Description

Technical Field

[0001] This invention relates to the field of air preheater auxiliary equipment technology, specifically a cleaning device for a visual camera used to block ash in an air preheater. Background Technology

[0002] The air preheater ash blockage visualization camera is used to monitor the ash blockage inside the air preheater in real time. It provides operators with intuitive visual images to facilitate timely detection and handling of ash blockage problems. Because the preheater ash blockage visualization camera operates in a harsh environment of high temperature and high dust for extended periods, dust accumulation on the lens easily affects image quality. Therefore, lens cleaning is necessary. Currently, most self-cleaning air purification cameras integrate a positive pressure air curtain in their core module, which is only effective against light pollutants such as floating dust. For stubborn deposits such as oil stains, high-temperature condensed dust clumps, or insect carcasses, the airflow is insufficient to completely remove them. Furthermore, if the airflow contains... The lens contains a lot of dust, and turbulent airflow may actually exacerbate the adsorption of dust on the lens surface, failing to achieve the desired cleaning effect. Furthermore, the cleaning effect depends on precise airflow control. When the airflow is insufficient, it is difficult to form a complete positive pressure protection zone, and areas such as the lens edge are prone to becoming cleaning blind spots. When the airflow is too large, it will produce the Venturi effect, creating local negative pressure, which will actively adsorb surrounding pollutants, resulting in the opposite of the cleaning effect. Therefore, it cannot completely replace manual cleaning, and the automation effect is not ideal. In view of this, we propose a cleaning device for visual cameras that are clogged with dust in air preheaters to solve the above-mentioned technical problems. Summary of the Invention

[0006] As a preferred embodiment of the present invention, the protective component includes a sheet metal bending support fixedly installed on the top of the Z-shaped base. The sheet metal bending support is located between the platform and the sweeping motor.

Two station plates are fixedly installed on the side of each L-shaped guide block near the sweeping motor. The two station plates are arranged opposite each other, and a rubber waterproof sleeve is fixedly installed on the side of each station plate near the sweeping motor.

[0007] As a preferred embodiment of the present invention, a sealing block is fixedly installed on the side of the rubber waterproof sleeve away from the station plate. The brush disc is located inside the sealing block, and the brush disc and the sealing block are rotatably connected by a sealed bearing. The sealing block is fixed to the side of the motor bracket away from the sweeping motor by a fixing angle bracket. A drain nozzle is integrally formed at the bottom of the rubber waterproof sleeve for draining sewage. A spray pipe is fixedly installed on the upper part of the side of the sealing block near the sweeping motor. The spray pipe penetrates the sealing block and extends into the rubber waterproof sleeve. A cleaning pump is fixedly installed inside the U-shaped base. The output end of the cleaning pump is connected to the input end of the spray pipe through a pipe. A liquid storage tank is fixedly installed at the end of the U-shaped base near the sweeping motor. The output end of the liquid storage tank is connected to the input end of the cleaning pump through a pipe.

[0008] As a preferred embodiment of the present invention, a linear guide rail is fixedly provided on the top of the sheet metal bending support. The linear guide rail is perpendicular to the linear cylinder. Two linear sliders are slidably arranged around the linear guide rail. The tops of the two linear sliders are respectively fastened to the bottoms of the two L-shaped guide blocks by bolts.

[0009] As a preferred embodiment of the present invention, each of the L-shaped guide blocks is rotatably provided with a guide wheel, and a pressing plate is fixedly provided on the side of the platform near the sweeping motor. The side of the pressing plate near the guide wheel has two opposing wedge grooves, and the positions of the wedge grooves correspond one-to-one with the positions of the guide wheels.

[0010] As a preferred embodiment of the present invention, spring positioning rod one is fixedly provided at both ends of the top of the sheet metal bending support, and spring positioning rod two is fixedly provided at the bottom end of the L-shaped guide block away from spring positioning rod one. Spring positioning rod two is located between the two spring positioning rod one, and a tension spring is fixedly provided between spring positioning rod two and spring positioning rod one.

