[0053] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0054] The inventor analyzed the reason for the low power generation efficiency of the pile column type tidal current power generating set, and found that:

[0055] According to fluid mechanics, the speed of water flow at different depths is parabolic distribution, the speed of water body at the water surface is the largest, and decreases along the depth direction. When the pile column type tidal current power generating set is running, it is at a fixed water depth underwater, when the speed of water flow reaches the starting speed of the pile column type tidal current power generating set, the pile column type tidal current power generating set starts to run and generate electricity, and when the speed of water flow is lower than the starting speed of the pile column type tidal current power generating set, the pile column type tidal current power generating set stops.

[0056] However, the inventor found that when the speed of water flow at the depth where the pile column type tidal current power generating set is located is lower than the starting speed of the pile column type tidal current power generating set, the speed of water flow at the upper layer of the pile column type tidal current power generating set may reach the starting speed of the pile column type tidal current power generating set, that is, the power generation condition is met, at this time, the water flow at the upper layer of the pile column type tidal current power generating set is not utilized by the pile column type tidal current power generating set, thereby affecting the energy utilization rate of the pile column type tidal current power generating set, shortening the power generation hours, leading to that the pile column type tidal current power generating set cannot fully utilize the tidal current energy resources, and further leading to the low power generation efficiency of the pile column type tidal current power generating set.

[0057] Secondly, the size of the pile foundation is large, and there is a water blocking effect, which reduces the speed of the water flow to a certain extent, thereby reducing the power generation efficiency of the tidal current power generation set in front of the pile.

[0058] In addition, vortex zones are easily generated behind the pile, causing the tidal current power generation set to vibrate, threatening the safe operation of the pile column type tidal current power generation set.

[0059] In view of this, in order to improve the power generation efficiency, the present application is proposed.

[0060] Referring to Figures 1-2 , a schematic diagram of a height adjustment system of a tidal current power generation set of the present application is shown, which comprises:

[0061] The first pile foundation 01, the second pile foundation 02, the first gear box 03, the second gear box 04, the transverse shaft 05, the longitudinal shaft 06, the steering motor 07, the tidal current power generation set 08 and the water flow detection device 09.

[0062] The first pile foundation and the second pile foundation are respectively vertically rock-embedded installed on the seabed, and the top of the first pile foundation and the top of the second pile foundation are level and both exposed above the sea level.

[0063] The first gear box is fixedly arranged at the top of the first pile foundation, and the second gear box is fixedly arranged at the top of the second pile foundation.

[0064] For example, the first gear box is rigidly connected with the top of the first pile foundation, and the second gear box is rigidly connected with the top of the second pile foundation.

[0065] The transverse shaft has two ends, which are respectively a first end and a second end.

[0066] The first end of the transverse shaft is rotatably connected with the first gear box, and the second end of the transverse shaft is rotatably connected with the second gear box.

[0067] For example, the first end of the transverse shaft is toothed with the planetary gear set in the first gear box, so as to realize the rotatable connection between the transverse shaft and the first gear box through the planetary gear set.

[0068] In addition, the second end of the transverse shaft is toothed with the planetary gear set in the second gear box, so as to realize the rotatable connection between the transverse shaft and the second gear box through the planetary gear set. The cross section of the transverse shaft can be circular, etc.

[0069] The steering motor is arranged at the middle part of the transverse shaft.

[0070] The longitudinal shaft has two ends, which are respectively a first end and a second end.

[0071] The bottom of the steering motor is rotationally connected with the first end of the longitudinal shaft, and the second end of the longitudinal shaft is connected with the top of the tidal current generator set.

[0072] The steering motor is used to drive the longitudinal shaft to rotate with the central axis of the longitudinal shaft as the rotation axis (the direction of the central axis of the longitudinal shaft is the same as the length direction of the longitudinal shaft), that is, the steering motor is used to drive the longitudinal shaft to rotate around its own axis.

