Description

Technical Field

[0001] The present invention relates to the technical field of fire-fighting lighting fixtures, and in particular to an explosion-proof fire-fighting lighting fixture based on scene light control and glare prevention. Background Art

[0002] In the field of modern transportation system and emergency rescue, vehicle exterior lighting equipment plays a pivotal role, especially for fire trucks, lighting equipment is a key factor in the success of rescue operations and personnel safety. Fire trucks often need to perform tasks in various extreme environments, from the harsh conditions of thick smoke and flames at the fire scene to the complex road conditions on the way to rescue in the middle of the night. They are highly dependent on stable, reliable and efficient lighting systems. This requires not only that lighting equipment can provide firefighters with a clear view so that they can carry out rescue operations quickly and accurately, but also avoid causing interference to surrounding personnel and other rescue vehicles; However, existing vehicle exterior lighting equipment has exposed many serious drawbacks in firefighting scenarios, and the glare problem is particularly prominent. In the complex environment of strong light and thick smoke at the fire scene, or when fire trucks are driving at high speed to the rescue site at night, the glare generated by the lamps not only seriously hinders firefighters from seeing the surrounding environment clearly, affecting the accuracy and efficiency of rescue operations, but may also cause visual interference to nearby rescue personnel and vehicles, increasing rescue risks. Analysis of relevant fire accident cases shows that rescue errors or accidents caused by glare occur from time to time, bringing great challenges to firefighting and rescue work; The heat dissipation problem should not be ignored in the lighting of fire trucks. When fire trucks are performing tasks, the engines run at high load for a long time, which will generate a lot of heat. At the same time, the internal electronic components of the lamps will also generate heat during the continuous high-intensity lighting process. If the heat dissipation measures are not effective, the electronic components inside the lamps will be in a high temperature environment for a long time, which will not only accelerate the aging and damage of the components and greatly shorten the service life of the lamps. What is more serious is that electric sparks may be generated inside the lamps in a high temperature environment. For fire trucks, especially at the fire scene of flammable and explosive items, once the lamps cause a secondary explosion due to electric sparks, the consequences will be disastrous and will affect the life safety of rescuers and rescue operations. Summary of the invention

[0005] Preferably, a screw hole is provided at the lower end of the mounting seat, the sliding groove is arc-shaped, and the sliding groove and the rotating rod are concentrically arranged.

[0006] By adopting the above technical solution, the screw hole at the lower end of the mounting base facilitates the stable connection of the lamp with equipment such as fire trucks, and realizes quick installation and disassembly. The arc-shaped sliding groove concentric with the rotating rod, combined with the limit rod, can allow the lampshade to flexibly adjust the angle around the rotating rod, meeting the diverse needs of the lighting direction of the lamp in different rescue scenarios and enhancing the applicability of the lamp.

[0007] Preferably, the reflective plate is designed to be arc-shaped, and the reflective plates are distributed at equal angles on the inner surface of the lampshade, and the reflective plate and the lampshade are tightly fitted and rotatably connected.

[0008] By adopting the above technical solution, the arc-shaped reflective plate can better reflect and refract the light, and the equal angles distributed on the inner surface of the lampshade can realize all-round and multi-angle control of the light. The tight-fitting rotation connection method not only ensures the stability of the reflective plate during the rotation process, so that it can accurately change the angle, but also ensures that the reflective plate will not shake at will when the lamp vibrates, etc., effectively improving the anti-glare effect of the lamp in different scenes.

[0009] Preferably, the swivel and the lampshade are in a tight-fitting rotational connection, and the internal cavity of the swivel is connected to the piston cylinder, the piston cylinder and the piston rod are in a sliding friction connection, and a spring is connected between the piston cylinder and the piston rod, the fork rod is arranged opposite to the contact column, and the end of the fork rod opposite to the contact column is C-shaped.

[0010] By adopting the above technical scheme, the swivel and the lampshade are tightly fitted and rotatably connected, which ensures the stability of the swivel when rotating, so that it can accurately drive the piston cylinder to rotate. The internal cavity of the swivel is connected with the piston cylinder, which is convenient for pressure transmission, prompting the piston rod to slide in the piston cylinder. The spring between the piston cylinder and the piston rod plays a buffering and resetting role, ensuring the smooth operation of the mechanism. The facing setting of the fork rod and the contact column and the C-shaped design of the end of the fork rod facilitate the close engagement of the fork rod and the contact column, accurately driving the reflection plate to rotate, and realizing precise control of the refraction direction of light.

[0011] 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 of the movable magnet and the electromagnet facing each other are the same, and the movable magnet and the electromagnet are arranged in a one-to-one correspondence.

[0012] By adopting the above technical solution, the sliding friction connection between the piston plate and the swivel and the spring between the two enable the piston plate to slide smoothly in the swivel when the electromagnet is energized to generate a magnetic field. The movable magnet has the same magnetic pole as the electromagnet and is arranged one-to-one. By utilizing the principle of like poles repelling each other, the position of the piston plate can be accurately adjusted by controlling the on and off current of the electromagnet, thereby more accurately controlling the rotation of the swivel and achieving fine adjustment of the angle of the reflector to better meet the anti-glare needs in different scenarios.

