Description

Technical Field

[0001] The invention belongs to cleaning equipment, and in particular relates to a semi-automatic mobile cleaning machine. Background Art

[0002] In the field of large vehicle cleaning, there are currently two main traditional cleaning methods: manual cleaning and automatic cleaning. However, these two cleaning methods cannot meet the high requirements of modern cleaning operations for efficiency, cost and flexibility. First of all, although the manual cleaning method is flexible in operation, the scope of operation is extremely limited. It can only clean parts of the vehicle, and it is difficult to achieve a comprehensive and efficient cleaning effect. In addition, manual cleaning requires the cooperation of multiple people, which not only has high time and labor costs, but also the cleaning quality depends to a large extent on the experience and skills of the operator, and it is difficult to ensure the consistency and stability of the cleaning. When faced with large-scale cleaning tasks, the manual cleaning method obviously cannot meet the needs of efficient and rapid completion of cleaning operations. On the other hand, although the automatic cleaning method has improved the cleaning efficiency and cleaning quality to a certain extent, its equipment occupies a large space and requires special construction and fixation, which not only increases the difficulty and cost of installation, but also limits the mobility and flexibility of the cleaning equipment. More importantly, the automatic cleaning equipment often uses a huge amount of water during the cleaning process, which not only causes a waste of water resources, but also increases the cleaning cost. At the same time, the one-time investment of the automatic cleaning equipment is large and the maintenance cost is high, which is a considerable economic burden for many cleaning service providers. In the long-term use process, the maintenance and maintenance of the equipment also requires a lot of manpower and material resources, further increasing the operating cost. In summary, the existing manual cleaning and automatic cleaning methods have many shortcomings and cannot meet the needs of modern cleaning operations for high efficiency, low cost, flexibility and diversity.

[0003] It is based on this background that the present invention proposes a semi-automatic mobile cleaning machine, which aims to achieve efficient, convenient and low-cost cleaning operations through innovative design and technical means to meet the urgent needs of the modern cleaning market.

[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] See also Figures 1 to 6 , a semi-automatic mobile cleaning machine, characterized in that it includes: a body driving device 1, used to drive the cleaning machine to move; a car body shell 2, installed above the car body driving device 1, used to protect internal components and provide a working environment, the car body shell 2 includes a main shell 201, a front door 202 and a heating system inspection door 203; a power control system 3, installed in the car body shell 2, used to control the overall operation of the cleaning machine; a water system 4, installed in the car body shell 2, used to supply and discharge water required for cleaning; a heating system 5, installed in the car body shell 2, connected to the water system 4, used to heat the cleaning water; a supporting structure 6, installed on the car body shell 2; a water spraying device 7, installed on the supporting structure 6, used to spray the cleaning water onto the surface to be cleaned in a specific manner; a cleaning rolling device 9, installed on the supporting structure 6, cooperated with the water spraying device 7, used to roll and remove surface dirt during the cleaning process; a protective plate 8, installed on the supporting structure 6 at the back of the cleaning rolling device 9, used to protect the internal components of the cleaning machine and the operator from splashes or debris that may be generated during the cleaning process.

[0025] The semi-automatic mobile cleaning machine realizes efficient and flexible cleaning operations by integrating key components such as a vehicle body drive device 1, a vehicle body shell 2, a power control system 3, a water system 4, a heating system 5, a support structure 6, a water spray device 7, a cleaning rolling device 9 and a protective plate 8. The vehicle body drive device 1 ensures that the cleaning machine can move freely in different working environments and improves the operation coverage; the vehicle body shell 2 provides solid protection for the internal components and ensures the stability and durability of the equipment; the power control system 3 realizes precise control of various functions of the cleaning machine and improves the degree of automation and convenience of operation; the water system 4 and the heating system 5 jointly ensure the stable supply and suitable temperature of water during the cleaning process and improve the cleaning efficiency and quality; the support structure 6 provides a stable support for the water spray device 7 and the cleaning rolling device 9 to ensure the stability and accuracy of the cleaning operation; the coordinated use of the water spray device 7 and the cleaning rolling device 9 realizes comprehensive and efficient cleaning of the surface to be cleaned; the protective plate 8 effectively protects the internal components and operators of the cleaning machine and improves the safety of the operation.

