Description
Technical field
The present invention relates to a kind of ring revolving device connecting oceanographic equipment, be specially a kind of ring revolving device with safty device, to ensure the Security of oceanographic equipment connection chain.
Background technique
Along with the development of marine cause, to the monitoring of ocean with detect also day by day by people are paid attention to.In ocean, throw in various detection or monitoring equipment is the most popular method of observing ocean.Meanwhile, due to the high price of oceanographic equipment, the Security of equipment becomes a more serious problem.
In using with regard to current oceanographic instrumentation, oceanographic equipment to transfer with salvaging be all realized by the connection chain in ocean.Now, the quality of connection chain determines the height of device security.
Connection chain is made up of connecting line and ring revolving device.In order to improve the reliability of connecting line, connecting line is added with dual fail-safe.The dual fail-safe of connecting line is realized by the flexible strand in parallel with cable.In ocean, the more difficult fracture of hard cable compared by flexible rope.This guarantees when connecting line disconnects, flexible strand, less than fracture, now, still can pick up equipment by flexible strand.
But equipment is when transferring, salvaging and resting in ocean, and because the reason of current can rotate, at this moment connecting line produces moment of torsion, and when moment of torsion arrives greatly the degree that connecting line can not bear, connecting line will break.In order to the torque on release connection cable, in the connection chain of oceanographic equipment, all employ ring revolving device parts.The use of ring revolving device can discharge moment of torsion, and the moment of torsion reducing connection chain is stressed.
The specific works principle of ring revolving device is such: ring revolving device is connected to the parts between two cables, two cables up and down supposing that ring revolving device connects are A (upper), B (under), B connects deep sea equipment, and A connects the buoyancy aid on other equipment or face, ocean.Because two equipment are in the different degree of depth, the size of current and direction are different, and the speed that so distinct device rotates is different, now connecting line has moment of torsion; Due to the ring revolving device be added with between two cables, the rotary speed difference of two kinds of equipment can be offset, the moment of torsion suffered by release connection cable, so change add the working life just extending cable.Generally, a ring revolving device to all be added to discharge the moment of torsion on cable between every two units.
Because ring revolving device rotates, connection chain only adds dual fail-safe to connecting line, and has not added dual fail-safe to ring revolving device.According to " Bucket Principle ", we know that the quality of connection chain only depends on ring revolving device part the weakest: when ring revolving device breaks down, and connecting line has insurances many be more also futile, equipment still can not salvaged come up.So the reliability of ring revolving device determines the reliability of connection chain.
Summary of the invention:
The technical problem to be solved in the present invention is to provide a kind of ring revolving device with safty device, to ensure the Security of oceanographic equipment connection chain.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of ring revolving device with safty device, comprise ring revolving device body and safty device, described ring revolving device body comprises upper connecting ring for being connected with upper and lower hawser respectively and lower connecting ring, and connecting the rotary component of upper connecting ring and lower connecting ring, change body connecting ring is connected with hawser; Rotating part is connected to upper and lower two rings, and can rotate freely; Described safty device comprise be enclosed within respectively ring revolving device body upper and lower two ends connecting ring safety piece up and down, and for connecting the rope of upper and lower safety piece, safety piece and the coaxial installation of ring revolving device body; When safety piece keeps flat, large steel ring is bottom steel ring, and drum rim is top steel ring, and the top steel ring internal diameter in safety piece is less than the width of ring revolving device body, bottom steel ring internal diameter is greater than the width of ring revolving device body, and the top steel ring of safety piece is connected by link with bottom steel ring.
As further improvement, the width of described ring revolving device body increases to centre gradually from upper and lower two ends.
Described rope is connected on the bottom steel ring of upper and lower two safety pieces.
As preferentially, top steel ring and bottom steel ring form the lower edges face of circular cone, and the circular cone gradient is 40 ~ 60 degree.
Rope described in the present invention connects the bottom steel ring of the safety piece at upper and lower two ends respectively, rope only contact with bottom steel ring, not with ring revolving device body contacts, ensure that safty device are in the process of rotation, rope can not be rubbed.
Two safety pieces in the present invention are connected by rope, and when ring revolving device is normal, upper end safety piece is buckled in ring revolving device body upper end, because the safety piece of lower end is subject to Action of Gravity Field, its not with the lower end in contact of ring revolving device body; When ring revolving device breaks down, ring revolving device is opened the distance of a section very little between connecting ring and lower connecting ring, now rope is in tensioned state, and upper and lower safety piece is all buckled together with the upper and lower end of ring revolving device body, and safty device play the effect of ring revolving device rotary component.
Rope in the present invention, when ring revolving device normal condition, only by the gravity of lower end safety piece; When ring revolving device breaks down situation, be main beaer, carry making a concerted effort of ring revolving device both sides; The preferred hard material of rope, should be excessively not soft, ensure when ring revolving device breaks down, the synchronism that two safety pieces rotate.
Good effect of the present invention is: under the normal service condition not affecting ring revolving device, has set up safty device to ring revolving device; When the rotary component of ring revolving device breaks down, safty device instead of connection and the spinfunction of rotary component, and then ensure the Security of oceanographic equipment connection chain.
