Description

Technical Field

[0001] The present application relates to the technical field of tunnel lamps, and in particular to a multi-light-emitting-surface tunnel lamp for mining. Background Art

[0002] Roadway lights are special lamps used for lighting in closed or semi-closed environments such as underground roadways, mines, and tunnels.

[0003] A laneway lamp in the related art includes a housing and a cover, wherein a receiving groove is provided on one side of the housing facing the cover, and the cover is used to block the receiving groove. A through hole is provided on the bottom wall of the receiving groove, and a transparent plate is arranged in the through hole.

[0004] Due to the high dust content in the mine, after the tunnel lamps have been used for a period of time, dust will adhere to the outer surface of the transparent plate, resulting in reduced lighting effects. Therefore, the transparent plate needs to be cleaned manually. When the tunnel lamps are located at a high position in the mine tunnel, workers need to use escalators to clean them, which is very inconvenient. Summary of the invention

[0005] In order to improve the problem that high-altitude tunnel lights are difficult to clean, the present application provides a mine-used tunnel light with multiple light-emitting surfaces.

[0006] The present application provides a multi-light-surface tunnel lamp for mining, which adopts the following technical solution: A multi-light-surface tunnel lamp for mining comprises a shell, one side of which is provided with a receiving groove, the interior of the shell comprises a first fixed surface, a fixing ring is arranged on the first fixed surface, the end surface of the fixing ring away from the first fixed surface is provided with a fixing hole, a through hole connected to the fixing hole is arranged on the shell, a transparent plate is arranged on the end surface of the fixing ring away from the first fixed surface, and a cleaning structure for cleaning the outer surface of the transparent plate is arranged on the fixing ring; two inner walls opposite to the fixing hole are provided with guide grooves in the shape of long strips, the cleaning structure comprises a guide block slidably arranged in the guide groove, a cleaning rod is arranged between the two guide blocks, the cleaning rod is in contact with the outer surface of the transparent plate, and a displacement component for driving the guide block to move along the length direction of the guide groove is arranged in the shell.

[0007] By adopting the above technical solution, the displacement component drives the guide block to move, and the guide block drives the cleaning rod to move together. Since the cleaning rod is in contact with the transparent plate, the cleaning rod cleans the dust on the surface of the transparent plate, thereby reducing the obstruction of light by foreign objects and thus reducing light loss. The cleaning rod is moved by the located component, so that the cleaning rod cleans the transparent plate of the high lane lamp without manual cleaning, which saves time and effort.

[0008] Optionally, the displacement assembly includes an operating frame arranged on the outside of the fixed ring and a driven magnet arranged on the side of the guide block facing the bottom wall of the guide groove. The end surface of the operating frame away from the fixed ring is provided with an operating hole in the shape of a long strip of hole. A screw rod is rotatably connected in the operating hole. The axial direction of the screw rod is consistent with the length direction of the guide groove. The screw rod is equipped with a fixed block that can move along the length direction of the screw rod. The end surface of the fixed block facing the fixed ring is provided with an active magnet. The active magnet is magnetically engaged with the driven magnet. The operating frame is provided with a driving motor for driving the screw rod to rotate.

[0009] By adopting the above technical solution, the driving motor drives the lead screw to rotate, so that the fixed block and the active magnet move together along the axial direction of the lead screw. Due to the magnetic attraction between the active magnet and the driven magnet, the active magnet drives the driven magnet and the guide block to move in the guide groove, so that the cleaning rod cleans the transparent plate.

[0010] Optionally, two first fixed surfaces are provided, and the two first fixed surfaces are symmetrically distributed. The shell also includes a second fixed surface, and the second fixed surface is located between the two first fixed surfaces. A linkage component that links the two screw rods is provided in the shell, and the linkage component includes a first bevel gear sleeved on the outside of the two screw rods and a second bevel gear rotatably connected to the second fixed surface, and the two first bevel gears are meshed with the second bevel gear.

[0011] By adopting the above technical solution, when one screw rotates, the first bevel gear rotates. Since the first bevel gear is meshed with the second bevel gear, the first bevel gear drives the second bevel gear to rotate, and the second bevel gear drives the first bevel gear in another shifting component to rotate, thereby realizing synchronous rotation of the two screws, so that one driving source can move the two cleaning rods; when one driving motor is damaged, the other driving motor can also realize the cleaning action of the two cleaning structures.

