Abstract

A convex type guide plate waterwheel energy increasing device with gradually dense holes is provided. The convex type guide plate waterwheel energy increasing device comprises fixed devices, a main diversion plate and auxiliary diversion plates, wherein an upwards convex arc structure is arranged on the top surface of the main diversion plate, gradually dense first through holes are formed in the main diversion plate from the middle to the two ends, the diameters of the first through holes are gradually increased, the auxiliary diversion plates are connected to the two sides of the main diversion plate, second through holes are formed in the auxiliary diversion plates, fixed devices are fixed to the two sides of the auxiliary diversion plates, and the fixed devices are used for fixing the main diversion plate and the auxiliary diversion plates to the riverbed. Through the convex type main diversion plate with the gradual dense holes with different heights, the device adapts to the condition that the distance between the waterwheel and the bottom of the riverbed is different along with the change of the phase angle, kinetic energy of low-velocity air at the bottom of the riverbed is conveyed to the impeller area of the waterwheel, the effective acceleration area in the river channel is large, the average velocity of water flow in the impeller area of the waterwheel is increased, and the output power of the unit is improved.
