The pile column type tidal current power generation unit is implanted on a pile foundation, a tidal current power generation unit placing platform is installed on the pile foundation, the tidal current power generation unit is placed on the placing platform, and a lifting rod and a hydraulic system are installed on the top of the pile foundation. When the tidal current power generation unit operates, the working elevation thereof is below the water surface, and when maintenance is required, the tidal current power generation unit is gradually lifted out of the water surface under the driving of the lifting rod.

[0004] However, for the pile column type tidal current power generation unit, the following defects exist at present.

[0079] 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 only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0080] Referring to Figures 1-3 , a schematic diagram of a height adjustment system of a tidal current generator set of the present application is shown, which comprises:

[0081] The tidal current generator set 01.

[0082] The L-shaped rotating arm 02, see Figures 1-4 The L-shaped rotating arm has a long arm 021 and a short arm 022, and the long arm and the short arm can be perpendicular or close to perpendicular, so as to form the L-shaped rotating arm.

[0083] The end of the short arm is rotatably connected to the side of the pile foundation 03, and the end of the long arm is rotatably connected to the side of the tidal current generator set.

[0084] The lifting assembly 04 comprises a winch 041 and a rope 042. The winch is fixed on the top of the pile foundation, one end of the rope is fixed on the winch, and the other end of the rope is fixed on the side of the end of the long arm. The winch can adjust the rotation angle of the rotating arm (for example, adjust the height of the end of the long arm of the rotating arm, and the height of the end of the short arm of the rotating arm remains unchanged) by winding and unwinding the rope, so as to adjust the height of the tidal current generator set.

[0085] The tidal current generator set can adjust its direction to make the power generation mechanism (for example, a wind wheel) face the tidal current direction, thereby improving the power generation efficiency.

[0086] The lifting assembly is used to lift the height of the tidal current generator set. For example, the winch winds the rope to lift the rotation angle of the rotating arm (for example, to lift the height of the end of the long arm of the rotating arm), so as to lift the height of the tidal current generator set, for example, to make the tidal current generator set exposed on the sea surface, in a lifted state, which is convenient for the staff to maintain and overhaul the tidal current generator set.

[0087] The lifting assembly is also used to reduce the horizontal height of the tidal current power generator set. For example, the winch releases the rope to reduce the rotation angle of the rotating arm (for example, to reduce the height of the end of the long arm of the rotating arm), thereby reducing the horizontal height of the tidal current power generator set, for example, to make the tidal current power generator set located below the sea surface in a lowered state, in which the tidal current power generator set can work to generate power.

[0088] The application has flexible and stable adjustment of the horizontal height of the tidal current power generator set by the winch and the rope, large adjustment range, and low hardware cost.

[0089] Among them, Figure 1 FIG. 1 is a schematic view of an adjustment system for the horizontal height of a tidal current power generator set in a lowered state.

[0090] Figure 2 FIG. 2 is a schematic view of an adjustment system for the horizontal height of a tidal current power generator set in a lifted state.

[0091] Figure 3 FIG. 3 is a front view of the adjustment system for the horizontal height of the tidal current power generator set.

[0092] It should be noted that the end of the short arm can be directly rotationally connected with the side surface of the pile foundation, or a rotationally connecting structure can be installed on the side surface of the pile foundation, and the end of the short arm is rotationally connected with the connecting structure to indirectly realize the rotationally connection with the side surface of the pile foundation.

[0093] The application does not make specific limitation on the connection mode of the rotationally connection between the end of the short arm and the side surface of the pile foundation, as long as the rotating arm can rotate, the angle of the long arm of the rotating arm can change, and for example, the height of the end of the long arm of the rotating arm can change.

[0094] In an embodiment of the application, the rotationally connection between the end of the short arm and the side surface of the pile foundation can be hinged, and the rotationally connection between the end of the long arm and the side surface of the tidal current power generator set can be hinged.

