Description

Technical Field

[0001] This invention relates to the field of power transmission technology, and in particular to a multi-mode ground wire de-icing device. Background Technology

[0002] In power transmission systems, the ground wires of transmission lines are highly susceptible to icing under severe weather conditions such as low temperatures, rain, snow, and heavy fog. Icing on the ground wires significantly increases the line load, leading to frequent serious accidents such as tower tilting and collapse, and conductor breakage. It also interferes with communication and line protection functions, potentially causing large-scale power outages and seriously threatening the safe and stable operation of the power system.

[0003] Currently, mechanical de-icing or thermal de-icing can be used. Mechanical de-icing specifically refers to the direct breaking and removal of ice by manually striking it with tools or operating simple mechanical devices. For example, workers use hammers or other tools to strike the iced ground wire, causing the ice to fall off. The problems with this method are: extremely low efficiency, requiring a large amount of manpower, and extremely high labor intensity. Furthermore, operating in dangerous environments such as at heights poses serious safety hazards and can easily cause personal injury to operators.

[0004] Thermal de-icing refers to melting ice by passing electricity through a ground wire and relying on the heat generated by the current. A common method involves using a specific power supply connected to the ground wire, allowing current to flow through the ground wire and generate heat to melt the ice. However, existing thermal de-icing devices suffer from poor stability when connected to the ground wire, easily leading to poor contact and affecting de-icing efficiency. Furthermore, this method has poor adaptability and struggles to operate stably under various complex conditions, such as in severe weather or different terrains, resulting in significant fluctuations in de-icing effectiveness.

[0031] like Figures 1 to 4 As shown, the present invention provides a multi-mode grounding wire de-icing device, comprising: An automatic retraction structure hanging point device 1 is installed at the end of the ground wire 100. The automatic retraction structure hanging point device 1 includes a ground wire retraction power structure connected to the iron tower 200 and a connection structure that can be insulatedly connected to the end of the ground wire 100. The ground wire retraction power structure retracts and releases the ground wire 100 through the connection structure to generate displacement fluctuations to break the ice covering the ground wire. The ground lead connector assembly 3 includes a connector power structure, a rotating contact assembly 4, a contact finger assembly 5, and a lead wire 7. The contact finger assembly 5 is electrically connected to the ground wire 100. The rotating contact assembly 4 can rotate away from the contact finger assembly 5 under the drive of the connector power structure (e.g., ...). Figure 1 Rotary contact assembly 4 on the left side of the tower or rotary electrical contact finger assembly 5 (such as...) Figure 1 The rotating contact assembly 4 on the right side of the tower is connected to an external power supply via a down conductor 7. When the rotating contact assembly 4 is electrically connected to the contact finger assembly 5, the current forms a circuit through the down conductor 7, the rotating contact assembly 4, the contact finger assembly 5, and the ground wire 100, causing the ground wire 100 to heat up and melt ice.

[0032] In the multi-mode ground wire de-icing device of the present invention, the automatic retraction structure hanging point device 1 generates displacement fluctuations by tightening or releasing the ground wire, breaking the ice on the ground wire; the ground wire lead connector device 3 heats up the ground wire and melts the ice by connecting to an external power source; the two de-icing modes work together to cope with various complex working conditions, whether it is thin ice, thick ice, or special cases such as hard ice, it can effectively remove ice.

[0033] Furthermore, such as Figure 1 , Figure 2 As shown, the multi-mode ground wire de-icing device of the present invention also includes a ground wire insulator string structure 2. The first end of the ground wire insulator string structure 2 is insulated and connected to the connection structure of the automatic retraction structure hanging point device 1. The second end of the ground wire insulator string structure 2 is electrically connected to the end of the ground wire 100. The ground wire insulator string structure 2 is electrically connected to the contact finger assembly 5 and the ground wire 100. The ground wire insulator string structure 2 provides electrical insulation between the ground wire 100 and the automatic retraction structure hanging point device 1.

