Description

Technical Field

[0001] The present invention relates to the technical field of explosion-proof lamps, and specifically to an intelligent LED explosion-proof lamp with a personnel positioning function. Background Art

[0002] With the rapid development of industries such as petroleum, chemical engineering, and mining, lighting fixtures are used more and more widely in production, warehousing, and rescue, and there are more and more varieties. How to prevent accidental explosions of lighting fixtures in explosive gas hazardous areas has become a very important topic. Since lighting fixtures inevitably generate electric sparks or form hot surfaces during operation, once they encounter an explosive gas mixture at the production or rescue site, it will lead to explosion accidents, directly endangering the lives of citizens and the safety of national property; therefore, explosion-proof lamps are lamps used in hazardous areas where combustible gases and dust exist, which can prevent electric arcs, sparks, and high temperatures that may be generated inside the lamp from igniting combustible gases and dust in the surrounding environment, thereby meeting the explosion-proof requirements.

[0003] Traditional explosion-proof lamps only have the lighting function and cannot achieve functions such as UWB precise positioning and intelligent lighting control, thus reducing the economic benefits of the lighting lamps. Especially in the roadway environment of coal mines, when there are people working in the mine, whether it is the roadway or the working area, the explosion-proof lamp has to be in the lighting state all the time. Even when there is no one in the roadway, the explosion-proof lamp is still in the lighting state. This will cause the explosion-proof lamp to be illuminated for a long time, resulting in too high temperatures inside and around the explosion-proof lamp, and then it is extremely easy to cause disasters such as fires. Moreover, during the use of the explosion-proof lamp, especially when used in an environment with a large amount of dust such as coal mines, a layer of dust will adhere to the surface of the glass cover at the light source, affecting the use effect of the explosion-proof lamp.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides an intelligent LED explosion-proof lamp with a personnel positioning function, having the following beneficial effects:

[0019] 1. For the intelligent LED explosion-proof lamp with a personnel positioning function, the LED explosion-proof lamp normally provides bright light. When no one is working under the lamp, the LED explosion-proof lamp is in a low-position working state, that is, the telescopic driving mechanism drives the lamp housing to descend to a specified position. At this time, the water diversion component is disconnected from the water injection component, and the water storage cavity independently supplies water to the cooling and wetting component and the spraying component. When the temperature of the control board is too high, the temperature detection sensor senses the temperature and converts the temperature signal into an electrical signal and transmits it to the control board. The control board controls the drainage mechanism to discharge the water in the water storage cavity to the cooling and wetting component and the spraying component. Then, the cooling and wetting component wets the outer surface of the lamp housing to increase the heat dissipation effect of the outer surface of the lamp housing. At the same time, the spraying component sprays water to spray the surface of the lamp cover to increase the cooling effect of the surface of the lamp cover.

[0020] 2. For the intelligent LED explosion-proof lamp with a personnel positioning function, when the microwave sensor detects that someone is working under the lamp, the LED explosion-proof lamp is in a high-position working state. The controller controls the telescopic driving mechanism to drive the lamp housing to rise until the water diversion component is connected to the water injection component. At this time, since the water diversion component is connected to the fire water distribution network pipeline, under the action of water pressure, water is injected into the spraying component through the water diversion component and the water injection component. At this time, the amount of water sprayed by the spraying component is relatively large, and the cleaning component is used to clean the dust on the surface of the lamp cover to avoid excessive dust on the surface of the lamp cover affecting the people working under the lamp. Moreover, the rising of the LED explosion-proof lamp can also prevent the LED explosion-proof lamp from affecting the operation during the operation.

[0021] 3. For the intelligent LED explosion-proof lamp with a personnel positioning function, the temperature detection sensor arranged between the heat collecting plate and the control board monitors the temperature of the control board. When the LED explosion-proof lamp generates high temperature during long-term use, resulting in too high temperature of the control board, the temperature detection sensor converts the temperature signal into an electrical signal and transmits it to the control board. The control board then controls the drainage mechanism to cooperate with the cooling and wetting component and the spraying component to cool the whole LED explosion-proof lamp. The water flow passes through the heat collecting plate in the drainage mechanism to cool the control board. When the temperature of the control board drops to a certain level and the temperature detected by the temperature detection sensor is within the safe value, the control board controls the drainage mechanism to stop draining water. At this time, the cooling and wetting component and the spraying component stop the cooling work; when the temperature detection sensor senses the temperature, it converts the temperature signal into an electrical signal and transmits it to the control board. The control board controls the drainage mechanism to discharge the water in the water storage cavity to the cooling and wetting component and the spraying component. Then, the cooling and wetting component wets the outer surface of the lamp housing to increase the heat dissipation effect of the outer surface of the lamp housing. At the same time, the spraying component sprays water to spray the surface of the lamp cover to increase the cooling effect of the surface of the lamp cover.

