Technical Field
[0001] The present invention belongs to the field of ocean power generation, and in particular relates to a shore-based ocean surge power generation device. Background Art
[0002] More and more new energy sources are being used for power generation both at home and abroad. Among these new energy sources, ocean energy is widely distributed and can be used sustainably, making it worthy of vigorous development. However, at present, there are still many imperfections in the devices and equipment used to generate electricity using ocean energy, so they cannot be widely promoted. In particular, my country has a vast coastline, but there are no shore-based power generation devices that can efficiently utilize large ocean waves. Large amounts of tidal water not only severely scour the embankments, reducing their service life, but also resulting in energy waste. Therefore, it is necessary to develop a power generation device that can efficiently utilize ocean wave energy in order to improve the efficiency and universal applicability of ocean energy utilization. Summary of the Invention
[0003] The object of the present invention is to provide a shore-based ocean surge power generation device, which realizes the purpose of efficiently utilizing ocean energy by successively utilizing the kinetic energy of surge waves and the potential energy of water at ebb tide.
[0004] The technical solution for achieving the objectives of the present invention is as follows: a shore-based ocean surge power generation device, comprising a housing in the form of a shell, the housing being fixedly mounted on a dam via a fixing plate, the interior of the housing being divided into a first chamber and a second chamber connected at the upper portion by a partition, the lower portion of the first chamber being provided with a surge inlet in the shape of a crab claw, parallel to and above the horizontal plane, and the first chamber being provided with a plurality of first water wheels along the side wall of the housing;
[0005] The upper end of the partition is bent in an arc toward the dam, and a third water wheel is provided in the arc-shaped bend of the partition, which is located in the second chamber. A plurality of downwardly inclined baffles are provided on one side of the partition located in the second chamber, and a return hole is provided at a position on the partition that matches each baffle. A second water wheel is provided between the partition and the baffle, and the second water wheel is located below the corresponding return hole; a return pipe is provided at the lower part of the second chamber, and a fourth water wheel is provided in the return pipe, and the lower end of the return pipe is inserted into the horizontal plane;
[0006] All water wheels are equipped with generators. During surges, seawater flows into the first chamber from the surge inlet, driving the first water wheel to rotate and complete the first power generation. The part of the seawater that passes over the baffle drives the third water wheel to rotate and complete the second power generation. The seawater that does not pass over the baffle flows into the second chamber through the return hole, driving the second water wheel to rotate and complete the third power generation. The seawater entering the second chamber will pass through the fourth water wheel and complete the fourth power generation.
[0007] Furthermore, the body and the fixing plate are both made of polymer materials with anti-corrosion coating on the surface, and the angle between the body and the fixing plate is an obtuse angle; during installation, the body and the embankment slope are set tightly, and the fixing plate is fixed to the embankment by bolts.
[0008] Furthermore, a dam protection layer is provided on the dam, and the surge power generation device is installed on the dam protection layer.
[0009] Furthermore, a plurality of slots are provided on the side wall of the first chamber, the first water wheels are arranged in the slots, and the plurality of first water wheels are arranged in an exponential function image array.
[0010] Furthermore, the reflux hole is a through hole with a square cross-section and an inclined arrangement. A guide plate that cooperates with the reflux hole is provided on the side of the partition facing the first chamber. The upper end of the guide plate is triangular, the upper end of the triangle is higher than the opening of the reflux hole, and the bottom of the triangle is flush with the side of the upper opening of the reflux hole. The guide plate prevents the surging seawater from falling into the reflux hole when it washes upward on the partition, and the seawater falls into the reflux hole when it flows downward along the partition.
[0011] Furthermore, a waterproof box is provided in the second chamber near the return pipe, and a planetary reducer and a return generator are provided in the waterproof box. The fourth water wheel is connected to the planetary reducer through a transmission shaft.
[0012] Furthermore, an arc-shaped wave-breaking plate with an opening toward one side of the dam is provided at the bottom of the return pipe to prevent seawater from entering the return pipe during surges, and the height of the fourth water wheel is set higher than the horizontal plane.
[0013] Furthermore, the first water wheel, the second water wheel and the third water wheel are all equipped with a reducer and a generator arranged outside the body.
[0014] Furthermore, the reducer and generator of each water wheel located outside the body are protected by a cover, and a V-shaped wave-breaking board (120) is also provided on this side of the body, and all the covers are located inside the wave-breaking board (120).
