Description

Technical Field

[0001] The present invention belongs to the technical field of explosion-proof lamps, and in particular relates to a new pure explosion-proof lamp and an application method thereof. Background Art

[0002] As society's safety requirements for public spaces continue to increase, fire emergency lighting and evacuation indicators have become widely used as key equipment to ensure the evacuation and escape of personnel. Especially in emergencies such as fires and power outages, these lamps can provide guidance and illumination to ensure safe evacuation. Therefore, they are widely installed in commercial buildings, industrial sites, and public facilities.

[0003] While fire emergency lighting and evacuation indicator lights differ in function, their basic structures share a certain degree of commonality. Both require explosion-proof designs, typically feature metal housings, and contain light source modules. However, differences in size, optical design, display mode, and specific usage scenarios make it difficult to achieve a single, multi-purpose design with traditional structural designs.

DETAILED DESCRIPTION

[0061] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0062] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0063] like Figures 1 to 13 As shown, a new type of pure explosion-proof lamp includes:

[0064] The explosion-proof main body 1 is obtained by processing metal profiles. The metal profiles include a ring body 11 that surrounds an explosion-proof cavity 13. The design of the ring body 11 can provide a compact and stable explosion-proof cavity structure to ensure the safety of the lamp in dangerous environments, as well as two convex edges 12 protruding outward relative to the ring body 11. The ring body 11 and the convex edges 12 are integrally formed by a mold; the lighting strip 2 is installed on the outside of the ring body 11 and is located between the two convex edges 12, and is connected to the wiring harness led out from the explosion-proof cavity 13; the transparent glass plate 3 is partially inserted between the two convex edges 12, covering the lighting strip 2 and emitting light through the illumination of the lighting strip 2, thereby ensuring the lighting function; the fixing structure 4 fixes the transparent glass plate 3 relative to the convex edges 12; the blocking structure 5 is provided in two pieces, which respectively block the two ends of the explosion-proof cavity 13, and the main structure of the pure explosion-proof new lamp is obtained by cooperating with the metal profiles.

[0065] In this embodiment, a new type of pure explosion-proof lamp is provided, which can be used as a fire emergency lighting lamp and an evacuation indicator light. The explosion-proof main body 1 is obtained by profile processing, realizing a new manufacturing method. Compared with the traditional die-casting structure, the profile processing is convenient, the size is highly controllable, and the structure is stable. The explosion-proof main body 1 shell serves as a fire emergency lighting lamp and an evacuation indicator light at the same time, realizing multiple uses of one mold and effectively reducing production costs.

[0066] The pure flameproof new lamp in this embodiment has a high flameproof rating and is less restricted by the use environment. Because the design is based on a glass material display, the display range will be larger and can be used in different directions.

[0067] The metal profile has a specific cross-sectional shape and size. Specifically in this embodiment, by controlling the processing mold of the metal profile, the ring body 11 that forms the explosion-proof cavity 13 and the integrated specific size processing of the two convex edges 12 can be achieved. The higher integrity can effectively ensure the explosion-proof performance; of course, in order to ensure the assembly requirements of the overall structure, the metal profile needs to be further processed, including but not limited to: drilling holes in the ring body 11 to achieve the penetration of the wiring harness through the hole position 14; processing the end of the ring body 11 to obtain an installation structure corresponding to the blocking structure 5.

[0068] In order to better achieve the installation stability of the transparent glass plate 3, as a preferred embodiment of the above, see Figures 2 to 5 , the fixed structure 4 includes:

[0069] Two limiting sliders 41 are provided, which are fixedly connected to the convex edges 12 respectively, and are limited to the transparent glass plate 3 on both sides of the profile length direction, thereby preventing the transparent glass plate 3 from moving in this direction; the fixed frame 42 covers the edges of the transparent glass plate 3 outside the two convex edges 12, thereby effectively protecting the transparent glass plate 3. In order to better realize the positioning of the transparent glass plate 3 relative to the fixed frame 42, a recessed position for accommodating a local edge of the transparent glass plate 3 can be provided on the fixed frame 42, and the recessed position here can be a continuous groove structure; the fixed frame 42 is fixedly connected to the limiting slider 41.

