Description

Technical Field

[0001] The present invention relates to the technical field of spraying equipment, and specifically to an intelligent control circuit multi-functional spraying equipment. Background Art

[0002] With the continuous improvement of the requirements for railway line operation and maintenance, the demand for the protection and lubrication of track fastener bolts, corrosion prevention, and the cleaning of surrounding weeds is increasing day by day. Automated and intelligent multi-functional spraying equipment has become an important development direction in the field of track maintenance. In recent years, track-specific spraying equipment has gradually realized the transformation from a single operation function to the integration of multiple processes. Some systems adopt modular design, realizing the combination of multiple operation modes such as oil spraying, greasing, and weeding, providing strong support for the refined maintenance and long-term operation of railway lines. With the integrated application of emerging technologies such as the Internet of Things, intelligent detection, and automatic control, the reliability, operation efficiency, and adaptability of multi-functional track operation equipment are gradually improving, and the industry has broad development prospects.

[0003] In the prior art, CN219210343U discloses an automatic track bolt greasing device. This automatic track bolt greasing device is equipped with a sensor to identify bolts. The controller receives the signal and outputs it to the solenoid valve. The solenoid valve opens for spraying, and the greasing work is carried out by the machine to achieve the purpose of fine operation, avoiding the phenomenon of ballast contamination and environmental pollution caused by excessive greasing area, and being able to save manpower and improve the greasing work efficiency.

[0004] In the prior art, track spraying equipment usually has problems such as insufficient structural rigidity, scattered functional modules, and low efficiency of power transmission and fluid switching. Most equipment can only adapt to a single road condition, with poor adaptability to complex track obstacles, curve sections, and variable working conditions, and lacks a mechanical structure for lifting over obstacles and synchronous linkage of multiple mechanisms. The mechanical integration of nozzle switching, angle adjustment, and pressure control is low, unable to meet the fine spraying requirements of multiple media, high frequency, and different parts on site, resulting in limited spraying uniformity, medium adhesion, and automation. At the same time, the cleaning efficiency is low, the risk of liquid path mixing is high, and manual maintenance is frequent, making it difficult to support large-scale and long-term intelligent maintenance operations of railway lines. Therefore, those skilled in the art have provided an intelligent control circuit multi-functional spraying equipment to solve the problems raised in the above background. Summary of the Invention

[0005] The purpose of the present invention is to provide an intelligent control circuit multi-functional spraying equipment to solve the problems raised in the prior art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions: The spraying device includes a rail running mechanism, a spraying mechanism, a supply mechanism, and a self-cleaning mechanism. The spraying mechanism, the supply mechanism, and the self-cleaning mechanism are all fixedly connected to the rail running mechanism. The spraying mechanism and the self-cleaning mechanism are both connected to the supply mechanism, and the spraying mechanism and the self-cleaning mechanism are connected to each other.

[0007] By adopting the above technical solution, the spraying device realizes automatic movement along the railway track through the rail running mechanism. The spraying mechanism, the supply mechanism, and the self-cleaning mechanism are all fixed on the rail running mechanism by a fastening connection method, ensuring the integrity of the equipment structure and the stability of operation.

The driving motor is fixedly connected to the lifting and obstacle-crossing component, and the lifting and obstacle-crossing component is fixedly connected to the vehicle frame. The driving motor is connected to the transmission belt in a transmission manner, the transmission belt is connected to the transmission shaft in a transmission manner, the transmission shaft is connected to the double-row guiding wheels in a transmission manner, and the transmission shaft, the double-row guiding wheels, and the double-row rail are in rolling connection.

[0009] By adopting the above technical solutions, the track running mechanism realizes the smooth operation and precise control of the equipment on the railway track through the division of labor and cooperation of the track guiding component, the lifting and obstacle-crossing component, and the braking and locking component. During specific implementation, the double-track in the track guiding component provides a dedicated track foundation for the movement of the equipment. The double-row guiding wheels are in rolling connection with the double-track, ensuring the stable progress of the equipment along the track direction and effectively preventing deviation. The transmission shaft, as the power transmission center, is mechanically connected to the double-row guiding wheels to ensure synchronous power distribution. The transmission belt connects the driving motor and the transmission shaft, efficiently transmitting the rotational power of the driving motor to the transmission shaft to achieve the efficient operation of the overall drive. The vehicle frame, as the bearing and installation foundation, is firmly connected to the lifting and obstacle-crossing component, the double-track, and each functional module, enhancing the overall structural rigidity and durability of the equipment. The driving motor is firmly connected to the lifting and obstacle-crossing component by a fastening method and is also directly connected to the transmission belt for transmission, enabling the control of the start, stop, and speed adjustment of the equipment according to the operation requirements. The lifting and obstacle-crossing component is firmly connected to the vehicle frame, facilitating the automatic lifting and reset of the equipment body through lifting actions when encountering obstacles such as uneven tracks and turnouts, ensuring the safe and smooth operation of the obstacle-crossing operation. Through the close mechanical connection and reasonable power transmission of the above components, the automatic guidance, efficient power transmission, flexible adaptation to obstacle crossing, and integrated installation of multiple mechanisms of the spraying equipment on the railway line are realized, improving the running stability, obstacle-crossing reliability, and operation efficiency of the equipment during operation.

