[0025] As Figures 1 to 4 The present application provides a rail passenger car integrated water supply system, which comprises a water supply end, an integrated water supply device, a main water supply pipeline 600 and a water use end. The water supply device is arranged integrally in the present application, which reduces the complexity of the overall structure of the water supply system, facilitates installation, and is convenient to operate, can effectively shorten the time of switching the water supply mode, thereby improving the water supply efficiency. Specifically: The water supply end is used to supply water to the rail passenger car.

[0026] The integrated water supply device is installed below the roof of the rail passenger car. The attendant room has a larger indoor space, so the integrated water supply device can be installed below the roof of the rail passenger car in the attendant room. The integrated water supply device comprises a plurality of integrated water supply pipelines. The integrated water supply device is connected with the water supply end through the integrated water supply pipelines. The integrated water supply device realizes a plurality of water supply modes and drainage modes by switching on and off the integrated water supply pipelines.

[0027] In the prior art, the valves for the water supply system are installed above the roof of the bus. Therefore, the pipes and pipe sections above the roof are scattered in various places and need to be installed and fixed separately. In this application, the integrated water supply device is installed below the roof, which integrates all the installation operations and pipe sections into one location, greatly reducing the difficulty of installation and operation.

[0028] The main water supply pipeline 600 is connected to the integrated water supply pipeline. The main water supply pipeline 600 is laid along the body of the rail vehicle to ensure that all water points inside the vehicle can be connected to the water supply pipeline.

[0029] like Figure 1 As shown, the water supply area includes at least a toilet room, a tea room, and a washroom, specifically: The toilet facilities are equipped with water supply pipes. The toilet facilities include a first toilet stall and a second toilet stall. The water supply pipes include a first toilet water supply pipe 701 and a second toilet water supply pipe 703. The first toilet stall is equipped with a toilet seat 702, which is connected to the main water supply pipe 600 via the first toilet water supply pipe 701. The toilet seat 702 can be flushed after use. The second toilet stall is equipped with a squat toilet 704, a second flushing faucet 705, a water-saving valve 706, and a washbasin. The water-saving valve 706, the second flushing faucet 705, and the squat toilet 704 are all connected to the main water supply pipe 600 via the second toilet water supply pipe 703. The washbasin is located below the water-saving valve 706 and can be flushed after use. Other items can also be washed in the second toilet stall via the second flushing faucet 705 and the water-saving valve 706.

[0030] The tea stove room is equipped with a water supply pipe 708 for tea stoves. An electric tea stove 709 is installed in the tea stove room. The electric tea stove 709 is connected to the main water supply pipe 600 through the water supply pipe 708 for tea stoves. The electric tea stove 709 can heat water for passengers or staff to use.

[0031] The washroom is equipped with a water supply line 710. The washroom includes two sets of hot and cold water-saving valves 711 and a first flushing faucet 712. A washbasin 707 is located below each of the hot and cold water-saving valves 711. The hot and cold water-saving valves 711 and the first flushing faucet 712 are connected to the main water supply line 600 via the water supply line 710. Passengers or staff can use the hot and cold water-saving valves 711 to control the water flow for washing in the washroom, and can also use the first flushing faucet 712 to rinse other items. Used water is drained to the outside of the vehicle through a drain pipe (not shown in the figure) and a drain valve 713 below the washbasin 707.

[0032] When installing, the staff first pre-assembles the various integrated water supply pipelines and the valves thereon to form a modular structure, and then installs the entire modular structure integrally under the roof of the vehicle by welding, screws or the like. Compared with the mode of dispersing the water supply pipelines and valves above the roof of the vehicle, the installation difficulty is greatly reduced, and the installation efficiency is improved; and since the valves are integrally arranged in the attendant room, the staff can be fixed at a certain place to operate, greatly improving the operation and water supply efficiency.

[0033] When in use, the staff adjusts the integrated water supply device according to the different water demand of the water end, controls the on-off of the valves on the integrated water supply pipeline, and realizes different water supply modes by the water supply end to meet the water demand.

