Abstract
The utility model discloses a kind of cardan shaft hydraulic drive apparatus that is applicable to low water head generating, it is characterized in that, comprise major axis impeller, universal joint, generator and spring bearing, multiple described major axis impellers are together in series by described universal joint, join by described universal joint and described generator shaft, described major axis impeller is fixed on the ground by spring bearing again.The water kinetic energy that the utility model is applicable to the irregular landforms of small watershed very much transforms, little to the change of ortho states landforms, in hydroelectric resource development resource, farthest preserves the ecological environment, and device has good practicability, and cost is low, easy for installation, is applicable to applying.
Description
Technical field
The utility model relates to small watershed hydraulic power generation technology field, relates in particular to a kind of cardan shaft hydraulic drive apparatus that is applicable to low water head generating.
Background technique
The many mountains of south China are rainy, and development small power station has unique natural resource advantages.Small watershed in mountain generally has the features such as current are slow, head is not high, the water surface is not wide, waterpower is little.Traditional water filling that dams of building a dam, by artificial river closure mode, has improved head, has widened the water surface, has increased waterpower, thereby reaches reservoir impoundment power generation object.From the development situation of more than ten years in past, there are many problems in this water filling that dams of building a dam, and especially aspect small watershed ecological protection, agricultural irrigation, development mountain area sightseeing tour economic dispatch, impact significantly, is is urgently researched and solved.How, keeping or less change basin topography, protecting on ecological basis, by technological innovation, improving water power and utilize mode, is the research topic important when last.
Summary of the invention
For the current small watershed ecological problem of reservoir impoundment power generation mode of damming of building a dam, the utility model provides a kind of cardan shaft hydraulic drive apparatus that is applicable to low water head generating.
Technological scheme described in the utility model is:
A kind of cardan shaft hydraulic drive apparatus that is applicable to low water head generating, it is characterized in that, comprise major axis impeller, universal joint, generator and spring bearing, multiple described major axis impellers are together in series by described universal joint, join by described universal joint and described generator shaft, described major axis impeller is fixed on the ground by spring bearing again.
Further, described major axis impeller is made up of cylinder axis body, rectangular paddle, coupling shaft, and described rectangular paddle is embedded on described cylinder axis body equably by equal angles mode, and described cylinder axis body is connected on described spring bearing by connecting bushing.
Further, described universal joint comprises two Runner assemblies, connection part and connecting pin, and two described Runner assemblies are connected with described connection part by described connecting pin.
Working principle of the present utility model is as follows:
Major axis impeller is horizontal on active cross-section, flowing water directly impacts in the rectangular paddle of major axis impeller, makes major axis wheel rotation, because multiple major axis impellers are connected by universal joint, the water kinetic energy of everywhere can converge on generator shaft, finally drives generator generating.
The beneficial effects of the utility model are embodied in: the water kinetic energy that is applicable to very much the irregular landforms of small watershed transforms; little to the change of ortho states landforms, in hydroelectric resource development resource, farthest preserve the ecological environment; device has good practicability, cost is low, easy for installation, is applicable to applying.

Embodiment
Below in conjunction with embodiment, the utility model is described in further detail.
With reference to accompanying drawing 1 ~ 4, a kind of cardan shaft hydraulic drive apparatus that is applicable to low water head generating that the present embodiment adopts, it is characterized in that, comprise major axis impeller 1, universal joint 2, generator 3 and spring bearing 4, multiple described major axis impellers 1 are together in series by described universal joint 2, join by described universal joint 2 and described generator 3 axles, described major axis impeller 1 is fixed on the ground by spring bearing 4 again.
Described major axis impeller 1 is made up of cylinder axis body 11, rectangular paddle 12 and coupling shaft 13, described rectangular paddle 12 is embedded on described cylinder axis body 11 equably by equal angles mode, and described cylinder axis body 11 is socketed on described spring bearing 4 by coupling shaft 13.
Described universal joint comprises two Runner assemblies 21, connection part 22 and a connecting pin 23, and two described Runner assemblies 21 are connected with described connection part 22 by described connecting pin 23.
The working method of the present embodiment is as follows:
Major axis impeller 1 is horizontal on active cross-section, flowing water directly impacts in the rectangular paddle 12 of major axis impeller 1, and major axis impeller 1 is rotated, because multiple major axis impellers 1 are connected by universal joint 2, the water kinetic energy of everywhere can converge on generator 3 main shafts, finally drives generator 3 to generate electricity.
Content described in this specification embodiment is only enumerating of way of realization to the utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also and conceive the equivalent technologies means that can expect according to the utility model in those skilled in the art.