The gyroscope is firmly connected to the vehicle frame, the infrared sensor is firmly connected to the vehicle frame, the clamping electromagnet is firmly connected to the rotating block, the clamping magnetic block is slidably connected to the rotating block, the rotating block is rotatably connected to the follower block, the clamping elastic member is firmly connected to the clamping magnetic block, the clamping electromagnet and the clamping magnetic block are driven by magnetic poles repelling each other, the clamping magnetic member abuts against the transmission shaft, the follower block is rotatably connected to the transmission shaft, the rotating block is rotatably connected to the follower block, the lifting hydraulic cylinder is connected to the follower block for transmission, the lifting hydraulic cylinder is firmly connected to the vehicle frame, the transmission shaft is connected to the rotating rod, the rotating rod is firmly connected to the rotating block, the rotating rod is rotatably connected to the support wheel, and the support wheel abuts against the double-track.

[0010] By adopting the above technical solution, the lifting and obstacle-crossing assembly uses a gyroscope and an infrared sensor to detect the attitude of the device and obstacles ahead in real time. The gyroscope is firmly connected to the vehicle frame to continuously monitor the tilting state of the device, and the infrared sensor is firmly connected to the vehicle frame to actively sense obstacles on the track. When an obstacle or track undulation is detected, the clamping electromagnet realizes the clamping function by being firmly connected to the rotating block; the clamping magnetic block is slidably connected to the rotating block and maintains a restoring force through the action of the clamping elastic member. The clamping electromagnet and the clamping magnetic block perform instantaneous unlocking and reset actions based on the principle of magnetic pole repulsion. The clamping magnetic member directly abuts against the transmission shaft to clamp or release the transmission shaft. The follower block is rotationally connected to the transmission shaft and is linked with the rotating block. The rotational connection between the rotating block and the follower block makes the lifting action of the device smoother and more synchronous. The lifting hydraulic cylinder is transmissionally connected to the follower block and is firmly connected to the vehicle frame. When an obstacle is detected, it pushes the follower block to drive the whole machine to rise and cross the obstacle. After crossing the obstacle, the hydraulic cylinder resets and the device automatically descends back to the working position. The transmission shaft is connected to the rotating rod, and the rotating rod is then firmly connected to the rotating block. At the same time, the rotating rod is rotationally connected to the supporting wheel to transmit the lifting action to the supporting wheel. The supporting wheel abuts against the double-track, ensuring reliable contact with the track during the lifting process of the device. Through the coordinated action of the above-mentioned parts, the lifting and obstacle-crossing assembly can realize the real-time attitude monitoring of the device, automatic identification of obstacles and lifting and crossing. The clamping structure ensures the safe and reliable connection between the power and the body during the lifting process. The follower and hydraulic actions improve the adaptability of the device to complex track environments, greatly enhancing the obstacle-crossing stability and operation continuity of the device.

[0011] Furthermore, the brake locking assembly includes a magnetic suction cup, a brake lever, a magnetic sliding block, a friction plate, a reset elastic member and a control electromagnet. The magnetic sliding block is slidably connected to the vehicle frame, the control electromagnet is firmly connected to the vehicle frame, the control electromagnet and the magnetic sliding block are driven by magnetic pole repulsion, the magnetic sliding block is hinged to the brake lever, the brake lever is firmly connected to the magnetic suction cup, the brake lever is hinged to the vehicle frame, the friction plate is firmly connected to the magnetic suction cup, the magnetic suction cup is slidably connected to the vehicle frame, the reset elastic member is firmly connected to the vehicle frame, the reset elastic member is firmly connected to the magnetic suction cup, the magnetic suction cup is magnetically connected to the double-track, and the friction plate abuts against the double-track.

