[0032] An entrance control device 40 is installed at the entrance of the entrance channel 11 or at one end of the external channel 20 near the entrance of the entrance channel 11, and is used to detect the situation inside the entrance channel 11 and control the opening and closing of the entrance channel 11.

[0033] An exit control device 50 is installed at the exit of the removal channel 12 to monitor the situation inside the removal channel 12 and control the opening and closing of the removal channel 12.

[0034] A guiding device 60 is provided in at least one of the entry channel 11, the exit channel 12 and the car wash space 10 for guiding the travel trajectory of vehicles and / or the spacing between multiple vehicles;

[0035] The central control unit 70 is electrically connected to the car wash unit 30, the entrance control unit 40, and the exit control unit 50, respectively.

[0037] This invention, through the coordinated operation of an entrance control device 40 and an exit control device 50, ensures efficient management of vehicles within the car wash space 10, the entry channel 11, and the exit channel 12. This guarantees controllable car wash sequence and prevents collisions between washed vehicles and vehicles or personnel in the external channel 20, effectively improving the safety and orderliness of the car wash process. Furthermore, the guiding device 60 effectively guides the vehicle's trajectory and / or the spacing between multiple vehicles, thus preventing rear-end collisions or other accidents. The coal mine underground car wash system proposed in this invention achieves efficient washing of multiple vehicles underground, through a central... The highly efficient and intelligent control of the control device 70 enables full monitoring and control of each process in the car washing operation, effectively replacing on-site personnel command, reducing operational risks, eliminating safety hazards, and saving manpower. After practical use of the coal mine underground car washing system proposed in this invention, it was found that compared with the traditional manual car washing process, using this system saves at least 2 man-days per shift, reducing personnel by 180 person-times per month, resulting in significant economic and manpower savings, making it suitable for large-scale promotion and use. The coal mine underground car washing system proposed in this invention can not only be used for car washing operations in coal mines but can also be extended to car washing operations in relatively small areas on the ground.

[0038] It should be noted that, in a specific embodiment of the present invention, the car wash space 10, the entry passage 11, and the exit passage 12 can be formed underground in a coal mine by excavation or by utilizing existing roadways or chambers.

[0039] like Figure 1 As shown, the entrance control device 40 includes: a camera 41, electrically connected to the central control device 70, used to detect the situation inside the entrance channel 11; a first indicator light 42, set at the entrance of the entrance channel 11 or at one end of the external channel 20 near the entrance of the entrance channel 11; the first indicator light 42 is electrically connected to the central control device 70; the first indicator light 42 allows or prevents vehicles from entering the entrance channel 11 by changing different colored lights.

[0040] By setting up camera 41, real-time monitoring of the situation inside the entrance channel 11 is achieved; by setting up first indicator light 42, orderly control of vehicles entering the entrance channel 11 is achieved.

[0041] It is worth noting that, in one specific embodiment of the present invention, the camera 41 is not limited to being installed in the entry channel 11, but can also be installed in the car wash space 10, the exit channel 12, and the external channel 20 (e.g., Figure 2 (as shown), to ensure the comprehensiveness of the data collected by the central control device 70; the first indicator light 42 can be a common traffic light device, which is convenient for procurement and personnel identification and use.

[0042] like Figure 1 As shown, the entrance control device 40 further includes: a first laser fence 43, which is disposed at the entrance of the entrance channel 11 and electrically connected to the central control device 70; the first laser fence 43 forms a virtual fence by emitting laser light, and the virtual fence stops at the entrance channel 11 to control the opening and closing of the entrance channel 11; and / or, the color of the virtual fence is variable, and the opening and closing of the entrance channel 11 is guided by different color changes; an infrared sensor 44, disposed at the entrance of the entrance channel 11 and electrically connected to the central control device 70; the infrared sensor 44 is used to detect the passage of vehicles; a display screen 45, disposed at the entrance of the entrance channel 11 or disposed at one end of the external channel 20 near the entrance of the entrance channel 11; the display screen 45 is electrically connected to the central control device 70; the display screen 45 is used to display at least one internal view of the entrance channel 11, the exit channel 12 and the car wash space 10, so that the driver of the vehicle can know real-time information; and / or, the display screen 45 is used to display information signs indicating that entry is prohibited or permitted, so as to guide the driver to operate the vehicle. This configuration ensures that the entrance control device 40 has the functions of controlling passage, automatic detection, and real-time display.

