Description

Technical Field

[0001] This utility model relates to the field of thermal chamber lamp technology, and in particular to a thermal chamber lamp for nuclear environments. Background Technology

[0002] Hot chamber lamps are lighting devices specifically designed for highly radioactive environments (such as hot chambers in nuclear facilities). Their design must meet stringent requirements for radiation resistance, explosion protection, and protection against electric shock. Traditional hot chamber lamps typically mount the light source directly inside the hot chamber, which not only increases the risk of electric shock, fire, and explosion, but also exposes maintenance personnel to high levels of radiation.

[0003] Currently, the lampshades of hot chamber lamps are often made of polycarbonate (PC). PC has excellent impact resistance, high temperature resistance, and flame retardant properties, while also having good light transmittance. It is commonly used in hot chamber lampshades that require high safety and radiation resistance. However, long-term exposure to high radiation environments may lead to light decay and aging, thus requiring timely replacement of the lampshade. Since the hot chamber environment is not suitable for people to stay in for extended periods, lampshade replacement needs to be completed and installed more quickly to reduce the time people spend in the hot chamber.

[0004] Therefore, a nuclear environment hot chamber lamp is proposed to solve or alleviate the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a nuclear environment hot chamber lamp.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A nuclear environment hot chamber lamp includes a base, a lamp housing fixedly connected to the base, and a lamp shade. The lamp housing has two shade grooves and a connecting groove between the two shade grooves on the side away from the base. A lamp body is fixedly connected to the lamp housing located in the shade groove. Limiting blocks are fixedly connected to the two side walls of the connecting groove and spaced apart from their bottom surfaces. A guide slope is provided on the top surface of the limiting block. A connecting part that can be embedded in the connecting groove and abut against the bottom surface of the limiting block is fixedly connected between the two lamp shades.

[0008] Preferably, the lamp housing has grooves located on both sides of the two cover grooves, and the outer ring of the lamp cover is fixedly connected to an upwardly curved part. There is a gap between the curved part and the bottom of the groove. A limiting component is provided in the groove, and the limiting component can be moved above the curved part.

[0030] A nuclear environment hot chamber lamp, such as Figures 1 to 5 As shown, the lamp includes a base 2, a lamp housing 1 fixedly connected to the base 2, and a lamp shade 9. The lamp housing 1 has two shade grooves 6 and a connecting groove 7 between the two shade grooves 6 on the side away from the base 2. The base 2 is made of copper. A lamp body is fixedly connected to the lamp housing 1 located in the shade groove 6. Limiting blocks 17 are fixedly connected to the two side walls of the connecting groove 7 and spaced apart from its bottom surface. A guide slope 18 is provided on the top surface of the limiting block 17. A connecting part 10 that can be embedded in the connecting groove 7 and abut against the bottom surface of the limiting block 17 is fixedly connected between the two lamp shades 9.

[0031] The lamp housing 1 has grooves 8 located on both sides of the two cover grooves 6. The outer ring of the lamp cover 9 is fixedly connected to an upwardly curved part. There is a gap between the curved part and the bottom of the groove 8. A limiting component is provided in the groove 8. The limiting component can be moved to the top of the curved part. The curved part includes a thick curved part 11 integrally formed with the outer ring of the lamp cover 9 and a thin curved part 12 integrally formed with the thick curved part 11. The top surfaces of the thick curved part 11 and the thin curved part 12 are flush. The thickness of the thick curved part 11 is greater than the thickness of the thin curved part 12.

[0032] The limiting assembly includes a first rotating shaft 13 fixedly connected to the bottom surface of the groove 8, a first pressure plate 14 rotatably connected to the outer ring of the first rotating shaft 13, a second rotating shaft 15 fixedly connected to the bottom surface of the groove 8, and a second pressure plate 16 rotatably connected to the outer ring of the second rotating shaft 15. The first pressure plate 14 can be deflected above the upturned part, and the second pressure plate 16 can be deflected above the upturned part.

[0033] It also includes a connecting frame 3, which is U-shaped, and the lamp housing 1 is rotatably connected in the connecting frame 3. The lamp housing 1 and the connecting frame 3 can be positioned. The connecting frame 3 has grooves 4 on both sides that communicate with the outside. The lamp housing 1 is threaded with fixing bolts 5 located in the grooves 4 at both ends. The screw head of the fixing bolt 5 and the side wall of the lamp housing 1 clamp the connecting frame 3.

[0034] When the illumination angle needs to be adjusted, the operator only needs to manually rotate the fixing bolt 5 so that the screw head of the fixing bolt 5 and the lamp housing 1 no longer clamp the connecting frame 3. Then, the screw of the fixing bolt 5 can act as a pivot, so that the lamp housing 1 can change the angle relative to the connecting frame 3. After the angle is adjusted, the operator can manually tighten the fixing bolt 5 so that the screw head of the fixing bolt 5 can clamp the connecting frame 3 together with the lamp housing 1, so that the illumination angle will not change.

[0035] When the lamp body generates heat during operation, the heat can be transferred to the lamp housing 1, and the heat on the lamp housing 1 can then be transferred to the base 2. Since the base 2 is made of copper, the heat is more easily conducted away, preventing the lamp body from accumulating heat and being damaged.

[0036] When the lamp cover 9 is used in the nuclear environment for a long time, it will be damaged. When the operator needs to replace the lamp cover 9 as soon as possible, the operator only needs to manually rotate the first pressure plate 14 and the second pressure plate 16 so that the limiting component no longer blocks the flipped part. At this time, the operator can pinch the thin flipped part 12 and pull the lamp cover 9 directly so that the lamp cover 9 leaves the cover groove 6. At the same time, the connecting part 10 can contact the limiting block 17 and deform, so that the connecting part 10 can also leave the communicating groove 7.

[0037] Then, the operator aligns the new lampshade 9 and the connecting part 10 with the cover groove 6 and the connecting groove 7. The bottom of the connecting part 10 then contacts the guide slope 18 of the limiting block 17. Under the guidance of the guide slope 18, the connecting part 10 can fall into the connecting groove 7, so that the limiting block 17 can restrict the connecting part 10, thereby achieving the pre-positioning of the lampshade 9 and the connecting part 10. Then, by manually pressing down the flipped part and rotating the first pressing plate 14 and the second pressing plate 16, the limiting component can restrict the flipped part. In this way, the entire lampshade 9 can be further restricted, and the lampshade 9 can be replaced more quickly.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
