Description

Technical Field

[0001] The present invention relates to the technical field of overhead transmission lines, and more particularly, to a ground wire ice melting connection device. Background Art

[0002] Under extreme climate conditions, especially for overhead transmission lines in some alpine mountainous areas of our country, the overhead transmission lines are often severely iced in winter. There is less ice on the conductors and more ice on the ground wires, which will cause the line sag to increase. When the line vibrates and dances due to wind, flashovers are more likely to occur between the lines. In severe cases, the line may trip, thus affecting the normal operation of the line. At the same time, the ice thickness difference on both sides of the iron tower is relatively large, and the unbalanced tension on the tower top will increase. When the iron tower is covered with ice, the unbalanced tension will increase. When the iron tower cannot bear this load, the pole may fall or the tower may collapse.

[0003] For the existing ground wire ice melting automatic connection device, generally, a conductive rod is driven by a motor to rotate downward from the cross arm, and the conductive rod drives the moving contact to connect with the wire current combining device to complete ice melting current conduction. In the actual application process, the moving contact is fixedly installed on the conductive rod and rotates synchronously with the conductive rod. However, in the actual application process, there is a deviation in the rotation angle of the conductive rod driven by the motor, and it may not rotate in place, resulting in a relatively high failure rate of closing the moving contact and the static contact.

Detailed embodiments

[0035] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0036] Combined with reference to Figures 1 to 17As shown in the figure, the present invention provides a grounding wire de-icing connection device, which includes: a moving contact 10 having a closing position and a tripping position; a driving assembly 20 configured to be connected to a structure 30 to be installed; a rotating body 40, the driving assembly 20 is drivingly connected to the rotating body 40 to drive the rotating body 40 to rotate; a holding mechanism 50, including a first holding part 51 and a second holding part 52 that are in transmission cooperation, the first holding part 51 is configured to be installed on the structure 30 to be installed, the second holding part 52 is installed on the rotating body 40, the moving contact 10 is connected to the second holding part 52, and the holding mechanism 50 can keep the moving contact 10 in the closing posture all the time during the rotation of the moving contact 10 along with the rotating body 40; the second holding part 52 includes a first mounting seat 521, a connecting seat 522 and a transmission structure 523, the connecting seat 522 is connected to the rotating body 40, the first mounting seat 521 is rotatably arranged on the connecting seat 522, the moving contact 10 is fixedly installed on the first mounting seat 521, the first end of the transmission structure 523 is drivingly connected to the first mounting seat 521, when the rotating body 40 rotates, the rotating body 40 drives the transmission structure 523 to rotate around the rotation axis of the rotating body 40, so that the second end of the transmission structure 523 forms a transmission cooperation with the first holding part 51 to drive the first mounting seat 521 to rotate around its own central axis relative to the connecting seat 522.

[0037] In this embodiment, the structure 30 to be installed can be the tower arm of a transmission tower. The moving contact 10 has a closing position and a tripping position. When the moving contact 10 is in the closing position, the moving contact 10 can be in close contact with the static contact 105 to form an electric current loop to achieve de-icing. When the moving contact 10 is in the tripping position, the moving contact 10 is separated from the static contact 105. The driving assembly 20 is used to drive the rotating body 40 to rotate, so that the rotating body 40 can be rotated to a suitable position. The second holding part 52 is installed on the rotating body 40 and rotates along with the rotating body 40. The moving contact 10 is connected to the second holding part 52, and the second holding part 52 rotates to drive the moving contact 10 to rotate. During the rotation of the rotating body 40, the holding mechanism 50 can keep the moving contact 10 in the closing posture all the time during the rotation of the moving contact 10 along with the rotating body 40. The closing posture refers to the posture in which the moving contact 10 can be in contact with the moving contact 10 to form a closed loop. When the moving contact 10 is in this posture, only by moving the moving contact 10 to the closing position can the closing of the moving contact 10 be completed, and there is no need to adjust the angle of the moving contact 10.

