Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage cabinets, in particular to a low-voltage cabinet with a collision power-off function. Background Art

[0002] As the name suggests, high and low voltage switchgear is equipment for connecting high-voltage or low-voltage cables. Generally, power supply bureaus and substations use high-voltage cabinets, which are then stepped down by transformers and then transferred to low-voltage cabinets. The low-voltage cabinets are then transferred to distribution boxes for various electricity users. What is inside is nothing more than some protective devices such as switches and circuit breakers assembled into one electrical equipment.

[0003] Many existing high and low voltage cabinets are used outdoors because the outdoor environment is more complex and changeable. If the high and low voltage cabinets are hit at a relatively long distance, the wires inside the cabinet may break or the cabinet may be damaged, exposing the internal wires. At this time, if passers-by or staff who are unaware of the situation come forward to check, electric shock accidents may occur, posing a threat to people.

[0004] For example, Chinese patent CN116169566A discloses a high and low voltage cabinet with a power-off function by impact. The first threaded rod is driven to rotate by twisting the twist cap. The rotation of the first threaded rod drives the cover body to move downward to cover and fix the metal ball to prevent it from displacement. The high and low voltage cabinet body is then moved to a suitable position and placed. The cover body is then separated from the metal ball. When the high and low voltage cabinet body collides, the metal ball will fall out from the inside of the tray and fall on the force plate. At the same time, the force plate will move downward to squeeze the sensor. The sensor triggers the alarm to emit a high-decibel alarm sound to achieve the function of warning and calling for help. At the same time, the downward movement of the force plate will drive the pull rope to move downward. The movement of the pull rope drives the contact piece to move downward, so that the contact piece is separated from the two contact heads to achieve the effect of power off.

[0005] However, the device has a complex structure during use. When power supply needs to be restored, the position and tension of the pull cord need to be adjusted, which is inconvenient to use.

[0006] For this reason, we urgently need to provide a low-voltage cabinet with a power-off impact function. Utility Model Content

The two contacting contacts 306 are separated by the insulating plate 303, so that the low-voltage cabinet 1 is powered off. The second spring 304 is fixedly installed in the cavity 6. On the front and rear sides of the lower end of the interior, the damping rod 305 is installed inside the front and rear second springs 304 to prevent the contact 306 from shaking back and forth under the action of the second spring 304. The contact 306 is installed at one end of the damping rod 305. The placement table 307 is arranged at the upper end of the cavity 6. The fixing rod 308 is fixedly installed on the left and right sides of the placement table 307. The end of the fixing rod 308 away from the placement table 307 is fixedly connected to the inner wall of the cavity 6. The placement table 307 is fixed inside the cavity 6 by the fixing rod 308, and the iron ball 309 is installed on the top of the placement table 307.

[0031] The fixing unit includes a threaded rod 401, a ball cover 402, a bearing 403 and a limit rod 404. The threaded rod 401 is threadedly connected to the top of the low-voltage cabinet 1 and is located above the cavity 6. The ball cover 402 is installed at the bottom of the threaded rod 401.

The upper support rod 501 is provided with an internal thread, and the lower support rod 502 is provided with an external thread. When the low-voltage cabinet 1 is installed, if the low-voltage cabinet 1 is unstable due to uneven ground, the lower support rod 502 is rotated to be threadedly connected with the upper support rod 501, so that the lower support rod 502 drives the base 503 to move up and down, so that the low-voltage cabinet 1 remains level, and the low-voltage cabinet 1 is prevented from shaking and causing the iron ball 309 to fall, causing power outages.

[0034] Embodiment three:

[0035] On the basis of the first embodiment: a groove is provided on the upper surface of the placement table 307, and the iron ball 309 is installed inside the groove, so that the iron ball 309 is easily placed through the groove and prevented from rolling randomly.

[0036] When in use, the threaded rod 401 is rotated to drive the ball cover 402 to move downward to cover the iron ball 309 to prevent the iron ball 309 from shaking, and then the low-voltage cabinet 1 is moved to the desired position. When the low-voltage cabinet 1 is unstable due to the uneven ground, the lower support rod 502 is threadedly connected to the upper support rod 501 by rotating the lower support rod 502 to drive the base 503 to move up and down to keep the low-voltage cabinet 1 horizontal. The threaded rod 401 is rotated again until the ball cover 402 is away from the iron ball 309. When the low-voltage cabinet 1 is hit, the iron ball 309 09 falls from the top of the placement table 307 to the top of the load-bearing plate 302, and pushes the load-bearing plate 302 to squeeze the first spring 301 downward, so that the insulating plate 303 is inserted between the other contacts 306, so that the two contacts 306 are separated, thereby cutting off the power supply to the low-voltage cabinet 1. When the power supply needs to be restored, just open the cabinet door 2 and place the iron ball 309 on the top of the placement table 307 again. The load-bearing plate 302, pushed by the first spring 301, drives the insulating plate 303 to move upward, so that the two contacts 306 are in contact, thereby restoring the power supply to the low-voltage cabinet 1.
