Underwater dragging motor oil filling method capable of infinitely realizing deep diving and realizing waterproof sealing by jacking external force seepage water filled with oil

Abstract

The invention relates to an an underwater dragging motor oil filling method capable of infinitely realizing deep diving and realizing waterproof sealing by jacking external force seepage water filled with oil, namely a consolidation method for finally ensuring oil filling, which comprises the following steps of: placing a shaft seal (7) of the motor upwards, shaking the motor for a moment, pressurizing the whole machine through an oil filling nozzle (D), and filling oil (S); and when leaked oil liquid (S) is found at the shaft seal (7) of the inverted motor, determining that the filling consolidation program of filling the motor with the oil liquid (S) is completed. According to a related motor structure, at least a rotor (2) is surrounded by a metal sealing, isolating and shielding cavity in a three-dimensional mode, and the bottom of the metal sealing, isolating and shielding cavity is provided with a rotating shaft (6) capable of penetrating through a motor shaft seal (7) downwards and provided with or not provided with an oil filling nozzle (D); and all splicing gaps related to the metal sealing, isolating and shielding cavity are connected through a non-detachable welding process. The underwater one-time service life of the device can be at least 10 years or above.

Description

technical field [0001] The invention relates to a drag motor, in particular to a method for injecting oil into an underwater drag motor capable of diving infinitely deep and being filled with oil to support external force seepage and implement waterproof sealing. 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 contac...

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.
