Description

Underwater floating type generator
The first, the field:
the present invention relates to generators that generate electrical energy from water hammering.
Secondly, background:
the existing hydroelectric generators utilizing the kinetic energy of water wave shock waves to generate electric energy are various, but because the water level changes frequently and repeatedly, the energy-absorbing rotating blades cannot change along with the change of the water level or the wave position, so that the impact energy of absorbing water is greatly reduced, and the generated electric energy is very limited.
Thirdly, the invention content:
the invention aims to solve the problems that: the influence of frequent and repeated changes of the water level on the generated energy is reduced, and the cost performance of the power generation equipment is improved.
In order to solve the problems, the working principle of the invention is that the axis position of the rotating blade is always near the water level under the buoyancy action of the air box, and the position of the rotating blade automatically moves up and down along with the height of the water level, so that the thrust borne by the rotating blade is always the maximum. According to the working principle, the technical scheme is as follows: the fixing device is arranged on the ground of water, the lifting device can move up and down along the fixing device, the power generation device is arranged on the fixing device, and the air box in the lifting device is a sealed box filled with air. No matter how the water level changes, the buoyancy generated by the air raises the rotating blades to the water surface position, the waves can always hit the rotating blades, and the rotating blades drive the generator to generate electricity.
By adopting the method, no matter how the water level changes, the rotating blade is always near the water level under the action of the lifting force of the air box, the rotating blade can absorb the maximum wave thrust, and the generated electric power is maximum. The cost performance of the product is greatly improved.
Fourthly, explanation of the attached drawings:
FIG. 1 is a schematic diagram of a floating in water or power generator 1 according to an embodiment of the present invention;
FIG. 2 is a partial cross-sectional view of a first embodiment of the underwater floatation or electric generator 1 of the present invention;
fig. 3 is a partial block diagram of an embodiment 2 of the invention of an underwater floatation or power generator.
Fifth, the embodiment:
in the embodiment 1 shown in fig. 1 to fig. 2, the underwater floating generator of the invention comprises a power generation device (1), a fixing device (2), a lifting device (3) and a water blocking device (4); the power generation device (1) comprises a power generator (1-1), a shaft (1-2), a bearing assembly (1-3), a rotating blade (1-4), a shaft end nut (1-5), a mounting bolt (1-6) and a key (1-7); the fixing device (2) comprises a support rod (2); the lifting device (3) comprises a supporting sleeve (3-1), an air box (3-2), a bolt (3-3) and a supporting frame (3-4); the water retaining device (4) comprises a water retaining plate (4-1) and a bolt (4-2). The supporting rod (2) is fixed on the water bottom, the supporting sleeve (3-1) is sleeved outside the supporting rod (2), and the supporting sleeve (3-1) can slide up and down along the supporting rod (2) but cannot rotate around the supporting rod. The gas box (3-2) is arranged on the supporting sleeve (3-1) through a bolt (3-3), and the supporting frame (3-4) is welded on the supporting sleeve (3-1); the generator (1-1) is arranged on the supporting frame (3-4) through the mounting bolts (1-6), the bearing assembly (1-3) is arranged on the supporting frame (3-4) through the mounting bolts (1-6), the shaft (1-2) passes through the bearing assembly (1-3) and the rotating blades (1-4) and then passes through the bearing assembly (1-3) and is loaded into the shaft end nut (1-5), the hole at the end part of the shaft (1-2) is sleeved on the output shaft of the generator (1-1), a key (1-7) is arranged between the rotating blades (1-4) and the shaft (1-2), a key (1-7) is arranged between the shaft (1-2) and the generator (1-1), and the water baffle plate (4-1) is arranged on the supporting frame (3-4) through a bolt (4-2). The middle of the gas box (3-2) is a hollow body; the position B-B in the figure is the horizontal position. As the whole product is not moved except the supporting rod (2), other parts move up and down along with the height of the water surface under the buoyancy action of the air box (3-2), the lower half parts of the rotating blades (1-4) enter the water, and the side of the position above the shaft (1-2) is above the water surface. Sometimes, when the water surface high pressure is low, the generator can automatically adjust the height, so that the lower half parts of the rotating blades (1-4) are always in the water, and the side of the position above the shaft (1-2) is above the horizontal plane. Thus, when waves are hit, the upper parts of the rotating blades (1-4) are blocked by the water baffle (4-1), and the rotating blades (1-4) on the lower half part rotate under the action of water to drive the generator (1-1) to generate electricity.
In the 2 nd embodiment of fig. 3, it is different from the 1 st embodiment in that: the whole power generation device (1) rotates ninety degrees, the rotating blades (1-4) are transversely arranged, and the shaft ends of the rotating blades (1-4) are directly connected with the power generator (1-1) through bolts (1-6) and nuts (1-9). Thus, the diameter and width of the rotating blades (1-4) can be made large, and the energy of the suction is relatively large.
The present invention is not limited to the above forms, but when in embodiment 1, the shaft (1-2) is provided with a plurality of rotating blades (1-4); when the lifting force of the air box (3-2) is not air, but a material with a specific gravity smaller than that of water is adopted; when the water retaining device (4) is not arranged on the supporting frame (3-4), but arranged on the ground at the bottom of the water; the invention is also provided when the power generation form in the power generation device is other forms.