[0022] 4. The intelligent LED explosion-proof lamp with personnel positioning function uses a soaking tube and a capillary tube to draw water from the water storage cavity to the soaking sheet above the heat sink by capillary action, making the heat sink wet, and taking away heat through evaporation to achieve cooling. Since the soaking tube is connected to the middle of the side of the water storage cavity, when the LED explosion-proof lamp is not used for a long time, after the water in the water storage cavity drops below a certain level, the cooling and soaking component will lose the water source, preventing the situation that even when the LED explosion-proof lamp is not used for a long time, the water in the water storage cavity is continuously discharged through the cooling and soaking component, resulting in the inability of the water storage cavity to provide water for cooling when the LED explosion-proof lamp is used later.

[0023] 5. The intelligent LED explosion-proof lamp with personnel positioning function has a spraying water guiding pipe directly connected to the bottom end of the water injection part. When the telescopic driving mechanism drives the lamp housing to rise until the water guiding component is connected to the water injection part, the water in the fire sprinkler network pipeline can be directly injected into the spraying component through the spraying water guiding pipe. The injected water flows to the water distribution pipe, part of which is sprayed out through the capillary spraying nozzles on the periphery of the water distribution pipe, and part flows through the water distribution pipe to the return pipeline and is stored in the water storage cavity. At the same time, a transmission gear is arranged on one side of the driving gear ring. When the telescopic driving mechanism drives the lamp housing to rise until the water guiding component is connected to the water injection part, the lamp housing moves towards the mounting plate direction, and the transmission gear rolls on the straight rack, thereby driving the driving gear ring on the other side of the transmission gear to rotate. The driving gear ring drives the cleaning scraping rope at its bottom to rotate around the lamp shade, and then, driven by the linkage mechanism, the cleaning scraping rope rotates around the lamp shade with the rotating shaft at the other end of the cleaning scraping rope as the fulcrum. When rotating, the water sprayed out by the spraying component is scraped off, thereby completing the cleaning of the lamp shade and preventing excessive dust on the lamp shade from affecting the lighting effect of the LED explosion-proof lamp.

The water injection part 11 is arranged opposite to the water diversion component 3. The installation plate 2 and the lamp housing 1 are connected through a telescopic driving mechanism; A water storage cavity 4 is arranged above the inner cavity of the lamp housing 1. A drainage mechanism is arranged inside the water storage cavity 4; A cooling and infiltration component 5 is arranged on the outer side of the bottom of the water storage cavity 4. The cooling and infiltration component 5 is connected to the water storage cavity 4. A lamp cover 6 is arranged below the lamp housing 1. A spraying component 7 is arranged on the periphery of the lamp cover 6. One end of the spraying component 7 is communicated with the water diversion component 3 through the water injection part 11. The other end of the spraying component 7 is communicated with the water storage cavity 4 through a return pipeline 41; The telescopic driving mechanism drives the lamp housing 1 to move towards the installation plate 2. The water injection part 11 rises with the lamp housing 1 and is connected to the water diversion component 3. The water diversion component 3 injects water to one side of the spraying component 7 through the water injection part 11. When the water flow passes through the spraying component 7, the water is sprayed on the outer surface of the lamp cover 6. At the same time, the water flow flows into the water storage cavity 4 from the other side of the spraying component 7; A cleaning part 8 is arranged on the periphery of the lamp cover 6. A linkage mechanism is arranged on one side of the cleaning part 8 and is connected to the installation plate 2; A control board 12 is arranged inside the lamp housing 1. A positioning device is installed on the control board 12. The positioning device is electrically connected to the control board 12. A heat collecting plate 13 is arranged above the control board 12. A temperature detection sensor 14 is arranged between the heat collecting plate 13 and the control board 12. The temperature detection sensor 14 is electrically connected to the control board 12.

