Description

Technical Field

[0001] This utility model relates to the field of ton container equipment technology, specifically to an automatic cleaning and testing device for ton containers. Background Technology

[0002] In industries such as chemical, food, and pharmaceutical, tonnes (ITLs) (including metal and plastic ITLs) are widely used containers for liquid storage and transportation. After the liquid inside an ITL is used up, dirt or residue often accumulates inside. If these residues are not thoroughly removed, they can easily cause cross-contamination of the new liquid being filled, seriously affecting product quality and safety. Therefore, effective cleaning of empty ITLs after use is essential to ensure their safe reuse. Currently, the industry commonly uses two main cleaning methods: manual cleaning and mechanical cleaning. Manual cleaning requires operators to insert cleaning tools deep into the ITL to manually scrub or scrape, which has significant disadvantages such as low efficiency, high labor intensity, and long processing time. Furthermore, due to limitations in the size of the opening and operating space, it is difficult to thoroughly clean stubborn stains on the bottom and corners of the ITL. For more complex metal ITLs, it may even be necessary to cut them open entirely for internal cleaning, followed by re-welding, a cumbersome and costly process. While mechanical cleaning replaces some manual labor with high-pressure water jets that extend into the container, reducing labor intensity, it still struggles to achieve thorough cleaning of all surfaces due to physical limitations in the spray angle and coverage. The cleaning effect is often less than ideal, typically requiring secondary manual cleaning to meet cleanliness requirements. In summary, existing cleaning technologies have significant shortcomings in efficiency, thoroughness, and ease of operation, necessitating the development of more efficient and thorough container cleaning solutions. Utility Model Content

[0003] Technical problem to be solved by the utility model

[0004] The technical problem to be solved by this utility model is to provide an automatic cleaning and testing device for ton containers, which solves the problems of significant deficiencies in efficiency, thoroughness and ease of operation, improves cleaning efficiency and reduces the labor intensity of workers.

[0005] Technical solution

[0006] To solve the above problems, the technical solution provided by this utility model is as follows:

[0007] An automatic cleaning and testing device for ton containers includes a frame, a motion component, a first Y-axis component, and a second Y-axis component. The motion component is horizontally slidably connected to the frame. The first Y-axis component and the second Y-axis component are both vertically slidably connected to the motion component along the Y-axis. The first Y-axis component and the second Y-axis component are respectively provided with a rotatable camera gimbal assembly and a high-pressure cleaning mechanism. The high-pressure cleaning mechanism is also connected to an oil mist collector.

[0008] Frame: Provides rigid support and mounting benchmark for the entire equipment, ensuring stable operation of other moving components and mechanisms.

[0009] Motion components (sliding horizontally on the frame): enable the entire cleaning and inspection mechanism to move a wide range in the horizontal direction (usually the X-axis), flexibly positioning itself above the openings of different workstations or different ton containers, adapting to the needs of production line layout or continuous cleaning of multiple containers, improving operational convenience and equipment utilization.

[0010] The first Y-axis assembly (vertically sliding on the motion assembly): carries the camera gimbal assembly and drives it to move precisely up and down along the vertical direction (Y-axis). This allows the detection camera to penetrate to different depths inside the container, performing a comprehensive visual scan of various areas such as the container walls and bottom.

[0011] The second Y-axis assembly (sliding vertically to the motion assembly): carries the high-pressure cleaning mechanism and drives it to move precisely up and down in the vertical direction (Y-axis). This allows the high-pressure nozzles to reach different depths inside the container, achieving comprehensive cleaning of all surfaces at all heights inside the container.

[0012] Camera gimbal assembly (mounted on the first Y-axis assembly, rotatable):

[0013] Rotatable: The gimbal provides rotational freedom in the horizontal and / or pitch directions, allowing the camera to flexibly adjust the viewing angle and image all surfaces inside the barrel (especially complex areas such as the bottom, corners, and welds) without blind spots.

[0014] Functions: Before cleaning, it can help locate the stained area (optional function). After cleaning, it can capture high-definition images of the inner surface of the bucket and automatically detect residual stains or cleanliness, replacing traditional manual visual inspection, ensuring that the cleaning quality meets the standards (thorough verification), and avoiding the subjectivity and omissions of manual inspection.

