Description

Technical Field

[0001] The invention belongs to the technical field of explosion-proof lamps, in particular to a safety explosion-proof lamp. Background Art

[0002] In modern industrial production and special operations, explosion-proof safety lamps, as key equipment for ensuring safe production, are widely used in areas with flammable and explosive hazards, such as the petroleum, chemical, mining, and food processing industries. With the continuous expansion of industrial production and the increasing emphasis on safe production, higher requirements are being placed on the performance and reliability of explosion-proof safety lamps.

[0003] The core function of explosion-proof lamps is to prevent arcs, sparks, and high temperatures generated within the lamp from igniting flammable gases or dust in the surrounding environment, thereby preventing explosions. Their operating principles are based on a variety of explosion-proof technologies. For example, flameproof lamps use a robust casing to withstand internal explosion pressure and prevent the spread of flames; increased safety lamps incorporate additional measures to improve the safety of electrical equipment under normal and fault conditions; and intrinsically safe lamps ensure that the energy generated by the circuit under specified conditions is insufficient to ignite an explosive atmosphere.

[0004] However, explosion-proof lamps face numerous challenges and problems in dusty environments. Firstly, dust has an absorptive nature. During the production process, large amounts of dust can adhere to the lamp's surface, forming a thick layer. This not only severely reduces the lamp's light transmittance, significantly reducing illumination brightness, but also makes it difficult for workers to clearly see the work area, increasing the risk of operational errors and safety accidents.

[0005] Furthermore, dust particles in dusty environments vary in size, and some fine dust particles can enter the lamp through tiny gaps or vents in the lamp housing. Once dust accumulates to a certain level, sparks or high temperatures can form inside the lamp, potentially triggering a dust explosion, posing a serious threat to the entire operating environment and personnel safety.

The safety explosion-proof lamp described in the present invention can prevent dust from directly adhering to the lamp shell, causing some fine dust to enter the interior of the explosion-proof lamp body and increase the risk of explosion of the explosion-proof lamp body, and at the same time, introduce gas into the protective tube to dissipate heat for the explosion-proof lamp body, thereby preventing the temperature of the explosion-proof lamp body from being too high and reducing the service life of the explosion-proof lamp body.

[0033] 2. The safety explosion-proof lamp described in the present invention can blow the dust below the explosion-proof lamp body to move by ejecting gas from the nozzle arranged on the arc-shaped guard rod, so that the dust is away from the lampshade. Due to the presence of the nozzle, the range of the jet is increased, and the dust below the lampshade is further blown away; when the arc-shaped guard rod rotates following the second annular plate, the nozzle will also rotate, and the ejected gas will also rotate at the same time. After the ejected gas rotates, it can eject the gas downward while rotating, thereby further increasing the range of the jet and blowing away the dust below the lampshade, thereby reducing the amount of dust adsorbed on the lampshade.

[0034] 3. The safety explosion-proof lamp described in the present invention has heat dissipation fins provided in the protective tube. The heat dissipation fins can absorb the heat on the explosion-proof lamp body. At the same time, since the heat dissipation fins are spiral, the gas entering the protective tube will flow downward along the heat dissipation fins.

At the same time, the flowing gas will drive the heat on the heat dissipation fins. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0049] As an embodiment of the present invention, Figures 1 to 11 As shown, the safety explosion-proof lamp of the present invention includes an explosion-proof lamp body; the explosion-proof lamp body includes a protective mounting mechanism;

[0050] The protective installation mechanism includes a protective tube 1, and the bottom of the protective tube 1 is open; a through slot 61 is opened on the top of the protective tube 1; a first wire tube 11 is installed on the top of the protective tube 1 by bolts, and the through slot 61 is located inside the first wire tube 11;

[0051] A second wire pipe 12 is connected above the first wire pipe 11, and the second wire pipe 12 is installed on the ceiling and extends to the outside dust-free environment; wires pass through the second wire pipe 12; a filter can be provided at the end of the second wire pipe 12;

