Description

Tidal power generation device and container assembly for accommodating power generation equipment

Background

At present, people's environmental awareness is gradually improved, and part of the national governments are pushing clean green energy to generate electricity, so in addition to wind power and solar energy power generation, tidal power generation is also gradually emphasized. Tidal power generation is a form of hydroelectric power generation from which energy is extracted by the movement of tidal currents or the elevation of the tidal sea surface. Although not widely used at present, tidal power has a good potential for future power supplies. In addition, tidal power generation is easier to predict than wind energy and solar energy, so that the tidal power generation is more suitable for power dispatching.

Tidal power generation has two main forms, one being tidal current power generation and the other being weir power generation. Tidal current power generation is to use tidal current to flow to push a thrust plate so as to provide a generator of power generation equipment to convert kinetic energy into electric energy, and weir dam power generation is to convert potential energy of the height of the tidal water level into electric energy. The dam type power generation has more influence on the ecology, so the tidal current type power generation is mostly used at present, however, the thrust plate used by the tidal current type power generation is easy to damage due to overlarge water flow thrust, and the maintenance cost is higher.

Detailed Description

The invention provides a tidal power generation device which comprises a container assembly and power generation equipment, wherein the power generation equipment is arranged in the container assembly. The water flow inlet of the container assembly is used for allowing tidal water flow to enter, and the inlet guide plate of the container assembly can lead the water flow to advance towards the power generation equipment so as to push the thrust plate of the power generation equipment and drive the thrust plate traction mechanism of the power generation equipment, so that the generator of the power generation equipment converts kinetic energy into electric energy. After the thrust plate of the power generation equipment is pushed by water flow, the water flow enters the pressure accumulation pool of the container assembly, then the water flow in the pressure accumulation pool passes through the backflow guide plate of the container assembly and then continues to flow to the first pressure relief pool of the container assembly so as to continue to push the thrust plate of the power generation equipment. Through the design of the inlet guide plate and the backflow guide plate, the water flow direction can be effectively guided, the effect of buffering overlarge water flow thrust is generated, and the technical problem of avoiding the damage of the thrust plate is achieved.

In order to further prevent the thrust force of the water flow from being too large and causing damage to the thrust plate, in at least one embodiment, the following steps are selected: the backflow guide plate is further provided with a one-way valve so as to guide the water flow of the pressure storage tank to a second pressure relief tank of the container assembly when the water flow thrust is overlarge; the container assembly is provided with more than two water inflow inlets and an inlet guide plate for confluence, and the inlet guide plate is provided with a one-way valve for reducing the water flow thrust after confluence; before the water flow at the water flow inlet reaches a thrust plate of the power generation equipment, the water flow thrust can be reduced by the slope-shaped ascending guide plate; and/or the thrust plate is pivoted with the damper so as to change the angle between the thrust plate and the horizontal plane when the water flow thrust is overlarge, so that all or part of the water flow can directly pass through the damper. It will be appreciated by those skilled in the art having the benefit of this disclosure that at least one of the foregoing may naturally be used alternatively to incorporate the tidal power plant as described above. However, under the condition that the material of the thrust plate is less likely to be damaged, those skilled in the art may not adopt any of the above methods.

Next, the present invention will be described in more detail with reference to other embodiments. Referring to fig. 1 and 2A, fig. 1 is a schematic perspective view of a tidal power generation device according to a first embodiment of the present invention, and fig. 2A is a schematic top view of the tidal power generation device according to the first embodiment of the present invention. The tidal power generation device 1 includes a container assembly (composed of a bottom plate (no reference number), an inlet wave height adjusting plate 101, an inlet guide plate 102, ocean current

side guide plates

104, 109, a backflow guide plate 105, backflow

side guide plates

106, 115, and an outlet wave height adjusting plate 107), and a power generation device (composed of a power control room 103, a plurality of thrust plates 108, a thrust plate traction mechanism 110, and a generator 113). The power generating device is accommodated in the container assembly, for example, disposed between the left and right sides of the container assembly, and the power generating device further has a frame (no reference symbol, such as a square frame in fig. 1) for being fastened or locked to the container assembly by the frame to fix the container assembly and the power generating device.