[0038] When the driving component 20 drives the rotating body 40 to rotate, since the transmission structure 523 is connected to the rotating body 40, the transmission structure 523 rotates around the rotation axis of the rotating body 40 along with the rotating body 40. At this time, the second end of the transmission structure 523 forms a transmission cooperation with the first holding portion 51. Through the transmission cooperation, the first end of the transmission structure 523 drives the first mounting seat 521 to rotate, and then the first mounting seat 521 drives the moving contact 10 to rotate, so that the moving contact 10 always remains in the closing posture. Through the above setting, the moving contact 10 can automatically adjust its posture during rotation, and it can ensure that the moving contact 10 is not affected by the rotation of the rotating body 40 during rotation, so that it can always maintain the closing posture. Even if there is a certain deviation in the rotation angle of the rotating body 40, the moving contact 10 can still achieve closing with the static contact 105, thus avoiding the closing failure caused by the change of the rotation angle and improving the efficiency and success rate of the ice melting operation.

[0039] In winter, when the ice on the line is serious, it will cause the line sag to become larger. When the line vibrates and dances due to wind, flashover is likely to occur between the lines. In severe cases, it can cause the line to trip, thus affecting the normal operation of the line. At the same time, the ice thickness difference on both sides of the iron tower is relatively large, and the unbalanced tension on the top of the tower will increase. When the iron tower is covered with ice, the unbalanced tension will increase. When the iron tower cannot bear this load, it will cause the pole to fall or the tower to collapse. The relative conductor can short-circuit two phase conductors into a loop, and the ground wire needs to be short-circuited by power supply personnel temporarily. The traditional ice melting method requires manual climbing of the tower, which has great potential safety hazards. In addition, since the overhead ground wire on the iron tower cannot resist part of the ice by the heat generated by the load current like the transmission conductor, its ice thickness generally far exceeds that of the transmission conductor. Therefore, the operator needs to melt the ice on the ground wire in time. During the actual ice melting process, the operator needs to climb onto the transmission tower and connect the ground wire to the transmission conductor through an insulating operating rod, so that a short circuit occurs between the transmission conductor and the ground wire and generates heat, thereby automatically melting the ice on the transmission conductor and the ground wire. The prior art has the following defects: the staff needs to climb onto the transmission tower for operation, which is highly dangerous, and needs to manually connect the transmission conductor and the ground wire, which is troublesome to operate and has low wiring efficiency. The ground wire ice melting wiring device of the present application does not need to be manually closed, and has a relatively high wiring efficiency. The ground wire ice melting wiring device of the present application is provided with a manual function. After the electric function fails, the device can be switched on and off through the manual function.

[0040] Refer to in combination Figures 1 to 17As shown, in an embodiment of the present invention, the first holding portion 51 includes a first bevel gear 511, the transmission structure 523 includes a second bevel gear 5231, a third bevel gear 5232 and a transmission shaft 5233. The transmission shaft 5233 extends along the first direction. The second bevel gear 5231 and the third bevel gear 5232 are respectively arranged at both ends of the transmission shaft 5233. The second bevel gear 5231 meshes with the first bevel gear 511. A fourth bevel gear 524 is rotatably arranged on the connecting seat 522. The fourth bevel gear 524 meshes with the third bevel gear 5232. The fourth bevel gear 524 is connected to the first mounting seat 521.

[0041] In this embodiment, when the driving assembly 20 drives the rotating body 40 to rotate, since the transmission structure 523 is connected to the rotating body 40, therefore, the transmission structure 523 rotates around the rotation axis of the rotating body 40 along with the rotating body 40. At this time, the second bevel gear 5231 on the transmission structure 523 meshes with the first bevel gear 511, so that the transmission shaft 5233 rotates around its own rotation axis and drives the third bevel gear 5232 to rotate. The third bevel gear 5232 rotates to drive the fourth bevel gear 524 to rotate. Since the fourth bevel gear 524 is connected to the first mounting seat 521, it can drive the first mounting seat 521 to rotate, and then drive the moving contact 10 to rotate, so that the moving contact 10 is always in the closing posture.

[0042] As can be seen from the above, through the above settings, the posture of the moving contact 10 does not change with the rotation of the rotating body, which is realized by the compensation effect of the first bevel gear, the second bevel gear, the third bevel gear and the fourth bevel gear.

[0043] Combined with reference to Figures 1 to 17 As shown, in an embodiment of the present invention, the connecting seat 522 is slidably connected to the rotating body 40. The ground wire deicing connection device further includes a reciprocating linear driving mechanism 60. The reciprocating linear driving mechanism 60 is installed on the rotating body 40. The reciprocating linear driving mechanism 60 is drivingly connected to the connecting seat 522 to drive the connecting seat 522 to perform reciprocating linear motion along the first direction.