[0026] The vehicle body driving device 1 includes: a vehicle body base 101, which serves as the basic supporting structure of the cleaning machine; a control handle 102, which is connected to a driving wheel 103 through a handle connector 105, and is used to receive instructions from an operator and control the movement and steering of the cleaning machine; the driving wheel 103, which is installed below the vehicle body base 101 and can drive the cleaning machine forward, backward or stop according to the instructions of the control handle 102; and directional wheels 104, which are arranged in two groups and installed below the vehicle body base 101, and cooperate with the driving wheel 103 to ensure the stability and directionality of the cleaning machine during the movement.

[0027] The working principle of the vehicle body drive device is as follows: the vehicle body drive device 1 is a key part for the semi-automatic mobile cleaning machine to achieve flexible movement. The vehicle body base 101, as the basic supporting structure of the cleaning machine, bears the entire weight and various components of the cleaning machine, ensuring the stability and durability of the cleaning machine. The design of the control handle 102 enables the operator to conveniently control the movement and steering of the cleaning machine, improving the flexibility and convenience of the cleaning operation. When the operator presses the corresponding button on the control handle 102, the command is transmitted to the driving wheel 103 through the handle connector 105. The driving wheel 103 generates a driving force through the internal motor and transmission mechanism according to the received command to drive the cleaning machine forward, backward or stop. At the same time, the directional walking wheel 104 cooperates with the driving walking wheel 103 to ensure the stability and directionality of the cleaning machine during the walking process. The setting of the directional walking wheel 104 enables the cleaning machine to maintain a stable driving track and remain stable even on uneven ground. The design of this vehicle body drive device 1 not only realizes the flexible movement of the cleaning machine, but also ensures the stability and safety during the cleaning operation. The operator can easily adjust the walking speed and direction of the cleaning machine according to actual needs by controlling the handle 102, so that the cleaning machine can adapt to various complex working environments and operation requirements. At the same time, the reliability and durability of the vehicle body drive device 1 also ensure that the cleaning machine can work for a long time and with high intensity, thereby improving the efficiency and quality of the cleaning operation.

[0028] The power control system 3 includes: a power battery 301, which serves as the main power source of the cleaning machine and provides the required electrical energy for various functions of the cleaning machine; an electrical component panel 302, which is installed in the vehicle body shell 2 and integrates the electrical components required to control various functions and actions of the cleaning machine; a button 303, which is set at a position convenient for the operator to reach, and is used to receive the operator's instructions and control the corresponding electrical components on the electrical component panel 302, so as to realize various functions and actions of the cleaning machine; a charging interface 304, which is connected to the power battery 301 and is used to charge the power battery 301.

[0029] The working principle of the power control system is as follows: the power control system 3 is the core part of the semi-automatic mobile cleaning machine, which ensures that the cleaning machine can operate stably and efficiently. As the main power source of the cleaning machine, the power battery 301 stores a large amount of electrical energy and provides continuous and stable power support for various functions of the cleaning machine. The electrical component matching plate 302 integrates the electrical components required to control various functions and actions of the cleaning machine, including switches, relays, sensors, etc., which are connected through complex circuits to achieve precise control of various functions of the cleaning machine. The operator sends instructions to the power control system 3 through the button 303. After receiving the instruction, the button 303 transmits the signal to the corresponding electrical components on the electrical component matching plate 302. These electrical components control various functions and actions of the cleaning machine according to the preset logical relationship, such as starting the water pump, adjusting the water spray pressure, and controlling the rotation of the cleaning rolling device. This operation method is simple and intuitive, which greatly improves the efficiency and convenience of the cleaning operation. At the same time, the design of the charging interface 304 enables the power battery 301 to be easily charged. When the power battery 301 is low on power, the operator only needs to connect the charging interface 304 to the charging device to charge the power battery 301. This ensures that the cleaning machine can work continuously and stably, avoiding operation interruption due to low power.

