Abstract
Description
Technical Field
[0001] This invention relates to the field of fire-fighting lighting fixtures, specifically an explosion-proof fire-fighting lighting fixture based on scene-controlled light and anti-glare. Background Technology
[0002] In modern transportation systems and emergency rescue, vehicle external lighting equipment plays a crucial role, especially for fire trucks. Lighting equipment is a key factor in the success or failure of rescue operations and the safety of personnel. Fire trucks often need to perform tasks in various extreme environments, from the scorching smoke and flames at the scene of a fire to the complex road conditions on the way to a rescue at night. They are highly dependent on a stable, reliable and efficient lighting system. This not only requires the lighting equipment to provide firefighters with a clear vision so that they can carry out rescue operations quickly and accurately, but also to avoid interfering with surrounding personnel and other rescue vehicles.
[0003] However, existing vehicle external lighting equipment has revealed many serious drawbacks in firefighting scenarios, with glare being particularly prominent. In the complex environment of a fire scene where strong light and thick smoke are intertwined, or when fire trucks are traveling at high speeds to the rescue site at night, the glare generated by the lights not only seriously hinders firefighters from seeing the surrounding environment, affecting the accuracy and efficiency of rescue operations, but may also cause visual interference to nearby personnel and vehicles involved in the rescue, increasing the risk of rescue. Analysis of relevant fire accident cases shows that rescue errors or accidents caused by glare occur frequently, posing a great challenge to fire rescue work.
[0004] Heat dissipation is equally important for fire truck lights. When fire trucks are on duty, the engine runs under high load for extended periods, generating a large amount of heat. At the same time, the internal electronic components of the lights also generate heat during continuous high-intensity illumination. If heat dissipation measures are inadequate, the internal electronic components of the lights will be exposed to high temperatures for a long time, which will not only accelerate component aging and damage, significantly shortening the lifespan of the lights, but more seriously, the high temperature environment may generate electrical sparks inside the lights. For fire trucks, especially at fire scenes involving flammable and explosive materials, if the lights are ignited by electrical sparks and cause a secondary explosion, the consequences will be unimaginable, affecting the lives of rescue personnel and rescue operations. Summary of the Invention
[0005] The purpose of this invention is to provide an explosion-proof fire-fighting lighting fixture based on scene-controlled light and anti-glare, in order to solve the problems mentioned in the background art of easy glare generation and easy explosion under high temperature environment.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an explosion-proof fire-fighting lighting fixture based on scene-controlled light and anti-glare, comprising a mounting base, a rotating rod mounted on the upper end of the mounting base, the rotating rod being fixedly mounted to the mounting base by a first locking bolt, a rotating lampshade mounted on the outer surface of the rotating rod, a sliding groove being formed on the outer surface of the upper end of the mounting base, the sliding groove being penetrated by a limiting rod, and the limiting rod penetrating the lower end of the lampshade, the limiting rod being slidably connected to the sliding groove, and the limiting rod being fixedly mounted to the mounting base by a second locking bolt, and the limiting rod being engaged with the lampshade, a heat dissipation fin being fixedly provided on the outer surface of one end of the lampshade, an LED light board being fixedly mounted in the center of the inside of the lampshade, and an adjustment mechanism being provided on the inner surface of the lampshade, achieving an anti-glare effect by controlling the direction of light refraction in different scenes;
[0007] The adjustment mechanism includes: a reflector plate, which is rotatably mounted on the inner surface of the lampshade, and a contact post is fixedly provided on the outer surface of one end of the reflector plate; a rotating ring is installed inside the side surface of the lampshade, and a piston cylinder is fixedly provided on the outer surface of the rotating ring, and a sliding piston rod is installed inside the piston cylinder; a fork rod is fixedly connected to the end of the piston rod facing the outside of the piston cylinder; a cavity is opened inside the side surface of the rotating ring, and a sliding piston plate is installed inside the cavity of the side surface of the rotating ring, and a movable magnet is fixedly provided on the outer surface of the piston plate facing away from the piston cylinder; an electromagnet is fixedly installed inside the side surface of the lampshade; a toothed block is fixedly provided on the inner surface of the rotating ring; a switching motor is fixedly installed inside the side surface of the lampshade, and a transmission gear is fixedly connected to one end of the output shaft of the switching motor, and a clearance groove is opened on the inner surface of the lampshade facing the transmission gear;
[0008] The lampshade has a heat dissipation mechanism inside its outer surface. By rapidly dissipating the heat inside the lampshade, the possibility of electric sparks caused by high temperature is reduced, thereby achieving an explosion-proof effect.
