Typically, they use manually rotating rollers or stepper motors or DC motors and transmission mechanisms to control the distance between the two electrodes to produce arcs. However, they cannot study the electric arcs generated when the electrodes are at different angles. Utility Model Content

[0048] In fields such as power systems, aerospace, and military equipment, the arc performance of high-voltage electrical equipment directly affects the reliability and safety of the equipment. Therefore, in-depth research on arcs is necessary. This research includes the generation of an arc, also known as arc drawing.

[0049] In related technologies, arc-generating devices typically generate arcs by changing the distance between two electrodes. This means they can only study arcs generated at different distances, usually achieved by manually rotating rollers or using stepper motors or DC motors and transmission mechanisms to control the distance between the electrodes. However, they cannot study arcs generated when the electrodes are at different angles. Therefore, this application provides a high-voltage arc-generating device to solve or improve the problem of not being able to study arcs generated when the electrodes are at different angles.

[0050] The following is combined with Figures 1 to 7 This describes an embodiment of the present application.

[0051] According to an embodiment of this application, a high-voltage arc-drawing device is provided, comprising: a frame 1, a connecting seat 2, at least two electrode assemblies 3, at least two connecting rods 4, and a drive mechanism 5.

[0052] Specifically, such as Figure 1 , Figure 6 and Figure 7As shown, the connecting seat 2 is connected to the frame 1, and the connecting seat 2 is provided with at least two first hinge parts 201; each electrode assembly 3 is provided with a second hinge part 304 and a third hinge part 305, and each second hinge part 304 is hinged to each first hinge part 201; the first end of each connecting rod 4 is hinged to each third hinge part 305; the drive mechanism 5 is connected to the frame 1, and the drive mechanism 5 is provided with at least two drive ends 504, each drive end 504 is hinged to the second end of each connecting rod 4, and each drive end 504 can move up and down to adjust the angle between each electrode assembly 3.

[0053] In this embodiment, such as Figure 1 , Figure 6 and Figure 7 As shown, the connecting seat 2 is connected to the frame 1. The connecting seat 2 is provided with at least two first hinge parts 201. The electrode assembly 3 is provided with a second hinge part 304 and a third hinge part 305. Each first hinge part 201 is hinged to a second hinge part 304 of the electrode assembly 3. The electrode assembly 3 rotates about the first hinge part 201 as an axis, and the angle of the electrode assembly 3 connected to the first hinge part 201 can be adjusted.

[0054] The drive end 504 of the drive mechanism 5 is hinged to the first end of the connecting rod 4, and the second end of the connecting rod 4 is hinged to the third hinge part 305. The drive end 504 of the drive mechanism 5 moves up and down along the first direction X, and can move away from or closer to the connecting seat 2. During the process of moving away from or closer to the connecting seat 2, the drive end 504 drives the connecting rod 4 to rotate. The connecting rod 4 drives the electrode assembly 3 to rotate around the first hinge part 201, and adjusts the angle of the electrode assembly 3 connected to the first hinge part 201.

[0055] A high voltage is connected to the electrode assembly 3, which allows an electric arc to be formed when the two electrode assemblies 3 are at different angles, and the electric arc can be studied.

[0056] Wherein, the first direction X is the direction in which the drive end 504 moves toward or away from the connecting seat 2.

[0057] In some embodiments, such as Figure 1 As shown, the frame 1 includes a frame 101 and a fixing plate 102. The fixing plate 102 is fixed on the frame 101, the connecting seat 2 is connected to the bottom of the fixing plate 102, and the drive mechanism 5 is connected to the fixing plate 102.

[0058] In some embodiments, such as Figure 7As shown, the connecting seat 2 is provided with four first hinge parts 201, which are arranged circumferentially around the connecting seat 2 and at equal angular intervals. Four electrode assemblies 3 are provided, and the second hinge parts 304 of the four electrode assemblies 3 are respectively hinged to the four first hinge parts 201. The driving mechanism 5 is provided with four driving ends 504 and four connecting rods 4. The first ends of the four connecting rods 4 are respectively hinged to the third hinge parts 305 of the four electrode assemblies 3, and the second ends of the four connecting rods 4 are respectively hinged to the four driving ends 504. The driving ends 504 move up and down along the first direction X, moving away from or towards the connecting seat 2. During the process of moving away from or towards the connecting seat 2, the driving ends 504 drive the four connecting rods 4 to rotate synchronously. The connecting rods 4 drive the electrode assemblies 3 to rotate synchronously around the first hinge parts 201, thereby adjusting the angle of the four electrode assemblies 3 connected to the four first hinge parts 201.

