Description
Technical Field
The utility model relates to a new forms of energy electricity generation technical field, concretely relates to multi freedom wave energy power generation facility.
Background
Nowadays, the traditional fossil energy is increasingly exhausted, people increasingly recognize that the development and utilization of renewable energy is an important means for solving the current energy crisis. Renewable energy sources include solar energy, wind energy, biomass energy, wave energy, tidal energy, ocean thermal energy, geothermal energy, and the like. The earth's surface has 70% of its area in the ocean, which contains huge energy. In the sea, "there are three storms without wind, and there are taurows of storms with wind. "therefore, the ocean contains huge wave energy resources. China has the ocean area of 299.7 ten thousand square kilometers, and the ocean energy development and construction conditions are good. The coastline length of China is 1.8 kilometers, the coastline is ranked fourth in the world, the ocean area governed by China is ranked fifth in the world, ocean resources are abundant, and the coastline ranks top in the world. At present, the importance of wave energy development is recognized in china, the united states, european regions and india on a global scale, and organizations such as institute of science and university are actively committed to research and design various wave energy power generation devices, and incorporate wave energy into strategic energy structures of the country.

The overall size of the oscillating float type wave energy power generation device is not large, the device is not limited to installation and fixed positions and can be put into deep water areas without being limited to the coast, and the power generation form is also known as the wave energy power generation form which brings economic benefits to the greatest extent. The oscillating floats have six degrees of freedom in the ocean due to the irregular random motion characteristics of waves, namely pitch, surge, roll, sway, heave and yaw. The floating body is an energy capturing device for the first-stage energy conversion of direct contact with waves, so that the floating body structure with more degrees of freedom can capture the wave energy to a greater extent.

The floater structure integrates three degrees of freedom of rolling, heaving and pitching on the whole, so that the multi-degree-of-freedom wave energy power generation device realizes the function of capturing and converting wave energy with multiple degrees of freedom.
As shown in fig. 4-6, the transmission mechanism 3 is an axisymmetric structure, and includes a cover plate 3-1, a push rod 3-2, a sleeve 3-5, a screw rod slider 3-3, a ball screw 3-4, a one-way bearing 3-6, a bevel pinion 3-7, a housing 3-8, a bevel pinion 3-9 and a pin coupling part 3-10,
after one end of the push rod 3-2 is provided with the screw rod sliding block 3-3, the other end is inserted into the sleeve 3-5 until the end part extends out of the through hole at the other end of the sleeve 3-5 and is connected with the cross support plate 4-1, after the push rod 3-2 is arranged, the push rod 3-2 can slide in the sleeve 3-5 through the screw rod sliding block 3-3, one end of the ball screw 3-4 penetrates through the center of the screw rod sliding block 3-3 until the end part extends into the push rod 3-2, the sleeve 3-5 and the shell 3-8 are arranged to form a T-shaped structure, a rectangular groove space is formed inside the shell 3-8, a pair of generators 9 are respectively arranged at two ends of the rectangular groove space, the number of the small bevel gears 3-7 corresponds to that of the generators 9 one by one, the small bevel gears are respectively installed on the connecting shafts of the two generators 9 one by one, the centers of the large bevel gears 3-9 are installed at the other ends of the ball screws 3-4 and are meshed with the two small bevel gears 3-7 at the same time, the one-way bearings 3-6 are installed between the small bevel gears 3-7 and the connecting shafts of the generators 9, the cover plate 3-1 is detachably installed on the shell 3-8 so as to seal the rectangular groove space, and the pin connecting parts 3-10 are formed on the outer end face of the cover plate 3-1 and are connected with the fixing mechanism. As shown in the cross section of fig. 5, when waves push the float to rotate counterclockwise, the push rods 3-2 of the four transmission mechanisms 3 on the left of the float cross support plate 4-1 contract under the action of the float, reciprocating linear motion of the push rods 3-2 is converted into rotary motion of the bevel pinions 3-9 through the ball screws 3-4 in the transmission mechanisms 3, then the bevel pinions 3-7 are driven to rotate by the bevel pinions 3-9, because the one-way bearings 3-6 are additionally arranged between the generator 9 and the bevel pinions 3-7, the bevel pinions 3-7 on one side always idle and do not transmit torque, and the bevel pinions 3-7 on the other side are locked by the one-way bearings 3-6 to drive the generator 9 to rotate for generating electricity.
