Abstract
Description
Technical Field
[0001] This application relates to the field of railway engineering equipment technology, and in particular to a water system for railway engineering vehicles and a railway engineering vehicle. Background Technology
[0002] Railway engineering vehicles provide mobile living quarters for personnel engaged in railway line construction, inspection, and maintenance. With the continuous growth of my country's railway mileage, railway construction often involves remote sections with harsh working environments (such as water shortages and inconvenient supply lines), making the guarantee of drinking water for railway maintenance personnel a critical need.
[0003] Currently, the domestic water supply of railway engineering vehicles relies entirely on the water tanks on the vehicles. However, the water tank capacity is limited. When used in water-intensive vehicles such as shower cars and dining cars, it is necessary to frequently search for water sources to replenish the water. Especially in remote construction sites, replenishing water is difficult and inefficient, which increases the extra burden on the staff. Moreover, the water in the tank is "stagnant water" (without flow and circulation), which is prone to bacterial growth and deterioration, affecting the hygiene of the water supply. When the water tank is cleaned, the water supply on the vehicle is restricted.
[0004] It is evident that a water system is urgently needed to solve the technical problem that existing railway engineering vehicles rely entirely on onboard water tanks for water supply. Utility Model Content
[0005] This application provides a water supply system for railway engineering vehicles and a railway engineering vehicle to solve the technical problem that railway engineering vehicles rely entirely on onboard water tanks for water supply.
[0006] To address the aforementioned problems, this application provides a water supply system for railway engineering vehicles, comprising:
[0007] The water tank has an inlet and an outlet;
[0008] A water pipe is used, with one end connected to the water outlet and the other end used to connect to water facilities;
[0009] The water supply pipeline includes a first water supply end, a first water outlet end, and a second water outlet end. The first water supply end is used to connect to a water source, the first water outlet end is connected to the water inlet, and the second water outlet end is connected to the water supply pipeline for supplying water to water facilities.
[0010] The valve assembly includes a first valve, a second valve, and a third valve. The first valve is connected to the water supply pipeline and is located between the water outlet and the second water outlet. The second valve is connected to the second water outlet, and the third valve is connected to the first water outlet.
[0011] In some embodiments, the water supply pipeline further includes:
[0012] The second water inlet is used to connect to a water source, and the first water inlet and the second water inlet are used to be distributed at different azimuth angles of the railway engineering vehicle.
[0013] In some embodiments, the valve assembly further includes:
[0014] A fourth valve and a fifth valve, wherein the fourth valve is connected to the first water inlet and the fifth valve is connected to the second water inlet.
[0015] In some embodiments, the valve assembly further includes:
[0016] Sixth valve;
[0017] When the second connection end is connected to the first water inlet end, the sixth valve is connected to the first water inlet end and is located on the side of the fourth valve near the water tank, and the second connection end is located between the fourth valve and the sixth valve;
[0018] When the second connection end is connected to the second water inlet end, the sixth valve is connected to the second water inlet end and is located on the side of the fifth valve near the water tank, and the second connection end is located between the fifth valve and the sixth valve.
[0019] In some embodiments, the first valve, the second valve, and the third valve are linked in a coordinated control connection, the coordinated control connection including:
[0020] The first valve is opened, and the second and third valves are closed, so that the water tank can be directly supplied with water;
[0021] The second valve is opened, and the first and third valves are closed, so that the water source can supply water directly; and
[0022] The third valve is opened, and the first and second valves are closed, so that water is injected into the water tank.
[0023] In some embodiments, the water tank also has an overflow outlet connected to an overflow pipe.
[0024] This application also provides a railway engineering vehicle, including:
[0025] Engineering vehicle body,
[0026] Any of the railway engineering vehicle water systems described above.
[0027] In some embodiments, when the water supply pipeline includes a first water supply end and a second water supply end, the first water supply end and the second water supply end are located at different azimuth angles of the same end of the railway engineering vehicle.
[0028] In some embodiments, the first water inlet, the second water inlet, and the water tank are located at the same end.
