[0045] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0046] To address the problems in related technologies, this disclosure provides an electrode spacing detection device. The device includes a first driving device, a mounting bracket, a sensing component, a detection module, and a control unit. The mounting bracket connects the sensing component and the first driving device. The detection component acquires the rotation angle of the mounting bracket around a preset axis. The control unit determines the spacing between the anode plate and the cathode wire based on a first signal, a second signal, and the rotation angle generated by the sensing component and the detection module. In this embodiment, the electrode spacing is determined by the first driving device driving the sensing component to rotate around a preset axis to contact the anode plate and the cathode wire respectively. This solves the problem of poor detection performance of conventional radar and visual methods due to dust concentration and low visibility in electrostatic precipitators.

[0047] According to an exemplary embodiment of this disclosure, such as Figure 1 As shown, this embodiment provides an electrode spacing detection device 100, which can be used to detect the spacing between the anode plate 200 and the cathode wire 300 in the electrostatic precipitator, so as to avoid the impact of substandard electrode spacing on dust removal efficiency and energy consumption, and to avoid safety hazards.

[0048] like Figures 1 to 3 As shown, the interpole spacing detection device 100 includes a first driving device 10, a mounting bracket 20, and a sensing component 30. The mounting bracket 20 is used to connect the first driving device 10 and the sensing component 30. The first driving device 10 can drive the mounting bracket 20 and the sensing component 30 to rotate around a preset axis so that the sensing component 30 can contact the anode plate 200 and the cathode wire 300 respectively, thereby performing interpole spacing detection.

[0049] In some embodiments, see Figures 1 to 3The first driving device 10 can be a servo motor. The output shaft of the servo motor is connected to the mounting bracket 20. The servo motor can output torque to drive the mounting bracket 20 to rotate around a preset axis. During the detection process, the electrode spacing detection device 100 is set between the anode plate 200 and the cathode wire 300. The forward and reverse rotation of the servo motor can make the sensing component 30 contact the anode plate 200 and the cathode wire 300 respectively, thereby generating corresponding electrical signals. In this embodiment, the axial direction of the output shaft of the servo motor is not limited. For example, the output shaft of the servo motor can be parallel to the preset axis, or the axial direction of the output shaft can be made not parallel to the preset axis by setting helical gears, universal couplings, etc.

[0050] In other embodiments (not shown in the figures), the first driving device may also be a driving unit that outputs linear motion, such as an electric push rod or a cylinder. The linear motion can be converted into rotational motion by setting a transmission mechanism (such as a gear and rack transmission mechanism) between the first driving device and the mounting bracket, which will not be elaborated further.

[0051] like Figure 1 and Figure 2 As shown, the sensing component 30 is disposed on the mounting bracket 20. The sensing component 30 is configured to generate a first signal when in contact with the anode plate 200 and a second signal when in contact with the cathode wire 300.

[0052] In some embodiments, the sensing component 30 includes a sensor. For example, the first driving device 10 drives the sensing component 30 to rotate in a first direction until the sensor generates an electrical signal (generating an electrical signal indicates that the sensing component 30 is in contact with the anode plate 200), and this signal is used as the first signal. After the sensing component 30 generates the first signal, the first driving device 10 drives the sensing component 30 to rotate in the opposite direction in the first direction until an electrical signal is generated again (generating an electrical signal again indicates that the sensing component 30 is in contact with the cathode wire 300), and this signal is recorded as the second signal.

[0053] In other embodiments, the sensing component 30 includes at least two sensors, which may be of the same or different types. For example, when the two sensors are of the same type, their positions can be adjusted so that they can contact the anode plate 200 and the cathode wire 300 respectively, thereby generating a first signal and a second signal separately.

[0054] like Figures 1 to 3As shown, the interpole spacing detection device 100 also includes a detection module (not shown in the figures). The detection module is connected to the first driving device 10. The detection module can obtain the rotation angle of the mounting bracket 20 around a preset axis through the driving action of the first driving device 10. In one example, the first driving device 10 can be a servo motor, and the detection module can be an encoder. The encoder can detect the number of pulses of the servo motor to determine the rotation angle. In another example, the first driving device 10 is an electric push rod. The electric push rod drives the mounting bracket 20 to rotate through a gear and rack transmission mechanism. The detection component can be a distance sensor or an angle sensor. The distance sensor can detect the movement distance of the rack to determine the rotation angle, and the angle sensor can detect the gear to determine the rotation angle.