The inlet wave height adjusting plate 101, the ocean current

side guide plates

104 and 109, the outlet wave height adjusting plate 107 and the bottom plate form a substantially rectangular container, and the inlet guide plate 102, the return guide plate 105 and the return

side guide plates

106 and 115 are disposed in the container, thereby forming a container assembly. The inlet wave height adjustment plate 101 is located on the right side of the container assembly and is vertically movable to adjust the inflow of the water flow WD through the water flow inlet F _ IN and limit the flow of excessively high waves from entering the container assembly. The current

side guide plates

104 and 109 are located at the upper and lower sides of the container assembly and are connected to the inlet wave height adjusting plate 101 and the outlet wave height adjusting plate 107. The outlet wave height adjustment plate 107 is located on the left side of the container assembly and is vertically movable to adjust the discharge of the water flow WD OUT of the water flow outlet F _ OUT and to limit the excessive wave flow WD from entering and exiting the container assembly. The outlet wave height adjusting plate 107 and the water outlet F _ OUT may be optional components of the present invention and are replaced by a fixed ocean current side guide plate, or directly by the return flow guide plate 105, in which case the return flow guide plate 105 is also located on the left side of the container assembly.

The inlet guide plate 102 is disposed obliquely and has an angle with the transverse extending direction of the container assembly (i.e., the normal of the water flow inlet F _ IN), and is disposed between the position of the container assembly accommodating the power generation equipment and the inlet wave height adjusting plate 101, and between the ocean current

side guide plates

104 and 109, so as to guide the water flow WD to the thrust plate 108 of the power generation equipment. The backflow guide plate 105 is disposed obliquely, forms an included angle with the transverse extending direction of the container assembly, and is disposed between the position of the container assembly for accommodating the power generation equipment and the outlet wave height adjusting plate 107, and between the seawater

side guide plates

104 and 109, so as to guide the water flow WD pushing the thrust plate 108 to the thrust plate 108 of the power generation equipment again. The return guide plate 115 is disposed obliquely and has an angle with the transverse extension direction of the container assembly, and is connected between the return guide plate 105 and the ocean current guide plate 104 to make the water flow WD more easily flow to the thrust plate 108 of the power generation equipment. The return flow side guide plate 106 is arranged obliquely with an angle to the transverse extension direction of the container assembly and is connected between the return flow guide plate 105 and the ocean flow side guide plate 109 to make the water flow WD more easily flow to the thrust plate 108 of the power generation equipment. The

return side tabs

115, 106 may be unnecessary components in the present invention and can be removed.

The area surrounded by the container assembly accommodating the power generation equipment, the outlet wave height adjusting plate 107, the ocean current side guide plate 104 and the backflow guide plate 105 defines a pressure accumulation pool 111 of the container assembly, and the area surrounded by the container assembly accommodating the power generation equipment, the outlet wave height adjusting plate 107, the ocean current side guide plate 109 and the backflow guide plate 105 defines a second pressure accumulation pool 112 of the container assembly. The location of the containment assembly to house the power generation equipment, the area of inlet guide plate 102 and ocean current side guide plate 109 define a first pressure relief pool 114 of the containment assembly. In the first embodiment, the backflow guiding plate 105 further has at least one check valve 1051, which is opened when the water flow thrust is greater than a predetermined value (a first predetermined value), so as to allow the water flow WD from the pressure accumulation tank 111 to flow to the second pressure relief tank 112, thereby preventing the thrust plate 108 from being damaged by the excessive water flow thrust. In the case where the water flow thrust is not excessive (less than a certain value), the water flow WD of the accumulator 111 will flow to the thrust plate 108 of the power plant and then to the first relief reservoir 114. The water flow WD from the second pressure relief reservoir 112 may exit the container assembly via a water flow outlet F _ OUT, or may flow to a thrust plate 108 of the power generation plant, and then to the first pressure relief reservoir 114. The flow WD from the first reservoir 114 may partially converge with the flow WD from the flow inlet F _ IN, continue to the thrust plate 108 of the power plant, or exit the vessel assembly through the flow inlet F _ IN.

The power control room 103 of the power generation facility is constituted by a waterproof casing, and the generator 113 is provided in the power control room 103. A portion of the generator 113 is connected to the thrust plate traction mechanism 110, and a plurality of thrust plates 108 are connected to the thrust plate traction mechanism 110, wherein the power control room 103 is sealed in a waterproof manner to prevent water from flowing into the generator 113 because a portion of the generator 113 needs to be connected to the thrust plate traction mechanism 110. When the thrust plate 108 is pushed by the water flow WD, the thrust plate 108 drives the thrust plate traction mechanism 110 to rotate, thereby generating kinetic energy, so that the generator 113 converts the kinetic energy into electric energy.