[0034] Furthermore, the multi-mode ground wire de-icing device of the present invention also includes a control system, which includes sensors and controllers. The sensors are used to monitor and detect the icing parameters of the ground wire 100, including icing thickness, tension, etc. The controllers include a first controller and a second controller. The first controller is electrically connected to and controls the ground wire retraction and extension power structure, and the second controller is electrically connected to and controls the connector power structure.

[0035] Furthermore, such as Figure 1 , Figure 2 , Figure 3 As shown, the automatic retraction and deployment structure hanging point device 1 also includes a tower connector 12. The ground wire retraction and deployment power structure includes a first drive motor 10 and a first transmission mechanism 11. The first drive motor 10 is connected to the iron tower 200 through the tower connector 12, and the first controller is set on the first drive motor 10. The connection structure includes a telescopic connecting rope 13, which is connected to the ground wire insulator string structure 2 through the ground wire string connection end 14. The first drive motor retracts and deploys the ground wire 100 through the first transmission mechanism 11, the telescopic connecting rope 13, the ground wire string connection end 14, and the ground wire insulator string structure 2.

[0036] The first drive motor 10 drives the first transmission mechanism 11 to move, adjusting the displacement of the telescopic connecting rope 13, thereby achieving free and precise adjustment of the length displacement of the ground wire insulator string structure 2. During de-icing, the ground wire insulator string structure 2 is tightened or released by the telescopic connecting rope 13, causing displacement fluctuations in the ground wire (this displacement value is a micro-displacement, not a large displacement that can damage the ground wire itself), breaking the ground wire 100 and causing it to become covered with ice.

[0037] Furthermore, such as Figure 1 , Figure 2 As shown, the ground wire insulator string structure 2 is a dedicated insulator string structure, including a ground wire insulator 22, an insulator connection end 21, and a conductive connector 23 (connecting hardware). The first end of the ground wire insulator 22 is connected to the connection structure of the automatic retraction structure hanging point device 1 through the insulator connection end 21, and the second end of the ground wire insulator 22 is electrically connected to the ground wire 100 through the conductive connector 23. The top of the contact finger assembly 5 is electrically connected between the ground wire insulator 22 and the conductive connector 23. The ground wire and the contact finger connecting lead 25 are electrically connected to the contact finger assembly 5. The ground wire and the contact finger connecting lead 25 are electrically connected to the ground wire 100 through the ground wire tension clamp 24.

[0038] Furthermore, such as Figure 1 , Figure 2 , Figure 4 , Figure 6As shown, the contact finger assembly 5 includes a contact finger 53, a contact finger support 52, and a contact finger protective cover 51. The top end of the contact finger support 52 is electrically connected between the ground wire insulator 22 and the conductive connector 23, and the bottom end of the contact finger support 52 is connected to the contact finger. The contact finger is covered by the contact finger protective cover 51. The two ends of the ground wire and contact finger connecting lead 25 are electrically connected to the contact finger and the ground wire tension clamp 24, respectively. Figure 5 As shown, contact finger 53 uses spring-loaded contact finger pieces, and several sets are typically designed according to the conduction requirements. The rotating contact 43 engages with the spring-loaded contact finger pieces, and the spring-loaded contact finger pieces achieve conductive connection through the clamping force of the spring. Through this design, the contact finger assembly 5 constitutes an elastic contact component.

[0039] Furthermore, the finger components 5 are spaced apart and electrically connected to the ground wire 100.

[0040] Furthermore, such as Figure 1 , Figure 4 As shown, the rotating contact assembly 4 includes a rotating contact 43, a contact conductive connector 41, and a rotating contact protective cover 42. The rotating contact protective cover 42 is connected to the tower 200 and is located on the side of the connector power structure away from the contact finger assembly 5. The rotating contact 43 can rotate to the contact finger assembly 5 to be electrically connected to the contact finger, or the rotating contact 43 can rotate to the rotating contact protective cover 42. The contact finger 53 is designed as an elastic structure to ensure a stable electrical connection between the rotating contact 43 and the contact finger 53. The rotating contact 43 is electrically connected to the lead wire 7 through the contact conductive connector 41.

