[0048] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0049] Example 1

[0050] This embodiment provides a high-power electric spark source transmitting probe, including a first electrode 1, a second electrode 2, a first insulating component 3, a second insulating component 4, a discharge ring 5, and a locking component 6.

[0051] The first electrode 1 is a cylindrical structure with one end open;

[0052] For example, see Figure 1-2 The first electrode 1 is a stainless steel cylinder with an opening at the right end.

[0053] The first insulating element 3 is disposed inside the first electrode 1;

[0054] For example, see Figure 2 The first insulating element 3 is a tubular structure and is coaxially fixed on the inner wall of the first electrode 1.

[0055] The second electrode 2 is sleeved inside the first insulating member 3, and the first end of the second electrode 2 extends to the outside of the opening of the first electrode 1.

[0056] For example, see Figure 2 The second electrode 2 is a rod-shaped structure. The second electrode 2 is coaxially fixed inside the first insulating member 3, and the right end of the second electrode 2 extends to the outside of the right end opening of the first electrode 1.

[0057] The discharge ring 5 is sleeved on the outside of the first end of the second electrode 2;

[0058] For example, see Figure 2 The discharge ring 5 is located to the right of the first electrode 1, and is coaxially sleeved on the outside of the right end of the second electrode 2. The discharge ring 5 is coaxial with the first electrode 1, and the outer diameter of the discharge ring 5 is the same as that of the first electrode 1.

[0059] The second insulating element 4 is clamped between the discharge ring 5 and the first electrode 1;

[0060] For example, see Figure 2The second insulating element 4 is a ring structure. The second insulating element 4 is coaxially sleeved on the outside of the second electrode 2 and is clamped between the discharge ring 5 and the first electrode 1.

[0061] The locking component 6 is used to lock the discharge ring 5 and the second insulating component 4 to the outlet of the first electrode 1. The first electrode 1 is filled with high-voltage insulating glue.

[0062] For example, see Figure 1-2 The second electrode 2 has an external thread on its right end, and the locking member 6 is a nut that is threadedly connected to the second electrode 2. The locking member 6 locks the discharge ring 5 and the second insulating member 4 at the right end outlet of the first electrode 1. Simultaneously, the first electrode 1 is filled with high-voltage insulating adhesive, which serves to bond the second electrode 2, the first insulating member 3, and the first electrode 1, effectively improving electrode stability. Furthermore, the high-voltage insulating adhesive (such as epoxy resin insulating adhesive or acrylic adhesive) has strong adhesion, corrosion resistance, and waterproof and moisture-proof properties.

[0063] Based on the above structure, the high-power electric spark source transmitting probe provided in this embodiment uses the first electrode 1 as the cathode connecting cable and the second electrode 2 as the anode connecting cable. After energization, the discharge ring 5 can discharge to the right end of the first electrode 1 to generate an electric arc, vaporizing the water to form an elastic wave. After the discharge is completed, the second insulating component 4 and the discharge ring 5 may be damaged by high temperature and high pressure impact. At this time, by unscrewing the locking component 6 from the right end of the second electrode 2, the second insulating component 4 and the discharge ring 5 can be disassembled from the outlet of the first electrode 1, allowing for quick replacement of the second insulating component 4 and the discharge ring 5. The operation is simple and convenient. At the same time, filling the first electrode 1 with high-voltage insulating glue not only improves the stability of the second electrode 2, but also prevents current leakage, short circuits, or electric arc discharge from occurring inside the first electrode 1.

[0064] Based on the above technical solution, in the technical solution provided in this embodiment, a limiting platform 11 is provided on the inner wall of the opening end of the first electrode 1, and the second insulating member 4 is clamped between the limiting platform 11 and the discharge ring 5, and there is a gap between the discharge ring 5 and the opening end of the first electrode 1.

[0065] For example, see Figure 2 An annular limiting platform 11 is coaxially fixed on the inner wall of the right end of the first electrode 1. The second insulating member 4 has an annular structure and is adapted to the first electrode 1. The left end of the second insulating member 4 is embedded in the opening at the right end of the first electrode 1, and the left end of the second insulating member 4 abuts against the right end of the limiting platform 11. The outer wall of the second insulating member 4 abuts against the inner wall of the first electrode 1, and the inner wall of the second insulating member 4 abuts against the outer wall of the second electrode 2. The left end of the discharge ring 5 abuts against the second insulating member 4, and the left end of the discharge ring 5 is spaced a certain distance from the right end of the first electrode 1. At the same time, the discharge ring 5 is electrically connected to the second electrode 2, thereby forming high-voltage discharge conditions.

[0066] Furthermore, the limiting platform 11 has a ring structure. The end of the first insulating member 3 near the opening of the first electrode 1 is embedded inside the limiting platform 11. A stop ring 12 is sleeved on the outside of the first insulating member 3. The end of the stop ring 12 near the opening of the first electrode 1 abuts against the limiting platform 11.

[0067] For example, see Figure 2 The outer wall of the first insulating member 3 abuts against the inner wall of the limiting platform 11, and the inner wall of the first insulating member 3 abuts against the outer wall of the second electrode 2, thereby sealing the opening at the right end of the first electrode 1. The outer wall of the stop ring 12 abuts against the inner wall of the first electrode 1, which not only improves the stability of the first insulating member 3, but also prevents the first insulating member 3 from moving to the right.