[0009] The heat dissipation mechanism includes: a cooling motor, which is fixedly installed inside one end of the lampshade, and a fan blade is fixedly connected to one end of the output shaft of the cooling motor. A filter screen is installed on the outer surface of the lampshade facing the fan blade. A closed cylinder is fixedly installed inside the lampshade outside the fan blade. A guide groove is opened inside one side surface of the lampshade, and an exhaust groove is opened inside the side surface of the lampshade. A connector is fixedly connected to the uppermost exhaust groove facing the outside of the lampshade. A connecting pipe is fixedly connected to the connector facing the outside of the lampshade, and the other end of the connecting pipe penetrates the inner surface of the closed cylinder. A controller is installed inside the mounting base, and the controller is electrically connected to the switching motor and the cooling motor respectively through a wiring harness. The controller is also connected to an external control switch through a wiring harness.
[0010] Preferably, the lower end of the mounting base is provided with a screw hole, the sliding groove is arc-shaped, and the sliding groove and the rotating rod are concentrically arranged.
[0011] By adopting the above technical solution, the screw hole at the lower end of the mounting base facilitates a secure connection between the lamp and equipment such as fire trucks, enabling quick installation and disassembly. The arc-shaped sliding groove, concentric with the rotating rod, combined with the limiting rod, allows the lampshade to flexibly adjust its angle around the rotating rod, meeting the diverse lighting direction requirements of different rescue scenarios and enhancing the applicability of the lamp.
[0012] Preferably, the reflector is arc-shaped and is distributed at equal angles on the inner surface of the lampshade, and the reflector and the lampshade are tightly fitted and rotated together.
[0013] By adopting the above technical solution, the arc-shaped reflector can better reflect and refract light. The reflector is evenly distributed on the inner surface of the lampshade, which can realize the all-round and multi-angle control of light. The tight-fitting rotating connection method not only ensures the stability of the reflector during the rotation process, allowing it to change the angle precisely, but also ensures that the reflector will not shake randomly under the vibration of the lamp, effectively improving the anti-glare effect of the lamp in different scenarios.
[0014] Preferably, the rotating ring and the lamp cover are tightly fitted and rotated, and the internal cavity of the rotating ring is connected to the piston cylinder. The piston cylinder and the piston rod are connected by sliding friction, and a spring is connected between the piston cylinder and the piston rod. The fork is positioned directly opposite the contact post, and the end of the fork facing the contact post has a C-shaped design.
[0015] The above technical solution features a tightly fitted rotating connection between the rotating ring and the lampshade, ensuring the stability of the rotating ring during rotation and enabling it to precisely drive the piston cylinder to rotate. The internal cavity of the rotating ring is connected to the piston cylinder, facilitating pressure transmission and causing the piston rod to slide within the piston cylinder. The spring between the piston cylinder and the piston rod acts as a buffer and reset mechanism, ensuring smooth operation. The aligned arrangement of the fork and the contact post, along with the C-shaped design at the end of the fork, facilitates a tight engagement between the fork and the contact post, precisely driving the reflector to rotate and achieving precise control over the direction of light refraction.
[0016] Preferably, the piston plate and the rotating ring are connected by sliding friction, and a spring is connected between the piston plate and the rotating ring. The magnetic poles at the opposite ends of the movable magnet and the electromagnet are the same, and the movable magnet and the electromagnet are arranged in a one-to-one correspondence.
