Next, other embodiments are used to illustrate more details of this creation. Please refer to Figures 1 and 2A. Figure 1 is a three-dimensional schematic diagram of the tidal power generation device according to the first embodiment of the creation, and Figure 2A is a top schematic diagram of the tidal power generation device according to the first embodiment of the creation. The tidal power generation device 1 includes a container assembly (from the bottom plate (not marked with component symbols), the inlet wave height adjustment plate 101, the inlet guide plate 102, the ocean current side guide plates 104, 109, the return guide plate 105, the return side guide plate 106, 115 and exit wave height adjustment board 107) and power generation equipment (consisting of a power control room 103, a plurality of thrust plates 108, a thrust plate traction mechanism 110, and a generator 113). The power generation equipment is accommodated in the container assembly, for example, is arranged between the left and right sides of the container assembly, and the power generation equipment can further have a frame (not marked with component symbols, such as the square frame in the first figure), which is locked or locked by the frame It is fixed to the container assembly to fix the container assembly and the power generation equipment.

The inlet wave height adjustment plate 101, the current side guide plates 104, 109, the outlet wave height adjustment plate 107 and the bottom plate roughly constitute a rectangular container, and the container is equipped with an inlet guide plate 102, a return guide plate 105 and a return side The lead plates 106 and 115 constitute a container assembly thereby. The inlet wave height adjustment plate 101 is located on the right side (first side) of the container assembly, and it can move vertically to adjust the water inflow of the water flow WD at the water inlet F_IN, and limit the excessively high wave water flow from entering the container assembly. The sea current side guide plates 104 and 109 are located on the upper (second side) and lower (third side) sides of the container assembly, and connect the inlet wave height adjustment plate 101 and the outlet wave height adjustment plate 107. The outlet wave height adjustment plate 107 is located on the left side (fourth side) of the container assembly, which can move vertically to adjust the water output of the water flow WD at the water outlet F_OUT and restrict the excessively high wave water flow WD from entering and exiting the container assembly. The outlet wave height adjustment plate 107 and the water outlet F_OUT can be non-essential components of this creation, and they can be replaced by a fixed ocean current side guide plate, or directly replaced by a return guide plate 105. At this time, the return guide plate 105 is also Located on the left side (fourth side) of the container assembly.

The inlet guide plate 102 is arranged obliquely, and has an angle with the lateral extension direction of the container assembly (ie, the normal line of the water inlet F_IN), and is arranged at the position where the container assembly accommodates the power generation equipment and the inlet wave height adjustment plate 101 Between the sea 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 return guide plate 105 is arranged obliquely, and has an included angle with the lateral extension direction of the container assembly, and is arranged between the position where the container assembly accommodates the power generation equipment and the outlet wave height adjustment plate 107, and is arranged on the current side guide plate Between 104 and 109, the water flow WD pushing the thrust plate 108 is guided to the thrust plate 108 of the power generation equipment again. The return side guide plate 115 is arranged obliquely, and has an angle with the lateral extension direction of the container assembly, and is connected between the return flow guide plate 105 and the ocean current side guide plate 104, so that the water flow WD can more easily flow to the thrust plate of the power generation equipment 108. The return side guide plate 106 is arranged obliquely, and has an angle with the lateral extension direction of the container assembly, and is connected between the return flow guide plate 105 and the ocean current side guide plate 109, so that the water flow WD can more easily flow to the thrust plate of the power generation equipment 108. The return side guide plates 115 and 106 may be unnecessary components in this creation, but can be removed.

