Description

Technical Field

[0001] This utility model relates to the field of navigation lighting equipment technology, and in particular to an aviation obstruction light. Background Technology

[0002] Aviation obstruction lights are specialized lighting fixtures installed on buildings, communication towers, chimneys, wind power generation equipment, and facilities around airports to mark the location and height of obstacles, ensuring the safety of aircraft flying at low altitudes. These lights typically feature high brightness, good weather resistance, and a long service life, generally alerting pilots to potential obstacles through flashing or constant light signals. Aviation obstruction lights operate in high-altitude, inclement weather, or complex environments; therefore, they require high quality and safety performance.

[0003] While existing aviation obstruction lights possess basic explosion-proof capabilities, their explosion-proof performance levels still fall short of the requirements for many specific high-risk scenarios, such as facilities installed in environments with flammable and explosive gases or dust. Current explosion-proof devices typically employ simple sealing and isolation methods, but these have limitations in preventing explosions caused by high temperatures, high pressures, or electrical sparks. This inadequate explosion-proof performance not only restricts the application scenarios of aviation obstruction lights but also poses potential safety hazards in practical applications.

[0004] Therefore, there is an urgent need for an aviation obstruction light with high explosion-proof performance, which can further enhance its safety protection against the external environment through structural optimization, so as to ensure the stable and reliable operation of the aviation obstruction light and eliminate potential safety hazards. Utility Model Content

[0005] In view of at least one of the above technical problems, the present invention provides an aviation obstruction light that improves explosion-proof performance by adopting structural improvements.

[0006] According to a first aspect of the present invention, an aviation obstruction light is provided, comprising: The shell body has an opening at one end and an internal storage space; An explosion-proof wiring cavity is formed on the housing body and communicates with the accommodating space. The explosion-proof wiring cavity also has a wire-passing hole, an explosion-proof clamping nut is installed on the wire-passing hole, and a wiring cover is installed on the explosion-proof wiring cavity. A mesh cover, connected to the opening, has a glass bubble inside that is fixedly connected to the housing; A light-emitting element is disposed inside the glass bulb and is fixedly connected to the inside of the housing body; The glass bulb is sealed to the housing, and the wiring cover is sealed to the explosion-proof wiring cavity.

[0007] In some embodiments of this utility model, the housing body includes an explosion-proof housing and an explosion-proof pressure ring, the opening is formed on the explosion-proof pressure ring, the connection between the explosion-proof housing and the explosion-proof pressure ring has a stop structure, and a locking member is provided outside the connection.

[0008] In some embodiments of this utility model, multiple support columns are fixedly connected inside the explosion-proof housing, and a platform plate is provided at the other end of the support column. There is a gap between the platform plate and the housing body, and the light-emitting element is fixedly installed on the platform plate.

[0009] In some embodiments of this utility model, the explosion-proof housing sidewall is further provided with an explosion-proof expansion cavity, the explosion-proof expansion cavity is connected to the accommodating space, an explosion-proof cover is threaded onto the explosion-proof expansion cavity, and the accommodating space is further provided with an mounting plate disposed opposite to the position of the explosion-proof expansion cavity, the mounting plate is fixedly connected to the platform plate and has a gap with the interior of the housing body.

[0010] In some embodiments of this utility model, the connection between the housing and the mesh cover has a fixing post protruding from the housing, and the mesh cover has a fixing hole recessed opposite to the fixing post, and the fixing hole is connected to the fixing post by a screw.

[0011] In some embodiments of this utility model, the glass bulb has a first extending edge that extends horizontally outward, the opening has a second extending edge that extends horizontally inward, the glass bulb is sleeved in the opening, and the first extending edge and the second extending edge are fixedly connected.

[0012] In some embodiments of this utility model, the first extension edge and the second extension edge are sealed and bonded together with adhesive.

[0013] In some embodiments of this utility model, the bottom of the housing also has a fixed corner bracket.

[0014] In some embodiments of this utility model, a fall arresting chain is connected to the wiring cover, and the other end of the fall arresting chain is connected to the mesh cover.

