Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lamps, in particular to an energy-saving and efficient LED mining lamp. BACKGROUND

[0002] In industrial production environments, especially in production operation areas such as factories, mines and warehouses, mining lamps as key lighting equipment, their performance stability and durability are crucial to ensure the normal operation of production activities. In order to meet the lighting needs of these areas, 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 will generate a large amount of heat during operation, which may cause the performance of the lamp to decline or even be damaged if not cooled in time.

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

[0004] However, in actual use, especially in environments with a lot of dust, the existing mining lamp heat dissipation system faces some problems. Since the heat dissipation fins are usually arranged in multiple and there are gaps between adjacent fins, these gaps are easy to become a place for dust to adhere. With the passage of time, the accumulation of dust in the fin gaps will seriously affect the heat dissipation effect of the heat dissipation fins, leading to a decline in the heat dissipation performance of the mining lamp. This not only reduces the service life of the lamp, but also increases energy consumption, because the lamp needs to consume more energy to maintain a normal working temperature. SUMMARY

Detailed Implementation

[0038] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0039] Example 1

[0040] An energy-efficient LED industrial and mining lamp, such as Figures 1-16 As shown, it includes a top cover 1, connecting strips 2, a mounting platform, a condenser 4, a bulb 5, and a mounting part 12; the top cover 1 is fixedly connected to several connecting strips 2, and the top cover 1 is hollow with an opening at the bottom; all connecting strips 2 are connected to a mounting platform; the mounting platform is connected to the bulb 5; the mounting platform is connected to the condenser 4, and the bulb 5 is surrounded by the condenser 4; the top cover 1 is provided with a mounting part 12;

[0041] Also includes the lifting cover 101, heat dissipation fan 6, signal receiving assembly 11, filter screen 13 and drive assembly; the top cover 1 inside is provided with heat dissipation fan 6, and the heat dissipation fan 6 is located at the top of the top cover 1;The outer side of the top cover 1 is provided with at least two drive assemblies;All drive assemblies are jointly connected with a hollow lifting cover 101 with up and down openings, and the lifting cover 101 is located inside the top cover 1, and the upper part of the mounting table is located in 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 the top cover 1;And the working part of the heat dissipation fan 6 is located below all filter screens 13;The top cover 1 is connected with the signal receiving assembly 11, and all drive assemblies are electrically connected with the detector.

[0042] The mounting table comprises a threaded ring 30, a connecting block 31, a base 32, a hollow mounting bin 33, and a heat sink 34;All connecting strips 2 are jointly fixedly connected with a threaded ring 30;The inner ring surface of the threaded ring 30 is provided with a plurality of connecting blocks 31;All connecting blocks 31 are jointly fixedly connected with a base 32, and there is a flow gap 001 between the threaded ring 30 and the base 32;The base 32 is fixedly connected with a hollow mounting bin 33 with a lower opening, and the hollow mounting bin 33 penetrates the base 32;The hollow mounting bin 33 is installed with electrical components for controlling the operation of the bulb 5;The hollow mounting bin 33 is fixedly connected with a plurality of heat sinks 34.

[0043] The drive assembly on the left of the top cover 1 comprises a shell 111, a telescopic rod 112, a connecting piece 113 and a connecting component;The outer ring surface of the top cover 1 is fixedly connected with a shell 111;The telescopic rod 112 is fixedly connected in the shell 111, and the telescopic rod 112 is electrically connected with the signal receiving assembly 11;The telescopic rod 112 is fixedly connected with a connecting piece 113 at the telescopic part;The connecting piece 113 is connected with a connecting component;The connecting component is connected with the lifting cover 101.

[0044] Before the device works, the staff first fixes the device at the preset installation position by the fixing device using the mounting part 12, then connects the device with the power supply, and communicates and connects the signal receiving assembly 11 with the external dust detector;

[0045] Then, according to the actual lighting demand, the device is powered, so that the device starts to work, at this time the bulb 5 starts to work and performs lighting work, and because the bulb 5 will generate heat, which will reduce the working efficiency of the device, so the electrical components of the bulb 5 are arranged in the hollow mounting bin 33, and the heat generated by the electrical components during work will be transferred to the heat sink 34 through the hollow mounting bin 33, and the heat sink 34 is arranged to dissipate heat, thereby improving the working efficiency of the device,

[0046] And in order to further improve the heat dissipation efficiency of the heat dissipation fin 34, the device is also provided with a heat dissipation fan 6, which starts to work at the same time when the bulb 5 starts to work. The heat dissipation fan 6 blows out the air flow, which blows to the heat dissipation fin 34, and then the air flow flows away from the side of the heat dissipation fin 34. In this way, the heat dissipation fin 34 can better perform the heat dissipation work;

