[0025] The present invention will be described in more detail with reference to the accompanying drawings as follows:

[0026] Combined with Figures 1-10 , a de-icing power device for high-voltage wires based on the cooperation of thermal and mechanical forces of the present invention includes a box body, the box body includes a box cover 1 and a box body main body 2, the box cover 1 includes a through hole 101 and a reserved hole 102, and the box body main body 2 includes a box body shell 21, a single-chip microcomputer controller 22, an air inlet filter screen 23, a battery 24, a generator 25, a coupling 26 and a micro gas turbine 27.

[0027] The box body shell includes an exhaust pipe inlet 201, a gas turbine fixed platform 202, a gas turbine fixing frame 203, a generator fixed platform 204, a controller fixing hole 205, an air inlet 206, an exhaust pipe 207, an exhaust pipe outlet 208 and a box cover fixing point 209.

[0028] The exhaust pipe inlet 201 is located inside the middle section of the box body main body 2, and is connected to the gas turbine exhaust port 272 by a flange thereon. The exhaust pipe 207 is fixed on the outer side of the box body wall, is a semi-circular pipe, and is symmetrically distributed. The two side pipes converge to the exhaust pipe outlet 208. The exhaust pipe outlet 208 is in a contracted shape in the outlet section. The controller fixing hole 205 is a threaded hole and is fixedly connected to the corresponding connection point on the single-chip microcomputer controller 22. The box cover fixing point 209 is a threaded hole and is correspondingly matched with the through hole 101 on the box cover 1. The gas turbine fixed platform 202 is fixed inside the box body 2 and is mutually matched with the gas turbine fixing plate 275. The air inlet 206 is a circular hole opened on the end face of the box body main body, and its position is set in the opposite direction to the gas turbine air inlet 271. The gas turbine fixing frame 203 is a flange ring, and the gas turbine is fixed after passing through this part.

[0029] The micro gas turbine 27 includes a gas turbine air inlet 271, a gas turbine exhaust port 272, a gas turbine connection port 273, a gas turbine output shaft 274 and a gas turbine fixing plate 275.

[0030] The power source of the device adopts the micro gas turbine 27, and the gas turbine output shaft 274 is connected to the generator 25 by the coupling 26 to drive the traveling mechanism and other additional mechanisms.

[0031] When the gas turbine 27 exhausts, the waste heat gas converges through the exhaust pipe 207, and the exhaust pipe outlet 208 is directly facing the wire and cable icing, and the recovered waste heat is used for hot gas de-icing.

[0032] The gas turbine 27 adopts symmetric exhaust on both sides, and the exhaust gas is converged through the exhaust pipe 207 to form a strong disturbance, enhancing the heat exchange efficiency.

[0033] An air inlet filter screen 23 is adopted at the air inlet 206 to exclude the redundant ice-melting water in the box while ensuring air intake filtration.

[0034] The air inlet 206 is symmetrical with the exhaust port 208 of the gas turbine, ensuring that the cool air entering will cool the generator 25 and the gas turbine 27, while increasing the intake air temperature, playing the role of intake air waste heat, and increasing the thermal efficiency.

[0035] A reserved hole 102 is provided on the box cover 1 to ensure the addition of the traveling mechanism and additional mechanisms, achieving a modular effect.

[0036] The box cover 1 includes a through hole 101, which corresponds to the box cover fixing point 209. The box cover fixing point 209 is a threaded hole. The box body 2 includes a single-chip microcomputer controller 22, and the single-chip microcomputer controller 22 is fixedly connected to the controller fixing point 205. The air inlet filter screen 23 is fixedly installed on the air inlet 206. The generator 25 is fixedly installed on the generator fixing platform 204. The gas turbine 27 includes a gas turbine fixing plate 275, and is fixedly connected through the gas turbine fixing plate 275 and the gas turbine fixing platform 202. The gas turbine output shaft 274 is connected to the generator 25 through a coupling 26. The gas turbine 27 works to drive the generator 25 to generate electricity. The box body shell includes an exhaust pipe 207, and the exhaust pipe 207 is fixed on the periphery of the box body wall. The exhaust pipe inlet 201 is fixedly connected to the gas turbine exhaust port 272. After the gas turbine 27 works, the waste heat exhaust gas flowing out through the gas turbine exhaust port 272 enters the exhaust pipe 207, and finally converges to the exhaust pipe outlet 208 to utilize the waste heat of the tail gas for thermal de-icing.

[0037] The exhaust pipe inlet 201 is located inside the middle section of the box body 2, and is fixedly connected to the gas turbine exhaust port 272 with a flange. The exhaust pipe 207 is fixed on the outer side of the box body wall, is a semi-circular pipe, and is symmetrically distributed. The two-side pipes converge to the exhaust pipe outlet 208. The exhaust pipe outlet 208 is in a contracted shape in the outlet section, increasing the flow rate and heat conduction rate during exhaust.

[0038] By adjusting the power of the gas turbine 27, the temperature and flow rate of the outlet exhaust gas are changed to adapt to different thicknesses of cables and different thicknesses of ice coatings.

[0039] The controller fixing hole 205 is a threaded hole and is fixedly connected to the corresponding connection point on the microcontroller 22. The box cover fixing point 209 is a threaded hole and is correspondingly matched with the through hole 101 on the box body cover 1. The gas turbine fixing platform 202 is fixed inside the box body 2 and cooperates with the gas turbine fixing plate 275. The air inlet 206 is a circular hole opened on the end face of the box body main body, and its position is set in the opposite direction to the gas turbine air inlet 271. The gas turbine fixing frame 203 is a flange ring, and the gas turbine is fixed after passing through this part.

[0040] The microcontroller 22 is connected to the gas turbine connection port 273 and the battery 24, and the adjustable power condition of the gas turbine is controlled by controlling the microcontroller 22.

[0041] The reserved hole 102 is arranged on the box body cover 1. The reserved hole 102 is a through hole, and the microcontroller 22 can connect additional devices, such as measuring devices, traveling mechanisms, etc., through the reserved hole 102, which is convenient for equipment expansion.

[0042] During de-icing, first, the device is fixed on the cable through the traveling mechanism, and then the microcontroller 22 controls the gas turbine 27 to start. The output shaft 274 of the gas turbine is connected to the generator 25 through the coupling 26 to drive the traveling mechanism to move forward. During the operation of the gas turbine 27, the outside cold air is filtered through the air inlet filter screen 23 and then enters the box body. After passing through the high-temperature outer surfaces of the generator 25 and the gas turbine 27, it plays a cooling role and at the same time takes in the waste heat. After the gas turbine 27 does work, the remaining exhaust gas enters the exhaust pipe 207 through the gas turbine exhaust port 272, and is gathered together under the guidance of the symmetrically distributed exhaust pipes 207. At the outlet section 208 of the exhaust pipe, it accelerates due to the reduction of the pipe diameter and is finally sprayed onto the ice-covered surface. As the equipment moves forward continuously, the melted ice water enters the box body and is discharged along the air inlet 206, thus completing the entire process of power supply and de-icing using the waste heat of the exhaust gas.

[0043] Through the setting of the controller, the present invention automatically conducts continuous thermal de-icing on the high-voltage cable. The whole process is simple and safe to operate. The thermal energy is used to remove the ice covering the cable, replacing other de-icing methods, reducing manpower consumption and energy consumption, and improving the de-icing efficiency and stability.