[0015] High-pressure cleaning mechanism (mounted on the second Y-axis assembly, rotatable):

[0016] Rotatable: The nozzle itself or the mounting base has the ability to rotate (such as self-spinning or oscillating), which, combined with the lifting motion, can dynamically adjust the spray angle and coverage of the high-pressure water flow.

[0017] Function: Generates high-pressure water jets or mists to directly impact, dissolve, and peel off dirt and residues adhering to the inner wall of the tank. Its rotatable characteristics, combined with Y-axis lifting and possible X-axis movement, overcome the angle and coverage limitations of traditional mechanical cleaning mechanisms, achieving thorough impact cleaning of stubborn areas such as complex curved surfaces, corners, and the bottom of the tank. It is the core execution component for improving cleaning thoroughness.

[0018] Oil mist collector (connected to high-pressure cleaning unit): During high-pressure cleaning, especially when cleaning oily residues, oil mist or aerosols are generated. The function of the oil mist collector is to actively extract and filter these oil mists and splashes generated during the cleaning process, preventing them from spreading and polluting the working environment, harming the health of operators, or affecting the clarity of camera detection, thereby improving the environmental friendliness and operational safety of the equipment.

[0019] Optionally, the frame includes columns, crossbeams, guide rails, and racks. The guide rails and racks are disposed on the crossbeams, the crossbeams connect two columns, and the racks mesh with gears of the motion component, the gears being connected to a motion motor.

[0020] Columns: As the vertical load-bearing frame of the equipment, they firmly support the upper beams, the entire motion assembly, the Y-axis assembly, and the cleaning and inspection mechanism, ensuring the overall rigidity and stability of the equipment.

[0021] Crossbeam: Horizontally connects two columns to form the upper frame of the machine, serving as a reference platform for mounting guide rails and racks, and providing direct support for the horizontal sliding of moving components.

[0022] Guide rail: Precisely fixed to the crossbeam, it cooperates with the slider (or guide wheel) on the motion component to provide low friction and high precision linear guidance for the horizontal movement of the motion component, restrict its movement direction (strictly along the X-axis), ensure smooth and stable movement, and reduce shaking and offset.

[0023] Rack: Also fixed on the crossbeam (usually parallel to the guide rail), its function is to mesh with the gear on the motion component to convert the rotational power of the motion motor into a precise linear driving force of the motion component along the guide rail direction. It is a key component for transmitting power.

[0024] Gear: Mounted on the motion component, meshing with the rack, directly transmitting the rotational motion output by the motion motor to the rack.

[0025] Motion motor: Fixed to the motion component, its output shaft drives the gear to rotate, providing a controllable power source for the movement of the entire motion component on the X-axis.

[0026] Optionally, the frame may also include a roller chassis for holding ton containers, the roller chassis having multiple rollers.

[0027] It provides a stable, rotatable support platform for the ton containers to be cleaned, significantly reducing the difficulty and labor intensity of manually moving the containers and improving cleaning coverage efficiency.

[0028] Optionally, the first Y-axis assembly includes a first lifting motor, a first lifting rail, a first lifting seat, a water pump, a water pipe, and a rotating head. The first lifting seat is slidably connected to the first lifting rail. The first lifting motor and the first lifting seat are connected by a screw and nut structure. The water pump is installed on the first lifting seat. The water pipe is connected to the water pump. The rotating head is rotatably connected to the water pipe.

[0029] First lifting rail: Vertically fixed on the motion component, it provides high-precision linear guidance for the up and down movement of the first lifting seat, ensuring that its movement trajectory is vertical and stable, and preventing shaking.

[0030] First lifting motor: Provides a controllable power source to drive the first lifting seat to move along the Y-axis (vertical direction).

[0031] Screw and nut structure: This structure precisely converts the rotational motion of the lifting motor into the linear lifting motion of the first lifting seat. When the screw rotates, the nut (fixed to the lifting seat) drives the lifting seat to move up and down along the lifting rail. This structure also has self-locking properties, reliably maintaining the position of the lifting seat in the event of power failure or shutdown.

