Description

Technical Field

[0001] This invention belongs to the field of ultrasonic cleaning technology, and particularly relates to an ultrasonic cleaning device and cleaning method for insulating protective equipment. Background Technology

[0002] In live-line work, insulating protective equipment plays a crucial role in protecting workers from electric shock and other hazards. During use, this equipment may become contaminated with dust, oil, and other pollutants. If not cleaned promptly, these contaminants can reduce the insulation performance of the insulating materials, increasing the risk of electric shock and short circuits. Because insulating protective equipment is generally made of soft insulating materials such as rubber, conventional cleaning methods rely on manual operation, resulting in low efficiency and incomplete cleaning. Improper cleaning techniques can also accelerate wear and aging of the equipment. Furthermore, different types of insulating protective equipment come into contact with different contaminants, including dust, oil, and oxides. Conventional cleaning requires manual identification of the contaminant type before adding the appropriate cleaning agent, which is prone to misjudgment and waste due to the use of the wrong agent. Precise control of the dosage is also difficult when manually adding cleaning agents, and prolonged immersion in high-concentration agents can easily damage the surface insulation performance of the equipment. Therefore, designing an ultrasonic cleaning device and method for insulating protective equipment that improves cleaning efficiency and allows for precise cleaning agent concentration has become an urgent technical problem to be solved. Summary of the Invention

[0003] To solve the above problems, the present invention provides an ultrasonic cleaning device and cleaning method for insulating protective equipment.

[0004] The technical solution of the present invention is an ultrasonic cleaning device for insulating protective equipment, comprising a contaminant detection module for insulating protective equipment and an ultrasonic cleaning module.

[0005] The pollutant detection module includes a detection platform, a laser camera module connected above the detection platform, and a central control computer connected to the laser camera module; the central control computer is equipped with a pollutant analysis module and is connected to the ultrasonic cleaning module for operation control.

[0006] The laser camera module projects images onto the testing platform, and insulating protective equipment is placed according to the projection. The laser camera module captures images of the insulating protective equipment and sends them to the central control computer. The analysis module combines image processing and computer vision technology to identify the captured images, compares them with standard images of the insulating protective equipment to analyze the color of the contaminants, and determines the type of insulating protective equipment and contaminants. The ultrasonic cleaning module includes a cleaning sub-module and a cleaning agent mixing module. The cleaning sub-module is equipped with an ultrasonic cleaning tank, a cylinder-driven lifting and lowering mesh clamp, a motor-driven rotating cleaning brush, a spray pipe with nozzles facing the ultrasonic cleaning tank, and a high-pressure blower.

[0007] The cleaning agent mixing module includes several storage tanks arranged in a horizontal direction, each containing several spherical beads. The bottom center has an outlet for a single spherical bead to pass through. Different types of cleaning agents are wrapped in the spherical beads in different storage tanks.

[0008] The baffle is attached to the bottom of the storage tank and covers the outlet. It is connected to a horizontal track for movement and controls the opening and closing of the outlet. The rupture groove is located below the baffle. It has rupture pins with upward-pointing tips inside and a drain port at the bottom to break up spherical beads and allow the cleaning agent to flow out.

[0009] A flushing pump is installed between the baffle and the break groove, and is connected to a water supply pipe that draws in deionized water and a water outlet nozzle facing the break groove.

[0010] The return water tank is located below the break tank to collect the cleaning agent and deionized water flowing down from the drain outlet. It has a slowly rotating stirring mechanism inside and a return water pump and outlet pipe connected to the ultrasonic cleaning tank on the side.

