Description

Technical Field

[0001] This utility model relates to the field of mining lighting, and in particular to an energy-saving explosion-proof mining lighting. Background Technology

[0002] Mining lights are lighting equipment specifically designed for special environments such as mines. They are mainly used for lighting in underground places such as mines and tunnels. Their main purpose is to ensure the safety of miners and meet the lighting needs of mine operations.

[0003] Existing mining lighting fixtures all use LED lamps. Compared with traditional incandescent and fluorescent lamps, LED lamps have higher energy efficiency, longer service life, and less heat generation. Choosing suitable LED mining lighting fixtures can significantly reduce energy consumption and achieve energy-saving effects. Due to the presence of flammable and explosive substances such as gas and dust in the mining environment, the safety performance of mining lighting fixtures, as critical lighting equipment, is of paramount importance. Currently, when the main body of mining lighting fixtures is exposed to external explosive impacts, the impact force often acts directly on the lamp body, causing damage and safety accidents. At the same time, when the internal LED chips malfunction and may explode, traditional protective structures cannot release internal pressure in time, making it difficult to achieve reliable internal explosion isolation, posing significant safety hazards to mine production. Utility Model Content

[0004] The technical problem this utility model aims to solve is as follows: Due to the presence of flammable and explosive substances such as gas and dust in the mine environment, the safety performance of mine lighting lamps, as key lighting equipment, is of paramount importance. Currently, when the main body of a mine lighting lamp is exposed to external explosive impact, it is often damaged and causes safety accidents because the external explosive impact acts directly on the lamp body. At the same time, when the lamp beads inside the lamp malfunction and may explode, the traditional protective structure cannot release the internal pressure in time, making it difficult to achieve reliable internal explosion isolation, which brings significant safety hazards to mine production.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an energy-saving explosion-proof mining lighting lamp, including a mining lighting lamp body, an inner wall of which is provided with a strip of lamp beads, a mesh cover on one side of the mining lighting lamp body, and a protective device on one side of the mining lighting lamp body. The protective device can achieve the effect of enhancing the protective cover's protection against external explosive impact by installing a corrugated sealing strip and a first spring between the protective cover and the abutment frame for buffer sealing treatment. At the same time, a pressure relief mechanism is installed on the protective cover to relieve pressure when the strip of lamp beads explodes, avoiding safety hazards caused by the explosion of the protective cover.

[0006] Preferably, the protective device includes two abutment frames, one side of which is fixedly installed on the outer surface of the main body of the mining lighting lamp; a protective cover, wherein a plurality of fitting mechanisms are provided between the inner wall of the protective cover and the mesh cover, and the inner wall of the protective cover is fitted onto the outer surface of the main body of the mining lighting lamp; two corrugated sealing strips, one side of which is fixedly installed on one side of the protective cover; two abutment plates, one side of which is fixedly installed on one side of the corrugated sealing strip and abuts against one side of the abutment frame; a plurality of first springs, wherein the two ends of the first springs are respectively fixedly installed on one side of the abutment plate and one side of the protective cover; and a plurality of pressure relief mechanisms, wherein the pressure relief mechanisms are disposed in the inner wall of the protective cover for discharging suddenly increased pressure inside the protective cover, thereby achieving the effect of explosion-proof protection for the interior of the main body of the mining lighting lamp.