[0035] Before use, this LED explosion-proof lamp needs to be installed beside the fire sprinkler network pipeline through the installation plate 2 and connected to the fire pipeline through the water diversion component 3. This LED explosion-proof lamp is installed on the top of the use place through the installation plate 2; Among them, the telescopic driving mechanism is preferably an electric telescopic rod, and the positioning device adopts the existing UWB technology. The positioning label carrying UWB (not shown in the figure) communicates with the positioning and lighting control base station installed on the explosion-proof lamp. The fluctuation induction device is preferably an existing microwave sensor (not shown in the figure), which is used to detect whether there is someone working under the lamp; During installation and use, a sealing enclosure is arranged around the telescopic driving mechanism to isolate the electric telescopic rod. The control board 12 includes automation components such as a PLC controller. By programming the PLC controller in advance, the start of the telescopic driving mechanism, the opening of the LED explosion-proof lamp, the signal transmission of the temperature detection sensor 14, etc. are processed; Guide rods can also be arranged below the installation plate 2 and connected to the lamp housing 1 to avoid excessive shaking of the LED explosion-proof lamp when moving up and down; The fire sprinkler network pipe is an indoor fire sprinkler pipeline;

[0036] During use, this LED explosion-proof lamp normally provides bright light. When there is no one working under the lamp, the LED explosion-proof lamp is in a low-position working state, that is, the telescopic drive mechanism drives the lamp housing 1 to descend to a specified position. At this time, the water diversion assembly 3 is disconnected from the water injection part 11, and the water storage cavity 4 supplies water to the cooling and wetting assembly 5 and the spraying assembly 7 alone. When the temperature of the control board 12 is too high, the temperature detection sensor 14 senses the temperature and converts the temperature signal into an electrical signal and transmits it to the control board 12. The control board 12 controls the drainage mechanism to discharge the water in the water storage cavity 4 to the cooling and wetting assembly 5 and the spraying assembly 7. Then, the cooling and wetting assembly 5 wets the outer surface of the lamp housing 1 to increase the heat dissipation effect of the outer surface of the lamp housing 1. At the same time, the spraying assembly 7 sprays water to spray the surface of the lamp cover 6 to increase the cooling effect of the surface of the lamp cover 6;

[0037] When someone is working under the lamp, the microwave sensor (not shown in the figure) detects that someone is working under the lamp, and the LED explosion-proof lamp is in a high-position working state. The controller controls the telescopic drive mechanism to drive the lamp housing 1 to rise until the water diversion assembly 3 is connected to the water injection part 11. At this time, since the water diversion assembly 3 is connected to the fire sprinkler network pipeline, under the action of water pressure, water is injected into the spraying assembly 7 through the water diversion assembly 3 and the water injection part 11. At this time, the amount of water sprayed by the spraying assembly 7 is relatively large, and the cleaning part 8 is used to clean the dust on the surface of the lamp cover 6 to avoid the influence on the people working under the lamp caused by too much dust on the surface of the lamp cover 6. Moreover, the rising of the LED explosion-proof lamp can also prevent the LED explosion-proof lamp from affecting the operation during operation.

[0038] Furthermore, an LED lamp is provided at the bottom of the lamp housing 1, the control board 12 is located above the LED lamp, the heat collecting plate 13 is closely arranged with the control board 12, the middle part of the heat collecting plate 13 is in a hollow state, one side of the heat collecting plate 13 is communicated with the return pipeline 41, and the other end of the heat collecting plate 13 is connected to the spraying assembly 7; the temperature detection sensor 14 arranged between the heat collecting plate 13 and the control board 12 monitors the temperature of the control board 12. When the LED explosion-proof lamp generates high temperature during long-term use and causes the temperature of the control board 12 to be too high, the temperature detection sensor 14 converts the temperature signal into an electrical signal and transmits it to the control board 12. The control board 12 then controls the drainage mechanism to cooperate with the cooling and wetting assembly 5 and the spraying assembly 7 to cool the whole LED explosion-proof lamp. During the drainage process, the water flow passes through the heat collecting plate 13 to cool the control board 12. When the temperature of the control board 12 drops to a certain level (lower than the preset safe temperature) and the temperature detected by the temperature detection sensor 14 is within the safe value, the control board 12 controls the drainage mechanism to stop draining, and at this time, the cooling and wetting assembly 5 and the spraying assembly 7 stop the cooling work.