[0059] In one embodiment, such as Figure 4 and Figure 6 As shown, the electrode assembly 3 includes a connecting rod 301, an insulating block 302, and an electrode 303. Specifically, the two ends of the connecting rod 301 are a second hinge portion 304 and a third hinge portion 305, respectively. The insulating block 302 is fixedly connected to the connecting rod 301. The insulating block 302 is provided with a mounting hole and a notch 3021. The notch 3021 communicates with the mounting hole and is locked by fasteners. The electrode 303 passes through and is installed on the mounting hole.

[0060] In this embodiment, such as Figure 4 As shown, the two ends of the connecting rod 301 are respectively hinged to the first hinge part 201 and the first end of the connecting rod 4. The driving end 504 moves up and down along the first direction X, and can move away from or towards the connecting seat 2. During the process of moving away from or towards the connecting seat 2, the driving end 504 drives the connecting rod 4 to rotate. The connecting rod 4 drives the connecting rod 301 to rotate around the first hinge part 201. The electrode 303 is fixed on the connecting rod 301 by the insulating block 302, which in turn drives the electrode 303 to rotate, and the angle of the electrode 303 is adjusted.

[0061] like Figure 6 As shown, the insulating block 302 is provided with a notch 3021. The size of the notch 3021 can be adjusted by fasteners. After the electrode 303 passes through the mounting hole, the fasteners are used to tighten the insulating block 302, reducing the notch 3021 and securing the electrode to the mounting hole. The position of the electrode 303 on the insulating block 302 can be adjusted.

[0062] The insulating block 302 is used to insulate the electrode 303 from the connecting rod 301, thereby improving safety.

[0063] In some embodiments, such as Figure 4 and Figure 6 As shown, the insulating block 302 is provided with a through hole 11, which is connected to the notch 3021. A threaded hole is provided on the side corresponding to the through hole 11. The fastener is a bolt, which passes through the through hole 11 and the notch 3021 and is threadedly connected to the threaded hole. The size of the notch 3021 is adjusted to clamp or release the electrode 303.

[0064] In one embodiment, such as Figure 4 As shown, the electrode component 303 includes a conductive connecting sleeve 3031 and an electrode rod 3032. Specifically, the conductive connecting sleeve 3031 passes through and is installed on the mounting hole, and the conductive connecting sleeve 3031 is provided with a first thread; the electrode rod 3032 is provided with a second thread adapted to the first thread, and the electrode rod 3032 is threadedly connected to the conductive connecting sleeve 3031 to adjust the depth of the electrode rod 3032 inserted into the conductive connecting sleeve 3031 along its axial direction.

[0065] In this embodiment, such as Figure 6 As shown, by adjusting the size of the fastener adjustment notch 3021, the conductive connecting sleeve 3031 can be fixed at any position on the insulating block 302 along the axial direction of the mounting hole, thereby adjusting the distance between the electrode rods 3032. However, manual adjustment is not very precise. Therefore, by threading the electrode rods 3032 to the conductive connecting sleeve 3031, the position of the electrode rods 3032 can be finely adjusted along the axial direction of the mounting hole, improving the adjustment precision of the distance between the electrode rods 3032. By adjusting the distance and angle between the electrode rods 3032, and changing these two parameters, the electric arc can be studied.

[0066] In some embodiments, the conductive connecting sleeve 3031 is made of copper, and the electrode rod 3032 is made of graphite.

[0067] In one embodiment, such as Figure 6 and Figure 7 As shown, the drive mechanism 5 includes a connecting block 501, a screw 502, and a drive unit. Specifically, the connecting block 501 is provided with at least two drive ends 504. The connecting block 501 has a connecting hole along the lifting direction of the drive ends 504, and the inner wall of the connecting hole is provided with a thread. One end of the screw 502 is rotatably connected to the frame 1, and the other end is rotatably connected to the connecting seat 2. The screw 502 is threadedly connected to the connecting hole. The drive unit is connected to the screw 502 through a transmission assembly 503.

[0068] In this embodiment, such as Figure 6 and Figure 7As shown, the drive unit drives the screw 502 to rotate through the transmission assembly 503. The rotation of the screw 502 causes the connecting block 501 to move along the screw 502. When the connecting block 501 moves downward along the screw 502, the connecting rod 4 rotates and moves downward. The first end of the connecting rod 4 is hinged to the third hinge part 305 of the connecting rod 301, driving the connecting rod 301 to rotate about the second hinge part 304 as the axis in a direction away from the screw 502, adjusting the angle between the electrode rod 3032 connected to the connecting rod 301 and the screw 502. At the same time, the angle between two adjacent electrode rods 3032 or two opposing electrode rods 3032 is adjusted.

