Description

Technical Field

[0001] The present invention belongs to the technical field of emergency lighting, and more specifically, particularly relates to an emergency lighting with a cleaning mechanism. Background Art

[0002] Emergency lighting is a device that provides lighting in case of power outage or emergency. Emergency lighting is equipped with a backup battery and can automatically work when the power is interrupted. Emergency lighting is usually installed in corridors, stairwells, exit passages and other places where emergency situations are likely to occur. Emergency lighting plays an important role in emergency situations such as fire and power outages. It can indicate safe passages for escapees and ensure their safety. It is an important safety equipment required for buildings and facilities, but existing emergency lighting has the following disadvantages:

[0003] The existing emergency lighting has no cleaning mechanism. When inspecting, the personnel need to disassemble and clean it. It is very inconvenient to disassemble and reinstall it each time. In addition, the general emergency lighting is installed at a high place, which is also very inconvenient for personnel to clean.

[0004] After the existing emergency lighting is installed with an additional cleaning mechanism, since the cleaning mechanism itself does not have a cleaning replacement reminder mechanism, the cleaning cotton of the cleaning mechanism itself becomes dirty after being used many times and the lighting cannot be cleaned anymore.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and an emergency lighting lamp with a cleaning mechanism is provided, in order to achieve a more practical purpose. Summary of the invention

[0008] Preferably, two metal boxes are fixedly installed on the front side wall of the emergency light box, and the two metal boxes are located below the two ratchets. The interiors of the two metal boxes are provided with arc grooves, and at least two metal sheets are placed inside the two arc grooves. A turntable is fixedly installed on the end of each micromotor output shaft, and the lower end of each rotating rod is fixedly installed outside the turntable. An annular groove is opened at the center of each lighting lamp, and a lower rotating column is rotatably installed on the side wall of the lower end of each cleaning frame, and each lower rotating column is installed inside the annular groove.

[0009] Preferably, each side wall of the cleaning rack is provided with an inner slide groove, each upper and lower ends of the inner slide groove are provided with grooves, each inner wall of the inner slide groove is installed with a baffle, each screw is installed between the baffle and the side wall of the cleaning rack, a connecting plate is provided on the back of each cleaning cotton, each connecting plate is installed inside the inner slide groove, and the upper and lower ends of each connecting plate are installed in the two grooves formed in the inner slide groove, three first micro springs are fixedly installed between each connecting plate and the cleaning cotton, rubber sheets are fixedly installed on the left and right sides of each cleaning cotton, and each cleaning cotton and rubber sheet are in contact with the surface of the lighting lamp.

[0010] Preferably, the cross-section of each support frame is L-shaped, and when each rotating rod rotates to contact the inner wall of the support frame, each cone will contact the ratchet, a spring is arranged between each cone and the inner wall of the fixed sleeve, and the surface of each cone is arc-shaped, and a cross bar is fixedly installed at the end of each support frame obliquely above the ratchet, and a round rod is fixedly installed on the inner wall of the end of each support frame, and an insert plate is rotatably sleeved on the surface of each round rod, and a second micro spring is fixedly installed above each insert plate and between the cross bar, and the end of each insert plate is inserted into the teeth of the ratchet, and a rectangular groove is opened on the outer surface of each cleaning frame, and a rotating shaft is installed inside each rectangular groove, and the bottom of each thin sheet is rotatably sleeved outside the rotating shaft.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In the present invention, the rotation of the turntable drives the cleaning frame to rotate through the connecting rod, and the rotation of the cleaning frame drives the cleaning cotton and the rubber sheet to clean the surface of the lighting lamp. When the connecting block drives the cone to rotate and pass through the ratchet, the cone will toggle the ratchet to rotate once, and when the cone rotates and resets and passes through the ratchet, the cone will retract into the fixed sleeve for a section, so that during normal maintenance, the device will automatically clean. In an emergency, the cleaning frame will continuously clean the surface of the lighting lamp to prevent the smoke from covering the fixed sleeve. At the same time, each rotation of the cleaning frame will drive the ratchet to rotate one circle. When the ratchet rotates and falls off the threaded rod, the user needs to replace the cleaning cotton, which serves as an automatic reminder.

[0013] In the present invention, the rotation of the turntable will drive the rotation of the rotating rod, the rotation of the rotating rod will drive the rotation of the connecting rod, the rotation of the connecting rod will drive the rotation of the connecting block, the rotation of the connecting block will drive the rotation of the cleaning frame, and the lower rotating column on the side wall at the end of the cleaning frame will rotate inside the annular groove. By setting a simple lower rotating column, the stability of the cleaning frame on the surface of the lighting lamp can be maintained, which can effectively overcome the shaking of the cleaning cotton and the rubber sheet when wiping the lighting lamp, thereby improving the cleaning stability.

