Description

Technical Field

[0001] The present invention relates to the technical field of wave energy power generation, and in particular to an integrated device for breaking ice and collecting wave energy. Background Art

[0002] With the development of the global economy and the increase in population, energy demand is surging worldwide. At the same time, fossil fuels are becoming increasingly scarce. To conserve energy and protect the environment, people are turning their attention from land to the ocean, exploring its resources for human use. Wave energy, a clean, renewable energy source, boasts abundant reserves, with globally available wave energy between 2 and 3 billion kilowatts. Currently, the world's major wave energy devices can be categorized into three types based on their location: offshore (over 2.5 kilometers offshore), nearshore, and shore-based.

[0003] Nearshore wave energy devices have seen significant development due to their ease of installation and maintenance, and low construction costs. However, when parts of the ocean freeze in winter, the use of wave energy harvesting devices is restricted, forcing them to sit idle. This idleness also incurs maintenance and repair costs, resulting in economic losses. Furthermore, when the ocean freezes, offshore platforms can easily become covered with ice, impacting equipment operation and even directly affecting the safety of marine structures. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an integrated device for breaking ice and collecting wave energy in response to the shortcomings of the above-mentioned existing technologies. The device can not only collect waves but also be converted into an ice-breaking and ice-proof device when the sea surface is frozen, thereby achieving the purpose of dual use in one machine and reducing resource waste.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is:

[0006] An integrated device for icebreaking and collecting wave energy, comprising a column and a wave energy power generation body mounted on the column; the wave energy power generation body is formed by a plurality of power generation units surrounded along the circumference of the column;

[0007] The power generation unit includes a power generation cabin, a connecting rod structure and a float; the power generation cabin is arranged inside the column, and a generator is provided in the power generation cabin; one end of the connecting rod structure is connected to the generator and the other end is connected to the float, and the mechanical energy of the float is transmitted to the generator and converted into electrical energy. The connecting rod structure includes a first connecting rod, a second connecting rod and a third connecting rod, the lower end of the first connecting rod is hinged to the power generation cabin and is connected to the input shaft of the generator, the upper end of the first connecting rod is hinged to one end of the second connecting rod, the other end of the second connecting rod is hinged to one end of the third connecting rod, and is hinged to the float at the same time, and the other end of the third connecting rod is provided with a sliding member, and the sliding member has a built-in driving member, and the driving member is used to drive the other end of the third connecting rod to move along the first connecting rod, so that the power generation unit switches between the power generation state and the ice breaking state:

[0008] When the power generation unit is in the power generation state, the other end of the third connecting rod moves to the lower end of the first connecting rod, the three connecting rods form a triangle, and the float is unfolded. At this time, the float is in the shape of an upper cylinder and a lower cone;

[0009] When the power generation unit is in the ice-breaking state, the other end of the third connecting rod moves to the upper end of the first connecting rod, the three connecting rods overlap, and the float is retracted outside the column. At this time, the float is in the shape of an upper frustum and a lower inverted frustum.

[0010] In the above scheme, a movable transmission rack is provided in the power generation cabin, and the input shaft of the generator is engaged with the transmission rack; a cam is provided at the lower end of the first connecting rod, and the cam is in contact with the transmission rack. The cam can rotate synchronously with the first connecting rod, thereby driving the transmission rack to move synchronously, and then driving the input shaft to rotate.

[0011] In the above scheme, the transmission rack is arranged vertically and can move back and forth in the vertical direction; a first baffle is installed at a certain distance above the input shaft, and the upper end of the transmission rack passes through the first baffle. When the power generation unit is in the ice-breaking state, the transmission rack moves to the lowest position, and at this time the upper end of the transmission rack contacts the first baffle.

[0012] In the above solution, the cam is welded to the bottom end of the first connecting rod.

[0013] In the above solution, a second baffle is further provided at the lower end of the first connecting rod to limit the movement of the third connecting rod while avoiding damage to the cam.

[0014] In the above solution, the first connecting rod is provided with a sliding groove or track adapted to the sliding member.

[0015] In the above solution, the driving member built into the sliding member is automatically controlled by a control system.

[0016] In the above solution, 4 to 8 power generation units are arranged along the circumference of the column, and each power generation unit is independent of each other.

[0017] In the above solution, the upper end of the first connecting rod is hinged to one end of the second connecting rod through a first hinge; the other end of the second connecting rod is hinged to one end of the third connecting rod through a second hinge.