[0032] First lifting platform: As the core load-bearing platform, it is connected to the lifting motor via a screw and nut structure and slidably connected to the lifting rail. Its core function is to support the water pump and drive its overall up and down movement, thereby adjusting the depth position of the high-pressure cleaning mechanism (water pump, water pipe, rotating head) inside the ton container.

[0033] Water pump: Fixedly installed on the first lifting platform, it rises and falls with the platform. Its core function is to generate the high-pressure water flow required for cleaning, providing the power source for cleaning. It pressurizes the input water (from an external water source) and outputs it.

[0034] Water pipe: Connected to the water pump outlet, it serves as a channel for delivering high-pressure water, guiding the high-pressure water generated by the water pump to the rotating head.

[0035] Rotary head: Rotarily connected to the end of the water pipe (usually the water pipe outlet). Its core function is:

[0036] High-pressure water jet: High-pressure water is sprayed onto the inner wall of the ton container in a specific form (such as direct jet, atomization, or multi-jet).

[0037] Achieving rotational motion: By rotating itself (possibly driven by an independent small motor or by water pressure), the spray direction of the high-pressure water flow is dynamically changed, significantly expanding the coverage angle of the single-point spray, enabling it to clean a larger circumferential area of ​​the inner wall of the tank and overcoming the coverage dead angle of the fixed nozzle.

[0038] Optionally, the rotating head is rotatably connected to the water pipe via a rotating seat. The rotating seat has two mutually perpendicular rotating shafts. One of the rotating shafts is coaxially connected to the water pipe, and the middle part of the rotating head is connected to the other rotating shaft. The two ends of the rotating head are a water injection head and a water pumping head, respectively.

[0039] Rotary seat:

[0040] It provides two rotational degrees of freedom: through two mutually perpendicular rotational axes (the first rotational axis and the second rotational axis), it provides two independent rotational capabilities for the rotating head.

[0041] The first rotating axis (coaxially connected to the water pipe): enables the entire rotating seat (along with the rotating head on it) to rotate 360 ​​degrees around the central axis of the water pipe. This rotation is mainly used to change the working direction of the water injection head or the water pumping head at a specific height, thereby expanding its coverage angle.

[0042] The second rotating shaft (connected to the middle of the rotating head): This shaft is used to drive the rotating head to rotate around an axis perpendicular to the water pipe axis (usually 180 degrees). Its core function is to achieve working mode switching: precisely rotating the water injection head or water extraction head of the rotating head to the position where it needs to act on the inner wall of the ton tank.

[0043] Rotating head:

[0044] Integrated dual-function connector: Its two ends are connectors with different functions.

[0045] Water inlet head: Connects to high-pressure water pipeline, has spray holes or nozzles inside, used to spray high-pressure cleaning water.

[0046] Pump head: Connects to the vacuum suction line (ultimately connected to the oil mist collector or vacuum pump), and has an internal suction port for sucking up residual liquid, oil mist or splashes after cleaning.

[0047] The middle section connects to the second rotating shaft: This design makes the entire rotating head act like a lever. When the second rotating shaft rotates, the rotating head will flip around the shaft, thereby alternately "presenting" the water injection head or the water suction head to the working position.

[0048] Mode switching: By controlling the rotation angle of the second rotating shaft (usually 180 degrees), it is possible to quickly and reliably switch between "high-pressure water injection cleaning mode" (water injection head working) and "vacuum suction mode" (water suction head working) without changing tools or adding additional mechanisms.

[0049] Optionally, the second Y-axis assembly includes a second lifting motor, a second lifting rail, a second lifting base, and a camera gimbal assembly. The second lifting base is slidably connected to the second lifting rail. The second lifting motor and the second lifting base are connected by a screw and nut structure. The camera gimbal assembly is connected to the second lifting base.

[0050] The second lifting rail is vertically fixed on the motion component, providing high-precision, low-friction linear guidance for the up-and-down movement of the second lifting platform. This ensures that its movement trajectory is vertical and stable, preventing the camera gimbal from shaking or shifting during the lifting process and guaranteeing imaging stability.

