Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] like figure 1 As shown, the water hydraulic system in the embodiment includes a power source, a submersible buoyancy and attitude adjustment system, working tools and systems.

[0025] The power source is used to drain the water ballast tanks 1 and 4 to realize the adjustment of buoyancy, pitch and heel of the submersible, and at the same time provide pressure water to the working tools and system to drive the manipulator and tools to complete the work. It includes a motor 15 , a hydraulic pump 14 , a safety valve 13 , an electromagnetic switch valve 12 , a pressure sensor 16 , an inlet filter 9 , an outlet filter 17 and an electromagnetic reversing valve 10 . The electromagnetic reversing valve 10 is a three-position four-way reversing valve. When the power source is not working, the electromagnet is de-energized, and the electromagnetic valve ...

Abstract

The invention provides a water hydraulic system of a multifunctional submersible. The water hydraulic system comprises a power source, a flotage and posture regulating mechanism and an operating mechanism, wherein the power source mainly comprises a motor, a hydraulic pump and a solenoid directional valve; the flotage and posture regulating mechanism mainly comprises a plurality of water ballast tanks and balanced valves; through injecting water into and draining off water from different tanks, not only the flotage regulation on the submersible is realized, but also trim control and heel control are realized, so that the single independent systems for flotage regulation and trim and heel control are integrated into a unified system; and in addition, under the matching of all the valves, the operating mechanism can be driven to finish underwater operation. The water hydraulic system can provide water sources of different flow and pressure so as to meet the requirements of different types of working tools on the power source; and meanwhile, the water hydraulic system enables flotage regulation and trim and heel control to have different performances in different water depths, namely the water hydraulic system can meet deep-depth applicability and shallow-depth fast response.

Description

technical field [0001] The invention belongs to the field of submersibles, and in particular relates to a water hydraulic system of a multifunctional submersible. Background technique [0002] Submersibles are important equipment for efficient exploration, scientific investigation, development operations, military detection and combat platforms. Submersibles need to complete different tasks underwater, such as cutting, cleaning, grinding, cutting, drilling, and loading and unloading of connectors for underwater steel cables and flexible cables, or completing the collection of underwater samples. deployment and other tasks. [0003] After the submersible takes a sample, the density of seawater changes due to the increase in weight or the decrease in weight after releasing other equipment, or due to the characteristics of the water medium (pressure, temperature); and with the increase of the diving depth, the pressure resistance of the submersible The elastic deformation of ...
