Description

Technical Field

[0001] This utility model relates to the field of mine lighting technology, and in particular to a nighttime auxiliary lighting device. Background Technology

[0002] Because natural light is scarce in areas such as open-pit mines, transport roadways, and work platforms during nighttime operations in non-coal mines, and because the operations involve complex scenarios such as equipment scheduling, material transfer, and slope inspection, the need for clear visibility is directly related to personnel safety and production continuity. Therefore, auxiliary lighting devices are installed in non-coal mines at night to provide stable and sufficient illumination for nighttime work areas, improve visibility at the work face, ensure the safety of equipment operation, personnel movement, and the connection of various processes, and maintain the efficient and orderly progress of nighttime production.

[0003] A search revealed Chinese patent publication number CN212056948U, which discloses a nighttime auxiliary lighting device for mining production. The device includes a mounting plate, with a first stepper motor movably mounted on the top of the mounting plate. A housing is movably mounted on the top of the mounting plate, surrounding the first stepper motor. The housing is movably connected to the mounting plate via connecting bolts. A bearing clip, penetrating and extending into the housing, is fixedly mounted on the top of the housing. A rotating seat is movably mounted inside the bearing clip. The rotating seat is movably connected to the output shaft of the first stepper motor via a coupling. A second stepper motor is fixedly mounted on the front of the rotating seat. This nighttime auxiliary lighting device for mining production, by activating the first stepper motor, drives the rotating seat and lower frame plate to rotate horizontally via the output shaft and coupling. The lower frame plate, through a waterproof lamp tube, drives the waterproof lighting head to rotate horizontally, achieving a simple and convenient adjustment of the horizontal angle.

[0004] The aforementioned patent has the following shortcomings: Because strong direct light is needed at the underground tunneling face to clearly show the rock surface texture and equipment location, ensuring accurate operation of drilling and blasting, while underground transport roadways require uniform lighting to highlight the tracks, mine car connections, and roadway warning signs to prevent collisions, existing nighttime auxiliary lighting devices lack convenient light mode switching functions, making it difficult to quickly adapt to the different lighting needs of the two types of areas. This can lead to insufficient light intensity at the tunneling face affecting operational accuracy, and direct light in the transport roadway causing glare or blind spots, interfering with the visual judgment of workers and adversely affecting the safe progress of underground nighttime operations.

[0005] Therefore, a nighttime auxiliary lighting device is proposed. Utility Model Content

[0035] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0036] Example 1:

[0037] like Figures 1 to 5 As shown, a nighttime auxiliary lighting device includes a lamp housing 1, and further includes:

[0038] The rotating frame 2 is connected to both sides of the lamp housing 1 with damping rotation, and the top of the rotating frame 2 is equipped with a damping rotating seat 3.

[0039] The fixing structure 4 for fixing the device is set at the top of the damping rotary seat 3;

[0040] A reflector 10 is fixed inside the lamp housing 1. An LED light panel 8 is installed at the top of the reflector 10 and a focusing lens 11 is installed at the bottom of the reflector 10.

[0041] The movable structure 9 is set inside the lamp housing 1. The movable structure 9 includes a guide plate 905 fixed inside the lamp housing 1 and the top of the LED light panel 8 respectively. A folding frame 906 is rotatably connected to one side of the guide plate 905. A guide rod 907 rotatably connected to the folding frame 906 is slidably connected inside one side of the guide plate 905. A power component is set on one side inside the lamp housing 1.

[0042] The soft light structure 6, used for soft lighting, is located at the bottom of the lamp housing 1.

[0043] Heat dissipation fins 5 are fixed on the outer side wall of the lamp housing 1. The heat dissipation fins 5 are arranged at equal intervals on the outer side of the lamp housing 1. A lamp controller 7 is installed at the top inside the lamp housing 1. A fixing ring 12 that is fixedly connected to the lamp housing 1 is sleeved on the outer side of the focusing lens 11.

[0044] In this embodiment, the device is triggered to run by starting the lamp controller 7. At the same time, the LED lamp board 8 generates light after being powered on. The light source is initially focused by the reflector 10. Then, the light passes through the focusing lens 11 for further refraction and convergence, forming concentrated light for operation. The fixing ring 12 limits and fixes the focusing lens 11 to prevent it from shifting during operation. Meanwhile, the heat dissipation fins 5 on the outside of the lamp housing 1 continuously dissipate the heat generated during the operation of the device, preventing the internal temperature of the lamp housing 1 from being too high and affecting the normal operation of the components. To a certain extent, this ensures the stable and continuous output of the basic lighting function of the device. The damping rotating seat 3 and the rotating frame 2 can rotate around the lamp housing 1 with damping, realizing multi-dimensional adjustment of the lighting direction.