[0039] Further, the water diversion assembly 3 includes a U-shaped pipe 31. One end of the U-shaped pipe 31 is provided with a folded-back pipe 32. The bottom of the folded-back pipe 32 is provided with a water diversion thin pipe 33. The inner bottom end of the folded-back pipe 32 is provided with a trigger valve 34. The trigger valve 34 controls the communication between the water diversion thin pipe 33 and the folded-back pipe 32. During use, a filter element is provided on one side of the bottom of the U-shaped pipe 31, which can filter the water in the fire sprinkler network pipeline, so that impurities are concentrated in the U-shaped pipe 31. And when the filter element is used for a long time, the U-shaped pipe 31 can also be disassembled from the folded-back pipe 32 and a new U-shaped pipe 31 can be replaced. When the trigger valve 34 is closed, the water in the water diversion thin pipe 33 is discharged, and air exists in the water diversion thin pipe 33. When the next LED explosion-proof lamp rises to the position where the water diversion assembly 3 is communicated with the water injection part 11, at first, the water will be injected into the spraying assembly 7 mixed with some air, so that the high pressure generated by the water and the air is convenient for cleaning the lamp cover 6.

[0040] Further, the trigger valve 34 includes a support convex block 341. The support convex block 341 is arranged at the inner cavity bottom of the folded-back pipe 32. A tension spring 342 is arranged above the support convex block 341. An activity plug 343 is arranged inside the tension spring 342. The top of the activity plug 343 is connected to the other end of the tension spring 342. When the tension spring 342 is in a relaxed state, the activity plug 343 blocks the upper part of the water diversion thin pipe 33. The tension spring 342 above the support convex block 341 tightens the activity plug 343 and blocks the upper part of the water diversion thin pipe 33, so as to prevent the water in the fire sprinkler network pipeline from flowing out of the water diversion thin pipe 33 when the LED explosion-proof lamp descends to the position where the water diversion assembly 3 is disconnected from the water injection part 11.

[0041] Further, the water injection part 11 includes a water injection pipe 111. A V-shaped rubber ring 112 is arranged above the inner cavity of the water injection pipe 111. The opening of the V-shaped rubber ring 112 is downward. A support rod 113 is arranged at the inner cavity bottom of the water injection pipe 111. A thin rod 114 is arranged above the support rod 113. When the folded-back pipe 32 is connected to the water injection pipe 111, the thin rod 114 extends into the water diversion thin pipe 33 and pushes the activity plug 343 to move away from the water diversion thin pipe 33 upward. Through the thin rod 114 arranged in the water injection pipe 111, when the LED explosion-proof lamp rises to the position where the water diversion assembly 3 is communicated with the water injection part 11, the thin rod 114 extends into the water diversion thin pipe 33 and pushes the activity plug 343 at the top of the water diversion thin pipe 33 upward, so that the water diversion thin pipe 33 is communicated with the folded-back pipe 32, and then the water can be injected into the spraying assembly 7 in cooperation with the water injection pipe 111. When the water diversion thin pipe 33 is inserted into the water injection pipe 111, the V-shaped rubber ring 112 seals the top of the water injection pipe 111 between the two of them to prevent the water from flowing out from above the water injection pipe 111.

[0042] Further, the drainage mechanism includes a push rod 42. The push rod 42 is located below the water storage chamber 4. A push plate 43 is provided at the output end of the push rod 42. A one-way air vent 44 is provided on the water storage chamber 4. An installation flat plate 45 is provided at the tail of the output end of the push rod 42. The output end of the push rod 42 penetrates and slides on the installation flat plate 45. The push rod 42 is electrically connected to the control board 12. The push plate 43 moves towards the installation flat plate 45 driven by the push rod 42, and external air enters the water storage chamber 4 through the one-way air vent 44. Through the push rod 42 above the water storage chamber 4, when the temperature detection sensor 14 detects that the temperature of the control board 12 is too high, the control board 12 controls the push rod 42 to push the push plate 43 to squeeze the water storage chamber 4. At this time, the one-way air vent 44 is closed, and the air in the water storage chamber 4 cannot be discharged, so that the water in the water storage chamber 4 is discharged outwards. When the telescopic drive mechanism drives the lamp housing 1 to rise until the water diversion component 3 is communicated with the water injection part 11, the control board 12 controls the push rod 42 to drive the push plate 43 to move upwards. During the upward movement, due to the one-way air vent 44 provided above the water storage chamber 4, external air can enter the water storage chamber 4, avoiding a small change in the pressure in the water storage chamber 4 and directly sucking the water in the spraying component 7 into the water storage chamber 4, which affects the use of the spraying component 7.

