Description

Technical Field

[0001] The present disclosure relates to the field of discharge technology, and in particular to a discharge device. Background Art

[0002] At present, when discharging high-capacitance withstand voltage test specimens, the test power supply must be disconnected after the high-voltage test is completed, and the charge on the specimen is used to discharge itself to the ground through the voltage multiplier and the specimen itself. When the voltmeter drops to about 5 to 15 kV, the operator holds a discharge rod and gradually approaches the specimen for free discharge. As the voltage decreases, the discharge rod gradually approaches, and the tip of the discharge rod can touch the specimen to allow the specimen to discharge directly to the ground.

[0032] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and are not to be construed as limitations of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0033] like Figure 1 As shown, the embodiment of the present disclosure proposes a discharge device, including: a base 1, a loading platform 2, a first driving mechanism 3, a discharge rod 4 and a linkage mechanism 5, the loading platform 2 is slidably arranged on the base 1 in the vertical direction, the first driving mechanism 3 is used to drive the loading platform 2 to rise and fall, the discharge rod 4 is slidably arranged in the loading platform 2 in the horizontal direction, and the discharge rod 4 is grounded, the discharge rod 4 is used for discharging the target sample, and the linkage mechanism 5 is arranged between the discharge rod 4 and the loading platform 2. When the loading platform 2 descends, the linkage mechanism 5 abuts against the base 1 and drives the discharge rod 4 to move in the horizontal direction, so that the discharge end of the discharge rod 4 moves into the loading platform 2; when the loading platform 2 rises, the linkage mechanism 5 moves away from the base 1 and drives the discharge rod 4 to move in the horizontal direction, so that the discharge end of the discharge rod 4 moves out of the loading platform 2.

[0034] It can be understood that when the first driving mechanism 3 drives the loading platform 2 to rise, the linkage mechanism 5 moves away from the base 1 and drives the discharge rod 4 to move in the horizontal direction, so that the discharge end of the discharge rod 4 moves out of the loading platform 2, thereby utilizing the discharge rod 4 to achieve discharge of the target sample. At the same time, the position of the discharge rod 4 can also be regulated by utilizing the drive of the first driving mechanism 3. Moreover, when the first driving mechanism 3 drives the loading platform 2 to descend, the linkage mechanism 5 abuts against the base 1 and drives the discharge rod 4 to move in the horizontal direction, so that the discharge end of the discharge rod 4 moves into the loading platform 2, thereby achieving storage of the discharge rod 4.

[0035] Therefore, through the cooperation of the first driving mechanism 3 and the linkage mechanism 5, the discharge rod 4 can be extended and stored, and the discharge position can be accurately adjusted, thereby effectively improving the discharge efficiency and discharge quality of the discharge rod 4 and avoiding the risk of electric shock caused by manual operation.

[0036] It should be noted that the base 1 is used to carry components such as the loading platform 2 and the first driving mechanism 3. The specific type of the base 1 can be set according to actual needs and is not limited to this. For example, the base 1 can be a base structure that is close to a rectangle.

[0037] The loading platform 2 is used to carry the discharge rod 4 and other components. The specific type of the loading platform 2 can be set according to actual needs and is not limited to this. For example, the loading platform 2 can be a pedestal structure that is close to a rectangle.

[0038] The first driving mechanism 3 is used to drive the loading platform 2 to rise and fall. The specific type of the first driving mechanism 3 can be set according to actual needs and is not limited to this. For example, the first driving mechanism 3 can be a plurality of electric push rods, a plurality of hydraulic cylinders, or a plurality of air cylinders.

[0039] The discharge rod 4 is used for free discharge and direct discharge of the target sample. The specific type of the discharge rod 4 can be set according to actual needs and is not limited. After the discharge rod 4 is grounded, the discharge end of the discharge rod 4 is close to the target sample for free discharge, and the discharge end of the discharge rod 4 contacts the target sample for direct discharge.

[0040] The linkage mechanism 5 is used for the linkage between the discharge rod 4 and the loading platform 2. Specifically, when the loading platform 2 descends, the linkage mechanism 5 abuts against the base 1 and drives the discharge rod 4 to move in the horizontal direction, so that the discharge end of the discharge rod 4 moves into the loading platform 2, thereby avoiding the discharge rod 4 from being always exposed to the outside, solving the problem that the discharge rod 4 is easily damaged by external physical impact, friction, etc. during movement and storage, affecting the normal discharge function and service life, protecting the discharge rod 4, extending the service life of the discharge rod 4, and improving the reliability of the discharge device; when the loading platform 2 rises, the linkage mechanism 5 moves away from the base 1 and drives the discharge rod 4 to move in the horizontal direction, so that the discharge end of the discharge rod 4 moves out of the loading platform 2, thereby eliminating the need for an additional complex control system and simplifying the operation process of the discharge rod 4.

