Description

[0002] Safety equipment (such as insulating rods) is an indispensable tool in overhead contact network operation. The quality of its insulation performance is directly related to the safety of operators. Therefore, regular testing of its insulation resistance is an important part of ensuring safe operation. Before each use of the insulating rod, it must be carefully checked for damage, and the effective insulating part must be wiped with a clean and dry rag, and then the insulation resistance of the effective insulating part must be measured in sections with a 2500V megohmmeter (electrode width 2cm, pole spacing 2cm), which must not be less than 100MΩ, or the insulation resistance of the entire effective insulating part must not be less than 10000MΩ.

[0035] The present invention will be further described below in conjunction with the accompanying drawings.

[0036] The present invention provides an insulation resistance detection device, equipment, method and computer-readable storage medium for an insulating rod, which can measure insulating rods of different diameters and the entire effective insulating surface of the insulating rod, thereby improving measurement accuracy.

[0037] like Figure 1-6 As shown, in the first aspect, an embodiment of the present application provides an insulation resistance detection device 1000 for an insulating rod M. The insulation resistance detection device 1000 includes a test assembly 100, and the test assembly 100 includes a plurality of electrode surface contact assemblies 110 and a first part 120 and a second part 130 that are interlocked with each other. The first part 120 has a first recessed portion 121, and the second part 130 has a second recessed portion 131, and the first recessed portion 121 and the second recessed portion 131 form a closed annular cavity. Each electrode surface contact assembly 110 is arranged in the annular cavity at intervals along the circumference of the annular cavity. Among them, the electrode surface contact assembly 110 includes an electrode sheet 111 and a telescopic member 112. One end of the telescopic member 112 along the telescopic direction is connected to the electrode sheet 111, and the other end is connected to the circumferential side wall of the annular cavity. The telescopic direction is the extension direction of the annular cavity.

[0038] According to the insulation resistance detection device 1000 of the embodiment of the present application, when in use, the insulating rod M to be detected is first set in the first recessed portion 121 of the first part 120 or the second recessed portion 131 of the second part 130, and then the first part 120 and the second part 130 are buckled together so that the annular cavity formed by the first recessed portion 121 and the second recessed portion 131 can be sleeved on the insulating rod M. Due to the presence of the telescopic member 112, the electrode sheet 111 can be adaptively adjusted according to the diameter of the insulating rod M to ensure close contact with the effective insulating surface of the insulating rod M to measure the insulation resistance of the insulating rod M. The electrode surface contact assembly 110 is arranged at intervals along the circumference of the annular cavity to ensure coverage of the entire effective insulating surface of the insulating rod M, thereby improving the accuracy and comprehensiveness of the measurement. At the same time, the test assembly 100 of the insulation resistance detection device 1000 can adapt to insulating rods M of different diameters, thereby improving the versatility and flexibility of the measurement.

[0039] like Figure 1 As shown, in some embodiments, the insulation resistance detection device 1000 further includes a first clamping assembly 200, a second clamping assembly 300 and a slide rail 400. At least one of the first clamping assembly 200 and the second clamping assembly 300 is movably connected to the slide rail 400 along the extension direction of the slide rail 400. The first clamping assembly 200 and the second clamping assembly 300 are spaced and arranged opposite to each other. The test assembly 100 is arranged between the first clamping assembly 200 and the second clamping assembly 300, and the extension direction of the slide rail 400 is parallel to the extension direction of the annular cavity.

[0040] At least one of the first clamping assembly 200 and the second clamping assembly 300 is movably connected to the slide rail 400 along the extension direction of the slide rail 400. Specifically, the first clamping assembly 200 may be movably connected to the slide rail 400 along the extension direction of the slide rail 400, or the second clamping assembly 300 may be movably connected to the slide rail 400 along the extension direction of the slide rail 400. Of course, the first clamping assembly 200 and the second clamping assembly 300 may also be movably connected to the slide rail 400 along the extension direction of the slide rail 400 at the same time.

[0041] The slide rail 400 may be a single slide rail 400 , a double slide rail 400 , or multiple slide rails 400 . Exemplarily, a double slide rail 400 may be selected in this embodiment.

[0042] In this embodiment, the slide rail 400 provides a movable track for the first clamping assembly 200 and the second clamping assembly 300, so that they can move relatively along the extension direction of the slide rail 400, which helps to adjust the distance between the first clamping assembly 200 and the second clamping assembly 300 to adapt to different lengths of the insulating rod M. The first clamping assembly 200 and the second clamping assembly 300 are spaced and arranged relatively, and they can clamp the two ends of the insulating rod M to ensure that the insulating rod M remains stable during the measurement process, avoiding measurement errors caused by shaking or movement, and the electrode surface contact assembly 110 is in close contact with the effective insulating surface of the insulating rod M, so the insulation resistance of the insulating rod M can be measured more accurately.