[0034] The water supply end includes a water tank 800 and an external water source. The water tank 800 is arranged on the rail car. In the embodiment, the number of water tanks 800 is one. A through passage 900 is arranged below the rail vehicle. The external water source delivers water to the inside of the rail vehicle through the through passage 900. Multiple water injection ports can be arranged on the through passage 900. The water injection ports are connected with the water injection valves 902 and the external water source through the water injection pipelines 901. The external water source injects water into the through passage 900 through the multiple water injection ports and the water injection pipelines 901, which can improve the efficiency of the external water source supplying water to the rail car. When the vehicle is stationary, the external water source supplies water to the vehicle water supply system. The external water source can be a vehicle garage or a water tank truck.

[0035] By the double water supply mode of the water tank 800 and the external water source, the number of water tanks 800 arranged inside the vehicle can be reduced, the load weight of the vehicle body during operation can be reduced, and the transportation efficiency can be improved. When the rail vehicle is stationary, the external water source can supply water or replenish the water tank 800, so as to ensure sufficient water supply for the rail vehicle and avoid the phenomenon of no water supply.

[0036] The water tank 800 is arranged at a high position inside the rail car and is higher than the main water supply pipeline 600, the integrated water supply device and the water end. Such arrangement can provide a larger water pressure and ensure the water outlet of the water end.

[0037] As shown in Figure 1 , Figure 2 The integrated water supply pipeline includes: A first water supply pipeline 100, one end of the first water supply pipeline 100 is connected with the water tank 800, and a first valve 101 is arranged on the first water supply pipeline 100. The first water supply pipeline 100 functions to input the water in the water tank 800 into the integrated water supply device.

[0038] The second water supply pipeline 200 has one end connected with the end of the first water supply pipeline 100 away from the water tank 800, and the other end connected with the main water supply pipeline 600, and is provided with a second valve 201.

[0039] The third water supply pipeline 300 has one end connected with an external water source, and the other end connected with the second water supply pipeline 200, and is provided with a third valve 301. The third water supply pipeline 300 is used to input water in the external water source into the integrated water supply device.

[0040] The fourth water supply pipeline 400 has one end connected with the third water supply pipeline 300, and the other end connected with the water tank 800, and is provided with a fourth valve 401. The fourth water supply pipeline 400 is used to input water in the external water source into the water tank 800 to supply water to the water tank 800.

[0041] The first water supply pipeline 100, the second water supply pipeline 200, the third water supply pipeline 300 and the fourth water supply pipeline 400 are arranged in parallel, which facilitates the assembly of the integrated water supply device and reduces the installation space required by the integrated water supply device.

[0042] In addition, the pipeline interface of the first water supply pipeline 100 connected with the water tank 800 is arranged close to the bottom surface of the water tank 800, so that all the water in the water tank 800 can be input into the integrated water supply device; the pipe opening of the fourth water supply pipeline 400 located inside the water tank 800 is arranged close to the top surface of the water tank 800, so that the problem of poor water supply from the external water source to the water tank 800 under the action of water pressure can be avoided, thereby improving the efficiency of water supply from the external water source to the water tank 800.

[0043] The integrated water supply pipeline further comprises a fifth water supply pipeline 500, which is respectively communicated with the first water supply pipeline 100, the second water supply pipeline 200, the third water supply pipeline 300 and the fourth water supply pipeline 400, and is provided with a fifth valve 501 at one end communicated with the first water supply pipeline 100, the second water supply pipeline 200, the third water supply pipeline 300 and the fourth water supply pipeline 400. The fifth water supply pipeline 500 is used to drain the water in the integrated water supply device.

[0044] The overflow device is arranged on the water tank 800 and is used for preventing water in the water tank 800 from overflowing. The overflow device can be an overflow pipeline 801. One end of the overflow pipeline 801 is connected with the water tank 800, and the other end of the overflow pipeline 801 can be connected with a drain pipeline or directly located outside the vehicle. The opening of the overflow pipeline 801 located inside the water tank 800 is arranged close to the top surface of the water tank 800. In this way, when the water level in the water tank 800 reaches the opening of the overflow pipeline 801, the water can be drained in time, thereby preventing the water in the water tank 800 from overflowing.