[0095] Alternatively, in another embodiment of the application, the rotationally connection between the end of the short arm and the side surface of the pile foundation can be a spherical pair connection, and the rotationally connection between the end of the long arm and the side surface of the tidal current power generator set can be a spherical pair connection.

[0096] Alternatively, in another embodiment of the application, the side surface of the pile foundation is provided with a flange plate. The end of the short arm is provided with a rotary bearing. The rotationally connection between the end of the short arm and the side surface of the pile foundation is realized through the mutual cooperation between the rotary bearing and the flange plate.

[0097] The rotating bearing cooperates with the flange plate, which is beneficial to installation and disassembly, and can tightly connect the end of the short arm and the side surface of the pile foundation, so that the vibration and displacement generated by the rotating arm in the rotating process are effectively controlled, thereby improving the stability of rotation. In the rotating process, the rotating bearing and the flange plate can bear stress uniformly, avoiding damage or failure caused by stress concentration, and prolonging the service life of the components.

[0098] The flange plate is arranged at a specific position of the side surface of the pile foundation. The distance (value) between the specific position and the seabed is equal to half of the water depth (value) of the area where the pile foundation is located.

[0099] In the present application, the working height of the tidal current generator set can be half of the water depth of the area where the pile foundation is located (the distance between the tidal current generator set and the seabed is equal to half of the water depth of the area where the pile foundation is located), and through statistics, in most cases, the tidal current generator set is located at a height of half of the water depth of the area where the pile foundation is located, so that the flange plate is at the same height as the working height of the tidal current generator set, and the L-shaped rotating arm does not need to be lifted, and the internal stress is minimized. Therefore, the flange plate arranged at the specific position of the side surface of the pile foundation can avoid damaging the horizontal height adjustment system of the tidal current generator set as much as possible, and is beneficial to improving the service life of the horizontal height adjustment system of the tidal current set.

[0100] In another embodiment of the present application, the cross section of the long arm is elliptical. The direction of the long axis of the ellipse is parallel to the direction of the tidal current, which is beneficial to reducing the water flow resistance. The direction of the long axis of the ellipse can be horizontal (whether the rotating arm is rotating or not).

[0101] Alternatively, in another embodiment of the present application, the cross section of the long arm is rhombus. The direction of the long axis of the rhombus is parallel to the direction of the tidal current, which is beneficial to reducing the water flow resistance. The direction of the long axis of the rhombus can be horizontal (whether the rotating arm is rotating or not).

[0102] In another embodiment of the present application, the other end of the rope is anchored on the side surface of the end of the long arm.

[0103] In another embodiment of the present application, the top of the tidal current generator set has a platform, and the periphery of the platform is provided with a fence, which can improve the safety of the workers when working on the platform at the top of the tidal current generator set.

[0104] In another embodiment of the present application, a ladder is arranged on the side surface 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.

[0105] In another embodiment of the present application, the top of the winch is provided with a warning assembly to warn passing ships, reducing the risk of collision between the adjustment system for reducing the horizontal height of the tidal current generator set and other ships, and improving safety.

[0106] In another embodiment of the present application, referring to Figures 5-7 , the tidal current generator set is two, which are a first tidal current generator set and a second tidal current generator set.

[0107] The L-shaped rotating arms are two, which are a first L-shaped rotating arm and a second L-shaped rotating arm.

[0108] The end of the short arm of the first L-shaped rotating arm is rotatably connected to the first side of the pile foundation, and the end of the short arm of the second L-shaped rotating arm is rotatably connected to the second side of the pile foundation, the first side and the second side being opposite sides or facing away sides in the pile foundation.

[0109] The long arms of the first L-shaped rotating arm and the second L-shaped rotating arm are symmetrically arranged (or oppositely arranged, etc.) on both sides of the pile foundation, so that the first tidal current generator set and the second tidal current generator set are symmetrically distributed (or oppositely distributed, etc.) on both sides of the pile foundation.