[0043] In one specific embodiment of the present invention, the signal of the camera 41 is transmitted to the central control device 70, and the display screen 45 displays the real-time image inside the car wash space 10 (car wash point) so that the driver can watch the situation inside the car wash point. When the car wash point is vacant, the first indicator light 42 displays a green light, the display screen 45 displays "Turn right to enter the car wash point", and the first laser fence 43 changes from red to green laser. Under this condition, the vehicle can enter the entrance channel 11.

[0044] like Figure 1 As shown, the exit control device 50 includes: a second indicator light 51, installed at the exit of the exit channel 12 or inside the external channel 20; the second indicator light 51 is electrically connected to the central control device 70; the second indicator light 51 guides the opening and closing of the exit channel 12 by changing different colors of light, so as to allow or prevent vehicles from leaving the exit channel 12; a second laser fence 52, installed at the exit of the exit channel 12 and electrically connected to the central control device 70; the second laser fence 52 forms a virtual fence by emitting laser light, the virtual fence stops the exit channel 12, and controls the opening and closing of the exit channel 12; and / or, the color of the virtual fence is variable, and the opening and closing of the exit channel 12 is guided by changing different colors. This configuration ensures both the simplicity of the structure of the exit control device 50 and the function of controlling passage.

[0045] In one specific embodiment of the present invention, the entrance control device 40 and the exit control device 50 have the same structure to facilitate subsequent procurement and unified maintenance.

[0046] like Figure 1 and Figure 2 As shown, the guiding device 60 includes reflective guide lines 61 and multiple vehicle distance indicators 62. The reflective guide lines 61 are continuously arranged along the extension direction of the entry channel 11, the car wash space 10 and the exit channel 12 to guide vehicles to drive along the reflective guide lines 61. The multiple vehicle distance indicators 62 are provided at least in one of the entry channel 11, the exit channel 12 and the car wash space 10, and are equidistant along the extension direction to guide the spacing between multiple vehicles.

[0047] By setting up reflective guide lines 61, vehicles are effectively guided to drive along the reflective guide lines 61 in relatively dark alleyways, thereby avoiding vehicles from hitting the inner wall of the alleyway, improving safety, and preventing vehicles from deviating or getting lost; by setting up multiple vehicle distance signs 62, the distance between multiple vehicles is effectively guided, thereby preventing rear-end collisions.

[0048] like Figure 1 and Figure 2 As shown, there are at least two reflective guide lines 61, including a first guide line 611 and a second guide line 612. The first guide line 611 and the second guide line 612 are set parallel to each other on the ground, and the area between them forms a driving area along which vehicles travel. Multiple vehicle distance indicators 62 are arranged at intervals along the extension direction of the entry passage 11, the car wash space 10, and the exit passage 12, and are set on the side walls of the entry passage 11, the car wash space 10, and the exit passage 12. This arrangement further improves the safety of vehicle driving.

[0049] like Figure 1 and Figure 2 As shown, the car wash device 30 includes an explosion-proof car wash machine 31, a sedimentation tank 32, and a drainage assembly 33. The explosion-proof car wash machine 31 is installed within the car wash space 10 and is used for automatic vehicle washing. The explosion-proof car wash machine 31 and the drainage assembly 33 are electrically connected to the central control device 70. Figure 3 As shown, the sedimentation tank 32 is installed on the ground of the car wash space 10 to collect wastewater generated by the explosion-proof car wash machine 31 during vehicle washing. The drainage component 33 is connected to the sedimentation tank 32 to discharge the wastewater from the sedimentation tank 32. This design ensures both the operational reliability of the car wash device 30 and a simplified structure, thereby effectively reducing costs.

[0050] Specifically, there are multiple explosion-proof car wash machines 31, which are spaced apart; the sedimentation tank 32 is located at the lowest point on the ground, and the sedimentation tank 32 has side walls on its circumference for draining wastewater, the side walls are connected to the ground, and the slope of the side walls is not less than three per thousand; the drainage component 33 includes a filter screen 331, a pipe 332, and an explosion-proof water pump 333, the filter screen 331 is installed at the inlet of the pipe 332; the inlet of the pipe 332 is connected to the sedimentation tank 32; the pipe 332 is connected to the explosion-proof water pump 333, and the explosion-proof water pump 333 is used to drive the liquid flow in the pipe 332 to discharge the wastewater in the sedimentation tank 32.