[0017] By adopting the above technical solution, the sliding friction connection between the piston plate and the rotating ring, and the spring between them, allows the piston plate to slide smoothly within the rotating ring when the electromagnet is energized to generate a magnetic field. The movable magnet and the electromagnet have the same magnetic poles and are set in a one-to-one correspondence. Utilizing the principle of like poles repelling, the position of the piston plate can be precisely adjusted by controlling the current flow of the electromagnet, thereby more accurately controlling the rotation of the rotating ring and achieving fine adjustment of the reflector angle to better adapt to the anti-glare requirements in different scenarios.
[0018] Preferably, the tooth blocks are evenly distributed on the inner surface of the rotating ring, and the rotating ring is connected to the transmission gear through the tooth blocks.
[0019] By adopting the above technical solution, the evenly spaced distribution of the tooth blocks ensures the smoothness and transmission accuracy of the rotating ring during its meshing rotation with the transmission gear. The rotating ring is connected to the transmission gear through the tooth blocks, so that when the switching motor drives the transmission gear to rotate, it can reliably drive the rotating ring to rotate, providing a stable power transmission for subsequently driving the reflector to rotate and adjusting the direction of light refraction, thus ensuring the stable operation of the anti-glare function.
[0020] Preferably, the outer surface of the fan blade is in contact with the inner surface of the closed cylinder, and both ends of the closed cylinder are in contact with the inner surface of the lampshade.
[0021] By adopting the above technical solution, the fitting design of the fan blade and the sealed cylinder, as well as the fitting of the sealed cylinder and the lamp cover, effectively avoids air leakage during the flow process, forming a relatively closed air circulation channel. This can improve air flow efficiency, allowing the external cold air drawn in by the fan blade to circulate more efficiently inside the lamp cover, carrying away the heat generated by the lamp, enhancing the heat dissipation effect of the lamp, reducing the internal temperature of the lamp, and ensuring the safe and stable operation of the lamp in high-temperature environments.
[0022] Preferably, the guide channel is annular in design, and the inner surface of the guide channel is fixedly connected to one end of the exhaust channel.
[0023] By adopting the above technical solution, the annular design of the air guide groove can guide the air to flow evenly inside the lamp cover, ensuring that the cold air can fully contact the heat-generating components inside the lamp and improve the uniformity of heat dissipation. The connection between the exhaust groove and the air guide groove allows the hot air that has absorbed heat to smoothly enter the exhaust groove and be discharged from the lamp cover through the exhaust groove, ensuring the smooth operation of the air circulation heat dissipation system and effectively improving the heat dissipation performance of the lamp.
[0024] Preferably, the end of the exhaust groove facing the outside of the lampshade penetrates the outer surface of the lampshade, and the end of the connecting pipe penetrating the inner surface of the closed cylinder and the filter screen are respectively located on both sides of the fan blade.
[0025] With the above technical solution, the exhaust groove runs through the outer surface of the lampshade, providing a direct channel for hot air to be discharged. The layout of the connecting pipe and the filter screen located on both sides of the fan blades, together with the rotation of the fan blades, forms a complete air circulation path. Cold air is drawn in from the filter screen side, enters the lampshade through the connecting pipe, and is discharged from the exhaust groove after absorbing heat. This ensures the high efficiency and continuity of the lamp's heat dissipation process and further enhances the lamp's explosion-proof performance in high-temperature environments.
