BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 is a schematic diagram of a radial wheel type impact wire ice and snow mechanism installed on the top of a locomotive (1); Figure 2 It is a left side schematic diagram of the top of a locomotive (1) with a radial wheel type impact wire ice and snow mechanism installed; Figure 3 This is the main view of the frame of the radial wheel impact wire ice and snow mechanism Figure 4 It is a left side schematic diagram of a frame of a radial wheel type impact wire ice and snow mechanism; Figure 5 It is a schematic diagram of the radial wheel front view; Figure 6 It is a schematic diagram of the left side view of the radial wheel; The principles and beneficial effects of the present invention are: First, the present invention utilizes the principle of whipping a gyroscope. After whipping the gyroscope, the whip can smoothly pass through the side of the gyroscope close to the person by inertia, thus completing a whipping process.

[0012] Second, the present invention utilizes the opening and closing principle of door and window hinges. The dynamic T-shaped punch is similar to the principle of the two pieces of door and window hinges rotating around the central axis to achieve opening and closing. One piece of the hinge is fixed to the fixed door outer frame of the wall, and the other piece is connected to the frame of the movable door. The door rotates freely around the central axis of the hinge. From the height of the plane coordinates of the door rotating 90 degrees, the height of the door changes from 90 degrees to 0 degrees, that is, the height of the door at 90 degrees is the highest, which is the width of the door, and the height is 0 when the door is 0 degrees. The dynamic T-shaped punch utilizes the principle of the change in the opening and closing height of the door. After impacting the wire, the height of the radiation head is adjusted to be lower than the height of the wire, and it passes smoothly under the wire, repeating the process of impacting the wire in the next cycle.

[0013] 3. The present invention utilizes the principle of a two-section stick or a three-section stick. When the front end stick hits the target, the distance of the hitting stick changes simultaneously by virtue of the inertia force of the hitting stick. The distance of the hitting stick to the side of the striker becomes closer. The hitting stick passes smoothly through the body of the person being struck, completing an effective strike, and then repeats the strike at other positions for a second or more time.

[0014] 4. The present invention provides a radial wheel type impact wire ice and snow mechanism which has a simple structure, is easy to install, and is safe and reliable.

[0015] 5. The installation of this mechanism does not change other roof structures. The roof can be used according to local conditions, breaking the rigid way of thinking and realizing the transition from manual to mechanical deicing.

[0016] 6. Efficiently remove ice and snow from the wires to effectively eliminate arcing caused by poor contact between the pantograph and the wires, and avoid the pantograph being burned by the arc, causing the vehicle to lose power and stop running.

[0017] 7. Install the mechanism of the present invention to solve the problem that the normal operation of traffic is seriously affected and passengers cannot arrive at the destination on time; 8. Compared with the existing artificial deicing methods, artificial deicing has high labor intensity and low work efficiency, and cannot quickly and completely solve the practical problem of ice on the conductors of the entire section.