[0055] like Figure 1 As shown, the interpole spacing detection device 100 also includes a control unit (not shown in the figures), which is electrically connected to the detection module and the sensing component 30. In this embodiment, the control unit is not limited in many ways. The control unit can receive the first and second signals from the sensing component 30, as well as the rotation angle of the detection module. Additionally, the control unit stores the length of the mounting bracket 20, i.e., the rotation radius.

[0056] In some embodiments, the length of the mounting bracket 20 remains constant, so the chord length, i.e. the distance between the anode plate 200 and the cathode line 300, can be directly calculated based on the rotation angle and the length of the mounting bracket 20.

[0057] In other embodiments, see Figure 4 The length of the mounting bracket 20 will change with different rotation angles. Therefore, the chord length can be calculated segment by segment by combining the first signal, the second signal and the rotation angle to obtain the distance between the anode plate 200 and the cathode line 300.

[0058] In this embodiment, the electrode spacing is determined by driving the sensing component to rotate around a preset axis through the first driving device so that it can contact the anode plate and the cathode wire respectively. This solves the problem that the dust in the electrostatic precipitator room is diffused and the visibility is low, which leads to poor detection results of conventional radar and vision methods.

[0059] In one exemplary embodiment, such as Figure 1 As shown, this embodiment provides an electrode spacing detection device 100. The electrode spacing detection device 100 includes a first driving device 10, a mounting bracket 20, a sensing component 30, a detection module, and a control unit. The mounting bracket 20 connects the sensing component 30 and the first driving device 10. The sensing component is used to obtain the rotation angle of the mounting bracket 20 around a preset rotation axis. The control unit is used to determine the spacing between the anode plate 200 and the cathode wire 300 based on the first signal, the second signal, and the rotation angle generated by the sensing component 30 and the detection module.

[0060] Among them, such as Figure 2 and Figure 3 As shown, the sensing component 30 includes a tension sensor 31 and a detection rope 32. The tension sensor 31 is mounted on the mounting bracket 20, one end of the detection rope 32 is connected to the tension sensor 31, and the other end of the detection rope 32 is mounted on the mounting bracket 20. When the sensing component 30 contacts the cathode wire 300, the detection rope 32 will be stretched and become straight. When the first driving device 10 drives the mounting bracket 20 to move, causing the detection rope 32 to contact the cathode wire 300, the detection rope 32 is stretched, causing the tension sensor 31 to generate a second signal. In this embodiment, when the detection rope 32 is in a straight state, its extension direction forms an angle with the extension direction of the cathode wire 300. This setting makes it easier for the detection rope 32 to contact the cathode wire 300, thereby improving detection accuracy. Furthermore, the extension direction of the detection rope 32 is parallel to the anode plate 200, which ensures that the detected distance is equal when the detection rope 32 contacts the cathode wire 300 at various positions.

[0061] In one example, the detection rope 32 can be an elastic element made of an elastic material.

[0062] Among them, such as Figure 3 As shown, the mounting bracket 20 includes a first bracket 21, a second bracket 22, and a third bracket 23. All three brackets are rod-shaped structures. The first end of the first bracket 21 is connected to the output shaft of the first drive device 10. The second bracket 22 and the third bracket 23 are rotatably connected to the second end of the first bracket 21. The second bracket 22 and the third bracket 23 can rotate relative to the first bracket 21, allowing the mounting bracket 20 to switch between a Y-shape and an I-shape. For example, see [reference needed]. Figure 1 , Figure 2 and Figure 4 The tension sensor 31 of the sensing component 30 is located at the end of the second bracket 22 away from the first bracket 21. The detection rope 32 is connected to the end of the third bracket 23 away from the first bracket 21. When the mounting bracket 20 is in a Y-shape, the detection rope 32 can be straightened, thereby determining the position of the cathode wire 300 through the detection rope 32.

