Floating impeller serial hydraulic turbine

Abstract

The invention relates to a floating impeller serial hydraulic turbine which is characterized by comprising a floating body (1), a variable-speed gear box (2), a generator (3), a bevel gear box (4), a transmission shaft (5) and an impeller group (6). The impeller group (6) comprises a plurality of shafts (61) which are connected with each other in series, wherein each shaft (61) is provided with aplurality of impellers (62); one end of the transmission shaft (5) is connected with the shafts (61) which are arranged on one end of the impeller group (6) through a universal coupling, and the other end is connected with the input shaft (41) of the bevel gear box (4); the input shaft (41) of the bevel gear box (4) is connected with a vertical output shaft (42) through a bevel gear (7a); the vertical output shaft (42) is connected with the low-speed shaft of the variable-speed gear box (2) through the bevel gear (7b); and the high-speed shaft (22) of the variable-speed gear box (2) is connected with the input shaft of a motor (3). The invention has the advantages of high reliability, long service life and wide application range.

Description

technical field [0001] The invention relates to a water turbine, especially a floating impeller series water turbine that can be installed on the sea water surface of rivers and lakes with small drop for power generation or air compression, and belongs to ocean current energy, tidal current energy and river and river energy field of utilization technology. Background technique [0002] At present, the existing hydroelectric power station is built on the barrage, which collects and raises the water level of the river, and uses the water level drop during the discharge to drive the blade turbine of the power station to rotate, and then drives the generator to generate electricity. This kind of fixed power station has the advantage of large power generation, but this method still has huge investment, long construction period, and has a certain impact on shipping and ecological environment, and will also generate a large number of immigrants, thus limiting the development of hyd...

AI Technical Summary

Problems solved by technology

But it also has the following problems: 1, the blade water turbine is a single set of blade structure, so that the power of the device is smaller thereupon, and cannot satisfy people's needs

2. The diameter of the single-set blade structure is large, so it cannot be used in places where the water flow is shallow, and the scope of use is small

3. There is a problem of inconvenient maintenance and management