[0069] In some embodiments, such as Figure 6 and Figure 7 As shown, the four connecting rods 4, the four connecting rods 301, and the connecting seat 2 can restrict the connecting block 501 and prevent the connecting block 501 from rotating with the screw 502.

[0070] In some embodiments, such as Figure 1 As shown, the first direction X is parallel to the axial direction of the screw 502.

[0071] In some embodiments, such as Figure 6 As shown, the screw 502 is rotatably connected to the connecting seat 2 via the first bearing 13.

[0072] In some embodiments, the drive unit may be a motor.

[0073] In one embodiment, such as Figure 1 and Figure 2 As shown, the transmission assembly 503 includes: a transmission shaft 5031, a first transmission wheel 5032, and a second transmission wheel 5033. Specifically, the transmission shaft 5031 is rotatably connected to the frame 1 and is connected to the drive unit. The first transmission wheel 5032 is installed at the end of the transmission shaft 5031 away from the drive unit. The second transmission wheel 5033 is installed at the end of the screw 502 away from the connecting seat 2, and the first transmission wheel 5032 and the second transmission wheel 5033 are connected to each other.

[0074] In this embodiment, the drive unit drives the transmission shaft 5031 to rotate. The transmission shaft 5031 is connected to the first transmission wheel 5032 and the second transmission wheel 5033, which in turn drives the screw 502 to rotate.

[0075] In some embodiments, such as Figure 1 and Figure 2As shown, both the first transmission wheel 5032 and the second transmission wheel 5033 are bevel gears, which can change the transmission direction. Adjusting the length of the transmission shaft 5031 allows the operator to be positioned at a relatively safe distance from the electrode rod 3032. Adjusting the gear ratio between the first transmission wheel 5032 and the second transmission wheel 5033 allows for the design of the angle adjustment speed of the electrode rod 3032.

[0076] In a further embodiment, the gear ratio of the first transmission wheel 5032 and the second transmission wheel 5033 is 1:2.

[0077] In some embodiments, such as Figure 4 As shown, there are multiple drive shafts 5031, and the multiple drive shafts 5031 are connected by multiple couplings 15.

[0078] Specifically, such as Figure 4 As shown, there are two drive shafts 5031.

[0079] In some embodiments, such as Figure 1 and Figure 4 As shown, a handwheel 12 is provided at the end of the drive shaft 5031 away from the first drive wheel 5032.

[0080] In one embodiment, such as Figure 1 and Figure 2 As shown, the transmission assembly 503 also includes at least two horizontal adjustment components 6. Each horizontal adjustment component 6 is mounted on the frame 1 along the axial direction of the transmission shaft 5031. The transmission shaft 5031 is rotatably connected to each horizontal adjustment component 6, and each horizontal adjustment component 6 can adjust the transmission shaft 5031 to a horizontal state.

[0081] In this embodiment, the horizontal adjustment component 6 can level the drive shaft 5031. Because the drive shaft 5031 is long, it is impossible to ensure that the drive shaft 5031 remains horizontal, otherwise it will affect the rotation of the drive shaft 5031.

[0082] In some embodiments, such as Figure 2As shown, the horizontal adjustment assembly 6 includes a first plate 601, a second plate 602, a bearing mounting base 603, and a second bearing 604. The second plate 602 is fixed to the first plate 601, and the bearing mounting base 603 is fixed to the second plate 602. The outer ring of the second bearing 604 is fixedly connected to the bearing mounting base 603, and the drive shaft 5031 is fixedly connected to the inner ring of the second bearing 604. The first plate 601 has a first hole 16 and two second holes 17 on both sides along the direction perpendicular to the drive shaft 5031. The fixing plate 102 has a fourth hole corresponding to the first hole 16. The inner walls of the fourth hole and the two second holes 17 are threaded. Bolts pass through the first hole 16 and connect to the fourth hole. There is a gap between the first plate 601 and the fixing plate 102. Two bolts are connected to the two second holes 17 respectively, and the stud ends of the two bolts abut against the fixing plate 102. By adjusting the angle and distance between the first plate and the fixing plate 102, the drive shaft 5031 is adjusted to a horizontal state.

