Description

Technical Field

[0001] This utility model relates to the field of electrostatic precipitator technology, specifically to a dust removal device for an electrostatic precipitator electrode plate system. Background Technology

[0002] During the operation of an electrostatic precipitator, the electrode system (including anode plates and cathode wires) is exposed to the flue gas environment for extended periods, easily accumulating large amounts of dust. If it is not cleaned promptly and effectively, it will lead to decreased dust removal efficiency, abnormal electric field distribution, and may even cause equipment breakdown and shutdown risks. Therefore, regular dust cleaning and maintenance of the electrode system has become one of the key measures to ensure the stable operation of the electrostatic precipitator.

[0003] Most existing dust removal operations rely on manual operation or semi-automatic equipment, which generally suffer from low efficiency, poor consistency, and significant safety hazards. Manual cleaning is not only labor-intensive but also poses high risks when operating in high-temperature, electrified, or confined spaces, especially at heights or in narrow areas where it is difficult to apply stable force, often resulting in unsatisfactory cleaning effects. Furthermore, traditional equipment struggles to meet the different cleaning needs of the anode plate surface and cathode wire structure, lacking adaptability in dust removal pressure control and brush structure matching, which can easily lead to problems such as excessively rapid brush wear or damage to the electrode plates.

[0004] On the other hand, the cleaning effect after dust removal usually relies on visual inspection or experience, lacking a quantitative assessment method for the thickness of residual dust. This makes it impossible to reasonably adjust the cleaning frequency and intensity according to the actual residue, easily leading to over-cleaning or under-cleaning, which not only affects the operating efficiency of the electrode system but also increases maintenance costs. Therefore, there is an urgent need for a more integrated and automated dust removal device that can adapt to the complex structure of the electrode system to improve cleaning efficiency, control cleaning quality, and ensure operational safety.

Detailed Implementation

[0020] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0021] In this embodiment of the utility model, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use.

[0022] The terms “first,” “second,” “third,” etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0023] The terms "horizontal," "vertical," and "sag" do not imply that a component must be absolutely horizontal, vertical, or sagging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

[0024] Furthermore, terms like "roughly" and "basically" are used to indicate that the content does not require absolute precision, but rather allows for a certain degree of deviation. For example, "roughly equal" does not simply mean absolute equality; in actual production and operation, achieving absolute "equality" is difficult, and a certain degree of deviation is generally present. Therefore, besides absolute equality, "roughly equal to" also includes the aforementioned situation where a certain degree of deviation exists. Using this as an example, in other cases, unless otherwise specified, terms like "roughly" and "basically" have similar meanings.

[0025] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Figure 1 This is a structural diagram of a dust removal device for an electrostatic precipitator plate system according to one embodiment of the present invention. Figure 1 As shown, this invention provides a dust removal device for an electrostatic precipitator electrode plate system. The device includes: a main frame 1 for mounting various working modules; a dust removal module 2, including an electrode plate roller brush device 5 and an electrode wire direct brush device 6; wherein, the electrode plate roller brush device 5 is installed at the front end of the main frame 1 for cleaning the surface of the anode plate in the electrostatic precipitator electrode plate system; the electrode wire direct brush device 6 is installed at the rear end of the upper surface of the main frame 1 for cleaning the surface of the cathode wire in the electrostatic precipitator electrode plate system; an adsorption and walking module 3 is installed at the four corners of the main frame 1 for magnetically adsorbing the device onto the surface of the anode plate and driving the device to move; and a thickness measuring device is installed at the rear end of the main frame 1 for detecting the thickness of residual dust on the surface of the anode plate to determine whether more thorough cleaning is needed.

[0028] Preferably, the main frame 1 is provided with multiple grooves for installing various working modules; wherein, each working module includes a battery module, a control module, an acceleration sensor module, a dust removal module 2, a thickness measurement module 4, and an adsorption walking module 3; the main frame 1 has an adjustable support structure for installation at different height positions in the electrostatic precipitator plate system.