[0073] Since the second end of the longitudinal shaft is connected with the top of the tidal current generator set, the steering motor drives the longitudinal shaft to rotate with the central axis of the longitudinal shaft as the rotation axis, so that the orientation of the tidal current generator set can be changed, for example, the orientation of the impeller installed on the side of the tidal current generator set is changed, so that the impeller is perpendicular to the incoming flow direction of the water flow (that is, the plane in which the plurality of blades of the impeller is perpendicular to the incoming flow direction of the water flow), so as to improve the power generation efficiency of the tidal current generator set.

[0074] The angle range in which the steering motor drives the longitudinal shaft to rotate with the central axis of the longitudinal shaft as the rotation axis can be 0-360 degrees, that is, the angle range in which the longitudinal shaft rotates around its own axis can be 0-360 degrees.

[0075] The first gear box and the second gear box are used to drive the transverse shaft to rotate with the central axis of the transverse shaft as the rotation axis (the direction of the central axis of the transverse shaft is the same as the length direction of the transverse shaft), that is, the first gear box and the second gear box are used to drive the transverse shaft to rotate around its own axis.

[0076] The angle range in which the first gear box and the second gear box drive the transverse shaft to rotate with the central axis of the transverse shaft as the rotation axis can be 0-180 degrees, and the angle in the angle range can also be understood as the angle between the longitudinal shaft and the sea level.

[0077] The first gear box and the second gear box can simultaneously drive the respective planetary gear sets to work in the same direction (for example, rotate) to drive the transverse shaft to rotate with the central axis of the transverse shaft as the rotation axis.

[0078] The first gear box and the second gear box drive the transverse shaft to rotate with the central axis of the transverse shaft as the rotation axis, which changes the angle between the longitudinal shaft and the sea level, for example, changes the height of the second end of the longitudinal shaft, and further changes the height of the tidal current generator set connected with the second end of the longitudinal shaft.

[0079] For example, the height of the tidal current generator set connected with the second end of the longitudinal shaft is increased, so that the tidal current generator set is exposed above the sea level and is in a lifting state, in which the tidal current generator set is convenient for maintenance and repair by the staff.

[0080] For another example, the height of the tidal current generator set connected with the second end of the longitudinal shaft is reduced, so that the tidal current generator set is located below the sea level and in a lowered state, in which the tidal current generator set can work and generate electricity.

[0081] In the present application, the depth can be understood as the vertical distance from the sea level. The height can be understood as the vertical distance from the sea bed.

[0082] The present application flexibly and stably adjusts the horizontal height of the tidal current generator set in a large range with low hardware cost through the first gear box, the second gear box, the transverse shaft and the longitudinal shaft.

[0083] The water flow detection device is arranged on the side of the first pile foundation or the side of the second pile foundation, and is used to detect the speed and / or main flow direction of the water flow at multiple depths in the area where the horizontal height adjustment system of the tidal current generator set is located.

[0084] The water flow detection device can include an Acoustic Doppler Current Profiler (ADCP) or the like. Of course, it can be understood that other types of water flow detection devices can also be included, and the specific type of the water flow detection device is not limited in the present application.

[0085] The Acoustic Doppler Current Profiler is a kind of velocity measuring sonar equipment developed by integrating multiple disciplines such as underwater acoustic physics, underwater acoustic transducer design, electronic technology and signal processing. As an application of underwater acoustic technology, Doppler current measurement provides a comprehensive application platform for these related disciplines. By using the principle of acoustic Doppler, the frequency shift information of the scattering signal of layered water medium is measured, and the vertical profile of the water flow, i.e. the vertical profile distribution of the water flow, is obtained by using the vector synthesis method. The measured flow field does not produce any disturbance, and there is no mechanical inertia and mechanical wear. It can measure the three-dimensional components and absolute direction of the water flow velocity of several layers on one profile at a time, and is a kind of underwater current measuring instrument.

[0086] The water flow detection device can realize the detection of the speed and main flow direction of the water flow at each depth in the vertical direction, and can control the start / stop of the tidal current generator set, control the rotation of the longitudinal shaft driven by the steering motor with the central axis of the longitudinal shaft as the rotation axis, control the rotation of the transverse shaft driven by the first gear box and the second gear box with the central axis of the transverse shaft as the rotation axis, control the working of the hydraulic assembly (such as retracting the hydraulic rod, etc.), and the like.