[0007] The aforementioned components achieve the following effect: By incorporating a protective device, the mining lighting lamp, with LEDs and other electric light sources as its core, releases light energy through the recombination of electrons and holes in the semiconductor PN junction, or heats the filament with current, or excites phosphors to emit light through gas discharge. Before installing the main body of the mining lighting lamp in the mine, a protective cover can be fitted onto the outer surface of one end of the main body, with the abutment plates on both sides abutting against one side of the abutment frame on the main body. Then, pressing it forcefully against one side of the abutment frame causes the corrugated sealing strip and the first spring to contract, causing the installation mechanism on the inner wall of the protective cover to engage with the mesh cover. This allows the protective cover to be quickly and securely installed on the main body of the mining lighting lamp. Once installed, the first spring and the corrugated sealing strip will move the protective cover... The repositioning mechanism creates an elastic buffer space between the two ends of the protective cover and the two abutment frames. In the event of an explosion in the mine, this space is compressed to buffer the impact force and seal the gaps, further enhancing the explosion-proof protection effect. This effectively protects the main body of the mine lighting lamp from malfunction and ensures stable operation in hazardous environments. It balances ease of installation with reliable explosion-proof protection, providing a solid guarantee for its safe and energy-efficient operation under complex mine conditions. Furthermore, if the lamp beads inside the main body of the mine lighting lamp malfunction and explode, the pressure relief mechanism installed on the protective cover will release the suddenly increased internal pressure, achieving an internal explosion-proof effect and reducing safety hazards during the use of the main body of the mine lighting lamp.

[0008] Preferably, the protective device further includes two protective shells, wherein one side of the protective shell is fixedly installed on one side of the protective cover, and the inner wall is sleeved on the outer surface of the abutment frame, and one side of the abutment plate is slidably connected to the inner wall of the protective shell.

[0009] The effect achieved by the above components is as follows: by setting up a protective shell, after the protective cover is installed, several first springs can be placed between the inner wall of the protective shell and one side of the abutment plate and the corrugated sealing strip, so that it is not easily exposed to the outside, and to prevent impurities in the air from falling into the gaps and causing jamming.

[0010] Preferably, the pressure relief mechanism includes a bracket, and the inner wall of the protective cover is symmetrically provided with circular holes, wherein the two ends of the bracket are respectively fixedly installed in the inner wall of the circular holes; a third spring, wherein one end of the third spring is fixedly installed on one side of the bracket; and a piston block, wherein one side of the piston block is fixedly installed on one side of the third spring, and the outer surface dimension is larger than the inner wall of the circular holes.

[0011] The effect achieved by the above-mentioned components is as follows: by setting up a pressure relief mechanism, when the lamp beads inside the main body of the mining lighting lamp explode due to a malfunction, the pressure inside the protective cover will suddenly increase. The increased pressure will enter the round hole and push the piston block outward, releasing the seal on the round hole. This will cause the third spring to stretch between the piston block and the bracket, at which point the pressure will be discharged from the round hole, achieving the effect of pressure relief and explosion prevention, and reducing the safety hazards when the main body of the mining lighting lamp is in use.

[0012] Preferably, the casual clothing mechanism includes an elastic groove block, wherein the inner wall of the elastic groove block is fitted onto the outer surface of the mesh cover; and a second spring, wherein the two ends of the second spring are respectively fixedly installed on one side of the elastic groove block and one side of the inner wall of the protective cover.

[0013] The effect achieved by the above-mentioned components is as follows: By setting up a convenient installation mechanism, before the main body of the mining lighting lamp is installed in the mine for use, the protective cover can be fitted onto the outer surface of one end of the main body of the mining lighting lamp, so that the abutment plates on both sides abut against one side of the abutment frame on the main body of the mining lighting lamp, and the opening of the elastic groove block will align with the mesh rod on the mesh cover. Then, by pressing the protective cover forcefully against one side of the abutment frame, the second spring will be squeezed and contracted. After the second spring is fully contracted, it will push the elastic groove block to undergo elastic deformation and then return to the mesh rod fitted onto the mesh cover. Therefore, the protective cover can be quickly installed and fixed on the main body of the mining lighting lamp, improving the ease of installation of the protective cover.

[0014] Preferably, the casual clothing mechanism further includes a telescopic rod, wherein the outer surface of the telescopic rod penetrates the inner wall of the second spring and its two ends are respectively fixedly installed on one side of the elastic groove block and one side of the inner wall of the protective cover.

