Description

Technical Field

[0001] The utility model belongs to the technical field of concentrator devices, and particularly relates to a power grid concentrator that is convenient for disassembly and assembly. Background Art

[0002] With the rapid development of social economy, the concentrator is the central management device and control device of the remote centralized meter reading system, responsible for functions such as regularly reading terminal data, transmitting system commands, data communication, network management, event recording, and horizontal transmission of data. In areas with a dense number of terminals, usually to reduce communication lines, the terminals are first connected to the concentrator, and then the concentrator is connected to the communication controller of the computer through a high-speed line. Therefore, the concentrator is also an effective device for sharing lines and improving line utilization.

[0003] Chinese Patent Publication No. CN 212727293 U discloses a power grid concentrator, including a concentrator main housing. A display screen is inlaid and installed on the surface of the concentrator main housing. A lifting motor is installed inside the concentrator main housing. A lifting motor gear is fixedly installed at the front end of the lifting motor. A transmission gear is arranged above the lifting motor gear. A transmission worm is fixedly installed through the middle of the transmission gear. Transmission worm wheels are arranged on the same side at both ends of the transmission worm. A threaded sleeve is fixedly installed through the middle of the transmission worm wheel. A threaded column is movably arranged in the middle of the threaded sleeve. The bottom ends of the two threaded columns are fixedly installed with a lifting connection seat. The utility model can quickly open the device by installing a lifting connection seat, a connection port, a threaded column, and a threaded sleeve, which is convenient for connecting lines, maintaining, repairing, or replacing; however, the above device may block the heat dissipation of the device in the concentrator main housing, resulting in the inability to release heat in time, thus affecting the stable operation of the device. At the same time, devices such as the lifting motor installed inside increase the weight of the device, making the device inconvenient for installation and disassembly. When maintenance or component replacement is required, the disassembly process becomes complicated and time-consuming; therefore, it is necessary to propose a power grid concentrator that is convenient for disassembly and assembly to solve the above problems. Summary of the Utility Model

[0004] The technical problem solved by the utility model is to provide a power grid concentrator that is convenient for disassembly and assembly, has high practicability, and can be operated simply with a relatively simple structure.

Installation blocks are fixed on both the left and right sides of the concentrator main body, and fixing bolts are threadedly connected to the installation blocks. An installation seat is fixed inside the cabinet body, and the fixing bolts are threadedly connected to the installation seat. The concentrator main body and the cabinet body are threadedly connected through the fixing bolts. A plurality of wiring terminals are arranged on the lower side of the concentrator main body, and corresponding wire passing holes are provided on the cabinet body directly below the wiring terminals. A dust-proof pad is arranged in the wire passing holes. Heat dissipation holes are provided on both sides of the cabinet body, and fixing plates are fixed behind the heat dissipation holes on both sides. A cabinet door is hinged to the front side of the cabinet body.

[0006] As a further scheme of the present utility model, the fixing bolts are uniformly provided with threads, and the four groups of fixing bolts are respectively threadedly connected to the four groups of installation blocks.

[0007] As a further scheme of the present utility model, each group of installation blocks is fixed with a matching installation seat inside the cabinet body, and threaded grooves matching the fixing bolts are provided on the installation blocks and the installation seats. The installation blocks and the installation seats can be quickly fixed through the fixing bolts.

[0008] As a further scheme of the present utility model, a plurality of wiring terminals are arranged on the lower side of the concentrator main body, and a plurality of corresponding wire passing holes are provided at positions corresponding to the wiring terminals at the bottom of the cabinet body, which is convenient for connecting the concentrator main body and the cable.

[0009] As a further scheme of the present utility model, a dust-proof pad is fixed in each wire passing hole, and the dust-proof pad is made of rubber material with a groove in the middle. The dust-proof pad will surround the cable to prevent dust in the air from entering the cabinet body through the wire passing holes.

[0010] As a further scheme of the present utility model, the heat dissipation holes are inclined grooves that slope downward from the inside to the outside of the cabinet body.
