Technical Field

[0001] The present invention belongs to the technical field of wave energy power generation, and particularly relates to a floating single-direction rotation generator based on sensing wave swaying. Background Art

[0002] Wave energy, as an important part of ocean energy, is gradually becoming one of the important ways to solve the global energy crisis and environmental pollution problems due to its unique advantages such as high energy density, wide distribution, renewable nature, and environmental friendliness. Wave energy power generation, as an important branch of clean energy, not only conforms to the international energy transformation trend but also is an important part of the national energy strategy.

[0003] Improving the conversion efficiency of wave energy and reducing costs are one of the key points in current technical research. The energy distribution of waves is uneven, and how to maximize the capture and conversion of wave energy and reduce costs is the key challenge of the technology. Summary of the Invention

[0004] The object of the present invention is to address the problem of low conversion efficiency of wave energy in existing offshore power generation equipment. The present invention proposes a floating single-direction rotation generator based on sensing wave swaying. The wave motion causes the power generation device to sway left and right, and the mechanical energy during the swaying process is converted into electrical energy. By adjusting the swaying direction of the wave power generation device to be the same as the wave motion direction, the power generation power is maximized. A single-direction rotation gear device is adopted to make the generator rotate in one direction, improving the power generation efficiency. An anti-overturning device is adopted. In extreme cases, after the power generation mechanism overturns in the swaying direction, it can still generate power normally. After overturning laterally, it will automatically return to the power generation posture under the action of the eccentric slider, realizing normal power generation in most cases.

[0005] Specifically, the present invention provides a floating single-direction rotation generator based on sensing wave swaying, including a power generation device housing.

A swaying device is provided inside the power generation device housing. The swaying device includes a top connecting rod fixedly provided at the center of the power generation device housing. A rotating wheel is sleeved on the top connecting rod. One side of the rotating wheel is fixedly connected to a swinging rod. The other end of the swinging rod is fixedly connected to a pendulum. A single-direction rotation gear device is provided at the bottom end of the pendulum. The single-direction rotation gear device includes a generator connected to the pendulum. One end of the generator is rotatably connected to a generator rotating gear. A secondary moving gear and a second driving gear are respectively meshed on both sides of the generator rotating gear. A first driving gear is provided on one side of the secondary moving gear. The first driving gear is disposed opposite to the generator rotating gear and meshes with the secondary moving gear.

[0006] Preferably, a circular track device is circumferentially arranged inside the housing of the power generation device and meshes with the one-way rotating gear device.

[0007] Preferably, the circular track device includes a circular track beam, and a plurality of racks are equidistantly arranged on the circular track beam.

[0008] Preferably, a swinging hammer lateral constraint device is arranged between the pendulum and the housing of the power generation device. The swinging hammer lateral constraint device includes a lateral connecting rod fixedly connected to the pendulum at one end, and a roller is arranged at the other end of the lateral connecting rod. A lateral track matching the roller is circumferentially arranged inside the housing of the power generation device.

[0009] Preferably, the sliding assembly includes a sliding rope arranged between the connecting balls. An eccentric slider and a buffer device are sleeved on the surface of the sliding rope, and the buffer device is arranged close to the connecting ball.

[0010] Preferably, a rotation induction device is arranged on the inner surface of the housing of the power generation device at a certain distance from the top connecting rod. The rotation induction device includes a rotation induction device housing fixedly connected to the housing of the power generation device. A liquid is arranged inside the rotation induction device housing, and liquid flow direction sensors are equidistantly arranged circumferentially inside the rotation induction device housing.

[0011] Preferably, a signal receiving device is further arranged inside the one-way rotating gear device.

[0012] Preferably, an anchor chain is arranged on the outer surface of the housing of the power generation device.

[0013] Preferably, the rotation induction device housing is of an annular tubular structure, and at least two liquid flow direction sensors are arranged.

[0014] Preferably, the volume of the liquid inside the rotation induction device housing is greater than or equal to the minimum volume and less than or equal to the maximum volume.

[0015] Preferably, when the rotation induction device is perpendicular to the sea level and in a static state, the minimum volume is when the liquid simultaneously contacts the inner wall and the outer wall of the largest diameter segment in the annular tubular structure; when the rotation induction device is perpendicular to the sea level and in a static state, the maximum volume is when the liquid level line submerges the centroid of the rotation induction device housing.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This scheme uses the movement of waves to make the power generation device swing left and right. The circular rack on the shell of the power generation device and the pendulum slide relative to each other around the center of the circle to make the generator rotate. The gear rotation converts the mechanical energy in the swinging process into electrical energy. The swinging direction of the wave power generation device is adjusted to be consistent with the wave movement direction to maximize the power generation power and use a one-way rotating gear device to make the generator rotate in one direction to improve the power generation efficiency. The anti-overturning device is used. In extreme cases, the power generation mechanism can generate electricity normally after overturning in the swinging direction. After overturning sideways, it will automatically return to the power generation posture under the action of the eccentric slider, realizing normal power generation in most cases.

