Description

Technical Field

[0001] This invention relates to the field of density relay debugging technology, and in particular to an automatic debugging device, method and system for a density relay pointer structure. Background Technology

[0002] Density relays are widely used in SF6 electrical engineering equipment such as high-voltage circuit breakers, high-voltage transformers, and high-power transformers to monitor and control the density of SF6 gas within the sealed containers of such equipment. A failure in a density relay can cause significant economic losses. To ensure the reliability of circuit breaker operation, it is essential to frequently monitor the various parameters of the density relay, especially the SF6 gas concentration, ensuring it meets relevant standards and maintaining the SF6 density relay in good working condition over the long term.

[0003] The density value of SF6 gas is a crucial indicator for the insulation and arc extinguishing of SF6 electrical engineering equipment. Therefore, the accuracy and reliability of the SF6 density relay's readings and contact values ​​are essential for the normal and safe operation of SF6 electrical engineering equipment on the national power grid. Current density relays typically use a Bourdon tube pressure gauge as the indicator of the pressure within the relay's cavity. To ensure the Bourdon tube pressure gauge accurately displays the current pressure value, it needs to be calibrated and adjusted before leaving the factory. Similarly, the Bourdon tube pressure gauge corresponding to the density relay also requires calibration.

[0004] Therefore, during the commissioning process of density relays, it is necessary to ensure that the pointer of the density relay can correctly indicate the preset pressure value. In existing production lines, this work is generally done manually. However, since adjusting the pointer indication accuracy is the most time-consuming and difficult process in the entire production process, this position not only requires high employee skills but is also relatively inefficient, becoming a bottleneck that is difficult to overcome in the production process of density relays. Generally speaking, an experienced employee can only complete the commissioning of 60-70 units per day, which is very inefficient. Therefore, an automatic commissioning device and system for the pointer structure of density relays is needed to solve the above problems. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the technical problem to be solved by the present invention is to provide an automatic debugging device, method and system for density relay pointer structure, so as to solve the problem of low efficiency caused by manual debugging of density relay pointer in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention provides an automatic adjustment device for a density relay pointer structure. The density relay pointer structure includes a Bourdon tube, a pull rod, a transmission rod, a spindle, a central gear, and a pointer mounted on the rotating shaft of the central gear. One end of the pull rod is connected to one end of the Bourdon tube, and the middle part of the transmission rod is rotatably connected to the spindle. One end of the transmission rod is provided with an adjustment groove, and the other end of the pull rod is located in the adjustment groove. The other end of the transmission rod is provided with a sector gear that meshes with the central gear. Under pressure, one end of the Bourdon tube moves and drives the pull rod to move. The pull rod then drives the transmission rod to rotate around the spindle. The sector gear at the other end of the transmission rod drives the central gear, causing the pointer to deflect. By adjusting the position of the other end of the pull rod in the adjustment groove, the force applied by the pull rod to the transmission rod is adjusted, thereby controlling the rotation angle of the transmission rod and adjusting the pointer rotation angle. The automatic adjustment device is used to adjust the density relay pointer structure so that when the Bourdon tube is subjected to a preset pressure, its pointer can indicate the correct pressure value. The automatic adjustment device includes:

[0007] A pressurizing unit is provided for connection to one end of the spring tube and for applying pressure into the spring tube.

[0008] An image acquisition unit is positioned directly opposite the density relay pointer structure to acquire image information of the density relay pointer structure.

[0009] The adjustment unit includes a drive motor and an adjustment screw connected to the drive motor. The adjustment screw is connected to the other end of the pull rod. The drive motor rotates to drive the adjustment screw to extend or retract, thereby driving the pull rod to move in the adjustment groove, thereby adjusting the rotation angle of the corresponding pointer.

[0010] A preset pressure is applied into the spring tube using a pressurizing unit, causing the pointer to rotate. Then, an image acquisition unit is used to acquire image information of the density relay pointer structure and establish a virtual dial. Finally, based on the deviation angle of the pointer on the virtual dial, the required adjustment distance of the other end of the pull rod in the adjustment groove is obtained. The drive motor is then controlled to rotate the adjustment screw, causing the adjustment screw to move the pull rod to the target position, so that the pointer correctly indicates the correct pressure value under the preset pressure.

[0011] As a more preferred embodiment, the automatic adjustment device for the density relay pointer structure further includes a gripper unit, which is disposed between the density relay pointer structure and the image acquisition unit. The gripper unit is used to install the pointer and ensures that the initial position of the pointer is accurate based on the virtual dial established by the image acquisition unit.

[0012] As a more preferred embodiment, the gripper unit includes a gripper bracket and an electric gripper disposed on the gripper bracket. The electric gripper grips the pointer and mounts the pointer onto the central gear according to the virtual dial.