[0041] The specific type of the linkage mechanism 5 can be set according to actual needs and is not limited thereto.

[0042] like Figure 2As shown, in some embodiments, the linkage mechanism 5 includes: a first sliding cavity 51, a second sliding cavity 52, a contact plate 53 and at least one return spring 54. The first sliding cavity 51 is arranged in the loading platform 2 along the horizontal direction, and the end of the discharge rod 4 away from the discharge end is slidably arranged in the first sliding cavity 51 along the horizontal direction and forms a first linkage cavity with the cavity bottom of the first sliding cavity 51, the second sliding cavity 52 is arranged in the loading platform 2 along the vertical direction, and one end of the contact plate 53 is arranged opposite to the base 1, and the end of the contact plate 53 away from the base 1 is slidably arranged in the second sliding cavity 52 along the vertical direction and forms a second linkage cavity with the cavity bottom of the second sliding cavity 52, and the return spring 54 is arranged in the second linkage cavity. The first linkage cavity and the second linkage cavity shrink and expand synchronously, and when the loading platform 2 descends, the contact plate 53 abuts against the base 1 and shrinks the second linkage cavity, and when the loading platform 2 rises, the contact plate 53 is away from the base 1 and expands the second linkage cavity.

[0043] It can be understood that since the first sliding cavity 51 is arranged in the loading platform 2 along the horizontal direction, and the end of the discharge rod 4 away from the discharge end is slidably arranged in the first sliding cavity 51 along the horizontal direction and forms a first linkage cavity with the cavity bottom of the first sliding cavity 51, when the first linkage cavity is filled with gas, the discharge end of the discharge rod 4 can slide in the horizontal direction and move out of the loading platform 2, and when the gas is discharged from the first linkage cavity, the discharge end of the discharge rod 4 can slide in the horizontal direction and move into the loading platform 2.

[0044] Since the second sliding cavity 52 is arranged in the loading platform 2 along the vertical direction, and one end of the contact plate 53 is arranged opposite to the base 1, the end of the contact plate 53 away from the base 1 is slidably arranged in the second sliding cavity 52 along the vertical direction and forms a second linkage cavity between the cavity bottom of the second sliding cavity 52, so that when the contact plate 53 moves away from the base 1, the end of the contact plate 53 away from the base 1 can slide in the vertical direction and fill the second linkage cavity with gas, and, when the contact plate 53 abuts against the base 1, the end of the contact plate 53 away from the base 1 can slide in the vertical direction and discharge the gas from the second linkage cavity.

[0045] Since the first linkage chamber and the second linkage chamber contract and expand synchronously, when the loading platform 2 descends, the abutment plate 53 abuts against the base 1 and causes the second linkage chamber to exhaust gas and contract, thereby driving the first linkage chamber to exhaust gas and contract, thereby realizing the storage of the discharge rod 4; and, when the loading platform 2 rises, the abutment plate 53 moves away from the base 1 and causes the second linkage chamber to be filled with gas and expand, thereby driving the first linkage chamber to be filled with gas and expand, thereby realizing the extension of the discharge rod 4.

[0046] It should be noted that the first sliding cavity 51 is used for the sliding arrangement of the discharge rod 4 in the loading platform 2. The specific type of the first sliding cavity 51 can be set according to actual needs and is not limited thereto. For example, the first sliding cavity 51 is arranged in the loading platform 2 along the horizontal direction, and the end of the first sliding cavity 51 away from the first linkage cavity penetrates the loading platform 2, and the discharge rod 4 is slidably arranged in the first sliding cavity 51 from the end of the first sliding cavity 51 away from the first linkage cavity. Among them, the end of the discharge rod 4 located in the first sliding cavity 51 close to the first linkage cavity can be slidably arranged by a circular plate, and is limited by a limiting ring located at the end of the first sliding cavity 51 away from the first linkage cavity.