[0068] In the technical solution provided in this embodiment, the first electrode 1 may be provided with a glue inlet 13 and an air outlet 14 on its side wall.

[0069] For example, see Figure 3 The inlet 13 is used to add high-voltage insulating adhesive, and the outlet 14 is used to connect to a vacuum device. While adding the high-voltage insulating adhesive, a vacuum is created by the vacuum device, allowing the high-voltage insulating adhesive to flow fully into the first electrode 1 and fill the entire first electrode 1, ensuring the stability and insulation of the internal structure of the first electrode 1.

[0070] Both the glue inlet 13 and the air outlet 14 are tubular structures, and both are provided with external threads. Each of the glue inlet 13 and the air outlet 14 is screwed with a cap. After the high-voltage insulating adhesive has been added, the glue inlet 13 and the air outlet 14 can be sealed with the caps, making the operation simple and convenient.

[0071] In the technical solution provided in this embodiment, the second end of the second electrode 2 is electrically connected to the power transmission component 7, and the first electrode 1 has a mounting hole at the end facing away from the opening. The mounting hole is used for the power transmission component 7 to enter and exit.

[0072] For example, see Figure 2 The left end of the second electrode 2 is electrically connected to two power transmission components 7. The left end of the first electrode 1 has two mounting holes, which correspond one-to-one with the power transmission components 7. The mounting holes are used for the corresponding power transmission components 7 to enter and exit, that is, the left end of the power transmission component 7 extends to the outside of the first electrode 1 through the corresponding mounting hole. The power transmission component 7 is a cable, used to realize the electrical connection.

[0073] Among them, the power transmission component 7 can be fixedly fitted with a cable sheath 8, which passes through the mounting hole and serves to protect the cable.

[0074] A waterproof sleeve 9 can be installed between the cable sheath 8 and the mounting hole. The waterproof sleeve 9 can improve the waterproofness of the mounting hole and prevent water from seeping into the electrode through the mounting hole, which could lead to equipment corrosion.

[0075] A waterproof ring 10 is fixedly fitted on the outer side of the waterproof sleeve 9, and the waterproof ring 10 is attached to the right end of the first electrode 1. The waterproof ring 10 can further enhance the waterproofness at the mounting hole.

[0076] Example 2

[0077] During operation, the greater the required discharge power, the more power transmission components 7 need to be connected to the second electrode 2. The appropriate number of cables should be selected according to the actual situation.

[0078] For example, the left end of the second electrode 2 can also be electrically connected to three power transmission components 7 at the same time. The left end of the corresponding first electrode 1 is provided with three mounting holes, which correspond one-to-one with the power transmission components 7. The mounting holes are used for the corresponding power transmission components 7 to enter and exit, that is, the left end of the power transmission component 7 extends to the outside of the first electrode 1 through the corresponding mounting hole.

[0079] However, when the number of power transmission components 7 is different, the corresponding number of mounting holes is also different. In this case, it is necessary to replace the entire first electrode 1 and select a first electrode 1 with an appropriate number of mounting holes; otherwise, some mounting holes will be empty. This not only easily leads to material waste, but also requires carrying multiple first electrodes 1, resulting in a large overall weight and transportation difficulties.

[0080] To address the aforementioned issues, in the technical solution provided in this embodiment, the end plate of the first electrode 1 facing away from the opening is a detachable structure.

[0081] For example, see Figure 4-5 The first electrode 1 includes a tube body and an end plate 15. A through hole 16 is provided on the end plate 15, and a screw hole is provided at the left end of the tube body. The screw hole is aligned with the through hole 16. A locking bolt 17 passes through the through hole 16 and is screwed into the screw hole, thus locking the end plate 15 to the tube body. This makes assembly and disassembly very convenient. When the number of power transmission components 7 to be connected differs from the number of mounting holes, the end plate 15 can be directly replaced without replacing the entire first electrode 1. Furthermore, the overall weight is light, making it very convenient to carry and transport.

[0082] To improve the sealing performance between the end plate 15 and the pipe body, a sealing gasket is sandwiched between the end plate 15 and the pipe body. The sealing gasket can prevent water from entering the pipe body through the through hole 16 or the gap between the end plate 15 and the pipe body, thereby improving the sealing performance between the end plate 15 and the pipe body.

[0083] It should be noted that the area on the sealing gasket corresponding to the through hole 16 has a perforation for the locking bolt 17 to pass through.

[0084] To improve the stability of end plate 15 and tube body, see Figure 6The outer diameter of the end plate 15 is larger than that of the pipe body. An annular groove adapted to the pipe body is provided on the right end face of the end plate 15. The left end of the pipe body is embedded in the annular groove, and the through hole 16 is located within the annular groove area. By embedding the left end of the pipe body into the annular groove, and then screwing the locking bolt 17 through the through hole 16 and into the screw hole, the end plate 15 and the pipe body can be locked and fixed. The annular groove can limit the movement of the pipe body, effectively improving the stability of the end plate 15 and the pipe body, thereby extending the service life of the equipment and preventing damage caused by high-pressure impacts.

[0085] A sealing gasket can be provided on the inner wall of the annular groove to effectively improve the sealing performance between the annular groove and the pipe body.
