Description

Technical Field

[0001] This invention relates to the field of explosion-proof lighting technology, and in particular to an installation method, device, and explosion-proof lighting fixture. Background Technology

[0002] Explosion-proof lighting fixtures are used in environments containing flammable and explosive materials and are key infrastructure for safe production in industries such as petroleum and chemical manufacturing. The core design requirement of explosion-proof lighting fixtures is to prevent sparks and high temperatures from igniting the external environment in the event of an internal failure. Current installation and replacement of explosion-proof lighting fixtures employs traditional manual procedures: threading cables, stripping wire cores, securing the wire cores to the terminals, aligning the lighting fixture with the mounting base, and tightening multiple heavy-duty explosion-proof bolts to ensure the explosion-proof rating.

[0003] This traditional method has many drawbacks: First, manual electrical wiring poses a safety hazard of generating electric sparks in flammable and explosive environments; second, the installation process is cumbersome and time-consuming, requiring personnel to tighten bolts at heights or in confined spaces, which is physically demanding and prolongs the high-risk operation time; third, the reliance on manual operation leads to uncertain installation quality, as the bolt torque and the compaction of the sealing ring depend on the experience and sense of responsibility of the personnel, and negligence can cause the explosion-proof performance and connection stability to fail, leaving long-term safety hazards.

[0048] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. 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 should fall within the scope of protection of the present invention.

[0049] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0050] Figure 1 This is a structural schematic diagram of an explosion-proof lighting fixture provided in an embodiment of the present invention. Figure 2This is a flowchart illustrating an installation method for explosion-proof lighting fixtures according to an embodiment of the present invention. This embodiment is applicable to the installation of explosion-proof lighting fixtures. The method can be executed by an installation device for the explosion-proof lighting fixture, which can be implemented in hardware and / or software and can be configured within the explosion-proof lighting fixture.

[0051] refer to Figure 1 The explosion-proof lighting fixture includes a mounting base 110 and an explosion-proof lamp body 120. The mounting base 110 is pre-set at a fixed position. The mounting base 110 is provided with a guiding and adsorption unit 111, a locking and sensing unit 112, and an energy and control unit 113. The guiding and adsorption unit 111 includes a guide groove provided on the mating surface of the mounting base 110, and a preset number of permanent magnets are arranged in an array in the guide groove. The energy and control unit 113 includes a controller. The explosion-proof lamp body 120 is completely sealed. The back of the explosion-proof lamp body 120 includes a mating boss that matches the shape and size of the guide groove. Soft iron material is embedded in the mating boss at the position corresponding to the permanent magnet.

[0052] For example, the mounting base 110 can be a pre-installed, permanently sealed unit mounted on a wall, bracket, or other fixed structure. Its housing can be made of high-strength metal and designed according to strict explosion-proof standards, ensuring complete isolation of all internal electronic components from the external hazardous environment. The guiding and adsorption unit 111 can be a V-shaped guide groove on the mating surface of the mounting base. The geometry of this guide groove is precisely calculated, and its inclined sidewalls provide a clear mechanical guiding path when the explosion-proof lamp body 120 approaches. At the bottom and sides of the V-shaped guide groove, several high-field-strength permanent magnets, such as neodymium iron boron (NdFeB) permanent magnets, are embedded in an array. The polarities of these permanent magnets are specially arranged to form a specific strong magnetic field region in front of the mounting base. This magnetic field not only generates a strong normal adsorption force but also works in conjunction with the guide groove to ensure that the explosion-proof lamp body 120 automatically and without deviation slides into the unique predetermined position during the adsorption process.

[0053] Corresponding to the mounting base 110, the explosion-proof lamp body 120 can be designed as a completely sealed, independent module without any external electrical interfaces. Its back can be designed with a mating boss that precisely matches the shape and size of the V-shaped guide groove on the mounting base. This boss is not only crucial for mechanical positioning, but also integrates embedded functional components that work in conjunction with the various units of the mounting base. Inside the mating boss, corresponding to the position of the permanent magnet on the mounting base, a soft iron material with high magnetic permeability can be embedded. This design effectively concentrates magnetic lines of force, significantly enhances the magnetic attraction effect, and concentrates the attraction force more at the design center.

[0054] refer to Figure 2The installation methods for explosion-proof lighting fixtures include:

[0055] S210. When the explosion-proof lamp body is detected to be close to the mounting base, the control guide and adsorption unit adsorb and position the explosion-proof lamp body.

