DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Example 1, see Figures 1 to 6 A lighting device for disaster prevention, mitigation and fire fighting evacuation includes a light box 1, on the top of which two emergency light bodies 101 are symmetrically fixedly installed, and also includes two protective covers 2 symmetrically arranged on the top of the light box 1, the protective covers 2 are made of retractable material or retractable bellows or are loosely installed, one end of the protective cover 2 is fixedly connected to the top of the light box 1, and two fixed frames 3 are symmetrically fixedly installed on the opposite inner sides of the two protective covers 2, the top of the light box 1 is symmetrically provided with two traction grooves 23, the bottom of the fixed frame 3 is slidably connected to the traction groove 23, and a pulley 24 is rotatably installed on the bottom of the traction groove 23, when the bottom of the fixed frame 3 slides inside the traction groove 23, the rolling friction between the pulley 24 and the inner bottom wall of the traction groove 23 replaces the sliding friction between the fixed frame 3 and the traction groove 23, thereby reducing the friction between the fixed frame 3 and the traction groove 23.

[0018] A support plate 4 is fixedly installed on the top of the light box 1, and a limit frame 5 is fixedly installed on one side of the support plate 4. An inverted L-shaped support rod 6 is slidably installed on the inner wall of the limit frame 5. A roller 26 is rotatably installed on the bottom of the support rod 6. Two support columns 27 are symmetrically rotatably installed on both sides of the support rod 6. Two support grooves 28 that are slidably connected to the corresponding support columns 27 are symmetrically provided on the relatively inner sides of the limit frame 5. When the bottom of the support rod 6 slides inside the limit frame 5, the rolling friction between the roller 26 and the inner bottom wall of the limit frame 5 reduces the friction between the support rod 6 and the limit frame 5. The rolling of the support column 27 inside the support groove 28 is to prevent the support rod 6 from tilting when moving. At the same time, the rolling friction between the support column 27 and the support groove 28 also reduces the friction between the support column 27 and the support groove 28.

[0019] A connecting plate 7 is fixedly installed at one end of the support rod 6 away from the support plate 4, and protective plates 8 are symmetrically fixedly installed at both ends of the connecting plate 7, and the two protective plates 8 are respectively placed in front of each emergency light body 101. The protective plates 8 are used to reinforce the daily anti-collision structure of the emergency light body 101 in non-emergency states.

[0020] A first traction rope 9 is fixedly installed on one end of the support rod 6 close to the limit frame 5, which is used to pull and limit the support rod 6. A spring 10 is fixedly installed on the side of the support rod 6 close to the support plate 4, and the spring 10 is sleeved on the outside of the first traction rope 9. The end of the spring 10 away from the support rod 6 is fixedly connected to the support plate 4. The front of the protective plate 8 is opened, and the shape of the hole is as follows: Figure 2 The indicated arrow shape shown can also be designed in a corresponding shape according to the actual fire protection requirements. The connecting plate 7 and the protective plate 8 are detachably fixed to facilitate the replacement of the type or adjustment of the arrow direction. The light box 1 and the emergency light body 101 are fixedly installed at the escape passage in the building. When the external power supply is not cut off, under the action of the first traction rope 9, the support rod 6 is placed inside the limit frame 5 near one end of the support plate 4, the spring 10 is compressed, and the protective plate 8 is also placed inside the protective cover 2. When the external power supply is cut off, the first traction rope 9 releases the traction of the support rod 6, and the two protective covers 2 also move to both ends respectively. The support rod 6 drives the connecting plate 7 and the protective plate 8 to move outward and pop out under the action of the elastic force of the spring 10, so that the emergency light body 101 can project light and shadow with an indicating function through the protective plate 8 after it is started, so that the emergency light body 101 can provide lighting function for the trapped persons while also guiding the correct escape direction, further increasing the success rate of the trapped persons in escaping.

[0021] For example 2, please refer to Figure 2 and Figure 5On the basis of the first embodiment, a traction plate 11 is fixedly installed at the bottom of the fixed frame 3, and a second traction rope 12 is symmetrically fixedly installed on the opposite outer side of the traction plate 11. A movable groove 25 is provided on the top of the light box 1, which is limited and slidably connected to the traction plate 11, so as to provide a movable space for the traction plate 11, and the second traction rope 12 is placed inside the movable groove 25. Two unwinding rollers 13 are symmetrically and rotatably installed inside the light box 1. One end of the second traction rope 12 away from the traction plate 11 movably passes through the top wall of the light box 1 and is fixedly connected to the unwinding roller 13. Two pairs of mounting boxes 14 are symmetrically and fixedly installed on the inner side wall of the light box 1. The mounting box 14 is sleeved on the outer sides of both ends of the unwinding roller 13, and a clockwork is fixedly installed inside the mounting box 14. One end of the clockwork away from the mounting box 14 is fixedly connected to the unwinding roller 13. A third traction rope 15 is fixedly installed at the bottom of the traction plate 11, so as to pull the traction plate 11. When the external power supply is not cut off, the third traction rope 15 can pull the traction plate 11. The two traction plates 11 are guided to fit together, so that the two protective covers 2 are stretched and the emergency light body 101 is protected to prevent dust from falling on the outer surface of the emergency light body 101 and affecting the lighting effect of the emergency light body 101. At the same time, the second traction rope 12 is not wound around the outer side of the unwinding roller 13, and the spring is in a tightened state and stores elastic potential energy. After power is cut off, the third traction rope 15 releases the traction on the traction plate 11. Under the action of the spring elastic force, the unwinding roller 13 rotates to rewind the second traction rope 12. The second traction rope 12 then drives the fixed frame 3 to move toward the unwinding roller 13 through the traction plate 11, so that the two protective covers 2 are retracted to remove the obstruction of the emergency light body 101, so that the emergency light body 101 provides lighting for the trapped person. The contraction and extension of the protective cover 2 can achieve the dust protection of the emergency light body 101 and can quickly remove the obstruction when the external power supply is cut off without affecting the normal operation of the emergency light body 101.

