[0025] The embodiments of the present disclosure will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary only for explaining the present disclosure and should not be construed as limiting the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0026] As Figure 1 and Figure 3 shown, an embodiment of the present disclosure proposes a mine intrinsically safe monitoring substation, including: a housing 1, a shock absorption assembly 2, a circuit board 3, a main control module (not shown in the figure), a communication module (not shown in the figure), an input / output module (not shown in the figure), and an air duct 4. Among them, the housing 1 is arranged in the mine roadway, the shock absorption assembly 2 is arranged in the housing 1, the circuit board 3 is arranged on the shock absorption assembly 2, the main control module, the communication module, and the input / output module are respectively arranged on the circuit board 3, and the input / output ends of the input / output module extend outside the housing 1. The communication end of the main control module is connected to the first communication end of the communication module, the second communication end of the communication module is connected to the communication end of the input / output module, the air duct 4 is arranged in the housing 1, and the air inlet end and the air outlet end of the air duct 4 respectively extend outside the housing 1, and the air inlet end of the air duct 4 is arranged opposite to the wind direction of the roadway.

[0027] It can be understood that since the communication end of the main control module is connected to the first communication end of the communication module, and the second communication end of the communication module is connected to the communication end of the input / output module, the main control module can use the communication module and the input / output module to communicate with external devices, thus facilitating the realization of the mine monitoring function. Moreover, the main control module, the communication module, and the input / output module are integrated on the same circuit board 3, thereby achieving direct connection between modules while reducing the volume of the substation, avoiding problems such as large volume and easy oxidation and failure of cable nodes. At the same time, in cooperation with the shock absorption component 2 and the air duct 4, shock absorption and heat dissipation are achieved, thus ensuring high equipment reliability, maintenance efficiency, and system response speed in the construction of mine intelligence.

[0028] It should be noted that the main control module, the communication module, and the input / output module are used to realize the monitoring function of the substation. Among them, the specific types of the main control module, the communication module, and the input / output module can be set according to actual needs, and there is no limitation on this. For example, modules such as the main control module, the communication module, the input / output module, and the human-computer interaction module optimize the signal routing through multi-layer PCB layout, and use a unified bus (such as SPI, I2C) to achieve high-speed communication between modules. Specifically, the main control module (such as the main control chip) directly drives the communication module (such as the RS485 transceiver) through the built-in protocol stack, eliminating the external conversion circuit. The substation in this embodiment can significantly reduce the connection nodes and improve the system stability through integration and interface standardization.

[0029] The main control module may include: the main control chip and its basic function circuits, which are the core part of the underground substation. The main control chip is responsible for the control and data processing of the entire substation, while the crystal oscillation circuit in the basic function circuits provides the clock signal required for the operation of the substation to ensure that the substation can operate according to the predetermined timing. The reset circuit in the basic function circuits is used to realize the reset function of the main control chip. When the substation has an abnormality or needs to be restarted, the reset circuit can ensure that the main control chip returns to the initial state.

[0030] The input / output module may include: a general analog quantity module and a general switch quantity module. For example, the general analog quantity input module is responsible for receiving analog quantity signals such as gas and wind speed, and these signals need to be conditioned before being input to the main control chip for processing; the general switch quantity input module is used to monitor the operating status of underground equipment, the opening and closing of air doors, etc., providing an important basis for safe production.

[0031] The heat dissipation of traditional sub-stations relies on fans or heat sinks. However, fans are prone to failure due to dust blockage, and heat sinks have low efficiency due to space limitations. The sub-station in this embodiment adopts the air duct 4 structure that penetrates the housing 1, utilizes the natural air flow in the roadway to form a chimney effect, and forces the air flow to flow along the air duct 4 to cool the sub-station. The specific type of the air duct 4 can be set according to actual needs, and there is no limitation on this. For example, the air duct 4 is a through pipe structure, and the natural wind in the roadway passes through the air duct 4 to take away the heat inside the housing 1 to achieve the purpose of heat dissipation.

[0032] The shock-absorbing component 2 can effectively improve the shock-absorbing performance of the circuit board 3 and extend the underground service life of the sub-station. The specific type of the shock-absorbing component 2 can be set according to actual needs, and there is no limitation on this.