[0045] like Figures 1 to 3 As shown, the power assembly includes a reducer 902 fixed inside one side of the lamp housing 1. A drive motor 901 is mounted on the bottom of the reducer 902. A screw 904 rotatably connected to the lamp housing 1 is fixed to the output shaft end of the reducer 902. A moving block 903 connected to one of the guide rods 907 is threaded to the outside of the screw 904. The output shaft end of the drive motor 901 is connected to the input shaft end of the reducer 902. The folding frame 906 is a telescopic structure.

[0046] In this embodiment, when it is necessary to adjust the intensity and range of light according to different working scenarios in non-coal mines, the drive motor 901 is started to drive the reducer 902 to run, so that the reducer 902 drives the screw 904 to rotate. Then, the screw 904 drives the moving block 903 to move through the outer thread, so that the moving block 903 drives a set of guide rods 907 connected to slide inside the guide plate 905, and pushes the folding frame 906 to extend. The folding frame 906 drives the LED light panel 8 to move up and down, changing the distance between the LED light panel 8 and the focusing lens 11, so that the degree of light focusing changes. To a certain extent, the intensity and range of light can be flexibly adjusted to adapt to the different needs of strong direct light on the tunnel face and moderate lighting in the transport roadway.

[0047] Example 2:

[0048] A nighttime auxiliary lighting device, this embodiment is based on embodiment 1 with the following improvements, such as... Figures 1 to 5 As shown, the soft light structure 6 includes protective sleeves 605 fixed to the top of both sides of the lamp housing 1. An electric push rod 606 is fixed inside the guide plate 905. A movable ring 602 that is slidably connected to the fixed ring 12 is fixed to the telescopic end of the electric push rod 606. A connecting strip 604 is rotatably connected to the outside of the movable ring 602. A connecting frame 601 is rotatably connected to the bottom end of the connecting strip 604. A soft light cover 603 is fixed inside one side of the connecting frame 601. A rotating structure is formed between the connecting frame 601 and the fixed ring 12. The electric push rods 606 are symmetrically distributed on the vertical center line of the movable ring 602.

[0049] In this embodiment, when working in the underground transport roadway of a non-coal mine or operating equipment and instruments, and soft lighting is needed to avoid glare from strong light, the electric push rod 606 is activated to push the moving ring 602 to slide along the fixed ring 12. At the same time, the moving ring 602 pushes the connecting frame 601 to rotate around the connection point with the fixed ring 12 via the connecting strip 604. This causes the connecting frame 601 to drive the soft light cover 603 fixed on one side to rotate synchronously until the soft light cover 603 covers the light-emitting surface of the focusing lens 11. At this time, the light emitted by the LED light panel 8 is diffused by the soft light cover 603 to form uniform soft light, which to a certain extent eliminates the interference of strong light glare on the operator's vision, ensuring clear instrument readings and accurate equipment operation.

[0050] like Figure 5 As shown, the fixed structure 4 includes a housing 401 fixed to the top of the damping rotary seat 3. A bidirectional lead screw 407 is rotatably connected inside the housing 401. A rocker arm 405 is fixed to one side of the bidirectional lead screw 407. A movable seat 406 is threadedly connected to the outer side of the bidirectional lead screw 407 and slidably connected to the housing 401. A rotary seat 402 is fixed to the top of the movable seat 406. A clamping plate 403 is fixed to the top of the rotary seat 402. A strong magnetic seat 404 is fixed inside the top of the housing 401. The external threads on both sides of the outer surface of the bidirectional lead screw 407 are in opposite directions. The clamping plate 403 forms a rotating structure between the rotary seat 402 and the movable seat 406.

[0051] In this embodiment, when the device needs to be fixed on the equipment support, roadway wall or other usage position in a non-coal mine, the double-acting screw 407 inside the housing 401 is rotated by turning the crank handle 405. Since the threads on both sides of the outer surface of the double-acting screw 407 are opposite, when it rotates, it drives the two sets of movable seats 406 connected by the outer threads to slide relative to each other along the housing 401. The movable seats 406 drive the clamping plates 403 to move synchronously, so that the two sets of clamping plates 403 approach each other and clamp and fix in position. By pushing the clamping plates 403 to rotate around the rotating seat 402 and adhere to the upper surface of the housing 401, the strong magnetic seat 404 can be directly adsorbed onto the surface of the iron carrier, which to a certain extent ensures the stability of the device in the complex underground environment, while meeting the lighting needs of different working positions and angles.

[0052] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