[0043] Further, the cooling and wetting component 5 includes a wetting tube 51. The wetting tube 51 is communicated with the middle part of the side surface of the water storage chamber 4. A capillary tube 52 is provided at the bottom of the wetting tube 51. A heat sink 53 is provided below the capillary tube 52. A wetting sheet 54 is provided on the upper surface of the heat sink 53. The wetting sheet 54 is connected to the capillary tube 52. The water in the water storage chamber 4 is led to the wetting sheet 54 above the heat sink 53 in a capillary action manner through the cooperation of the wetting tube 51 and the capillary tube 52, so that the heat sink 53 can be wetted and the heat can be taken away by evaporation to achieve cooling. Since the wetting tube 51 is connected to the middle part of the side surface of the water storage chamber 4, when the LED explosion-proof lamp is not used for a long time, after the water in the water storage chamber 4 is lower than a certain level, the cooling and wetting component 5 will lose the water source, avoiding the situation that even when the LED explosion-proof lamp is not used for a long time, the water in the water storage chamber 4 is continuously discharged through the cooling and wetting component 5, resulting in the inability of the water storage chamber 4 to provide water for cooling when the LED explosion-proof lamp is used later.

[0044] Further, the spraying assembly 7 includes a spraying water guiding pipe 71, the spraying water guiding pipe 71 is connected to the bottom end of the water injection member 11, the bottom of the spraying water guiding pipe 71 penetrates through the lamp housing 1 and is provided with a water distribution pipe 73, the water distribution pipe 73 surrounds the outer side of the top end of the lamp cover 6 and is in close contact with the lamp cover 6, the return pipeline 41 is communicated with the water distribution pipe 73, the other end of the return pipeline 41 is communicated with the water storage cavity 4, a protective net 74 is arranged at the bottom of the water distribution pipe 73, the protective net 74 is arranged around the lamp cover 6, and a capillary water spraying port is arranged on the side of the water distribution pipe 73 facing the lamp cover 6; by directly connecting the spraying water guiding pipe 71 to the bottom end of the water injection member 11, when the telescopic driving mechanism drives the lamp housing 1 to rise until the water diversion assembly 3 is communicated with the water injection member 11, the water in the fire fighting water distribution network pipeline can be directly injected into the spraying assembly 7 through the spraying water guiding pipe 71, and the injected water flows to the water distribution pipe 73, a part of which is sprayed out from the capillary water spraying ports on the periphery of the water distribution pipe 73, and a part of which flows through the water distribution pipe 73 to the return pipeline 41 and flows into the water storage cavity 4 for storage.

[0045] Further, the cleaning member 8 includes a plurality of cleaning scraping ropes 81, the cleaning scraping ropes 81 are closely attached to the lamp cover 6, a rotating shaft 61 is arranged in the middle of the bottom end of the lamp cover 6, the rotating shaft 61 penetrates through the lamp cover 6, the bottom of the cleaning scraping ropes 81 is connected to the rotating shaft 61, and the top end of the cleaning scraping ropes 81 is connected to the linkage mechanism; by driving the cleaning scraping ropes 81 under the linkage mechanism, taking the rotating shaft 61 at the other end of the cleaning scraping ropes 81 as a fulcrum, the cleaning scraping ropes 81 rotate around the lamp cover 6, and when rotating, the water sprayed by the spraying assembly 7 is scraped off, thereby completing the cleaning of the lamp cover 6 and preventing too much dust on the lamp cover 6 from affecting the lighting effect of the LED explosion-proof lamp.

[0046] Further, the linkage mechanism includes a driving gear ring 82, the driving gear ring 82 is installed at the bottom of the lamp housing 1 and is located on the peripheral side above the lamp cover 6, the top of the cleaning scraping ropes 81 is connected to the lower surface of the driving gear ring 82, the tooth surface of the driving gear ring 82 faces upward, a transmission gear 83 is arranged on one side of the driving gear ring 82, one end of the transmission gear 83 is meshed with the driving gear ring 82, and a straight rack 84 is meshed with the other end of the transmission gear 83, and the straight rack 84 is connected to the mounting plate 2; through the transmission gear 83 arranged on one side of the driving gear ring 82, when the telescopic driving mechanism drives the lamp housing 1 to rise until the water diversion assembly 3 is communicated with the water injection member 11, the lamp housing 1 moves towards the mounting plate 2, the transmission gear 83 rolls on the straight rack 84, thereby driving the driving gear ring 82 on the other side of the transmission gear 83 to rotate, and the driving gear ring 82 drives the cleaning scraping ropes 81 at its bottom to rotate around the lamp cover 6.