[0029] The beneficial effects of the embodiments of this application are as follows: The railway engineering water supply system provided by this application, by setting a first water outlet and a second water outlet on the water supply pipeline, and connecting a third valve and a second valve to the first water outlet and the second water outlet respectively, allows the water system to both fill the water tank and supply water to the water facilities on the train, thereby reducing the dependence of the water supply system on the water tank. In this way, when the train arrives at a place with a water source, the water source under the train can be used directly to supply water to the water facilities on the train. On the one hand, this reduces the use of "stagnant water" in the water tank; on the other hand, the water facilities on the train can be used normally when the water tank is cleaned, improving the convenience and flexibility of the water supply system.
[0030] When the water supply pipeline includes a first water supply end and a second water supply end, and the first water supply end and the second water supply end are distributed at different azimuth angles of the railway engineering vehicle, they can be adapted to different water source locations, improving the flexibility and convenience of water supply system.

[0040] Please see Figure 1This application provides a water supply system for railway engineering vehicles, used on railway engineering vehicles to supply water to the water facilities on board. The water facilities on board may include, but are not limited to, handwashing basins, mop sinks, washing machines, toilets, and water dispensers.
[0041] The railway engineering vehicle water supply system provided in this application includes a water tank 10, a water supply pipeline 20, a water supply pipeline 30, and a valve assembly. The water tank 10 has an inlet 11 and an outlet 12. One end of the water supply pipeline 20 is connected to the outlet 12 of the water tank 10, and the other end is used to connect to water supply facilities. The water supply pipeline 30 includes a first water supply end 31, a first water outlet end 33, and a second water outlet end 34. The first water supply end 31 is used to connect to a water source, the first water outlet end 33 is connected to the inlet 11, and the second water outlet end 34 is connected to the water supply pipeline 20 to supply water to the water supply facilities. The valve assembly includes a first valve 41, a second valve 42, and a third valve 43. The first valve 41 is connected to the water supply pipeline 20 and located between the outlet 12 and the second water outlet end 34. The second valve 42 is connected to the second water outlet end 34, and the third valve 43 is connected to the first water outlet end 33.
[0042] By equipping the water supply pipe 30 with a first outlet 33 and a second outlet 34, and connecting a third valve 43 and a second valve 42 to the first outlet 33 and the second outlet 34 respectively, the water system can simultaneously fill the water tank 10 and supply water to the vehicle's water facilities, thereby reducing the water system's dependence on the water tank 10. In this way, when the vehicle reaches a water source, the water supply to the vehicle's water facilities can be directly utilized. This reduces the use of stagnant water in the water tank 10, and allows the vehicle's water facilities to function normally while the water tank 10 is being cleaned, improving the convenience and flexibility of the water system.
[0043] Water tank 10 is used for water storage. The inlet 11 of water tank 10 is used to fill water into water tank 10, and the outlet 12 of water tank 10 is used to supply water to water-using facilities through water pipe 20. It can be understood that water pipe 20 has one inlet port and multiple outlet ports. The inlet port of water pipe 20 is connected to the outlet 12 of water tank 10, and the multiple outlet ports of water pipe 20 are respectively connected to various water-using facilities on the vehicle. For example, water pipe 20 may include a main water pipe and multiple branch water pipes located at one end of the main water pipe. Figure 1As shown, the first valve 41 is connected to the main water pipe of the water supply pipeline 20 and is located near the outlet 12 of the water tank 10, so that the first valve 41 can control the opening and closing of the outlet 12. Of course, in some embodiments, the water tank 10 may also have an overflow outlet 13, which is connected to an overflow pipe 60. When water flows out of the overflow outlet 13, it can be determined that the water tank 10 is full, and water filling will stop. In addition, it should be noted that in order to ensure the normal water supply of the water tank 10, a booster pump 70 may also be connected to the water supply pipeline 20. For example, the booster pump 70 may be located between the first valve 41 and the outlet 12, but it is not limited to this.
[0044] The water supply pipe 30 includes a first water inlet 31, a first water outlet 33, and a second water outlet 34. It should be noted that the first water inlet 31, the first water outlet 33, and the second water outlet 34 in this embodiment can be understood as a section of the pipe near the port, including the port, but not limited to it. For example, as... Figure 1 As shown, the water supply pipeline 30 may also include a main water pipe and two branch water pipes located at one end of the main water pipe. The first water supply end 31 is located in the main water pipe, and the first water outlet end 33 and the second water outlet end 34 are located in the two branch water pipes respectively.