[0056] It should be noted that the detailed installation process begins with the operator roughly guiding the explosion-proof lamp body towards the mating surface of the mounting base. During this process, precise aiming is not required. Once the explosion-proof lamp body enters the effective magnetic field range established by the permanent magnet at the front of the mounting base, the powerful magnetic force actively captures the lamp body and pulls it to the surface of the mounting base. At this point, the mating boss on the back of the lamp body meets the V-shaped guide groove of the mounting base. Under the combined action of magnetic force and gravity, the lamp body automatically slides down the inclined surface of the guide groove and centers itself, ultimately being firmly adsorbed in a clear and repeatable posture. This process not only achieves rapid macroscopic positioning, but the continuous positive pressure provided by the permanent magnet adsorption force also lays the foundation for stable operation afterwards.

[0057] S220. Based on the magnetic induction intensity information obtained by the locking and sensing unit, determine the real-time installation position and attitude of the explosion-proof lamp body.

[0058] It should be noted that after the control guide and adsorption unit adsorbs and positions the explosion-proof lamp body, the system seamlessly enters the micro-positioning self-diagnosis stage. The instant the lamp body is physically in place is considered a trigger event, waking up the controller (MCU) inside the mounting base. The MCU immediately begins executing a preset diagnostic program, the core of which is to accurately quantify the real-time installation position and attitude of the explosion-proof lamp body.

[0059] S230. Detect whether the real-time installation position and posture meet the preset alignment conditions.

[0060] S240. When the real-time installation position posture is detected to meet the preset alignment conditions, the control locking and sensing unit performs rigid mechanical locking on the explosion-proof lamp body, and the energy and control unit supplies power to the explosion-proof lamp body.

[0061] The solution of this invention can improve the problems of cumbersome operation, high safety risk, low efficiency, unstable installation quality and poor long-term reliability caused by heavy reliance on manual labor in the existing explosion-proof lighting installation methods.

[0062] Optionally, based on the above embodiments, the locking and sensing unit 112 includes a preset number of Hall effect sensors; the Hall effect sensors are encapsulated in a guide groove and arranged in an array within the guide groove; the Hall effect sensors are electrically connected to the controller.

[0063] For example, a group of Hall effect sensors can be arrayed around key geometric locations surrounding the V-shaped guide groove. The layout of these Hall effect sensors can be optimized to most sensitively capture subtle changes in the spatial gradient of the permanent magnet's magnetic field on the explosion-proof lamp body, thus providing high-resolution raw data for subsequent micro-positioning diagnostics. The controller, integrated within the energy and control unit 113, processes the input signals from all Hall effect sensors and executes the core positioning algorithm and safety logic judgments.

[0064] Figure 3 This is a flowchart of another installation method for explosion-proof lighting fixtures provided in an embodiment of the present invention, see reference. Figure 3 The method includes the following steps:

[0065] S310. When the explosion-proof lamp body is detected to be close to the mounting base, the control guide and adsorption unit adsorb and position the explosion-proof lamp body.

[0066] S321. Obtain the real-time voltage signal value with magnetic induction intensity information output by each Hall effect sensor.

[0067] S322. Integrate the real-time voltage signal values ​​into a real-time position state vector.

[0068] S323. Determine the real-time installation position and attitude of the explosion-proof lamp body based on the position state vector.

[0069] Understandably, when an explosion-proof lamp body is attracted, its inherent permanent magnets will create a specific magnetic field distribution in the surrounding space. Hall effect sensors can accurately sense this magnetic field and output a set of real-time voltage signal values ​​related to the magnetic induction intensity at each position. These real-time voltage signal values ​​are integrated into a real-time, multi-dimensional position state vector, which can comprehensively and quantitatively characterize the precise position and orientation of the explosion-proof lamp body relative to the mounting base, including any possible minute translations, rotations, or fitting gaps.

[0070] In the above embodiment, step S220 may include steps S321-S323.

[0071] S331. Determine the position deviation based on the real-time position state vector and the pre-calibrated standard position state vector.

[0072] It should be noted that before checking whether the real-time installation position and attitude meet the preset alignment conditions, calibration can be performed in the factory or initialization environment using a standard luminaire confirmed to be in an absolutely ideal installation position. In this state, the MCU acquires a voltage reading from the Hall sensor and uses this data as the gold standard, storing it in non-volatile memory to form a standard position state vector. The installation quality is objectively evaluated by calculating the difference between the real-time position state vector and the stored standard position state vector.

[0073] S332. Based on the position deviation, determine whether the real-time installation position and attitude meet the preset alignment conditions.

[0074] It should be noted that the MCU determines whether the real-time installation position and orientation meet the preset alignment conditions based on the position deviation, thereby objectively evaluating the installation quality.