[0047] Working principle: Before use, this LED explosion-proof lamp needs to be installed beside the fire fighting water distribution network pipeline through the mounting plate 2 and connected to the fire fighting pipeline through the water diversion assembly 3, and this LED explosion-proof lamp is installed at the top of the use place through the mounting plate 2;

[0048] During use, this LED explosion-proof lamp normally provides bright light. When there is no one working under the lamp, the LED explosion-proof lamp is in a low-position working state, that is, the telescopic drive mechanism drives the lamp housing 1 to descend to a specified position. At this time, the water diversion component 3 is disconnected from the water injection part 11, and the water storage cavity 4 independently supplies water to the cooling and infiltration component 5 and the spraying component 7. The temperature detection sensor 14 arranged between the heat collecting plate 13 and the control board 12 monitors the temperature of the control board 12. When the LED explosion-proof lamp generates high temperature during long-term use, resulting in too high a temperature of the control board 12, the temperature detection sensor 14 converts the temperature signal into an electrical signal and transmits it to the control board 12. The control board 12 then controls the drainage mechanism to cooperate with the cooling and infiltration component 5 and the spraying component 7 to cool the entire LED explosion-proof lamp. During the drainage process, the water flows through the heat collecting plate 13 to cool the control board 12. When the temperature of the control board 12 drops to a certain level (lower than the preset safe temperature), and the temperature detected by the temperature detection sensor 14 is within the safe value, the control board 12 controls the drainage mechanism to stop draining. At this time, the cooling and infiltration component 5 and the spraying component 7 stop the cooling work; when the temperature detection sensor 14 senses the temperature, it converts the temperature signal into an electrical signal and transmits it to the control board 12. The control board 12 controls the drainage mechanism to discharge the water in the water storage cavity 4 to the cooling and infiltration component 5 and the spraying component 7. Then, the cooling and infiltration component 5 wets the outer surface of the lamp housing 1 to increase the heat dissipation effect of the outer surface of the lamp housing 1. At the same time, the spraying component 7 sprays water to the surface of the lamp cover 6 to increase the cooling effect of the surface of the lamp cover 6;

[0049] In the above process, through the push rod 42 above the water storage cavity 4, when the temperature detection sensor 14 detects that the temperature of the control board 12 is too high, the control board 12 controls the push rod 42 to push the push plate 43 to squeeze the water storage cavity 4. At this time, the one-way ventilation hole 44 is closed, and the air in the water storage cavity 4 cannot be discharged, so that the water in the water storage cavity 4 is discharged outward; when the telescopic drive mechanism drives the lamp housing 1 to rise until the water diversion component 3 is connected to the water injection part 11, the control board 12 controls the push rod 42 to drive the push plate 43 to move upward. During the upward movement, due to the one-way ventilation hole 44 arranged above the water storage cavity 4, external air can enter the water storage cavity 4, avoiding a small change in the pressure in the water storage cavity 4 and directly sucking the water in the spraying component 7 into the water storage cavity 4, which affects the use of the spraying component 7;

[0050] Among them, when the cooling and wetting component 5 wets the outer surface of the lamp housing 1, the water in the water storage chamber 4 is led to the wetting piece 54 above the heat sink 53 in a capillary action manner through the wetting pipe 51 and the capillary 52, so that the heat sink 53 can be wetted, and heat is taken away by evaporation to achieve cooling. Since the wetting pipe 51 is connected to the middle of the side of the water storage chamber 4, when the LED explosion-proof lamp is not used for a long time, after the water in the water storage chamber 4 drops below a certain level, the cooling and wetting component 5 will lose the water source, avoiding the situation that even when the LED explosion-proof lamp is not used for a long time, the water in the water storage chamber 4 is continuously discharged through the cooling and wetting component 5, resulting in the inability of the water storage chamber 4 to provide water for cooling when the LED explosion-proof lamp is used later;

