Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, in particular to a general low-voltage switch cabinet for mining. Background Art

[0002] The switch cabinet is an electrical equipment. The external line of the switch cabinet first enters the main control switch inside the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. Some also have high-voltage and low-voltage room switch cabinets, with high-voltage busbars, such as power plants, etc. Some also have low-frequency load shedding to protect the main equipment. Low-voltage switch cabinets are also usually needed in the development of underground mineral resources.

[0003] After searching, it was found that the publication number was CN216312449U, and the name was a general low-voltage switch cabinet for mining. The application proposed that a traditional switch cabinet is generally provided with a base at the bottom, but the base is prone to fall off or damage during use, and the staff needs to maintain and replace the base in time. The traditional installation method between the base and the switch cabinet generally requires installation through multiple sets of bolts. This method is relatively cumbersome to operate and reduces the working efficiency of the device. By setting a sleeve, a block, a rack plate, a sliding groove, a driving gear, a sliding block and a reset spring, the two sets of rack plates can be driven to move in the opposite direction inside the sliding groove by rotating the driving gear. At this time, the reset spring is squeezed and compressed, and drives the block to separate from the inside of the sleeve. At this time, the staff can replace the base with the switch cabinet. This method is more convenient when disassembling the base, which improves the maintenance efficiency of the device and It also facilitates the normal use of the device. At the same time, by setting a fixed column, a movable column, a protective plate, a movable sleeve, a threaded rod and a handle, the threaded rod can be driven to rotate by rotating the handle, and the movable sleeve can be driven to move vertically back and forth under the extrusion of the thread, thereby driving the protective plate to move up and down, thereby achieving a better adjustment effect. The protective plate can achieve a protective effect and ensure that dust does not fall on the top of the switch cabinet, thereby ensuring the cleanliness of the switch cabinet during use. The above method is more convenient to operate and improves the use effect of the device. However, when the application is actually used, since the gear is located under the base, the staff needs to extend their hands under the base to operate, which is not convenient enough. At the same time, it is not convenient to position the switch cabinet during installation, which affects the convenience of use. In addition, when the staff lifts the protective plate, the staff also needs to extend their hands between the protective plate and the top of the switch cabinet, which is not convenient enough.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

The positioning rod 7 improves the installation accuracy of the main body 1 of the low-voltage switch cabinet for mining, facilitates alignment with the L-shaped plate 4, and improves the convenience of installation. The utility model is convenient. When disassembling the main body 1 of the mining low-voltage switch cabinet, it is only necessary to rotate the hand wheel 9 in the opposite direction to separate the L-shaped plate 4 from the main body 1 of the mining low-voltage switch cabinet, and then the main body 1 of the mining low-voltage switch cabinet can be moved up and removed. The hand wheel 9 located on the side of the base 2 greatly facilitates the operation of the staff and improves the convenience of installation and use. When the ceiling 10 needs to be raised or lowered, the valve 15 can be opened. The staff only needs to move the ceiling 10 up and down to change the height of the ceiling 10. After reaching the adjusted height, it is only necessary to close the valve 15 to prevent the air inside the outer cylinder 11 from circulating, and the inner rod 12 can be locked to lock the height of the ceiling 10. Since the outer cylinder 11 is installed on the top edge of the main body 1 of the mining low-voltage switch cabinet, it is more convenient for the staff to operate, which further improves the convenience of use.