[0012] By adopting the above technical solution, the brake locking assembly realizes the precise braking and safe locking of the spraying equipment on the track through the combination of a magnetic suction cup, a brake lever, a magnetic sliding block, a friction plate, a reset elastic member and a control electromagnet. During specific implementation, the magnetic sliding block is slidably connected to the vehicle frame. Under the action of the control electromagnet, a magnetic pole repulsive force is formed between the magnetic sliding block and the control electromagnet, driving the magnetic sliding block to act; the magnetic sliding block is connected to the brake lever through a hinge, driving the brake lever to act. One end of the brake lever is fixedly connected to the magnetic suction cup, and the other end is fixed to the vehicle frame through a hinge, forming a reliable torque transmission path. The friction plate is fixedly connected to the magnetic suction cup. When the magnetic suction cup is slidably connected to the vehicle frame to the braking position, the magnetic suction cup is tightly adsorbed to the double-row track through magnetic suction, and the friction plate directly abuts against the double-row track, generating a stable frictional force to achieve mechanical braking and locking. One end of the reset elastic member is fixedly connected to the vehicle frame, and the other end is fixedly connected to the magnetic suction cup, and can quickly reset the magnetic suction cup and related braking structures after releasing the suction force of the control electromagnet. The entire working process is as follows: when the equipment needs to be braked, the control electromagnet releases the magnetic pole repulsive force to push the magnetic sliding block, driving the brake lever to act. The magnetic suction cup moves below the track and is magnetically locked, and the friction plate fits with the track to generate braking force; after braking, the reset elastic member provides an elastic restoring force to reset each mechanism and prepare for the next action. This structure ensures the braking safety, stability and repeatability of the equipment during spraying operations and movement through the dual locking mechanism of magnetic suction and friction, combined with a reliable mechanical transmission and reset structure, improving the overall operation safety level and track adaptability of the machine.

[0013] Furthermore, the spraying mechanism includes a switching component, a telescopic hydraulic cylinder and a pressure regulating component. The switching component is fixedly connected to the telescopic hydraulic cylinder, the pressure regulating component is communicated with the switching component, and the switching component is communicated with the supply mechanism.

[0014] By adopting the above technical solution, the spraying mechanism is composed of a switching component, a telescopic hydraulic cylinder and a pressure regulating component, which ensures the multiple adjustable capabilities of the equipment for different spraying functions, spraying positions and spraying pressures. In specific implementation, the switching component is tightly connected to the telescopic hydraulic cylinder, and the linear motion capability of the hydraulic drive is used to realize the telescopic movement of the spraying component in the working space, which can adapt to the spatial position of different fastener bolts. The pressure regulating component is connected to the switching component, and the spraying pressure can be dynamically adjusted according to the needs of different spraying media to ensure the uniformity and adhesion of the spraying effect. The switching component is connected to the supply mechanism, and the selection and conversion of various liquids (such as oil or herbicide) are realized through the internal flow path switching, so that the spray head can flexibly switch the functions of refueling, oiling, weeding, etc. The workflow is: according to the operation instruction, the supply mechanism transfers the specified liquid to the spray head through the switching component, the pressure regulating component controls the spraying pressure in real time, and the telescopic hydraulic cylinder adjusts the spray head to the target position to realize the precise spraying of fastener bolts or target areas. The switching component automatically changes the spray path when the function needs to be switched, ensuring that different operating fluids can be quickly switched without mixing. Through the above structure, the parts achieve efficient integration of fluid, power and function, making the equipment have the advantages of flexible switching, precise position adjustment and intelligent pressure control, improving the adaptability, automation level and spray uniformity of the spraying operation, and meeting the various spraying needs of railway lines.

[0015] Furthermore, the switching assembly includes a ball gear, a driving gear, a rotating motor, an angle motor, an assembly pipe, a spray pipe and a limit switching block. The ball gear and the limit switching block are abutted, the limit switching block and the assembly pipe are slidingly connected, the assembly pipe and the frame are fastened, the telescopic hydraulic cylinder and the assembly pipe are fastened, the telescopic hydraulic cylinder and the rotating motor are transmission-connected, the rotating motor and the limit switching block are transmission-connected, the angle motor and the limit switching block are fastened, the angle motor and the driving gear are transmission-connected, the driving gear and the ball gear are transmission-connected, the ball gear and the spray pipe are transmission-connected, the spray pipe and the assembly pipe are slidingly connected, and the spray pipe and the pressure regulating assembly are connected.

