Description

Technical Field

[0001] The utility model relates to the technical field of gas monitoring, in particular to a coal uncovering area gas monitoring device capable of multi-angle monitoring. Background Art

[0002] Underground coal mining areas are the low-lying areas where gas disasters and accidents frequently occur. With the continuous strengthening of the intensity and depth of underground coal mining in recent years, high-risk accidents in mines have also continued to increase. At this time, it is necessary to monitor the gas concentration in the coal-excavating area in real time. For example, a gas monitoring device with a publication number of "CN213364688U" is used. During installation, the vertical connecting rod and the mine hole are fixed by a "J"-shaped buckle. The angle between the horizontal connecting rod and the vertical connecting rod is adjusted by a rotating mechanism to make the throat clamp in a suitable position. Finally, the shell and the throat clamp are fixed, so that the smoke sensor is fixed. During maintenance, the shell is removed to take the outer light out of the mine hole and then the internal electrical components are maintained. During operation, the fan rotates to suck the air in the mine hole from the long arc-shaped ventilation holes at the bottom of the outer light into the inner part of the outer light, and the air is fully contacted with the probe of the smoke sensor inside the outer light, and then discharged from the outer light through the gap between the cover and the fan blades, thereby ensuring the air circulation inside and outside the outer light and improving the detection accuracy.

[0003] When the above mechanism is in use, it detects the gas content in the air in the mine through the smoke sensor, transmits the detection signal to the main control unit, and then transmits it to the wireless network through the WiFi module, so that the staff can view the gas content in the mine in real time. However, the roof of the mine is uneven, so the air will flow through the monitoring equipment from different directions, and the detection direction of the above mechanism is fixed and cannot be adjusted, resulting in inaccurate detection of the gas content in the mine.

[0004] Therefore, we proposed a coal mining area gas monitoring equipment that can monitor from multiple angles to solve the above problems well. Utility Model Content

[0016] Compared with the prior art, the utility model has the following beneficial effects: the coal mining area gas monitoring equipment capable of multi-angle monitoring adopts a new structural design, and its specific contents are as follows:

[0017] (1) The first motor drives the connecting column to rotate, and the connecting column drives the shell to rotate. Then the second motor drives the fan to rotate through the shaft, so that the outside air can be sucked into the shell.

At the same time, the second motor drives the fan to rotate, and drives the rotating rod to rotate, so that the cleaning brush rotates and cleans the surface of the filter to prevent the filter from being blocked by dust and affecting the filtering effect.

[0021] Furthermore, when the movable plate drives the cleaning brush to rotate, the first magnet moves to the position of the second magnet. At this time, due to the principle of like-charged magnets repelling each other, the inclined rod rotates. At the same time, the lever principle is used to make the striking block at the other end of the inclined rod strike the side of the movable plate. When the first magnet is away from the second magnet, the inclined rod rotates and resets under the stored force of the vortex spring, so that the striking block strikes the movable plate back and forth, and then the vibration generated by the striking can be used to shake off the dust on the surface of the cleaning brush.

[0030] See also Figure 1-Figure 6 , the utility model provides the following technical solutions: a coal uncovering area gas monitoring device capable of multi-angle monitoring;

[0031] Embodiment 1: In order to solve the problem that the prior art cannot detect the air in the mine from multiple angles, resulting in insufficient accuracy in detecting the gas content in the mine, the following solution is disclosed.

[0033] When in use, the staff installs the device on the top of the mine cave through the mounting frame 2, and then starts the second motor. The second motor drives the shaft 6 to rotate, so that the shaft 6 drives the fan to rotate, and the air in the mine cave is sucked into the shell 1 from the air inlet. At this time, the gas content in the air sucked into the shell 1 is detected by the gas monitoring probe 4. Once the gas content in the air is too high, the gas monitoring probe 4 will transmit the signal to the processing module, and start the sound and light alarm 7 through the processing module to sound an alarm to remind the workers in the mine. After the detection is completed, the air in the shell 1 is discharged from the exhaust port, and then the first motor is started. The first motor drives the connecting column 8 to rotate, so that the connecting column 8 and the shell 1 rotate, and the slider 9 will slide in the slide groove 10, which can improve the stability of the rotation of the shell 1, and then allow the air from different directions in the mine cave to be sucked into the shell 1, thereby realizing multi-angle detection and improving the accuracy of detection.

[0034] Embodiment 2: Different from Embodiment 1, this embodiment can filter the dust in the air through the filter 5 to prevent the dust from affecting the detection effect of the gas monitoring probe 4.

[0036] Embodiment 3: Different from Embodiment 2, this embodiment uses the inclined rod 15 to drive the striking block 17 to strike the side of the movable plate 12 back and forth, which can shake off the dust on the surface of the cleaning brush 19 and improve the subsequent cleaning effect of the cleaning brush 19. For details, refer to Figure 1 and Figure 4-Figure 6As shown, a fixing plate 14 is fixed to the left side of the bottom of the inner wall of the housing 1, and an inclined rod 15 is hinged on the upper right side of the fixing plate 14, and a second magnet 16 is installed on the side of one end of the inclined rod 15, the second magnet 16 corresponds to the position of the first magnet 13, and the second magnet 16 has the same magnetic pole as the opposite surface of the first magnet 13, and a striking block 17 is fixed to the side of the other end of the inclined rod 15, and a vortex spring 18 is installed at the connection position between the shaft end in the middle of the inclined rod 15 and the fixing plate 14;

[0037] When the movable plate 12 drives the cleaning brush 19 to rotate, the first magnet 13 moves to the position of the second magnet 16. At this time, due to the principle of like-charged magnets repelling each other, the inclined rod 15 rotates, and due to the principle of lever, the striking block 17 at the other end of the inclined rod 15 strikes the side of the movable plate 12. When the movable plate 12 drives the first magnet 13 away from the second magnet 16, the inclined rod 15 rotates and resets under the stored force of the vortex spring 18, and the above operation is repeated, so that the striking block 17 strikes the movable plate 12 reciprocatingly, and then the vibration generated during the striking can be used to shake off the dust on the surface of the cleaning brush 19.
