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

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

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

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

[0016] Compared with the prior art, the present invention has the following beneficial effects: 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.

[0017] 2.

[0018] 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.

[0019] 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.

[0020] 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 DESCRIPTION

[0023] Example 1: Figure 1 - Fig.17 As shown, the floating unidirectional rotating generator based on sensing wave sway solves the problem of low conversion efficiency of wave energy in existing offshore power generation equipment. In addition, the present invention also has the following purposes: Purpose 1: To make the power generation device swing left and right through the movement of waves, and convert the mechanical energy during the swinging process into electrical energy.

[0024] Purpose 2: To maximize the power generation by adjusting the swing direction of the wave power generation device to be consistent with the direction of wave movement.

[0025] Purpose three: adopting a one-way rotating gear device to make the generator 105 rotate in one direction all the time, thereby improving the power generation efficiency.

[0026] Purpose 4: Use an eccentric slider to increase the inclination of the swing and improve the power generation efficiency.

[0027] Purpose 5: An anti-overturning device is used. Under extreme circumstances, the power generation mechanism can generate electricity normally after overturning in the swing direction, and will automatically return to the power generation posture under the action of the eccentric slider after overturning sideways.

[0028] The power generation principle of this device: 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 equidistantly arranged 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 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, and the generator rotating gear 106 of the generator 105 is engaged with the rack 401 on the arc surface. Under the action of wave force, the power generation device housing 6 and the pendulum 104 deflect or generate relative acceleration together. When the vector sum of the sliding force generated by the deflection angle and the inertial force generated by the acceleration just makes the generator rotate to generate electricity, the power generation device housing 6 and the pendulum 104 slide relatively around the center of the circle, so that the generator rotating gear 106 connected to the generator 105 rotates to generate electricity.

[0029] Here, under the action of wave force, theoretically, the relative displacement generated by the housing 6 of the power generation device and the pendulum 104 will have three situations: 1. Only relative rotation angle (sliding force generated by the deflection angle); 2. Relative rotation angle + acceleration (the vector sum of the sliding force generated by the deflection angle and the inertial force generated by the acceleration); 3. Only acceleration (inertial force generated by acceleration). However, in reality, only situation 2 will occur, because there is no absolute level 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 in order to work.

[0030] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Specifically include: The power generation device housing 6, specifically, Figure 1 As shown, the housing 6 of the power generation device is a cylindrical structure, which completely encloses the power generation device and isolates the power generation device from the highly corrosive marine environment, thereby improving the durability of the wave generator, and the circular water retaining surface is large. Fig.15 The retaining area is much larger than Fig.17 The retaining area of ​​the rocking wave generator is large. 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 rocking wave generator is consistent with the direction of wave movement, so as to maximize the power generation capacity.

[0032] Floats 7 are fixedly connected to both sides of the power generation device housing 6. 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 rotate and generate electricity.

[0033] The float 7 is a three-dimensional structure with a hollow interior, which can be a cylinder, a cuboid, a cube or the like. The optimal solution is a cylinder with a hollow interior. Figure 1As shown, the plane where the hollow cylindrical float 7 is located (the center line in the height direction of the cylinder) and the plane where the power generation device housing 6 is located (the center line in the direction of the circular surface) form a certain angle. The angle here is preferably vertical to maximize the role of the float 7.

[0034] like Figure 2 As shown, the float 7 and the generator housing 6 are respectively fixedly connected to one end of a plurality of connecting rods 8, and a connecting ball 9 is provided at the intersection of the other ends of the plurality of connecting rods 8. The connecting rod 8 connects the float 7, the generator housing 6 and the connecting ball 9, and the three are additionally fixed to ensure the connection stability between the three. The eccentric force generated by the eccentric slider 11 is also transmitted to the float 7, so that the generator returns to the power generation posture after being overturned laterally. The connecting ball 9 is a connecting piece between the connecting rod 8 and the sliding rope 12, and it itself is also a connection point for contact between the connecting rods 8, which is used to stabilize the connection between the connecting rods 8.