[0047] But in actual use, especially in the environment with more dust, because the heat dissipation fin 34 is usually provided with multiple heat dissipation fins, and there is an installation gap between adjacent heat dissipation fins 34, the installation gap is easy to become a place for dust to adhere. With the passage of time, the accumulation of dust in the installation gap will seriously affect the heat dissipation effect of the heat dissipation fin 34, resulting in the decline of the heat dissipation performance of the industrial and mining lamp. This not only reduces the service life of the lamp, but also increases the energy consumption, because the lamp needs to consume more energy to maintain the normal working temperature;

[0048] Therefore, the device is also provided with a driving assembly, a lifting cover 101 and a signal receiving assembly 11. When the external dust detector detects that the dust content in the air exceeds the preset value, the external dust detector sends a control signal to the signal receiving assembly 11. After receiving the signal, the signal receiving assembly 11 controls the telescopic rod 112 to start working. The telescopic part of the telescopic rod 112 expands, driving the connected connecting sheet 113 to move downward. The connecting sheet 113 drives the connected 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 with the screw ring 30 of the mounting table. At this time, the top cover 1, the lifting cover 101 and the mounting table form a flow cavity, and there is a flow gap 001 between the screw ring 30 and the bottom table 32,

[0049] At this time, the air flow generated by the heat dissipation fan 6 will not flow away from the side of the heat dissipation fin 34 when flowing because of the shielding of the lifting cover 101, but will flow out through the flow gap 001 and flow to the inner side surface of the light collector 4.

[0050] At this time, the air flow forms a wind curtain on the inner side surface of the light collector 4, which blocks the dust in the air. In this way, the dust adhering to the inner side surface of the light collector 4 can be greatly avoided, which greatly reduces the maintenance frequency of the device in the later period.

[0051] After the dust detector detects that the dust content in the air does not exceed the preset value, the signal receiving assembly 11 controls the telescopic rod 112 to reset, so that the other expanded parts of the device are reset.

[0052] And under the shielding of the lifting cover 101, the dust in the air is greatly blocked, so that the heat dissipation fin 34 will not be adhered by too much dust, which indirectly improves the heat dissipation efficiency of the device and further reduces the burden of the later maintenance work;

[0053] Further, in order to ensure that the top cover 1, the lifting cover 101 and the mounting table form the normal circulation of air in the circulation cavity, the top cover 1 is provided with a filter screen 13, and the filter screen 13 penetrates the top cover 1.

[0054] Embodiment 2

[0055] On the basis of embodiment 1, as shown in Figures 3-10 ,

[0056] Further, the device also includes a scraping strip 103; the lifting cover 101 is fixedly connected with a plurality of scraping strips 103, and the number and position of the scraping strips 103 correspond to the number and position of the heat dissipation fins 34; each scraping strip 103 is provided with a scraping groove; and the scraping groove of each scraping strip 103 is in contact with the upper part of the heat dissipation fin 34 at the corresponding position.

[0057] The upper surface of the bottom table 32 is provided as an inclined surface, and the inclined arrangement of the upper surface of the bottom table 32 enables the scraped material on the upper surface of the bottom table 32 to be better discharged.

[0058] During operation of the device, because insects and other organisms have phototaxis, in actual operation, the installation gap between adjacent heat dissipation fins 34 will be blocked by insect carcasses, or insects will leave excrement on the heat dissipation fins 34. These insect carcasses and excrement and other attachments will stick to the heat dissipation fins 34, thereby affecting the heat dissipation work of the heat dissipation fins 34,

[0059] Therefore, the lifting cover 101 is provided with a plurality of scraping strips 103 corresponding to the number and position of the heat dissipation fins 34. When the telescopic rod 112 is extended to drive 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 is in contact with the threaded ring 30. During the movement of the scraping strips 103, the scraping groove of each scraping strip 103 scrapes the surface of the heat dissipation fin 34 at the corresponding position, so that the attachments on the surface of the heat dissipation fin 34 can be removed, and the heat dissipation work of the heat dissipation fin 34 will not be affected,

[0060] Although the lifting cover 101 greatly blocks dust in the air, so that the heat dissipation fin 34 will not be attached by too much dust, but when the lifting cover 101 is not expanded, the heat dissipation fin 34 will still be attached by some dust, which will affect the heat dissipation work of the heat dissipation fin 34,