[0044] In this embodiment, through the reciprocating linear driving mechanism 60, the position of the connecting seat 522 can be accurately controlled, and then the position of the moving contact 10 on the rotating body 40 can be adjusted, so that the device can be applied to transmission lines with different string lengths. For transmission lines with different string lengths, the height position of the static contact 105 is different. Through the above settings, the moving contact 10 can be closed with the static contact 105 in different situations, enhancing the versatility of the device.

[0045] Combined with reference to Figures 1 to 17As shown, in an embodiment of the present invention, along the second direction, the rotating body 40 has a first side and a second side arranged oppositely. The connecting seat 522 includes a first connecting part 5221 and a second connecting part 5222. The first connecting part 5221 is slidably arranged on the first side, and the second connecting part 5222 is slidably arranged on the second side. The first direction is perpendicular to the second direction. One end of the first mounting seat 521 is rotatably connected to the first connecting part 5221, and the other end of the first mounting seat 521 is rotatably connected to the second connecting part 5222. The reciprocating linear driving mechanism 60 is drivingly connected to any one of the first connecting part 5221 and the second connecting part 5222.

[0046] In this embodiment, the reciprocating linear driving mechanism 60 is drivingly connected to any one of the first connecting part 5221 and the second connecting part 5222, that is, the reciprocating linear driving mechanism 60 can be drivingly connected to the first connecting part 5221 or can be drivingly connected to the second connecting part 5222.

[0047] The reciprocating linear driving mechanism 60 is drivingly connected to any one of the first connecting part 5221 and the second connecting part 5222, so that the first connecting part 5221 or the second connecting part 5222 drivingly connected to the reciprocating linear driving mechanism 60 moves along the first direction. Since the first connecting part 5221 and the second connecting part 5222 are connected together by the first mounting seat 521, when one of them moves along the first direction, it can synchronously drive the other to move along the first direction, thereby realizing the position adjustment of the moving contact 10 relative to the rotating body 40.

[0048] It should be noted that through the setting of the reciprocating linear driving mechanism 60, the position of the moving contact can be accurately controlled. The movement of the moving contact can be synchronized with the rotation of the moving contact or can be carried out separately.

[0049] Combined with reference to Figures 1 to 17 As shown, in an embodiment of the present invention, the ground wire deicing connection device further includes a locking mechanism 70. The locking mechanism 70 is configured to be installed on the structure to be installed 30, and the locking mechanism 70 can lock the moving contact 10 in the open position.

[0050] In this embodiment, the locking mechanism 70 can lock the moving contact 10 in the open position, which means that during the non-operating state or maintenance, the moving contact 10 will not accidentally move to the closed position due to external factors (such as wind force and gravity), significantly improving the safety of the operator and avoiding unnecessary power accidents and risks of equipment damage. In bad weather or non-use conditions, the locking mechanism 70 can prevent the accidental movement of the moving contact 10. The setting of the locking mechanism 70 simplifies the operation process. After the ice melting operation is completed, the operator can fix the moving contact 10 in the open position through the locking mechanism 70, without the need for continuous monitoring or manual maintenance of the open state, reducing the operation difficulty and improving the work efficiency.

[0051] Referring to Figures 1 to 17 As shown, in an embodiment of the present invention, the locking mechanism 70 includes a mounting bracket 71 and a telescopic structure 72. The mounting bracket 71 is configured to be connected to the structure 30 to be installed. The telescopic structure 72 is installed on the mounting bracket 71. The telescopic structure 72 includes a moving part 721. The moving part 721 is arranged to be movable relative to the mounting bracket 71 in the horizontal direction. A mating part 41 is provided on the rotating body 40. The moving part 721 can form a limiting fit with the mating part 41 to lock the moving contact 10 in the open position.

[0052] In this embodiment, when the rotating body 40 rotates to the horizontal position, the moving part 721 moves in the horizontal direction and can form a limiting fit with the mating part 41 in the vertical direction to lock the rotating body 40 in the horizontal position, and further lock the moving contact 10 in the open position. The moving part 721 can bear the weight of the rotating body 40 and cooperate with the driving assembly to pull the rotating body 40 to prevent the rotating body 40 from falling.

