[0002] Offshore wind turbines are wind turbine generator systems used for offshore wind power generation. Compared to onshore wind turbines, they have higher technical requirements and cover a wider range of disciplines and specialties. Offshore wind turbines are generally modified from onshore wind turbines. To address offshore resource and environmental conditions, corresponding or specialized technical improvements have been made to the foundation, corrosion protection, dehumidification, transportation, installation, and maintenance requirements.

[0003] As a type of offshore generator, floating wind turbines can operate almost anywhere on the sea, but they still have the following problems when used:

[0004] Traditional floating wind turbines float on buoys, which are fixed. In the event of strong winds, the center of gravity of the generator set may shift excessively, affecting the stability and service life of the unit. Summary of the Invention

[0005] In view of this, the present invention provides an offshore floating wind turbine in order to solve the problem in the prior art that traditional floating wind turbines float by means of buoys, while the traditional buoys are fixed and easily cause the center of gravity of the generator set to shift excessively in the event of strong winds, thereby affecting the stability and service life of the generator set.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] An offshore floating wind turbine, comprising:

[0008] The chassis has a mounting plate connected to the top of the chassis in a circumferential rotation, the upper surface of the mounting plate is provided with a wind turbine body, the upper surface of the mounting plate is fixedly connected to a group of fixed floating blocks, and the upper surface of the mounting plate is slidably connected to a penetrating movable floating block;

[0009] The upper surface of the mounting plate is fixedly connected to a fixing frame, the top inner wall of the fixing frame is fixedly connected to a fixing seat, an electric push rod is rotatably connected between the two sides of the fixing seat, a sliding groove is opened on one side of the movable floating block, a sliding seat is slidably connected in the sliding groove, and the sliding seat is rotatably connected to one end of the output shaft of the electric push rod;

[0010] The driving component is arranged on the surface of the mounting plate to control the direction of the mounting plate.

[0011] Furthermore, the drive assembly includes a mounting cylinder and a mounting bracket. The mounting cylinder is fixedly connected to the upper surface of the mounting plate. The top inner wall of the mounting cylinder is fixedly connected to the reducer. The mounting bracket is fixedly connected to the circumferential inner wall of the support column. The top of the mounting bracket and one end of the reducer output shaft are fixedly connected to gears, and the two gears are meshed.

[0012] Furthermore, a floating plate is rotatably connected between two sides of the chassis away from one end of the wind turbine body, and a first pressure rod is fixedly connected to one side of the movable floating block.

[0013] Furthermore, the bottom of the first pressure rod is rotatably connected to a roller.

[0014] Furthermore, a spring is fixedly connected to the bottom of the slide groove, and the other end of the spring is fixed to the sliding seat.

[0015] Furthermore, the upper surface of the mounting plate is fixedly connected to two fixed plates, and a mounting shaft is rotatably connected between the two fixed plates. The circumference of the mounting shaft is fixedly connected to a force plate, and the circumference of the mounting shaft is fixedly connected to two second pressure rods.

[0018] The beneficial effects of the present invention are:

[0019] 1. The offshore floating wind turbine disclosed in the present invention can set the buoyancy of the wind turbine through movable floats. When encountering severe weather, the movable floats can be pushed downward by activating an electric push rod, thereby increasing the buoyancy of one end of the unit to resist wind force and improve the unit's wind resistance.

[0020] 2. The offshore floating wind turbine disclosed in the present invention has a floating plate installed at one end of the mounting plate, so that when the movable floating plate moves downward, the floating plate can be pushed to rotate by a first pressure rod, so that the floating plate is at a certain angle. Then, when the seawater flows with the wind, the inclined floating plate provides a lifting force at one end of the unit, which cooperates with the movable floating block to improve the wind resistance of the unit.

[0021] 3. The offshore floating wind turbine disclosed in the present invention, through the setting of a floating frame, enables the load-bearing plate to rotate when blown by the wind, and then presses the floating frame downward through a second pressure rod to increase the buoyancy of the floating frame, thereby counteracting the wind force. Similarly, when the wind is weak, the floating frame resets to improve the stability of the unit.

[0022] 4. The offshore floating wind turbine disclosed in the present invention can, in severe weather, activate an electric push rod to push the movable float downward, thereby increasing the buoyancy of one end of the unit to resist wind force and improve the wind resistance of the unit. At the same time, the inclined float plate provides one end of the unit with a lifting force, which cooperates with the movable float to improve the wind resistance of the unit. The floating frame also improves the stability of the unit.

[0034] like Figure 1-Figure 5The shown offshore floating wind turbine has a mounting plate 7 connected to the top of the chassis 1 in a circular rotation, and a wind turbine body 4 is provided on the upper surface of the mounting plate 7. The wind turbine body 4 is a prior art technology and can generate electricity using wind power. Its working principle will not be repeated here. A group of fixed floating blocks 5 are fixedly connected to the upper surface of the mounting plate 7, and a movable floating block 6 is slidably connected to the upper surface of the mounting plate 7. A plurality of pull ropes 2 are fixedly connected to the bottom of the chassis 1, and the pull ropes 2 are used to fix the unit. A scale 18 is fixedly connected to one side of the fixed floating block 5 and the movable floating block 6. The scale 18 is convenient for people to observe the height of the unit.