[0045] As shown in FIG. 1, according to the on-off of the first water supply pipeline 100, the second water supply pipeline 200, the third water supply pipeline 300, the fourth water supply pipeline 400 and the fifth water supply pipeline 500, different water supply modes can be realized. The water supply modes include: Figure 3 a water tank water supply mode, in which the first valve 101 and the second valve 201 are opened, and the third valve 301, the fourth valve 401 and the fifth valve 501 are closed. At this time, the first water supply pipeline 100, the second water supply pipeline 200 and the main water supply pipeline 600 form a passage. The water in the water tank 800 enters the main water supply pipeline 600 in sequence via the first water supply pipeline 100 and the second water supply pipeline 200, and is supplied to the water end. The water end can be used by opening the valve corresponding to the water end.

[0046] an external water source water supply mode, in which the second valve 201 and the third valve 301 are opened, and the first valve 101, the fourth valve 401 and the fifth valve 501 are closed. At this time, the third water supply pipeline 300, the second water supply pipeline 200 and the main water supply pipeline 600 form a passage. The water of the external water source enters the main water supply pipeline 600 in sequence via the third water supply pipeline 300 and the second water supply pipeline 200, and is supplied to the water end. The water end can be used by opening the valve corresponding to the water end.

[0047] an external water source water supply mode, in which the second valve 201 and the third valve 301 are opened, and the first valve 101, the fourth valve 401 and the fifth valve 501 are closed. At this time, the third water supply pipeline 300, the second water supply pipeline 200 and the main water supply pipeline 600 form a passage. The water of the external water source enters the main water supply pipeline 600 in sequence via the third water supply pipeline 300 and the second water supply pipeline 200, and is supplied to the water end. The water end can be used by opening the valve corresponding to the water end.

[0048] ​When in a lower temperature environment (usually from October to May each year), in order to avoid the case that the water stored in the pipeline is frozen to cause the pipeline to be damaged when the vehicle is not running, the water in the vehicle pipeline needs to be completely emptied through the drainage mode. The drainage mode is: opening the first valve 101, the second valve 201, the third valve 301, the fourth valve 401 and the fifth valve 501. At this time, the main water supply pipeline 600, the first water supply pipeline 100, the second water supply pipeline 200, the third water supply pipeline 300, the fourth water supply pipeline 400 and the fifth water supply pipeline 500 are all passageways, which can drain the accumulated water in the first water supply pipeline 100, the second water supply pipeline 200, the third water supply pipeline 300, the fourth water supply pipeline 400 and the main water supply pipeline 600 under the action of gravity; In addition, all the valves at the water use end, such as the cold and hot water saving valve 711 in the washroom, the flushing faucet, the drain valve 713, and the water saving valve 706 and the flushing faucet in the toilet, are also opened for drainage to improve the anti-freezing effect.

[0049] The track train floor below the fifth valve 501 is provided with a water leakage tray (not shown in the figure), and the water discharged from the main water supply pipeline 600, the first water supply pipeline 100, the second water supply pipeline 200, the third water supply pipeline 300, the fourth water supply pipeline 400 and the fifth water supply pipeline 500 will enter the drainage pipeline through the water leakage tray for discharge.

[0050] When the first valve 101, the second valve 201, the third valve 301, the fourth valve 401 and the fourth valve 401 are manual valves, when the water supply mode or the drainage mode needs to be adjusted, the staff can manually open or close the corresponding valve.

[0051] The track train integrated water supply system further comprises: An operation panel is arranged in the track train, and an operation button is arranged on the operation panel. The operation panel can set the water supply mode and the drainage mode. The schematic diagram of the operation panel is shown in Figure 4 .

[0052] A controller is connected with the first valve 101, the second valve 201, the third valve 301, the fourth valve 401, the fifth valve 501 and the operation panel. At this time, the first valve 101, the second valve 201, the third valve 301, the fourth valve 401 and the fifth valve 501 are all electric valves. The use of the operation panel controller and the electric valve greatly improves the automation degree of adjusting the water supply mode or the drainage mode, and the operation efficiency is higher than that of the manual operation mode. The improvement of the software method is not involved in the present application, so the control of the controller and the operation panel will not be described here.

[0053] The present application also provides a track train, which is provided with the track train integrated water supply system as described above.
