Description

Technical Field

[0001] This utility model relates to the field of industrial and mining lamp technology, specifically a high-temperature resistant and corrosion-resistant industrial and mining lamp. Background Technology

[0002] As the core lighting equipment in industrial settings such as mining, metallurgy, and chemical industries, industrial and mining lamps generally operate in environments characterized by high temperature, high humidity, strong corrosion, and high dust levels. When used in metallurgical workshops, the ambient temperature is high, while the air in chemical plant areas is filled with corrosive gases such as sulfides and chlorides. This makes it difficult for existing industrial and mining lamps to meet the long-term stable operation requirements of these scenarios during long-term use.

[0003] First, existing industrial and mining lamps lack sufficient heat management capabilities, making them prone to aging and failure of core components due to high temperatures. Furthermore, some existing industrial and mining lamps lack reliable pressure balancing mechanisms, and their sealing structures are susceptible to failure under alternating hot and cold temperatures. Under high-temperature conditions, the air inside the lamp expands due to heat, causing the air pressure to exceed that of the external environment. If exhaust cannot be timely, the excessively high pressure will compress the sealing structure at the connection points, leading to an expansion of the sealing gap. Conversely, when the lamp stops working or the ambient temperature drops, the cooling and contraction of the air inside the lamp creates negative pressure, generating a suction effect. This accelerates the penetration of external air containing corrosive media and dust into the inner cavity, further compromising the seal and making it difficult to completely prevent the penetration of corrosive media.

[0004] Therefore, this utility model provides a high-temperature resistant and corrosion-resistant industrial and mining lamp to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a high-temperature resistant and corrosion-resistant industrial and mining lamp, which solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant and corrosion-resistant industrial and mining lamp, comprising a dust cover and a rear cover, wherein a second connector is threaded onto the dust cover, a valve is provided on the outer side of the dust cover, an inner layer is provided inside the dust cover, the inner layer is filled with a mixture of activated alumina particles and activated carbon particles, the dust cover is made of polytetrafluoroethylene, the bottom end of the valve is located on the inner layer of the mixture of activated alumina particles and activated carbon particles, an mounting ring is provided on the outer side of the dust cover, the mounting ring is fixed to the dust cover by compression through the second connector, a heat sink is fixedly connected to the outer side of the mounting ring, and a heat conduction frame is provided on the outer side of the dust cover.

[0007] Preferably, the dust cover is threaded with a first connector, and the heat-conducting frame is made of copper.

[0008] Preferably, a third connector is fitted onto the rear cover, and the third connector is rotatably connected to a connecting bracket.

[0009] Preferably, the connecting bracket has a threaded wire on its outer side, the connecting bracket is threaded to the rear cover, and a power mounting base is bolted to the inner side of the connecting bracket.

[0010] Preferably, a power supply is installed on the power supply mounting base, and a light source board is fixedly connected to the end of the power supply away from the power supply mounting base.

[0011] Preferably, a dustproof glass, a diffuser and a reflector are sequentially installed and connected on the mounting ring, and the entire connection is sealed by a fluororubber and metal spring composite sealing ring;

[0012] Preferably, the surfaces of metal components such as power supply terminals are treated with chemical nickel-phosphorus alloy plating; and an anti-corrosion isolation plate is installed inside the electrical cavity to separate the power supply module from the light source module, preventing corrosion from spreading from one place to another.

[0013] Beneficial effects

[0014] This invention provides a high-temperature resistant and corrosion-resistant industrial and mining lamp. Compared with the prior art, it has the following advantages:

[0015] (1) A high-temperature resistant and corrosion-resistant industrial and mining lamp, wherein the activated alumina particles in the inner layer of the dust cover can efficiently trap moisture in the airflow, avoid electrochemical corrosion in high temperature and high humidity environment, and use activated carbon particles to adsorb corrosive gases such as sulfides and chlorides to prevent gas corrosion of the metal pins and circuits of the power supply and light source board. Furthermore, the dustproof glass on the mounting ring can intercept metal dust and coal dust carried by the external air, preventing dust from adhering to the valve diaphragm and affecting the sealing performance, or entering the inner cavity and accumulating on the circuit surface, causing a short circuit. The dual filtration makes the air entering the inner cavity clean and free from corrosion risk, and reduces the corrosion rate of internal components.

