Description

Technical Field

[0001] This utility model relates to an explosion-proof lamp, and more particularly to a dual-cavity explosion-proof heat dissipation lamp structure. Background Technology

[0002] Explosion-proof lighting fixtures are used in hazardous locations where flammable gases and dust are present. They prevent potential arcs, sparks, and high temperatures generated inside the lamp from igniting flammable gases and dust in the surrounding environment, thus meeting explosion-proof requirements. Due to their application characteristics, explosion-proof lighting fixtures are commonly used in special fields such as public security, fire protection, military, power, railway, petroleum, and chemical industries. Depending on the application scenario, explosion-proof lighting fixtures are mainly classified into flameproof explosion-proof lighting fixtures, safety explosion-proof lighting fixtures, and mobile explosion-proof lighting fixtures. Explosion-proof platform lights are suitable for lighting in flammable and explosive locations such as petrochemical plants, oil platforms, gas stations, oil pump rooms, and transfer stations, as well as in Zone 1 and Zone 2 explosive gas environments and Zone 21 and Zone 22 flammable dust environments.

[0003] For applications like mines and flour mills, where the working environment is complex and demands high levels of sealing performance (dustproof, waterproof, etc.) from explosion-proof lights, existing lights rely on traditional sealing ring technology for internal sealing. This typically involves manually installing the sealing ring in the designated position before assembly, making it highly susceptible to human error and variations in the quality of the sealing ring itself. This results in inconsistent product quality, failure to meet sealing requirements, and a low yield rate. Furthermore, single-cavity explosion-proof lights do not separate the lighting and power supply structures, leading to poor protection in the event of internal combustion or explosion. In flour mills, where sealing and stability are paramount, inadequate sealing can easily cause accidents. Additionally, most explosion-proof lights rely solely on solid heat dissipation structures, resulting in limited cooling effectiveness and a generally low overall safety factor. Utility Model Content

The annular locking member is disposed on the protective shell to lock the bottom edge structure of the annular sealing structure. The clamping component is disposed on the annular sealing structure and moves towards the annular locking member to push the annular sealing structure against the protective shell for a tight seal.

[0007] Preferably, the annular sealing structure is a double-layer structure, including a coupling layer on the outer side and a clamping layer on the inner side.

[0013] Preferably, the dual-cavity explosion-proof heat dissipation lamp structure further includes a heat dissipation component, which includes a liquid heat dissipation structure and a solid heat dissipation structure. The liquid heat dissipation structure is spirally arranged outside the light source cavity and surrounds the combined cavity, and can transfer the heat generated by the light source circuit board and the battery to the outside of the protective housing through the solid heat dissipation structure.

The protective housing 401 has a coupling groove that matches the size of the combined cavity 1 and the light source cavity 2. The coupling groove and the protective housing 401 are integrally formed or fixed by a detachable connection. The detachable connection is a snap-fit ​​or threaded connection. One side of the protective housing 401 can be opened. The openable part of the structure is sealed with a gasket. The openable structure facilitates the maintenance and replacement of the structure inside the protective housing 401.

[0041] The sealing component 402 is used to cover and seal the structure at the installation opening. The edge structure of the installation opening has threads on both sides. The annular sealing structure 403 is a double-layer structure, including a first coupling part on the outer side and a second coupling part on the inner side. The shapes of the two sets of coupling parts are adapted to the shape of the installation opening. The tops of the two sets of coupling parts are connected, and the bottoms are open. The distance between the two sets of coupling parts forms a clamping space for clamping the installation opening. The structures on both sides of the installation opening are provided with threads.

[0045] Example 2

[0046] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 11 As shown below, see details:

[0047] In a preferred embodiment, the annular sealing structure 403 is a double-layer structure, including an outer coupling layer 406 and an inner abutting layer 407. The coupling layer 406 is connected to the top structure of the abutting layer 407, and the space formed by the distance between them is used to clamp the structure at the opening of the protective shell 401. The top of the abutting layer 407 is provided with a blind groove 408 to connect with the abutting assembly 405. Furthermore, the double-layer annular sealing structure 403 is used to cover and seal the structure at the opening of the protective shell 401. The coupling layer 406 and the abutment layer 407 are both annular. The size of the annular space formed by the distance between the two is adapted to the size of the structure at the opening of the protective shell 401. The annular space is in a sealed state. The coupling layer 406 and the abutment layer 407 are integrally formed structures. The blind groove 408 is a circular groove. The depth of the groove is adapted to the height of the abutment layer 407. The shape of the blind groove 408 is adapted to the shape of the abutment component 405. The edge structure of the blind groove 408 is provided with limiting clamps. There are multiple sets of limiting clamps used to limit the position of the abutment component 405.