[0014] In the present invention, when the cleaning rack rotates on the surface of the lighting lamp, it will drive the two thin sheets on the surface to rotate, and the two thin sheets will swing through the rotating shaft, and the support rod can provide better side wall support for the thin sheets. When encountering smoke, the two thin sheets will rotate and swing outside the lighting lamp continuously, which can disperse the smoke near the lighting lamp, thereby improving the visibility of the lighting lamp and effectively improving the usability in smoke scenes.

[0015] In the present invention, by adopting a three-layer matching design, the cleaning ability of the cleaning cotton and the rubber sheet on the surface of the lighting lamp can be improved, and it can be effectively applied to different scenarios. At the same time, when the cleaning cotton, the rubber sheet and the surface of the lighting lamp are attached, the first micro spring between the cleaning cotton and the connecting plate is in a compressed state, so the elastic force of the first micro spring can maintain the contact force between the cleaning cotton, the rubber sheet and the lighting lamp, effectively improving the cleaning contact surface.

[0016] In the present invention, through the surface contact between the cone and the ratchet, since the surface of the cone is arc-shaped, the cone will be forced to slide toward the inside of the fixed sleeve and drive the spring to compress. When the connecting rod drives the cone to rotate, the cone will drive the ratchet to rotate multiple times. After long-term rotation, the ratchet will fall off the threaded rod. At this time, the user can remove the baffle and the screws, and then replace the cleaning cotton and the rubber sheet. By designing the cleaning rack to drive the ratchet to rotate with each rotation, the personnel can be reminded to replace the cleaning cotton and the rubber sheet after a long rotation, which reduces the workload of personnel to actively inspect the lighting lamp and greatly improves the cleaning ability after replacement.

[0017] In the present invention, the two metal boxes on the side walls of the emergency light box are located just below the ratchet, and the metal box is large in size and has an arc-shaped groove inside. Therefore, when the ratchet falls into the metal box, the ratchet will hit multiple metal pieces, and the multiple metal pieces will collide with the inner wall of the arc-shaped groove to produce sound, which can alert the maintenance personnel at this moment, thereby serving as a reminder.

[0027] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] See also Figure 1-Figure 8 The present invention provides an emergency lighting device with a cleaning mechanism, comprising an emergency lighting device box 1, a test button is arranged on the side wall of the emergency lighting device box 1, two lighting devices 13 are arranged above the emergency lighting device box 1, micro motors 18 are fixedly installed on the back of the two lighting devices 13, a rotating rod 2 is arranged at the end of the output shaft of each micro motor 18, a connecting rod 21 is rotatably installed inside each rotating rod 2 near the end, a connecting block 22 is rotatably sleeved outside the end of each connecting rod 21, a fixing sleeve 32 is fixedly installed on the side wall of each connecting block 22, a cone 33 is slidably installed inside each fixing sleeve 32, a cleaning frame 31 is fixedly installed at the lower end of each connecting block 22, a cleaning cotton 28 is installed inside each cleaning frame 31, and each cleaning cotton 28 is used to clean the surface of the lighting device 13, a supporting frame 4 is fixedly installed below each lighting device 13, and each supporting frame 4 A threaded rod 45 is fixedly installed inside. When the connecting block 22 drives the cone 33 to rotate past the ratchet 46, the cone 33 will drive the ratchet 46 to rotate once, and when the cone 33 rotates and resets past the ratchet 46, the cone 33 will retract into the fixed sleeve 32 for a section. Therefore, during normal maintenance, the device can be automatically cleaned. In an emergency, the cleaning frame 31 will continuously clean the surface of the lighting lamp 13 to prevent the smoke from covering the fixed sleeve 32. At the same time, each rotation of the cleaning frame 31 will drive the ratchet 46 to rotate one circle. When the ratchet 46 rotates and falls off the threaded rod 45, the user needs to replace the cleaning cotton 28. A ratchet 46 is threadedly installed on the surface of each threaded rod 45, and each ratchet 46 is used in conjunction with the cone 33. Two thin sheets 36 are movably installed on the outer surface of each cleaning frame 31, and two support rods 37 are fixedly installed on the side walls of each thin sheet 36.