[0051] When someone is working under the lamp, the LED explosion-proof lamp is in a high-position working state, that is, the telescopic driving mechanism drives the lamp housing 1 to rise until the water diversion component 3 is connected to the water injection part 11. At this time, since the water diversion component 3 is connected to the fire sprinkler network pipeline, under the action of water pressure, water is injected into the spraying component 7 through the water diversion component 3 and the water injection part 11. At this time, the amount of water sprayed by the spraying component 7 is relatively large, and the cleaning part 8 is used to clean the dust on the surface of the lamp cover 6, avoiding the influence on the people working under the lamp caused by too much dust on the surface of the lamp cover 6. Moreover, the rising of the LED explosion-proof lamp can also prevent the LED explosion-proof lamp from affecting the operation during the operation;

[0052] Among them, a filter element is arranged on one side of the bottom of the U-shaped pipe 31, which can filter the water in the fire sprinkler network pipeline, so that impurities are concentrated in the U-shaped pipe 31. When the filter element is used for a long time, the U-shaped pipe 31 can also be disassembled between the U-shaped pipe 31 and the folded-back pipe 32 and a new U-shaped pipe 31 can be replaced; when the trigger valve 34 is closed, the water in the water diversion thin pipe 33 is discharged, and there is air in the water diversion thin pipe 33. When the LED explosion-proof lamp rises again until the water diversion component 3 is connected to the water injection part 11, at first, the water will be injected into the spraying component 7 mixed with part of the air, so that the high pressure generated by the water and the air is used to facilitate the cleaning of the lamp cover 6;

[0053] When the LED explosion-proof lamp rises to the point where the water diversion component 3 is connected to the water injection component 11, through the thin rod 114 provided in the water injection pipe 111, when the LED explosion-proof lamp rises to the point where the water diversion component 3 is connected to the water injection component 11, the thin rod 114 extends into the water diversion thin pipe 33 and pushes the movable plug 343 at the top of the water diversion thin pipe 33 upward, enabling communication between the water diversion thin pipe 33 and the folded-back pipe 32. Furthermore, it can cooperate with the water injection pipe 111 to inject water into the spraying component 7. Among them, when the V-shaped rubber ring 112 inserts the water diversion thin pipe 33 into the water injection pipe 111, the space between them seals the top of the water injection pipe 111 to prevent water from flowing out above the water injection pipe 111. The movable plug 343 is tightened by the tension spring 342 above the support bump 341, and the upper part of the water diversion thin pipe 33 is blocked. When the LED explosion-proof lamp descends to the point where the water diversion component 3 is disconnected from the water injection component 11, the water in the fire sprinkler network pipeline will not flow out from the water diversion thin pipe 33.

[0054] During the process of the above-mentioned LED explosion-proof lamp rising to the point where the water diversion component 3 is connected to the water injection component 11, the spraying water diversion pipe 71 is directly connected to the bottom end of the water injection component 11. When the telescopic drive mechanism drives the lamp housing 1 to rise to the point where the water diversion component 3 is connected to the water injection component 11, the water in the fire sprinkler network pipeline can directly be injected into the spraying component 7 through the spraying water diversion pipe 71. The injected water flows to the water distribution pipe 73. Part of the water sprays out from the capillary water spray openings on the circumferential side of the water distribution pipe 73, and part of the water flows through the water distribution pipe 73 to the return pipeline 41 and flows into the water storage cavity 4 for storage. At the same time, on one side of the driving gear ring 82, there is a transmission gear 83. When the telescopic drive mechanism drives the lamp housing 1 to rise to the point where the water diversion component 3 is connected to the water injection component 11, the lamp housing 1 moves towards the mounting plate 2. The transmission gear 83 rolls on the straight rack 84, thereby driving the driving gear ring 82 on the other side of the transmission gear 83 to rotate. The driving gear ring 82 drives the cleaning scraping rope 81 at its bottom to rotate around the lamp cover 6. Furthermore, driven by the linkage mechanism, the cleaning scraping rope 81 rotates around the lamp cover 6 with the rotating shaft 61 at the other end of the cleaning scraping rope 81 as the fulcrum. When rotating, the water sprayed by the spraying component 7 is scraped off, thereby completing the cleaning of the lamp cover 6 and preventing excessive dust on the lamp cover 6 from affecting the lighting effect of the LED explosion-proof lamp.