[0011] By moving the baffle horizontally to offset the outlets of different storage tanks, spherical beads containing different cleaning agents pass through the outlets, fall into the break groove, and are broken by the tip of the break nail. The flushing pump is started, and the water nozzle sprays deionized water into the break groove. The deionized water washes away the cleaning agent in the break groove, and falls into the return water tank through the drain. The stirring mechanism rotates to fully mix the cleaning agent and deionized water. The return water pump pumps the mixture from the outlet pipe into the ultrasonic cleaning tank. Then, the cleaning brush and the ultrasonic cleaning tank are set vertically, and the mesh clamp fixes the insulating protective equipment, which moves up and down between the two. It cyclically receives ultrasonic oscillation cleaning from the ultrasonic cleaning tank, brushing from the cleaning brush, and spraying from the spray pipe. The high-pressure blower is set on one side of the ultrasonic cleaning tank, and blows air to dry the insulating protective equipment.

[0012] Using the above method, the contaminant detection module takes photos of the insulating protective equipment at designated locations on the detection platform. Combined with image processing and computer vision technology, the system automatically identifies the type of insulating protective equipment and contaminants. Compared to manual methods, this reduces the probability of misidentifying contaminant types and avoids waste caused by using the wrong cleaning agent. The central control computer determines the storage tank containing the corresponding cleaning agent based on the type of insulating protective equipment and contaminants. It controls the corresponding baffle to be offset from the outlet of the storage tank and resets it after a unit of time. This allows the lowest spherical bead in the storage tank sufficient time to fall from the outlet and enter the rupture groove below. The cleaning agent encapsulates the spherical bead, and the outlet allows individual spherical beads to pass through, enabling more precise control of the amount of cleaning agent used per cycle and preventing the cleaning effect from being affected. Impact: By impacting the upward-pointing break pin, the spherical beads break, allowing the cleaning agent inside to flow down the break pin and then out from the drain port at the bottom of the break groove, falling into the return water tank. The flushing pump then pumps deionized water from the supply pipe, spraying it from the outlet nozzle into the break groove to flush away any remaining cleaning agent, ensuring the cleaning agent completely enters the return water tank. The stirring mechanism slowly rotates, thoroughly mixing the deionized water and cleaning agent to ensure a uniform concentration of the cleaning agent. The return water pump then pumps the mixture from the outlet pipe into the ultrasonic cleaning tank for direct use, improving the efficiency of ultrasonic cleaning. Through ultrasonic oscillation cleaning, brushing, and spraying, the process is highly efficient, fast, and mechanized, minimizing damage to protective equipment and protecting the surface insulation properties of insulating protective gear, thus reducing the risk of electric shock and short circuits during use.

[0013] As a further improvement of the present invention, the insulating protective equipment includes insulating gloves, insulating clothing and insulating blankets, and a soft shielding layer. The amount of deionized water used in a single cleaning is 300L. The cleaning agent includes dish soap, water-based neutral oil stain cleaner, 2-amino-2-ethyl-1-propanol, and ethanol. The cleaning agent corresponding to the insulating gloves is 0.5L of dish soap, the cleaning agent corresponding to the insulating clothing and insulating blanket is 3L of water-based neutral oil stain cleaner, and the cleaning agent corresponding to the soft shielding layer is 1L of 2-amino-2-ethyl-1-propanol and 1L of ethanol. The volume of the spherical beads is 0.25L.

[0014] By using the above method, different ratios of cleaning agents and deionized water can be used to remove different contaminants from different insulating protective equipment with maximum efficiency.

[0015] As a further improvement of the present invention, the top of the storage tank is provided with a drive motor, and the drive motor shaft is connected to a structural adjustment mechanism for linkage. The structural adjustment mechanism includes a top plate and a bottom plate, and a supporting column is connected between the top plate and the bottom plate. The top plate is provided with an inlet for spherical beads to be placed in, and the bottom plate is provided with a through hole corresponding to the outlet. The bottom plate is also provided with several upward-curving scrapers, which are spaced apart along the circumferential direction of the through hole.

[0016] After adopting the above method, the drive motor is started by the central control computer, which drives the structural adjustment mechanism to rotate. The scraper on the bottom plate pushes the spherical beads at the bottom of the storage tank to move, and opens the through hole to the outlet. This allows the spherical beads to be arranged above the through hole during the movement, avoiding the spherical beads from squeezing each other and falling out of the outlet. The inlet is set in the top plate, which can replenish the storage tank with spherical beads. The part of the top plate is blocked, which can reduce the spherical beads at the top from falling out of the inlet when the scraper pushes the spherical beads.