[0030] The water system 4 includes a stainless steel water tank 401 which is firmly mounted at the lower part of the vehicle body shell 2 and is closely connected to the vehicle body base 101 as a storage container for cleaning water. A water level gauge 402 is mounted on the water tank 401, which can display the water level in the water tank in real time, so that the operator can intuitively understand the water volume and replenish the water source in time when needed. A water pump 403 is arranged on the outside of the water tank 401, and its water inlet is controlled by a water pump inlet valve 405. When the cleaning operation starts, the operator will open the water pump inlet valve 405 to allow the water pump 403 to absorb water from the water tank 401. An impeller is installed inside the water pump 403, which generates a strong suction force through the rotation of the impeller, sucks the water in the water tank and pressurizes it to the water spray device 7 through the water pipe 404. The water pipe 404 serves as a water transmission channel to ensure that the water can reach the water spray device 7 smoothly and efficiently to meet the water pressure and flow requirements of the cleaning operation. The precise control of the water pump inlet valve 405 is the key to achieving water supply on demand. When the cleaning operation is suspended or ended, the operator will close the water pump inlet valve 405, thereby cutting off the water inlet channel of the water pump 403 to avoid wasting water resources. This design enables the water system 4 to flexibly adjust the water supply according to the actual needs of the cleaning operation. In addition, the water tank drain valve 406 is arranged at the bottom or side of the water tank 401, which is used to discharge the water in the water tank when needed, such as when cleaning or repairing the water tank. The water tank water inlet 407 is connected to the water tank 401 through a pipeline for adding water to the water tank. A pipe cap 408 is provided on the water inlet to ensure the sealing of the water tank and prevent water leakage. In summary, the water system 4 realizes the effective storage, management, transportation and utilization of water in the cleaning process through the coordinated work of the stainless steel water tank 401, the water level gauge 402, the water pump 403, the water pipe 404, the water pump inlet valve 405, the water tank drain valve 406, the water tank water inlet 407 and the pipe cap 408. This system not only ensures the continuity and efficiency of cleaning operations, but also improves the utilization efficiency of water resources through precise water volume control and water resource management.

[0031] The heating system 5 is an important part for adjusting the water temperature in the semi-automatic mobile cleaning machine. The technical effects brought by its detailed composition and working principle are as follows: the heating rod 501 is cleverly installed on the side of the stainless steel water tank 401 and is closely connected to the power control system 3. This design enables the working state of the heating rod 501 to be completely and accurately controlled by the power control system 3. When the cleaning operation has specific requirements for the water temperature, the power control system 3 will start the heating rod 501 to start working. The heating rod 501 is equipped with a heating element, which quickly heats the water inside the water tank 401 by converting electrical energy into thermal energy to ensure that the water temperature can meet the needs of the cleaning operation. The liquid level switch 502 is installed on the top of the water tank 401. Its main function is to detect the liquid level height in the water tank in real time. This function is crucial for the heating system because the height of the water level will directly affect the working efficiency and safety of the heating rod 501. If the water level is too low, the heating rod 501 may be damaged due to dry burning; if the water level is too high, it may cause safety hazards due to water splashing. Therefore, the accurate detection of the liquid level switch 502 provides a reliable safety guarantee for the heating system. The heating system 5 realizes the accurate control and adjustment of the water temperature through the coordinated work of the heating rod 501 and the liquid level switch 502, and meets the diverse requirements of the water temperature for the cleaning operation. At the same time, this system also ensures the safety and stability of the heating process through the real-time monitoring function of the liquid level switch 502. This design not only improves the efficiency and quality of the cleaning operation, but also extends the service life of the heating system 5 and reduces the maintenance cost. Therefore, the heating system 5 plays a vital role in the semi-automatic mobile cleaning machine.

