The connecting pipe 14 is provided with a solenoid valve for controlling the opening or closing of the connecting pipe 14. The water tank 1 is connected with a drain pipe and the drain pipe is also provided with a solenoid valve. When the weather is cold and the train is not running, the solenoid valve on the drain pipe can be opened to drain the water in the water tank 1 to prevent the water in the water tank 1 from freezing in the water tank 1.

In the embodiment of the present application, the first heating pack 31 is made of calcined diatomaceous earth, iron powder, aluminum powder, coke powder, activated carbon, salt, quicklime, sodium carbonate and other materials. After the tensioning part 5 loosens the supporting plate 41, the supporting plate 41 will flip downward. At this time, the first heating pack 31 on the supporting plate 41 will fall to the bottom of the tank body 15 and combine with the pure water in the tank body 15. Due to the presence of quicklime, a large amount of heat will be generated, thereby heating the water storage tank 1 to prevent the water in the water storage tank 1 from freezing quickly.

The tightening part 7 is arranged on the sleeve 2, the puncturing part 8 is connected between the tightening part 7 and the sleeve 2, and the sealing part 9 is arranged on the puncturing part 8. After the battery fails to supply power, the tightening part 7 will release the puncturing part 8, and the puncturing part 8 will puncture the second heating part 6, so that the second heating part 6 will heat the connecting tube 14 to prevent the water in the connecting tube 14 from freezing and causing the connecting tube 14 to burst. In the embodiment of the present application, only the vertical section of the connecting tube 14 is used as an illustration; after the puncturing part 8 punctures the second heating part 6, the sealing part 9 will be sealed to prevent the water between the sleeve 2 and the connecting tube 14 from flowing to the tightening part 7 and damaging the tightening part 7.

[0045] Reference Figure 4 The second heating part 6 includes a second heating pack 62 and a water bag 61. The water bag 61 can be made of rubber material.

After the battery fails to supply power, the tightening part 7 will release the puncturing part 8, and the puncturing part 8 will puncture the water bag 61. The water in the water bag 61 will gush out and combine with the second heating pack 62, thereby generating a large amount of heat to heat the connecting pipe 14, thereby preventing the water in the connecting pipe 14 from freezing and causing the connecting pipe 14 to burst.

[0046] Reference Figure 4 The tightening part 7 includes a second electromagnetic suction cup 71 and a second iron plate 72. A cavity 21 is provided inside the side wall of the sleeve 2. The second electromagnetic suction cup 71 is fixed to the side of the cavity 21 away from the connecting pipe 14. The second iron plate 72 is slidably connected to the inner wall of the cavity 21 and slides in the horizontal direction. The second iron plate 72 and the second electromagnetic suction cup 71 attract each other. The piercing part 8 is arranged between the second iron plate 72 and the inner wall of the cavity 21 close to the connecting pipe 14. After the battery fails to supply power, the second electromagnetic suction cup 71 will no longer attract the second iron plate 72. At this time, the second iron plate 72 will slide to one side of the connecting pipe 14, thereby driving the piercing part 8 to pierce the water bag 61.

[0047] Reference Figure 4The puncture part 8 includes a needle 81 and a spring 82. The needle 81 is fixed to the side of the second iron plate 72 away from the second electromagnetic suction cup 71 and is located in the cavity 21. The inner wall of the sleeve 2 is provided with a clearance hole 22 for the needle 81 to penetrate, and the clearance hole 22 is connected to the cavity 21. One end of the spring 82 is fixed to the side of the second iron plate 72 away from the second electromagnetic suction cup 71, and the other end is fixed to the side of the cavity 21 close to the connecting pipe 14, and the needle 81 is penetrated by the spring 82. The sealing part 9 is fixed on the needle 81. After the battery fails to supply power, the second electromagnetic suction cup 71 will no longer attract the second iron plate 72. At this time, the second iron plate 72 will drive the needle 81 to slide toward the side of the connecting pipe 14 through the retraction of the spring 82, so that the needle 81 will penetrate the clearance hole 22 and puncture the water bag 61 in the sleeve 2.

[0048] Reference Figure 4 The sealing part 9 includes a sealing plate 91 and a sealing strip 92. The sealing plate 91 is fixedly sleeved on the puncture needle 81, and the sealing strip 92 is fixed to the side of the sealing plate 91 away from the second iron plate 72. The inner wall of the cavity 21 near the connecting pipe 14 is provided with a sealing groove 211 for the sealing strip 92 to be inserted. After the puncture needle 81 punctures the water bag 61, the sealing strip 92 is inserted into the sealing groove 211 by interference, thereby improving the sealing of the cavity 21 to prevent the water in the sleeve 2 from flowing into the cavity 21 and damaging the second electromagnetic chuck 71.

[0049] In addition, the outer side walls of the sleeve 2 and the tank body 15 are fixedly provided with a heat preservation plate 10, which can prevent the heat from disappearing quickly, thereby extending the heat retention time.

[0050] Reference Figure 2 The bottom of the sleeve 2 and the tank body 15 are both connected to each other and are provided with a water outlet pipe, and a manual valve is provided on the water outlet pipe. The bottom of the sleeve 2 and the tank body 15 are both provided with a switch door, and the switch door is sealed when closed. Once the first heating pack 31 and the second heating pack 62 in the tank body 15 and the sleeve 2 are used, the water in the sleeve 2 and the tank body 15 can be drained first, and then the switch door can be opened to take out the first heating pack 31 and the second heating pack 62.

[0051] The implementation principle of the antifreeze emptying system for the toilet of a high-speed train in the embodiment of the present application is as follows: after the battery fails to supply power, the first electromagnetic suction cup 51 will no longer attract the first iron plate 52; at this time, the first iron plate 52 will slide downward in the vertical direction, so that the supporting plate 41 will flip downward, so that the first heating pack 31 on the supporting plate 41 can fall to the inner bottom of the tank body 15; and combined with the pure water in the tank body 15, a large amount of heat will be generated due to the presence of quicklime, thereby heating the water storage tank 1 to prevent the water in the water storage tank 1 from freezing quickly;

[0052] After the battery fails to supply power, the second electromagnetic suction cup 71 will no longer attract the second iron plate 72. At this time, the second iron plate 72 will be pulled back by the spring 82, and the second iron plate 72 will drive the needle 81 to slide toward one side of the connecting tube 14, so that the needle 81 will penetrate the clearance hole 22 and puncture the water bag 61 in the sleeve 2; the water in the water bag 61 will gush out and combine with the second heating pack 62, thereby generating a large amount of heat to heat the connecting tube 14, thereby preventing the water in the connecting tube 14 from freezing and causing the connecting tube 14 to burst.
