Description

Technical Field

[0001] This utility model belongs to the field of fault diagnosis switch technology, specifically a heat-dissipating fault diagnosis switch based on train control data communication. Background Technology

[0002] A switch is a network device specifically designed for use in network systems. It enables real-time monitoring, diagnosis, and early warning of network communication status, equipment operation, and potential faults. It combines the data forwarding capabilities of a traditional switch with fault detection, diagnosis, and management functions, primarily used to improve network reliability and maintainability.

[0003] After prolonged use, switches generate a large amount of heat inside. If this heat is not dissipated quickly, it will cause irreversible damage to the internal electronic components. Currently, most switches use ventilation holes or fans for heat dissipation. Ventilation holes are not very effective, and because fans are fixed inside the switch, only some areas of the electronic components can be effectively cooled. The electronic components that control the fan's airflow cannot be effectively cooled, and after long-term operation, these components are easily damaged. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a heat-dissipating fault diagnosis switch based on train control data communication, which features uniform heat dissipation. This invention not only solves the internal heat dissipation problem of the switch but also addresses the issue of uneven heat dissipation in different areas of the internal components due to the large internal space of the switch. This avoids the problem of parts in previously well-ventilated areas burning out due to uneven heat dissipation, and also reduces the number of fans required.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat-dissipating fault diagnosis switch based on train control data communication, comprising a switch housing, a plurality of fixing blocks fixedly disposed on the outer side of the switch housing, a servo motor fixedly disposed on the outer side of the fixing blocks, a threaded rod fixedly disposed at the end of the main shaft of the servo motor, a threaded sleeve threadedly connected to the outer side of the threaded rod, a rack fixedly disposed on the outer side of the threaded sleeve, a gear meshing with the outer side of the rack, a fixing sleeve fixedly disposed on the outer side of the gear, and a fan body fixedly disposed on the outer side of the fixing sleeve.

[0006] Preferably, a connecting shaft is fixedly installed inside the fixed sleeve, and both ends of the connecting shaft are rotatably fixed seats, which are fixedly connected to the switch housing.

[0007] Preferably, bearings are rotatably provided on the outer sides of both sides of the connecting shaft, and the bearings are fixedly connected to the fixed base.

[0008] Preferably, a protective cover is fixedly provided on the outer side of the fixing sleeve, and the fan body is located inside the protective cover.

[0009] Preferably, protective covers are fixedly installed on both sides of the switch housing, and the servo motor is located inside the protective covers.

[0010] Preferably, a plurality of interfaces are fixedly provided on the rear side of the switch housing, a connecting cable is fixedly provided on the rear side of the interfaces, and an internal component is fixedly provided on the other side of the connecting cable.

[0011] Preferably, an indicator light is fixedly installed on the rear side of the switch housing, and a display screen is fixedly installed on the front side of the switch housing, and the display screen is electrically connected to the indicator light.

[0012] Preferably, the top surface of the switch housing has multiple elongated heat dissipation holes, and the outer side of the switch housing is fixedly provided with multiple fixing feet.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention utilizes the coordinated operation of specific components. A servo motor drives the threaded rod inside the fixed block to rotate, which in turn drives the threaded sleeve to slide. The threaded sleeve then drives the rack to slide, which in turn drives the gear to rotate. The gear then drives the fixed sleeve and the fan body to rotate, thereby dissipating heat from the internal components. Through this series of continuous actions, cool air can flow omnidirectionally and without dead angles inside the switch, solving the heat dissipation problem inside the switch, significantly reducing the overall temperature, and ensuring the stable operation of the switch.

A fan body 9 is fixedly installed on the outer side of the fixing sleeve 8. The servo motor 3 drives the threaded rod 4 to rotate, which in turn drives the threaded sleeve 5 to slide. The threaded sleeve 5 then drives the rack 6 to slide, which in turn drives the gear 7 to rotate. The gear 7 then drives the fixing sleeve 8 and the fan body 9 to rotate, thereby dissipating heat inside the switch housing 1. This not only solves the problem of internal heat dissipation in the switch but also addresses the problem of uneven heat dissipation in different areas of the internal components due to the large internal space of the switch. This avoids the problem of parts in the original heat dissipation areas being burned out due to uneven heat dissipation, and also saves on the number of fans required.