[0047] The second sliding cavity 52 is used for the sliding arrangement of the contact plate 53 on the loading platform 2. The specific type of the second sliding cavity 52 can be set according to actual needs, and there is no limitation on this. For example, the second sliding cavity 52 is arranged in the extrusion box at the bottom of the loading platform 2 along the vertical direction, and the end of the second sliding cavity 52 away from the second linkage cavity passes through the extrusion box, and the connecting plate arranged on the contact plate 53 is slidably arranged in the second sliding cavity 52 from the end of the second sliding cavity 52 away from the second linkage cavity. Among them, the connecting plate is located at the end of the second sliding cavity 52 close to the second linkage cavity and can be slidably arranged by using the piston plate.

[0048] The abutment plate 53 is used to cooperate with the base 1 to realize the linkage between the discharge rod 4 and the first driving mechanism 3. The specific type of the abutment plate 53 can be set according to actual needs and is not limited to this. For example, the abutment plate 53 is a plate structure, and the abutment plate 53 is located at the bottom of the loading platform 2, that is, above the base 1.

[0049] The reset spring 54 is used to reset the contact plate 53, so that when the contact plate 53 is away from the base 1, the second linkage cavity can be inflated and expanded, thereby extending the discharge rod 4. The specific type of the reset spring 54 can be set according to actual needs and is not limited to this. For example, the reset spring 54 is a coil spring, and multiple reset springs 54 are evenly distributed between the contact plate 53 and the bottom of the second sliding cavity 52.

[0050] like Figure 2 As shown, in some embodiments, the linkage mechanism 5 further includes: a first piston assembly 55, a second piston assembly 56 and a U-shaped plate 57. The cylinder end of the first piston assembly 55 is connected to the first linkage chamber, and the cylinder end of the second piston assembly 56 is connected to the second linkage chamber. The U-shaped plate 57 is slidably arranged on the loading platform 2 in the horizontal direction, and one end of the U-shaped plate 57 is connected to the piston end of the first piston assembly 55, and one end of the U-shaped plate 57 away from the first piston assembly 55 is connected to the piston end of the second piston assembly 56.

[0051] It can be understood that since the cylinder end of the first piston assembly 55 is connected to the first linkage chamber, the first linkage chamber and the cylinder end of the first piston assembly 55 can shrink and expand synchronously; since the cylinder end of the second piston assembly 56 is connected to the second linkage chamber, the second linkage chamber and the cylinder end of the second piston assembly 56 can shrink and expand synchronously; since one end of the U-shaped plate 57 is connected to the piston end of the first piston assembly 55, and the end of the U-shaped plate 57 away from the first piston assembly 55 is connected to the piston end of the second piston assembly 56, the first piston assembly 55 and the second piston assembly 56 can achieve synchronous shrinkage and expansion using the U-shaped plate 57.

[0052] Therefore, when the loading platform 2 descends, the contact plate 53 abuts against the base 1 and causes the second linkage chamber to contract, and then the first piston assembly 55 and the second piston assembly 56 are linked to achieve the storage of the discharge rod 4; when the loading platform 2 rises, the contact plate 53 moves away from the base 1 and causes the second linkage chamber to expand, and then the first piston assembly 55 and the second piston assembly 56 are linked to achieve the extension of the discharge rod 4.

[0053] It should be noted that the rising of the loading platform 2 synchronously drives the discharge rod 4 to extend, and no additional complex control system is required, which simplifies the operation process, has high stability and reliability, improves the convenience and safety of using the discharge device, and can also save energy to a certain extent. When the device is used, the discharge platform descends and resets, and the discharge rod 4 is re-stored into the loading platform 2 to prevent the discharge rod 4 from being bumped during the movement and storage process, thereby increasing the service life of the discharge rod 4.

[0054] The cylinder end of the first piston assembly 55 is connected to the first linkage chamber. When the first linkage chamber is inflated, the piston end of the first piston assembly 55 extends. When the first linkage chamber is deflated and contracts, the piston end of the first piston assembly 55 retracts. The specific type of the first piston assembly 55 can be set according to actual needs and is not limited to this.

[0055] The cylinder end of the second piston assembly 56 is connected to the second linkage chamber. When the second linkage chamber is inflated, the piston end of the second piston assembly 56 extends. When the second linkage chamber is deflated and contracts, the piston end of the second piston assembly 56 retracts. The specific type of the second piston assembly 56 can be set according to actual needs and is not limited to this.

[0056] The U-shaped plate 57 is used for the linkage between the first piston assembly 55 and the second piston assembly 56. The specific type of the U-shaped plate 57 can be set according to actual needs and is not limited thereto. The first piston assembly 55 and the second piston assembly 56 are arranged in parallel, and the first piston assembly 55 and the second piston assembly 56 have the same telescopic direction.