[0051] By setting up multiple explosion-proof car wash machines 31, the car washing efficiency is improved; by setting up a sedimentation tank 32 with sidewalls on all sides for diverting wastewater, the sidewalls are connected to the ground and the slope of the sidewalls is not less than three per thousand, ensuring the collection effect of wastewater in the sedimentation tank and preventing wastewater leakage.

[0052] It is worth noting that the explosion-proof car wash machine 31 can be installed in the underground chamber of a coal mine and can automatically complete the car wash process such as spraying water, wiping, and drying; the pipeline 332 is connected to the explosion-proof water pump 333 and is suspended on the top plate of the chamber.

[0053] like Figure 1 and Figure 2 As shown, the car wash device 30 also includes at least two laser pointers, each electrically connected to the central control unit 70. The at least two laser pointers include a first pointer 34 and a second pointer 35. The first pointer 34 is located at the entrance of the explosion-proof car wash machine 31, and the second pointer 35 is located at the exit of the explosion-proof car wash machine 31. When the first pointer 34 detects a vehicle entering the explosion-proof car wash machine 31, it changes color via laser light to prevent the next vehicle from entering. When the second pointer 35 detects a vehicle leaving the explosion-proof car wash machine 31, the central control unit 70 controls the first pointer 34 to change color again, allowing the next vehicle to enter the explosion-proof car wash machine 31. By setting the first pointer 34 and the second pointer 35, the safe operation of the explosion-proof car wash machine 31 is achieved.

[0054] In one specific embodiment of the present invention, the central control device 70 includes cables, a computer, and multiple PLC cabinets, etc. The computer is electrically connected to each component through cables to ensure reliable connection.

[0055] The present invention also provides a car washing method, applied to the above-mentioned underground car washing system in a coal mine. The car washing method includes the following steps: entrance sorting step: controlling multiple vehicles to enter the car washing space 10 sequentially from the entrance channel 11; washing step: washing the vehicles; exit control step: controlling the washed vehicles, controlling multiple washed vehicles to drive out sequentially from the exit channel 12, and controlling the washed vehicles to avoid vehicles or pedestrians in the external channel 20.

[0056] By setting up entry sorting steps and exit control steps, efficient management of vehicles in the car wash space 10, entry channel 11 and exit channel 12 is ensured. This not only ensures the controllability of the car wash sequence, but also avoids safety accidents such as collisions between washed vehicles and vehicles or people in the external channel 20, effectively improving the safety and orderliness of the car wash.

[0057] Specifically, the car wash method also includes: a drainage step: draining wastewater generated during washing within the car wash space 10; and an alarm step: if any abnormality is detected in the entrance sorting step, washing step, exit control step, or drainage step, a remote wireless alarm and / or voice alarm is triggered, and multiple vehicles are controlled to stop moving or orderly evacuate from the entrance channel 11, exit channel 12, and car wash space 10. By setting up the alarm step, the safety of the car wash process is ensured.

[0058] In summary, this invention provides a coal mine underground vehicle washing system and method. By coordinating the entry control device 40 and exit control device 50, this invention ensures efficient control of vehicles within the washing space 10, entry channel 11, and exit channel 12. This guarantees controllable washing sequence and prevents collisions between washed vehicles and vehicles or personnel in the external channel 20, effectively improving the safety and orderliness of the washing process. Furthermore, the guiding device 60 effectively guides the vehicle's trajectory and / or the spacing between multiple vehicles, thus preventing rear-end collisions or other accidents. The coal mine underground vehicle washing system proposed in this invention achieves… The efficient underground vehicle washing system utilizes a central control device 70 for intelligent control, enabling full monitoring and control of each washing process. This effectively replaces on-site personnel command, reduces operational risks, eliminates safety hazards, and saves manpower. Practical use of the coal mine underground vehicle washing system proposed in this invention has shown that compared to traditional manual command, it saves at least 2 man-days per shift, reducing manpower by 180 person-times per month. The economic and manpower savings are significant, making it suitable for large-scale deployment.