[0043] like Figure 1 As shown, in some embodiments, the insulation resistance detection device 1000 further includes a distance measuring sensor 500 , and the first clamping assembly 200 or one of the first clamping assemblies 200 is connected to the distance measuring sensor 500 .

[0044] The distance measuring sensor 500 can adopt laser distance measurement, ultrasonic distance measurement, infrared distance measurement, etc., or the distance measuring sensor 500 can also be a pull-wire sensor, wherein the pull-wire sensor is connected to one of the first clamping component 200 or the second clamping component 300, and the free end of the pull wire is connected to the second clamping component 300 or the first clamping component 200. When the distance between the first clamping component 200 and the second clamping component 300 changes, the pull-wire sensor can detect the length of the pull wire and then determine the distance between the first clamping component 200 and the second clamping component 300.

[0045] In this embodiment, the ranging sensor 500 can monitor the length of the insulating rod M or the distance between the clamping components in real time, and determine the test plan according to the length of the insulating rod M or the distance between the clamping components, such as setting different detection points according to the different lengths of the insulating rod M, or adjusting the distance between different monitoring points according to the different lengths of the insulating rod M, thereby providing more accurate and reliable measurement results.

[0046] like Figure 1 As shown, in some embodiments, the insulation resistance detection device further includes a moving component 600. The moving component 600 is connected to the test component 100. The moving component 600 drives the test component 100 to move along a first direction, and the first direction is parallel to the extension direction of the annular cavity.

[0047] In this embodiment, the moving component 600 can drive the insulation resistance detection device 1000 to move along the first direction, that is, the length direction of the insulating rod M, so as to monitor the insulation at different positions along the length direction of the insulating rod M, ensure that the different positions of the insulating rod M are tested uniformly, and help to find possible local defects or abnormalities on the insulating rod M, thereby reducing test errors and improving the comprehensiveness of the test. At the same time, the moving component 600 drives the insulation resistance detection device to move, which improves the automation and intelligence of the insulation resistance test device, shortens the test cycle, and improves the test efficiency. At the same time, due to the reduction of manual intervention, the stability and consistency of the test results are also significantly improved.

[0048] like Figure 1 As shown, in some embodiments, the moving assembly 600 includes a driving member 610 and a transmission assembly 620 drivingly connected to the driving member 610. The transmission assembly 620 is connected to the test assembly 100, and the driving member 610 drives the transmission assembly 620 to drive the test assembly 100 to move along the first direction.

[0049] The driving member 610 can be a motor, a hydraulic cylinder or a pneumatic device, and can be a driving motor. The transmission assembly 620 can be a matching gear rack transmission assembly 620, or a synchronous wheel and belt transmission assembly 620.

[0050] When the transmission assembly 620 is a matching gear rack transmission assembly 620, the drive motor and the test assembly 100 are understood, and the drive motor is connected to the gear drive. The drive motor drives the gear to rotate, so that the drive motor can move along the extension direction of the rack. Since the extension direction of the rack is consistent with the length direction of the insulating rod M to be tested, the test assembly 100 can move along the length direction of the insulating rod M to detect different positions of the insulating rod M in the length direction.

[0051] When the transmission assembly 620 is a synchronous wheel and belt transmission assembly 620, the test assembly 100 is connected to the synchronous belt, and the driving motor drives the synchronous wheel to rotate to drive the synchronous belt to move, thereby driving the test assembly 100 on the synchronous belt to move. Since the moving direction of the synchronous belt is consistent with the length direction of the insulating rod M, the test assembly 100 can move along the length direction of the insulating rod M to detect different positions of the insulating rod M in the length direction.

[0052] The specific transmission component 620 to be used needs to be comprehensively considered based on actual needs and scenarios to ensure that the performance and stability of the test device are optimal.

[0053] like Figure 2-6As shown, in some embodiments, the telescopic member 112 includes a base 112a, an electrode mounting seat 112b, a first connecting rod 112c, a second connecting rod 112d and an elastic reset member 112e. The base 112a is connected to the inner wall of the annular cavity. One end of the first connecting rod and one end of the first connecting rod are spaced and rotatably connected to the base 112a along the telescopic direction. The other end of the first connecting rod and the other end of the first connecting rod are spaced and rotatably connected to the two ends of the electrode mounting seat 112b along the length direction of the electrode mounting seat 112b. The electrode sheet 111 is arranged at one end of the electrode mounting seat 112b away from the first connecting rod, and the elastic reset member 112e is connected between the electrode mounting seat 112b and the base 112a. The rotation axis of the first connecting rod is parallel to the rotation axis of the second connecting rod, and the length direction of the electrode mounting seat 112b is parallel to the telescopic direction.