[0018] 2. This scheme completely encloses the power generation device through the power generation device shell, isolates the power generation device from the highly corrosive marine environment, improves the durability of the wave generator, and the circular water retaining surface is large, and its water retaining area is much larger than the water retaining area of ​​the float 7. Under the action of wave force, the power generation device will turn to the direction of the largest wave, so that the swing direction of the swing wave generator is consistent with the direction of wave movement, so as to maximize the power generation.

[0019] 3. The sliding assembly provided in this scheme, on the one hand, serves as a swing buffer device for the whole power generation device under the action of waves. In the case of extreme swing, it can serve as a buffer for wave force, to a certain extent protecting other components such as the swing device, and ensuring the stable operation of the whole device. On the other hand, the sliding assembly also serves as a connecting component between the two floats, used to stabilize the relative state between the floats, in order to ensure the smooth operation of the floats, and then to ensure the stable operation of the whole device from another aspect. At the same time, the sliding assembly also cleverly uses the effect of the waves to increase the length of the relative movement between the pendulum and the rack, further improving the power generation efficiency.

[0020] 4. This scheme sets the boundary conditions of the liquid volume and lists the situations to specifically explain that it can avoid the situations of untimely detection, missed detection and disordered detection of the liquid flow direction as much as possible within the limited conditions, which can greatly reduce the probability of the above situations and improve the detection accuracy as much as possible; at the same time, it protects the driving gear 1 and the driving gear 2 controlled by the one-way rotating gear device.

[0021] 5. This scheme discusses the setting of the liquid flow direction sensor in order to reduce the situation where the rotation sensing device cannot sense or senses untimely when the overall device changes its movement direction, thereby protecting the driving gear 1 and the driving gear 2 controlled by the one-way rotating gear device, and stabilizing the power generation efficiency of the overall power generation device.

Detailed implementation mode

[0040] Example 1: As Figure 1 - Figure 17 shown, the floating one-way rotating generator based on sensing wave swing solves the problem of low conversion efficiency of wave energy of existing offshore power generation equipment. In addition, the present invention also has the following several purposes:

[0041] Purpose one: Make the power generation device swing left and right through the movement of waves, and convert the mechanical energy in the swinging process into electrical energy.

[0042] Purpose two: By adjusting the swinging direction of the wave power generation device to be consistent with the wave movement direction, the power generation power is maximized.

[0043] Purpose three: Adopt a one-way rotating gear device to make the generator 105 rotate in one direction and always rotate towards one direction, improving the power generation efficiency.

[0044] Purpose four: Adopt an eccentric slider to increase the inclination of the swing and improve the power generation efficiency.

[0045] Purpose five: Adopt an anti-overturning device. In extreme cases, after the power generation mechanism overturns in the swinging direction, it can generate electricity normally. After overturning laterally, it will automatically return to the power generation posture under the action of the eccentric slider.

[0046] The power generation principle of this device:

[0047] The main body of the power generation device adopts a cylindrical structure. A pendulum 104 is arranged in the cylindrical structure. Two floats 7 are circumferentially arranged at equal distances at both ends of the cylindrical structure. A pendulum 104 that can swing along the center of the circle is suspended at the center of the circle of the cylindrical structure. A generator 105 is arranged at the bottom of the pendulum 104. A circular track device 4 is arranged on the inner surface of the arc surface of the cylindrical structure. The generator rotating gear 106 of the generator 105 meshes with the rack 401 on the arc surface. Under the action of wave force, the outer shell 6 of the power generation device and the pendulum 104 deflect together or generate relative acceleration. When the vector sum of the downward sliding force generated by the deflection angle and the inertial force generated by the acceleration just makes the generator rotate and generate electricity, the outer shell 6 of the power generation device and the pendulum 104 slide relative to each other around the center of the circle, causing the generator rotating gear 106 connected to the generator 105 to rotate and generate electricity.

[0048] Here, under the action of wave force, theoretically, there will be three situations for the relative displacement generated by the outer shell 6 of the power generation device and the pendulum 104: 1. Only relative rotation angle (downward sliding force generated by the deflection angle); 2. Relative rotation angle + acceleration (vector sum of the downward sliding force generated by the deflection angle and the inertial force generated by the acceleration); 3. Only acceleration (inertial force generated by the acceleration). However, in reality, only situation 2 will occur because there is no absolute horizontal and no absolute zero acceleration under the actual wave action. It should be noted that the above situations need to reach the preset working threshold of the power generation device to work.

