Description

Technical Field

[0001] The present invention relates to the technical field of lamps, and particularly to an energy-saving and efficient LED industrial and mining lamp. Background Art

[0002] In an industrial production environment, especially in production operation areas such as factories, mines, and warehouses, as a key lighting device, the performance stability and durability of industrial and mining lamps are crucial for ensuring the normal progress of production activities. To meet the lighting requirements in these areas, industrial and mining lamps usually need to be equipped with high-power electronic components to ensure sufficient brightness and lighting range. However, these high-power electronic components generate a large amount of heat during operation. If the heat is not dissipated in time, it may lead to a decline in the performance of the lamp or even damage.

[0003] In the prior art, to solve the heat dissipation problem of industrial and mining lamps, a method of installing heat dissipation fins on electronic devices is usually adopted. By increasing the heat dissipation area, the heat dissipation fins can effectively dissipate the heat generated by the electronic components into the air, thereby reducing the working temperature of the lamp. For industrial and mining lamps with high power, in order to further improve the heat dissipation effect, a fan is also added for forced heat dissipation.

[0004] However, in the actual use process, especially in an environment with a large amount of dust, the heat dissipation system of the prior art industrial and mining lamps faces some problems. Since a plurality of heat dissipation fins are usually provided and there are gaps between adjacent fins, these gaps are easily places where dust adheres. Over time, the accumulation of dust in the fin gaps will seriously affect the heat dissipation effect of the heat dissipation fins, resulting in a decline in the heat dissipation performance of the industrial and mining lamps. This will not only reduce the service life of the lamp but also increase energy consumption because the lamp needs to consume more energy to maintain the normal working temperature.

Detailed implementation manners

[0039] The technical solution of the present invention will be further described below with reference to the drawings.

[0040] Embodiment 1

[0041] An energy-saving and high-efficiency LED industrial and mining lamp, as Figures 1 - 16 shown, includes a top cover 1, a connecting strip 2, an installation platform, a condenser cover 4, a bulb 5 and an installation part 12; several connecting strips 2 are fixedly connected to the top cover 1, and the top cover 1 is provided with a hollow opening at the lower part; all the connecting strips 2 are commonly connected to an installation platform; the installation platform is connected to the bulb 5; the installation platform is connected to the condenser cover 4, and the bulb 5 is surrounded by the condenser cover 4; the top cover 1 is provided with the installation part 12;

[0042] It also includes a lifting cover 101, a cooling fan 6, a signal receiving component 11, a filter screen 13 and a driving component; a cooling fan 6 is arranged inside the top cover 1, and the cooling fan 6 is located at the top of the top cover 1; at least two driving components are arranged on the outer side surface of the top cover 1; all the driving components are commonly connected to a hollow lifting cover 101 with upper and lower openings, and the lifting cover 101 is located inside the top cover 1, and the upper part of the mounting table is located inside the lifting cover 101; the top cover 1 is fixedly connected with a plurality of filter screens 13 at the same horizontal position; each filter screen 13 penetrates through the top cover 1; and the working part of the cooling fan 6 is located below all the filter screens 13; the top cover 1 is connected with a signal receiving component 11, and all the driving components are electrically connected to the detector.

[0043] The mounting table includes a rotary connection ring 30, a connecting block 31, a bottom table 32, a hollow mounting bin 33, and heat dissipation fins 34; all the connecting bars 2 are commonly fixedly connected to a rotary connection ring 30; a plurality of connecting blocks 31 are arranged on the inner ring surface of the rotary connection ring 30; all the connecting blocks 31 are commonly fixedly connected to a bottom table 32, and there is a circulation gap 001 between the rotary connection ring 30 and the bottom table 32; the bottom table 32 is fixedly connected with a hollow mounting bin 33 with a lower opening, and the hollow mounting bin 33 penetrates through the bottom table 32; electrical components for controlling the operation of the control bulb 5 are installed inside the hollow mounting bin 33; the hollow mounting bin 33 is fixedly connected with a plurality of heat dissipation fins 34.

