Technical Field
[0001] This utility model relates to the field of fault diagnosis technology for high-voltage switchgear, specifically a diagnostic device for faults in intelligent high-voltage switchgear. Background Technology
[0002] High-voltage switchgear is a type of electrical equipment. External lines first enter the main control switch inside the cabinet, and then enter the branch control switches. Each branch circuit is set according to its needs. Intelligent high-voltage switchgear refers to a cabinet with high performance, high reliability, certain self-diagnosis and automatic control performance, and network communication capabilities. When a fault occurs in intelligent high-voltage switchgear during use, it is often necessary to diagnose its current and voltage using a multimeter.
[0003] The utility model patent with authorization announcement number CN218272438U discloses a diagnostic device for faults in intelligent high-voltage switchgear. The device can support the rod sleeve through the chassis, and limit the spring through the pull rod to prevent the spring from falling off. The spring can apply pressure to the rectangular frame and make the rack and tooth groove mesh. The rack can limit the telescopic rod through the tooth groove and maintain the height of the telescopic rod. The telescopic rod can support the support plate and maintain the height of the benchtop multimeter body.
[0004] Although the height of the benchtop multimeter can be adjusted as needed, the center of gravity of the device will also rise when the height of the benchtop multimeter is increased, which makes the diagnostic device prone to tipping over. Utility Model Content

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] This utility model provides the following technical solution:
[0024] Please see Figures 1 to 4A diagnostic device for faults in intelligent high-voltage switchgear includes a mounting base 1. Multiple self-locking casters 2 are mounted on the bottom of the mounting base 1. An adjustment mechanism 3 is mounted on the upper surface of the mounting base 1. A benchtop multimeter 4 is mounted on one side of the adjustment mechanism 3. The surface of the benchtop multimeter 4 has diagnostic lines 5, which are located inside the adjustment mechanism 3. A blocking ring 6 is fixedly connected to one end of the outer side of the diagnostic lines 5. Two diagnostic pens 7 are provided on the surface of the blocking ring 6. The adjustment mechanism 3 includes an adjustment box 301 and a transmission belt 308 fixedly connected to the upper surface of the mounting base 1. The internal rotating connection of the adjustment box 301 includes a take-up roller 302 and a first threaded rod 304. The surface of the first threaded rod 304 is threadedly connected to an internal threaded plate 305. The surface of the internal threaded plate 305 is fixedly connected to a movable plate 306. The surface of the movable plate 306 is rotatably connected to two guide rollers 307. A sleeve 312 is installed on the top of the adjustment box 301. A movable cylinder 313 is slidably connected to the inner wall of the sleeve 312. The surface of the internal threaded plate 305 is fixedly connected to a first guide plate 310. The surfaces of the adjustment box 301, the sleeve 312, and the movable cylinder 313 are all fixedly connected to a second guide plate 311.
[0025] Through the above technical solution, the take-up roller 302 and the first threaded rod 304 rotate synchronously. The rotation of the first threaded rod 304 drives the inner threaded plate 305 to move. The movement of the inner threaded plate 305 drives the moving plate 306 and the guide roller 307 to move, thereby assisting the diagnostic line 5 in winding and unwinding. The movement of the moving cylinder 313 on the inner wall of the sleeve 312 can drive the blocking ring 6 and the diagnostic pen 7 to adjust their height, thereby adapting to different diagnostic requirements. At the same time, the setting of the first guide plate 310 and the second guide plate 311 can limit the movement trajectory of the diagnostic line 5, thereby reducing the probability of the diagnostic line 5 getting tangled.
[0026] A push rod 8 is installed on one side of the mounting base 1. The surface of the push rod 8 is covered with an anti-slip sleeve 9. The push rod 8 facilitates the movement of the mounting base 1 by the staff. At the same time, the anti-slip sleeve 9 increases the friction when the staff holds the push rod 8.
[0027] The internal thread plate 305 and the movable plate 306 are slidably connected to the surface of the adjusting box 301. The diagnostic line 5 is slidably connected to the surface of the guide roller 307. The diagnostic line 5 is sleeved on the surface of the take-up roller 302. The diagnostic line 5 passes through the first guide plate 310 and multiple second guide plates 311 in sequence. By passing through the guide roller 307, the first guide plate 310 and the second guide plates 311 in sequence, the movement trajectory of the diagnostic line 5 can be better guided, and the probability of the diagnostic line 5 getting tangled can be reduced.
[0028] A servo motor 309 is installed at the bottom of the regulating box 301, and the output shaft of the servo motor 309 is fixedly connected to one end of the take-up roller 302. By setting the servo motor 309, the servo motor 309 starts its output shaft to drive the take-up roller 302 to rotate, thereby releasing or winding the diagnostic line 5.
[0029] Both the surface of the take-up roller 302 and the surface of the first threaded rod 304 are fixedly connected to pulleys 303, and the two pulleys 303 are rotatably connected by a transmission belt 308. When the take-up roller 302 rotates, it drives the first threaded rod 304 to rotate under the action of the pulleys 303 and the transmission belt 308, so that the take-up roller 302 and the first threaded rod 304 rotate synchronously.
[0030] The sleeve 312 is rotatably connected to a second threaded rod 314, and the second threaded rod 314 is fixedly connected to the top of the first threaded rod 304. The movable cylinder 313 is fixedly connected to an internal threaded ring 315, and the internal threaded ring 315 is threadedly connected to the surface of the second threaded rod 314. The rotation of the first threaded rod 304 drives the second threaded rod 314 to rotate. Under the action of the internal threaded ring 315, the rotation of the second threaded rod 314 drives the movable cylinder 313 to slide on the inner wall of the sleeve 312.
[0031] Its working principle is as follows:
[0032] Through the above technical solution, by starting the servo motor 309, the output shaft of the servo motor 309 drives the take-up roller 302 to rotate. Simultaneously, the take-up roller 302, under the action of the pulley 303 and the transmission belt 308, drives the first threaded rod 304 to rotate, thus causing the take-up roller 302 and the first threaded rod 304 to rotate synchronously. The rotation of the take-up roller 302 winds up or unwinds the diagnostic line 5. The rotation of the first threaded rod 304 drives the internal thread plate 305 to move. The movement of the internal thread plate 305 drives the moving plate 306 and the guide roller 307 to move, thereby assisting... The diagnostic line 5 is wound up and released. The rotation of the first threaded rod 304 drives the second threaded rod 314 to rotate. The rotation of the second threaded rod 314, under the action of the inner threaded ring 315, causes the moving cylinder 313 to slide on the inner wall of the sleeve 312. At this time, under the action of the first guide plate 310 and the second guide plate 311, the height of the blocking ring 6 and the diagnostic pen 7 is adjusted to adapt to different diagnostic requirements. At the same time, the setting of the first guide plate 310 and the second guide plate 311 can limit the movement trajectory of the diagnostic line 5, thereby reducing the probability of the diagnostic line 5 getting tangled.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
