Description

Technical Field

[0001] The present invention belongs to the technical field of explosion-proof lamps, and specifically relates to a safety explosion-proof lamp. Background Art

[0002] In modern industrial production and special operation scenarios, safety explosion-proof lamps, as key equipment for ensuring safe production, are widely used in places with explosive and flammable hazards such as petroleum, chemical industry, mining, and food processing. With the continuous expansion of industrial production scale and the increasing emphasis on safe production, higher requirements are put forward for the performance and reliability of safety explosion-proof lamps. The core function of an explosion-proof lamp is to prevent electric arcs, sparks, and high temperatures generated inside the lamp from igniting combustible gases or dust in the surrounding environment, thereby avoiding the occurrence of explosion accidents. Its working principle is based on various explosion-proof technologies. For example, the flameproof type withstands the internal explosion pressure through a sturdy shell and prevents the spread of flames; the increased safety type takes additional measures for electrical equipment to improve its safety under normal and fault conditions; the intrinsically safe type ensures that the energy generated by the circuit under specified conditions is not sufficient to ignite the explosive gas environment, etc. However, in a dust environment, explosion-proof lamps face many challenges and problems. On the one hand, dust has adsorbability. During the production process, a large amount of dust will adsorb on the surface of the explosion-proof lamp, forming a thick dust layer. This will not only seriously affect the light transmittance of the lamp, resulting in a significant decrease in illumination brightness, making it difficult for operators to see the working area clearly, but also increasing the risk of operation errors and safety accidents. On the other hand, the dust particles in the dust environment vary in size. Some fine dust particles may enter the interior of the lamp through small gaps or vents in the lamp housing. Once the dust accumulates to a certain extent inside the lamp, when an electric spark or high temperature is generated inside the lamp, it may trigger a dust explosion, which will pose a serious threat to the entire operation environment and personnel safety.

[0012] The beneficial effects of the present invention are as follows: 1. For a safety explosion-proof lamp described in the present invention, by installing the explosion-proof lamp body inside the protection cylinder, it is possible to prevent dust from directly adhering to the lamp housing, resulting in some fine dust entering the inside of the explosion-proof lamp body and increasing the risk of explosion of the explosion-proof lamp body. At the same time, introducing gas into the protection cylinder can dissipate heat from the explosion-proof lamp body, prevent the temperature of the explosion-proof lamp body from being too high and reduce the service life of the explosion-proof lamp body.

Due to the existence of the nozzles, the range of gas spraying will be increased, and the dust located below the lamp cover will be further blown away; when the arc-shaped guard bar rotates with the second annular plate, the nozzles will also rotate, and the sprayed gas will also rotate.

