In the ice-covered area, the static contact is installed on the conductor, which is prone to ice accumulation and causes the closing failure.

[0003] Currently, the static contacts can be fully enclosed for protection by installing bell-type or canopy-type protective measures, but these protective measures cannot prevent the static contacts from being covered with ice due to prolonged freezing rain.

[0033] Example 1

[0034] Please see the attached Figure 1 In this embodiment, a de-icing device for a static contact (hereinafter referred to as the "device") includes: an ice-breaking contact 200, a driving assembly, an ice-melting contact 300, a monitoring assembly 400 and a telescopic rod 100; the ice-breaking contact 200 is arranged at one end of the telescopic rod 100; the driving assembly is arranged at the other end of the telescopic rod 100, for driving the telescopic rod 100 to extend and retract; the ice-melting contact 300 is arranged at one end of the telescopic rod 100 close to the ice-breaking contact 200, and the ice-melting contact 300 can be electrically connected to the static contact 10 to melt the ice on the surface of the static contact 10; the monitoring assembly 400 is arranged at one end of the telescopic rod 100 close to the ice-breaking contact 200, and the monitoring assembly 400 includes a temperature monitoring device and a camera, for monitoring the temperature of the melting ice on the static contact 10.

[0035] Please see the attached Figure 2 In this embodiment, the ice-breaking contact 200 is first adjusted relative to the static contact 10, and the telescopic rod 100 is driven to extend and retract at a certain frequency by the driving component, so that the ice-breaking contact 200 clears the larger ice on the static contact 10 at a certain frequency.

[0036] Please see the attached Figure 3 In this embodiment, the ice-melting contact 300 can also be placed opposite to the static contact 10, and the ice-melting contact 300 can be electrically connected to the static contact 10 through a driving component, and the ice on the static contact can be melted by the thermal effect after power is turned on, thereby completing a thorough de-icing operation.

[0037] Furthermore, in this embodiment, a monitoring component 400 is also provided. The temperature monitoring device of the monitoring component can detect the real-time temperature of the melting of the ice-covered area during the ice melting process; the melting conditions of the ice-covered area of ​​the static contact are collected through the camera of the detection component, thereby improving the operator's monitoring ability of the de-icing process of the static contact 10.

[0038] Optionally, a hammer head is provided at one end of the ice-breaking contact 200 away from the telescopic rod 100. In this embodiment, the hammer head is a metal hammer head with high strength and hardness and an anti-corrosion coating. The hammer head is driven by the telescopic rod 100 to hammer the ice back and forth, so that larger ice is broken and removed.

[0039] The hammer head is preferably provided with a plurality of spike structures on its surface to further enhance the mechanical deicing effect. The plurality of spike structures are provided on the front end of the hammer head's working surface. These spike structures can more easily penetrate the interior of the ice, breaking it up internally. This avoids direct hammering of the ice and the resulting splashing of ice fragments, thus improving the safety of the power grid deicing work area.

[0040] Optionally, the temperature monitoring device is an infrared temperature sensor. The infrared temperature sensor can effectively achieve isolated temperature measurement. Specifically, by setting the infrared temperature sensor at a certain distance, the ice melting temperature of the ice-covered area can be measured to monitor the ice melting process.

[0041] Please refer to the attached Figure 1 -Attached Figure 3 In this embodiment, the device also includes a fixing base 500, wherein the ice-breaking contact 200, the ice-melting contact 300 and the monitoring component 400 are all fixed on the fixing base 500, and the fixing base 500 is connected to the end of the telescopic rod 100 away from the driving component 300. The fixing base 500 can effectively ensure that the ice-breaking contact 200, the ice-melting contact 300 and the monitoring component 400 are integrated into one, thereby simplifying the structure of the entire device. Specifically, the ice-breaking contact 200, the ice-melting contact 300 and the monitoring component 400 can be connected to the fixing base 500 by snapping, riveting or screwing. Those skilled in the art will understand that in the connection method of the ice-breaking contact 200, the ice-melting contact 300 and the monitoring component 400 to the fixing base 500, it is only necessary to ensure that the fixation is reliable and stable. In this embodiment, the connection form is not listed in detail.

[0042] In this embodiment, an overhead ground connection terminal 40 is further provided on the fixing base 500 for grounding.

[0043] Optionally, the device further includes an insulating rod 600, through which the fixing base 500 is connected to the telescopic rod 100. The provision of the insulating rod 600 between the fixing base 500 and the telescopic rod 100 ensures electrical insulation between the working end and the driving end of the device. Because the working end of the device is also provided with an ice-melting contact 300, which connects to the static contact 10 during operation and energizes it, if a leakage occurs at the working end, the insulating rod 600 can prevent the rear-end driving assembly from being affected by other abnormal currents.

[0044] Optionally, the stationary contact 10 is provided with a connection hole, into which the ice-melting contact 300 can be inserted and electrically connected. Preferably, to ensure connection reliability, a latching protrusion is provided within the connection hole, and a latching slot is provided on the ice-melting contact 300. The connection between the latching protrusion and the latching slot ensures reliable electrical connection between the two.

[0045] Preferably, the static contact 10 is a copper tube suitable for inserting the ice-melting contact 300 .

[0046] In this embodiment, the static contact 10 is connected to the triangular bracket 20 and is electrically connected to the wire 30 .

[0047] Please refer to the attached Figure 1 In this embodiment, the end of the telescopic rod 100 away from the ice-breaking contact 200 is hinged to the mounting bracket 700. The telescopic rod 100 can rotate about the hinge axis 710 to direct the ice-breaking contact 200 or the ice-melting contact 300 toward the stationary contact 10. By adjusting the telescopic rod 100 to rotate about the hinge axis 710 to a certain angle, the ice-breaking contact 200 or the ice-melting contact 300 can be directed toward the stationary contact 10, thereby conveniently adjusting the position of the ice-breaking contact 200 or the ice-melting contact 300.

[0048] Optionally, the drive assembly is disposed on the mounting bracket 700 .

[0049] One end of the support rod 800 away from the telescopic rod 100 is hinged to the auxiliary telescopic rod 900. The driving assembly can drive the auxiliary telescopic rod 900 to extend and retract. The auxiliary telescopic rod 900 is passed through the connecting end 910. The support rod 800 is rotated through the auxiliary telescopic rod 900, so that the ice-breaking contact 200 or the ice-melting contact 300 is directed toward the static contact 10.

[0050] Example 2

[0051] This embodiment has essentially the same structure as the first embodiment, differing in that an ice-breaking blade is provided on the end of the ice-breaking contact 200 away from the telescopic rod 100. The ice-breaking blade has multiple layers of blades. This prevents ice fragments from being splashed by hammering, and the multiple layers of blades also improve the efficiency of mechanical deicing.

[0052] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
