Description

Technical Field

[0001] The present application belongs to the technical field of ship engineering material testing, and in particular relates to an electrode testing device and a testing method. Background Art

[0002] In the field of marine engineering, optoelectronic slip rings are key components for transmitting power and signals between rotating and stationary equipment. Their performance directly impacts the stability and reliability of the entire system. Electrodes, the core components responsible for signal transmission within optoelectronic slip rings, can experience changes in contact resistance over time due to continuous friction with other components, affecting signal transmission quality and even causing equipment failure.

[0003] However, existing technologies for testing electrodes in optoelectronic slip rings focus primarily on static performance testing, such as the conductivity of the electrode material and initial contact resistance measurement. These methods lack effective means of detecting changes in contact resistance caused by friction during actual operation. This inability to accurately assess the stability and reliability of electrode contact resistance under long-term friction leads to frequent failures caused by changes in electrode contact resistance in practical applications. This not only increases equipment maintenance costs but can also lead to serious consequences such as loss of marine monitoring data and interruption of offshore operations. Summary of the Invention

DETAILED DESCRIPTION

[0045] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0046] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0047] It should be understood that the terms "length", "width", "up", "down", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0048] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0049] It is important to note that with the adjustment of the global energy demand structure, the focus of oil extraction has gradually shifted from land to sea, and the independent research and development of marine engineering equipment has become a key part of my country's energy strategy. The relevant documents clearly list core marine engineering equipment such as the single point mooring system (SPM) as key breakthrough directions. Among them, the optoelectronic slip ring system is the core component of the SPM to achieve rotary transmission of gas, liquid and electrical signals, which directly determines the reliability and transmission efficiency of the equipment. However, due to its sophisticated structure and the need to operate in a marine environment with high salt fog, strong corrosion and severe shaking for a long time, the system faces challenges such as large R&D investment, high technical difficulty and difficult risk control.

[0050] In related technologies, the electrode contact portion of the optoelectronic slip ring system is subjected to intense and complex dynamic friction due to the continuous impact of waves and the high-frequency vibration of the equipment. Under the influence of long-term dynamic friction, the contact resistance of the electrode may change, resulting in unstable electrical signal transmission, such as signal attenuation, distortion, and even interruption, seriously affecting the signal transmission quality of the optoelectronic slip ring system. In high-voltage and high-current operating environments, abnormal fluctuations in contact resistance can also cause local overheating, resulting in arc discharge, which not only accelerates electrode wear and shortens equipment life, but can also cause serious safety accidents such as fire.

[0051] Existing testing methods for optoelectronic slip-ring electrodes suffer from significant drawbacks. Firstly, there is a lack of experimental equipment capable of simulating the dynamic friction conditions found in complex marine environments, making it difficult to replicate the wear process experienced by electrodes in real-world applications. Secondly, existing contact resistance measurement methods are inaccurate, unable to accurately capture the impact of small resistance changes on system performance. This results in a lack of key data support for research on potential arc protection structures such as electric rotation transmission under the combined conditions of high voltage, high current, and strong disturbances, hindering the independent development of optoelectronic slip-ring systems.

[0052] Based on this, the present application improves the relevant electrode testing device and testing method.

[0053] See also Figure 1 , Figure 1 The schematic diagram of the electrode testing device provided in this embodiment is shown. The electrode testing device in this embodiment includes a fixing frame 100 and a conductive clamp 300. The fixing frame 100 has a fixing position for fixing the electrode to be tested 200. The conductive clamp 300 is arranged on one side of the fixing position and is provided with a first clamping opening for clamping and adapting to the electrode to be tested 200. The clamping wall of the first clamping opening is configured to be slidably connected to the electrode to be tested 200 along the length direction of the electrode to be tested 200. The conductive clamp 300 is configured to slide back and forth along the length direction of the electrode to be tested 200 to rub the electrode to be tested 200.

[0054] It should be explained that the fixing frame 100 is a structural component used to provide support and positioning functions. Its main function is to provide a stable installation position for other components (such as the electrode to be tested 200) to ensure that they maintain a relatively static and accurate positional relationship under a specific working environment. The fixing position is a specially designed area on the fixing frame 100. Its shape, size and characteristics are customized according to the specific requirements of the object to be tested (such as the electrode to be tested 200) in order to achieve accurate fixation and constraint of the object to be tested. The conductive clamp 300 is a clamping tool with conductive properties. It can not only clamp the object to be tested (such as the electrode to be tested 200), but also realize the transmission of current during the contact process. The first clamping port is the part on the conductive clamp 300 used for direct contact and clamping with the object to be tested. Its shape and size are adapted to the electrode to be tested 200 to ensure good clamping effect and electrical contact performance. The electrode to be tested 200 refers to the electrode that needs to be tested for performance testing. It is usually the core object of the entire test system. Its performance indicators (such as contact resistance) are evaluated by performing various test operations (such as simulated friction) on it.

