Detailed Implementation

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] The present invention provides a deep-water buoy separation actuator, including a column 1, on which two or more clamping mechanisms 3 are uniformly installed circumferentially at the upper end of the column 1.

[0028] The clamping mechanism 3 includes a support rod 31 and a clamping part. The support rod 31 and the clamping part are connected by a first explosive bolt 33. The clamping part is used to clamp the buoy 2 and can separate itself and release the buoy 2 by means of a second explosive bolt 37.

[0029] Specifically, the clamping part includes three or more arc-shaped plates, and adjacent arc-shaped plates are fixed together by second explosive bolts 37 to form a closed loop.

[0030] In this embodiment, as Figure 1 , Figure 2 , Figure 3 As shown, four clamping mechanisms 3 are arranged in a circular array on the upper end of the column 1. The clamping part includes three one-third arc-shaped plates, namely a first connecting plate 34 and two second connecting plates 35. An extension rod end 32 is welded on the first connecting plate 34. A second connecting plate 35 is installed at each end of the first connecting plate 34, and the two second connecting plates 35 are connected end to end. A cover plate 36 is provided at one end of each of the first connecting plate 34 and the second connecting plate 35. A through hole is opened on the surface of the cover plate 36, and a screw hole corresponding to the through hole is opened at the other end of the first connecting plate 34 and the second connecting plate 35. Second expansion bolts 37 are installed in the holes (through holes and screw holes) opened between the first connecting plate 34 and the cover plate 36 and between the second connecting plate 35 and the cover plate 36. Figure 5 , Figure 6 As shown.

[0031] As an improvement, such as Figure 4 As shown, the protruding rod end 32 on the first connecting plate 34 is in the shape of a two-stage step. The end of the support rod 31 matches the profile of the protruding rod end 32. After the end of the support rod 31 and the protruding rod end 32 are engaged, both steps are fixedly connected by the first expansion bolt 33. The staggered arrangement of the support rod 31 and the protruding rod end 32 facilitates positioning and increases the stability of the connection between the support rod 31 and the protruding rod end 32.

[0032] The first explosive bolt 33 and the second explosive bolt 37 are identical in structure. As shown in the figure, the first explosive bolt 33 comprises a fixing cap 332, a sealing ring 334, a sealing sleeve 335, a main body 336, an electric detonation tube 337 and a piston assembly 338. Figure 7

[0033] The electric detonation tube 337 is installed in the middle of the main body 336, one end of the main body 336 is connected with a threaded separation part, and a weakened groove is arranged at the connection between the main body 336 and the threaded separation part 13. The piston assembly 338 is installed in the inside of the main body 336 close to the threaded separation part, and the piston assembly 338 is located at the end of the electric detonation tube 337. A conical piston limiting platform is arranged at the front end of the piston assembly 338, which is used to limit the piston assembly 338 after moving to the position and abutting against the end face of the main body 336. The sealing sleeve 335 is installed at the end of the electric detonation tube 337 away from the piston assembly 338, and the sealing plug 333 is installed in the inside of the sealing sleeve 335. The sealing sleeve 335 is used to seal the space between the sealing plug 333 and the main body 336, and the sealing plug 333 is electrically connected with the external ignition cable. The fixing cap 332 is installed at the end of the main body 336, which is used to limit the sealing plug 333. The sealing ring 334 is installed in the groove on the outer surface of the sealing sleeve 335, the electric detonation tube 337 and the piston assembly 338, and the sealing ring 334 is in contact with the inner surface of the main body 336, so as to seal the sealing sleeve 335 and the main body 336, the electric detonation tube 337 and the main body 336, and the piston assembly 338 and the main body 336.

[0034] When the electric detonation tube 337 is connected with the ignition cable through the sealing plug 333, the electric detonation tube 337 is fired and moves with the piston assembly 338. After the piston assembly 338 moves to the position, the conical piston limiting platform abuts against the main body 336 to limit the position. The end of the piston assembly 338 makes the threaded separation part of the main body 336 fall off from the position of the weakened groove, so as to realize the explosion of the first explosive bolt 33 (and the second explosive bolt 37).