The location of the container assembly to accommodate the power generation equipment, the area surrounded by the outlet wave height adjustment plate 107, the current side guide plate 104 and the return guide plate 105 define the pressure storage tank 111 of the container assembly, and the position of the container assembly to accommodate the power generation equipment The area surrounded by the outlet wave height adjustment plate 107, the current side guide plate 109 and the return flow guide plate 105 defines the second pressure relief pool 112 of the container assembly. The position where the container assembly accommodates the power generation equipment, the area of the inlet guide plate 102 and the sea current side guide plate 109 define the first pressure relief pool 114 of the container assembly. In the first embodiment, the return guide plate 105 is further provided with at least one one-way valve 1051 to be opened when the water flow thrust is greater than a specific value (first specific value), so that the water flow WD in the accumulator 111 flows to the second The pressure relief tank 112 prevents the thrust plate 108 from being damaged by the excessive water current thrust. When the water flow thrust is not too large (less than a specific value), the water flow WD in the pressure storage tank 111 will flow to the thrust plate 108 of the power generation equipment, and then flow to the first pressure relief tank 114. The water flow WD of the second pressure relief tank 112 may flow out of the container assembly through the water outlet F_OUT, or may flow to the thrust plate 108 of the power generation equipment, and then flow to the first pressure relief tank 114. The water flow WD of the first pressure relief tank 114 may partially converge with the water flow WD of the water flow inlet F_IN and continue to flow to the thrust plate 108 of the power generation equipment, or flow out of the container assembly through the water flow inlet F_IN.

The power control room 103 of the power generation equipment is constituted by a waterproof housing, and the generator 113 is installed in the power control room 103. A part of the generator 113 will be connected to the thrust plate traction mechanism 110, and a plurality of thrust plates 108 will be connected to the thrust plate traction mechanism 110, in which the power control room 103 will be waterproof and sealed to avoid being part of the generator 113 It needs to be connected to the thrust plate traction mechanism 110, which causes water to flow into the generator 113. 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 electrical energy.

In this embodiment, the number of thrust plates 108 is six, and they are arranged in a symmetrical manner. In other embodiments, the number of thrust plates 108 may also be three or more, and may even be asymmetrically arranged. This creation is not limited by the setting method and number of thrust plates 108. In addition, the thrust plate 108 can be pivotally connected to a damper (for example, the damper 1081 in Figure 4). When the thrust of the water flow is too large, the thrust plate 108 can change the angle between it and the horizontal plane to allow part or all of the water flow. Pass 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 ocean current side guide plate 109 extends to one end of the inlet wave height adjustment plate 101, so that the inlet wave One end of the height adjustment plate 101 and one end of the current guide plate 109 are in contact with each other, so the water flow WD of the first pressure relief tank 114 can partially converge with the water flow WD of the water inlet F_IN, and continue to flow to the thrust plate 108 of the power generation equipment, or pass through The water inlet F_IN flows out of the container assembly. However, in other embodiments, the length of the inlet guide plate 102 can be adjusted, and the length of the ocean current side guide plate 109 can also be adjusted accordingly.

Please refer to Figure 2B. Figure 2B is a schematic top view of the tidal power generation device according to the second embodiment of the present creation. In the second embodiment in Figure 2B, the length of the entrance guide plate 102' of the tidal power generation device 1'is longer than the length of the entrance guide plate 102 of the tidal power generation device 1, and one end of the entrance guide plate 102' extends It 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 device 1, thereby forming another water outlet L_OUT. In this way, the water flow WD of the first pressure relief tank 114 will directly flow out of the container assembly through the water outlet L_OUT, and will not merge with the water flow coming in from the water inlet F_IN, nor will it flow out of the container assembly through the water inlet F_IN. Disturb the incoming water flow at the water inlet F_IN to increase the power generation efficiency.

Furthermore, please refer to Figure 2C. Figure 2C is a schematic top view of the tidal power generation device according to the third embodiment of the present creation. In the third embodiment in Figure 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 To the outside of the water flow outlet L_OUT and the inlet wave height adjustment 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, so as to increase the power generation efficiency.

Please refer to FIG. 3, which is a schematic diagram of the angle configuration of the entrance guide plate of the tidal power generation device according to the fourth embodiment of the present creation. In order to make the power generation efficiency of the tidal power generation device better, in this creation, the angle θ between the normal line NL of the water inlet (that is, the lateral extension direction) and the inlet guide plate 102 can be selectively designed, and optionally The angle θ 1 between the normal NL of the water inlet and the current side guide plate 104' is designed so that the sum of the angle θ and θ 1 is between 60 degrees and 120 degrees (including 60 degrees and 120 degrees), where the angle θ and θ 1 can be between 15 degrees and 60 degrees (including 60 degrees and 120 degrees). As long as the sum is between 60 degrees and 120 degrees, the power generation efficiency can be better. In addition, there is no need to limit the angle between the ocean current side guide plate 109''' and the normal line NL of the water inlet.

