Description

Technical Field

[0001] This utility model relates to the field of lightning protection technology for computer rooms, and more specifically, to a lightning protection grounding status monitoring device for railway equipment computer rooms. Background Technology

[0002] With the rapid development of railway electrification, various advanced electrical, electronic, and communication equipment are emerging in large numbers. Railway equipment rooms are used to store these advanced electrical, electronic, and communication equipment, and it is necessary to ensure the normal operation of the internal equipment. Therefore, railway equipment rooms require lightning protection grounding monitoring to monitor the grounding status. Lightning arresters achieve their lightning protection function through grounding; when a lightning arrester is not grounded, it loses its function, necessitating monitoring of its grounding status. During equipment commissioning, grounding and ungrounding tests are required. Existing grounding devices are directly inserted into the ground, making it difficult and inconvenient to quickly adjust them for grounding or ungrounding, resulting in low work efficiency.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a lightning protection grounding status monitoring device for railway equipment rooms. The device includes a fixed grounding assembly 220, a mounting plate 211, a force transmission assembly 210, and a detector 100. The fixed grounding assembly 220 includes a first fixed assembly, a second fixed assembly, and a grounding pin 221. The grounding pin 221 is disposed between the first fixed assembly and the second fixed assembly, and is slidably connected to both the first and second fixed assemblies. The mounting plate 211 is disposed on the top of the fixed grounding assembly 220. The force transmission assembly 210 is disposed on the mounting plate 211. The force transmission component 210 is fixedly connected to the mounting plate 211, and the force transmission component 210 is pulsatorically connected to the grounding pin 221. The detector 100 is located at the bottom of the grounding pin 221 and is electrically connected to a buzzer. When grounding or disconnection from grounding is detected, an alarm will be sounded. This utility model, by setting the mounting plate 211 on the top of the fixed grounding component 220 and fixing the force transmission component 210 to the mounting plate 211, can conveniently and quickly adjust the grounding pin up and down by operating the force transmission component 210 to transmit the force to the grounding pin included in the fixed grounding component 220, thereby improving the efficiency of grounding and disconnection from ground.

[0025] like Figure 2As shown, in one specific embodiment of this disclosure, the force transmission component 210 includes a handle 218, a connecting handle 217, a worm gear assembly, a worm wheel assembly, and a transmission screw 219. The handle 218 is fixedly connected to the connecting handle 217, the connecting handle 217 is fixedly connected to the worm gear assembly, the worm gear assembly is driveably connected to the worm wheel assembly, one end of the transmission screw 219 is driveably connected to the worm wheel assembly, and the other end of the transmission screw 219 is driveably connected to the grounding pin 221. The worm gear assembly includes a worm 215 and a first mounting frame 216. The first mounting frame 216 is fixedly connected to a mounting plate 211, the worm 215 is disposed on the first mounting frame 216, and both ends of the worm 215 are hinged to the first mounting frame 216. Next, the worm gear assembly includes a worm gear 213, a second mounting frame, and a bevel gear 214. The worm gear 213 is driven by the worm 215. The second mounting frame is fixedly connected to the mounting plate 211 and is located between the worm gear 213 and the bevel gear 214. The worm gear 213 and the bevel gear 214 are driven by each other. The bevel gear 214 on the second mounting frame is driven by the bevel gear 214 on the top of the transmission screw 219. The worm 215 is driven by the hand crank 218, which drives the worm gear 213 to rotate. The worm gear 213, in conjunction with the bevel gear 214, drives the transmission screw 219 to rotate. The transmission screw 219 is threadedly driven by the grounding pin 221, enabling rapid adjustment of the grounding pin 221.

[0026] like Figure 3 As shown, in one specific embodiment of this disclosure, the first fixing component includes a side plate 212, a limiting plate 223, a slide rail 225, and a bottom plate 226. The limiting plate 223 is disposed between the side plate 212 and the slide rail 225, and the bottom plate 226 is disposed at the bottom of the limiting plate 223. The slide rail 225 is slidably connected to the grounding pin 221.

[0027] In one specific embodiment of this disclosure, limiting ears 222 are provided on both sides of the grounding pin 221. The limiting ears 222 are slidably connected to the slide rail 225. When the transmission screw 219 is threadedly driven by the grounding pin 221, the limiting ears 222 on both sides of the grounding pin 221 are limited to the slide rail 225, so that the grounding pin 221 can only slide up and down, which is convenient for insertion into the ground.

[0028] In one specific embodiment of this disclosure, the limiting plate 223 is provided with two limiting blocks 224 on the side near the side plate 212, and a sliding groove is formed between the two limiting blocks 224. The limiting plate 223 is connected to the side plate 212 through the sliding groove.

[0029] In one specific embodiment of this disclosure, at least two stops 228 are provided in the chute. The stops 228 are spaced apart along the height direction of the limiting plate 223. A handle 227 is provided on the side plate 212. One end of the handle 227 near the limiting plate 223 is positioned between two adjacent stops 228. When inserted into the ground, the handle 227 is inserted between two adjacent stops 228 to achieve a limiting position. If it needs to be removed, the handle 218 is rotated in the opposite direction. When the grounding pin 221 is loosened in the ground, the handles 227 on both sides are pulled to release the limiting position on the limiting plate 223. Pulling upwards moves the grounding pin 221 away from the ground, and it can be removed. The second insertion can be done in the opposite direction. The insertion depth of the grounding pin 221 can be adjusted to prevent repeated insertion into the same position, which would make grounding difficult.

[0030] In one specific embodiment of this disclosure, the handle 218 and the worm gear 215 are arranged in parallel, and the connecting handle 217 is arranged perpendicular to the handle 218 and the worm gear 215 respectively, which facilitates the transmission of force and reduces the labor intensity of the workers.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
