A buoy throwing and releasing device

Abstract

The invention provides a buoy throwing and releasing device, which can eject buoy projectiles out of the underwater mooring platform when the underwater mooring platform is in any posture. The buoy load-throwing release device includes a casing, a transfer box, a spring I, a spring II, a shaft push spring, an actuator, a piston rod, a wedge block and a connector. The device is installed in the hole seat of the shell of the underwater mooring platform, and a sealing ring is used to ensure the sealing between the buoy load-throwing release device and the shell. When the actuator starts, the satellite position-indicating buoy is ejected out of the mooring platform shell under the action of the spring force, and the satellite position-indicating buoy emerges from the water under the action of its own positive buoyancy, and sends the current position information. The invention is triggered by a small actuator and moves quickly; the release shaft adopts a double sealing structure, which can ensure the sealing before and after the action of the device, so as to ensure that the interior of the underwater mooring platform is always in a sealed state; the double spring design is adopted, and the mooring platform can be in any posture of the mooring platform. The satellite position-indicating buoy can be dropped and released.

Description

technical field [0001] The invention relates to a release device, in particular to a buoy load-throwing release device, and belongs to the technical field of mechanical design. Background technique [0002] When the underwater anchoring platform completes the task and rises to the surface, it needs to send the current position information (ie position indication) to guide the mother ship to come and recover the platform. At present, the position indication method at home and abroad mainly obtains the current position information through satellite signals such as GPS or Beidou, and then transmits it to the mother ship through the data link. The traditional position-indicating device is fixedly installed on the underwater mooring platform. In order to avoid the negative effects of ionization and shielding caused by seawater, most of the antennas of the position-indicating device need to extend out of the platform to a certain height. Adversely affect the fluid profile of the ...

Problems solved by technology

The traditional position indicating device is fixedly installed on the underwater mooring platform. In order to avoid negative effects such as ionization and shielding brought by seawater, the antennas of most position indicating devices need to extend out of the platform to a certain height, and the position indicating device extending outside the platform will Detrimental effect on the fluid profile of the mooring platform

[0003] At the same time, for a certain type of cylindrical revolving platform whose attitude will be deflected when out of the water, the antenna position of the satellite position-indicating buoy may face the sky or be buried underwater after the water is out, so that the position-indicating buoy cannot emerge from the water, and thus cannot Send current position information to mother ship