[0012] Optionally, slots are provided on the end faces of the two guide blocks that are close to each other, and the slot passes through the guide block toward the first fixed surface. An insert block inserted into the slot is provided on the end face of the cleaning rod that faces the guide block, and a hole is provided on the first fixed surface for the insert block to pass through, and a sealing block is provided in the hole.

[0013] By adopting the above technical solution, the blocking block blocks the socket, making it difficult for the guide block to pass through the socket, even the cleaning rod is not easy to separate from the fixing ring; the blocking block is taken out from the socket, and the guide block can be taken out from the guide groove, that is, the cleaning rod is removed from the alley light, which is convenient for the staff to align and replace, or the staff can use the cleaning rod to clean the ventilation hole.

[0014] Optionally, a positioning block is provided on the end surface of the blocking block along the length direction of the guide groove, and a positioning groove capable of being inserted into the positioning block is formed on the inner wall of the through hole.

[0015] By adopting the above technical solution, the positioning block is inserted into the positioning groove, so that the blocking block is not easy to be separated from the insertion hole, and the blocking block is restricted from moving in a direction perpendicular to the first fixing surface.

[0016] Optionally, a heat dissipation structure is provided on the shell, and mounting holes are provided on the two first fixing surfaces, and the heat dissipation structure includes a ventilation pipe passing through the mounting hole.

[0017] By adopting the above technical solution, the temperature inside the shell of the alley lamp rises when it is working. Even if the temperature inside the shell rises, the air in the shell exchanges heat with the ventilation pipe, and the ventilation pipe exchanges heat with the air inside the ventilation pipe. As the outside air enters the ventilation pipe, the original air in the ventilation pipe is replaced, thereby accelerating the heat dissipation of the alley lamp.

[0018] Optionally, the outer surface of the ventilation pipe is provided with a heat sink located in the receiving groove.

[0019] By adopting the above technical solution, the contact area with the air inside the ventilation duct is increased, the efficiency of heat exchange is improved, and the heat dissipation performance is improved.

[0020] Optionally, a baffle for covering the mounting hole is slidably provided on the outer surface of the shell.

[0021] By adopting the above technical solution, foreign matter such as dust can be prevented from entering the ventilation duct when the lane lights are not in use.

[0022] Optionally, the movement direction of the baffle is consistent with the sliding direction of the guide block, and a sliding hole in the shape of a long strip is opened on the side of the shell facing the baffle, and an operating rod inserted into the sliding hole is provided on the side of the baffle facing the shell, and the operating rod is slidably set in the sliding hole, and an operating strip is provided on the side of the fixed block away from the fixing ring, and a first push block and a second push block can be driven to move the operating rod on the side of the operating strip away from the fixed block, and the operating rod is located between the first push block and the second push block.

[0023] By adopting the above technical solution, when the fixed block moves along the length direction of the screw rod, the first push block and the second push block move together. When the first push block / the second push block contacts the operating rod, the movement of the fixed block will lead to the movement of the operating rod and the baffle, so that the baffle opens or closes the ventilation hole.

[0024] Optionally, one side of the shell includes a cover body for sealing the accommodating groove, a wire inlet pipe is provided on the side of the cover body, a wire inlet hole is provided on the wire inlet pipe, a wire clamping structure is provided on the wire inlet pipe, a notch connecting the wire inlet hole is provided on the outer circumferential surface of the wire inlet pipe, the wire clamping structure includes two mounting seats arranged on the outer circumferential surface of the wire inlet pipe, a clamping piece is provided in the notch, and a locking bolt connecting the clamping piece and the mounting seat is provided between the two.

[0025] By adopting the above technical solution, the cable is inserted into the cable entry hole, and the cable is clamped by the locking bolt and the clamping piece, so that the cable is not easy to move, and the cable is prevented from being pulled off and power off.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The displacement component drives the guide block to move, and the guide block drives the cleaning rod to move together. Since the cleaning rod contacts the transparent plate, the cleaning rod cleans the dust on the surface of the transparent plate, thereby reducing the obstruction of light by foreign objects and reducing light loss. The positioning component is used to realize the movement of the cleaning rod, so that the cleaning rod cleans the transparent plate of the high lane light without manual cleaning, which saves time and effort. 2.
