Big specific capacity buoyancy force adjustment and emergency self-rescue integrated device and submersible machine

Abstract

The invention discloses a big specific capacity buoyancy force adjustment and emergency self-rescue integrated device and a submersible machine. The integrated device includes a water chamber (1), atleast one machine pump valve assembly (3), a detection module and a control module (2); one port of the machine pump valve assembly (3) is communicated with a sea connection port of the submersible machine, and the other port is communicated with the water chamber (1) to achieve injection and discharging of sea water; the detection module and a machine pump assembly (8) are electrically connectedwith the control module (2) separately; the detection module sends detected signals to the control module (2), and the control module (2) controls the machine pump valve assembly (3) to be switched onor switched off to achieve buoyancy force adjustment according to the signals. The big specific capacity buoyancy force adjustment and emergency self-rescue integrated device and the submersible machine have the advantages that not only can the normal buoyancy force adjustment operation capability of the amphibious submersible machine be ensured, but also it can be ensured that the submersible machine can safely float up to be recycled under an emergency situation.

Description

technical field [0001] The invention belongs to the technical field of submersibles, and in particular relates to a large specific capacity buoyancy adjustment and emergency self-rescue integrated device and a submersible. Background technique [0002] As one of the main technological means for human beings to develop and utilize the ocean, submersibles have become an important frontier of marine high-tech. A large number of submersibles have emerged one after another, including manned submersibles (HOV), cable-operated remote-controlled unmanned vehicles (ROV), and cable-free autonomous unmanned submersibles (AUV). These submersibles, such as AUV, are at most cruising near the seabed or on standby at the bottom, and cannot maneuver freely on the seabed. However, crawler ROVs that can operate on the seabed need umbilical cables to supply power on the water surface, so there is no multi-dwelling submersible that has both seabed movement and water floating functions in the wo...

AI Technical Summary

Problems solved by technology

[0006] 2. The adjustment method is relatively backward: at present, the buoyancy adjustment system of submersibles developed at home and abroad mainly has three forms in terms of working forms: load dumping, oil bag and water injection

This method requires the use of solenoid valves or hydraulic oil circuit control valves for reversing, which increases the difficulty of integrating the buoyancy adjustment system

[0007] 3. The installation and arrangement are more troublesome: most conventional submersibles are horizontal-vertical three-dimensional layout space, and the space between the inner and outer balls of spherical submersibles is a special-shaped space, and the installation and arrangement of buoyancy adjustment devices are difficult

[0008] 4. The self-rescue design is unreasonable: when the amphibious submersible has a serious failure or emergency condition on the seabed, it is difficult to ensure that the entire submersible is separated from the seabed by means of fixed dumping

This self-rescue method is poor in stability and irreversible, and cannot be used efficiently and repeatedly
