Sinking pump for exploiting combustible ice through decompression method

Abstract

The invention discloses a sinking pump for exploiting combustible ice through a decompression method. The sinking pump comprises a pump body, a pump cavity and a driving cavity are arranged at the upper portion and the lower portion of the pump body, a double-shaft extension motor is arranged in the driving cavity, a plurality of sliding blocks are installed in the circumferential direction of theside face of the double-shaft extension motor, the sliding blocks are in sliding connection with guide rods in a matched manner, and the inner sides of the guide rods are further provided with stretchable rods used for pushing the sliding blocks; and a rotating shaft is installed in the pump cavity, an impeller is installed on the rotating shaft in the pump cavity, and a plurality of stirring blades are installed on the side face of the fixing sleeve and at the upper end of the rotating shaft; and a drilling rod is installed at the lower end of the pump body, a second connecting base is installed at the upper end of the drilling rod, a first connecting base is installed at the lower end of the rotating shaft, a first connecting head is installed at an output shaft on the upper side of thedouble-shaft extension motor, and a second base is installed on an output shaft of the lower side of the double-shaft extension motor. The sinking pump is novel in structure, selection and control work is facilitated, the processing quantity within unit time is improved, and efficiency is improved.

Description

technical field [0001] The invention relates to the field of water pumps, in particular to a submersible pump used for mining combustible ice by a decompression method. Background technique [0002] Natural Gas Hydrate (Natural Gas Hydrate / Gas Hydrate), chemical formula CH4 xH2O. Flammable ice is an ice-like crystalline substance distributed in deep-sea sediments or permafrost in land areas, formed by natural gas and water under high-pressure and low-temperature conditions. Because it looks like ice and can burn when exposed to fire, it is also called "combustible ice" or "solid gas" and "air ice". It is actually a solid block. Natural gas hydrates are widely distributed in continental permafrost, slopes of islands, uplifts of active and passive continental margins, polar continental shelves, and deep-water environments in oceans and some inland lakes. [0003] The existing submersible pumps used for mining combustible ice are inconvenient to select and control, have low s...
