Description

Technical Field

[0001] This invention relates to the field of LED emergency lighting technology, specifically to a multi-degree-of-freedom adjustable explosion-proof LED emergency lighting device for mining. Background Technology

[0002] Mining LED emergency lighting is specifically designed for extreme environments such as mines. Utilizing high-brightness LED light sources, it boasts advantages such as high energy efficiency and long service life. In the event of a sudden power outage or accident, it can quickly and automatically illuminate, providing safe lighting to ensure the safe evacuation and rescue of miners. This lighting fixture complies with relevant safety standards and is suitable for coal mines, metal mines, and other similar fields, serving as a crucial guarantee for safe production in mines.

[0003] Chinese patent publication number CN207213885U discloses a mine-use explosion-proof and intrinsically safe LED emergency lighting lamp, including a main housing. The main housing consists of an upper explosion-proof cavity and a lower intrinsically safe cavity. A handle is provided at the top of the explosion-proof cavity. The explosion-proof cavity is divided into left and right chambers by a partition. A circuit control board is provided in the left chamber and a lithium battery pack is provided in the right chamber. The partition has wiring holes for connecting the lithium battery pack and the circuit control board. A protective tube is provided in the wiring holes. The protective tube includes a metal tube for electromagnetic interference resistance and rubber sleeves at both ends of the metal tube. A metal cap is fitted on the outer end of the rubber sleeve. The explosion-proof cavity and the intrinsically safe cavity are connected by an explosion-proof through-cavity terminal plate. An LED light source assembly is provided in the intrinsically safe cavity.

[0004] However, current LED emergency lighting has the following problems: if the angle or position needs to be adjusted after installation, the light fixture needs to be disassembled and reassembled, which increases the complexity of maintenance and management of LED emergency lighting and affects the efficiency of emergency response. The fixed angle of LED emergency lighting will lead to insufficient lighting in some areas of the mine, especially in complex environments such as mines and warehouses, and cannot effectively cover all areas that need lighting. Therefore, we have proposed a multi-degree-of-freedom adjustable explosion-proof LED emergency lighting device for mines. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a multi-degree-of-freedom adjustable explosion-proof LED emergency lighting device for mining, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-degree-of-freedom adjustable explosion-proof LED emergency lighting device for mining, comprising a mounting base, a rotating shell rotatably mounted on the bottom of the mounting base, a fixing device for restricting the rotating shell at the mounting base, a battery pack fixed inside the rotating shell, a Y-shaped frame fixed at the bottom of the rotating shell, a movable arm hinged to the bottom of the Y-shaped frame, an LED emergency lighting body fixedly mounted at the end of the movable arm away from the Y-shaped frame, the battery pack and the LED emergency lighting body connected by an explosion-proof wire, an adjustment device provided at the rotating shell, the adjustment device comprising an electric push rod fixed inside the rotating shell, the electric push rod connected to the battery pack by a wire, the telescopic end of the electric push rod vertically penetrating the bottom of the inner wall of the rotating shell, a push column fixed at the bottom of the telescopic end of the electric push rod, a long slot plate fixed to the outer surface of the movable arm, and the push column slidably mounted inside the long slot plate.

[0007] According to the above technical solution, the outer wall of the mounting base is provided with a plurality of openings, and the fixing device includes a threaded plate fixed to the inner wall of the opening of the mounting base. The outer wall of the threaded plate is threaded through and connected to a screw rod. A clamping plate is rotatably installed on the side of the screw rod near the center of the mounting base, and the clamping plate is slidably connected to the opening of the mounting base.

[0008] According to the above technical solution, the outer wall of the rotating shell is provided with an annular groove, which is used to accommodate the card plate.

[0009] According to the above technical solution, a protective cover is rotatably installed at the end of the movable arm away from the Y-shaped frame. A scraper is fixed on the inner wall of the protective cover. A circular groove is opened at the end of the protective cover near the movable arm. A spring is provided between the inner wall of the circular groove of the protective cover and the movable arm. A pull rope is fixed on the outer wall of the protective cover. The end of the pull rope away from the protective cover is fixed on the outer wall of the push column. A threading groove for the pull rope to pass through is opened on the outside of the movable arm.

[0010] According to the above technical solution, the scraper is in contact with the outer wall of the LED emergency lighting body.

[0011] According to the above technical solution, a protrusion ring is fixed on the outer wall of the protective cover, an elastic telescopic column is fixed on the swing end of the moving arm, an L-shaped striking rod is fixed at the bottom of the telescopic end of the elastic telescopic column, and an abutment column is fixed on the side of the vertical support of the L-shaped striking rod.