[0049] To better understand the above technical solution, the above technical solution will be described in detail below in combination with the accompanying drawings of the specification and specific implementation manners.

[0050] Specifically include:

[0051] The outer shell 6 of the power generation device. Specifically, as Figure 1 shown, the outer shell 6 of the power generation device is a cylindrical structure, which completely encloses the power generation device, isolates the power generation device from the highly corrosive marine environment, improves the durability of the wave generator, and has a very large circular water-retaining surface. Figure 15 The water-retaining area of Figure 17 is much larger than the water-retaining area of

[0052] Under the action of wave force, the power generation device will turn to the direction of the maximum wave, making the swinging direction of the rocking wave generator consistent with the wave movement direction, so as to maximize the power generation.

[0053] Two floats 7 are fixedly connected to both sides of the outer shell 6 of the power generation device. Under the action of waves, the floats 7 float up and down, driving the rack 401 to make a circular motion, and then driving the generator to generate electricity.

[0053] The float 7 is a three-dimensional structure with a hollow interior and can be a three-dimensional structure such as a cylinder, a cuboid, a cube, etc. The optimal solution is a hollow cylinder. At this time, as Figure 1As shown, the plane where the internally hollow cylindrical float 7 is located (the central line in the height direction of the cylinder) forms a certain angle with the plane where the housing 6 of the power generation device is located (the central line in the direction of the circular surface). Here, the angle is preferably perpendicular to maximize the function of the float 7.

[0054] As Figure 2 shown, the float 7 and the housing 6 of the power generation device are respectively fixedly connected to one end of a number of connecting rods 8. A connecting ball 9 is provided at the intersection of the other ends of the number of connecting rods 8. The connecting rods 8 connect the float 7, the housing 6 of the power generation device and the connecting ball 9, and these three are additionally fixed to ensure the connection stability among them. It also transmits the eccentric force generated by the eccentric slider 11 to the float 7, so that the power generation device returns to the power generation posture after tilting laterally. The connecting ball 9 is a connecting member between the connecting rods 8 and the sliding rope 12, and it itself also serves as the connection point for the contact between the connecting rods 8 to stabilize the connection between the connecting rods 8.

[0055] A sliding assembly is provided between the connecting balls 9. The sliding assembly includes a sliding rope 12 provided between the connecting balls 9. The sliding rope 12 can be a rope-like, tubular or other coherent object. Its essence is a slideway for the eccentric slider 11 to slide. Of course, the working environment of the power generation device and other conditions need to be considered here, and specific selection needs to be based on the specific actual situation. An eccentric slider 11 and a buffer device 10 are sleeved on the surface of the sliding rope 12, and the buffer device 10 is arranged close to the connecting ball 9. The buffer device 10 is used as a buffer for the eccentric slider 11 to slow down the action on the connecting ball 9 during the movement of the eccentric slider 11 and extend the service life of the device. The situation of the eccentric slider 11 is relatively complex. The specific functions of setting the eccentric slider 11 are as follows:

[0056] Function 1: When the eccentric slider 11 generates an eccentric moment after tilting laterally in extreme cases, it prompts the power generation device to automatically return to the power generation posture, as Figure 14 shown.

[0057] Function 2: When the power generation device swings to the left, the eccentric slider 11 will also slide to the left synchronously. At this time, due to the change in weight, the total buoyancy on the left side of the power generation device decreases, and the total buoyancy on the right side increases, causing the power generation device to increase its left tilt angle, and the swing device 1 will also move to the left. Similarly, when the power generation device swings to the right under the action of waves, the eccentric slider 11 will also slide to the right synchronously. Due to the change in gravity, the total buoyancy on the right side of the power generation device decreases, and the total buoyancy on the left side increases, causing the power generation device to increase its right tilt angle, and the swing device 1 will also move to the right. In both of the above situations, the length of the relative movement between the pendulum 104 and the rack 401 on the cylindrical structure is increased. The increase in length makes the generator 105 act for a longer time and improves the power generation efficiency.

[0058] Function 3: In extreme environments, such as storms, typhoons, etc., the sea waves fluctuate greatly and the action of the sea waves is complex. At this time, when the eccentric slider 11 changes direction, etc., it will reduce the action of the sea waves on the overall power generation device (reduce the speed of left - right swing transformation), increase the action time of the rotation induction device 5 (frequently switching gears will reduce its service life, see the following for details). To a certain extent, the eccentric slider 11 protects other components associated with it, such as the one - way rotation gear device 2 and the rotation induction device 5.

