These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0029] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0030] In the related art, the arcing device includes two arcing horns, which are fixed at both ends of the insulator string. There is a certain discharge gap between the two arcing horns. During operation, when an overvoltage occurs on the line (for example, due to a lightning strike or improper operation), the discharge gap will first break down, thereby directing the overvoltage to the ground, preventing the overvoltage from directly acting on the insulator string and protecting the insulator from breakdown or damage. Different sizes of discharge gaps are often required for different usage scenarios. To this end, the arcing horns are usually disassembled, then adjusted to the appropriate position and re-fixed, making the adjustment process of the discharge gap more cumbersome.

[0031] It can be seen that it is difficult for the arc striking device to adjust the size of the discharge gap according to different actual installation requirements.

[0032] To this end, an embodiment of the present application provides an arcing device, comprising: an arcing member, wherein at least two arcing members are movably disposed at each end of an insulator string, each having a discharge end, and a discharge gap is formed between the discharge end at one end of the insulator string and the discharge end at the other end of the insulator string; and an adjustment assembly, wherein the adjustment assembly includes a power member and a connector, wherein the power member is connected to at least one arcing member via the connector, and the power member controls the movement of at least one arcing member relative to the insulator string to adjust the size of the discharge gap. Thus, during use, the power member only needs to control the movement of the arcing member to adjust the position of the discharge end on the arcing member, thereby more conveniently adjusting the size of the discharge gap. This solves the problem in the prior art that arcing devices are difficult to adjust the size of the discharge gap according to different actual installation requirements.

[0033] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0034] like Figure 1 As shown, an arcing device provided in an embodiment of the present application includes: an arcing member 100, wherein at least two arcing members 100 are movably disposed at both ends of an insulator string 10, and each arcing member 100 has a discharge end 110, and a discharge gap 200 is formed between the discharge end 110 at one end of the insulator string 10 and the discharge end 110 at the other end of the insulator string 10;

[0035] The adjustment component 300 includes a power member 310 and a connecting member 320. The power member 310 is connected to at least one arcing member 100 through the connecting member 320. The power member 310 controls the movement of at least one arcing member 100 relative to the insulator string 10 to adjust the size of the discharge gap 200.

[0036] It should be noted that when the arcing member 100 moves relative to the insulator string 10, the position of the discharge end 110 will change, thereby adjusting the relative position between the discharge end 110 at one end of the insulator string 10 and the discharge end 110 at the other end of the insulator string 10, that is, adjusting the size of the discharge gap 200.

[0037] When in use, it is only necessary to control the movement of the arcing member 100 through the power member 310 to adjust the position of the discharge end 110 on the arcing member 100, thereby more conveniently adjusting the size of the discharge gap 200, solving the problem in the prior art that the arcing device is difficult to adjust the size of the discharge gap 200 according to actual different installation requirements.

[0038] In the embodiment of the present application, two arcing members 100 are provided, one at each end of the insulator string 10. This optimizes the number of arcing members 100 and reduces cost. Of course, other numbers of arcing members 100 can be used according to actual needs, and this is not a limitation.

[0039] like Figure 1 As shown, in some embodiments, the connecting member 320 is simultaneously connected to the arcing members 100 located at both ends of the insulator string 10, so that the power member 310 controls the arcing members 100 located at both ends of the insulator string 10 to move synchronously.

[0040] In the embodiment of the present application, since there are two arcing members 100, it is sufficient to connect the connecting member 320 to both arcing members 100. This allows the power member 310 to synchronously control the two arcing members 100 through the connecting member 320, thereby increasing the adjustment efficiency of the discharge gap 200 and expanding the adjustment range.

[0041] like Figure 1 As shown, in some embodiments, the arcing member 100 includes a rotating rod 120, which is rotatably set on the end of the insulator string 10, and the discharge end 110 is located on the rotating rod 120; the connecting member 320 is transmission-connected to each rotating rod 120, so that the power member 310 controls each rotating rod 120 to rotate synchronously.

[0042] It should be noted that the extension direction of the rotating rod 120 is perpendicular to the extension direction of the insulator string 10 , and the rotating rod 120 is rotatably connected to the insulator string 10 so that the position of the discharge end 110 can be adjusted by rotating the rotating rod 120 .