[0110] Alternatively, a line is formed between the position of the end of the short arm of the first L-shaped rotating arm rotatably connected to the pile foundation and the position of the end of the short arm of the second L-shaped rotating arm rotatably connected to the pile foundation. The line and the vertical axis on which the pile foundation is located form a plane, the long arm of the first L-shaped rotating arm is located on one side of the plane, and the long arm of the second L-shaped rotating arm is located on the other side of the plane.

[0111] Alternatively, from a top view, the long arms of the first L-shaped rotating arm and the second L-shaped rotating arm are centrally symmetric with respect to the pile foundation.

[0112] Alternatively, from a top view, the long arms of the first L-shaped rotating arm and the second L-shaped rotating arm are respectively located on both sides of the pile foundation.

[0113] In this way, it is beneficial to improve the lifting of the assembly, can prevent the two rotating arms from colliding with each other during the activity, and improve the overall safety.

[0114] The end of the long arm of the first L-shaped rotating arm is rotatably connected to the side of the first tidal current generator set.

[0115] The end of the long arm of the second L-shaped rotating arm is rotatably connected to the side of the second tidal current generator set.

[0116] The ropes in the lifting assembly are two, which are a first rope and a second rope.

[0117] The first rope and the second rope share one winch of the lifting assembly.

[0118] One end of the first rope is fixed on the winch, and the other end of the first rope is fixed on the side of the end of the long arm of the first L-shaped rotating arm.

[0119] One end of the second rope is fixed on the winch, and the other end of the second rope is fixed on the side of the end of the long arm of the second L-shaped rotating arm.

[0120] The winch has the function of simultaneously winding and unwinding the first rope and the second rope, for example, the winch is used to simultaneously wind and unwind the first rope and the second rope to simultaneously adjust the horizontal height of the first tidal current generator set and the horizontal height of the second tidal current generator set.

[0121] In addition, the winch can also wind and unwind the first rope and the second rope separately, for example, the first rope is wound and unwound without winding and unwinding the second rope, or the second rope is wound and unwound without winding and unwinding the first rope.

[0122] In this application, the pile foundation is connected with the tidal current generator set through the rotating arm, the tidal current generator set is away from the pile foundation, the tidal current generator set does not directly occupy too much area of the side of the pile foundation, the same pile foundation can carry two tidal current generator sets, the number of pile foundations is reduced, the cost is reduced, the energy capture efficiency is improved, and the two tidal current generator sets can share one winch in the lifting assembly, thereby saving cost.

[0123] Among them, Figure 5 is a schematic diagram of the horizontal height adjustment system of the tidal current generator set in the lowered state.

[0124] Figure 6 is a schematic diagram of the horizontal height adjustment system of the tidal current generator set in the lifted state.

[0125] Figure 7 is a front view of the horizontal height adjustment system of the tidal current generator set.

[0126] In another embodiment of the present application, the system further comprises a hydraulic assembly.

[0127] The hydraulic body of the hydraulic assembly is connected with the side of the tidal current generator set, for example, fixedly connected or rotatably connected, the side of the tidal current generator set rotatably connected with the end of the long arm and the side of the tidal current generator set connected with the hydraulic body are the same side.

[0128] The hydraulic body comprises a hydraulic cylinder and the like.

[0129] The rotation connection between the hydraulic body of the hydraulic assembly and the side surface of the tidal current generator set is not limited in the application, which can be hinged or connected by a spherical pair.

[0130] The hydraulic rod of the hydraulic assembly is connected to the side surface of the end of the long arm, for example, fixedly or rotatably.

[0131] The hydraulic assembly is used to adjust the extension length of the hydraulic rod to adjust the included angle between the side surface of the tidal current generator set and the long arm of the rotating arm, so as to adjust the horizontal angle of the platform at the top of the tidal current generator set, for example, to make the platform at the top of the tidal current generator set horizontal, so as to improve the personal safety of the staff on the platform at the top of the tidal current generator set, etc.

[0132] The number of the hydraulic rod in the hydraulic assembly is not limited in the application, which can be one or multiple, etc.

[0133] In addition, the number of the hydraulic assembly is not limited in the application, which can be one or multiple, etc.