[0053] Referring to Figures 1 to 17 As shown, in an embodiment of the present invention, the telescopic structure 72 further includes a driving part 722. The driving part 722 is drivingly connected to the moving part 721. A strip-shaped hole is provided on the mating part 41. The strip-shaped hole extends in the vertical direction. A wedge-shaped structure 723 is provided at one end of the moving part 721 away from the driving part 722. The inclined surface of the wedge-shaped structure 723 faces the structure 30 to be installed. The wedge-shaped structure 723 is slidably arranged in the strip-shaped hole and forms a limiting fit with the top surface of the strip-shaped hole.

[0054] In this embodiment, the locking mechanism 70 is located on one side of the driving assembly 20. Meanwhile, the locking mechanism 70 is located on the rotation path of the rotating body 40. The driving part 722 is drivingly connected to the moving part 721 to drive the moving part 721 to move horizontally in a direction approaching or departing from the driving assembly 20. When it is necessary to lock the moving contact 10 in the opening position, the driving part 722 drives the moving part 721 to move horizontally in a direction departing from the driving assembly 20, so that the wedge-shaped structure 723 penetrates into the strip-shaped hole. At this time, the inclined surface of the wedge-shaped structure 723 provided on the moving part 721 is in close contact with the top surface of the strip-shaped hole to limit the mating part 41 in the vertical direction, thereby locking the moving contact 10 in the opening position and preventing the rotating body 40 from falling. When unlocking, the driving part 722 drives the moving part 721 to move horizontally in a direction approaching the driving assembly 20, so that the wedge-shaped structure 723 disengages from the strip-shaped hole. The height of the inclined surface of the wedge-shaped structure 723 gradually decreases in a direction departing from the driving assembly 20. By controlling the length of the wedge-shaped structure 723 extending into the strip-shaped hole by the driving part 722, the locking degree can be adjusted.

[0055] When the ground wire needs to be de-iced, the ground wire de-icing connection device is started. The device is closed, and the conducting wire is connected to form a loop. The specific working mode is as follows: After starting the ground wire de-icing connection device, after the device receives the closing signal, the locking mechanism is opened, and the moving part 721 of the locking mechanism starts to retract. When reaching the limit position, the wedge-shaped structure 723 disengages from the strip-shaped hole, the driving assembly 20 is started, and the rotating body 40 starts to rotate. At the same time, the moving contact moves to the corresponding position. When the rotating body 40 rotates to the vertical position (i.e., Figure 2 the position in), the moving contact and the static contact are closed. After the closing is completed, the device stops moving, and the conducting wire is connected to start de-icing. After the ground wire de-icing is completed, the rotating body 40 rotates toward the side where the structure to be installed is located. During the rotation, the moving contact can move to the corresponding position. When the rotating body 40 reaches the horizontal position ( Figure 3 the position in), the locking mechanism is started to lock the rotating body in the current position, and the device completes the work.

[0056] In one embodiment, the mating part 41 is a plate structure, and the telescopic structure 72 is an electric push rod.

[0057] Refer to in combination Figures 1 to 17As shown, in an embodiment of the present invention, the ground wire ice melting connection device further includes an angle measuring mechanism 80. The angle measuring mechanism 80 includes a second mounting seat 81, a third mounting seat 82, a first rotating shaft 83, a second rotating shaft 84, a first gear 85, a second gear 86 and a rotary encoder. The second mounting seat 81 and the third mounting seat 82 are both configured to be fixedly installed on the structure 30 to be installed. The first rotating shaft 83 passes through the second mounting seat 81 and rotates relative to the second mounting seat 81. The second rotating shaft 84 passes through the third mounting seat 82 and rotates relative to the third mounting seat 82. The first gear 85 is fixedly sleeved on the first rotating shaft 83. The second gear 86 is fixedly sleeved on the second rotating shaft 84. One end of the first rotating shaft 83 is fixedly connected to the rotating body 40. The first gear 85 meshes with the second gear 86. The rotary encoder is installed on the second rotating shaft 84.

[0058] In this embodiment, when the rotating body 40 rotates under the drive of the drive assembly 20, it drives the first rotating shaft 83 to rotate. The rotation of the first rotating shaft 83 drives the first gear 85 to rotate. The rotation of the first gear 85 drives the second gear 86 to rotate. The rotation of the second gear 86 drives the second rotating shaft 84 to rotate. The rotary encoder is installed on the second rotating shaft 84, and the rotation angle of the rotating body 40 is measured by detecting the rotation position of the second rotating shaft 84.