In this embodiment, the number of thrust plates 108 is six, and are arranged in a symmetrical manner. In other embodiments, the number of thrust plates 108 may be three or more, and may even be asymmetrically arranged. The present invention is not limited by the manner and number of the thrust plates 108. In addition, the thrust plate 108 may further be pivotally connected to a damper (e.g., the damper 1081 shown in fig. 4), and when the thrust of the water flow is too large, the angle between the thrust plate 108 and the horizontal plane may be changed accordingly, so that part or all of the water flow passes directly without being resisted by the thrust plate 108.

IN the first embodiment, one end of the inlet guide plate 102 does not extend to one end of the inlet wave height adjustment plate 101, and one end of the sea current side guide plate 109 extends to one end of the inlet wave height adjustment plate 101, so that one end of the inlet wave height adjustment plate 101 and one end of the sea current side guide plate 109 are IN contact with each other, so that the water flow WD IN the first pressure relief tank 114 can partially converge with the water flow WD IN the water flow inlet F _ IN and continue to flow to the thrust plate 108 of the power generation facility, or flow out of the container assembly through the water flow inlet F _ IN. However, in other embodiments, the length of the inlet guide plate 102 may be adjusted, and the length of the ocean current side guide plate 109 may be adjusted accordingly.

Referring to fig. 2B, fig. 2B is a schematic top view of a tidal power generation device according to a second embodiment of the present invention. In the second embodiment of fig. 2B, the length of the inlet guide plate 102 'of the tidal power generation apparatus 1' is longer than the length of the inlet guide plate 102 of the tidal power generation apparatus 1, one end of the inlet guide plate 102 'extends and contacts the inlet wave height adjustment plate 101, and the length of the ocean current side guide plate 109' is shorter than the length of the ocean current side guide plate 109 of the tidal power generation apparatus 1, thereby forming another water outlet L _ OUT. Thus, the water flow WD of the first pressure-releasing tank 114 will directly flow OUT of the container assembly through the water outlet L _ OUT, and will not flow together with the water flow coming IN from the water inlet F _ IN, and will not flow OUT of the container assembly through the water inlet F _ IN, and will not interfere with the water flow coming IN from the water inlet F _ IN, so as to increase the power generation efficiency.

Referring to fig. 2C, fig. 2C is a schematic top view of a tidal power generation device according to a third embodiment of the present invention. In the third embodiment of fig. 2C, compared to the second embodiment, the length of the inlet guide plate 102 "of the tidal power generation device 1" is longer, and one end of the inlet guide plate 102 "protrudes OUT of the water outlet L _ OUT and the inlet wave height adjusting plate 101. IN the third embodiment, the inlet guide plate 102 ″ can prevent the water flowing OUT of the container assembly through the water outlet L _ OUT from interfering with the water flowing into the water inlet F _ IN, thereby increasing the power generation efficiency.

Referring to fig. 3, fig. 3 is a schematic view showing an angular disposition of an inlet guide plate of a tidal power generation apparatus according to a fourth embodiment of the present invention. In order to improve the power generation efficiency of the tidal power generation device, in the present invention, the angle θ between the normal NL (i.e. the lateral extension direction) of the water flow inlet and the inlet guide plate 102, and the angle θ 1 between the normal NL of the water flow inlet and the ocean current side guide plate 104' may be selectively designed such that the sum of the angles θ and θ 1 is between 60 degrees and 120 degrees (including 60 degrees and 120 degrees), wherein the angles θ and θ 1 may be between 15 degrees and 60 degrees (including 60 degrees and 120 degrees), and the power generation efficiency can be improved as long as the sum is between 60 degrees and 120 degrees. In addition, the angle between the current guiding plate 109' ″ and the normal NL to the water inlet is not limited.

