[0027] A type of train integrating a central water channel, such as Figures 1-10 As shown, it includes a second central roof 2, a third central roof 3, two first central roofs 1, and a fourth central roof 4 disposed between the two first central roofs 1; the second central roof 2 and the third central roof 3 are respectively disposed outside the two first central roofs 1; each of the two first central roofs 1, the second central roof 2, the third central roof 3 and the fourth central roof 4 is provided with a water channel and interconnected with each other, the water channels are all disposed below the crossbeams 5 of each central roof, and the electrical parts 6 of each central roof are all disposed above the crossbeams 5.

[0028] Specifically, the water paths are separately arranged in the second middle roof 2, the third middle roof 3, the two first middle roofs 1 and the fourth middle roof 4 and are interconnected, and the water paths are arranged below the cross beams 5 of the middle roofs, and the electrical part 6 is arranged above the cross beams 5, so that the water path system is integrated, the additional space reserved for laying the pipeline in the later stage of the traditional design is avoided, the carriage space is saved, the space utilization is improved, the occupation of the pipeline to the carriage space is significantly reduced through the integrated design, the internal space of the carriage is more spacious, the comfort of passengers is improved, and the fire source can be timely extinguished due to the water paths distributed throughout the train and cooperating with the smoke detector, so that the fire extinguishing system can quickly respond when a fire occurs, the fire spread is effectively controlled, the water paths are separately arranged in the middle roofs and are interconnected, the modular design makes the installation, maintenance and replacement of the water path system more convenient. If the water path in a middle roof has a problem, it can be repaired or replaced individually without affecting the normal use of other middle roofs, the electrical part 6 of each middle roof is arranged above the cross beam 5 and is separated from the water path system, so that the mutual interference between the electrical part and the water path system is avoided, the stability and safety of the system are improved, the water path system is integrated in the middle roof and does not occupy the internal space of the carriage, so that the internal space of the carriage is more clean and beautiful. At the same time, the practicability of the train is improved due to the comprehensive coverage and rapid response capability of the water path system.

[0029] As a preferred embodiment of the above-mentioned embodiment, as shown in Figures 1-10 The two first middle roof water paths 1-1 arranged in the two first middle roofs 1 are centrally symmetrically arranged on the left and right sides in the first middle roof 1.

[0030] Specifically, the first middle roof water paths 1-1 arranged in the two first middle roofs 1 are centrally symmetrically arranged on the left and right sides in the first middle roof 1, and this layout makes the distribution of water flow in the two first middle roof areas more balanced, whether the fire occurs in the left side or the right side of the first middle roof, the water flow can reach the fire point more evenly and quickly, ensuring the fire extinguishing effect, and the centrally symmetric water path makes the structure of the two first middle roofs more evenly stressed. During the running of the train, due to various vibrations and impacts of the train, this symmetrical water path layout can reduce the stress concentration caused by uneven distribution of the water path, thereby improving the stability and reliability of the entire middle roof structure, reducing the probability of water path failure due to structural problems, and most importantly, the centrally symmetric water path design has obvious advantages in installation and maintenance. During installation, the operation can be performed according to the symmetrical template, improving the installation efficiency and accuracy. During maintenance, due to the regular water path layout, the staff can more easily find the problem and repair and replace the parts. During installation of the water path, the construction personnel only need to install according to the established symmetric standard without considering the differences of the water paths at different positions. During maintenance, if a problem is found in one side of the water path, the other side of the normal water path can be referred to for troubleshooting and repair.

[0031] As a preferred embodiment of the above, as shown in Figures 1-10 The fourth middle roof waterway 4-1 arranged in the fourth middle roof 4 is symmetrically arranged across the left and right sides of the fourth middle roof 4 and is in communication with the two first middle roof waterways 1-1 symmetrically arranged in the two first middle roofs 1 at the two ends of the fourth middle roof 4.

[0032] As a preferred embodiment of the above, as shown in Figures 1-10 The two first middle roof waterways 1-1, the second middle roof waterway 2-1 arranged in the second middle roof 2 and the third middle roof waterway 3-1 arranged in the third middle roof 3 are all communicated through the tee joint 7 and led to the water injection port 8.

[0033] Specifically, the two first middle roof waterways 1-1 and the second middle roof waterway 2-1 arranged in the second middle roof 2 are all communicated through the tee joint 7 and led to the water injection port 8, which greatly simplifies the pipeline connection structure. Compared with the complex pipeline branching and connection mode, the use of the tee joint 7 makes the pipeline connection more direct and clear, reduces the length of the pipeline and the number of elbows, reduces the complexity and failure risk of the pipeline system, and at the same time avoids the delay that the water flow needs to pass through a long pipeline to reach the fire point in the traditional fire extinguishing system, greatly improving the timeliness of fire extinguishing. Moreover, by reasonably arranging the position of the water injection port 8, precise injection of different regional fire sources can be realized, and the fire extinguishing effect is improved.

[0034] As a preferred embodiment of the above, as shown in Figures 1-10 The two ends of the fourth middle roof waterway 4-1 are in communication with the two first middle roof waterways 1-1 through the ordinary joint 9.

[0035] Specifically, by using the ordinary joint 9 to communicate the two ends of the fourth middle roof waterway 4-1 with the two first middle roof waterways 1-1, great flexibility is provided for the waterway layout. According to the internal space structure of the train and the fire extinguishing demand, the position and direction of the fourth middle roof waterway 4-1 can be flexibly adjusted, so that it can better adapt to different train layouts, and at the same time can efficiently integrate multiple waterways to form an organic whole and improve the water supply efficiency of the waterway.

[0036] As a preferred embodiment of the above, as shown in Figures 1-10 The waterways are all arranged on the support below the cross beam 5 through the water pipe clamp 10.

[0037] Specifically, by using the water pipe clamp 10 to set the waterway on the bracket below the cross beam 5, a stable installation foundation is provided for the waterway. The water pipe clamp 10 can tightly fix the water pipe, effectively preventing the waterway from displacement or loosening due to factors such as vibration and bumping during train operation. Compared with the traditional installation method, such as simple binding or placement, this fixing method is more reliable, ensuring the long-term stable operation of the waterway. By installing the waterway on the bracket below the cross beam 5, the space inside the train compartment is fully utilized. The space below the cross beam 5 is usually not fully utilized.

[0038] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