[0059] In summary, on the one hand, the sliding component serves as a swing buffer device of the overall power generation device under the action of waves. In extreme swing situations, it can buffer the wave force, protect other components such as the swing device 1 to a certain extent, and ensure the stable operation of the overall device. On the other hand, the sliding component also serves as a connecting component between the two floats 7, used to stabilize the relative state between the floats 7. To ensure the stable operation of the floats 7, it further ensures the stable operation of the overall device from another aspect. At the same time, the sliding component also cleverly utilizes the action of the sea waves to increase the length of the relative movement between the pendulum 104 and the rack 401, further improving the power generation efficiency.

[0060] As Figure 2 and Figure 3 shown, a swing device 1 is arranged inside the power generation device housing 6. Under the action of waves, the float 7 floats up and down, driving the rack 401 to make a circular motion. The pendulum 104 and the rack 401 generate relative motion to drive the generator to generate electricity.

[0061] Specifically, the swing device 1 includes a top connecting rod 101 fixedly arranged at the center of the power generation device housing 6. Among them, the top connecting rod 101 is at the center position of the circular surface of the power generation device housing 6, and then a rotating wheel 102 is sleeved, so that the rotating wheel 102 makes a circular motion around the top connecting rod 101. At the same time, the rotation of the rack 401 and the pendulum 104 is made independent, realizing independent rotation. The relative motion between the pendulum 104 and the rack 401 drives the generator 105 to generate electricity. Also, because one side of the rotating wheel 102 is fixedly connected with a swing rod 103, and the swing rod 103 is further connected with a pendulum 104, indirectly realizing the circular motion of the pendulum 104 around the top connecting rod 101 through the rotating wheel 102. A one - way rotation gear device 2 is also arranged at the bottom end of the pendulum 104.

[0062] The one - way rotation gear device 2 specifically includes: a generator 105 is connected to the bottom end of the pendulum 104, which is a direct acting component that converts the mechanical energy of the rotation of the power generation device into electrical energy. Connected to the rotation of the generator 105 is a generator rotation gear 106, and the generator rotation gear 106 can rotate coaxially with the generator 105.

[0063] Several gears are arranged on both sides of the generator rotation gear 106, such asFigure 4 As shown in the figure, the gears from left to right are: the first driving gear 201, the secondary driving gear 203, the generator rotating gear 106, and the second driving gear 202. Among them, the first driving gear 201, the secondary driving gear 203, the generator rotating gear 106, and the second driving gear 202 can mesh with each other pairwise. That is to say, the generator rotating gear 106 is meshed with the secondary driving gear 203 and the second driving gear 202 on both sides respectively (left first and then right). On the other side of the secondary driving gear 203, there is the first driving gear 201, as Figure 5 shown, the first driving gear 201 and the generator rotating gear 106 are arranged relative to the secondary driving gear 203, and the secondary driving gear 203 and the second driving gear 202 are arranged relative to the generator rotating gear 106.

[0064] When the pendulum 104 and the rack 401 move relative to each other, the generator rotating gear 106 rotates to generate electricity (the generator rotating gear 106 rotates coaxially with the generator 105).

[0065] In addition, a circular track device 4 is arranged in a circular ring inside the housing 6 of the power generation device and meshes with the first driving gear 201 and the second driving gear 202 of the one-way rotating gear device 2. Among them, the circular track device 4 includes a circular track beam 402, and a number of racks 401 are equidistantly arranged on the circular track beam 402.

[0066] The first driving gear 201 is the driving gear when the rack 401 moves leftward relative to the generator 105, as Figure 5 shown. When the liquid flow direction sensor 503 senses that the flowing time of the liquid 502 to the left > the start preset time, it will transmit a signal to the one-way rotating gear device 2. After receiving the signal, the one-way rotating gear device 2 lowers the first driving gear 201 and raises the second driving gear 202, so that when the first driving gear 201 meshes with the rack 401, the second driving gear 202 disengages from the rack 401. At this time, the second driving gear 202 idles and does not participate in the power generation process, but still meshes with the generator rotating gear 106, making the gear set rotate coordinately, as Figure 4 shown. The gear set from left to right is that the first driving gear 201 rotates clockwise, the secondary driving gear 203 rotates counterclockwise, the generator rotating gear 106 rotates clockwise, and the second driving gear 202 rotates counterclockwise. At this time, the generator 105 rotates clockwise to generate electricity. It should be noted that the relative displacement between the gears in this process occurs in the elevation direction of the cylindrical power generation device housing 6.