[0044] The driving component on the left part of the top cover 1 includes a housing 111, a telescopic rod 112, a connecting piece 113 and a connecting component; the housing 111 is fixedly connected to the outer ring surface of the top cover 1; the telescopic rod 112 is fixedly connected inside the housing 111, and the telescopic rod 112 is electrically connected to the signal receiving component 11; the telescopic part of the telescopic rod 112 is fixedly connected to the connecting piece 113; the connecting piece 113 is connected to the connecting component; the connecting component is connected to the lifting cover 101.

[0045] Before the device works, the staff first fix the device at a preset installation position by using the fixing device and the installation part 12, and then connect the device to the power supply and connect the signal receiving component 11 to an external dust detector for communication.

[0046] After that, according to the actual lighting requirements, the device is powered on, and thus the device starts to work. At this time, the bulb 5 starts to work for lighting. Since the bulb 5 generates heat, which causes the working efficiency of the device to decrease, the electrical components of the bulb 5 are arranged inside the hollow mounting bin 33. The heat generated when the electrical components work will be transferred to the heat dissipation fins 34 through the hollow mounting bin 33, and the heat dissipation fins 34 are arranged to dissipate the heat, thereby improving the working efficiency of the device.

[0047] Moreover, to further improve the heat dissipation efficiency of the heat sink 34, a cooling fan 6 is also provided in this device. When the bulb 5 starts to work, the cooling fan 6 starts to work synchronously. The cooling fan 6 blows out air flow, and the air flow blows towards the heat sink 34. Then the air flow flows away from the sides of several heat sinks 34. In this way, the heat sink 34 can better perform the heat dissipation work;

[0048] However, in the actual use process, especially in an environment with a large amount of dust, since multiple heat sinks 34 are usually provided and there are installation gaps between adjacent heat sinks 34, the installation gaps are very likely to become places where dust adheres. Over time, the accumulation of dust in the installation gaps will seriously affect the heat dissipation effect of the heat sink 34, resulting in a decline in the heat dissipation performance of the industrial and mining lamp. This will not only reduce the service life of the lamp but also increase energy consumption because the lamp needs to consume more energy to maintain the normal working temperature;

[0049] Therefore, this device is also provided with a driving component, a lifting cover 101 and a signal receiving component 11. When an external dust detector detects that the dust content in the air exceeds a preset value, the external dust detector sends a control signal to the signal receiving component 11. After receiving the signal, the signal receiving component 11 controls the telescopic rod 112 to start working. The telescopic part of the telescopic rod 112 expands, driving the connected connecting piece 113 to move downward. The connecting piece 113 drives the connecting component to move, and the connecting component drives the connected lifting cover 101 to move downward to a preset position until the bottom surface of the lifting cover 101 contacts the screwing ring 30 of the installation table. At this time, the top cover 1, the lifting cover 101 and the installation table form a circulation cavity, and there is a circulation gap 001 between the screwing ring 30 and the bottom table 32.

[0050] At this time, the air flow generated by the cooling fan 6, when flowing, will not flow away from the sides of several heat sinks 34 because of the blockage of the lifting cover 101, but will flow out through the circulation gap 001 and flow towards the inner side of the condenser cover 4.

[0051] At this time, the air flow forms an air curtain on the inner side of the condenser cover 4, and the air curtain blocks the dust in the air. In this way, it can greatly avoid the dust adhering to the inner side of the condenser cover 4 and affecting the light condensing function of the condenser cover 4. This greatly reduces the maintenance work frequency of this device in the later stage.

[0052] Afterwards, when the dust detector detects that the dust content in the air does not exceed the preset value, the signal receiving component 11 controls the telescopic rod 112 to reset, and then makes other expanded parts of this device reset;

[0053] And under the blockage of the lifting cover 101, the dust in the air is greatly blocked, so that the heat sink 34 will not be attached with too much dust. This indirectly improves the heat dissipation efficiency of this device and further reduces the burden of later maintenance work;

[0054] Further, in order to ensure the normal circulation of air in the circulation cavity formed by the top cover 1, the lifting cover 101 and the installation table, the top cover 1 is provided with a filter net 13, and the filter net 13 penetrates through the top cover 1.

