Description

Technical Field

[0001] The utility model relates to the technical field of power generation devices, in particular to a combined power generation device based on wave energy and solar energy. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] Existing wave energy power generation devices are mainly divided into oscillating water column type, oscillating float type, overboard type, pendulum type, duck type, raft type, etc. Among them, oscillating water column power generation is the most widely used wave energy power generation technology, which uses the up and down reciprocating motion of the water column in the device under the action of wave energy to compress the air in the upper air chamber, and then flows through the air outlet above the air chamber through the power generation device to realize the conversion of wave energy into electrical energy.

[0004] However, the single piston method that only uses the gas volume in the floating compressed air chamber on the water surface has low conversion efficiency, low power and low stability. At the same time, due to the strong uncertainty of waves, the generated air flow is also unstable, so the power generation power of a single wave energy power generation device is also unstable, reducing the power generation efficiency and quality. Utility Model Content

The movement of the skateboard at the wave trough and the design of the one-way water inlet are used to compress the seawater in the water inlet chamber to enter the water turbine power generation chamber for power generation. At the same time, the movement of the skateboard at the wave crest and the floating of the water surface in the air chamber are used to compress the gas volume in the air chamber, thereby realizing the power generation of the air turbine generator. Combined with the photovoltaic panels installed on the top plate of the air chamber, it integrates water turbine power generation, air power generation and solar power generation, thereby improving power generation efficiency and resource utilization.

[0013] As an optional embodiment, when the wave trough comes, the slide plate moves toward the second front wall plate under the action of the spring rod, so that the seawater in the water inlet chamber is compressed and enters the hydro-generator from the first bottom plate to drive the hydro-generator to generate electricity, and flows out of the hydro-generator room through the second bottom plate.

[0014] As an optional embodiment, the air chamber further includes a third bottom plate opposite to the top plate, and a channel for the inflow of seawater is provided between the third bottom plate and the rear wall plate.

[0015] As an optional implementation, a blocking diaphragm is provided on the third bottom plate, and the blocking diaphragm is used to limit the maximum displacement of the slide plate.

[0017] As an optional implementation, a circular hole is provided on the rear wall plate, the air turbine generator is placed coaxially with the circular hole, and the circular hole and the air turbine generator are sealedly connected.

[0018] As an optional embodiment, a third hole connected to the external space is provided on the top of the power generation rear chamber, so that the gas can flow from the air chamber through the air turbine generator to the power generation rear chamber, and then flow to the external space through the third hole, and the gas can enter the air turbine generator from the external space through the third hole and flow into the air chamber through the air turbine generator.

[0019] As an optional implementation, a baffle is provided at the one-way water inlet, and the top end of the baffle is connected to the first front wall panel via a rotating shaft so that the baffle swings up and down around the rotating shaft.

[0020] As an optional embodiment, when the wave crest comes, the baffle moves upward around the rotating axis under the impact of seawater, so that seawater enters the water inlet chamber through the one-way water inlet, whereby the slide moves toward the rear wall under the action of seawater and the spring rod is compressed, and the volume of gas in the air chamber decreases. At the same time, after seawater flows into the air chamber from the bottom of the air chamber, the water level at the bottom of the air chamber rises, and the volume of gas in the air chamber decreases, so that the gas flows into the air power generation chamber through the rear wall;

[0021] When the wave trough comes, the baffle moves downward around the rotating axis to close the one-way water inlet, and the slide plate moves toward the second front wall panel under the action of the spring rod.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] The utility model proposes a combined power generation device based on wave energy and solar energy. Under the action of wave energy, seawater acts on the skateboard, causing the skateboard to move toward the rear wall, the spring rod is compressed, and the volume of gas in the air chamber is reduced. At the same time, seawater flows into the air chamber from the bottom of the air chamber, the water level at the bottom of the air chamber rises, and the volume of gas in the air chamber is further reduced. The up and down floating of the water surface in the air chamber and the movement of the skateboard into the air chamber under the action of waves to compress the volume of gas in the air chamber are used, thereby pushing the air in the air chamber to flow toward the air turbine generator, driving the air turbine generator to generate electricity. The utility model is a double-piston device that uses the movement of the skateboard and the floating of the water surface to simultaneously compress the volume of gas in the air chamber. Compared with a single-piston device that only uses the floating of the water surface to compress the volume of gas in the air chamber, it has the characteristics of high conversion efficiency, good stability, and high power.

[0024] When the wave crest comes, the air volume in the air chamber is compressed by the movement of the skateboard, and the water level in the air chamber rises under the action of the wave to reduce the air volume in the air chamber, thereby pushing the air to flow to the air turbine generator, driving the generator to generate electricity; when the wave trough comes, the air volume in the air chamber is increased by the reverse movement of the skateboard, and at the same time the water level at the bottom of the air chamber drops, and the gas volume in the air chamber is further increased. At this time, the gas enters the air turbine generator from the external space through the power generation rear chamber, drives the air turbine generator to generate electricity, and then flows into the air chamber through the air turbine generator; and when the skateboard moves in the reverse direction, since the water inlet chamber is a one-way water inlet, the seawater in the water inlet chamber is compressed and enters the water turbine power generation chamber to generate electricity; combined with the utility model, photovoltaic panels are installed on the top plate of the air chamber to generate electricity using solar energy; thus, the device is based on wave energy and solar energy, integrates water turbine power generation, air power generation and solar power generation, obtains a larger output power and a more stable output power, improves power generation efficiency and resource utilization, and effectively solves the safety problems brought by a single wave energy power generation device to the power grid.