[0134] In the tidal current generator set of the application, there are two wind wheels, for example, a first wind wheel and a second wind wheel, which are arranged at opposite or facing away sides of the tidal current generator set, and the two sides are different from the side surface of the end of the rotating connection long arm in the tidal current generator set.

[0135] In the application, in the scenario of rising tide, the first wind wheel works to generate electricity, and the second wind wheel does not work, and in the scenario of falling tide, the second wind wheel works to generate electricity, and the first wind wheel does not work, so that the tidal current generator set of the application can generate electricity in the scenarios of rising tide and falling tide, and the power generation efficiency can be improved.

[0136] In the application, the horizontal height adjustment system of the tidal current generator set comprises: a tidal current generator set; an L-shaped rotating arm having a long arm and a short arm, the end of the short arm being rotationally connected to the side surface of the pile foundation, and the end of the long arm being rotationally connected to the side surface of the tidal current generator set; a lifting assembly comprising a winch and a rope; the winch is fixed on the top of the pile foundation, one end of the rope is fixed on the winch, and the other end of the rope is fixed on the side surface of the end of the long arm; the winch is used to wind and unwind the rope to adjust the rotation angle of the rotating arm, and then adjust the horizontal height of the tidal current generator set.

[0137] Through the horizontal height adjustment system of the tidal current generator set of the application, the tidal current generator set can be quickly and stably lifted or lowered, the adjustment efficiency of the horizontal height of the tidal current generator set can be improved, and then the maintenance efficiency of the tidal current generator set can be improved.

[0138] The height adjustment system of the tidal current generator set has simple structure and low cost.

[0139] The height adjustment system of the tidal current generator set of the application can make the tidal current generator set away from the pile foundation, reduce the interference and vortex influence of the pile foundation on the water body, avoid the vibration of the tidal current generator set, and enable the tidal current generator set to operate safely.

[0140] Referring to Figure 8 , a step flow chart of a horizontal angle adjustment method of a tidal current generator set of the application is shown, which can be applied to the height adjustment system of the tidal current generator set mentioned above, for example, the hydraulic assembly in the system, and the controller in the hydraulic assembly, etc.

[0141] The method comprises:

[0142] In step S101, it is detected whether the angle between the long arm of the L-shaped rotating arm and the horizontal plane changes.

[0143] In the case where the winch works to collect the rope, or in the case where the winch works to release the rope, the angle between the long arm of the L-shaped rotating arm and the horizontal plane changes.

[0144] In this way, it can be detected whether the winch works to collect the rope or the winch works to release the rope.

[0145] In the case where the winch works to collect the rope or the winch works to release the rope, it can be determined that the angle between the long arm of the L-shaped rotating arm and the horizontal plane changes.

[0146] Or, in the case where the winch does not work to collect the rope and the winch does not work to release the rope, it can be determined that the angle between the long arm of the L-shaped rotating arm and the horizontal plane does not change.

[0147] In the case where the angle between the long arm of the L-shaped rotating arm and the horizontal plane changes, step S102 can be performed.

[0148] Or, in the case where the angle between the long arm of the L-shaped rotating arm and the horizontal plane does not change, step S101 is returned to be performed 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 application.

[0149] In the case where the angle between the long arm of the L-shaped rotating arm and the horizontal plane changes, in step S102, the changed angle between the long arm of the L-shaped rotating arm and the horizontal plane is obtained. In the case where the angle between the long arm of the L-shaped rotating arm and the horizontal plane changes, in step S102, the changed angle between the long arm of the L-shaped rotating arm and the horizontal plane is obtained.

[0150] The changed angle between the long arm of the L-shaped rotating arm and the horizontal plane after the rotation is completed can be detected in real time. The specific detection method is not limited in the present application.

[0151] For another example, the angle between the long arm and the short arm of the rotating arm is a constant value, and thus the changed angle between the short arm of the L-shaped rotating arm and the horizontal plane can be detected, and thus the changed angle between the long arm of the L-shaped rotating arm and the horizontal plane can be determined according to the changed angle between the short arm of the L-shaped rotating arm and the horizontal plane.

