Description

A waterproof and moisture-proof sealed cabin for underwater robots Technical Field

[0001] This utility model relates to the field of underwater robot technology, specifically a waterproof and moisture-proof sealed cabin for underwater robots. Background Technology

[0002] An underwater robot is an autonomous or remotely operated unmanned robot capable of performing tasks in underwater environments. Designed for scientific research, exploration, maintenance, and operation in oceans, lakes, and other bodies of water, it requires excellent underwater operational stability. To ensure that the robot's internal electronic equipment, batteries, and other critical components are protected from water corrosion and damage during underwater operation, a sealed enclosure is needed. Common sealed enclosures typically use ordinary sealing rings at the openings. This method of sealing is simplistic, and if the sealing rings are damaged, the underwater robot cannot be guaranteed to operate effectively in harsh underwater environments. Summary of the Invention

[0003] In order to overcome the above-mentioned defects in the existing technology, this utility model provides a waterproof and moisture-proof sealed cabin for underwater robots.

[0004] A waterproof and moisture-proof sealed chamber for an underwater robot includes a chamber body. The chamber body has a mounting base and a sealing cover at both ends. The mounting base has a connector plug. An inwardly extending annular protrusion is provided on the inner side of the mounting base. The annular protrusion is threadedly connected to the chamber body. A first sealing ring is provided at the connection between the annular protrusion and the chamber body. A lamp base is provided on the side of the chamber body near the sealing cover. A first connecting protrusion is provided at the end of the lamp base. Second connecting protrusions are provided on the outer wall of the end of the chamber body and on the outer wall of the opening of the sealing cover. The first connecting protrusion is located between the two second connecting protrusions. Sealing rings cover the outer sides of the two second connecting protrusions. A second sealing ring and a third sealing ring are provided at the connection between the chamber body and the lamp base, and at the connection between the sealing cover and the lamp base, respectively.

[0005] Furthermore, the sealing ring has a U-shaped cross-section, including connecting portions on both sides and a sealing portion in the middle. A fixing component is provided on the outer side of the sealing ring. The fixing component includes two fixing rings. The two fixing rings cooperate with the second connecting protrusion to clamp the connecting portion. The two fixing rings are fixedly connected by bolts.

[0006] Furthermore, the lamp base is provided with a first arc-shaped mounting plate on the side away from the first connecting protrusion, and a second arc-shaped mounting plate is provided on the side away from the mounting substrate of the annular protrusion. The first arc-shaped mounting plate and the second arc-shaped mounting plate correspond to each other, and the first arc-shaped mounting plate and the second arc-shaped mounting plate are provided with mounting grooves for mounting circuit boards.

[0007] Furthermore, the cabin has side wings on both sides, and propellers are mounted on the side wings.

[0008] Furthermore, the side of the cabin closest to the mounting base plate has a stepped structure, and a fourth sealing ring is provided at the stepped structure.

[0009] Due to the adoption of the above technical solutions, the beneficial technical effects of this utility model are as follows: In this utility model, mounting base plates and sealing covers are provided on both sides of the cabin body, which mainly solves the sealing connection relationship between the cabin body and the cover. The mounting base plate is threadedly connected to the cabin body through annular protrusions. A first sealing ring is provided at the connection between the annular protrusions and the cabin body. A lamp plate base is provided on the side of the cabin body near the sealing cover. The first connecting protrusion is clamped and fixed by the outer wall of the end of the cabin body and the second connecting protrusion on the outer wall of the opening of the sealing cover. The outer covers of the two second connecting protrusions are covered with sealing rings, which ensures the sealing performance of the connection between the sealing cover, the lamp plate base and the cabin body. Furthermore, a second sealing ring and a third sealing ring are provided at the connection between the cabin body and the lamp plate base, and at the connection between the sealing cover and the lamp plate base, respectively, which further improves the sealing performance of the cabin body.