[0067] The second driving gear 202 is the driving gear when the rack 401 moves rightward relative to the generator 105, as Figure 6 shown. From Figure 8 state to Figure 9The state time difference is the predetermined start time of the generator. When the time when the liquid flow direction sensor 503 senses the rightward flow of the liquid 502 > the predetermined start time of the generator, a signal will be transmitted to the one-way rotating gear device 2. After receiving the signal, the one-way rotating gear device 2 lowers the second driving gear 202 and raises the first driving gear 201, so that while the second driving gear 202 meshes with the rack 401, the first driving gear 201 disengages from the rack 401, causing the first driving gear 201 to disengage from the rack. At this time, the first driving gear 201 idles and does not participate in the power generation process, but is still connected to the secondary gear 203, enabling the gear set to rotate in coordination. The gear set from left to right is as follows: the first driving gear 201 rotates clockwise, the secondary gear 203 rotates counterclockwise, the generator rotating gear 106 rotates clockwise, and the second driving gear 202 rotates counterclockwise. At this time, the generator 105 rotates clockwise to generate electricity. It should be noted that the relative displacement that occurs between the gears during this process is in the elevation direction of the cylindrical power generation device housing 6.

[0068] Both the situation where the rack 401 moves leftward relative to the generator 105 and the situation where the rack 401 moves rightward relative to the generator 105 cause the generator 105 to rotate clockwise to generate electricity.

[0069] The secondary gear 203 is the gear connecting the first driving gear 201 and the generator rotating gear 106, and its main function is to transmit the rotational mechanical energy of the driving gear 201 to the generator rotating gear 106.

[0070] Under the action of the waves, the circular track device 4 will move in a circular motion in cooperation with the one-way rotating gear device 2. The rack 401 on the circular track device 4 engages with the first driving gear 201 and the second driving gear 202, thereby driving the generator 105 to generate electricity.

[0071] The disadvantage of the non-motor one-way rotating device is that the up and down movement of the float 7 will cause the generator gears to rotate in two directions. Then, the rotational speed of the generator will have a reverse rotational change after each interval, and extra power is required to start the motor each time, resulting in a large amount of energy loss and serious motor heating, which is prone to danger during actual application. If only considering one-way rotation for power generation, the service life and power generation efficiency of the motor will be greatly improved. The present invention proposes a device that can drive the motor to rotate unidirectionally with the up and down movement of the float. Two driving gears are provided at the generator rotating gear 106, and a secondary gear 203 is provided. The one-way rotation is achieved by adjusting the two driving gears through the rotation sensing device 5 to improve the power generation efficiency, as follows:

[0072] (1) The situation of normal power generation

[0073] The waves on the sea surface cause the inclination of the overall power generation device to be greater than Figure 9All waves in the state are in normal power generation conditions and can also generate electricity normally under the extremely large waves of extreme storms. The power generation device consists of Figure 8 state to Figure 9 state. The rotating induction device housing 501 and the liquid flow direction sensor 503 rotate counterclockwise. The flowing liquid 501 remains horizontal. The liquid flow direction sensor 503 senses that the liquid 502 is moving relatively to the left. From Figure 8 state to Figure 9 The time difference of the state is the predetermined start-up time of the generator. When the time when the liquid flow direction sensor 503 senses the leftward flow > the predetermined start-up time of the generator, it will transmit a signal to the one-way rotating gear device 2. After receiving the signal, the one-way rotating gear device 2 lowers the driving gear 201 and raises the driving gear 202, so that the driving gear 202 disengages from the rack, but still connects to the engine gear 106, enabling coordinated rotation. At this time, the generator rotates clockwise.

[0074] When the power generation device changes from Figure 10 state to Figure 11 state, the rotating induction device housing 501 and the liquid flow direction sensor 503 rotate clockwise. The flowing liquid 501 remains horizontal. The liquid flow direction sensor 503 senses that the liquid is moving relatively to the right. When the time when the liquid flow direction sensor 503 senses the rightward flow > the predetermined start-up time of the generator, it will transmit a signal to the one-way rotating gear device 2. After receiving the signal, the one-way rotating gear device 2 lowers the driving gear 202 and raises the driving gear 201, so that the driving gear 201 disengages from the rack, but still connects to the secondary driving gear 203, enabling coordinated rotation. At this time, the generator rotates clockwise.

