Description

Technical Field

[0001] This invention relates to the field of lighting device technology, and specifically to an energy-saving explosion-proof lighting device for subways. Background Technology

[0002] In modern subway construction and operation, the importance of lighting systems is self-evident, as their stable operation directly affects passenger safety and comfort. Traditional subway lighting largely relies solely on mains power, a power supply model with numerous drawbacks. Firstly, the continuous and substantial consumption of mains power results in energy costs accounting for a significant portion of subway operating costs, becoming a heavy economic burden over the long term. Secondly, mains power supply is susceptible to interference from various factors, such as grid failures caused by severe weather and power shortages during peak hours. Once mains power fails, subway lighting interruptions will severely threaten passenger safety and the order of subway operations.

[0003] At the same time, subway trains create strong and continuous airflow as they travel at high speeds. This airflow contains considerable energy, but in previous subway facility designs, this energy resource has been neglected and not effectively developed or utilized, resulting in a huge waste of energy.

[0004] Therefore, an energy-saving explosion-proof lighting device for subways is proposed. Summary of the Invention

[0005] This invention provides an energy-saving explosion-proof lighting device for subways to solve the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

One power connection mechanism is connected to the mains power, and the other power connection mechanism is connected to the storage battery.

[0009] Furthermore, the charging controller is internally equipped with a charging module, a power detection module, a disconnection module, and a power connection control module. The charging module is used to transmit the electrical energy generated by the power generation component to the storage battery for storage. The power detection module is used to detect the percentage of power in the storage battery. The disconnection module is used to control the operation of the connection mechanism. The power connection control module is used to control the operation of the power connection mechanism.

[0010] Furthermore, the power detection module includes a first detection unit, a second detection unit, and a third detection unit. The first detection unit and the second detection unit are both connected to the disconnection module, and the first detection unit and the third detection unit are both connected to the power connection control module.

[0011] Furthermore, the power connection control module includes a first power connection unit and a second power connection unit, which are respectively connected to the corresponding power connection mechanism.

[0012] Furthermore, the rotating assembly includes a rotating shaft, fan blades, and a first bevel gear. The rotating shaft is rotatably installed inside the light box, and multiple fan blades are provided on the rotating shaft. The top end of the rotating shaft is located inside a fixed box, and the first bevel gear, which meshes with the transmission assembly, is installed at that end.

[0013] Furthermore, the transmission assembly includes a support base, a transmission shaft, a second bevel gear, and a connecting groove. The support base is installed inside a fixed box, and the transmission shaft is rotatably mounted on the support base. One end of the transmission shaft is equipped with a second bevel gear that meshes with the first bevel gear, and the other end of the transmission shaft has a connecting groove.

[0014] Furthermore, the power generation component includes a generator body, an input shaft, and a slot. The generator body is provided with an input shaft, and the input shaft has a slot.

[0015] Furthermore, the connecting mechanism includes a first slide rail, a movable frame, a connecting shaft, a connecting end, a plug, and a first electric actuator. There are two first slide rails, which are installed parallel to each other on one side of the support base. The top ends of the two first slide rails jointly support a slidably installed movable frame. A connecting shaft is rotatably installed on the movable frame. One end of the connecting shaft is provided with a connecting end, and the other end of the connecting shaft is provided with a plug.

[0018] The embodiments of the present invention have the following advantages:

[0019] 1. The airflow generated by the subway operation drives the rotating component to rotate, which in turn drives the power generation component to work through the transmission component. The wind energy is converted into electrical energy and stored in the battery to power the explosion-proof lighting. This effectively reduces the consumption of mains electricity, greatly improves energy utilization efficiency, and achieves the goal of energy saving.

[0020] 2. Through the settings of the charging controller, its internal power detection module can monitor the power of the storage battery in real time. When the battery is fully charged, it can control the connection mechanism to disconnect the transmission component from the power generation component through the disconnection module to prevent overcharging and damage to the battery. As the power is consumed, it can reconnect when the power is appropriate to continue generating electricity. At the same time, according to the power status of the storage battery, the power connection control module can automatically switch between mains power or storage battery to power the explosion-proof lighting, ensuring continuous lighting and energy saving.