[0017] As a further improvement of the present invention, the top end of the scraper is connected to a downwardly recessed arc-shaped plate, the axial direction of the arc-shaped plate is opposite to the radial direction of the through hole, and the depth of the arc-shaped plate is greater at one end near the through hole than at the other end.

[0018] Using the above method, when the storage tank only has spherical beads on the side wall away from the outlet, the spherical beads lack the pressure of the other spherical beads above them. Driven by the scraper, they roll along the scraper to the top and enter the arc plate. Since the depth of the arc plate is greater at the end near the through hole than at the other end, the spherical beads are rolled towards the deeper end of the arc plate under the action of gravity and fall to the location of the through hole, so that all the spherical beads in the storage tank can fall out from the outlet.

[0019] As a further improvement of the present invention, the baffle is provided with an upward extension plate, the extension plate is connected to a rotary motor, and the rotary motor shaft is connected to a drive wheel; the side of the storage tank is provided with a horizontal track, and the drive wheel is connected to the horizontal track to rotate.

[0020] After adopting the above method, the drive wheel is driven to rotate by the rotary motor, and moves on the horizontal track, causing the baffle to move horizontally and be offset from or reset to the outlet.

[0021] As a further improvement of the present invention, the horizontal track is parallel to the arrangement direction of the storage tank. The baffle is equipped with a turntable motor, a feeding turntable, and a feeding port. The feeding port is located in the middle of the baffle. The feeding turntable is provided with a blocking area and a feeding area in sequence along its circumference. The outer side of the feeding turntable is provided with a disc-shaped turntable shell. The feeding area is provided with a plurality of conveying grooves at intervals along its length. The turntable motor is provided with a turntable shaft. The turntable shaft passes through the turntable shell and is axially connected to the feeding turntable. The circumference of the turntable shell is provided with a notch that connects upward to the feeding port. The bottom is provided with a discharge port. The position and size of the feeding port and the conveying groove are matched with the outlet.

[0022] Using the above method, with the horizontal track parallel to the arrangement of the storage tanks, a baffle can block all the outlets. As the baffle moves horizontally, the feed inlet aligns with different outlets for the spherical beads to fall. A turntable motor drives the feeding turntable to rotate. When the blocking area aligns with the feed inlet, the feed inlet is blocked, and the spherical beads cannot fall when the baffle moves horizontally. When spherical beads are needed, the feed inlet moves below the corresponding outlet, and the feeding turntable rotates to move the conveying troughs sequentially to the feed inlet, allowing one spherical bead to fall into each conveying trough. Then, the baffle moves to offset the outlet, and the feeding turntable rotates to align the conveying troughs sequentially with the outlets, allowing the spherical beads to fall into the break-in trough. After obtaining spherical beads from one storage tank, the feeding turntable reverses, the blocking area aligns with the feed inlet again, and the baffle moves to align the feed inlet with the outlet of another storage tank to obtain spherical beads. This allows for the simultaneous use of multiple cleaning agents.

[0023] As a further improvement of the present invention, the spherical beads comprise a polyvinyl alcohol water-soluble film with a degree of hydrolysis higher than 95%, and the cleaning agent is encapsulated within the polyvinyl alcohol thick water-soluble film; the bottom surface of the baffle is provided with a pair of support frames adapted to the position of the break groove, and a pressure block is provided between the support frames; a vertical limiting groove is provided on the side of the support frame facing the pressure block, and a limiting post is provided on the side of the pressure block, the limiting post being inserted into the limiting groove; a bearing platform is provided on the outer edge of the break groove, and a magnetic suction groove is provided on the inner edge; the bearing platform is in contact with the bottom surface of the pressure block; an electromagnet is provided at the bottom of the magnetic suction groove, and the magnetic suction groove is provided with a lifting inclined surface connecting the bearing platform; the bottom surface of the pressure block is also provided with a magnetic suction part corresponding to the position of the electromagnet; an electric heating mechanism is also connected between the flushing pump and the water nozzle.