[0018] In the above solution, a wind turbine is installed on the top of the column.

[0019] The beneficial effects of the present invention are:

[0020] 1. The present invention uses a specially designed connecting rod structure to realize the expansion or contraction of the float. When the sea is ice-free, the connecting rod structure drives the float to expand and collect wave energy. When the sea surface is frozen, the connecting rod structure drives the float to be contracted to the outside of the column. The outer structure of the float can be used for ice breaking and anti-icing, preventing the device from being damaged by ice.

[0033] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0034] like Figure 1-2 As shown, an integrated device for icebreaking and collecting wave energy provided by an embodiment of the present invention includes a column 200 and a wave energy power generation body installed on the column 200. The column 200 is installed on a seabed foundation; the wave energy power generation body is formed by a number of power generation units 100 surrounded along the circumference of the column 200.

[0035] like Figure 3-6 As shown, the power generation unit 100 includes a power generation cabin 30, a connecting rod structure 20 and a float 10. The power generation cabin 30 is arranged inside the column 200, and a generator (not shown) is arranged in the power generation cabin 30. One end of the connecting rod structure 20 is connected to the generator and the other end is connected to the float 10, transmitting the mechanical energy of the float 10 to the generator and converting it into electrical energy. Specifically, the connecting rod structure 20 includes a first connecting rod 21, a second connecting rod 22 and a third connecting rod 23. The lower end of the first connecting rod 21 is hinged to the power generation cabin 30 and is transmission-connected to the input shaft 31 of the generator. The upper end of the first connecting rod 21 is hinged to one end of the second connecting rod 22 through a first hinge 26, and the other end of the second connecting rod 22 is hinged to one end of the third connecting rod 23 through a second hinge 27, and is simultaneously hinged to the float 10. The other end of the third connecting rod 23 is provided with a sliding member (not shown in the figure), and the sliding member has a built-in driving member (not shown in the figure). The driving member is used to drive the other end of the third connecting rod 23 to move along the first connecting rod 21, so that the power generation unit 100 switches between the power generation state and the ice breaking state:

[0036] When the power generation unit 100 is in the power generation state, see Figure 3-4 , the other end of the third connecting rod 23 moves to the lower end of the first connecting rod 21, the three connecting rods form a triangle, and the float 10 is unfolded. At this time, the float 10 is in the shape of an upper cylinder and a lower cone;

[0037] When the power generation unit 100 is in the ice breaking state, see Figure 5-6The other end of the third connecting rod 23 moves to the upper end of the first connecting rod 21, the three connecting rods overlap, and the float 10 is retracted. At this time, the float 10 is in the shape of an upper frustum and a lower inverted frustum.

[0038] Further optimization, in this embodiment, a movable transmission rack 32 is provided in the power generation cabin 30, and a gear is provided on the input shaft 31 of the generator to engage with the transmission rack 32; a cam 24 is welded to the lower end of the first connecting rod 21, and the cam 24 is in contact with the transmission rack 32. The cam 24 can rotate synchronously with the first connecting rod 21, thereby driving the transmission rack 32 to move synchronously, and then driving the input shaft 31 to rotate, thereby realizing the transmission of mechanical energy of the float 10 to the generator.

[0039] Further optimized, in this embodiment, the transmission rack 32 is arranged vertically and can move back and forth in the vertical direction; a first baffle 33 is installed a certain distance above the input shaft 31, and the upper end of the transmission rack 32 passes through the first baffle 33. When the power generation unit 100 is in the ice-breaking state, the transmission rack 32 moves to the lowermost position, and at this time the upper end of the transmission rack 32 contacts the first baffle 33.

[0040] For further optimization, in this embodiment, a second baffle 25 is further provided at the lower end of the first connecting rod 21 to limit the movement of the third connecting rod 23 and avoid damaging the cam 24.

[0041] Further optimization, in this embodiment, a sliding groove or track adapted to the sliding member is provided on the first connecting rod 21. The sliding member can be a pulley.

[0042] Further optimized, in this embodiment, the driving member built into the sliding member is automatically controlled by the control system.

[0043] Further optimized, in this embodiment, 4 to 8 power generation units 100 are arranged along the circumference of the column 200, and each power generation unit 100 is independent of each other.

[0044] For further optimization, in this embodiment, a wind turbine 300 is installed on the top of the column 200 , and the wave energy power generation body is installed in the middle of the column 200 .