[0015] In some embodiments of this utility model, a sealing ring is also provided at the connection between the explosion-proof wiring cavity and the wiring cover.

[0016] The beneficial effects of this utility model are as follows: By designing a wire-passing hole in the explosion-proof wiring cavity and installing an explosion-proof clamping nut in the wire-passing hole, the wiring harness can pass through the explosion-proof clamping nut to connect the interior of the housing space with the exterior of the aviation obstruction light, and achieve a sealed connection, effectively avoiding explosion hazards at the wiring harness.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] like Figures 1 to 8 The aviation obstruction lights shown include: The shell body 1 has an opening 11 at one end and an internal receiving space 12; such as Figure 1 , Figure 5 As shown, the interior of the accommodating space 12 is used to accommodate wires and light-emitting elements 5 or other external structures that can be installed inside.

[0024] An explosion-proof wiring cavity 2 is located on the housing body 1 and communicates with the receiving space 12. The explosion-proof wiring cavity 2 also has a wire-passing hole 21, on which an explosion-proof clamping nut 22 is installed. A wiring cover 23 is installed on the explosion-proof wiring cavity 2. During installation, the wiring harness used to provide power passes through the receiving space 12 into the explosion-proof wiring cavity 2, then through the explosion-proof clamping nut 22 to the outside. The explosion-proof clamping nut 22 and the wiring harness are sealed together. If wiring harness maintenance is required, the wiring cover 23 can be removed for maintenance. The wiring cover 23 is also sealed to the explosion-proof wiring cavity 2. It should be noted that one, two, or more wire-passing holes 21 and explosion-proof clamping nuts 22 can be provided. It should also be noted that a sealing ring 9, a sealing strip, or other sealing structure can be provided between the explosion-proof wiring cavity 2 and the wiring cover 23.

[0025] The mesh cover 3 is connected to the opening 11 and has a glass bubble 4 that is fixedly connected to the shell inside; The light-emitting element 5 is disposed inside the glass bulb 4 and is fixedly connected to the inside of the housing body 1; The glass bulb 4 is sealed to the housing, and the wiring cover 23 is sealed to the explosion-proof wiring cavity 2. It should be noted that the sealing connection between the glass bulb 4 and the housing can take many forms, including adhesive, a sealing element at the connection point, or other sealing structures.

[0026] This invention features a wire-passing hole 21 designed on the explosion-proof wiring cavity 2, with an explosion-proof clamping nut 22 installed inside. This allows the wiring harness to pass through the explosion-proof clamping nut 22, connecting the interior of the housing 12 to the exterior of the aviation obstruction light, achieving a sealed connection and effectively avoiding explosion hazards at the wiring harness. The sealed connection between the glass bulb 4 and the housing further enhances the overall airtightness of the lamp, ensuring that the internal environment of the light-emitting element 5 is not disturbed by external gases, while also preventing the impact on the outside in the event of an internal explosion. The sealed design of the wiring cover 23 and the explosion-proof wiring cavity 2 protects the internal electrical components and wires, eliminating the possibility of electrical leakage or external contamination in traditional structures. The mesh cover 3 protects the glass bulb 4. This structure effectively prevents external mechanical impacts from damaging the seal and light-emitting element 5 of the aviation obstruction light, significantly improving the safety and durability of the aviation obstruction light. It solves the problem of insufficient sealing level of traditional aviation obstruction lights in complex and high-risk scenarios, giving the aviation obstruction light higher explosion-proof performance.

[0027] like Figure 2 , Figure 5 , Figure 6 and Figure 8As shown, to facilitate the replacement and maintenance of the light-emitting element 5 inside the housing, the housing body 1 includes an explosion-proof housing 13 and an explosion-proof pressure ring 14. An opening 11 is formed on the explosion-proof pressure ring 14. The connection between the explosion-proof housing 13 and the explosion-proof pressure ring 14 has a stop 13a structure, and a locking member 13b is provided outside the connection. By separating the housing and providing a stop 13a structure at the connection between the explosion-proof housing 13 and the explosion-proof pressure ring 14, a seal can be achieved through the stop 13a and the locking member 13b. The separate design of the explosion-proof housing 13 and the explosion-proof pressure ring 14 makes the replacement of the light-emitting element 5 and the maintenance of internal components more convenient. When maintenance is required, only the locking member 13b needs to be opened to remove the explosion-proof pressure ring 14 to directly access the light-emitting element 5, without completely removing the entire lamp or damaging the fixed state of the explosion-proof housing 13. This significantly reduces the complexity and risk of high-altitude operations while improving maintenance efficiency.