[0029] Two metal boxes 14 are fixedly installed on the front side wall of the emergency light box 1. The two metal boxes 14 are located below the two ratchet wheels 46. The interiors of the two metal boxes 14 are provided with arc grooves 15. At least two metal sheets 16 are placed inside the two arc grooves 15. A turntable 19 is fixedly installed at the end of the output shaft of each micro motor 18. The lower end of each rotating rod 2 is fixedly installed outside the turntable 19. An annular groove 17 is opened at the center of each lighting lamp 13. A lower rotating column 26 is rotatably installed on the side wall of the lower end of each cleaning frame 31. The rotation of the connecting block 22 will drive the cleaning frame 31 to rotate. The lower rotating column 26 on the side wall at the end of the cleaning frame 31 will rotate inside the annular groove 17. By setting a simple lower rotating column 26, the stability of the cleaning frame 31 on the surface of the lighting lamp 13 can be maintained, which can effectively overcome the shaking of the cleaning cotton 28 and the rubber sheet 29 when wiping the lighting lamp 13, and improve the stability of cleaning. Each lower rotating column 26 is installed inside the annular groove 17.

[0030] Each cleaning rack 31 has an inner slide groove 23 on its side wall, grooves are formed at the upper and lower ends of each inner slide groove 23, baffles 24 are installed on the inner wall of each inner slide groove 23, screws 25 are installed between each baffle 24 and the side wall of the cleaning rack 31, and a connecting plate 27 is provided on the back of each cleaning cotton 28, each connecting plate 27 is installed inside the inner slide groove 23, and the upper and lower ends of each connecting plate 27 are installed in the two grooves formed in the inner slide groove 23, and three first micro springs 3 are fixedly installed between each connecting plate 27 and the cleaning cotton 28. The combined design can improve the cleaning ability of the cleaning cotton 28 and the rubber sheet 29 on the surface of the lighting lamp 13, and can be effectively applied to different scenarios. At the same time, when the cleaning cotton 28, the rubber sheet 29 and the surface of the lighting lamp 13 are in contact, the first micro spring 3 between the cleaning cotton 28 and the connecting plate 27 is in a compressed state, so the elastic force of the first micro spring 3 can maintain the contact force between the cleaning cotton 28, the rubber sheet 29 and the lighting lamp 13. Rubber sheets 29 are fixedly installed on the left and right sides of each cleaning cotton 28, and each cleaning cotton 28 and rubber sheet 29 are in contact with the surface of the lighting lamp 13.

[0031] The cross section of each support frame 4 is L-shaped. When each rotating rod 2 rotates and contacts the inner wall of the support frame 4, each cone 33 will contact the ratchet 46. A spring is arranged between each cone 33 and the inner wall of the fixed sleeve 32, and the surface of each cone 33 is arc-shaped. A cross bar 43 is fixedly installed at the end of each support frame 4 obliquely above the ratchet 46, and a round rod 41 is fixedly installed on the inner wall of the end of each support frame 4. A plug plate 42 is rotatably sleeved on the surface of each round rod 41. A second micro spring 44 is fixedly installed above each plug plate 42 and between the cross bar 43. The ratchet 46 is rotated outside the threaded rod 45 under force, and the plug plate 42 is rotated under force. When the ratchet 46 rotates once, the plug plate 42 will be stuck in the next tooth of the ratchet 46 by the elastic force of the second micro spring 44. When the connecting block 22 is reset, the surface of the cone 33 and the ratchet 46 are in contact. Since the surface of the cone 33 is arc-shaped, the cone 33 will be forced to slide into the inside of the fixed sleeve 32 and drive the spring to compress. When the connecting rod 21 drives the cone 33 to rotate in a circular manner, the cone 33 will drive the ratchet 46 to rotate multiple times. The end of each plug plate 42 is inserted into the teeth of the ratchet 46. A rectangular groove 34 is provided on the outer surface of each cleaning frame 31. A rotating shaft 35 is installed inside each rectangular groove 34. The bottom of each thin sheet 36 is rotatably sleeved outside the rotating shaft 35.

[0032] Working principle:

[0033] In the first step, a connecting frame (existing connecting frame structure) is provided between the emergency light box 1 and the two lighting lamps 13. In the initial state, the connecting rod 21 is located at the connecting frame between the lighting lamp 13 and the emergency light box 1, and is in a state away from the ratchet 46. The emergency light box 1 needs to be inspected at regular intervals. The user needs to press the inspection button on the emergency light box 1. At this time, the emergency light box 1 cuts off the charging power supply, and the internal storage battery supplies power to the two lighting lamps 13 and the micro motor 18. At this time, the two lighting lamps 13 start to illuminate, and at the same time, the micro motor 18 drives the turntable 19 to rotate. The rotation of the turntable 19 drives the cleaning frame 31 to rotate through the connecting rod 21, and the rotation of the cleaning frame 31 drives the cleaning cotton 28 and the rubber sheet 29 clean the surface of the lighting lamp 13. When the connecting block 22 drives the cone 33 to rotate past the ratchet 46, the cone 33 will drive the ratchet 46 to rotate once, and when the cone 33 rotates and resets past the ratchet 46, the cone 33 will retract into the fixing sleeve 32 for a section. In this way, the device will automatically clean during normal maintenance. In an emergency, the cleaning frame 31 will continuously clean the surface of the lighting lamp 13 to prevent the smoke from covering the fixing sleeve 32. At the same time, each rotation of the cleaning frame 31 will drive the ratchet 46 to rotate one circle. When the ratchet 46 rotates and falls off the threaded rod 45, the user needs to replace the cleaning cotton 28, which serves as an automatic reminder.