[0012] According to the above technical solution, a number of arc-shaped protrusions are evenly and equidistantly fixed on the outer circumference of the protrusion ring, and the abutting post is located on the movement trajectory of the arc-shaped protrusions of the protrusion ring.

[0013] According to the above technical solution, the end of the L-shaped striking rod near the protective cover is in contact with the lower outer wall of the protective cover.

[0014] According to the above technical solution, a locking device is provided at the rotating shell. The locking device includes a U-shaped plate fixed to the inner wall of the rotating shell. An elastic buckle is slidably installed inside the U-shaped plate. A cross rod is slidably installed through the bottom of the inner wall of the rotating shell. The top of the cross rod is hinged to the bottom of the outer wall of the elastic buckle via a hinge rod. A spring is provided between the cross rod and the bottom of the inner wall of the rotating shell. A limiting arc plate for limiting the position of the main body of the LED emergency lighting lamp is fixed at the bottom of the cross rod.

[0015] According to the above technical solution, the telescopic end of the elastic buckle is triangular, and the triangular telescopic end of the elastic buckle extends laterally through the inner wall of the rotating shell. A triangular annular groove that matches the triangular telescopic end of the elastic buckle is provided on the inner wall of the mounting base.

[0016] This invention provides a multi-degree-of-freedom adjustable explosion-proof LED emergency lighting device for mining. It has the following beneficial effects:

[0017] (1) The present invention, through the setting of the adjustment device, allows the staff to adjust the angle position of the LED emergency lighting body by rotating the rotating shell. At the same time, the telescopic end of the electric push rod drives the push column to move downward. The push column slides along the inside of the long slot plate, and the push column pushes the long slot plate to drive the moving arm and the LED emergency lighting body to swing downward, so that the staff can further adjust the angle position of the LED emergency lighting body.

[0018] (2) The present invention uses a push column, a pull rope, a protective cover, and a spring-loaded spring to drive a scraper to scrape off the dust adhering to the surface of the LED emergency lighting body. This avoids the problem that the surface of the LED emergency lighting body is covered by dust in the mine when the LED emergency lighting body has not been used for a long time, which affects the light intensity of the LED emergency lighting body. This ensures that the LED emergency lighting body can maintain the best working condition when needed to deal with emergencies. At the same time, the convex ring, the abutting column, and the elastic telescopic column work together to drive the L-shaped striking rod to impact the outer wall of the protective cover. The protective cover drives the scraper to vibrate. During the vibration, the scraper can effectively disperse the scraped dust and reduce the tendency of dust to re-adhere to the surface of the LED emergency lighting body.

[0019] (3) By setting up a locking device, when the main body of the LED emergency lighting lamp is not in use, the cross rod pushes the hinge rod to cause the triangular end of the elastic buckle to lock in the triangular ring groove. Therefore, when the main body of the LED emergency lighting lamp is not in use, simply rotating the screw to separate the plate from the ring groove of the rotating shell cannot remove the rotating shell from the mounting base. This makes it difficult for thieves unfamiliar with the device to understand its disassembly mechanism. Therefore, without mastering the complete disassembly process, it is difficult to easily steal the lamp of this invention, thereby improving the security of the equipment. At the same time, when the main body of the LED emergency lighting lamp is in use, the cross rod pulls the hinge rod to cause the elastic buckle to move laterally along the inner wall of the U-shaped plate. The triangular end of the elastic buckle separates from the triangular ring groove. At this time, when the workers in the mine need to remove the lamp for use, they can remove and use the lamp of this invention by rotating the screw to separate the plate from the ring groove of the rotating shell.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Please see Figure 1 - Figure 9 One embodiment of the present invention is: a multi-degree-of-freedom adjustable explosion-proof LED emergency lighting device for mining, including a mounting base 1, a rotating shell 5 rotatably mounted on the bottom of the mounting base 1, a fixing device 4 for restricting the rotating shell 5 at the mounting base 1, a battery pack 10 fixed inside the rotating shell 5, a Y-shaped frame 6 fixed at the bottom of the rotating shell 5, a movable arm 8 hinged to the bottom of the Y-shaped frame 6, an LED emergency lighting body 9 fixedly mounted at the end of the movable arm 8 away from the Y-shaped frame 6, the battery pack 10 and the LED emergency lighting body 9 connected by an explosion-proof wire 7, an adjustment device 2 provided at the rotating shell 5, the adjustment device 2 including an electric push rod 21 fixed inside the rotating shell 5, the electric push rod 21 connected to the battery pack 10 by a wire, the telescopic end of the electric push rod 21 vertically penetrating the bottom of the inner wall of the rotating shell 5, and a push column fixed at the bottom of the telescopic end of the electric push rod 21. 22. A long slotted plate 23 is fixed to the outer surface of the movable arm 8. The push column 22 is slidably installed inside the long slotted plate 23. The outer wall of the mounting base 1 has several openings. The fixing device 4 includes a threaded plate 41 fixed to the inner wall of the opening of the mounting base 1. The outer wall of the threaded plate 41 is threaded through and connected to a screw 42. A clamping plate 43 is rotatably installed on the side of the screw 42 near the center of the mounting base 1. The clamping plate 43 is slidably connected to the opening of the mounting base 1. The outer wall of the rotating shell 5 has an annular groove for accommodating the clamping plate 43. With the above structure, the operator can adjust the angle position of the LED emergency lighting body 9 by rotating the rotating shell 5. At the same time, the electric push rod 21 pushes the long slotted plate 23 through the push column 22, causing the movable arm 8 and the LED emergency lighting body 9 to swing downward, so that the operator can further adjust the angle position of the LED emergency lighting body 9.