[0057] like Figure 2As shown, in some embodiments, the first piston assembly 55 includes: a first piston chamber 551, a first piston column 552 and a first piston rod 553. The first piston chamber 551 is horizontally arranged in the loading platform 2, and the first piston column 552 is horizontally slidably arranged in the first piston chamber 551, one end of the first piston rod 553 is connected to the first piston column 552, one end of the first piston rod 553 away from the first piston column 552 extends out of the first piston chamber 551 and is connected to one end of the U-shaped plate 57 away from the second piston assembly 56, and one end of the first piston chamber 551 away from the first piston rod 553 is connected to the first linkage chamber.

[0058] It can be understood that when the U-shaped plate 57 moves in a direction close to the loading platform 2, the end of the U-shaped plate 57 away from the second piston assembly 56 drives the first piston rod 553 and the first piston column 552 to move synchronously, thereby driving the exhaust contraction of the first piston chamber 551 and the inflation expansion of the first linkage chamber, thereby achieving the extension of the discharge rod 4; when the U-shaped plate 57 moves in a direction away from the loading platform 2, the end of the U-shaped plate 57 away from the second piston assembly 56 drives the first piston rod 553 and the first piston column 552 to move synchronously, thereby driving the inflation expansion of the first piston chamber 551 and the exhaust contraction of the first linkage chamber, thereby achieving the contraction of the discharge rod 4.

[0059] like Figure 2 As shown, in some embodiments, the second piston assembly 56 includes: a second piston chamber 561, a second piston column 562 and a second piston rod 563. The second piston chamber 561 is horizontally arranged on the loading platform 2, and the second piston column 562 is horizontally slidably arranged in the second piston chamber 561, one end of the second piston rod 563 is connected to the second piston column 562, one end of the second piston rod 563 away from the second piston column 562 extends out of the second piston chamber 561 and is connected to one end of the U-shaped plate 57 away from the first piston assembly 55, and one end of the second piston chamber 561 away from the second piston rod 563 is connected to the second linkage chamber.

[0060] It can be understood that when the second linkage chamber is inflated and expanded, the second piston chamber 561 is exhausted and contracted, thereby driving the second piston column 562 and the second piston rod 563 to move synchronously, and then driving the U-shaped plate 57 to move in the direction close to the loading platform 2; when the second linkage chamber is exhausted and contracted, the second piston chamber 561 is inflated and expanded, thereby driving the second piston column 562 and the second piston rod 563 to move synchronously, and then driving the U-shaped plate 57 to move in the direction away from the loading platform 2.

[0061] like Figure 2As shown, in some embodiments, the linkage mechanism 5 also includes: a slide rod 58 and a slider 59, a guide groove is provided at one end of the U-shaped plate 57 away from the first piston assembly 55, and the slide rod 58 is arranged in the guide groove along the horizontal direction, the slider 59 is arranged on the loading platform 2, and the end of the slider 59 away from the loading platform 2 extends into the guide groove and is slidably sleeved on the slide rod 58 along the horizontal direction.

[0062] It can be understood that since the slider 59 is arranged on the loading platform 2, and the end of the slider 59 away from the loading platform 2 extends into the guide groove and is slidably mounted on the slide rod 58 in the horizontal direction, the U-shaped plate 57 can be stably slidably arranged on the loading platform 2 by utilizing the cooperation of the slide rod 58 and the slider 59, thereby ensuring the linkage of the first piston assembly 55 and the second piston assembly 56.

[0063] It should be noted that the arrangement of the slide bar 58 and the slider 59 can accurately guide the U-shaped plate 57, ensure the accuracy of the movement direction, avoid deviation or shaking, improve the stability and reliability of the movement of the entire discharge device, and make the discharge device more accurate and efficient when the discharge rod 4 is extended, etc., ensuring the normal operation and safety of the discharge device.

[0064] like Figure 1 and Figure 2 As shown, in some embodiments, the base 1 is provided with a resisting column 11, and an end of the resisting column 11 away from the base 1 and an end of the resisting plate 53 away from the second sliding cavity 52 are arranged opposite to each other. When the loading platform 2 descends, the resisting plate 53 abuts against the resisting column 11; when the loading platform 2 rises, the resisting plate 53 is away from the resisting column 11.

[0065] It can be understood that when the loading platform 2 descends, the contact plate 53 and the contact column 11 abut against each other, thereby achieving the exhaust and contraction of the second linkage chamber and the first linkage chamber, and then achieving the storage of the charging rod; when the loading platform 2 rises, the contact plate 53 moves away from the contact column 11, thereby achieving the inflation and expansion of the second linkage chamber and the first linkage chamber, and then achieving the extension of the charging rod.