[0063] Among them, such as Figures 1 to 4As shown, the sensing component 30 also includes a pressure sensor 33, which is disposed at the end of the mounting bracket 20 away from the first driving device 10. For example, it can be disposed at the end of the second bracket 22 away from the first bracket 21, or at the end of the third bracket 23 away from the first bracket 21. When the first driving device 10 drives the mounting bracket 20 and the sensing component 30 to move toward the anode plate 200, the second bracket 22 and the third bracket 23 can move closer to each other, making the mounting bracket 20 form an I-shape, so that the pressure sensor 33 contacts the anode plate 200 to determine the position of the anode plate 200. It is understandable that in the electrostatic precipitator, the cathode wire 300 is the discharge electrode, while the anode plate 200 is the dust-collecting electrode. That is, dust is usually adsorbed on the anode plate 200. Since the I-shaped mounting bracket 20 is longer than the Y-shaped mounting bracket 20, when planning the travel path of the electrode spacing detection device 100, it is possible to place the electrode spacing detection device 100 at a position farther away from the anode plate 200, while ensuring that the detection point height of the electrode spacing detection device 100 on the anode plate 200 and the cathode wire 300 is the same, thereby reducing or preventing dust on the anode plate 200 from falling onto the electrode spacing detection device 100.

[0064] Among them, such as Figure 3 As shown, the mounting bracket 20 also includes a second drive device 40. The output shaft of the second drive device 40 is connected to the second bracket 22 or the third bracket 23. The second drive device 40 is used to drive the second bracket 22 and the third bracket 23 to rotate relative to the first bracket 21, so that the mounting bracket 20 switches between an I-shape and a Y-shape, thereby determining the positions of the cathode wire 300 and the anode plate 200 by the tension sensor 31 and the pressure sensor 33, respectively. For example, when the first bracket 21, the second bracket 22, and the third bracket 23 are in a Y-shape, the detection rope 32 is in a taut state, thereby determining the position of the cathode wire 300 by the tension sensor 31 and the detection rope 32.

[0065] In some embodiments, the second driving device 40 can be an electric actuator. The output shaft of the electric actuator is provided with a rack 41, the extension direction of which is parallel to the linear output direction of the electric actuator. The second bracket 22 and the third bracket 23 are provided with gears 42, and the rack 41 meshes with the gears 42 to convert the linear motion output by the electric actuator into the rotational motion of the second bracket 22 and the third bracket 23. In one example, when the output shaft of the electric actuator extends, it can cause the second bracket 22 and the third bracket 23 to move away from each other, thereby straightening the detection rope 32.

[0066] Among them, such as Figure 1As shown, the electrode spacing detection device 100 also includes a wall-climbing robot (not shown in the figure). The first drive device 10 is disposed on the wall-climbing robot. The wall-climbing robot is used to move the electrode spacing detection device 100 along the axial direction of a preset rotating shaft to detect the spacing between each cathode wire 300 and anode plate 200 in the electrostatic precipitator.

[0067] According to an exemplary embodiment of this disclosure, this embodiment also provides a method for detecting interpole spacing, the method comprising the following steps:

[0068] Step S110: Control the first driving device to drive the mounting bracket and sensing component to move around the preset rotating axis in the first direction until the sensing component generates the first signal.

[0069] Step S120: Control the first driving device to drive the mounting bracket and sensing component to move around the preset rotating axis in the second direction until the sensing component generates a second signal, and the first direction is opposite to the second direction.

[0070] Step S130: Determine the rotation angle of the mounting bracket and sensing component around the preset axis based on the first signal and the second signal.

[0071] Step S140: Determine the spacing between the anode plate and the cathode wire based on the rotation angle and the arm length of the mounting bracket.

[0072] In steps S110 and S120, the first driving device 10 drives the mounting bracket 20 and the sensing component 30 to rotate sequentially along the first direction and the second direction, thereby determining the positions of the anode plate 200 and the cathode line 300. The position is determined by means such as the sensing component 30 detecting a certain tension or pressure. The principle has been explained in the aforementioned structural embodiment and will not be repeated here.

[0073] In step S130, the first signal and the second signal serve as the start and end signals for the detection module to record the rotation angle. For example, when the control unit receives the first signal, it resets the angle previously recorded by the detection module and restarts recording. When the control unit receives the second signal, it controls the detection module to stop recording. The angle recorded by the detection module during the period when the control unit receives the first signal and the second signal is the rotation angle.

