Description

Technical Field

[0001] This utility model belongs to the field of alarm device technology, and in particular relates to a train alarm device. Background Technology

[0002] As one of the core devices for ensuring the safe operation of trains, train alarms occupy an indispensable position in the modern railway transportation system. With the continuous expansion of the railway network and the rapid development of train technology, train speeds have increased significantly and transportation frequency has become more frequent, which has placed more stringent requirements on the performance, reliability and adaptability of train alarms.

[0003] In practical applications, existing train sirens have revealed many problems that urgently need to be addressed. From a structural design perspective, many sirens lack a reasonable internal layout, with components arranged haphazardly. This not only weakens the overall performance of the sirens but also greatly increases the difficulty of daily maintenance and troubleshooting. More importantly, some sirens are not robust enough and are prone to loosening or even damage under the vibration and impact generated by trains during long-term operation, seriously threatening the continuous and stable operation of the sirens.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4As shown, a train alarm device includes a housing 1, a top cover 2, a bottom cover 7, and fixing components. The housing 1 serves as the main structure, with the top cover 2 installed on its top and the bottom cover 7 installed on its bottom. The top cover 2 has a unique design, consisting of a cover plate 16 and an upper cover 18. This design ensures structural stability, facilitates the shielding of internal components to prevent corrosion from external factors, and is made entirely of metal to ensure its service life.

[0028] On the top of the cover 18, a three-in-one antenna 3 and a top alarm light 4 are installed. The three-in-one antenna 3 integrates multiple communication functions to ensure that the train alarm device can stably receive and send signals. The top alarm light 4 is used to emit a clear visual alarm signal in emergency situations. To facilitate the installation and use of the three-in-one antenna 3 and the top alarm light 4, a clearance hole 17 adapted to them is opened on the top of the cover plate 16.

[0029] One side of the housing 1 is equipped with a side alarm light 5 and a speaker 6, used to emit visual and audible alarm signals from the side to alert surrounding personnel. On the other side of the housing 1, from left to right, are arranged a 433MHz antenna 10, a network indicator light 11, a Beidou positioning indicator light 12, an aviation socket 13, a power switch 14, and a grounding point 15. These components are responsible for different functions; for example, the 433MHz antenna 10 is used for wireless communication, the network indicator light 11 displays the network connection status, the Beidou positioning indicator light 12 displays the positioning status, the aviation socket 13 is used to connect external devices, the power switch 14 controls the power supply to the entire device, and the grounding point 15 is used for grounding protection.

[0030] For securing the components, four bolts 21 are used to fix the top cover 2 and the bottom cover 7 to the outer casing 1. Specifically, countersunk holes 19 adapted to the bolts 21 are provided at the four corners of the top of the top cover 18, and threaded holes for threaded connection with the bolts 21 are provided at the top of the bottom cover 7. During installation, the bolts 21 are passed through the countersunk holes 19 and threadedly connected to the threaded holes, thereby securing the top cover 2 and the bottom cover 7. At the same time, the countersunk holes 19 ensure that the top of the bolts 21 does not protrude from the top of the top cover 18.

[0031] To further improve the stability and accuracy of the fixing, sleeves 20 are provided on the inner walls of the four corners of the outer casing 1. The bolts 21 will be located inside the sleeves 20 during installation, which not only positions the bolts 21, but also prevents them from loosening or shifting during long-term use.

[0032] To ensure the airtightness of the housing 1, sealing strips 23 adapted to the housing 1 are provided on the adjacent sides of the upper cover 18 and the bottom cover 7. The sealing strips 23 can effectively prevent moisture and dust from entering the interior of the housing 1, thereby protecting the internal components from damage.

[0033] Regarding the connection between the cover plate 16 and the upper cover 18, a cavity 22 adapted to the upper cover 18 is provided at the bottom of the cover plate 16. During installation, the upper cover 18 is embedded in the cavity 22 and fixed to the cover plate 16 by adhesive. This design ensures a stable connection between the cover plate 16 and the upper cover 18, and also facilitates the maintenance and replacement of the internal components of the upper cover 18.

[0034] Finally, extension ears 8 are provided on both sides of the bottom cover 7. The top of each extension ear 8 has a mounting hole 9, facilitating the installation of the entire train alarm device housing on the train. By passing bolts or other fasteners through the mounting holes 9 and connecting them to the mounting position on the train, a secure installation of the entire device can be achieved.

[0035] The usage process and working principle of this utility model technical solution are as follows: During installation, first install the side alarm light 5 and speaker 6 on one side of the housing 1, then install the 433MH antenna 10, network indicator light 11, Beidou positioning indicator light 12, aviation socket 13, power switch 14 and grounding point 15 on the other side of the housing 1, and then install the circuit board inside the housing 1 and connect it to the side alarm light 5, speaker 6, 433MH antenna 10, network indicator light 11, Beidou positioning indicator light 12, aviation socket 13, power switch 14 and grounding point 15;

[0036] After the connection is completed, place the outer shell 1 on the bottom cover 7, then install the three-in-one antenna 3 and the top alarm light 4 on the top cover 18 and connect them to the internal circuit board. Then place the top cover 18 on the outer shell 1 and insert the bolt 21 into the countersunk hole 19 and the sleeve 20 to make it threadedly connected to the bottom cover 7. Finally, glue the cover plate 16 to the top cover 18.
