Description

Technical Field

[0001] The utility model relates to the technical field of lightning protection, in particular to a drum-shaped lightning rod for railways. Background Art

[0002] Railway lines are long and there are many stations. Railway production is a multi-professional integrated operation with high safety production requirements. The introduction of passive corona field lightning drive technology in railway lightning protection provides support for improving railway safety production capabilities. Railway-specific passive corona field lightning drive uses lightning protection technology that does not introduce lightning into the ground. It has the characteristics of large protection angle, wide protection range, and low grounding resistance requirements. The application solves the shortcomings of traditional lightning protection methods, improves the implementation progress of railway comprehensive lightning protection projects, and also greatly improves the efficiency of maintenance work after implementation. It has better protection characteristics for lightning protection projects on electrified and non-electrified railways.

[0003] When the lightning driver is in operation, the increment multiple of the corona ions above it reflects its operating efficiency. Under the same thundercloud electric field conditions, the higher the increment multiple of the corona ion concentration above the protected target, the better the protection effect. The lightning rod is the main emission mechanism of corona ions. The existing lightning rod of the lightning driver is a pointed cylinder. The surface area of ​​the pointed cylindrical structure lightning rod is small, and the corona ion aggregation ability of the structure is weak, resulting in low operating efficiency. Under the premise of exerting the basic functions of the lightning driver, the structure of the lightning rod is optimized so that the increment multiple of the corona ions is increased when the equipment is running, so as to improve the operating efficiency and response time of the equipment. Utility Model Content

[0004] The purpose of the utility model is to provide a drum-type lightning rod for railways, which solves the technical problem that the existing lightning rod has a small surface area, resulting in a weak ability to gather corona ions. The lightning rod of the utility model is a drum-type structure, which increases the surface area of ​​the lightning rod, can better gather corona ions, and increases the energy storage part without affecting the tip effect, thereby maximizing the corona ion carrying capacity of the lightning rod. Under the same thundercloud electric field conditions, the multiple of the corona ion concentration increment above the protected target is increased, which is conducive to the corona ions generated by the lightning driver to form a charge protection layer on the upper layer of the protected target, thereby improving the lightning protection capability of the corona field lightning driver.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A drum-type lightning rod for railways comprises a lightning rod body, wherein the lightning rod body comprises an energy storage end and a discharge end, wherein one end of the energy storage end is connected to one end of the discharge end, and the other end of the energy storage end is provided with a connecting piece, and the energy storage end is provided with a drum-type structure.

[0007] Furthermore, the energy storage end and the discharge end are integrally formed, the length of the energy storage end is set to 2 / 3 of the lightning rod main body, and the length of the discharge end is set to 1 / 3 of the lightning rod main body.

[0008] Furthermore, a thread is arranged on the outer side of the connecting piece, a locking nut is arranged on the connecting piece, and the locking nut is threadably connected to the connecting piece.

[0009] Furthermore, the other end of the discharge end is provided with a pointed end.

[0010] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0011] The utility model provides an energy storage end on the lightning rod, and the energy storage end is configured as a drum-shaped structure with a large surface area, which can better gather corona ions.

The energy storage end 2 is configured as a drum-type structure to increase its surface area, which can better gather corona ions, increase the energy storage part without affecting the tip effect, and maximize the corona ion carrying capacity of the lightning rod. The outer curve of the drum-type structure of the energy storage end 2 can be a circular curve, an elliptical curve or a catenary curve, and the energy storage end 2 can be configured as a hollow structure, which can reduce the weight of the lightning rod.