[0033] In some embodiments, the inner wall of the air duct 4 is provided with a corrugated structure, and the air duct 4 is distributed in a serpentine shape inside the housing 1.

[0034] It can be understood that the air duct 4 adopts a corrugated inner wall to enhance heat exchange through the turbulence effect, and the path of the air duct 4 is distributed in a serpentine shape, thereby prolonging the air flow residence time, and thus effectively improving the heat dissipation efficiency of the sub-station.

[0035] It should be noted that the sub-station in this embodiment adopts passive air duct 4 heat dissipation. Through the corrugation of the air duct 4 cross-section and path optimization, on the one hand, the heat dissipation area is increased, and on the other hand, the contact time is prolonged, thereby significantly improving the heat dissipation efficiency without additional energy consumption and ensuring the safe and stable operation of the sub-station.

[0036] Among them, while the air duct 4 is distributed in a serpentine shape, it can also be arranged as a whole in an inclined downward manner to avoid dust accumulation in the roadway.

[0037] In some embodiments, the diameter of the air inlet end of the air duct 4 linearly increases in the direction away from the air outlet end.

[0038] It can be understood that since the diameter of the air inlet end of the air duct 4 linearly increases in the direction away from the air outlet end, a funnel-shaped structure is formed at the air inlet end of the air duct 4. Based on the principles of fluid mechanics and heat exchange, the air inlet end of the funnel-shaped structure can significantly reduce the air temperature entering the air duct 4, thereby effectively improving the heat dissipation efficiency of the sub-station.

[0039] In some embodiments, the sub-station further includes: a heat storage module, the heat storage module is arranged inside the housing 1, and the heat storage module abuts between the main control module and the air duct 4, and a phase change material is arranged inside the heat storage module.

[0040] It can be understood that since the heat storage module abuts between the main control module and the air duct 4, and a phase change material is provided in the heat storage module, the heat storage module can quickly absorb the heat of the main control module by using the phase change material and gradually release the absorbed heat into the air duct 4. Thus, the peak temperature of the main control module is effectively reduced, avoiding performance degradation or damage caused by instantaneous high temperature, and further improving the operation stability of the main control module.

[0041] It should be noted that the phase change material absorbs a large amount of heat when reaching the melting point, and maintains the main control module near the melting point through the phase change process, reducing temperature fluctuations. The specific type of the phase change material can be set according to actual needs, and no limitation is imposed thereon.

[0042] The heat storage module is used to store the phase change material. The specific type of the heat storage module can be set according to actual needs, and no limitation is imposed thereon. By way of example, the heat storage module can be a hollow shell structure with high heat conduction efficiency, and the phase change material is arranged inside the hollow shell structure. At the same time, the hollow shell respectively maintains a large contact area with the main control module and the air duct 4.

[0043] In some embodiments, the sub-station further includes: a thermoelectric power generation module, the thermoelectric power generation module is arranged on the housing 1, and the high-temperature side of the thermoelectric power generation module is close to the housing 1, and the low-temperature side of the thermoelectric power generation module is far from the housing 1.

[0044] It can be understood that since the high-temperature side of the thermoelectric power generation module is close to the housing 1, and the low-temperature side of the thermoelectric power generation module is far from the housing 1, the thermoelectric power generation module can generate electricity by using the temperature difference between the housing 1 and the roadway environment, which can not only effectively reduce the temperature of the housing 1, but also realize the supply of electric energy.

[0045] It should be noted that the thermoelectric power generation module is used to generate electricity by using the temperature difference between the high-temperature side and the low-temperature side, and can realize the self-generation and self-use of electric energy while cooling the sub-station, thereby reducing the energy consumption of the sub-station. By way of example, the electric energy generated by the thermoelectric power generation module can be applied to devices such as indicator lights in the sub-station.

[0046] In some embodiments, the sub-station further includes: a power supply module, the power supply module is arranged on the circuit board 3, and the power supply end of the power supply module extends outside the housing 1, and the power supply ends of the power supply module are respectively connected to the power supply end of the main control module and the power supply end of the communication module.

[0047] It can be understood that since the power supply end of the power supply module extends outside the housing 1, and the power supply ends of the power supply module are respectively connected to the power supply end of the main control module and the power supply end of the communication module, the power supply module can convert the electric energy transmitted by the external power supply and supply it to the main control module and the communication module, so as to ensure the stable operation of the main control module and the communication module while realizing integration.