[0087] The required electric energy of the water flow detection device can be supplied from the outside or supplied by the energy storage device, and the electric energy stored by the energy storage device can be the electric energy generated by the tidal current generator set.

[0088] In another embodiment of the present application, the system further comprises the connecting assembly 10.

[0089] Referring to Figure 3 The connecting assembly 10 comprises a connecting plate 101, a first hydraulic assembly 102, a second hydraulic assembly 103, a first hinged member 104, and a second hinged member 105.

[0090] The second end of the longitudinal shaft is rotatably connected to the top of the tidal current generator set via the connecting assembly.

[0091] The end of the second end of the longitudinal shaft is fixedly connected to the first face of the connecting plate.

[0092] The hydraulic body of the first hydraulic assembly is fixedly connected to the second face of the connecting plate.

[0093] The hydraulic body of the second hydraulic assembly is fixedly connected to the second face of the connecting plate.

[0094] The hydraulic rod of the first hydraulic assembly is rotatably connected to the top of the tidal current generator set via the first hinged member.

[0095] The hydraulic rod of the second hydraulic assembly is rotatably connected to the top of the tidal current generator set via the second hinged member.

[0096] The first hydraulic assembly is used to adjust the extension length of the first hydraulic rod, and the second hydraulic assembly is used to adjust the extension length of the second hydraulic rod, so as to adjust the included angle between the platform of the top of the tidal current generator set and the longitudinal shaft, and further adjust the horizontal angle of the platform of the top of the tidal current generator set.

[0097] In another embodiment of the present application, the connecting assembly 10 further comprises a plurality of oblique supporting members 106.

[0098] The first end of each oblique supporting member is fixedly connected (e.g. rigidly connected, etc.) to the side face of the second end of the longitudinal shaft, and the second end of each oblique supporting member is fixedly connected (e.g. rigidly connected, etc.) to the first face of the connecting plate.

[0099] The positions on the side face of the second end of the longitudinal shaft, where the first end of each oblique supporting member is connected, can be uniformly distributed.

[0100] The positions on the first face of the connecting plate, where the second end of each oblique supporting member is connected, can also be uniformly distributed.

[0101] In this way, the uniformity of the stress can be improved, so as to improve the stability.

[0102] Referring to Figure 4In another embodiment of the present application, the first hinge 104 comprises a first pin shaft 1041 and a first pin 1042, the first pin shaft is fixedly arranged on the first hydraulic rod, and the first pin is fixedly arranged on the top of the tidal current generator set. The first pin shaft and the first pin cooperate to achieve rotary connection.

[0103] In addition, the second hinge comprises a second pin shaft and a second pin, the second pin shaft is fixedly arranged on the second hydraulic rod, and the second pin is fixedly arranged on the top of the tidal current generator set. The second pin shaft and the second pin cooperate to achieve rotary connection.

[0104] In addition, the second hinge comprises a second pin shaft and a second pin, the second pin shaft is fixedly arranged on the second hydraulic rod, and the second pin is fixedly arranged on the top of the tidal current generator set. The second pin shaft and the second pin cooperate to achieve rotary connection. Figure 1

[0105] Figure 2 In addition, the second hinge comprises a second pin shaft and a second pin, the second pin shaft is fixedly arranged on the second hydraulic rod, and the second pin is fixedly arranged on the top of the tidal current generator set. The second pin shaft and the second pin cooperate to achieve rotary connection.

[0106] In another embodiment of the present application, the top of the tidal current generator set has a platform, and a fence is arranged on the periphery of the platform, which can improve the safety of the workers when working on the platform at the top of the tidal current generator set.

[0107] In another embodiment of the present application, a ladder is arranged on the side of the tidal current generator set, which can facilitate the workers to go to the platform at the top of the tidal current generator set through the ladder.

[0108] In another embodiment of the present application, a warning assembly is arranged on the top of the first gear box and / or the top of the second gear box, which can warn passing ships and reduce the risk of collision between the horizontal height adjustment system of the tidal current generator set and other ships, thereby improving safety.