[0029] In this embodiment of the invention, the main frame 1 is provided with multiple grooves for installing various working modules, thereby achieving positional constraints and structural protection of the modules, and improving the stability and integration of the device in the high-temperature, high-dust, and strong electric field environment inside the electrostatic precipitator electrode system. Specifically, the working modules include: a battery module for providing power to the entire device; a control module for scheduling the actions of various components; an acceleration sensor module for judging the device's operating status and attitude changes; a dust removal module 2 for performing anode plate and cathode wire cleaning tasks; a thickness measurement module 4 for performing dust residue thickness detection; and an adsorption and walking module 3 for adsorption adhesion and propelling the device.

[0030] Each of the aforementioned working modules is positioned and fixed using matching structural grooves according to its size, weight, and installation location requirements. For example, the battery module and control module are preferably located in the middle of the main frame 1, with groove positioning to reduce center of gravity shift; the dust removal module 2 is installed on the front and rear upper surfaces of the main frame 1, and its relative position with the anode plate and cathode wire must be precisely consistent, therefore its mounting groove is equipped with a limiting structure to ensure accurate working path; while the adsorption and walking module 3 is fixed at the four corners of the main frame 1, symmetrically arranged in the grooves to ensure balanced torque during independent four-wheel drive; the thickness measurement module 4 is installed at the rear end of the main frame 1, with corresponding guide rail grooves for vertical movement in conjunction with the thickness measurement mechanism. This structural arrangement not only makes the overall structure compact and the modules clearly divided, but also facilitates later assembly, inspection, and maintenance.

[0031] Furthermore, to accommodate different models or specifications of electrostatic precipitators, the main frame 1 preferably features an adjustable support structure. This structure includes retractable connecting components or sliding rail devices, allowing adjustment of the cleaning height based on the spacing between the anode plates and cathode wires in the electrostatic precipitator's electrode system. For example, in some devices where the distance between the anode plates and cathode wires is less than 200mm, the adjusted main frame 1 can precisely position the roller brush and straight brush devices in front of and above the target cleaning surface, achieving close contact between the brush body and the target surface. This not only avoids blind spots but also ensures that interference with the electrode plates is avoided during cross-plate movement, improving movement stability and structural adaptability.

[0032] Preferred, such as Figure 2 and Figure 3The electrode plate roller brush device 5 includes: a roller brush 7, hinged to a roller brush mounting base 9, the roller brush having multiple rows of bristles, the bristles being alternating steel wires and soft rubber bristles, the steel wires being used to brush away clumps of dust, and the soft bristles being used to clean surface dust particles; the roller brush mounting base 9, hinged to a roller brush pressure rotating shaft 12 and a main frame 1, the roller brush pressure rotating shaft 12 being driven by a roller brush pressure motor 10, causing the roller brush to move up and down; a roller brush rotation motor 8, used to drive the roller brush to rotate; the roller brush pressure motor 10, used to drive the roller brush pressure rotating shaft 12 to rotate, thereby causing the roller brush to apply cleaning pressure; the roller brush pressure motor 10 has a built-in torque sensor, used to adjust the pressure applied by the roller brush to the surface of the anode plate.

[0033] In this embodiment of the invention, the electrode plate roller brush device 5 is used to mechanically clean the surface of the anode plate in the electrode plate system of the electrostatic precipitator. Its structural composition and functional design take into account both the requirements of efficient dust removal and flexible bonding under complex dust conditions. Specifically, the electrode plate roller brush device 5 includes: a roller brush, a roller brush mounting base 9, a roller brush rotation motor 8, a roller brush pressure motor 10, a roller brush pressure rotation shaft 12, and a hinge mechanism between the roller brush and the roller brush support 11.

[0034] The roller brush 7 has a cylindrical structure with multiple rows of bristles on its surface. These bristles are composed of alternating steel wires and rubber bristles, arranged in a repeating pattern of "one row of steel wires + one row of rubber bristles," for a total of 12 rows. This mixed arrangement is designed based on the adhesion characteristics of dust particles: the steel wires are used to powerfully remove dust clumps that have adhered due to high temperature and humidity; the rubber bristles are used to clean smaller dust particles remaining on the anode plate surface, thus reducing wear on the anode plate while ensuring cleaning power. This is particularly suitable for actual working conditions where the dust layer is uneven in thickness and the particles are highly adhesive. Taking some steel plant dust collectors as an example, clumps of dust often appear on the anode plate surface, which cannot be effectively removed by using only rubber bristles; steel wire bristles must be used in conjunction with these bristles to break them up.