During the process of the gas flowing downward, it can pass through the outer surface of the lamp housing in turn, and dissipate heat from the explosion-proof lamp body more evenly. At the same time, the flowing gas will drive the heat on the heat dissipation fins. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] As an embodiment of the present invention, as Figures 1 to 11 shown, a safety explosion-proof lamp described in the present invention includes an explosion-proof lamp body; the explosion-proof lamp body includes a protection and installation mechanism; The protection and installation mechanism includes a protection cylinder 1, and the bottom of the protection cylinder 1 is open; a through groove 61 is opened at the top of the protection cylinder 1; the top of the protection cylinder 1 is installed with a first pipeline 11 through bolts, and the through groove 61 is located inside the first pipeline 11; A second pipeline 12 is communicated above the first pipeline 11, and the second pipeline 12 is installed on the ceiling and extends to a dust-free environment outside; an electric wire passes through the second pipeline 12; a filter screen can be arranged at the end of the second pipeline 12; An air pump 13 is arranged outside the through groove 61, and the air pump 13 is installed inside the protection cylinder 1; the intake pipe on the air pump 13 extends into the through groove, and the exhaust pipe on the air pump 13 is located inside the protection cylinder 1; The bottom of the protection cylinder 1 is fixed with a first annular plate 2; a first annular groove 21 is opened inside the first annular plate 2; uniformly arranged oblique holes 22 are opened on the upper surface of the first annular plate 2, and the oblique holes 22 are communicated with the first annular groove 21; A second annular plate 23 is slidably connected in the first annular groove 21; a part of the second annular plate 23 extends out of the first annular groove 21; a second annular groove 24 is opened on the side of the second annular plate 23 facing the oblique hole 22; Uniformly arranged push blocks 25 are fixed on the outer circumferential surface of the second annular plate 23; two connecting plates 26 are fixed on the inner circumferential surface of the second annular plate 23; an arc-shaped plate 27 is jointly fixed on the two connecting plates 26; an air outlet 28 is opened on the second annular groove 24; In this embodiment, the explosion-proof lamp body further includes a lamp housing 3; a ring end cover 31 is fixedly installed below the lamp housing 3 by bolts; a lamp cover 32 is installed between the lamp housing 3 and the ring end cover 31; a spacing is left between the protection cylinder 1 and the ring end cover 31; A circuit board is installed inside the lamp housing 3; a power cord is installed on the circuit board, and the power cord passes through the through groove 61 and passes through the first conduit 11 to be connected to the wire inside the second conduit 12; A lamp panel 33 is installed at the bottom of the circuit board, and the lamp panel 33 is located above the lamp cover 32; the bottom of the ring end cover 31 is in contact with the top of the first ring plate 2; the arc plate 27 is in contact with the surface of the lamp cover 32; In this embodiment, evenly arranged tooth grooves 43 are annularly formed on the bottom surface of the second ring plate 23; A power bin 4 is installed at the bottom of the first ring plate 2; a motor 41 is installed inside the power bin 4; a gear 42 is installed on the drive shaft of the motor 41; a part of the gear 42 extends to one side of the tooth groove 43 and meshes with the tooth groove 43; During implementation, install the explosion-proof lamp body at a suitable position. When installing, first pass the power cord on the explosion-proof lamp body into the first conduit 11, then connect the power cord to the wire inside the second conduit 12, and at the same time pass the power cord on the air pump 13 through the first conduit 11 and connect it to the wire; then install one end of the first conduit 11 on the second conduit 12 and the other end on the protection cylinder 1, and then the explosion-proof lamp body can be put into use to achieve the function of lighting; During the implementation process, if there is dust in the environment where the explosion-proof lamp body is located, since the explosion-proof lamp body is located inside the protection cylinder 1, the protection cylinder 1 can block the dust, avoid some dust directly adhering to the surface of the explosion-proof lamp body, and at the same time can prevent some fine dust from entering the inside of the explosion-proof lamp body. At the same time, when the explosion-proof lamp body is powered on and used, the air pump 13 is also powered on. When the air pump 13 works, it will draw air. The air pump 13 will draw the gas in the first conduit 11 into the protection cylinder 1 through the through groove 61. Since the first conduit 11 is connected to the second conduit 12 and the second conduit 12 extends to the dust-free environment outside, the second conduit 12 and the outside gas will be drawn into the first conduit 11 and then enter the protection cylinder 1 through the through groove 61. Since a filter screen can be arranged at the end of the second conduit 12, the dust can also be filtered; when the gas enters the protection cylinder 1, it will flow downward along the protection cylinder 1 and the lamp housing 3, and the downward flowing gas will take away the heat on the explosion-proof lamp body, thereby achieving the effect of dissipating heat for the explosion-proof lamp body; During the implementation process, as the gas gradually flows, the gas will flow to the position of the first annular plate 2. Since the first annular plate 2 is provided with evenly arranged inclined holes 22, the gas will be blown into the first annular groove 21 through the inclined holes 22. Fixed on the second annular plate 23 rotatably connected in the first annular groove 21 are evenly arranged push blocks 25. Therefore, the gas blowing obliquely into the first annular groove 21 will push the push blocks 25 to move, and the push blocks 25 will drive the entire second annular plate 23 to move. During the process of the entire movement of the second annular plate 23, it will drive the arc-shaped plate 27 to move through the connecting plate 26. The moving arc-shaped plate 27 will move along the lamp cover 32, so as to scrape the surface of the lamp cover 32, thereby scraping off the dust adsorbed on the lamp cover 32, preventing dust from being adsorbed on the lamp cover 32 and causing the illumination of the explosion-proof lamp body to decrease. The gas entering the first annular groove 21 will enter the second annular groove 24 and then be discharged through the air outlet 28; During the implementation process, by installing a power supply chamber 4 at the bottom of the first annular plate 2, the motor 41 in the power supply chamber 4 will drive the gear 42 to rotate. The rotating gear 42 meshes with the tooth groove 43 opened at the bottom of the second annular plate 23, thereby pushing the entire second annular plate 23 to rotate. During this process, the rotation speed of the motor 41 can be used to adjust the rotation speed of the second annular plate 23 and the arc-shaped plate 27, and at the same time, power can be provided for the second annular plate 23; Generally speaking, by installing the explosion-proof lamp body in the protective cylinder 1, it is possible to prevent dust from directly adhering to the lamp shell 3, resulting in some fine dust entering the interior of the explosion-proof lamp body and increasing the risk of explosion of the explosion-proof lamp body. At the same time, introducing gas into the protective cylinder 1 can dissipate heat from the explosion-proof lamp body, preventing the explosion-proof lamp body from being too hot and reducing the service life of the explosion-proof lamp body. At the same time, when introducing gas, the gas will enter the protective cylinder 1 through the first wire tube 11 and the second wire tube 12. Therefore, during the flow of the gas, heat can also be dissipated from the wires and power cords. At the same time, by controlling the second annular plate 23 to drive the arc-shaped plate 27 to rotate, the surface of the lamp cover 32 can be scraped, thereby scraping off the dust adsorbed on the lamp cover 32 and preventing dust from being adsorbed on the lamp cover 32 and causing the illumination of the explosion-proof lamp body to decrease.