[0035] A sliding assembly is provided between the connecting balls 9, and the sliding assembly includes a sliding rope 12 provided between the connecting balls 9. The sliding rope 12 can be a continuous object such as a rope or a tube, and its essence is a slideway for the sliding of the eccentric slider 11. Of course, the working environment of the power generation device and other conditions need to be considered here, and the specific needs need to be selected according to the actual situation. The surface of the sliding rope 12 is provided with an eccentric slider 11 and a buffer device 10, and the buffer device 10 is provided close to the connecting balls 9. The buffer device 10 serves as a buffer for the eccentric slider 11, which reduces the effect on the connecting balls 9 during the movement of the eccentric slider 11 and prolongs the service life of the device. The situation of the eccentric slider 11 is more complicated, and the specific functions of the eccentric slider 11 are as follows: Function 1: When the eccentric slider 11 overturns laterally in extreme cases, it generates an eccentric torque, which causes the generator to automatically return to the power generation posture, such as Fig.14 shown.

[0036] 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, which increases the inclination of the power generation device to the left, 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, which increases the inclination of the power generation device to the right, and the swing device 1 will also move to the right. The above two situations increase the length of the relative movement between the pendulum 104 and the rack 401 on the cylindrical structure. The increase in length makes the generator 105 work for a longer time, thereby improving the power generation efficiency.

[0037] Function three: In extreme environments, such as storms and typhoons, the sea waves fluctuate greatly and the sea wave action is complex. At this time, the eccentric slider 11 will reduce the sea wave action on the entire power generation device when changing direction (reduce the speed of left and right swinging), and increase the action time of the rotation sensing device 5 (frequent gear switching will reduce its service life, see below for details). The eccentric slider 11 protects other components associated with it to a certain extent, such as the one-way rotating gear device 2 and the rotation sensing device 5.

[0038] In summary, the sliding assembly, on the one hand, serves as a swing buffer device for the entire power generation device under the action of waves. In extreme swing conditions, it can serve as a buffer for wave forces, protecting other components such as the swing device 1 to a certain extent, and ensuring the stable operation of the entire device. On the other hand, the sliding assembly also serves as a connecting component between the two floats 7, used to stabilize the relative state between the floats 7, in order to ensure the smooth operation of the floats 7, and then to ensure the stable operation of the entire device from another aspect. At the same time, the sliding assembly also cleverly uses the action of the waves to increase the length of the relative movement between the pendulum 104 and the rack 401, further improving the power generation efficiency.

[0039] like Figure 2 and Figure 3 As shown, a swing device 1 is arranged inside the housing 6 of the power generation device. Under the action of waves, the float 7 of the swing device 1 floats up and down, driving the rack 401 to make a circular motion, and the pendulum 104 and the rack 401 generate mutual motion to drive the generator to generate electricity.

[0040] Specifically, the swing device 1 includes a top connecting rod 101 fixedly arranged at the center of the generator housing 6, wherein the top connecting rod 101 is the center position of the circular surface of the generator housing 6, and a rotating wheel 102 is set behind it, so that the rotating wheel 102 makes a circular motion around the top connecting rod 101, and at the same time, the rotation of the rack 401 and the pendulum 104 are independent, so that independent rotation is achieved, and the pendulum 104 and the rack 401 produce relative motion to drive the generator 105 to generate electricity, and because one side of the rotating wheel 102 is fixedly connected to the swing rod 103, and the swing rod 103 is further connected to the pendulum 104, the pendulum 104 is indirectly realized to make a circular motion around the top connecting rod 101 through the rotating wheel 102. A one-way rotating gear device 2 is also provided at the bottom of the pendulum 104.

[0041] The one-way rotating 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 generator device into electrical energy. A generator rotating gear 106 is rotatably connected to the generator 105, and the generator rotating gear 106 can rotate coaxially with the generator 105.

[0042] Several gears are arranged on both sides of the generator rotating gear 106, such as Figure 4 As shown, the gears from left to right are: driving gear 1 201, secondary gear 203, generator rotating gear 106, driving gear 2 202. Among them, the driving gear 1 201, secondary gear 203, generator rotating gear 106, and driving gear 2 202 can be meshed with each other in pairs, that is, the generator rotating gear 106 is meshed with secondary gear 203 and driving gear 2 202 on both sides (first left and then right), and the other side of the secondary gear 203 is provided with driving gear 1 201, as shown in FIG. Figure 5 As shown, the driving gear 1 201 and the generator rotating gear 106 are arranged relative to the secondary driving gear 203 , and the secondary driving gear 203 and the driving gear 2 202 are arranged relative to the generator rotating gear 106 .

