[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0016] Embodiment 1

[0017] Please refer to Figures 1-4 , the present utility model provides a sealing structure for the rotating component of a fire extinguishing device, including a fixed component 1. The outer wall of the fixed component 1 is rotatably assembled with a rotating component 2. The upper end of the rotating component 2 is connected to the main body 3 of the fire extinguishing device by screws. A seal ring structure 4 is filled and assembled between the rotating component 2 and the fixed component 1. A connecting groove 6 is opened on the side wall of the fixed component 1, and a second seal ring 5 is assembled on the inner walls of the two grooves 6. The second seal ring 5 is in close fit with both the rotating component 2 and the fixed component 1.

[0018] The fire extinguishing device is an automatic tracking and positioning jet fire extinguishing device. The rotating component 2 and the fixed component 1 are both prior arts, which ensure the rotation range and the fire extinguishing range of the automatic tracking and positioning jet fire extinguishing device. Through the setting of the groove 6, it is convenient to prevent the second sealing ring 5, with multiple sealing protections, ensuring the sealing effect between the rotating component 2 and the fixed component 1 and avoiding water leakage problems. At the same time, the setting of the sealing ring structure 4 makes the connection between the fixed component 1 and the rotating component 2 in a vacuum-sealed state. When under pressure, the sealing ring structure 4 has a deformation space and better fills between the fixed component 1 and the rotating component 2, solving the problem of water leakage when the moving component 2 rotates.

[0019] The sealing ring structure 4 includes a first sealing ring 41 and a slotted groove 42. The first sealing ring 41 is assembled between the fixed component 1 and the rotating component 2, and four slotted grooves 42 are evenly arranged on the surface of the first sealing ring 41.

[0020] The first sealing ring 41 is arranged between the fixed component 1 and the rotating component 2, and at the same time makes the connection between the fixed component 1 and the rotating component 2 in a vacuum-sealed state. By setting four slotted grooves 42, the main body of the first sealing ring 41 can have a deformation space when under pressure and better fills between the fixed component 1 and the rotating component 2, ensuring the sealing effect.

[0021] The second sealing ring 5 is set as a water-swellable water stop strip.

[0022] When the water-swellable water stop strip encounters the leaked water, it will immediately expand and better fill and seal between the fixed component 1 and the rotating component 2.
