The fixed foot 12 is fixed around the placement bottom plate 11, and the fixed foot 12 can be fixedly installed on the ship in any form, which is used for bottom support; the guardrail 13 is fixed at the left and right ends of the placement bottom plate 11, and the guardrail 13 is made of a plurality of rods welded together and is in the shape of a right-angled trapezoid, which plays a protective role. The life raft 2 includes a raft shell and a raft body, and the raft body is arranged in the raft shell, and the raft shell is tied to the placement bottom plate 11. The two ends of the tying rope 3 are connected and fixed to the raft frame 1 after passing through the middle position of the life raft 2, so that the life raft 2 is tied to the placement bottom plate 11 of the raft frame 1. The releaser 4 is a conventional product on the market, which is connected to the tying rope 3; at this time, the tying rope 3 is an easy-to-break rope. The telescopic push rod 5 is a pneumatic telescopic rod, one end of which is fixed or hinged to the guardrail 13 of the raft frame 1, and the other end is against the raft shell. The control system is respectively connected to the releaser 4 and the telescopic push rod 5 for overall control and adjustment; a remote controller can be provided, and the buttons on the remote controller can be used to control the releaser 4 and the telescopic push rod 5 to work respectively. The control system controls the releaser 4 to cut the tying rope 3 and controls the telescopic push rod 5 to extend, thereby pushing the life raft 2 to rotate and release relative to the raft frame 1, that is, pushing the life raft 2 from the raft frame 1 into the sea.
[0028] In this embodiment, the device further comprises a push block 6, which is a steel structure. The push block 6 is fixed on the hull of the life raft 2 in any fixing form. One end of the telescopic push rod 5 is fixed or hinged to the guardrail 13, and the other end is against (or in active contact with) the push block 6. The push block 6 is not limited to a specific structural shape, so that the telescopic push rod 5 can push the life raft 2 into the water; the push block 6 can be a welded right-angle steel plate structure, with a push groove 61 on the surface, and the push groove 61 is a rectangular groove or a U-shaped groove. One end of the telescopic pushing rod 5 is fixed or hinged to the guardrail 13, and the other end is movably arranged in the pushing groove 61; when the telescopic pushing rod 5 is extended, that is, the extended end of the telescopic pushing rod 5 extends to push the pushing block 6, the extended end of the telescopic pushing rod 5 directly pushes the pushing groove 61 (that is, the pushing block 6), or slides downward along the pushing groove 61 and pushes the pushing block 6, thereby pushing the life raft 2 from the placement bottom plate 11 of the raft frame 1 into the water; the setting of the pushing groove 61 facilitates the movable contact between the telescopic pushing rod 5 and the pushing block 6, and facilitates pushing the pushing block 6 or pushing the life raft 2.
[0029] In this embodiment, two sets of telescopic push rods 5 are respectively provided at the left and right ends of the life raft 2 in parallel, so as to facilitate pushing the life raft 2 .
[0030] In actual application, the principle of the releaser 4 cutting the binding rope 3 is as follows: the releaser 4 contains structures such as a spring, a blade and a resistor. When the remote control button is pressed, a voltage will be given to make the resistor in the releaser 4 overvoltage and overload, and then the spring will be released to push the blade, and the blade will cut the rope.
[0031] In actual application, the raft shell is composed of two buckled (or hinged in the middle) shells. There is a fixing ring on the bottom plate 11 of the raft frame 1, which is connected to the cylinder quick-release valve on the raft body in the raft shell. When the life raft 2 is pushed off the raft frame 1 and falls into the water, the quick-release valve will be pulled to start the cylinder. At the same time, the two shells will separate, and the raft body in the shell will detach from the raft shell and fall into the water. The raft body will automatically inflate and take shape for the corresponding personnel to ride.
[0032] In practical applications, the raft frame 1, the life raft 2 (raft shell, raft body), and the releaser 4 are all existing technologies and will not be described in detail.
[0033] The working principle of this embodiment is: the releaser 4 is controlled by the control system (or by the remote control button) to cut the tying rope 3, and the telescopic push rod 5 is controlled to extend, thereby pushing the life raft 2 to rotate and release relative to the raft frame 1, and the life raft 2 is pushed into the water to be automatically inflated and formed.
[0034] The beneficial effects of this embodiment are: the device can automatically release the life raft 2, has high release efficiency, is easy to use, simple to operate, and has strong applicability.
