Unmanned underwater vehicle folding swim bladder deepwater floating-upward test device and method

Abstract

The present invention discloses an unmanned underwater vehicle folding swim bladder deepwater floating-upward test device and method. The device comprises a deepwater environmental simulation pot, a pressurization gas bottle and an external test control device. The deepwater environmental simulation pot is provided with an inlet valve, a vent valve, an internal observation device and a pressure sensor, the inlet valve and the vent valve are both solenoid valves and the internal observation device, the pressure sensor, the inlet valve and the vent valve are electrically connected with the external test control device. The unmanned underwater vehicle folding swim bladder deepwater floating-upward test device and method employ the deepwater environment simulation pot pressuring mode to effectively simulate the deepwater environment and provide a research means for the development of the process research in the deepwater environment of a fairing and the swim bladder; the unmanned underwater vehicle folding swim bladder deepwater floating-upward test device and method employ the mode of the combination control of the pressure sensor and the vent valve to allow the pressure in the pot to be reduced in the linear mode and effectively simulate the water pressure changing environment of the deepwater floating-upward process so as to provide a simulation means for the deepwater floating-upward exhaust process of the swim bladder; and moreover, the internal observation device is arranged in the deepwater environment simulation pot to allow the deepwater floating-upward research to be visualized and quantified.

Description

technical field [0001] The invention belongs to the field of marine technical equipment, and in particular relates to a deep-water flotation test device and a test method for a folding floating bag of an unmanned submersible vehicle. Background technique [0002] Deep-water unmanned submersibles need to float and recover at different navigation depths. Floating bag inflatable recovery is a commonly used recovery method. When the unmanned submersible vehicle is sailing, the floating bag is folded and stored in the fairing. After receiving the command to float up, the floating bag starts to inflate and opens the fairing. When the pressure in the bag reaches the specified pressure, the floating bag is driven by its own buoyancy. The unmanned underwater vehicle floated up to complete the recovery. [0003] In the existing technology, the deep water flotation test of the floating bag cannot be completed in the laboratory because the water depth of the test pool is not enough, or...
