Description

Technical Field

[0001] This disclosure relates to the field of discharge technology, and more particularly to a discharge device. Background Technology

[0002] Currently, when discharging the test specimen for high capacitance withstand voltage test, the test power supply must be disconnected after the high voltage test is completed. The charge on the specimen is used to self-discharge to the ground through the voltage multiplier and the specimen itself. When the voltage drops to about 5-15kV, the operator holds a discharge rod and gradually approaches the specimen to perform ionization discharge. As the voltage decreases, the discharge rod gradually approaches and the tip of the discharge rod can touch the specimen so that the specimen is directly grounded and discharged.

[0003] However, when workers use handheld discharge rods to perform ionization discharge, their control over the discharge position is inaccurate, which not only affects the discharge efficiency and quality but also poses a risk of electric shock to the workers. Summary of the Invention

[0016] The technical solution provided in this disclosure may include the following beneficial effects:

[0017] When the first drive mechanism raises the loading platform, the linkage mechanism moves away from the base and drives the discharge rod to move horizontally, causing the discharge end of the rod to move out of the loading platform. This allows the discharge rod to discharge the target sample. Simultaneously, the first drive mechanism also allows for position control of the discharge rod. Furthermore, when the first drive mechanism lowers the loading platform, the linkage mechanism abuts against the base and drives the discharge rod to move horizontally, causing the discharge end to move into the loading platform, thus retracting the discharge rod. Therefore, through the cooperation of the first drive mechanism and the linkage mechanism, the extension and retraction of the discharge rod can be achieved, while the discharge position can be accurately adjusted, effectively improving the discharge efficiency and quality of the discharge rod and avoiding the risk of electric shock associated with manual operation.

[0032] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0033] like Figure 1 As shown in the figure, this 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 mounted on the base 1 in a 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 mounted inside the loading platform 2 in a horizontal direction and is grounded. The discharge rod 4 is used for discharging the target sample. The linkage mechanism 5 is disposed 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 horizontally, 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 horizontally, so that the discharge end of the discharge rod 4 moves out of the loading platform 2.

[0034] Understandably, when the first drive 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 horizontally, so that the discharge end of the discharge rod 4 moves out of the loading platform 2, thereby using the discharge rod 4 to discharge the target sample. At the same time, the position of the discharge rod 4 can also be adjusted by the drive of the first drive mechanism 3. Moreover, when the first drive mechanism 3 drives the loading platform 2 to fall, the linkage mechanism 5 and the base 1 abut against each other and drive the discharge rod 4 to move horizontally, so that the discharge end of the discharge rod 4 moves into the loading platform 2, thereby realizing the 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 retracted, 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 support components such as the loading platform 2 and the first drive mechanism 3. The specific type of the base 1 can be set according to actual needs and there are no restrictions on it. For example, the base 1 can be a nearly rectangular seat structure.

[0037] The loading platform 2 is used to support components such as the discharge rod 4. The specific type of the loading platform 2 can be set according to actual needs and is not limited thereto. For example, the loading platform 2 can be a nearly rectangular pedestal structure.

[0038] The first drive mechanism 3 is used to drive the loading platform 2 to lift. The specific type of the first drive mechanism 3 can be set according to actual needs and is not limited thereto. For example, the first drive mechanism 3 can be multiple electric push rods, multiple hydraulic cylinders, or multiple pneumatic cylinders.

[0039] The discharge rod 4 is used for ionization discharge and direct discharge of the target sample. The specific type of discharge rod 4 can be set according to actual needs and is not limited thereto. Specifically, after the discharge rod 4 is grounded, the discharge end of the discharge rod 4 is close to the target sample for ionization discharge, and the discharge end of the discharge rod 4 is in contact with 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 and the base 1 abut against each other and drive the discharge rod 4 to move horizontally, so that the discharge end of the discharge rod 4 moves into the loading platform 2. This avoids the discharge rod 4 being constantly exposed, solving the problem that the discharge rod 4 is easily damaged by external physical impacts and friction during movement and storage, affecting its normal discharge function and service life. It protects the discharge rod 4, extends its service life, and improves 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 horizontally, so that the discharge end of the discharge rod 4 moves out of the loading platform 2. This eliminates the need for an additional complex control system and simplifies the operation process of the discharge rod 4.

