Description

Technical Field

[0001] The present invention relates to the field of lighting technology, and in particular to a distributed emergency lighting system for high-speed rail transportation. Background Art

[0002] The high-speed railway station consists of a waiting hall, equipment area and platform. The high-speed railway station is a densely populated area for the transportation of people and goods. In the event of a fire, casualties and property losses should be minimized. In order to deal with fires and other emergencies, the high-speed railway station is equipped with a fire sprinkler system and an emergency lighting system. Among them, emergency lighting mainly includes backup lighting and evacuation lighting. When the high-speed railway station loses power due to an electrical fault, evacuation lighting is the lighting part that instructs people in the station to find a safe exit; while backup lighting is the part that provides emergency lighting for safe passages, including emergency lighting lamps, which are generally installed in a distributed manner in the walkways, platforms and other locations of the high-speed railway station, and are the more commonly used emergency lighting parts.

[0003] There are still many deficiencies in the current fire emergency lights. First, most traditional double-head fire emergency lighting lamps use gas discharge light sources such as fluorescent lamps as light sources, which consume a lot of power and are not conducive to energy conservation and environmental protection; second, fire emergency lights only work when the power fails, and their functions are single. They are usually idle, and places where fire emergency lamps are usually installed will also install ordinary lighting lamps, which causes repeated waste of lamps; third, in the event of an emergency such as a fire, the water sprayed by the fire sprinkler will have a certain impact on the nearby fire emergency lights.

[0004] In view of the deficiencies in the prior art, the present invention conceives to combine fire emergency lights with ordinary lighting lamps, designs a green lighting emergency LED dual-purpose lamp, and these lamps form a distributed high-speed railway station lamp control system. The system not only realizes the lighting function of the normal high-speed railway station, but also can realize the emergency lighting function in the case of abnormal power outages, etc., changing the defect of the traditional lighting system with a single function. The lamp has two lighting functions, normal and emergency, and two power supply modes, mains and battery. It is usually used for corridor lighting. When the mains is normal, the mains will give priority to power supply. In case of emergency, it will enter the fire mode, the fire area will be fully illuminated, and the battery will be used to supply power in the event of abnormal power outages. It solves the problem of space and energy waste caused by the independent functions of traditional lighting lamps and emergency lights. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention provides a distributed emergency lighting system for high-speed rail transportation.

These lamps form a distributed high-speed rail station lamp control system.

DETAILED DESCRIPTION

[0033] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0034] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] Example 1 The present invention provides a distributed emergency lighting system for high-speed rail transportation. Figure 1-Figure 5, comprising a shell 1, wherein a lighting lamp 2 is symmetrically arranged inside the shell 1, and the lighting lamp 2 comprises a lamp body 3, and a front end portion of the lamp body 3 is provided with a white LED lamp bead 4 for providing ordinary lighting and a yellow LED lamp bead 5 for providing emergency lighting, a front end surface of the shell 1 is provided with a soft light plate 6, and a circular opening 7 is respectively arranged on the soft light plate 6 directly in front of the two lighting lamps 2, and a double-light-transmitting light plate 8 is arranged at the rear side position of the soft light plate 6 inside the shell 1, and the double-light-transmitting light plate 8 comprises a plate body 81, and circular soft light plates 82 for blocking the two circular openings 7 are symmetrically arranged on the left and right sides of the plate body 81, and circular transparent plates 83 for blocking the two circular openings 7 are symmetrically arranged on the upper and lower sides of the plate body 81, and a switching shaft 84 is coaxially arranged in the middle of the plate body 81, and a light plate switching mechanism 9 for rotating the switching shaft 84 is also arranged at the upper end of the shell 1. The present invention combines the fire emergency light (yellow LED lamp bead 5) with the ordinary lighting lamp (white LED lamp bead 4) to design a green lighting emergency LED dual-purpose lamp, and these lamps form a distributed high-speed railway station lamp control system. The system not only realizes the lighting function of the normal high-speed railway station, but also can realize the emergency lighting function in the case of abnormal power failure, etc., changing the defect of the single function of the traditional lighting system. The lamp has two lighting functions, normal and emergency, and two power supply modes, mains and battery. It is usually used for corridor lighting. When the mains power is normal, the mains power is given priority. When an emergency occurs, it enters the fire mode, the fire area is fully illuminated, and the battery is used to supply power when the power is abnormally cut off. The problem of space and energy waste caused by the independent functions of traditional lighting lamps and emergency lights is solved. In daily lighting, the white LED lamp bead 4 cooperates with the circular soft light plate 82 to provide brighter and more comfortable lighting, but in the case of a fire accompanied by a lot of smoke, the penetration effect of the white LED lamp bead 4 is far less than that of the yellow LED lamp bead 5. Therefore, in emergency situations such as fire, the yellow LED lamp bead 5 and the circular transparent plate 83 are used to provide strong penetrating light.