[0032] A protective cover 24 is rotatably mounted on the end of the movable arm 8 away from the Y-shaped frame 6. A scraper 25 is fixed on the inner wall of the protective cover 24. A circular groove is opened on the end of the protective cover 24 near the movable arm 8. A spring-loaded spring 27 is provided between the inner wall of the circular groove of the protective cover 24 and the movable arm 8. A pull rope 26 is fixed on the outer wall of the protective cover 24. The end of the pull rope 26 away from the protective cover 24 is fixed on the outer wall of the push column 22. A wire groove is opened on the outside of the movable arm 8 for the pull rope 26 to pass through. The scraper 25 contacts the outer wall of the LED emergency lighting body 9. Through the above structure, the scraper 25 will scrape off the dust adhering to the surface of the LED emergency lighting body 9, thereby avoiding the problem that the surface of the LED emergency lighting body 9 will be covered by dust in the mine when it is not used for a long time, which will affect the light intensity of the LED emergency lighting body 9.

[0033] A protrusion ring 28 is fixed to the outer wall of the protective cover 24. An elastic telescopic column 29 is fixed to the swing end of the moving arm 8. An L-shaped striking rod 211 is fixed to the bottom of the telescopic end of the elastic telescopic column 29. An abutting column 210 is fixed to the side of the vertical support of the L-shaped striking rod 211. Several arc-shaped protrusions are evenly and equidistantly fixed to the outer circumference of the protrusion ring 28. The abutting column 210 is located on the movement trajectory of the arc-shaped protrusions of the protrusion ring 28. The end of the L-shaped striking rod 211 near the protective cover 24 contacts the lower outer wall of the protective cover 24. Through the above structure, the L-shaped striking rod 211 impacts the outer wall of the protective cover 24. The protective cover 24 drives the scraper 25 to vibrate. During the vibration, the scraper 25 can effectively disperse the scraped dust and reduce the tendency of dust to re-adhere to the surface of the LED emergency lighting body 9.

[0034] In use, workers fix the mounting base 1 in the mine using bolts. Simultaneously, workers can adjust the angle of the LED emergency lighting body 9 by rotating the rotating shell 5. It should be noted that the clamping plate 43 is located within the annular groove of the rotating shell 5, with a clearance fit between the clamping plate 43 and the rotating shell 5. The clamping plate 43 will not interfere with the rotation of the rotating shell 5. When the LED emergency lighting body 9 needs emergency use, the battery pack 10 will supply power to the LED emergency lighting body 9 through the explosion-proof wire 7, illuminating the LED emergency lighting body 9 for lighting operations. Simultaneously, the battery pack 10 will supply power to the electric push rod 21 through the wire. The telescopic end of the electric push rod 21 drives the push column 22 downwards. The push column 22 slides along the inside of the long slot plate 23, and pushes the long slot plate 23, causing the moving arm 8 and the LED emergency lighting body 9 to swing downwards, allowing workers to further adjust the angle of the LED emergency lighting body 9.

[0035] In special environments such as mines, if the LED emergency lighting body 9 is not used for a long time, its surface can easily become covered by thick dust from the mine. This can prevent the LED emergency lighting body 9 from working properly when needed. Therefore, as the push column 22 moves downward, it pulls the pull rope 26. The other end of the pull rope 26 causes the protective cover 24 to rotate at the moving arm 8. The protective cover 24 causes the spring 27 to contract, and the protective cover 24 also rotates the scraper 25. The scraper 25 scrapes off the dust adhering to the surface of the LED emergency lighting body 9, thus preventing the surface of the LED emergency lighting body 9 from being covered by dust from the mine when it is not used for a long time, which would affect the light intensity of the LED emergency lighting body 9. This ensures that the LED emergency lighting body 9 can maintain its best working condition when needed to cope with emergencies.

