Drawings
Fig. 1 is a structural diagram of a wave power generation device of the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1, the sea wave power generating apparatus of the present invention includes: the device comprises a floater 1, an input rope 2, a tidal range regulator 3, a driving chain 4, a gearbox 5, a tail chain 6, a balancing weight 7, a speed stabilizer 8, a generator 9 and a confluence voltage stabilizer 10.
The float 1 rises or falls with the waves. For example: a float 2 meters in diameter and 1.2 meters high, displacement is 3.77 cubic meters (buoyancy of 3.88 tons). The design is considered as 2.5 tons.
The input rope 2 is connected with the floater 1. The driving chain 4 is connected with the tail end of the input rope 2. The tail chain 6 connects the driving chain 4 and the counterweight 7. The tidal difference regulator 3 regulates the length of the input rope 2 according to the tidal level change. The rope is loosened when there is a tide and tightened when there is a tide. The weight 7 serves to tighten the input rope 2 during the rise cycle of the float 1. Work is not done during the rise of the float 1, and work is done during the fall of the float 1.
The gearbox 5 is in transmission connection with the driving chain 4 and is driven by the gravity of the descending period of the floater 1 to output corresponding rotating speed. The speed stabilizer 8 is used for adjusting the rotating speed output by the gearbox 5 and outputting the stable rotating speed. Specifically, the transmission case 5 includes: a drive sprocket engaged with the drive chain 4; a driving shaft which is connected with the driving sprocket through an overrunning clutch and is driven by the driving sprocket to rotate when the driving sprocket is driven by the gravity of the descending period of the floater 1; and the gear transmission set is used for transmitting and changing the rotating speed of the driving shaft and outputting the changed rotating speed.
The generator 9 is connected with the speed stabilizer 8 in a transmission way and generates electricity according to the stable rotating speed. The bus regulator 10 regulates and controls the voltage of the three-phase ac power output from the generator 9 within a predetermined voltage range. Finally, the bus regulator 10 is connected via a grid connection 11 for integration into the power grid.
The tidal range regulator 3, the gearbox 5, the speed stabilizer 8, the generator 9, the confluence voltage stabilizer 10 and the grid-connected device 11 are all arranged on a sea wave power generation platform 12.
The drive chain 4 moves repeatedly, driving the drive sprocket to move, the drive sprocket is connected to the drive shaft through a high torque overrunning clutch. When the floater 1 rises, the overrunning clutch slides, so that the driving shaft is not rotated, namely, power is not generated. The counterweight 7 only tensions the drive chain 4 and the input rope 2. When the float 1 descends, for example, the float with the weight of 2.5 tons consumes 50kg, even if the friction generated by the balance weight of 100 kg and other all transmission processes is overcome, 23KN of force (2.35TX 9.8-23 KN) drives the driving chain wheel to rotate. At this time, the overrunning clutch is locked, and the rotation of the driving chain wheel drives the driving shaft to rotate, so that the generator 9 generates electricity.
The above embodiments are provided only for the purpose of illustration, not for the limitation of the present invention, and those skilled in the relevant art can make various changes or modifications without departing from the spirit and scope of the present invention, therefore, all equivalent technical solutions should also belong to the scope of the present invention, and should be defined by the claims.
