Description

Technical Field

[0001] This utility model relates to the field of mining lighting technology, and in particular to an anti-glare explosion-proof LED lighting fixture for mining. Background Technology

[0002] Anti-glare explosion-proof LED mining lamps are special lighting tools designed for explosive hazardous environments such as coal mines and oil and gas fields. They employ an explosion-proof structure, using a robust metal shell and precision-machined joints to ensure that even in the event of an internal explosion, external flammable gases will not ignite. Furthermore, special optical design or surface treatment effectively suppresses the glare effect caused by strong light reflection, ensuring sufficient illumination of the work area while avoiding direct light irritation to the eyes.

[0003] The patent with publication number CN203517630U mentions an anti-glare explosion-proof LED lamp for mining. Based on existing explosion-proof LED lamps for mining, it adds a secondary diffusion material layer inside the explosion-proof glass cover of the LED lamp. The anti-glare explosion-proof LED lamp is circular, including a main body with a top cover and a hanging ring. An LED light source board is located below the main body, with LED beads on the board. The explosion-proof glass cover is located below the LED beads. The diffusion material layer is installed as far away from the LED beads as possible, and its shape depends on the shape of the glass cover. The principle is to adhere as closely as possible to the inner wall of the glass cover. Adding this material alters the light propagation path of the LED beads, making them invisible to the eye and avoiding glare.

[0004] The inventors have discovered at least the following problems in the prior art:

[0005] Existing anti-glare explosion-proof LED mining lamps typically achieve explosion protection through their high-strength LED lamp housings. However, with increased use and maintenance, and frequent replacement of the internal LED lamp boards, the performance of their explosion-proof mechanism will decline.

[0006] In addition, when an LED fails and explodes, the resulting flames will bake the anti-glare lampshade, thus accelerating its aging.

[0007] Therefore, this solution provides an anti-glare explosion-proof LED lighting fixture for mining to address the aforementioned problems. Utility Model Content

[0008] The purpose of this utility model is to provide an anti-glare explosion-proof LED lamp for mining, in order to solve the problems in the prior art where the performance of the explosion-proof lamp housing deteriorates after long-term use and the flame accelerates the aging of the anti-glare lamp cover in case of failure.

[0009] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0010] An anti-glare explosion-proof LED lamp for mining includes an outer explosion-proof mechanism, an inner lamp body mechanism, and an inner buffer mechanism and a flame guiding mechanism. The outer explosion-proof mechanism includes an outer protective shell and a heat dissipation mounting box installed inside the outer protective shell. The lamp body mechanism includes an inner explosion-proof lamp shell and a lamp body installed inside the inner explosion-proof lamp shell. The inner explosion-proof lamp shell is bolted to the inner side of the heat dissipation mounting box. The buffer mechanism is located on the periphery of the lamp body. The buffer mechanism includes four retaining rings arranged sequentially from the inside to the outside, with one side of each retaining ring fixedly connected to the inner side of the inner explosion-proof lamp shell. The flame guiding mechanism includes four flame guiding rings arranged sequentially from the inside to the outside, with their height increasing sequentially from the inside to the outside.

[0011] Preferably, a flame guide ring is fixedly connected to one side of the first baffle ring, and flame guide internal teeth are fixedly connected to the inner sides of the first baffle ring and the first flame guide ring in a uniformly distributed manner.

[0012] Preferably, a wave-shaped annular gasket is inserted between the first and second retaining rings, between the second and third retaining rings, and between the third and fourth retaining rings.

[0013] Preferably, one side of the second baffle ring is fixedly connected to the second flame guide ring, one side of the third baffle ring is fixedly connected to the third flame guide ring, and one side of the fourth baffle ring is fixedly connected to the fourth flame guide ring.

[0014] Preferably, one side of each of the flame guide rings 1, 2, 3 and 4 is curled inward.

[0015] Preferably, a mounting bracket is installed on the outer side of the external explosion-proof mechanism, a capacitor is installed on the inner side of the mounting bracket, the capacitor is connected to the lamp body through a circuit, and a protective net is fixedly connected to the outer side of the outer protective shell.

[0016] Preferably, an anti-glare lamp cover is installed at one port of the internal explosion-proof lamp housing.

[0017] The beneficial effects of this utility model are:

[0018] I. This utility model forms a multi-buffered structure by setting four layers of retaining rings (retaining ring one to retaining ring four) distributed sequentially from the inside to the outside and inserting wave-shaped annular gaskets. When the lamp body explodes, the shock wave needs to pass through the four layers of retaining rings and wave-shaped gaskets for energy conversion in sequence, and the propagation speed gradually decreases, which enhances the initial explosion-proof performance of the inner explosion-proof lamp housing. Even after experiencing multiple explosion impacts, the explosion-proof performance can still be guaranteed to be stable through the four layers of buffers, avoiding the problem of the explosion-proof mechanism's performance deteriorating due to frequent replacement of LED lamp boards.

[0019] II. The present invention, through the setting of the flame guiding mechanism, is composed of flame guiding rings one to four with increasing height. In conjunction with the flame guiding inner teeth that are curled to one side of the baffle ring, the flame and debris generated by the explosion can be guided in the opposite direction to the side closer to the lamp body. The flame and the shock wave collide inside the flame guiding ring, reducing the area directly baked by the anti-glare lamp cover and slowing down its aging speed. Attached Figure Description

Figure 1 For the sake of accuracy, the specific details should be as follows: Figure 1 The left side is the front. Figure 1 The right side is the rear; at the same time, as Figure 2 As shown, the horizontal direction is roughly defined as left and right, and the vertical direction is defined as up and down. If a specific orientation changes, the directional indication will also change accordingly.