[0055] Embodiment 2

[0056] On the basis of Embodiment 1, as Figures 3 - 10 shown,

[0057] It further includes a scraping strip 103; a plurality of scraping strips 103 are fixedly connected to the lifting cover 101, and the number and positions of the scraping strips 103 correspond to the number and positions of the radiating fins 34; each scraping strip 103 is provided with a scraping groove; the scraping groove of each scraping strip 103 is in contact with the upper part of the radiating fin 34 at the corresponding position.

[0058] The upper surface of the bottom table 32 is arranged as an inclined surface, and the inclined arrangement of the upper surface of the bottom table 32 enables the scraping objects on the upper surface of the bottom table 32 to be better discharged.

[0059] When the device works, because insects and other organisms have phototaxis, in actual work, the installation gaps between adjacent radiating fins 34 will get stuck with insect corpses, or insects will leave excrement on the radiating fins 34. These attachments such as insect corpses and excrement will stick to the radiating fins 34, thereby affecting the heat dissipation work of the plurality of radiating fins 34.

[0060] Therefore, the lifting cover 101 is provided with a plurality of scraping strips 103 corresponding to the number and positions of the radiating fins 34. When the telescopic part of the telescopic rod 112 expands and drives the lifting cover 101 to move downward, the lifting cover 101 drives the connected scraping strips 103 to move until the bottom surface of the lifting cover 101 contacts the rotary connection ring 30. During the movement of the scraping strips 103, the scraping grooves opened in each scraping strip 103 scrape the surface of the radiating fin 34 at the corresponding position. In this way, the attachments on the surface of the radiating fin 34 can be removed, so that the heat dissipation work of the radiating fin 34 will not be affected.

[0061] Moreover, although under the shielding of the lifting cover 101, a great deal of dust in the air is blocked, so that the radiating fins 34 will not be attached with too much dust, but when the lifting cover 101 is not unfolded, the radiating fins 34 will still be attached with a certain amount of dust, affecting the heat dissipation work of the radiating fins 34.

[0062] Therefore, during the movement of the scraping strips 103, the dust attached to the surface of the radiating fins 34 can also be completely scraped off. In this way, the radiating fins 34 can be kept completely clean, which not only greatly ensures the heat dissipation work efficiency of the radiating fins 34, but also makes it more convenient for the staff to maintain the device.

[0063] Further, the attachments and dust on the surface of the heat sink 34 are scraped off by the scraping strip 103 to form scrapings, which fall on the bottom platform 32. At this time, the bottom surface of the lifting cover 101 contacts the rotary connection ring 30. Meanwhile, the heat dissipation fan 6 is also working to generate an air current. Under the blowing of the air current, the scrapings will be blown from the upper surface of the bottom platform 32 towards the circulation gap 001, and then the scrapings are discharged through the circulation gap 001.

[0064] And in order for the scrapings to be better blown and discharged, as Figure 9 shown, the upper surface of the bottom platform 32 is arranged as an inclined surface. In this way, when the air current blows the scrapings to roll on the upper surface of the bottom platform 32, the scrapings can be more smoothly blown towards the circulation gap 001 and discharged.

[0065] Embodiment 3

[0066] On the basis of Embodiment 2, as Figures 4 - 16 shown,

[0067] It further includes a first limiting piece 105, a driving rod 61, a concave part 1002, and an extension part 1001; an extension part 1001 is arranged in the middle of the lifting cover 101; each connecting component is connected to the extension part 1001; a concave part 1002 is arranged in the upper part of the lifting cover 101; at least one first limiting piece 105 is arranged on the inner ring surface of the concave part 1002; the working part of the heat dissipation fan 6 is connected with a driving rod 61; there is a cleaning gap between each heat sink 34 and the bottom platform 32;

[0068] Among them, the connecting component on the left part of the top cover 1 includes a slider 115 and a connecting piece 114; the connecting piece 113 is fixedly connected with the connecting piece 114; the connecting piece 114 is fixedly connected with the slider 115, and the slider 115 is slidably connected with the extension part 1001.