[0061] Therefore, the scraping strip 103 can also completely scrape off the dust attached to the surface of the heat dissipation fin 34 during the movement, so that the heat dissipation fin 34 can be kept completely clean, which not only greatly guarantees the heat dissipation work efficiency of the heat dissipation fin 34, but also makes it more convenient for the workers to maintain the device;

[0062] Further, the attachments and dust on the surface of the heat dissipation fins 34 are scraped off by the scraper 103 to form scrapings, which fall on the base 32. At this time, the bottom surface of the lifting cover 101 is in contact with the threaded ring 30, and the heat dissipation fan 6 is also working to generate airflow. Under the blowing of the airflow, the scrapings are blown from the upper surface of the base 32 to the flow-through gap 001, and then the scrapings are discharged through the flow-through gap 001,

[0063] In order to better blow and discharge the scrapings, as shown in Figure 9 the upper surface of the base 32 is provided as an inclined surface. In this way, when the scrapings are rolled on the upper surface of the base 32 under the blowing of the airflow, the scrapings can be more smoothly blown to the flow-through gap 001 and discharged.

[0064] Embodiment 3

[0065] Based on the embodiment 2, as shown in Figures 4-16

[0066] Further, the first limiting piece 105, the driving rod 61, the recess 1002, and the extension part 1001 are also included. The extension part 1001 is arranged at the middle part of the lifting cover 101. Each connecting component is connected with the extension part 1001. The recess 1002 is arranged at the upper part of the lifting cover 101. At least one first limiting piece 105 is arranged on the inner ring surface of the recess 1002. The driving rod 61 is connected with the working part of the heat dissipation fan 6. Each heat dissipation fin 34 has a cleaning gap with the base 32.

[0067] The connecting component of the left part of the top cover 1 includes the sliding block 115 and the connecting piece 114. The connecting piece 114 is fixedly connected with the sliding block 115, and the sliding block 115 is in sliding connection with the extension part 1001.

[0068] Further, the brush strip 104 and the second limiting piece 106 are also included. The outer ring surface of the recess 1002 is provided with a plurality of brush strips 104, and the length of each brush strip 104 is arranged to be able to pass through the corresponding position of the filter screen 13. Each brush strip 104 is arranged obliquely. At least one second limiting piece 106 is fixedly connected to the inner ring surface of the lifting cover 101.

[0069] Further, the hollow deformation ring 202, the deformation part 2021, and the pushing rod 116 are also included. The hollow deformation ring 202 is fixedly connected to the upper part of the threaded ring 30, and the hollow deformation ring 202 is provided with the deformation part 2021. One pushing rod 116 is fixedly connected to the lower part of each connecting piece 113, and each connecting piece 114 is elastically arranged.

[0070] ​Further comprising a limiting frame 201, the upper part of the threaded ring 30 is fixedly connected with the limiting frame 201 through a plurality of fixing columns, and each fixing column is in contact with the outer side of the hollow deformation ring 202. The limiting frame 201 can prevent the hollow deformation ring 202 from being twisted and deviated when being extruded.

[0071] Although the wiper strip 103 can completely remove the dust attached to the surface of the heat dissipation fin 34 during movement, in actual work, the upper surface of the base table 32 will also be attached with dust after long-term work of the device,

[0072] Therefore, the device is also provided with a driving rod 61 and a first limiting piece 105. As shown, the working part of the heat dissipation fan 6 is connected with the driving rod 61. When the heat dissipation fan 6 works, the connected driving rod 61 starts to rotate, which facilitates the subsequent work. Figure 5

[0073] When the bottom surface of the lifting cover 101 is in contact with the threaded ring 30, the first limiting piece 105 moves to the position, at which time the first limiting piece 105 is in contact with 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 table 32. The first limiting piece 105 drives the connected lifting cover 101 to rotate, Figure 12

[0074] The lifting cover 101 is connected with the telescopic rod 112 through the sliding block 115, the connecting piece 114 and the connecting piece 113 in turn, and the sliding block 115 is slidingly connected with the extension part 1001 of the lifting cover 101. Therefore, the rotation of the lifting cover 101 is not limited.

[0075] At this time, the wiper strip 103 is located in the corresponding cleaning gap. 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 the connected wiper strips 103 to rotate. The wiper strips 103 remove the dust on the upper surface of the base table 32 during rotation. In this way, the dust attached to the upper surface of the base table 32 can be removed, and the removed dust will also be discharged along the flow-through gap 001 under the blowing of the heat dissipation fan 6.

[0076] Further, the dust removed by the wiper strip 103 from the heat dissipation fin 34 and the upper surface of the base table 32 is discharged from the flow-through gap 001, and the light collector 4 is below the flow-through gap 001.