[0055] It can be understood that, in the embodiment of the present application, on the one hand, the friction process of the photoelectric slip ring on the electrode in the marine environment is simulated by rubbing the electrode with the clamp, which can more realistically reflect the change of the contact resistance of the electrode under actual friction conditions, thereby effectively improving the accuracy and reliability of the detection data; on the other hand, the fixed position of the fixing frame 100 can firmly clamp the electrode 200 to be tested, avoiding the shaking of the electrode during the test to affect the detection accuracy. At the same time, it is only necessary to overcome the friction between the electrode 200 to be tested and the clamp, which is beneficial to reduce the cost of the device by reducing the driving force.

[0056] Specifically, the mass of the electrode 200 to be tested is usually large. If the electrode 200 to be tested is pushed back and forth, a large driving force is required, which also increases the cost of the driving module. Therefore, in the embodiment of the present application, the driving fixture movement is selected to reduce the cost of the driving module.

[0057] In some embodiments, the first clamping opening of the conductive clamp 300 is a crocodile mouth-like structure.

[0058] In some embodiments of this application, please continue to refer to Figure 1 The electrode testing device of this embodiment also includes a linear module 400, which is arranged on the fixed frame 100 and is arranged on the same side of the fixed position as the conductive clamp 300; wherein, the linear module 400 includes a driving member 450, and the driving member 450 is used to reciprocate along the length direction of the electrode 200 to be tested. The conductive clamp 300 is fixed on the driving member 450 and moves with the driving member 450.

[0059] It is understandable that the linear module 400 can drive the conductive fixture 300 to move through the driving member 450, thereby rubbing the surface of the electrode to be tested 200, thereby simulating the impact of the shaking of the oil and gas platform under the action of waves on the electrical contact device.

[0060] In some embodiments of this application, please continue to refer to Figure 1 The linear module 400 of this embodiment includes a rotary motor 410 and a screw 420; the rotary motor 410 is arranged on the fixed frame 100; the screw 420 is connected to the output shaft of the rotary motor 410 and rotates coaxially with the output shaft of the rotary motor 410; wherein the screw 420 is inserted into the driving member 450 and is threadedly connected to the driving member 450.

[0061] It should be noted that the linear module 400 is a mechanical device that converts rotary motion into linear motion. It typically consists of a driver 450, a transmission mechanism, and a guide mechanism. In this device, it provides linear motion power and guidance for the conductive fixture 300. The driver 450 is the core power component of the linear module 400. It receives external control signals and converts energy such as electrical energy and hydraulic energy into mechanical energy, thereby driving the module to perform reciprocating linear motion along a specific direction (e.g., the length of the electrode 200 under test in this device).

[0062] It can be understood that, for example, when the output shaft of the rotating motor 410 rotates forward, the output shaft drives the screw 420 to rotate. Since the screw 420 is threadedly connected to the driving member 450, the driving member 450 moves away from the rotating motor 410. When the output shaft of the rotating motor 410 is reversed, the output shaft drives the screw 420 to rotate, and the driving member 450 moves closer to the rotating motor 410, thereby realizing the reciprocating motion of the driving member 450, and thus realizing the reciprocating motion of the conductive clamp 300.

[0063] Specifically, linear module 400 can more accurately control parameters such as speed, stroke, and frequency. For example, by precisely controlling the speed of driver 450, the friction speed of an optoelectronic slip ring against an electrode under different sea conditions can be simulated, enabling a more comprehensive study of electrode performance changes under various practical operating conditions.

[0064] In some embodiments of this application, please continue to refer to Figure 1 The electrode testing device of this embodiment further includes a guide member 430, which is arranged on at least one side of the screw 420; a through hole is provided on the driving member 450, and the guide member 430 is passed through the through hole and forms a clearance fit with the hole wall of the through hole.

[0065] It should be explained that the guide member 430 is a component that serves a guiding and positioning function. It ensures that the driving member 450 moves linearly along a specific direction, enhancing the stability and accuracy of the device's movement. The first through-hole is a hole formed in the driving member 450, which allows the guide member 430 to pass through, thereby achieving a fit between the guide member 430 and the driving member 450. A clearance fit refers to a certain gap between the guide member 430 and the wall of the first through-hole. This ensures that the guide member 430 can slide freely relative to the first through-hole, while also constraining and guiding the movement of the driving member 450.

