[0041] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0042] The embodiment of the utility model proposes a sub-control box for a comprehensive mining face dust source tracking spray dust reduction system. In order to solve the technical problem that intelligent control cannot be performed in the existing technology and an external ball valve needs to be installed to realize the spray function, the sub-control box adopts a T-type four-way valve and electric execution built into the sub-control box, and a PCB circuit board is set at the same time, thereby realizing the intelligent requirements and improving the intelligent automation of the sub-control box.

[0043] To better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0044] Specific embodiment description part

[0045] Example 1

[0046] See also Figure 1 The utility model provides a sub-control box for a fully mechanized mining face dust source tracking spray dust suppression system, comprising:

[0047] Housing 11, communication interface 1, PCB circuit board 2 and T-shaped cross 3.

[0048] The PCB circuit board 2 and the T-shaped cross-connection 3 are fixed inside the housing 11; a mounting interface hole is provided on the housing 11, and the communication interface 1 is installed in the mounting interface hole.

[0049] The main line of the T-shaped cross 3 is connected to the main water supply line through the first through hole 7 on the shell 11, and the three branches of the T-shaped cross 3 output water through the second through hole 8, the third through hole 9 and the fourth through hole 10 on the shell 11 respectively.

[0050] The PCB circuit board 2 is connected to the electric actuator 4 by wires.

[0051] In this embodiment, the PCB circuit board 2 serves as a control core and is connected to the electric actuator 4 by wires for receiving signals, processing data, and controlling the action of the electric actuator 4 to achieve precise spray control.

[0052] In this embodiment, the communication interface 1 includes:

[0053] Antenna input interface 5, Ethernet electrical signal interface and RS485 communication interface.

[0054] The antenna input port 5, Ethernet electrical signal port and RS485 communication port are all cylindrical ports.

[0055] By setting up a variety of communication interfaces 1, the specific needs of different mine environments and operating processes can be met.

[0056] In this embodiment, the sub-control box of the fully mechanized mining face dust source tracking spray dust suppression system also includes:

[0057] Electric actuator 4;

[0058] There are three electric actuators 4 , and each electric actuator 4 is installed at three branches of the T-shaped cross 3 .

[0059] By cleverly combining the electric actuator 4 with the T-type four-way 3, the sub-control box of the fully mechanized mining face dust source tracking spray dust reduction system of this embodiment realizes automated and intelligent control, which not only improves the dust reduction effect, but also reflects the efficient use of resources and environmental friendliness.

[0060] In the specific implementation process, a redundant design is also added to the electric actuator 4. Once the electric actuator 4 fails, the backup electric actuator 4 can automatically take over to ensure stable operation.

[0061] In this embodiment, the sub-control box of the fully mechanized mining face dust source tracking spray dust suppression system also includes:

[0062] Antenna 6;

[0063] Antenna 6 is an external omnidirectional antenna.

[0064] The antenna 6 is connected to the PCB circuit board 2 via the antenna input interface 5 .

[0065] By arranging the antenna 6 in conjunction with the antenna input interface 5 , the sub-control box can integrate wireless communication functions and support access to mobile devices, thereby further improving the intelligence level and user interaction experience.

[0066] In this embodiment, the sub-control box also includes:

[0067] heat dissipation device;

[0068] The heat dissipation device includes: a heat sink and a heat dissipation fan.

[0069] The heat sink is fixed on the PCB circuit board 2 and is in close contact with the PCB circuit board 2 ; the fan is fixed inside the housing 11 , with the wind direction facing the PCB circuit board 2 .

[0070] In practice, the heat sink is typically made of a material with excellent thermal conductivity and maintains close contact with the PCB 2, ensuring rapid heat transfer. The cooling fan is designed to blow directly toward the PCB 2, ensuring the wind effectively covers the heat-generating area and rapidly dissipating heat. Furthermore, the size and speed of the cooling fan are determined based on environmental conditions, the power consumption of the PCB 2, and the operating temperature.

[0071] In this embodiment, the housing 11 is a flameproof housing, and the protection grade is Ex d IIC T6.

[0072] Protection grade Ex d IIC T6 means it is suitable for explosive gas environments, adopts flameproof and explosion-proof structure, is suitable for Class II Class C gas environments, temperature group is T6, and the maximum surface temperature of the equipment does not exceed 85°C.

[0073] Sealing gaskets are provided at each connection of the T-shaped cross 3; the sealing gaskets are O-rings, which are tightly attached to each connection of the T-shaped cross 3;

[0074] The size of the sealing gasket is the same as that of the T-type cross 3 connection.

[0075] The sub-control box of the fully mechanized mining face dust source tracking spray dust suppression system also includes:

[0076] LED indicator light;

[0077] The LED indicator light is fixed to the outside of the housing 11 and is connected to the PCB circuit board 2 via the communication interface 1.

[0078] In the specific implementation process, the LED indicator light has waterproof and dustproof functions. When the LED indicator light is green, it means that the sub-control box is running. When it is red, it means that the sub-control box has a fault or is not in operation.

[0079] By setting LED indicator lights, operators can understand the status of the sub-control box and quickly determine whether the dust source tracking spray dust reduction system on the fully mechanized mining surface is operating normally.

[0080] In this embodiment, the electric actuator 4 is an electric ball valve;

[0081] The electric ball valve comprises an electric drive device and a ball valve body; the electric drive device and the ball valve body are fixedly connected via a connecting shaft.

[0082] The electric ball valve inside the sub-control box precisely controls the opening and closing of the water flow in the pipeline and adjusts the flow rate according to the instructions issued by the PCB circuit board 2. This ensures precise control of the water volume sprayed during the dust suppression process, ensuring dust suppression effectiveness while avoiding water waste. Furthermore, the electric actuator 4 is configured as an electric ball valve, which starts quickly and can open or close the valve in a very short time. The electric ball valve also provides excellent sealing performance when closed, effectively preventing water leakage and ensuring the stable operation of the sub-control box.

[0083] The utility model provides a sub-control box for a comprehensive mining face dust source tracking spray dust reduction system, which realizes an intelligent and automated control dust reduction function by integrating key components such as a PCB circuit board 2, a T-type four-way valve 3 and an electric actuator 4; its beneficial effects are reflected in: significantly improving the dust reduction efficiency and reliability, and achieving efficient resource utilization and reduced energy consumption through automated operation combined with the control logic of the PCB circuit board; the high protection grade housing 11 of the sub-control box also ensures safe and stable operation in a mine environment, providing effective support for coal mine safety and environmental protection.