[0024] Using the above method, the spherical beads, which contain a polyvinyl alcohol water-soluble film with a degree of alcoholysis higher than 95%, are not easily hydrolyzed at room temperature, making them more stable and less prone to breakage when encapsulating cleaning agents. They are also less likely to break at the storage tank and the feeding turntable. After the spherical beads are placed into the breaking groove, the baffle moves horizontally again, and the pressure block is pulled by the pull support frame. The pressure block moves from the support platform to above the breaking groove. When the pressure block is completely misaligned with the support platform, the limiting groove and the limiting post guide the pressure block to slowly slide down the lifting slope and press it onto the spherical beads. The electromagnet is activated to hold the magnetic suction part, and the pressure block presses down further, pressing the spherical beads onto the breaking nail and completely breaking them, preventing some spherical beads from piling up on top and not being able to be broken by the breaking nail. By moving the baffle in the opposite direction, the pressure block is pushed back to its original position when it contacts the lifting slope. After the mixed liquid is sent into the ultrasonic cleaning tank, the electric heating mechanism heats the deionized water, which dissolves the polyvinyl alcohol water-soluble film at high temperature, preventing the drain port from being blocked.

[0025] As a further improvement of the present invention, the lower edge of the pressure block is provided with an arc-shaped contact surface corresponding to the lifting slope, and a support spring is provided between the limiting post and the bottom of the limiting groove. The elastic force of the support spring is less than the weight of the pressure block. The top of the breaking nail is lower than the bottom surface of the magnetic groove and the distance between the two is less than the diameter of the spherical bead.

[0026] After adopting the above method, the lifting slope is contacted by the arc-shaped contact surface, so that the pressure block can be pushed back to its original position more smoothly; a support spring is provided between the limiting post and the bottom of the limiting groove to share the weight of the pressure block, so that the pressure block can be pushed back to its original position more easily; the top of the breaking nail is lower than the bottom surface of the magnetic suction groove and the distance between the two is less than the diameter of the spherical bead, so that the spherical bead is not easy to roll to the side and fall out of the breaking groove.

[0027] As a further improvement of the present invention, a deionized water filter is provided below the return water tank. The deionized water filter is provided with an inlet pipe connected to the ultrasonic cleaning tank, and the outlet of the deionized water filter is connected to a water supply pipe.

[0028] By using the above method, the water used for ultrasonic cleaning is filtered through a deionized water filter to obtain deionized water again, which is then transported from the water supply pipe to the flushing pump, reducing water waste, saving time required for water intake and drainage, and improving cleaning efficiency.

[0029] A cleaning method, the steps of which include:

[0030] S1, wire mesh clamp fixing insulation and protection equipment;

[0031] S2, the cleaning agent mixing module mixes the cleaning agent and pumps it into the ultrasonic cleaning tank;

[0032] S3, ultrasonic oscillation cleaning;

[0033] S4, the mesh clamp rises and leaves the ultrasonic cleaning tank, and the cleaning brush washes away dirt;

[0034] S5, the mesh clamp descends back into the ultrasonic cleaning tank, the cleaning agent is mixed again, and ultrasonic oscillation cleaning is performed.

[0035] S6, the mesh clamp rises and leaves the ultrasonic cleaning tank, and deionized water is sprayed to remove dirt;

[0036] S7, start the high-voltage blower to blow air into the mesh clamp, and use cold air to dry the insulating protective equipment;

[0037] s8, Remove the insulating protective equipment from the mesh clamp.

[0038] After adopting the above method, since the insulating protective equipment is made of soft material, the oscillation effect generated by ultrasound cannot be transmitted to all parts of the insulating protective equipment when it is conventionally stacked. By fixing the insulating protective equipment with a mesh clamp, it is suspended in the ultrasonic cleaning tank, and the oscillation wave vibrates the insulating protective equipment in all directions, achieving a better cleaning effect.