[0011] As a preferred embodiment of the present invention, the U-shaped base includes a positioning disk fixed to the outer wall of the vertical shaft. The positioning disk is located between the platform and the gear. The top of the positioning disk has six guide grooves at equal angles. A top spring is fixedly installed inside each guide groove. A positioning ball is fixedly installed on the top of the top spring. The outer wall of the positioning ball is slidably connected to the inner wall of the guide groove. A pressure cap for limiting the positioning ball is fixedly installed on the top of the positioning disk. Six anti-slip holes are opened through the top of the pressure cap at equal angles. The positions of the anti-slip holes correspond one-to-one with the positions of the guide grooves, and the diameter of the anti-slip holes is smaller than the diameter of the guide grooves.

[0012] As a preferred embodiment of the present invention, the bottom of the platform is provided with six limiting ball grooves at equal angles, and the outer wall of the top of the positioning ball abuts against the inner wall of the limiting ball groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention uses a linear cylinder to retract its output axis into the cylinder, moving the platform towards the cleaning motor. This, in turn, moves the visual camera for air preheater ash blockage, back into the cleaning equipment. The gear meshes with the rack, causing the gear to roll along the rack's tooth surface. This rotation drives the vertical shaft and the visual camera to rotate towards the brush plate. Upon contact with the brush plate, the cleaning motor's output shaft drives the brush plate to rotate, cleaning the camera lens. Simultaneously, a cleaning pump sprays cleaning fluid stored in the storage tank onto the brush plate surface through a spray pipe. This, combined with the rotating wiping effect of the brush plate, thoroughly cleans the camera lens, thus completing the fully automated cleaning of the air preheater ash blockage visual camera.

[0014] 2. During the movement of the platform towards the sweeping motor, the extrusion plate also moves along with it. Eventually, the wedge surfaces in the two wedge grooves contact the outer walls of the two guide wheels respectively. After contact, as the platform continues to move the extrusion plate, the wedge force between the wedge surfaces in the wedge grooves and the guide wheels causes the two L-shaped guide blocks to move towards the center. The movement of the L-shaped guide blocks is kept stable by the sliding guidance of the linear slider and the linear guide rail. At the same time, the movement of the two L-shaped guide blocks also causes the two spring positioning rods to move together, resulting in the two tension springs being stretched and storing force. Furthermore, the opposing movement of the two L-shaped guide blocks also causes the two station plates to move together, bringing the opening of the rubber waterproof sleeve towards the center. This ensures that the opening of the rubber waterproof sleeve covers the periphery of the visual camera lens for ash blocking in the air preheater. This ensures that the cleaning fluid sprayed by the spray pipe is discharged to the outside through the connection between the drain nozzle and the external pipe, preventing the cleaning fluid from contaminating the internal components of the sweeping equipment.

[0015] 3. In this invention, the positioning slider, under the elastic force of the top spring, causes its top outer wall to abut against the inner wall of the limiting ball groove. This mutual abutment between the positioning slider and the limiting ball groove provides a vertical axis angle limiting effect, preventing unnecessary rotation of the vertical axis and the air preheater ash-blocking visualization camera fixed on its top. After the gear and rack mesh, as the gear rolls along the rack tooth surface and drives the vertical axis to rotate, the vertical axis drives the positioning disk, top spring, positioning slider, and pressure cover to rotate together. At this time, the positioning slider is squeezed downward by the limiting ball groove and continues to compress the top spring, thus not interfering with the normal rotation of the vertical axis, so that the lens of the air preheater ash-blocking visualization camera can rotate towards the brush disk.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-12 The technical solution provided by the present invention specifically includes the following embodiments: A cleaning device for a visual camera used for air preheater ash blockage includes a U-shaped base 100, a platform 200 slidably mounted on top of the U-shaped base 100 along its length, two parallel linear guide rails 1100 fixedly mounted on top of the U-shaped base 100, two linear sliders 1200 slidably mounted around each of the two linear guide rails 1100, the tops of the linear sliders 1200 being fastened to the bottom of the platform 200 by bolts, and a cleaning motor 600 fixedly mounted on top of the U-shaped base 100. The platform 200 has a shaft hole 201 on its top, and a vertical shaft 300 is rotatably mounted inside the shaft hole 201. The visual camera for air preheater ash blockage is fixedly mounted on top of the vertical shaft 300. A gear 400 is fixedly installed at the bottom of the 100. A rack 500 is fixedly installed on the inner side of the bottom of the 100. An angle positioning component 1000 is fixedly installed on the periphery of the vertical shaft 300 for angular positioning of the vertical shaft 300. A motor bracket 601 for fixing the cleaning motor 600 is fixedly installed at the top of the 100. The cleaning motor 600 is fixedly installed on the side of the motor bracket 601 by bolts. A brush 700 for cleaning the visual camera for air preheater ash blockage is fixedly installed on the output shaft of the cleaning motor 600. A linear cylinder 800 for driving the platform 200 to move is fixedly installed inside the 100. A protective component 900 for protecting the visual camera for air preheater ash blockage is fixedly installed at the top of the 100. The rack 500 is compatible with the gear 400, and the rack 500 is positioned to correspond to the gear 400. The length of the rack 500 is half the circumference of the gear 400. The output rod end of the linear cylinder 800 is fixedly connected to the platform 200 via a floating joint. The sweeping motor 600 is located on the side of the motor bracket 601 away from the platform 200, and is coaxial with the air preheater dust blocking visualization camera fixedly installed on the top of the vertical shaft 300.