[0043] 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).

[0044] In addition, a circular track device 4 is arranged in a circle inside the power generation device housing 6 and meshes with the driving gear 1 201 and the driving gear 2 202 of the unidirectional rotating gear device 2, wherein the circular track device 4 includes a circular track beam 402 on which a plurality of racks 401 are equidistantly arranged.

[0045] The driving gear 1 201 is the driving gear that acts when the rack 401 moves to the left relative to the generator 105. Figure 5 When the liquid flow direction sensor 503 senses that the liquid 502 flows to the left for a time greater than the start-up preset time, 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 driving gear 1 201 and raises the driving gear 2 202, so that the driving gear 1 201 engages with the rack 401 while the driving gear 2 202 disengages from the rack 401. At this time, the driving gear 2 202 idles and does not participate in the power generation process, but still engages with the generator rotating gear 106, so that the gear set rotates in coordination, as shown in FIG. Figure 4 As shown. The gear set from left to right is, the driving gear 1 201 rotates clockwise, the secondary gear 203 rotates counterclockwise, the generator gear 106 rotates clockwise, the driving gear 2 202 rotates counterclockwise, and the generator 105 rotates clockwise to generate electricity. It should be noted that the relative displacement between the gears in this process is carried out in the elevation direction of the cylindrical power generation device housing 6.

[0046] The second driving gear 202 is the driving gear that acts when the rack 401 moves to the right relative to the generator 105. Figure 6 As shown. Figure 8 Status to Fig. 9The state time difference is the scheduled start time of the generator. When the liquid flow direction sensor 503 senses that the time when the liquid 502 flows to the right is greater than the scheduled 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 driving gear 2 202 and lifts the driving gear 1 201, so that the driving gear 2 202 engages with the rack 401 and the driving gear 1 201 disengages from the rack 401, so that the driving gear 1 201 disengages from the rack. At this time, the driving gear 1 201 idles and does not participate in the power generation process, but is still connected to the secondary gear 203, so that the gear set rotates in coordination. The gear set is from left to right, the driving gear 1 201 rotates clockwise, the secondary gear 203 rotates counterclockwise, the generator rotating gear 106 rotates clockwise, the driving gear 2 202 rotates counterclockwise, and the generator 105 rotates clockwise to generate electricity. It should be noted that the relative displacement between the gears in this process is carried out in the elevation direction of the cylindrical power generation device housing 6.

[0047] When the rack 401 moves to the left relative to the generator 105 or when the rack 401 moves to the right relative to the generator 105, the generator 105 rotates clockwise to generate electricity.

[0048] The secondary gear 203 is a gear connecting the driving gear 1 201 and the generator rotating gear 106 , and is mainly used to transfer the rotational mechanical energy of the driving gear 201 to the generator rotating gear 106 .

[0049] Under the action of waves, the circular track device 4 will cooperate with the one-way rotating gear device 2 to make circular motion, and the rack 401 on the circular track device 4 will mesh with the driving gear 1 201 and the driving gear 2 202, thereby driving the generator 105 to generate electricity.