[0022] For example 3, please refer to Figures 4 to 6On the basis of the first embodiment, a winding roller 16 is rotatably installed inside the light box 1, and the ends of the first traction rope 9 and the third traction rope 15 away from the emergency light body 101 are slid through the top wall of the light box 1 and are fixedly connected to the winding roller 16. Two gears 17 are symmetrically fixedly installed on the outer side of the winding roller 16, and a bottom plate 18 is fixedly installed on the inner side wall of the light box 1. Two racks 19 are symmetrically slidably installed on the top of the bottom plate 18, and the two racks 19 are respectively meshed with the corresponding bottom plates 18 for transmission. A limiting slide plate 21 is fixedly installed on the bottom of the rack 19, and a limiting slide groove 22 is symmetrically opened on the top of the bottom plate 18, which is respectively connected to each limiting slide plate 21 for limited sliding. An electromagnet 20 is fixedly installed on the inner side wall of the light box 1, and a magnetic block is fixedly installed on one end of the two racks 19 close to the electromagnet 20. When the external power supply is not cut off, the electromagnet 20 is energized to generate magnetism, thereby having an adsorption effect on the magnetic block at one end of the two racks 19, and the meshing between the rack 19 and the winding roller 16 The winding roller 16 cannot rotate, so that the first traction rope 9 and the third traction rope 15 are wound and wound on the outside of the third traction rope 15. When the external power supply is cut off, under the action of the spring elastic force and the spring 10, the first traction rope 9 and the third traction rope 15 are stretched, and the winding on the outside of the winding roller 16 is gradually released. At the same time, when the winding roller 16 rotates, it drives the gear 17 to rotate, and the meshing transmission between the gear 17 and the rack 19 drives the rack 19 to slide. When the rack 19 slides, the relative sliding between the limiting slide plate 21 and the limiting slide groove 22 prevents the rack 19 from deviating. When the electromagnet 20 is energized, it limits the rack 19 and the gear 17 through the attraction between the electromagnet and the magnetic block, so that the first traction rope 9 and the third traction rope 15 are wound and wound on the outside of the winding roller 16, so that the protective cover 2 can be stretched out and the protective plate 8 placed inside the protective cover 2 is dust-proof and stored, reducing the occupied space of the protective plate 8 and preventing dust from accumulating on the surface of the protective plate 8.

[0023] Working principle: When the external power supply is not cut off, the electromagnet 20 is energized to generate magnetism, which has an adsorption effect on the magnetic block at one end of the two racks 19, and the racks 19 cannot move. The meshing between the racks 19 and the winding roller 16 makes the winding roller 16 unable to rotate, thereby allowing the first traction rope 9 and the third traction rope 15 to be wound and wound on the outside of the winding roller 16. At this time, the support rod 6 is placed inside the limit frame 5 at one end close to the support plate 4, the spring 10 is compressed, and the protective plate 8 is placed directly above the light box 1. The traction of the traction plate 11 by the third traction rope 15 makes the two traction plates 11 fit together, thereby making the two protective covers 2 extend to protect the emergency light body 101 and the protective plate 8 to prevent dust from falling on the outer surface of the emergency light body 101 and the protective plate 8 and affecting the lighting effect of the emergency light body 101. At the same time, the second traction rope 12 is not wound around the outside of the unwinding roller 13, and the spring is in a wound state, storing elastic potential energy. When the external power supply is cut off, the electromagnet 20 is no longer magnetic, and the electromagnetic The iron 20 cannot limit the rotation of the winding roller 16 by adsorption with the magnetic block. Under the action of the spring elastic force, the unwinding roller 13 rotates to rewind the second traction rope 12, and the second traction rope 12 drives the traction plate 11 to move in the direction of the unwinding roller 13. The traction plate 11 then drives the protective cover 2 to move outward and shrink through the fixed frame 3 to remove the obstruction of the emergency light body 101, so that the emergency light body 101 can provide lighting for the trapped person. At the same time, under the action of the elastic force of the spring 10, the support rod 6 drives the connecting plate 7 and the protective plate 8 to move outward and pop out, so that the emergency light body 101 can project light and shadow with direction indication through the protective plate 8 after it is started, helping the trapped person to identify the correct escape direction in a dimly lit environment, so that the emergency light body 101 can provide lighting function for the trapped person while also guiding the correct escape direction, reducing the possibility of the trapped person wasting escape time due to getting lost, thereby improving the success rate of escape.

[0024] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