[0036] As a specific implementation method, refer to Figure 2 , Figure 6 and Figure 7The light board switching mechanism 9 includes a double-threaded screw 91, which is vertically arranged. The upper and lower ends of the double-threaded screw 91 are connected to the inner wall of the shell 1 through bearings respectively. The upper end of the double-threaded screw 91 is provided with a first thread 92, and the lower end of the double-threaded screw 91 is provided with a second thread 93. The first thread 92 and the second thread 93 have opposite rotation directions, and the pitch of the first thread 92 is smaller than the pitch of the second thread 93. The first thread 92 is adapted with a first ball nut block 94, and the second thread 93 is adapted with a second ball nut block 95. The lower end of the first ball nut block 94 is provided with a vertically arranged electric cylinder 96, and the lower end of the electric cylinder 96 is connected to the inner wall of the shell 1 through a connecting seat. The second ball nut block 95 is vertically downwardly provided with a first rack 97, and the first rack 97 is adapted with a first gear 98. Under normal lighting, the electric cylinder 96 is in a retracted state, and the circular soft light plate 82 is located at the circular opening 7 to soften the light of the white LED lamp beads 4; when emergency lighting is needed, the white LED lamp beads 4 are turned off and the yellow LED lamp beads 5 are turned on. Through the extension of the electric cylinder 96, the first ball nut block 94 can be driven to move upward, thereby driving the double-threaded screw 91 to rotate and then driving the second ball nut block 95 to move downward, thereby causing the first rack 97 to move downward, and then causing the first gear 98 to rotate 90 degrees around the axis. At this time, the circular transparent plate 83 is located at the circular opening 7 to enhance the light of the yellow LED lamp beads 5. The setting of the double-threaded screw 91 can make the first rack 97 have a larger displacement when the extension of the electric cylinder 96 is small.

[0037] Specifically, refer to Figure 3 The length direction of the switching shaft 84 is horizontally arranged in the front-to-back direction. The front and rear ends of the switching shaft 84 are respectively connected to the front and rear side surfaces of the housing 1 through bearings. The first gear 98 is coaxially arranged on the switching shaft 84.

[0038] Specifically, the light panel switching mechanism 9 also includes a first guide rod 99, which is arranged parallel to the double-threaded screw 91, and the upper and lower ends of the first guide rod 99 are respectively connected to the inner wall of the shell 1, and the first ball nut block 94 and the second ball nut block 95 are respectively provided with first guide holes adapted to the first guide rod 99.

[0039] Specifically, two electric cylinders 96 are provided, and the two electric cylinders 96 are symmetrically arranged at the left and right ends of the first ball nut block 94, and the two electric cylinders 96 work synchronously.

[0040] Specifically, a plurality of the white LED lamp beads 4 and the yellow LED lamp beads 5 are provided, and the plurality of the white LED lamp beads 4 and the yellow LED lamp beads 5 are alternately arranged on the lamp body 3 in a circular array.

[0041] In order to facilitate the determination of whether an emergency situation is caused by a fire, as a specific implementation method, refer to Figure 1 The lower end surface of the housing 1 is also provided with a smoke sensor 16 for detecting the smoke content near the housing 1 and a temperature sensor 17 for detecting the temperature near the housing 1. Through the operation and detection of the smoke sensor 16 and the temperature sensor 17, the central processor determines whether a fire occurs.

