[0050] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0051] To address the problems in the related art, the present disclosure provides an inter-pole spacing detection device and method. The inter-pole spacing detection device includes a first drive device, a mounting bracket, a sensing component, a detection module, and a control unit. The mounting bracket connects the sensing component and the first drive device. The detection component is used to obtain the rotation angle of the mounting bracket around a preset rotation axis. The control unit is used to determine the spacing between the anode plate and the cathode wire based on the first signal, second signal, and rotation angle generated by the sensing component and the detection module. In the embodiment of the present application, the inter-pole spacing is determined by the first drive device driving the sensing component to rotate around the preset rotation axis so as to contact the anode plate and cathode wire respectively. This solves the problem of poor detection results of conventional radar and visual methods due to the diffuse dust and low visibility in the electrostatic precipitator room.

[0052] According to an exemplary embodiment of the present disclosure, Figure 1As shown, this embodiment provides an inter-electrode spacing detection device 100, which can be used to detect the distance between the anode plate 200 and the cathode line 300 in the electrostatic precipitator room to avoid the substandard inter-electrode spacing in the electrostatic precipitator room affecting the dust removal efficiency and energy consumption, and to avoid safety hazards.

[0053] like Figures 1 to 3 As shown, the inter-pole distance 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 rotation axis so that the sensing component 30 can contact the anode plate 200 and the cathode line 300 respectively, thereby performing inter-pole distance detection.

[0054] In some embodiments, see Figures 1 to 3 The first drive device 10 can be a servo motor, the output shaft of which is connected to the mounting bracket 20. The servo motor can output torque to drive the mounting bracket 20 to rotate about a preset rotation axis. During the detection process, the inter-pole spacing detection device 100 is disposed between the anode plate 200 and the cathode wire 300. The forward and reverse rotation of the servo motor can cause the sensing component 30 to 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 rotation axis, or the axial direction of the output shaft can be non-parallel to the preset rotation axis by providing a helical gear, a universal coupling, etc.

[0055] In other embodiments (not shown in the drawings), the first drive device can also be a drive unit that outputs linear motion, such as an electric push rod, a cylinder, etc., and the linear motion can be converted into rotational motion by setting a transmission mechanism (such as a gear rack transmission mechanism) between the first drive device and the mounting bracket. No further details will be given.

[0056] like Figure 1 and Figure 2 As shown, the sensing component 30 is disposed on the mounting bracket 20 , and the sensing component 30 is configured to generate a first signal when contacting the anode plate 200 , and to generate a second signal when contacting the cathode line 300 .

[0057] In some embodiments, the sensing component 30 includes a sensor, such as a first driving device 10 that drives the sensing component 30 to rotate in a first direction until the sensor generates an electrical signal (generated electrical signal indicates that the sensing component 30 is in contact with the anode plate 200), and the 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 of the first direction until an electrical signal is generated again (generated electrical signal again indicates that the sensing component 30 is in contact with the cathode line 300), and the signal is recorded as the second signal.

[0058] In other embodiments, the sensing assembly 30 includes at least two sensors, and the two sensors can be of the same or different types. For example, when the two sensors are of the same type, the positions of the two sensors can be adjusted so that the two sensors can contact the anode plate 200 and the cathode line 300 respectively, thereby generating the first signal and the second signal separately.

[0059] like Figures 1 to 3 As shown, the inter-pole spacing detection device 100 also includes a detection module (not shown in the drawings), which is connected to the first drive device 10. The detection module can obtain the rotation angle of the mounting bracket 20 around the preset rotation axis through the driving action of the first drive device 10. In one example, the first drive 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 drive device 10 is an electric push rod, which drives the mounting bracket 20 to rotate through a gear 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 and thus determine the rotation angle, and the angle sensor can detect the gear to determine the rotation angle.

[0060] like Figure 1 As shown, the inter-pole spacing detection device 100 also includes a control unit (not shown in the drawings), which is electrically connected to the detection module and the sensing assembly 30. The control unit is not particularly limited in this embodiment. The control unit is capable of receiving the first and second signals from the sensing assembly 30, as well as the rotation angle of the detection module. In addition, the control unit also stores the length of the mounting bracket 20, i.e., the rotation radius.

[0061] In some embodiments, the length of the mounting bracket 20 remains constant, and the chord length, ie, the distance between the anode plate 200 and the cathode line 300 , can be directly calculated according to the rotation angle and the length of the mounting bracket 20 .