[0066] It is understandable that when the driving member 450 makes a reciprocating linear motion along the screw 420, the guide member 430 can prevent the driving member 450 from deflecting or shaking. The clearance fit design allows the guide member 430 to provide accurate guidance for the driving member 450 without generating excessive friction to hinder the movement of the driving member 450. The gap between the guide member 430 and the wall of the first through hole can be precisely adjusted according to actual needs to meet different test accuracy requirements. The presence of the guide member 430 shares part of the force on the screw 420, reducing the wear of the screw 420 during movement.

[0067] In some embodiments of this application, please continue to refer to Figure 1In this embodiment, the number of guide members 430 is at least two, and at least two guide members 430 are provided on both sides of the screw 420. In this way, the multiple guide members 430 can constrain and guide the driving member 450 from different positions, further enhancing the stability and accuracy of the movement of the device.

[0068] In some embodiments of this application, please continue to refer to Figure 1 In this embodiment, at least one limiting block 440 is fixed on the guide member 430 , and the limiting block 440 is used to form a limiting block in the moving direction of the driving member 450 .

[0069] It will be appreciated that the stopper 440 is a component fixed to the guide member 430. Its function is to limit the range of motion of the driver 450 as it moves along the guide member 430. When the driver 450 moves to a specific position, the stopper 440 blocks the driver 450, preventing it from moving further. This prevents the driver 450 from exceeding the predetermined range of motion, thereby ensuring the safety and proper operation of the device.

[0070] In some embodiments, the reciprocating distance of the conductive clamp 300 can be adjusted by adjusting the position of the limit block 440 or adjusting the speed of the rotating motor 410, which is conducive to better adjusting the simulation effect.

[0071] In some embodiments, the electrode testing device further includes a control power supply for driving the rotary motor 410. Specifically, the control power supply can adjust the rotation speed of the rotary motor 410 to adjust the reciprocating speed of the conductive fixture 300, thereby simulating waves of different intensities.

[0072] In some embodiments of this application, please continue to refer to Figure 1 In this embodiment, the number of the limiting blocks 440 is at least two, and the at least two limiting blocks 440 are respectively arranged on both sides of the driving member 450 to limit the driving member 450 between the at least two limiting blocks 440.

[0073] It can be understood that the two limit blocks 440 accurately limit the movement range of the driving member 450, ensuring that it moves within a predetermined trajectory and distance, further enhancing the control over the movement of the driving member 450.

[0074] In some embodiments of this application, please continue to refer to Figure 1 The electrode testing device of this embodiment further includes an insulating member 500 , which is connected to the driving member 450 , and the conductive clamp 300 is fixed on the insulating member 500 .

[0075] It's important to explain that the insulating member 500 is made of an insulating material and provides electrical isolation within the electrode testing device. The insulating member 500 is connected to the driver 450 and supports the conductive fixture 300. This ensures that the current generated by the conductive fixture 300 during operation is not conducted to the driver 450 or other non-conductive components, preventing short circuits and interference caused by current leakage, thereby ensuring a safe and accurate testing process.

[0076] It is understood that the insulating member 500 effectively blocks the current conduction path between the conductive fixture 300 and the driver 450. During the electrode test, if the current from the conductive fixture 300 is transmitted to the driver 450, it may interfere with the resistance measuring instrument's accurate measurement of the electrode contact resistance, resulting in data errors. The presence of the insulating member 500 ensures that the current in the measurement circuit only passes through the loop formed by the electrode 200 to be tested and the conductive fixture 300. This ensures that the data obtained by the resistance measuring instrument truly reflects the performance of the electrode under simulated friction conditions, improving the reliability and accuracy of the test results.

[0077] In some embodiments of this application, please continue to refer to Figure 1 In this embodiment, a second clamping opening is provided on the insulating member 500 , and the second clamping opening is used to clamp the conductive clamp 300 .

[0078] It is understood that the second clamping opening is a specific structure formed on the insulating member 500, and its function is to firmly clamp the conductive clamp 300. In this way, the conductive clamp 300 is tightly connected to the insulating member 500, thereby ensuring the stability and reliability of the conductive clamp 300 when following the movement of the driving member 450.

