Description
Technical Field
[0001] This utility model relates to the technical field of explosion-proof lights, and in particular to an explosion-proof light with a drainage structure. Background Technology
[0002] Explosion-proof lights mainly consist of a power supply unit, a heat sink, and an explosion-proof lamp housing. The heat sink is located between the power supply unit and the explosion-proof lamp housing. Heat sinks include finned heat sinks, finned heat sinks, crescent-shaped heat sinks, etc. The heat sink is exposed to the external environment. Multiple heat sinks in the heat sink form heat dissipation channels, which remove heat through natural convection or forced convection.
[0003] Explosion-proof lights have a wide range of applications. They can be used not only in hazardous locations with flammable gases or dust, such as petrochemical plants, oil platforms, gas stations, and oil pump rooms, but also in basements, underground pipe corridors, and outdoor environments. These environments often involve a certain level of humidity and water accumulation. Especially when used outdoors, rainwater can easily accumulate on the radiator during rainy weather. If the accumulated rainwater is not drained in time, it can lead to corrosion and damage to the radiator, reducing its heat dissipation efficiency and lifespan. In addition, rainwater may seep into the lamp housing, causing electrical malfunctions.
[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content
[0005] This invention addresses the problems mentioned above, such as the accumulation of rainwater in the radiators of existing explosion-proof lamps, which leads to damage and reduced heat dissipation efficiency and lifespan, as well as the possibility of rainwater seeping into the lamp box and causing electrical malfunctions.

[0007] An explosion-proof lamp with a drainage structure includes a lamp box and a heat sink disposed on the upper part of the lamp box. The heat sink includes a plurality of heat sinks, which are equally spaced. A first drainage channel is formed between any two heat sinks and the top of the lamp box. A baffle plate connected to the heat sinks on both sides is provided at the end of the first drainage channel.

[0008] As described above, in an explosion-proof lamp with a drainage structure, a water inlet pipe is provided on the outside of the water baffle, and a second drainage channel is provided inside the water inlet pipe and communicates with the first drainage channel.
[0009] As described above, in an explosion-proof lamp with a drainage structure, the water inlet pipe extends outward toward the outside of the lamp box, so that the outlet of the second drainage channel extends outward to the outside of the lamp box.
[0010] As described above, an explosion-proof lamp with a drainage structure has a flow guide inside the lamp box, a second drainage channel passing through the flow guide and communicating with the first drainage channel, and the outlet of the second drainage channel extending to the bottom of the lamp box.
[0011] As described above, an explosion-proof lamp with a drainage structure has an inclined bottom wall in the first drainage channel, the inclined bottom wall having a preset angle relative to the horizontal plane, and the water baffle plate located at the lower end of the inclined bottom wall.
[0012] As described above, an explosion-proof lamp with a drainage structure includes at least a first-end heat sink and an end heat sink disposed near both sides of the lamp housing, and a plurality of intermediate heat sinks disposed at equal intervals between the first-end heat sink and the end heat sink. Each intermediate heat sink has a through hole at its bottom that communicates with the first drainage channel. The first-end heat sink and the end heat sink each have a third drainage channel that communicates with the first drainage channel on the side away from the baffle plate, and the drain outlet of the third drainage channel extends to the outside of the lamp housing.
[0013] An explosion-proof lamp with a drainage structure as described above further includes a power supply box disposed on the upper part of the radiator. The bottom of the power supply box is provided with a first connecting part extending downward, and the top of the lamp box is provided with a second connecting part extending upward. The first connecting part and the second connecting part are correspondingly arranged. The heat sink includes at least a first heat sink, and the second connecting part is disposed in the first heat sink. The power supply box is mounted on the upper part of the radiator through the corresponding connection of the first connecting part and the second connecting part, and a heat dissipation air duct is formed between the power supply box and the radiator. The heat dissipation air duct is connected to each of the first drainage channels.
[0014] As described above, in an explosion-proof lamp with a drainage structure, each of the heat sinks has a raised portion at its top. The raised portion in the first heat sink has a clearance opening. The second connecting portion extends into the clearance opening, and the first connecting portion can extend into the clearance opening and connect with the second connecting portion accordingly.

[0018] 1. By setting a baffle plate at the end of the first drainage channel, and sealing the baffle plate with the heat sinks on both sides, the baffle plate restricts the water from flowing directly out along the first drainage channel and the outer contour of the lamp box, preventing water from entering the interior from the outside of the lamp box, thereby protecting the lighting components and other electrical components and extending the service life of the explosion-proof lamp.