[0042] In order to ensure the heat dissipation effect inside the housing 1 and the protection of the interior of the housing 1 when the fire sprinkler system is started, as a specific implementation method, refer to Figure 2 and Figure 8 The left and right sides of the shell 1 are respectively provided with first heat dissipation holes 10, and the left and right ends inside the shell 1 are respectively provided with first shielding components 11 for shielding the first heat dissipation holes 10, and the first shielding component 11 includes a third screw rod 111 and a third guide rod 114, and the third screw rod 111 and the third guide rod 114 are both vertically arranged, and the third screw rod 111 is adapted with a third ball nut block 112, and the third ball nut block 112 is vertically downwardly provided with a first shielding plate 113, and the first shielding plate 113 is provided with a third sealing gasket 115 on one side of the first shielding plate 113 close to the first heat dissipation hole 10, and the third ball nut block 112 is provided with a third guide hole adapted to the third guide rod 114, and the upper end of the third screw rod 111 is transmitted to the double-threaded screw rod 91 through the transmission assembly 15. During normal lighting, the first shielding plate 113 is located above the first heat dissipation hole 10, and the heat inside the housing 1 can be dissipated through the first heat dissipation hole 10. When a fire is detected, the electric cylinder 96 is extended to a large extent, which can drive the first ball nut block 94 to move upward, thereby driving the double-threaded screw 91 to rotate, and then driving the second ball nut block 95 to move downward, so that the first rack 97 moves downward, and then the first gear 98 rotates 270 degrees around the axis. At this time, the circular transparent plate 83 is located at the circular opening 7 position to enhance the light of the yellow LED lamp bead 5, and the downward movement of the first shielding plate 113 can cover all the first heat dissipation holes 10. When the emergency is not caused by a fire, the first gear 98 rotates only 90 degrees around the axis, and the downward movement of the first shielding plate 113 cannot cover all the first heat dissipation holes 10.

[0043] As a specific implementation method, refer to Figure 2 A heat dissipation fan 19 is also provided at the lower end of the shell 1.

[0044] As a specific implementation method, refer to Figure 2 , Figure 6 and Figure 8 The transmission assembly 15 includes a transmission rod 151, the length direction of the transmission rod 151 is horizontally arranged in the left-right direction, one end of the transmission rod 151 close to the double-threaded screw 91 is connected to the double-threaded screw 91 through a first bevel gear pair 152, and the other end of the transmission rod 151 is provided with a third bevel gear pair 116 for connecting to the third screw 111. Through the rotation of the double-threaded screw 91, the transmission rod 151 can be driven to rotate through the meshing transmission of the first bevel gear pair 152, and the rotation of the transmission rod 151 and the meshing transmission of the third bevel gear pair 116 can realize the rotation of the third screw 111, thereby realizing the upward or downward movement of the third ball nut block 112 and the first shielding plate 113.

[0045] Example 2 When traditional emergency lighting is dissipating heat, a number of heat dissipation holes are generally set on the shell 1, but this method is easily splashed by water from the fire sprinkler system, affecting protection. Although a first shielding component 11 is set in Example 1, if the shielding is not timely, it will also affect the devices inside the shell 1.

[0046] To this end, the embodiment of the present invention further refers to Figure 2 and Figure 8 The left and right sides of the housing 1 are provided with secondary waterproof components 12, respectively. The secondary waterproof components 12 include a second housing 121, a waterproof cavity 123 is formed between the second housing 121 and the side of the housing 1, a second heat dissipation hole 122 is provided on the side of the second housing 121 away from the housing 1, a second shielding component 13 for shielding the second heat dissipation hole 122 is provided inside the waterproof cavity 123, a bottom opening 124 is provided at the lower end of the waterproof cavity 123, and a hydrophobic component 14 is provided at the bottom opening 124. By providing the secondary waterproof components 12 on the left and right sides of the housing 1, a double-layer side wall structure is formed between the second housing 121 and the housing 1, which increases the difficulty of water flow directly entering the interior of the housing 1, and the first heat dissipation hole 10, the second heat dissipation hole 122 and the heat dissipation fan 19 can form a heat dissipation path. At the same time, a small amount of water flow passing through the second heat dissipation hole 122 can be discharged along the waterproof cavity 123 and the bottom opening 124, thereby achieving an effective waterproof effect in a comprehensive manner.

[0047] As a specific implementation method, refer to Figure 8The second shielding assembly 13 includes a fourth screw rod 131 and a fourth guide rod 134, both of which are arranged vertically, and a fourth ball nut block 132 is adapted to the fourth screw rod 131, and a second shielding plate 133 is vertically arranged downward on the fourth ball nut block 132, and a fourth sealing gasket 135 is arranged on one side of the second shielding plate 133 close to the second heat dissipation hole 122, and a fourth guide hole adapted to the fourth guide rod 134 is arranged on the fourth ball nut block 132, and the upper end of the fourth screw rod 131 is also transmitted to the double-thread screw rod 91 through the transmission assembly 15. The end of the transmission rod 151 away from the first bevel gear pair 152 is also provided with a fourth bevel gear pair 136 for connecting with the fourth screw rod 131. By rotating the double-threaded screw 91 and the meshing transmission of the first bevel gear pair 152, the transmission rod 151 can be driven to rotate. By rotating the transmission rod 151 and the meshing transmission of the fourth bevel gear pair 136, the fourth screw 131 can be rotated, thereby realizing the upward or downward movement of the fourth ball nut block 132 and the second baffle plate 133, thereby realizing the closing and opening of the second heat dissipation hole 122.