[0047] like Figures 1-4 An ultrasonic cleaning device for insulating protective equipment is shown, comprising a contaminant detection module for the insulating protective equipment and an ultrasonic cleaning module.

[0048] The pollutant detection module includes a detection platform, a laser camera module connected above the detection platform, and a central control computer connected to the laser camera module; the central control computer is equipped with a pollutant analysis module and is connected to the ultrasonic cleaning module for operation control.

[0049] The laser camera module projects images onto the testing platform, and insulating protective equipment is placed according to the projection. The laser camera module captures images of the insulating protective equipment and sends them to the central control computer. The analysis module combines image processing and computer vision technology to identify the captured images, compares them with standard images of the insulating protective equipment to analyze the color of the contaminants, and determines the type of insulating protective equipment and contaminants. The ultrasonic cleaning module includes a cleaning sub-module and a cleaning agent mixing module. The cleaning sub-module is equipped with an ultrasonic cleaning tank, a cylinder-driven lifting and lowering mesh clamp, a motor-driven rotating cleaning brush, a spray pipe with nozzles facing the ultrasonic cleaning tank, and a high-pressure blower.

[0050] The cleaning agent mixing module includes several storage tanks 1 arranged in a horizontal direction, each containing several spherical beads. The bottom center has an outlet 101 for a single spherical bead to pass through. Different types of cleaning agents are wrapped in the spherical beads in different storage tanks 1.

[0051] Baffle 2 is attached to the bottom of storage tank 1 and covers outlet 101. It is connected to a horizontal track for movement to control the opening and closing of outlet 101.

[0052] The rupture groove 3 is located below the baffle 2. It has an upward-pointing rupture nail 301 inside and a drain outlet 302 at the bottom, which is used to break the spherical beads and allow the cleaning agent to flow out.

[0053] The flushing pump 4 is located between the baffle 2 and the break groove 3, and is connected to a water supply pipe 401 that sucks in deionized water and a water outlet nozzle 402 facing the break groove 3.

[0054] The return water tank 5 is located below the break tank 3 and collects the cleaning agent and deionized water flowing down from the drain port 302. It is equipped with a slowly rotating stirring mechanism inside and a return water pump and water outlet pipe connected to the ultrasonic cleaning tank on the side.

[0055] By moving the baffle 2 horizontally to offset the outlets 101 of different storage tanks 1, spherical beads containing different cleaning agents pass through the outlets 101, fall into the break groove 3, and are broken by the tip of the break nail 301. The flushing pump 4 is started, and the water nozzle 402 sprays deionized water into the break groove 3. The deionized water washes the cleaning agent in the break groove 3, and falls into the return water tank 5 through the drain port 302. The stirring mechanism rotates to fully mix the cleaning agent and deionized water. The return water pump pumps the mixture from the water outlet pipe into the ultrasonic cleaning tank. Then, the cleaning brush and the ultrasonic cleaning tank are set vertically, and the mesh clamp fixes the insulating protective equipment, which moves up and down between the two. It cyclically receives ultrasonic oscillation cleaning from the ultrasonic cleaning tank, brushing from the cleaning brush, and spraying from the spray pipe. The high-pressure blower is set on one side of the ultrasonic cleaning tank, and blows air to dry the insulating protective equipment.