[0013] As a preferred approach, the drive motor is a stepper motor. The stepper motor can more accurately control the rotation angle of the adjusting screw, and its excellent start-stop and reverse response also ensures the accuracy required for the adjustment of the density relay pointer structure.

[0014] As a more preferred embodiment, the pressurization unit includes an air pump and an air pipe leading from the air pump. The air pipe is connected to a spring tube. The air pump inflates or deflates the spring tube to move one end of the spring tube. The air pump pressurizes the spring tube, making the operation simple and easy to control.

[0015] As a more preferred approach, the automatic adjustment device for the density relay pointer structure also includes a pressure sensor for detecting the pressure applied to the Bourdon tube, thus enabling the pressure applied to the Bourdon tube to be obtained more quickly and accurately.

[0016] To address the aforementioned problems, the present invention also provides an automatic debugging method for a density relay pointer structure, and an automatic debugging system employing the aforementioned density relay pointer structure, comprising:

[0017] When a preset pressure is applied into the Bourdon tube using a pressurizing unit, the pointer rotates.

[0018] The image acquisition unit is used to acquire image information of the density relay pointer structure and a virtual scale is established.

[0019] Based on the virtual dial, obtain the pointer's deviation angle 'a', the distance 'b' between the pointer and the target position, and the distance 'L' between the other end of the lever and the spindle. Then, use the formula... The required adjustment distance L1 at the other end of the lever is calculated, where n is the preset magnification factor of the pointer deflection, which is determined by the gear ratio of the central gear and the sector gear.

[0020] The control drive motor rotates the adjusting screw, causing the adjusting screw to move the pull rod to the target position, so that the pointer correctly indicates the correct pressure value under the preset pressure.

[0021] To address the above problems, the present invention also provides a data processing device, comprising:

[0022] The device includes a memory for storing computer programs and a processor for executing the computer programs stored in the memory to enable the data processing device to perform an automatic debugging method for the density relay pointer structure described above.

One end of the transmission rod has an adjustment groove, and the other end of the pull rod is located within the adjustment groove. The other end of the transmission rod also has a sector gear that meshes with the central gear. Under pressure, one end of the Bourdon tube moves, driving the pull rod to move. The pull rod then drives the transmission rod to rotate around the spindle. The sector gear at the other end of the transmission rod drives the central gear, causing the pointer to deflect. The other end of the Bourdon tube is connected to the pressurization unit.

[0039] like Figure 1As shown, the present invention provides an automatic adjustment device 1 for a density relay pointer structure 3. The density relay pointer structure 3 includes a spring tube 31, a pull rod 32, a transmission rod 33, a spindle 35, a central gear, and a pointer 36 disposed on the rotating shaft of the central gear. One end of the pull rod 32 is connected to one end of the spring tube 31, and the middle part of the transmission rod 33 is rotatably connected to the spindle 35. One end of the transmission rod 33 is provided with an adjustment groove 331, and the other end of the pull rod 32 is disposed in the adjustment groove 331. The other end of the transmission rod 33 is provided with a sector gear that meshes with the central gear. Under pressure, the other end of the spring tube 31... One end moves and drives the pull rod 32 to move, which in turn drives the transmission rod 33 to rotate around the spindle 35. The sector gear at the other end of the transmission rod 33 drives the central gear to deflect the pointer 36. By adjusting the position of the other end of the pull rod 32 in the adjustment groove 331, the force applied by the pull rod 32 to the transmission rod 33 is adjusted, thereby controlling the rotation angle of the transmission rod 33 and thus adjusting the rotation angle of the pointer 36. The automatic adjustment device 1 is used to adjust the density relay pointer structure 3 so that when the spring tube 31 is subjected to a preset pressure, its pointer 36 can indicate the correct pressure value. The automatic adjustment device 1 includes:

[0040] A pressurizing unit is used to connect to one end of the spring tube 31 and can apply pressure to the spring tube 31;

[0041] Image acquisition unit 11, which faces the density relay pointer structure 3, to acquire image information of the density relay pointer structure 3;

[0042] The adjustment unit includes a drive motor 12 and an adjustment screw 15 connected to the drive motor 12. The adjustment screw 15 is connected to the other end of the pull rod 32. The drive motor 12 rotates to drive the adjustment screw 15 to extend or retract, thereby driving the pull rod 32 to move in the adjustment groove 331, thereby adjusting the rotation angle of the corresponding pointer 36.

[0043] A preset pressure is applied into the spring tube 31 using a pressurizing unit, causing the pointer 36 to rotate. Then, the image acquisition unit 11 acquires the image information of the density relay pointer structure 3 and establishes a virtual dial 39. Finally, based on the deviation angle of the pointer 36 on the virtual dial 39, the required adjustment distance of the other end of the pull rod 32 in the adjustment groove 331 is obtained. The drive motor 12 is then controlled to rotate the adjusting screw 15, causing the adjusting screw 15 to move the pull rod 32 to the target position, so that the pointer 36 correctly indicates the correct pressure value under the preset pressure.

