Description

Technical Field

[0001] This utility model belongs to the field of equipment cleaning, specifically relating to a plate cleaning device and an electrostatic precipitator cleaning robot. Background Technology

[0002] Surface cleaning of plate-shaped components is a common requirement in industrial maintenance, especially in the field of electrostatic precipitators, where thorough cleaning of the anode plates and cathode wires directly affects the core performance of the equipment. These cleaning operations typically face two common challenges: firstly, the need to efficiently remove firmly adhered contaminants; and secondly, the necessity of operating within confined spaces or complex structures to avoid damage to the plates themselves or surrounding equipment. Therefore, developing a dedicated cleaning device that is efficient, adaptable, and plate-friendly is of universal significance.

[0003] Currently, cleaning methods for such plates mostly rely on simple tools or fixed mechanisms. While handheld brushes or high-pressure water guns are flexible, they are inefficient, produce uneven results, and pose safety hazards. Fixed cleaning mechanisms integrated into equipment have significant drawbacks: their drive units are often bulky, affecting layout within a compact space; the cleaning rollers and drive heads are often integrated or rigidly connected, resulting in poor flexibility and an inability to adapt to potential non-parallelism, easily causing cleaning blind spots or equipment wear; furthermore, the lack of quick-assembly and disassembly designs makes maintenance and workstation switching extremely inconvenient.

[0004] In the specific scenario of electrostatic precipitators, these limitations are further amplified. The internal space of the electrode assembly is extremely limited, the electrode spacing is small, and there is a complex support frame at the bottom. Existing cleaning equipment struggles to achieve a compact layout and precise guidance of the drive head, and cannot solve the problem of rapid switching of the cleaning rollers when obstructed by the bottom frame. This severely restricts the feasibility of continuous, automated cleaning of multiple electrode plates, resulting in low cleaning efficiency and failing to meet the requirements of modern industry for efficient and intelligent maintenance operations. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a board cleaning equipment and an electrostatic precipitator cleaning robot that has high cleaning capacity, high flexibility, can be quickly deployed and adapted to different board thicknesses.

[0006] This utility model provides a plate cleaning device, including two drive heads and two cleaning rollers; The drive head is provided with a rotary drive mechanism, which includes an output drive wheel. The drive head is also provided with two mounting clamps that rotate around the axis of the output drive wheel. The cleaning roller includes a mounting clamp, a cleaning roller body, and a driven wheel. The roller shafts of the driven wheel and the cleaning roller body are rotatably mounted on the mounting clamp, and the driven wheel is fixedly connected to the roller shaft of the cleaning roller body. The mounting clamp is detachably mounted on the mounting clamp. After the mounting clamp is engaged with the mounting clamp, the driven wheel meshes with the output drive wheel. The drive head is also equipped with an angle adjustment mechanism for adjusting the relative angle of the two mounting clamps.

[0007] Furthermore, the mounting chuck includes a housing and a rotating part connected to each other. The housing has a cavity with an opening at one end and a locking structure. The rotating part is rotatably connected to the drive head. The mounting clip can be detachably engaged into the cavity through the opening, and the mounting clip is provided with an engaging structure that cooperates with the engaging structure.

[0008] Furthermore, a positioning shaft is provided inside the drive head; One of the rotating parts is a hollow cylindrical structure with closed ends. The two ends of the cylindrical structure are rotatably engaged with the positioning shaft. The output drive wheel is located inside the cylindrical structure. One side of the cylindrical wall of the cylindrical structure is connected to the cavity, and the other side is provided with an arc-shaped groove that exposes the output drive wheel. The other rotating part consists of two rotating mounting plates, which are located at both ends of the cylindrical structure and are rotatably engaged with the positioning shaft. The arc-shaped groove connects to the cavity of this rotating part.

[0009] Furthermore, a guide structure is provided inside the cavity, and a guide engagement structure is provided on the side wall of the mounting block. The mounting block is fitted into the cavity through the sliding engagement of the guide engagement structure and the guide structure.

[0010] Furthermore, at least one of the rotary drive mechanisms includes a rotary drive member and a bevel gear set, wherein the rotary drive member is disposed perpendicular to the cleaning roller on the drive head; The bevel gear set connects the output drive wheel and the rotary drive component.

[0011] Furthermore, the angle adjustment mechanism includes a tension spring; Two sets of tension springs are used to drive the two sets of mounting clamps to move closer together at a small angle or further apart at a large angle.

[0012] Furthermore, the angle adjustment mechanism includes an upper positioning pin and a lower positioning pin disposed on the drive head housing, and an arc-shaped sliding groove disposed on the drive head housing; The mounting clamp is provided with a tension spring connecting pin that slides along an arc-shaped groove; Two tension springs are provided. One end of one tension spring is connected to a tension spring connecting pin of a mounting clamp, and the other end is connected to an upper or lower positioning pin. One end of the other tension spring is connected to a tension spring connecting pin of another mounting clamp, and the other end is connected to an upper or lower positioning pin.

[0013] Furthermore, the side of the drive head facing the cleaning roller is also provided with a guide wheel assembly that fits the plate to be cleaned.

