Description

Technical Field

[0001] The present invention belongs to the technical field of car washing equipment, and particularly relates to an automatic car washing machine for cleaning the interior of a car compartment. Background Art

[0002] In the car washing industry, traditional car washing machines have long focused on the external cleaning of cars. The cleaning of the interior of the car compartment mainly relies on manual operation. The common method is for workers to enter the car compartment and hold a spray gun for cleaning. This mode has many serious drawbacks: In terms of efficiency, taking a freight car as an example, its car compartment has a large space and a wide loading area. Workers need to hold a spray gun to carefully scrub each part, and the process is complicated and time-consuming. It often takes several hours to clean the interior of an ordinary van, which greatly restricts the overall efficiency and throughput of the car washing business, resulting in a limited number of vehicles serviced per unit time in the car wash and a long waiting time for customers, affecting the experience. In terms of labor intensity, this is a heavy physical labor. Workers hold the spray gun for a long time and bear the recoil force, and move around in an uncomfortable position in the car compartment among the cargo residues and complex structures, which is extremely easy to cause physical fatigue. Safety hazards cannot be ignored. The environment in the car compartment is complex, and there may be sharp objects and chemical substances remaining. Workers are at risk of being scratched and poisoned. When the ventilation is poor, the water vapor and the volatile gas of the cleaning agent accumulate, endangering the health of workers. When cleaning at a high place, there is also a risk of falling. In terms of cleaning quality, the differences in manual operations lead to uneven effects. Different workers have different techniques, forces, and degrees of concentration, making it difficult to unify the cleaning effect of the interior of the car compartment. Many corners are easily overlooked. In addition, due to the diverse types of goods transported by freight cars, the types of stains on the car compartment are diverse, and it is difficult for manual labor to accurately clean according to the characteristics of the stains, increasing the difficulty and complexity of ensuring high-quality cleaning effects. At the same time, the internal space structure of the car compartment is extremely complex. The car compartment sizes, shapes, and internal layouts of different vehicle models vary greatly, bringing many obstacles to the research and development of automatic cleaning equipment. The car compartment of a van is long and open, and there may be multi-layer shelves or rope hooks inside, increasing the cleaning dead corners. The car compartment of a small closed freight car is narrow and compact, making it difficult for the cleaning equipment to be deployed. Special-purpose vehicles such as refrigerated trucks have unique internal structures and materials. Not only the cleaning effect needs to be ensured, but also the impact on the refrigeration equipment and the heat preservation performance of the car compartment needs to be considered.

[0016] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0017] Please refer to Figures 1-5 , the present invention provides the following technical solutions: An automatic car wash machine for cleaning the interior of a carriage, including a nozzle 1 and a water pump (the water pump is a known prior art product and is not shown in the figure). The nozzle 1 is connected to the water pump through a pipeline. The nozzle 1 is connected with an automatic cleaning device. The automatic cleaning device includes a telescopic arm 2. The nozzle 1 is connected to the end of the telescopic arm 2. A controller (the controller is a known prior art product and is not shown in the figure) is arranged near the telescopic arm 2. The controller is connected to the telescopic arm 2 through a wire or a wireless communication module.

[0018] With the above structure, the operator can remotely control the movement of the telescopic arm 2 with the help of the controller, and then accurately adjust the position of the nozzle 1, without the need for manual operation close to the carriage. This not only improves the operation safety but also greatly improves the flexibility of the cleaning operation, enabling the nozzle 1 to quickly reach any area to be cleaned inside the carriage, significantly improving the cleaning efficiency.

[0019] In this embodiment, the automatic cleaning device further includes a lifting platform 3. The telescopic arm 2 includes a fixed end 4 and a movable end 5. The fixed end 4 is connected to the tabletop of the lifting platform 3. The lifting platform 3 is connected to the controller through a wire or a wireless communication module.

[0020] With the above structure, the lifting platform 3 can be flexibly lifted under the control of the controller, and can quickly and accurately adjust the height of the telescopic arm 2 and the nozzle 1 according to the height of different carriages, ensuring that the car wash machine is applicable to various carriages with different heights, expanding the application range of the equipment, and avoiding the situation of incomplete cleaning due to the height difference of the carriages.

[0021] In this embodiment, a proximity sensor 6 is provided at the movable end 5, and the proximity sensor 6 is connected to the controller through a wire or a wireless communication module.