[0021] 3. During the process of driving the power generation, the airflow enters the air ducts on both sides of the explosion-proof lighting lamp, carrying away the heat generated by the explosion-proof lighting lamp, realizing the heat dissipation function, ensuring the stable operation of the explosion-proof lighting lamp, avoiding damage due to overheating, extending the service life of the explosion-proof lighting lamp, and improving the power generation efficiency and power output.

[0035] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Refer to the instruction manual appendix Figures 1-10 As shown, an energy-saving explosion-proof subway lighting device includes a fixed box 1, a top cover 2 installed on the top of the fixed box 1, a mains power interface 9 on one side of the fixed box 1, a light box 3 installed at the bottom of the fixed box 1, a base plate 4 installed at the bottom of the light box 3, an explosion-proof lighting lamp 5 installed in the middle of the bottom of the light box 3, air inlets 6 on both sides of the light box 3, a rotating component 7 installed inside each air inlet 6, air ducts 8 formed on both sides of the explosion-proof lighting lamp 5, and the two air inlets 6 are connected by the air ducts 8, a transmission component 10 installed in the fixed box 1 is engaged at the top of each rotating component 7, a power generation component 11 is installed on one side of each transmission component 10, a connecting mechanism 12 is provided between each transmission component 10 and the power generation component 11, a storage battery 15 is installed in the fixed box 1, the storage battery 15 is connected to two charging controllers 14, each charging controller 14 is connected to a rectifier 13, and each rectifier 13 is connected to the corresponding power generation component 11.

[0037] A mounting base 16 is installed in the middle of the fixed box 1. A lighting electrode 17 connected to the explosion-proof lighting lamp 5 is installed on the mounting base 16. A power connection mechanism 18 is provided on both sides of the mounting base 16. One power connection mechanism 18 is connected to the mains power, and the other power connection mechanism 18 is connected to the storage battery 15.

[0038] In practice, the fixed box 1 is fixed above the subway passage, and a power connection mechanism 18 is connected to the mains power. When a subway train passes through the subway passage, a huge airflow is generated, which enters the light box 3 from the air inlet 6 and exits from the other air inlet 6 through the air duct 8. During the process of the high-speed airflow entering, the two rotating components 7 rotate respectively, so that the corresponding transmission component 10, under the connection of the connecting mechanism 12, makes the power generation component 11 work, converting wind energy into electrical energy. Under the rectification of the rectifier 13, the AC power is converted into DC power and transmitted to the charging controller 14 and then stored in the storage battery 15 for use in the explosion-proof lighting lamp 5, thereby improving the energy-saving effect of the explosion-proof lighting lamp 5 and reducing the mains power consumption of the explosion-proof lighting lamp 5.

[0039] The charging controller 14 detects the charging status of the battery 15. After the battery 15 is fully charged, it controls the operation of each connecting mechanism 12, thereby disconnecting the connection between the transmission component 10 and the power generation component 11 to prevent overcharging and damage to the battery 15. At the same time, it stops the power generation component 11 from working, which can effectively reduce the rotational wear of the input shaft 1102 of the power generation component 11, improve its service life, and reduce the maintenance frequency. The two connecting mechanisms 18 are also controlled by the charging controller 14. When the battery 15 has a charge level above the set value, the connecting mechanism 18 connected to the battery 15 is controlled to connect to the lighting connecting electrode 17 so that the battery 15 can provide power support for the explosion-proof lighting lamp 5. When the battery 15 has a charge level below the set value, the connecting mechanism 18 connected to the mains power is connected to the lighting connecting electrode 17 to ensure the continuous lighting of the explosion-proof lighting lamp 5, thereby reducing the use of mains power and improving energy saving.