[0048] It should be noted that the power supply module is used for the conversion of electric energy. The specific type of the power supply module can be set according to actual needs, and there is no limitation in this regard. By way of example, the power supply module may include a DC-DC buck circuit, a filtering circuit, etc., and directly supply power to each functional module.

[0049] In some embodiments, the sub-station further includes: a protection component, and the protection component includes: a filter screen and a driving mechanism. The filter screen is rotatably arranged at the air inlet end of the air duct 4, and the driving mechanism is in transmission connection with the filter screen. The driving mechanism is used to drive the filter screen to flip, so that the first side of the filter screen faces the air inlet end of the air duct 4, or the second side of the filter screen faces the air inlet end of the air duct 4.

[0050] It can be understood that since the filter screen is rotatably arranged at the air inlet end of the air duct 4 and the driving mechanism is in transmission connection with the filter screen, the filter screen can filter large-particle objects, and the driving mechanism can drive the filter screen to rotate. Moreover, when the driving mechanism drives the filter screen to flip so that the first side of the filter screen faces the air inlet end of the air duct 4, self-cleaning of the second side of the filter screen can be achieved while realizing the filtering function, and when the driving mechanism drives the filter screen to flip so that the second side of the filter screen faces the air inlet end of the air duct 4, self-cleaning of the first side of the filter screen can be achieved while realizing the filtering function. Thus, not only can the blockage problem of the air duct 4 be avoided, but also the cleaning and maintenance work of the filter screen can be omitted.

[0051] It should be noted that the filter screen is used to filter larger-particle objects to prevent large-particle objects from entering the air duct 4 and causing jamming and blockage problems. Small-particle objects can easily be discharged from the air duct 4 under the action of wind. Therefore, impurities, dust, etc. accumulated on the first side or the second side of the filter screen can be self-cleaned and there will be no blockage problem. The specific type of the filter screen can be set according to actual needs, and there is no limitation in this regard. By way of example, the filter screen can adopt an electrostatic adsorption filter screen.

[0052] The driving mechanism is used to drive the flipping of the filter screen to achieve self-cleaning of the relatively arranged first side or second side in the filter screen. The specific type of the driving mechanism can be set according to actual needs, and there is no limitation in this regard. By way of example, the driving mechanism can be a motor.

[0053] As Figure 2 and Figure 3 shown, in some embodiments, the shock-absorbing component 2 includes: a plurality of branch pipes 21 and a plurality of screws 24. The branch pipes 21 are arranged on the inner wall of the housing 1, and a plurality of elastic pieces 22 are arranged at intervals along the circumferential direction of the branch pipes 21 at the end of the branch pipes 21 away from the inner wall of the housing 1. The plurality of elastic pieces 22 form a shock-absorbing cylinder. Among them, the circuit board 3 is provided with a plurality of mounting holes, and the mounting holes are sleeved on the shock-absorbing cylinder. The threaded ends of the screws 24 are threadedly arranged in the shock-absorbing cylinder.

[0054] It can be understood that since a plurality of elastic pieces 22 are arranged at intervals along the circumferential direction of the end of the branch pipe 21 far from the inner wall of the housing 1, and the mounting holes of the circuit board 3 are sleeved on the shock-absorbing cylinder formed by the plurality of elastic pieces 22, and at the same time, the threaded end of the screw 24 is threadedly arranged in the shock-absorbing cylinder, the plurality of elastic pieces 22 can fix the circuit board 3 by using the radial clamping force generated when the screw 24 is screwed in. At the same time, by using the gaps formed by the spaced arrangement and their own elasticity, axial micro-deformation is allowed to absorb vibration energy, thereby realizing the shock absorption of the circuit board 3 and improving the underground service life of the substation.

[0055] It should be noted that the branch pipe 21 is used to support the circuit board 3. While the plurality of elastic pieces 22 thereon cooperate with the screw 24 to fix the circuit board 3, they can also realize the buffering and shock absorption of the circuit board 3. The specific type of the branch pipe 21 can be set according to actual needs, and no limitation is made thereto. By way of example, the branch pipe 21 can be a tubular structure. A plurality of notches are arranged at the end of the branch pipe 21 far from the inner wall of the housing 1, so as to form a plurality of elastic pieces 22. Threads adapted to the threaded portion of the screw 24 are provided on the inner side of the elastic pieces 22.

