Underwater electronic compartment

Abstract

The invention relates to an underwater electronic cabin, which comprises a pressure-resistant casing and an electronic docking frame. The pressure-resistant shell is installed on the underwater carrier, and the electronic docking frame is installed inside the pressure-resistant shell. The pressure-resistant shell is that the connector end head and the top end head are positioned radially with the jacket respectively through the slit groove and the slit boss, and are connected together by the connecting ring, the first connecting flange and the second connecting flange. Structure; the debugging of electronic components and testing instruments on the electronic docking frame is realized through the additional debugging adapter frame assembly. The sealing of the pressure-resistant shell of the present invention is realized by the O-shaped sealing ring between the shell and the head through the pre-tightening of the set screw so that the O-shaped sealing ring produces a certain amount of deformation, and the sealing performance is reliable; the socket connection of the present invention The device is a movable structure, which makes the docking of the electronic docking frame easy to realize; the electronic docking frame of the present invention has the functions of radial positioning, axial positioning, and radial buffering; the present invention debugs the docking of the adapter frame and the docking plate assembly, System remote debugging can be realized.

Description

technical field [0001] The present invention relates to underwater operations, in particular to a device which is suitable for underwater use and has sufficient strength and reliable sealing performance, and is used to install electronic components and detection instruments so that they will not be corroded by seawater pressure and seawater. And the failure or damage of the underwater electronic cabin. Background technique [0002] The electronic cabin for underwater robot operation has a pressure-resistant shell and its internal electronic frame. In the prior art, the underwater dry-type pressure-resistant shell can be roughly divided into a spherical shell and a cylindrical shell according to the shape. Among them, the spherical shell has the best weight-displacement ratio, but the disadvantage is that the fluid movement resistance is large, and it is not convenient for the arrangement of internal electronic components and testing instruments. The cylindrical shell has lo...

Problems solved by technology

Among them, the spherical shell has the best weight-displacement ratio, but the disadvantage is that the fluid movement resistance is large, and it is not convenient for the arrangement of internal electronic components and testing instruments.

The cylindrical shell has low resistance to fluid movement, the highest utilization rate of internal space and is the easiest to process and manufacture. The disadvantage is that the weight-displacement ratio is high

Among them, the fixed electronic rack has a low space utilization rate inside the pressure-resistant shell, and is inconvenient for the installation, debugging and maintenance of internal electronic components and testing instruments.

The movable electronic rack has a relatively high space utilization rate inside the pressure-resistant shell, and the electronic rack can be pulled out of the pressure-resistant shell as a whole, which is more convenient for the installation, debugging and maintenance of internal electronic components and testing instruments. The difference is that it is inconvenient to connect the plug and socket connectors inside the pressure-resistant housing, and the electronic rack must be pulled out of the pressure-resistant housing for operation. Each group of connectors must correspond to each other one by one, and the tail wires of the socket connectors must be compared. Long, the operation is cumbersome, and the socket connector tail wire and solder joints are easily damaged during the operation