[0028] The light-emitting element 5 is installed inside the housing. To make the installation of the light-emitting element 5 more secure, such as... Figure 5 , Figure 7 As shown, multiple support columns 62 are fixedly connected inside the explosion-proof housing 13. A platform plate 6 is provided at the other end of each support column 62. There is a gap between the platform plate 6 and the housing body 1. The light-emitting element 5 is fixedly installed on the platform plate 6. The gap between the platform plate 6 and the housing body 1 prevents them from contacting each other, facilitating the passage of each component's wiring harness. The platform plate 6 is supported by the support columns 62, and the light-emitting element 5 is installed on it. It should be noted that the platform plate 6 and the support columns 62 are interchangeable to accommodate different light-emitting elements 5. The platform surface is at the same height as the stop 13a, making replacement and maintenance easier; the explosion-proof pressure ring 14 can be opened for replacement and maintenance. It should also be noted that the height of the platform plate 6 can be the same as the stop 13a or at a similar height above or below the stop. Setting the height close to the stop height allows for better operation by staff during maintenance.

[0029] In aviation obstruction lights, in addition to the light-emitting element 5, other structures can be added to cooperate with the light-emitting element 5. In some embodiments of this invention, such as... Figure 5As shown, the explosion-proof housing 13 also has an explosion-proof expansion cavity 7 on its side wall, which communicates with the receiving space 12. An explosion-proof cover 71 is threaded onto the explosion-proof expansion cavity 7. The receiving space 12 also has a mounting plate 61 positioned opposite to the explosion-proof expansion cavity 7. The mounting plate 61 is fixedly connected to the platform plate 6 and has a gap with the interior of the housing body 1. The gap allows the wire harness to pass through. It should be noted that the size of the gap can be adjusted according to the thickness and position of the wire harness during actual use. Similarly, the mounting plate 61 and the platform plate 6 can be an integrally formed structure. Specifically, the integral forming can be achieved by first setting the positions for mounting the light-emitting element 5 and connecting the support column 62 on the platform plate 6, and then bending the other positions at 90° to form the mounting plate 61. In practical use, other electronic components can be added internally. These components are mounted on the mounting plate 61 and pass through the explosion-proof expansion cavity 7 to contact the outside. If explosion-proof sealing of the internal electronic components is required, it can be achieved by rotating the explosion-proof cover 71 through its threads, thereby improving the overall explosion-proof performance of the structure. In some embodiments of this invention, to achieve a higher explosion-proof performance level, the explosion-proof cover 71 is mounted on the explosion-proof expansion cavity 7 via a threaded connection.

[0030] like Figure 4 As shown, in some embodiments of this utility model, the connection between the housing and the mesh cover 3 has a protruding fixing post 15, and the mesh cover 3 has a recessed fixing hole 31 opposite to the fixing post 15. The fixing hole 31 is connected to the fixing post 15 by a screw 32. The fixing post 15 and the fixing hole 31 allow for more precise positioning during installation. By aligning the fixing hole 31 with the fixing post 15, the screw 32 can be passed through and tightened. The recessed fixing hole 31 on the mesh cover 3 can be precisely aligned with the fixing post 15, and the connection by the screw 32 increases the tightness and firmness of the connection, thereby improving the overall sealing performance and resistance to external pressure of the mesh cover 3 and the housing.

