[0003] Existing hydropower generation equipment generally has a rated rotation speed. When the rotation speed of the existing hydropower generation equipment is higher than the rated speed for a long time, the heat generated by the friction of the existing hydropower generation equipment will be far greater than the heat dissipated by the cooling mechanism. , causing the existing hydroelectric power generation equipment to be damaged due to excessive temperature. Not only that, the water in the river will carry a large number of foreign objects, which will enter the interior of the existing hydroelectric power generation equipment with the water flow, causing damage to the turbine or blockage of the pipeline

The invention relates to hydraulic power generation equipment with overload protection and foreign matter removing functions. The equipment comprises a water inlet pipe, a rotating box, a water turbine, a drainage pipe, a rotating shaft, a power generation mechanism, an adjusting mechanism and a shaking mechanism; the power generation mechanism comprises an outer shell, a coil and multiple magnets; the adjusting mechanism comprises an extension unit and a rotating unit; the shaking mechanism comprises a fourth gear, a third gear, a dowel pin and a moving unit; and the moving unit comprises a swing rod, a moving rod, a moving block and a filter screen. In the hydraulic power generation equipment with the overload protection and foreign matter removing functions, the adjusting mechanism canadjust the water inlet quantity of the water inlet pipe according to the rotating speed of the water turbine to prevent burnout of the hydraulic power generation equipment due to the rotating speed higher than the rated rotating speed for a long time; and moreover, through the shaking mechanism, the hydraulic power generation equipment can remove foreign matters accumulated on the filter screen toprevent the foreign matters from entering the hydraulic power generation equipment along with water currents to prevent damage of the water turbine and blockage of the pipe.
Description
technical field [0001] The invention relates to the field of water conservancy power generation equipment, in particular to a water conservancy power generation device with functions of overload protection and foreign matter removal. Background technique [0002] The function of hydroelectric power generation equipment is to transfer water with potential energy from high places such as rivers and lakes to low places, and convert it into mechanical energy of the water turbine through the water turbine, and the water turbine drives the generator to generate electricity, converting the mechanical energy into electrical energy. [0003] Existing hydropower generation equipment generally has a rated rotation speed. When the rotation speed of the existing hydropower generation equipment is higher than the rated speed for a long time, the heat generated by the friction of the existing hydropower generation equipment will be far greater than the heat dissipated by the cooling mechani...