[0050] The disadvantage of a one-way rotation device without a motor is that the up and down movement of the float 7 will cause the generator gear to rotate in two directions, and the generator rotation speed will have a reverse rotation change after each pause. Extra power must be used to start the motor each time, which results in a large energy loss and serious motor heating. This can easily lead to dangers during actual application. If only one direction of rotation is considered for power generation, the life of the motor and the power generation efficiency will be greatly improved. The present invention proposes a device that can drive the motor to rotate in one direction when the float moves up and down. Two driving gears are set at the generator rotating gear 106, and a secondary driving gear 203 is set. The two driving gears are adjusted by the rotation sensing device 5 to achieve one-way rotation, thereby improving the power generation efficiency. The details are as follows: (1) Normal power generation The waves on the sea surface make the overall power generation device tilted greater than Fig. 9 All waves in this state are normal power generation conditions, and normal power generation can also be achieved under extremely large waves in extreme storms. Figure 8 Status to Fig. 9 The rotation sensing device housing 501 and the liquid flow direction sensor 503 rotate counterclockwise, the flowing liquid 501 remains horizontal, and the liquid flow direction sensor 503 senses that the liquid 502 is moving relatively to the left. Figure 8 Status to Fig. 9 The state time difference is the scheduled start time of the generator. When the liquid flow direction sensor 503 senses that the leftward flow time is greater than the scheduled 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 driving gear 201 and lifts the driving gear 202, so that the driving gear 202 is disengaged from the rack, but is still connected to the engine gear 106, so that the coordinated rotation is achieved. At this time, the generator rotates clockwise.

[0051] When the power generation device Fig.10 Status to Fig.11 State, the rotation sensing device housing 501 and the liquid flow direction sensor 503 rotate clockwise, the flowing liquid 501 remains horizontal, and the liquid flow direction sensor 503 senses that the liquid is moving relatively to the right. When the liquid flow direction sensor 503 senses that the rightward flow time is greater than 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 driving gear 202 and lifts the driving gear 201, so that the driving gear 201 is disengaged from the rack, but is still connected to the secondary driving gear 203, so that the coordinated rotation is achieved. At this time, the generator rotates clockwise.

[0052] When the power generation device Fig.13 Status to Figure 8 State, the rotation sensing device housing 501 and the liquid flow direction sensor 503 rotate counterclockwise, the flowing liquid 501 remains horizontal, and the liquid flow direction sensor 503 senses that the liquid is moving relatively to the left. When the liquid flow direction sensor 503 senses that the leftward flow time is greater than 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 driving gear 201 and lifts the driving gear 202, so that the driving gear 202 is disengaged from the rack, but is still connected to the engine gear 106, so as to coordinate the rotation. At this time, the generator rotates clockwise.

[0053] (2) No power generation The waves on the sea surface make the inclination angle of the power generation device no greater than Fig. 9 The small waves in the state are not generating electricity, and the power generation device is Figure 8 Status to Fig. 9 The state swings between Figure 8 Status to Fig. 9The state time difference is the scheduled start time of the generator. In this case, when the time when the liquid flow direction sensor 503 senses the rightward flow is ≤ the scheduled start time of the generator, no signal will be transmitted to the one-way rotating gear device 2. The one-way rotating gear device maintains its original state, and the circular structure generator housing 6 and the pendulum swing at a small angle together.

[0054] In addition to the above, a swinging hammer lateral restraint device 3 is provided between the pendulum 104 and the housing 6 of the power generation device. The swinging hammer lateral restraint device 3 includes a lateral connecting rod 301 with one end fixedly connected to the pendulum 104. The lateral connecting rod 301 is used to connect the pendulum 104 and the roller 302. When the pendulum 104 is shaken in the elevation direction of the cylindrical power generation device housing 6 by the force of waves, the lateral connecting rods 301 on both sides of the pendulum 104 provide supporting force to ensure the stability of the swinging direction; the other end of the lateral connecting rod 301 of the pendulum 104 is provided with a roller 302, 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 matched with the lateral track 303 so that the roller 302 can slide along the lateral track 303 in the lateral track 303, as shown in FIG. Figure 7 shown.

[0055] When the power generation device is in operation, the rotation sensing device 5 is an essential functioning component. The rotation sensing device 5 adjusts the unidirectional rotation gear device 2 to realize the unidirectional rotation power generation of the generator 105 by sensing the rotation direction of the entire power generation device.

[0056] like Figure 8 As 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. The rotation sensing device housing 501 is fixedly connected to the power generation device housing 6 at a certain distance from the top connecting rod 101. The rotation sensing device housing 501 is hollow inside. The specific rotation sensing device housing 501 can be in various forms, such as a hollow circular tubular structure, such as Figures 8 to 14 The arrangement forms shown are as follows: two sections of circular ring segments with larger diameters are connected with two sections of circular ring segments with smaller diameters at intervals, and multiple sections of annular pipe segments with different diameters are connected.