[0033] In the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0034] Example 1

[0035] like Figure 1-Figure 2 As shown, this embodiment provides a combined power generation device based on wave energy and solar energy, comprising: a water intake chamber 1, a water turbine power generation chamber 2, an air chamber 3, an air power generation chamber and a photovoltaic panel 6;

[0036] The water inlet chamber comprises a first front wall plate 7 and a first bottom plate 8, wherein the first front wall plate 7 is arranged on the wave-facing side, and a one-way water inlet 9 is arranged on the first front wall plate 7, and the first bottom plate 8 is connected to the water turbine power generation chamber 2;

[0037] The bottom of the air chamber 3 is hollow, and includes a second front wall panel 14, a rear wall panel 15, a top panel 16 and a slide plate 19; the second front wall panel 14 is connected to the water inlet chamber 1, the second front wall panel 14 and the slide plate 19 are arranged opposite to each other, both ends of the slide plate 19 are connected to the rear wall panel 15 through a spring rod 20, the rear wall panel 15 is connected to the air power generation chamber, and a photovoltaic panel 6 is provided on the top panel 16.

[0038] In this embodiment, the water inlet chamber 1 includes: a first front wall panel 7, a first bottom panel 8, a side wall panel 18 and other side walls; wherein the first front wall panel 7 and the side wall panel 18 are vertically arranged, and the other side walls are side walls arranged opposite to the first bottom panel 8, and side walls perpendicular to the first front wall panel 7 and opposite to the side wall panel 18.

[0039] In this embodiment, a one-way water inlet 9 is provided on the first front wall panel 7 , which only allows seawater to enter. When a wave crest comes, seawater enters the water inlet chamber 1 through the one-way water inlet 9 .

[0040] As an optional implementation, a baffle 22 is provided at the one-way water inlet 9, and the top end of the baffle 22 is connected to the first front wall panel 7 via a rotating shaft so that the baffle 22 swings up and down around the rotating shaft.

[0041] It can be understood that when the wave crest comes, the seawater impacts the baffle 22, causing the baffle 22 to move upward around the rotating axis, so that the seawater can enter the water inlet chamber 1 through the one-way water inlet 9; and when the wave trough comes, the seawater recedes, and under the action of gravity, the baffle 22 moves downward around the rotating axis, closing the one-way water inlet 9, so that the seawater can no longer flow back to the ocean through the one-way water inlet 9.

[0042] In this embodiment, the water turbine power generation chamber 2 includes: a second bottom plate 10 arranged opposite to the first bottom plate 8, and two pairs of side walls arranged perpendicular to and opposite to the second bottom plate 10;

[0043] A hydro-generator 12 is disposed in the hydro-generating chamber 2 . One end of the hydro-generator 12 is connected to the first bottom plate 8 via a first pipe 11 , and the other end of the hydro-generator 12 is connected to the second bottom plate 10 via a second pipe 13 .

[0044] Since the seawater entering the water inlet chamber 1 through the one-way water inlet 9 can no longer return to the sea through the one-way water inlet 9, it can enter the hydro-generator 12 through the first pipe 11 and drive the hydro-generator 12 to generate electricity, and then flow out of the hydro-generator chamber 2 from the inside of the hydro-generator 12 through the second pipe 13 and enter the ocean.

[0045] As an optional implementation, a hole is opened in the middle of the first bottom plate 8, and the hole is used for passing the first pipe 11 to connect with the hydro-generator 12.

[0046] As an optional implementation, a hole is opened in the middle of the second bottom plate 10, and the hole is used for passing the second pipe 13 to connect with the hydro-generator 12.

[0047] In this embodiment, the air chamber 3 includes: a second front wall plate 14, a rear wall plate 15, a top plate 16, a third bottom plate 17, a side wall plate 18 and a slide plate 19;

[0048] The second front wall panel 14 is arranged opposite to the rear wall panel 15 , the second front wall panel 14 is arranged perpendicular to the side wall panel 18 , the top panel 16 is arranged opposite to the third bottom panel 17 , and a channel for seawater to flow in is provided between the third bottom panel 17 and the rear wall panel 15 .

[0049] The two ends of the slide plate 19 are connected to the rear wall panel 15 through a spring rod 20. The second front wall panel 14 is arranged opposite to the slide plate 19, and a hollow is arranged in the middle of the second front wall panel 14 to communicate with the water inlet chamber 1 for passing seawater so that the seawater directly impacts the slide plate 19. The slide plate 19 moves toward the rear wall panel 15 under the impact of the seawater.