[0045] The working principle of the integrated device for icebreaking and collecting wave energy of the present invention is as follows:

[0046] See also Figure 3-4In actual use, when there is no ice in the sea, the device is used to collect wave energy. When the sea is frozen, the retracted mode of the float 10 is opened, and the sliding member connected to the third link 23 moves on the first link 21 under the drive of the driving member, sliding from the end close to the first hinge 26 to the end close to the cam 24. When the sliding member slides to the second baffle 25, it is blocked and stops moving. At this time, the second link 22 connected to the first link 21 through the first hinge 26 is stretched open, and the first link 21, the second link 22 and the third link 23 form a triangle; the float 10 hinged by the second hinge 27 is driven by the link structure 20 and with the help of its own gravity, so that the top of the cone of the lower half of the float 10 points to the sea level.

[0047] Working principle: When the sea is ice-free, the device is in the state of unfolding the float 10, and the first connecting rod 21, the second connecting rod 22 and the third connecting rod 23 form a triangle. Due to the stability of the triangle, the three connecting rods will always form a triangle when collecting wave energy. When there is no wave action, the buoyancy and gravity of the float 10 reach a balanced state, and the float 10 remains motionless. When waves are transmitted to the wave energy device, the float 10 will move up and down with the change of water surface elevation, thereby driving the connecting rod structure 20 to reciprocate around the rotating shaft of the cam 24, driving the transmission rack 32 to reciprocate up and down. When the wave crest passes through the position where the float 10 is located, the balance of force exerted on the float 10 is broken under the combined action of dynamic water pressure and hydrostatic pressure, and the float 10 accelerates upward, thereby causing the connecting rod structure 20 to rotate counterclockwise. As the connecting rod structure 20 rotates, the cam 24 also rotates. The transmission rack 32 in contact with the cam 24 moves downward and drives the gearbox input shaft 31 to rotate, and the power is transmitted to the generator through the gearbox. The generator rotates to generate electricity. As the wave crest continues to propagate, float 10 accelerates downward as the water level drops, driving connecting rod structure 20 to rotate clockwise until float 10 reaches the trough. During this process, transmission rack 32 moves upward, also driving gearbox input shaft 31 to rotate in the opposite direction of the above process, and the gearbox drives the generator to generate electricity. In this way, transmission rack 32 enters a reciprocating cycle with the action of the waves, continuously driving gearbox input shaft 31 to rotate, and the gearbox transmits the power to the generator, causing the generator to operate and output electricity.

[0048] See also Figure 5-6When there is ice in the sea, the device is used to break ice and prevent ice, and the float 10 is retracted from its expanded state when there is no ice in the sea. The sliding member connected to the third link 23 moves on the first link 21 under the drive of the driving member, from the end close to the cam 24 to the end close to the first hinge 26. At this time, the third link 23 gradually overlaps with the second link 22, and the first link 21 gradually rotates to a vertical direction under the action of the third link 23, and fits against the side of the column 200. When the sliding member moves to one end of the first hinge 26, the first link 21, the second link 22 and the third link 23 overlap, rotate to a vertical direction, and fit against the side of the column 200. At this time, the transmission rack 32 moves downward until it is blocked by the first baffle 33. The float 10 connected to the second hinge 27 rotates 90 degrees counterclockwise so that the bottom surface of the cone of the float 10 is perpendicular to the sea level. It should be noted that Figure 4 In order to show the state of a single float being retracted, the float between the two floats is hidden.

[0049] Working principle: When there is ice in the sea, the device is in the state of folding the float 10, the first connecting rod 21, the second connecting rod 22 and the third connecting rod 23 overlap, rotate to the vertical direction, and fit on the side of the column 200. The bottom surface of the cone of the float 10 is perpendicular to the sea level. Figure 1 The upper center section is a true frustum, while the lower section is an inverted frustum, with the connecting ridges flush with sea level. When sea ice drifts toward the device, the cone changes the ice's failure mode from compression and bending to bending, reducing the ice load and breaking it apart. The broken ice flows along the sides of the device, thus performing both ice-breaking and ice-prevention functions. Once the sea ice season passes, the multiple floats 10 on the device can be deployed to harvest wave energy.

[0050] In this way, the device can function both when the sea is frozen and when the sea is ice-free, achieving dual use of one machine.

[0052] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are protected by the present invention.