[0152] In step S103, the height of the cross section of the long arm of the L-shaped rotating arm is obtained.

[0153] In an embodiment of the present application, the cross section of the long arm is an ellipse, and the direction of the long axis of the ellipse is parallel to the direction of the tidal current, which is beneficial to reduce the water flow resistance. The direction of the long axis of the ellipse can be the horizontal direction (whether the rotating arm is rotating or not), and thus the height of the cross section of the long arm of the L-shaped rotating arm can be the length of the short axis of the long arm of the L-shaped rotating arm, etc.

[0154] Alternatively, in another embodiment of the present application, the cross section of the long arm is a rhombus, and the direction of the long axis of the rhombus is parallel to the direction of the tidal current, which is beneficial to reduce the water flow resistance. The direction of the long axis of the rhombus can be the horizontal direction (whether the rotating arm is rotating or not), and thus the height of the cross section of the long arm of the L-shaped rotating arm can be the length of the short axis of the long arm of the L-shaped rotating arm, etc.

[0155] The height of the cross section of the long arm of the L-shaped rotating arm is a constant value, which can be stored in the controller in the hydraulic assembly in advance. The controller in the hydraulic assembly can directly obtain the height of the cross section of the long arm of the L-shaped rotating arm which has been stored.

[0156] In step S104, the target extension length of the hydraulic rod in the hydraulic assembly is obtained according to the changed angle and the height of the cross section of the long arm of the L-shaped rotating arm.

[0157] Referring to FIG. 1, Figure 9 which shows a schematic diagram of an angle, and thus in the present step, the target extension length of the hydraulic rod in the hydraulic assembly can be calculated according to the changed angle and the height of the cross section of the long arm of the L-shaped rotating arm according to the following formula:

[0158] S=L*tanθ

[0159] In the above formula, S is the target extension length of the hydraulic rod in the hydraulic assembly. θ is the changed angle, and L is the height of the cross section of the long arm of the L-shaped rotating arm.

[0160] In step S105, the current extension length of the hydraulic rod is acquired.

[0161] The controller in the hydraulic assembly can detect the current extension length of the hydraulic rod in real time.

[0162] The current extension length of the hydraulic rod is detected, for example, by a resistance sensor, an inductive sensor or a displacement sensor.

[0163] In step S106, the length variation that the hydraulic rod needs to adjust is determined according to the current extension length and the target extension length.

[0164] For example, the difference between the target extension length and the current extension length can be calculated and used as the length variation that the hydraulic rod needs to adjust. The difference can be greater than 0 or less than 0, so the length variation that the hydraulic rod needs to adjust can be greater than 0 or less than 0.

[0165] In step S107, the hydraulic rod is adjusted according to the length variation.

[0166] In the case where the length variation is greater than 0, it indicates that the hydraulic rod needs to continue extending by the length variation on the basis of the current extension length, so the hydraulic rod can be controlled to continue extending by the length variation on the basis of the current extension length, so as to keep the platform at the top of the tidal current generator set in a horizontal state.

[0167] Alternatively, in the case where the length variation is less than 0, it indicates that the hydraulic rod needs to retract by the length variation on the basis of the current extension length, so the hydraulic rod can be controlled to retract by the length variation on the basis of the current extension length, so as to keep the platform at the top of the tidal current generator set in a horizontal state.

[0168] According to the present application, in the case where the angle between the long arm of the L-shaped rotating arm and the horizontal plane changes, the platform at the top of the tidal current generator set can be kept in a horizontal state, so the personal safety of the workers on the platform at the top of the tidal current generator set can be improved.

[0169] It should be noted that, for the method embodiments, in order to simply describe, they are all described as a series of action combinations, but those skilled in the art should know that the present application is not limited to the action sequence described, because according to the present application, certain steps can be performed in other sequences or at the same time.