[0014] Furthermore, the cleaning roller body includes a roller shaft and a plurality of brushes disposed on the roller shaft; The brush body includes plates and bristles distributed circumferentially, with the plates and bristles of adjacent sets of brush bodies arranged alternately.

[0015] This utility model also provides a cleaning robot for electrostatic precipitators, including the above-mentioned cleaning equipment, hoisting equipment and two sets of bottom switching equipment; The two cleaning rollers of the cleaning device are sandwiched between the two sides of a plate to be cleaned, and / or the two cleaning rollers are disposed between two plates to be cleaned, and each cleaning roller is in contact with a plate to be cleaned. The hoisting equipment is installed on top of the electrode plate assembly of the electrostatic precipitator system and is used to hoist the two drive heads to move up and down along the Z direction. Two sets of bottom switching devices are set at both ends of the bottom of the electrode assembly in the X direction. The bottom switching device includes a slide rail set along the Y direction of the electrode assembly and two receiving cylinders slidably set on the slide rail. The cleaning roller is detachably set on the drive head, and the end of the cleaning roller can be embedded in the receiving cylinder.

[0016] The cleaning equipment provided by this utility model has the following beneficial effects: 1. The output drive wheel directly meshes with the driven wheel on the cleaning roller, forming a rigid, slip-free transmission. This transmission method is highly efficient, ensuring that the cleaning roller receives sufficient and stable torque, providing a powerful scrubbing effect.

[0017] Second, the single rotary drive mechanism drives two mounting clamps simultaneously through one output drive wheel, ensuring that the two cleaning rollers can rotate in opposite directions in strict synchronization. This is crucial for balancing the force on both sides when clamping and washing a single electrode plate, and can effectively prevent the electrode plate from deforming due to uneven force.

[0018] Third, the cleaning roller achieves true modularity through the quick engagement and disengagement of the mounting clamps on the drive head and the mounting blocks. This makes the replacement, maintenance, and transfer of the cleaning roller on the bottom switching equipment extremely convenient.

[0019] In addition, when a cleaning roller needs maintenance or replacement, it can be removed independently without touching the entire drive unit, which greatly reduces maintenance time and costs.

[0020] IV. The angle adjustment mechanism allows the relative angle of the two mounting clamps to be adjusted within a certain range. This enables a pair of cleaning rollers to adaptively conform to the surfaces of two electrode plates that are not perfectly parallel (due to manufacturing or installation errors or deformation during long-term use). This adaptive capability ensures that the bristles or cleaning surface of the cleaning roller body maintains uniform and sufficient contact pressure with the electrode plates along their entire length, avoiding cleaning dead zones or uneven pressure caused by angle mismatch, thereby significantly improving cleaning quality and effectiveness.

[0021] Fifth, this design is not only specifically designed for the anode plates or cathode wires of electrostatic precipitators, but its flexible clamping and driving methods also make it suitable for cleaning other similar plate-shaped structures, thus expanding the application range of the equipment.

[0029] As attached Figure 1 -Appendix Figure 12 As shown, this utility model discloses a cleaning robot for electrostatic precipitators, used to clean the electrode plate assembly 4 of the electrostatic precipitator system. The structure of the electrode plate assembly 4 can be as follows: It includes an anode plate assembly and a cathode wire assembly. The anode plate assembly includes a top frame 42, a bottom frame 43 and several anode plates 411. The bottom frame 43 is hollow and is used to connect a dust hopper.

[0030] The top frame 42 includes two top longitudinal beams 421 arranged parallel to each other along the Y direction and several top transverse beams 422 arranged parallel to each other along the X direction, which are erected between the two top longitudinal beams 421. It also includes a top connecting beam 423 arranged along the Y direction to reinforce the several top transverse beams 422. The bottom frame 43 includes two bottom longitudinal beams 431 arranged parallel to each other along the Y direction and several bottom transverse beams 432 arranged parallel to each other along the X direction, which are erected between the two bottom longitudinal beams 431. The two top longitudinal beams 421 and the bottom longitudinal beams 431 are arranged in a rectangular pattern; The number of anode plates 411 is the same as the number of bottom crossbeams 432, and the lower end of one anode plate 411 is fixed on the bottom crossbeam 432, while the upper end is fixed on the top longitudinal beam 421.

[0031] The cathode wire assembly includes a cathode mounting frame 44 and a plurality of cathode wires 412. The cathode mounting frame 44 includes a lower frame 441, an upper frame 443, and a column 442 connecting the lower frame 441 and the upper frame 443. The lower frame 441 includes two cathode lower longitudinal beams 4411 arranged parallel to each other along the Y direction and several cathode lower transverse beams 4412 arranged parallel to each other along the X direction, which are erected between the two cathode lower longitudinal beams 4411. The upper frame 443 includes two cathode upper longitudinal beams 4431 arranged parallel to each other along the Y direction and several cathode upper transverse beams 4432 arranged parallel to each other along the X direction, which are erected between the two cathode upper longitudinal beams 4431. The two lower longitudinal beams 4411 and the upper longitudinal beam 4431 of the cathode are arranged in a rectangular pattern. The number of lower crossbeams 4412 and upper crossbeams 4432 of the cathode are the same and correspond one-to-one. Each set of corresponding lower crossbeams 4412 and upper crossbeams 4432 of the cathode is set between the two anode plates 411. A cathode wire 412 connects the lower cathode crossbeam 4412 and the upper cathode crossbeam 4432. The lower end of the cathode wire 412 is fixed to the lower cathode crossbeam 4412, and the upper end is fixed to the upper cathode crossbeam 4432. At this time, several anode plates 411 and several cathode wires 412 are arranged alternately in sequence. Preferably, between two anode plates 411, several cathode wires 412 are evenly distributed along the X direction, forming a structure similar to a cathode plate.

