Driving motor for diving apparatuses realizing waterproof sealing by jacking of oil, capable of deep diving and free of maintenance for water seepage elimination and using method thereof

Abstract

Disclosed are a driving motor for diving apparatuses realizing waterproof sealing by jacking of oil, capable of deep diving and free of maintenance for water seepage elimination and a using method thereof. In structure, at least a rotor (2) is surrounded by a narrow metal seal isolation shield (4) or a wide metal seal isolation shield (5) in a three-dimensional form, and all splicing gaps are connected by an irremovable welding process; and moreover, oil (s) is injected into the whole machine through an oil filling nozzle (D) at the bottom, and a detachable gap in any shape or a barrier layercomposed of a non-metallic macromolecule material cannot be formed in the structure in which a power cable penetrates the driving motor from the top or periphery. During use, the rotation in other directions must be driven on the basis of the positioning of the vertical direction, and the driving motor can be put into normal use only after the completion of a consolidation procedure for the injection of oil (s) into the driving motor is confirmed. The cumulative duration of underwater one-off work and idleness of the driving motor can generally be more than 15 years, or even 50 years or more.

Description

technical field [0001] The invention relates to a drag motor, in particular to a drag motor equipped with underwater power equipment and a use method thereof. 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 seali...

Problems solved by technology

[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 underwater permanently or be idle. Moreover, it must be hoisted ashore regularly for disassembly 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 unimaginable, so that people dare not think of using the existing technology drag motor of high-power underwater matching in permanent underwater engineering or permanent underwater appliances.

[0007] For this reason: at present, the drag motor that can be used for submersible equipment as described in the title of the present invention has not yet proposed or come out.
