Description

A marine solar explosion-proof lamp Technical Field

[0001] The invention belongs to the technical field of explosion-proof lamps, and in particular relates to a marine solar explosion-proof lamp. Background Art

[0002] With the rapid development of industries like petroleum, chemical, and mining, lighting fixtures are increasingly used in production, warehousing, and rescue operations, with a growing variety of products. Preventing accidental explosions from lighting fixtures in explosive gas-hazardous areas has become a crucial issue. Since lighting fixtures inevitably generate sparks or hot surfaces during operation, encountering explosive gas mixtures at production or rescue sites can lead to explosions, directly endangering the lives of citizens and national property. Therefore, as the most widely used lighting fixture, its explosion-proof technology has long garnered widespread attention and significant attention. These fixtures feature an aluminum alloy housing with a plastic-sprayed surface; dual-purpose lighting and emergency functions; a maintenance-free nickel-cadmium battery pack that automatically charges under normal power supply and automatically activates in the event of a power outage or blackout; steel conduit wiring; separate normal and emergency lighting functions within emergency lamps; and dual-purpose lighting and emergency lamps, which share a single body with independent light sources. These explosion-proof lamps are also increasingly being used on ships.

[0003] Today's explosion-proof lamps have higher wear and tear during later maintenance and are only slightly better than ordinary lamps in terms of pressure resistance.

They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] As shown in Figure 1-10, a marine solar explosion-proof lamp includes an explosion-proof protective shell 1, characterized in that a connecting device 3 is provided inside the explosion-proof protective shell 1, and the disassembled lamp body 2 slides inside the explosion-proof protective shell 1. A through groove 4 and a limiting annular groove 5 are provided on the disassembled lamp body 2. The disassembled lamp body 2 slides on the connecting device 3 through the through groove 4, and the disassembled lamp body 2 drives the disassembled lamp body 2 to move inside the explosion-proof protective shell 1 through the limiting annular groove 5.

[0031] The explosion-proof protective shell 1 is installed and fixed by pulling the connecting device 3 out of the explosion-proof protective shell 1. When the connecting device 3 is pulled out, the connecting device 3 allows the disassembled lamp body 2 to slide out of the explosion-proof protective shell 1. The disassembled lamp body 2 is quickly connected by the connecting device 3 through the groove 4 and the limiting annular groove 5. The disassembled lamp body 2 can quickly change the wearing parts.

[0032] As shown in FIG1-10 , the explosion-proof protective shell 1 includes a shell 1-1 and a sliding storage cavity 1-2. The shell 1-1 is provided with a sliding storage cavity 1-2 for storing a disassembled lamp body 2, and a connecting device 3 is provided inside the shell 1-1.

[0033] The housing 1 - 1 protects the detachable lamp body 2 disposed inside the sliding storage cavity 1 - 2 .

[0034] As shown in Figure 1-10, the disassembled lamp body 2 includes a movable lamp body 2-1, a replaceable lamp holder 2-2, an explosion-proof lampshade 2-3, a sealing device 2-4 and a clamping device 2-5. The movable lamp body 2-1 is provided with a replaceable lamp holder 2-2, a sealing device 2-4 and a clamping device 2-5. The clamping device 2-5 makes the explosion-proof lampshade 2-3 and the sealing device 2-4 fit tightly.

[0035] The explosion-proof lampshade 2-3 and the replaceable lamp holder 2-2 are wearing parts and can be replaced. The sealing device 2-4 and the clamping device 2-5 can be used to ensure the sealing of the explosion-proof lampshade 2-3 when the lamp body 2 is disassembled.

[0036] As shown in Figure 1-10, the explosion-proof lampshade 2-3 includes a glass lampshade 2-3-1, a mounting claw 2-3-2 and a limit bar 2-3-3. The glass lampshade 2-3-1 is provided with a mounting claw 2-3-2 for fixing, the limit bar 2-3-3 limits the rotation angle of the glass lampshade 2-3-1, and the clamping device 2-5 squeezes the glass lampshade 2-3-1 to fit the sealing device 2-4.

[0037] The glass lampshade 2-3-1 is installed and fixed by the installation claws 2-3-2, and the limit strip 2-3-3 limits the rotation angle of the glass lampshade 2-3-1.

