[0031] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0032] Embodiment 1:

[0033] Please refer to Figure 1-Figure 7An anti-icing device includes an installation box 1, which is installed on a contact network bracket. The end of the installation box 1 close to the contact line is fixedly connected to a hollow rod 2, the installation box 1 and the hollow rod 2 are connected, the end of the hollow rod 2 away from the installation box 1 is fixedly connected to a first clamping plate 3, the end of the first clamping plate 3 away from the hollow rod 2 is rotatably connected to a second clamping plate 4, and the second clamping plate 4 and the first clamping plate 3 are arranged to wrap the outside of the contact line, the bottom of the first clamping plate 3 and the second clamping plate 4 are retracted, a vibration component 5 is arranged inside the installation box 1 and the hollow rod 2, and a protection component 6 is arranged inside the first clamping plate 3.

[0034] When in use, the installation box 1 is installed on the contact network bracket, and then the first clamping plate 3 is attached to one side of the contact line, and the second clamping plate 4 is buckled. The bottom of the contact line can be wrapped by setting the first clamping plate 3 and the second clamping plate 4 to be retractable at the bottom;

[0035] When ice condenses on the outside of the contact line, the vibration assembly 5 can be turned on to generate knocking and vibration, and the vibration effect can be transmitted to the first clamping plate 3 and the second clamping plate 4, so that the first clamping plate 3 and the second clamping plate 4 on the outside of the contact line can be wrapped to achieve the effect of vibration anti-icing on the contact line;

[0036] At the same time, by providing the protection component 6, when the first clamping plate 3 and the second clamping plate 4 vibrate the contact line, the outer side of the contact line can be protected, thereby increasing the service life of the contact line.

[0037] The vibration assembly 5 includes a motor 7, a rotating rod 8, a driving disk 9 and a driving column 10. The motor 7 is fixedly connected to the inner side of the installation box 1, the output end of the motor 7 close to the hollow rod 2 is fixedly connected to the rotating rod 8, the driving disk 9 is fixedly connected to the outer side of the rotating rod 8, and a plurality of driving columns 10 are symmetrically arranged and fixedly connected to the outer side of the driving disk 9.

[0038] The vibration assembly 5 also includes a hollow fixed block 11 and a transmission rod 12. A plurality of hollow fixed blocks 11 are fixedly connected to the inner side of the hollow rod 2 near one end of the first clamping plate 3. A transmission rod 12 is arranged on the inner side of the hollow rod 2 near one end of the first clamping plate 3, and the outer side of the transmission rod 12 is clearance-fitted with the inner side of the plurality of hollow fixed blocks 11.

[0039] The vibration assembly 5 also includes a connecting rod 13, a fixing hook 14, a fixing plate 15 and a first spring 16. A connecting rod 13 is arranged on the inner side of one end of the hollow rod 2 close to the installation box 1. The end of the connecting rod 13 close to the installation box 1 extends to the inner side of the installation box 1 and is fixedly connected with the fixing hook 14. The fixing hook 14 and the driving column 10 are arranged with clearance fit. A fixing plate 15 is fixedly connected to the outer side of the connecting rod 13. The outer peripheral side of the fixing plate 15 is fixedly connected with multiple first springs 16 in a circular array. The end of the first spring 16 away from the fixing plate 15 is fixedly connected to the inner wall of the hollow rod 2.

[0040] The vibration assembly 5 also includes a knocking plate 17 and a second spring 18. The end of the connecting rod 13 close to the transmission rod 12 is fixedly connected to the knocking plate 17. A plurality of second springs 18 are fixedly connected to the outer peripheral side of the knocking plate 17 in a circular array. The end of the second spring 18 away from the knocking plate 17 is fixedly connected to the inner wall of the hollow rod 2, and the second spring 18 and the transmission rod 12 are extrusion-fitted.

[0041] The protection assembly 6 includes a cushion block 19. A reserved groove is provided on the inner top of the first clamping plate 3. The cushion block 19 is fixedly connected to the inner side of the reserved groove, and the cushion block 19 is fitted to the top of the contact line.

[0042] Specifically: by turning on the motor 7, the motor 7 drives the rotating rod 8 to rotate, thereby driving the driving plate 9 fixedly connected to the rotating rod 8 to rotate, thereby driving the driving column 10 outside the driving plate 9 to move. When the driving plate 9 drives the driving column 10 to move, the driving column 10 can pass through the bottom of the fixed hook 14;

[0043] When the driving column 10 moves to the inner side of the bottom of the fixing hook 14, the fixing hook 14 can be matched with the driving column 10 through the clearance, and the fixing hook 14 can be driven by the driving column 10 to move away from the first clamping plate 3. At this time, the fixing hook 14 can produce a pulling effect on the connecting rod 13 inside the hollow rod 2;

[0044] When the connecting rod 13 moves toward one end close to the installation box 1, the fixing plate 15 and the knocking plate 17 fixedly connected to the outside of the connecting rod 13 can be driven to move toward one end close to the installation box 1 at the same time. At this time, the knocking plate 17 will be away from the end of the transmission rod 12. When the fixing plate 15 and the knocking plate 17 are driven by the connecting rod 13, the first spring 16 on the outside of the fixing plate 15 and the second spring 18 on the outside of the knocking plate 17 can simultaneously produce a pulling effect, and the first spring 16 and the second spring 18 can produce a stretching effect.

[0045] When the driving plate 9 continues to drive the driving column 10 to move, and the driving column 10 moves out of the clearance fit range of the fixing hook 14, the fixing hook 14 will lose the driving effect of the driving column 10, and cancel the driving effect on the connecting rod 13. At the same time, through the elastic setting of the first spring 16 and the second spring 18, the connecting rod 13, the fixing plate 15 and the knocking plate 17 can be driven to synchronously approach the end of the transmission rod 12 away from the first clamping plate 3. At this time, the knocking plate 17 will collide with the end of the transmission rod 12 away from the first clamping plate 3;

[0046] At the same time, by setting the transmission rod 12, the vibration effect generated by the impact of the knocking plate 17 on the transmission rod 12 can be transmitted to the inner side of the first clamping plate 3 and the inner side of the second clamping plate 4. At the same time, by the wrapping setting of the first clamping plate 3 and the second clamping plate 4 on the contact line, the ice on the outer side of the contact line can be vibrated and dropped.

[0047] At the same time, by providing the pad 19, the damage to the contact line caused by long-term vibration can be reduced, thereby increasing the service life of the contact line.