[0041] The specific type of linkage mechanism 5 can be set according to actual needs, and there are no restrictions on it.

[0042] like Figure 2As shown, in some embodiments, the linkage mechanism 5 includes: a first sliding cavity 51, a second sliding cavity 52, an abutment plate 53, and at least one return spring 54. The first sliding cavity 51 is horizontally disposed within the loading platform 2, and the end of the discharge rod 4 away from its discharge end is horizontally slidably disposed within the first sliding cavity 51, forming a first linkage cavity between the rod and the bottom of the first sliding cavity 51. The second sliding cavity 52 is vertically disposed within the loading platform 2, and one end of the abutment plate 53 is opposite to the base 1. The end of the abutment plate 53 away from the base 1 is vertically slidably disposed within the second sliding cavity 52, forming a second linkage cavity between the abutment plate 53 and the bottom of the second sliding cavity 52. ​​The return spring 54 is disposed within the second linkage cavity. The first and second linkage cavities contract and expand synchronously. When the loading platform 2 descends, the abutment plate 53 abuts against the base 1, causing the second linkage cavity to contract. When the loading platform 2 rises, the abutment plate 53 moves away from the base 1, causing the second linkage cavity to expand.

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

[0044] Since the second sliding cavity 52 is arranged vertically in the loading platform 2, and one end of the abutment plate 53 is arranged opposite to the base 1, the end of the abutment plate 53 away from the base 1 is slidably arranged vertically in the second sliding cavity 52 and forms a second linkage cavity between the bottom of the second sliding cavity 52. ​​This allows the abutment plate 53 to slide vertically when it moves away from the base 1, filling the second linkage cavity with gas. Also, when the abutment plate 53 abuts against the base 1, the end of the abutment plate 53 away from the base 1 can slide vertically and discharge gas from the second linkage cavity.

[0045] Because the first and second linkage cavities contract and expand synchronously, when the loading platform 2 descends, the contact plate 53 abuts against the base 1 and causes the second linkage cavity to discharge gas and contract, thereby causing the first linkage cavity to discharge gas and contract, thus realizing 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 cavity to be filled with gas and expand, thereby causing the first linkage cavity to be filled with gas and expand, thus 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 within 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 horizontally within the loading platform 2, and the end of the first sliding cavity 51 away from the first linkage cavity extends through the loading platform 2. The discharge rod 4 is slidably arranged within the first sliding cavity 51 from the end of the first sliding cavity away from the first linkage cavity. The end of the discharge rod 4 located near the first linkage cavity of the first sliding cavity can be slidably arranged using a circular plate and 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 abutment plate 53 on the loading platform 2. The specific type of the second sliding cavity 52 can be set according to actual needs and is not limited thereto. For example, the second sliding cavity 52 is arranged vertically in the extrusion box at the bottom of the loading platform 2, and the end of the second sliding cavity 52 away from the second linkage cavity extends through the extrusion box. The connecting plate provided on the abutment plate 53 is slidably arranged in the second sliding cavity 52 from the end of the second sliding cavity away from the second linkage cavity. Among them, the end of the second sliding cavity 52 near the second linkage cavity can be slidably arranged by a piston plate.

[0048] The contact plate 53 is used to cooperate with the base 1 to realize the linkage between the discharge rod 4 and the first drive mechanism 3. The specific type of the contact plate 53 can be set according to actual needs and there is no limitation. For example, the contact plate 53 is a plate structure and 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 abutment plate 53 so that when the abutment plate 53 is away from the base 1, the second linkage cavity can be inflated and expanded, thereby enabling the discharge rod 4 to extend. The specific type of the reset spring 54 can be set according to actual needs and is not limited thereto. For example, the reset spring 54 is a helical spring, and multiple reset springs 54 are evenly distributed between the bottom of the abutment plate 53 and 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 disposed on the loading platform 2 in a horizontal direction, with one end of the U-shaped plate 57 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 connected to the piston end of the second piston assembly 56.