[0035] The upper surface of the mounting plate 7 is fixedly connected to a fixing frame 12, and the top inner wall of the fixing frame 12 is fixedly connected to a fixing seat 13, and an electric push rod 15 is rotatably connected between the two sides of the fixing seat 13. A slide groove 16 is provided on one side of the movable float 6, and a sliding seat 14 is slidably connected in the slide groove 16. The sliding seat 14 is rotatably connected to one end of the output shaft of the electric push rod 15. When the weather is windy, the electric push rod 15 is started, and the electric push rod 15 pushes the sliding seat 14 to move downward, thereby driving the movable float 6 to move downward, increasing the buoyancy of the movable float 6, thereby resisting the wind force and improving the stability of the unit.

[0036] The bottom of the slide groove 16 is fixedly connected with a spring 17, and the other end of the spring 17 is fixed to the sliding seat 14. The spring 17 is used to give the movable floating block 6 a certain buffering ability to avoid hard contact.

[0037] The driving assembly is arranged on the surface of the mounting plate 7 to control the direction of the mounting plate 7.

[0038] Reference Figure 2 The driving assembly includes a mounting cylinder 8 and a mounting frame 11. The mounting cylinder 8 is fixedly connected to the upper surface of the mounting plate 7. The top inner wall of the mounting cylinder 8 is fixedly connected to the reducer 9. The mounting frame 11 is fixedly connected to the circumferential inner wall of the support column 3. The top of the mounting frame 11 and one end of the output shaft of the reducer 9 are fixedly connected with a gear 10. The two gears 10 are engaged, and the reducer 9 is started. The reducer 9 drives the mounting cylinder 8 and the mounting plate 7 to rotate through the gear 10, so that the wind turbine body 4 faces the direction of the wind, which is convenient for power generation.

[0039] Reference Figure 4 A floating plate 19 is rotatably connected between the two sides of the chassis 1 away from one end of the wind turbine body 4, a first pressure rod 20 is fixedly connected to one side of the movable floating block 6, and a roller 21 is rotatably connected to the bottom of the first pressure rod 20.

[0040] Reference Figure 5The upper surface of the mounting plate 7 is fixedly connected to two fixing plates 22, and a mounting shaft 23 is rotatably connected between the two fixing plates 22. The circumference of the mounting shaft 23 is fixedly connected to the force-bearing plate 24, and the circumference of the mounting shaft 23 is fixedly connected to two second pressure rods 25. The upper surface of the mounting plate 7 is provided with two symmetrically arranged avoidance slides 26 used in conjunction with the two second pressure rods 25. A floating frame 27 is slidably connected between the two avoidance slides 26. One side of the floating frame 27 is provided with two penetrating through-holes 30. A pressure shaft 29 is fixedly connected between the two sides of the two through-holes 30. The two second pressure rods 25 pass through the two through-holes 30 respectively and contact the bottom circumference of the two pressure shafts 29. Both sides of the floating frame 27 are fixedly connected to the limit rod 28, and the limit rod 28 is slidably connected to the avoidance slide 26. When the wind blows the force-bearing plate 24 to rotate, the force-bearing plate 24 drives the mounting shaft 23 and the second pressure rod 25 to rotate. The second pressure rod 25 presses the floating frame 27 downward, thereby balancing the buoyancy of the unit and improving the stability of the unit.

[0041] However, as is well known to those skilled in the art, the working principles and wiring methods of the wind turbine body 4 and the electric push rod 15 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0042] When the offshore floating wind turbine is in use, the unit is fixed by a pull rope 2, and the unit is floated by a fixed float 5 and a movable float 6. The reducer 9 is started, and the reducer 9 drives the mounting cylinder 8 and the mounting plate 7 to rotate through the gear 10, so that the wind turbine body 4 faces the direction of the wind, which is convenient for power generation.

[0043] When encountering severe windy weather, the electric push rod 15 is started, and the electric push rod 15 pushes the sliding seat 14 to move downward, thereby driving the movable float 6 to move downward, increasing the buoyancy of the movable float 6, thereby resisting the wind and improving the stability of the unit. When the movable float 6 moves downward, it drives the first pressure rod 20 to move downward, and the first pressure rod 20 pushes the float plate 19 to rotate, so that the float plate 19 presents a certain angle, and then uses the sea water moving with the wind to push the float plate 19, and then cooperates with the movable float 6 to resist the wind. When the wind speed is normal, the force-bearing plate 24 is blown to rotate, and the force-bearing plate 24 drives the mounting shaft 23 and the second pressure rod 25 to rotate. The second pressure rod 25 presses the floating frame 27 downward, thereby balancing the buoyancy of the unit and improving the stability of the unit.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions, which should all be included in the scope of the claims of the present invention.