Referring to fig. 4 to 6, fig. 4 is a schematic perspective view of a power generation device of a tidal power generation apparatus according to any one embodiment of the present invention, fig. 5 is a schematic perspective view of a thrust plate of the tidal power generation apparatus according to any one embodiment of the present invention, and fig. 6 is a schematic angle change view of the thrust plate of the tidal power generation apparatus according to any one embodiment of the present invention. One end of each of the thrust plates 108 of the power generation equipment is pivotally connected to a damper 1081 (in fig. 4 and 5, there are a plurality of dampers 1081), and the damper 1081 is, for example, a hydraulic damper, but not limited thereto. One end of the damper 1081 is locked to a portion of the thrust plate pulling mechanism 110 (as shown in fig. 4 and 5), so that when the thrust force of the thrust plate 108 is smaller than a specific value, the angle between the thrust plate 108 and the horizontal plane is 90 degrees, so as to receive the thrust force of the thrust plate, thereby driving the thrust plate pulling mechanism 110 to rotate (in this embodiment, the rotation direction is counterclockwise). When the thrust force of the water flow is greater than a specific value, the angle between the thrust plate 108 and the horizontal plane changes, and the change of the angle is related to the magnitude of the thrust force of the water flow, for example, in fig. 6, the angle between the thrust plate 108 and the horizontal plane changes from 90 degrees to almost 0 degrees (this angle is not used to limit the present invention).

Referring to fig. 7, fig. 7 is a schematic view showing the angle change of the thrust plate of the tidal power generation device in different positions according to any embodiment of the present invention. In fig. 7, the circular area formed by the six thrust plates 108 is divided into six areas R1 to R6 in the counterclockwise direction from the end corresponding to the entrance guide plate 102. The thrust force of the water flow in the regions R2-R6 is generally smaller than a specific value, so that the angle between the thrust plate 108 and the horizontal plane is mostly 90 degrees (as the thrust plate 108 shown in the left side of fig. 7) when the thrust plate 108 is in the regions R2-R6. The thrust force of the water flow in the region R1 is generally greater than a specific value, and the thrust force of the water flow decreases as it approaches the region R2, so that the angle between the thrust plate 108 and the horizontal plane increases gradually from almost 0 degrees in the region R1 from the approach region R6 to the approach region R2 (as the thrust plate 108 shown in the right side of fig. 7). In other words, each of the plurality of thrust plates 108 is pivotally connected to at least one damper 1081, so as to change the angle between the thrust plate 108 and a horizontal plane when the water thrust is greater than a second specific value. . In this way, through the use of the damper 1081, the tidal power generation device according to the embodiment of the present invention can more effectively prevent the thrust plate 108 from being damaged due to the excessive thrust of the water flow, and can maintain a certain power generation efficiency, without changing the angles between all the thrust plates 108 and the horizontal plane to almost 0 degree when the thrust of the water flow is excessive, so that the thrust plate traction mechanism 110 hardly rotates any more, thereby reducing the power generation efficiency.

Referring to fig. 8 to 10, fig. 8 is a perspective view of a tidal power generation device according to a fifth embodiment of the present invention, fig. 9 is a top view of the tidal power generation device according to the fifth embodiment of the present invention, and fig. 10 is a partial sectional view of the tidal power generation device according to the fifth embodiment of the present invention. In the fifth embodiment, the tidal power generation device 2 includes a container assembly (composed of a bottom plate (no reference numeral), two inlet wave height adjustment plates 201, two inlet guide plates 202, two ocean current side guide plates 204, a return guide plate 205, a return outlet gate plate 215, and a ramp-shaped ascending guide plate 216), and a power generation apparatus (composed of a power control room 203, a plurality of thrust plates 208, a plurality of dampers 2081, a thrust plate traction mechanism 210, and a power generator 213). The inlet wave height adjusting plate 201 is located on a first side of the container assembly, the two ocean current side guiding plates 204 are located on a second side and a third side of the container assembly respectively, the first side is adjacent to the second side and the third side, the backflow guiding plate 205 is located on a fourth side of the container assembly, and the backflow guiding plate is located between the two ocean current side guiding plates 204, and the first side is opposite to the fourth side. The power generation apparatus is housed in the container assembly, for example, disposed between the left and right sides of the container assembly.