[0024] Specifically, a connecting shaft 12 is fixedly installed inside the fixed sleeve 8. Both ends of the connecting shaft 12 are rotated fixed seats 10 on the outer side, and the fixed seats 10 are fixedly connected to the switch housing 1.

[0025] Furthermore, bearings 21 are rotatably mounted on both sides of the connecting shaft 12, and the bearings 21 are fixedly connected to the fixed seat 10. The bearings 21 can reduce the friction when the connecting shaft 12 rotates.

[0026] Furthermore, a protective cover 11 is fixedly installed on the outside of the fixed sleeve 8, and the fan body 9 is located inside the protective cover 11. The protective cover 11 can protect the fan body 9 and prevent it from colliding with other components.

[0027] It is worth noting that protective covers 13 are fixedly installed on both sides of the switch housing 1, and the servo motor 3 is located inside the protective cover 13. The protective cover 13 can protect the internal operating parts and also protect people outside.

[0028] It is worth noting that multiple interfaces 15 are fixedly installed on the rear side of the switch housing 1, and connecting lines 19 are fixedly installed on the rear side of the interfaces 15. An internal component 20 is fixedly installed on the other side of the connecting lines 19. The interfaces 15 are used to connect the train's communication devices and train control equipment, and data is aggregated through the internal component 20.

[0029] It is worth mentioning that an indicator light 16 is fixedly installed on the rear side of the switch housing 1, and a display screen 14 is fixedly installed on the front side of the switch housing 1. The display screen 14 is electrically connected to the indicator light 16. The indicator light 16 is used to display the port connection status, data transmission status and fault alarms. This information will then be displayed on the display screen 14.

[0030] It is worth emphasizing that the top surface of the switch housing 1 has multiple elongated heat dissipation holes 17, and the outer side of the switch housing 1 is fixedly provided with multiple fixing feet 18. The elongated heat dissipation holes 17 are used for daily heat dissipation, and the fixing feet 18 are used for the installation of the switch housing 1.

[0031] Among them, the servo motor 3 is existing technology and will not be described in detail; at the same time, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail; the "front, back, left, and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0032] Working principle:

[0033] When using a heat-dissipating fault diagnosis switch based on train control data communication, it is first fixed inside the train's cabinet using mounting feet 18, thus forming a complete network system with other signaling equipment. Then, the switch housing 1 is connected to the train's communication devices and train control equipment via interface 15. Interface 15 is then connected to internal components 20 via connecting cable 19. Indicator lights 16 display port connection status, data transmission status, and fault alarms. Display screen 14 shows various data from the connection points. When unnecessary braking of the train occurs, the fault cause is located, specifically whether it is a communication problem or a train control equipment problem. The detected information is then fed back to display screen 14, which also displays internal problems to determine when to activate the heat dissipation structure. After prolonged use, the switch generates a large amount of heat internally, which can cause problems with the switch. Negative impacts, and the heat dissipation vent 17 is used to remove this heat. If the heat dissipation effect of the heat dissipation vent 17 is not ideal, the system automatically turns on the switch of the servo motor 3 inside the protective cover 13. The servo motor 3 drives the threaded rod 4 inside the fixed block 2 to rotate. The threaded rod 4 drives the threaded sleeve 5 to slide. The threaded sleeve 5 drives the rack 6 to slide. The rack 6 drives the gear 7 to rotate. The gear 7 drives the fixed sleeve 8 and the fan body 9 to rotate, thereby dissipating heat from the internal component 20. The protective cover 11 is used to protect the internal fan body 9. The fixed seat 10 is used to fix the connecting shaft 12. The bearing 21 is used to reduce the friction when the connecting shaft 12 rotates. This utility model not only solves the problem of heat dissipation inside the switch, but also solves the problem of uneven heat dissipation in different areas of the internal components due to the large internal space of the switch. It avoids the problem of parts in the original heat dissipation area being burned due to uneven heat dissipation. It also saves the number of fans used.
