Problems solved by technology

The tension leg platform used in sea surface operations can be fixed by the tension leg cable. However, the tension of the current tension leg platform is mostly provided by the buoyancy generated by the buoy installed under the cap of the tension leg platform. The buoy increases to a certain extent. The stre

Embodiment Construction

[0015] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0016] The invention provides a tethered balloon system for marine environment monitoring, such as figure 1 As shown in Fig. 1, a triangular tension leg platform is used as the mooring system to connect with the tethered balloon, so that the tethered balloon is limited to float within a certain range. The upper surface of the tethered balloon 1 is loaded on the solar panel, and the monitoring equipment 4 is loaded inside the tethered balloon 1 .

[0017] The implementation of the present invention mainly includes four stages, namely the preparation, release, floating and recovery stages of the tethered balloon. In the preparation stage, the suction foundation 8 is installed by negative pressure sinking, and the other end of the tension leg steel cable 7 connected to the suction foundation 8 is connected to the tripod cap 5 and fixed according to a predete...

Abstract

The invention discloses a tethered balloon system used for marine environmental monitoring. The tethered balloon system can fixedly float in the sea to achieve monitoring and is good in stability performance and easy to transport, install and recycle in the sea. Floating of a tethered balloon is limited within a certain range through a tension leg platform. When the tethered balloon does not rise to a predetermined height yet, buoyancy force produced by gas stored in a compressed gas bag can guarantee normal working of the tension leg platform. When the tethered balloon rises to the predetermined height and starts to perform monitoring, lift force of the tethered balloon provides tension required by stabilization of the tension leg platform, and therefore the design of a pontoon is omitted. Meanwhile, upward traction borne by the tension leg platform can relieve the influence on a bearing platform by a transverse wave load, and therefore the stability of the bearing platform is improved. Besides, the compressed gas bag can be used for storing a certain amount of helium gas, so the height of the tethered balloon is reduced, the tethered balloon is convenient to maintain and recycle, maintenance difficulty and recycling difficulty are lowered, and the helium gas in the tethered balloon can be recycled.

Description

technical field [0001] The invention relates to the technical field of marine environment monitoring, in particular to a tethered balloon system for marine environment monitoring. Background technique [0002] With the depletion of land resources, the exploration and development of marine resources have attracted more and more attention. Due to the high cost of aircraft and satellites and their close relationship with weather conditions, how to arrange instruments and equipment in the ocean with low cost and high economic benefits will become a new direction for future exploration. As a stable and reliable floating platform, tethered balloons can fill the gaps between aircraft and satellites in time and space. They are very suitable for carrying various electronic instruments and equipment, and have broad application prospects in both military and civilian applications. Because of its long blanking time, large coverage area, low energy consumption, easy disassembly, and str...
