Referring to fig. 1 to 4, a remote control release system for a life buoy of the present invention includes a support plate 2 for supporting a life buoy 1, the support plate 2 being fixed to one arm of a V-shaped torsion spring 3; the other arm of the torsion spring 3 is fixed on the bracket 4; when the support plate 2 is in a horizontal state, the lifebuoy 1 is horizontally fixed.
One end of the supporting plate 2 is fixed at one end of an annular rope 5; the other end of the annular rope 5 is sleeved with a movable iron core 6 arranged in a remote control release device 7 positioned above the supporting plate 2, and the supporting plate 2 is kept horizontal through the tension of the annular rope 5; the annular rope 5 can be pressed and fixed by an annular rope fixing nut 51 arranged on the support plate 2 or directly sleeved in the annular rope 5.
A coil 10 is arranged in the remote control release device 7, and the movable iron core 6 is arranged in the coil 10; the movable iron core 6 is connected with the spring 11 and is in an extending state under the action of the spring 11; the coil 10 is connected to a power supply which controls the on-off state through a remote control button 71 through a lead; when the coil 10 is electrified, the movable iron core 6 retracts under the action of the electromagnetic force of the coil 10, the annular rope 5 is separated from the movable iron core 6, the support plate 2 rotates downwards under the action of the torsional force of the torsional spring 3 and is in an inclined state, and the life buoy 1 can slide down; when the coil 10 is powered off, the movable iron core 6 is restored to the extended state by the restoring force of the spring 11. To enable manual operation, the plunger 6 is further connected to a manual release lever 72, which is swung to move the plunger 6.
In order to prevent the annular rope 5 from being separated, when the movable iron core 6 extends out, the movable iron core 6 is vertically and tightly attached to an annular rope limiting plate 8.
If the power supply required by the remote control release 7 is dc, a power conversion box 16 for converting ac into dc can be connected between the ac power supply and the coil 10.
A life buoy limit plate 9 used for limiting the life buoy 1 to move towards the direction departing from the annular rope 5 is fixed on the support 4.
The rotation of the support plate 2 can be achieved by: one end of the supporting plate 2, which is far away from the annular rope 5, is fixed on the life buoy limiting plate 9 or the bracket 4 through the rotating shaft 21. The rotation shaft 21 is disposed in the loop of the torsion spring 3 and restricts movement of the loop.
The remote release 7 will be described in more detail below.