[0051] Second lifting motor + lead screw and nut structure:

[0052] Second lifting motor: Provides a controllable power source to drive the second lifting seat to move along the Y-axis (vertical direction).

[0053] The lead screw and nut structure converts the rotary motion of the lifting motor into the linear lifting motion of the second lifting seat with high precision and efficiency. This structure features high transmission accuracy and good self-locking (position retention even in the event of power failure), and is the core transmission component for achieving precise depth positioning of the camera.

[0054] The second lifting platform, serving as the core support platform, is connected to the lifting motor via a screw and nut structure and slidably connected to the lifting rail. Its main function is to stably support the camera gimbal assembly and drive its overall up-and-down movement, thereby precisely adjusting the camera's depth position inside the container (such as at different heights of the container opening, container wall, and container bottom).

[0055] Camera gimbal assembly: Fixedly mounted on the second lifting platform, it rises and falls with the platform. Its core function is:

[0056] Supports high-definition cameras: Install industrial cameras or vision sensors.

[0057] Provides multiple degrees of freedom: typically has horizontal rotation (Pan) and pitch rotation capabilities (driven by an internal motor).

[0058] Achieving blind-spot-free imaging: By rotating itself, the camera's viewing angle and orientation can be flexibly adjusted, enabling it to clearly image the inner wall, bottom, welds, corners, and other parts of the barrel from various directions and angles, overcoming the visual blind spots of a fixed viewing angle.

[0059] Optionally, the camera gimbal assembly includes a housing, a rotary motor, a mounting bracket, a rotating frame, and a camera body. The rotary motor is fixed inside the housing via the mounting bracket, the output shaft of the rotary motor is connected to the rotating frame, and the camera body is fixedly attached to the bottom of the rotating frame.

[0060] The core function of this structural design is to achieve precise pitch control of the camera body in the vertical plane, thereby expanding the coverage and flexibility of visual inspection. The housing provides structural support and protection for the entire gimbal assembly, ensuring the stable operation of the internal mechanisms; the mounting bracket securely mounts the rotary motor inside the housing, ensuring the stability of the power output; the rotary motor, as the drive source for pitch movement, drives the rotating frame to rotate through its output shaft, thereby directly controlling the spatial pointing angle of the camera body; the rotating frame, as a transmission and load-bearing component, converts the rotational motion of the motor into the pitch movement of the camera body and maintains its attitude stability. The overall structure works in concert, enabling the camera to dynamically adjust the shooting angle based on its lifting and positioning, effectively covering complex geometric surfaces such as the inner wall of the barrel, the bottom edge, and curved transition areas, significantly improving the comprehensiveness and clarity of image acquisition, and meeting the requirements for blind-spot-free inspection.

[0061] Optionally, a controller is also included, which is connected to the motion assembly, the first Y-axis assembly, the second Y-axis assembly, the camera gimbal assembly, the high-pressure cleaning mechanism, and the oil mist collector.

[0062] As the core control hub of the entire automated detection and cleaning system, this controller is responsible for the unified coordination and scheduling of all key execution components. It connects to and controls the motion components (enabling translation and positioning of the system in the X or Z axes), the first Y-axis component (driving the lifting and lowering of the cleaning mechanism), the second Y-axis component (driving the lifting and lowering of the camera gimbal), the camera gimbal component (controlling the camera's pitch and rotation angles), the high-pressure cleaning mechanism (starting and stopping the high-pressure water flow and adjusting cleaning parameters), and the oil mist collector (starting negative pressure suction and controlling the purification process), achieving integrated management of the entire equipment operation process. Its core function lies in precisely coordinating the working sequence and action logic of multiple subsystems, such as mechanical motion, visual inspection, cleaning operations, and contaminant collection, based on preset programs or real-time feedback signals. This ensures that the entire cleanliness detection and treatment process is executed automatically, efficiently, safely, and orderly, improving the overall intelligence level and operational consistency of the system.

[0063] Beneficial effects

[0064] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0065] The technical solution provided by this utility model automates the efficient and thorough cleaning of the inside of the ton container, and simultaneously detects the cleaning effect, while significantly reducing the intensity of manual operation and improving the convenience of operation.

