Wind and wave double effect power generation device

The invention relates to a wind wave double-effect power generation device, in particular to a wind wave double-effect power generation device which can generate electricity by using wind and wave fluctuations.

A wave power generation device is a power generation device that generates wind power by wave fluctuations, and then drives a turbine to drive a generator to generate electricity. Referring to FIG. 11 , the known wave power generation device includes a base (40) and a turbine (50). And a generator (6), the bottom end of the base (40) forms an inlet and outlet (42), and an inlet and outlet (43) is formed on the near top side of the base (40), and the base (40) is internally Forming a passage (41) to communicate the inlet and outlet (42) and the inlet and outlet (43); the generator (6) is disposed on a top side of the base (40); the turbine (50) is disposed in the passage (41) The inside of the inlet and outlet (43) is located below, and an axial portion (51) of the turbine (50) is coupled to the output shaft of the generator (6).

The above-mentioned wave power generating device is disposed at the seaside, and the bottom end of the base (40) is not inserted into the seawater, so that the inlet and outlet (42) is located below the sea level, and enters the base from the inlet and outlet (42) (40) The internal seawater is airtight to the channel (41) at the end to form a water column piston. The water level in the channel (41) will rise and fall by the fluctuation of the waves, and the air above the channel (41) will flow. The turbine (50) is driven to rotate, which in turn drives the generator (6) to generate electricity.

The known wave power generation device uses the natural phenomenon of seawater to generate electricity, and does not generate electricity by means of combustion or nuclear energy. Therefore, in addition to providing electricity, it contributes to energy conservation and environmental protection. The power generation device needs to use the fluctuation of the ocean waves, so the inlet and outlet (42) need to be placed at a sea level where the waves are undulating, but if the position of the inlet and outlet (42) is set too high, when the waves fluctuate too much, the sea The plane is easily lower than the inlet and outlet (42), so that the seawater cannot seal the bottom end of the passage, but the power generation efficiency is reduced. Secondly, the known wave power generation device only uses the wave fluctuation to generate electricity, but the wind resources on the sea surface are not Therefore, if a wind power generation device can be effectively utilized to utilize the wind power on the sea surface, the power generation amount can be increased.

The main object of the present invention is to provide a wind and wave double-effect power generation device, which is designed to improve the airtight effect of the water column piston to improve power generation efficiency. Secondly, a wind power generation device is combined to increase the power generation amount.

In order to achieve the above, the wind wave double-effect power generation device of the present invention comprises:

a pedestal having a concave arcuate passage formed therein, one end of the arcuate passage extending to one side of the base to form an opening and upward opening, the other end of the arcuate passage extending to the top side of the pedestal Forming an inlet and outlet port at the inlet and outlet; a turbine assembly disposed above the base, the turbine assembly including a first turbine having an axial portion, a first deflector assembly, and a second shaft portion a first turbine is disposed at a top side of the base near the inlet and outlet, the first deflector is disposed outside the first turbine, and the second deflector is disposed at the turbine a second turbine outer side; and a power generating device including a generator and a transmission assembly, the shaft portion of the first turbine and the rotating shaft portion of the second turbine are coupled to the transmission assembly, and the transmission assembly is coupled to the generator .

The wind wave double effect power generation device of the invention has the following advantages:

1. The second turbine is directly driven by the wind on the sea surface and transmitted through the coupling of the coupling to drive the generator to generate electric power, thereby compounding a wind power generation device to provide another power generation source and increasing the power generation.

2. By setting the inlet and outlet of the opening upward, and the concave curved passage, the seawater flowing into the curved passage from the inlet and outlet can be left at the bottom of the inner side of the curved passage, and the curved passage of the end is airtight. The airtightness of the water column piston is not easily affected by wave fluctuations, thereby improving power generation efficiency.

The second object of the present invention is to further include the transmission assembly including two bevel gears and a coupling, wherein the two bevel gears are respectively disposed on the shaft center portion and the output shaft of the generator, and the two bevel gears are meshed with each other.

The arrangement of the one-way bearing means that the shaft portion of the second turbine can drive the shaft portion of the first turbine to rotate, but the shaft portion of the first turbine cannot rotate the shaft portion of the second turbine, so When the wind on the sea surface is insufficient to drive the second turbine to rotate, the first turbine can rotate independently, and the second turbine does not become the load of the first turbine to increase its moment of inertia, thereby avoiding reducing the power generation efficiency of the first turbine. .

Another object of the present invention is to further make the height of the bottom end of the top edge of the curved channel equal to or lower than the height of the inlet and outlet; the arc channel is internally spaced by a plurality of partitions, and the arc channel is divided into a plurality of independent Flow path.

Since the height of the bottom end of the top edge of the curved passage is equal to or lower than the height of the inlet and outlet, the fluctuation of the wave is excessively large, and the water surface inside the curved passage is lower than the top edge, so that the water column piston cannot be airtight. The case of the curved channel further increases the airtight effect to improve the power generation efficiency; and the plurality of partitions divide the curved passage into a plurality of independent flow passages, so that the independent flow passages can independently generate electricity, and The arc channel is divided into smaller flow channels, which reduces the turbulence caused by the uneven wave fluctuation, so as to increase the wind stability near the inlet and outlet of the arc channel, and further improve the power generation efficiency.

A further object of the present invention is to further provide a convex portion on one side of the base, and the base is provided with a concave portion on the other side of the convex portion for connecting the other bases on both sides of the base. By using the arrangement of the concave portion and the convex portion, the base can be laterally coupled to the other base, and then connected in plurality to form a breakwater, so that the present invention has an anti-wave effect in addition to generating electricity by natural phenomena.

The invention can be divided into two parts during the operation of power generation. First, the first part is to generate electricity by using the fluctuation of the waves: the waves enter the curved channel (11) from the inlet and outlet (12) of the base, due to the arc The passage (11) is recessed so that the seawater flowing in from the inlet and outlet (12) remains at the bottom of the curved passage (11), and the water column piston is airtightly sealed at one end of the curved passage (11).
