Description

Technical Field

[0001] This invention relates to a water-drawing structure for an ocean energy generator, which is a device that uses ocean waves as kinetic energy to draw water, thereby providing a water-drawing device for the operation of an ocean energy generator. Background Technology

[0002] The current mainstream power generation methods cause great pollution to the earth's environment. For example, nuclear power generation produces a lot of nuclear waste, and thermal power generation produces serious air pollution. As environmental awareness rises, countries around the world have successively developed green energy to replace existing power generation methods, such as solar energy, wind power, and hydropower, hoping to make green energy technology the main power generation technology.

[0003] Among green energy sources, hydropower is a promising project. Hydropower mainly relies on the water flow generated by the elevation difference of rivers and mountains to scour the waterwheel of a hydroelectric generator. The rotational kinetic energy generated by the waterwheel after being scourd can be converted into electricity by the equipment, thus achieving the effect of hydropower generation. However, traditional hydropower plants have very strict requirements for their location. In Taiwan, for example, most of the rivers are short and the geology is fragile. Therefore, most suitable locations for hydropower plants already have reservoirs built on them. Thus, for reservoirs, the priority of supplying domestic water is higher than power generation. As a result, most hydropower plants are unable to operate most of the time.

[0004] In view of the aforementioned problems, people have further developed ocean energy power generation based on the principle of hydropower. However, most of the current mainstream ocean energy power generation relies on the water level difference generated by the tides to generate kinetic energy. But the time of a single tide cycle is too long, so the efficiency is not very good. Therefore, it is necessary to further improve the efficiency of current ocean energy power generation. Summary of the Invention

[0005] This invention pertains to the water-drawing structure of an ocean energy generator. In practical applications, the positioning columns are fixed to the seabed, while the floating components float on the sea surface. As the ocean waves rise and fall, the combination of the floating components and the counterweights drives the main connecting rod to swing up and down, which in turn drives the piston to extend and retract relative to the outer cylinder, repeatedly sending seawater through the water pipe to the water collection tank. The seawater in the collection tank then continuously flows to the power generation waterwheel to achieve the purpose of generating electricity. This invention allows the ocean energy generator to continuously draw seawater to generate electricity simply by relying on the ocean waves. The ocean only needs wind to create waves, resulting in superior power generation efficiency compared to slow tidal changes, effectively improving the previous problem of poor ocean energy power generation efficiency.

[0006] To achieve the above objectives and effects, the present invention provides a water intake structure for an ocean energy generator, comprising: a water collection tank; a plurality of positioning columns respectively disposed at the bottom of the water collection tank; a water supply pipe having a check valve disposed inside, one end of the water supply pipe being connected to the interior of the water collection tank; a water intake assembly having one end connected to the water supply pipe; a float; a connecting rod assembly comprising a main connecting rod, a piston connecting rod, and a float connecting rod, one end of the main connecting rod being pivotally mounted on one of the positioning columns and the other end being pivotally connected to the float connecting rod, the other end of the float connecting rod being pivotally connected to the main connecting rod and connected to the float; one end of the piston connecting rod being connected to the water intake assembly and the other end of the piston connecting rod being pivotally connected to the main connecting rod; and a counterweight disposed at the end of the main connecting rod pivotally mounted on the float connecting rod.

[0007] Furthermore, the counterweight is connected to the float rod by a hook connection.

[0008] Furthermore, the water-drawing assembly includes an outer cylinder and a piston. One end of the outer cylinder is connected to the water supply pipe, and the other end has an inlet. The outer cylinder is provided with a water inlet that includes a backflow prevention function. The piston is partially and tightly inserted into the end of the outer cylinder with the inlet. One end of the piston rod is connected to the piston.

[0009] Furthermore, the inner wall of the outer cylinder is provided with two stop ribs, which respectively block the upward and downward displacement paths of the piston.

[0010] Furthermore, the water-drawing assembly includes a water-drawing software, one end of which is connected to the water supply pipe and the other end of which is connected to the piston rod. The water-drawing software is provided with a water inlet that includes a backflow prevention function. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0013] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of the invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0014] Please refer to Appendix 1 to Appendix 2 below. Figure 5 The water-drawing structure of the marine energy generator of the present invention is described.

