Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0030] Please refer to Figures 1-5 The utility model provides a kind of overhead line deicing device, including connecting plate 1.

[0031] Refer to Figure 1 , Figure 3 and Figure 5 The top end of connecting plate 1 is fixed with adjusting structure 5, adjusting structure 5 includes adjusting seat 51 fixed to the top end of connecting plate 1, adjusting block 52 is arranged on both sides in adjusting seat 51, screw rod 53 is screw-connected in the inside of adjusting block 52, guide rod 54 is arranged on both sides of screw rod 53, adjusting structure 5 further includes servo motor 55 fixedly installed on one side of connecting plate 1, limiting frame 56 is fixed to the top end of adjusting block 52, the thread direction of both ends of screw rod 53 is opposite, one end of screw rod 53 extends to the inside of adjusting seat 51 and is rotationally connected with adjusting seat 51, the other end of screw rod 53 extends to the outside of adjusting seat 51 and is fixedly connected with the output end of servo motor 55, limiting frame 56 is distributed symmetrically on both sides of line body 3.

[0032] Under the power supply of battery 6, start servo motor 55, servo motor 55 rotation will drive screw rod 53 to rotate, screw rod 53 rotation will drive adjusting block 52 to move in the inside of adjusting seat 51, because the thread direction of both ends of screw rod 53 is opposite, so that both sides adjusting block 52 synchronously moves towards or reversely, to adjust the distance of limiting frame 56, when adjusting block 52 moves mutually close, the distance between deicing blade 45 can be shortened, to deice line with smaller diameter, when adjusting block 52 moves mutually far away, the distance between deicing blade 45 can be increased, to deice line with larger diameter, guide rod 54 can play auxiliary role, to increase the stability of adjusting block 52 when moving.

[0033] Refer toFigure 1 、 Figure 3 and Figure 4 The inner side wall of the limiting frame 56 is fixed with the deicing structure 4, which comprises a heating seat 41, a heating cavity 42, a heating wire 43, a heat-conducting plate 44 and a deicing blade 45.

The heating wire 43 generates heat, which is transmitted to the deicing blade 45 through the heat-conducting plate 44. The temperature of the heated deicing blade 45 is increased. When the deicing blade 45 contacts with the ice layer, the ice layer is quickly melted, the adhesion between the ice layer and the line body 3 is reduced, the deicing blade 45 is more easily scraped off the ice, the deicing speed is increased, and the temperature sensor 7 is fixed on the inner wall of the heat-conducting plate 44. When the temperature of the heat-conducting plate 44 continuously increases to the preset value of the temperature sensor 7, the temperature sensor 7 controls the heating wire 43 to stop heating through the single-chip microcomputer in the temperature sensor 7. When the temperature of the heat-conducting plate 44 is too low and lower than the preset value of the temperature sensor 7, the temperature sensor 7 controls the heating wire 43 to open through the single-chip microcomputer in the temperature sensor 7. The preset value of the temperature sensor 7 is the upper limit of 50°C and the lower limit of 30°C. When the temperature exceeds the range, the single-chip microcomputer cuts off or starts the heating wire 43.
