Piston type buoyancy adjusting mechanism of underwater lifting platform

Abstract

The invention relates to a piston type buoyancy adjusting mechanism of an underwater lifting platform. The buoyancy adjusting mechanism comprises thrust springs, pistons, elastic rubber films, connecting parts, cylinders, push rods, screw rods, screw rod driving mechanisms and positioning guide rails, and peripheral equipment comprises an underwater platform and a control system, wherein the buoyancy adjusting mechanism is positioned in the underwater platform, the outer circle of the underwater platform is provided with two symmetrical piston holes which are stepped holes, the hole of each stepped hole communicated with the outer circuit is larger than an inner hole, and elastic rubber films are fixedly connected onto the stepped end surfaces of the stepped holes by the connecting parts; the thrust springs are sheathed on the outer circles of the pistons and are mounted in the inner holes of the piston holes, the two pistons are in contact with each other, and the central axis of the underwater platform is positioned on the contact surface between the pistons; and the screw rod driving mechanisms are positioned below the pistons, the screw rods on the screw rod driving mechanisms are sheathed with the push rods, both sides of each push rod are provided with the positioning guide rails, and the push rods coincide with the central axis of the underwater platform. The piston type buoyancy adjusting mechanism of an underwater lifting platform in the invention is applicable to the marine environmental monitoring field, and has the advantages of high buoyancy adjusting capability and high operational reliability.

Description

technical field [0001] The invention relates to an underwater buoyancy adjustment mechanism, in particular to a buoyancy adjustment mechanism for a piston-type underwater lifting platform, which belongs to the field of marine environment monitoring. Background technique [0002] In the past, the marine environment monitoring platform systems at home and abroad generally used mooring to keep the main system of the platform at a certain depth in the water, and the communication buoy was carried on the main body of the platform; The communication buoy is released at all times and floats on the water surface for a long time, thus forming an underwater communication link, and the underwater environment information monitored by the platform system is sent to the outside world through this communication link. However, this working method has its limitations. It can only carry out environmental monitoring at fixed-point locations, and the monitoring range is very limited. Moreover,...

Problems solved by technology

But this way of working has its limitations. It can only carry out environmental monitoring at fixed-point locations, and the monitoring range is very limited.

Moreover, buoys floating on the water surface for a long time are easily damaged due to sea wind waves, tides, long-term sunlight exposure, different seasons and the influence of day and night temperature changes, and human factors. Usually, considerable manpower and ships are required to monitor or Inspection and maintenance costs are considerable

[0003] The recent patent document ZL 200620098049.1 discloses an oil-gas bag combined floating platform, which overcomes the above-mentioned shortcomings, thus opening up a new path for the development of marine environment monitoring platforms; however, everything cannot be perfect, and the The invention itself also has deficiencies, such as: relatively complex structure of the oil-air bag combination, slow reaction speed, slow pressure leakage in the pipeline and other defects that are difficult to completely solve so far. In view of these deficiencies, the present invention is proposed at this point