[0032] A dust removal duct is formed between the two anode plates 411. High voltage is passed between the anode plate 411 and the cathode wire 412. After the airflow carrying impurities and dust passes through the dust removal duct, the dust particles in the airflow become charged and are then captured onto the anode plate 411 under the action of the electric field.

[0033] This electrostatic precipitator cleaning robot includes a hoisting device 1, a cleaning device 2, and two sets of bottom switching devices 3; The cleaning device 2 includes two drive heads 21 and two cleaning rollers 22. One end of each cleaning roller 22 is fixed to one of the drive heads 21, and the other end is fixed to the other drive head 21. The two drive heads 21 and the two cleaning rollers 22 are arranged in a rectangular configuration, with the two drive heads 21 and the two cleaning rollers 22 parallel to each other. At least one of the drive heads 21 is used to drive the two cleaning rollers 22 to rotate. Preferably, the two drive heads 21 have identical structures and are used to synchronously drive the relative rotation of the two cleaning rollers 22. The two cleaning rollers 22 are sandwiched between two electrode plates 41 to be cleaned, and / or the two cleaning rollers 22 are positioned between two electrode plates 41 to be cleaned, with each cleaning roller 22 contacting one electrode plate 41 to be cleaned. There are three cleaning states for the two cleaning rollers 22. State 1: The two cleaning rollers 22 clean one electrode plate 41 to be cleaned. The cleaning rollers 22 are sandwiched between the two sides of the electrode plate 41 to be cleaned and clean both sides of the electrode plate 41 to be cleaned at the same time. At this time, the outer sides of the two cleaning rollers 22 do not contact other structures. State 2: The two cleaning rollers 22 clean two electrode plates 41 to be cleaned (cathode plate structures located on both sides of anode plate 411) at the same time. The outer sides of the two cleaning rollers 22 are used to clean the opposite sides of the two electrode plates 41 to be cleaned. At this time, the two cleaning rollers 22 are located between the two electrode plates 41 to be cleaned, and the outer side of one cleaning roller 22 is in contact with one side of the electrode plate 41 to be cleaned. State 3: The two cleaning rollers 22 clean three electrode plates 41 to be cleaned at the same time. At this time, the two cleaning rollers 22 are sandwiched between the two sides of one electrode plate 41 to be cleaned and clean both sides of the electrode plate 41 to be cleaned at the same time. The outer sides of the two cleaning rollers 22 are used to clean the opposite sides of the two electrode plates 41 to be cleaned. The electrode plate 41 to be cleaned can be an anode plate 411 and cathode plate structures located on both sides of the anode plate 411. In state one, the two cleaning rollers 22 are used only to clean the anode plate 411. In state two, the two cleaning rollers 22 are used only to clean the two cathode plate structures on both sides of the anode plate 411. In state three, the two cleaning rollers 22 clean both the anode plate 411 and the two cathode plate structures on both sides of the anode plate 411 simultaneously. It should be noted that in states one and two, the roller diameter (maximum diameter, i.e., the diameter of the brush body 2222) of the cleaning rollers 22 is smaller than the distance between the anode plate 411 and the cathode plate structures. In this case, the cleaning device 2 can adjust the angle of the two cleaning rollers 22 by setting the angle adjustment mechanism 213, thereby switching between states one and two. In state three, the diameter of the cleaning roller 22 is equal to the distance between the anode plate 411 and the cathode plate structure, meaning the axis of the cleaning roller 22 is located in the middle of the anode plate 411 and the cathode plate structure, allowing simultaneous cleaning of both. At this time, the cleaning equipment 2 can also be equipped with an angle adjustment mechanism 213 to accommodate anode plates 411 of different thicknesses.

[0034] refer to Figure 1 In the XYZ coordinate system, the hoisting equipment 1 is set on the top frame 42 of the electrode plate assembly 4 of the electrostatic precipitator system, and is used to hoist the two drive heads 21 to move up and down along the Z direction; the hoisting equipment 1 can be movably set on the top frame 42, or it can be directly erected on the top frame 42.

[0035] Two sets of bottom switching devices 3 are set at both ends of the bottom of the electrode assembly 4 in the X direction. The bottom switching device 3 includes a slide 31 set along the Y direction of the electrode assembly 4 and two receiving cylinders 32 slidably set on the slide 31. The slide 31 is set below the bottom frame 43 of the electrode assembly 4. The cleaning roller 22 is detachably mounted on the drive head 21, and the end of the cleaning roller 22 can be embedded in the receiving cylinder 32, thereby enabling the cleaning roller 22 to switch to the electrode plate 41 to be cleaned.