[0051] It is understandable 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 contract 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 contract 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 contraction and expansion using the U-shaped plate 57.

[0052] Thus, when the loading platform 2 descends, the contact plate 53 abuts against the base 1 and causes the second linkage cavity to contract, thereby utilizing the linkage of the first piston assembly 55 and the second piston assembly 56 to realize 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 cavity to expand, thereby utilizing the linkage of the first piston assembly 55 and the second piston assembly 56 to realize the extension of the discharge rod 4.

[0053] It should be noted that the lifting of the loading platform 2 synchronously drives the discharge rod 4 to extend, eliminating the need for an additional complex control system, simplifying the operation process, ensuring high stability and reliability, improving the convenience and safety of the discharge device, and saving energy to a certain extent. After the device is used, the discharge platform descends and resets, and the discharge rod 4 is re-stored in the loading platform 2 to prevent the discharge rod 4 from being bumped during the movement and storage process, thereby improving 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 filled with air and expands, the piston end of the first piston assembly 55 extends out. When the first linkage chamber is released 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 thereto.

[0055] The cylinder end of the second piston assembly 56 is connected to the second linkage chamber. When the second linkage chamber is filled with air and expands, the piston end of the second piston assembly 56 extends out. When the second linkage chamber is released 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 thereto.

[0056] The U-shaped plate 57 is used for 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 extension and retraction directions of the first piston assembly 55 and the second piston assembly 56 are the same.

[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 disposed within the loading platform 2, and the first piston column 552 is horizontally slidably disposed within the first piston chamber 551. One end of the first piston rod 553 is connected to the first piston column 552, and the 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 the end of the U-shaped plate 57 away from the second piston assembly 56. The end of the first piston chamber 551 away from the first piston rod 553 communicates with a first linkage chamber.

[0058] Understandably, when the U-shaped plate 57 moves in the direction closer 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 causing the first piston chamber 551 to vent and contract and the first linkage chamber to vent and expand, thus realizing the extension of the discharge rod 4; when the U-shaped plate 57 moves in the 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 causing the first piston chamber 551 to vent and expand and the first linkage chamber to vent and contract, thus realizing 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 rod 562, and a second piston rod 563. The second piston chamber 561 is horizontally disposed on the loading platform 2, and the second piston rod 562 is horizontally slidably disposed within the second piston chamber 561. One end of the second piston rod 563 is connected to the second piston rod 562, and the end of the second piston rod 563 away from the second piston rod 562 extends out of the second piston chamber 561 and is connected to the end of the U-shaped plate 57 away from the first piston assembly 55. The end of the second piston chamber 561 away from the second piston rod 563 communicates with the second linkage chamber.

[0060] It is understandable that when the second linkage chamber is inflated, it causes the second piston chamber 561 to deflate and contract, thereby causing the second piston rod 562 and the second piston rod 563 to move synchronously, and then causing the U-shaped plate 57 to move in the direction closer to the loading platform 2; when the second linkage chamber deflates and contracts, it causes the second piston chamber 561 to inflate and expand, thereby causing the second piston rod 562 and the second piston rod 563 to move synchronously, and then causing 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 further includes a slide rod 58 and a slider 59. The end of the U-shaped plate 57 away from the first piston assembly 55 is provided with a guide groove, and the slide rod 58 is arranged in the guide groove in a 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 slides horizontally on the slide rod 58.