[0066] like Figure 1 As shown, in some embodiments, the discharge device further includes: a discharge wire 6 and a winding mechanism 7, and the winding mechanism 7 includes: a winding roller 71 and a second driving mechanism 72. The winding roller 71 is rotatably arranged on the base 1, and one end of the discharge wire 6 is connected to the discharge rod 4, and the end of the discharge wire 6 away from the discharge rod 4 is wound around the winding roller 71 and then grounded; the second driving mechanism 72 is transmission-connected to the winding roller 71, and the second driving mechanism 72 is used to drive the winding roller 71 to rotate, so as to wind the discharge wire 6 when the loading platform 2 descends, or release the discharge wire 6 when the loading platform 2 rises.

[0067] It can be understood that, since one end of the discharge wire 6 is connected to the discharge rod 4 and the end of the discharge wire 6 away from the discharge rod 4 is wound around the winding roller 71 and then grounded, the discharge rod 4 can be grounded using the discharge wire 6, thereby ensuring stable discharge to the target sample.

[0068] When the loading platform 2 descends, the second driving mechanism 72 drives the winding roller 71 to rotate forwardly so that the winding roller 71 winds up the discharge wire 6; when the loading platform 2 ascends, the second driving mechanism 72 drives the winding roller 71 to rotate reversely so that the winding roller 71 releases the discharge wire 6. Thus, by using the cooperation of the winding mechanism 7, the winding and stacking of the discharge wire 6 can be avoided, thereby reducing the wear of the discharge wire 6 and extending the service life of the discharge wire 6.

[0069] It should be noted that the release of the discharge wire 6 can be accurately controlled by rotating the winding roller 71, which improves the accuracy and stability of the discharge device operation. At the same time, it can also effectively protect the discharge wire 6, extend its service life, reduce equipment failures and maintenance costs caused by wire problems, and improve the working efficiency and reliability of the entire discharge device. The discharge wire 6 can be rewound to the outside by controlling the winding roller 71 to rotate in the opposite direction through the second drive mechanism 72, so as to facilitate later reuse.

[0070] The discharge wire 6 is used for grounding the discharge rod 4. The specific type of the discharge wire 6 can be set according to actual needs and is not limited thereto.

[0071] The winding roller 71 is used to wind or release the discharge wire 6. The specific type of the winding roller 71 can be set according to actual needs and is not limited to this. For example, the winding roller 71 is a roller body structure, and a plurality of winding grooves are arranged on the winding roller 71. The axial direction of the winding roller 71 is perpendicular to the extension and retraction direction of the discharge rod 4.

[0072] The second driving mechanism 72 is used to drive the winding roller 71 to rotate. The specific type of the second driving mechanism 72 can be set according to actual needs and is not limited to this. For example, the second driving mechanism 72 can be a cooperative driving mechanism of a driving motor and a reducer.

[0073] like Figure 3 As shown, in some embodiments, the winding mechanism 7 also includes: a reciprocating screw 73, a sleeve 74 and an ear plate 75. The reciprocating screw 73 is rotatably set on the base 1, and the reciprocating screw 73 is transmission-connected to the second driving mechanism 72. The second driving mechanism 72 is used to drive the reciprocating screw 73 to rotate. The sleeve 74 is slidably set on the base 1 along the axial direction of the winding roller 71, and the sleeve 74 is threadedly sleeved on the reciprocating screw 73. The ear plate 75 is set on the sleeve 74, and the ear plate 75 is provided with a guide hole. The end of the discharge wire 6 away from the discharge rod 4 passes through the guide hole and then winds around the winding roller 71.

[0074] It can be understood that when the loading platform 2 descends, the second driving mechanism 72 drives the winding roller 71 to rotate forward so that the winding roller 71 winds up the discharge wire 6. At the same time, the second driving mechanism 72 also drives the reciprocating screw 73 to rotate, thereby driving the sleeve 74 and the ear plate 75 to move back and forth, thereby guiding the discharge wire 6 to be evenly wound on the winding roller 71; when the loading platform 2 rises, the second driving mechanism 72 drives the winding roller 71 to rotate in the opposite direction so that the winding roller 71 releases the discharge wire 6. At the same time, the second driving mechanism 72 also drives the reciprocating screw 73 to rotate, thereby driving the sleeve 74 and the ear plate 75 to move back and forth, thereby guiding the discharge wire 6 to be evenly released from the winding roller 71.

