TECHNICAL FIELD

[0001] The present application relates to the technical field of electric spark test, and particularly relates to an electric spark test device facilitating replacement of copper wires. BACKGROUND

[0002] To explore the generation and collapse process of underwater vaporization bubble, an electric spark test device can be used. Generally, the electric spark test device comprises two electrodes and two copper wires. The two electrodes are used to electrify the two copper wires, so that an electric spark is generated between the two copper wires to form a steam bubble.

[0003] For example, the application No. CN201610495983.X discloses a research device for thermal effect of vaporization bubble. Two electrodes are suspended and fixed above a water tank by an electrode support and are inserted into the water tank. The bottom end of each electrode is connected to a copper wire. The non-connected end of each copper wire does not contact each other, so that an electric spark is generated between the end points of the two copper wires. The water around the electric spark is rapidly heated and vaporized. Since the energy generated by the electric spark is high and the position is concentrated, the generated steam bubble is basically spherical.

[0004] The melting point of copper is about 1083°C, which is much higher than the temperature of the discharge gap. However, repeated high-temperature heating and rapid cooling of water (thermal shock) can cause the copper wire material to fatigue, become brittle, and change the intergranular structure, thereby greatly reducing its strength and leading to breakage under tension. Therefore, the copper wire needs to be frequently replaced in the electric spark test.

[0005] However, in the electric spark test, manual replacement of the copper wire is time-consuming and laborious, which affects the test process. SUMMARY

[0006] Therefore, it is necessary to provide an electric spark test device facilitating replacement of copper wires, so as to solve the problem that manual replacement of the copper wire is time-consuming and laborious, which affects the test process in the electric spark test.

[0007] The application provides an electric spark test device with copper wires convenient to replace, which comprises at least two copper wires, at least two electrodes, a water tank, at least two guide blocks, at least two wire cutting assemblies, a wire feeding assembly and an electric control device.

[0008] Further, the copper wire channel is arranged obliquely downward, and the electrode channel is arranged vertically, and the bottom end of the electrode channel is communicated with the part of the second channel of the copper wire channel close to the first channel.

[0009] Further, the first channel is a square channel, the length and width of the square channel are matched with the diameter of the copper wire, and the second channel is a circular channel, the inner diameter of the circular channel is matched with the diameter of the copper wire, so that the cutting end of the wire cutting assembly can cut off the end of the first channel close to the second channel.

[0010] Further, the wire cutting assembly comprises a cutting knife and a driving member, the cutting knife is slidably and sealingly connected with the knife entry hole of the guide block, the knife entry hole is communicated with the wire cutting channel, the cutting knife can slide to a first position and a second position, when the cutting knife slides to the first position, the cutting end of the cutting knife is located in the copper wire channel and divides the copper wire channel into the first channel and the second channel, when the cutting knife slides to the second position, the cutting knife is completely located in the knife entry hole, the driving member is installed in the water tank, the output end of the driving member is connected with the cutting knife, and the driving member is used for driving the cutting knife to reciprocate between the first position and the second position.

[0011] Further, the wire cutting assembly further comprises a first guide column, the first guide column connects the cutting knife and the output end of the driving member, the outer wall of the first guide column is provided with a sealing ring, and the first guide column is slidably and sealingly connected with the knife entry hole.

[0012] Further, the wire cutting assembly further comprises a positioning member, the positioning end of the positioning member is arranged in the second channel and elastically abuts against the copper wire in the second channel.

[0013] Furthermore, the wire-cutting assembly also includes a limiting member that connects the electrode and the guide block, allowing the electrode to move relative to the guide block toward the second channel.

[0014] Furthermore, the wire feeding assembly includes a take-up roller and a wire feeding roller assembly, both of which are fixedly connected to the water tank. One end of the copper wire is connected to the take-up roller and wound around the take-up roller. The other end of the copper wire passes through the wire feeding gap of the wire feeding roller assembly and the copper wire channel in sequence, and emerges from the bottom of the copper wire channel.

[0015] Furthermore, the wire feeding roller assembly includes two wire feeding rollers and a motor arranged opposite to each other. The two wire feeding rollers are rotatably connected to the water tank, and the wire feeding gap is formed between the two wire feeding rollers. The motor is mounted on the water tank, and the output end of the motor is connected to one of the wire feeding rollers.

[0016] Furthermore, the wire feeding assembly also includes a wire guide drum, which is fixedly connected to the water tank, and the portion of the copper wire located between the take-up roller and the guide block passes through the wire guide drum.

[0017] Compared with existing technologies, this method involves passing two copper wires through the copper wire channels of two conductive blocks. The cutting end of the corresponding wire-cutting assembly cuts the copper wires in the copper wire channels. The ends of the two copper wires extending outside the second channel do not contact each other, and the interval is less than the breakdown distance of the electric spark. The electrode extends from the electrode channel into the second channel and abuts against the corresponding copper wire. The controller supplies power to the electrode, thereby forming an electric spark. When replacing the copper wire, the wire feeding mechanism feeds the copper wire into the first channel. The copper wire in the first channel pushes out the copper wire in the second channel and replaces it. The cutting end of the wire-cutting assembly cuts the copper wire, thus completing the copper wire replacement process. This automatic copper wire replacement saves time and effort.