[0062] It is understandable that since the slider 59 is set on the loading platform 2, and the end of the slider 59 away from the loading platform 2 extends into the guide groove and slides horizontally on the slide rod 58, the U-shaped plate 57 can be stably slidably arranged on the loading platform 2 by means of 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 provides precise guidance for the U-shaped plate 57, ensuring the accuracy of the movement direction and preventing deviation or swaying. This improves the stability and reliability of the entire discharge device's movement. Furthermore, it allows for more precise and efficient operation of the discharge device, such as extending the discharge rod 4, thus guaranteeing 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 an abutment post 11, and the end of the abutment post 11 away from the base 1 and the end of the abutment plate 53 away from the second sliding cavity 52 are arranged opposite each other. When the loading platform 2 descends, the abutment plate 53 and the abutment post 11 abut against each other; when the loading platform 2 rises, the abutment plate 53 moves away from the abutment post 11.

[0065] Understandably, when the loading platform 2 descends, the contact plate 53 and the contact post 11 come into contact, thereby achieving the exhaust and contraction of the second linkage chamber and the first linkage chamber, and thus realizing the storage of the charging rod; when the loading platform 2 rises, the contact plate 53 moves away from the contact post 11, thereby achieving the inflation and expansion of the second linkage chamber and the first linkage chamber, and thus realizing 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. The winding mechanism 7 includes a take-up roller 71 and a second drive mechanism 72. The take-up roller 71 is rotatably mounted on the base 1, and one end of the discharge wire 6 is connected to the discharge rod 4. The end of the discharge wire 6 away from the discharge rod 4 is wound around the take-up roller 71 and grounded. The second drive mechanism 72 is drively connected to the take-up roller 71 and is used to drive the take-up roller 71 to rotate, so as to wind the discharge wire 6 when the loading platform 2 descends, or to release the discharge wire 6 when the loading platform 2 rises.

[0067] It is understandable 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 grounded after being wound around the take-up roller 71, the discharge rod 4 can be grounded by using the discharge wire 6, thereby ensuring stable discharge to the target sample.

[0068] When the loading platform 2 descends, the second drive mechanism 72 drives the take-up roller 71 to rotate in the forward direction, so that the take-up roller 71 winds the discharge wire 6; when the loading platform 2 rises, the second drive mechanism 72 drives the take-up roller 71 to rotate in the reverse direction, so that the take-up roller 71 releases the discharge wire 6. Thus, by utilizing the winding mechanism 7, the entanglement and stacking of the discharge wire 6 can be avoided, thereby reducing the wear of the discharge wire 6 and extending its service life.

[0069] It should be noted that the release of the discharge wire 6 can be precisely controlled by rotating the take-up roller 71, which improves the accuracy and stability of the operation of the discharge device. At the same time, it can also effectively protect the discharge wire 6, extend its service life, reduce equipment failure 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 take-up roller 71 to rotate in the opposite direction through the second drive mechanism 72, which is convenient for 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 there are no restrictions on it.

[0071] The take-up roller 71 is used to wind or release the discharge wire 6. The specific type of the take-up roller 71 can be set according to actual needs and there is no limitation. For example, the take-up roller 71 is a roller body structure and multiple winding grooves are arranged on the take-up roller 71. The axial direction of the take-up roller 71 is perpendicular to the extension and retraction direction of the discharge rod 4.

[0072] The second drive mechanism 72 is used to drive the take-up roller 71 to rotate. The specific type of the second drive mechanism 72 can be set according to actual needs and is not limited thereto. For example, the second drive mechanism 72 can be a drive mechanism that combines a drive motor and a reducer.

[0073] like Figure 3 As shown, in some embodiments, the winding mechanism 7 further includes a reciprocating screw 73, a sleeve 74, and an ear plate 75. The reciprocating screw 73 is rotatably mounted on the base 1 and is connected to the second drive mechanism 72. The second drive mechanism 72 is used to drive the reciprocating screw 73 to rotate. The sleeve 74 is slidably mounted on the base 1 along the axial direction of the take-up roller 71 and is threaded onto the reciprocating screw 73. The ear plate 75 is mounted on the sleeve 74 and has a guide hole. The end of the discharge wire 6 away from the discharge rod 4 passes through the guide hole and is wound around the take-up roller 71.

