[0001] The present invention relates to the technical field of LED bracket lamps, in particular to a flameproof LED bracket lamp for mining. Background Art

[0002] The explosion-proof LED bracket lamp for mining is a lighting device designed specifically for gas and coal dust accumulation areas in coal mines. It provides high-intensity anti-interference lighting in high-risk scenarios. Its explosion-proof shell can effectively curb the propagation of internal electric sparks, creating a zero-blind-spot lighting environment for continuous underground operations. At the same time, it can effectively resist the impact of mining machinery, significantly improving the mine production safety factor and emergency rescue efficiency.

[0003] In actual use, in order to avoid lighting interruptions caused by power outages underground, mining bracket lights are equipped with backup power supplies. When the main power supply fails, the backup power supply is switched to ensure operation safety. Existing mining bracket lights mostly use manual switching of backup power supplies, which has obvious disadvantages. When the power is cut off underground, the dark environment makes it difficult for workers to operate, and manual switching of power supplies takes a long time, which brings great risks to operations and escape. Summary of the Invention

[0004] The purpose of the present invention is to provide a flameproof LED bracket lamp for mining, so as to solve the problem in the above-mentioned background technology that when manually switching the backup power supply of the existing flameproof LED bracket lamp for mining, the dark environment makes manual operation difficult, takes a long time, and brings risks to operation and escape.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a mining explosion-proof LED bracket lamp: comprising a shell, the upper surface of the shell is fixedly connected to a mesh cover, the surface of the shell is movably connected to a transparent part, the surface of the shell is bolted to a light source, the lower surface of the shell is fixedly connected to a junction box, the inner wall of the junction box is fixedly connected to a junction post, the side surface of the junction box is fixedly connected to an introduction device, one end of the junction box is bolted to a back cover, the bottom of the inner surface of the junction box is fixedly connected to a backup power supply, the inside of the backup power supply is rotatably connected to a power-on plate, the side of the backup power supply is fixedly connected to a first connecting post, the surface of the first connecting post is movably connected to a spring, the end of the spring away from the first connecting post is rotatably connected to a second connecting post, the bottom of the inner surface of the junction box is fixedly connected to a connecting seat, one side of the inner surface of the junction box is fixedly connected to an electromagnet, the lower surface of the electromagnet is fixedly connected to a slide rail, a slider is slidably connected to the surface of the slide rail, and the bottom of the inner surface of the junction box is fixedly connected to a damper.

[0006] Preferably, a sealing gasket is sandwiched between the shell and the surface of the transparent member.

[0007] Preferably, a copper pad is sandwiched between the housing and the light source.

[0008] Preferably, the interior of the junction box is hollow, and a partition is fixedly connected to a position inside the junction box near the rear cover, and the terminal penetrates and connects to the partition inside the junction box.

[0009] Preferably, a cable hole is provided in the center of the introduction device.

A first connecting column 11 is fixedly connected to the side of the backup power supply 9, and a spring 12 is movably connected to the surface of the first connecting column 11. The end of the spring 12 away from the first connecting column 11 is rotatably connected to the second connecting column 13. A connecting seat 14 is fixedly connected to the bottom of the inner surface of the junction box 5, and an electromagnet 15 is fixedly connected to one side of the inner surface of the junction box 5. The electromagnet 15 is connected to the main power supply of the device, and a slide rail 16 is fixedly connected to the lower surface of the electromagnet 15. A slider 17 is slidably connected to the surface of the slide rail 16, and an insulating rubber is fixedly connected to the lower surface of the slider 17. A damper 18 is fixedly connected to the bottom of the inner surface of the junction box 5. The above structures together achieve the effect of automatically switching the backup power supply 9 after the device is powered off. At the same time, the damper 18 plays a damping and shock-absorbing role to avoid damage to the device by impact. The insulating rubber of the slider 17 can also play a buffering role and prevent current from entering the slider 17.