[0057] It should be noted that, firstly, the annular tube segments are arranged on the same circumference (the centers of the circular cross sections of the annular tube segments are on the same circumference); secondly, it is essential to ensure that the liquid 502 disposed inside can flow freely in the annular tubular structure, but here factors such as the loss caused by the action of the liquid 502 need to be considered, and then the structure composed of regular straight lines cannot be applied, so we choose a circular tubular structure with a hollow interior.

[0058] As for the liquid 502, there are also a variety of options. If the power generation device is set in a sea area with more severe wave action, a liquid 502 with a larger density and a larger viscosity needs to be set inside the rotation sensing device shell 501, because the larger density and higher viscosity of the liquid 502 will relatively reduce the effect of the wave action and prolong the reaction time of the one-way rotating gear device 2 starting; if the power generation device is set in a sea area with relatively gentle wave action, there are no excessive requirements for the liquid 502 set inside the rotation sensing device shell 501, and water or seawater can be used, and the impact can be ignored. In short, the liquid 502 needs to be determined according to the specific situation.

[0059] Of course, the volume of the liquid 502 needs to be set here. The volume of the liquid 502 in the rotation sensing device housing 501 needs to meet two conditions at the same time. First, it is greater than or equal to the minimum volume; second, it is less than or equal to the maximum volume. The details are as follows: Minimum volume: When the rotation sensing device 5 is perpendicular to the sea level (such as Figure 8 As shown, the annular tubular structure and the power generation device housing 6 are both perpendicular to the sea level, the centroid of the annular tubular structure is on the extension line of the diameter of the maximum diameter segment and the extension line of the diameter of the maximum diameter segment is perpendicular to the sea level), and in a static state, the liquid 502 simultaneously contacts the inner wall and the outer wall of the maximum diameter segment in the annular tubular structure; Maximum volume: When the rotation sensing device 5 is perpendicular to the sea level (such as Figure 8 As shown, the annular tubular structure and the power generation device casing 6 are both perpendicular to the sea level, the centroid of the annular tubular structure is on the extension line of the diameter of the maximum diameter segment and the extension line of the diameter of the maximum diameter segment is perpendicular to the sea level), and in a static state, the liquid level line of the liquid 502 submerges the centroid of the annular tubular structure.

[0060] Here, the following terms need to be explained: Centroid: The center point of the shape of a circular tubular structure.

[0061] Maximum diameter segment: The annular tubular segment with the largest diameter in the annular tubular structure.

[0062] Inner wall of the largest diameter segment: Figure 8 Taking the annular tubular structure shown as an example, the shorter curved edge in the maximum diameter segment of this structure.

[0063] The outer wall of the largest diameter segment: Figure 8 Taking the annular tubular structure shown as an example, the longer curved edge in the maximum diameter segment of this structure.

[0064] Specifically, the reasons for setting the volume of the liquid 502 are described by listing the following situations, assuming the following situations: 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. 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.

[0065] 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.

[0066] 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.

[0067] 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: Assumption 1: The volume of the liquid 502 occupies half of the internal volume of the rotation sensing device housing 501. Because the volume of the liquid 502 accounts for 1 / 2, and if you want to sense the direction of movement of the liquid 502, then at least two liquid flow direction sensors 503 must be set at the two ends of the liquid 502 (when it is stationary) or at least one liquid flow direction sensor 503 must be submerged in the liquid 502. The first setting method is to set the liquid flow direction sensors 503 at the positions of two adjacent points of the ring-shaped rotation sensing device housing 501 that are equally divided by 180°, so that only two liquid flow direction sensors 503 need to be set; the second setting method is to set the liquid flow direction sensors 503 on the outer wall of the largest diameter section of the pipe submerged by the liquid 502; the above two setting methods can ensure that the liquid flow direction sensors 503 are detected during the movement process when the minimum number is set. 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 greater than 3. Based on the above situation, the number of liquid flow direction sensors 503 set is not less than 2.