[0048] In a preferred embodiment, the clamping assembly 405 includes a clamping member 409, a turning rod 410, and an airbag sealing structure 411. The clamping member 409 is disposed in the blind groove 408 and has a threaded structure 412 inside. The turning rod 410 is turned to be threadedly connected to the threaded structure 412, thereby causing the clamping member 409 to press against the inner wall of the blind groove 408. Furthermore, the turning rod 410 is a threaded rod that can be threadedly connected to the threaded structure 412. The top of the turning rod 410 is provided with a convenient turning element, which includes a fixing block connected to the turning rod 410. The fixing block is surrounded by a lever, which allows personnel or tools to turn the lever. The rotation of the lever causes the tightening lever 410 to move and screw into the threaded structure 412. A fixing member is provided on the inner wall of the blind groove 408. The fixing member can restrict the position of the clamping member 409 and prevent the clamping member 409 from separating from the blind groove 408. The structure of the clamping member 409 at the threaded structure 412 has a certain deformation capability. When the tightening lever 410 is coupled with the threaded structure 412, it will apply a force from the center outward to the clamping member 409, thereby causing the clamping member 409 to apply a force in the same direction to the blind groove 408 to achieve the clamping effect. When the clamping member 409 moves downward to the bottom of the blind groove 408, it will squeeze the airbag sealing structure 411. The airbag sealing structure 411 is used for further sealing.

[0049] In a preferred embodiment, the airbag sealing structure 411 includes a compressed air chamber 413 and a deformation sealing ring 414. The compressed air chamber 413 is located at the bottom of the blind groove 408 and communicates with the deformation sealing ring 414. The deformation sealing ring 414 is located between the blind groove 408 and the abutment layer 407. During the threaded connection between the screw rod 410 and the threaded structure 412, the compressed air chamber 413 is compressed, forcing gas into the deformation sealing ring 414, thereby abutting the protective shell 401 against the abutment layer 407. The abutment member 409 is generally annular and consists of two sets of arc-shaped structures 415. The arc-shaped structure 415 has its two ends spaced a certain distance apart. Furthermore, the compressed air chamber 413 is filled with gas, and the edge structure of the compressed air chamber 413 is connected to the deformation sealing ring 414. The gas-filled structure of the deformation sealing ring 414 deforms. When the screwing rod 410 is screwed down, it gradually connects with the threaded structure 412. The bottom structure of the screwing rod 410 will contact the compressed air chamber 413. When the screwing rod 410 descends to a certain distance, it will squeeze the compressed air chamber 413, thereby forcing the gas into the deformation sealing ring 414. The deformation sealing ring 414 deforms, thereby sealing the mating layer 407 and the protective shell 401 tightly, resulting in a stronger sealing effect. Two sets of arc-shaped structures 415 are arranged opposite each other to share the same center, forming a circular structure. The arc-shaped structures 415 have a certain height to increase the contact area with the blind groove 408. The two sets of arc-shaped structures 415 are arranged at a certain distance. When the screw rod 410 moves downward by screwing, it will apply a force to the outside of the blind groove 408 to the arc-shaped structures 415, thereby pressing the arc-shaped structures 415 and the blind groove 408 together.

[0050] In a preferred embodiment, the coupling layer 406 and the abutment layer 407 are provided with threaded grooves 416 on the side corresponding to the protective housing 401 for threaded connection with the protective housing 401. The bottom of the coupling layer 406 is provided with a sealing element 417 and a shallow groove 418. The sealing element 417 is used to seal the protective housing 401, and the shallow groove 418 is used to house the annular locking element 404. Furthermore, the structures on both sides of the opening of the protective housing 401 are provided with threaded sections that can be threadedly connected to the threaded grooves 416 on the inner side of the coupling layer 406 and the inner side of the abutment layer 407. The coupling layer 406 and the abutment layer 407 are provided to clamp and seal the structures on both sides of the opening of the protective shell 401. The sealing element 417 and the coupling layer 406 are integrally formed structures. The sealing element 417 includes an extension and a sealing part connected thereto. A shallow groove 418 is provided in the extension. The size of the shallow groove 418 is adapted to the size of the annular locking element 404 for clamping. The edge structure of the shallow groove 418 is provided with a detachable limiting block. The limiting block is used to limit the annular locking element 404 to prevent the two from separating. The sealing part can seal the structure at the connection gap between the coupling layer 406 and the protective shell 401.