[0056] The contaminant detection module takes photos of the insulating protective equipment at designated locations on the detection platform. Combining image processing and computer vision technology, the system automatically identifies the type of contaminant and the type of insulating protective equipment. Compared to manual methods, this reduces the probability of misidentifying contaminant types and avoids waste caused by using the wrong cleaning agent. The central control computer determines the storage tank 1 containing the corresponding cleaning agent based on the type of insulating protective equipment and contaminant. It controls the corresponding baffle 2 to be offset from the outlet 101 of storage tank 1 and resets after a unit of time. This allows the lowest spherical bead in storage tank 1 sufficient time to fall from outlet 101 into the lower slit groove 3, where the cleaning agent encapsulates the spherical bead. The outlet 101 allows individual spherical beads to pass through, enabling more precise control of the amount of cleaning agent used per cycle and preventing the cleaning effect from being affected. The system also uses impact... The upward-pointing break nail 301 breaks the spherical condensate bead, allowing the cleaning agent inside to flow down the break nail 301 and then out through the drain port 302 at the bottom of the break groove 3, falling into the return water tank 5. Then, the flushing pump 4 controls the pumping of deionized water from the water supply pipe 401, which is sprayed from the water outlet nozzle 402 onto the break groove 3 to flush away the cleaning agent remaining in the break groove 3, ensuring that the cleaning agent completely enters the return water tank 5. The stirring mechanism rotates slowly to fully mix the deionized water and cleaning agent, ensuring that the concentration of the cleaning agent is evenly distributed. The return water pump pumps the mixture from the water outlet pipe into the ultrasonic cleaning tank for direct use, improving the efficiency of ultrasonic cleaning. Through ultrasonic oscillation cleaning, brushing, and spraying to remove dirt, the process is highly efficient, fast, and mechanized and automatic, less likely to damage protective equipment, protecting the surface insulation performance of insulating protective equipment, and reducing the risk of electric shock and short circuits during use.

[0057] The insulating protective equipment includes insulating gloves, insulating clothing and insulating blankets, and a soft protective cover layer. The amount of deionized water used in a single cleaning is 300L. The cleaning agent includes dish soap, water-based neutral oil stain cleaner, 2-amino-2-ethyl-1-propanol, and ethanol. The cleaning agent for the insulating gloves is 0.5L of dish soap, the cleaning agent for the insulating clothing and insulating blanket is 3L of water-based neutral oil stain cleaner, and the cleaning agent for the soft protective cover layer is 1L of 2-amino-2-ethyl-1-propanol and 1L of ethanol. The volume of the spherical beads is 0.25L.

[0058] By varying the ratio of different cleaning agents to deionized water, different stains on various insulating protective equipment can be removed with maximum efficiency.

[0059] The storage tank 1 is equipped with a drive motor 102 at the top. The drive motor 102 is shaft-connected to a structural adjustment mechanism for linkage. The structural adjustment mechanism includes a top plate 103 and a bottom plate 104. A support column 105 is connected between the top plate 103 and the bottom plate 104. The top plate 103 is provided with an inlet 106 for spherical beads to be placed in. The bottom plate 104 is provided with a through hole 107 corresponding to the outlet 101. The bottom plate 104 is also provided with several upward-curving scrapers 108. The scrapers 108 are arranged at intervals along the circumferential direction of the through hole 107.

[0060] The central control computer starts the drive motor 102, which drives the structural adjustment mechanism to rotate. The scraper 108 on the bottom plate 104 pushes the spherical beads at the bottom of the storage tank 1 to move, and opens the through hole 107 with the outlet 101. This allows the spherical beads to be arranged above the through hole 107 during the movement, preventing them from squeezing each other and falling out of the outlet 101. The top plate 103 is provided with an inlet 106, which can replenish the storage tank 1 with spherical beads. The part of the top plate 103 is blocked, which can reduce the spherical beads at the top from falling out of the inlet 106 when the scraper 108 pushes the spherical beads.

[0061] The top end of the scraper 108 is connected to a downwardly recessed arc-shaped plate 109. The axial direction of the arc-shaped plate 109 corresponds to the radial direction of the through hole 107. The depth of the arc-shaped plate 109 at one end near the through hole 107 is greater than that at the other end.

[0062] When the storage tank 1 has only spherical beads on the side wall away from the outlet 101, the spherical beads lack the pressure of the other spherical beads above them. Driven by the scraper 108, they roll along the scraper 108 to the top and enter the arc plate 109. As the arc plate 109 is deeper at one end near the through hole 107 than at the other end, the spherical beads are pushed by gravity and roll towards the deeper end of the arc plate 109, falling to the location of the through hole 107, so that all the spherical beads in the storage tank 1 can fall out from the outlet 101.

