[0030] The technical solution of the present invention is described below in conjunction with the accompanying drawings.

[0031] In the embodiments of the present invention, words such as "exemplarily" and "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "example" in the present invention should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of the word "example" is intended to present the concept in a specific way. In addition, in the embodiments of the present invention, the meaning expressed by "and / or" can be both, or it can be either of the two.

[0032] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0033] The embodiment of the present invention provides a thermal deicing device for electric wires. Figure 1 This is a schematic diagram of the structure of a thermal deicing wire deicing device provided by an embodiment of the present invention. Figure 1 The device comprises: an ice cutter, a burner 3, a flow guide chamber, a walking mechanism and a bracket 7.

[0034] Among them, the walking mechanism is hung on the wire 4, and the walking mechanism has good grip and stability, ensuring that the device can move smoothly under icy, slippery and other weather conditions. In addition, the ice cutter, the burner 3 and the walking mechanism are sequentially arranged on the bracket 7. That is, through the connection between the walking mechanism and the bracket 7, the ice cutter and the burner 3 can be arranged on the wire 4 to process the ice 11 on the wire 4.

[0035] Specifically, the ice cutter is arranged on at least one side of the electric wire 4, and the ice cutter is used to cut off the ice growing circumferentially of the electric wire 4.

[0036] The outlet of the burner 3 faces the preset heating area on the wire 4, and the outlet of the burner 3 is at a preset distance from the preset heating area, so that the high-temperature airflow generated by the combustion of the fuel in the burner 3 can be used to blow the ice 11 on the wire 4. The preset distance can be set as needed, for example, 0.5-30 cm.

[0037] The guide cavity wraps the preset heating area to form an airflow channel, and the opening of the guide cavity is opposite to the burner 3. Therefore, the jet airflow flows along the guide cavity, thereby extending the airflow heating time of the wire 4, and the ice 11 is melted and blown away by the airflow, so that the wire 4 can be de-iced efficiently.

[0038] The ice cutter, burner and guide chamber are all fixed on the bracket 7, driven by the traveling mechanism, and move along the electric wires to achieve continuous deicing of the electric wires.

[0039] The hot ice melting wire deicing device provided in the embodiment of the present invention can cut off the ice ridges growing circumferentially on the wire 4 by an ice ridge cutter, and then use the fuel combustion in the burner 3 to generate a high-temperature airflow to spray the ice 11 on the wire 4, and the sprayed airflow flows along the guide cavity. The airflow continues to heat the ice 11 that is not completely melted, and the ice 11 is blown away by the airflow after melting, thereby achieving efficient deicing of the wire 4. Moreover, this device can de-ice without power outage, avoiding economic losses in the de-icing process.

[0040] Furthermore, in an embodiment provided by the present invention, the ice scissor comprises: a power motor 1 and a blade 2, the power motor 1 is arranged on a bracket 7, and the blade 2 is connected to the output shaft of the power motor 1; the power member outputs a rotary or reciprocating motion. The number and setting direction of the blades 2 can be set as required, for example, the number is 1 to 8, and they are installed around the wire 4, so that the ice scissors of the wire 4 can be cut from multiple directions to improve the deicing effect.

[0041] In one embodiment provided by the present invention, the burner 3 is a turbojet, a gasoline engine or a diesel engine. Moreover, the burner 3 and the electric wire 4 may be at a preset angle, which may be set as needed, for example, 5 to 90 degrees. That is, the high-temperature airflow generated after combustion sprays the ice-covered electric wire 44 at an angle of 5 to 90 degrees. After the high-temperature airflow melts the ice 11, the melted water layer is blown away, thereby achieving rapid melting of the ice 11.

[0042] Furthermore, the position and inclination of the burner 3 can be adjusted, and the temperature of the air flow sprayed to the surface of the wire does not exceed 200° C., ensuring the safety of the wire.

