Problems solved by technology
[0012] The purpose of the present invention is to provide a high-efficiency and energy-saving hydrodynamic device, which mainly solves the technical problem that the direction of the guide plate of the impeller cannot be actively adjusted when the existing water wheel device changes slightly in the direction of the water flow, and helps to improve the hydrodynamic force. The efficiency of the device, it can also adjust the direction of the guide plate to the position with the least water resistance when the water wheel is not needed

The present invention relates to technical field of energy conversion device, particularly a highly effective and energy saving hydrodynamic force apparatus, which includes blade wheel with driving shaft, wherein the blade wheel is circular and has a plurality of guide boards distributing around, characterized in that the guide board is connected to the blade wheel through a rotating shaft; the rotating shaft is controlled by a rotate motor and the driving shaft of the blade wheel is provided with a rotation speed detector; the signal output terminal of the rotation speed detector connects with the signal input terminal of a control unit; the signal output terminal of the control unit connects with the rotate motor. The technical problem of existing waterwheel apparatus that the direction of the guide board of the blade wheel cannot be adjusted on its own initiative when water stream direction changes slightly is solved through the invention, which is beneficial to improve efficiency of the hydrodynamic force apparatus; the invention can also adjust the direction of the guide board to the location where water resistance is minimum when waterwheel is not needed.
Description
technical field [0001] The invention relates to the technical field of energy conversion devices, in particular to a high-efficiency and energy-saving hydrodynamic device. Background technique [0002] China has been a country dominated by agriculture for a long time in history, and has made outstanding achievements in agricultural science and technology. In particular, many tools and equipment that are beneficial to agricultural production were invented, and the waterwheel is one of them. [0003] The main design principle of the waterwheel is to convert the potential energy of water into the kinetic energy of the waterwheel and water wheel, and use this kinetic energy to do work on mechanical equipment, so that it can carry out various industrial and agricultural production activities. Waterwheel equipment generally has one or more large impellers, which are impacted by the impact of water to rotate the axle and generate power. Because the diameter of the impeller of the...