[0016] (2) A high-temperature resistant and corrosion-resistant industrial and mining lamp, through the valve, avoids the high pressure squeezing of the sealing structure, which causes the sealing ring to deform and the gap to expand. At the same time, it avoids the suction effect to accelerate the penetration of corrosive media. The avoidance of these two types of risks reduces the probability of sealing structure failure and ensures that the lamp maintains a good sealing state in the industrial and mining environment where high temperature and cold temperature frequently alternate.

[0017] (3) A high-temperature resistant and corrosion-resistant industrial and mining lamp, wherein the light source plate is in direct and close contact with the copper heat conduction frame, which can quickly conduct the heat generated by the light source plate to the heat conduction frame, and then to the heat sink through the mounting ring. The heat conduction path has no redundancy and the connection has no gaps, resulting in extremely low heat loss. In conjunction with the heat sink, the heat dissipation is accelerated by increasing the contact area, effectively suppressing the damage of high temperature to the components.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Please see Figure 1-6 A high-temperature resistant and corrosion-resistant industrial and mining lamp includes a dust cover 6 and a rear cover 13. A second connector 7 is threaded onto the dust cover 6. A valve 14 is provided on the outside of the dust cover 6. An inner layer is provided inside the dust cover 6, and the inner layer is filled with a mixture of activated alumina particles and activated carbon particles. The dust cover 6 is made of polytetrafluoroethylene. The bottom end of the valve 14 is located on the inner layer of the mixture of activated alumina particles and activated carbon particles. An installation ring 15 is provided on the outside of the dust cover 6. The installation ring 15 is fixed to the dust cover 6 by the second connector 7. A heat sink 4 is fixedly connected to the outside of the installation ring 15. A heat conduction frame 16 is provided on the outside of the dust cover 6.

[0028] The dust cover 6 is threaded with a first connector 5, and the heat conduction frame 16 is made of copper.

[0029] A third connector 12 is fitted onto the back cover 13, and the third connector 12 is rotatably connected to a connecting bracket 11.

[0030] The outer side of the connecting bracket 11 is provided with a threaded wire, and the connecting bracket 11 is threaded to the rear cover 13. The inner side of the connecting bracket 11 is bolted to the power mounting base 9.

[0031] A power supply 10 is installed on the power supply mounting base 9, and a light source board 8 is fixedly connected to the end of the power supply 10 away from the power supply mounting base 9.

[0032] The dustproof glass 3, the diffuser 2, and the reflector 1 are sequentially installed and connected on the mounting ring 15. All connections are sealed by a fluororubber and metal spring composite sealing ring.

[0033] Working process: After the power supply 10 is turned on, the power supply 10 supplies a stable working current to the light source board 8 which is fixedly connected to the side away from the mounting base. The light source board 8 then turns on and outputs lighting light. The light passes through the dustproof glass 3 and the diffuser 2 mounted on the mounting ring 15 in sequence, and is finally reflected by the reflector 1 and directed to the industrial and mining work area to meet the scene lighting needs. At the same time, the light source board 8 will generate a lot of heat during the continuous light emission process.

[0034] Heat conduction and dissipation:

[0035] The heat generated by the light source board 8 is quickly dissipated through a combination of directional conduction and efficient heat dissipation, preventing heat accumulation inside the dust cover 6.

