[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0028] This specific embodiment provides a high-speed railway transmission line deicer to solve the technical problem that the deicing device in the prior art requires manual operation and is inconvenient for snow removal.

[0029] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to the solutions required as the utility model described in the claims.

[0030] Reference Figure 1-Figure 4 The utility model provides a high-speed railway transmission line deicer, comprising a first slide rail 1, a second slide rail 3, a left deicing device 2, and a right deicing device 4. The first slide rail 1 and the second slide rail 3 are symmetrically installed on the pantograph bracket; the left deicing device 2 is slidably installed on the first slide rail 1, and the right deicing device 4 is slidably installed on the second slide rail 3. The left deicing device 2 is close to the right deicing device 4 and there is a space for accommodating an ice layer;

[0031] The left deicing device 2 includes a first shell 21, a first coil 23, an ultrasonic emitting device 24, and a first current guide piece 22 for cutting the magnetic field of the transmission line. The first coil 23 is arranged in the first shell 21, and the axis of the first coil 23 is in the same direction as the movement of the first shell 21. The first current guide piece 22 extends out of the first shell 21, and the first coil 23 is connected to the first current guide piece 22. The first current guide piece 22 cuts the magnetic flux lines generated around the transmission line to generate current, and the current is transmitted to the first coil 23, so that the first coil 23 also generates a first magnetic field, wherein the first coil 23 is electrically connected to the ultrasonic emitting device 24 to supply power to the ultrasonic emitting device 24, so as to facilitate the ultrasonic emitting device 24 to emit energy;

[0032] The right de-icing device 4 includes a second shell 41, a second coil, an ultrasonic receiving device 43, and a second current guide piece 42 for cutting the magnetic field of the transmission line. The second coil is arranged in the second shell 41, and the axis of the first coil 23 is in the same direction as the movement of the first shell 21. The second current guide piece 42 extends out of the second shell 41, and the second coil is connected with the second current guide piece. The second current guide piece 42 cuts the magnetic flux lines generated around the transmission line to generate current, and the current is transmitted to the second coil so that the second coil generates a second magnetic field. The second coil is electrically connected to the ultrasonic receiving device 43 to power the ultrasonic receiving device, so that the ultrasonic receiving device 43 can receive energy conveniently.

[0033] In order to enable the left de-icer 2 and the right de-icer 4 to approach each other when cutting the magnetic field generated by the transmission line, the first magnetic field interacts with the second magnetic field to attract the left de-icer 2 and the right de-icer 4 to approach each other, that is, if the first coil 23 is close to the first coil 23 to generate an N-pole magnetic field, the second coil is close to one side of the first coil 23 to generate an S-pole magnetic field, and according to the property of mutual attraction between opposite magnetic poles, the left de-icer 2 and the right de-icer 4 will begin to approach the middle transmission line, and at the same time, the ultrasonic transmitting device 24 transmits energy to the ultrasonic receiving device, and the energy will crack the ice layer sandwiched between the left de-icer 2 and the right de-icer 4, making it easier for the ice layer to fall off, and then facilitating the contact between the pantograph and the transmission line.

[0034] With such arrangement, when the train is moving, the first current guide plate 22 and the second current guide plate 42 cut the magnetic flux lines generated by the transmission line to generate current, and the current is transmitted to the first coil 23 and the second coil so that the first coil 23 and the second coil generate magnetic poles that can attract each other, so that the left de-icing device 2 and the right de-icing device 4 are close to each other, and at the same time, electric energy is provided to the ultrasonic transmitting device 24 and the ultrasonic receiving device, and the ultrasonic transmitting device 24 emits high-pressure sound waves to crack the ice layer, thereby causing the ice layer to fall off.

[0035] In this embodiment, a vibrator 5 is provided on the side close to the left deicing device 2 and the right deicing device 4. The vibrating rod of the vibrator 5 reciprocates toward the direction of the ice layer to accelerate the falling of the ice layer on the transmission line.

[0036] In this embodiment, in order to prevent the left de-icing device 2 from detaching from the first slide rail 1 and the right de-icing device 4 from detaching from the second slide rail 3, limit members are provided at both ends of the first slide rail 1 and the second slide rail 3, and the limit members prevent the left de-icing device 2 or the right de-icing device 4 from continuing to slide.

