Motor stator non-removable underwater engineering conveying belt

Abstract

The invention discloses a motor stator non-removable underwater engineering conveying belt. The underwater engineering conveying belt can dive to depth of thousands of meters and is free of water seepage drainage at regular intervals and free of maintenance, and is composed of an underwater conveying belt structure and a special underwater dragging motor, wherein 1, a transmission mode of underwater dragging motor (11) horizontal operation vertically driven by the underwater dragging motor is performed, a vertical bevel gear and an end transverse bevel gear are transmitted in a reversing modeof mutual and vertical tooth connection through a gear box; 2, the structure of the underwater dragging motor is performed, a stator (1) and a rotor (2) are surrounded by a metal sealing isolation shielding cavity in a three-dimensional form, and the bottom of the metal sealing isolation shielding cavity is provided with a rotating shaft (6) which can penetrate a motor shaft seal (7) downwards andan oil filling nozzle (D) which is connected or directly arranged through a pipe; and all the splicing gaps involved in the metal sealing isolation shielding cavity are realized through connection ofa non-removable welding process. According to the motor stator non-removable underwater engineering conveying belt, the accumulated time duration of underwater one-step working and idle operation canbe generally 15 years or above, or even 50 years or above.

Description

technical field [0001] The invention relates to an underwater mining engineering conveyor belt capable of deep diving and maintenance-free. 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...

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 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, 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.