[0015] A method for generating electricity using the surge power generation device described above comprises the following steps:
[0016] The fixing plate and the machine body are fixedly installed close to the dam, and the first chamber is made higher than the horizontal plane, and the lower end of the return pipe is inserted into the horizontal plane;
[0017] The surge rushes into the first chamber through the surge inlet, and the multiple first water wheels are arranged in an exponential function pattern, which can effectively absorb the kinetic energy of the surge and convert it into rotational mechanical energy, which is then converted into electrical energy through the corresponding reducer and generator, realizing the first power generation utilization of a single tidal wave;
[0018] The surge wave washes against the baffle due to its potential energy and continues to move upward along the baffle. The water in a surge wave that passes over the top of the baffle bend enters the second chamber and washes the third water wheel. The third water wheel rotates under the action of the flowing water, and then is converted into electrical energy through the corresponding reducer and generator, realizing the second power generation utilization of the single tidal wave.
[0019] The water that does not pass over the top of the baffle bend in a wave flows downward along the baffle due to gravity. The downward-flowing seawater enters the second chamber through the recirculation hole and drives the second water wheel to rotate. The water is then converted into electrical energy through the corresponding reducer and generator, realizing the third power generation utilization of the single tidal wave.
[0020] The seawater entering the second chamber passes through the fourth water wheel, which rotates under the action of the water flow and is then converted into electrical energy through the corresponding planetary reducer and return generator, realizing the fourth power generation utilization of a single tidal wave.
[0021] Compared with the prior art, the present invention has the following significant advantages:
[0022] (1) The present invention is installed close to the dam. When the device is installed close to the dam, during a surge, when the surge comes up, the seawater will drive the first water wheel to rotate and complete the first power generation operation. The part of the seawater that passes over the baffle will drive the third water wheel to rotate and complete the second power generation operation. The part of the seawater that does not pass over the baffle will flow into the second chamber through the return hole and drive the second water wheel to rotate and complete the third power generation operation. The seawater entering the second chamber will uniformly pass through the fourth water wheel to rotate and complete the fourth power generation operation. Therefore, the present invention can complete four power generation operations under the impact of one surge, effectively improving the conversion rate and utilization rate of river tide power generation, thereby increasing the power generation.
[0023] (2) Since the device is installed close to the dam, it is equivalent to a protective layer for the dam. Therefore, in addition to generating electricity, it can also effectively reduce the erosion of the dam by the tide, increase the time interval between two maintenance of the dam, and thus increase safety. The device can pour the tidal water with strong impact force during high tide into the first chamber, effectively preventing the tide from rushing onto the dam and eroding the river bank of the dam.
[0024] (3) The first water wheel of the present invention is arranged in an exponential function image, which can make full use of the surge and increase the power generation per unit time. The partition is provided with a return hole, which can allow the surge that does not enter the second chamber to enter the second chamber through the return hole and then drive the fourth water wheel to perform power generation operation, thereby greatly improving the power generation effect.

The body 101 is crab-claw-shaped and its opening is facing the ocean. The body 101 and the fixing plate 102 are installed close to the dam. The fixing plate 102 is fixed to the dam by a number of bolts. The body 101 is connected to the dam by a partition. The plate 105 is divided into a first chamber 103 and a second chamber 104. The upper ends of the first chamber 103 and the second chamber 104 are connected. The lower end of the first chamber 103 is a surge inlet 1031. A plurality of slots 112 are provided on the upper side of the interior of the first chamber 103. A first water wheel 113 is installed in each slot 112. A corresponding reducer and generator are installed on one side of each first water wheel 113. The reducer and generator are arranged on the outside of the body 101. A plurality of first covers 121 are fixedly installed on the outside of the body 101. Each first cover 121 is buckled onto the corresponding reducer and generator.
[0037] A third water wheel 118 is installed in the second chamber 104. The third water wheel 118 is located below the bend on the upper side of the partition 105. A corresponding reducer and generator are installed on one side of the third water wheel 118. The reducer and generator are arranged on the outside of the body 101. A third cover 122 is fixedly installed on the outside of the body 101. The third cover 122 is buckled on the corresponding reducer and generator. The number of guide plates 117 is the same as the number of return holes 116, the number of baffles 114, and the number of second water wheels 115.
[0038] Two second water wheels 115 are installed in the second chamber 104, and a corresponding reducer and generator are installed on one side of each second water wheel 115. The reducer and generator are arranged on the outside of the body 101. A number of second covers 123 are fixedly installed on the outside of the body 101, and each second cover 123 is buckled on the corresponding reducer and generator. A number of reflux holes 116 are opened on the partition 105, and a number of guide plates 117 are also fixedly installed on the partition 105. Each guide plate 117 is arranged one by one with the corresponding reflux hole 116. A number of baffles 114 are fixedly installed on the lower side of the partition 105. The two second water wheels 115 are arranged linearly according to the water launch direction of the second chamber 104. Each second water wheel 115 is located between the corresponding baffle 114 and the partition 105, and each second water wheel 115 is located below the corresponding reflux hole 116.