[0059] In an embodiment of the present invention, the third mounting seat 82 is a bearing seat, and a first bearing 821 is installed on the bearing seat. The second rotating shaft 84 passes through the first bearing 821.

[0060] Combined with reference to Figures 1 to 17 As shown, in an embodiment of the present invention, the drive assembly 20 includes a first connecting portion 21, a first drive motor 22, a first insulator 23 and a second insulator 24. The first connecting portion 21 is arranged at an angle with the output shaft 25 of the first drive motor 22. One end of the first connecting portion 21 is configured to be connected to the structure 30 to be installed. The output shaft 25 of the first drive motor 22 is rotatably connected to the second end of the first connecting portion 21. A second connecting portion 26 is arranged on the output shaft 25, and the second connecting portion 26 is connected to the rotating body 40. The first insulator 23 is sleeved on the output shaft 25, and the second insulator 24 is sleeved on the first connecting portion 21.

[0061] In this embodiment, the first insulator 23 can separate the first drive motor 22 from the rotating body 40, and the second insulator 24 can separate the structure 30 to be installed from the rotating body 40, ensuring that the structure 30 to be installed and the first drive motor 22 are in a non-energized state when the device is melting ice. When the device needs to melt ice, the output shaft 25 of the first drive motor 22 rotates to drive the first insulator 23 installed thereon to rotate, further driving the rotating body 40 to rotate. When the ice melting of the device is completed, the output shaft 25 of the first drive motor 22 drives the first insulator 23 to rotate in the reverse direction.

[0062] In one embodiment, the first drive motor 22 is a reduction motor. The drive assembly of the present application adopts a double-insulator scheme, which effectively reduces the volume and mass of the device while achieving high-efficiency rotation of the device. By using a high-reduction-ratio reduction motor with a reduction ratio of up to 6000:1, compared with the prior-art rotating device that requires two-stage speed reducers for speed reduction, the weight and volume are further reduced. Through the miniaturization of the drive assembly, the installation difficulty of the product is reduced.

[0063] In one embodiment, the second connecting portion 26 is a flange.

[0064] In one embodiment, the ground wire ice melting wiring device further includes two proximity switches and a control system. The two proximity switches respectively correspond to the closing position and the opening position of the moving contact 10. The two proximity switches and the first drive motor 22 are all communicatively connected to the control system. The drive assembly further includes a connecting plate, the connecting plate is connected to the structure 30 to be installed, the first drive motor 22 is installed on the connecting plate, the output shaft 25 of the first drive motor 22 passes through the connecting plate, and the two proximity switches are installed on the connecting plate. The output shaft 25 of the first drive motor 22 has a first rotation position and a second rotation position. When the output shaft 25 rotates to the first rotation position, the moving contact is in the closing position. When the output shaft 25 rotates to the second rotation position, the moving contact is in the opening position. When the output shaft 25 rotates to the first rotation position, one of the two proximity switches senses and sends a control signal to stop the driving of the first drive motor 22. When the output shaft rotates to the second rotation position, the other proximity switch of the two proximity switches senses and sends a control signal to stop the driving of the first drive motor 22. Through the above settings, the operating state of the entire wiring device can be accurately sensed.

[0065] Referring to Figures 1 to 17 As shown in the figure, in one embodiment of the present invention, the first holding portion 51 further includes a fourth mounting seat 512 and a third rotating shaft 513.

The other end of the lead screw 62 passes through the second connection sub-body 5222 and is arranged in the third bearing 5252 on the corresponding side. Both nuts are sleeved on the lead screw 62. The two nuts are arranged at intervals in the first direction and are both fixedly connected to the second connection sub-body 5222. The side of the second connection sub-body 5222 away from the first connection sub-body 5221 is slidably arranged on the guide rail 42 on the second side of the rotating body 40. The lead screw 62 rotates under the drive of the second drive motor 61, so that the nut drives the second connection sub-body 5222 to perform a reciprocating linear motion in the first direction.

[0067] Referring to Figures 1 to 17 As shown, in an embodiment of the present invention, guide rails 42 are provided on both the first side and the second side of the rotating body 40. The first connection sub-body 5221 is slidably arranged on the guide rail 42 on the first side of the rotating body 40, and the second connection sub-body 5222 is slidably arranged on the guide rail 42 on the second side of the rotating body 40.

