The front end of the water filling mechanism has a filling port, which is connected to the water inlet of the high-speed rail water tank for water filling operation. The water filling mechanism is also equipped with a water full detection device, which is connected to the controller. When the water full detection device detects that the high-speed rail water tank is full, the controller drives the water filling mechanism to stop filling water.

[0006] Furthermore, the visual device is a camera.

The other end of the second folding arm is connected to one end of the third folding arm via a third connecting shaft. The other end of the third folding arm is provided with an adsorption device, which adsorbs and contacts the outer cover of the high-speed rail water tank, causing the outer cover of the high-speed rail water tank to slide along the dragging path, thereby realizing the opening and closing of the outer cover of the high-speed rail water tank.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The embodiments of this utility model will be further described below with reference to the accompanying drawings: like Figure 1 , Figure 2As shown, an automatic water filling device for high-speed rail includes a housing 1, a controller mounted on the housing 1, a vision device 2 mounted on the top of the housing 1, and a moving device 3 mounted on the bottom of the housing 1. The vision device 2 and the moving device 3 are respectively connected to the controller. The vision device 2 monitors the position of the high-speed rail water tank 10, and the moving device 3 moves the housing 1 to the high-speed rail water tank 10. Inside the housing 1, from top to bottom, there are an outer cover opening mechanism 4, an inner cover opening mechanism 5, and a water filling mechanism 6. The outer cover opening mechanism 4, the inner cover opening mechanism 5, and the water filling mechanism 6 are respectively connected to the controller. The outer cover opening mechanism 4 opens or closes the outer cover 7 of the high-speed rail water tank, and the inner cover opening mechanism 5 opens or closes the inner cover 8 of the high-speed rail water tank. The front end of the water filling mechanism 6 has a filling port 6-1, which is connected to the water filling port 9 of the high-speed rail water tank for water filling operations. The water filling mechanism 6 is also equipped with a full water detection device, which is connected to the controller. When the full water detection device detects that the high-speed rail water tank 10 is full, the controller drives the water filling mechanism 6 to stop filling water.

[0027] Specifically, such as Figure 3 As shown, the mobile device 3 provided in this embodiment uses the train carriage arrival sensor to initially locate the position of the high-speed rail water tank 10. The vision device 2 provided in this embodiment is a camera. After the high-speed rail arrives at the station and comes to a complete stop, the vision device 2 confirms the position of the water filling valve of the high-speed rail water tank 10. The tank body 1 moves left and right guided by the vision device 2. After confirming that it is in place, the water filling operation is performed. This embodiment uses both the train carriage arrival sensor and the vision device 2 for dual positioning to ensure accurate water filling position.

[0028] The controller drives the outer cover opening mechanism 4 to contact the outer cover 7 of the high-speed rail water tank along a pre-set drag path. Simultaneously, the adsorption device 4-4 is activated. After the adsorption device 4-4 detects the set value, the outer cover opening mechanism 4 opens the outer cover 7 of the high-speed rail water tank along the pre-set drag path and maintains this position. The controller then drives the inner cover opening mechanism 5, which, through the coordinated movement of the first rotating arm 5-1 and the second rotating arm 5-2, opens the inner cover 8 of the high-speed rail water tank and maintains this position. The vision device 2 takes a picture to accurately locate the water inlet 9 of the high-speed rail water tank. After positioning, the water filling mechanism 6 moves forward. Once in position, it performs the water filling operation. After the tank is full, the operation stops.

[0029] The outer cover opening mechanism 4 can have various structures, as long as it achieves the above-mentioned functions. Specifically, for example... Figure 4As shown, the outer cover opening mechanism 4 provided in this embodiment is a three-axis linkage mechanism, including a first folding arm 4-1, a second folding arm 4-2, and a third folding arm 4-3. One end of the first folding arm 4-1 is connected to the housing 1 via a first connecting shaft, and the other end of the first folding arm 4-1 is connected to one end of the second folding arm 4-2 via a second connecting shaft. The other end of the second folding arm 4-2 is connected to one end of the third folding arm 4-3 via a third connecting shaft. The other end of the third folding arm 4-3 is provided with an adsorption device 4-4, which adsorbs and contacts the outer cover 7 of the high-speed rail water tank, causing the outer cover 7 of the high-speed rail water tank to slide along the dragging path, thereby realizing the opening and closing of the outer cover 7 of the high-speed rail water tank. Figure 4 As shown, both the first folding arm 4-1 and the second folding arm 4-2 are elongated, with connecting holes located at both ends of the first folding arm 4-1 and the second folding arm 4-2. The third folding arm 4-3 is L-shaped, with connecting holes located at its vertical end, and the adsorption device 4-4 located at its horizontal end. Preferably, the adsorption device 4-4 provided in this embodiment uses a vacuum adsorption method. The outer cover opening mechanism 4 can also be operated by installing a robot quick-change tool on a six-axis collaborative robot.