[0075] When the power generation device changes from Figure 13 state to Figure 8 state, the rotating induction device housing 501 and the liquid flow direction sensor 503 rotate counterclockwise. The flowing liquid 501 remains horizontal. The liquid flow direction sensor 503 senses that the liquid is moving relatively to the left. When the time when the liquid flow direction sensor 503 senses the leftward flow > the predetermined start-up time of the generator, it will transmit a signal to the one-way rotating gear device 2. After receiving the signal, the one-way rotating gear device 2 lowers the driving gear 201 and raises the driving gear 202, so that the driving gear 202 disengages from the rack, but still connects to the engine gear 106, enabling coordinated rotation. At this time, the generator rotates clockwise.

[0076] (2)No power generation situation

[0077] The waves on the sea surface make the inclination angle of the power generation device not greater than Figure 9 The tiny waves in the state are in the no power generation situation. The power generation device is in Figure 8 state to Figure 9oscillates between states, from Figure 8 state to Figure 9 The time difference between states is the predetermined start-up time of the generator. In this case, when the time when the liquid flow direction sensor 503 senses the rightward flow ≤ the predetermined start-up time of the generator, no signal is transmitted to the one-way rotating gear device 2, and the one-way rotating gear device remains in its original state. The circular structure power generation device housing 6 and the pendulum swing through a small angle together.

[0078] In addition to the above, a swing hammer lateral restraint device 3 is provided between the pendulum 104 and the power generation device housing 6. The swing hammer lateral restraint device 3 includes a lateral connecting rod 301 fixedly connected to the pendulum 104 at one end. The lateral connecting rod 301 is used to connect the pendulum 104 and the roller 302. When the pendulum 104 sways in the elevation direction of the cylindrical power generation device housing 6 under the action of waves, the lateral connecting rods 301 on both sides of the pendulum 104 provide support forces to ensure the stability of the swinging direction; a roller 302 is provided at the other end of the lateral connecting rod 301 of the pendulum 104, and a lateral track 303 matching the roller 302 is arranged around the inside of the power generation device housing 6. The roller 302 is arranged in a matching manner with the lateral track 303, so that the roller 302 can slide along the lateral track 303 in the lateral track 303, specifically as Figure 7 shown.

[0079] When the power generation device is in operation, the rotation sensing device 5 is an essential component. The rotation sensing device 5 adjusts the one-way rotating gear device 2 to realize the one-way rotation power generation of the generator 105 by sensing the rotation direction of the overall power generation device.

[0080] As Figure 8 shown, the rotation sensing device 5 is specifically arranged at the center of the inner surface of the circular surface of the power generation device housing 6. At a certain distance from the top connecting rod 101, the rotation sensing device housing 501 is fixedly connected to the power generation device housing 6. The rotation sensing device housing 501 is hollow inside. Specifically, the rotation sensing device housing 501 can be in various forms, such as a hollow circular tubular structure, such as Figures 8 to 14 shown, where two circular rings with larger diameters are truncated and two circular rings with smaller diameters are truncated and connected at intervals, or multiple annular pipe segments with different pipe diameters are connected, etc.

[0081] It should be noted that, first, each annular pipe segment is arranged on the same circumference (the centers of the circular cross-sections of each annular pipe segment are on the same circumference); second, its essence needs to ensure that the liquid 502 arranged inside can flow freely in the annular tubular structure. However, considering factors such as losses brought by the action of the liquid 502 here, a structure composed of regular straight lines cannot be applied. Therefore, we choose a hollow circular tubular structure.

[0082] Regarding the liquid 502, there are also various selection methods here. If this power generation device is installed in a sea area with relatively violent wave action, a liquid 502 with a relatively large density and viscosity needs to be set inside the rotating induction device housing 501, because a relatively large density and viscosity of the liquid 502 will relatively reduce the effect of wave action and extend the reaction time for the start of the one-way rotating gear device 2; if this power generation device is installed in a sea area with relatively gentle wave action, there are no excessive requirements for the liquid 502 set inside the rotating induction device housing 501, and water or seawater can be used, and the influence can be ignored. In short, the liquid 502 needs to be determined according to specific circumstances.

[0083] Of course, the volume of the liquid 502 also needs to be set here. The volume of the liquid 502 inside the rotating induction device housing 501 needs to meet two conditions simultaneously. One is: greater than or equal to the minimum volume; the other is: less than or equal to the maximum volume; specifically as follows:

[0084] Minimum volume: When the rotating induction device 5 is perpendicular to the sea level (as Figure 8 shown, the annular tubular structure and the power generation device housing 6 are both perpendicular to the sea level at the same time, the centroid of the annular tubular structure is on the diameter extension line of the largest diameter segment, and the diameter extension line of the largest diameter segment is perpendicular to the sea level), and in the static state, the liquid 502 simultaneously contacts the inner wall and the outer wall of the largest diameter segment in the annular tubular structure;

[0085] Maximum volume: When the rotating induction device 5 is perpendicular to the sea level (as Figure 8 shown, the annular tubular structure and the power generation device housing 6 are both perpendicular to the sea level at the same time, the centroid of the annular tubular structure is on the diameter extension line of the largest diameter segment, and the diameter extension line of the largest diameter segment is perpendicular to the sea level), and in the static state, the liquid level line of the liquid 502 submerges the centroid of the annular tubular structure.