[0044] In use, the automatic adjustment device 1 for the density relay pointer structure 3 of the present invention fixes the density relay pointer structure 3 to the automatic adjustment device 1. Then, a preset pressure is applied into the spring tube 31 using a pressurizing unit, causing the pointer 36 to rotate. The image acquisition unit 11 then acquires image information of the density relay pointer structure 3 and establishes a virtual dial 39. Finally, based on the deviation angle of the pointer 36 on the virtual dial 39, the required adjustment distance of the other end of the pull rod 32 in the adjustment groove 331 is obtained. The drive motor 12 is controlled to rotate the adjusting screw 15, causing the adjusting screw 15 to drive the pull rod 32 to the target position, so that the pointer 36 correctly indicates the correct pressure value under the preset pressure. This completes the automatic adjustment of the density relay pointer structure 3 and improves the adjustment efficiency.

[0045] Furthermore, in this embodiment, as Figure 2 As shown, the adjustment unit also includes an adjustment sleeve 13 and a motor bracket 14. The drive motor 12 is connected to the adjustment screw 15 through the adjustment sleeve 13, and the motor bracket 14 is used to help fix the drive motor 12.

[0046] In this embodiment, as Figure 1 As shown, the automatic adjustment device 1 of the density relay pointer structure 3 further includes a gripper unit 16. The gripper unit 16 is disposed between the density relay pointer structure 3 and the image acquisition unit 11. The gripper unit 16 is used to install the pointer 36 and ensure that the initial position of the pointer 36 is accurate according to the virtual dial 39 established by the image acquisition unit 11.

[0047] In this embodiment, as Figure 1 As shown, the gripper unit 16 includes a gripper bracket 162 and an electric gripper 161 disposed on the gripper bracket 162. The electric gripper 161 grips the pointer 36 and mounts the pointer 36 onto the central gear according to the virtual dial 39.

[0048] In this embodiment, the drive motor 12 is a stepper motor. The stepper motor can more accurately control the rotation angle of the adjusting screw 15. At the same time, its excellent start-stop and reverse response also ensures the accuracy required for debugging the density relay pointer structure 3.

[0049] In this embodiment, the pressurization unit includes an air pump and an air pipe leading out from the air pump. The air pipe is connected to the spring tube 31. The air pump fills and releases air into the spring tube 31 so that one end of the spring tube 31 moves. The spring tube 31 is pressurized by the air pump, which is simple to operate and easy to control.

[0050] In this embodiment, the automatic adjustment device 1 of the density relay pointer structure 3 further includes a pressure sensor for detecting the pressure on the spring tube 31, so that the pressure applied to the spring tube 31 can be obtained more quickly and accurately through the pressure sensor.

[0051] To address the aforementioned problems, the present invention also provides an automatic debugging method for the density relay pointer structure 3, comprising:

[0052] When a preset pressure is applied into the spring tube 31 using a pressurizing unit, the pointer 36 rotates.

[0053] The image acquisition unit 11 is used to acquire image information of the density relay pointer structure 3 and a virtual dial 39 is established.

[0054] Based on the virtual dial 39, obtain the deviation angle 'a' of the pointer 36 and the interval angle 'b' between the pointer 36 and the target position, as well as the distance 'L' between the other end of the pull rod 32 and the spindle 35, according to the formula. The required adjustment distance L1 at the other end of the lever 32 is calculated, where n is the preset magnification factor of the pointer 36 deflection, which is determined by the gear ratio of the central gear and the sector gear.

[0055] The control drive motor 12 rotates the adjusting screw 15, causing the adjusting screw 15 to drive the pull rod 32 to the target position, so that the pointer 36 correctly indicates the correct pressure value under the preset pressure.

[0056] The automatic debugging method for the density relay pointer structure 3 provided by this invention gives the automatic debugging process of the density relay pointer structure 3, and also provides an algorithm to calculate the required adjustment distance L1 of the other end of the pull rod 32 based on the virtual dial 39, making the whole debugging process more efficient.

[0057] In this embodiment, the formula The method for obtaining this is that, because the distance one end of the spring tube 31 moves is fixed under a fixed pressure, therefore in this embodiment, as... Figure 3 As shown, the downward displacement distance H of the spring tube 31 is fixed; simultaneously, according to the magnification, the deviation angle 'a' of the pointer 36 and the interval angle 'b' between the pointer 36 and the target position correspond to the rotation angles of the transmission rod 33 as n*a and n*b, respectively. Based on the lever principle, the following abstraction is obtained: Figure 3 The graph shown represents the desired adjustment distance, where L1 is the desired adjustment distance.

[0058] Next, we can obtain the following from trigonometric functions: ;
