At the same time, due to the particularity of underwater environment, the sealing, corrosion resistance and stability of corner reflector are put forward with extremely high requirements.

[0003] The existing underwater corner reflector is mostly manufactured by integral casting or welding, which ensures the integrity of the structure to a certain extent, but the manufacturing cost is high, and once damaged, it is difficult to repair or replace. In addition, when the traditional corner reflector is used in combination, it often needs to be realized through complex connecting mechanism, which not only increases the installation difficulty, but also reduces the stability and reliability of the system.

[0004] In terms of sealing, traditional underwater corner reflector usually adopts mechanical sealing or O-ring sealing, but these sealing methods are easily affected by underwater pressure, temperature change and corrosion during long-term use, which leads to the decline of sealing performance, and further affects the acoustic performance and service life of the corner reflector.