[0026] Compared with the prior art, the beneficial effects of the present invention are: the explosion-proof fire-fighting lighting fixture based on scene-controlled light and anti-glare:
[0027] 1. The internal adjustment mechanism of the lamp effectively solves the glare problem. When the switching motor starts, its output shaft drives the transmission gear to rotate. The teeth blocks evenly distributed on the inner surface of the rotating ring mesh with the transmission gear, causing the rotating ring to rotate. The piston cylinder on the outer side of the rotating ring rotates accordingly. Under pressure, the piston rod slides relative to the piston cylinder, and the fork engages with the contact post. This, in turn, drives the reflector to rotate by the contact post, changing the angle of the reflector and precisely controlling the direction of light refraction. In scenarios such as strong light and thick smoke at fire scenes or fire trucks traveling at high speeds at night, glare avoids interfering with the firefighters' vision, allowing them to clearly see the surrounding environment, improving the accuracy and efficiency of rescue operations, while preventing visual interference to nearby rescue personnel and vehicles, and reducing rescue risks.
[0028] 2. The heat dissipation mechanism ensures the safe use of the lamp in high-temperature environments. The cooling motor is fixedly installed inside one end of the lamp cover. Its output shaft drives the fan blades to rotate. When the fan blades rotate, they draw in outside air into the lamp cover and inject it into the exhaust groove and guide groove through the connecting pipe. This allows the outside cold air to enter the lamp cover through the filter, absorb heat, and finally be discharged through the exhaust groove. This efficient air circulation can quickly dissipate the heat inside the lamp cover, reduce the operating temperature of the electronic components inside the lamp, reduce the possibility of electrical sparks caused by high temperatures, and meet the safety requirements of fire trucks at fire scenes involving flammable and explosive materials. At the same time, good heat dissipation slows down the aging and damage rate of electronic components, extends the service life of LED light boards and other electronic components, and ensures the stable and reliable operation of the lamp in fire rescue missions.
[0029] 3. A screw hole is provided at the lower end of the mounting base to facilitate the installation of the lamp on fire trucks and other equipment. The rotating rod is installed at the upper end of the mounting base and fixed by the first locking bolt. The lamp cover is rotatably connected to the rotating rod. The limiting rod passes through the arc-shaped sliding groove on the mounting base and the lower end of the lamp cover, and is slidably connected with the sliding groove and fixed by the second locking bolt. The limiting rod is engaged with the lamp cover. This structural design allows the lamp to be flexibly adjusted in angle to meet the lighting direction requirements in different rescue scenarios and improve the applicability of the lamp.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.
[0043] Please see Figures 1-11 The present invention provides a technical solution: an explosion-proof fire-fighting lighting fixture based on scene-controlled light and anti-glare.
[0044] Example 1: This example discloses a mounting base 1. A rotating rod 2 is mounted on the upper end of the mounting base 1, and the rotating rod 2 is fixedly mounted to the mounting base 1 by a first locking bolt 3. A rotating lampshade 4 is mounted on the outer surface of the rotating rod 2. A sliding groove 5 is opened on the outer surface of the upper end of the mounting base 1, and the sliding groove 5 is penetrated by a limiting rod 6. The limiting rod 6 penetrates the lower end of the lampshade 4, and the limiting rod 6 is slidably connected to the sliding groove 5. The limiting rod 6 is fixedly mounted to the mounting base 1 by a second locking bolt 7, and the limiting rod 6 is engaged with the lampshade 4. A heat dissipation fin 8 is fixedly provided on the outer surface of one end of the lampshade 4. An LED light board 9 is fixedly installed in the center of the inside of the lampshade 4, and an adjustment mechanism is provided on the inner surface of the lampshade 4. The anti-glare effect is achieved by controlling the direction of light refraction in different scenarios.