[0035] The roller brush 7 is hinged to the roller brush mounting base 9 via a pin structure, allowing it to rotate within a certain range during cleaning, thus enhancing its contact and adhesion with the anode plate surface. The roller brush mounting base 9 is hinged to both the roller brush pressure rotating shaft 12 and the roller brush bracket 11 via a bidirectional connection structure. The roller brush pressure rotating shaft 12 is mounted with one end fixed and the other rotating, driven by the roller brush pressure motor 10, which in turn causes the roller brush to swing up and down. This pressure movement controls whether the roller brush contacts the anode plate at different times, facilitating obstacle avoidance or lifting. A bushing and limiting structure are provided between the roller brush pressure rotating shaft 12 and the mounting base to ensure a stable and controllable pressure angle, preventing overpressure due to malfunction.

[0036] The roller brush rotation motor 8 is connected to one side of the roller brush's central shaft to provide rotational power for the roller brush, enabling continuous contact cleaning action of the bristles. This motor is preferably a high-temperature, dust-resistant DC motor, coupled with an adjustable speed drive controller to adapt to different dust types and electrode plate contamination levels. On the other hand, the roller brush pressure motor 10 is specifically used to control the roller brush's lifting angle and contact pressure. It integrates a torque sensor that can detect changes in output torque in real time and adjust control commands based on feedback, thereby achieving digital adjustment of the cleaning pressure applied by the roller brush to the anode plate. For example, when an excessive torque value is detected, the system can automatically reduce the downward pressure to prevent the roller brush from scratching the electrode plate surface or causing the device to jam.

[0037] In summary, the electrode plate roller brush device 5, through its rigid-flexible bristle structure, double-hinged support, and adjustable pressure lifting structure, not only effectively adapts to the cleaning needs of complex ash layers on the anode plate surface but also possesses strong environmental adaptability and operational stability. Combined with the closed-loop torque adjustment function of the roller brush pressurizing motor 10, it significantly improves the accuracy and safety of the cleaning action, laying a solid foundation for the automation and standardization of electrostatic precipitator cleaning operations.

[0038] Preferred, such as Figure 4 The electrode direct brush device 6 includes: a direct brush 13, with multiple rows of alternating soft bristles and steel wires, used to clean the surface of the cathode wire in the electrostatic precipitator electrode system; a direct brush pressure rotating shaft 15, hinged to the direct brush 13 and the direct brush bracket 16, the direct brush pressure rotating shaft 15 being driven to rotate by a roller brush pressure motor 10, causing the direct brush to move up and down and apply cleaning pressure; a direct brush pressure motor 14, used to drive the pressure rotating shaft to rotate, thereby causing the direct brush to apply cleaning pressure, the direct brush pressure motor 14 being equipped with a torque sensor, the pressure applied by the direct brush being adjusted by controlling the output torque; and a protective isolation cover, used to protect the direct brush pressure motor 14 and the direct brush pressure rotating shaft 15.

[0039] In this embodiment of the invention, the electrode wire direct brush device 6 is used to clean the surface of the cathode wire in the electrode plate system of the electrostatic precipitator. Its design focuses on solving the cleaning difficulties caused by the special structure of the cathode wire, such as its slender length, fragility, and suspended vibration, while adapting to the confined space and high-temperature, high-dust operating environment inside the electrode plate system. To this end, in this embodiment, the device has been specifically optimized in terms of structural composition, operation mode, and pressure control, enabling flexible contact with the cathode wire, uniform cleaning, and intelligent control.

[0040] Specifically, the polar line direct brush device 6 includes multiple structural components such as a direct brush, a direct brush pressure rotating shaft 15, a direct brush pressure motor 14, and a protective isolation cover.