[0083] In one embodiment, such as Figure 2 As shown, it also includes a fixing seat 7, which is fixed on the frame 1. A through hole 11 is provided on the fixing seat 7 along the lifting direction of the drive end 504. The screw 502 passes through the through hole 11 and is rotatably connected to the through hole 11.

[0084] In some embodiments, such as Figure 2 As shown, the fixing base 7 is fixed on the fixing plate 102. The fixing plate 102 has a connecting hole corresponding to the through hole 11. A third bearing 14 is installed in the connecting hole. The outer ring of the third bearing 14 is fixedly connected to the inner wall of the connecting hole, and the inner ring of the third bearing 14 is fixedly connected to the screw 502.

[0085] In one embodiment, such as Figure 6 As shown, it also includes at least one fixing rod 8, one end of which is connected to the frame 1 and the other end is connected to the connecting seat 2.

[0086] In some embodiments, such as Figure 6 As shown, there are four fixing rods 8. One end of each fixing rod 8 is fixedly connected to the connecting seat 2, and the other end is fixedly connected to the fixing plate 102.

[0087] In one embodiment, such as Figure 1 and Figure 3 As shown, it also includes multiple casters 9, which are mounted on the frame 1.

[0088] In this embodiment, it is convenient to move the position of the frame 1.

[0089] In some embodiments, multiple casters 9 are mounted on the frame 101.

[0090] In one embodiment, such as Figure 3As shown, each caster 9 is equipped with a lifting assembly 10.

[0091] In this embodiment, such as Figure 3 As shown, the lifting assembly 10 can adjust the height of the corresponding position of the frame 101 so that the fixed plate 102 remains horizontal and the screw 502 is perpendicular to the fixed plate 102, thereby making the screw 502 vertical and improving the angle setting accuracy of the electrode rod 3032.

[0092] In some embodiments, such as Figure 3 As shown, the lifting assembly 10 includes an adjusting stud 1001 and a mounting plate 1002. The mounting plate 1002 is fixed to the caster 9. The mounting plate 1002 is provided with a fifth hole. The inner wall of the fifth hole is provided with threads. The adjusting stud 1001 is threadedly connected to the fifth hole. One end of the adjusting stud 1001 can abut against the ground to adjust the height of the frame 101.

[0093] The following is an example, combined with Figures 1 to 7 A comprehensive explanation of all the above-mentioned plans is provided.

[0094] The connecting seat 2 is provided with four first hinge parts 201, which are arranged around the circumference of the connecting seat 2 and are equally spaced at angles. The electrode assembly 3 is provided with four, the driving mechanism 5 is provided with four driving ends 504, and the connecting rod 4 is provided with four. The second end of the four connecting rods 4 is respectively hinged to the four driving ends 504, the first end of the four connecting rods 4 is respectively hinged to the third hinge part 305 of the rod 301, and the other end of the four connecting rods 4 is respectively hinged to the four first hinge parts 201.

[0095] The drive unit drives the screw 502 to rotate via the transmission assembly 503. The rotation of the screw 502 causes the connecting block 501 to move along the screw 502. When the connecting block 501 moves downward along the screw 502, the connecting rod 4 rotates and moves downward. The first end of the connecting rod 4 is hinged to the third hinge part 305 of the connecting rod 301, driving the connecting rod 301 to rotate about the second hinge part 304 in a direction away from the screw 502. This adjusts the angle between the electrode rod 3032 connected to the connecting rod 301 and the screw 502. At the same time, it adjusts the angle between two adjacent electrode rods 3032 or two opposing electrode rods 3032.

[0096] The drive unit drives the transmission shaft 5031 to rotate. The transmission shaft 5031 is connected to the first transmission wheel 5032 and the second transmission wheel 5033, which in turn drives the screw 502 to rotate. Both the first transmission wheel 5032 and the second transmission wheel 5033 are bevel gears, which can change the transmission direction and adjust the length of the transmission shaft 5031 to ensure that the operator is at a relatively safe distance from the electrode rod 3032. Adjusting the gear ratio between the first transmission wheel 5032 and the second transmission wheel 5033 allows for the design of the angle adjustment speed of the electrode rod 3032.

[0097] Four electrode rods 3032 are set up to simultaneously meet the testing of DC and three-phase AC power. When DC power testing is required, two adjacent electrode rods 3032 or two diagonally opposite electrode rods 3032 can be connected. When three-phase AC power is required, three electrode rods 3032 can be connected.