[0045] The first water inlet 31 of the water supply pipeline 30 is used to connect to a water source. For example, the water source can be urban water supply. When a railway engineering vehicle arrives at a location with a water source, the water source is connected to the port of the first water inlet 31 via a water supply pipe, thus connecting the water source to the water supply pipeline 30. The water can then enter the water tank 10 through the first outlet 33 of the water supply pipeline 30 and the inlet 11 to fill the water tank 10; alternatively, the water can enter the water supply pipeline 20 through the second outlet 34 of the water supply pipeline 30 to supply water to the water facilities. It can be understood that when the third valve 43 is open, the first valve 41 and the second valve 42 are closed, and the water supply pipeline 30 is used to fill the water tank 10; when the second valve 42 is open, the first valve 41 and the third valve 43 are closed, and the water supply pipeline 30 is used to supply water to the water facilities.
[0046] It should be noted that the second water outlet 34 is connected to the water supply pipe 20, which means that the port of the second water outlet 34 is connected to the main water pipe of the water supply pipe 20, and the connection point between the second water outlet 34 and the water supply pipe 20 is located on the side of the first valve 41 away from the water tank 10.
[0047] This application does not limit the specific types of the first valve 41, the second valve 42, and the third valve 43. For example, they can be ball valves (A-type), but are not limited thereto. In some embodiments, the first valve 41, the second valve 42, and the third valve 43 are linked in a control connection. This linkage control connection can include: the first valve 41 is open, and the second valve 42 and the third valve 43 are closed to allow the water tank 10 to be directly supplied with water, which can be defined as a "water tank 10 water supply mode"; the second valve 42 is open, and the first valve 41 and the third valve 43 are closed to allow the water source to be directly supplied with water, which can be defined as a "water source water supply mode"; the third valve 43 is open, and the first valve 41 and the second valve 42 are closed to allow the water source to inject water into the water tank 10, which can be defined as a "water source water injection mode".
[0048] In this embodiment, there are no restrictions on the specific linkage control method for the first valve 41, the second valve 42, and the third valve 43. Existing valve linkage control methods can be used. For example, linkage control can be performed through a PLC controller, which can be installed on a railway engineering vehicle.
[0049] This embodiment of the application connects and controls three valves—first valve 41, second valve 42, and third valve 43—in a coordinated manner, allowing users to switch between "water tank 10 water supply mode," "water source water supply mode," and "water source water injection mode," thereby improving the flexibility and convenience of using the water system.
[0050] like Figure 2 As shown, in some embodiments, the water supply pipe 30 may also include a second water supply end 32, which is also used to connect to a water source, and the first water supply end 31 and the second water supply end 32 are used to be distributed at different azimuth angles of the railway engineering vehicle.
[0051] By including a first water inlet 31 and a second water inlet 32 in the water supply pipeline 30, and distributing the first water inlet 31 and the second water inlet 32 at different azimuth angles of the railway engineering vehicle, the railway engineering vehicle can be adapted to different water source locations, thereby improving the flexibility and convenience of water supply in the water system.
[0052] It should be noted that when the above-mentioned pipeline includes a first water inlet 31 and a second water inlet 32, a branch water pipe can be connected to the end of the main water pipe of the water inlet pipeline 30 that is away from the first water outlet 33 and the second water outlet 34, so that the second water inlet 32 is located on the branch water pipe. However, it is not limited to this. When the second water inlet 32 is connected to the water source, the water can flow through the water inlet pipeline 30 to the first water outlet 33 and the second water outlet 34.
[0053] When the water supply pipe 30 includes a first water supply end 31 and a second water supply end 32, correspondingly, in some embodiments, the valve assembly may further include a fourth valve 44 and a fifth valve 45. The fourth valve 44 is connected to the first water supply end 31 to control the opening and closing of the corresponding port of the first water supply end 31; the fifth valve 45 is connected to the second water supply end 32 to control the opening and closing of the corresponding port of the second water supply end 32. For example, the fourth valve 44 and the fifth valve 45 can be positioned close to the ports of the first water supply end 31 and the second water supply end 32, respectively. When the first water supply end 31 is connected to a water source, the fifth valve 45 is closed; when the second water supply end 32 is connected to a water source, the fourth valve 44 is closed.