[0074] Understandably, when the loading platform 2 descends, the second drive mechanism 72 drives the take-up roller 71 to rotate in the forward direction, so that the take-up roller 71 winds the discharge wire 6. At the same time, the second drive 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, thus guiding the discharge wire 6 to be evenly wound on the take-up roller 71. When the loading platform 2 rises, the second drive mechanism 72 drives the take-up roller 71 to rotate in the reverse direction, so that the take-up roller 71 releases the discharge wire 6. At the same time, the second drive 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, thus guiding the discharge wire 6 to be evenly released from the take-up roller 71.

[0075] It should be noted that by uniformly winding the discharge wire 6, the stacking and uneven winding of the discharge wire 6 can be avoided, effectively protecting the discharge wire 6 and extending its service life. At the same time, the uniformly wound discharge wire 6 is smoother in the subsequent release process, without problems such as knotting or jamming, ensuring the continuity and stability of the discharge operation, improving the working efficiency of the discharge device, and reducing equipment failure and maintenance costs caused by wire winding problems.

[0076] The reciprocating screw 73 is rotated under the drive of the second drive 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 thereto. The reciprocating screw and the second drive mechanism 72 can be connected by belt drive. Specifically, both the reciprocating screw and the take-up roller 71 are equipped with pulleys, and the two pulleys are connected by belt drive.

[0077] The sleeve 74 is used to move back and forth under the drive of the reciprocating screw 73. The specific type of sleeve 74 can be set according to actual needs and there is no restriction on it.

[0078] The lug 75 is used to move synchronously with the sleeve 74. The specific type of lug 75 can be set according to actual needs and there is no restriction on it.

[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 disposed at the bottom of the base 1 and is used for the walking of the base 1. The detection end of the current detection module 9 is disposed 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 in the discharge wire 6 reaches a preset current condition, the walking mechanism 8 stops moving.

[0080] Understandably, the arrangement of the walking mechanism 8 enables the entire discharge device to move, and the arrangement of the current detection module 9 allows for real-time monitoring of the discharge state on the discharge wire 6. Therefore, when the discharge rod 4 approaches the target sample and the current in the discharge wire 6 reaches the preset current condition, the walking mechanism 8 stops moving, ensuring that the discharge rod 4 and the target sample can accurately reach the preset distance, thereby achieving high-efficiency and high-quality discharge operations.

[0081] It should be noted that the walking mechanism 8 is used for the movement of the base 1. The specific type of the walking mechanism 8 can be set according to actual needs and there is no limitation. For example, the walking mechanism 8 includes: multiple walking wheels arranged at the bottom of the base 1 and a motor and reducer that drive the walking wheels.

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

[0083] Among them, the preset current conditions can be preset current values, current fluctuation values, etc. By setting the preset current conditions, damage to the target sample due to over-discharge can be avoided, and electric shock can be prevented from the operator accidentally approaching the high voltage area.

[0084] This embodiment also proposes a discharge method, including the following steps:

[0085] S1. First, the device is moved closer to the target sample location by the walking mechanism 8;

[0086] S2. By controlling the first drive mechanism 3, the discharge rod 4 is extended to the outside, which facilitates further adjustment of the position of the discharge rod 4 and the target sample. At the same time, the discharge wire 6 is released synchronously by the second drive mechanism 72, so that the discharge wire 6 is released more smoothly during the release process.

[0087] S3. Then, the current status is detected by the current detection module 9 set on the outside of the discharge wire 6. 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 drive mechanism 3 drives the loading platform 2 to descend, and the discharge rod 4 is automatically stored in the loading platform 2. At the same time, the second drive 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, the second drive mechanism 72 controls the ear plate 75 to move synchronously back and forth so that the discharge wire 6 is evenly wound on the winding roller 71.