[0063] The baffle 2 is provided with an upward extension plate 201, the extension plate 201 is connected to a rotary motor 202, and the rotary motor 202 is shaft-connected to a drive wheel 203; the side of the storage tank 1 is provided with a horizontal track 110, and the drive wheel 203 is connected to the horizontal track 110 and rotates.

[0064] The drive wheel 203 is driven to rotate by the rotary motor 202 and moved on the horizontal track 110, which in turn causes the baffle 2 to move horizontally and be offset from or reset to the outlet 101.

[0065] The horizontal track 110 is parallel to the arrangement direction of the storage tank 1. The baffle 2 is equipped with a turntable motor 204, a feeding turntable 205 and a feed inlet 206. The feed inlet 206 is located in the middle of the baffle 2. The feeding turntable 205 is provided with a blocking area 207 and a feeding area along its circumference. The outer side of the feeding turntable 205 is provided with a disc-shaped turntable shell 208. The feeding area is provided with a plurality of conveying grooves 209 at intervals along its length. The turntable motor 204 is provided with a turntable shaft 210. The turntable shaft 210 passes through the turntable shell 208 and is axially connected to the feeding turntable 205. The circumference of the turntable shell 208 is provided with a notch that connects upward to the feed inlet 206, and the bottom is provided with a discharge port. The position and size of the feed inlet 206 and the conveying grooves 209 are matched with the outlet 101.

[0066] With the horizontal track 110 parallel to the arrangement direction of the storage tank 1, a baffle 2 can block all the outlets 101. As the baffle 2 moves horizontally, the inlet 206 aligns with different outlets 101 to allow spherical beads to fall. The turntable motor 204 drives the feeding turntable 205 to rotate. When the blocking area 207 aligns with the inlet 206, the inlet 206 is blocked, and the spherical beads cannot fall when the baffle 2 moves horizontally. When spherical beads are needed, the inlet 206 moves below the corresponding outlet 101, and the feeding turntable 205 rotates to allow the spherical beads to fall. The feeding trough 209 moves sequentially to the inlet 206, and a spherical condensate falls into each feeding trough 209. Then, the baffle 2 moves to be offset from the outlet 101, and the feeding turntable 205 is rotated to align the feeding trough 209 with the outlet in sequence, and the spherical condensate falls into the breaking trough 3. After obtaining the spherical condensate from one storage tank 1, the feeding turntable 205 reverses, and the blocking area 207 is aligned with the inlet 206 again. The baffle 2 moves to align the inlet 206 with the outlet 101 of another storage tank 1 to obtain the spherical condensate. Multiple cleaning agents can be selected and used at the same time.

[0067] The spherical beads comprise a polyvinyl alcohol water-soluble film with a degree of hydrolysis higher than 95%, and the cleaning agent is encapsulated within the thick polyvinyl alcohol water-soluble film. The bottom surface of the baffle 2 is provided with a pair of support frames 211 adapted to the position of the perforation groove 3. A pressure block 212 is provided between the support frames 211. A vertical limiting groove 213 is provided on the side of each support frame 211 facing the pressure block 212. A limiting post 214 is provided on the side of the pressure block 212, and the limiting post 214 is inserted into the limiting groove 213. Inside; the outer edge of the groove 3 is provided with a support platform 303, and the inner edge is provided with a magnetic suction groove 304. The support platform 303 is in contact with the bottom surface of the pressure block 212. The bottom of the magnetic suction groove 304 is provided with an electromagnet 305. The magnetic suction groove 304 is provided with a lifting inclined surface 306 connecting the support platform 303. The bottom surface of the pressure block 212 is also provided with a magnetic suction part corresponding to the position of the electromagnet 305. An electric heating mechanism is also connected between the flushing pump 4 and the water nozzle 402.

