Abstract
Description
Technical Field
[0001] The invention relates to the technical field of deicing of contact lines of electric vehicles, and relates to a deicing device for contact lines. Background Art
[0002] my country has a vast territory and complex meteorological conditions. The weather is unpredictable in winter and early spring. Snow and freezing rain are frequent in severe cold weather. Special climatic conditions cause ice on the power contact network, affecting the operation of electrified vehicles that rely on the contact network for power. The current deicing methods mainly include hot sliding deicing, DC heating wire deicing and manual knocking deicing. The above methods have problems such as limited use conditions, high cost, low efficiency and the need to wait for a window period. If there is a climate phenomenon of continuous freezing rain, electrified vehicles can only wait for rescue by diesel locomotives. In order to ensure the normal operation of electrified vehicles, it is necessary to solve this problem. Summary of the invention
[0003] The present invention provides a contact network deicing device. The contact network deicing device includes: an air motor, an ice-removing knife, a copper-based powder protective pad, a base that can be moved left and right, a contact network cable tracking computer, and a lifting bracket. The basic external dimensions are consistent with the pantograph. The deicing method is to drive the ice-removing knife to saw and cut off large pieces of ice on the contact network through the high-speed rotation of the air motor, and at the same time, the copper-based powder protective pad removes the residual ice on the contact network to make the pantograph and the contact network in good contact. The present invention effectively solves the problem that the electric vehicle loses power due to the influence of the contact network ice on the pantograph. Moreover, it has many advantages such as high efficiency, low cost, and no need to wait for the window period, which ensures the safe operation of the vehicle.
[0004] Preferably, the de-icing device is powered by a pneumatic motor.
[0005] Preferably, the de-icing blade rotates and is circular with serrations.
[0006] Preferably, the copper-based powder protective pad is circular and its thickness can be adjusted as required. The edge is toothed and the upper part of the circular surface is file-marked. The protective pad can also be made integrally with the de-icing blade.
[0007] Preferably, the lifting bracket can be a finished pantograph lifting bracket.
[0008] Preferably, a base that can be moved left and right.
[0009] Preferably, the overhead line cable is tracked by a computer.
[0010] The contact network deicing device provided by the present invention is composed of a lifting bracket, a contact network cable tracking computer and a deicing mechanism. The deicing mechanism includes a mounting seat that can be moved left and right, an air motor, a deicing knife, and a copper-based powder protective pad. The air motor deicing knife and the copper-based powder protective pad are installed on the mounting seat that can be moved left and right.
[0011] The lifting bracket is installed at a preset position on the top of the rail vehicle. Through the lifting action, the de-icing mechanism and the overhead contact network are brought into contact with the power supply cable.
[0012] The copper-based powder protective pad is located between the contact network cable and the de-icing knife, ensuring that the de-icing knife blade always maintains a safe distance from the contact network. The de-icing knife and the copper-based powder protective pad rotate horizontally to remove large ice blocks on the contact network cable. The copper-based powder protective pad directly rubs against the contact network cable to remove residual thin ice, ensuring good contact between the bow and the catenary.
[0013] In order to reduce wear, the contact network is structured in a zigzag shape. In order to ensure that the combination of a de-icing knife and a copper-based powder protective pad is always in contact with the contact cable, the contact network cable tracking computer calculates the overlapping position of the contact network cable and the de-icing knife based on Beidou satellite, GPS, video images, contact network poles or other geographical markers, and controls the mounting base that can move left and right to keep the de-icing knife under the contact network cable at all times.

[0017] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. The embodiments described herein are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by the art without creative work are within the scope of protection of the present invention.
[0018] Please refer to Figure 1 , Figure 2 . Figure 1 It is a schematic diagram of the overall structure of a specific implementation method provided by the present invention, including a de-icing blade and a copper-based powder protective pad assembly 3, a pneumatic motor 5, a lifting bracket 6, a controllable left and right motion mounting seat 7, and a contact network cable tracking computer 9. Figure 2Middle de-icing blade 2, copper-based powder protection pad 1, de-icing blade superimposed on copper-based powder protection pad assembly 3, side view of de-icing blade superimposed on copper-based powder protection pad assembly 4, contact line diagram 8.
[0019] Figure 2 The copper-based powder protective pad 1 has serrations and file marks on the edge and file marks on the round surface, which are used to keep a safe distance between the contact line 8 and the de-icing blade 2 and to remove residual thin ice on the contact line 8.
[0020] Figure 2 The de-icing blade 2 in the embodiment of the present invention is circular and has serrations. Under the guidance of the de-icing theory of the present invention, it can be transformed into other tools with the same functions as sawing, planing and cutting and has power for removing ice from the contact network.
[0021] Figure 2 The de-icing blade 2 and the copper-based powder protection pad 1 are superimposed and combined into a de-icing blade and copper-based powder protection pad combination 3. After the combination is completed, the side view is as shown in 4. The de-icing blade 2 superimposed on the copper-based powder protection pad 1 combination 3 can also be manufactured by an integrated process. The purpose achieved by the finished product is the same as the purpose of this patent.
[0022] Figure 1 The pneumatic motor 5 is installed horizontally on a mounting seat 7 that moves left and right.
[0023] Figure 1 The middle lifting frame 6 rises until the copper-based powder protection pad 1 contacts the contact line, and the compressed air is started to drive the pneumatic motor 5 to drive the de-icing knife 2 superimposed on the copper-based powder protection pad 1 combination 3 to rotate. The de-icing knife 2 superimposed on the copper-based powder protection pad 1 combination 3 rotates horizontally at high speed. When the train moves forward, the ice on the contact line is broken and falls by the horizontally installed de-icing knife 2. Because the copper-based powder protection pad 1 always keeps a certain non-contact distance between the de-icing knife 2 and the contact line 8, the high-speed rotating de-icing knife 1 will not damage the contact network 8. Since the copper-based powder protection pad 1 is made with serrations and file marks, the serrations and file marks can remove the thin ice remaining on the contact line 8, so that the bow-net contact is good and the occurrence of arcing is reduced.
[0024] In order to reduce wear, the contact network is constructed in a zigzag shape. In order to ensure that the de-icing knife superimposed on the copper-based powder protective pad assembly 3 is always in contact with the contact cable 8, the contact network cable tracking computer 9 is required to calculate the overlapping position of the contact network cable and the de-icing knife according to the Beidou satellite, GPS, video images, contact network poles or other geographical markers, and control the mounting seat 7 that can move left and right to keep the de-icing knife under the contact network cable. The above description of the disclosed embodiments enables professionals and technicians in this field to implement or use the present invention. Various modifications to these embodiments will be easy for professionals and technicians in this field, and the general principles in the description can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the examples used in this article but will conform to the widest range consistent with the principles and novel features disclosed in this article.
