Problems solved by technology

[0003] The passive cable take-up method is simple to operate, but the cable is placed in a mess after being recovered, and the storage space of the cable cannot be effectively used. At the same time, it is also easy to cause the cable to loosen due to the buoyancy of the cable in the water and the change of the cable’s own tension. twine
In terms of the layout of the cable quilt, the traditional active cable retracting method has greatly improved compared with the passive cable retracting method, but the arrangement is not neat and compact enough, and the cable storage space has not been effectively utilized; The retracting mechanism may be impacted by a sudden tension of the cable

Embodiment Construction

[0042] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0043] The present invention is made up of cable 4, recovery device 15 and release device 23 (as shown in accompanying drawing 1-1), and wherein recovery device 15 and release device 23 are respectively arranged in different positions (as on the deck) on the carrier, they form cost The main body of the invention; one end of the cable 4 passes through the release device 23 and is wound inside the recovery device 15 . The recovering device 15 is mainly used for recovering, storing and arranging the cables 4 , and the release device 23 is mainly used for releasing the cables 4 and applying tension to the cables 4 .

[0044] Recovery device 15 is mainly made up of cylinder 3, recovery frame 9, power slide block 10 (as accompanying drawing 1-1,1-2,2-1,2-2,3-1,3-2,4,5- 1, 5-2, 6-1, 6-2, 7-1, 7-2), the power slider 10 is installed inside the recover...

Abstract

The invention discloses an underwater cable folding and unfolding device, it consists of cable, unfolding equipment and folding equipment, among them the unfolding equipment and folding equipment compose the main body of the invention; one end of cable is twined in the folding equipment interior after passing through the unfolding equipment. The invention can ensure cable is arranged in the cable storing space ordered, uniformly and densely in underwater environment, and avoid cable twined each other due to the attack of water flow in the folding and unfolding course, and also can reduce cable stretching force changing and release the attack to folding and unfolding device from cable.

Description

technical field [0001] The invention relates to an underwater cable retractable mechanism, in particular to a cable retractable mechanism suitable for the recovery and derivation of various flexible cables in an underwater environment. Background technique [0002] The underwater cable retracting mechanism can be roughly divided into two methods: passive cable retraction and active cable retraction; passive cable retraction means that the cable is scattered together by its own gravity and tension after being recovered; The cables are wound on the rotating body in a disorderly manner under the action of tension; these two types of cable retracting mechanisms rely on the traction force at the end of the cables to pull the cables to complete the cable release action. [0003] The passive cable take-up method is simple to operate, but the cable is placed in a mess after being recovered, and the storage space of the cable cannot be effectively used. At the same time, it is also e...