[0050] It can be understood that when the wave crest comes, seawater rushes into the water inlet chamber 1, and impacts the slide plate 19 forward under the action of inertia, so that the slide plate 19 moves toward the rear wall plate 15 under the impact of seawater; at the same time, although seawater will also flow into the hydro-turbine power generation chamber 2 through the holes on the first bottom plate 8 under the action of gravity, the holes on the first bottom plate 8 are small, and the amount of seawater flowing into the hydro-turbine power generation chamber 2 is small, which is not enough to drive the hydro-turbine generator 12 to generate electricity, and more seawater impacts the slide plate 19 forward under the action of inertia;

[0051] Then, when the wave trough comes, the pressure of the sea water on the slide plate 19 becomes smaller, and the slide plate 19 moves toward the second front wall plate 14 under the action of the spring rod 20. Since the one-way water inlet 9 is closed, the pressure in the water inlet chamber 1 increases, and the sea water flows into the turbine power generation chamber 2 through the holes on the first bottom plate 8.

[0052] As an optional implementation, a blocking partition is provided on the third bottom plate 17 to limit the maximum displacement of the slide plate 19 and prevent the slide plate 19 from sliding out of the air chamber 3 .

[0053] As an optional implementation, the spring rod 20 is a nitrogen spring rod, which can not only play the role of a spring, but also ensure that the slide plate 19 is stable when the slide plate 19 slides and does not fall over.

[0054] As an optional embodiment, the bottom of the air chamber 3 is submerged in seawater.

[0055] In this embodiment, the photovoltaic panel 4 is installed on the top plate 16 through a photovoltaic bracket, and the photovoltaic panel 4 can face the south to obtain a larger power generation power.

[0056] In this embodiment, the air power generation chamber includes a power generation front chamber 4 and a power generation rear chamber 5. An air turbine generator 21 is provided in the power generation front chamber 4. One end of the air turbine generator 21 is connected to the air chamber 3.

[0057] Specifically, a circular hole is opened on the rear wall panel 15 for communicating with the power generation front chamber 4, the air turbine generator 21 is placed coaxially with the circular hole on the rear wall panel 15, and the circular hole on the rear wall panel 15 and the air turbine generator 21 are sealed and connected.

[0058] In this embodiment, the other end of the air turbine generator 21 is connected to the power generation rear chamber 5. A hole is provided on the top of the power generation rear chamber 5 to communicate with the external space. The air flows from the air chamber 3 through the air turbine generator 21 to the power generation rear chamber 5, and then flows to the external space through the hole on the top of the power generation rear chamber 5.

[0059] Similarly, the gas enters the air turbine generator 21 from the external space through the holes at the top of the power generation rear chamber 5, and then flows into the air chamber 3 through the air turbine generator 21.

[0060] In this embodiment, the above device is installed as a whole on the coast, and its bottom is submerged in the sea water. The power generation method includes:

[0061] When the wave crest comes, the baffle 22 is impacted by the seawater, causing the baffle 22 to move upward around the rotation axis, and the seawater enters the water inlet chamber 1 through the one-way water inlet 9 of the water inlet chamber 1. At this time, the seawater rushing into the water inlet chamber 1 acts on the slide plate 19, causing the slide plate 19 to move toward the rear wall plate 15, the spring rod 20 is compressed, and the volume of the gas in the air chamber 3 is reduced;

[0062] At the same time, when the wave crest comes, seawater flows into the air chamber 3 through the channel between the third bottom plate 17 and the rear wall plate 15, the water level at the bottom of the air chamber 3 rises, and the volume of gas inside the air chamber 3 is further reduced;

[0063] Thus, the gas flows from the inside of the air chamber 3 through the circular holes on the rear wall panel 15 into the air turbine generator 21 to drive the air turbine generator to generate electricity. Finally, the gas flows from the air turbine generator 21 to the power generation rear chamber 5 and flows out from the holes on the power generation rear chamber 5.

[0064] When the wave trough comes, the pressure of the sea water on the slide plate 19 becomes smaller, and the slide plate 19 moves toward the second front wall plate 14 under the action of the spring rod 20, and the volume of the gas in the air chamber 3 increases;

[0065] At the same time, when the wave trough comes, the water level at the bottom of the air chamber 3 drops, and the volume of the gas in the air chamber 3 further increases;

[0066] Thus, the gas enters the air turbine generator 21 from the outside through the holes on the power generation rear chamber 5, drives the air turbine generator 21 to generate electricity, and finally flows into the air chamber 3 through the air turbine generator 21.

[0067] Also, when the wave trough comes, the seawater recedes, and under the action of gravity, the baffle 22 moves downward around the rotating axis to close the one-way water inlet 9. When the slide plate 19 moves toward the second front wall plate 14, the seawater in the water inlet chamber 1 is compressed and enters the hydro-generator 12 through the holes in the first bottom plate 8 through the first pipe 11 to drive the hydro-generator 12 to generate electricity, and the seawater flows out of the hydro-generator chamber 2 from the inside of the hydro-generator 12 through the second pipe 13 and into the ocean.

[0068] In this embodiment, the device is based on wave energy and solar energy, integrating water turbine power generation, air power generation and solar power generation, improving power generation efficiency and resource utilization. The generated power can be connected in parallel to the same battery, and the whole is powered by the battery, which in turn powers the user.

[0069] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