The two inlet wave height adjusting plates 201, the two ocean current side guide plates 204, the backflow guide plate 205, the backflow outlet gate plate 215 and the bottom plate substantially form a container which is gradually reduced from the right side to the left side, and the two inlet guide plates 202 and the ascending guide plate 216 are arranged in the container, so that the container assembly is formed. Two inlet wave height adjustment plates 201 are located on the right side of the container assembly and are connected to each other. The inlet wave height adjustment plate 201 is vertically movable to adjust the inflow of the water flow WD at the water flow inlet F _ IN and to limit the flow of excessively high waves from entering the reservoir assembly. The two ocean current side lead plates 204 are obliquely arranged, wherein one end of each of the two ocean current side lead plates 204 corresponds to one end of each of the two inlet guide plates 202, the other end of one end of each of the two ocean current side lead plates 204 extends towards the power generation equipment, and the other end of one of the ocean current side lead plates 204 is connected with the backflow guide plate 205. Briefly, as shown in fig. 9, one of the ocean current side guiding plates 204 extends from the lower right to the upper left from one end of the inlet wave height adjusting plate 201 on the lower right, and the other end of the ocean current side guiding plate 204 is in floating connection; and the other current side guide plate 204 extends from the upper right to the lower left from one end of the inlet wave height adjusting plate 201 on the upper right, and the other end of the current side guide plate 204 is connected with the backflow guide plate 205.

As shown in fig. 9, two inlet guide plates 202 are diagonally disposed in the container assembly. One end of one inlet guide plate 202 is connected to the joint of the two inlet wave height adjusting plates 201 and extends upwards from the joint to the left to be connected to one of the ocean current side guide plates 204; one end of the other inlet guide plate 202 is connected to the joint of the two inlet wave height adjusting plates 201, and extends downwards from the joint to the left to be connected to the other ocean current side guide plate 204. Both inlet guide plates 202 have one-way valves (not numbered) disposed thereon to slow the thrust of the water flow when the thrust of the water flow is excessive and to prevent the water flow with too little thrust from passing through the inlet guide plates 202. As shown in fig. 9, the lifting guide plate 216 is disposed between the power generation equipment and the two inlet guide plates 202, and is used to reduce the water flow thrust of the water flow passing through the inlet guide plates 202, so as to prevent the thrust plate 208 of the power generation equipment from being damaged by the excessive water flow thrust. In other words, each of the two inlet guide plates 202 has at least one check valve, so that when the water flow thrust is greater than a third specific value, the water flow WD flows to the plurality of thrust plates 208 through the check valve. As shown in fig. 10, the rising guide plate 216 has a ramp shape, so that the water flow thrust can be reduced.

As shown in fig. 8-10, the backflow guide plate 205 has an arc shape to guide the water flow passing through the power generation equipment from the ascending guide plate 216 to continue to the thrust plate 208 of the power generation equipment. Two ends of the backflow guide plate 205 are respectively connected with one of the seawater side guide plates 204 and the backflow outlet gate plate 215, and the backflow outlet gate plate 215 is also connected with the other seawater side guide plate 204. One side of the return exit restrictor panel 215 defines a water exit F _ OUT, and the other side of the return exit restrictor panel 215, the other of the ocean side draft plates 204, and the location of the container assembly housing the power generation equipment define a pressure relief reservoir 212. When the water flow thrust of the pressure relief tank 212 is greater than a specific value, the one-way valve 2151 provided on the return outlet restrictor 215 is opened, so that the water flow thrust of the pressure relief tank 212 is not too large. In other words, the return outlet gate 215 has at least one-way valve 2151 for allowing the water flow WD to flow OUT of a water flow outlet F _ OUT of the container assembly when the water flow thrust is greater than a fourth specified value. Referring to fig. 10 in particular, it is noted that the height of the container assembly at the position for accommodating the power generating equipment is greater than the height of the pressure relief pool 212 (e.g., the height difference H in fig. 10), so that the thrust plate 208 can be more easily pushed by the water flow guided by the backflow guide plate 205.

Specifically, the container assembly of the tidal power generation device can effectively guide the direction of water flow through the design of the inlet guide plate and the backflow guide plate, and has the effect of buffering the thrust of excessive water flow, so that the technical problem of avoiding the thrust plate of the power generation equipment from being damaged is solved. In addition, in other embodiments, in order to further improve the power generation efficiency and avoid the probability of damage to the thrust plate, at least one of the following technical features may be selectively used: the backflow guide plate is further provided with a one-way valve; the container assembly is provided with more than two water inflow inlets and an inlet guide plate, and the inlet guide plate is provided with a one-way valve; a lifting guide plate is arranged in the area of the water flow inlet before reaching a thrust plate of the power generation equipment; and the damper is pivoted with the thrust plate so as to change the angle between the thrust plate and the horizontal plane according to the water flow resistance.