Please refer to Figures 4 to 6. Figure 4 is a three-dimensional schematic diagram of the power generation equipment of the tidal power generation device according to any embodiment of this creation, and Figure 5 is the thrust plate of the tidal power generation device according to any embodiment of this creation The three-dimensional schematic body and Fig. 6 are schematic diagrams of the angle change of the thrust plate of the tidal power generation device according to any embodiment of the invention. One end of each of the thrust plates 108 of the power generation equipment is pivotally connected to a damper 1081 (in Figures 4 and 5, there are multiple dampers 1081), and the dampers 1081 are, for example, hydraulic dampers, but not so As a limit. One end of the damper 1081 is locked to a part of the thrust plate traction mechanism 110 (as shown in Figures 4 and 5), so that when the thrust of the thrust plate 108 is less than a specific value, the angle between the thrust plate 108 and the horizontal plane is 90 degrees , In order to receive the thrust of the water flow to drive the thrust plate traction mechanism 110 to rotate (in this embodiment, the direction of rotation is counterclockwise). When the water current thrust is greater than a certain value, the angle between the thrust plate 108 and the horizontal plane will change, and the angle change will be related to the magnitude of the water current thrust. For example, in Figure 6, the angle between the thrust plate 108 and the horizontal plane changes from 90 The degree becomes almost 0 degree (this angle is not used to limit this creation).

Please refer to Fig. 7, which is a schematic diagram of the angle change of the thrust plate of the tidal power generation device in any embodiment of the present creation at different positions. In Figure 7, the circular area formed by the six thrust plates 108 is sequentially divided into six areas R1 to R6 from the end corresponding to the entrance guide plate 102 in a counterclockwise direction. The water current thrust in the regions R2 to R6 is generally less than a specific value, so when the thrust plate 108 is in the regions R2 to R6, the angle between the thrust plate 108 and the horizontal plane is mostly 90 degrees (such as the thrust plate 108 shown on the left in Figure 7). The water current thrust of the area R1 is generally greater than a certain value, and the closer the water current thrust is to the area R2, the smaller it will be. Therefore, the thrust plate 108 is in the area R1, from the direction closer to the area R6 to the direction closer to the area R2, and the thrust plate 108 is in contact with the horizontal plane. The angle between them will gradually increase from almost 0 degrees (as shown in the thrust plate 108 on the right side of Figure 7). In other words, each of the 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 flow thrust is greater than a second specific value. . In this way, through the use of the damper 1081, the tidal power generation device of this creative embodiment can more effectively prevent the thrust plate 108 from being damaged due to excessive water current thrust, and can maintain a certain power generation efficiency, instead of when the water current thrust is too large, The angle between all the thrust plates 108 and the horizontal plane is changed to almost 0 degrees, so that the thrust plate traction mechanism 110 hardly rotates, and the power generation efficiency is reduced.

Please refer to Figures 8 to 10. Figure 8 is a three-dimensional schematic diagram of the tidal power generation device according to the fifth embodiment of the creation, Figure 9 is a schematic top view of the tidal power generation device according to the fifth embodiment of the creation, and Figure 10 It is a partial cross-sectional schematic diagram of the tidal power generation device of the fifth embodiment of the present creation. In the fifth embodiment, the tidal power generation device 2 includes a container assembly (consisting of a bottom plate (component symbols not marked), two inlet wave height adjustment plates 201, two inlet guide plates 202, two ocean current side guide plates 204, and return The guide plate 205, the return exit gate plate 215, and the ramp-shaped ascending guide plate 216 constitute) and power generation equipment (consisting of the power control room 203, a plurality of thrust plates 208, a plurality of dampers 2081, and a thrust plate traction mechanism 210 and The generator 213 constitutes). The inlet wave height adjustment plate 201 is located on the first side of the container assembly, and the two current-side guide plates 204 are respectively located on the second side and the third side of the container assembly, and the first side is adjacent to the second side and the third side, The backflow guide plate 205 is located on the fourth side of the container assembly and between the two current side guide plates 204, the first side facing the fourth side. The power generation equipment is contained in the container assembly, for example, between the left (fourth side) and the right (first side) sides of the container assembly.