[0109] In another embodiment of the present application, the bottom of the steering motor is connected to the end of the first end of the longitudinal shaft through a flange, for example, fixed connection or rigid connection through a flange.

[0110] The bottom of the steering motor is provided with a flange, and the end of the first end of the longitudinal shaft is provided with a flange, and the two flanges are connected through bolts, which improves the disassembly and facilitates installation and maintenance. A gasket can be added between the two flanges to form a seal. Alternatively, the two flanges are connected through welding, so that the connection strength is increased.

[0111] ​The flange is beneficial to installation and dismounting, can tightly connect the steering motor and the first end of the longitudinal shaft, effectively controls the vibration and displacement generated in the process that the steering motor drives the longitudinal shaft to rotate with the central axis of the longitudinal shaft as the rotating shaft, and thus improves the stability of rotation. In the process that the steering motor drives the longitudinal shaft to rotate with the central axis of the longitudinal shaft as the rotating shaft, the flange can uniformly bear stress, avoids damage or failure caused by stress concentration, and prolongs the service life.

[0112] In another embodiment of the present application, the shape of the cross section of the longitudinal shaft is an ellipse. In the vertical state of the longitudinal shaft, the direction of the major axis of the ellipse is parallel to the direction of the water flow, which is beneficial to reducing the water flow resistance.

[0113] In another embodiment of the present application, the shape of the cross section of the longitudinal shaft is a rhombus. In the vertical state of the longitudinal shaft, the direction of the major axis of the rhombus is parallel to the direction of the water flow, which is beneficial to reducing the water flow resistance.

[0114] In the tidal current generator set of the present application, two impellers are arranged, for example, a first impeller and a second impeller are arranged on opposite or facing away sides of the tidal current generator set. The two sides are located on two sides of the plane in which the center of the tidal current generator set, the center of the first pile foundation and the center of the second pile foundation are located.

[0115] In the scenario of rising tide, the first impeller works to generate electricity, and the second impeller does not work. In the scenario of falling tide, the second impeller works to generate electricity, and the first impeller does not work. Thus, the tidal current generator set of the present application can generate electricity in the scenarios of rising tide and falling tide, can improve the power capture efficiency, can improve the power generation efficiency, and reduces the cost.

[0116] In the scenario of rising tide, the first impeller works to generate electricity, and the second impeller does not work. In the scenario of falling tide, the second impeller works to generate electricity, and the first impeller does not work. Thus, the tidal current generator set of the present application can generate electricity in the scenarios of rising tide and falling tide, can improve the power capture efficiency, can improve the power generation efficiency, and reduces the cost. Figure 5 FIG. 1 is a schematic view of a height adjustment system of a tidal current generator set in a lowered state.

[0117] Figure 6 FIG. 2 is a schematic view of a height adjustment system of a tidal current generator set in a raised state.

[0118] In another embodiment of the present application, the tidal current generator set can also adjust its direction to face the main flow direction of the water flow, so that the power generation mechanism (for example, the impeller) is directly opposite the main flow direction of the water flow, and the power generation efficiency is improved.

[0119] The horizontal height adjustment system of the tidal current power generating set can quickly and stably raise or lower the horizontal height of the tidal current power generating set, improve the adjustment efficiency of the horizontal height of the tidal current power generating set, improve the maintenance efficiency of the tidal current power generating set, adaptively adjust the horizontal height and orientation of the tidal current power generating set according to the change of the speed and direction of the water flow, fully utilize the tidal current to generate power, improve the utilization rate of tidal current resources, improve the tidal current power generation efficiency, and solve the over-speed risk.

[0120] The horizontal height adjustment system of the tidal current power generating set has simple structure, low cost, convenient installation on the sea site, and simple operation.

[0121] In the horizontal height adjustment system of the tidal current power generating set, the fixed support structure can no longer use a large-diameter rock-embedded single pile foundation, but can support two relatively small-diameter pile foundations symmetrically installed on both sides of the tidal current power generating set. For example, the tidal current power generating set is located between the first pile foundation and the second pile foundation, and the center of the tidal current power generating set, the center of the first pile foundation, and the center of the second pile foundation can be located on the same plane. In this way, the tidal current power generating set can be away from the pile foundation, the water blocking effect is small, the vortex area behind the pile is small, the flow interference and vortex influence of the pile foundation on the water body are reduced, the vibration of the tidal current power generating set is avoided, the tidal current power generating set can be safely operated, and the influence on the power generation power of the tidal current power generating set is reduced.