[0069] It further includes a brush strip 104 and a second limiting piece 106; several brush strips 104 are arranged on the outer ring surface of the concave part 1002, and the length of each brush strip 104 is set so that it can pass through the corresponding filter net 13; each brush strip 104 is arranged obliquely; at least one second limiting piece 106 is fixedly connected to the lower part of the inner ring surface of the lifting cover 101.

[0070] It further includes a hollow deformation ring 202, a deformation part 2021, and a push rod 116; the upper part of the rotary connection ring 30 is fixedly connected with a hollow deformation ring 202, and the hollow deformation ring 202 is provided with a deformation part 2021; each connecting piece 113 is fixedly connected with a push rod 116 at the lower part, and each connecting piece 114 is elastically arranged.

[0071] It further includes a limit frame 201. The upper part of the rotary connection ring 30 is fixedly connected to the limit frame 201 through a plurality of fixed columns, and each fixed column is in contact with the outer side surface of the hollow deformation ring 202. The setting of the limit frame 201 can prevent the hollow deformation ring 202 from twisting and shifting when it is squeezed.

[0072] Although the scraping strip 103 can completely scrape off the dust attached to the surface of the heat sink 34 during the movement process, in actual work, dust will also adhere to the upper surface of the base 32 after the device has been working for a long time.

[0073] Therefore, the device is also provided with a driving rod 61 and a first limiting piece 105. As Figure 5 shown, the working part of the heat dissipation fan 6 is connected to the driving rod 61. When the heat dissipation fan 6 works, it drives the connected driving rod 61 to start rotating, facilitating subsequent work.

[0074] When the bottom surface of the lifting cover 101 contacts the rotary connection ring 30, the first limiting piece 105 moves to the Figure 12 position. At this time, the first limiting piece 105 contacts the driving rod 61. At this time, the driving rod 61 is rotating, and the driving rod 61 will drive the first limiting piece 105 to rotate around the center of the base 32. The first limiting piece 105 drives the connected lifting cover 101 to rotate.

[0075] Moreover, the lifting cover 101 is connected to the telescopic rod 112 through the slider 115, the connecting piece 114, and the connecting piece 113 in sequence, and the slider 115 is slidably connected to the extended part 1001 provided on the lifting cover 101. Therefore, the rotation of the lifting cover 101 is not restricted.

[0076] And at this time, the scraping strip 103 is located in the cleaning gap at the corresponding position. Therefore, when the driving rod 61 drives the lifting cover 101 to rotate through the first limiting piece 105, the lifting cover 101 can drive a plurality of connected scraping strips 103 to rotate. During the rotation process of the scraping strip 103, the upper surface of the base 32 is scraped, so that the dust attached to the upper surface of the base 32 can be removed, and the scraped dust will also be discharged along the flow-through gap 001 under the blowing of the heat dissipation fan 6.

[0077] Furthermore, since the dust scraped off by the scraping strip 103 during work and the dust scraped off from the upper surfaces of the heat sink 34 and the base 32 are all discharged from the flow-through gap 001, and the light collecting cover 4 is located below the flow-through gap 001.

[0078] When the lifting cover 101 contacts the rotary connection ring 30, the lifting cover 101 will block the air flow, and the air flow generated by the heat dissipation fan 6 will also flow out from the circulation gap 001, forming an air curtain on the inner side of the condenser cover 4. However, since the dust removed by scraping will mix into the air flow, a turbid air flow will be formed. When the turbid air flow forms an air curtain on the inner side of the condenser cover 4, it will cause secondary pollution to the inner side of the condenser cover 4 by the turbid air flow.

[0079] Therefore, as Figure 13 shown, the device is provided with a hollow deformation ring 202, a deformation part 2021 and a push rod 116. The upper part of the rotary connection ring 30 is fixedly connected with the hollow deformation ring 202. Therefore, when the lifting cover 101 moves downward to a preset position, it does not contact the rotary connection ring 30, but contacts the upper surface of the hollow deformation ring 202.