[0020] As an implementation manner of the present invention, a plurality of arc-shaped guard bars 5 are fixed on the second annular plate 23, and the arc-shaped guard bars 5 are used to protect the lamp cover 32; In this implementation manner, the arc-shaped guard bar 5 is of a tubular structure; the arc-shaped guard bar 5 is communicated with the air outlet 28 on the second annular plate 23; The arc-shaped guard bar 5 is provided with evenly arranged air injection holes 51; the air injection holes 51 are all vertically downward; nozzles are installed in the air injection holes 51; In this implementation manner, the side of the arc-shaped plate 27 close to the lamp cover 32 is conical; The arc-shaped plate 27 is made of rubber material; an air cavity 271 is formed inside the arc-shaped plate 27; an air passage 261 is formed inside the connecting plate 26, one side of the air passage 261 communicates with the second annular groove 24, and the other side communicates with the air cavity 271 inside the arc-shaped plate 27; A uniformly arranged blowing hole 272 is formed on one side of the arc-shaped plate 27 close to the lamp cover 32; During implementation, since a plurality of arc-shaped guard rods 5 are fixed on the second annular plate 23, the existence of the arc-shaped guard rods 5 can protect the lamp cover 32, thereby preventing an external object from directly colliding with the lamp cover 32, resulting in the risk of explosion due to damage to the lamp cover 32. At the same time, when the second annular plate 23 rotates, it can drive the arc-shaped guard rods 5 to rotate. The rotating arc-shaped guard rods 5 can rotate along the lamp cover 32 while protecting the lamp cover 32; During the implementation process, since the arc-shaped guard rod 5 is a tubular structure and communicates with the second annular plate 23 and the air outlet 28, the gas flowing out of the second annular groove 24 will enter the arc-shaped guard rod 5. Since uniformly arranged air jet holes 51 are formed on the arc-shaped guard rod 5, the gas will jet downward through the air jet holes 51. The jetted gas can blow the dust located below the explosion-proof lamp body to move, so that the dust is far away from the position of the lamp cover 32. At the same time, since a nozzle is provided in the air jet hole 51, when the gas passes through the nozzle, the range of the jet will increase, and the dust located below the lamp cover 32 will be further blown away; when the arc-shaped guard rod 5 rotates following the second annular plate 23, the nozzle will also rotate, and the jetted gas will also rotate. When the jetted gas rotates, it can jet downward while rotating, thereby further increasing the range of the jet and blowing away the dust located below the lamp cover 32, so that the amount of dust adsorbed on the lamp cover 32 can be reduced; During the implementation process, since the air cavity 271 inside the arc-shaped plate 27 communicates with the second annular groove 24 through the air passage 261 inside the connecting plate 26, the gas in the second annular groove 24 will also enter the air cavity 271 inside the arc-shaped plate 27 through the air passage 261, and then be blown out through the blowing hole 272. When the gas is blown out through the blowing hole 272, the gas will act on the lamp cover 32 at this time. At the same time, if dust accumulates during the process of the arc-shaped plate 27 rubbing against the lamp cover 32, the blown gas can also blow off the accumulated dust at this part, preventing the dust from accumulating on the arc-shaped plate 27; Generally speaking, by making the gas spray out from the nozzles provided on the arc-shaped guard rod 5, the dust located below the explosion-proof lamp body can be blown to move, so that the dust is far away from the position of the lamp cover 32. Due to the existence of the nozzles, the range of the jet gas will be increased, and the dust located below the lamp cover 32 will be further blown away; when the arc-shaped guard rod 5 rotates with the second annular plate 23, the nozzles will also rotate, and the sprayed gas will also rotate. After the sprayed gas rotates, it can spray downward while rotating, thereby further increasing the range of the jet gas and blowing away the dust located below the lamp cover 32, so that the amount of dust adsorbed on the lamp cover 32 can be reduced.

At the same time, since the heat dissipation fins 14 are spiral, the gas entering the protection cylinder 1 will flow downward along the heat dissipation fins 14. During the downward flow of the gas, it can pass through the outer surface of the lamp housing 3 in turn, and dissipate heat from the explosion-proof lamp body more evenly. At the same time, the flowing gas will drive the heat on the heat dissipation fins 14; During the implementation process, since a round cover 6 is provided at the top of the protection cylinder 1, when installing the explosion-proof lamp body, first remove the round cover 6, then place the heat dissipation fins 14 inside the protection cylinder 1, then put the explosion-proof lamp body into the protection cylinder 1, and make the explosion-proof lamp body located inside the inner circle of the heat dissipation fins 14. Then pass the power cord through the through groove 61, then install the round cover 6 on the top of the protection cylinder 1 by bolts, and then rotate the uniformly arranged threaded rods 62. The threaded rods 62 will gradually penetrate into the protection cylinder 1 and gradually fix the explosion-proof lamp body, so as to avoid the situation of the explosion-proof lamp body shaking; During the implementation process, since a sealing ring is provided between the annular end cover 31 and the first annular plate 2, the annular end cover 31 and the first annular plate 2 can be sealed to prevent gas leakage. At the same time, since sealing rings are also provided on both the upper and lower sides of the second annular plate 23, the second annular plate 23 can be sealed to prevent gas leakage during the rotation of the second annular plate 23.