[0040] The charging controller 14 is internally equipped with a charging module, a power detection module, a disconnection module, and a power connection control module. The charging module is used to transfer the electrical energy generated by the power generation component 11 to the storage battery 15 for storage. The power detection module is used to detect the percentage of power in the storage battery 15. The disconnection module is used to control the operation of the connection mechanism 12. The power connection control module is used to control the operation of the power connection mechanism 18.

[0041] The power detection module includes a first detection unit, a second detection unit, and a third detection unit. Both the first and second detection units are connected to the disconnection module, and both the first and third detection units are connected to the power connection control module.

[0042] The power connection control module includes a first power connection unit and a second power connection unit, which are respectively connected to the corresponding power connection mechanism 18.

[0043] In practice, the electrical energy rectified by rectifier 13 enters the charging controller 14, where the charging module stores it in the storage battery 15. During charging, the power detection module monitors the energy in the storage battery 15 in real time. When the first detection unit detects that the battery is 100% saturated, it sends a feedback signal to the connecting mechanism 12, causing the two connecting mechanisms 12 to disconnect the corresponding transmission component 10 from the power generation component 11, thus preventing excessive current from damaging the storage battery 15. As the storage battery 15 supplies power to the explosion-proof lighting 5, the power level in the storage battery 15 decreases. When the second detection unit detects that the power level in the storage battery 15 is below 80%, it sends a feedback signal to the connecting mechanism 12, causing the two connecting mechanisms 12 to operate and reconnect the transmission component 10 to the power generation component 11, continuing to generate electricity using the airflow generated by the subway passing through the subway tunnel. When the explosion-proof lighting 5 consumes too much power and the power generation component 11 cannot supply enough power, the power level in the storage battery 15 continues to decrease. When the third detection unit detects that the charge level in the storage battery 15 is less than 20%, a feedback signal is sent to the power connection control module. The second power connection unit within the power connection control module then controls the power connection mechanism 18 connected to the mains power, connecting the mains power to the explosion-proof lighting lamp 5. Simultaneously, the first power connection unit controls the power connection mechanism 18 connected to the storage battery 15 to disconnect from the lighting power connection electrode 17, thus continuing to store power. When the first detection unit detects that the charge level in the storage battery 15 reaches 100%, a feedback signal is sent to the power connection control module. This causes the first power connection unit to control the power connection mechanism 18 connected to the storage battery 15 to connect to the lighting power connection electrode 17, while the second power connection unit controls the power connection mechanism 18 connected to the mains power to disconnect from the lighting power connection electrode 17, continuing to supply power to the storage battery 15. This greatly utilizes the charge level in the storage battery 15, reduces the use of mains power, and improves energy efficiency.

[0044] The rotating assembly 7 includes a rotating shaft 701, a fan blade 702, and a first bevel gear 703. The rotating shaft 701 is rotatably installed inside the light box 3. Multiple fan blades 702 are provided on the rotating shaft 701. The top end of the rotating shaft 701 is located inside the fixed box 1, and the first bevel gear 703, which meshes with the transmission assembly 10, is installed at this end.

[0045] The transmission assembly 10 includes a support base 1001, a transmission shaft 1002, a second bevel gear 1003, and a connecting groove 1004. The support base 1001 is installed in the fixed box 1. The transmission shaft 1002 is rotatably mounted on the support base 1001. One end of the transmission shaft 1002 is equipped with a second bevel gear 1003 that meshes with the first bevel gear 703. The other end of the transmission shaft 1002 is provided with a connecting groove 1004.

[0046] The power generation component 11 includes a generator body 1101, an input shaft 1102, and a slot 1103. The generator body 1101 is provided with an input shaft 1102, and the input shaft 1102 is provided with a slot 1103.

[0047] The connecting mechanism 12 includes a first slide rail 1201, a movable frame 1202, a connecting shaft 1203, a connecting end 1204, a plug 1205, and a first electric push rod 1206. There are two first slide rails 1201, which are installed in parallel on one side of the support base 1001. The top ends of the two first slide rails 1201 jointly support the movable frame 1202, which is rotatably mounted on the movable frame 1202. One end of the connecting shaft 1203 is provided with a connecting end 1204, and the other end of the connecting shaft 1203 is provided with a plug 1205. Two first electric push rods 1206 are symmetrically connected to one side of the bottom end of the movable frame 1202.