[0077] ​​And when the lifting cover 101 contacts the screw ring 30, the lifting cover 101 will block the air flow, and the air flow generated by the cooling fan 6 will also flow out from the flow gap 001, forming an air curtain on the inner side of the light cover 4. However, because the dust removed will mix into the air flow, the turbid air flow will cause secondary pollution to the inner side of the light cover 4 when forming the air curtain on the inner side of the light cover 4,

[0078] Therefore, as Figure 13 Indicated, the device is provided with a hollow deformation ring 202, a deformation part 2021 and a push rod 116. The upper part of the screw ring 30 is fixedly connected with the hollow deformation ring 202. Therefore, when the lifting cover 101 moves downward to the preset position, it is not in contact with the screw ring 30, but in contact with the upper surface of the hollow deformation ring 202,

[0079] And as Figure 15 Indicated, when the lifting cover 101 contacts the hollow deformation ring 202, the extension rod 112 further expands the extension part, driving the connecting sheet 113 to further move downward. Because the connecting piece 114 is an elastic piece, the connecting sheet 113 will stretch the connecting piece 114 when moving. Because the scraping strip 103 connected with the lifting cover 101 has contacted the bottom table 32 at this time, the lifting cover 101 cannot continue to move downward,

[0080] The further downward movement of the connecting sheet 113 drives the connected push rod 116 to move. At this time, the push rod 116 also contacts the hollow deformation ring 202. When the push rod 116 moves, it extrudes the hollow deformation ring 202. At this time, the air inside the hollow deformation ring 202 is extruded and moves toward the deformation part 2021 of the hollow deformation ring 202, until the deformation part 2021 is in a Figure 15 Swollen state, and at this time the swollen state deformation part 2021 contacts the side of the bottom table 32, thereby realizing the blocking of the flow gap 001,

[0081] At this time, the lifting cover 101 no longer contacts the hollow deformation ring 202. At this time, the top cover 1, the lifting cover 101 and the mounting table form a flow cavity which is directly communicated with the outside. Therefore, the dust removed on the surface of the cooling fin 34 and the bottom table 32 can be directly discharged to the outside under the action of the air flow,

[0082] Then after a preset time, the extension rod 112 continues to work, and the extension part of the extension rod 112 retracts to Figure 13 The position, so that the hollow deformation ring 202 resets, and the lifting cover 101 recontacts the hollow deformation ring 202. The flow gap 001 is no longer blocked. Therefore, the air flow flowing out from the flow gap 001 will no longer mix with the dust removed;

[0083] This avoids the problem of dust being mixed into the airflow during dust removal, which would create a turbid airflow. When the turbid airflow forms an air curtain on the inner side of the focusing cover 4, it would cause secondary pollution to the inner side of the focusing cover 4.

[0084] Furthermore, external air enters through the filter 13 into the circulation cavity formed by the top cover 1, the lifting shroud 101, and the mounting platform. Over long-term operation, dust accumulates on the filter 13, preventing external air from entering the circulation cavity in a timely manner. This, in turn, affects the airflow generated by the cooling fan 6, thus preventing the heat sink 34, covered by the lifting shroud 101, from being properly exhausted.

[0085] Therefore, this device is also equipped with a brush strip 104 and a second limiting piece 106, such as Figure 6 As shown, when the telescopic rod 112 is not in operation, the second limiting piece 106 is located above the drive rod 61.

[0086] The telescopic rod 112 performs intermittent, periodic deployment. The telescopic part of the telescopic rod 112 begins to move, causing the lifting cover 101 to move downwards. The lifting cover 101 then causes the connected second limiting plate 106 to move downwards until the second limiting plate 106 contacts the drive rod 61. At this point, the drive rod 61 can then drive the lifting cover 101 to rotate via the second limiting plate 106. When the lifting cover 101 rotates, several brush strips 104 connected to the recess 1002 of the lifting cover 101 also begin to rotate. Thus, the brush strips 104 can brush the filter screen 13 during rotation, and... Figure 16 Each brush bar 104 is designed to pass through the corresponding filter screen 13, and each brush bar 104 is angled. This allows the brush bar 104 to push dust adhering to the filter screen 13 outwards during rotation. After a preset time, the telescopic rod 112 returns to its original position.

[0087] This avoids the problem that in existing technology, dust accumulates on the filter screen 13 during long-term operation, which prevents external air from entering the circulation cavity in time. This, in turn, affects the operation of the cooling fan 6 and the airflow, thus preventing the heat sink 34 covered by the lifting cover 101 from being discharged in time.

[0088] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