[0062] In other embodiments, see Figure 4 The length of the mounting bracket 20 will change with the rotation angle. The chord length can be calculated segment by segment by combining the first signal, the second signal and the rotation angle to obtain the spacing between the anode plate 200 and the cathode line 300.

[0063] In this embodiment, the first driving device drives the sensing component to rotate around a preset rotation axis to determine the inter-electrode distance by respectively touching the anode plate and the cathode line, thereby solving the problem of poor detection effect of conventional radar and visual methods caused by dust diffusion and low visibility in the electrostatic precipitator room.

[0064] In an exemplary embodiment, Figure 1As shown, this embodiment provides an inter-pole spacing detection device 100, which 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, and the detection 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 line 300 based on the first signal, the second signal and the rotation angle generated by the sensing component 30 and the detection module.

[0065] Among them, such as Figure 2 and Figure 3 As shown, the sensing assembly 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 assembly 30 contacts the cathode wire 300, tension is applied to the detection rope 32, causing it to straighten. When the first drive 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, the extension direction of the detection rope 32 in the straightened state forms an angle with the extension direction of the cathode wire 300. This arrangement 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, ensuring that the distance detected when the detection rope 32 contacts the cathode wire 300 is equal at all locations.

[0066] 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. The first bracket 21, the second bracket 22 and the third bracket 23 are all rod-shaped structures. The first end of the first bracket 21 is connected to the output shaft of the first driving device 10, and the second bracket 22 and the third bracket 23 are both 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 to switch the mounting bracket 20 between the Y-shape and the I-shape. For example, refer to Figure 1 、 Figure 2 and Figure 4 The tension sensor 31 of the sensing component 30 is arranged at the end of the second bracket 22 away from the first bracket 21, and 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, so that the position of the cathode line 300 can be determined by the detection rope 32.

[0067] Among them, such as Figures 1 to 4As shown, the sensing assembly 30 further includes a pressure sensor 33, which is disposed at an end of the mounting bracket 20 away from the first driving device 10, such as an end of the second bracket 22 away from the first bracket 21, or an 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 assembly 30 toward the anode plate 200, the second bracket 22 and the third bracket 23 can approach each other so that the mounting bracket 20 forms an I-shape, so that the pressure sensor 33 contacts the anode plate 200, thereby determining the position of the anode plate 200. It can be understood that the cathode line 300 in the electrostatic precipitator room is a discharge electrode, and the anode plate 200 is a dust-striking electrode, that is, the 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 inter-pole spacing detection device 100, the inter-pole spacing detection device 100 can be placed at a position farther away from the anode plate 200 while ensuring that the detection points of the inter-pole spacing detection device 100 on the anode plate 200 and the cathode line 300 are at the same height, thereby reducing or avoiding dust on the anode plate 200 from falling onto the inter-pole spacing detection device 100.

[0068] Among them, such as Figure 3 As shown, the mounting bracket 20 further 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 via 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 the Y-shape, the detection rope 32 is in a straightened state, and the position of the cathode wire 300 can be determined via the tension sensor 31 and the detection rope 32.

[0069] In some embodiments, the second driving device 40 can be an electric push rod, the output shaft of which is provided with a rack 41, the extension direction of the rack 41 being parallel to the linear output direction of the electric push rod, and the second bracket 22 and the third bracket 23 are provided with a gear 42, which meshes with the rack 41 to convert the linear motion output by the electric push rod into rotational motion of the second bracket 22 and the third bracket 23. In one embodiment, when the output shaft of the electric push rod is extended, the second bracket 22 and the third bracket 23 can be moved away from each other, thereby straightening the detection rope 32.

[0070] Among them, such as Figure 1As shown, the inter-pole spacing detection device 100 also includes a wall-climbing robot (not shown in the drawings), and the first driving device 10 is arranged on the wall-climbing robot. The wall-climbing robot is used to move the inter-pole spacing detection device 100 along the axial direction of the preset rotating shaft to detect the spacing between each cathode line 300 and the anode plate 200 in the electrostatic precipitator room.

[0071] According to an exemplary embodiment of the present disclosure, this embodiment further provides a method for detecting inter-pole spacing, the method comprising the following steps:

[0072] Step S110: Control the first driving device to drive the mounting bracket and the sensing component to move around the preset rotation axis along a first direction until the sensing component generates a first signal.

