[0001] This utility model relates to the field of power line technology, and in particular to a DC de-icing fast short-circuiting device for power transmission lines. Background Technology

[0002] During the harsh winter, thick layers of ice easily form on the surface of power transmission lines. This ice not only significantly increases the vertical load on overhead conductors, but may also cause tower deformation, hardware damage, or even tower collapse. In the DC de-icing technology solution, workers need to transport the short-connected cables to the work site by high-altitude hoisting and install and connect multiple cables between overhead conductors using short-connection devices.

[0003] Existing DC de-icing short-circuit devices for transmission lines require the transmission line to be placed between an upper and lower connector, and bolts to be tightened to fix the connector to the transmission line surface. Operators need to carry tools to rotate the bolts when fixing and retracting the shorted cable, which is time-consuming and unsafe. Therefore, this solution proposes a rapid DC de-icing short-circuit device for transmission lines to solve the above problems. Utility Model Content

[0033] Example 1,

[0034] A DC de-icing fast short-circuit device for transmission lines, comprising:

[0035] Lower connector 1, with mounting bracket 9 fixedly installed on the upper surface of lower connector 1;

[0036] Upper connector 2 is located at the top of lower connector 1, and one end of upper connector 2 is hinged to lower connector 1; cable 6 is electrically connected to one of the reinforcing mechanisms.

[0037] It should be noted that one end of the lower connector 1 is hinged to one end of the upper connector 2. The hinge replaces the bolt fixation, reducing the operation time. The cable 6 is located at the bottom of the lower connector 1. The cable 6 is connected to the lower connector 1 through the reinforcement mechanism. The cable 6 transmits DC power to the short-circuit device to perform DC de-icing on the transmission line. When DC power is applied to the transmission line, the lower connector 1 is placed at the bottom of the transmission line, and the upper connector 2 is rotated to move the upper connector 2 to the top of the transmission line, thereby clamping and fixing it to the surface of the transmission line.

[0038] The reinforcement mechanism consists of multiple reinforcement mechanisms that are respectively connected to the lower connector 1 and the upper connector 2. The reinforcement mechanism is used to fix the power transmission line.

[0039] Specifically, the reinforcement mechanisms include:

[0040] Sliding rod 3, multiple sliding rods 3 are respectively inserted and connected to upper connector 2 and lower connector 1, and one end of one sliding rod 3 away from lower connector 1 is electrically connected to cable 6;

[0041] Support frame 4, multiple support frames 4 are disposed between upper receiving seat 2 and lower receiving seat 1, and the surfaces of multiple support frames 4 are respectively fixedly connected to multiple sliding rods 3;

[0042] It should be noted that one end of each of the multiple sliding rods is inserted and connected to the upper connector 2 and the lower connector 1 respectively. One end of the sliding rod away from the lower connector 1 is electrically connected to the cable 6. The support frame 4 is set between the upper connector 2 and the lower connector 1. The surfaces of the multiple support frames 4 are fixedly connected to the multiple sliding rods 3 respectively. When DC power is applied to the transmission line, the lower connector 1 is placed at the bottom of the transmission line, and the upper connector 2 is rotated to move the upper connector 2 to the top of the transmission line. The sliding rods 3 are moved to bring the support frames 4 closer to each other, thereby fixing the support frames 4 on the surface of the transmission line and supporting and fixing the transmission line. This allows the short-circuit device to be used for transmission lines of different sizes.

[0043] A clamping part is provided between the support frame 4 and the sliding rod 3, and the clamping part is used for the movement of the support frame 4 and the sliding rod 3.

[0044] Furthermore, the clamping part includes a first spring 5, one end of the plurality of first springs 5 ​​is fixedly connected to a plurality of support frames 4 respectively, the end of the plurality of first springs 5 ​​away from the support frame 4 is fixedly connected to the upper connecting seat 2 and the lower connecting seat 1 respectively, and the plurality of first springs 5 ​​are respectively sleeved on the outer wall of the plurality of sliding rods 3.

[0045] It should be noted that when DC power is applied to the transmission line, the lower connector 1 is placed at the bottom of the transmission line, and the upper connector 2 is rotated to move the upper connector 2 to the top of the transmission line. The sliding rod 3 is pushed to move by the elastic force of the first spring 5. The sliding rod 3 moves the support frame 4 closer to each other, thereby fixing the support frame 4 on the surface of the transmission line and supporting and fixing the transmission line. This method is applicable to transmission lines of different sizes.

[0046] Both the upper connector 2 and the lower connector 1 are fixedly installed with reinforcing plates 14, and multiple reinforcing plates 14 are used to reinforce the upper connector 2 and the lower connector 1.

[0047] It should be noted that multiple reinforcing plates 14 are respectively fixedly installed inside the upper connector 2 and the lower connector 1. The reinforcing plates 14 reinforce the upper connector 2 and the lower connector 1, improving their stability. In Embodiment 2, this utility model provides a fixing mechanism, applied to a DC de-icing quick short-circuit device for transmission lines in Embodiment 1. The fixing mechanism is located at one end of the lower connector 1 and is used to fix the upper connector 2 and the lower connector 1.

