Description

Technical Field

[0001] This utility model relates to the technical field of mine ventilation devices, specifically to an intelligent control device for a mine ventilation fan. Background Technology

[0002] As a core piece of equipment ensuring safe production in mines, mine ventilation fans rely on intelligent control systems that collect key data such as temperature, humidity, and methane concentration in real time through environmental monitoring components. This enables intelligent adjustment of the ventilation system, which is crucial for preventing methane explosions and ensuring miner safety. However, existing intelligent control devices for mine ventilation fans face numerous problems in the installation and operation of environmental monitoring equipment. On the one hand, traditional environmental monitoring equipment is often installed on the walls of mine roadways using simple fixing methods. Under the complex geological conditions of mines and the vibrations generated by equipment operation, long-term stable installation is difficult to guarantee, leading to loosening and displacement, resulting in distorted monitoring data and affecting the accuracy and effectiveness of intelligent ventilation fan control. On the other hand, the sensors inside the environmental monitoring equipment lack reliable anti-vibration measures, and frequent vibrations and impacts can easily damage sensor components.

[0026] Combined with appendix Figure 1 To be continued Figure 6An intelligent control device for a mine ventilation fan includes an environmental monitoring component and an explosion-proof control box 2. The environmental monitoring component is connected to the explosion-proof control box 2 via an armored cable 17. The environmental monitoring component consists of multiple mounting brackets evenly spaced along the sidewall of the main mine roadway. Each mounting bracket includes an L-shaped base 1, the vertical section of which is fixed to the roadway wall by bolts, and the horizontal section extends forward to form a cantilever structure. A sensor integration chamber 3 is fixedly installed at the upper end of the cantilever, and a temperature and humidity sensor 4 and a gas concentration sensor 5 are installed side by side inside the sensor integration chamber 3. The surface of the explosion-proof control box 1 is provided with a heat dissipation fin group 6, the bottom of the explosion-proof control box 1 is provided with an air inlet 8 with a filter screen 7, and the top is provided with a cooling fan 9. A shock-absorbing platform 10 is fixedly installed inside the sensor integration chamber 3, and the temperature and humidity sensor 4 and the gas concentration sensor 5 are both fixed on the shock-absorbing platform 10, with a metal isolation plate 11 between them.

[0027] The L-shaped base 1 has a reinforcing rib 12 below the horizontal section. The back of the L-shaped base 1 has a cable receiving cavity 16 for the armored cable 17 to pass through.

[0028] The shock absorption platform 10 includes a support plate 13 and spring dampers 14 fixed at the four corners of the bottom of the support plate 13. The bottom of the spring dampers 14 is fixed inside the sensor integration chamber 3. The sensor integration chamber 3 is hollowed out on all sides.

[0029] The working principle of this utility model is as follows: The intelligent control device for the mine ventilation fan collects environmental parameter data in real time from the temperature and humidity sensor 4 and the gas concentration sensor 5 in the environmental monitoring component. The data is transmitted to the explosion-proof control box 2 via the armored cable 17. The explosion-proof control box 2 analyzes and processes the data, and controls the operation of the mine ventilation fan according to the preset safety threshold, thereby realizing intelligent adjustment of the mine ventilation environment. At the same time, the structural design of each component ensures stable operation and efficient heat dissipation of the equipment in complex mine environments.

[0030] The working process of this utility model is as follows:

[0031] 1. Environmental Data Acquisition: L-shaped bases 1 are evenly spaced along the sidewalls of the main mine roadway, with their horizontal sections extending to form cantilever structures, fixing the sensor integration chamber 3 at a suitable location within the roadway. Temperature and humidity sensors 4 and gas concentration sensors 5 within the sensor integration chamber 3 monitor the temperature, humidity, and gas concentration data within the roadway in real time. The spring damper 14 and bearing plate 13 of the vibration damping platform 10 effectively buffer mine vibrations, reducing interference to the sensors; the metal isolation plate 11 prevents mutual interference between the two sensors, ensuring the accuracy of data acquisition.

[0032] 2. Data Transmission: The collected temperature, humidity, and gas concentration data are transmitted from the sensor integration compartment 3 to the explosion-proof control box 2 via armored cable 17. The armored cable 17 is installed in the cable receiving cavity 16 on the back of the L-shaped base 1 to prevent the cable from being damaged by external forces such as pulling and abrasion in the tunnel, thus ensuring the stability and reliability of data transmission.

[0033] 3. Data Processing and Command Issuance: After receiving the data, the explosion-proof control box 2 analyzes and processes it. When the monitored data exceeds the preset safety threshold, the explosion-proof control box 2 issues control commands according to the program settings to adjust the operating status of the mine ventilation fan, such as adjusting the fan speed, starting and stopping, etc., to improve the mine ventilation environment.

[0034] 4. Equipment heat dissipation ensures operation: During the operation of the device, the heat dissipation fins 6 on the surface of the explosion-proof control box 2 increase the heat dissipation area, the air inlet 8 with filter screen 7 at the bottom draws in cold air, and the cooling fan 9 at the top accelerates the airflow to expel heat from the box and maintain the normal operating temperature of the internal electronic components; the sensor integration compartment 3 is hollowed out in the front, back, left and right, which also facilitates the dissipation of internal heat and ensures the continuous and stable operation of the temperature and humidity sensor 4 and the gas concentration sensor 5.
