Embodiment 1

[0025] see Figure 1-Figure 4 , a foldable antenna device for an underwater glider, including a fuel tank 1, a telescopic antenna 2, an extended oil inlet pipeline 3, a rewinding oil return pipeline 4, an oil pump 5, and a pressure relief solenoid valve 6.

[0026] Stretching oil inlet pipeline 3 and retracting oil return pipeline 4 are connected between fuel tank 1 and telescopic antenna 2 . Oil tank 1 stores hydraulic oil. The extended oil inlet pipeline 3 is a passage for hydraulic oil to be transported from the oil tank 1 to the telescopic antenna 2;

[0027] The oil pump 5 is installed in series in the extended oil inlet pipeline 3, and is used to provide power for the hydraulic oil to flow from the oil tank 1 to the telescopic antenna 2; the pressure relief solenoid valve 6 is installed in series in the rewinding oil return pipeline 4, and is used to control Turn on and off the oil return pipeline 4. The pressure relief solenoid valve 6 controls the rewinding oil retu...

Embodiment 2

[0030] An underwater glider comprises a glider body, which is an assembly of parts with basic working performance of the underwater glider. The folding antenna device described in Embodiment 1 is installed inside the glider body.

[0031] Specifically, the glider body has a shroud 7, a sealed cabin 8, and a drive system. In this embodiment, the sealed cabin 8 is a cabin inside the pressure-resistant shell, and the shroud 7 is a flow guide connected to the tail of the pressure-resistant shell. The cover, the drive system is the power drive system of the glider. The drive system includes an oil tank 1 and an outer oil bag 9 communicating with the oil tank 1 through an oil delivery pipe 10. The oil tank 1 is installed in the sealed cabin 8, the outer oil bag 9 is installed in the shroud 7, and the oil delivery pipe 10 runs through the pressure-resistant casing. The rear end shell is sealed with the rear end shell.

[0032] The retractable antenna 2 of the folded antenna device ...

Abstract

The invention discloses a foldable antenna device for an underwater glider and an underwater glider, belonging to the technical field of underwater robots, and is characterized in that it includes a fuel tank, a telescopic antenna, an extended oil inlet pipeline, a retractable oil return pipeline, an oil pump, Pressure relief solenoid valve; the extended oil inlet pipeline and the retractable oil return pipeline are connected between the fuel tank and the telescopic antenna; the oil pump is installed in series in the extended oil inlet pipeline; the pressure relief solenoid valve is installed in series in the retracted oil return pipeline Middle; the telescopic antenna includes a helical reed, a flexible oil pipe and a flexible antenna, the flexible oil pipe is installed on the helical reed and arranged along the length direction of the helical reed; the flexible antenna is installed on the helical reed and arranged along the length direction of the helical reed, the flexible oil pipe and the The extended oil inlet pipeline is connected with the retracted oil return pipeline. The antenna device has a retractable function, not only has good communication performance, but also can completely eliminate the resistance of the antenna when the underwater glider travels, and at the same time avoid damage to the antenna.

Description

technical field [0001] The invention belongs to the technical field of underwater robots, and in particular relates to a foldable antenna device for an underwater glider and the underwater glider. Background technique [0002] An underwater glider (UG) is an intelligent underwater robot that can perform tasks in a complex ocean environment. By changing the net buoyancy and adjusting the attitude angle, a pair of fixed wings are used to generate propulsion, and its energy consumption is extremely small. , can realize zigzag profile movement in the ocean, so it has the working characteristics of low power consumption, long battery life, and ultra-quiet. The underwater glider has low manufacturing cost and maintenance cost, is reusable, and can be released in large quantities, which meets the needs of long-term and large-scale ocean exploration. [0003] While underwater glider technology is gradually maturing, new problems are constantly emerging. With the continuous increas...