[0068] The spherical beads, containing a polyvinyl alcohol water-soluble film with a degree of alcoholysis higher than 95%, are not easily hydrolyzed at room temperature, making them more stable and less prone to breakage when encapsulating cleaning agents. They are also less likely to break at the storage tank 1 and the feeding turntable 205. After the spherical beads are placed into the breaking groove 3, the baffle 2 moves again, and the pressure block 212 is pulled by the pull support frame 211. The pressure block 212 moves from the support platform 303 to above the breaking groove 3. When the pressure block 212 is completely misaligned with the support platform 303, the limiting groove 213 and the limiting post 214 guide the pressure block 212 to... The liquid slowly slides down the lifting ramp 306 and presses onto the spherical beads. The electromagnet 305 is activated to hold the magnetic part, and the pressure block 212 presses down further, pressing the spherical beads onto the breaking nail 301 and breaking them completely, preventing some spherical beads from piling up on top and not being able to be broken by the breaking nail 301. The baffle 2 moves in the opposite direction, and the pressure block 212 contacts the lifting ramp 306 and is pushed back to its original position. After the mixed liquid is sent into the ultrasonic cleaning tank, the electric heating mechanism heats the deionized water, which dissolves the polyvinyl alcohol water film at high temperature, preventing the drain port 302 from being blocked.

[0069] The lower edge of the pressure block 212 is provided with an arc-shaped contact surface 215 corresponding to the lifting inclined surface 306. A support spring 216 is connected between the limiting post 214 and the bottom of the limiting groove 213. The elastic force of the support spring 216 is less than the weight of the pressure block 212. The top of the piercing nail 301 is lower than the bottom surface of the magnetic suction groove 304 and the distance between the two is less than the diameter of the spherical bead.

[0070] The curved contact surface 215 contacts the lifting slope 306, allowing the pressure block 212 to be pushed back to its original position more smoothly; a support spring 216 is provided between the limiting post 214 and the bottom of the limiting groove 213 to share the weight of the pressure block 212, making it easier to push the pressure block 212 back to its original position; the top of the breaking nail 301 is lower than the bottom surface of the magnetic suction groove 304 and the distance between the two is less than the diameter of the spherical bead, making it less likely for the spherical bead to roll to the side and fall out of the breaking groove 3.

[0071] A deionized water filter 501 is provided below the return water tank 5. The deionized water filter is provided with an inlet pipe 502 that connects to the ultrasonic cleaning tank, and the outlet of the deionized water filter is connected to a water supply pipe 401.

[0072] The water used for ultrasonic cleaning is filtered by the deionized water filter 501 to obtain deionized water again, which is then transported from the water supply pipe 401 to the flushing pump 4, reducing water waste, saving time required for water intake and drainage, and improving cleaning efficiency.

[0073] A cleaning method, the steps of which include:

[0074] S1, wire mesh clamp fixing insulation and protection equipment;

[0075] S2, the cleaning agent mixing module mixes the cleaning agent and pumps it into the ultrasonic cleaning tank;

[0076] S3, ultrasonic oscillation cleaning;

[0077] S4, the mesh clamp rises and leaves the ultrasonic cleaning tank, and the cleaning brush washes away dirt;

[0078] S5, the mesh clamp descends back into the ultrasonic cleaning tank, the cleaning agent is mixed again, and ultrasonic oscillation cleaning is performed.

[0079] S6, the mesh clamp rises and leaves the ultrasonic cleaning tank, and deionized water is sprayed to remove dirt;

[0080] S7, start the high-voltage blower to blow air into the mesh clamp, and use cold air to dry the insulating protective equipment;

[0081] s8, Remove the insulating protective equipment from the mesh clamp.

[0082] Because the insulating protective equipment is made of soft material, the oscillation effect generated by ultrasound cannot be transmitted to all parts of the insulating protective equipment when it is conventionally stacked. By fixing the insulating protective equipment with mesh clips, it is suspended in the ultrasonic cleaning tank, and the oscillation wave vibrates the insulating protective equipment in all directions, achieving a better cleaning effect.