[0086] Here, the following terms need to be explained:

[0087] Centroid: The shape center point of the annular tubular structure.

[0088] Largest diameter segment: The annular tubular segment with the largest diameter in the annular tubular structure.

[0089] Inner wall of the largest diameter segment: Taking the annular tubular structure shown in Figure 8 as an example, the shorter curved side in the largest diameter segment of this structure.

[0090] Outer wall of the largest diameter segment: Taking the annular tubular structure shown in Figure 8 as an example, the longer curved side in the largest diameter segment of this structure.

[0091] Specifically, the reasons for setting the volume of the liquid 502 are described by listing the following situations, assuming the following situations:

[0092] Case 1: If the volume of the liquid 502 is less than the minimum volume of the internal volume of the rotation sensing device housing 501, when the whole device is acted upon by waves, the flow direction of the liquid 502 may not be detected in time or may be missed. For example, when the direction is frequently changed by waves, it takes a long time to detect the direction due to the small amount of liquid 502, which may cause the problem of untimely direction change (when two liquid flow direction sensors 503 are provided). In order to reduce the probability of this happening, enough liquid flow direction sensors 503 may be provided, or the volume of the liquid 502 may be increased to meet the limited conditions.

[0093] Case 2: If the volume of liquid 502 occupies a larger volume than the maximum volume of the internal volume of the rotation sensing device housing 501, then when the waves act on the entire device, the flow direction detection of the liquid 502 may often be disordered. For example, the volume of the liquid 502 fills the volume of the rotation sensing device housing 501. When the waves act on the entire device, due to the excessive amount of liquid 502, the flow directions of the liquid 502 detected by different liquid flow direction sensors 503 may be inconsistent. At this time, it is necessary to additionally process the interference signals of different liquid flow direction sensors 503 or set additional detection methods to improve the accuracy of the detection.

[0094] Taking into account Case 1 and Case 2, the volume of the liquid 502 cannot be set arbitrarily. It can avoid the problems of Case 1 and Case 2 as much as possible within the limited conditions, greatly reduce the probability of the above-mentioned situations, and improve the accuracy of detection as much as possible.

[0095] A plurality of liquid flow direction sensors 503 are equidistantly arranged in the circumferential direction inside the rotation sensing device housing 501. The liquid flow direction sensor 503 essentially senses the flow direction of the liquid 502 in contact with it, and then sends a sensing signal to the signal receiving device arranged inside the one-way rotating gear device 2 to control the rise and fall of the driving gear 1 201 and the driving gear 2 202 in the one-way rotating gear device 2.

[0096] The setting of the liquid flow direction sensor 503 needs to be set in combination with the volume of the liquid 502, which is specifically described by the following example:

[0097] Hypothesis 1: The volume of the liquid 502 accounts for half of the internal volume of the rotating induction device housing 501. Since the proportion of the volume of the liquid 502 is 1 / 2, and if we want to sense the movement direction of the liquid 502, then at least liquid flow direction sensors 503 should be set at both ends of the liquid 502 (when in a static state) or at least one liquid flow direction sensor 503 is submerged by the liquid 502. The first setting method is to set the liquid flow direction sensors 503 at the positions of two adjacent points where the circular ring-shaped rotating induction device housing 501 is equally divided into 180°, so that only 2 liquid flow direction sensors 503 need to be set; the second setting method is to set on the outer wall of the maximum pipe diameter section where the liquid flow direction sensor 503 is submerged by the liquid 502. The above two setting methods can ensure that the liquid flow direction sensors 503 are detected during the movement under the condition of setting the minimum number. Of course, if in addition to the above two situations, liquid flow direction sensors 503 are also set at other positions, then the number of liquid flow direction sensors 503 set will be more than 3. Based on the above situation, the number of liquid flow direction sensors 503 set is not less than 2.