[0068] Assumption 2: The volume of the liquid 502 is the minimum volume. Because the volume of the liquid 502 is the minimum volume, the number of liquid flow direction sensors 503 to be set is the denominator of the simplest percentage of the minimum volume to the volume of the rotation sensing device housing 501; for example, the minimum volume accounts for 1 / 3 of the volume of the rotation sensing device housing 501, then the number of liquid flow direction sensors 503 to be set is 3, because the proportion of the volume of the liquid 502 is 1 / 3, and if you want to sense the movement direction of the liquid 502, then at least liquid flow direction sensors 503 must be set at both ends of the liquid 502 (when it is static). This setting method is to set the liquid flow direction sensors 503 at the positions of 3 adjacent points of the rotation sensing device housing 501 that are equally divided into 120°, so that at least 3 liquid flow direction sensors 503 need to be set.

[0069] The purpose of the above-discussed setting of the liquid flow direction sensor 503 is to reduce the situation where the rotation sensing device 5 cannot sense or senses in time when the overall device changes its movement direction, thereby protecting the driving gear 1 201 and the driving gear 2 202 controlled by the one-way rotating gear device 2, and stabilizing the power generation efficiency of the overall power generation device.

[0070] In order to stabilize the power generation area of ​​the entire power generation device, an anchor chain 13 must be provided on the outer surface of the power generation device housing 6 to ensure that the entire power generation device generates power stably within a certain area.

[0071] The embodiment of the present invention further provides a floating unidirectional rotating generator based on sensing wave sway. In combination with the accompanying drawings, the specific working principle is combined with the above-mentioned swaying device 1, the unidirectional rotating gear device 2 and other devices to further explain the working principle of the power generation device, as follows: Taking a wave cycle of a wave as an example, the specific Figure 8 → Fig. 9 → Fig.10 → Fig.11 → Fig.12 → Figure 8 It is a periodic cycle: Figure 8 This is a diagram showing the power generation device of the present invention at the trough of a wave; Fig. 9 The power generation device of the present invention moves from the trough of the wave to the crest of the wave just to make the generator generate electricity; Fig.10 It is a diagram showing the maximum inclination position of the power generation device of the present invention when it moves from the trough of the wave to the crest of the wave; Fig.11 This is a diagram showing the power generation device of the present invention at the crest of a wave; Fig.12 It is a diagram showing the maximum inclination position of the power generation device of the present invention when it moves from the crest of a wave to the trough of a wave; When the power generation device Figure 8 Status to Fig. 9 In this state, since the pendulum 104 itself has a certain mass, under the action of the eccentric slider 11 and the waves, the generator will deflect left and right around the generator housing 6, and the generator housing 6 and the pendulum 104 will deflect or generate relative acceleration together. When the vector sum of the sliding force generated by the deflection angle and the inertial force generated by the acceleration just makes the generator rotate to generate electricity Fig. 9 In this state, the housing 6 of the power generation device and the pendulum 104 slide relative to each other around the center of the circle, so that the generator rotating gear 106 connected to the generator 105 rotates to generate electricity.

[0072] When the power generation device Fig. 9 Status to Fig.10 The housing 6 of the power generation device rotates counterclockwise relative to the pendulum 104 around the center of the circle, so that the generator rotating gear 106 connected to the generator 105 rotates to generate electricity.

[0073] When the power generation device Fig.10 Status to Fig.11 The housing 6 of the power generation device rotates clockwise relative to the pendulum 104 around the center of the circle, so that the generator rotating gear 106 connected to the generator 105 rotates to generate electricity.

[0074] When the power generation device Fig.11 Status to Fig.12The housing 6 of the power generation device rotates clockwise relative to the pendulum 104 around the center of the circle, so that the generator rotating gear 106 connected to the generator 105 rotates to generate electricity.

[0075] When the power generation device Fig.12 Status to Figure 8 The housing 6 of the power generation device rotates counterclockwise relative to the pendulum 104 around the center of the circle, so that the generator rotating gear 106 connected to the generator 105 rotates to generate electricity.

[0076] The above process is to use a wave cycle of a wave as an example to make the structure generate electricity, and other cases can be deduced by analogy.

[0077] 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. An 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, thereby achieving normal power generation in most cases.