[0036] This utility model also provides a method for cleaning electrode plates in an electrostatic precipitator system, using the aforementioned electrostatic precipitator cleaning robot, including an installation stage, a cleaning stage, and a switching stage: The installation phase includes: Align the hoisting equipment 1 with the electrode plate 41 to be cleaned and install it onto the top frame 42 of the electrode plate assembly 4, and lower the two drive heads 21 to the bottom frame 43 of the electrode plate assembly 4. The two cleaning rollers 22 are installed from below the bottom frame 43 of the electrode assembly 4 onto the two drive heads 21 to complete the installation of the cleaning equipment 2; The cleaning phase includes: The hoisting equipment 1 pulls the two drive heads 21 and the two cleaning rollers 22 upward. The two cleaning rollers 22 are sandwiched on both sides of a plate 41 to be cleaned, and / or the two cleaning rollers 22 are arranged between two plates 41 to be cleaned, and each cleaning roller 22 is in contact with a plate 41 to be cleaned. The hoisting equipment 1 is reset, and the two drive heads 21 and two cleaning rollers 22 move downward by gravity; During the upward and / or downward movement of the two cleaning rollers 22, at least one of the drive heads 21 drives the two cleaning rollers 22 to rotate, thus brushing the electrode plate 41 to be cleaned. The switching phase includes: Install the bottom switching device 3 onto the bottom frame 43 of the electrode assembly 4; The hoisting equipment 1 lowers the two drive heads 21 and the two cleaning rollers 22 to above the bottom frame 43; The two cleaning rollers 22 are removed from the two drive heads 21 and fall into the receiving cylinder 32; Slide the receiving cylinder 32 along the slide 31 to the position of the next electrode plate 41 to be cleaned; The hoisting equipment 1 pulls the two drive heads 21 up to the top frame 42 of the electrode assembly 4, and then moves the hoisting equipment 1 and the two drive heads 21 to the position of the next electrode 41 to be cleaned. The hoisting equipment 1 lowers the two drive heads 21 to the bottom frame 43 of the electrode assembly 4, and installs the cleaning roller 22 in the receiving cylinder 32 into the drive head 21, thus completing the switching of the electrode 41 to be cleaned.

[0037] The cleaning robot for electrostatic precipitators provided by this utility model has the following beneficial effects: The cleaning equipment 2 adopts a rectangular layout with two drive heads 21 and two cleaning rollers 22, supporting three cleaning states (cleaning of a single electrode plate on both sides, cleaning of two electrode plates opposite sides, and cleaning of three electrode plates simultaneously), offering high flexibility. The cleaning rollers 22 rotate under the drive of the drive heads 21, brushing the electrode plates during their up-and-down movement. This results in a large coverage area, thorough cleaning, and effective removal of accumulated dust and impurities from the electrode plate surface, restoring the electrostatic precipitator's efficiency.

[0038] II. The hoisting equipment 1 is integrated on the top frame 42 of the electrode plate assembly 4, and can control the lifting and lowering of the drive head 21 and the cleaning roller 22, realizing the mechanization of the cleaning process. The bottom switching equipment 3, through the slide 31 and the receiving cylinder 32, allows for the quick disassembly and position switching of the cleaning roller 22, reducing the time for manual handling and adjustment, and lowering labor intensity. Specifically: The bottom of the electrode assembly 4 of the electrostatic precipitator (i.e., above the ash hopper) has a complex and crisscrossing structure, forming an obstacle zone. Traditional integrated cleaning equipment is almost unable to move or switch positions in this area. This invention solves this industry problem through the combined design of the detachable connection of the cleaning device 2 and the bottom switching device 3. Specifically, the lower frame 441 of the cathode wire assembly (including the lower cathode longitudinal beam 4411 and the lower cathode cross beam 4412) is located above or in the same space as the bottom frame 43 of the anode plate assembly, forming a dense grid-like obstacle. If the cleaning roller 22 and the drive head 21 are rigidly connected as a whole, the movement of the entire cleaning device 2 in the Y direction (electrode plate arrangement direction) will be severely blocked by these cross beams, making it impossible to move directly to the next adjacent cleaning position. This invention, by designing the cleaning roller 22 to be quickly detached and installed from the drive head 21, decomposes the large cleaning device 2 into two parts in the bottom area: the upper part is the drive head 21 and the hoisting device 1, and the lower part is the cleaning roller 22.

[0039] At this time, the drive head 21 is lifted by the hoisting equipment 1 and moved from the open area above the electrode assembly 4 (above the upper frame 443). This area is spacious and unobstructed by the lower crossbeams, allowing it to easily traverse the entire electrode assembly 4 and hover directly above the next electrode 41 to be cleaned.

