Description

The invention relates to a section of a train containing connected wagons and plumbing devices located in a wagon of a train, in particular a high-speed train.

As a rule, a train is a train of several interconnected railway vehicles for rail transportation. Depending on the type of propulsion, different types of train sections are distinguished. In particular, the train can be set in motion using a single locomotive located at the beginning of the train. If such a locomotive is located at the end of the train, then we are talking about a pushed train. Moreover, railway vehicles attached to the locomotive in front or behind are called wagons. If several railway vehicles are connected in one, as a rule, inextricable section, and a motor is built into this section, then we are talking about the train section in the form of a motor-car rolling stock.

In more modern drive solutions, in particular in the field of high-speed rail transport, these rigid units are partially disassembled and used in separate drive solutions (for example, a motor car), in which each individual car can have its own drive units integrated into each car. In particular, each individual wheelset of a car can be equipped with its own drive unit. Moreover, such drive units are preferably implemented as electromechanical transformers.

In rail vehicles for passenger transportation, in particular, in high-speed trains, in addition to seats and seats, in most cases, there are also many sanitary devices, abbreviated as toilets or sanitary facilities. Their location and number inside the train section is focused on the maximum number of passengers carried and their distribution among individual sectors of the train or wagon. Since high-speed rail vehicles, as a rule, consist of several wagons (7-16), in the prior art, sanitary devices are respectively distributed over several wagons of the vehicle.

At the same time, in the section of the train containing connected wagons and sanitary devices located in the wagon, along with bathrooms with a toilet, full-fledged installations with fresh water are also installed, i.e. a filling device together with pipes leading to a fresh water tank, a fresh water tank, pipes laid in a carriage to a sanitary unit, and also a sewer system, i.e. sewer pipe, sewer tank and suction unit.

A section of a train is known from JP 2000229567 A (publ. 22/08/2000), which includes connected wagons and sanitary devices located in the car, with a plurality of sanitary devices giving one fresh water installation and one sewer system.

A disadvantage of the known technical solution is the distribution of the load, while the sanitary devices are distributed evenly across all the cars. This leads to the fact that the weight of a separate sanitary device is taken into account in the total weight of all the respective cars. Depending on the solution used in individual wagons, this can lead to a problem of maximum axle load. In particular, the additional integration of individual drive units due to their relatively large dead weight can be significantly limited by the maximum allowable load on the axis of the car. In addition, as a result, it becomes more difficult to manipulate the available space to accommodate other sections of the car.

The objective of the utility model is to create such a section of the train that would solve or at least reduce the described problems of the prior art when placing sanitary devices in trains. In particular, such a section of the train should provide the most uniform distribution of the axle load in the entire rail vehicle.

This problem is solved using the features of claim 1 of the utility model formula. In accordance with the utility model, a train section is proposed, which includes connected wagons and sanitary devices located in the car, with a plurality of sanitary devices giving one fresh water installation and one sewer system. The train section is characterized by the fact that only individual wagons of the indicated section of the train are equipped with sanitary devices, and the sanitary devices are located at one external end of the car, each of the sanitary devices located at one end of the car is connected using a common fresh water installation , and all sanitary devices of one car are connected using a common sewer system, with a common sewer system located in the middle of the car between the respective existing sanitary facilities.

The train section in accordance with the utility model has the advantage that due to the location of the common sewage system in the middle of the car between the corresponding sanitary-technical devices, the most uniform distribution of axle load in the entire rail vehicle is achieved.

The utility model is based on the idea that with the help of a modified section of the train with respect to the prior art in terms of the location of sanitary devices inside the train, it is possible to ensure optimal load distribution on the axis of the entire rail vehicle. In particular, using the train section in accordance with the utility model, it becomes possible to integrate additional drive elements that cannot be used in the prior art due to their large dead weight.

Due to the fact that sanitary devices are now not distributed to all cars, but only to some cars, the weight balance for critical cars is improved. In addition, the total number of sanitary devices remains the same, and the ratio between the maximum number of passengers and the number of sanitary devices also remains unchanged. In addition, due to the changed distribution of space, greater freedom is achieved in the planning and application of various spatial solutions inside an individual carriage of this composition.

In a preferred embodiment of the utility model, it is provided that the sanitary devices are preferably located only in every second carriage, starting from the first or second carriage.

Each of the sanitary devices located at one end of the car is interconnected using a common fresh water installation and a common sewer system.

It is preferable that all sanitary devices of one car are interconnected using a common fresh water installation and a common sewer system.

It is advisable that the general installation of fresh water and the general sewer system are located in the middle of the car between the corresponding sanitary-engineering devices.

The sewer system may include itself in order to ensure technical simplicity and reduce the weight of the sewage tank with a centralized vacuum system (instead of a sewage tank ventilated at atmospheric pressure or a system with ejectors installed in front of the sewer tank, each of which is responsible for pumping out on one of the sanitary devices ) This has the advantage that separate toilets no longer require fully equipped toilets.

The resulting total weight of all sanitary devices, as well as all fresh water installations and sewage systems of one car, is evenly distributed over the load on the individual wheel axles of the respective car.

Due to the displacement of the sanitary devices, free space is formed, which can be used for drive units (engine, transmission mechanisms, refrigerators, etc.).

In accordance with another embodiment of the utility model, the train section includes at least three cars connected to a common section, and at least two cars are equipped with their own drive devices (distributed traction) integrated in the respective car. As a modification, each section car includes its own, integrated drive devices. As an alternative, section wagons having sanitary fittings do not have drive units. Driving devices may include only those section cars that do not have sanitary facilities. Conversely, small and / or lightweight drive units can be integrated into wagons with sanitary fittings. One embodiment of the utility model provides that section wagons having sanitary fittings are free of volumetric and / or heavy drive devices, such as frequency converters or transformers.

