Description

Technical Field

[0001] This application belongs to the field of waste bin technology, and in particular relates to the waste bin body of the Hulk 200 km / h train. Background Technology

[0002] The "Green Giant" EMU (Electric Multiple Unit) has a design speed of 160 km / h, the same as the maximum speed of Z-series conventional passenger trains. The Green Giant's primary purpose is to improve the operational efficiency of existing passenger train lines, especially the passage capacity of large passenger stations, and to enhance passenger comfort. It is considered an upgrade to the 25T-type passenger train, designed to upgrade conventional lines, rather than as a supplement to high-speed distributed-power EMUs such as the Harmony and Fuxing trains.

[0003] Existing automatic sewage discharge devices include, for example, Chinese Patent Application No. 202022532504.1, and references... Figure 6 This invention discloses an automatic sewage discharge device for rail engineering vehicles, belonging to the field of automatic sewage discharge technology. The device integrates a sewage tank, a grey water tank, and a sewage pump station. The pump station contains a sewage pump, a sewage tank valve, and a grey water tank valve. When the integrated sewage tank is full and needs to be emptied, the vehicle travels to the discharge location. In stations without corresponding suction equipment, the sewage in the tank can be automatically discharged to the designated location through the control of the valve groups in the pump station. This provides the integrated sewage tank with an automatic sewage discharge system, eliminating the need for external sewage discharge equipment, reducing discharge conditions, and improving discharge efficiency.

[0004] While the aforementioned automatic sewage discharge device can achieve automatic sewage discharge, the sewage pumps in the pump house occupy a large space, and the numerous and complex pipe and valve assemblies connected to the pumps not only make the entire pump house occupy a significant amount of space in the sewage tank, but also complicate the sewage discharge process, which requires the use of the sewage pumps. Therefore, this paper proposes a sewage tank design for the Green Giant 200km / h train, which features a simpler sewage discharge structure and a smaller pump house footprint. Utility Model Content

[0019] To make the objectives, technical solutions, design methods, and advantages of this application clearer, the following detailed description, in conjunction with the accompanying drawings, provides specific embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application.

[0020] This application relates to a waste bin body for the Green Giant 200km / h train, and its specific implementation method is as follows: Please refer to... Figures 1-5 As shown, the waste bin body includes an integrated waste bin 1, which integrates a waste bin (not shown) for storing waste and a grey water bin 2 for storing grey water; the integrated waste bin 1 is provided with a waste inlet 3, which is connected to the waste bin through a pipe; The grey water tank 2 is located inside one end of the integrated waste tank 1. A first waste inlet pipe 4 is connected to the grey water tank 2. One end of the first waste inlet pipe 4 is connected to the waste tank, and the other end is connected to the grey water tank 2. A clamp valve 5 is connected to the first waste inlet pipe 4. A solenoid valve 6 and a pressure reducing valve 7 are provided on the grey water tank 2. The solenoid valve 6 is connected to the clamp valve 5 and the pressure reducing valve 7 respectively through an air pipe. The other end of the pressure reducing valve 7 is connected to an external air source. An inspection door 8 is provided on the grey water tank 2 above the solenoid valve 6. A junction box 9 is provided on the waist of the integrated waste tank 1 on the same side as the grey water tank 2. The junction box 9 is electrically connected to the solenoid valve 6. An inspection unit 10 is provided between the solenoid valve 6 and the junction box 9.

[0021] In the above embodiment, the grey water from the tractor's handwashing station is collected by gravity and temporarily stored in a grey water tank located in an integrated waste bin under the vehicle.

One end of the vacuum tube 30 is located in the integrated waste tank, and the other end is connected to an external air source (air extraction). When train waste needs to be discharged into the integrated waste bin, an external air source evacuates the integrated waste bin through a vacuum tube to maintain a sufficient vacuum inside the bin, creating negative pressure with the train's waste outlet, so that the waste generated by the train can be effectively sucked into the integrated waste bin. If the integrated waste bin needs to be discharged, two air inlet valves are used to remove the vacuum effect in the integrated waste bin, making it easier to discharge waste.

[0025] In the above, the integrated waste tank 1 includes a support frame 31, and the waste tank and the grey water tank 2 are enclosed in the support frame 31.

[0027] In the above implementation, the waste tank has four liquid levels: 25%, 50%, 75%, and 100%. When the liquid level reaches 25%, an alarm signal is issued and heating of the tank is prohibited. When the liquid level reaches 75%, an alarm signal is issued. When the liquid level in the waste tank reaches 100%, the tank is prohibited from use.

At the same time, start the sewage pump to discharge the sludge from the sludge tank. In the above-mentioned emptying process, the sewage in the temporary storage box is sucked into the sewage box by the clamp valve, solenoid valve and pressure reducing valve, and the sewage drain valve directly empties the water in the temporary storage box; the sewage discharge process is simplified, and sewage discharge can be easily achieved by the cooperation of solenoid valve, clamp valve and pressure reducing valve. Moreover, the entire sewage discharge structure occupies little space, which achieves the effect of reducing the weight of the train.