[0013] Preferably, the tooth blocks are distributed at equal intervals on the inner surface of the rotating ring, and the rotating ring is meshedly connected with the transmission gear through the tooth blocks.

[0014] By adopting the above technical solution, the equally spaced distribution of the tooth blocks ensures the stability and transmission accuracy of the swivel during the process of meshing and rotating with the transmission gear. The swivel is meshed and connected with the transmission gear through the tooth blocks, so that when the switching motor drives the transmission gear to rotate, it can reliably drive the swivel to rotate, providing stable power transmission for the subsequent rotation of the reflector and adjustment of the refraction direction of light, ensuring the stable operation of the anti-glare function.

[0015] Preferably, the outer surface of the fan blade fits with the inner surface of the sealing tube, and the two ends of the sealing tube fit with the inner surface of the lampshade respectively.

[0016] By adopting the above technical solution, the fitting design of the fan blades and the sealing tube, as well as the fitting of the sealing tube and the lampshade, effectively avoids the leakage of air during the flow process and forms a relatively closed air circulation channel, which can improve the air flow efficiency and enable the external cold air inhaled by the fan blades to circulate more efficiently inside the lampshade, taking 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 a high temperature environment.

[0017] Preferably, the guide groove is annular in design, and the inner surface of the guide groove is fixedly connected to one end of the exhaust groove.

[0018] By adopting the above technical solution, the annular guide groove can evenly guide the air to flow in the lampshade, ensuring that the cold air can fully contact the heat-generating components inside the lamp and improve the uniformity of heat dissipation. The connection method between the exhaust groove and the guide groove allows the hot air after absorbing heat to smoothly enter the exhaust groove and be discharged from the lampshade through the exhaust groove, ensuring the smooth operation of the air circulation and cooling system and effectively improving the heat dissipation performance of the lamp.

[0019] Preferably, one end of the exhaust groove facing the outside of the lampshade passes through the outer surface of the lampshade, and one end of the connecting pipe passes through the inner surface of the sealing tube and the filter are respectively located on both sides of the fan blade.

[0020] With the above technical solution, the exhaust groove runs through the outer surface of the lampshade, providing a direct channel for the exhaust of hot air. The connecting pipe and the filter are respectively located on both sides of the fan blades, and with the rotation of the fan blades, a complete air circulation path is formed. Cold air is sucked in from one side of the filter, enters the lampshade through the connecting pipe, and is discharged from the exhaust groove after absorbing heat, thereby ensuring the efficiency and continuity of the heat dissipation process of the lamp, and further enhancing the explosion-proof performance of the lamp in high temperature environments.

[0021] Compared with the prior art, the beneficial effects of the present invention are: the explosion-proof fire-fighting lighting fixture based on scene light control and anti-glare: 1. The adjustment mechanism inside the lamp can effectively solve the glare problem. When the switching motor is started, its output shaft drives the transmission gear to rotate, and the tooth blocks evenly spaced on the inner surface of the swivel mesh with the transmission gear to rotate the swivel, and the piston cylinder on the outside of the swivel rotates accordingly. The piston rod slides relative to the piston cylinder under the pressure, and the fork rod engages with the contact column, and then drives the contact column to drive the reflector to rotate to change the angle of the reflector, and accurately control the direction of light refraction. In scenes such as strong light and thick smoke at the fire scene or fire trucks driving at high speed at night, glare is avoided to interfere with the firefighters' vision, allowing firefighters 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.

[0022] 2. The heat dissipation mechanism ensures the safe use of the lamp in a high temperature environment. The cooling motor is fixedly installed inside one end of the lampshade, and its output shaft drives the fan blades to rotate. When the fan blades rotate, external air is sucked into the lampshade and injected into the exhaust groove and the guide groove through the connecting pipe, so that the external cold air enters the lampshade through the filter to absorb heat and is finally discharged through the exhaust groove. This efficient air circulation can quickly dissipate the heat inside the lampshade, reduce the operating temperature of the electronic components inside the lamp, and reduce the possibility of electric sparks caused by high temperature, meeting the safety requirements of fire trucks at the scene of fires of flammable and explosive items. At the same time, good heat dissipation slows down the aging and damage of electronic components, prolongs the service life of electronic components such as LED light panels, and ensures the stable and reliable operation of the lamp in fire rescue missions.

[0023] 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 a first locking bolt. The lampshade 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 lampshade, is slidably connected to the sliding groove, and is fixed by a second locking bolt. The limiting rod is snap-fitted and installed with the lampshade. This structural design allows the lamp to flexibly adjust its angle to meet the requirements for lighting direction in different rescue scenarios and improve the applicability of the lamp.