[0020] Specifically, the linear cylinder 800 retracts axially, causing the platform 200 to move towards the sweeping motor 600. The platform 200 is stabilized by the sliding guidance of the linear guide rail 1100 and the linear slider 1200. The movement of the platform 200 also moves the vertical shaft 300, along with the air preheater dust-clogging visualization camera, gear 400, and angle positioning component 1000 fixed to the top of the vertical shaft 300, retracting the air preheater dust-clogging visualization camera into the sweeping equipment. After it has completely retreated into the cleaning equipment, the output rod of the linear cylinder 800 continues to drive the platform 200 to move, causing the gear 400 to mesh with the rack 500. Then, as the platform 200 continues to move, the gear 400 rolls along the tooth surface of the rack 500, driving the vertical shaft 300 and the air preheater ash-blocking visualization camera to rotate. It should be noted that the length of the rack 500 is only half the circumference of the gear 400; therefore, after the gear 400 meshes with the rack 500, the gear 400 only… The vertical shaft 300 and the visual camera for air preheater ash blockage can rotate half a turn along the tooth surface of the rack 500. This means that the camera lens can also rotate half a turn, turning it towards the brush plate 700. After the camera lens is facing the brush plate 700, the output rod of the linear cylinder 800 continues to drive the platform 200 to move, causing the vertical shaft 300 to continue to move the camera towards the brush plate 700 until the camera lens contacts the surface of the brush plate 700. The output shaft of the cleaning motor 600 drives the brush plate 700 to rotate, cleaning the camera lens. At the same time, the cleaning pump 603 sprays the cleaning fluid stored in the storage tank 604 onto the surface of the brush plate 700 through the spray pipe 602. Combined with the wiping effect of the rotating brush plate 700, the camera lens is cleaned. This completes the fully automated cleaning of the camera.

[0021] For further details, please refer to [link / reference]. Figures 5-10 As shown: The protective component 900 includes a sheet metal bending support 901 fixedly installed on the top of the Z-shaped base 100. The sheet metal bending support 901 is located between the platform 200 and the sweeping motor 600. Two L-shaped guide blocks 902 are slidably arranged opposite each other on the top of the sheet metal bending support 901. A linear guide rail 906 is fixedly installed on the top of the sheet metal bending support 901. The linear guide rail 906 is perpendicular to the linear cylinder 800. Two linear sliders 907 are slidably arranged around the linear guide rail 906. The tops of the two linear sliders 907 are respectively fastened to the bottoms of the two L-shaped guide blocks 902 by bolts. Two station plates 903 are fixedly installed on the side of the two L-shaped guide blocks 902 near the sweeping motor 600. The two station plates 903 are arranged opposite each other, and a rubber waterproof sleeve 904 is fixedly installed on the side of the two station plates 903 near the sweeping motor 600. The rubber waterproof sleeve 904 is located around the brush disc 700. A sealing block 905 is fixedly installed on the side of the rubber waterproof sleeve 904 away from the station plate 903. The brush disc 700 is located inside the sealing block 905, and the brush disc 700 and the sealing block 905 are rotatably connected by a sealed bearing. The sealing block 905 is fixed to the side of the motor bracket 601 away from the sweeping motor 600 by a fixing angle bracket. The bottom of the rubber waterproof sleeve 904 is integrally formed with a drain nozzle 9014 for draining sewage. The sealing block 905 is close to the sweeping motor. A spray pipe 602 is fixedly installed on the upper side of one side of the 600. The spray pipe 602 passes through the sealing block 905 and extends into the rubber waterproof sleeve 904. A cleaning pump 603 is fixedly installed inside the Z-shaped base 100. The output end of the cleaning pump 603 is connected to the input end of the spray pipe 602 through a pipe. A liquid storage tank 604 is fixedly installed at the end of the Z-shaped base 100 near the cleaning motor 600. The output end of the liquid storage tank 604 is connected to the input end of the cleaning pump 603 through a pipe. The top of each L-shaped guide block 902 is rotatably equipped with a guide wheel 908. A pressing plate 909 is fixedly installed on the side of the platform 200 near the sweeping motor 600. Two opposing wedge grooves 9010 are opened on the side of the pressing plate 909 near the guide wheel 908, and the positions of the wedge grooves 9010 correspond one-to-one with the positions of the guide wheel 908. Spring positioning rod 1 9011 is fixedly installed at both ends of the top of the sheet metal bending support 901. Spring positioning rod 2 9012 is fixedly installed at the bottom of the L-shaped guide block 902 away from the spring positioning rod 1 9011. The spring positioning rod 2 9012 is located between the two spring positioning rods 1 9011. A tension spring 9013 is fixedly installed between the spring positioning rod 2 9012 and the spring positioning rod 1 9011.

