[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0020] Please see Figure 1 and Figure 2This utility model provides a flying trolley for de-icing overhead contact lines, comprising a vehicle body 1, wings 2 mounted on the vehicle body 1, de-icing wheels 3 that can move along the contact network 7, and traveling wheels 4 that can travel on the contact network 7. There are at least one pair of de-icing wheels 3, each pair of which is arranged opposite to each other with a gap between them for the contact network 7 to pass through. Each de-icing wheel 3 is equipped with an ice-breaking structure. The traveling wheels 4 are mounted on the vehicle body 1. In this embodiment, the designed flying trolley can use the wings 2 to fly to a high altitude for operations. Combined with the ice-breaking structures on the de-icing wheels 3, it can easily break up ice during its movement, improving the de-icing efficiency of the contact network 7 and reducing manual labor. Specifically, the flight mechanism of this flying trolley is based on existing drones, using the wings 2 to fly to a high altitude for operations. When the wings 2 propel the vehicle body to the contact network 7, it will hover and maintain balance in the air, which is something existing drones can do. Relevant modules can be purchased commercially and installed on the vehicle body 1. The de-icing wheels 3 are arranged opposite each other. During de-icing, the contact wire 7 passes through the gap between the pair of de-icing wheels 3, and then the traveling wheels 4 travel on the contact wire 7. With the suspension and balance of the wing 2, the ice-breaking structure of the de-icing wheels 3 will move forward along the contact wire 7, thereby breaking the ice on the contact wire 7. Usually, the ice on the contact wire 7 is not very thick. As long as the balance of the ice covering the contact wire 7 is disrupted, the ice will fall off on its own. In addition, when the contact wire 7 passes between the two de-icing wheels 3, the two de-icing wheels 3 can also clamp the contact wire 7. In this way, with the wing 2 and the traveling wheels 4, the flying vehicle can move along the extension direction of the contact wire 7. Preferably, the vehicle body 1 is equipped with a heating component for heating the ice-breaking structure, which can increase the temperature of the ice-breaking structure and improve the de-icing efficiency and effect.

[0021] Please see Figure 1 and Figure 2 The ice-breaking structure includes serrated blocks 8 disposed on the de-icing wheel 3, with each pair of serrated blocks 8 on the de-icing wheel 3 arranged opposite to each other, and the gap located between the two serrated blocks. In this embodiment, as... Figure 3 As shown, the serrated block 8 has a structure that can break ice when the de-icing wheel 3 clamps the contact wire 7 and slides along the direction of the contact wire 7. The heating component described above can be further refined into a thermistor or a heating wire, which can be built into the serrated block 8. The serrated block 8 can be made of a thermally conductive metal. Of course, in addition to using the serrated block 8, other forms can also be used, such as a shovel-shaped structure, which can scrape off the ice as the de-icing wheel 3 moves.

[0022] Please see Figure 1 and Figure 2 The de-icing wheel 3 is a roller with its axis set vertically, and the traveling wheel 4 is a roller with its axis set horizontally. Figure 2The position of the traveling wheel 4 is for illustrative purposes only, and perspective is used to show its location. The traveling wheel 4 is horizontally positioned and can roll above the contact wire 7. The de-icing wheel 3 clamps the contact wire 7 and slides along the extension direction of the contact wire 7 under the drive of the traveling wheel 4, thereby breaking and scraping away the ice.

[0023] Please see Figure 1 and Figure 2 The vehicle body 1 has multiple supports 5, and each support 5 is equipped with a wing 2. In this embodiment, there are multiple wings 2, such as the four wings 2 shown in this embodiment, which are symmetrically distributed to maintain the balance of the vehicle body 1.

[0024] Please see Figure 1 and Figure 2 The de-icing wheels 3 are in two pairs, spaced apart at the front and rear ends of the vehicle body 1. In this embodiment, there can be multiple pairs of de-icing wheels 3, such as the two pairs of wings 2 shown in this embodiment, respectively located at the front and rear of the vehicle body 1. This front-to-rear clamping arrangement helps maintain a more stable state for the vehicle body 1. Similarly, multiple walking wheels 4 can be provided, with walking wheels 4 at both the front and rear, providing a more stable walking mechanism. The rolling of the walking wheels 4 can be achieved using existing micro-motor rolling methods or other existing rolling methods, or entirely using the wings 2 to provide driving force. Existing drones can perform various maneuvers in the air, but this embodiment involves a single action, which is easy to implement at low cost, and the walking wheels 4 are only used for balancing and walking.

[0025] Please see Figure 1 and Figure 2 The flying vehicle also includes a clamping mechanism for adjusting the gap between each pair of de-icing wheels 3. In this embodiment, the clamping mechanism can adjust the clamping force between the de-icing wheels 3, thereby adjusting the clamping force on the contact wire 7. This improves the stability of the vehicle body 1 moving on the contact wire 7, and also applies force to squeeze the ice, making the ice break up faster. The force is carefully controlled during the design to find a balance point and avoid damaging the contact wire 7.

[0026] Please see Figure 1 and Figure 2The flying vehicle also includes a control unit that controls the operation of the wings 2 and the wheels 4, and the control unit is mounted on the vehicle body. In this embodiment, by designing the control unit, the foundation can be laid for the semi-automatic or even fully automated operation of the flying vehicle. The control unit can control the operation of the wings 2 and the wheels 4, and by solving the work of these two driving force providers, automated operation can be achieved. Preferably, the control unit has a built-in control circuit board and a power supply for the wings 2 and the wheels 4. The control circuit board is used to control the rotation of the wings 2 and the rotation of the wheels 4. The control unit includes a housing, and a power supply can be installed inside the housing to supply power to the drive components. The control circuit can also be designed to control the rotation of the wings 2 and the rotation of the wheels 4. The control of these two parts can be designed separately on the circuit board or integrated into the design. Both of these controls are existing controls, such as the rotation control of the wings 2 on drones and the rotation control of the wheels 4 on toy cars. These are very existing, and control circuit boards can be purchased on the market. Therefore, the specific control logic will not be described in detail here. Preferably, the control unit is equipped with a sensor 6, such as an infrared sensor 6, an attitude sensor 6, a distance sensor 6, etc., which enables more precise control. The infrared sensor 6 can sense the contact wire 7, thereby determining its extension direction and guiding the operation of the forward clamping motor, allowing the vehicle to adaptively navigate along the contact wire 7 in geometric space. This lays the foundation for the fully automated operation of the flying vehicle. Preferably, the control unit is equipped with a signal receiver. By designing the signal receiver, a remote control can be used to control the flight and movement of the flying vehicle, similar to the remote control of a drone. This is existing technology and will not be detailed here. Preferably, a remote control and monitoring module can also be set up, enabling the vehicle to have remote control and real-time monitoring functions, facilitating remote operation and data collection by operators. Preferably, a GPS or Beidou navigation system can also be set up to achieve remote control and monitoring of the vehicle. Preferably, lightweight materials are used to reduce the overall weight of the vehicle. The structural design should fully consider strength and rigidity to ensure the stability and durability of the vehicle.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
