Problems solved by technology
[0002] The existing submersible technology uses water injection and drainage to the water storage tank to achieve submersion, ascent and balance. The disadvantage of this technology is that it takes a relatively long time and it is difficult to cope with unfamiliar ocean environments, especially in complex sea conditions. When encountering an emergency, the time left for the operator to deal with is short, and the risk of submersible navigation is relatively high

Embodiment Construction
[0004] 1. On the symmetrical sides of the bow, midship, and stern shells of the submersible, at the appropriate position between the midpoint of the horizontal axis and the lower horizontal axis at an angle of 25° to 50°, install six propellers directly driven by DC motors. The direct drive can It avoids unnecessary noise caused by indirect driving, takes up less space, and is also conducive to the modification of existing submersibles. Its design total thrust force is slightly greater than the gravity of the submersible under the condition of full load and deep drop.
[0005] 2. It is advisable for the pusher to be embedded and installed to prevent collision and entanglement of sundries, or it can be equipped with a protective cover or a movable cover door.
[0006] 3. Each thruster is controlled by the depth control processor. The depth gauge and balancer of the submersible provide reference signals for the control processor. After the submersible is started, the depth contr...

The invention relates to a deep falling prevention method for a submersible. The deep falling prevention method provided by the invention is mainly used for solving the problem that the submersible is subjected to deep falling due to displacement cliff encountering during navigation. According to the method, impellers which are directly driven by direct-current motors are mounted at symmetric two sides of a shell of the submersible of a bow section, symmetric two sides of a shell of the submersible of a midship section, symmetric two sides of a shell of the submersible of a stern section, the middle point of a horizontal axis and appropriate positions, which are located below the horizontal axis and form included angles, of which each is 25-50 degrees, with the horizontal axis, each impeller is controlled by a deep falling control processor, an alarm is given when preset alarm is triggered, the impellers are started up when preset processing is triggered, the size of an impelling force of each impeller is adjusted and controlled so as to maintain the depth and balance for the submersible, the impellers stop working until operating personnel complete processing, and a controller returns to a standby state. The method is applicable to various submersibles.
Description
Technical field: [0001] The anti-falling deep method of submersible is mainly for solving the method invention that submersible encounters " cliff " and falls deep when sailing. Background technique: [0002] The existing submersible technology uses water injection and drainage to the water storage tank to achieve submersion, ascent and balance. The disadvantage of this technology is that it takes a relatively long time and it is difficult to cope with unfamiliar ocean environments, especially in complex sea conditions. When encountering an emergency, the time left for the operator to deal with it is short, and the risk of the submersible's navigation is relatively high. Invention content: [0003] Six or four thrusters are installed on the submersible. When the submersible encounters unexpected situations such as falling deep, the thrusters will start quickly, and the thrusters will work to maintain the depth and balance of the submersible. An extra level of security is ...