[0071] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0072] Example

[0073] Combined with appendix Figure 1-2 An automatic cleaning and testing device for ton containers includes a frame 2, a motion component 3, a first Y-axis component 4, and a second Y-axis component 5. The motion component 3 is horizontally slidably connected to the frame 2. The first Y-axis component 4 and the second Y-axis component 5 are both vertically slidably connected to the motion component 3 along the Y-axis. The first Y-axis component 4 and the second Y-axis component 5 are respectively provided with a rotatable camera gimbal component 7 and a high-pressure cleaning mechanism 6. The high-pressure cleaning mechanism 6 is also connected to an oil mist collector 8.

[0074] Automated cleaning and inspection are achieved through multi-axis coordinated motion and intelligent control.

[0075] Positioning and entry: First, the motion component 3 moves horizontally (X direction) on the frame 2, positioning the entire cleaning and detection unit directly above the opening of the ton 1 to be cleaned.

[0076] Deep into the tank: The first Y-axis assembly 4 (with camera) and the second Y-axis assembly 5 (with nozzle) descend synchronously or sequentially from their initial positions along the vertical direction (Y direction), passing through the opening of the ton tank 1, and sending the camera and high-pressure nozzle into the tank to a specified depth.

[0077] Automatic cleaning process:

[0078] The second Y-axis assembly 5 drives the high-pressure cleaning mechanism 6 to move up and down (Y direction) inside the tank.

[0079] At the same time, the nozzle of the high-pressure cleaning mechanism 6 rotates or swings (turns) to change the direction of the high-pressure water jet.

[0080] The motion component 3 may make slight horizontal movements (X-direction) to adjust the position of the nozzle on the barrel opening plane.

[0081] The combined motion of these three elements (Y-axis lifting, nozzle rotation, and possible X-axis fine-tuning) allows the high-pressure water flow to dynamically cover the entire surface of the inner wall of the tank (including the vertical walls, the conical transition zone, the bottom plane of the tank, and all corners and crevices), achieving powerful and thorough rinsing and efficient removal of stains. Simultaneously, the oil mist collector 8 works to extract the oil mist generated during cleaning.

[0082] Automatic detection process:

[0083] After cleaning is completed (or during segmented testing), the first Y-axis component 4 drives the camera gimbal component 7 to move up and down (Y direction) inside the barrel.

[0084] The camera gimbal assembly 7 can be rotated horizontally or in pitch to adjust the camera's viewing angle.

[0085] Motion component 3 may perform horizontal movement (X-axis fine adjustment) to assist in positioning.

[0086] Through these combined movements, the camera can scan every area of ​​the inner wall of the barrel from all directions, capturing high-definition images.

[0087] Image data is transmitted to the control system, where image processing algorithms automatically analyze and determine whether the cleanliness meets the standards (such as whether there are residual stains, watermarks, etc.).

[0088] Results Feedback and Actions: The detection results are fed back to the control system. If the cleaning meets the standards, the equipment resets to prepare for the next cycle; if it does not meet the standards, an alarm may be triggered or the secondary cleaning process may be automatically started (repeating steps 3-4).

[0089] Reset: All components (Y-axis component, motion component 3) return to their initial positions according to the program control.

[0090] The frame 2 includes columns 21, crossbeams, guide rails 23 and racks 24. The guide rails 23 and racks 24 are mounted on the crossbeams, which connect the two columns 21. The racks 24 mesh with the gears of the motion assembly 3, which are connected to the motion motor 31.

[0091] Power start: The control system issues a command to drive the motion motor 31 to run.

[0092] Rotational output: The output shaft of the motion motor 31 drives the gear connected to it to start rotating.

[0093] Meshing transmission: The rotating gear meshes with the rack 24 fixed on the crossbeam. The teeth of the gear mesh tightly with the tooth grooves of the rack 24.