[0075] Optionally, based on the above embodiments, step S230 may include steps S331 and S332.

[0076] Understandably, the core principle of determining whether the real-time installation position and attitude meet the preset alignment conditions lies in mathematically comparing the real-time position state vector with the pre-calibrated standard position state vector. By calculating the difference between these two vectors, a quantified position deviation can be obtained. This data-driven comparison method eliminates the uncertainty of human judgment and achieves an objective and automated assessment of installation accuracy. The preset alignment conditions can be further specified as follows: the calculated position deviation must be less than or equal to a preset tolerance threshold. This setting provides a clear technical standard for installation accuracy.

[0077] Optionally, based on the above embodiments, the position deviation is calculated as follows: Where n is the total number of Hall effect sensors; The real-time voltage signal value acquired by the i-th Hall effect sensor; This is the i-th standard voltage signal value that constitutes the standard position state vector.

[0078] Understandably, this formula essentially calculates the Euclidean distance between two high-dimensional vectors in the vector space. Only when this distance... The system only considers the installation position to be accurate when it is less than or equal to the preset tolerance threshold.

[0079] Optionally, based on the above embodiments, the locking and sensing unit 112 includes an electromagnetic actuator and a mechanical locking pin; the mechanical locking pin is disposed inside the electromagnetic actuator; the electromagnetic actuator is electrically connected to the controller; a metal core is pre-embedded in the mating boss corresponding to the position of the mechanical locking pin; the energy and control unit also includes a primary induction coil, which is electrically connected to the controller; a secondary induction coil is embedded in the mating boss corresponding to the position of the primary induction coil. The primary induction coil can be flat and closely attached to the inner wall of the mating joint, used to generate an alternating magnetic field for wireless power transmission.

[0080] For example, the locking and sensing unit 112 is responsible for the final rigid fixation and precise position confirmation of the explosion-proof lamp body 120. When driven by the controller, the electromagnetic actuator can push a mechanical locking pin made of hard alloy to extend axially. On the central axis of the mating boss, corresponding to the position of the mechanical locking pin of the mounting base, a metal core, also made of hard alloy and possessing high shear strength, can be pre-embedded. This core is designed with grooves or through holes that match the head of the locking pin, ensuring a gapless and robust rigid connection when engaged. Furthermore, corresponding to the position of the primary induction coil, a secondary induction coil with optimized turns and shape is embedded inside the mating boss. This coil receives energy transmitted from the mounting base and converts it into stable DC power through a rectifier and filter circuit at the rear, powering the light source and its drive circuit inside the explosion-proof lamp body 120. Through this structural design, the explosion-proof lamp body 120 achieves complete physical and electrical isolation from the external environment, eliminating the need for any wiring operations during replacement.

[0081] S340. When the real-time installation position posture is detected to meet the preset alignment conditions, the electromagnetic actuator is activated, driving the mechanical locking pin to extend and physically engage with the metal core, supplying current to the primary induction coil, so that the primary induction coil and the secondary induction coil form a wireless power transmission system to power the explosion-proof lamp body.

[0082] Understandably, this invention activates an electromagnetic actuator within the mounting base via a controller, driving the mechanical locking pin to extend and physically engage with the pre-installed metal core on the back of the explosion-proof lamp body. This composite fixing structure of "permanent magnet adsorption + mechanical locking" is key to the high stability of this invention. Permanent magnet adsorption provides continuous pre-tightening force, effectively suppressing high-frequency micro-vibrations; while rigid mechanical locking provides strong shear resistance, capable of withstanding severe impacts and large vibrations, fundamentally preventing the lamp from sliding or falling off. The primary induction coil within the mounting base and the secondary induction coil within the explosion-proof lamp body constitute a wireless power transmission system. This method completely eliminates physical electrode contact, avoiding safety hazards such as poor contact and sparks caused by environmental humidity, corrosion, or vibration, greatly improving the long-term electrical reliability of the system in harsh environments.

[0083] In the above embodiment, step S240 may include step S340.

[0084] Optionally, based on the above embodiments, after step S230, the method further includes: when the real-time installation position posture is detected to meet the preset alignment conditions and an activation command is detected, the control locking and sensing unit performs rigid mechanical locking on the explosion-proof lamp body, and the energy and control unit supplies power to the explosion-proof lamp body.

