Abstract
The invention relates to the technical field of wind power generating equipment, in particular to a sliding rod type wind turbine blade adjusting mechanism. An existing mechanism in the prior gear art has the problems that the torque is large, the reliability is poor, and the blade angle is difficult to control. The sliding rod type wind turbine blade adjusting mechanism comprises a driving motor fixing disk, an adjusting disk, a blade shaft, adjusting disk connecting joints, an adjusting disk connecting shaft, connectors, connector connecting pins, blade shaft connecting pins and a sliding rod mechanism. The adjusting disk connecting joints are evenly arranged on the outer lateral side of the adjusting disk, the connectors are connected with the adjusting disk connecting joints through the connector connecting pins, and connecting rods are in threaded connection to the connectors; sliding blocks are inserted into the connecting rods and connected with the ends of the blade shaft through the blade shaft connecting pins; and the adjusting disk is connected with a power outputting shaft of a driving motor. By means of changing the structure of the blade adjusting mechanism, a transmitting mode is changed, and the transmitting stability and accuracy are improved.
Description
Technical field
The present invention relates to technical field of wind power generating equipment, specifically a kind of sliding rod type wind wheel blade controlling mechanism.
Background technique
Blade of wind-driven generator controlling mechanism is by being connected with power unit, and drive main drive gear to rotate, the transmission through driving mechanism carrys out adjusting vane Windward angle.
At present, blade of wind-driven generator or be that tilt fixing is installed or is the angle independent regulation of each blade.Blade angle independent regulation poor synchronization.
In addition, disclosed in the patent of invention of application for a patent for invention numbers 201410561011.7 and utility model patent ZL201420608931.5, a kind of gear structure of single frame posture impeller is also undesirable in blade angle control.Cause overall operation and unit cost of electricity-generating still undesirable.
Summary of the invention
The object of this invention is to provide a kind of sliding rod type wind wheel blade controlling mechanism, overcome deficiency of the prior art, change blade adjustments mode, blade adjustments is realized synchronous, reduce regular maintenance cost, make wind speed that scope can be utilized significantly broadening, improve generating efficiency.
Technological scheme of the present invention comprises the power unit that major axis horizontal is arranged; Also comprise drive motor fixed tray, adjustment disk, sharf, adjustment disk connection joint, adjustment disk coupling shaft, connecting head, connecting head connecting pin, sharf connecting pin, sliding bar mechanism;
Adjustment disk connects joint and is evenly arranged on adjustment disk outer side surface by adjustment disk coupling shaft, connecting head is connected joint by connecting head connecting pin and connects with adjustment disk, connecting rod is threaded connection on connecting head, slide block is inserted connecting rod and is connected by sharf connecting pin with sharf end, sharf is coordinated by the cylindrical sidewall of bearing with drive motor fixed tray, and spacing by end ring, adjustment disk is connected with the power take-off mechanism of power unit;
Further, the adjustable vane number of described propeller regulating mechanism is not limited to 12 shown in the drawings, does not affect the claim of this invention more than, the change that is less than this number or size.
The present invention has following beneficial effect: the present invention adopts slider-rocker mechanism, change blade adjustments mode, make adjustment of blade angle synchronous, and make the adjusting angle of blade easily control with stable, the use in low wind speed and high wind speed region can be met simultaneously, improve the wind energy utilization efficiency of blower fan, increase complete machine output power, thus reduce the cost of unit generated output; Solve that prior art Three-blade horizontal axis wind-driven generator output power is difficult to further increase, blower fan can utilize the problems such as wind speed range is narrower, adjustment of blade angle is asynchronous.The technology of the present invention feature structure is simple, and volume is little, lightweight, improves propeller regulating mechanism, rational in infrastructure, and loss is less, reduces rate of fault, facilitates regular maintenance, maintenance.
Below in conjunction with drawings and Examples, summary of the invention of the present invention is further described.