[0054] The rotation axes of the first connecting rod 112c and the second connecting rod 112d are parallel, which ensures that the telescopic member 112 can maintain stability and consistency when moving, and avoids distortion or shaking caused by non-parallel rotation axes.

[0055] In this embodiment, the first connecting rod 112c and the second connecting rod 112d are respectively rotatably connected between the base 112a and the electrode mounting seat 112b, forming a parallelogram-like upgraded bracket structure. This design allows the electrode mounting seat 112b to move in the telescopic direction when subjected to external force (such as the extrusion of the insulating rod M), thereby adjusting the contact pressure between the electrode sheet 111 and the insulating rod M. The electrode sheet 111 is arranged at one end of the electrode mounting seat 112b. When the electrode mounting seat 112b moves, the electrode sheet 111 also moves therewith. Since the elastic reset member 112e is connected between the electrode mounting seat 112b and the base 112a, the electrode sheet 111 is kept in stable contact with the insulating rod M, preventing the electrode sheet 111 and the electrode mounting seat 112b from being damaged due to excessive extrusion, and at the same time ensuring that the electrode sheet 111 is kept in close contact with the effective insulating surface of the insulating rod M, so that it can be adaptively adjusted according to the diameter of the insulating rod M, ensuring that the measuring assembly can tightly wrap the insulating rods M of different diameters, and improving the accuracy of the measurement. In addition, when the external force disappears, the elastic reset member 112e can also provide a restoring force to return the electrode mounting seat 112b and the electrode sheet 111 to their initial positions.

[0056] like Figure 2-6 As shown, in some embodiments, the rotation axis of the first connecting rod and the rotation axis of the second connecting rod are respectively perpendicular to the extension direction of the annular cavity. And\or multiple electrode surface contact components 110 are evenly arranged in the annular cavity along the circumference of the annular cavity.

[0057] In some embodiments, the rotation axis of the first connecting rod and the rotation axis of the second connecting rod are respectively perpendicular to the extension direction of the annular cavity, so that when the electrode sheet 111 is subjected to external force, the first connecting rod 112c and the second connecting rod 112d can rotate in a plane perpendicular to the extension direction of the annular cavity (i.e., perpendicular to the axial direction of the insulating rod M), thereby driving the electrode mounting seat 112b and the electrode sheet 111 to move, so that the multiple electrode surface contact components 110 will not interfere with each other when extending and retracting, which helps to maintain parallel contact between the electrode sheet 111 and the surface of the insulating rod M, thereby improving the measurement accuracy.

[0058] In some embodiments, multiple electrode surface contact components 110 are evenly spaced in the annular cavity along the circumference of the annular cavity, ensuring that the test component 100 can fully cover the effective insulating surface of the insulating rod M, avoiding measurement errors caused by insufficient contact area. At the same time, the evenly distributed electrode surface contact components 110 also help improve the stability and consistency of the measurement.

[0059] like Figure 2-4 As shown, in some embodiments, the first part 120 and the second part 130 are rotatably connected via a rotating shaft. The rotating axis of the rotating shaft is parallel to the extending direction of the annular cavity.

[0060] In this embodiment, when the insulation resistance of the insulating rod M needs to be measured, the operator can relatively rotate the first part 120 and the second part 130 to open the annular cavity and place the insulating rod M therein. Then, the first part 120 and the second part 130 are relatively rotated again to close the annular cavity, so that the electrode surface contact assembly 110 and the insulating rod M are in close contact.

[0061] like Figure 7 As shown, the present application also provides a detection device, comprising: a plurality of insulation resistance detection devices 1000 as in any of the above embodiments, a data acquisition device, a data analysis device and a control device. The data acquisition device is connected to the plurality of insulation resistance detection devices 1000, and the data acquisition device is used to collect and convert measurement data. The data analysis device is connected to the data acquisition device, and the data collected by the data analysis device is analyzed and processed to determine the insulation change trend of the measured insulating rod M for prediction. The control device is connected to the data analysis device, and the control device is connected to the insulation resistance detection device 1000.

[0062] The insulation resistance detection device 1000 uses a specific measurement circuit and algorithm to measure the insulation resistance of the insulation rod M under test. Exemplarily, by applying a certain voltage, the current measurement data flowing through the insulation rod M under test is measured. The data acquisition device is connected to multiple insulation resistance detection devices 1000 to collect measurement data in real time. The data analysis device receives the measurement data transmitted by the data acquisition device, processes and analyzes or converts the data, and determines the insulation change trend of the insulation rod M under test by analyzing the trend and characteristics of the data, and makes a prediction, providing a scientific basis for subsequent maintenance, replacement and other decisions.