[0038] As shown in Figure 1-10, the sealing device 2-4 includes a first sliding cavity 2-4-1, a first spring 2-4-2, a limiting ring 2-4-3 and a sealing sleeve 2-4-4. The first sliding cavity 2-4-1 is arranged inside the shell 1-1, the first spring 2-4-2 is arranged inside the first sliding cavity 2-4-1, the sealing sleeve 2-4-4 slides inside the first sliding cavity 2-4-1 through the limiting ring 2-4-3, the first spring 2-4-2 is arranged between the first sliding cavity 2-4-1 and the sealing sleeve 2-4-4, and the sealing sleeve 2-4-4 is fitted with the glass lampshade 2-3-1.

[0039] The first spring 2-4-2 applies pressure to the glass lampshade 2-3-1 through the sealing sleeve 2-4-4 to ensure the sealing.

[0040] As shown in Figure 1-10, the clamping device 2-5 includes a second sliding groove 2-5-1, a sliding plate 2-5-2, a second spring 2-5-3, a connecting column 2-5-4, a clamping arc plate 2-5-5 and an extrusion slope 2-5-6. The second sliding groove 2-5-1 is arranged inside the shell 1-1, the sliding plate 2-5-2 slides inside the second sliding groove 2-5-1, the second spring 2-5-3 is arranged between the sliding plate 2-5-2 and the second sliding groove 2-5-1, the connecting column 2-5-4 is arranged on the sliding plate 2-5-2, the clamping arc plate 2-5-5 is arranged on the connecting column 2-5-4, and the clamping arc plate 2-5-5 is provided with an extrusion slope 2-5-6 for pushing the mounting claw 2-3-2.

[0041] The rotation of the glass lampshade 2-3-1 drives the mounting claw 2-3-2 to rotate and squeeze the clamping arc plate 2-5-5. However, due to the extrusion slope 2-5-6 on the clamping arc plate 2-5-5, the clamping arc plate 2-5-5 moves to the top of the glass lampshade 2-3-1, and then the compressed second spring 2-5-3 pushes the glass lampshade 2-3-1 and the sealing sleeve 2-4-4 to fit together through the clamping arc plate 2-5-5.

[0042] As shown in Figure 1-10, the connecting device 3 includes a sliding limit groove 3-1, a sliding plate 3-2, a third spring 3-3, a first rack 3-4, a fixed gear 3-5, a movable groove plate 3-6, a tooth surface 3-7 and a pushing column 3-8. The sliding limit groove 3-1 is arranged inside the shell 1-1, the sliding plate 3-2 slides inside the sliding limit groove 3-1, a third spring 3-3 is provided between the sliding limit groove 3-1 and the sliding plate 3-2, the first rack 3-4 is arranged on the sliding plate 3-2, the fixed gear 3-5 is arranged inside the shell 1-1 and meshes with the first rack 3-4, the movable groove plate 3-6 slides inside the shell 1-1, the movable groove plate 3-6 is provided with a tooth surface 3-7 meshing with the fixed gear 3-5, the movable groove plate 3-6 is provided with a pushing column 3-8, and the pushing column 3-8 enters the limiting annular groove 5 through the groove 4.

[0043] During installation, the first rack 3-4 is pulled out from the inside of the shell 1-1, and the moving first rack 3-4 pushes the moving groove plate 3-6 outward through the fixed gear 3-5. The moving groove plate 3-6 pushes the disassembled lamp body 2 outward through the push column 3-8. When an unexpected situation occurs and the explosion-proof protective shell 1 is detached from the installation, the compressed third spring 3-3 will reset the first rack 3-4 and retract it into the inside of the shell 1-1. The moving first rack 3-4 moves the moving groove plate 3-6 through the fixed gear 3-5, and the moving groove plate 3-6 drives the disassembled lamp body 2 to retract into the inside of the shell 1-1 for protection.

[0044] As shown in FIG1-10 , the pushing column 3-8 is arranged on the movable groove plate 3-6 toward the center of the movable lamp body 2-1.

[0045] This makes the movable lamp body 2-1 receive a more uniform force when being pushed by the pushing column 3-8.