[0016] By adopting the above technical solution, the switching assembly realizes multi-directional, multi-functional precise switching and positioning of the spray head through a multi-level combination of ball gears, drive gears, rotary motors, angle motors, assembly pipes, spray pipes and limit switch blocks. In specific implementation, the ball gear abuts against the limit switch block to form a switch stop, and the limit switch block is slidably connected to the assembly pipe to ensure reliable connection of the spray channel during the switching action. The assembly pipe, as a structural bearing member, is tightly connected to the frame and the telescopic hydraulic cylinder, so that the entire spray mechanism has stability and mobility in space. The telescopic hydraulic cylinder is not only tightly connected to the assembly pipe, but also connected to the rotary motor by transmission, providing the spray mechanism with a composite drive capability of telescopic and rotation. The rotary motor is connected to the limit switch block through a transmission mechanism, driving the limit switch block to rotate, and realizing the preliminary directional switching of the spray head. The angle motor is tightly connected to the limit switch block, and is driven by the drive gear and the ball gear to realize fine angle adjustment of the spray head; the drive gear and the ball gear are further linked, and the ball gear is finally connected to the spray pipe by transmission, ensuring that the spray pipe can complete precise rotation and switching in multiple degrees of freedom. The spray tube is slidably connected to the assembly tube to adapt to the dynamic changes in the position of the spray head, and is connected to the pressure regulating assembly to ensure smooth supply of fluids under different pressures. The working process is as follows: according to the system instructions, the rotary motor and the angle motor work together to drive the ball gear and the drive gear to accurately switch the operating direction and functional channel of the spray tube, and the telescopic hydraulic cylinder adjusts the spray head to the target operating position; after the spraying is completed, the limit switch block cooperates with the assembly tube to complete the reset and prepare for the next operation cycle. This structure realizes the multi-functional switching, position adjustment and efficient fluid channel docking of the spray head through multi-stage mechanical transmission and precise limit coordination, effectively improving the equipment's automation level and operational adaptability in multi-scenario, multi-angle and multi-liquid spraying operations, and ensuring the continuity, uniformity and reliability of the spraying operation.

[0017] Furthermore, the pressure regulating assembly includes a pressure regulating head, a pressure sensor, a nozzle indexing plate, a indexing motor, an electromagnetic telescopic rod and an iris assembly. The iris assembly is provided with two groups. The pressure sensor and the iris assembly are fastened together, the iris assembly and the pressure regulating head are fastened together, the indexing motor and the pressure regulating head are fastened together, the indexing motor and the electromagnetic telescopic rod are transmission-connected, the electromagnetic telescopic rod and the nozzle indexing plate are transmission-connected, and the nozzle indexing plate and the iris assembly are transmission-connected.

[0018] By adopting the above technical solution, the pressure regulating assembly realizes intelligent, graded and dynamic adjustment of the spraying pressure through the coordinated cooperation of the pressure regulating head, pressure sensor, nozzle indexing plate, indexing motor, electromagnetic telescopic rod and two groups of iris components. In specific implementation, the pressure regulating head is the main force-bearing and adjustment structure, which is tightly connected with the iris component and the pressure sensor to form a closed and adjustable spraying channel. The tight connection between the pressure sensor and the iris component realizes real-time monitoring and feedback of the spraying pressure. The indexing motor is tightly connected to the pressure regulating head, and the electromagnetic telescopic rod is driven by the transmission mechanism. The electromagnetic telescopic rod is connected to the nozzle indexing plate through transmission, so that the nozzle indexing plate can accurately adjust the position according to the control command. The transmission connection between the nozzle indexing plate and the iris component further realizes the fine adjustment of the opening of the spray nozzle channel. The iris component is provided with two groups of structures, which can control the spraying flow and atomization state according to different working conditions, thereby improving the spraying uniformity and application range. The working process is as follows: during the spraying operation, the pressure sensor continuously monitors the pressure inside the nozzle and feeds back the data to the indexing motor in real time. The indexing motor drives the electromagnetic telescopic rod to rotate the nozzle indexing disk to drive the iris assembly to fine-tune the nozzle opening, thus realizing the closed-loop control of the spraying pressure and flow rate. Through the above structure, the pressure regulating assembly has multi-level pressure regulation, high-sensitivity feedback and multi-functional spraying adaptability, which effectively ensures that all kinds of oils and herbicides can achieve the best spraying effect under different pressures and flows, improves the level of equipment automation and intelligence, and significantly enhances the stability and consistency of the spraying operation.