[0041] The straight brush has a strip-shaped structure and is arranged at the rear end of the upper surface of the main frame 1. Structural constraints ensure that the movement path of its bristles is parallel to the direction of the cathode wire, guaranteeing uniform coverage of the wire during cleaning. The surface of the straight brush has multiple rows of bristles, arranged in an alternating pattern of "steel wire + soft rubber bristles," also consisting of one row of soft bristles and one row of steel wire, for a total of 12 rows. This hybrid bristle structure design is optimized based on the characteristics of cathode wire contamination. The soft bristles are used to clean adhered dust, while the steel wires are used to remove lightly clumps, while avoiding hard impacts or pulling, ensuring both cleaning effectiveness and structural safety. For example, after two months of operation on the cathode wire of a steel plant, a large area of ​​adsorbed particles appeared, but they did not form clumps. Using a pure steel wire brush would easily damage the wire, while this structure can balance flexibility and removal capability.

[0042] The straight brush is hinged to the straight brush pressure rotating shaft 15 via a pin structure. The other end of the rotating shaft is connected to the main frame 1, thus forming a controllable fulcrum for lifting and pressing. The straight brush pressure rotating shaft 15 is driven to rotate by the straight brush pressure motor 14 mounted on the main frame 1. By driving the shaft to swing, the straight brush is controlled to move up and down, realizing the switching between cleaning and non-operating states. This lifting structure not only maintains a certain adhesion pressure of the straight brush to the cathode wire surface during the cleaning phase, but also raises the brush body to a horizontal "suspended" state during non-cleaning phases such as crossing plates, turning, or changing direction, avoiding interference with the anode plate and improving the device's passability and protection.

[0043] The direct-brush pressure motor 14 is an intelligent motor with feedback function. It integrates a torque sensor to detect load changes during output shaft rotation in real time. The control module dynamically adjusts the applied pressure based on the torque feedback value. When abnormal force or severe vibration is detected on the cathode wire, it can automatically reduce the downward pressure or pause operation to prevent scratches, breakage, or displacement. This digital pressure regulation mechanism is more flexible, responsive, and safer than traditional constant-pressure cleaning methods.

[0044] Furthermore, to ensure the reliable operation of the aforementioned cleaning mechanism under high dust and high temperature conditions, the protective isolation cover is installed outside the direct brush pressurizing motor 14 and its rotating shaft. The cover is made of high-temperature corrosion-resistant materials (such as aluminum-magnesium alloy or heat-resistant composite materials), and has multiple functions such as preventing dust accumulation, preventing high-temperature radiation, and preventing electric field interference, effectively extending the service life of key components and improving the long-term stability of the device.

[0045] The electrode wire direct brush device 6 in this invention achieves efficient, safe, and intelligent cleaning of the cathode wires through a rigid-flexible brush body structure, a linked lifting mechanism, and a torque feedback control mechanism. Combined with the highly environmentally adaptable design of the protective isolation cover, it can replace manual labor in various industrial scenarios, realizing the automation and standardization of internal maintenance operations for electrostatic precipitators.

[0046] Preferred, such as Figure 5The adsorption walking module 3 includes: multiple magnetic wheels equipped with permanent magnets, used to adsorb the device onto the surface of the anode plate through the magnetic attraction between the permanent magnets and the anode plate; magnetic wheel protective rings 17 corresponding to each magnetic wheel, respectively installed on both sides of each magnetic wheel, used to protect the magnetic wheel during movement; a reducer 19, used to reduce the speed output of the drive motor 20 and transmit it to the magnetic wheel to match the walking speed requirements; and a drive motor 20, used to provide power output to the magnetic wheel; wherein, each magnetic wheel is connected to the reducer 19 and the drive motor 20 through a transmission shaft, forming a four-wheel independent drive structure.

[0047] In this embodiment of the invention, preferably, the adsorption-walking module 3 is used to drive the entire electrostatic precipitator electrode plate system cleaning device to achieve stable adhesion and controllable movement on the anode plate surface, ensuring the coverage and continuity of the cleaning process. The module is specifically optimized for complex working conditions such as high temperature, high dust, and strong electric field, and combines highly magnetic materials, independent drive structure, and protective components to improve overall operational capability and environmental adaptability.