[0070] The fixed connection between the limiting slider 41 and the flange 12, and the fixed connection between the fixing frame 42 and the limiting slider 41, effectively protects and secures the transparent glass plate 3 by surrounding it on all sides without damaging it, allowing the transparent glass plate 3 to remain stable during use. Specifically, during installation, the limiting slider 41 and the flange 12 can be fixedly connected using a connector 43. Similarly, the fixing frame 42 and the limiting slider 41 can be connected using the connector 43. To secure the connector 43, a through hole can be opened in the flange 12. This operation does not affect the explosion-proof performance of the lamp.

[0071] As a preferred embodiment of the above, Figure 6 and 7 As shown, the metal profile is outside the ring body 11 and located between the two convex edges 12, and is integrally formed along the length direction with:

[0072] The groove 15 provides a space for installing the lighting strip 2; two limiting surfaces 16 are symmetrically arranged on both sides of the groove 15, and the limiting surfaces 16 are restrained against the end faces of the transparent glass plate 3; the transparent glass plate 3 closes the open end of the groove 15.

[0073] In this way, the lighting strip 2 obtains a stable installation space, avoids the influence of the external environment, and ensures its service life; the groove 15 and the limiting surface 16 in this preferred embodiment can be formed in an integrated manner during the metal profile forming process without adding additional costs.

[0074] In order to further improve the installation stability of the transparent glass plate 3, as a preferred embodiment of the above, see also Figure 7The metal profile is outside the ring body 11 and located between the two convex edges 12. It is also integrally formed along the length direction with: two step structures 17 symmetrically arranged on both sides of the groove 15, and the step structures 17 connect the convex edge 12 and the limiting surface 16 on the same side; the transparent glass plate 3 is arranged between the two step structures 17, spaced apart from the convex edge 12, and the gap between them is filled with glue.

[0075] By filling with glue, the transparent glass plate 3 is fixed more stably, and a certain buffering effect can be achieved on both sides of the transparent glass plate 3, thereby reducing the interaction force between the transparent glass plate 3 and the explosion-proof body 1 in the event of vibration or collision, thereby ensuring the safe use of the transparent glass plate 3.

[0076] In the case of filling with glue, as preferred, see Figure 2 The new flameproof lamp also includes an annular light barrier 6, which is sleeved around the outer periphery of the transparent glass plate 3 and clamped between the limiting slider 41 and the fixing frame 42. This shields the gap between the transparent glass plate 3 and the ridge 12. The provision of the light barrier 6 not only ensures aesthetics after the glue is filled, but also blocks the illumination light from escaping the glue-setting structure, concentrating it on the transparent glass plate 3.

[0077] As a preferred embodiment of the above, see Figure 2 The blocking structure 5 includes a flameproof side cover 51 and a wire nut 52; the flameproof side cover 51 is connected to the flameproof main body 1 by threads and is provided with a through hole; the wire nut 52 is connected to the through hole of the flameproof side cover 51 by threads for the wiring harness to pass through.

[0078] In this preferred embodiment, the flameproof side cover 51 and the flameproof main body 1 together form a structural combination for achieving the flameproof function. The use of the wire nut 52 ensures convenient installation of the wiring harness and ensures the sealing of the wiring harness penetration point. During use, the wire nut 52 can be selected and matched accordingly with the wiring harness to ensure adaptive fit at the penetration point.

[0079] In order to improve the installation convenience of pure flameproof new lamps, see Figure 8 The metal profile also includes a guide belt 18 protruding outward relative to the ring body 11, and the guide belt 18, the ring body 11 and the protruding edge 12 are integrally formed by a mold; the pure flameproof new lamp also includes at least one mounting slider 8, which is arranged to slide linearly along the guide belt 18, and a fixed position for installing the connecting member 43 is opened on the mounting slider 8.

[0080] During the installation of a purely flameproof new lamp, the mounting slider 8 can be first secured. At this point, the mounting slider 8 is separated from the flameproof main body 1, making installation easier. The connectors 43 referred to herein include, but are not limited to, bolts, screws, and other structures. When more than one mounting slider 8 is provided, it is necessary to ensure that each mounting slider 8 is installed in the same straight line. After the mounting slider 8 is secured, the flameproof main body 1 can be mounted relative to the mounting slider 8 by sliding. This installation requires only docking the guide belt 18 and the mounting slider 8 and performing a linear sliding motion.