[0019] 2. A second drainage channel is formed to facilitate the drainage of accumulated water, avoiding the assembly gap between the lamp box and the heat sink, and draining the water to the outside of the explosion-proof lamp.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0034] Example 1:
[0035] like Figure 1As shown in Figure 10, this utility model provides an explosion-proof lamp with a drainage structure. The explosion-proof lamp includes a lamp box 1 and a heat sink 2 disposed on the upper part of the lamp box 1. The lamp box 1 is used to install lighting elements such as LED beads. The heat sink 2 includes a plurality of heat sink fins 21, which are equally spaced. Any two heat sink fins 21 and the top of the lamp box 1 enclose a first drainage channel 23. The end of the first drainage channel 23 is provided with a baffle plate 3 connected to the heat sink fins 21 on both sides. The heat sink 2 also has a second drainage channel 4 communicating with the first drainage channel 23. The second drainage channel 4 is used to discharge the water accumulated in the first drainage channel 23 in a direction away from the explosion-proof lamp. The inlet 41 of the second drainage channel 4 is close to the baffle plate 3. The drainage structure of the explosion-proof lamp is composed of at least the first drainage channel 23, the baffle plate 3, and the second drainage channel 4. By setting the baffle plate 3 at the end of the first drainage channel 23, and sealing the baffle plate 3 with the heat sink fins 21 on both sides, the baffle plate 3 restricts the water accumulated from directly flowing along the heat sink fins 21. The first drainage channel 23 and the outer contour of the lamp box 1 allow water to flow out, preventing water from entering the interior of the lamp box 1 from the outside, thereby protecting the lighting components and other electrical parts and extending the service life of the explosion-proof lamp. Furthermore, by providing a second drainage channel 4 within the radiator 2, and forming a drainage channel for accumulated water, the water is drained away from the assembly gap between the lamp box 1 and the radiator 2 to the outside of the explosion-proof lamp, ensuring orderly drainage and preventing water from seeping into the lamp box 1 through the assembly gap, further protecting the explosion-proof lamp. Additionally, when the explosion-proof lamp is in use, a heat dissipation duct 7 is formed through the gap between each heat sink 21 to dissipate heat from the lamp. Each heat dissipation duct 7 is connected to each of the first drainage channels 23, meaning that air also flows within each of the first drainage channels 23. When a small amount of residual water remains in the first drainage channel 23, the heat emitted by the explosion-proof lamp and the air flowing within the first drainage channel 23 can evaporate the residual water, further protecting the radiator 2.
[0036] Optionally, the baffle plate 3 can be a single plate and sealed to the side of the radiator 2, directly covering each of the first drainage channels 23; or, the baffle plate 3 can be multiple smaller plates and correspondingly sealed between two adjacent heat sinks 21.
[0037] In addition, in order to ensure that each heat sink 21 can dissipate heat normally, the height of the baffle plate 3 should not be too high. Optionally, the height of the baffle plate 3 is about 1 / 6 to 1 / 3 of the height of the heat sink 21, so as to avoid the baffle plate 3 being too high and blocking the air flow in the heat dissipation duct 7. At the same time, it ensures that the baffle plate 3 can block most of the water and use the second drainage channel 4 to drain the water in an orderly manner.
[0038] Optional, such as Figure 2 As shown, each of the heat sinks 21 is equally spaced along the length of the lamp box 1, and each of the heat sinks 21 extends along the width of the lamp box 1 to form the length of the heat sink 21, thereby increasing the heat dissipation area. Further optionally, each of the heat sinks 21 may be provided with fins, slats, or other shapes.
[0039] Optional, such as Figure 2 As shown, the lamp box 1 includes a detachably connected top shell 101 and a bottom shell 102, which enclose a space for accommodating the lighting element. The heat sink 2 is provided on the top shell 101.
[0040] Optionally, the top shell 101 is integrally formed with the heat sink 2 to improve the thermal conductivity between the lamp box 1 and each of the heat sinks 21, thereby improving the heat dissipation efficiency of the heat sink 2. In some embodiments, the top shell 101 and the heat sink 2 can be formed by die casting, and the top shell 101 and the heat sink 2 can be made of aluminum, copper, copper-aluminum alloy, etc.