[0040] After the cleaning roller 22 is disassembled, it falls directly into the receiving cylinder 32 located below the lower frame 441 and above the ash hopper. The receiving cylinder 32 not only receives the cleaning roller 22 but also plays a role in precise positioning. When the cleaning roller 22 slides to the designated position on the slide rail 31, its central axis is aligned with the centering position of the next electrode plate 41 to be cleaned. At this time, the mechanical slide rail 31 and receiving cylinder 32 transfer the cleaning roller 22, avoiding deformation or damage that may be caused by the cleaning roller 22 being placed randomly or dragged at the bottom. At the same time, it also prevents collision damage to the cleaning equipment 2 or the electrode plate frame itself when attempting to forcibly cross the bottom crossbeam 432. When the drive head 21 descends, it can easily and quickly and accurately dock with the cleaning roller 22, avoiding errors that may be caused by manual positioning. This space is located further below the lower frame 441 of the cathode wire assembly, so it is completely unaffected by structures such as the cathode lower crossbeam 4412. The cleaning roller 22 slides on the bottom slide rail 31, moving in an unobstructed plane.

[0041] After the hoisting equipment 1, drive head 21, receiving cylinder 32, and cleaning roller 22 have all moved to the position of the next electrode plate 41 to be cleaned, they are reorganized to achieve the cleaning of the next electrode plate 41. By solving the obstruction problem, the system can achieve sequential cleaning of multiple electrode plates. This reduces the need for personnel to enter the electrostatic precipitator for heavy and dangerous handling and positioning work. It significantly reduces labor intensity and safety risks, and shortens the cleaning interval of individual electrode plates.

[0042] 3. The hoisting equipment 1 is installed on the top frame 42, and the drive head 21 synchronously drives the cleaning roller 22 to avoid tilting or collision during the cleaning process. The bottom switching equipment 3 is installed below the bottom frame 43, and the receiving cylinder 32 reliably supports the cleaning roller 22 to prevent the equipment from falling or being damaged, thus improving operational safety.

[0043] In one embodiment, the hoisting device 1 is detachably mounted on the top frame 42 of the electrode assembly 4; The bottom switching device 3 is detachably mounted on the bottom frame 43 of the electrode assembly 4.

[0044] In this embodiment, the cleaning system is designed as a modular unit, which can be temporarily installed on existing electrostatic precipitators as an independent mobile cleaning device. Given that the plate cleaning cycle can last for several months, a single system can be deployed in rotation between different electrostatic precipitators, achieving multi-purpose use and significantly improving equipment utilization and return on investment.

[0045] In one embodiment, the hoisting equipment 1 includes a frame 11 and a double-rope winch 12 disposed in the middle of the frame 11. The frame 11 is disposed on the top frame 42 of the pole plate assembly 4. One of the ropes of the double-rope winch 12 passes around one end of the frame 11 and is connected to one of the drive heads 21, and the other rope passes around the other end of the frame 11 and is connected to the other drive head 21.

[0046] In this embodiment, the dual-rope winch 12, acting as a single power source, ensures that the winding and unwinding speeds of the two ropes are strictly synchronized. This allows the two drive heads 21 and the cleaning rollers 22 below them to always remain horizontal and move up and down synchronously, avoiding problems such as equipment jamming, uneven cleaning, or tilting of the electrode plates due to asynchronous lifting, thus ensuring a smooth and safe cleaning process. Compared to using two independent lifting mechanisms, this greatly simplifies the structure, saves costs and installation space, improves transmission efficiency, and achieves control of the movement of the core cleaning components in the simplest and most reliable way.

[0047] In one embodiment, the frame 11 includes a central fixed frame 111 and telescopic frames 112 hinged to both sides of the central fixed frame 111. The ends of the telescopic frames 112 are detachably engaged with the X-direction ends of the top frame 42 of the electrode assembly 4. Preferably, the ends of the telescopic frames 112 are provided with limiting members 14, which enable the detachable engagement of the electrode assembly 4 and the telescopic frames 112. The double-rope winch 12 is mounted on the intermediate fixed frame 111.

[0048] In this embodiment, the telescopic frames 112 on both sides can be flexibly adjusted in length, and the hinged structure allows for adaptive adjustment at a certain angle in the vertical plane. This enables the frame 11 to easily adapt to the top frame 42 of the electrode assembly 4 of different sizes or with certain installation errors, ensuring that both ends can be stably installed. The telescopic and hinged characteristics allow the operator to first roughly position the middle fixed frame 111, and then easily fit the ends of the telescopic frames 112 on both sides with the brackets at the X-direction ends, greatly reducing the difficulty and time of installation and positioning.

[0049] In addition, the telescopic frames 112 on both sides can be folded and retracted. This modular design allows the entire hoisting equipment 1 to be quickly disassembled into compact components, facilitating transfer and transportation between different electrostatic precipitators.

[0050] In one embodiment, the hoisting equipment 1 further includes a positioning detection device 13; The positioning detection device 13 includes a detection device 131 disposed at the end of the frame 11 and a trigger disc 132 disposed at the end of the rope of the double rope winch 12. The detection device 131 includes a fixed frame 1311, a fixed pulley 1312 disposed on the fixed frame 1311, a trigger ring 1313 hinged to the fixed frame 1311, and a trigger rod 1314 disposed on one side of the trigger ring 1313. The trigger rod 1314 is connected to a trigger sensor. The rope of the dual-rope winch 12 passes through the trigger ring 1313. After the trigger disc 132 contacts the trigger ring 1313, the trigger ring 1313 drives the trigger rod 1314 to move, activating the trigger sensor.