[0032] The support structure 6 is a key component in the semi-automatic mobile cleaning machine to ensure the stability and functionality of the equipment. The technical effects brought by its detailed composition and working principle are as follows: the columns 601 are firmly arranged on the left and right sides of the car body shell 2, respectively. They serve as the main supporting points of the support structure 6 and provide a solid supporting foundation for the entire equipment. This design not only enhances the stability of the equipment, but also ensures the safety of the equipment during movement and operation. The rear mounting column 602 is arranged at the rear of the car body shell 2 and is closely connected to the column 601 through the connecting bent plate 603. This design not only strengthens the overall rigidity of the support structure 6, but also makes the entire support structure more compact and stable. The connecting bent plate 603 is used as a connecting piece. Its precise processing and installation ensure the firm connection between the column 601, the rear mounting column 602, and the protective plate 8, and improves the overall impact resistance of the equipment. The upper connecting plate 604 is arranged on the top of the support structure 6. It serves as the connection and fixing point of the water spray device 7 and the protective plate 8, and plays a vital role. The flatness and strength of the upper connecting plate 604 have been strictly designed and controlled to ensure that the water spray device 7 can be stably installed thereon and maintain a stable posture during operation. This design not only improves the efficiency and quality of the cleaning operation, but also extends the service life of the water spray device 7. In summary, the support structure 6 achieves stable support and precise connection of various components of the semi-automatic mobile cleaning machine through the coordinated work of the column 601, the rear mounting column 602, the connecting bent plate 603 and the upper connecting plate 604. This design not only improves the stability and safety of the equipment, but also ensures the efficient conduct of the cleaning operation.

[0033] The water spray device 7 is the core executive component of the semi-automatic mobile cleaning machine. The technical effects brought by its detailed structure and working principle are as follows: the water spray pipe 701, as the main component of the water spray device 7, is closely connected to the water pump outlet pipe of the water system 4 through a pipeline. This design ensures that the water sent by the water pump can flow smoothly into the water spray pipe 701, providing a stable water source for the subsequent water spraying operation. On the water spray pipe 701, several water spray nozzles 702 are carefully installed and facing the surface to be cleaned. The design of these water spray nozzles 702 takes into account the cleaning efficiency and cleaning effect. They can spray the water sent by the water pump at a certain pressure and angle. When the water pump is started and delivers water, the water flows through the water spray pipe 701 to each water spray nozzle 702, and then sprays onto the surface to be cleaned in the form of high-speed, high-pressure water flow. This spraying method can not only effectively remove dirt and impurities on the surface, but also can achieve comprehensive and uniform cleaning of surfaces to be cleaned of different shapes and materials by adjusting the angle and number of water spray nozzles 702. The working principle of the water spray device 7 embodies the cleaning concept of high efficiency and energy saving. By precisely controlling the water outlet pressure of the water pump and the design of the water spray nozzle 702, the water spray device 7 can save water resources and energy to the maximum extent while ensuring the cleaning effect. In addition, the direction and angle adjustability of the water spray nozzle 702 enable the water spray device 7 to adapt to the needs of different cleaning scenarios, thereby improving the versatility and flexibility of the device.

[0034] The cleaning rolling device 9 is a key component for realizing the cleaning function in the semi-automatic mobile cleaning machine. The technical effects brought by its detailed composition and working principle, combined with the role of the supporting structure 6, can be described as follows: the drum drive 901 is used as the power source of the cleaning rolling device 9, and is equipped with an efficient driving motor. When the motor is started, it provides sufficient rotational power for the drum drive 901, so that it can rotate smoothly and continuously. This rotation action is the basis for the operation of the cleaning rolling device 9. It drives the porous rubber sheet 902 with nylon threads installed on the outer surface of the drum drive 901 to rotate together, thereby realizing the physical friction and cleaning effect on the surface to be cleaned. The porous rubber sheet 902 with nylon threads is a component in the cleaning rolling device 9 that directly contacts the surface to be cleaned. Its design takes into account both the cleaning effect and the protection of the surface to be cleaned. The porous structure enables the rubber sheet to better absorb and carry moisture during the rotation process, while the nylon threads enhance the cleaning ability and wear resistance of the rubber sheet. When the roller drive 901 rotates, these rubber sheets are like countless small brushes, constantly scrubbing the cleaned surface and effectively removing dirt and impurities. The upper connecting piece 903 tightly connects the cleaning rolling device 9 to the supporting structure 6. This design not only ensures the stability of the cleaning rolling device 9 during operation, but also makes the entire cleaning machine more compact and reasonable in structure. The supporting structure 6 provides the necessary support and fixation for the cleaning rolling device 9, so that the cleaning rolling device 9 can maintain a stable posture and efficient cleaning effect under various operating environments. The lower connecting plate 904 is fixed to the bottom of the vehicle body base 101, providing another stable support point for the cleaning rolling device 9. This design further enhances the stability and reliability of the cleaning rolling device 9, so that it can always maintain a stable rotation and cleaning action during operation.