[0015] The effects achieved by the above components are as follows: by setting the telescopic rod, the connection area between the elastic groove block and the inner wall of the protective cover can be increased, while the movement direction of the elastic groove block is limited, and the inner wall of the second spring is supported and reinforced, making it easier to install the elastic groove block, improving the installation effect and service life.

[0016] Preferably, limit blocks are fixedly installed at both ends of the elastic groove block, wherein the two limit blocks are fixed at an angle on both sides of the entrance of the elastic groove block.

[0017] The effect achieved by the above components is that by setting the limiting block, the area at the entrance of the elastic groove block can be increased, making it easier to quickly align with the outer surface of the mesh cover and snap it on during installation.

[0018] Preferably, a plurality of anti-slip strips are fixedly installed on the inner wall of the elastic groove block, and the anti-slip strips are made of rubber.

[0019] The effect achieved by the above components is that by setting anti-slip strips, the contact friction of the inner wall of the elastic groove block can be increased, making it more secure when it is fitted onto the mesh cover for fixation.

[0020] The beneficial effects of this utility model are:

[0021] By incorporating protective devices, mining lights utilize LEDs and other electric light sources as their core. They emit light through the recombination of electrons and holes in semiconductor PN junctions, releasing light energy or heating the filament with current, or exciting phosphors through gas discharge. Before installing the main body of the mining light in the mine, a protective cover can be fitted over one end of the main body, with its two side abutting plates abutting against one side of the abutting frame on the main body. Pressing it firmly against one side of the abutting frame causes the corrugated sealing strip and the first spring to contract, locking the mounting mechanism on the inner wall of the protective cover onto the mesh cover. This allows for quick and easy installation and fixation of the protective cover onto the main body of the mining light. Once installed, the first spring and the corrugated sealing strip will move the protective cover... The repositioning mechanism creates an elastic buffer space between the two ends of the protective cover and the two abutment frames. In the event of an explosion in the mine, this space is compressed to buffer the impact force and seal the gaps, further enhancing the explosion-proof protection effect. This effectively protects the main body of the mine lighting lamp from malfunction and ensures stable operation in hazardous environments. It balances ease of installation with reliable explosion-proof protection, providing a solid guarantee for its safe and energy-efficient operation under complex mine conditions. Furthermore, if the lamp beads inside the main body of the mine lighting lamp malfunction and explode, the pressure relief mechanism installed on the protective cover will release the suddenly increased internal pressure, achieving an internal explosion-proof effect and reducing safety hazards during the use of the main body of the mine lighting lamp.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Figure 1-7 The energy-saving explosion-proof mining lighting lamp shown includes a main body 1, an inner wall of which is provided with a strip of lamp beads 3, a mesh cover 4 on one side of the main body 1, and a protective device 2 on one side of the main body 1. The protective device 2 can achieve the effect of enhancing the protection of the protective cover 22 against external explosive impact by installing a corrugated sealing strip 23 and a first spring 25 between the protective cover 22 and the abutment frame 21 for buffer sealing treatment. At the same time, a pressure relief mechanism 28 is installed on the protective cover 22 to relieve pressure when the strip of lamp beads 3 explodes, so as to avoid safety hazards caused by the explosion of the protective cover 22.

