Abstract
The utility model discloses a river bottom fall type power device which comprises a fixed seat. A connection rod is arranged on the fixed seat. An outer shell is arranged on the connection rod. A water inlet and a water outlet are formed in the outer shell. An upper bearing seat and a lower bearing seat are arranged on the outer shell. A vane connection shaft is arranged between the upper bearing seat and the lower bearing seat. A power output shaft is arranged on the vane connection shaft. At least six rotation vanes are arranged on the vane connection shaft. Concave grooves are formed in the rotation vanes. The outer shell is a hollow cylindrical body. The cross section of the water inlet is L-shaped. The outlet is arc-face-shaped. The river bottom fall type power device has the advantages of being small in size, simple in structure, little in investment, little in water flow and capable of outputting power to generate under a low water level.
Description
Technical field
The utility model relates to hydroelectric installation, relates in particular to a kind of river bed falling difference type power plant.
Background technique
At present, existing hydroelectric installation is to utilize water flow big mostly, the place that water level is high is carried out barrage and is built a dam, drop impulse force by current rotates the power plant blade that is positioned at height of water below and carries out power output generating, the most volume of these power plant is big, complex structure is invested more.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provides a kind of volume little, and is simple in structure, invest less, and little in water flow, the also river bed falling difference type power plant that generate electricity of exportable power under the lower environment of water level.
The purpose of this utility model is achieved in that it comprises fixed base, described fixed base is provided with connecting rod, connecting rod is provided with shell, shell is provided with water intake and drain opening, shell is provided with upper bearing bracket and step, be provided with the blade coupling shaft between upper bearing bracket and the step, be provided with six rotor blades on the blade coupling shaft at least, be connected with pto on the described blade coupling shaft.
Described rotor blade is provided with hollow slot.
Described shell is hollow cylinder.
Described water intake cross section is L shaped; Described drain opening is arc surfaced.
Because adopt technique scheme, the river bed falling difference type power plant that the utility model provides have following advantage: volume is little, and is simple in structure, invest lessly, and without retaining, take up an area of less, under the lower environment of water level also exportable power generate electricity.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model when being located at the river bed face.
Drain opening in the drawings, 1, fixed base, 2, connecting rod, 3, shell, 4, water intake, 5,, 6, upper bearing bracket, 7, step, 8, the blade coupling shaft, 9, rotor blade, 10, hollow slot, 11, pto, 12, He Ba, 13, drop water, 14, river bed water, 15, the river bed face.
Embodiment
As shown in Figure 1, the river bed falling difference type power plant that the utility model provides comprise fixed base 1, described fixed base 1 is provided with connecting rod 2, connecting rod 2 is provided with shell 3, shell 3 is provided with water intake 4 and drain opening 5, shell 3 is provided with upper bearing bracket 6 and step 7, be provided with blade coupling shaft 8 between upper bearing bracket 6 and the step 7, at least be provided with six rotor blades 9 on the blade coupling shaft 8, be connected with pto 11 on the described blade coupling shaft 8, described rotor blade 9 is provided with hollow slot 10, and described shell 3 is hollow cylinder, and described water intake 4 cross sections are L shaped; Described drain opening 5 is arc surfaced.
During concrete the use, pto 11 of the present utility model and the generator that needs generating are connected, then the utility model is placed on drop water 13 belows that dam, river 12 has the height of water, make shell be higher than 14 in river bed water, fixed base 1 is embedded in the river bed face 15, and allow water intake 4 towards the current that fall, current fall to flow to and flow away from drain opening 5 after water intake 4 drives rotor blade 9 rotations again, because rotor blade 9 is provided with hollow slot 10, so rotor blade 9 is subjected to the current dynamics bigger, rotational velocity is also very fast, the rotor blade 9 that rotates drives blade coupling shaft 8 and rotates, blade coupling shaft 8 drives pto 11 again and rotates, and last pto 11 is transported to generator to power and carries out generating work.