[0036] During the rotation of the protective cover 24, the protrusion ring 28 will also rotate. The arc-shaped protrusion of the protrusion ring 28 pushes the abutment post 210 to move the L-shaped striking rod 211 away from the protective cover 24. The L-shaped striking rod 211 also causes the telescopic end of the elastic telescopic post 29 to stretch. When the arc-shaped protrusion of the protrusion ring 28 no longer pushes the abutment post 210, under the elastic force of the elastic telescopic post 29, the telescopic end of the elastic telescopic post 29 causes the L-shaped striking rod 211 to reset and move. The L-shaped striking rod 211 impacts the outer wall of the protective cover 24, and the protective cover 24 causes the scraper 25 to vibrate. During the vibration, the scraper 25 can effectively disperse the scraped dust and reduce the tendency of dust to re-adhere to the surface of the LED emergency lighting body 9.

[0037] It should be noted that when the telescopic end of the electric push rod 21 moves to its reset position, the telescopic end of the electric push rod 21 will drive the push column 22 to reset. At this time, the push column 22 will no longer pull the pull rope 26, and the protective cover 24 will rotate in the opposite direction due to the elastic force of the spring 27, thereby resetting the protective cover 24 for the next rotation operation.

[0038] Please see Figure 1 - Figure 9Based on the above embodiments, in another embodiment of the present invention, a locking device 3 is provided at the rotating shell 5. The locking device 3 includes a U-shaped plate 31 fixed to the inner wall of the rotating shell 5. An elastic buckle 32 is slidably installed laterally inside the U-shaped plate 31. A cross rod 34 is slidably installed through the bottom of the inner wall of the rotating shell 5. The top of the cross rod 34 is hinged to the bottom of the outer wall of the elastic buckle 32 by a hinge rod 33. A spring is provided between the cross rod 34 and the bottom of the inner wall of the rotating shell 5. A limiting arc plate 35 for limiting the position of the LED emergency lighting body 9 is fixed at the bottom of the cross rod 34. The telescopic end of the elastic buckle 32 is triangular, and the triangular telescopic end of the elastic buckle 32 extends laterally through the inner wall. The inner wall of the rotating shell 5 and the inner wall of the mounting base 1 are provided with a triangular annular groove 36 that matches the triangular shape of the telescopic end of the elastic buckle 32. With the above structure, when the LED emergency lighting body 9 is not in use, the triangular shape of the telescopic end of the elastic buckle 32 will be locked in the triangular annular groove 36, making it difficult for thieves unfamiliar with the device to understand its disassembly mechanism. Therefore, without mastering the complete disassembly process, it is difficult to easily steal the lamp of this invention, thereby improving the security of the equipment. At the same time, when the LED emergency lighting body 9 is in use, the workers in the mine can disassemble and use the lamp of this invention by rotating the screw 42 to drive the card plate 43 to separate from the annular groove of the rotating shell 5.

[0039] When in use, with the LED emergency lighting body 9 not in use, the outer wall of the protective cover 24 will abut against the bottom of the limiting arc plate 35, causing the cross rod 34 to be in an upward state. The spring corresponding to the cross rod 34 is in a stretched state. At this time, the cross rod 34 pushes the hinge rod 33, causing the telescopic end of the elastic buckle 32 to be triangularly locked in the triangular ring groove 36. Therefore, when the LED emergency lighting body 9 is not in use, simply rotating the screw 42 to separate the locking plate 43 from the ring groove of the rotating shell 5 cannot remove the rotating shell 5 from the mounting base 1. This makes it difficult for thieves unfamiliar with the device to understand its disassembly mechanism. Therefore, without mastering the complete disassembly process, it is difficult to easily steal the lamp of this invention, thereby improving the security of the equipment.

[0040] When the main body 9 of the LED emergency lighting lamp is in use, that is, when the telescopic end of the electric push rod 21 pushes the long slot plate 23 through the push column 22 to drive the moving arm 8 to swing downward, the outer wall of the protective cover 24 no longer abuts against the limiting arc plate 35, the cross rod 34 is subjected to the corresponding spring force, the cross rod 34 resets and moves downward, and the cross rod 34 pulls the hinge rod 33 to drive the elastic buckle 32 to move laterally along the inner wall of the U-shaped plate 31. The telescopic end of the elastic buckle 32 separates from the triangular ring groove 36. At this time, when the workers in the mine need to remove the lamp for use, the workers in the mine can rotate the screw 42 to drive the card plate 43 to separate from the ring groove of the rotating shell 5 to realize the disassembly and use of the lamp of the present invention.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