[0052] An air pump 13 is provided on the outer ring of the through groove 61, and the air pump 13 is installed in the protective tube 1; the air inlet pipe on the air pump 13 extends into the through groove, and the air outlet pipe on the air pump 13 is located in the protective tube 1;

[0053] A first annular plate 2 is fixed to the bottom of the protective tube 1; a first annular groove 21 is formed inside the first annular plate 2; and evenly arranged oblique holes 22 are formed on the upper surface of the first annular plate 2, and the oblique holes 22 are connected to the first annular groove 21;

[0054] A second annular plate 23 is slidably connected to the first annular groove 21; the second annular plate 23 partially extends out of the first annular groove 21; a second annular groove 24 is formed on the side of the second annular plate 23 facing the oblique hole 22;

[0055] The outer surface of the second annular plate 23 is fixed with push blocks 25 arranged evenly; the inner surface of the second annular plate 23 is fixed with two connecting plates 26; an arc-shaped plate 27 is fixed to the two connecting plates 26; and an air outlet 28 is opened on the second annular groove 24.

[0056] In this embodiment, the explosion-proof lamp body further includes a lamp housing 3; an annular end cover 31 is fixedly installed below the lamp housing 3 by bolts; a lampshade 32 is installed between the lamp housing 3 and the annular end cover 31; a gap is left between the protective tube 1 and the annular end cover 31;

[0057] A circuit board is installed in the lamp housing 3; a power line is installed on the circuit board, and the power line passes through the through slot 61 and passes through the first wire tube 11 to connect with the wire in the second wire tube 12;

[0058] A lamp panel 33 is installed at the bottom of the circuit board, and the lamp panel 33 is located above the lampshade 32; the bottom of the annular end cover 31 is in contact with the top of the first annular plate 2; the arc plate 27 is in contact with the surface of the lampshade 32;

[0059] In this embodiment, the bottom surface of the second annular plate 23 is provided with evenly arranged tooth grooves 43 in an annular shape;

[0060] A power compartment 4 is mounted at the bottom of the first annular plate 2; a motor 41 is mounted in the power compartment 4; a gear 42 is mounted on the drive shaft of the motor 41; the gear 42 partially extends to one side of the tooth groove 43 and meshes with the tooth groove 43;

[0061] During implementation, the explosion-proof lamp body is installed in a suitable position. During installation, first, the power cord on the explosion-proof lamp body is passed through the first wire tube 11, and then the power cord is connected to the wire in the second wire tube 12. At the same time, the power cord on the air pump 13 is passed through the first wire tube 11 and connected to the wire; then one end of the first wire tube 11 is installed on the second wire tube 12, and the other end is installed on the protective tube 1. Then the explosion-proof lamp body can be put into use to achieve the lighting function;

[0062] 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 protective tube 1, the protective tube 1 can block the dust, preventing some dust from directly adhering to the surface of the explosion-proof lamp body, and at the same time preventing some fine dust from entering the interior of the explosion-proof lamp body. At the same time, when the explosion-proof lamp body is powered on, the air pump 13 is also powered on, and the air pump 13 will pump air when it works. The air pump 13 will draw the gas in the first wire tube 11 into the interior of the protective tube 1 through the through groove 61. The first conduit 11 is connected to the second conduit 12, and the second conduit 12 extends to the outside dust-free environment. Therefore, the second conduit 12 and the external gas will be drawn into the first conduit 11, and then enter the protective tube 1 through the through groove 61. Since a filter can be provided at the end of the second conduit 12, dust can also be filtered. When the gas enters the protective tube 1, it will flow downward along the protective tube 1 and the lamp housing 3. The downward-flowing gas will take away the heat from the explosion-proof lamp body, thereby achieving a heat dissipation effect on the explosion-proof lamp body.

