Problems solved by technology

Chinese patent CN101804856 A discloses a compensation membrane type oil-filled junction box for deep submersibles. The patent uses plastic film as the compensation method for the compensation membrane. The compensation membrane and the oil-filled box form a built-in pressure compensator. The oil-filled junction box is compensated by the deformation of the compensation membrane. Due to the change of oil volume caused by the pressure change in the metal box, the plastic compensation film used in this patent is easily damaged, resulting in the failure of the pressure compensator, and the redundant compensation method is not used, only the compensation method of the compensation film is used. Once the compensation film A problem will cause the failure of the entire watertight junction box

Embodiment Construction

[0012] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0013] Such as figure 1 , figure 2 , image 3 Shown, the metal box body (1) of the present invention, its four wall surfaces and bottom surface (16) adopt metal plate welding to form. A total of 15 watertight connectors are installed on the wall of the metal box (1), of which the first watertight connector (8) is respectively installed with 6 on the front and rear walls of the metal box (1), 12 in total. Each first watertight connector (8) is installed on the front and rear wall surfaces by 4 bolts (9). In order to ensure the sealing performance of the watertight connector installation, the mounting holes are blind holes. The second watertight connector (10) is respectively installed with 1 on the front and rear walls of the metal box (1), 2 in total, and each second watertight connector (10) is installed on the wall by 4 bolts (11). On...

Abstract

The invention discloses a pressure adaptive watertight connection box of an underwater robot. An oil inlet and an oil outlet are arranged at the bottom surface of a metal box; a flange is mounted at the top end opening of the metal box; a compensation film is placed on the flange; a sealing strip is arranged between the compensation film and the flange; a pressing plate is arranged on the compensation film; a protection cover is mounted on the pressing plate; a watertight connection box is filled with enough compensation oil; the compensation oil and the compensation film form a built-in metal film type pressure compensator; and the built-in metal film type pressure compensator works with a piston type pressure compensator at the same time. The pressure adaptive watertight connection box of the underwater robot does not need to be externally connected with a pressure compensator and an oil path, wherein the piston type pressure compensator makes the oil pressure in the watertight connection box be a little higher than the external water pressure, so that the seawater is effectively avoided being penetrated into the watertight connection box; the titanium film is good in extensibility, large in deformation range and difficult to damage; and the watertight connection box is compact and simple in structure and reliable in operation.

Description

technical field [0001] The invention relates to a watertight junction box, which is used for collecting and connecting underwater electrical circuits, and is suitable for underwater high-pressure environments, especially for various underwater robots working in deep sea. Background technique [0002] Underwater robots play a very important role in the development of marine resources. The watertight junction box is an important and key component of the underwater robot, and generally adopts the structure of an external pressure compensator. The oil-filled watertight junction box communicates with the external pressure compensator through the oil circuit. When under pressure, the external pressure on the watertight junction box and the pressure compensator is greater than the internal pressure, the metal box of the watertight junction box will not be deformed, and the external pressure compensator will be deformed due to external pressure, and the pressure compensator The oi...