[0026] Furthermore, a sealing gasket is sandwiched between the surface of the shell 1 and the transparent member 3. The sealing gasket is annular and has the same shape as the fitting surface of the shell 1 and the transparent member 3. The above structure keeps the device sealed to achieve explosion-proof effect.

[0027] Furthermore, a copper pad is sandwiched between the housing 1 and the light source 4. The above structure makes the device sealed to achieve explosion-proof effect.

[0028] Furthermore, the interior of the junction box 5 is hollow, and a partition is fixedly connected to the interior of the junction box 5 near the rear cover 8. The terminal 6 passes through the partition connected to the interior of the junction box 5. The above structure allows the cable to bring power into the interior of the junction box 5.

[0029] Furthermore, a cable hole is provided in the center of the introduction device 7, and a wire pressing plate is provided near the external top of the introduction device 7. The wire pressing plate is connected to the introduction device 7 by bolts. The above structure allows the cable to be connected to the inside of the device and connected to the terminal 6. The wire pressing plate can limit the cable to prevent the cable from shaking and falling off.

[0030] Furthermore, one end of the second connecting column 13 is fixedly connected to the side surface of the power-carrying plate 10 , the second connecting column 13 is connected to the spring 12 and the other end of the spring 12 is connected to the first connecting column 11 , so that the spring 12 can limit the rotation of the power-carrying plate 10 .

[0031] Furthermore, a connecting groove is provided inside the connecting seat 14, and the shape of the connecting groove corresponds to the shape of the top end of the power-carrying plate 10. The slider 17 is located directly above the power-carrying plate 10, and the damper 18 is located directly below the power-carrying plate 10. A support plate is provided on the top of the damper 18, and the horizontal height of the support plate is higher than the height of the accommodating groove of the connecting seat 14. The mass of the slider 17 is greater than the sum of the pulling force of the spring 12 on the power-carrying plate 10 and the supporting force of the damper 18 on the power-carrying plate 10. The above structure enables the slider 17 to slide downward and push the power-carrying plate 10 to fall into the inside of the connecting seat 14 after the electromagnet 15 loses power and loses its magnetic force. At the same time, the damper 18 plays a buffering and shock-absorbing role. The first connecting column 11, the spring 12 and the second connecting column 13 can make the power-carrying plate 10 rebound after losing the pressure of the slider 17, thereby disconnecting the backup power supply 9.

[0032] Working principle: The staff introduces the cable from the cable hole of the introduction device 7 to the connection terminal 6, fixes the device in the required position, and completes the installation. When the electromagnet 15 is connected to the main power supply of the device, an electromagnetic force is generated, and the magnetic force is greater than the mass of the slider 17. The slider 17 is adsorbed on the lower surface of the electromagnet 15. At this time, the end of the power-on plate 10 away from the backup power supply 9 tilts upward under the tension of the spring 12. The power-on plate 10 and the connection seat 14 are separated, and the backup power supply 9 is in a disconnected state. When the main power is disconnected, the electromagnet 15 loses its electromagnetic force, and the slider 17 slides downward along the slide rail 16 due to gravity. The power-on plate 10 is directly below the slider 17, and the mass of the slider 17 is greater than the sum of the tension of the spring 12 and the supporting force of the damper 18, so that the slider 17 can push the power-on plate 10 downward, and the end of the power-on plate 10 away from the backup power supply 9 enters the connection seat. 14, the power-on plate 10 can conduct electricity so that the backup power supply 9 is connected to the connecting seat 14, and the connecting seat 14 is connected to the light source 4, and then the backup power supply 9 is connected, so that the light source 4 resumes lighting. When the main power supply is repaired and connected again, the electromagnet 15 restores the electromagnetic force. The distance between the electromagnet 15 and the top of the slider 17 is less than the range of action of the electromagnetic force, so that the electromagnet 15 can adsorb the slider 17 again, and the damper 18 loses pressure and slowly rises. Under the pulling force of the spring 12 and the lifting action of the damper 18, the power-on plate 10 is separated from the connecting seat 14 and returns to its original position. The backup power supply 9 is disconnected, and the device is powered by the main power supply.
