Embodiment 1

[0027] A fuse type release device for underwater anchoring heavy objects, comprising a fuse wire seat 3 and a fuse wire 2, and also includes a fuse wire fixing pole 6, a fuse wire movable pole 7, and a rotating release rod 8, wherein the fuse wire is fixed The support rod 6 is provided with a groove, and one end of the rotation release rod 8 is inserted into the groove of the fuse-wire fixing support rod 6; the fuse-wire movable support rod 7 and the fuse-wire fixing support rod 6 are both provided with fixing bolts. The fuse wire 2 is integrated with the fuse wire holder 3 and fixed in the fixing bolts of the fuse wire movable support rod 7 and the fuse wire fixed support rod 6; one end of the fuse wire holder 3 is connected to the acoustic transponder through a cable.

Embodiment 2

[0029] A fuse-type release device for underwater anchoring heavy objects, similar to Embodiment 1, except that the fuse wire movable support rod 7 and the fuse wire fixed support rod 6 push the spring 5 vertically through the lateral push rod 10 Position; the fuse holder 3 is provided with a fuse 2; the fuse holder 3 is connected to a watertight plug 4; the fuse holder 3 can be fixed with a fixing nut 1; the fuse movable support rod 7 is provided with a limit Bolt 9; the fusing type release device for underwater anchoring heavy objects also includes a weight connecting ring, the weight connecting ring is placed in the rotating release rod 8, the weight connecting ring is connected with the anchor chain; The acoustic transponder is arranged in the frame of the underwater observation system; the fuse release device of the underwater anchoring weight is provided with a housing 11, and a fixing unit 12 using bolts and nuts is provided on the housing 11.

Embodiment 3

[0031] A fuse type release device for underwater anchorage heavy objects, similar to Embodiment 2, except that the number of fuse wires 2 is two, and they are linked by a link rod to form a parallel double release structure; The wires 2 are respectively provided with plugs, and the acoustic transponder is provided with two fuse voltage output sockets, which are respectively connected with the plugs of the fuse wires 2 through cables.

[0032] As in the method of using the fuse release device for underwater anchoring heavy objects described in embodiment 1 or embodiment 2, when the fuse holder 3 is not installed, the fuse movable support rod 7 is located under the elastic force of the spring 5. figure 1 The position of the dotted line is shown. First, make one end of the lateral push rod 10 above the limit bolt 9 of the fuse wire movable support rod 7, so that the rotating release rod 8 is in a vertical free state under its own gravity; then rotate the fuse wire movable support rod...

Abstract

The invention relates to a fuse type release device for heavy objects in an underwater anchorage system and a method for using the same. The wire fixing rod and the fuse wire movable rod are connected by a spring, the fuse wire movable rod is provided with a groove, and one end of the rotating release rod is placed in the groove of the fuse wire movable rod; the fuse wire movable rod and the fuse wire fixed rod Both are provided with fixing bolts, and the fuse wire movable support rod can be pushed by the horizontal push rod, so that the fuse wire seat is fixed in the fixing bolts of the fuse wire movable support rod and the fuse wire fixed support rod; one end of the fuse wire is connected to the acoustic transponder through the cable. connected. It can solve the problem that the fuse wire cannot bear heavy loads, and the invention can realize the release of heavy loads, expand the application range of the electric fuse release technology, and meet the needs of practical underwater applications.

Description

Technical field [0001] The invention belongs to the technical field of underwater observation, and relates to a fuse release device, in particular to a fuse release device for underwater anchoring heavy objects and a use method thereof. Background technique [0002] In order to prevent the deep sea underwater observation system from shifting on the seafloor, usually anchored heavy objects are used to sink the observation system into the seabed, and the heavy weight of the heavy objects makes the observation system fixed on the seabed. When the observation task is completed, use the acoustic communication system to issue a release command on the water surface to separate the mooring weight from the observation system, and then use the positive buoyancy generated by the buoyancy device carried on the observation system to bring the observation system to the surface for recovery; typical Examples of applications include: deep-sea submersible beacons, bottom seabed observation system...