[0094] Rotation to linear motion: Since rack 24 is stationary, when the gear rotates, the meshing action between the gear and rack 24 forces the gear (and its connected motion motor 31 and the entire motion assembly 3) to move in a straight line along the length of rack 24 (i.e., the X-axis direction). Clockwise rotation of the gear drives the motion assembly 3 to move in one direction, while counterclockwise rotation drives it to move in the opposite direction.

[0095] Guiding constraint: While the gear rack 24 provides driving force, the slider (or guide wheel) fixed on the motion component 3 is in close cooperation with the guide rail 23 fixed on the crossbeam. The guide rail 23 constrains the motion freedom of the motion component 3, ensuring that it can only slide smoothly along the X-axis direction set by the guide rail 23, preventing deflection, jumping or jamming during movement.

[0096] Precise positioning: By precisely controlling the rotation angle, speed and direction of the motion motor 31 (usually in conjunction with encoder feedback), the position of the gear on the rack 24 can be precisely controlled, thereby achieving precise and programmable position control of the motion component 3 (and its Y-axis component, cleaning and detection mechanism) on the X-axis.

[0097] The frame 2 also includes a roller chassis 22 for holding the ton 1, and the roller chassis 22 is provided with multiple rollers.

[0098] Placing the ton container 1: The ton container 1 to be cleaned is hoisted or pushed onto the roller base 22. The bottom of the ton container 1 (usually its lower hoop or reinforcing rib structure) spans and presses against multiple parallel rollers, and the weight of the ton container 1 acts vertically on the rollers.

[0099] Rolling friction start-up: When the operator needs to rotate the ton 1, a horizontal tangential force (thrust) is applied to the side wall of the ton 1. Since the contact between the roller and the chassis frame (through the bearing) and between the roller surface and the bottom of the ton 1 is rolling friction, its resistance is much smaller than that of sliding friction.

[0100] Combined with appendix Figure 3The first Y-axis assembly 4 includes a first lifting motor 41, a first lifting rail 42, a first lifting seat 43, a water pump 44, a water pipe 45, and a rotating head 46. The first lifting seat 43 is slidably connected to the first lifting rail 42. The first lifting motor 41 and the first lifting seat 43 are connected by a screw and nut structure. The water pump 44 is installed on the first lifting seat 43. The water pipe 45 is connected to the water pump 44. The rotating head 46 is rotatably connected to the water pipe 45.

[0101] Lifting and positioning (Y-axis movement):

[0102] The control system commands the first lifting motor 41 to start and rotate.

[0103] The output shaft of the lifting motor drives the lead screw to rotate.

[0104] The rotating lead screw, through its threaded engagement with the nut fixed thereon, converts the rotational motion into a precise linear lifting motion (Y-axis direction) of the nut (and the first lifting seat 43 fixed thereon) along the first lifting rail 42.

[0105] The lifting platform drives the water pump 44, water pipe 45 and rotating head 46 on it to rise and fall together, thereby accurately positioning the cleaning nozzle to the required depth inside the ton container 1 (such as the top, wall and bottom of the container).

[0106] High-pressure water generation and transportation:

[0107] Water pump 44 starts, draws water from an external water source and pressurizes it to generate a high-pressure water flow.

[0108] High-pressure water is delivered from the outlet of water pump 44 to the end rotating head 46 through water pipe 45.

[0109] Rotary jet cleaning:

[0110] The high-pressure water flow reaches the inside of the rotating head 46.

[0111] The rotating head 46 rotates continuously or reciprocally around its axis under the action of a drive source (not specified in the figure, usually a small motor or water turbine).

[0112] As the rotating head 46 rotates, high-pressure water is ejected at high speed from its nozzles.

[0113] As the rotating head 46 rotates, the high-pressure water jet / mist it sprays also rotates or swings at high speed to scan.

[0114] Synergistic effect achieves coverage:

[0115] Lifting motion: Adjusts the height of the cleaning action on the inner wall of the tub.

[0116] Rotary jet: At a specific height level, a rotating water flow powerfully washes over the entire circumference of the inner wall of the tank at that height.

[0117] The combination of lifting and rotation allows the high-pressure water flow to systematically cover every point on the inner wall of the ton container (at different heights + 360 degrees circumference), achieving thorough cleaning without blind spots. The equipment can be programmed to control the lifting speed, position, and rotation speed according to the level of soiling, optimizing the cleaning effect.