One end of the transmission shaft 5233 is arranged in the third bearing 5252 on the corresponding side, and the other end of the transmission shaft 5233 is arranged in the third bearing 5252 on the corresponding side.

[0068] Specifically, the first connection sub-body 5221 includes a connected slider 526 and a U-shaped connection frame 527.

Along the first direction, through holes are provided on both opposite sides of the U-shaped connection frame 527, and the transmission shaft 5233 can pass through the two through holes. A bearing seat is provided on the U-shaped connection frame 527, and a fourth bearing is installed on the bearing seat. One end of the fourth bevel gear 524 passes through the fourth bearing and is fixedly connected to the first mounting seat 521.

[0069] Referring to Figures 1 to 17As shown in the figure, in one embodiment of the present invention, the ground wire de-icing connection device further includes a closing mechanism 100. The closing mechanism 100 includes a guide plate 106, a connecting plate 102 and a splitting plate 103 which are connected to each other. Six wire clamps 101 are connected to the outer periphery of the connecting plate 102. A conductive plate 104 is connected to the side of the splitting plate 103 away from the connecting plate 102. A static contact 105 is provided on the conductive plate 104. One end of the guide plate 106 is connected to the conductive plate 104. The static contact 105 is located in the inner cavity of the guide plate 106, and the end of the guide plate 106 away from the conductive plate 104 is conical, which can guide when the moving contact 10 is closed with the static contact 105, and can effectively improve the accuracy of closing. Among them, the splitting plate 103 and the wire clamps 101 can be customized according to the number of line splits and the split spacing. The guide plate 106 adopts a conical structure, which can guide the moving contact into the static contact when the contact is offset, realizing the precise closing of the moving contact and the static contact.

[0070] It should be noted that the ground wire de-icing connection device of the present application is applicable to various split conductor lines, with strong applicability and high versatility. That is, the ground wire de-icing connection device of the present application is not limited to six-split conductors, and three-split, four-split, and eight-split conductors are also applicable.

[0071] In one embodiment, the part where the moving contact 10 and the static contact 105 are closed adopts a conical structure, which can play a guiding role by itself. At the same time, if the static contact freezes, the conical structure can pierce the ice layer to ensure the smooth closing and opening of the moving contact and the static contact.

[0072] Combined with reference to Figures 1 to 17 As shown in the figure, in one embodiment of the present invention, the locking mechanism 70 further includes a sensor 73. The sensor 73 is communicatively connected to the first driving motor 22. When the rotating body 40 rotates to the horizontal position, the sensor 73 sends a control signal. After receiving the control signal, the first driving motor 22 stops driving the rotating body 40 to continue rotating.

[0073] Combined with reference to Figures 1 to 17 As shown in the figure, in one embodiment of the present invention, the ground wire de-icing connection device further includes a third insulator 90. A grading ring 91 is provided at both ends of the third insulator 90. One of the grading rings 91 is connected to the structure to be installed 30, and the other grading ring 91 is connected to the closing mechanism 100.

[0074] It should be noted that the grading ring 91 adopts the existing technology, and the specific structure will not be described here.

[0075] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: A driving component, a moving contact, a rotating body, and a holding mechanism are provided. The driving component is used to drive the rotating body to rotate. The second holding portion is installed on the rotating body and rotates with the rotating body. The moving contact is connected to the second holding portion, and the second holding portion rotates to drive the moving contact to rotate. During the rotation of the rotating body, the holding mechanism can keep the moving contact in the closing posture all the time during the rotation with the rotating body. When the driving component drives the rotating body to rotate, since the transmission structure is connected to the rotating body, the transmission structure rotates around the rotation axis of the rotating body with the rotating body. At this time, the second end of the transmission structure forms a transmission cooperation with the first holding portion. Through the transmission cooperation, the first end of the transmission structure drives the first mounting seat to rotate, and then the first mounting seat drives the moving contact to rotate, so that the moving contact is always in the closing posture. Through the above settings, the moving contact can automatically adjust its posture during rotation, which can ensure that the moving contact is not affected by the rotation of the rotating body during rotation and can always be kept in the closing posture. Even if there is a certain deviation in the rotation angle of the rotating body, the moving contact can still achieve closing with the static contact, thus avoiding the closing failure caused by the change of the rotation angle and improving the efficiency and success rate of the ice melting operation.
