Dragging motor of waterproof sealing using oil liquid jacking and capable of deep diving and free of maintenance and applied to simple underwater device

Abstract

The invention discloses a dragging motor of waterproof sealing using oil liquid jacking and capable of deep diving and free of maintenance and applied to a simple underwater device. A rotor (2) is atleast surrounded by a wide-type metal sealing isolated shield (5) in a three-dimensional form, and a motor shaft seal (7) capable of downwardly penetrating a rotary shaft (6) is arranged at the bottomof the wide-type metal sealing isolated shield (5); an oil liquid S fills the wide-type metal sealing isolated shield (5); the connection of all splicing gaps for the wide-type metal sealing isolatedshield (5) is realized through a non-removable welding technology; the dragging motor is applied to other underwater devices in the vertical direction underwater through positioning of a mounting plate frame (W) connected with the motor; and the oil liquid is a light oil liquid S of a low freezing point less than 0 DEG C. The accumulated duration of one-time operation and idleness of the draggingmotor 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 a dragging motor for a simple underwater appliance which uses oil to support a waterproof seal and is capable of deep diving without maintenance. 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, th...

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.