[0051] In a preferred embodiment, the protective housing 401 has a slot 419 corresponding to the position of the seal 417. The slot 419 surrounds the protective housing 401, and the annular locking member 404 tightens to couple the seal 417 with the slot 419. Further, the slot 419 is an annular groove surrounding the protective housing 401, positioned near the opening of the protective housing 401. The slot 419 is upwardly inclined and conical in shape. The shape of the seal 417 matches the shape of the slot 419. The inner wall of the slot 419 has multiple small conical grooves, and the seal 417 has protrusions that match the small conical grooves. When the seal 417 couples with the slot 419, the protrusions couple with the small conical grooves. The annular locking member 404 tightens to seal the slot 419 and the seal 417, resulting in a good sealing effect.

[0052] In a preferred embodiment, the annular locking member 404 includes an arc-shaped clamping member 420 and an adjusting structure 421. Two sets of arc-shaped clamping members 420 are provided, and the adjusting structure 421 is located between the two sets of arc-shaped clamping members 420. The adjusting structure 421 adjusts the distance between the two sets of arc-shaped clamping members 420 by extending and retracting to tighten the coupling layer 406 and the protective shell 401. Furthermore, the two sets of arc-shaped clamping members 420 can be combined to facilitate the tightening and sealing of the coupling layer 406 and the protective shell 401. After the two sets of arc-shaped clamping members 420 are combined... The structure is annular to clamp and seal both parts. The two sets of arc-shaped clamping parts 420 have connecting parts at both ends to be detachably connected to the adjustment structure 421. The detachable connection is a snap-fit ​​or threaded connection. The adjustment structure 421 includes a fixed part and telescopic parts connected to both sides. The telescopic parts adjust the length of the overall structure by telescopic movement, thereby adjusting the distance between the two sets of arc-shaped clamping parts 420. The telescopic parts are equipped with locking rods at corresponding positions to lock the structure after telescopic movement. The overall structure is more stable and has a better locking and sealing effect on the coupling layer 406 and the protective shell 401.

[0053] In a preferred embodiment, the liquid heat dissipation structure 501 includes a heat pipe 503 and a heat dissipation liquid 504. The heat dissipation liquid 504 is assembled inside the heat pipe 503. The heat pipe 503 is spirally arranged in the light source cavity 2. A clamping groove 505 is provided at the center of the heat pipe 503 for clamping the combined cavity 1. Furthermore, the heat pipe 503 is an integrally formed structure, with adjacent spiral annular tubes in close contact to improve the heat conduction effect. The structure of the heat pipe 503 in contact with the light source cavity 2 is a planar structure to increase the contact area and further improve the heat conduction and heat dissipation effect. The heat pipe 503 located at the center is provided with an L-shaped piece for clamping the combined cavity 1. Multiple sets of L-shaped pieces are provided to increase the contact area with the combined cavity 1, thereby improving the heat conduction effect. Multiple sets of L-shaped pieces form a clamping groove for clamping the combined cavity 1.

[0054] In a preferred embodiment, the solid heat dissipation structure 502 includes a plurality of transfer pipes 506 and heat sinks 507. The transfer pipes 506 are arranged radially at a certain distance to connect the structure at the bend of the heat conduction pipe 503. The transfer pipes 506 are connected to the heat sinks 507. Furthermore, multiple sets of transfer pipes 506 are arranged at a specific distance. The transfer pipes 506 are arranged circumferentially with the center position of the heat conduction pipe 503 as the center. The structure at the bend of the heat conduction pipe 503 is provided with multiple sets of connecting ports. Each set of transfer pipes 506 can connect the connecting port located at the center position of the heat conduction pipe 503 with the connecting port located on the outer side of the circumference, so that the overall structure is distributed in a mesh shape, further improving the heat dissipation and heat conduction effect. The transfer pipes 506 can transfer the received heat to the outside of the protective shell 401 through the heat sinks 507 for heat dissipation.

[0055] In a preferred embodiment, the heat sinks 507 are spaced apart outside the protective housing 401. The protective housing 401 contains L-shaped fixing pieces 422 for supporting the heat dissipation assembly 5.

Furthermore, the heat sinks 507 are fin-shaped and located on the outside of the protective housing 401. They are made of aluminum and serve as part of the protective housing 401, thus enhancing its height. To improve heat dissipation, multiple sets of L-shaped fixing plates 422 are used to fix the heat dissipation component 5. The L-shaped fixing plates 422 and the protective housing 401 are fixed by threaded connection or snap-fit. One side of the L-shaped fixing plate 422 is used to clamp the heat dissipation component 5, and the other side is used to support it. The transparent tempered glass 423 allows the lamp bead 301 in the light source cavity 2 to emit light and illuminate the outside. The protective housing 401 is provided with a sealing groove for the transparent tempered glass 423 to be placed and fixed. The overall structure has good sealing performance.