The above properties, features and advantages of this utility model are explained in detail using the drawings. The drawings show the following:

figure 1 - section of the train in accordance with the prior art;

figure 2 - another section of the train in accordance with the prior art;

figure 3 is a section of a preferred embodiment of a utility model;

4 is a second variant of a train section in accordance with a utility model;

5 is another section of the train in accordance with the utility model.

Figure 1 shows a section 10 of a train with 7 cars 12.1-12.7 in accordance with the prior art, in which both external cars 12.1, 12.7 for aerodynamic reasons differ in shape from the internal cars 12.2-12.6. In this variant, the train section does not have fundamental functional differences between the individual cars 12.1–12.7, so they can be largely designed identically. In particular, in all cars there are sanitary devices 20.1–20.7 located in pairs at one end of the car, connected to each other by a common installation of fresh water 18.1–18.7 and a common sewage system 16.1–16.7. In this version of the train section, the sanitary devices 20.1–20.7 are evenly distributed throughout the rail vehicle. Due to the alignment on one side of the sanitary devices 20.1–20.7 in individual cars 12.1–12.7, the axle load resulting from this largely affects only the corresponding end of the car, therefore, without taking into account additional elements of the car, there is a strongly pronounced uneven load of the existing wheel axles. In such a section of a train with 14 toilets, with a maximum number of passengers of 500 people, a distribution coefficient of 35.71 passengers per toilet is obtained.

Figure 2 shows other sections of the train 10.1-10.3 for 7 cars 12.1-12.7 in each in accordance with the prior art, in which, in comparison with the train section of figure 1 in separate cars, they refused pairwise placement of sanitary devices. Thus, in the first section 10.1 of the train in the middle inner carriage 12.4, only one sanitary device 20.4 is provided, and in the second section 10.2 of the train in two outer cars 12.1, 12.7, one sanitary device 20.1, 20.7 is provided, respectively. In the third section 10.3 of the train, both of these alternatives are combined, therefore, in this case, both the two outer cars 12.1, 12.7 and the middle inner car 12.4 have only one sanitary device 20.1, 20.4, 20.7. Otherwise, the design of the sanitary devices substantially corresponds to the embodiment shown in FIG. 1, and thus the above explanations apply. Due to the reduced total number of sanitary devices compared to the train section of Fig. 1, a modified distribution coefficient is obtained, amounting to 38.46 passengers per toilet for the first section 10.1 of the train with 13 toilets, amounting to 41.67 passengers per toilet for the second section 10.2 of the train with 12 toilets, accounting for 45.45 passengers per toilet for the third section of the 10.3 train with 12 toilets.

Figure 3 shows one of the preferred embodiments of the utility model of the train section 10, in which only individual section cars have sanitary devices. In particular, a section of a train with 7 cars 12.1–12.7 is shown, in which sanitary devices 20.2, 20.4, 20.6 are located only in every second car, starting from the second car 12.2. In this case, the sanitary devices 20.2, 20.4, 20.6 are located individually or in pairs at the outer end of the interior of the car 12.2, 12.4, 12.6. The sanitary facilities located at the ends of the wagons are connected using a common fresh water installation 18.2, 18.4, 18.6, and all the sanitary facilities of one such wagon 12.2, 12.4, 12.6 are connected using a common sewage system 16.2, 16.4, 16.6. In this case, the sanitary devices 20.2, 20.4, 20.6 are placed in the respective inner cars 12.2, 12.4, 12.6 in such a way that the axle load generated by them is distributed evenly over the said inner cars 12.2, 12.4, 12.6. In general, in the train section according to the utility model according to this embodiment, 11 toilets are provided in the rail vehicle. Therefore, as shown in FIG. 2, the distribution coefficient is 45.45 people per toilet.

Figure 4 shows a second embodiment of a utility model of a section 10 of a train with 7 cars 12.1-12.7, in which the sanitary devices 20.2, 20.4, 20.6 located at one end of the car are connected to each other by means of a common installation 18.2, 18.4, 18.6 fresh water, and all sanitary devices of one car are connected to each other by means of a common sewer system 16.2, 16.4, 16.6. Otherwise, the design of the sanitary devices substantially corresponds to the embodiment shown in FIG. 3, and thus the above explanations apply. Also, the number of toilets and the final distribution coefficient do not change. However, the combination of appropriate sewer systems 18.2, 18.4, 18.6 leads to a significant reduction in weight compared to the prior art.

Figure 5 shows the third embodiment of the utility model, namely, section 10 of the train with 7 cars 12.1-12.7, and in contrast to the embodiment of figure 4, all sanitary devices of one car 12.1-12.7 are interconnected using a common installation 18.2 , 18.4, 18.6 fresh water and the general sewer system 16.2, 16.4, 16.6. Otherwise, the design of the sanitary facilities substantially corresponds to the embodiments shown in FIG. 3 and 4, and thus the above explanations apply. Also, the number of toilets and the final distribution coefficient do not change. However, the combination of the corresponding fresh water installations 16.2, 16.4, 16.6 and the corresponding sewer systems 18.2, 18.4, 18.6 leads to a significant reduction in weight.

Although the utility model has been illustrated and described in detail using preferred embodiments, the utility model is not limited to the disclosed examples, and one skilled in the art can suggest other options based thereon without departing from the scope of protection of the utility model.