[0048] The connector 1204 is inserted into the connector slot 1004, and the plug 1205 is inserted into the slot 1103.

[0049] In practice, when the subway passes through the subway tunnel, a high-speed airflow is generated and enters through an air inlet 6. Since the air inlet 6 is biased to one side of the rotating shaft 701, the fan blade 702, which is directly blown by the airflow, is driven by the wind force, causing the rotating shaft 701 to rotate. This causes the first bevel gear 703 to mesh with the second bevel gear 1003 and rotate. Under the transmission of the drive shaft 1002, the connecting end 1204 inserted in the connecting slot 1004 drives the connecting shaft 1203 to rotate. This causes the connecting end 1204, which is inserted in the slot 1103, to drive the input shaft 1102 to rotate, thereby triggering the generator body 1101 to generate electricity by cutting magnetic field lines. Under the rectification of rectifier 13 and the transmission of charge controller 14, the electrical energy generated by the generator is stored in the storage battery 15. The airflow after driving the rotating component 7 to rotate enters the air ducts 8 on both sides of the explosion-proof lighting lamp 5, thereby absorbing the heat generated by the explosion-proof lighting lamp 5. After blowing on another rotating component 7, the heat is discharged from another air inlet 6. This can greatly utilize the kinetic energy of airflow to convert into electrical energy, improve the power generation efficiency and output, and dissipate heat from the explosion-proof lighting lamp 5, ensuring the stable operation of the explosion-proof lighting lamp 5 and preventing it from burning out due to excessive temperature during continuous operation. This can improve the service life of the explosion-proof lighting lamp 5, reduce the use of mains power, and improve energy saving.

[0050] The extension and retraction of the first electric push rod 1206 allows the movable frame 1202 to move on the two first slide rails 1201, thereby adjusting the positions of the connecting ends 1204 and plug 1205 at both ends of the connecting shaft 1203. When the two first electric push rods 1206 retract, the plug 1205 continues to be inserted into the slot 1103, while the connecting end 1204 is removed from the connecting groove 1004. Thus, after the battery 15 is fully charged, the connection between the power generation component 11 and the transmission component 10 is disconnected, causing the power generation component 11 to stop working and thus stop generating electricity. This improves the protection of the generator body 1101 and extends its service life. When power generation is needed, the connecting end 1204 is reinserted into the connecting groove 1004, allowing the power generation component 11 to continue operating and generating electricity.

[0051] The power connection mechanism 18 includes a second slide rail 1801, a slide plate 1802, an insulating seat 1803, a power connection terminal 1804, and a second electric push rod 1805. There are two second slide rails 1801, and the tops of the two second slide rails 1801 jointly support the slide plate 1802 which is slidably installed. The insulating seat 1803 is installed on the top of the slide plate 1802, and the power connection terminal 1804 is installed on the insulating seat 1803. The second electric push rod 1805 is symmetrically installed on one side of the slide plate 1802.

[0052] In practice, the extension and retraction of the second electric push rod 1805 causes the slide plate 1802 to move on the second slide rail 1801, thereby adjusting the electrical terminal 1804 installed on the insulating base 1803 to move closer to or further away from the lighting electrical electrode 17. This allows control over the connection or disconnection between the electrical terminal 1804 and the lighting electrical electrode 17. When the electrical terminal 1804 connected to the storage battery 15 is connected to the lighting electrical electrode 17, the storage battery 15 can provide power to the explosion-proof lighting lamp 5. When the electrical terminal 1804 connected to the mains power is connected to the lighting electrode 17, the explosion-proof lighting lamp 5 is powered by the mains power. This allows for automatic adjustment of the power supply mode, enabling the use of electrical energy converted from the kinetic energy generated by the passing subway to power the explosion-proof lighting lamp 5, reducing the mains power consumption of the explosion-proof lighting lamp 5, and thus saving energy.

[0053] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.

[0054] The terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.