[0122] Reference Figure 7 A step flow chart of a horizontal height adjustment method of a tidal current power generating set is shown, which can be applied to the horizontal height adjustment system of the tidal current power generating set mentioned above, such as the water flow detection device in the system.

[0123] In step S101, the speed of the water flow at multiple depths in the area where the horizontal height adjustment system of the tidal current power generating set is located and the main flow direction of the water flow are detected based on the water flow detection device.

[0124] In step S102, the target speed corresponding to the maximum power generation power of the tidal current power generating set is obtained.

[0125] The target speed of the water flow corresponding to the maximum power generation power of the tidal current power generating set is a constant value, which is determined before the tidal current power generating set is shipped. In this way, the target speed of the water flow corresponding to the maximum power generation power of the tidal current power generating set can be stored in the water flow detection device in the system in advance. In this way, in this step, the target speed of the water flow corresponding to the maximum power generation power of the tidal current power generating set stored in the water flow detection device in the system can be obtained.

[0126] In step S103, a target depth with a target speed is determined among the plurality of depths according to the speed of the water flow at each depth.

[0127] In the present application, after the speed of the water flow at each depth is obtained respectively, the depth whose speed of the water flow is the same as or closest to the target speed can be taken as the target depth.

[0128] In step S104, the depth where the tidal current generator set is currently located is determined.

[0129] The depth where the tidal current generator set is currently located can be detected in real time, and the present application does not limit the specific detection method of the depth where the tidal current generator set is currently located.

[0130] In step S105, it is determined whether the current depth is the same as the target depth.

[0131] In the case where the current depth is different from the target depth, in step S106, the first gear box and the second gear box are controlled to drive the transverse shaft to rotate around the central shaft of the transverse shaft, so as to adjust the depth where the tidal current generator set is located from the current depth to the target depth.

[0132] Alternatively, in the case where the current depth is the same as the target depth, the process can be ended, or the step S101 can be executed after a period of time, and the length of the period of time is not limited in the present application and can be determined according to actual conditions.

[0133] In an embodiment of the present application, the present step can be implemented through the following process, comprising:

[0134] 1061. Obtain the length of the longitudinal shaft.

[0135] The length of the longitudinal shaft is a constant value, which can be stored in the water flow detection device in the system in advance, so that the length of the longitudinal shaft stored in the water flow detection device in the system can be obtained.

[0136] 1062. According to the length of the longitudinal shaft, the current depth and the target depth, determine the adjustment amount of the angle between the longitudinal shaft and the sea level.

[0137] According to the length of the longitudinal shaft, the current depth and the target depth, the adjustment amount of the angle between the longitudinal shaft and the sea level is calculated according to the following formula:

[0138]

[0139] In the above formula, θ is the adjustment amount of the angle between the longitudinal shaft and the sea level, and L is the length of the longitudinal shaft.

[0140] Wherein, in the case that the current depth is less than the target depth, h1 is the current depth, and h2 is the target depth.

[0141] Or, in the case that the current depth is greater than the target depth, h1 is the target depth, and h2 is the current depth.

[0142] 1063、According to the adjustment amount of the included angle, the number of gears and the direction of rotation of the first gear box and the second gear box are determined.

[0143] In the present application, the first gear box and the second gear box can be the same gear box, for example, the same model gear box, etc. The rotation angle corresponding to one gear in different models of gear boxes is also different. The present application also supports the use of various models of first gear boxes and various models of second gear boxes in the system (but it is necessary to ensure that the first gear box and the second gear box are the same gear box).

[0144] When the number of gears and the direction of rotation of the first gear box and the second gear box are determined according to the adjustment amount of the included angle, the actual model of the first gear box and the second gear box can be determined. After the actual model of the first gear box and the second gear box is determined, how to determine the number of gears and the direction of rotation of the first gear box and the second gear box can be determined according to the existing method, which is not limited in the present application and will not be described in detail.