[0085] Understandably, to further enhance operational safety and standardization, this invention introduces an authorized activation mechanism. The final execution of the rigid mechanical locking and energy coupling requires a dual condition check: not only must the installation position and orientation pass self-diagnostic verification, but the mounting base must also receive a specific activation command from an external specialized tool. This "correct position + authorized operation" logic ensures that the system only enters the working state when qualified personnel perform the intended operation and the installation quality meets the standards, thus preventing misoperation and substandard installation.

[0086] It should be noted that when the real-time installation position and attitude meet the preset alignment conditions, the system enters the judgment and execution phase of the safety interlocking logic. The MCU's decision logic is designed as a rigorous double-condition AND gate. The system not only requires that the position deviation be less than or equal to a preset, extremely small tolerance threshold to confirm the accuracy of the physical position, but it must also receive a valid activation command issued by an external special tool held by the operator. Only when both conditions are met simultaneously does the MCU determine the current state as "safe and authorized" and immediately execute subsequent actions. First, it outputs a drive pulse to the electromagnetic actuator, causing its internal mechanical locking pin to quickly extend and precisely engage with the metal core inside the explosion-proof lamp body, forming an irreversible rigid mechanical connection. After confirming that the locking mechanism is fully in place, the MCU then activates the primary induction coil in the energy and control unit to begin non-contact energy coupling, providing stable power to the explosion-proof lamp body and illuminating it.

[0087] Optionally, based on the above embodiments, after step S230, the method further includes: issuing a warning signal when it is detected that the real-time installation position attitude does not meet the preset alignment conditions.

[0088] It is understood that the embodiments of the present invention have intelligent error prevention and warning functions. When it is detected that the real-time installation position does not meet the preset alignment conditions, the system will automatically suppress the execution of all subsequent key steps such as locking and power supply, and can selectively issue warning signals through indicator lights or other means to intuitively inform the operator that there is a problem with the installation and that readjustment is required.

[0089] It should be noted that if the positional deviation exceeds the threshold, even if an activation command is received, the MCU will actively suppress all outputs and issue a clear "installation not in place" warning to the operator by flashing the LED indicator on the mounting base.

[0090] Optionally, based on the above embodiments, after step S240, the method further includes: when an unlocking command is detected, controlling the locking and sensing unit to release the rigid mechanical lock, cutting off the power supply, so that the explosion-proof lamp body returns to the state of separation by magnetic attraction only.

[0091] It should be noted that the replacement process for explosion-proof lighting fixtures is also designed to be extremely simple and safe. When a fixture needs to be replaced, maintenance personnel use a special tool to send an unlocking command to the mounting base. Upon receiving this command, the MCU executes a logic sequence that is the complete opposite of the installation process. First, it immediately cuts off the power supply to the primary induction coil, extinguishing the light fixture. Next, it cuts off the power supply to the electromagnetic actuator, causing its internal mechanical locking pin to automatically retract under the action of a return spring and other structures, thus releasing the rigid mechanical lock. After these operations are completed, only the permanent magnet attraction remains between the lamp body and the mounting base. At this point, the operator only needs to apply a pulling force slightly greater than this attraction to easily remove the old lamp body. The entire process requires no tools to directly contact the lamp or mounting base, and no live parts are exposed.

[0092] Understandably, this invention also provides a similarly simple and safe replacement process corresponding to the installation process. By issuing an unlocking command to the mounting base, the system can automatically and safely release the rigid mechanical lock and cut off the power, allowing the explosion-proof lamp body to return to a state of separation relying solely on magnetic attraction. Operators can easily remove it, achieving "tool-free and highly efficient" maintenance throughout the entire process.

