Any one of a locator, a flash lamp and a buzzer can be arranged on the buoy 5, and two of the locator, the flash lamp and the buzzer can be combined or the three can be combined.

As shown in fig. 1 to 6, the working process of the present invention is explained in detail as follows:

the buckle 8 on the connecting rope 1 is buckled on the body of the fire rescue boat, and the buckle 8 on the mounting belt is buckled on an outer machine of the fire rescue boat. When the fire rescue boat normally works, the air bag 3, the exciter 7, the air supply device 6 and the buoy 5 are accommodated in the accommodating bag 2. The storage bag 2 is hung on an external unit.

When the outer machine breaks away from hull, connect rope 1 and receive the pulling force, by exciter 7 in the unthreaded hole outer pulling collecting bag 2, exciter 7 arouses air feeder 6, along with inflating of air feeder 6, gasbag 3 expands rapidly in collecting bag 2, struts collecting bag 2 and suspends on the surface of water. The outer machine is hung on the air bag 3 through a mounting belt to avoid sinking. The buoy 5 floats on the water surface and is matched with the air bag 3 to serve as a reference object.

When the pulling force of the outboard motor to separate from the hull is too large (exceeding the bearing limit of the rope socket 15), the first rope segment 16 and the second rope segment 14 of the connecting rope 1 are separated, so that the damage of the too large pulling force to the hull can be avoided. When the external machine needs to be abandoned temporarily, the connecting rope 1 can be disconnected from the rope sleeve 15.

According to stress analysis, the buoyancy of the air bag 3 can bear an outdoor unit within 70kg, and the air bag can be suitable for most outdoor units in the market, and the outdoor unit is driven to suspend in water after being separated. Even if the fishing is not carried out immediately, the outer machine can be ensured not to sink in a short time. Along with the lapse of the submergence time, the gas in gasbag 3 can reduce gradually, even the outer machine sinks at the bottom, also sinks slowly, can reduce the damage that the outer machine received. The length of the connecting line 4 is long enough, for example, 10 to 100 meters, and even if the airbag 3, the exciter 7, the air supply device 6, the connecting rope 1, the storage bag 2, the mounting belt, and the outdoor unit are all sunk, the buoy 5 can always float on the water surface, thereby providing a reference for the subsequent search of the outdoor unit.

It will be appreciated by those skilled in the art that the utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or are equivalent to the scope of the utility model are intended to be embraced therein.