[0145] 1064、According to the number of gears and the direction of rotation of the first gear box and the second gear box, the first gear box and the second gear box are controlled to rotate.

[0146] Thus, the depth of the tidal current power generating set is adjusted from the current depth to the target depth.

[0147] In step S107, the current orientation of the impeller in the tidal current power generating set is obtained.

[0148] The current orientation of the impeller in the tidal current power generating set can be detected in real time, and the specific detection method of the current orientation of the impeller in the tidal current power generating set is not limited in the present application.

[0149] In step S108, it is determined whether the current orientation of the impeller and the main flow direction of the water flow differ by 180 degrees.

[0150] The current orientation of the impeller corresponds to one angle, and the main flow direction of the water flow corresponds to another angle. The absolute value of the difference between the two angles can be calculated. In the case where the absolute value is equal to 180 degrees, it can be determined that the current orientation of the impeller is different from the main flow direction of the water flow by 180 degrees. Or, in the case where the absolute value is not equal to 180 degrees, it can be determined that the current orientation of the impeller is not different from the main flow direction of the water flow by 180 degrees.

[0151] In the case where the current orientation of the impeller is not different from the main flow direction of the water flow by 180 degrees, in step S109, the steering motor is controlled to drive the longitudinal shaft to rotate around the central axis of the longitudinal shaft so that the orientation of the impeller in the tidal current power generation set is different from the main flow direction of the water flow by 180 degrees.

[0152] For example, it can be determined that the orientation of the impeller in the tidal current power generation set needs to be adjusted by a certain amplitude when the orientation of the impeller in the tidal current power generation set needs to be different from the main flow direction of the water flow by 180 degrees.

[0153] Then the amplitude is transmitted to the steering motor to drive the longitudinal shaft to rotate around the central axis of the longitudinal shaft by an angle corresponding to the amplitude, so that the orientation of the impeller in the tidal current power generation set is different from the main flow direction of the water flow by 180 degrees.

[0154] For the steering motor, the specific way of "the steering motor driving the longitudinal shaft to rotate around the central axis of the longitudinal shaft by an angle corresponding to the amplitude" can be the inherent way of the steering motor, which is not described here in detail.

[0155] In the case where the current orientation of the impeller is different from the main flow direction of the water flow by 180 degrees, the process can end, or return to execute step S101 after a period of time. The length of the period of time is not limited in the present application and can be determined according to actual conditions.

[0156] After step S101 is executed, step S102 and step S107 can be executed. Step S102 and step S107 can be executed in parallel or sequentially.

[0157] Steps S102 to S106 can be executed in sequence. Steps S107 to S109 can be executed in sequence.

[0158] By the adjusting method of the horizontal height of the tidal current generator set, the horizontal height of the tidal current generator set can be quickly and stably raised or lowered, the adjusting efficiency of the horizontal height of the tidal current generator set can be improved, the maintenance efficiency of the tidal current generator set can be improved, the horizontal height and the orientation of the tidal current generator set can be adaptively adjusted according to the change of the speed and the change of the direction of the water flow, the tidal current can be fully utilized for power generation, the utilization rate of the tidal current resource can be improved, the tidal current power generation efficiency can be improved, and the over-speed risk can be solved.

[0159] Further, referring to Figure 8 The method further comprises:

[0160] In step S201, it is detected whether the angle between the longitudinal shaft and the vertical direction changes.

[0161] The angle between the longitudinal shaft and the vertical direction can be understood as the angle between the direction of the central axis of the longitudinal shaft and the vertical direction.

[0162] In the case where the first gear box and the second gear box work to drive the transverse shaft to rotate with the central axis of the transverse shaft as the rotation axis, the angle between the longitudinal shaft and the vertical direction changes.

[0163] In this way, it can be detected whether the first gear box and the second gear box work to drive the transverse shaft to rotate with the central axis of the transverse shaft as the rotation axis.

[0164] In the case where the first gear box and the second gear box work to drive the transverse shaft to rotate with the central axis of the transverse shaft as the rotation axis, it can be determined that the angle between the longitudinal shaft and the vertical direction changes.

