Background of the Invention
Ever since human could travel on the sea, due to technical and economic limitations, human's knowledge to the sea has been often obtained on the ship, which determines that our exploration to the sea is still superficial. With the development of science and technology and upon urgent demands of different countries in the aspects of national security, economy, strategy and the like, exploration to the sea, in particular to deep sea, has a spurt development. As a major means for deep sea observation, studying on the related technologies of the seafloor observatory (also called a submerged buoy) becomes the key of research and development for marine technicians at present.
Popularly speaking, the seafloor observatory is composed of a recoverable unit and a discardable one, and laid at the seafloor by a scientific investigation ship; after finishing a long-term observation task (several months to years), the seafloor observatory receives an unhooking command sent by a ship-borne deck unit so that. its recoverable unit and discardable unit are separated from each other, and finally, the recoverable unit floats upwards to the sea surface by virtue of buoyancy and then can be found and recovered by the researchers, while the discardable unit is left at the seafloor.
In some observation environments, a sensor needs to be mounted in the discardable unit and transmits measurement data to the data acquisition system of the recoverable unit through a cable; in this case, the recoverable unit and the discardable unit cannot be separated by using a conventional unhooking device only; therefore, it is necessary to develop a mechanism that is capable of simply and effectively cutting the cable connecting the discardable part and the recoverable part so that the discardable part and the recoverable one of the seafloor observatory can be separated automatically and effectively.

For easy installation, the blade can be fixed on a blade connecting piece to which the compression springs 13 are fixedly connected, and meanwhile, the depressed clamping grooves are formed in the blade connecting piece.
As shown in Figs. 3 and 4, the strong compression springs 13 arc fixed on a semi-open bracket 14 fixed at the middle lower portion in the blade box 1; a ejection control unit is arranged under and around the semi-open bracket 14; the movable hook 3 is connected with and under die ejection control unit; the ejection control unit includes a pair of rotating rods 15, a pair of supporting plates 16 and a strong torsional spring 17; the pair of rotating rods 15 surround the semi-open bracket 14 and the strong compression springs 13 inside the bracket; each rotating rod 15 is composed of a fixture block 151 of which the top end can be embedded into the corresponding clamping groove in the lower portion of the side surface of the blade 12, and an inverted-L type labor-saving lever, and the inverted-L type labor-saving lever is fixed on the inner side surface of the blade box 1 at the point of inflection and rotates as a whole with the fixed point as an axis; the pair of supporting plates 16 are fixed on the two torsion arms of the torsional spring 17, respectively, and the far ends of the pair of supporting plates are in rotational connection with the bottoms of the rotating rods 15, respectively; the middle of the strong torsional spiing 17 is connected with the movable hook 3 through a steel wire rope.
The blade box, the blade, the strong compression springs, the strong torsional spring, the rotating rods, the shafts and the supporting plates are all made of a titanium alloy material; as a result, when applied to the seatloor observatory, the dual-clamping type cable cutting mechanism can be prevented from being corroded by seawater.
The cable cutting mechanism of the present invention can be applied to the seafloor observatory that is composed of a recoverable unit and a discardable unit which are connected by the cable 4. When the cable cutting mechanism is applied to the seafloor observatory: First, before a seafloor observation experiment, the dual-clamping type cable cutting mechanism is fixedly mounted on a frame between the recoverable unit and the discardable unit of the seafloor observatory; as shown in Fig. 5, the cable 4 connecting the recoverable unit and the discardable unit penetrates through the shallower groove 22 of die cable hold-down plate 2 and is held down by the cable hold-down plate 2, and then goes into a cable connector tube of the discardable unit; the returning device 121 on the side surface of the blade 12 is pulled downwards to compress the compression springs 13 in the blade box 1; meanwhile, the recoverable unit and the discardable unit of the seafloor heat-flow observatory are fixed with a tensioned steel wire rope; the movable hook 3 is hooked up to the tensioned steel wire rope, and the steel wire rope between the hook and the torsional springs is adjusted so that the movable hook 3 can be kept in a tensioned state, and simultaneously, the torsional spring 17 is kept in the tensioned state; the pair of supporting plates 16 is horizontally supporting the tail ends of the rotating rods 15 so that the fixture blocks 151 at the top ends of the rotating rods can be embedded into the depressed clamping grooves formed in the lower portions of the side surfaces of the blade 12 to clamp the ready strong compression spring and the blade, as shown in Fig. 3.
After the seafloor observation experiment is finished, the observatory receives an unhooking command sent by a ship-borne data acquisition control system, and then the steel wire rope fixing the recoverable unit and the discardable unit is turned to a slack state from the tensioned state and the movable hook 3 hooked up to the steel wire rope is loosened and get into the interior of the blade box 1 above; as shown in Fig. 4, under the action of the strong torsional spring 17, the far ends of the supporting plates 16 on the two sides move close to each other, thereby driving the rotating rods 15 connected with the supporting plates to rotate as a whole with the fixed points thereof as axes, and therefore, the pair of fixture blocks 151 at the top ends of the rotating rods 15 come out of the positions of the clamping grooves formed in the lower portions of the side surfaces of the blade 12; at that moment, the strong compression springs 13 rebound to drive the blade 12 above to eject into the deeper groove 21 of the cable hold-down plate 2 to cut off the cable 4 held in the shallower groove 22; as a result, the recoverable unit and the discardable unit of the seafloor observatory are disconnected; finally, the recoverable unit floats upwards to the sea surface by virtue of buoyancy, and is discovered and recovered by scientific research persons, while the discardable unit is left at the seafloor.
