Underwater engineering conveying belt

Abstract

The invention discloses an underwater engineering conveying belt and particularly relates to a maintenance-free (in terms of the lifetime of the conveying belt) underwater conveying belt capable of diving deeply (the water depth can exceed one thousand meters). The conveying belt is composed of an underwater conveying belt structure and a special underwater dragging motor. Firstly, the underwaterdragging motor vertically drives an underwater conveying belt (11) to horizontally operate, and driving is achieved in a gearbox mutual perpendicular toothing connection reversing mode; and secondly,according to the structure of the underwater dragging motor, at least a rotor (2) is wrapped with a metal seal isolating shielding cavity in a vertical mode, and in addition, a rotary shaft (6) capable of penetrating through a motor shaft seal (7) downwards and a filling nozzle (D) arranged directly or through a pipe coupling are arranged at the bottom of the metal seal isolating shielding cavity.All spicing gaps related to the metal seal isolating shielding cavity are connected through a detachable welding technology. According to the underwater engineering conveying belt, the aggregated duration for one-time underwater working and idling of the conveying belt can generally reach up to more than 15 years or even reach up to 50 years or more.

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 with different specifications and models emerges endlessly. Among them, the most widely used and mature electric power equipment can only be used with various equipment that runs in the air, but cannot be used with various devices that run underwater. The main reasons are: [0003] If the motor can work underwater, it is necessary to set up a waterproof sealing structure (for example: various specifications of sealing rings made of flexible polymer materials such as rubber or plastic as the main body) to resist external water or high-pressure water to the motor Internal infiltration (Once the water body contacts the rotating motor rotor, it will cause damage to the motor). However, the setting of the waterproof sealing structure cannot resist the molecular weight of the fluid including...

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.