[0063] 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 oblique holes 22, the gas will be blown into the first annular groove 21 through the oblique holes 22. The second annular plate 23 rotatably connected in the first annular groove 21 is fixed with evenly arranged push blocks 25. Therefore, the gas blown obliquely into the first annular groove 21 will push the push blocks 25 to move, and the push blocks 25 will drive the second annular plate 23 to move as a whole. In the process of the overall movement of the second annular plate 23, the curved plate 27 will be driven to move through the connecting plate 26. The moving curved plate 27 will move along the lampshade 32, so as to scrape the surface of the lampshade 32, thereby scraping off the dust adsorbed on the lampshade 32, and preventing the dust from being adsorbed on the lampshade 32, which will cause 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 gas outlet 28.

[0064] During implementation, by installing a power compartment 4 at the bottom of the first annular plate 2, the motor 41 in the power compartment 4 drives the gear 42 to rotate, and the rotating gear 42 engages with the tooth groove 43 provided at the bottom of the second annular plate 23, thereby driving the entire second annular plate 23 to rotate. In this process, the rotation speed of the second annular plate 23 and the arc-shaped plate 27 can be adjusted by the rotation speed of the motor 41, and at the same time, power can be provided to the second annular plate 23.

[0065] In general, by installing the explosion-proof lamp body in the protective tube 1, dust can be prevented from directly adhering to the lamp housing 3, causing some fine dust to enter the interior of the explosion-proof lamp body, increasing the risk of explosion of the explosion-proof lamp body. At the same time, introducing gas into the protective tube 1 can dissipate heat for the explosion-proof lamp body, avoid the explosion-proof lamp body from being overheated, and reduce the service life of the explosion-proof lamp body. At the same time, when the gas is introduced, the gas will enter the protective tube 1 through the first wire tube 11 and the second wire tube 12. Therefore, during the flow of gas, the wires and power cords can also be cooled. At the same time, by controlling the second annular plate 23 to drive the arc plate 27 to rotate, the surface of the lampshade 32 can be scraped, thereby scraping off the dust adsorbed on the lampshade 32, avoiding dust adsorbed on the lampshade 32, causing the illumination of the explosion-proof lamp body to decrease.

[0066] As an embodiment 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 lampshade 32;

[0067] In this embodiment, the arc-shaped guard bar 5 is a tubular structure; the arc-shaped guard bar 5 is connected to the air outlet 28 on the second annular plate 23;

[0068] The arc-shaped guard bar 5 is provided with uniformly arranged air-jet holes 51; the air-jet holes 51 are all vertically downward; and nozzles are installed in the air-jet holes 51;

[0069] In this embodiment, the side of the arc plate 27 close to the lampshade 32 is tapered;

[0070] The arc-shaped plate 27 is made of rubber material; an air cavity 271 is defined inside the arc-shaped plate 27; an air passage 261 is defined inside the connecting plate 26, and one side of the air passage 261 is connected to the second annular groove 24, and the other side is connected to the air cavity 271 in the arc-shaped plate 27;

[0071] The arc-shaped plate 27 is provided with evenly arranged blowing holes 272 on one side close to the lampshade 32;

[0072] During implementation, since a plurality of arc-shaped guard bars 5 are fixed to the second annular plate 23, the arc-shaped guard bars 5 can protect the lampshade 32, thereby preventing foreign objects from directly colliding with the lampshade 32, causing damage to the lampshade 32 and the risk of explosion. At the same time, when the second annular plate 23 rotates, the arc-shaped guard bars 5 can be driven to rotate, and the rotating arc-shaped guard bars 5 can rotate along the lampshade 32 while protecting the lampshade 32.

[0073] During implementation, since the arc-shaped guard rod 5 is a tubular structure and is connected to 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 the arc-shaped guard rod 5 is provided with uniformly arranged air injection holes 51, the gas will be ejected downward through the air injection holes 51. The ejected gas can blow the dust located below the explosion-proof lamp body to move, so that the dust is away from the lampshade 32. At the same time, since a nozzle is provided in the air injection hole 51, when the gas passes through the nozzle, the range of the air injection will be increased, and the dust located below the lampshade 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 ejected gas will also rotate. When the ejected gas rotates, it can rotate and eject the air downward, thereby further increasing the range of the air injection and blowing away the dust located below the lampshade 32, thereby reducing the amount of dust adsorbed on the lampshade 32.