[0063] The control device is connected to the data analysis device and the insulation resistance detection device 1000, and is responsible for the control and scheduling of the entire test process. According to the results of the data analysis device, the control device can adjust the measurement parameters of the insulation resistance detection device 1000, or trigger alarms, shutdowns, and other actions. The control device can monitor the test process in real time, ensure the safety and stability of the test process, and avoid equipment damage or personal injury caused by improper testing.

[0064] At the same time, according to the detection equipment of the embodiment of the present application, the insulation resistance detection devices 1000 of multiple insulating rods M work in parallel, which significantly improves the test efficiency and shortens the test cycle.

[0065] In some embodiments, the data analysis device includes a first analysis module and a second analysis module connected in parallel, the first analysis module and the second analysis module are respectively connected to the data acquisition device, and by comparing the analysis results of the two modules, they can verify each other to obtain a more comprehensive analysis result, thereby improving the accuracy of the analysis.

[0066] Exemplarily, when the analysis results of the first analysis module and the second analysis module are the same, it is a normal state, and when the analysis results of the first analysis module and the second analysis module are abnormal, it is an abnormal state.

[0067] like Figure 7 As shown, according to any of the aforementioned embodiments of the second aspect of the present application, it also includes a detection cabinet 2000 and a detection door body 3000. The detection cabinet 2000 includes a human-machine interface and a detection chamber with a detection door. Each insulation detection device is arranged in the detection chamber. An electromagnetic lock is arranged on the detection door body 3000, and the detection door body 3000 is installed on the detection door.

[0068] According to the embodiments of the present application, users can interact with the device through a human-machine interface, such as setting test parameters, starting tests, viewing test results, etc. The human-machine interface provides clear operating instructions and feedback, making the test process more intuitive and easy to understand.

[0069] One or more test chambers are provided inside the test cabinet 2000 to accommodate the tested insulating rod M and the insulation test device. The design of the test chamber should ensure that a stable and interference-free test environment can be provided to reduce the influence of external factors on the test results.

[0070] A detection door is provided at the front or side of the detection chamber to open or close the chamber. The detection door should be designed to facilitate users to quickly and safely access the equipment and objects in the chamber. An electromagnetic lock is installed on the detection door body 3000 to control the opening and closing of the door.

[0071] After the test is completed, the tester will automatically stop measuring and unlock the electromagnetic lock, allowing the operator to open the detection door. The operator can remove the insulating rod M and view the measurement results displayed on the human-machine interface or generate a test report. During the entire test process, if the operator attempts to open the detection door before the test is completed, the safety interlock mechanism of the electromagnetic lock will prevent this behavior. If the detection door is accidentally opened or forced to open, the device will immediately cut off the power supply and stop all measurement activities to ensure the safety of the operator and the protection of the equipment.

[0072] like Figure 8 As shown, the present application also provides a detection method for a detection device, using the detection device of any of the aforementioned embodiments of the second aspect, the detection method comprises the following steps:

[0073] S10: placing the insulating rod M to be tested into the chamber to be tested, and obtaining data parameters of the insulating rod M;

[0074] S20 obtains test parameters according to the data parameters and starts the detection equipment to perform the test;

[0075] S30 acquires test data and analyzes the test data to obtain a test result;

[0076] S40 determines the insulation performance of the insulating rod M according to the detection result.

[0077] In this embodiment, when placing one or more insulating rods M into the detection device in the detection chamber of the detection equipment, the operator needs to ensure that the detection equipment is in normal working condition and check whether all connecting lines and safety facilities are intact. Then the operator opens the detection door, and the electromagnetic lock of the door body is in the unlocked state. Make sure that each insulating rod M is placed correctly for subsequent measurement and motion control. After confirming that all insulating rods M are correctly placed and clamped, and the first part 120 and the second part 130 of the test assembly 100 are buckled, the operator closes the detection door body 3000 of the detection equipment. At the same time, the electromagnetic lock will automatically lock to form a safety chain to ensure that the detection door body 3000 will not be accidentally opened during the detection process.

[0078] The operator sets the number of detection points of the corresponding insulating rod M and the distance between adjacent detection points of the insulating rod M according to the length dimension data of the insulating rod M measured by the distance measuring sensor 500, and starts the detection. By converting the detection data, the insulation resistance value of each detection position is obtained, and the insulation performance of the corresponding insulating rod M is evaluated according to the insulation resistance value to obtain an analysis result or an analysis report. After the test is completed, the detection equipment will automatically stop measuring and unlock the electromagnetic lock, allowing the operator to open the detection door.