[0165] Alternatively, in the case where the first gear box and the second gear box do not work to drive the transverse shaft to rotate with the central axis of the transverse shaft as the rotation axis, it can be determined that the angle between the longitudinal shaft and the vertical direction does not change.

[0166] In the case where the angle between the longitudinal shaft and the vertical direction changes, step S202 can be performed.

[0167] Alternatively, in the case where the angle between the longitudinal shaft and the vertical direction does not change, step S201 is performed again after a period of time, and the specific length of the period of time can be determined according to actual conditions, which is not limited in the present application.

[0168] In the case where the angle between the longitudinal shaft and the vertical direction changes, in step S202, the changed angle between the longitudinal shaft and the vertical direction is obtained.

[0169] The first gear box and the second gear box work to drive the transverse shaft to rotate around the central shaft of the transverse shaft. After the rotation ends, the changed angle between the longitudinal shaft and the vertical direction can be detected in real time. The application does not limit the specific detection method.

[0170] In step S203, the height of the cross section of the longitudinal shaft is obtained.

[0171] In an embodiment of the application, the cross section of the long arm is an ellipse, and the direction of the major axis of the ellipse is parallel to the direction of the tidal current, which is beneficial to reduce the water flow resistance. The height of the cross section of the longitudinal shaft can be the length of the minor axis of the elliptical cross section of the longitudinal shaft, etc.

[0172] Alternatively, in another embodiment of the application, the cross section of the long arm is a rhombus, and the direction of the major axis of the rhombus is parallel to the direction of the tidal current, which is beneficial to reduce the water flow resistance. The height of the cross section of the longitudinal shaft can be the length of the minor axis of the rhombic cross section of the longitudinal shaft, etc.

[0173] The height of the cross section of the longitudinal shaft is a fixed value, which can be stored in the water flow detection device in the system in advance. The height of the cross section of the longitudinal shaft stored in the water flow detection device in the system can be directly obtained.

[0174] In step S204, according to the changed angle and the height of the cross section of the longitudinal shaft, the target difference value between the target extension length of the hydraulic rod of the first hydraulic assembly and the target extension length of the hydraulic rod of the second hydraulic assembly is obtained.

[0175] Referring to Figure 9 , a schematic diagram of an angle is shown.

[0176] According to the changed angle and the height of the cross section of the longitudinal shaft, the target difference value between the target extension length of the hydraulic rod of the first hydraulic assembly and the target extension length of the hydraulic rod of the second hydraulic assembly is calculated according to the following formula:

[0177] S = H*tanα

[0178] In the above formula, S is the target difference value. α is the changed angle, and H is the height of the cross section of the longitudinal shaft.

[0179] In step S205, the current difference value between the current extension length of the hydraulic rod of the first hydraulic assembly and the current extension length of the hydraulic rod of the second hydraulic assembly is obtained.

[0180] The water flow detection device in the system can detect the current difference value between the current extension length of the hydraulic rod of the first hydraulic assembly and the current extension length of the hydraulic rod of the second hydraulic assembly in real time.

[0181] In step S206, the length variation amount of the hydraulic rod of the first hydraulic assembly and the length variation amount of the hydraulic rod of the second hydraulic assembly that need to be adjusted are determined according to the current difference and the target difference.

[0182] In step S207, the first hydraulic rod is adjusted according to the length variation amount of the hydraulic rod of the first hydraulic assembly that needs to be adjusted, and the second hydraulic rod is adjusted according to the length variation amount of the hydraulic rod of the second hydraulic assembly that needs to be adjusted.

[0183] The extension length of the hydraulic rod of the first hydraulic assembly is the target extension length of the hydraulic rod of the first hydraulic assembly, and the extension length of the hydraulic rod of the second hydraulic assembly is the target extension length of the hydraulic rod of the second hydraulic assembly.

[0184] According to the application, in the case of the change of the angle between the longitudinal shaft and the vertical direction, the platform at the top of the tidal current generator set can be kept in a horizontal state, so as to improve the personal safety of the staff on the platform at the top of the tidal current generator set and the like.
