[0002] Lamps are important applications on ships. They are not only used for lighting, but also as signals and for transmitting signals to other fishing boats. Some lights are also used to trap aquatic products. For this reason, the lights need to be varied to adapt to different working conditions. The lamps inside the cabin are always kept on. As the lamps are used for a longer time, the air pressure inside the lamps continues to increase. When the pressure rises to a certain level, if the pressure is not released, there is a risk of explosion. Summary of the invention

It is characterized in that a driving device 3 is arranged on the mounting shell 1, and the driving device 3 drives a transmission device 4 arranged on the mounting shell 1 to rotate, a rotating lampshade 5 is arranged on the transmission device 4, and the rotating lampshade 5 is sleeved on the fixed lampshade 2. After the rotating lampshade 5 rotates, it is connected with the fixed lampshade 2 so that the mounting shell 1 is depressurized outwardly, and a gas replenishing device 6 is arranged on the mounting shell 1 to replenish gas inside the mounting shell 1.

[0026] The driving device 3 monitors the pressure inside the installation shell 1. When the pressure increases to a certain level, the driving device 3 will drive the transmission device 4 to rotate. The rotating transmission device 4 drives the rotating lampshade 5 to rotate. The rotating lampshade 5 and the fixed lampshade 2 after rotation cooperate to make the installation shell 1 connected to the outside to release pressure outward.

[0029] When the air pressure rises to a certain level and the pressure applied to the moving column 3-5 is greater than the force of the first spring 3-6 and the limiting ball 3-7 acting on the first limiting hole 3-3 at the lower end, the moving column 3-5 will be pushed to move and the reset spring 3-4 will be compressed. At the same time, the moving column 3-5 moves to the limiting ball 3-7 and enters the first limiting hole 3-3 at the upper end, and then the pressure is relieved. When the pressure drops to a certain level and the elastic force compressing the first spring 3-6 is greater than the force of the limiting ball 3-7 acting on the first limiting hole 3-3 at the upper end, the moving column 3-5 is reset.

[0030] Among them, Figure 1-7As shown, the transmission device 4 includes a fixed rod 4-1, a rotating gear 4-2, a rotating gear ring 4-3 and a connecting hole 4-4, the fixed rod 4-1 is arranged on the mounting shell 1, the rotating gear 4-2 is arranged on the fixed rod 4-1, the rotating gear ring 4-3 rotates on the mounting shell 1, the connecting hole 4-4 is arranged on the rotating gear ring 4-3, the push rack 3-9 is connected with the rotating gear ring 4-3 through the rotating gear 4-2, and the rotating lamp cover 5 is arranged on the rotating gear ring 4-3 through the connecting hole 4-4.