[0041] Example 2:
[0042] Based on Example 1, Example 2 has the following implementation method for the second drainage channel 4: Figure 4 As shown in Figure 6, a water inlet pipe 4a is provided on the outer side of the baffle plate 3. The second drainage channel 4 is located inside the water inlet pipe 4a and communicates with the first drainage channel 23. The baffle plate 3 has a communication port communicating with the second drainage channel 4. The inlet 41 of the second drainage channel 4 is close to the bottom of the first drainage channel 23. Furthermore, the water inlet pipe 4a extends outward toward the outside of the lamp box 1, so that the outlet 42 of the second drainage channel 4 extends outward to the outside of the lamp box 1, so that the outlet 42 of the second drainage channel 4 is far away from the lamp box 1, thereby preventing water from splashing onto the lamp box 1 when it flows out from the outlet 42 of the second drainage channel 4, and further protecting the explosion-proof lamp.
[0043] Optionally, the water pipe 4a is integrally formed with the radiator 2.
[0044] Optionally, the water pipe 4a is made of the same material as the radiator 2, so that the water pipe 4a can increase the heat dissipation area on the basis of drainage. Further, the water pipe 4a can be detachably connected to the baffle plate 3 by means of threaded connection or plug connection, and a sealing ring can be provided at the connection between the water pipe 4a and the baffle plate 3 to prevent water leakage.
[0045] Optionally, the water inlet pipe 4a may be made of a high-temperature resistant material and have a certain degree of flexibility to facilitate a tighter installation of the water inlet pipe 4a on the outside of the lamp box 1; on the other hand, an extension pipe may be provided on the outside of the water baffle 3, and the water inlet pipe 4a is sealed to the extension pipe.
[0046] Example 3:
[0047] Example 3, based on Example 2, describes the following implementation method for the water inlet pipe 4a: Figure 4 and Figure 6 As shown, any of the water inlet pipes 4a extends outward from the explosion-proof lamp along the length of the heat sink 21 to which it is connected, causing the outlet 42 of the second drainage channel 4 to extend away from the explosion-proof lamp; furthermore, the outlet 42 of the second drainage channel 4 may extend through the side edge of the lamp box 1 or through the bottom of the lamp box 1. It should be noted that the outlet of the water inlet pipe 4a only needs to extend slightly beyond the side edge of the explosion-proof lamp, and does not need to extend too much.
[0048] Optionally, the water inlet pipe 4a can be configured as follows: Figure 4 The Z-shaped pipe fitting shown.
[0049] Optional, such as Figure 6 As shown, the water pipe 4a is arranged along the outer contour of the radiator 2 and the lamp box 1.
[0050] Optionally, the water inlet pipe 4a can be configured as follows: Figure 5 The L-shaped pipe shown allows the outlet 42 of the second drainage channel 4 to extend through the bottom of the light box 1. When the outlet 42 of the second drainage channel 4 extends through the bottom of the light box 1, it can improve the aesthetics of the explosion-proof light while protecting it, and prevent the water pipe 4a from poking passersby or getting caught on debris.
[0051] Example 4:
[0052] In Example 4, based on one or more of Examples 1-3, the second drainage channel 4 further has the following implementation method, such as... Figure 4As shown, the lamp housing 1 is provided with a flow guide 4b, and the second drainage channel 4 passes through the flow guide 4b and communicates with the first drainage channel 23. The outlet 42 of the second drainage channel 4 extends to the bottom of the lamp housing 1, so that the outlet 42 of the second drainage channel 4 is away from the lamp housing 1, thereby preventing water from splashing onto the lamp housing 1 when it flows out from the outlet 42 of the second drainage channel 4, further protecting the explosion-proof lamp. Preferably, the flow guide 4b and the first drainage channel 23 are arranged in a one-to-one correspondence.
[0053] Optionally, the flow guide 4b is integrally formed with the top shell 101 of the lamp box 1 to improve the sealing performance of the flow guide 4b, and the bottom shell 102 of the lamp box 1 is provided with a relief cavity that is adapted to the flow guide 4b.
[0054] Example 5:
[0055] Example 5, based on Example 4, describes the following implementation for the guide portion 4b: Figure 3 As shown, the flow guide 4b is connected to the inner wall of the lamp box 1, that is, each flow guide 4b is arranged at equal intervals along the inner wall of the lamp box 1. The lamp box 1 is also provided with a partition 11 located on one side of the flow guide 4b. The partition 11 separates the lighting element and other electrical components from each flow guide 4b to protect the electrical components in the lamp box 1 and ensure the normal use of the explosion-proof lamp.