[0045] The adjustment mechanism includes: a reflector 10, which is rotatably mounted on the inner surface of the lampshade 4, and a contact post 11 is fixedly provided on the outer surface of one end of the reflector 10; a rotating ring 12 is installed inside the side surface of the lampshade 4, and a piston cylinder 13 is fixedly provided on the outer surface of the rotating ring 12; a sliding piston rod 14 is installed inside the piston cylinder 13, and a fork rod 15 is fixedly connected to the end of the piston rod 14 facing the outside of the piston cylinder 13; a cavity is opened inside the side surface of the rotating ring 12, and the rotating ring 12... A sliding piston plate 16 is installed inside the cavity of the two side surfaces, and a movable magnet 17 is fixedly installed on the outer surface of the piston plate 16 facing away from the piston cylinder 13. An electromagnet 18 is fixedly installed inside the side surface of the lamp cover 4. A toothed block 19 is fixedly installed on the inner side surface of the rotating ring 12. A switching motor 20 is fixedly installed inside the side surface of the lamp cover 4, and a transmission gear 21 is fixedly connected to one end of the output shaft of the switching motor 20. A clearance groove 22 is opened on the inner side surface of the lamp cover 4 opposite to the transmission gear 21.
[0046] The lower end of the mounting base 1 is provided with a screw hole, the sliding groove 5 is arc-shaped, and the sliding groove 5 and the rotating rod 2 are concentrically set;
[0047] The reflector 10 has an arc-shaped design and is distributed at equal angles on the inner surface of the lamp cover 4. The reflector 10 and the lamp cover 4 are connected by a tight-fitting rotatable connection.
[0048] The rotating ring 12 and the lamp cover 4 are tightly fitted and rotated, and the internal cavity of the rotating ring 12 is connected to the piston cylinder 13. The piston cylinder 13 and the piston rod 14 are connected by sliding friction, and a spring is connected between the piston cylinder 13 and the piston rod 14. The fork rod 15 is set directly opposite the contact post 11, and the end of the fork rod 15 facing the contact post 11 is designed in a C shape.
[0049] The piston plate 16 and the rotating ring 12 are connected by sliding friction, and a spring is connected between the piston plate 16 and the rotating ring 12. The magnetic poles of the movable magnet 17 and the electromagnet 18 are the same at opposite ends, and the movable magnet 17 and the electromagnet 18 are set in a one-to-one correspondence.
[0050] The toothed blocks 19 are evenly distributed on the inner surface of the rotating ring 12, and the rotating ring 12 is meshed with the transmission gear 21 through the toothed blocks 19.
[0051] The screw hole at the lower end of the mounting base 1 is used to install the lamp on fire trucks and other equipment. The rotating rod 2 is installed on the upper end of the mounting base 1 and fixed by the first locking bolt 3. The lamp cover 4 is rotatably connected to the rotating rod 2. The limiting rod 6 passes through the arc-shaped sliding groove 5 on the mounting base 1 and the lower end of the lamp cover 4, and is slidably connected to the sliding groove 5. It is fixed by the second locking bolt 7. This structural design allows the lamp to be adjusted according to different rescue scenarios. After loosening the second locking bolt 7, the limiting rod 6 slides along the sliding groove 5, which drives the lamp cover 4 to rotate and adjust to a suitable lighting angle. Then, the second locking bolt 7 is tightened to fix it, which improves the applicability of the lamp. The heat dissipation fins 8 play a role in assisting the heat dissipation of the lamp cover 4 when the LED light board 9 is working.
[0052] When the light fixture needs to adjust the direction of light refraction to prevent glare, the controller 31 controls the switching motor 20 to start. Its output shaft drives the transmission gear 21 to rotate. The teeth 19, which are evenly spaced on the inner surface of the rotating ring 12, mesh with the transmission gear 21, causing the rotating ring 12 to rotate. The clearance groove 22 avoids the teeth 19 to ensure the normal rotation of the rotating ring 12. The piston cylinder 13 on the outer side of the rotating ring 12 rotates accordingly. At this time, the electromagnet 18 in the appropriate position is activated to generate a repulsive force on the movable magnet 17, causing the piston plate 16 to slide and drive the piston rod 14 inside the piston cylinder 13 through pressure. The spring acts as a buffer and reset mechanism. The fork 15 at the end of the piston rod 14 engages with the contact post 11 at one end of the reflector 10, thereby driving the reflector 10 to rotate. The reflector 10 is arc-shaped and evenly distributed on the inner surface of the lamp cover 4, tightly fitted and rotatably connected to the lamp cover 4. By changing the angle of the reflector 10, the direction of light refraction can be precisely controlled. In scenarios such as strong light and thick smoke at the fire scene or fire trucks traveling at high speed at night, glare can be avoided to prevent interference with the firefighters' vision, improve the accuracy and efficiency of rescue operations, and prevent visual interference to nearby rescue personnel and vehicles.