[0048] Specifically, the adsorption and walking module 3 includes multiple magnetic wheels, preferably four, which are respectively installed at the four corners of the main frame 1 to form a three-dimensional and stable four-point support structure. Each magnetic wheel is a permanent magnet made of neodymium iron boron (NdFeB) material, which has high magnetic energy product, strong magnetic attraction, and good high-temperature stability. It can operate for a long time at the normal operating temperature of the anode plate of the electrostatic precipitator, around 140°C, without demagnetizing. The surface of the anode plate is a conductive metal plate structure, which can provide a sufficient closed magnetic field path to achieve a strong magnetic adsorption effect between the magnetic wheels and the anode plate, thereby effectively preventing the device from slipping on vertical or inclined surfaces and ensuring that the device is always firmly attached to the surface of the electrode plate.

[0049] To extend the service life of the magnetic wheel body and improve its wear resistance, a magnetic wheel protective ring 17 is provided on both sides of each magnetic wheel. This protective ring is preferably made of a high-polymer composite wear-resistant material and is tightly connected to the magnetic wheel using an embedded structure. Its function is to prevent the magnetic wheel from being scratched, bumped, or chipped due to contact with the edge of the anode plate or foreign objects during movement, and also to reduce the coefficient of friction, which helps to improve the smoothness of movement.

[0050] Each magnetic wheel is connected to the reducer 19 and the drive motor 20 via a drive shaft, forming an independent power output path and creating a four-wheel independent drive structure. The drive motor 20 is responsible for outputting rotational power; preferably, it is an industrial micro DC motor with high-temperature resistance and dustproof characteristics, and it is connected to the reducer 19 via a dedicated connector. The reducer 19 is used to reduce the high-speed, low-torque rotation output from the drive motor 20 to achieve an output state that matches the target moving speed of the device and improves the load capacity of the magnetic wheels. One end of the drive shaft is connected to the output end of the reducer 19, and the other end is embedded inside the magnetic wheel, forming a firm coupling with the magnetic wheel through keyed connections, splined connections, or embedded gears.

[0051] Specifically, to ensure the coordination of motion among the magnetic wheels and improve obstacle-crossing ability, the four magnetic wheels are driven independently. Their speed and direction can be adjusted separately by the control module, achieving coordinated dynamic control when crossing anode plates with different spacing, passing through corner areas, or compensating for local slippage. For example, when the left magnetic wheel experiences increased resistance due to interference from the edge of the anode plate, the control module can automatically increase its driving force to maintain overall posture stability.

[0052] The adsorption-walking module 3 provides strong adsorption through permanent magnet wheels. It forms an independent drive structure with a reducer 19 and a drive motor 20, and is further enhanced by a protective ring to improve operational reliability. This achieves stable adsorption and flexible movement under the complex operating conditions of the electrostatic precipitator, significantly improving the operating efficiency and safety of the cleaning device. The module has a compact structure, separate drive and control, and good expandability and versatility, making it widely applicable to automatic cleaning scenarios for various plate dust collectors.

[0053] Preferred, such as Figure 6 The thickness measuring module 4 includes: a thickness measuring probe 25, fixedly mounted on a probe fixing plate 22, used to detect the thickness of residual dust on the surface of the anode plate; the probe fixing plate 22 is connected to the bracket by a guide rod 26 passing through it and sliding up and down, with both ends of the guide rod 26 fixed to the thickness measuring module bracket 21; a miniature electric cylinder 27, symmetrically arranged on both sides of the thickness measuring module 4 bracket, fixed to the lower surface of the probe fixing plate 22, used to drive the probe fixing plate 22 to move up and down; and multiple springs 23, respectively sleeved on each guide rod 26, used to provide auxiliary elastic force during the extension and retraction of the miniature electric cylinder 27; wherein, when the miniature electric cylinder 27 extends, it compresses the spring 23, causing the thickness measuring probe 25 to rise; when the miniature electric cylinder 27 retracts, the spring 23 resets and assists the thickness measuring probe 25 to descend.