[0048] Specifically, fixed mechanisms include:

[0049] The fixing bracket 8 is fixedly installed on one end of the upper connector 2 near the mounting box;

[0050] The movable rod 7 has one end slidably installed in the mounting frame 9, and the end of the movable rod 7 away from the mounting frame 9 is inserted and connected to the fixed frame 8. A movable groove is provided on one side of the mounting frame 9.

[0051] A movable part is provided at one end of the movable rod 7, and the movable part is used to move the movable rod 7.

[0052] It should be noted that the fixed frame 8 and the mounting frame 9 are located on the same side. The movable rod 7 is slidably installed in the mounting frame 9. The end of the movable rod 7 away from the mounting frame 9 is inserted and connected to the fixed frame 8. When DC power is applied to the transmission line, the lower connector 1 is placed at the bottom of the transmission line, and the upper connector 2 is rotated to move the upper connector 2 to the top of the transmission line. The sliding rod 3 is pushed to move by the elastic force of the first spring 5. The sliding rod 3 moves the support frames 4 closer to each other, thereby fixing the support frames 4 on the surface of the transmission line and supporting and fixing the transmission line. The movable part moves the movable rod 7 into the mounting frame 9, and the fixed frame 8 is placed on both sides of the mounting frame 9. The movable part is released, and one end of the movable rod 7 moves into the fixed frame 8 and is inserted and connected to the fixed frame 8 to fix the upper connector 2 and the lower connector 1. The shorting device can be quickly disassembled and installed, reducing the time spent working at height and increasing construction safety.

[0053] Specifically, the moving part includes a push plate 10, one end of which is fixedly connected to the moving rod 7, and the end of the push plate 10 away from the moving rod 7 extends out of the moving groove;

[0054] It should be noted that one end of the push rod passes through the moving slot, and the other end of the push rod is fixedly connected to the moving rod 7. When DC power is applied to the transmission line, the lower connector 1 is placed at the bottom of the transmission line, and the upper connector 2 is rotated to move the upper connector 2 to the top of the transmission line. Through the elastic force of the first spring 5, the sliding rod 3 is pushed to move. The movement of the sliding rod 3 causes the support frame 4 to move closer to each other, thereby fixing the support frame 4 on the surface of the transmission line and supporting and fixing the transmission line. Pushing the push rod causes the push rods to move closer to each other, thereby moving the moving rod 7 into the mounting frame 9. The fixing frame 8 is placed on both sides of the mounting frame 9. The push plate 10 is released, and one end of the moving rod 7 moves into the fixing frame 8 and is inserted and connected to the fixing frame 8 to fix the upper connector 2 and the lower connector 1. This allows for quick disassembly and installation of the short-connection device, reducing the time spent working at height and increasing construction safety.

[0055] A fixing plate 11 is fixedly installed inside the mounting bracket 9. The fixing plate 11 is inserted and connected to the moving rod 7. A second spring 12 is sleeved on the outer wall of the end of the moving rod 7 away from the fixing bracket 8. One end of the second spring 12 is fixedly connected to the fixing plate 11. An installation plate 13 is fixedly sleeved on the outer wall of the moving rod 7. The installation plate 13 is slidably connected to the inner wall of the mounting bracket 9. The end of the installation plate 13 near the fixing plate 11 is fixedly connected to the other end of the second spring 12.

[0056] It should be noted that the fixing plate 11 is set inside the mounting frame 9, and the fixing plate 11 is fixedly connected to the inner wall of the mounting frame 9. The fixing plate 11 is inserted and connected to one end of the moving rod 7. A second spring 12 is fixedly installed on the end of the fixing rod near the moving rod 7. The second spring 12 is sleeved on the outer wall of the moving rod 7. The mounting plate 13 is fixedly sleeved on the end of the moving rod 7 near the fixing plate 11. The mounting plate 13 is slidably connected to the inner wall of the mounting frame 9. The end of the mounting plate 13 near the fixing plate 11 is fixedly connected to the end of the second spring 12 away from the fixing plate 11. When DC power is applied to the transmission line, the lower connector 1 is placed at the bottom of the transmission line, and the upper connector 2 is rotated to move the upper connector 2 to the top of the transmission line. Spring 5's elasticity pushes sliding rod 3 to move, causing support frames 4 to move closer together, thus fixing support frames 4 to the surface of the power transmission line and supporting and fixing the power transmission line. Pushing push rods brings them closer together, causing moving rod 7 to move into mounting frame 9, placing fixing frame 8 on both sides of mounting frame 9. Releasing push plate 10 causes second spring 12 to push mounting plate 13 to move, causing moving rod 7 to move, thus moving one end of moving rod 7 into fixing frame 8 and interlocking with fixing frame 8, fixing upper connector 2 and lower connector 1. This allows for quick disassembly and installation of the short-connector, reducing high-altitude work time and increasing construction safety.