[0034] Figure 1-7The protective device 2 shown includes two abutment frames 21, one side of which is fixedly installed on the outer surface of the main body 1 of the mining lighting lamp; a protective cover 22, with several portable mechanisms 27 provided between the inner wall of the protective cover 22 and the mesh cover 4, the inner wall of the protective cover 22 being fitted onto the outer surface of the main body 1 of the mining lighting lamp; two corrugated sealing strips 23, one side of which is fixedly installed on one side of the protective cover 22; two abutment plates 24, one side of which is fixedly installed on one side of the corrugated sealing strips 23, and one side abuts against one side of the abutment frame 21; several first springs 25, the two ends of which are respectively fixedly installed on one side of the abutment plate 24 and one side of the protective cover 22; and several pressure relief mechanisms 28, which are provided in the inner wall of the protective cover 22 to discharge the pressure that suddenly increases inside the protective cover 22, thereby achieving the effect of explosion-proof protection for the inside of the main body 1 of the mining lighting lamp. By setting up the protective device 2, the mining lighting lamp uses LED and other electric light sources as its core. It releases light energy through the recombination of electrons and holes in the semiconductor PN junction, or uses current to heat the filament or excites phosphors to emit light through gas discharge. Before installing the main body 1 of the mining lighting lamp in the mine, the protective cover 22 can be fitted onto the outer surface of one end of the main body 1, so that the abutment plates 24 on both sides abut against one side of the abutment frame 21 on the main body 1. Then, it is pressed forcefully against one side of the abutment frame 21, causing the corrugated sealing strip 23 and the first spring 25 to contract, causing the installation mechanism 27 on the inner wall of the protective cover 22 to lock onto the mesh cover 4. This allows the protective cover 22 to be quickly installed and fixed onto the main body 1 of the mining lighting lamp. After installation, the first spring 25 and the corrugated sealing strip 23... 3 will cause the protective cover 22 to reset, forming an elastic buffer space between the two ends of the protective cover 22 and the two abutment frames 21. In the event of an explosion in the mine, this buffers the impact force and seals the gaps, further enhancing the explosion-proof protection effect and effectively protecting the main body 1 of the mine lighting lamp in a hazardous environment. It balances the ease of installation with the reliability of explosion-proof protection, providing a solid guarantee for its safe and energy-saving operation under complex mine conditions. At the same time, if the lamp bead strip 3 inside the main body 1 of the mine lighting lamp malfunctions and explodes, the pressure relief mechanism 28 installed on the protective cover 22 will release the suddenly increased internal pressure, achieving the effect of internal explosion protection and reducing the safety hazards when using the main body 1 of the mine lighting lamp. The protective device 2 also includes two protective shells 26. One side of the protective shell 26 is fixedly installed on one side of the protective cover 22, and its inner wall is fitted onto the outer surface of the abutment frame 21. One side of the abutment plate 24 is slidably connected to the inner wall of the protective shell 26. By setting up the protective shell 26, after the protective cover 22 is installed, several first springs 25 can be placed between the inner wall of the protective shell 26 and one side of the abutment plate 24 and the corrugated sealing strip 23, so that it is not easily exposed to the outside, and to prevent impurities in the air from falling into the gap and causing jamming.

[0035] Figure 1-7 The pressure relief mechanism 28 shown includes a bracket 282, and symmetrical circular holes 281 are provided on the inner wall of the protective cover 22. Both ends of the bracket 282 are fixedly installed in the inner wall of the circular holes 281. A third spring 283 is fixedly installed on one side of the bracket 282. A piston block 284 is fixedly installed on one side of the third spring 283, and its outer surface dimension is larger than the inner wall of the circular holes 281. By setting up the pressure relief mechanism 28, when the lamp bead strip 3 inside the mine lighting lamp body 1 explodes due to a malfunction, the pressure inside the protective cover 22 will suddenly increase. The increased pressure will enter the circular holes 281, pushing the piston block 284 outward, releasing the seal on the circular holes 281. This causes the third spring 283 to stretch between the piston block 284 and the bracket 282, at which point the pressure will be discharged from the circular holes 281, achieving the effect of pressure relief and explosion prevention, and reducing safety hazards during the use of the mine lighting lamp body 1.

