Background

The hydroelectric generators are classified into different types according to specific conditions such as conditions, positions, and scales of installation sites, but basically, the hydroelectric generators rotate a water turbine by using potential energy falling from a high place to a low place, and generate electricity by using the rotational force as a driving source of the generator. When the water turbine is used, the water turbine is driven to rotate through water flow, and then the generator is driven to generate electricity. The requirement on geological landform is high in the using process, the construction period of the project is long, and the construction cost of the project is extremely high. Chinese patent application 201210579086.9 discloses a 'submersible running water turbine power station' invention patent, which adopts a turbine runner type blade design to increase the area of a stressed blade, thereby achieving the purpose of increasing the mechanical energy conversion rate. The turbine runner type blade has the advantages that the maximum stress area is the sum of the blade areas, mechanical energy cannot be increased to a greater extent, the resistance of water flow is increased due to the fact that the blade area of the generator is too large, the speed of the water flow passing through the generator is reduced, meanwhile, the generator is generally limited by the height difference of the water flow, the problem of sand accumulation is easy to occur, the large amount of sand accumulation is easy to generate after the turbine runner type blade is used for a long time, the blades of a power generation device are abraded greatly, and power generation efficiency is influenced.

The utility model has the following concrete scheme: a self-flowing water power generation device is provided with a floating body, at least one rotating shaft is downwards arranged in the middle of the floating body, a plurality of water flow blade groups are arranged on the rotating shaft from top to bottom, the number of blades in each water flow blade group is kept consistent and is 3-6, the blades in each water flow blade group are uniformly distributed in an annular shape, and water flow impact surfaces on the blades are arranged in parallel with the rotating shaft; the upper end of each rotating shaft penetrates out of the floating body and is in transmission connection with a gear speed increaser, and the gear speed increaser is correspondingly in transmission connection with a generator.

Furthermore, in the present invention, the blade is an S-shaped blade.

Further, the utility model discloses in every epaxial rivers blade group quantity be 2, and the blade in two upper and lower rivers blade groups is the even arrangement of staggering each other from overlooking the direction or looking up the direction observation.

Furthermore, in the present invention, the gear speed increaser adopts a planetary gear speed increaser.

Furthermore, in the present invention, the floating body is any one of a metal hull, a wooden hull and a foam block.

The utility model discloses following beneficial effect has: firstly, the power generation related equipment of the utility model is designed on a floating body, and the floating body adopts various objects capable of floating on the water surface, thereby being suitable for various water bodies to generate power and having wide application range; secondly, a blade form that a plurality of water flow blade groups are arranged on a rotating shaft is adopted, and simultaneously, the blades in each blade group and the blades in other blade groups are arranged in a uniformly staggered manner when viewed from top or looking down, so that the design structure not only can effectively reduce the sand accumulation condition on the blades, but also can reduce the blade area which cannot be impacted by water flow as far as possible, and the effect of improving the rotating speed of the blades and the rotating shaft is obvious; thirdly, the utility model provides a rivers blading is from last to distributing down, and the requirement to the difference in height of rivers is not very urgent, as long as the rivers that flow can, adaptability is good, high to the utilization ratio of water resource.
