Description

TECHNICAL FIELD

[0001] The present application relates to the field of sealed boxes, in particular to a sealed cabin. BACKGROUND

[0002] The water surface acoustic communicator is a device designed specifically for communication between the water surface and underwater, which uses the propagation characteristics of sound waves in water to achieve long-distance transmission of voice and data. Unlike traditional radio communication, the water surface acoustic communicator transmits signals between water surface devices and underwater devices through sound waves, overcoming the problem of serious attenuation of electromagnetic waves in underwater transmission. Its working principle is to convert electrical signals into sound waves, propagate in water, and then convert sound wave signals back into electrical signals through receiving devices, thus completing communication. The water surface acoustic communicator is widely used in real-time communication between water surface and underwater operations, especially in submarines, divers, underwater unmanned devices, ocean research and military fields. It plays a crucial role in communication between the water surface and underwater, especially when traditional communication means cannot be used.

[0052] In order to solve the technical problem of poor sealing in the prior art, the application provides a sealed cabin.

[0053] Figures 1 to 7 A sealed cabin provided by the embodiment of the application includes a cabin body 1, a mounting plate 2 and a sealing stud 3. The cabin body 1 has a containing cavity 11. The cavity wall of the containing cavity 11 is provided with a first groove 12. The mounting plate 2 is arranged in the containing cavity 11. The mounting plate 2 is provided with a connecting hole 201 corresponding to the first groove 12. The sealing stud 3 includes a stud head 31 and a stud rod 32. The stud head 31 is inserted into the first groove 12. The side wall of the stud head 31 is provided with an annular groove 311. The annular groove 311 is provided with a first sealing ring 312. The first sealing ring 312 is tightly abutted with the groove wall of the first groove 12. The stud rod 32 is connected with the stud head 31 and penetrates through the connecting hole 201.