[0081] In this preferred embodiment, as a specific implementation method, see also Figure 8 The guide belt 18 can adopt a T-shaped cross-section, and a concave guide groove is formed between the two ends of one side of the T and the outer surface of the ring body 11, and two guide edges inserted into the guide groove are correspondingly provided on the mounting slider 8. The other parts of the mounting slider 8 except the guide edges can be appropriately spaced apart from the ring body 11 to avoid interference between the connecting member 43 and the ring body 11.

[0082] In order to ensure lighting in emergency situations, as a preferred embodiment of the above, Figure 14 and 15 As shown, the pure explosion-proof new lamp also includes at least one emergency lamp head module; the emergency lamp head module includes an emergency light 91 and a cable lead-in device 92, the emergency light 91 is directly or indirectly connected to the explosion-proof main body 1, and the cable lead-in device 92 is fixedly connected to the explosion-proof main body 1; the cable lead-in device 92 is led out from the explosion-proof cavity 13, and the wiring harness connected to the emergency light 91 is passed through and fixed.

[0083] In this preferred embodiment, the emergency light 91 can be installed by fixing it through the installation slider 8 in the above embodiment. This method is an indirect installation method relative to the explosion-proof main body 1. This method will reduce the impact on the explosion-proof main body 1. After the connection relationship between the emergency light 91 and the installation slider 8 is established, the connection relationship between the installation slider 8 and the explosion-proof main body 1 can be established; as another installation method of the emergency light 91, a threaded hole 19 can also be directly opened on the explosion-proof main body 1, and the connection relationship between the emergency light 91 and the explosion-proof main body 1 can be established through a connecting piece; the above two methods are both within the protection scope of the present invention.

[0084] As for the cable entry device 92, since the wiring harness needs to be led out from the explosion-proof cavity 13, it can be installed directly based on the hole for leading the wiring harness out. Specifically, the hole can be directly opened as a threaded hole 19, and a threaded rod structure is provided on the cable entry device 92, thereby realizing the rapid installation of the cable entry device 92 relative to the explosion-proof main body 1.

[0085] In order to ensure the intuitive evaluability of the status of the pure flameproof new lamp and improve the use effect of the product, as a preferred embodiment of the above, Figures 9 to 13 As shown, the pure flameproof new lamp also includes a test module 7 and a battery, wherein the battery can be arranged in the explosion-proof cavity 13, or can be protected by an additional structure outside the ring body 11;

[0086] The test module 7 includes a test light strip 71 with a plurality of lamp beads. The test light strip 71 is installed between the two convex edges 12 and is connected to the wiring harness led out from the explosion-proof cavity 13. In the longitudinal direction of the profile, the test light strip 71 and the lighting light strip 2 are arranged in parallel with each other. Figure 10 , showing the installation position of the test light strip 71, see Figure 11 , showing the specific form of parallel setting.

[0087] The fixed structure 4 covers the test light strip 71 and has light-transmitting holes corresponding to each lamp bead for light emitted by each lamp bead to pass through; taking the specific structural form of the fixed structure 4 including the limit slider 41 and the fixed frame 42 in the above embodiment as an example, Figure 12 and 13 As shown, an edge structure 42a covering the test light strip 71 can be formed by extending the end of the fixed frame 42, and the edge structure 42a can also be connected to the limit slider 41. This method can reduce the number of structural components; the test module 7 also includes a control unit, which is installed in the explosion-proof cavity 13. The control end 72 of the control unit passes through the ring body 11 and protrudes from the surface of the ring body 11; the control unit is respectively connected to the lighting light strip 2, the test light strip 71, the battery and the main power supply, and performs test control of the pure explosion-proof new lamp according to the user's operation on the control end 72.

[0088] In this preferred embodiment, the control unit can execute the test process under the control of the control terminal 72 through a pre-set program. This integrated test design makes the maintenance and repair of the lamp more efficient and reduces the complexity of manual operation. Specifically, the control unit can be based on a microcontroller and can be programmed to achieve multifunctional control, such as switching between lighting modes and test modes. To distinguish different test results, different lamp beads can be assigned different numbers, or lamp beads of different distinguishable colors can be used. The control terminal 72 in this preferred embodiment can specifically refer to a push-button or sliding switch structure.

