Description
Technical Field
[0001] The present invention belongs to the technical field of lighting devices, and in particular relates to a lighting device with a protective structure for coal mine excavation. Background Art
[0002] At present, when mining underground in coal mines, tunnels are dug to provide mining, transportation, ventilation, drainage, power supply and other functions. In order to facilitate the mining work of miners, lighting devices are usually installed inside the coal mine tunnels. During the mining process, the lighting area generally moves with the progress of the tunnel. Lighting is a measure that uses various light sources to illuminate work and living places or individual objects. The use of artificial light sources is called "artificial lighting". The primary purpose of lighting is to create good visibility and a comfortable and pleasant environment.
[0003] Due to the high dust and humidity in coal mines, lighting lamps are easily covered by coal dust or become damp, resulting in reduced light transmittance, brightness attenuation, and even damage due to internal circuit shorts. Dust also adheres to the lamps, requiring them to be replaced entirely, increasing costs and affecting work efficiency. At the same time, minor collisions that may occur during operations, such as scratches from mine cars or accidental contact with construction tools, can easily damage the lamp body, shortening its service life. Existing lighting devices are mostly fixed installations and cannot adjust the illumination angle according to operational needs, resulting in a limited lighting range and being unsuitable for lighting at multiple angles or at a specific location within the mine. At the same time, some adjustable devices are complex to operate and require the use of tools, which is inefficient. Lighting equipment needs to be frequently moved to different work areas, but traditional devices are heavy and lack convenient mobile structures, making them difficult to transport. Manual handling is inefficient and poses safety risks. If the tunnel floor is uneven (such as tilted or uneven) during installation, the traditional support structure will not be able to maintain stable contact with the ground, and vibration or external force can easily cause the device to slide or tip over, affecting lighting stability.

[0013] Working principle or structural principle: multiple lighting lamps 2 are placed on the storage plate 701 for standby use, and tools for work can also be placed thereon. The staff holds the placement plate 1 and tilts the placement plate 1 so that the wheels 802 are in contact with the ground. At this time, the device can be pushed to move. When it is necessary to install the lighting lamp 2, the insert 306 is inserted into the through hole 305, and the baffle 307 is in contact with the inside of the first connecting seat 301. Then, the position of the socket 308 corresponds to the position of the fixing plate 309, and the bolt rod 310 is inserted through the socket 306. 08 is screwed into the fixing plate 309 to fix the lighting lamp 2 and the first connecting seat 301, and then the second connecting seat 302 is connected to the first connecting seat 301 through the external thread 303 and the internal thread 304. Then the position of the second connecting seat 302 corresponds to the position of the clamping plate 407, and the first handle 406 is manually turned to drive the bidirectional threaded rod 405 to rotate, so that the clamping plate 407 slides toward the middle in the limiting groove 404 to fix the second connecting seat 302, and the second handle 503 is turned to drive the adjusting threaded rod 502 to rotate. The gear 505 is moved to move, and the rack 504 is pushed to slide in the long slot 501. At this time, the rotating rod 402 can be rotated in the groove 401 under the action of the gear 505, thereby adjusting the up and down lighting angle of the lighting lamp 2. The left and right rotation of the placement plate 1 can adjust the left and right illumination angles. Pressing the pressing block 607 pushes the pressing plate 606 to slide inward on the fixed column 604. At this time, the spring 605 is compressed, and the insertion rod 608 is disengaged from the positioning hole 611, pushing the sliding plate 603 to drive the fixed plate 309 to move downward, so that the height of the placement plate 1 can be adjusted. At this time, the height of both sides can be adjusted at the same time to achieve the problem of adjusting the illumination height of the lighting lamp 2, or the height of one side can be adjusted separately. It is suitable for the inclined ground support inside the coal mine. At this time, the ground cone 610 is inserted into the ground to enhance stability during use. The second connecting seat 302 and the first connecting seat 301 protect the lighting lamp 2 to prevent dust in the coal mine from entering the lighting lamp 2. At the same time, the second connecting seat 302 is also prone to dust. It only needs to rotate the second connecting seat 302 to remove it for replacement.