[0037] In the present embodiment, in order to allow the left de-icing device 2 to move on the first slide rail 1 and prevent the left de-icing device 2 from detaching from the first slide rail 1 when in use, the first slide rail 1 includes a first slide 11, a second slide 12, and a third slide 13. The first slide 11 is arranged above the first slide rail 1, the first slide 11 is arranged below the first slide rail 1, and the second slide 12 is arranged on both sides of the first slide rail 1. In this way, the left de-icing device 2 can be limited up, down, left and right at the same time, and the left de-icing device 2 can be prevented from shaking left and right. Three first rollers 25 are arranged on both sides of the first shell 21, and the first rollers 25 are respectively matched with the first slide 11, the second slide 12, and the third slide 13.

[0038] In order to facilitate the connection between the first shell 21 and the first slide rail 1, the first shell 21 includes a first connecting part 211, a second connecting part 212, and a third connecting part 213 which are connected in sequence. A first space for the first slide rail 1 to pass through is formed between the first connecting part 211 and the third connecting part 213. The second connecting part 212 is arranged on both sides of the first space. The first rollers 25 are respectively arranged below the first connecting part 211, on the side wall of the second connecting part 212, and on the top of the third connecting part 213. That is, the first slide rail 1 is inserted into the first shell 21, which can effectively prevent the first shell 21 from detaching from the first slide rail 1.

[0039] In the present embodiment, in order to allow the right de-icing device 4 to move on the second slide rail 3 and prevent the right de-icing device 4 from detaching from the second slide rail 3 when in use, the second slide rail 3 includes a fourth slide 31, a fifth slide 32, and a sixth slide 33. The fourth slide 31 is arranged above the second slide rail 3, the sixth slide 33 is arranged below the second slide rail 3, and the fifth slide 32 is arranged on both sides of the second slide rail 3. In this way, the right de-icing device 4 can be limited in the upper, lower, left and right directions at the same time, and the right de-icing device 4 can be prevented from shaking left and right. Three second rollers are arranged on both sides of the second shell 41, and the second rollers cooperate with the fourth slide 31, the fifth slide 32, and the sixth slide 33, respectively.

[0040] To facilitate the connection between the second shell 41 and the second slide rail, the second shell includes a fourth connecting part 411, a fifth connecting part 412, and a sixth connecting part 413 which are connected in sequence. A second space for the second slide rail to pass through is formed between the fourth connecting part 411 and the sixth connecting part 413. The fifth connecting part 412 is arranged on both sides of the second space. The second rollers are respectively arranged under the fourth connecting part 411, on the side wall of the fifth connecting part 412, and on the top of the sixth connecting part 413. That is, the second slide rail is inserted into the second shell, which can effectively prevent the second shell from detaching from the second slide rail.

[0041] In this embodiment, the first current conductors 22 are provided at three locations and are evenly distributed along a direction perpendicular to the movement of the first shell 21, and the first current conductors 22 are connected in series. The second current conductors 42 are provided at three locations and are evenly distributed along a direction perpendicular to the movement of the second shell 41, and the second current conductors 42 are connected in series. This can increase the current passing through the first coil 23 and the second coil.

[0042] In this embodiment, the first slide rail 1 and the second slide rail 3 are both configured to be arc-shaped. When not in use, under the action of gravity, the left de-icing device 2 slides along the first slide rail 1 to the bottom of the first slide rail 1; the right de-icing device 4 slides along the second slide rail 3 to the bottom of the second slide rail 3.

[0043] In this embodiment, a first thermostat is provided on the back of the ultrasonic transmitting device 24 and the first slide rail 1, and a second thermostat is provided on the back of the ultrasonic receiving device 43 and the second slide rail 3. The first thermostat is connected to the first coil 23, and the second thermostat is connected to the second coil. In this way, when the first current blade and the second current guide blade 42 cut the magnetic flux lines, the first thermostat and the second thermostat can receive electrical energy and generate heat, thereby preventing the ultrasonic transmitting device 24, the back of the first slide rail 1, the ultrasonic receiving device 43, and the back of the second slide rail 3 from being cold and frozen, thereby affecting their use.