[0051] In this embodiment, when the drive head 21 of the cleaning device 2 is raised to a preset limit height, the trigger disc 132 at the end of the rope will contact and push the trigger ring 1313. This mechanical action provides a physical stop signal, which directly cuts off the power of the double rope winch 12 or triggers an emergency stop through the sensor, effectively preventing the drive head 21 from colliding with the top frame 42 or the winch itself from being damaged, thus ensuring the safety of the lifting process.

[0052] In a preferred embodiment, the rope end of the dual-rope winch 12 is provided with a rope hook, which is detachably engaged with the drive head 21. At this time, the trigger ring 1313 is slidably disposed on the rope by gravity, and a compression spring 133 is also provided between the lower end of the trigger ring 1313 and the rope hook, so that the trigger ring 1313 has an elastic buffering effect.

[0053] In this embodiment, the detachable engagement of the rope hook and the drive head 21 allows the drive head 21 (and the cleaning roller 22) to be quickly separated from the hoisting equipment 1. This greatly facilitates the transfer of the entire cleaning equipment 2 (hoisting equipment 1 and cleaning equipment 2) from one electrostatic precipitator unit to another. The addition of the compression spring 133 ensures that when the trigger disc 132 contacts the trigger ring 1313, the impact force is first absorbed and buffered by the compression spring 133. This effectively prevents rigid collisions caused by inertia or improper speed control of the dual-rope winch 12, protects the trigger ring 1313, trigger rod 1314 and trigger sensor from damage, and extends the service life of the positioning detection device 13.

[0054] In one embodiment, hooks 311 are provided at both ends of the slide rail 31, and the hooks 311 can be detachably hung on the bottom frame 43 or the lower frame 441 of the electrode assembly 4. In this embodiment, by directly hanging the slide rail 31 on the bottom frame 43 (bottom crossbeam 432) or the lower frame 441 (cathode lower crossbeam 4412), the slide rail 31 can be quickly installed and disassembled without the need for complicated tools or bolt connections, which greatly simplifies the operation process and saves time.

[0055] This utility model also provides a plate cleaning device 2, which can be used to clean the electrode plates 41 to be cleaned, such as the anode plate 411 or cathode wire 412 of the electrode plate assembly 4, and can also be used to clean other plates. The plate cleaning device 2 includes two drive heads 21 and two cleaning rollers 22.

[0056] The drive head 21 is provided with a rotary drive mechanism 211, which includes an output drive wheel 2111. The drive head 21 is also provided with two mounting clamps 212 that rotate around the axis of the output drive wheel 2111. The cleaning roller 22 includes a mounting clamp 221, a cleaning roller body 222, and a driven wheel 223. The driven wheel 223 and the roller shaft 2221 of the cleaning roller body 222 are rotatably mounted on the mounting clamp 221, and the driven wheel 223 is fixedly connected to the roller shaft 2221 of the cleaning roller body 222. The mounting clamp 221 is detachably mounted on the mounting clamp 212. After the mounting clamp 221 is engaged with the mounting clamp 212, the driven wheel 223 engages with the output drive wheel 2111. The drive head 21 is also provided with an angle adjustment mechanism 213 for adjusting the relative angle of the two mounting clamps 212.

[0057] Among them, the output drive wheel 2111 and the driven wheel 223 are preferably gears.

[0058] The cleaning device 2 provided by this utility model has the following beneficial effects: First, the output drive wheel 2111 directly meshes with the driven wheel 223 on the cleaning roller 22, forming a rigid, slip-free transmission. This transmission method is highly efficient, ensuring that the cleaning roller 22 receives sufficient and stable torque, providing a powerful scrubbing effect.

[0059] Second, the single rotary drive mechanism 211 drives two mounting clamps 212 simultaneously through an output drive wheel 2111, ensuring that the two cleaning rollers 22 can rotate in opposite directions in strict synchronization. This is crucial for the balanced force on both sides when clamping and washing a single electrode plate, and can effectively prevent the electrode plate from deforming due to uneven force.

[0060] Third, the cleaning roller 22 achieves true modularity by quickly engaging and disengaging with the mounting clamp 212 on the drive head 21 via the mounting clamp 221. This makes the replacement, maintenance, and transfer of the cleaning roller 22 on the bottom switching device 3 extremely convenient.

[0061] In addition, when a cleaning roller 22 needs maintenance or replacement, it can be removed independently without touching the entire drive unit, which greatly reduces maintenance time and cost.

[0062] IV. The angle adjustment mechanism 213 allows the relative angle of the two mounting clamps 212 to be adjusted within a certain range, enabling switching between different cleaning states (e.g., switching between state one and state two mentioned above). Furthermore, in state one, this allows the pair of cleaning rollers 22 to adaptively conform to the surfaces of two non-perfectly parallel electrode plates (due to manufacturing or installation errors or deformation during long-term use). This adaptive capability ensures that the bristles or cleaning surface of the cleaning roller body 222 maintains uniform and sufficient contact pressure with the electrode plates along their entire length, avoiding cleaning dead zones or uneven pressure caused by angle mismatch, thereby significantly improving cleaning quality and effectiveness. Additionally, it also prevents insufficient or no contact with the cleaning surface due to wear of the bristles and brush blades.