[0054] like Figure 2 As shown, in some embodiments, the water supply system for railway engineering vehicles also includes an undercarriage connecting pipe 50. The undercarriage connecting pipe 50 can be used for water transport between different railway engineering vehicles, improving the flexibility of water supply for railway engineering vehicles. For example, the undercarriage connecting pipe 50 may have a first connecting end and a second connecting end. The first connecting end is used to connect to the water supply system of other railway engineering vehicles, and the second connecting end is connected to one of the first water inlet end 31 and the second water inlet end 32. Thus, when two railway engineering vehicles are connected through the undercarriage connecting pipe 50, and when the first water inlet end 31 or the second water inlet end 32 of one railway engineering vehicle is connected to a water source, water can be supplied to the other railway engineering vehicle through the undercarriage connecting pipe 50.
[0055] When the water supply system for railway engineering vehicles includes an under-vehicle through pipe 50, correspondingly, in some embodiments, the valve assembly may also include a sixth valve 46. When the second connection end is connected to the first water inlet end 31, the sixth valve 46 is connected to the first water inlet end 31 and located on the side of the fourth valve 44 near the water tank 10, with the second connection end located between the fourth valve 44 and the sixth valve 46; when the second connection end is connected to the second water inlet end 32, the sixth valve 46 is connected to the second water inlet end 32 and located on the side of the fifth valve 45 near the water tank 10, with the second connection end located between the fifth valve 45 and the sixth valve 46.
[0056] like Figure 2As shown, this embodiment of the application takes the connection between the undercarriage through pipe 50 and the second water inlet 32 as an example. When the first water inlet 31 is connected to a water source, the fourth valve 44 is opened and the fifth valve 45 is closed. The water source can be divided into three paths after passing through the fourth valve 44. One path can supply water to the water-using facilities through the second valve 42, another path can fill the water tank 10 through the third valve 43, and the third path can enter the undercarriage through pipe 50 through the sixth valve 46, thereby supplying water to other railway engineering vehicles. Similarly, when the second water inlet 32 is connected to a water source, the fifth valve 45 is opened and the fourth valve 44 is closed. The water source can be divided into two paths after passing through the fifth valve 45. One path enters the undercarriage through pipe 50, and the other path is divided into two paths after passing through the sixth valve 46. One path can supply water to the water-using facilities through the second valve 42, and the other path can fill the water tank 10 through the third valve 43. It is understandable that a shut-off valve 47 can also be connected to the under-vehicle through pipe 50. When water is not needed to be supplied to the under-vehicle through pipe 50, the shut-off valve 47 can be closed.
[0057] In addition, it should be noted that a filter 80 can also be connected to the first water inlet 31 and the second water inlet 32. The filter 80 can be connected to one side of the water inlet of the fourth valve 44 and the fifth valve 45.
[0058] like Figure 3 As shown, in some embodiments, this application also provides a railway engineering vehicle, which includes the vehicle body and the water system of the railway engineering vehicle in any of the above embodiments.
[0059] In some embodiments, when the water supply system of a railway engineering vehicle includes a first water inlet 31 and a second water inlet 32, the first water inlet 31 and the second water inlet 32 can be located at different azimuth angles of the same end of the railway engineering vehicle. For example, the first water inlet 31 and the second water inlet 32 can be located at the third and fourth azimuth angles of the second end, respectively, so that the first water inlet 31 and the second water inlet 32 are respectively used to connect the water sources of the first and second ends of the railway engineering vehicle.
[0060] In some embodiments, the water tank 10 and the first water inlet 31 and the second water inlet 32 can be located at the same end of the railway engineering vehicle, thereby reducing the transportation distance during water injection.
[0061] The railway engineering vehicle provided in this application adopts all the technical solutions of the railway engineering vehicle water system in the above embodiments, and therefore has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.
[0062] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