[0019] Furthermore, the supply mechanism includes a cleaning fluid storage tank, a herbicide tank, a spray tank, a pressure pump and a liquid level detector. The cleaning fluid storage tank, the herbicide tank and the spray tank are all tightly connected to the frame. The cleaning fluid storage tank, the herbicide tank and the spray tank are all connected to the pressure pump. The liquid level detectors are all tightly connected to the cleaning fluid storage tank, the herbicide tank and the spray tank.

[0020] By adopting the above technical solution, the supply mechanism realizes the automatic switching of multiple media and precise liquid supply through the organic combination of the cleaning liquid storage tank, the weeding agent tank, the oil spraying tank, the pressure pump and the liquid level detector. During specific implementation, the cleaning liquid storage tank, the weeding agent tank and the oil spraying tank are respectively fixedly connected to the vehicle frame, serving as three independent liquid supply units of the system, which can accommodate working liquids with different functions at the same time, ensuring efficient transfer and liquid supply during the operation process. Each storage tank is connected to the pressure pump, and the pressure pump is used to increase the pressure of various liquids to ensure that the liquids can be stably and evenly transported to the spraying mechanism or the self-cleaning mechanism. The liquid level detectors are respectively fixedly connected to the cleaning liquid storage tank, the weeding agent tank and the oil spraying tank, and continuously monitor the remaining liquid in each storage tank and feedback the liquid level status to the control system to prevent liquid shortage or abnormal liquid supply. The working process is as follows: according to different operation requirements, the control system commands the pressure pump to open the corresponding liquid supply path of the storage tank, pressurize the specified liquid and send it to the spray head or the cleaning nozzle. The liquid level detector continuously monitors and automatically alarms or switches to supplement when the liquid level is too low, ensuring the continuous progress of spraying and cleaning operations. The above structure realizes the flexible switching of multiple media, continuous and stable liquid supply and automatic response to liquid shortage through the triple guarantees of independent storage tanks, high-efficiency pressurization and intelligent detection, improves the operation reliability and automation level of the spraying equipment, and reduces the manual maintenance requirements and the risk of liquid mixing.

[0021] Furthermore, the self-cleaning mechanism includes a check valve, a pulse cleaning nozzle and a box body cleaning component. The box body cleaning component is fixedly connected to the supply mechanism, the check valve is fixedly connected to the assembly pipe, the cleaning liquid storage tank, the weeding agent tank and the oil spraying tank are all connected to the check valve, the pulse cleaning nozzle is fixedly connected to the limit switching block, and the pulse cleaning nozzle is connected to the cleaning liquid storage tank.

[0022] By adopting the above technical solution, the self-cleaning mechanism realizes the automatic and efficient cleaning of the spraying system relying on the organic cooperation of the check valve, the pulse cleaning nozzle and the box body cleaning component. During specific implementation, the box body cleaning component is firmly combined with the supply mechanism through a fastening connection method, providing an independent and stable cleaning function module for the equipment. The check valve is firmly connected to the assembly pipe and is connected to the cleaning liquid storage tank, the weeding agent tank and the oil spraying tank, and can effectively control the one-way flow of different liquids during the cleaning and operation processes, preventing liquid backflow and cross-contamination. The pulse cleaning nozzle is firmly connected to the limit switching block to ensure that the nozzle can be accurately positioned at the part to be cleaned along with the switching action of the spraying head. The pulse cleaning nozzle is directly connected to the cleaning liquid storage tank and can spray the cleaning liquid in a high-pressure pulse manner during the cleaning process, effectively flushing the inner and outer walls of the spraying pipeline and the nozzle. The working process is as follows: during the operation completion or spraying switching stage, the system controls the check valve to automatically switch, and the cleaning liquid enters the assembly pipe and the spraying channel unidirectionally from the cleaning liquid storage tank through the check valve. The pulse cleaning nozzle is controlled to open, and the cleaning liquid is atomized and impacts the key parts of the spraying system with high frequency pulses. At the same time, the box body cleaning component acts on the surface of the overall structure to achieve a full-automatic flushing. Through the above structure and process, the check valve realizes the directional control of the fluid, the pulse cleaning nozzle realizes the efficient decontamination of the spraying system, and the box body cleaning component realizes the full coverage, improving the self-cleaning ability of the spraying equipment, significantly reducing the risk of nozzle blockage and residue accumulation, extending the service life of the equipment, and improving the operation continuity and reliability.