[0063] Fifth, this design is not only specifically designed for the anode plate 411 or cathode wire 412 of electrostatic precipitators, but its flexible clamping and driving method also makes it applicable to cleaning other similar plate-shaped structures, thus expanding the application range of the equipment.

[0064] In one embodiment, the mounting chuck 212 includes a housing 2121 and a rotating part 2122 connected to each other. The housing 2121 is provided with a cavity 21212 having an opening 21211 at one end. The housing 2121 is provided with a locking structure 21213. The rotating part 2122 is rotatably connected to the driving head 21. The mounting clamp 221 can be detachably engaged into the cavity 21212 through the opening 21211, and the mounting clamp 221 is provided with an engagement structure 2211 that cooperates with the engagement structure 21213.

[0065] Among them, the locking structure 21213 and the locking mating structure 2211 can be structures such as locking blocks and slots, pins and holes, threads and bolts.

[0066] In this embodiment, the mounting clamp 221 is initially positioned by inserting it into the cavity 21212 through the opening 21211 in a specific direction. Subsequently, the engaging structure 21213 and the engaging engagement structure 2211 quickly lock together. The entire process is tool-free and can be completed within seconds, greatly improving the efficiency of switching and maintaining the cleaning roller 22. The cavity 21212 provides all-around constraint on the inserted mounting clamp 221, ensuring precise alignment of the axial and radial positions between the driven wheel 223 on the cleaning roller 22 and the output drive wheel 2111 on the drive head 21.

[0067] In one embodiment, a positioning shaft 214 is provided inside the drive head 21; One of the rotating parts 2122 is a hollow cylindrical structure 21221 with closed ends. The two ends of the cylindrical structure 21221 are rotatably engaged with the positioning shaft 214. The output drive wheel 2111 is disposed inside the cylindrical structure 21221. One side of the cylindrical wall of the cylindrical structure 21221 is connected to the cavity 21212, and the other side is provided with an arc-shaped groove 212211 that exposes the output drive wheel 2111. Another rotating part 2122 consists of two rotating mounting plates 21222, which are disposed at both ends of the cylindrical structure 21221 and are rotatably engaged with the positioning shaft 214. The arc-shaped groove 212211 connects to the cavity 21212 of the rotating part 2122.

[0068] In this embodiment, the positioning shaft 214 provides a common, fixed, rigid rotation axis for the two rotating parts 2122. This allows the two mounting chucks 212 and their cleaning rollers 22 to rotate around the same axis, ensuring the rotational synchronization accuracy of the two cleaning rollers 22, eliminating minor asynchrony that may occur due to separate support, and ensuring balanced cleaning force. The output drive wheel 2111 is built into the cylindrical structure 21221. This integrated layout is compact, reduces the number of external parts, and improves structural rigidity. The cylindrical structure 21221 partially isolates the core transmission component (output drive wheel 2111) from the external environment, with transmission only achieved through the exposed teeth via necessary arc-shaped grooves 212211. This effectively prevents a large amount of dust and foreign matter inside the electrostatic precipitator from directly intruding into the gear meshing area, greatly reducing the risk of jamming and wear rate, and improving the reliability and service life of the transmission system.

[0069] In one embodiment, a guide structure 212121 is provided inside the cavity 21212, and a guide mating structure 2212 is provided on the side wall of the mounting block 221. The mounting block 221 is fitted into the cavity 21212 through a sliding fit between the guide mating structure 2212 and the guide structure 212121. The guide structure 212121 and the guide mating structure 2212 can be a groove and a slider, respectively.

[0070] Preferably, the mounting clamp 221 also has a receiving cavity 2213. In this case, the driven wheel 223 is set on the receiving cavity 2213, and the side wall of the receiving cavity 2213 is provided with a through groove 2214 for the driven wheel 223 to be exposed, thereby realizing the relatively sealed installation of the driven wheel 223 and improving its environmental adaptability.

[0071] In this embodiment, the insertion of the guide structure 212121 and the guide mating structure 2212 provides clear path guidance. Operators do not need to precisely visually align them; they only need to align the guide structure 212121 with the guide mating structure 2212 for natural positioning, greatly simplifying the operation.

[0072] In one embodiment, the rotary drive mechanism 211 of at least one drive head 21 includes a rotary drive element 2113 and a bevel gear set 2112, wherein the rotary drive element 2113 is disposed on the drive head 21 perpendicular to the cleaning roller 22. The bevel gear set 2112 connects the output drive wheel 2111 and the rotary drive component 2113.

[0073] In this embodiment, only one drive head 21 may be equipped with a rotary drive element 2113 and a bevel gear set 2112. In this case, the other drive head 21 may only have an output drive wheel 2111, which is used as a driven wheel. Alternatively, both drive heads 21 may be equipped with rotary drive elements 2113 and bevel gear sets 2112. In this case, there are two sets of rotary drive elements 2113, which can ensure rotational power.