[0074] During implementation, since the air cavity 271 in the curved plate 27 is connected to the second annular groove 24 through the air channel 261 in the connecting plate 26, the gas in the second annular groove 24 will also enter the air cavity 271 inside the curved plate 27 through the air channel 261, and then be blown out through the blowing hole 272. When the gas is blown out from the blowing hole 272, the gas will act on the lampshade 32. At the same time, if dust accumulates in the process of the curved plate 27 scraping the lampshade 32, the blown gas can also blow off the accumulated dust, thereby preventing the dust from accumulating on the curved plate 27.

[0075] Generally speaking, by ejecting gas from the nozzles provided on the arc-shaped guard rod 5, the dust below the explosion-proof lamp body can be blown away, so that the dust is moved away from the lampshade 32. Due to the presence of the nozzles, the range of the jet is increased, and the dust below the lampshade 32 is further blown away; when the arc-shaped guard rod 5 rotates following the second annular plate 23, the nozzles will also rotate, and the ejected gas will also rotate. After the ejected gas rotates, it can eject the gas downward while rotating, thereby further increasing the range of the jet and blowing away the dust below the lampshade 32, thereby reducing the amount of dust adsorbed on the lampshade 32.

[0076] As an embodiment of the present invention, the protective tube 1 is provided with a heat dissipation fin 14; the heat dissipation fin 14 is spiral-shaped;

[0077] The heat dissipation fins 14 slide inside the protective tube 1; the heat dissipation fins 14 are sleeved on the outer ring of the lamp housing 3;

[0078] In this embodiment, a round cover 6 is provided on the top of the protective tube 1; the through slot 61 is opened on the round cover 6;

[0079] The first wire tube 11 is also installed on the round cover 6; the round cover 6 is fixed on the top of the protective tube 1 by bolts;

[0080] The top of the round cover 6 is threadedly engaged with evenly arranged threaded rods 62, and the threaded rods 62 are located outside the first wire tube 11; the threaded rods 62 extend into the interior of the protective tube 1 and are used to fix the explosion-proof lamp body;

[0081] In this embodiment, a sealing ring is provided on the side of the first annular plate 2 that contacts the annular end cover 31, and the sealing ring is provided on the first annular plate 2;

[0082] The second annular plate 23 is located in the first annular groove 21 and is also provided with sealing rings on its upper and lower sides, and the sealing rings are provided on the second annular plate 23;

[0083] During implementation, since the protective tube 1 is provided with heat dissipating fins 14, the heat dissipating fins 14 can absorb the heat on the explosion-proof lamp body. At the same time, since the heat dissipating fins 14 are spiral-shaped, the gas entering the protective tube 1 will flow downward along the heat dissipating fins 14. During the downward flow of the gas, it can pass through the outer surface of the lamp housing 3 in sequence, dissipating the heat of the explosion-proof lamp body more evenly. At the same time, the flowing gas will drive the heat on the heat dissipating fins 14.

[0084] During the implementation process, since a round cover 6 is provided on the top of the protective tube 1, when installing the explosion-proof lamp body, the round cover 6 is first removed, and then the heat dissipation fins 14 are placed inside the protective tube 1, and then the explosion-proof lamp body is placed into the protective tube 1, and the explosion-proof lamp body is located on the inner circle of the heat dissipation fins 14, and then the power cord is passed through the through groove 61, and then the round cover 6 is installed on the top of the protective tube 1 by bolts, and then the evenly arranged threaded rods 62 are rotated, and the threaded rods 62 will gradually penetrate into the protective tube 1 and gradually fix the explosion-proof lamp body, thereby avoiding the explosion-proof lamp body from shaking;

[0085] 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 avoid gas leakage. At the same time, since sealing rings are also provided on the upper and lower sides of the second annular plate 23, the second annular plate 23 can be sealed to avoid gas leakage during the rotation of the second annular plate 23.