[0075] It should be noted that, by evenly winding the discharge wire 6, it is possible to avoid stacking and uneven winding of the discharge wire 6, effectively protecting the discharge wire 6 and extending its service life. At the same time, the evenly wound discharge wire 6 is also smoother in the subsequent release process, and will not have problems such as knotting and jamming, thereby ensuring the continuity and stability of the discharge operation, improving the working efficiency of the discharge device, and reducing equipment failures and maintenance costs caused by wire winding problems.

[0076] The reciprocating screw 73 is used to rotate under the drive of the second driving mechanism 72 to drive the sleeve 74 and the ear plate 75 to reciprocate. The specific type of the reciprocating screw 73 can be set according to actual needs and is not limited to this. The reciprocating screw and the second driving mechanism 72 can be driven by a belt. Specifically, the reciprocating screw and the winding roller 71 are both provided with pulleys, and the two pulleys are connected by a belt drive.

[0077] The sleeve 74 is used to reciprocate under the drive of the reciprocating screw 73. The specific type of the sleeve 74 can be set according to actual needs and is not limited to this.

[0078] The ear plate 75 is used to move synchronously with the sleeve 74. The specific type of the ear plate 75 can be set according to actual needs and is not limited to this.

[0079] like Figure 1 As shown, in some embodiments, the discharge device further includes: a walking mechanism 8 and a current detection module 9, the walking mechanism 8 is arranged at the bottom of the base 1, and the walking mechanism 8 is used for the walking of the base 1, the detection end of the current detection module 9 is arranged on the discharge wire 6, and the signal output end of the current detection module 9 is connected to the signal input end of the walking mechanism 8. When the discharge rod 4 approaches the target sample and the current of the discharge wire 6 reaches the preset current condition, the walking mechanism 8 stops moving.

[0080] It can be understood that, by utilizing the arrangement of the walking mechanism 8, the walking of the discharge device as a whole can be realized, and by arranging the current detection module 9, the discharge state on the discharge wire 6 can be obtained in real time. Thus, when the discharge rod 4 approaches the target sample and the current of the discharge wire 6 reaches the preset current condition, the walking mechanism 8 stops moving, thereby ensuring that the discharge rod 4 and the target sample can accurately reach the preset distance, thereby realizing a high-efficiency and high-quality discharge operation.

[0081] It should be noted that the walking mechanism 8 is used for the base 1 to walk. The specific type of the walking mechanism 8 can be set according to actual needs and is not limited to this. For example, the walking mechanism 8 includes: a plurality of walking wheels arranged at the bottom of the base 1 and a motor and a reducer for driving the walking wheels.

[0082] The current detection module 9 is used to detect the current of the discharge wire 6. The specific type of the current detection module 9 can be set according to actual needs and is not limited to this. For example, the current detection module 9 can be a current transformer.

[0083] Among them, the preset current condition can be a preset current value, current fluctuation value, etc. By setting the preset current condition, damage to the target test product due to excessive discharge can be avoided, and at the same time, operators can be prevented from being electrocuted due to accidentally approaching high voltage areas.

[0084] This embodiment also provides a discharge method, comprising the following steps:

[0085] S1, first move the device to approach the target sample position through the walking mechanism 8;

[0086] S2, by controlling the first driving mechanism 3 to extend the discharge rod 4 to the outside, so as to further adjust the position of the discharge rod 4 and the target sample, and at the same time, by synchronously releasing the discharge wire 6 through the second driving mechanism 72, so that the discharge wire 6 is smoother during the release process;

[0087] S3, then the current detection module 9 arranged outside the discharge wire 6 detects the current state, when the current of the discharge wire 6 reaches the preset current condition, the walking mechanism 8 stops, when the current of the discharge wire 6 does not reach the preset current condition, the walking mechanism 8 continues to move and makes the discharge rod 4 gradually approach the target sample;

[0088] S4, after the discharge operation is completed, the first driving mechanism 3 drives the loading platform 2 to descend, and the discharge rod 4 is automatically stored in the loading platform 2, and at the same time, the second driving mechanism 72 reverses and drives the winding roller 71 to rotate in the opposite direction to wind up the discharge wire 6;

[0089] S5 . During the winding process of the discharge wire 6 , the second driving mechanism 72 controls the ear plate 75 to move back and forth synchronously, so that the discharge wire 6 is evenly wound on the winding roller 71 .
