Description

Technical Field

[0001] The utility model belongs to the technical field of mine lighting, and in particular relates to underground lighting equipment in a coal mine. Background Art

[0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. Most of my country's coal mines are underground coal mines. Underground coal mines usually include tunnels, shafts, and mining faces, etc., and lighting equipment is installed at intervals in the tunnels to facilitate observation and work of staff.

[0003] In order to protect the lighting equipment from being damaged, a protective frame is often installed on the outside of the lighting lamp in the prior art to prevent the lighting lamp from being directly contacted with the outside world, thereby reducing the probability of the lighting lamp being damaged. However, there is a lot of dust and powder in the tunnels under the mine. After the lighting lamp has been used for a certain period of time, the outside of the bulb needs to be cleaned to prevent the luminous effect of the lighting lamp from being reduced. For example, China Utility Model Authorization Announcement No. CN215674897U discloses a mine lighting device that is easy to clean. When the lighting lamp needs to be cleaned after being used for a certain period of time, the staff rotates the protective frame, and multiple arc-shaped protective rods will simultaneously drive multiple drive connection blocks to rotate. The drive connection block will pull the rotating slider to move through the connecting rod. The movement of the rotating slider will drive multiple movable engaging teeth to move, so that the movable engaging teeth are no longer engaged with the fixed engaging teeth. At this time, the staff can remove the protective frame by pulling it downward, and then clean the lighting lamp.

[0004] Although the above-mentioned prior art can conveniently remove the arc-shaped protective rod for cleaning, the light bulb needs to be turned off during manual cleaning to avoid glare. After turning off the light bulb, the lighting equipment will not be visible in the mine. Utility Model Content

The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0029] like Figure 1-2 As shown, it is a schematic diagram of a coal mine underground lighting device and a lighting lampshade structure in a preferred embodiment of the utility model. The coal mine underground lighting device in this embodiment includes a fixed mounting plate 102 installed on the wall of the mine cave, and the outer wall of the fixed mounting plate 102 near the upper end is fixedly connected with an extension plate 103, and the end of the extension plate 103 is fixedly connected with a connecting ring 104, and the interior of the connecting ring 104 is detachably connected with a lighting lampshade 100, and the interior of the lighting lampshade 100 is installed with a lighting bulb 101 for emitting a light source. In this embodiment, the fixed mounting plate 102 is installed on the wall of the mine cave and connected to the lighting lampshade 100 through the connecting ring 104, so that the lighting lampshade 100 can be more stable while being convenient for installation and disassembly.

[0030] like Figure 2 as well as Figure 3As shown, it is a schematic diagram of the structure of the lighting lampshade and the arc-shaped protective cover in this embodiment. A second electric slide rail 106 is horizontally embedded near the bottom on the front side of the fixed mounting plate 102. The second electric slide rail 106 is internally slidably connected to the first sliding plate body 201. The end of the first sliding plate body 201 is detachably connected to the arc-shaped protective cover 200. In this embodiment, the arc-shaped protective cover 200 slides horizontally inside the second electric slide rail 106 through the first sliding plate body 201, so that it can be located below the lighting lampshade 100 when protecting the lighting bulb 101. When cleaning is required, it slides to one side through the second electric slide rail 106 to detach from the bottom of the lighting lampshade 100, so that the arc-shaped protective cover 200 can be easily cleaned while the lighting bulb 101 can be cleaned, so that the lighting bulb 101 can be kept clean during use to avoid affecting the brightness of the lighting bulb 101.

[0031] like Figure 4 As shown, it is a schematic diagram of the cleaning brush structure in this embodiment, a connecting rod 202 is fixedly connected to the outer wall of one side of the first sliding plate body 201, and the end of the connecting rod 202 is fixedly connected to an L-shaped connecting plate 203, the vertical side of the L-shaped connecting plate 203 is extended downward, and the end of the horizontal side is fixedly connected to a first assembly plate 204, and the bottom of the first assembly plate 204 is detachably connected to a driving motor 206, and the rotating end of the driving motor 206 passes through the first assembly plate 204 and is detachably connected to a cleaning brush 205. In this embodiment, since the cleaning brush 205 is connected to the arc-shaped protective cover 200 by the connecting rod 202 and the L-shaped connecting plate 203, the cleaning brush 205 moves to the bottom of the lighting bulb 101 and contacts it when the arc-shaped protective cover 200 moves to one side. At this time, the driving motor 206 is started to rotate to drive the cleaning brush 205 to rotate, so that the lighting bulb 101 can be cleaned, so that the lighting bulb 101 remains in a tidy state and the lighting effect is maintained.

[0032] It is worth noting that the cleaning brush 205 and the driving motor 206 are the first cleaning mechanism in this embodiment. The first cleaning mechanism includes but is not limited to the cleaning brush 205 and the driving motor 206. Any mechanism that can clean the lighting bulb 101 can be applied to this embodiment.

[0033] like Figure 2 5, which is a lighting lampshade and Figure 4The enlarged structural schematic diagram at point A in the middle shows that a vertical first electric slide rail 105 is embedded in the side of the lighting lampshade 100 away from the driving motor 206, and a second sliding plate 207 is slidably connected inside the first electric slide rail 105.

In this embodiment, the arc-shaped protective cover 200 moves to the bottom of the nozzle head 210, and the second sliding plate 207 is moved to one side by the first electric slide rail 105 so that the nozzle head 210 is inserted into the interior of the arc-shaped protective cover 200, and the micro air pump 209 pressurizes the external air and sprays it from the air outlet holes on the outer wall of the nozzle head 210, thereby causing the nozzle head 210 to rotate to purge the inner wall of the arc-shaped protective cover 200.

[0034] like Figure 5 As shown, in order to clean the outer wall of the arc-shaped protective cover 200, the outer wall of the nozzle head 210 near the upper end is fixedly connected with a connecting rod 211 in this embodiment, and the end of the connecting rod 211 is detachably connected with a semi-arc brush 212. The semi-arc brush 212 fits the outer wall of the arc-shaped protective cover 200 and cooperates with the rotation of the nozzle head 210 to clean the outer wall of the arc-shaped protective cover 200, so that the arc-shaped protective cover 200 can be automatically cleaned, saving labor and making cleaning more convenient. After cleaning, the arc-shaped protective cover 200 is reset to protect the lighting bulb 101.

[0035] It is worth noting that the above-mentioned micro air pump 209 and nozzle 210 are the second cleaning mechanism in this embodiment. The second cleaning mechanism includes but is not limited to the micro air pump 209 and nozzle 210.