[0080] And as Figure 15 shown, when the lifting cover 101 contacts the hollow deformation ring 202, the telescopic part of the telescopic rod 112 further expands, driving the connecting piece 113 to move further downward. And because the connecting piece 114 is an elastic part, when the connecting piece 113 moves, it will stretch the connecting piece 114. And because the scraping strip 103 connected to the lifting cover 101 has already contacted the base 32 at this time, the lifting cover 101 cannot continue to move downward.

[0081] The further downward movement of the connecting piece 113 drives the connected push rod 116 to move. And at this time, the push rod 116 also contacts the hollow deformation ring 202. When the push rod 116 moves, it squeezes the hollow deformation ring 202. At this time, the air inside the hollow deformation ring 202 is squeezed and moves towards the deformation part 2021 of the hollow deformation ring 202 until the deformation part 2021 is in the Figure 15 bulging state, and at this time, the bulging deformation part 2021 contacts the side of the base 32, thereby realizing the blocking of the circulation gap 001.

[0082] And at this time, the lifting cover 101 no longer contacts the hollow deformation ring 202. At this time, the circulation cavity formed by the top cover 1, the lifting cover 101 and the mounting table is directly communicated with the outside. In this way, the dust removed from the heat sink 34 and the upper surface of the base 32 can be directly discharged to the outside under the action of the air flow.

[0083] Then after a preset time, the telescopic rod 112 continues to work, and the telescopic part of the telescopic rod 112 retracts to the Figure 13 position, so that the hollow deformation ring 202 is reset, and the lifting cover 101 contacts the hollow deformation ring 202 again, and the circulation gap 001 is no longer blocked. In this way, the air flow flowing out from the circulation gap 001 will no longer be mixed with the removed dust;

[0084] In this way, the problem that the dust scraped off will mix into the air flow, thus forming a turbid air flow, and when the turbid air flow forms an air curtain on the inner side of the condenser cover 4, it will cause secondary pollution to the inner side of the condenser cover 4 by the turbid air flow is avoided.

[0085] Furthermore, all external air enters from the filter net 13 into the circulation cavity formed by the top cover 1, the lifting cover 101 and the installation table. Under long-term operation, dust will accumulate on the filter net 13, which will cause the external air to not enter the circulation cavity in time, and then affect the operation of the cooling fan 6 to generate air flow. In this way, the heat dissipation fins 34 covered by the lifting cover 101 cannot be discharged in time.

[0086] Therefore, the device is also provided with a brush strip 104 and a second limiting piece 106. As Figure 6 shown, when the telescopic rod 112 is not working, the second limiting piece 106 is located above the driving rod 61.

[0087] The telescopic rod 112 performs intermittent and regular expansion work. The telescopic part of the telescopic rod 112 starts to move, driving the lifting cover 101 to move downward. The lifting cover 101 drives the connected second limiting piece 106 to move downward until the second limiting piece 106 contacts the driving rod 61. At this time, the driving rod 61 can drive the lifting cover 101 to rotate through the second limiting piece 106. When the lifting cover 101 rotates, several brush strips 104 connected to the concave part 1002 of the lifting cover 101 also start to rotate. In this way, the brush strips 104 can brush the filter net 13 during the rotation process. And as Figure 16 shown, the length of each brush strip 104 is set so that it can pass through the filter net 13 at the corresponding position, and each brush strip 104 is obliquely arranged. In this way, the dust attached to the filter net 13 can be poked out to the outside during the rotation process of the brush strips 104. After a preset time, the telescopic rod 112 can be reset.

[0088] In this way, the problem in the prior art that under long-term operation of the filter net 13, dust will accumulate on the filter net 13, which will cause the external air to not enter the circulation cavity in time, and then affect the operation of the cooling fan 6 to generate air flow, and in this way, the heat dissipation fins 34 covered by the lifting cover 101 cannot be discharged in time is avoided.