[0022] With the above structure, the proximity sensor 6 can monitor the distance between the movable end 5 of the telescopic arm 2 and the internal structure of the carriage in real time, and promptly feedback the data to the controller. When the distance is too close, the controller quickly adjusts the movement of the telescopic arm 2, effectively preventing the telescopic arm 2 and the nozzle 1 from colliding with the internal structure of the carriage, protecting the car wash equipment, reducing the risk of equipment damage, and at the same time ensuring the smooth progress of the cleaning process and avoiding cleaning interruption caused by collisions.

[0023] In this embodiment, the nozzle 1 is a rotary nozzle 1.

[0024] With the above structure, under the action of the high-pressure water flow and the cleaning medium mixture, the rotary nozzle 1 can rotate at a high speed and spray the mixture in a multi-angle and all-round manner onto the interior of the carriage. Compared with ordinary fixed nozzles 1, the rotary nozzle 1 greatly increases the cleaning coverage area, can clean every corner of the interior of the carriage more thoroughly, effectively improves the cleaning quality, and reduces the cleaning blind area.

[0025] In this embodiment, the controller is connected to a human-machine interaction screen (the human-machine interaction screen is a well-known prior art product and is not shown in the figure).

[0026] With the above structure, the operator can conveniently input cleaning instructions through the human-machine interaction screen, such as setting the cleaning mode, adjusting the movement parameters of the telescopic arm 2 and the lifting platform 3, etc. The human-machine interaction screen can also display the working status, fault information, etc. of the car wash in real time, greatly optimizing the operator's use experience, reducing the operation difficulty, facilitating the operator to flexibly adjust the working parameters of the car wash according to the actual situation, and being able to promptly master the equipment operation status, which is convenient for equipment maintenance and fault troubleshooting.

[0027] In this embodiment, the water pump includes a water inlet and a water outlet. The water inlet is connected to the nozzle 1 through a pipeline, the water outlet is connected to a multi-way solenoid valve (the multi-way solenoid valve is a well-known prior art product and is not shown in the figure), and the multi-way solenoid valve is connected to the controller through a wire or a wireless communication module.

[0028] With the above structure, the controller can control the multi-way solenoid valve to open different channels, so that the high-pressure water flow is mixed with the cleaning medium in different medium tanks and then flows to the nozzle 1, and can flexibly select the appropriate cleaning medium to be mixed with the high-pressure water flow according to the type of stains inside the carriage, realizing targeted cleaning, improving the cleaning effect, and meeting different cleaning requirements.

[0029] Working principle: After starting the automatic car wash machine for cleaning the interior of the carriage, the water pump pumps water from the water source through the water inlet and pressurizes it, and outputs high-pressure water flow through the water outlet. One end of the multi-way solenoid valve is connected to the water outlet of the water pump, and the other end is respectively connected to the medium tank for storing various special cleaning media (such as strong decontamination agents, disinfectants, etc.) and the water pipe through the pipeline. Under the precise control of the controller, according to the preset cleaning requirements, the corresponding channels are quickly opened, so that the high-pressure water flow and the selected cleaning medium are fully mixed in the pipeline and then flow to nozzle 1; at the same time, the automatic cleaning device starts to work. Since the heights of different carriages are different, the lifting platform 3 receives signals through the wire under the drive of the controller's instructions to complete the lifting action, and precisely adjusts the height of the telescopic arm 2 fixed on it and the nozzle 1 connected to the end of the telescopic arm 2 to adapt to various carriages. Immediately afterwards, the telescopic arm 2 extends or contracts according to the signal transmitted by the controller through the wire or the wireless communication module, flexibly changing the position of the nozzle 1 to help it penetrate into all corners of the interior of the carriage in all directions. The proximity sensor 6 at the movable end 5 of the telescopic arm 2 continuously feeds back the distance information detected from the interior structure of the carriage to the controller through the wire or the wireless communication module. Once it detects that the distance is too close, it immediately sends a signal to the controller, and the controller responds instantly to adjust the action of the telescopic arm 2 in time to avoid the nozzle 1 colliding with the carriage. After the mixed liquid of the high-pressure water flow and the cleaning medium reaches the rotating nozzle 1, the strong pressure causes the nozzle 1 to rotate at a high speed and spray the mixed liquid in all directions and cover the entire interior of the carriage. When the cleaning process is completed, the controller will, according to the preset program, command the lifting platform 3 to slowly fall back to the initial position, and the telescopic arm 2 contracts and resets synchronously. At the same time, the water pump stops working, and the multi-way solenoid valve closes, stopping the supply of the mixed liquid of the high-pressure water flow and the cleaning medium to the nozzle 1. The entire automatic cleaning device returns to its original position and waits for the next operation instruction.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
