Description
Technical Field
The invention belongs to the technical field of underwater ice breaking, and particularly relates to an underwater ice breaking system of a high-speed revolving body.
Background
With the annual ablation of the arctic ice cover, the arctic channel development and resource exploration have bright prospects, and the demand for the research of a novel ice breaking method is increased day by day. At present, the mainstream ice breaking method mainly comprises an impact load ice breaking method, a mechanical ice breaking method, auxiliary ship motion type ice breaking and the like, and when a submarine needs to discharge water, an additional floating body (underwater submerged body) ice breaking method needs to be researched. Although the research on the ice breaking of the slow floating body in China is advanced at present, the design of experimental equipment for the ice breaking of the floating body of the high-speed underwater submerged body is very limited.
In the experiment of breaking ice of the high-speed underwater submerged body, two keys are that a driving device capable of providing sufficient pressure pneumatic pulse is quickly generated and the steel revolving body simulating the underwater submerged body quickly responds. In the known experimental technology of a device for generating pneumatic pulses, patent application No. 201910228272.X, "an air gun device for an underwater high-pressure gas ice breaking experiment," connects an electromagnetic piston with a sealing piston through a transmission connecting rod, and the sealing piston realizes device sealing through internal and external pressure difference between a high-pressure cylinder and the outside. From the processing perspective, two pistons of different materials are connected through the transmission light rod, and have higher requirements on processing precision, large processing difficulty and more complicated installation process. From the perspective of service life, because most of equipment is in a high-speed high-pressure working condition, the light bar is easy to deform or even bend in the frequent high-pressure use process, so that the service life of the device is reduced, and the transmission system needs to be improved. The patent application number is 201811169354.3 "an electromagnetic control's high pressure bubble source device under water" through an electromagnet control lever structure, produces pneumatic pulse under water under the spring action, does not consider the demand of repeated experiment, needs artifical recovery unit after the experiment at every turn, and the design of lever buckle makes a whole set of device structure complicated simultaneously, and stability is low, is unfavorable for carrying out a large amount of contrast experiments for a long time.
In the known revolving body response pneumatic pulse impact technology, a patent 'steel ball launching device' with the patent application number of 200420117070.7 uses two times of pneumatic pulses to launch a steel ball by shunting high-pressure gas, but the steel ball cannot be reset after being launched, a new steel ball needs to be manually placed in the steel ball launching device, the device places the steel ball through a ball inlet pipeline, the position of the device when the steel ball is placed in each experiment cannot be completely the same, in order to prevent a small ball from rolling, equipment must be always kept in a horizontal state, and great limitation is brought to the experiment environment; if the experiment requires to study the impact of steel balls with different sizes, additional gun heads with different inner diameters are required to be manufactured, and the impact test cannot be realized by directly replacing the small balls, so that the experiment efficiency is reduced, and the cost is increased.
The existing pneumatic pulse generating and responding device has the defects that:
(1) the two piston components are connected and processed through the light rod inconveniently and influence the service life of equipment.
(2) The structure is complicated, and the great majority needs lever mechanical structure or a plurality of solenoid valve simultaneous workings, and is high to the control accuracy demand.
(3) The repeatability is low, manual restoration equipment is needed, and the experimental efficiency is seriously influenced.