[0036] Figure 1-7 The casual clothing mechanism 27 shown includes an elastic groove block 272, wherein the inner wall of the elastic groove block 272 is fitted onto the outer surface of the mesh cover 4; and a second spring 271, wherein the two ends of the second spring 271 are respectively fixedly installed on one side of the elastic groove block 272 and one side of the inner wall of the protective cover 22. By setting up the portable mechanism 27, before the main body 1 of the mining lighting lamp is installed in the mine for use, the protective cover 22 can be fitted onto the outer surface of one end of the main body 1 of the mining lighting lamp, so that the abutment plates 24 on both sides abut against one side of the abutment frame 21 on the main body 1 of the mining lighting lamp, and the opening of the elastic groove block 272 will be aligned with the net rod on the mesh cover 4. Then, the protective cover 22 is pressed forcefully against one side of the abutment frame 21, which will compress the second spring 271 and cause it to contract. After the second spring 271 is fully contracted, it will push the elastic groove block 272 to undergo elastic deformation and then return to the net rod fitted onto the mesh cover 4. Therefore, the protective cover 22 can be quickly installed and fixed on the main body 1 of the mining lighting lamp, improving the ease of installation of the protective cover 22.

[0037] Figure 1-7The illustrated casual clothing mechanism 27 also includes a telescopic rod 275, the outer surface of which penetrates the inner wall of the second spring 271, with both ends fixedly installed on one side of the elastic groove block 272 and the inner wall of the protective cover 22, respectively. By setting the telescopic rod 275, the connection area between the elastic groove block 272 and the inner wall of the protective cover 22 can be increased, while limiting the movement direction of the elastic groove block 272 and supporting and reinforcing the inner wall of the second spring 271, making it easier to install the elastic groove block 272 and improving the installation effect and service life. Limiting blocks 273 are fixedly installed at both ends of the elastic groove block 272, with two limiting blocks 273 fixed at an angle on both sides of the entrance of the elastic groove block 272. By setting the limiting blocks 273, the area at the entrance of the elastic groove block 272 can be increased, facilitating quick alignment and locking onto the outer surface of the mesh cover 4 during installation. Several anti-slip strips 274, made of rubber, are fixedly installed on the inner wall of the elastic groove block 272. By setting anti-slip strips 274, the contact friction of the inner wall of the elastic groove block 272 can be increased, making it more secure when it is fixed on the mesh cover 4.

[0038] Working Principle: The mining lighting lamp uses LEDs and other electric light sources as its core. It releases light energy through the recombination of electrons and holes in the semiconductor PN junction, or uses current to heat the filament or excites phosphors to emit light through gas discharge. Before installing the main body 1 of the mining lighting lamp in the mine, the protective cover 22 can be fitted onto the outer surface of one end of the main body 1, with the abutment plates 24 on both sides abutting against one side of the abutment frame 21 on the main body 1. The opening of the elastic groove block 272 will align with the mesh rod on the mesh cover 4. Pressing the protective cover 22 forcefully against one side of the abutment frame 21 will compress the second spring 271, causing it to contract. After the second spring 271 is fully contracted, it will push the elastic groove block 272 to elastically deform and return to its original position on the mesh rod on the mesh cover 4. Therefore, the protective cover 22 is quickly installed and fixed onto the main body 1 of the mining lighting lamp. After installation, the first spring 25 and the corrugated sealing strip 23 will cause the protective cover 22 to return to its original position. This design creates an elastic buffer space between the two ends of the protective cover 22 and the two abutment frames 21. In the event of an explosion in the mine, this space is compressed to buffer the impact and seal the gaps, further enhancing the explosion-proof protection effect. This effectively protects the main body 1 of the mine lighting lamp from malfunction and ensures stable operation in hazardous environments. It also balances ease of installation with reliable explosion-proof protection, providing a solid guarantee for its safe and energy-efficient operation under complex mine conditions. Furthermore, if the lamp bead strip 3 inside the main body 1 of the mine lighting lamp malfunctions and explodes, the pressure inside the protective cover 22 will suddenly increase. The increased pressure will enter the round hole 281 and push the piston block 284 outward, releasing the seal on the round hole 281. This will cause the third spring 283 to stretch between the piston block 284 and the bracket 282, at which point the pressure will be discharged from the round hole 281, achieving the effect of pressure relief and explosion prevention, and reducing the safety hazards when using the main body 1 of the mine lighting lamp.
