Underwater dragging motor of waterproof sealing using oil liquid jacking and capable of deep diving and free of maintenance for underwater diving projects or devices

Abstract

The invention discloses a dragging motor capable of deep diving and free of maintenance and achieving waterproof sealing using oil liquid jacking and a usage method thereof. In structure, a rotor (2)is at least surrounded by a wide-type metal sealing isolated shield (5) in a three-dimensional form, and a rotary shaft (6) capable of downwardly penetrating a motor shaft seal (7) and an oil chargingnozzle (D) for charging an oil liquid (S) are arranged at the bottom of a metal sealing isolated shielding cavity; and the connection of all splicing gaps for the metal sealing isolated shielding cavity is realized through a non-removable welding technology. The usage method is the driving conversion method of the dragging motor that must be used vertically, and is characterized in that an end vertical helical gear (8) which is connected to a vertical rotary shaft (6) and is vertically rotating and an end horizontal helical gear (9) which is connected to a horizontal roller (10) and is horizontally rotating are driven in a toothed connection conversion mode having mutually inclined angles. The accumulated duration of one-time operation and idleness of the dragging motor under the water generally can be more than 15 years, and may even reach 50 years or more.

Description

technical field [0001] The invention relates to a dragging motor, in particular to an underwater dragging motor which is waterproof and sealed by oil jacking and can be used for deep diving and maintenance-free diving projects or appliances. 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 mo...

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.