[0039] The reducers and generators for the first water wheel 113, the second water wheel 115 and the third water wheel 118 for generating electricity are all installed on one side of the body 101. The planetary reducer 110 and the generator for generating electricity of the fourth water wheel 109 are installed in the waterproof box 106. The waterproof box 106 is fixed in the second chamber 104. The waterproof box 106 is installed in the second chamber 104. The return generator 111 and the planetary reducer 110 are fixed in the waterproof box 106. The return generator 111 is connected to the rotating shaft 108 through the planetary reducer 110. The fourth water wheel 109 is installed on the rotating shaft 108. A return pipe 107 is installed on the body 101. The return pipe 107 is connected to the second chamber 104. The fourth water wheel 109 is located in the return pipe 107.
[0040] A wavebreak 120 is fixedly installed on one side of the body 101. The first cover 121, the second cover 123 and the third cover 122 are all located inside the wavebreak 120. The partition 105 is arranged at an angle, and the upper end of the partition 105 is bent toward the second chamber 104. In this embodiment, the bend is an arc shape.
[0041] By adopting the above technical solution: the surge inlet 1031 is a crab claw-shaped opening, and the surge inlet 1031 is parallel to the horizontal plane, which can allow more surges to rush into the first chamber 103, and the return hole 116 is a square hole arranged obliquely. The wave breaking plate 120 can effectively block the surges, thereby preventing the surges from eroding the first cover body 121, the second cover body 123 and the third cover body 122, thereby increasing the safety of the cover body. The lower end of the return pipe 107 is equipped with a wave blocking plate 1071, which can effectively prevent the surges from rushing into the return pipe 107, and the first water wheel 113 is arranged in an exponential function image array ( Figure 5 The dotted line in the figure is the array direction of the first water wheel 113, which is specifically an image of the exponential function y=2x where -2<x<-1. This allows the surge to be fully utilized, thereby increasing the amount of power generated per unit time. The partition 105 is provided with a return hole 116, which allows the surge that does not enter the second chamber 104 to enter the second chamber 104 through the return hole 116, and then drive the fourth water wheel 109 to generate electricity, thereby significantly improving the power generation effect. Figure 7 and Figure 8As shown, when in use, the surge rushes into the first chamber 103 through the surge inlet 1031, and the multiple first water wheels 113 are arranged in an exponential function pattern, which can effectively absorb the kinetic energy of the surge and convert it into rotational mechanical energy, and then convert it into electrical energy through the corresponding reducer and generator, thereby realizing the first power generation utilization of a single tidal wave; the surge washes on the partition 105 due to the potential energy and continues to move upward along the partition 105. The water that passes over the top of the bend of the partition 105 in a surge will enter the second chamber 104 and wash the third water wheel 118. The third water wheel 118 rotates under the action of the flowing water, and then is converted into electrical energy through the corresponding reducer and generator, thereby realizing the second power generation utilization of a single tidal wave; a surge that does not pass over the partition 1 The water at the top of the 05 bend will flow downward along the partition 105 due to gravity (the guide plate 117 is inclined to the partition 105 and cooperates with the corresponding return hole 116 to prevent seawater from falling into the return hole 116 when it washes upward on the partition 105). At this time, the downward-flowing seawater will enter the second chamber 104 through the return hole 116 and drive the second water wheel 115 to rotate, and then be converted into electrical energy through the corresponding reducer and generator, thereby realizing the third power generation utilization of a single tidal wave; the seawater entering the second chamber 104 will pass through the fourth water wheel 109, which will rotate under the action of the water flow, and then be converted into electrical energy through the corresponding planetary reducer 110 and the return flow generator 111, thereby realizing the fourth power generation utilization of a single tidal wave.
[0042] It should be noted that the patent of the present invention is a shore-based ocean surge power generation device. When in use, first, the fixing plate 102 and the body 101 are fixedly installed close to the embankment, and the first chamber 103 is higher than the horizontal plane, and the lower end of the return pipe 107 is inserted into the horizontal plane. In a wave, when the wave surges up, the seawater will drive the first water wheel 113 to rotate and complete the first power generation operation. The part of the seawater that passes over the partition 105 will drive the third water wheel 118 to rotate and complete the second power generation operation. The part of the seawater that does not pass over the partition 105 will flow into the second chamber 104 through the return hole 116 and drive the second water wheel 115 to rotate and complete the third power generation operation, entering the third power generation operation. The seawater in the second chamber 104 will pass through the fourth water wheel 109 and complete the fourth power generation operation. Therefore, the patent of the present invention can complete four power generation operations under the scouring of one surge wave, effectively improving the conversion rate and utilization rate of river tide power generation, thereby increasing the power generation amount; since the device is installed close to the dam, it is equivalent to a protective layer for the dam, so in addition to generating electricity, it can also effectively reduce the scouring of the dam by the tide, increase the time interval between two maintenance of the dam, and thereby increase safety. The device can pour the tide with strong impact force at high tide into the first chamber 103, effectively preventing the tide from rushing onto the dam and scouring the river bank of the dam.