[0054] In this embodiment of the invention, the thickness measurement module 4 is used to detect the thickness of the residual dust layer on the surface of the anode plate in real time, so as to help determine the cleaning effect and whether repeated cleaning operations are needed, thereby improving the intelligence and precision of dust removal. The design of this module fully considers the characteristics of the operating environment of the electrostatic precipitator electrode plate system, such as high temperature, high dust, and confined space. It integrates precision measuring components, guide support structure and electronic control actuators, and has strong environmental adaptability and measurement stability.

[0055] The thickness measurement module 4 includes a thickness measurement probe 25, a probe fixing plate 22, a miniature electric cylinder 27, a guide rod 26, a spring 23, and a thickness measurement module bracket 21. The thickness measurement probe 25, employing the electromagnetic ultrasonic principle, is fixedly installed in the center of the probe fixing plate 22, providing non-contact measurement capabilities and accurately sensing the thickness of the adhering dust layer without damaging the anode plate surface structure. This type of probe is particularly suitable for environments with high dust levels and metallic backgrounds, featuring strong anti-interference capabilities and high repeatability.

[0056] To achieve probe lifting control, the probe fixing plate 22 is slidably connected to the thickness measurement module bracket 21 via two parallel guide rods 26. The two ends of the guide rods 26 are fixed to the upper and lower parts of the bracket, respectively, forming a stable vertical guide channel. The probe fixing plate 22 can move up and down along the guide rods 26, avoiding swaying and deviation during measurement and ensuring data accuracy.

[0057] The miniature electric cylinders 27 are mounted on the left and right sides of the thickness measurement module bracket 21, and their ends are bolted to the lower surface of the probe fixing plate 22. Each electric cylinder features rapid response and precise controllable stroke, enabling it to complete the probe lifting and lowering action within seconds. During the detection task, the electric cylinder output rod extends, driving the probe fixing plate 22 upward to adjust the distance to the anode plate surface; after the detection is completed, the electric cylinder retracts, and the probe descends, returning to the standby position.

[0058] To improve the rebound speed and stroke stability of the structure, each guide rod 26 is equipped with a spring 23. The spring 23 is located between the upper surface of the probe fixing plate 22 and the lower part of the bracket, and is in a slightly compressed state. On the one hand, the spring 23 provides auxiliary thrust during the retraction of the electric cylinder, making the probe descend more smoothly and avoiding excessive load on the electric cylinder; on the other hand, when the probe is accidentally obstructed (such as by touching the anode plate protrusion), it can absorb part of the impact force through elastic buffering, protecting the measuring element of the thickness measuring device from damage.

[0059] Through the above structure, the thickness measurement module 4 can complete the following workflow: After the detection command is issued, the miniature electric cylinder 27 extends to push the probe up to the preset measurement height. The probe performs the dust thickness acquisition task. After the measurement is completed, the electric cylinder retracts, and the probe returns to the protection position along with the probe fixing plate 22. Throughout the process, the guide rod 26 provides precise positioning, and the spring 23 assists in the return stroke, ensuring smooth and orderly measurement actions. Taking a typical working condition as an example, when the device moves in the detection area at the rear end of the operation, the thickness measurement module 4 automatically starts, the probe rises and collects data, and the output result shows that the residual dust thickness exceeds the set threshold. The system then instructs the dust removal module 2 to perform cleaning at the target position again, forming a closed-loop logic of "detection-feedback-re-sweep", which effectively improves the equipment operating efficiency and cleanliness assurance capability.

[0060] The thickness measurement module 4 integrates multiple functional components and achieves an efficient, safe, and intelligent dust residue detection mechanism through structural combination and electronic control. It has the advantages of compact structure, sensitive response, and strong adaptability, and is one of the key modules in the intelligent dust removal device of the electrostatic precipitator plate system.

