specific Embodiment approach 1

[0018] Specific implementation mode one: combine Figure 1-Figure 4 Illustrates that a river bed dam-free hydroelectric power generation system in this embodiment includes a water turbine, a guide body 17, a guide plate 18, two Π-shaped frames 1, two sets of bearing platforms 6, two sets of power generation platforms 7, two sets of generators 20. Two sets of speed increasing gear sets 21 and two sets of lifting mechanisms;

[0019] The two Π-shaped frames are reinforced concrete frames, and the two Π-shaped frames 1 are arranged facing each other. A set of bearing platforms 6, a set of power generation platforms 7, a set of generators 20, a set of The speed-increasing gear set 21 and a set of lifting mechanism; the bearing platform 6 is installed between the two columns 1-2 of the Π-shaped frame, and the water turbine includes a rotating shaft 4 and a plurality of bending blades 5, and each bending blade 5 is two sections type bending blade, the rotating shaft 4 is arranged h...

specific Embodiment approach 2

[0021] Specific implementation mode two: combination figure 1 and figure 2 To illustrate, the bearing bush 9 in this embodiment is an elastic metal-plastic bearing bush. This embodiment cancels the engine oil lubrication mechanism, avoiding the phenomenon of engine oil polluting the water body, and the allowable pressure of the elastic metal plastic bearing bush is controlled at 20Mpa / cm 2 Below, the allowable line speed is controlled below 20m / s, the maximum allowable PV value is controlled below 80Mpa·m / s, and the dry dynamic friction coefficient is 0.12-0.20. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0022] Specific implementation mode three: combination image 3 Note that the power generation system in this embodiment further includes two filter screens 22 , and the bottom of the two sets of bearing platforms 6 are respectively installed with filter screens 22 . Such setting prevents impurities from entering the bearing pad and affecting the operation of the rotating shaft. Others are the same as in the first or second embodiment.

Abstract

The invention discloses a riverbed non-dam type hydroelectric generation system, and relates to a hydroelectric generation system. The riverbed non-dam type hydroelectric generation system is used for solving the problems that an existing traditional hydropower station is high in manufacturing cost and large in work amount, a floating boat-type non-dam hydropower station can only be implemented in great rivers, the utilization rate of hydropower resources is relatively limited, and a tidal power station is high in construction cost, and cannot be utilized in a large-scale mode. The riverbed non-dam type hydroelectric generation system comprises a water turbine, a flow guiding body, a flow guiding plate, two right-angled-n-shaped frames, two bearing platforms, two power generation platforms, two generators, two increasing gear trains and two lifting mechanisms, wherein one bearing platform, one power generation platform, one generator, one increasing gear train and one lifting mechanism are installed on each right-angled-n-shaped frame, the water turbine comprises a rotary shaft and a plurality of bent blades, each power generation platform which is connected with the corresponding bearing platform is installed above the corresponding bearing platform, each generator is installed on the corresponding power generation platform, motors are connected with worm wheels respectively, and threaded rods are connected with the power generation platforms respectively. The riverbed non-dam type hydroelectric generation system is used for carrying out hydroelectric generation.

Description

technical field [0001] The invention relates to a hydropower generation system, in particular to a river bed dam-free hydropower generation system, which belongs to the field of hydropower generation. Background technique [0002] Traditional hydropower stations need to build dams to store water, divert canals, requisition forests, land requisitions, emigrate, block fish passages, change the natural ecology and climate environment, etc. The amount of engineering is huge, the investment is huge, and soil erosion and geological disasters are prone to occur; Power generation is intermittent and unstable, which affects grid stability and power quality; photovoltaic power generation occupies a large area of ​​land, high cost, low energy efficiency, frequent grid dispatching, immature technology, and large national subsidy investment; floating ship type hydropower without dams Areas that require a water depth of more than 10 meters and a flow velocity of ≥1 m / s can only be impleme...
