[0024] like Figure 1-Figure 2As shown, in this embodiment: a discharge pipe 4 is inserted at the bottom end of the waste box body 1, the discharge pipe 4 is located at the bottom end of the spherical bottom surface 12, and is used to discharge materials; the effect achieved by the above components is: when the train arrives at the station and the waste in the waste storage chamber 11 needs to be discharged, the waste will be discharged through the discharge pipe 4. Since the discharge pipe 4 is located at the bottom end of the spherical bottom surface 12, the waste will not accumulate too much and will only adhere to the side wall of the waste storage chamber 11 and the spherical bottom surface 12.

[0025] like Figure 1-Figure 2 As shown, in this embodiment: a solenoid valve 7 is provided on the discharge pipe 4, and the solenoid valve 7 is used to control the opening and closing of the discharge pipe 4; the effect achieved by the above components is: the solenoid valve 7 can control the opening and closing of the discharge pipe 4. When the train arrives at the station and needs to discharge dirt, the solenoid valve 7 opens to discharge the dirt. When the train is running, the solenoid valve 7 is closed to store the dirt in the dirt storage chamber 11.

[0026] like Figure 1-Figure 2 As shown, in this embodiment: a cleaning mechanism 5 is provided in the dirt box body 1, and the cleaning mechanism 5 is used to clean the spherical bottom surface 12. The cleaning mechanism 5 includes a motor 51 fixedly mounted on the top of the dirt box body 1, and the output end of the motor 51 is fixedly connected to a rotating shaft 52. The rotating shaft 52 extends into the dirt storage chamber 11, and a sleeve 53 is fixedly sleeved on the free end. The sleeve 53 is located at the opening of the discharge pipe 4, and a plurality of steel brushes 54 are evenly fixedly mounted on the outer wall of the sleeve 53. The plurality of steel brushes 54 are slidably connected to the upper surface of the spherical bottom surface 12; the effect achieved by the above components is that the dirt slides along the spherical bottom surface 12 under the action of gravity and is discharged through the discharge pipe 4 , but there will still be dirt adhering to the spherical bottom surface 12. At this time, the cleaning mechanism 5 can clean up the dirt adhering to the spherical bottom surface 12; the output end of the motor 51 drives the rotating shaft 52 to rotate, and the rotating shaft 52 drives several steel brushes 54 to rotate synchronously through the sleeve 53. Since the steel brushes 54 are attached to the upper surface of the spherical bottom surface 12, the dirt adhering to the upper surface of the spherical bottom surface 12 can be scraped off; since the sleeve 53 is located at the opening of the discharge pipe 4, the several steel brushes 54 evenly fixed on the outer wall of the sleeve 53 can adhere to the upper surface of the spherical bottom surface 12, which is convenient for subsequent cleaning of the dirt adhering to the upper surface of the spherical bottom surface 12.

[0027] like Figure 1-Figure 2As shown, in this embodiment: a water tank 2 is provided on the outer wall of the sewage tank body 1, and a spraying mechanism 6 is provided in the sewage tank body 1. The spraying mechanism 6 is used to flush the sewage storage cavity 11 and the spherical bottom surface 12. The spraying mechanism 6 includes a water inlet pipe 61 connected to the water tank 2 at one end, and the water inlet pipe 61 is inserted into the mounting block 62. The mounting block 62 is fixedly mounted on the upper surface of the sewage tank body 1. A water pump 63 is provided on the mounting block 62, and the water inlet pipe 61 is connected to the water pump 63; the effect achieved by the above components is that after the sewage is discharged under the action of gravity, some sewage will adhere to the side wall of the sewage storage cavity 11. At this time, the spraying mechanism 6 can flush down the sewage adhered to the side wall of the sewage storage cavity 11, and in the process of flow, it drives the sewage on the spherical bottom surface 12 scraped off by the cleaning mechanism 5 to be discharged through the discharge pipe 4; after the water pump 63 is working, it will draw clean water in the water tank 2 through the water inlet pipe 61.

[0028] like Figure 1-Figure 2 As shown, in this embodiment: the water pump 63 is also connected to a water outlet pipe 64, the free end of the water outlet pipe 64 passes through the upper end of the sewage tank body 1 and extends into the sewage storage chamber 11, and the free end of the water outlet pipe 64 is connected to a spray head 65, which is fixedly mounted on the inner wall of the top of the sewage tank body 1 and can rotate to spray; the effect achieved by the above components is: after the water pump 63 absorbs the clean water in the water tank 2, it is introduced into the spray head 65 through the water outlet pipe 64. Due to the use of the water pump 63 for absorption, the water sprayed from the spray head 65 will be a high-pressure water flow, which hits the side wall of the sewage storage chamber 11 and washes down the dirt adhering to the side wall of the sewage storage chamber 11. The downward flow of sewage will drive the dirt on the spherical bottom surface 12 scraped off by the cleaning mechanism 5 and be discharged through the discharge pipe 4; during the spraying process, the spray head 65 can rotate to flush the side wall of the sewage storage chamber 11 360 degrees without dead angles, and clean the side wall of the sewage storage chamber 11.

[0029] The operating principle of the present invention is as follows: when the train arrives at the station and the dirt in the dirt storage chamber 11 needs to be discharged, first, the solenoid valve 7 is opened, and the dirt in the dirt storage chamber 11 is discharged through the discharge pipe 4 under the action of gravity. Then, the motor 51 is started, and the output end of the motor 51 drives the rotating shaft 52 to rotate. The rotating shaft 52 drives a number of steel brushes 54 to rotate synchronously through the sleeve 53. The steel brushes 54 scrape off the dirt adhering to the upper surface of the spherical bottom surface 12. At the same time, the water pump 63 is started, and the water pump 63 draws clean water in the water tank 2 through the water inlet pipe 61, and then guides the clean water to the spray head 65 through the water outlet pipe 64. The spray head 65 sprays a high-pressure water flow to the side wall of the dirt storage chamber 11, flushing down the dirt adhering to the side wall of the dirt storage chamber 11. The sewage flows downward and drives the dirt on the spherical bottom surface 12 scraped off by the cleaning mechanism 5 to be discharged through the discharge pipe 4. After cleaning, the motor 51 and the water pump 63 are turned off, and finally the solenoid valve 7 is closed.