[0015] As shown in Figures A to B, the present invention is a water-drawing structure for an ocean energy generator, comprising: a water collection tank 1; a plurality of positioning columns 2, respectively disposed at the bottom of the water collection tank 1; a water delivery pipe 3, wherein a check valve 31 is disposed inside the water delivery pipe 3, one end of the water delivery pipe 3 being connected to the interior of the water collection tank 1; a water-drawing assembly 4, one end of which is connected to the water delivery pipe 3; a float 5; and a connecting rod assembly 6, comprising a main connecting rod 61 and a piston. A connecting rod 62, a float connecting rod 63, one end of the main connecting rod 61 is pivotally mounted on one of the positioning pins 2 and the other end is pivotally connected to the float connecting rod 63, the other end of the float connecting rod 63 is pivotally connected to the main connecting rod 61 and connected to the float 5, one end of the piston connecting rod 62 is connected to the water-drawing assembly 4 and the other end of the piston connecting rod 62 is pivotally connected to the main connecting rod 61; a counterweight 64 is disposed at the end of the main connecting rod 61 where the float connecting rod 63 is pivotally mounted.

[0016] To facilitate understanding of the embodiments of the present invention, a first embodiment of a water-drawing assembly 4 is provided. The water-drawing assembly 4 includes an outer cylinder 41 and a piston 42. One end of the outer cylinder 41 is connected to the water supply pipe 3, and the other end has an inlet 411. The outer cylinder 41 is provided with a water inlet 412 that includes a backflow prevention function. The piston 42 is partially and tightly inserted into the end of the outer cylinder 41 with the inlet 411. One end of the piston rod 62 is connected to the piston 42.

[0017] The backflow prevention function of the water inlet 412 is to restrict seawater to enter the outer cylinder 41 only through the water inlet 412, while the seawater in the outer cylinder 41 cannot flow out of the outer cylinder 41 through the water inlet 412.

[0018] Continuing from the above description, the embodiments of the present invention are further detailed. As shown in Figure 1A, the present invention pertains to the water-drawing structure of an ocean energy generator. In practical applications, the water collection tank 1 is combined with the power generation waterwheel 7, while each positioning column 2 is fixed to the seabed. The floating component 5 floats on the sea surface 8, and one end of the main connecting rod 61 is pivotally mounted on one of the positioning columns 2. Therefore, as the sea surface 8 rises and falls with the waves, the combination of the floating component 5 and the counterweight 64 can drive the main connecting rod 61 to swing up and down. For example, as shown in Figure 1A, the sea surface 8 below the floating component 5 rises due to the wave crest, causing the floating component 5 to rise due to buoyancy, which in turn causes the floating component connecting rod 63 to drive the main connecting rod 61 to rise. The rise of connecting rod 61 will drive piston connecting rod 62 to push upward, thereby compressing piston 42 upward. In this way, seawater inside outer cylinder 41 will be sent into water supply pipe 3. The check valve 31 inside water supply pipe 3 can effectively prevent seawater from flowing back into outer cylinder 41. Continuing as shown in Figure 2A, when the trough of the wave passes below the float 5, the sea surface 8 below the float 5 will drop, and the float 5 will no longer be supported by buoyancy. At this time, the weight of counterweight 64 can cause main connecting rod 61 to swing downward. In this way, main connecting rod 61 will pull piston connecting rod 62 to drop, so that piston 42 is pulled downward, causing external seawater to flow into outer cylinder 41 from water inlet 412. As can be seen from the foregoing, the structure of the present invention utilizes wave undulations to cause the piston 42 to extend and retract relative to the outer cylinder 41, thereby repeatedly sending seawater through the water pipe 3 to the water collection tank 1. The seawater in the water collection tank 1 then continuously flows to the power generation waterwheel 7 to achieve the purpose of power generation. The present invention enables the ocean energy generator to continuously draw seawater to generate electricity simply by relying on ocean waves. The ocean only needs wind to create waves, which is much more efficient than the slow tidal changes. It effectively improves the problem of poor efficiency in previous ocean energy power generation. The present invention is novel and progressive.

[0019] As shown in the third figure, one of the multiple positioning posts 2 includes two positioning feet 22, and the main connecting rod 61 passes between the two positioning feet 22. The purpose of this structure is to limit the upward range of the main connecting rod 61 at the bottom of the main body 21, thereby stabilizing the main connecting rod 61.

[0020] The counterweight 64 is connected to the float rod 63 by a hook-and-loop connection to facilitate the replacement and installation of the counterweight 64.

[0021] As shown in Figure B, the inner wall of the outer cylinder 41 is provided with two stop ribs 413 (ring-shaped). The two stop ribs 413 respectively block the upward and downward displacement paths of the piston 42 to avoid excessive upward and downward movement of the piston 42 during displacement.

[0022] As shown in Figures 4 and 5, the water-drawing assembly 9 of the present invention has a second form, wherein the water-drawing assembly 9 includes a water-drawing software 91, one end of which is connected to the water supply pipe 3 and the other end is connected to the piston rod 62. The water-drawing software 91 is provided with a water inlet 911 including a backflow prevention function. The difference from the previous embodiment is that the outer cylinder 41 and the piston 42 are replaced by the water-drawing software 91.

[0023] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