[0031] like Figure 8As shown, in some embodiments of this utility model, the glass bulb 4 has a first extending edge 41 extending horizontally outward, and the opening 11 has a second extending edge 11a extending horizontally inward. The glass bulb 4 is fitted inside the opening 11, and the first extending edge 41 and the second extending edge 11a are fixedly connected. During production, the glass bulb 4 is passed through the opening 11, so that the glass bulb 4 is fitted inside the opening 11. The second extending edge 11a is used to hold the first extending edge 41 in place, and then the glass bulb 4 is fixedly connected to the housing. This not only significantly improves the connection strength between the glass bulb 4 and the opening 11, but also optimizes the overall sealing performance of the aviation obstruction light. The fixed connection of the horizontal extending edges forms a surface contact support structure, making the force distribution more uniform and greatly improving the pressure resistance and impact resistance of the connection area. The combination of double-layer edges increases the sealing performance of the lamp, reduces the possibility of external gas, dust, or liquid entering the lamp, and also ensures that if internal components explode, it will not affect the external environment, thus enabling the lamp to operate safely for a long time.

[0032] In some embodiments of this utility model, the first extension edge 41 and the second extension edge 11a are sealed and bonded together with adhesive. By adding adhesive, the connection achieves the dual functions of mechanical fixation and chemical sealing, effectively compensating for the structural gap problem in traditional connection methods, enhancing the bonding strength between the extension edges, and forming a complete sealing barrier at the joint to prevent external liquids, gases, or particles from entering the lamp, preventing internal explosions from affecting the external environment, improving the airtightness of the aviation obstruction light, and giving the connection long-term protective capabilities, effectively ensuring the stable use of the lamp in extreme weather conditions.

[0033] like Figure 2 , Figure 7 As shown, in some embodiments of this utility model, the bottom of the housing also has a fixing bracket 16. The fixing bracket 16 structure provides additional mechanical support for the aviation obstruction light by reinforcing the connection between the bottom of the housing and the mounting surface, improving the stability of the light fixture, providing more contact points for installation, dispersing the mechanical pressure generated during installation, and adapting to the shape of different mounting surfaces, such as horizontal, vertical, or inclined surfaces, through its angle design. Specifically, the bracket can be connected by bolts or welding to achieve a high-strength connection, further reducing the risk of displacement of the light fixture due to vibration or wind load, and providing a more reliable installation guarantee for long-term operation.

[0034] Aviation obstruction lights typically involve multiple detachable components, such as wiring covers 23 and mesh covers 3. These components are frequently disassembled and maintained during long-term use, posing a risk of accidental detachment or loss. Especially in installation environments at high altitudes or far from the ground, if a component falls, not only will the inability to retrieve it increase maintenance costs, but it may also pose a safety threat to personnel or equipment below. Figure 2 As shown, a fall arresting chain 8 is connected to the wiring cover 23, with the other end of the chain 8 connected to the mesh cover 3. The fall arresting chain 8, through its secure connection, forms a physical protection mechanism, ensuring that the wiring cover 23 remains physically connected to the lighting fixture even after disassembly or loosening, thus preventing accidental detachment. This ensures that the wiring cover 23 is firmly fixed to the lighting fixture, preventing parts from falling even during harsh high-altitude operations or other complex environments.

[0035] The explosion-proof wiring cavity 2 of an aviation obstruction light is typically a critical area for electrical connections. It houses the wiring and electrical components required for the light's operation, and the connection point is a vital component of the light's protective performance. This is especially true in complex external environments, such as those with strong winds, rain, dust, corrosive gases, or vibration. If the connection between the wiring cover 23 and the explosion-proof wiring cavity 2 is not reliably sealed, leaks can easily occur, allowing external substances to enter the cavity and potentially cause short circuits, equipment damage, or even explosions. Figure 3 As shown, a sealing ring 9 is also provided at the connection between the explosion-proof wiring cavity 2 and the wiring cover 23. The sealing ring 9 can form a flexible and airtight protective barrier between the two connecting parts. With the help of the elasticity and resilience of the sealing ring 9, the connection can maintain good airtightness and waterproof performance under normal use environment, and can effectively adapt to the sealing challenges caused by high temperature, vibration or slight deformation of parts.