[0074] In this embodiment, the rotary drive component 2113 (such as a motor) is arranged perpendicular to the cleaning roller 22, and the power transmission direction is changed by using a bevel gear set 2112, which greatly reduces the overall length of the drive head 21 in the axial direction of the cleaning roller 22 (i.e., the direction of the electrode gap). This layout allows the drive head 21 to be made slimmer, making it easier to move and position between space-constrained electrodes, effectively avoiding interference with adjacent electrodes or support structures, and improving the system's passability and adaptability.

[0075] In one embodiment, the angle adjustment mechanism 213 includes a tension spring 2131; Two sets of tension springs 2131 are used to drive the two sets of mounting clamps 212 to move closer together at a small angle or further apart at a large angle. The two sets of mounting clamps 212 moving closer together at a small angle is the clamping state, suitable for state one of the cleaning methods. Driving the two sets of mounting clamps 212 further apart at a large angle is the side-to-side cleaning state, suitable for state two of the cleaning methods.

[0076] In the clamped state, the tension spring 2131 continuously applies an elastic force that brings the two mounting clamps 212 closer together. This force drives the two cleaning rollers 22 to automatically adhere to both sides of the electrode plate 41 to be cleaned. When the electrode plate is uneven or there are installation errors, the tension spring 2131 allows the mounting clamps 212 to produce a slight angle compensation, ensuring that the cleaning rollers 22 make full-area contact with the plate surface and that the pressure is uniform and stable, avoiding excessive local pressure or cleaning dead zones. If there are abnormal protrusions on the electrode plate or the cleaning rollers 22 are stuck, the tension spring 2131 can be stretched to provide cushioning, preventing equipment damage caused by rigid drive (such as motor overload, gear breakage, etc.), thus improving the reliability of the system.

[0077] Both cleaning states (large angles) can achieve a stable force balance point. This means that without external intervention, the cleaning device 2 can stably maintain these two preset working states without unexpected switching due to vibration or other reasons, ensuring the certainty of the cleaning process.

[0078] In one embodiment, the angle adjustment mechanism 213 includes an upper positioning pin 2132 and a lower positioning pin 2133 disposed on the housing of the drive head 21, and an arc-shaped slide groove 2134 disposed on the housing of the drive head 21. The mounting clamp 212 is provided with a tension spring connecting pin 2123 that slides along the arc-shaped slide groove 2134; Two tension springs 2131 are provided. One end of one tension spring 2131 is connected to a tension spring connecting pin 2123 of a mounting clamp 212, and the other end is connected to an upper positioning pin 2132 or a lower positioning pin 2133. One end of the other tension spring 2131 is connected to a tension spring connecting pin 2123 of another mounting clamp 212, and the other end is connected to an upper positioning pin 2132 or a lower positioning pin 2133.

[0079] When the upper positioning pin 2132 is connected, the system is in a cleaning state on both sides. When the lower positioning pin 2133 is connected, the system is in a clamping state.

[0080] In this embodiment, the upper positioning pin 2132 and the lower positioning pin 2133 precisely correspond to the two preset working positions: the cleaning state and the clamping state. The operator can actively and explicitly set and switch the working mode of the cleaning device 2 by selecting to connect the tension spring 2131 to different positioning pins. In each state, the tension of the tension spring 2131 and the mounting clamp 212 reach a stable force balance point within the arc-shaped slide groove 2134 via the tension spring connecting pin 2123. This allows the state to be firmly locked, effectively resisting vibrations and resistance generated during the cleaning process, preventing unexpected changes in the working angle, and ensuring the stability and reliability of the cleaning process.

[0081] In one embodiment, the drive head 21 is further provided with a guide wheel assembly 215 on the side facing the cleaning roller 22, which is used to engage the plate to be cleaned (the electrode plate 41 to be cleaned). When applied to cleaning the electrode plate assembly 4, the guide wheel assembly 215 is used to clamp the anode plate 411. This ensures that the gap between the two cleaning rollers 22 and the two sides of the electrode plate is constant, thereby ensuring uniform brushing pressure and avoiding uneven pressure or cleaning dead zones caused by equipment shaking. It also ensures the stability of movement in both the cleaning and clamping states.

[0082] In one embodiment, the cleaning roller body 222 includes a roller shaft 2221 and a plurality of brush bodies 2222 disposed on the roller shaft 2221; The brush body 2222 includes circumferentially distributed plates 22221 and bristles 22222, with the plates 22221 and bristles 22222 of adjacent sets of brush bodies 2222 arranged alternately. In this embodiment, when the alternately arranged plates 22221 and bristles 22222 rotate, they create a staggered, combined beating and sweeping effect on the electrode surface. This dynamic effect not only helps to loosen firmly adhered dust but also effectively removes the brushed-off dust from the electrode surface and the gap between the brush body 2222, preventing dust accumulation inside the brush body 2222 and reducing the risk of secondary pollution.

[0083] Preferably, several sets of brush bodies 2222 are detachably connected, thereby facilitating the assembly and disassembly of the cleaning roller body 222.

[0084] In one embodiment, the cleaning device 2 is applicable to an electrostatic precipitator cleaning robot, as detailed above, and will not be repeated here.

[0085] The above description is merely an embodiment and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations, modifications, or alterations to the technical solution of this utility model without departing from its scope. Therefore, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model, without departing from its scope, should fall within the protection scope of this utility model.