[0073] Step S120: Control the first driving device to drive the mounting bracket and the sensing component to move around the preset rotation axis in the second direction until the sensing component generates a second signal, and the first direction is opposite to the second direction.

[0074] Step S130: Determine the rotation angle of the mounting bracket and the sensing component around the preset rotation axis according to the first signal and the second signal.

[0075] Step S140: Determine the distance between the anode plate and the cathode line according to the rotation angle and the arm length of the mounting bracket.

[0076] In step S110 and step S120, the first driving device 10 drives the mounting bracket 20 and the sensing component 30 to rotate in the first direction and the second direction successively, so as to determine the positions of the anode plate 200 and the cathode line 300 successively. The method of determining the position is, for example, that the sensing component 30 detects a certain tension or pressure. The principle has been explained in the aforementioned structural side embodiment and will not be repeated here.

[0077] In step S130, the first signal and the second signal serve as the detection module to record the starting and ending signals of the rotation angle. For example, when the control unit receives the first signal, the angle previously recorded by the detection module is reset and recording is restarted. When the control unit receives the second signal, the detection module is controlled 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.

[0078] 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, where 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 angles is the distance between the anode plate 200 and the cathode line 300.

[0079] In one example, the interpole spacing is m·sinα+n·sinβ

[0080] In this embodiment, the first driving device 10 drives the sensing component 30 to rotate around a preset rotation axis to determine the inter-electrode distance by respectively touching the anode plate 200 and the cathode line 300, thereby solving the problem of poor detection effect of conventional radar and visual methods caused by dust diffusion and low visibility in the electrostatic precipitator room.

[0081] In some embodiments, this embodiment further illustrates step S120 in the aforementioned embodiment. In the process of controlling the first driving device 10 to drive the mounting bracket 20 and the sensing assembly 30 to move around the preset rotation axis in the second direction, the inter-pole spacing detection method further includes the following steps:

[0082] Step S121: Control the second driving device to drive the second bracket and the third bracket to move relative to each other, so that the detection rope is in a straightened state and the extending direction is perpendicular to the extending direction of the cathode line.

[0083] In this step, the second driving device 40 is controlled to drive the second bracket 22 and the third bracket 23 of the mounting bracket 20 to rotate to a Y shape, so that the detection rope 32 is in a straightened state. The straightened detection rope 32 is convenient for contacting the cathode line 300, which can improve the detection accuracy.

[0084] In some embodiments, this embodiment is a further explanation of step S120. In the process of controlling the actions of the first drive device 10 and the second drive device 40, the pole spacing detection method may further include the following steps:

[0085] Step S122: Control the wall-climbing robot to travel a preset distance along the extending direction of the detection rope, where the preset distance is less than or equal to half the length of the detection rope.

[0086] It is understandable that after determining the position of the anode plate 200, this step utilizes the time required for the first drive device 10 and the second drive device 40 to drive the mounting bracket 20 and the sensing assembly 30 toward the cathode line 300, thereby improving detection efficiency.

[0087] For example, see Figure 5 The pressure sensor 33 of the sensing assembly 30 in the inter-electrode distance detection device 100 contacts the anode plate 200 at point A. When the inter-electrode distance detection device 100 does not move in the x direction, the sensing assembly 30 is rotated to contact the cathode line 300 ( Figure 5 As shown in the dotted line in FIG, it can be determined that the middle of the detection rope 32 is in contact with the cathode wire 300. Figure 6 , showing the inter-pole distance detection device 100 Figure 5 The position moves along the x direction for a preset distance, and the end of the detection rope 32 contacts the cathode line 300. If the inter-electrode spacing detection device 100 at this position rotates the sensing component 30 to contact the anode plate 200 ( Figure 6 ), it can be determined that the pressure sensor 33 will contact the anode plate 200 at position A'.

[0088] Combine 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, wherein the first drive device 10 drives the mounting bracket 20 and the sensing component 30 to move toward the cathode line 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 inter-pole distance 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 inter-pole distance 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 is in contact with the cathode line 300 to generate the second signal.

[0089] In some embodiments, this embodiment is a further explanation of step S110 in the above embodiment. Step S110 includes the following steps:

[0090] Step S111: controlling the second driving device to drive the second bracket and the third bracket to move relative to each other, so as to reduce the angle between the second bracket and the third bracket.

[0091] This has been explained in the above embodiments and will not be described in detail here.