[0056] Example 6:
[0057] Example 6 is based on one or more of Examples 1-5, and has the following implementation method, such as... Figure 4 As shown, Figure 4 In the diagram, dashed line S1 represents the horizontal plane, and dashed line S2 represents the extension line of the inclined bottom wall 24. The first drainage channel 23 is provided with an inclined bottom wall 24. Any of the inclined bottom walls 24 is inclined along the length extension direction of the heat sink 21. The inclined bottom wall 24 has a preset angle 241 relative to the horizontal plane. The baffle plate 3 is located at the lower end of the inclined bottom wall 24, and the inlet 41 of the second drainage channel 4 is close to the baffle plate 3. The water accumulated in the first drainage channel 23 is guided to the second drainage channel 4 through the inclined bottom wall 24 so that the water is quickly discharged from the heat sink 2. Furthermore, the baffle plate 3 is located on the front side in the direction of water flow, further enabling the water to be discharged in an orderly manner through the second drainage channel 4.
[0058] In addition, the baffle plate 3 is provided at the lower end of the first drainage channel 23, and the higher end of the first drainage channel 23 can be set as an open end to ensure airflow between the heat sinks 21, thereby maintaining the heat dissipation effect of the radiator 2. Further optionally, the baffle plate 3 can also be provided at the higher end of the first drainage channel 23 to prevent water from flowing out from the higher end of the first drainage channel 23 and to improve the efficiency of water discharge from the second drainage channel 4.
[0059] Optionally, the preset angle 241 of the inclined bottom wall 24 relative to the horizontal plane is set to 0 degrees to 5 degrees, and the preset angle 241 is greater than 0 degrees, so as to accelerate the drainage speed of accumulated water and maintain a certain heat dissipation airflow 7 between each heat sink 21.
[0060] Preferably, when actually installing the explosion-proof light, ensure that the lower end of the first drainage channel 23 is lower than the higher end of the first drainage channel 23, that is, as shown below. Figure 4 As shown, keeping the bottom end of the inclined bottom wall 24 lower than the top end of the inclined bottom wall 24 results in better drainage.
[0061] Example 7:
[0062] Example 7 is based on one or more of Examples 1-6, and has the following implementation method, such as... Figure 7 As shown, the heat sink 21 includes at least a first heat sink 211 and a second heat sink 212 disposed near both sides of the lamp box 1, and a plurality of intermediate heat sinks 213 disposed at equal intervals between the first heat sink 211 and the second heat sink 212. Each intermediate heat sink 213 has a through hole 2131 at its bottom that communicates with the first drainage channel 23. By providing the through hole 2131 at the bottom of each intermediate heat sink 213, any one of the through holes 2131 communicates with the first drainage channel 23 on both sides, so as to further accelerate the drainage efficiency of water accumulated in each first drainage channel 23, avoid water residue, further protect the radiator 2, and improve the heat dissipation effect of the radiator 2.
[0063] Furthermore, both the first-end heat sink 211 and the last-end heat sink 212 have a third drainage channel 5 on the side away from the baffle plate 3, which communicates with the first drainage channel 23, and the drain outlet 51 of the third drainage channel 5 extends to the outside of the lamp box 1. By setting the third drainage channel 5, the second drainage channel 4 and the third drainage channel 5 on different sides relative to the radiator 2 provide the radiator 2 with more drainage channels in different directions, further improving drainage efficiency. In addition, the drainage structure in the explosion-proof lamp also includes each of the through holes 2131 and the third drainage channel 5.
[0064] Optionally, the inlet 52 of the third drainage channel 5 and each of the through holes 2131 can be on the same straight line to facilitate the machining of each of the through holes 2131 and the inlet 52 of the third drainage channel 5 in the radiator 2.
[0065] Optionally, the specific structure of the third drainage channel 5 can be referred to the implementation of the water inlet pipe 4a in Embodiments 2 and 3.
[0066] Example 8:
[0067] Example 8 is based on one or more of Examples 1-7, and has the following implementation method, such as... Figure 8 and Figure 9 As shown, the explosion-proof lamp also includes a power supply box 6 disposed on the upper part of the heat sink 2. The power supply box 6 is used to install a power supply device, which is electrically connected to the lighting element inside the lamp box 1 to provide power. The bottom of the power supply box 6 is provided with a downwardly extending first connecting portion 61, and the top of the lamp box 1 is provided with a upwardly extending second connecting portion 12. The first connecting portion 61 and the second connecting portion 12 are correspondingly arranged. The heat sink 21 includes at least a first heat sink 213a, and the second connecting portion 12 is disposed in the first heat sink 213a and is connected by the first connecting portion 61 and the second connecting portion 12. The power supply box 6 is mounted on the upper part of the heat sink 2, and a heat dissipation air duct 7 is formed between the power supply box 6 and the heat sink 2. The heat dissipation air duct 7 is connected to each of the first drainage channels 23. By spaced apart from the heat sink 2, the heat dissipation air duct 7 is formed between the power supply box 6 and the heat sink 2, thereby promoting the heat dissipation of the power device inside the power supply box 6 and ensuring the normal use of the explosion-proof lamp. Moreover, the heat dissipation air duct 7 is connected to the gaps between each of the heat sink fins 21, so as to enhance the airflow between the power supply box 6 and the heat sink 2, thereby improving the heat dissipation efficiency. It should be noted that the first heat sink 213a can be one of the intermediate heat sink 213 in embodiment 8.