[0056] The screw 24 is used to fasten the circuit board 3. The specific type of the screw 24 can be set according to actual needs, and no limitation is made thereto. Among them, the head of the screw 24 can be located on the side of the circuit board 3 far from the branch pipe 21.

[0057] Such as Figure 2 and Figure 3 As shown in [figures], in some embodiments, a boss 23 is provided at the end of the branch pipe 21 far from the inner wall of the housing 1, and the head of the screw 24 and the boss 23 are located on both sides of the circuit board 3; the shock-absorbing assembly 2 further includes: a first rubber pad 25 and a second rubber pad 26. The first rubber pad 25 is arranged between the boss 23 and the circuit board 3, and the second rubber pad 26 is arranged between the head of the screw 24 and the circuit board 3.

[0058] It can be understood that since the first rubber pad 25 is arranged between the boss 23 and the circuit board 3, and the second rubber pad 26 is arranged between the head of the screw 24 and the circuit board 3, the circuit board 3 can realize shock absorption and buffering by using the first rubber pad 25 and the second rubber pad 26 between the boss 23 and the head of the screw 24, thereby further improving the shock-absorbing performance of the substation.

[0059] It should be noted that both the first rubber pad 25 and the second rubber pad 26 are made of rubber material, which can not only play a buffering role, but also provide damping force. The specific types of the first rubber pad 25 and the second rubber pad 26 can be set according to actual needs, and no limitation is made thereto.

[0060] In the sub-station of this embodiment, the elastic sheet 22 cooperates with the first rubber pad 25 and the second rubber pad 26 arranged up and down to achieve three-dimensional buffering, while balancing the clamping force and elasticity, and realizing the rapid and stable installation of the circuit board 3.

[0061] In some embodiments, the shock-absorbing assembly 2 further includes: a plurality of supports, which are arranged on the inner wall of the housing 1, and the supports are provided with buffer cavities, and a non-Newtonian fluid material is arranged in the buffer cavities, and one end of the branch pipe 21 away from the shock-absorbing cylinder is slidably arranged in the buffer cavity.

[0062] It can be understood that when high-frequency vibrations occur in the sub-station, the non-Newtonian fluid material hardens to absorb the impact, thereby further improving the shock-absorbing performance of the sub-station.

[0063] It should be noted that when high-frequency vibrations occur, the non-Newtonian fluid material hardens to absorb the impact, and when low-frequency vibrations occur, the elastic sheet 22 plays a role. Thus, the two cooperate to ensure the high shock-absorbing performance of the shock-absorbing assembly 2.

[0064] Among them, when the non-Newtonian fluid material is in low-frequency vibration, it can flow slowly. At the same time, a flow channel for the non-Newtonian fluid material to pass through is arranged at one end of the branch pipe 21 away from the shock-absorbing cylinder. That is to say, the non-Newtonian fluid material can flow between the rod chamber and the rodless chamber in the buffer cavity.

[0065] The sub-station of this embodiment is applicable to the measurement and management of the air volume of all mine ventilation systems. By adopting the collaborative design of single-board integration, air duct 4 heat dissipation, and shock-absorbing branch pipe 21, it realizes the trinity of "high integration - high efficiency heat dissipation - strong earthquake resistance" to improve the working ability of the underground sub-station, enabling the sub-station to monitor the environment and equipment status in the coal mine in real time, realizing the intelligent monitoring and control of the mine ventilation system, and meeting the different conditions of different mines and different roadways.

[0066] In the mine environment, due to the existence of a large number of electrical equipment and a complex electromagnetic environment, the equipment of the ventilation system is easily affected by various electromagnetic interferences, resulting in unstable or distorted signal transmission. However, the sub-station of this embodiment can significantly improve the stability and reliability of the signal transmission of the mine ventilation system, effectively suppress and eliminate these interferences, and ensure the accuracy and reliability of the signal transmission of the ventilation system. The sub-station of this embodiment plays an important role in promoting the intelligent construction of the mine ventilation system, helps to improve the stability, reliability and intelligent level of the mine ventilation system, and provides strong support for the safe production of the mine.