[0030] The inner cover opening mechanism 5 can have various structures, as long as it achieves the above-mentioned functions. Specifically, for example... Figure 5 As shown, the inner cover opening mechanism 5 is a two-axis rotating mechanism, including a first rotating arm 5-1 and a second rotating arm 5-2. A first slider 5-4 is provided on the side of the first rotating arm 5-1, and the first slider 5-4 is slidably mounted on a first guide rail 5-5. One end of the second rotating arm 5-2 is connected to one end of the first rotating arm 5-1, and the other end of the second rotating arm 5-2 is provided with a flip-top rod 5-3, which is perpendicular to the second rotating arm 5-2. When the inner cover 8 of the high-speed rail water tank is opened, the first slider 5-4 slides along the first guide rail 5-5, the flip-top rod 5-3 contacts the bottom of the inner cover 8, the second rotating arm 5-2 rotates upward, and the inner cover 8 of the high-speed rail water tank flips up.

[0031] The water filling mechanism 6 can have various structures, as long as it achieves the above functions. Specifically, for example... Figure 6As shown, the water filling mechanism 6 includes a bracket 6-2, a filling port 6-1 located at one end of the bracket 6-2, and a cylinder 6-3 connected to the filling port 6-1. A second slider 6-4 is connected to the lower end of the bracket 6-2 and is slidably mounted on a second guide rail 6-5. A third slider 6-6 is located below the second guide rail 6-5 and is slidably mounted on a third guide rail 6-7. The second guide rail 6-5 and the third guide rail 6-7 are perpendicular to each other. During water filling, the second slider 6-4 slides forward along the second guide rail 6-5. Upon approaching the guide rail, the third slider 6-6 slides left and right along the third guide rail 6-7 to ensure that the filling port 6-1 is aligned with the water inlet 9. Once aligned, the cylinder 6-3 extends, and the filling port 6-1, through air expansion, holds the water inlet 9, initiating water filling. After the water is full, a full-water detection device sends information to the controller, which then drives the water pump 12 to stop the water filling operation. The water filling mechanism 6 can also perform water filling operations by changing the robot quick-change tool through a six-axis collaborative robot.

[0032] Specifically, such as Figure 7 As shown, the water full detection device includes a pressure sensor 11, which is connected to a signal acquisition card 13 to monitor the water pressure flowing into the high-speed rail water tank 10. The signal acquisition card 13 is connected to a controller. The pressure sensor 11 is connected to a water pump 12. Municipal water supply enters the water tank 14 and is connected to the water pump 12 through a check valve 15 to add water to the high-speed rail water tank 10. When the pressure sensor 11 detects that the water pressure is too high, the pressure sensor 11 sends the information to the controller, and the controller drives the water pump 12 to stop adding water.

[0033] The working principle of this utility model is as follows: The ground track uses a train carriage arrival sensor to initially locate the position of tank 1. After the high-speed train arrives at the station and comes to a complete stop, the vision device 2 confirms the position of the high-speed train water tank 10. The moving device 3 moves tank 1 to the water-filling position. The outer cover opening mechanism 4, following a pre-set dragging path, contacts the outer cover 7 of the high-speed train water tank. Simultaneously, the suction vacuum is activated. After the suction device 4-4 detects the set value, the outer cover opening mechanism 4 opens the outer cover 7 of the high-speed train water tank according to the pre-set dragging path and holds the position. The inner cover opening mechanism 5, through the coordinated movement of the horizontal and rotary axes, opens the inner cover 8 of the high-speed train water tank and holds the position. The vision device 2 takes a picture to accurately locate the water inlet 9 of the high-speed train water tank. After positioning, the water filling mechanism 6 moves forward. After reaching the position, the cylinder 6-3 extends, and the filling port 6-1, through the principle of air expansion, holds the water inlet 9 of the high-speed train water tank. Water filling begins. After the water is full, the water full detection device sends information to the controller, and the controller drives the water pump 12 to stop the water filling operation. The filling port 6-1 is released, the cylinder 6-3 retracts, and the water filling mechanism 6 returns to its initial position. The inner cover opening mechanism 5 returns to its original position, and the inner cover 8 of the high-speed rail water tank at the water filling port 9 automatically closes under the action of the spring. The outer cover opening mechanism 4 closes the outer cover 7 of the high-speed rail water tank according to the pre-set dragging path and returns to its initial position.

[0034] The advantages and positive effects of this utility model are: This invention features a simple structure and convenient operation. The ground track uses a train carriage arrival sensor to initially position the tank. After the high-speed train arrives at the station and comes to a complete stop, a vision device confirms the position of the high-speed train water tank 10, and a moving device moves the tank to the water-filling position. The outer cover of the high-speed train water tank is opened and closed via an outer cover opening mechanism, and the inner cover is opened and closed via an inner cover opening mechanism. Water is automatically added via a water-filling mechanism, and water filling automatically stops once a full water detection device detects that the high-speed train water tank 10 is full. This invention requires no manual operation, has a high degree of automation, and automatically adds water instead of manually, reducing labor costs and the intensity of manual labor, making it suitable for widespread application.

All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