The two inlet wave height adjustment plates 201, the two current side guide plates 204, the return flow guide plate 205, the return flow outlet gate plate 215 and the bottom plate roughly constitute a container that tapers from the right to the left, and two are arranged in the container. The inlet guide plate 202 and the rising guide plate 216 constitute a container assembly thereby. Two inlet wave height adjustment plates 201 are located on the right side of the container assembly and connected to each other. The inlet wave height adjustment plate 201 can be moved vertically to adjust the water inflow of the water flow WD at the water flow inlet F_IN, and limit the excessively high wave water flow from entering the container assembly. Two ocean current side guide plates 204 are arranged obliquely. One end of each of the two ocean current side guide plates 204 corresponds to one end of each of the two inlet guide plates 202. One end and the other end extend toward the power generation equipment, and the other end of one of the current-side guide plates 204 is connected to the return guide plate 205. To put it simply, as shown in Figure 9, one of the current side guide plates 204 extends from one end of the inlet wave height adjustment plate 201 on the lower right side from lower right to upper left, and the other end of the current side guide plate 204 is floating; And the other current side guide plate 204 extends from one end of the inlet wave height adjustment plate 201 on the upper right side from upper right to lower left, and the other end of the current side guide plate 204 is connected to the return guide plate 205.

As shown in Figure 9, two inlet guide plates 202 are diagonally installed in the container assembly. One end of the inlet guide plate 202 is connected to the junction of the two inlet wave height adjustment plates 201, and extends from the junction to the upper left to connect to one of the current side guide plates 204; the other inlet guide plate 202 One end of is connected to the junction of the two inlet wave height adjustment plates 201, and extends from this junction to the lower left to be connected to the other current side guide plate 204. Both inlet guide plates 202 are provided with one-way valves (not marked with component symbols) on them to slow down the water flow thrust when the water flow thrust is too large, and prevent the water flow from passing through the inlet guide plate 202 when the water flow thrust is too small. As shown in Figure 9, the rising guide plate 216 is arranged between the power generation equipment and the positions of the two inlet guide plates 202, which is used to reduce the water flow thrust of the water passing through the inlet guide plate 202 to avoid excessive water flow thrust The thrust plate 208 of the power generation equipment will be damaged. In other words, each of the two inlet guide plates 202 has at least one one-way valve, so that when the water flow thrust is greater than a third specific value, the water flow WD flows to the thrust plates 208 through the one-way valve. As shown in Fig. 10, the ascending guide plate 216 has a ramp shape, so the water flow thrust can be reduced.

As shown in Figs. 8 to 10, the return guide plate 205 has an arc shape to guide the water flow from the ascending guide plate 216 through the power generation equipment to continue to flow to the thrust plate 208 of the power generation equipment. Two ends of the return flow guide plate 205 are respectively connected to one of the ocean current side guide plates 204 and the return flow outlet gate plate 215, and the return flow outlet gate plate 215 is also connected to the other of the ocean current side guide plates 204. One side of the backflow outlet gate plate 215 is defined as the water flow outlet F_OUT, and the other side of the backflow outlet gate plate 215, the position where the other current-side guide plate 204 and the container assembly accommodate the power generation equipment defines the pressure relief tank 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 backflow outlet gate plate 215 will be opened, so that the water flow thrust of the pressure relief tank 212 will not be too large. In other words, the backflow outlet gate plate 215 has at least one one-way valve 2151 to allow the water flow WD to flow out of the water outlet F_OUT of the container assembly when the water flow thrust is greater than a fourth specific value. Please refer to Figure 10 in particular. Please note that the height of the position where the container assembly houses the power generation equipment will be greater than the height of the pressure relief tank 212 (such as the height difference H in Figure 10) to allow the return guide plate 205 to guide The flow of water makes it easier to push the thrust plate 208.