[0032] This utility model provides an anti-glare explosion-proof LED lamp for mining, including an outer explosion-proof mechanism 1, a lamp body mechanism 4 arranged inside the outer explosion-proof mechanism 1, and a buffer mechanism 5 and a flame guiding mechanism 6 arranged inside the lamp body mechanism 4.

[0033] The external explosion-proof mechanism 1 includes an outer protective shell 11 and a heat dissipation mounting box 13 installed inside the outer protective shell 11;

[0034] The lamp body mechanism 4 includes an inner explosion-proof lamp housing 41 and a lamp body 42 installed inside the inner explosion-proof lamp housing 41. The inner explosion-proof lamp housing 41 is installed on the inner side of the heat dissipation mounting box 13 by bolts, and the buffer mechanism 5 is located on the outer periphery of the lamp body 42.

[0035] The buffer mechanism 5 includes a first retaining ring 51, a second retaining ring 52, a third retaining ring 53, and a fourth retaining ring 54 arranged sequentially from the inside to the outside. One side of each of the first retaining ring 51, the second retaining ring 52, the third retaining ring 53, and the fourth retaining ring 54 is fixedly connected to the inside of the inner explosion-proof lamp housing 41.

[0036] The flame guiding mechanism 6 includes flame guiding ring 1 61, flame guiding ring 2 62, flame guiding ring 3 63 and flame guiding ring 4 64 distributed from the inside to the outside, and the height increases sequentially from the inside to the outside.

[0037] The external explosion-proof mechanism 1, the lamp body mechanism 4, the mounting bracket 2, and the capacitor 3 constitute the anti-glare explosion-proof mining lamp in the prior art; the heat dissipation mounting box 13 has a large number of fins for heat dissipation after contacting the outer periphery of the internal explosion-proof lamp housing 41.

[0038] In a further embodiment, a flame guide ring 61 is fixedly connected to one side of the baffle ring 51, and flame guide internal teeth 65 are fixedly connected to the inner sides of the baffle ring 51 and the flame guide ring 61.

[0039] In this embodiment, the inner teeth 65 of the flame guide are all tilted to one side, thereby cooperating with the curved flame guide ring 61 so that the flame and shock wave can be partially reflected back.

[0040] In a further embodiment, a wave-shaped annular gasket 55 is inserted between retaining ring 1 51 and retaining ring 2 52, between retaining ring 2 52 and retaining ring 3 53, and between retaining ring 3 53 and retaining ring 4 54.

[0041] In this embodiment, the wave-shaped annular gasket 55 is made of rubber with elastic deformation capability, which can absorb the impact force generated by the explosion of the lamp body 42 in the event of a malfunction.

[0042] In a further embodiment, one side of the second baffle ring 52 is fixedly connected to the second flame guide ring 62, one side of the third baffle ring 53 is fixedly connected to the third flame guide ring 63, and one side of the fourth baffle ring 54 is fixedly connected to the fourth flame guide ring 64.

[0043] In this embodiment, the buffer mechanism 5 and the flame guiding mechanism 6 are interconnected in each turn to form a baffle plate that increases sequentially from the inside to the outside, and the gaps are equal. This allows for multiple buffering operations. In addition, a diamond-like carbon film is prepared on the surface of the baffle plate using chemical vapor deposition (CVD) to improve its corrosion resistance.

[0044] In a further embodiment, one side of each of the flame guide ring 61, flame guide ring 62, flame guide ring 63, and flame guide ring 64 is curled inward.

[0045] In this embodiment, the curled portion allows it to guide the flame and debris in the opposite direction.

[0046] In a further embodiment, an installation bracket 2 is installed on the outer side of the outer explosion-proof mechanism 1, a capacitor 3 is installed on the inner side of the installation bracket 2, the capacitor 3 is connected to the lamp body 42 through a circuit, and a protective net 12 is fixedly connected to the outer side of the outer protective shell 11.

[0047] In this embodiment, the mounting frame 2 is a support frame used for installation inside the mine tunnel, and the capacitor 3 is used to connect the external power supply line to the lamp body 42.

[0048] In a further embodiment, an anti-glare lamp cover 43 is installed at one port of the internal explosion-proof lamp housing 41.

[0049] In this embodiment, the anti-glare lampshade 43 is a thick tempered borosilicate glass with a regular hexagonal prism anti-glare feature.

[0050] The working principle of this utility model is as follows:

[0051] When the lamp body 42 explodes due to long-term use and malfunction, the impact force generated by the explosion will spread from the inside to the outside. During the diffusion process, the impact force will be blocked by the first baffle ring 51, the second baffle ring 52, the third baffle ring 53 and the fourth baffle ring 54 in sequence, as well as the stepped flame guide rings 61, 62, 63 and 64. During the blocking, there are wave-shaped annular gaskets 55 inserted between the first baffle ring 51 and the second baffle ring 52, between the second baffle ring 52 and the third baffle ring 53, and between the third baffle ring 53 and the fourth baffle ring 54. As a result, the explosion shock wave needs to undergo four energy conversions, and the propagation speed gradually decreases. This can enhance the initial explosion-proof performance of the inner explosion-proof lamp housing 41. After multiple explosion impacts of the lamp body 42, its explosion-proof performance can still be guaranteed by the four layers of buffer.

[0052] When the lamp body 42 malfunctions and causes an explosion, the resulting flame will be guided inward by the flame guide teeth 65 on the inner side of the baffle ring 51 and the flame guide ring 61 to counteract the erupting flame and shock wave, thereby reducing the area of ​​the flame baking the inner side of the anti-glare lamp cover 43. At the same time, the flame guide teeth 65 are in an inclined state, so that the debris mixed in with the flame can be guided to the side closer to the lamp body 42. This makes it easier to clean when replacing the lamp body 42, thereby extending the aging of the anti-glare lamp cover 43 and extending its service life.

[0053] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