[0079] In some embodiments of this application, please refer to Figure 2 , Figure 2 The structure of the electrode testing device provided in this embodiment is shown as a schematic diagram. The fixing frame 100 of this embodiment includes a base 110, a first fixing member 120, a second fixing member 130, a first fixing plate 140, and a second fixing plate 150. The linear module 400 is disposed on the base 110; the first fixing member 120 is disposed at one end of the base 110 and is arranged perpendicular to the base 110; the second fixing member 130 is disposed at the other end of the base 110 and is arranged perpendicular to the base 110, and the second fixing member 130 and the first fixing member 120 are arranged opposite each other; the first fixing plate 140 is disposed at the end of the first fixing member 120 away from the base 110 and is arranged toward the second fixing member 130; the second fixing plate 150 is disposed at the end of the second fixing member 130 away from the base 110 and is arranged toward the first fixing member 120. The first fixing member 120 and the second fixing member 130 are arranged opposite each other and are used to jointly fix the electrode 200 to be tested.

[0080] It's important to explain that base 110 serves as the foundational support component of the entire mounting frame 100, providing a mounting platform for the linear module 400 and other components, ensuring device stability. First and second fixing members 120, 130 are vertically mounted on opposite ends of base 110. Their primary function is to secure first and second fixing plates 140, 150. These plates, together, secure the electrodes 200 under test, ensuring they remain fixed in place during testing and prevent movement or shaking.

[0081] It is understood that the first fixing plate 140 and the second fixing plate 150 strengthen the fixing stability of the electrode 200 to be tested, which can effectively prevent the electrode from being displaced or shaken due to the friction of the conductive clamp 300 during the test process. This ensures the relative position between the electrode and the conductive clamp 300 is stable, thereby improving the accuracy of the resistance measurement and the reliability of the test results.

[0082] In some embodiments, the first fixing plate 140 and the first fixing member 120 are detachably connected, and the second fixing plate 150 and the second fixing member 130 are detachably connected. After the specifications of the electrode to be tested 200 change, the installation adaptation of the electrode to be tested 200 can be ensured by replacing the first fixing plate 140 and the second fixing plate 150.

[0083] In some embodiments, the insulation 500 is made of reinforced nylon material.

[0084] In some embodiments, the first fixing plate 140 and the second fixing plate 150 are made of reinforced nylon material.

[0085] It can be understood that the reinforced nylon material has high lightness and rigidity, ensuring that the clamping parts resist deformation during high-speed reciprocating motion, avoiding the decrease in clamping force due to long-term stress; and the reinforced nylon material has excellent wear resistance and fatigue resistance, avoiding cracks or other defects under long-term reciprocating motion; compared with other materials, the reinforced nylon material has a lower density, which can reduce the weight of the device and increase the portability of the device; at the same time, the vibration attenuation coefficient of the reinforced nylon material is 6-8 times higher than that of metal, which can effectively reduce the noise when the device is in use.

[0086] Furthermore, in order to better implement the electrode testing device in any of the above embodiments, based on the above electrode testing device, please refer to Figure 3 , Figure 3 The following is a schematic diagram showing the steps of the electrode testing method provided in this embodiment; the present application also provides an electrode testing method, which includes:

[0087] S100: rubbing the electrode 200 to be tested using the electrode testing device as described above;

[0088] Specifically, the electrode 200 to be tested is first fixed between the first fixed plate 140 and the second fixed plate 150, the conductive clamp 300 is connected to the driving member 450 via the insulating member 500, and the driving member 450 is adjusted to the initial position. The driving member 450 then drives the insulating member 500 and the conductive clamp 300 to perform reciprocating linear motion along the screw 420. The clamping wall of the first clamping port of the conductive clamp 300 generates friction with the electrode surface, simulating the friction of the photoelectric slip ring on the electrode in the marine environment. During this process, the guide member 430 constrains the movement of the driving member 450, and the limit block 440 limits the range of motion of the driving member 450 to ensure that the friction process is stable and accurate.

[0089] S200: Obtaining the contact resistance value between the electrode to be tested 200 and the conductive fixture 300 after friction.

[0090] Specifically, the resistance measuring instrument can measure the contact resistance between the conductive fixture 300 and the electrode to be measured 200 in real time during the friction process, and can also measure the contact resistance between the two after the friction process is completed.

