Embodiment
[0026] Example: such as figure 1 As shown, it is the initial state of the device: the detector, the controller and the linear motor 21 form a circuit loop. The output shaft of the linear motor 21 and the conical sealing cover 22 are connected together through the coupling 20. In the initial state, the conical sealing cover 22 blocks the opening of the free water sealing plate 2, and the free water sealing plate 2 is stuck in the free water sealing board mounting slot 28. A free water sealing plate sealing ring 19 is installed between the free water sealing plate 2 and the hydraulic cylinder 18 to ensure that the free water 1 will not flow into the cavity area where the solid calcium oxide 3 is located in the initial state. Ammonium nitrate 16 is placed in the cavity area between the piston 5 and the heat transfer plate 4, and the heat transfer plate 4 is snapped into the heat transfer plate installation groove 27. Similarly, the piston 5, the heat transfer plate 4 and the hyd...

The invention relates to an instantaneous expansion self-recovery type upward floating device for an all-sea-depth autonomous sampler. The instantaneous expansion self-recovery type upward floating device comprises free water, a free water sealing plate, solid calcium oxide, a heat transferring plate, a piston sealing ring, a piston, a plug, an oil bag, hydraulic oil, a limiting block sealing ring, a limiting block magnet shim, a limiting block magnet, a limiting block, a piston magnet, a piston magnet shim, ammonium nitrate, a heat transferring plate sealing ring, a hydraulic cylinder, a free water sealing plate sealing ring, a coupling, a linear motor and a conical sealing cover. According to the device, the ammonium nitrate is heated and reacts to produce a gas; gas pressure quickly increases to push the piston to move for compressing the hydraulic oil; the oil bag is squeezed through the hydraulic oil to make a water displacement volume become large; the purpose that the buoyant force of a buoyant force regulating device quickly becomes large is achieved. The device has the characteristics of being simple in structure and quick in response. By using the instantaneous expansion self-recovery type upward floating device, the problem of providing a power source for a conventional electrically driven buoyant force regulating device of a deep-sea sampler in extreme conditions that the electric quantity of a storage battery is exhausted and the energy source supply is short is mainly solved.
Description
technical field [0001] The invention relates to a buoyancy regulating device, in particular to a floating device utilizing an explosive full-sea depth self-sampling device. Background technique [0002] At present, the commonly used pressure adjustment device for marine submersibles usually adopts the method of increasing the volume of the oil bag to increase the buoyancy, that is, the hydraulic oil is compressed through the motor reducer-ball screw-piston, and then the hydraulic oil is used to squeeze the oil bag, so that the oil The drainage volume of the bladder becomes larger, so as to control the buoyancy of the marine submersible. In general, this method can more accurately adjust the buoyancy of the marine submersible. However, due to the unpredictability of the underwater environment, the marine submersible may be stuck by obstacles during the ascent process, resulting in an extreme situation where the motor is idling and the battery power is exhausted. Therefore, ...