[0043] At this time, the connecting member 320 is simultaneously in transmission connection with the two rotating rods 120 , so that the power member 310 controls the rotation of the two rotating rods 120 at the same time.

[0044] When in use, the power member 310 is operated, and then the two rotating rods 120 are driven to rotate at the same time under the transmission action of the connecting member 320, thereby simultaneously controlling the positions of the two discharge ends 110 to achieve the purpose of quickly adjusting the discharge gap 200.

[0045] like Figure 1 As shown, in some embodiments, the arcing member 100 further includes a connecting rod 130 , which is used to be connected to the end of the insulator string 10 , and the rotating rod 120 is rotatably disposed on the connecting rod 130 .

[0046] The connecting rod 130 is coaxially arranged with the rotating rod 120, and one end of the rotating rod 120 is rotatably connected to the connecting rod 130. The connecting rod 130 can be connected to the end of the insulator string 10 by screw connection, pin connection, clamping or other methods, which are not limited.

[0047] During on-site installation, it is only necessary to fix the connecting rod 130 to the end of the insulator string 10 to achieve the purpose of installing the entire arcing member 100, thereby improving the convenience of on-site installation operations.

[0048] like Figure 1 As shown, specifically, the rotating rod 120 is coaxially provided with a connecting shaft 121 , and the rotating rod 120 is rotatably connected to the connecting rod 130 via the connecting shaft 121 .

[0049] It should be noted that the connecting shaft 121 is coaxially disposed at the end of the rotating rod 120 facing the connecting rod 130. The connecting shaft 121 is coaxially plugged into and rotatably connected to the end of the connecting rod 130 facing away from the insulator string 10. The connecting shaft 121 can be secured to the end of the rotating rod 120 by welding, integral molding, screwing, or other means, without limitation. This allows the rotating rod 120 to rotate relative to the connecting rod 130.

[0050] In practice, in order to reduce the possibility of the connecting shaft 121 being detached from the connecting rod 130, for example, a stopper can be provided at the end of the connecting shaft 121 away from the rotating rod 120. The stopper has a diameter larger than that of the connecting shaft 121 and is embedded in the interior of the connecting rod 130. In this way, the stopper limits the connecting shaft 121, reducing the possibility of the connecting shaft 121 being detached from the connecting rod 130.

[0051] In other embodiments, the connecting shaft 121 and the connecting rod 130 may be fixed. In this case, the connecting shaft 121 rotates relative to the rotating rod 120. The rotating rod 120 may also be rotatably connected to the connecting rod 130 in other ways, which is not limited thereto.

[0052] like Figure 1 As shown, in some embodiments, the connecting member 320 includes a transmission rod 321 , one end of the transmission rod 321 is transmission-connected to one of the rotating rods 120 , and the other end of the transmission rod 321 is transmission-connected to the other rotating rod 120 .

[0053] It should be noted that the transmission rod 321 is located between the two rotating rods 120, and the two ends of the transmission rod 321 are respectively facing the two rotating rods 120, and the ends of the transmission rod 321 are transmission-connected with the rotating rods 120. Therefore, the rotation of the two rotating rods 120 is synchronized through the transmission rod 321.

[0054] During implementation, a bracket can also be set on one side of the transmission rod 321, so that the transmission rod 321 can be installed on the bracket, and then the transmission rod 321 is supported by the bracket to ensure the stability of the transmission rod 321 when in use; of course, the bracket can also be fixed to the connecting rod 130 or other components, and there is no restriction on this.

[0055] like Figure 1As shown, further, the connecting member 320 also includes a first gear 322 coaxially arranged on the rotating rod 120 and a second gear 323 coaxially arranged at the end of the transmission rod 321, and a second gear 323 is provided at both ends of the transmission rod 321. The first gears 322 on the two rotating rods 120 are respectively engaged with the two second gears 323; the power member 310 is connected to any one of the first gear 322, the second gear 323, the transmission rod 321 and the rotating rod 120.