[0048] As a specific implementation method, refer to Figure 2 and Fig. 9 The hydrophobic component 14 includes a first elastic sheet 141 which is arranged obliquely downward and a second elastic sheet 142 which is opposite to the first elastic sheet 141 and obliquely downward. The upper end of the first elastic sheet 141 is connected to the lower end of the side surface of the shell 1, and the upper end of the second elastic sheet 142 is connected to the lower end of the inner wall of the second shell 121. In a natural state, the first elastic sheet 141 presses against the second elastic sheet 142 from top to bottom, and the second elastic sheet 142 is longer than the first elastic sheet 141 to form a cross space away from the waterproof cavity 123; and the first elastic sheet 141 is connected to a third elastic sheet 143 which is obliquely downward in the cross space. In a natural state, the third elastic sheet 143 presses against the second elastic sheet 142 from top to bottom. The first elastic sheet 141, the second elastic sheet 142 and the third elastic sheet 143 together enclose a triangular space 144.

[0049] The natural state is a state without water flow force, and the first elastic sheet 141, the second elastic sheet 142 and the third elastic sheet 143 are made of materials with certain rigidity and toughness. Fig. 9 As shown, when the water flow in the waterproof cavity 123 impacts from top to bottom, a water outlet gap can be relatively easily formed between the first elastic sheet 141 and the second elastic sheet 142. When the water flow outside the waterproof cavity 123 impacts from bottom to top, due to the stability of the triangular space 144, it is difficult to form a water inlet gap under the action of the water flow, which can effectively prevent the water from flowing back into the waterproof cavity 123.

[0050] Example 3 In Example 2, when a fire occurs, the first shielding plate 113 and the second shielding plate 133 respectively block the first heat dissipation hole 10 and the second heat dissipation hole 122, which makes it difficult for the heat inside the shell 1 to be discharged to the outside, which affects the heat dissipation of the components inside the shell 1 to a certain extent, and seriously affects the life of the components for a long time. Based on this, this embodiment provides a distributed emergency lighting system for high-speed rail transportation, referring to Figure 2 , Fig.10 and Fig.11 A closed heat dissipation mechanism is also provided at the lower end of the shell 1, and the closed heat dissipation mechanism includes a heat dissipation component 181 for making the gas on the lower end surface of the shell 1 flow, and the heat dissipation component 181 includes a vertically arranged driving rod 1811, and the lower end of the driving rod 1811 is connected to the lower end surface of the shell 1 through a sealed bearing, and the lower end of the driving rod 1811 is provided with a fan blade 1812, and the upper end of the driving rod 1811 is coaxially provided with a second gear 1813, and the second gear 1813 is adapted to be meshed with a second rack 1814, and the second rack 1814 is horizontally arranged in the left and right directions, and a rack sliding cavity 1815 adapted to the second rack 1814 is provided inside the shell 1, and a magnetic magnet 1816 is also provided at one end of the second rack 1814 close to the middle part of the shell 1. When the second rack 1814 moves in the rack sliding cavity 1815, it can drive the second gear 1813 meshing therewith to rotate around the axis. The rotation of the second gear 1813 around the axis can drive the driving rod 1811 to rotate around the axis, and then drive the fan blades 1812 located at the lower end surface of the shell 1 to rotate. The rotation of the fan blades 1812 can drive the flow of gas on the lower end surface of the shell 1, accelerate the heat exchange on the lower end surface of the shell 1, reduce the temperature of the lower end surface of the shell 1, and then reduce the temperature inside the shell 1.

[0051] As a specific implementation method, refer to Fig.10 , there are a plurality of driving rods 1811, which are sequentially arranged along the length direction of the second rack 1814, and a fan blade 1812 is respectively arranged at the lower end of each driving rod 1811, and a second gear 1813 meshing with the second rack 1814 is respectively coaxially arranged at the upper end of each driving rod 1811. The synchronous rotation of the plurality of second gears 1813 can drive the rotation of the plurality of fan blades 1812, thereby accelerating the flow of gas at the lower end surface of the shell 1, further accelerating the heat exchange at the lower end surface of the shell 1, further reducing the temperature of the lower end surface of the shell 1, and further reducing the temperature inside the shell 1.

