DETAILED DESCRIPTION
[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0022] according to Figure 1 , 2 As shown in , 3 and 4, an arc generator is proposed in this embodiment, comprising a fixing seat 4, a support rod 5 and an arc generating module 6, a first electrode 1 is provided at the lower end of the fixing seat 4, a support rod 5 is provided at the front of the fixing seat 4, a second electrode 7 is provided at the lower end of the support rod 5, the second electrode 7 is placed on one side of the first electrode 1, and the arc generating module 6 is fixedly connected to the outer side of the support rod 5;
[0023] The arc generating module 6 mainly includes a low-voltage arc circuit, a high-voltage high-frequency ignition circuit, and a transformer, among which the low-voltage arc circuit is the basic part of the arc generator, which is used to pass the current through the electrode at a relatively low voltage to generate an arc, ensuring that the electrodes can maintain a stable current conduction. The high-voltage high-frequency ignition circuit is responsible for generating a high-voltage high-frequency current between the second electrode 7 and the first electrode 1 to ignite the arc. The transformer is responsible for converting the high voltage of the power supply into a voltage level suitable for work to meet the electrical energy conditions required for the arc to occur.
[0024] In order to prevent the arc from climbing up along the second electrode 7, an insulating sheath 8 is provided between the arc generation module 6 and the second electrode 7, and the insulating sheath 8 is sleeved on the outside of the support rod 5 and is detachably connected to the support rod 5; when an arc is generated between the first electrode 1 and the second electrode 7, the insulating sheath 8 can prevent the arc from climbing up along the support rod 5, and protect the arc generation module 6 and the electric control module provided on the fixing seat 4. The detachable connection mode also facilitates the staff to replace the insulating sheath 8.
[0025] An adjusting seat 2 is arranged above the fixing seat 4, and the adjusting seat 2 is rotatably connected to the fixing seat 4 through a rotating shaft 3. A rotation control mechanism for controlling the rotation of the fixing seat 4 is arranged inside the adjusting seat 2. The fixing seat 4 is rotatably connected to the adjusting seat 2, and the direction of the fixing seat 4 can be adjusted, which has better flexibility.
[0026] Specifically, the rotation control mechanism includes a worm 10, a worm wheel 11 and a motor 9. The worm 10 and the worm wheel 11 are both placed in the adjusting seat 2. The worm wheel 11 is fixedly connected to the upper end of the fixed seat 4 through the rotating shaft 3. The rotating shaft 3 is rotatably connected to the adjusting seat 2. The worm 10 is placed on one side of the worm wheel 11 and meshes with the worm wheel 11. The motor 9 is installed on the outside of the adjusting seat 2, and the output end of the motor 9 is fixedly connected to the upper end of the worm 10.
[0027] The motor 9 drives the worm 10 to rotate, and the worm 10 meshes with the worm wheel 11 to drive the worm wheel 11 to rotate. When the worm wheel 11 rotates, the fixed seat 4 fixed to the worm wheel 11 through the rotating shaft 3 will also rotate to adjust the direction of the second electrode 7 on the fixed seat 4. The worm gear transmission has a self-locking property. When the worm 10 stops rotating, the rotating shaft 3 will not rotate under the meshing of the teeth between the worm 10 and the worm wheel 11, thereby ensuring the stability of the arc generator during use.
[0028] In order to facilitate the staff to replace the support rod 5, the support rod 5 is fixed to the fixing seat 4 in a detachable connection manner. Specifically, a flange is provided on the upper end of the support rod 5, and a plurality of fixing bolts are assembled on the flange. The fixing bolts pass through the flange and are threadedly connected with the threaded holes opened on the outer side of the fixing seat 4. When removing the support rod 5 from the fixing seat 4, the fixing bolts on the flange can be screwed out of the threaded holes.
[0029] About Insulating Sheath 8:
[0030] The insulating sheath 8 includes two ceramic half-sleeves 81 that are aligned with each other. The two ceramic half-sleeves 81 are inserted on the outside of the support rod 5. The outer wall of the ceramic half-sleeves 81 is provided with a plurality of ceramic discs 82 that are superimposed on each other. The ceramic discs 82 on the two ceramic half-sleeves 81 are aligned with each other. A bolt positioning member is provided between the two ceramic half-sleeves 81 to fix the two ceramic half-sleeves 81 in the aligned state. The insulating sheath 8 is a split structure design. When the insulating sheath 8 is removed from the support rod 5, the bolt positioning member is released to fix the two ceramic half-sleeves 81, and the two ceramic half-sleeves 81 can be directly removed from both sides of the support rod 5.
[0031] After the two ceramic half-shells 81 are matched, the ceramic discs 82 will also match each other, and a wavy curved surface structure is formed between the ceramic discs 82, which can effectively reduce the occurrence of creepage.
[0032] It should be further explained that the bolt positioning member includes a bolt seat 85, which is fixedly connected to both sides of the ceramic half-casing 81, and a positioning bolt 86 is mounted on the bolt seat 85. The bolt seat 85 is provided with a through hole that is threadedly matched with the positioning bolt 86. After the two ceramic half-casings 81 are aligned, the bolt seats 85 on both sides of the ceramic half-casings 81 will also be aligned with each other, and the positioning bolt 86 is screwed into them, so that the two bolt seats 85 and the two ceramic half-casings 81 can be fixed.
[0033] In order to improve the fit of the two ceramic discs 82 after being matched, in a preferred embodiment, a concave-convex matching structure is provided on the side of the two ceramic half-shells 81 close to each other, and the concave-convex matching structure includes a slot 83 and a positioning protrusion 84, and the slot 83 is plugged and matched with the positioning protrusion 84. After the two ceramic half-shells 81 are matched with each other, the positioning protrusion 84 on one ceramic half-shell 81 will be inserted into the slot 83 provided on the other ceramic half-shell 81, so as to enhance the tightness and fit between the ceramic half-shells 81 and the ceramic discs 82.
[0034] How this application works:
[0035] The arc generating module 6 is started, and an arc is generated between the first electrode 1 and the second electrode 7. When an arc is generated between the first electrode 1 and the second electrode 7, the insulating sheath 8 sleeved on the outside of the support rod 5 prevents the arc from climbing up along the support rod 5, thereby protecting the arc generating module 6 and the electric control module arranged on the fixing seat 4. The detachable connection mode of the insulating sheath 8 facilitates the staff to replace the insulating sheath 8. The fixing seat 4 is rotatably connected to the adjustment seat 2, and the direction of the fixing seat 4 can be adjusted, which has better flexibility.
