Description

Technical Field

[0001] The utility model relates to the technical field of underground mine inspection, and in particular to an underground mine unmanned aerial vehicle inspection device. Background Art

[0002] Mining is a complex process involving multiple aspects. Open-pit mining involves directly extracting useful minerals from the exposed surface. First, surface vegetation, soil, and overburden must be removed to expose the ore. Large excavators are then used to excavate the ore and transported to a beneficiation plant or smelter via conveyor equipment. While relatively low mining costs, high ore recovery rates, high production efficiency, and favorable operating conditions are associated with significant environmental damage, the use of a large area of ​​land, and significant climatic influences. Underground mining involves entering the ground through tunnels and tunnels to extract buried ore. This requires the construction of tunnels and tunnels, including vertical shafts, inclined shafts, and roadways. The ore is then extracted using mining methods and brought to the surface using hoists. This method minimizes damage to the surface environment and is suitable for mining deeper or higher-grade ores. However, mining costs are high, production efficiency is relatively low, operational safety is poor, and ventilation and drainage systems are complex.

[0003] During underground mining, regular inspections of the underground environment and equipment are important for ensuring safe production. Traditional manual inspection methods have many drawbacks. The underground environment is complex, with problems such as gas, dust, humidity, and narrow space. When workers go down to the mine for inspection, there are great safety hazards. Therefore, an underground drone inspection device is proposed. Utility Model Content

[0022] The present invention is further described in detail below with reference to the embodiments:

[0023] Example 1

[0024] like Figure 1-5 As shown, the utility model provides an underground drone inspection device, including an underground cruising mechanism, the bottom of the cruising mechanism is fixedly connected to an underground detection mechanism, the underground detection mechanism includes an installation box 21, the inner wall of the installation box 21 is fixedly connected to a circuit board 22 with a central control module installed, one end of the surface of the circuit board 22 is fixedly connected to an infrared absorption sensor 23 for detecting the gas concentration under the mine, the middle of the surface of the circuit board 22 is fixedly connected to an electrochemical sensor 24 for detecting the carbon dioxide concentration under the mine, and the other end of the surface of the circuit board 22 is fixedly connected to an electrochemical oxygen sensor 25 for detecting the oxygen content concentration under the mine.

[0025] In this embodiment, during the flight, the second motor 28 drives the fan blades 29 to rotate, so that the air under the mine is filtered through the multi-layer filter plate 210 and then comes into contact with the infrared absorption sensor 22, the electrochemical sensor 24 and the electrochemical oxygen sensor 25 to detect the gas, carbon monoxide and oxygen content under the mine.

[0026] Example 2

[0027] like Figure 1-5As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the bottom of the cruise mechanism is fixedly connected to an underground mine detection mechanism, and the underground mine detection mechanism includes a mounting box 21, and the inner wall of the mounting box 21 is fixedly connected to a circuit board 22 on which a central control module is installed, one end of the surface of the circuit board 22 is fixedly connected to an infrared absorption sensor 23 for detecting the gas concentration under the mine, and the middle part of the surface of the circuit board 22 is fixedly connected to an electrochemical sensor 24 for detecting the carbon oxide concentration under the mine, and the other end of the surface of the circuit board 22 is fixedly connected to an electrochemical oxygen sensor 25 for detecting the oxygen content concentration under the mine, one end of the mounting box 21 is plugged into a container box 26, and the inner wall of the container box 26 is fixedly connected to a mounting plate 27, one side of the mounting plate 27 is fixedly connected to a second motor 28, one end of the rotating shaft of the second motor 28 is fixedly connected to a fan blade 29, one end of the inner cavity of the container box 26 is fixedly connected to a filter plate 210, one side of the mounting box 21 is fixedly connected to a packaging frame 211, and the other end of the mounting box 21 is provided with a dustproof plate 212.

[0028] In this embodiment, the multi-layer filter plate 210 at the air inlet reduces dust from the air in the mine and falls onto the surface of the circuit board 22, making it easier to use. Furthermore, the container allows the filter plate 210, the second motor 28, and the fan blades 29 to be removed all at once after the packaging frame 211 is removed, making dust cleaning easier. Compared to conventional manual underground mine inspections, this inspection is both safer and more efficient.

[0029] Example 3

[0030] like Figure 1-5 As shown, on the basis of embodiment 1, the utility model provides a technical solution: preferably, the bottom of the cruise mechanism is fixedly connected with an underground detection mechanism, the underground detection mechanism includes an installation box 21, the inner wall of the installation box 21 is fixedly connected with a circuit board 22 installed with a central control module, one end of the surface of the circuit board 22 is fixedly connected with an infrared absorption sensor 23 for detecting the gas concentration under the mine, the middle of the surface of the circuit board 22 is fixedly connected with an electrochemical sensor 24 for detecting the carbon dioxide concentration under the mine, and the other end of the surface of the circuit board 22 is fixedly connected with an electrochemical sensor for detecting the oxygen content concentration under the mine. The oxygen sensor 25 is provided, and the underground cruising mechanism includes a power supply unit 11 with a lighting lamp at one end. The surface of the power supply unit 11 is fixedly connected with a connecting rod 12, and the bottom of the power supply unit 11 is fixedly connected to the top of the mounting box 21. One end of the connecting rod 12 is fixedly connected with a mounting frame 13, and the interior of the mounting frame 13 is fixedly connected with a first motor 14.

[0031] In this embodiment, when inspecting underground mines, the cruising mechanism operates in the same way as a conventional drone. The worker controls it through a handle and transmits the control signal to the central control module in the circuit board 21. The first motor 14 of the central control module drives the flight blades 15 to rotate, thereby enabling the device to cruise underground. The central control module uses STM32F427, which has a high processing speed and rich peripheral interfaces, and can efficiently process flight control algorithms, sensor data, etc.

[0032] Let’s talk about the working principle of the drone inspection device under the mine in detail.

Operated by a worker using a handle, the control signal is transmitted to the central control module within the circuit board 21. The central control module's first motor 14 drives the flight blades 15 to rotate, enabling the device to cruise underground. During flight, the second motor 28 drives the blades 29 to rotate, allowing the air below to pass through the multi-layer filter plate 210 and then contact the infrared absorption sensor 22, electrochemical sensor 24, and electrochemical oxygen sensor 25 to detect the gas, carbon monoxide, and oxygen levels below the mine.

The container allows the filter plate 210, second motor 28, and blades 29 to be removed once the packaging frame 211 is removed, making dust cleaning easier. Compared to conventional manual underground mine inspections, the inspection is both safer and more efficient.

[0034] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