[0068] In this embodiment, the second connecting part 12 extends toward the power box 6 along the height direction of the first heat sink 213a, and there is a drainage gap L between the two sides of the second connecting part 12 and the opposite heat sink 21 that communicates with the first drainage channel 23, so as to avoid the second connecting part 12 blocking the corresponding first drainage channel 23 and ensuring the drainage efficiency of each first drainage channel 23.
[0069] Optionally, a plurality of first connecting portions 61 are provided, and each of the first connecting portions 61 at the bottom of the power supply box 6 is arranged in a rectangular pattern, and each of the first connecting portions 61 is arranged close to the outer periphery of the power supply box 6. The second connecting portion 12 is arranged corresponding to the first connecting portion 61, so as to increase the connection stability between the power supply box 6 and the heat sink 2.
[0070] Optionally, both the first connecting part 61 and the second connecting part 12 are provided with connecting holes, and the first connecting part 61 and the second connecting part 12 are detachably connected by additional fasteners to facilitate the quick disassembly, assembly, and maintenance of the explosion-proof lamp.
[0071] Example 9:

Figure 9 and Figure 10 As shown, each of the heat sinks 21 has a raised portion 22 at its top to increase the heat dissipation area of each heat sink 21 and improve heat dissipation efficiency. Furthermore, the raised portion 22 in the first heat sink 213a has a clearance opening 2141. The position of the clearance opening 2141 corresponds to the position of the second connecting portion 12. The second connecting portion 12 extends into the clearance opening 2141. The first connecting portion 61 can extend into the clearance opening 2141 and connect with the second connecting portion 12 accordingly, so as to facilitate the tight connection between the power box 6 and the heat sink 2 and improve the structural compactness of the explosion-proof lamp.
[0073] Optionally, both the first connecting part 61 and the second connecting part 12 are provided as connecting holes, and the inner diameter of the first connecting part 61 is adapted to the outer diameter of the second connecting part 12, or the inner diameter of the second connecting part 12 is adapted to the outer diameter of the first connecting part 61. The second connecting part 12 extends into the relief opening 2141 along the height direction. During assembly, the power box 6 can first be positioned and inserted into the second connecting part 12 through the first connecting part 61, and then the power box 6 can be fixedly connected to the heat sink 2 by screws, bolts and other fasteners, so as to facilitate the rapid assembly of the power box 6.
[0074] In this embodiment, the inner diameter of the clearance opening 2141 is equal to or slightly larger than the outer diameter of the first connecting part 61 or the second connecting part 12, thereby reducing the installation difficulty of the power supply box 6.
[0075] Example 10:
[0076] Example 10, based on Example 8 and / or Example 9, has the following implementation method, such as... Figure 10As shown, a lead pipe 8 for power supply lines is provided between the power supply box 6 and the lamp box 1. The lead pipe 8 is located on one side of the second connecting part 12. The heat sink 21 includes at least a second heat sink 213b, and the lead pipe 8 is disposed in the second heat sink 213b. Optionally, the lead pipe 8 includes a third connecting part 81 disposed at the bottom of the power supply box 6 and a fourth connecting part 82 disposed at the top of the lamp box 1. The third connecting part 81 extends toward the lamp box 1, and the fourth connecting part 82 extends toward the power supply box 6. The fourth connecting part 82 is disposed in the second heat sink 213b, and both the third connecting part 81 and the fourth connecting part 82 have internal cavities. During assembly, the third connecting part 81 and the fourth connecting part 82 are connected accordingly, and the internal cavities of the third connecting part 81 and the fourth connecting part 82 are connected to each other, so as to facilitate the lead pipe 8 to connect the inside of the power supply box 6 and the inside of the lamp box 1 and allow the power supply line to pass through.