[0036] The light source plate 8 and the copper heat conduction frame 16 on the outside of the dust cover 6 form a tight thermal contact, and the heat is directly conducted from the light source plate 8 to the heat conduction frame 16; then the heat conduction frame 16 transfers the heat to the mounting ring 15 that is fixedly connected to it;

[0037] The mounting ring 15 transfers the received heat to the radiator 4 fixedly connected to its outside. The radiator 4 dissipates the heat to the surrounding environment quickly by increasing the contact area with the outside air. The temperature inside the dust cover 6 can be significantly reduced, thus reducing the aging damage of high temperature to the dust cover 6 and the seals from the source.

[0038] Pressure imbalance:

[0039] Despite the aforementioned heat dissipation measures, the inner cavity of the dust cover 6 will still experience localized high-temperature zones due to the continuous heating of the light source board 8. This causes the air inside the cavity to expand due to heat. If the air pressure inside the cavity is not balanced and regulated in time, two types of risks that directly affect the reliability of the lamp will occur:

[0040] High pressure damage risk: When the air pressure inside the dust cover 6 is higher than the external ambient air pressure, the excessively high air pressure will exert outward pressure on the sealing structure of each connection part of the lamp, which may cause the fluororubber-metal spring composite sealing ring to deform, the sealing gap to widen, and lose its sealing and protective function.

[0041] When the lamp stops working or the ambient temperature drops, the air inside the dust cover 6 cools and contracts, and the air pressure is lower than the external ambient air pressure. At this time, a suction effect will be generated, which will accelerate the infiltration of air containing corrosive media such as sulfides and chlorides into the inner cavity, directly threatening the safety of core components such as the power supply 10 and the light source board 8.

[0042] Internal air pressure balance regulation mechanism:

[0043] To address the aforementioned risk of air pressure imbalance, dynamic balance of air pressure within the cavity is achieved through the coordinated design of valve 14 and the inner layer of dust cover 6.

[0044] When the air pressure inside the dust cover 6 is higher than the external ambient air pressure due to air expansion, the excess air inside the cavity will exert an outward thrust on the polytetrafluoroethylene membrane built into the valve 14, pushing the diaphragm to open, and the air will be discharged outward through the valve 14 channel; as the air is discharged, the air pressure inside the cavity gradually balances with the outside. When the air pressure is the same, the polytetrafluoroethylene membrane will automatically close due to its own elasticity, preventing external air from entering the dust cover 6 cavity in reverse;

[0045] When the light fixture stops working or the temperature drops, and the air pressure inside the dust cover 6 is lower than the external ambient air pressure, the external air will push open the PTFE membrane of valve 14 to replenish the internal cavity with air until the internal cavity and external air pressure are balanced. Throughout the adjustment process, the PTFE membrane of valve 14 only opens in one direction and is tightly fitted to the inner layer of dust cover 6 when closed, always maintaining the closed protection of the internal cavity and preventing the overall seal from being damaged by air pressure adjustment.

[0046] Corrosive media filtration:

[0047] Whether the air inside the dust cover 6 is exhausted to the outside or the outside air is replenished to the inside, all airflow must pass through the core filtration structure inside the dust cover 6 and complete double filtration before entering the next stage, completely blocking the penetration path of corrosive media.

[0048] The airflow first passes through the mixture of activated alumina particles and activated carbon particles filled in the inner layer of the dust cover 6. The activated alumina traps moisture in the airflow through physical adsorption properties, and then the activated carbon adsorbs corrosive gas molecules such as sulfides, chlorides, and sulfur dioxide in the airflow through its high specific surface area.

[0049] The airflow that has passed through the adsorption filter must also pass through the dustproof glass 3 on the mounting ring 15 to intercept solid pollutants such as metal dust and coal dust carried in the airflow. This prevents dust from adhering to the polytetrafluoroethylene membrane of the valve 14 and affecting the sealing performance, or from entering the inner cavity of the dust cover 6 and accumulating on the circuit surface of the power supply 10 and the light source board 8, causing a short circuit. Ultimately, this ensures that the air entering the inner cavity is clean and free from corrosion risks.