[0043] In one embodiment provided by the present invention, the walking mechanism includes a guide wheel 8 and a driving wheel 9. The guide wheel 8 is located at the front and has an obstacle-passing function, and the driving wheel 9 is driven by a motor or an internal combustion engine. Specifically, the guide wheel has a retractable structure, and when encountering an obstacle, it is retracted inward through the retractable structure to achieve the obstacle-passing effect.

[0044] Furthermore, in an embodiment provided by the present invention, the walking mechanism further includes: a clamping wheel 10, the clamping wheel 10 and the driving wheel 9 are arranged on both sides of the wire 4, and the clamping wheel 10 is connected to the bracket 7 through a first telescopic rod 15. Through the first telescopic rod 15, the wire can be clamped between the clamping wheel 10 and the driving wheel 9.

[0045] Specifically, the guide wheel 8 is a V-shaped wheel, located at the front and has an obstacle-passing function. The guide wheel 8 has a mechanical crushing effect on the ice layer of the wire, enhancing the deicing effect. The driving wheel 9 and the clamping wheel 10 form a wheel set, which is close to the deiced wire 4. The driving wheel 9 and the clamping wheel 10 are both V-shaped wheels. The driving wheel 9 adopts a rough surface to increase the friction between the wheel and the wire, and is driven by a driving motor 12 or an internal combustion engine.

[0046] During the operation of the device, the first telescopic rod 15 is shortened, and the clamping wheel 10 and the driving wheel 9 hold the wire tightly, providing friction for the device to go online. During the offline process of the device, the first telescopic rod 15 is extended, and the device can be separated from the wire.

[0047] Furthermore, in an embodiment provided by the present invention, it also includes: a battery fuel tank 17, the battery fuel tank 17 is connected to the bracket 7; the battery fuel tank 17 is electrically connected to the ice cutter and the walking mechanism, and the battery fuel tank 17 contains the power required by the ice cutter and the walking mechanism.

[0048] The battery fuel tank 17 is connected to the burner 3 via a fuel pipeline, and the battery fuel tank 17 contains the fuel required by the burner 3 .

[0049] It should be noted that the battery fuel tank 17 has a certain weight, and the bracket 7 and a part of the parts connected to the bracket 7 are arranged on one side of the wire 4, and the battery fuel tank 17 is arranged on the other side of the wire 4. Therefore, based on the own weight of the battery fuel tank 17, the battery fuel tank 17 can usually be located on the lower side of the wire 4, while the bracket 7 and a part of the parts connected to the bracket 7 are located on the upper side of the wire 4.

[0050] Furthermore, in an embodiment provided by the present invention, the battery fuel tank 17 is located between the driving wheel 9 and the guide wheel 8, and is connected to the bracket 7 by a rotating mechanism 18 to ensure that the device does not tip over when traveling uphill or downhill.

[0051] Furthermore, in an embodiment provided by the present invention, the guide wheel 8, the driving wheel 9 and the bracket 7 are connected via a shock absorbing assembly to reduce the vibration of the bracket 7 and some parts connected to the bracket 7 to ensure the de-icing effect.

[0052] Furthermore, in an embodiment provided by the present invention, the shock absorbing assembly includes a connecting rod mechanism 13 and a shock absorbing spring 14, and the connecting rod mechanism 13 is arranged on the side facing the ice 11. The guide wheel 8 and the driving wheel 9 are respectively connected to the bracket 7 through the connecting rod mechanism 13, and the shock absorbing spring 14 is arranged behind the connecting rod mechanism 13, and the shock absorbing simultaneously increases the obstacle-passing capability of the driving wheel 9 and the clamping wheel 10.

