pantograph cannot be raised or lowered normally, which will affect the actual driving of the vehicle.