[0091] In some embodiments of this application, please refer to Figure 4 , Figure 4 FIG. 2 is a schematic diagram showing the steps of the electrode testing method provided in this embodiment. Step S200 of this embodiment includes:

[0092] S210: Acquire a first resistance value of the electrode to be measured 200, acquire a second resistance value of the conductive clamp 300, and acquire a third resistance value when the electrode to be measured 200 and the conductive clamp 300 are in a connected state;

[0093] Specifically, a resistance measuring instrument can be used to measure the resistance of the electrode 200 to obtain a first resistance value. The resistance of the conductive fixture 300 can be measured to obtain a second resistance value. After the electrode 200 is rubbed with the electrode testing device, the electrode 200 and the conductive fixture 300 remain connected, and the resistance measuring instrument is used again to measure the total resistance of the combination to obtain a third resistance value.

[0094] S220 : Obtain a contact resistance value based on the first resistance value and the second resistance value minus the third resistance value.

[0095] Specifically, when two resistors are connected in series, the total resistance is equal to the sum of the individual resistances. Therefore, when the electrode to be measured 200 is connected to the conductive fixture 300, the third resistance value (total resistance) is equal to the sum of the first resistance value (the resistance of the electrode to be measured 200), the second resistance value (the resistance of the conductive fixture 300) and the contact resistance. By subtracting the third resistance value from the sum of the first resistance value and the second resistance value, the contact resistance between the electrode to be measured 200 and the conductive fixture 300 can be obtained.

[0096] In some embodiments of the present application, the specific operation process of the electrode testing device is as follows:

[0097] First, install the electrode 200 to be tested on the fixed position of the fixing frame 100 and fix it with the help of the conductive clamp 300. Then adjust the limit block 440 of the linear module 400 to the preset position, start the linear module 400 by controlling the power supply, and adjust the moving speed of the conductive clamp 300. After confirming that the number of reciprocating motions is sufficient, cut off the control power supply.

[0098] Specifically, first place the electrode 200 to be tested into the conductive fixture 300, then secure it to the insulating member 500 and adjust its height. Then, secure the electrode 200 to the first and second fixing plates 140 and 150 with screws to ensure a secure installation. At this point, observe the position of the limit block 440 fixed to the linear module 400 and adjust the screws of the limit block 440 to adjust the distance of each reciprocating motion as needed. Then, connect the control power supply and start the electrode testing device.

[0099] Specifically, the position of the limit block 440 is determined by the reciprocating distance required by the conductive clamp 300, and the reciprocating speed is determined by the number of reciprocating times required by the conductive clamp 300 and the experimental time, that is, the reciprocating speed is the experimental time divided by the number of reciprocating times.

[0100] In some embodiments, the minimum reciprocating distance is 4 cm, the maximum reciprocating distance is 14 cm, the minimum reciprocating speed is 0 cm / s, and the maximum reciprocating speed is 2 cm / s.

[0101] In some embodiments of this application, please refer to Figure 5 , Figure 5 The following diagram shows the steps of the electrode testing method in this embodiment. The specific electrode testing method is as follows:

[0102] The contact resistance between the electrode 200 to be tested and the conductive fixture 300 is obtained by measuring the resistance of the electrode 200 to be tested, the resistance of the conductive fixture 300, and the resistance of the electrode 200 to be tested and the conductive fixture 300 in contact. Figures 6 to 8As shown, the objects to be tested are the electrode 200 to be tested and the conductive fixture 300, the cone represents the connection with the test leads of the loop resistance tester, the cones at both ends represent the connection with the red test lead and the blue test lead respectively, the large cone represents the large test lead, and the small cone represents the small test lead. Figure 6 、 Figure 7 、 Figure 8 Schematic diagrams respectively represent the wiring method for measuring the resistance of the electrode 200 to be measured, the resistance of the fixture, and the contact resistance between the electrode 200 to be measured and the bottom of the fixture.

[0103] Specifically, the processed electrode 200 to be tested is fixed on the conductive clamp 300, and the resistance of the electrode 200 to be tested is measured by a loop resistance meter. Then, the wiring method is changed to measure the resistance of the clamp itself. Then, one end of the measuring end is connected to the electrode to be tested 200 and the other end is connected to the bottom of the clamp to measure the contact resistance between the electrode to be tested 200 and the clamp. After calculation, the resistance of the electrode to be tested 200 and the clamp minus the resistance of the clamp minus the resistance of the electrode to be tested 200 is the required contact resistance.

[0104] It can be understood that by controlling the position of the test end, multiple sets of measurements were performed, and by controlling the distance between the test leads at both ends of the loop resistance meter, multiple sets of tests were performed during each measurement, and relatively more results were obtained. The relationship between the measurement distance and the contact resistance, and the relationship between the contact resistance and the number of friction times of the electrode to be tested 200 were explored.