[0023] Furthermore, the box body cleaning component includes a cleaning nozzle and a drain valve. The cleaning liquid storage tank is connected to the cleaning nozzle, and the cleaning nozzles are all arranged above the weeding agent tank and the oil spraying tank, and the drain valves are all arranged at the bottoms of the weeding agent tank and the oil spraying tank.

[0024] By adopting the above technical solution, during the specific implementation of the box body cleaning component, the cleaning liquid storage tank is connected to the cleaning nozzle to ensure that the cleaning liquid can be stably transported to each cleaning point. The cleaning nozzles are evenly arranged above the weeding agent tank and the oil spraying tank, and can directly spray the high-pressure cleaning liquid onto the inner wall and the top of the tank body, realizing the full-coverage flushing of the inner wall of the tank body and quickly removing the residual agent or oil stain. The drain valves are respectively arranged at the bottoms of the weeding agent tank and the oil spraying tank, facilitating the timely discharge of the flushing waste liquid and sediment impurities in the tank after the cleaning is completed, preventing liquid accumulation and blockage. The working process is as follows: when starting the box body cleaning process, the cleaning liquid storage tank supplies liquid to the cleaning nozzle, and the nozzle aligns with the inside of the tank body for efficient flushing. The dirty liquid naturally flows to the bottom of the tank along the gravity, and is discharged orderly by the drain valve. Through the above structure, the cleaning nozzle ensures the effective distribution and spraying of the cleaning liquid, and the drain valve ensures the quick and thorough discharge of the waste liquid. The overall design not only realizes the automatic cleaning and quick drainage of the box body and the liquid tank, effectively preventing impurity residue and cross-contamination, but also improves the cleaning and maintenance efficiency of the equipment and the long-term operation reliability.

[0025] Compared with the prior art, the beneficial effects of the present invention are: Through the rigid stratification and tight connection of the track guiding component and the lifting and obstacle-crossing component, the present invention enables the spraying equipment to automatically adapt to different rail types and obstacle conditions on the railway track. The double-row guiding wheels are in rolling cooperation with the double-row track. With the synchronous cooperation of the transmission shaft, transmission belt, vehicle frame, and driving motor, the power is ensured to be continuous and the walking is stable. For lifting and obstacle-crossing, the composite detection of the gyroscope and infrared sensor is adopted. The magnetic poles of the clamping electromagnetic block and the clamping magnetic block repel each other and mechanically slide, realizing rapid obstacle recognition and efficient lifting. The follower block, lifting hydraulic cylinder, rotating block, and supporting wheel form an integral linkage mechanism, improving the smoothness and reliability of obstacle-crossing. At the spraying operation end, the switching component, telescopic hydraulic cylinder, and pressure regulating component adopt a multi-axis, multi-tooth, indexing, and intelligent feedback structure. Among them, the close transmission and sliding cooperation of the spherical gear, driving gear, limit switching block, and angle motor, and the sliding connection between the assembly pipe and the spraying pipe form a high-degree-of-freedom nozzle switching, angle adjustment, and positioning mechanism. The pressure regulating component combines a dividing motor, electromagnetic telescopic rod, and two groups of iris components, and combines the real-time feedback of the pressure sensor to dynamically adjust the opening degree and flow rate of the nozzle channel, realizing precise pressure control of different media, greatly improving the uniformity and adhesion reliability of spraying, and supporting high-frequency switching and automatic segmented operation. The self-cleaning and supply system realizes independent liquid supply for multiple liquid tanks, one-way anti-mixing, automatic pressurization, and liquid shortage monitoring through the highly integrated check valve, pulse cleaning nozzle, box body cleaning component, pressure pump, and liquid level detector. The cleaning nozzle adopts a distributed high-pressure structure and is arranged at the bottom of the drain valve, integrating the tank body cleaning and waste liquid discharge. The pulse nozzle is linked with the limit switching block for precise positioning, realizing efficient flushing of the entire channel during the operation gap to prevent nozzle blockage. The liquid level detection, pressure pump, and storage tank module cooperate to ensure the connection of the switching, replenishment, and spraying operations of each medium, reducing manual maintenance and failure rate, and significantly improving the continuous and reliable operation ability and overall intelligent level of the equipment.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