[0053] Example 2: Based on Example 1, this example discloses that a heat dissipation mechanism is provided inside the outer surface of the lampshade 4. By rapidly dissipating the heat inside the lampshade 4, the possibility of electric sparks caused by high temperature is reduced, thereby achieving the effect of explosion prevention.
[0054] The heat dissipation mechanism includes: a cooling motor 23, which is fixedly installed inside one end of the lamp cover 4, and a fan blade 24 is fixedly connected to one end of the output shaft of the cooling motor 23. A filter screen 25 is installed on the outer surface of the lamp cover 4 facing the fan blade 24. A closed cylinder 26 is fixedly installed inside the lamp cover 4 outside the fan blade 24. A guide groove 27 is opened inside the side surface of one end of the lamp cover 4, and an exhaust groove 28 is opened inside the side surface of the lamp cover 4. A connector 29 is fixedly connected to the uppermost exhaust groove 28 facing the outside of the lamp cover 4. A connecting pipe 30 is fixedly connected to the end of the connector 29 facing the outside of the lamp cover 4, and the other end of the connecting pipe 30 passes through the inner surface of the closed cylinder 26. A controller 31 is installed inside the mounting base 1. The controller 31 is electrically connected to the switching motor 20 and the cooling motor 23 through a wiring harness, and the controller 31 is connected to an external control switch through a wiring harness.
[0055] The outer surface of the fan blade 24 is in contact with the inner surface of the closed cylinder 26, and both ends of the closed cylinder 26 are in contact with the inner surface of the lamp cover 4 respectively.
[0056] The guide channel 27 is annular, and the inner surface of the guide channel 27 is fixedly connected to one end of the exhaust channel 28.
[0057] The exhaust groove 28 extends through the outer surface of the lamp cover 4 at one end, and the connecting pipe 30 extends through the inner surface of the closed cylinder 26 at one end. The filter screen 25 is located on both sides of the fan blade 24.
[0058] The cooling motor 23 is fixedly installed inside one end of the lampshade 4. After the cooling motor 23 is started by the controller 31, its output shaft drives the fan blade 24 to rotate. When the fan blade 24 rotates, it draws outside air into the lampshade 4 through the filter 25. The filter 25 prevents dust and other impurities from entering the lamp, ensuring the cleanliness of the lamp's interior. After air is drawn in, it is injected into the exhaust groove 28 and the guide groove 27 through the connecting pipe 30 and the connector 29. The guide groove 27 has a ring-shaped design and is evenly distributed inside the side surface of one end of the lampshade 4, guiding the air to flow evenly within the lampshade 4 and fully absorbing the heat inside the lamp. The outer surface of the fan blade 24 is in contact with the inner surface of the enclosed cylinder 26. The structural design allows air to be drawn in and output under pressure through the connecting pipe 30, improving airflow efficiency. The hot air, after absorbing heat, is finally discharged from the lamp cover 4 through the exhaust slot 28, forming a complete air circulation path. This efficient air circulation can quickly dissipate the heat inside the lamp cover 4, reduce the operating temperature of the electronic components inside the lamp, reduce the possibility of electrical sparks caused by high temperatures, and meet the safety requirements of fire trucks at fire scenes involving flammable and explosive materials. At the same time, good heat dissipation slows down the aging and damage rate of electronic components, extends the service life of electronic components such as the LED light board 9, and ensures the stable and reliable operation of the lamp in fire rescue missions.

It should be understood that the above are merely specific embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention are included within the protection scope of the present invention.