[0093] In the embodiments of this invention, the advanced nature of its technical solution is mainly reflected in two deeply integrated core design concepts: a composite anchoring mechanics scheme and a Hall effect-based intelligent closed-loop control system. First, the composite anchoring mechanics scheme constructed in this invention is a significant innovation over traditional single-fixation methods. It does not simply superimpose two forces, but utilizes the complementary advantages of two forces with vastly different properties in different application scenarios to form a stable system. The permanent magnet adsorption force, as a continuously existing passive force, primarily contributes by providing a strong, perpendicular positive pressure to the contact surface. This positive pressure not only ensures a tight, gapless fit between the lamp body and the mounting base, which is crucial for ensuring wireless energy transmission efficiency and preventing moisture intrusion; more importantly, it generates significant static friction, effectively suppressing resonance or minute displacement caused by high-frequency, low-amplitude industrial environmental vibrations, ensuring the microscopic stability of the lamp during daily operation. However, when facing low-frequency, high-energy impacts caused by the start-up and shutdown of large equipment, accidental collisions, or earthquakes, relying solely on friction is insufficient to prevent macroscopic slippage of the lamp. At this point, the electromagnetic mechanical locking force plays a decisive role. When the electromagnetic actuator drives the mechanical locking pin to rigidly engage with the metal core inside the lamp body, it provides extremely high shear strength in the direction parallel to the contact surface. This physical "hard connection" directly resists and absorbs strong shear stress, fundamentally eliminating the possibility of lateral or rotational displacement of the lamp body. Therefore, the permanent magnet adsorption force is responsible for "static" and "microscopic" stability, while the electromagnetic mechanical locking force is responsible for "dynamic" and "macroscopic" safety. The two work together to form the mechanical basis for the high stability of this invention. Secondly, the deeper innovation of this invention lies in the construction of a complete intelligent closed-loop control system based on the Hall effect. This system transforms the open-loop process of traditional installation, which relies on human observation and manual operation, into a closed-loop feedback control process that can self-perceive, autonomously judge, and automatically execute, thereby transferring the decision-making power for installation quality from the operator to the system itself. The operating logic of this closed-loop system can be clearly described as a cycle containing three links: perception, decision-making, and execution. The system begins with the "sensing" stage, where a Hall effect sensor array precisely and in real-time captures the installation position and attitude information of the lamp, converting it into a digital position state vector. This is equivalent to equipping the system with "micrometer-level" eyes. Next comes the "decision-making" stage, handled by the microcontroller (MCU). Upon receiving the sensed data, the MCU doesn't immediately execute an action. Instead, it first performs a high-speed comparison with a stored ideal state benchmark, calculating the position deviation to quantitatively assess the current state. This step is the core of the system's intelligence; it determines whether the installation meets preset, stringent quality standards based on objective data rather than subjective judgment. Simultaneously, by monitoring external authorization signals, a comprehensive decision-making logic is formed that considers both the physical state and the operational intent.Finally, there's the "execution" phase. Based on the decision, the MCU issues explicit instructions to the electromagnetic actuators and energy transfer units—either to perform locking and power supply, or to maintain suppression and issue a warning. The result of the execution itself can be sensed by the system again, forming a deeper confirmation loop. The entire process, from perception to execution, constitutes a complete, rigorous, and non-manually-intervened feedback control loop, ensuring that every installation operation strictly adheres to optimal standards, fundamentally improving the system's reliability and safety.

[0094] In summary, this invention, by employing non-contact energy coupling technology, completely eliminates the exposure and contact of physical electrodes, fundamentally preventing the risk of poor contact and electrical sparks caused by environmental humidity, vibration, or corrosion. Simultaneously, the built-in self-diagnosis and authorized activation dual safety logic ensures that locking and power supply only occur when the luminaire is perfectly and precisely positioned, forming a robust electrical and mechanical double safety net, achieving true "fail-safe" design. By transforming the cumbersome and time-consuming cable wiring and multi-point bolt tightening process of traditional technology into a nearly intuitive "proximity-activation" action, operators no longer need to carry multiple tools or perform precise alignment. This reduces high-risk operations that might take tens of minutes to be completed within tens of seconds, saving valuable human resources and significantly reducing personnel exposure time in high-risk environments. This endows the luminaire with unprecedented dynamic environmental adaptability and long-term stability. The permanent magnet attraction provides a continuous and powerful pre-tightening force, effectively suppressing high-frequency micro-vibrations common in industrial environments and preventing loosening of connections; while the rigid mechanical locking provides strong shear resistance, sufficient to withstand the severe impacts from the start-up and shutdown of large equipment or accidental collisions. The organic combination of these two mechanical mechanisms ensures that the luminaire maintains long-term, reliable stability even under the most demanding dynamic conditions. By eliminating the dependence of installation quality on the operator's personal skills and experience, a high degree of standardization and reliability is achieved. Whether the installation is in place no longer depends on subjective human judgment, but rather on the system's objective determination through precise, quantifiable data acquisition and comparison using a Hall effect sensor array. This data-driven self-diagnostic process ensures that every installation accurately reproduces the ideal state, eliminating installation defects caused by human negligence or lack of experience, and giving the installation quality machine-level stability and consistency. This reduces the overall lifecycle maintenance costs and complexity of the equipment. The luminaire replacement process is simplified to a modular operation of "command unlock - easy removal - new placement," without requiring disconnection of the main power supply or any complex disassembly. This "plug-and-play" feature means that maintenance can be quickly completed by ordinary inspection personnel without waiting for professional electrical engineers, which greatly reduces equipment downtime and the need for highly skilled personnel, thus demonstrating significant economic benefits throughout the entire service life of the equipment.