[0034] In the second step, when the micro motor 18 drives the turntable 19 to rotate, the rotation of the turntable 19 will drive the rotation of the rotating rod 2, the rotation of the rotating rod 2 will drive the rotation of the connecting rod 21, the rotation of the connecting rod 21 will drive the rotation of the connecting block 22, the rotation of the connecting block 22 will drive the cleaning frame 31 to rotate, and the lower rotating column 26 of the side wall at the end of the cleaning frame 31 will rotate inside the annular groove 17. By setting a simple lower rotating column 26, the stability of the cleaning frame 31 on the surface of the illuminating lamp 13 can be maintained, which can effectively overcome the shaking of the cleaning cotton 28 and the rubber sheet 29 when wiping the illuminating lamp 13, thereby improving the cleaning stability;

[0035] When the cleaning frame 31 rotates on the surface of the illuminating lamp 13, it drives the two thin sheets 36 on the surface to rotate. The two thin sheets 36 will swing through the rotating shaft 35, and the support rod 37 can provide a good side wall support force for the thin sheets 36. When encountering smoke, the two thin sheets 36 rotate and swing outside the illuminating lamp 13 continuously, which can disperse the smoke near the illuminating lamp 13, so that the visibility of the illuminating lamp 13 is improved, and the use ability in smoke scenes is effectively improved;

[0036] When the cleaning frame 31 drives the cleaning cotton 28 and the rubber sheet 29 to rotate, the cleaning cotton 28 will wipe off the light dust on the surface of the lighting lamp 13, and the rubber sheets 29 on both sides of the cleaning cotton 28 can wipe off the grease and dust on the surface of the lighting lamp 13. By adopting a three-layer matching design, the cleaning ability of the cleaning cotton 28 and the rubber sheet 29 on the surface of the lighting lamp 13 can be improved, and it can be effectively applied to different scenes. At the same time, when the cleaning cotton 28, the rubber sheet 29 and the surface of the lighting lamp 13 are attached, the first micro spring 3 between the cleaning cotton 28 and the connecting plate 27 is in a compressed state. Therefore, the elastic force of the first micro spring 3 can maintain the contact force between the cleaning cotton 28, the rubber sheet 29 and the lighting lamp 13, effectively improving the cleaning contact surface.

[0037] In the third step, since the cross section of the support frame 4 is L-shaped, when the connecting rod 21 rotates to the inner wall of the support frame 4, the cone 33 on the surface of the connecting block 22 will pass over the ratchet 46. When the cone 33 contacts the ratchet 46, since the contact surface between the cone 33 and the ratchet 46 is a plane, the cone 33 will trigger the teeth of the ratchet 46. The ratchet 46 is forced to rotate outside the threaded rod 45. At the same time, the plug plate 42 is forced to rotate. When the ratchet 46 rotates once, the plug plate 42 will be stuck on the next tooth of the ratchet 46 by the elastic force of the second micro spring 44. When the connecting block 22 is reset, the surface of the cone 33 and the ratchet 46 are in contact. Since the surface of the cone 33 is arc-shaped, Therefore, the cone 33 will be forced to slide into the fixing sleeve 32 and drive the spring to compress. When the connecting rod 21 drives the cone 33 to rotate, the cone 33 will drive the ratchet 46 to rotate multiple times. After a long period of rotation, the ratchet 46 will fall off the threaded rod 45. At this time, the user can remove the baffle 24 and the screw 25, and then replace the cleaning cotton 28 and the rubber sheet 29. By designing the cleaning frame 31 to drive the ratchet 46 to rotate each time, the cleaning cotton 28 and the rubber sheet 29 can be reminded to replace the cleaning cotton 28 and the rubber sheet 29 after a long period of rotation, which reduces the workload of the personnel to actively inspect the lighting lamp 13 and greatly improves the cleaning ability after replacement.

[0038] When the ratchet 46 falls, since the two metal boxes 14 on the side wall of the emergency light box 1 are located below the ratchet 46, and the metal box 14 is large in size and has an arc groove 15 inside, when the ratchet 46 falls into the metal box 14, the ratchet 46 will hit multiple metal pieces 16, and the multiple metal pieces 16 will collide with the inner wall of the arc groove 15 and make sounds, which can alert the maintenance personnel at this moment, thereby serving as a reminder.

[0039] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