[0052] As a specific implementation method, refer to Figure 2The heat dissipation components 181 are provided with two, and the two heat dissipation components 181 are symmetrically arranged on the left and right sides of the lower end of the shell 1. The flow of gas at the lower end surface of the shell 1 is further accelerated, the heat exchange at the lower end surface of the shell 1 is further accelerated, the temperature of the lower end surface of the shell 1 is further reduced, and the temperature inside the shell 1 is further reduced.

[0053] As a specific implementation method, refer to Figure 2 The closed heat dissipation mechanism also includes a magnetic drive component 182 for moving the second rack 1814 along its length direction. The magnetic drive component 182 includes a rectangular electromagnet 1821. The length direction of the electromagnet 1821 is horizontally arranged in the left-right direction, and the electromagnet 1821 is located between the two heat dissipation components 181. The middle part of the electromagnet 1821 is connected to the lower end of the first rack 97 through an extension rod 1822. During ordinary lighting and non-fire emergency lighting, the electromagnet 1821 is not energized and is located a certain distance above the rack sliding cavity 1815; when fire emergency lighting is performed, after the first gear 98 rotates 270 degrees, the first rack 97 reaches the maximum downward displacement, and the electromagnet 1821 follows the downward movement of the first rack 97 to reach the position between the two second racks 1814. At this time, the electromagnet 1821 is energized, and the adsorption or repulsion between the magnetic attractor 1816 and the electromagnet 1821 can drive the two second racks 1814 to move toward or away from the electromagnet 1821, thereby driving the plurality of second gears 1813 to rotate around the axis, and finally achieving the purpose of rotating the plurality of fan blades 1812.

[0054] As a specific implementation method, refer to Fig.11In the above, since the magnetic field of the electromagnet 1821 is fixed, the two second racks 1814 can only move in one direction, and the magnetic field of the electromagnet 1821 needs to be converted to achieve the reciprocating movement of the two second racks 1814 in the rack sliding cavity 1815 respectively. For this purpose, one of the driving rods 1811 is also provided with a magnetic field reversing component 183 for converting the magnetic direction of the electromagnet 1821, and the magnetic field reversing component 183 includes an annular block 1831 coaxially arranged with the driving rod 1811, and the upper end of the annular block 1831 is connected to the lower end surface of the rack sliding cavity 1815, and the inner side surface of the annular block 1831 is coaxially provided with an annular groove 1832, and the annular groove 1832 A stopper 1833 is provided inside, and the two ends of the stopper 1833 along the arc of the annular groove 1832 are respectively provided with a forward circuit contact piece 1834 and a reverse circuit contact piece 1835. The driving rod 1811 passes through the inner circle of the annular block 1831, and a reversing lever 1836 is provided on the driving rod 1811. The other end of the reversing lever 1836 extends to the inside of the annular groove 1832. The end of the reversing lever 1836 located inside the annular groove 1832 is provided with a contact 1837 that alternately contacts the forward circuit contact piece 1834 and the reverse circuit contact piece 1835, and a reset coil spring is also provided between the lower end of the annular block 1831 and the driving rod 1811. Fig.11 As shown, by the action of the reset coil spring, the contact 1837 contacts the positive circuit contact piece 1834 in the initial state. When the fire emergency lighting is detected, the contact 1837 and the positive circuit contact piece 1834 begin to be energized. When the electromagnet 1821 is energized, the second rack 1814 on the left side moves away and the second rack 1814 on the right side moves closer. The second rack 1814 on the left side moves leftward, causing the drive rod 1811 to rotate counterclockwise, thereby driving the contact 1837 to rotate counterclockwise. When the contact 1837 and the reverse When the circuit contact 1835 contacts, the magnetic field of the electromagnet 1821 will be converted, causing the second rack 1814 on the left to move closer and the second rack 1814 on the right to move away. The second rack 1814 on the left moves right, causing the drive rod 1811 to rotate clockwise, thereby driving the contact 1837 to rotate clockwise, causing the contact 1837 to contact the positive circuit contact 1834, and reciprocating in sequence, causing the two second racks 1814 to move left and right and reciprocate, causing the fan blades 1812 to rotate in a continuous cycle.
