Embodiment Construction
[0020] The present invention will be further described below in conjunction with accompanying drawing.
[0021] refer to Figure 1-6 , the present invention is used for the submerged microturbine electric generator of hydrothermal power generation, comprises the impeller shaft 5 of coaxial line device from inside to outside, stepped cylindrical clapboard cover body 4, heat insulation cover 2 and outer cavity body 3. One end of the outer cavity 3 is fixed with a steam inlet end cover 1, and the other end is fixed with a steam outlet end cover 12. The outer cavity, the inlet end cover, and the steam outlet end cover are provided for the underwater micro turbine generator. A working space is isolated from the outside world, and the heat insulation sleeve can prevent or weaken the high-temperature working fluid flowing through the working space from being cooled by the cold sea water outside, thereby reducing the power generation capacity of the turbo-generator.

The invention discloses an underwater micro steam-turbine generator used for submarine hydrothermal solution power generation. The underwater micro steam-turbine generator mainly comprises an impeller shaft, a partition board sleeve body, a heat insulation sleeve and an outer cavity, which are coaxially arranged from inside to outside, and further comprises a steam inlet end cover, a steam outlet end cover, a plurality of partition plates, a plurality of sleeves and a power generator, wherein a steam inlet is formed in the steam inlet end cover; a steam inlet through hole and a steam outlet through hole are formed in the partition board sleeve body; a steam outlet is formed in the steam outlet end cover; the steam inlet, the steam inlet through hole, blades on a partition board and a sleeve, the steam outlet through hole, a gap between the heat insulation sleeve and a small-diameter cylinder and the steam outlet form a steam flow channel. According to the device, a steam turbine and a power generator are integrated into a cavity, so that the underwater micro steam-turbine generator is small in size and great in power generation amount. The underwater micro steam-turbine generator is simple in connection, convenient in use, can be used by only needing to connect a steam inlet pipeline, a steam outlet pipeline and a cable for outputting electric energy, and is beneficial for integration and arrangement of the whole power generator. During design, the whole power generator can regulate power generation amount by flexibly changing opening-closing degree of the steam inlet according to the needs, and is high in universality.
Description
technical field [0001] The invention relates to a power generation device, in particular to an underwater micro steam turbine generator device used for hydrothermal power generation on the seabed, and belongs to the field of utilization and development of hydrothermal resources on the seabed. Background technique [0002] Modern seafloor hydrothermal activity is a process of energy and material exchange between the lithosphere and the ocean that generally develops on the boundaries of active plates in the ocean and in the volcanic centers inside the plates. Its prominent appearance is the flow of high-temperature hydrothermal fluids from the sea floor. This marine geological phenomenon has caused special seabed landform features and overlying water body anomalies, and due to the existence of high-temperature heat sources, modern seabed hydrothermal active areas usually have large seabed heat flow anomalies. [0003] The earth is continuously transferring heat from the insid...