[0118] The rotating head 46 is rotatably connected to the water pipe 45 via a rotating seat. The rotating seat has two mutually perpendicular rotating shafts. One rotating shaft is coaxially connected to the water pipe 45, and the middle part of the rotating head 46 is connected to the other rotating shaft. The two ends of the rotating head 46 are a water injection head and a water pumping head, respectively.

[0119] The control system drives two independent rotary motors 72 (usually one for each rotary axis).

[0120] The first rotating shaft motor drives the rotating seat (together with the entire rotating head 46) to rotate horizontally around the axis (Z-axis) of the water pipe 45, pointing the water injection head or water pumping head to the required circumferential angle.

[0121] Second high-pressure water injection cleaning: When cleaning is required, the control system starts water pump 44.

[0122] High-pressure water flows through water pipe 45 and the internal channel of the rotating seat (which must have a rotating seal) to the water injection head.

[0123] High-pressure water is ejected at high speed from the nozzle of the water injection head, impacting and washing away dirt on the target surface.

[0124] During the cleaning process, the control system can control the movement of the dual rotating axes in real time, so that the jet water can dynamically scan and cover complex surfaces, or deliver a targeted and powerful impact on stubborn stains.

[0125] Negative pressure suction recovery:

[0126] When it is necessary to remove residual liquid or dirt, the control system activates the oil mist collector 8 or a separate vacuum pump to generate negative pressure in the suction pipe.

[0127] The control system drives the dual rotating shafts to precisely rotate and position the pump head to the area that needs to be pumped (such as the lowest point of the tank or a corner).

[0128] The negative pressure is transmitted to the suction port of the pump head through another channel inside the rotating seat (which also requires a rotating seal).

[0129] Residual sewage, dirt particles, foam, etc. are forcefully sucked into the pump head, pumped away through the pipeline, and collected for treatment.

[0130] Functional collaboration and switching:

[0131] The cleaning process can be flexibly arranged: for example, first inject water to clean a certain area, and then immediately rotate 180 degrees and use the same positioning water head to pump away the sewage in that area; or when cleaning the bottom of the tank, slowly rotate horizontally while spraying water with the injection head, and at the same time use the water head to continuously pump at the lowest point to prevent water accumulation.

[0132] The integrated design of the dual-function head avoids frequent tool changes. A simple rotation of the rotating head 46 allows for quick switching between water injection and suction modes, greatly improving operational smoothness and efficiency. The rotating head 46, driven by a shaft motor, controls the rotation of the water injection and suction heads, which then proceed into the ton container 1 for further processing.

[0133] The second Y-axis assembly 5 consists of a second lifting motor 51, a second lifting rail 52, a second lifting seat 53, and a camera gimbal assembly 7. The second lifting seat 53 is slidably connected to the second lifting rail 52. The second lifting motor 51 and the second lifting seat 53 are connected by a screw and nut structure. The camera gimbal assembly 7 is connected to the second lifting seat 53.

[0134] Depth positioning (Y-axis motion):

[0135] The control system commands the second lifting motor 51 to start and rotate.

[0136] The output shaft of the lifting motor drives the lead screw to rotate.

[0137] The rotating lead screw, through its threaded engagement with the nut fixed thereon, converts the rotational motion into a precise linear lifting motion (Y-axis direction) of the nut (and the second lifting seat 53 fixed thereon) along the second lifting rail 52.

[0138] The lifting platform moves the camera gimbal assembly 7 (including the camera) on it up and down together, thereby accurately positioning the camera lens at the specific depth to be detected inside the ton 1.

[0139] View adjustment (gimbal rotation):

[0140] Once the camera reaches the target depth, the drive motor inside the camera gimbal assembly 7 is activated.

[0141] The horizontal rotation motor 72 drives the gimbal (and camera) to rotate 360 ​​degrees horizontally around the vertical axis.

[0142] The pitch motor drives the camera to pitch around the horizontal axis at a certain angle (such as ±90 degrees).

