Infinite dragging motor capable of deep diving

Abstract

The invention discloses an infinite dragging motor capable of deep diving. The structure of the motor filled with oil is characterized in that a rotor (2) or the rotor (2) and a stator (1) are at least surrounded by a narrow metal sealing isolation shield (4) or a wide metal sealing isolation shield (5) in a three-dimensional manner; a rotating shaft (6) capable of vertically and downwards penetrating through a motor shaft seal (7) is arranged at the bottom of the narrow metal sealing isolation shield (4) or the wide metal sealing isolation shield (5); the bottom of the narrow metal sealing isolation shield (4) or the wide metal sealing isolation shield (5) is provided with an oil filling nozzle (D) or a non-oil filling nozzle (D) which is connected through a pipe or directly arranged; the narrow metal sealing isolation shield (4) or the wide metal sealing isolation shield (5) is filled with oil (S); and all splicing gaps related to the narrow metal sealing isolation shield (4) or the wide metal sealing isolation shield (5) are connected through a non-detachable welding process. The one-time underwater service life is at least 10 years.

Description

technical field [0001] The invention relates to a drag motor capable of unlimited deep diving. Background technique [0002] At present, diving equipment of various specifications and models emerges in an endless stream. Among them, the most widely used and mature motor power equipment can only be used with various equipment that operates in the air, but cannot be equipped with various equipment that operates underwater. , the main reasons are: [0003] If the motor can work underwater, it is necessary to set up a waterproof sealing structure (for example: sealing rings of various specifications made of polymer flexible materials such as rubber or plastic as the main body) to resist external water bodies or high-pressure water bodies. For the motor Internal infiltration (once the water body comes into contact with the rotating motor rotor, the motor will be damaged), however, the setting of the waterproof sealing structure cannot resist the penetration of fluids including w...

Problems solved by technology

——If you put the fried dough sticks in a plastic bag, you will soon find that the oil on the fried dough sticks will seep out of the plastic bag, and people will find that the oil will leak into the plastic bag with naked eyes or hands The phenomenon on the outside is because oil as a liquid is a substance that is not easy to volatilize, and the leaked oil molecules are easy to remain in the form of liquid in the form of leakage outside the plastic bag; however, if the water is contained In a plastic bag, the water molecules leaked out of the plastic bag will immediately disappear in the form of evaporation from the naked eye.

[0006] Obviously: all the above-mentioned waterproof and sealing technical measures (mainly undertaken by adopting physical sealing elements) cannot achieve effective and permanent sealing effects from the molecular level; it is not difficult to imagine: any design using such effects The underwater driving motor required for underwater engineering must not continue to work or rest underwater permanently, and must be hoisted ashore regularly for disassembly and maintenance (not maintenance) with the main task of eliminating water seepage; If you want to use an underwater drag motor with tens of thousands of watts or even millions of watts, the troubles caused by "regular disassembly to eliminate water seepage maintenance" (not counting the influence of diving depth for the time being) during its use, It is even more unimaginable, so that people dare not think of using high-power underwater drag motors in permanent underwater projects or permanent underwater appliances.

[0007] For this reason: At present, non-underwater drag motors that can be used for diving equipment that can be used for a long period of time but have no limit to the depth of diving have not yet been proposed or come out.