[0041] Furthermore, such as Figure 1 , Figure 4 As shown, the connector power structure includes a second drive motor 30, a second transmission mechanism 31, and a rotating structure 33. The rotating contact assembly 4 is connected to the rotating structure 33. The second drive motor 30 is connected to the iron tower 200, and the second controller is set on the second drive motor 30. The second drive motor 30 drives the rotating contact assembly 4 to rotate through the second transmission mechanism 31 and the rotating structure 33. A connector insulation assembly 32 is provided between the second transmission mechanism 31 and the rotating contact assembly 4.

[0042] Furthermore, such as Figure 1 , Figure 4 As shown, the down conductor 7 is connected to the tower 200 via a down conductor insulation support clamp 6. The top end of the down conductor is electrically connected to the conductive connector 41, and the bottom end of the down conductor 7 is provided with an external power supply connection terminal 71, which is electrically connected to an external power source. The number of down conductor insulation support clamps 6 is determined according to the actual operating conditions. The down conductor insulation support clamps 6 prevent short circuits, effectively protect the line, and ensure the safe operation of the system.

[0043] Furthermore, such as Figure 1As shown, the control system includes a power signal line and a terminal operation device 9 installed at the bottom of the tower. The sensors and controllers are all connected to the power signal line and the terminal operation device 9 via signal lines 8.

[0044] The first controller controls the first drive motor 10 according to the program and detection data, intelligently adjusting the string length and controlling the ground wire displacement fluctuation. The ground wire retraction and extension power structure (electric transmission system) of the automatic retraction and extension structure hanging point device 1 can be intelligently adjusted according to the detection data to realize automated de-icing, reduce manual intervention, improve de-icing efficiency, and reduce manual labor intensity.

[0045] The second controller controls the second drive motor 30 according to the program and detection data, controls the position of the rotating contact 43, the rotating contact 43 rotates to the contact finger assembly 5 and is electrically connected to the contact finger, the current forms a circuit through the lead wire 7, the rotating contact assembly 4, the contact finger assembly 5 and the ground wire 100 to make the ground wire 100 heat up and melt ice.

[0046] Both the automatic retraction structure hanging point device 1 (first drive motor 10) and the ground wire lead connector device 3 (second drive motor 30) are equipped with signal lines 8, which connect to the power signal line and the terminal operation device 9 to realize monitoring and operation functions.

[0047] Example: The method of using the multi-mode grounding de-icing device of the present invention is as follows: In practical applications, the multi-mode grounding de-icing device is installed on the grounding tension tower (iron tower). During the non-icing season (when lightning protection grounding is required), the rotating contact 43 connects to the contact finger assembly 5, and the down conductor 7 connects the grounding wire 100 to the external power supply connection terminal 71. The grounding switch closes to ground the grounding wire 100 to the tower. During the icing season (when lightning protection grounding is not required), such as... Figure 1 As can be seen at the right tower 200, the rotating contact 43 is disconnected from the contact finger assembly 5 and placed inside the rotating contact protective cover 42 to prevent it from being covered by ice and snow.

[0048] When ice accumulates on ground wire 100, the sensor monitors parameters such as ice thickness and tension in real time and transmits them to the controller. If the ice is thin, the first controller drives the automatic retraction structure hanging point device 1 to slowly tighten the string length, using small ground wire displacement fluctuations to break the ice; if the ice is thick, the tightening force is increased to enhance the breaking effect.

[0049] If the automatic retraction structure hanging point device 1 fails to effectively remove ice or encounters special operating conditions, the ground wire down conductor connector device 3 is activated. The operator mates the rotating contact 43 with the contact finger assembly 5. The contact fingers are designed with an elastic structure to ensure a stable electrical connection. The down conductor 7 is connected to the external power supply connection terminal 71 at the bottom of the tower and connected to an external power source, causing the ground wire 100 to heat up and melt the ice. Throughout the entire de-icing process, the down conductor insulation support clamp 6 continuously provides insulation protection for the down conductor 7, ensuring the safe and stable operation of the system.

[0050] The above description is merely an illustrative embodiment of the present invention and is not intended to limit the scope of the invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention should fall within the scope of protection of the present invention.