[0143] By combining horizontal rotation and pitch swing, the camera can precisely point its field of view (FOV) at any region of interest (ROI) on the inner wall, bottom, or top of the barrel.

[0144] Collaborative work enables full-coverage detection:

[0145] Lifting motion: systematically changing the camera's detection height layer (e.g., scanning layer by layer from top to bottom).

[0146] Gimbal rotation: At each specific height level, the horizontal rotation covers the entire circumference of that level, and the pitch adjustment optimizes the imaging angle of the barrel wall surface, transition zone, or barrel bottom plane.

[0147] The coordinated programming control of lifting and gimbal rotation (such as spiral scanning path and layered and regional scanning) ensures that the camera can capture clear images of every area on the inner surface of the ton 1 without any omissions.

[0148] Image Acquisition and Processing: After positioning and adjusting the viewing angle, the camera acquires high-definition images or video streams. This data is transmitted to the image processing system, where algorithms automatically analyze for residual stains, watermarks, rust, or other defects to determine whether the cleanliness meets the standards.

[0149] Combined with appendix Figure 4 The camera gimbal assembly 7 includes a housing 71, a rotary motor 72, a mounting bracket 73, a rotating frame 74, and a camera body 75. The rotary motor 72 is fixed inside the housing 71 via the mounting bracket 73. The output shaft of the rotary motor 72 is connected to the rotating frame 74, and the camera body 75 is fixedly attached to the bottom of the rotating frame 74. When the system is working, the control system sends a command to the rotary motor 72 according to the detection needs, driving its output shaft to rotate at a predetermined angle and speed. This rotational motion is transmitted to the rotating frame 74 through a rigid connection, causing the rotating frame 74 to rotate around the center line of the motor output shaft. Since the camera body 75 is fixed below the rotating frame 74, its spatial attitude changes synchronously with the rotating frame 74, realizing pitch adjustment in the vertical direction. By precisely controlling the direction and angle of rotation of the rotary motor 72, the shooting angle of the camera can be adjusted in real time and continuously, so that its optical axis is aligned with a specific target area inside the barrel. Combined with the vertical displacement provided by the lifting mechanism and the horizontal rotation function that the gimbal may have, this pitch structure together constitutes a multi-degree-of-freedom stereo scanning capability, realizing accurate imaging and full coverage of any position on the internal surface of the ton barrel 1.

[0150] The equipment also includes a controller connected to the motion component 3, the first Y-axis component 4, the second Y-axis component 5, the camera gimbal component 7, the high-pressure cleaning mechanism 6, and the oil mist collector 8. During system operation, the controller sends control signals to each connected component according to a preset automation program or host computer instructions, following a predetermined logical sequence. For example, when entering the detection stage, the controller first drives the motion component 3 to position the detection unit at the barrel opening, then controls the second Y-axis component 5 to lower the camera gimbal component 7 to a specified height, and simultaneously commands the camera gimbal component 7 to adjust its pitch and rotation angles to complete multi-angle image acquisition. After detection is completed, the controller switches to cleaning mode, commands the first Y-axis component 4 to lower the high-pressure cleaning mechanism 6 into the barrel, simultaneously activates the high-pressure cleaning mechanism 6 to spray water, and activates the oil mist collector 8 to capture oil mist and splashes generated during the cleaning process in real time. Throughout the process, the controller can also receive feedback signals from sensors or vision systems to achieve closed-loop control, such as dynamically adjusting the cleaning area or extending the cleaning time based on image recognition results, thereby achieving fully automated operation from positioning, detection, cleaning to purification.

[0151] Operating principle:

[0152] The equipment achieves comprehensive, seamless coverage of the internal space of the ton container by precisely moving in the X (horizontal) and Y (vertical) directions, combined with the independent rotation of the cleaning nozzles and detection cameras. It utilizes the physical rinsing of high-pressure water jets for efficient decontamination (cleaning), employs machine vision for automated cleanliness verification (detection), and ensures environmental cleanliness through oil mist collection. The entire process is automated, significantly reducing manual intervention and resolving the problems of low efficiency, incomplete cleaning, high labor intensity, and inconvenient operation mentioned in the background technology.