[0061] Preferred, such as Figure 7 The device further includes an automatic opening and closing module 24 for protecting the thickness measuring probe 25; the automatic opening and closing module 24 includes a sliding groove fixing plate 28, which has a vertical sliding groove and a horizontal sliding groove for respectively accommodating the probe fixing plate 22 and the driven baffle 31 for sliding; a first connecting rod 29 and a second connecting rod 30, one end of which is hinged to the probe fixing plate 22 and the other end of which is hinged to the driven baffle 31, for realizing the conversion between vertical and horizontal movement; two driven baffles 31 are separately provided in the horizontal sliding groove of the sliding groove fixing plate 28, which can move horizontally under the drive of the connecting rod; wherein, one end of the probe fixing plate 22 is set as a slider structure, which is embedded in the vertical sliding groove of the sliding groove fixing plate 28. When the probe fixing plate 22 is raised and lowered by the electric cylinder, the first connecting rod 29 and the second connecting rod 30 drive the two driven baffles 31 to move towards or away from each other in the horizontal direction, thereby realizing the closing and opening of the opening below the thickness measuring probe 25.

[0062] In this embodiment of the invention, the device further includes an automatic opening and closing module 24. This module is used to mechanically protect the thickness probe 25 in the thickness measuring module 4, especially during measurement intervals or when the device is moving. By closing the structure, it prevents dust intrusion or foreign object impacts from damaging the probe assembly, thereby improving the reliability and service life of the device in complex, high-dust environments. The entire automatic opening and closing module 24 combines a mechanical structure linkage design with an electronic control triggering strategy. It can automatically and synchronously execute the door opening and closing action during the probe lifting and lowering movement, realizing closed-loop control of "automatic door opening during probe operation and automatic door closing after probe retrieval".

[0063] The automatic opening and closing module 24 includes: a slide rail fixing plate 28, a first connecting rod 29, a second connecting rod 30, and a driven baffle 31. The slide rail fixing plate 28 is the core supporting component, with a vertical slide rail for guiding the lifting and lowering of the probe fixing plate 22, and a horizontal slide rail for guiding the horizontal movement of the door. The slide rail fixing plate 28 is typically made of a single piece of milled metal, possessing sufficient strength and thermal stability to stably support the operation of multiple mechanisms over a long period.

[0064] One end of the probe fixing plate 22 is configured as a slider structure, which is stably embedded in the vertical groove of the slide rail fixing plate 28 to ensure that it does not wobble or jam during its up and down movement, providing a precise guiding reference for the probe's lifting and lowering. A first connecting rod 29 and a second connecting rod 30 are hinged to one side of the slider, extending to the left and right respectively, with their distal ends hinged to two driven baffles 31. The two driven baffles 31 are respectively arranged at both ends of the horizontal slide rail of the slide rail fixing plate 28, acting as a "door" structure. When the probe is not in operation, they are in a closed state, blocking the opening area below the probe; when the probe moves down to perform the measurement task, the connecting rods drive the driven baffles 31 to open to both sides, opening the measurement window.

[0065] The automatic opening and closing module 24 relies entirely on the movement of the probe lifting mechanism, requiring no additional electric drive or control commands. When the miniature electric cylinder 27 lifts the thickness measuring probe 25, the probe fixing plate 22 moves upward, causing the first connecting rod 29 and the second connecting rod 30 to retract vertically, thereby moving the two driven baffles 31 horizontally towards the center to close the opening area. Conversely, when the electric cylinder retracts, the probe fixing plate 22 descends, and the connecting rod structure pulls the driven baffles 31 open to both sides, opening the measurement window. This purely mechanical linkage method has high responsiveness and high reliability, is not easily affected by electrical control failures, and reduces the occupation of circuit wiring and control resources.

[0066] For example, during actual operation, when the device completes one cleaning cycle and prepares to move to the next plate segment, the thickness measurement module 4 retracts the probe, and the automatic opening and closing module 24 closes the lower window accordingly to prevent high-temperature dust from directly corroding the probe's bottom structure. Conversely, when the measurement program needs to be restarted, the window automatically opens as the probe descends again, ensuring that the measurement data is not affected by structural obstruction.

[0067] Overall, the automatic opening and closing module 24, through the double linkage and sliding groove mechanism, realizes a probe protection mechanism with compact structure, synchronized action, and accurate response, ensuring the stable operation of the precision measuring elements in the thickness measuring module 4, effectively extending the service life of the device, and reducing the maintenance frequency. It is an important auxiliary structure for improving the reliability of the dust removal device of the electrostatic precipitator plate system.
