Description

Technical Field

[0001] The utility model relates to the technical field of coal mining, in particular to a main control box of a fully mechanized mining face dust source tracking spray dust reduction system. Background Art

[0002] With the increasing mechanization of coal mining, large amounts of dust are generated during mining operations. This dust is carried by airflow across the working face, eventually permeating the entire mining face and downwind chute. When coal dust accumulates to a critical point, it can easily cause major production safety accidents, such as coal dust explosions. Large amounts of floating dust are respirable, posing a significant threat to worker health. Coal dust deposited on production equipment not only accelerates wear but also degrades electrical insulation, potentially causing electrical accidents. Floating coal dust also represents a form of disordered emission loss, resulting in significant economic losses for coal mine production.

[0003] In order to supply sufficient energy to maintain social and economic development, to ensure safe production in coal mining, to protect the physical and mental health of coal mining workers, to reduce equipment wear and tear, and to improve the level of intelligent supervision, how to reduce the dust concentration in coal mines has become an important issue that urgently needs to be solved.

[0004] Existing spray dust suppression systems rely solely on sensors, lacking integrated connectivity with electrical and centralized control systems. This simple automatic control system struggles to adapt to the complex working environment of underground mines. Furthermore, existing control panels cannot accurately identify the shearer's position or track its trajectory. Design limitations limit the spray range, making it difficult for many dust suppression devices to accurately track dust sources. Furthermore, existing control panels lack a high level of intelligence.

[0005] Therefore, there is an urgent need for a main control box for a fully mechanized mining face dust source tracking spray dust reduction system. Utility Model Content

[0045] In this embodiment, a through hole is provided on the housing 7 , and a communication interface is installed in the through hole.

[0046] The communication interface includes: current input interface 8, Ethernet electrical signal interface, RS485 communication interface and antenna input interface 9;

[0047] The Ethernet electrical signal interface, RS485 communication interface, and antenna input interface 9 are cylindrical interfaces; the current input interface 8 is a trumpet-shaped interface.

[0048] In a specific embodiment, Figure 1As shown, six communication interfaces are provided, and the current input interface 8 is provided as a trumpet-shaped interface, which is compatible with cables of different diameters and provides a certain degree of adaptability and flexibility. At the same time, the current input interface 8 is usually one of the parts that are more sensitive to electromagnetic interference. The trumpet-shaped interface can adopt specific shielding materials or structures, which helps to reduce external electromagnetic interference and protect the normal operation of the system.

[0049] In addition, compared with the cylindrical interface, the trumpet-shaped interface has a unique appearance, which makes it easier for operators to quickly identify it and avoid misoperation.

[0050] Specifically, different communication interfaces can adapt to different devices, allowing the main control box to communicate with a variety of devices. For example, the Ethernet electrical signal interface supports network connection, enabling remote monitoring and control of the main control box, allowing operators to monitor the main control box's operating status and adjust operating parameters in a timely manner. Furthermore, by cooperating with the antenna input interface 9, the main control box integrates communication functions and supports the access of mobile devices, further enhancing the level of intelligence and user interaction experience.

[0051] The combination of multiple communication interfaces can meet the specific needs of different mine environments and operating processes, significantly improving the performance and application range of the main control box of the fully mechanized mining face dust source tracking spray dust reduction system in this utility model, and ensuring efficient, stable and intelligent operation.

[0052] The main control box of the fully mechanized mining face dust source tracking spray dust suppression system also includes:

[0053] Antenna 1;