[0035] The upper connecting member (903) is provided with a long slot hole 907; the technical effect brought by this design, combined with the function of the support structure 6, can be described as follows: Enhanced cleaning effect: By adjusting the tilt angle of the roller drive 901 through the long slot hole 907, the porous rubber sheet 902 with nylon threads can be more closely fitted to the surface to be cleaned. This improved fit helps to enhance the cleaning effect and makes it easier to remove dirt and impurities. Adapt to different cleaning scenarios: Different cleaning scenarios have different requirements for the cleaning rolling device 9. The design of the long slot hole 907 enables the roller drive 901 to adjust the tilt angle according to actual needs, thereby adapting to different cleaning surfaces and cleaning needs. This flexibility improves the versatility and practicality of the cleaning rolling device 9. Optimize the force of the support structure: When the roller drive 901 tilts forward, the support structure 6 needs to withstand forces of different directions and sizes. Reasonable support structure design can ensure that these forces are effectively dispersed and transmitted, thereby avoiding local stress concentration and structural damage. The design of the long slot hole 907 makes the tilt angle of the drum drive 901 adjustable, which helps to optimize the stress of the supporting structure and improve the stability and durability of the entire cleaning machine. Improved operational convenience: The long slot hole 907 allows the operator to easily adjust the tilt angle of the drum drive 901 without complicated disassembly and reassembly. This design improves the operational convenience of the cleaning machine and reduces the difficulty and time cost of operation.

[0036] The rubber sheet 905 and the stainless steel tray 906 installed on the bottom side of the porous rubber sheet 902 with nylon threads are the key designs to ensure safe and stable operation in the cleaning rolling device 9. The working principle of this design and the technical effects it brings, combined with the role of the supporting structure, can be elaborated in detail as follows: Prevent nylon threads from being rolled into the gap: During the rotation of the drum, the porous rubber sheet 902 with nylon threads will continuously contact and generate friction with the surface to be cleaned. If there are no effective protective measures, the nylon threads may be rolled into the gap between the drum and the vehicle body base 101 due to friction or external force, resulting in equipment damage or nylon thread breakage. The installation of the rubber sheet 905 and the stainless steel tray 906 effectively prevents this from happening. They form a physical barrier to ensure that the nylon threads will not be rolled into the gap. Protect the drum and the base: The rubber sheet 905 has good elasticity and wear resistance. It can produce slight contact with the vehicle body base 101 when the drum rotates, thereby playing a role in buffering and reducing wear. This helps to extend the service life of the drum and the base and reduce wear and noise caused by friction. The stainless steel tray 906 provides more solid support and protection. Its rigidity and corrosion resistance ensure that the nylon thread does not directly contact the base even in harsh cleaning environments, thereby avoiding equipment damage caused by corrosion or wear. Optimizing the cleaning effect: The installation of the rubber sheet 905 and the stainless steel tray 906 also helps to optimize the cleaning effect. They ensure that the porous rubber sheet 902 with nylon threads can always remain in a stable position and will not be offset or deformed due to external forces. This allows the nylon threads to be more evenly distributed on the surface to be cleaned, improving the coverage and efficiency of the cleaning. Enhance the stability of the support structure: The rubber sheet 905 and the stainless steel tray 906 are part of the cleaning rolling device 9 and are closely connected to the support structure 6. Their presence enhances the overall stability of the support structure, allowing the drum to run more smoothly during rotation and reducing noise and wear caused by vibration or shaking.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