[0053] In one embodiment provided by the present invention, the guide cavity includes a first guide cavity 5 and a second guide cavity 6, and the first guide cavity 5 and the second guide cavity 6 are respectively arranged on both sides of the wire 4, and the first guide cavity 5 is close to the bracket 7, and the second guide cavity 6 is connected to the bracket 7 through the second telescopic rod 16. The first guide cavity 5 and the second guide cavity 6 are combined to form a guide cavity. The guide cavity wraps the wire to form an airflow channel, which prolongs the time for the airflow to heat the wire to improve the deicing efficiency. During the operation of the device, the second telescopic rod 16 is shortened, and the first guide cavity 5 and the second guide cavity 6 hug the wire to form an appropriate airflow channel to improve the deicing efficiency. When the device is online or offline, the second telescopic rod 16 is extended, and the device can be detached from the wire.

[0054] Of course, the number of guide cavities can be set as needed, and this embodiment will not be described in detail.

[0055] In one embodiment provided by the present invention, the device further comprises: a remote controller, which is in communication connection with the ice cutter, the burner 3, and the walking mechanism. The deicing device is operated by a drone, which remotely controls the upper and lower wires, and automatically moves along the wires to remove ice from the entire wire.

[0056] The hot ice melting wire deicing device provided in the embodiment of the present invention can cut off the ice ridges growing circumferentially on the wire 4 by an ice ridge cutter, and then use the fuel combustion in the burner 3 to generate a high-temperature airflow to spray the ice 11 on the wire 4, and the sprayed airflow flows along the guide cavity. The airflow continues to heat the ice 11 that is not completely melted, and the ice 11 is blown away by the airflow after melting, thereby achieving efficient deicing of the wire 4. Moreover, this device can de-ice without power outage, avoiding economic losses in the de-icing process.

[0057] Compared with the traditional DC ice melting method, this device can be put online through a drone during normal power supply to achieve efficient de-icing of power lines.

[0058] For ice-covered wires with a diameter of 5 cm, the hot-melt ice wire deicing device provided in the embodiment of the present invention can specifically have the following configuration. The device is composed of an ice cutter, a burner, a guide cavity, a walking mechanism, a battery fuel tank 17 and a bracket.

The power motor 1 adopts a 24V DC drive motor, and the blade 2 adopts a rotary blade, which rotates at high speed driven by the power motor 1. The cutter adopts one set, which is only installed directly above to cut off the ice ridges growing upward from the wire.

[0060] Burner 3 is a turbojet engine with a fuel consumption of 72g / min and a maximum thrust of 20N. After combustion, the airflow generated is about 400℃. It is installed directly above the wire, 10cm away from the wire, with an inclination angle of 45 degrees, and sprays backwards. After the airflow is sprayed to the wire, the temperature is about 150℃.

[0061] The flow guide cavity consists of two parts, namely the first flow guide cavity 5 and the second flow guide cavity 6. The first flow guide cavity 5 is 20 cm long, and the second flow guide cavity 6 is 25 cm long. The upper and second flow guide cavities are both semi-conical, and after merging, a conical channel is formed to wrap the wires, which prolongs the heating time of the turbojet engine's jet airflow on the wires, so as to improve the deicing efficiency.

[0062] The cutter, the burner and the guide cavity are all fixed on the bracket 7, driven by the traveling mechanism, and travel along the electric wires to achieve continuous deicing of the electric wires.

[0063] The walking mechanism is composed of a guide wheel 8 and a driving wheel 9. The guide wheel 8 is a hollow V-shaped wheel with a diameter of 10 cm, made of aluminum alloy, high temperature resistant, located at the front and having an obstacle crossing function. The purpose of hollowing is to reduce the weight of the guide wheel.

[0064] The driving wheel 9 is also a hollow V-shaped wheel with a diameter of 5.5 cm and is covered with heat-resistant rubber to increase the contact friction between the driving wheel and the wire. Two clamping wheels 10 are installed under the driving wheel. The clamping wheels 10 are arranged one in front of the other behind the driving wheel. After forming a wheel set with the driving wheel 9, they are close to the de-iced wire 4. The diameter of the clamping wheel 10 is 2-3 cm.

