Description

Technical Field

[0001] This utility model relates to the field of early warning device technology, specifically a lightning early warning device for railway stations. Background Technology

[0002] Railway stations, as core hubs for train dispatching, marshalling, and maintenance, house a large number of sophisticated electrical devices, including signal control systems, overhead contact line power supply equipment, and communication base stations. Furthermore, stations are often located in open areas (such as suburbs and railway hubs), making them significantly more susceptible to lightning strikes than ordinary areas. Lightning can not only directly strike station equipment, causing burnouts and short circuits, but the electromagnetic pulses it generates can also interfere with signal transmission through conduction and radiation, leading to the failure of train dispatching instructions, overhead contact line tripping, and in severe cases, train delays, derailments, and other safety accidents. According to statistics, the equipment failures caused by lightning strikes in my country's railway system result in losses exceeding ten million yuan annually. Lightning disasters have become one of the key risk factors affecting the safe operation of railway stations. To reduce the harm of lightning, various lightning warning devices have emerged in existing technologies. However, their practical application in railway stations still has many shortcomings. Traditional warning devices mostly adopt a single installation method (such as only supporting ground fixing or wall mounting), which cannot adapt to the complex installation scenarios of railway stations. For example, open marshalling yards require stable ground installation, while the space around signal towers is narrow and requires wall mounting. Existing devices cannot meet the installation needs of different scenarios. Therefore, new technical solutions need to be designed to address these issues. Utility Model Content

[0018] In the actual implementation, the ground mounting rod 7 is made of seamless steel pipe, and its end is fixed to the adjusting nut 9 by argon arc welding. The bottom end of the limiting screw 10 is welded with a circular limiting block 11. During actual installation, the limiting screw 10 can be driven to rise and fall by rotating the adjusting nut 9.

[0019] In some technical solutions, the bottom end of the ground mounting rod 7 is equipped with a drive wheel 8.

[0020] In the specific implementation process, the bottom end of the ground mounting rod 7 is equipped with a drive wheel 8 through a bearing seat, and the drive wheel 8 is a polyurethane silent wheel.

[0021] In some technical solutions, the outer wall of the adjusting sleeve 14 is provided with a fixing screw hole 16, and a fixing screw 17 is screwed into the inside of the fixing screw hole 16. The end of the fixing screw 17 is fitted with the adjusting ball 15.