[0089] In the normal use of the pure flameproof new lamp, after the main power supply is turned on, the lighting strip 2 can be controlled to light normally, and the normal lighting of at least one lamp bead on the test strip 71 can be tested. Within the set time period, the test is whether the illuminated lamp bead is extinguished, and whether the battery completes the set charging requirement after extinguishing, so as to judge the performance of the battery. In this test, the main power supply is AC22V power supply, and the test strip 71 includes red, green and yellow lamp beads, and the red lamp bead is used as the above-mentioned luminous lamp bead. The set time period is 24h, and the charging requirement is that the charging current is less than 20m Taking A as an example, after the main power supply is turned on, the red light bead must go out and the battery charging current must be less than 20mA within 24 hours to test the battery. A switching test between the main power supply and battery power supply can also be performed. For example, the main power supply is 1 minute, the emergency power supply is 20 seconds, the main power supply is 1 minute... and the switching is cyclical. Specifically, 50 times can be used as an example to test the switching between the main power supply and the battery. It is also possible to switch completely to battery power supply to determine whether the set discharge time can be met. Taking a 600mA battery as an example, the discharge time must exceed 2 hours.

[0090] In addition to the above tests, as a preferred method, the test control of the pure flameproof new lamp is performed according to the user's operation on the control terminal 72, including at least one of the following methods:

[0091] The first method is to turn on the main power supply, and if the control terminal 72 is continuously operated for less than the first time, the control unit controls the main power supply to be cut off, and the test light strip 71 switches from at least partially illuminating to completely extinguishing, entering an emergency state powered by the battery, and releasing the operation of the control terminal 72, returning to the main power supply state. In the implementation process, the first time can be specifically set to 3 seconds. Of course, other times are also sufficient, but the test efficiency needs to be comprehensively considered.

[0092] The second method is to turn on the main power supply, and the continuous operation time of the control terminal 72 is greater than or equal to the first time and less than the second time. The control unit controls one of the lamp beads of the test lamp strip 71 to flash at a first set frequency and enter an emergency state powered by the battery. The emergency state is automatically released after the set time and returns to the main power supply state; the flashing time can be specifically set to between 30 and 40 seconds, and the first set frequency can be 1Hz. Of course, the above values are only a specific example and are not intended to limit the protection range; based on the specific method of setting the first time to 3s, the second time can be 5s in this test; for the flashing lamp beads, lamp beads with specific numbers or specific colors can be specifically selected. In this embodiment, green can be specifically used as an example. This test process can be used as a monthly inspection test for pure flameproof new lamps;

[0093] The third method: The main power supply is turned on. If the control terminal 72 is continuously operated for a period greater than or equal to the second time and less than the third time, the control unit controls one of the lamps in the test light strip 71 to flash at a second set frequency and enter a battery-powered emergency state. This emergency state is exited upon the next operation of the control terminal 72, returning to the main power supply state. In this test, the same lamp as in the second method can be used for flashing, or a different lamp can be substituted. The third time can be set to 7 seconds, corresponding to the 3s and 5s in the above tests. Of course, this time only needs to increase in the order of the first, second, and third times, and the specific value can be selected as needed. To distinguish the test process, the flashing frequency needs to be set differently. In this test, by appropriately delaying the next operation of the control terminal 72, this test can be used to test whether the battery discharge time meets the required usage. For example, if the pure flameproof new type lamp is powered off before the next operation of the control terminal 72 is 30 minutes after the next operation, it indicates that the battery discharge time is insufficient. This process can be used as an annual inspection test for pure flameproof new type lamps.

[0094] In addition to the above tests, the control terminal 72 and the test light strip 71 can also realize the following functions. For example, in an emergency state, if the operation time of the control terminal 72 is greater than or equal to the third time, the emergency state output is turned off; or, in the main power supply state, if the battery is open or short-circuited, the set lamp beads in the test light strip 71 can be set to flash to alarm; or, in the main power supply state, in the above-mentioned monthly inspection test or annual inspection test, when the light source is open or short-circuited, the set lamp beads in the test light strip 71 can be set to flash to alarm.

[0095] As an application method of a new pure explosion-proof lamp, it can be specifically used as a fire emergency lighting lamp or an evacuation indicator light.
