Embodiment Construction

[0010] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0011] combine figure 1 and figure 2 , the present invention includes a support 1 and a buoyancy block 2 installed on the upper end of the support 1. Due to the positive buoyancy provided by the buoyancy block 2 for the present invention, it can float to the water surface. The body is connected, and the bottom of the support 1 is connected with a tether cable 10, and the other end of the tether cable 10 is connected to the AUV body, and the tether cable 10 is arranged in a serpentine shape in the AUV body. Chemical fiber material, so that it can have positive buoyancy in water, and will not hinder the floating of the present invention. The length of the mooring cable 10 should have a certain margin, which should be greater than 1.2 times the water depth of the working sea area. When the present invention floats, the serpentine arran...

Abstract

The invention provides an AUV emergency alarm buoy. The buoy can be released when an AUV is trapped underwater and positioning and alarm can be performed through the buoy. The AUV emergency alarm buoy comprises a support, a buoyancy block, a power supply system, a control system, a stroboscope lamp, a positioning antenna, a communication antenna, a depth gauge, an electric explosive bolt and a mooring line. The buoy is provided with a power supply which is independent of the AUV, the power supply supplies power for the control module, the stroboscope lamp and the depth gauge, the buoy is fixed to the AUV body through the electric explosive bolt, the buoyancy block is used for providing positive buoyancy, and the buoy can float upwards to the water surface after the electric explosive bolt is exploded, so that people can figure out the position of the device. After floating upwards, the buoy is still connected to the AUV body through the mooring line, and thus rescue can be carried out. The AUV emergency alarm buoy is compact in structure design, low in cost and applicable to being installed and used in AUVs which work near the bottom or at offshore sea having more foreign objects in water.

Description

technical field [0001] The invention relates to a buoy, in particular to an AUV emergency alarm buoy. Background technique [0002] Unmanned submersible AUV can be widely used in seabed biological resource exploration, mineral resource sampling, seabed topographic survey, sunken object salvage, seismic geothermal activity monitoring, marine environment monitoring, marine engineering maintenance, etc. However, the loss of AUV has brought huge losses, which has become a problem that plagues various AUV research and development and application institutions at home and abroad, and also hinders the promotion and application of AUV. [0003] Generally speaking, AUVs have positive buoyancy. If the control system collapses, the AUV that loses power will eventually surface. However, if the AUV is trapped underwater or the cabin is flooded, the AUV will not be able to float to the surface naturally. In this case, people cannot determine the position and status of the AUV on the wate...