[0056] In this embodiment, the first gear 322 can be coaxially fixed to the end of the rotating rod 120 facing the connecting rod 130 by welding, sleeve connection, threading, or other means, and the connecting shaft 121 is coaxially fixed to the side of the first gear 322 facing the connecting rod 130. The second gears 323 at both ends of the transmission rod 321 respectively mesh with the first gears 322 on the two rotating rods 120, thereby synchronizing the rotation of the two rotating rods 120 through gear transmission.

[0057] It should be noted that the power member 310 can be a motor, preferably a servo motor, and the motor model is not limited. In implementation, the output shaft of the power member 310 can be directly or indirectly connected to the first gear 322, and can also be connected to the second gear 323, the transmission rod 321, the rotating rod 120, or the connecting shaft 121. It only needs to be able to drive any of the rotating rods 120 to rotate, and there is no limitation on this.

[0058] If the output shaft of the power member 310 is to be directly connected to the first gear 322, for example, the output shaft of the power member 310 can be coaxially fixed to the first gear 322, so that while driving the rotating rod 120 to rotate, the other rotating rod 120 can also be driven to rotate through the transmission rod 321. If the output shaft of the power member 310 is to be indirectly connected to the first gear 322, a sprocket and a chain for transmission can be provided on the output shaft of the power member 310, and the first gear 322 can also be coaxially provided with a sprocket, and the chain can be wound around both sprockets at the same time, thereby indirectly connecting the power member 310 and the first gear 322 via a chain drive, and the purpose of controlling the rotation of the rotating rod 120 can also be achieved.

[0059] During use, the power member 310 is turned on to control one of the rotating rods 120 to rotate, and then the other rotating rod 120 is driven to rotate by the first gear 322, the second gear 323 and the transmission rod 321, so as to adjust the relative position between the two discharge ends 110, that is, to adjust the size of the discharge gap 200.

[0060] In other embodiments, for the transmission method between the transmission rod 321 and the rotating rod 120, a worm gear can be provided on the rotating rod 120, and a worm engaged with the worm gear can be provided on the transmission rod 321, so as to realize the transmission between the transmission rod 321 and the rotating rod 120. Of course, other transmission methods can also be used, and there is no limitation to this.

[0061] In addition, in other embodiments, the arcing member 100 may be slidably disposed at the end of the insulator string 10 to adjust the size of the discharge gap 200 by sliding the arcing member 100. In this case, the power member 310 may also be a cylinder, a hydraulic cylinder, an electric telescopic rod, etc.

[0062] like Figure 1 As shown, in some embodiments, the arcing member 100 further includes an arcing rod 140 , which is connected to the rotating rod 120 . The arcing rod 140 and the rotating rod 120 are arranged at an angle, and the end of the arcing rod 140 away from the rotating rod 120 is the discharge end 110 .

[0063] It should be noted that the arcing rod 140 is connected to the end of the rotating rod 120 away from the connecting rod 130. The arcing rod 140 can be connected to the rotating rod 120 by welding, integral molding, or other methods. The arcing rod 140 is arranged at an angle to the rotating rod 120. Preferably, the arcing rod 140 and the rotating rod 120 are perpendicular to each other. The end of the arcing rod 140 away from the rotating rod 120 is the discharge end 110.

[0064] When the rotating rod 120 rotates, it drives the arcing rod 140 to swing. At the same time, under the action of the connecting member 320, the two arcing rods 140 swing synchronously, so that the two discharge ends 110 move closer to or farther away from each other, thereby achieving the purpose of adjusting the discharge gap 200.

[0065] During implementation, the discharge end 110 may be spherical in structure, thereby reducing the sharpness of the discharge end 110 and reducing the possibility of injury to personnel during production, transportation or storage; and also improving the aesthetics.

[0066] In summary, the arc-striking device provided in the embodiment of the present application, when in use, only needs to control the movement of the arc-striking member 100 through the power member 310, so as to adjust the position of the discharge end 110 on the arc-striking member 100, thereby more conveniently adjusting the size of the discharge gap 200, and solving the problem in the prior art that the arc-striking device is difficult to adjust the size of the discharge gap 200 according to different actual installation requirements.

[0067] Finally, it should be noted that those skilled in the art will readily conceive of other embodiments of the present invention after considering the specification and practicing the invention disclosed herein. This invention is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein.