[0022] Specifically, during the movement of the platform 200 toward the sweeping motor 600, it also drives the extrusion plate 909 to move together. Eventually, the wedge surfaces inside the two wedge grooves 9010 contact the outer walls of the two guide wheels 908 respectively. After contact, as the platform 200 continues to drive the extrusion plate 909 to move, the wedge force between the wedge surfaces inside the wedge grooves 9010 and the guide wheels 908 causes the two L-shaped guide blocks 902 to move towards the center in opposite directions. The movement of the L-shaped guide blocks 902 is stabilized by the sliding guidance of the linear slider 907 and the linear guide rail 906. Simultaneously, the two L-shaped guide blocks 902... The movement of the L-shaped guide block 902 also drives the two spring positioning rods 9012 to move together, causing the two tension springs 9013 to be stretched and stored. Furthermore, the opposing movement of the two L-shaped guide blocks 902 also drives the two station plates 903 to move together, bringing the opening of the rubber waterproof sleeve 904 inward and covering the outside of the air preheater ash blocking visualization camera lens. This ensures that the cleaning fluid sprayed by the spray pipe 602 is discharged to the outside through the connection between the drain nozzle 9014 and the external pipe, so as to prevent the cleaning fluid from contaminating the internal components of the cleaning equipment.

[0023] For further details, please refer to [link / reference]. Figure 11 , Figure 12 As shown: The Z-shaped base 100 includes a positioning plate 1001 fixed to the outer wall of the vertical shaft 300. The positioning plate 1001 is located between the platform 200 and the gear 400. Six guide grooves 1002 are equally angled on the top of the positioning plate 1001. A top spring 1003 is fixedly installed inside each guide groove 1002. A positioning ball 1004 is fixedly installed on the top of each top spring 1003. The outer wall of the positioning ball 1004 is slidably connected to the inner wall of the guide groove 1002. A pressure cap 1005 for limiting and positioning the slider 1004 is fixedly installed at the top. The pressure cap 1005 has six anti-slip holes 1006 distributed at equal angles through the top. The positions of the anti-slip holes 1006 correspond one-to-one with the positions of the guide grooves 1002, and the diameter of the anti-slip holes 1006 is smaller than the diameter of the guide grooves 1002. Six limiting ball grooves 1007 are opened at equal angles at the bottom of the platform 200. The outer wall of the top of the positioning slider 1004 abuts against the inner wall of the limiting ball grooves 1007.