[0098] Hypothesis 2: The volume of the liquid 502 is the minimum volume. Since the volume of the liquid 502 is the minimum volume, the number of liquid flow direction sensors 503 set at this time is the denominator of the simplest percentage of the minimum volume accounting for the volume of the rotating induction device housing 501; for example, if the minimum volume accounts for 1 / 3 of the volume of the rotating induction device housing 501, then the number of liquid flow direction sensors 503 set is 3. Because the proportion of the volume of the liquid 502 is 1 / 3, and if we want to sense the movement direction of the liquid 502, then at least liquid flow direction sensors 503 should be set at both ends of the liquid 502 (when in a static state). This setting method is to set the liquid flow direction sensors 503 at the positions of 3 adjacent points where the rotating induction device housing 501 is equally divided into 120°, so that at least 3 liquid flow direction sensors 503 need to be set.

[0099] The purpose of the above-discussed setting situations of the liquid flow direction sensors 503 is to reduce the situation where the rotating induction device 5 cannot sense or senses untimely when the overall device changes its movement direction, thereby protecting the driving gear one 201 and the driving gear two 202 controlled by the one-way rotating gear device 2, and to stabilize the power generation efficiency of the overall power generation device.

[0100] In order to stabilize the power generation area of the overall power generation device, an anchor chain 13 will necessarily be set on the outer surface of the power generation device housing 6 to ensure that the overall power generation device generates electricity stably within a certain area.

[0101] An embodiment of the present invention also provides a floating unidirectional rotation generator based on sensing wave swaying. Combining with the attached drawings, the specific working principle is further elaborated in combination with devices such as the above-mentioned swaying device 1 and unidirectional rotation gear device 2. The specific content is as follows:

[0102] Taking one wave cycle of the wave as an example, specifically Figure 8 → Figure 9 → Figure 10 → Figure 11 → Figure 12 → Figure 8 is a periodic cycle:

[0103] Figure 8 This is the position diagram of the power generation device of the present invention at the trough of the wave;

[0104] Figure 9 This is the position diagram of the power generation device of the present invention when it starts to move from the trough of the wave to the peak just to make the generator generate electricity;

[0105] Figure 10 This is the position diagram of the maximum inclination angle of the power generation device of the present invention when moving from the trough of the wave to the peak;

[0106] Figure 11 This is the position diagram of the power generation device of the present invention at the peak of the wave;

[0107] Figure 12 This is the position diagram of the maximum inclination angle of the power generation device of the present invention when moving from the peak of the wave to the trough;

[0108] When the power generation device moves from Figure 8 state to Figure 9 state, due to the certain mass of the pendulum 104 itself, under the action of the eccentric slider 11 and the wave, the power generation device will deflect left and right around the power generation device housing 6. The power generation device housing 6 and the pendulum 104 deflect together or generate relative acceleration. When the vector sum of the downward sliding force generated by the deflection angle and the inertial force generated by the acceleration just makes the generator rotate and generate electricity at the Figure 9 state, the power generation device housing 6 and the pendulum 104 slide relative to each other around the center of the circle, causing the generator rotation gear 106 connected to the generator 105 to rotate and generate electricity.

[0109] When the power generation device moves from Figure 9 state to Figure 10 , the power generation device housing 6 rotates counterclockwise relative to the pendulum 104 around the center of the circle, causing the generator rotation gear 106 connected to the generator 105 to rotate and generate electricity.

[0110] When the power generation device moves from Figure 10 state to Figure 11, the housing 6 of the power generation device rotates relative to the pendulum 104 clockwise around the center of the circle, causing the generator rotation gear 106 connected to the generator 105 to rotate and generate electricity.

[0111] When the power generation device changes from Figure 11 state to Figure 12 , the housing 6 of the power generation device rotates relative to the pendulum 104 clockwise around the center of the circle, causing the generator rotation gear 106 connected to the generator 105 to rotate and generate electricity.

[0112] When the power generation device changes from Figure 12 state to Figure 8 , the housing 6 of the power generation device rotates relative to the pendulum 104 counterclockwise around the center of the circle, causing the generator rotation gear 106 connected to the generator 105 to rotate and generate electricity.

[0113] The above process takes one wave cycle of the wave as an example to make the structure generate electricity, and the same applies to other situations.

[0114] In this solution, the wave motion causes the power generation device to swing left and right. The circular rack on the housing of the power generation device slides relative to the pendulum around the center of the circle, causing the generator rotation gear to rotate, converting the mechanical energy during the swinging process into electrical energy. By adjusting the swinging direction of the wave power generation device to be consistent with the wave motion direction, the power generation power is maximized. A one-way rotation gear device is used to make the generator rotate in one direction, improving the power generation efficiency. An anti-overturning device is adopted. In extreme cases, after the power generation mechanism overturns in the swinging direction, it can still generate electricity normally. After overturning laterally, it will automatically return to the power generation posture under the action of the eccentric slider, realizing normal power generation in most cases.