[0065] The driving wheel 9 is connected to the driving motor 12, which is a DC reduction motor with a reduction ratio of 5 to 200 to provide sufficient driving force. The driving motor 12 is connected to the driving wheel 9 shaft.

[0066] The distance between the guide wheel 8 and the driving wheel 9 is 20-100 cm.

[0067] The guide wheel 8 and the driving wheel 9 are connected to the bracket 7 through a connecting rod mechanism 13, and a shock absorbing spring 14 is arranged behind the connecting rod mechanism 13 to reduce the shock and increase the obstacle-passing ability of the driving wheel 9 and the clamping wheel 10. The length of the shock absorbing spring 14 is 10-30 cm.

[0068] The clamping wheel 10 is connected to the bracket 7 via a first telescopic rod 15. The second flow guide cavity 6 is connected to the bracket 7 via a second telescopic rod 16.

[0069] A battery fuel tank 17 is arranged under the electric wire to contain the fuel required by the burner 3 and the power required by the power motor 1 and the drive motor 12. The battery fuel tank 17 is connected to the bracket 7, and a rotating mechanism 18 is arranged at the connection to ensure that the device does not tip over when walking up and down the slope.

[0070] The motor, turbojet engine start / stop, and speed are all adjusted wirelessly via the remote control.

[0071] Before operation, the first telescopic rod 15 and the second telescopic rod 16 are in an extended state, and the device is hoisted onto the wire by a drone, and the turbojet engine is started to clear the ice-covered wires by 0.5 meters. Then the device is placed on the wire, and the first telescopic rod 15 and the second telescopic rod 16 are retracted to hold the wire tightly, and the equipment is put online.

[0072] The turbojet engine is continuously turned on to melt and de-ice the ice on the wires. The driving wheel 9 is driven by the driving motor 12 to move forward according to the ice melting speed to achieve continuous de-icing of the wires.

[0073] After the de-icing is completed, the device is hoisted by the drone, the first telescopic rod 15 and the second telescopic rod 16 are extended, and the device leaves the electric wire and returns to the ground.

[0074] The de-icer battery is a lithium-ion battery.

[0075] The deicing device is loaded with 10kg of fuel and can de-ice 1km of wires at a time. 9. The de-icing device for hot melting wires according to claim 1,

[0077] 201. Start the ice cutter to cut off the ice on the electric wire 4.

[0078] First, deal with large ice ridges or solid ice layers on the wire, which may be difficult to melt directly by high temperature and may hinder the efficiency or safety of subsequent thermal melting steps.

[0079] 202. Start the burner 3. The high-temperature airflow generated by the burner 3 is sprayed on the ice 11 on the wire 4 to melt the ice 11. Moreover, the sprayed airflow flows along the guide cavity. The airflow continuously heats the incompletely melted ice 11 and blows away the moisture formed after the ice 11 melts.

[0080] The high-temperature airflow generated by the burner is used to directly heat the ice on the wires, causing them to melt quickly.

[0081] Through the design of the guide cavity, the jet airflow can not only melt the ice, but also effectively blow away the melted water to prevent re-freezing.

[0083] While melting the ice, the de-icing device can automatically move along the wires to achieve continuous de-icing of the entire wire.

[0084] Specifically, adjust the walking speed and direction in time according to the actual conditions of the wires, such as slope, curvature, etc.

[0085] The hot ice melting wire deicing method provided in the embodiment of the present invention can cut off the ice ridges growing circumferentially on the wire 4 by an ice ridge cutter, and then use the fuel combustion in the burner 3 to generate a high-temperature airflow to spray the ice 11 on the wire 4, and the sprayed airflow flows along the guide cavity. The airflow continues to heat the ice 11 that is not completely melted, and the ice 11 is blown away by the airflow after melting, thereby achieving efficient deicing of the wire 4. Moreover, this device can de-ice without power outage, avoiding economic losses in the de-icing process.