[0024] Specifically, under the elastic force of the top spring 1003, the outer wall of the positioning ball 1004 abuts against the inner wall of the limiting ball groove 1007. This mutual abutment between the positioning ball 1004 and the limiting ball groove 1007 provides an angle limiting effect for the vertical shaft 300, preventing unnecessary rotation of the vertical shaft 300 and the air preheater dust-blocking visualization camera fixed on its top. After the gear 400 meshes with the rack 500, as the gear 400 rolls along the tooth surface of the rack 500, driving the vertical shaft 300 to rotate, the vertical shaft 300 drives the positioning disk 1001, the top spring 1003, the positioning ball 1004, and the pressure plate... As the cover 1005 rotates, the positioning ball 1004 is pressed downward by the limiting ball groove 1007, continuing to compress the top spring 1003. This prevents interference with the normal rotation of the vertical shaft 300, allowing the air preheater dust-clogging visualization camera lens to rotate toward the brush plate 700. After the air preheater dust-clogging visualization camera lens rotates toward the brush plate 700, the gear 400 and rack 500 disengage, and the top spring 1003 pushes the positioning ball 1004 to abut against the limiting ball groove 1007, again limiting the angle of the vertical shaft 300, ensuring that the air preheater dust-clogging visualization camera does not rotate during cleaning.

[0025] This solution provides a cleaning device for a visual camera used for air preheater ash blockage. First, the visual camera is fixedly installed at the top of the vertical axis 300. Then, the cleaning device, along with the visual camera, is fixedly installed at the visual installation position for real-time monitoring of air preheater ash blockage. Because the visual camera operates in a harsh environment of high temperature and high dust for extended periods, dust easily accumulates on the lens, affecting image quality. Therefore, once the lens affects the image quality, its surface needs to be cleaned. The specific process is as follows: The output axis of linear cylinder 800 retracts into the cylinder, driving platform 200 to move towards sweeping motor 600. Platform 200 is stabilized by the sliding guidance of linear guide rail 1100 and linear slider 1200. The movement of platform 200 also moves vertical shaft 300, along with the air preheater dust-clogging visualization camera, gear 400, and angle positioning component 1000 fixed to the top of vertical shaft 300. This retracts the air preheater dust-clogging visualization camera into the sweeping equipment. Once fully retracted, the output rod of linear cylinder 800 continues to drive platform 200, causing the gear 400 to move further into the sweeping equipment. Gear 400 meshes with rack 500. Then, as the platform 200 continues to move, gear 400 rolls along the tooth surface of rack 500, driving vertical shaft 300 and air preheater ash blockage visualization camera to rotate. It should be noted that the length of rack 500 is only half the circumference of gear 400. Therefore, after gear 400 meshes with rack 500, gear 400 can only rotate half a turn along the tooth surface of rack 500. In other words, vertical shaft 300 and air preheater ash blockage visualization camera can also rotate half a turn. This allows the lens of air preheater ash blockage visualization camera to be rotated toward brush plate 700. After the visual camera lens of the air preheater is facing the brush plate 700, the output rod of the linear cylinder 800 continues to drive the platform 200 to move, so that the vertical axis 300 continues to drive the visual camera lens of the air preheater to move towards the brush plate 700 until the visual camera lens of the air preheater is in contact with the surface of the brush plate 700. The output shaft of the cleaning motor 600 drives the brush plate 700 to rotate, cleaning the visual camera lens of the air preheater. At the same time, the cleaning pump 603 sprays the cleaning liquid stored in the liquid storage tank 604 through the spray pipe 602 onto the surface of the brush plate 700. Combined with the wiping effect of the rotating brush plate 700, the visual camera lens of the air preheater is cleaned. Furthermore, as the platform 200 moves towards the sweeping motor 600, it also drives the extrusion plate 909 to move together. Eventually, the wedge surfaces inside the two wedge grooves 9010 contact the outer walls of the two guide wheels 908. After contact, as the platform 200 continues to drive the extrusion plate 909, the wedge force between the wedge surfaces inside the wedge grooves 9010 and the guide wheels 908 causes the two L-shaped guide blocks 902 to move towards the center. The movement of the L-shaped guide blocks 902 is stabilized by the sliding guidance of the linear slider 907 and the linear guide rail 906. Simultaneously, the two L-shaped... The movement of guide block 902 also drives the two spring positioning rods 9012 to move together, causing the two tension springs 9013 to be stretched and stored. Furthermore, the opposing movement of the two L-shaped guide blocks 902 also drives the two station plates 903 to move together, bringing the opening of the rubber waterproof sleeve 904 inward and covering the outside of the lens of the air preheater ash blocking visualization camera. This ensures that the cleaning fluid sprayed by the spray pipe 602 is discharged to the outside through the connection between the drain nozzle 9014 and the external pipe, so as to prevent the cleaning fluid from contaminating the internal components of the cleaning equipment.

[0026] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention.