[0074] In step S140, in some embodiments, the rotation angle can be divided into a first angle α and a second angle β along the vertical line. The first angle α is located on the side of the vertical line facing the anode plate 200, and the second angle β is located on the side of the vertical line facing the cathode line 300. The distance between the vertical line and the anode plate 200 can be calculated based on the length m when the sensing component 30 contacts the anode plate 200 and the first angle α. The distance between the vertical line and the cathode line 300 can be calculated based on the length n when the sensing component 30 contacts the cathode line 300 and the second angle β. The sum of the two is the distance between the anode plate 200 and the cathode line 300.

[0075] In one example, the interelectrode spacing is m·sinα+n·sinβ

[0076] In this embodiment, the first driving device 10 drives the sensing component 30 to rotate around a preset axis to determine the electrode spacing by contacting the anode plate 200 and the cathode wire 300 respectively. This solves the problem that dust and low visibility in the electrostatic precipitator room lead to poor detection results of conventional radar and visual methods.

[0077] In some embodiments, this embodiment is a further explanation of step S120 in the foregoing embodiments. During the process of controlling the first driving device 10 to drive the mounting bracket 20 and the sensing component 30 to move around a preset axis in the second direction, the polarity detection method further includes the following steps:

[0078] Step S121: Control the second drive device to drive the second bracket and the third bracket to move relative to each other so that the detection rope is in a straight state and the extension direction is perpendicular to the extension direction of the cathode wire.

[0079] In this step, the second drive device 40 is controlled to drive the second bracket 22 and the third bracket 23 of the mounting bracket 20 to rotate into a Y shape so that the detection rope 32 is in a straight state. The straightened detection rope 32 is easier to contact with the cathode wire 300, which can improve the detection accuracy.

[0080] In some embodiments, this embodiment is a further explanation of step S120. During the process of controlling the operation of the first driving device 10 and the second driving device 40, the interpole spacing detection method may further include the following steps:

[0081] Step S122: Control the wall-climbing robot to travel a preset distance along the extension direction of the detection rope. The preset distance is less than or equal to half the length of the detection rope.

[0082] It is understandable that after determining the position of the anode plate 200, this step utilizes the time required for the first driving device 10 and the second driving device 40 to drive the mounting bracket 20 and the sensing component 30 toward the cathode line 300, thereby improving detection efficiency.

[0083] For example, see Figure 5 In the electrode spacing detection device 100, the pressure sensor 33 of the sensing component 30 contacts the anode plate 200 at point A. Without moving the electrode spacing detection device 100 along the x-direction, the sensing component 30 is rotated until it contacts the cathode wire 300. Figure 5 The dotted line shown indicates that the center of the detection rope 32 is positioned where it will contact the cathode wire 300. (See attached image.) Figure 6 The polar spacing detection device 100 is shown to be composed of Figure 5 After moving a preset distance along the x-direction, the end of the detection rope 32 contacts the cathode wire 300. If the interpole spacing detection device 100 at this position rotates the sensing component 30 to contact the anode plate 200, ( Figure 6 As shown by the dashed line, it can be determined that the pressure sensor 33 will contact the anode plate 200 at position A'.

[0084] Combination Figure 5 and Figure 6 It can be determined that after the pressure sensor 33 generates the first signal, the wall-climbing robot, the first drive device 10, and the second drive device 40 are started simultaneously. The first drive device 10 drives the mounting bracket 20 and the sensing component 30 to move toward the cathode wire 300, and the second drive device 40 drives the mounting bracket 20 to deform so that the detection rope 32 is straightened. The wall-climbing robot is used to realize the movement of the interpole spacing detection device 100 along the x-direction. It can be understood that since the detection rope 32 extends along the x-direction, even if the interpole spacing detection device 100 moves a preset distance (less than or equal to half the length of the detection rope 32) along the x-direction, it can still ensure that the detection rope 32 contacts the cathode wire 300 to generate the second signal.

[0085] In some embodiments, this embodiment is a further explanation of step S110 in the foregoing embodiments. Step S110 includes the following steps:

[0086] Step S111: Control the second drive device to drive the second bracket and the third bracket to move relative to each other, so as to reduce the included angle between the second bracket and the third bracket.

[0087] As explained in the foregoing embodiments, it will not be repeated here.
